# VYNDR — Build State

## Last Updated
2026-07-11

## Session S10 (a1 board, 2026-07-11) — Public Ledger Profiles v1 ✅
Stage-3 seed (Strava for betting), zero out-of-pocket. Branch off
day1/a1-board (aaafc3e). 2574 → **2612 tests** (220 suites), web build
exit 0. Spec: `specs/a1-s10-public-profiles.md`.
- **Migration `022_public_profiles.sql`** — COMMITTED, NOT APPLIED (founder
  applies migrations). `public_profiles` (user_id PK → auth.users, handle
  UNIQUE + regex CHECK, `published` DEFAULT FALSE). RLS: published rows
  readable by anyone, own row by owner, writes service-role only.
- **API** — `/api/profiles`: `GET/POST /me` (requireAuth; handle regex 400,
  taken handle 409, published only flips on explicit boolean true) and
  public `GET /:handle` (published → user-scoped 30d aggregate + settled
  rows newest 50, same columns as /api/ledger; unknown AND unpublished →
  byte-identical 404 — no existence leak). `getModelAggregate` gained a
  `userId` option (public `.is('user_id', null)` default untouched).
- **Frontend** — `/u/[handle]` (PUBLIC, in OPEN_ROUTES): server shell with
  "CLV-verified record — @handle · VYNDR" metadata + client record (hit% +
  beat-close% at n≥20 else RECORD BUILDING; outcome + CLV chips) + OG card
  (Node runtime, never edge). Settings PUBLIC PROFILE section: claim handle
  + one explicit publish toggle with the private-by-default copy.
- **Next**: profile OG card could embed the live record once n≥20 profiles
  exist; user-scan settlement coverage beyond MLB is the limiting factor.

## Session S3 (a1 board, 2026-07-11) — Affiliate + Partnership Plumbing ✅
Zero out-of-pocket; everything config-flip-ready but DISABLED/organic.
2398 → **2439 tests** (209 suites), web build exit 0.
- **BOOK IT deep links** — `web/src/lib/bookLinks.js` + `affiliateConfig.js`
  (every book `enabled:false`; Impact/Partnerize param shapes documented).
  StatStrip BOOK IT is a real anchor now (organic); scan hand-off links moved
  to the builder. Every book anchor renders `rel="sponsored noopener noreferrer"`.
- **Best-price marker** — `slateAdapter.detectBestBook` (≥2 books, SAME line,
  differing prices, else null) + green dot in StatStrip; `books[]` (the grouped
  odds rows) now threads Slate → strips instead of being discarded by pickLine.
- **Partner refs** — `?ref=CODE` → 90d first-party `vyndr_ref` cookie
  (first-touch, `PartnerRefCapture` in layout) → signup metadata `partner_ref`
  → internal `GET /api/partners/report/:code` (zeros + note until the TODO
  migration in docs/PARTNERS.md adds `user_profiles.partner_ref`; NOT run).
- **docs/PARTNERS.md** — ref link spec, Stripe promo-code mapping convention
  (partner code == promotion code), TODO migration SQL.
## Session S7 (a1 board, 2026-07-11) — Newsletter: THE VYNDR REPORT ✅

Branch off day1/a1-board (e4d2e79). 2398 → **2429 tests** (207 suites),
web build exit 0. Spec: `specs/feature-a1-s7-newsletter.md`. Runbook:
`docs/NEWSLETTER.md`.
- **Capture**: `NewsletterCapture` (dark terminal, mono data) on the landing
  (below FAQ) + `/welcome` (the real signup success surface — the signup
  "done" card auto-redirects in 1.5s, useless for a form). Double-opt-in
  note under the field; "Signups open soon" when Listmonk env is unset.
- **Backend**: `POST /api/newsletter/subscribe` (public, 10/min IP limit,
  honeypot, server-side email validation) → Listmonk subscribers API with
  `preconfirm_subscriptions:false` (Listmonk sends the confirmation).
  No env → calm 200 `{ ok:false, reason:'not configured' }`. Next proxy
  `web/src/app/api/newsletter/subscribe/route.ts` (S25 rule).
- **Assembly**: `newsletterService.buildDailyReport` — signals from
  `snapshot:{sport}:latest`, STREAK WATCH via rosterLogs → streaksService →
  streakLens (one row per player), THE RECORD via `getModelAggregate`
  (percentage ONLY when hit_pct != null — the n≥20 gate — else
  "RECORD BUILDING · N pending"). RG footer (21+, 1-800-GAMBLER,
  `{{ UnsubscribeURL }}`) in html + text. VOICE lint locked by tests:
  no `!`, no banned vocabulary, numbers only from injected pipeline data.
- **Send**: `sendDailyReport` creates + starts a Listmonk campaign;
  operator-triggered ONLY via `POST /api/internal/newsletter/send`
  (internal key). NOT scheduled. Empty report (0 signals + 0 streaks)
  refuses to send.
- **Env for Coolify** (all four required, else graceful no-op):
  `LISTMONK_URL`, `LISTMONK_USER`, `LISTMONK_TOKEN`, `LISTMONK_LIST_ID`.
## Session S2 (a1 board, 2026-07-11) — BUILT ✅ COMPLIANCE + APPROVAL PACK

Branch worktree off `day1/a1-board`. 2429 tests (206 suites), web build
exit 0 (`next build --webpack`). No backend routes touched.
- **/responsible-gambling REBUILT sincerely** — 21+, 1-800-GAMBLER
  (1-800-426-2537) as the primary helpline, 17-state resource list,
  warning signs, state self-exclusion guidance, links to the EXISTING
  /settings Responsible Play + Danger Zone surfaces. Zero marketing
  adjacency (no pricing/scan/upgrade links — a test enforces it).
- **/terms + /privacy redrafted** as honest approval-pack drafts (marked
  DRAFT: JULY 2026). Entity details are placeholder tokens Kev must fill:
  [ENTITY NAME], [STATE OF FORMATION], [ARBITRATION VENUE],
  [CONTACT EMAIL]. Privacy sub-processors now match reality (Stripe,
  Supabase, Resend, Sentry; PostHog described honestly — autocapture off,
  banner is disclosure-only, NOT consent-gated).
- **/methodology NEW** (server component + metadata, footer COMPANY link,
  OPEN_ROUTES): pipeline → engine → 11-step letter grades, refusals
  (insufficient_data), VYNDR Originals (41), Ledger settle (locked at
  grade time, box-score settle, CLV vs captured close, n≥20, public
  revisions), why misses are public.
- **/about audited** to North Star framing: data intelligence platform,
  THE PROOF card (Ledger + n≥20 + refusals + methodology link). Kept the
  "give it back" h1 (Phase-E test) + Wordmark (QA.5).
- **Footer**: helpline updated 1-800-522-4700 → 1-800-GAMBLER; Methodology
  link added. Compliance audit: footer is global in the root layout, no
  nested layout or CSS suppresses it on any page — zero pages missing it.
- **content/articles/** — 5 Ghost-ready seed drafts (front matter, VOICE
  v1.1, zero exclamation points, test-enforced) + docs/GHOST-PUBLISHING.md
  manual runbook (no Ghost credentials used; nothing auto-posts).
- Tests: tests/unit/compliancePages.test.js (31 assertions, source-text
  style).

## Current Phase
SHIP BUILD v59.0 — Overnight session: ledger team/opponent addendum,
work-order 1.6 closed (canonical player keys + slate join invariant),
Phase 2 slate UX, Phase 3 mobile P0. DEPLOY GATE: Coolify by Sat 10 AM ET;
first snapshot locks against freshly posted lines (manual internal trigger).

## Session 8 (A1 board, 2026-07-11) — SHIPPED ✅ OPS: THE PRODUCT WATCHES ITSELF

Branch off day1/a1-board tip. 2398 → 2437 tests (208 suites). Backend-only.
- **Settlement alarm** (`snapshotScheduler`): outcome/ledger settle pass
  THROW → ntfy high. Morning zero-settle alarm: ledger settle found
  pre-today Postgres rows but settled none → page once per ET date
  (signal = settleLedger's own return values — survives the Redis-TTL
  failure mode that silently killed morning settles in S60; documented in
  `opsWatch.zeroSettleAlarm`). Genuinely empty yesterday never alerts.
- **Persistent-failure pager** (`opsWatch.createFailureTracker`, pure):
  3 consecutive error / skipped-'no props' slots for a sport pages once
  (high); any good slot resets and re-arms. Single-slot misses stay quiet.
- **Quota** (`opsWatch.checkQuotaDaily`): odds-api ≥80% after a snapshot
  run → one alert/day, Redis-deduped (`ops:quota_day:{provider}:{date}`).
- **Box health** (`services/systemHealth`, pure + injectable): fs.statfs
  + os mem → `{disk_pct, mem_pct}`; pages high at disk>85 / mem>90.
- **Daily pulse** 13:00 UTC (9 AM EDT; `PULSE_HOUR_UTC` to move), ONE
  notification: ledger rows yesterday (`ledgerService.countRowsForDate`,
  'n/a' when Supabase off — never a fabricated 0), settles last 24h,
  quota pct, disk/mem, 'desk pack: see /desk'. Dedupe: in-process date +
  `ops:pulse:{date}`.
- **docs/OPS-RUNBOOK.md**: Uptime Kuma monitors (vyndr.app 200, api
  /api/health keyword 'healthy', /api/snapshot/summary), Coolify
  deploy-failure webhook → ntfy, ntfy phone-subscription steps.
- Live acceptance alert POSTed to ntfy.sh/vyndr-pipeline-kev2026.
- All alert copy VOICE v1.1 — deadpan, numbers, zero exclamation points
  (tests lint for `!`). Spec: `specs/session-8-ops-watch.md`.

## Session 60 (night2/full-board, 2026-07-11) — BUILT ✅ THE WHOLE BOARD (awaiting "merge the train")

Branch `night2/full-board` off d10bb4c — ZERO pushes to main. 2352 →
**2396 tests** (205 suites), web build exit 0. Sessions A–H all shipped:
- **A** AUTONOMY.md + P0: SNAP_TTL 6h→24h (the 11h overnight cron gap
  expired the snapshot before the morning settle — accuracy loop silently
  settled nothing; the Postgres ledger settle was immune).
- **B** Streaks engine RESURRECTED + fed: the snapshot pipeline now writes
  rosterlogs:{sport} from the stats it already fetches (producers were all
  external/unarmed — that's why panels never rendered). Form heat (hot
  hitters/sluggers/shooters, Σ/Σ rate math) + THE LENS (built-vs, tonight's
  matchup + opposing SP ERA, step-up/down, one-line read). LIVE acceptance:
  32 real rows (Turang 12-gm on-base, Reynolds 8-gm, Pratt 7-gm, Meidroth
  5-gm, Cortes 5-gm).
- **C** Aggregator mounted: Explore = SEO server shell + hub (leaders +
  full streaks + hot lists); streaks FREE for all tiers (the picture is
  free); landing teaser fixed (pointed at off-season NBA → never showed);
  one stat selection filters props+streaks+hotlists; player-dossier
  ACTIVE STREAKS block (+?player= on /api/streaks).
- **D** Phase 2.5: 20-min odds-only refresh in slate hours (skips snapshot
  slots, INTRADAY_REFRESH=0 kill switch, POST /api/internal/refresh/all).
  STEAM ▲ (with, no re-grade) / VALUE ▲ (against ≥1.0, re-grade holds) /
  PUBLIC revision (grade drops → revised_from_grade, strikethrough).
  Refresh-fidelity closing capture; ticker MOVEs at refresh frequency.
  Quota: ≤144 PropLine calls/day vs 9,000 free capacity. Post-deploy: set
  SNAPSHOT_EXPECTED_INTERVAL=1200 and SYNC goes live.
- **E** Phase 4: /api/players/search built (didn't exist — the Ohtani bug);
  nameKey fuzzy match live-verified vs the real 1,299-player list.
  §7 reveal (steps → DECLASSIFIED stamp → 90ms staggered panels,
  reduced-motion safe). PRIOR READS chips. Parlay: shared statLabel,
  1-leg provisional grade, Nav entry via window.__openParlay.
- **F** Phase 5: archetype definition line on-page; VYNDR-on-team
  (ModelRecord team scope); WNBA minutes-usage; Settings meter from the
  LIVE limiter (3/day free, 15/day analyst, ∞ desk); per-tier calibration
  chips (n≥20 PER TIER).
- **G** Phase 6: landing first-paint root cause KILLED (page blocked its
  render on Supabase auth init for anonymous visitors; now a sync
  localStorage gate — anon paints instantly). Proof Strip: A-tier-gated
  header, "TONIGHT'S BOARD" fallback, yesterday's settled reads with
  outcome chips when ungraded. /api/content/top-signals + /streak-watch
  (zero-grade format) + /daily-report (self-flags do_not_post until n≥20).
  Per-player OG images (Node runtime) + player metadata.
- **H** Design pass: QA.20–22 locks (STEAM amber/VALUE green/STALE-only
  red, revisions struck through, new data surfaces mono, honest waiting
  copy everywhere).

### The word: "merge the train" → main fast-forwards → Coolify ships board #2.

## Session 59 (2026-07-10 overnight) — SHIPPED ✅ ADDENDUM + 1.6 + PHASE 2 + PHASE 3

Backend 2327 → **2352 tests** (+25), 202 suites. Web build clean (exit 0).
Migration 020 (team/opponent) APPLIED while ledger_entries was at 0 rows —
zero backfill needed; VYNDR-on-team unblocked.

- **Task A** — `ledger_entries.team/opponent` populated in both write paths
  (pipeline: stats-resolve team + prop's other side via nickname match,
  NEVER guessed; scan: snapshot-grade team, opponent null). Roadmap: Phase
  4.5 (WNBA ESPN box-score settlement — DUE ~Jul 24) + Phase 5 calibration-
  by-grade-tier logged.
- **Task B (work-order 1.6 CLOSED)** — `mlbStatsAdapter.searchPlayer` now
  resolves via canonical `nameKey` (the old matcher DELETED accents:
  "Sánchez"→"snchez"≠"sanchez", then substring-guessed → wrong player's
  last-10). Fallback = UNIQUE last-name+first-initial or null.
  `buildPlayerStripsFromProps` gained the JOIN INVARIANT: a graded prop
  whose player's real team isn't a game participant is DROPPED (TB player
  can't render under MIL@PIT — suite fails if it regresses). Snapshot
  grades now carry `team`. Root cause of /team "No active props":
  grades:{sport} TTL (2h) < cron gap (5h) → now SNAP_TTL (6h).
- **Task C (Phase 2)** — 2.1 sport tabs are THE filter, URL-driven
  (?sport=, deep-linkable); the dashboard's duplicate legacy tablist is
  GONE (legacy sections subscribe via onTabChange). 2.2 cards cap at 6
  graded props sorted A+→F with "ALL N READS →" expanding in place.
  2.3 waiting states show the REAL next pipeline run ("Grades post
  ~6:00 PM ET" via lib/pipelineSchedule — mirrors SNAPSHOT_HOURS_UTC;
  update BOTH if the cron changes). 2.4 = TTL fix + join fix (verify on
  the live Yankees page post-deploy).
- **Task D (Phase 3)** — ROOT CAUSE of vanished mobile nav: HIDE_ON
  included '/' — the landing had NO nav at 390px (desktop links hidden,
  hamburger retired S37, tab bar suppressed). '/' removed. 3.2: html/body
  overflow-x hidden <768; GAME LINES collapses to a best-line summary +
  "N BOOKS ⌄" expander <640; venue (.gc-venue) drops first on phones.
- **Live verification:** raw ESPN (no date pin) STILL returns the Jun 13
  NYK@SA Finals game today; the pinned fetch returns 0 games, 0 off-date.

### Morning deploy runbook (Sat, before ~10 AM ET)
1. Push already sent to gitea (Coolify betonblk) — confirm deploy finished.
2. `GET /api/internal/snapshot/status` (x-internal-key) → cron_armed true.
3. When the day's lines post: `POST /api/internal/snapshot/all`
   (x-internal-key) → first public ledger rows lock against fresh lines.
4. Verify: `SELECT count(*), count(*) FILTER (WHERE team IS NOT NULL) FROM
   ledger_entries WHERE user_id IS NULL;` + one sample row.

## Session 58 (2026-07-10) — SHIPPED ✅ PHASE 1: TRUTH INFRASTRUCTURE

Backend 2309 → **2327 tests** (+18), 201 suites. Web build clean (exit 0).
Spec: `specs/phase-1-truth-infrastructure.md`. Migration
`supabase/migrations/019_ledger_entries.sql` APPLIED to prod (betonblk) —
dedupe (`UNIQUE NULLS NOT DISTINCT`) + RLS verified live (anon reads public
rows only; anon INSERT rejected 42501).

- **ledgerService** — recordPipelineGrades (public model record, idempotent
  ignoreDuplicates upsert), captureClosing (every snapshot overwrites today's
  closing_line/odds from the real feed; last write before game start = close),
  settleLedger (outcome + actual + SIGNED CLV: over = locked−closing),
  getModelAggregate (30d; percentages NULL under 20 settles). No-ops without
  SUPABASE env. `Number(null)===0` fabrication bug caught by tests → strict
  numOrNull everywhere.
- **Write paths:** snapshotService → ledger (user_id null, priority path);
  Next /api/scan → ledger row for AUTHED users only (anon would pollute the
  public record). Refused reads write NOTHING (no scan_history either) and
  don't burn a scan.
- **Honest refusal (work-order 1.5):** analyzeViaEngine1 returns
  `insufficient_data: true, grade: null` when the model has no projection
  (l5→l20→{stat}_per_90→xG for soccer). The web gradeAdapter no longer
  displays the LINE as the projection (the audit's model==line degenerate);
  GradeResultCard renders "—" absent states; scan page renders
  "INSUFFICIENT DATA — NO READ".
- **/ledger:** MY READS | MODEL tabs; model header shows "H-M · X% HIT ·
  Y% BEAT CLOSE" only at n≥20, else "RECORD BUILDING" + pending count.
  ModelRecord component mounted on landing + player hero (deferred-render).
- **SYNC (Task 5):** thresholds vs SNAPSHOT_EXPECTED_INTERVAL (default
  18000s): normal <1.5x · amber ≥1.5x · STALE red ≥3x.
- **Phase 2.5 LOGGED** in specs/vyndr-roadmap.md (intraday refresh +
  STEAM/VALUE/revision handling; build after Phase 3).
- **Settle trigger:** scheduler settle pass + POST /api/internal/ledger/settle.

## Session 57 (2026-07-10) — SHIPPED ✅ PHASE 0: KILL THE LIES

Backend 2289 → **2309 tests** (+20), 199 suites. Web build clean (exit 0).
Spec: `specs/phase-0-kill-the-lies.md`. Work order: Phase 0 of the
overhaul (audit-driven; Phases 1–6 queued).

### 0.1 — Fake NBA game (root cause found + fixed at the source)
- `scheduleService.fetchScheduleFromEspn` hit ESPN with NO `?dates=` param and
  NO date filter → off-season ESPN returns the NEAREST slate (the Jun 13 NYK@SA
  Finals game rendered as "tonight" all July). Now pins `?dates=YYYYMMDD` AND
  filters events to the requested ET date; undated events dropped.
- Honest per-sport empty states: `web/src/lib/emptyState.js` (month-aware —
  "NBA returns in October." vs in-season "No NBA games today."), used by the
  dashboard NO SLATE block + the Slate empty state.

### 0.2 — Fake header counters deleted
- `liveTick.js` stripped to `{ tick }` (1s re-render pulse only). The fake
  auto-incrementing "247 graded", sin-driven brain-%, aPlus/cascades: DEAD.
- New `GET /api/snapshot/summary` (public, cache-only, registered before
  `/:sport`) → `{ graded, updated_at, sports }`. Next proxy added.
- `HeartbeatBar` shows the REAL graded count + SYNC = elapsed since the last
  pipeline run (amber past 5 min). No data → "SYNC —", nothing invented.

### 0.3 — Ticker: real items only
- Nav's hardcoded fallback items (fake Wembanyama A+/"NYK vs SA Q3"/invented
  Tatum MOVE) deleted. MOVE stays — `computeLineDeltas` is real movement.
- Spec §3 rule: <4 real items → ticker renders nothing. It publishes
  `--ticker-h` (32px/0px) on `<html>`; layout main paddingTop and Slate sticky
  top are now `calc(base + var(--ticker-h))` so the header collapses cleanly.

### 0.4 — /terminal retired (fabricated surface)
- Route now `redirect('/dashboard')`. Layouts preserved UNROUTED at
  `web/src/components/intel/TerminalTemplates.tsx` (§12 content-engine
  templates — feed real data before ever routing them).
- Nav PRIMARY = Slate/Scan/Ledger. BottomTabBar: Terminal→Explore. PWA
  manifest shortcut Terminal→Ledger. routes.js: `/terminal` out of
  OPEN_ROUTES; `#terminal` → `/dashboard`.

### 0.5 — ›Query nav pill deleted (duplicate /scan link)

### Next (work order Phase 1 — starts the settle clock)
- `ledger_entries` table + write-on-grade (user scans AND pipeline pre-grades)
- Settlement worker; populate /ledger (personal + MODEL tabs)
- Degenerate scan output (model==line, +0% edge) → honest "INSUFFICIENT DATA"
- Canonical player_key normalization (blocks 2.4, 4.1)

## Session 56 (2026-07-10) — SHIPPED ✅ THE FULL AUDIT

Backend 2276 → **2289 tests** (+13), 197 suites. Web build clean (exit 0).
Docs: `specs/propline-audit.md`, `specs/vyndr-roadmap.md`,
`specs/audit-data/propline-audit-raw.json`, `scripts/propline-audit.js`.

### Research (Phases 1–3, 5) — verified against LIVE APIs
- Fetched real data: The Odds API `/v4/sports` (in-season now: MLB, WNBA, NFL
  preseason, NBA summer league, 40+ soccer leagues; NHL dark), a real MLB boxscore
  (Braves@Pirates 2026-07-09 — every settle field confirmed), ESPN WNBA/soccer
  scoreboards. PropLine inventory derived from code (no dev keys).
- **Headline bug found:** `oddsNormalizer` mapped `batter_rbis → 'rbis'` but the
  entire grade/feature/outcome chain keys on `'rbi'` → **every PropLine RBI prop
  silently failed to grade AND settle.** Fixed.
- Coverage truth: **MLB is the only end-to-end-live sport.** Outcome settlement is
  MLB-only (WNBA/NBA/soccer never settle → accuracy is MLB-only). Documented as
  the #1 roadmap gap.

### Phase 4 — wired missing MLB stat types (a full vertical slice)
- `batter_rbis → rbi` (unblocks a market already requested).
- PropLine MLB MARKETS 6 → 12: +batter_runs, +batter_walks, +batter_doubles,
  +pitcher_earned_runs, +pitcher_hits_allowed, +pitcher_outs (same request, no
  extra quota; runs/walks/earned_runs/hits_allowed were already supported
  downstream — just never asked for).
- `doubles` + `outs` (+`triples`) added to featureCache + outcomeService
  MLB_LOG_FIELD AND all three grade whitelists (analyze/scan/validation.py).

### Phase 6 — pipeline alerting + resilience
- **`src/utils/opsNotify.js`** — ntfy.sh push (`vyndr-pipeline-kev2026`), never
  throws, auto-disabled under test / `PIPELINE_ALERTS=0`. Injectable `fetchImpl`.
- `snapshotService.runSnapshot`: success alert ("✅ MLB snapshot: N graded, D
  deltas, X% accuracy"), stale alert (empty slate), failure alert; **retry-once**
  on a hard odds error/null (NOT on a legit empty slate — that's off-hours, not a
  failure).
- **Missed-cron watchdog:** `snapshotScheduler.mostRecentExpectedSlot` +
  `isSnapshotOverdue` (pure, tested); the tick alerts once per missed slot; the
  status probe (`GET /api/internal/snapshot/status`) now returns `overdue`.

### Phase 7 — the master roadmap
`specs/vyndr-roadmap.md` — priority-ordered Sessions 57–64 (WNBA/NBA settlement →
ESPN features → soccer e2e → live calibration → NFL/NBA readiness), stat-type +
sport coverage targets, operating invariants.

## Session 55 (2026-07-10) — SHIPPED ✅ SELF-LEARNING LOOP + REAL-TIME LAYER

Backend 2255 (4 failing) → **2274 tests** (all green; +19 new, +4 fixed), 196
suites. Web build clean (exit 0). Spec: `specs/session55-self-learning.md`.

### Phase 2 — the self-learning loop (the crown jewel; nothing like it existed)
- **`src/services/outcomeService.js`** — settles each locked snapshot grade
  against the REAL result (MLB Stats API game log — free, same source the grade
  pipeline uses) → hit/miss/push, aggregated by grade tier over a trailing 30-day
  window. Presence of a game-log row for the graded date ⇒ FINAL. Fully
  injectable → unit-tested with zero network. Idempotent (dedupe by
  `nameKey|stat|line|side|date`). NBA/WNBA degrade to `pending` (offline stats),
  never throw.
- **Redis:** `outcomes:{sport}:log` (settled, cap 1000), `accuracy:{sport}`,
  `accuracy:overall` ({ overall, byGrade } over 30d; pct excludes pushes).
- **Routes:** `GET /api/accuracy` (public, cached 5m), `GET /api/ledger/accuracy`
  (buckets — fills the pre-existing Next proxy that had no writer), internal
  `POST /api/internal/outcomes/:sport|/all`. Cron: `settleAllOutcomes()` runs on
  the snapshot scheduler tick BEFORE grading (settle yesterday, grade today).
- **UI:** `AccuracyBadge` (dashboard header + scan result + landing) — honest by
  construction: below MIN_SAMPLE (8) it reads "MODEL · LEARNING" (amber) instead
  of faking a number; above it, "A-RATED · 68% HIT · 30D" (green). Settled
  outcome chips (`✓ HIT (2)` / `✕ MISS`) on slate props via a snapshot-route
  overlay + `StatStrip.OutcomeChip`.

### Phase 1 — the real-time layer (make it feel ALIVE)
- **Slate auto-refresh:** silent 60s poll (no skeleton flash, never wipes a good
  view on a transient blip) + a "SIGNAL LIVE · N PROPS GRADED · M LIVE · UPDATED
  Xs ago" strip with a ticking freshness clock (`nowTick`, 15s).
- **Ticker:** anchored `LIVE` badge (pulsing dot) that flashes green when a fresh
  event slides in (breaking-news feel).

### Phase 3 — landing top-signals preview
- **`TopSignals.tsx`** — pulls tonight's REAL top-3 A-rated grades from
  `/api/snapshot/{mlb,nba,wnba}` as mini grade cards (archetype + grade + line) +
  the live `AccuracyBadge`. Self-hides off-hours. The product shown, not described.

### Founder pricing (the real cause of the "4 stripe failures")
`FOUNDER_CODE_EXPIRY` default was `2026-06-30` — lapsed as of the current date
(2026-07-10), silently disabling every founder code (and the ClaimMeter scarcity
pitch). Extended the default to `2026-12-31` (operators still override via env).
That restored founder pricing AND turned the 4 failing tests green.

### Honest scope (deferred — NOT built this session)
The prompt's Phases 4–8 (dashboard card redesign, scan reveal polish, Parlay Lab
derivatives-desk polish, nav/mobile/onboarding/settings/team-hub polish) are real
follow-on work. This session invested in the two TRANSFORMATIVE, differentiated
systems (real-time + self-learning) end-to-end with tests + the highest-leverage
first-visit surfaces (landing signals, dashboard accuracy). Live calibration
adjustment (spec 2.3, feeding outcomes back into grade confidence) is scaffolded
by the accuracy record but not yet wired into the engine.

## Session 54 (2026-06-19) — SHIPPED ✅ AUDIT CLEANUP

Backend 2246 → **2255 tests** (+9), 194 suites. Web build clean (exit 0).

### Phase 1 — name edge cases (BOTH playerName.js copies, kept identical)
- **Hyphens** stripped in `normalizeName` display+key (`.replace(/-/g,' ')`) so
  "Jung-hoo Lee" === "Jung Hoo Lee".
- **Middle single-letter tokens** stripped in `nameKey` (keep first + last) so
  "Josh H Smith" === "Josh Smith". Guarded: real middle names ("Juan Carlos
  Smith") and collapsed first initials ("JC Escarra") are untouched.
- **`richie: 'richard'`** added to NICKNAMES.

### Phase 2 — polish
- **Team Hub names normalized** at the source: `teamService.getTeamHub` now maps
  every roster player (MLB + snapshot-fallback) through `normalizeName().display`
  → "J.C. Escarra" renders as "JC Escarra", matching the dashboard.
- **Accent-keeping dedup** (`snapshotService`): when collapsing variant grades,
  the GRADE picked is still highest-confidence, but the DISPLAY now prefers the
  accented variant ("José" over "Jose") so prop rows match the pitcher line.
- **Parlay copy**: same-game (different-team) warning now names the game —
  "⚠ 2 legs from the same game (NYY @ BOS) — correlated".

## Session 53 (2026-06-19) — SHIPPED ✅ SOCIAL PREVIEW FIX

## Session 53 (2026-06-19) — SHIPPED ✅ SOCIAL PREVIEW FIX

Backend 2239 → **2246 tests** (+7), 193 suites. Web build clean (exit 0).

- **OG/Twitter copy de-jargoned** (`layout.tsx`): the openGraph description had
  "Bayesian intelligence / kill conditions"; the main description had "xG
  regression / penalty taker". Replaced with "Pre-graded player props with
  proprietary archetypes. Correlation-aware Parlay Lab. Real-time line movement
  tracking. Built in Detroit." Title → "VYNDR — The edge the books don't want you
  to have". NOTE: did NOT write "45 archetypes" (the spec said 45, but the codebase
  has 41 — used "proprietary archetypes" to stay accurate).
- **Dynamic OG image** (`app/opengraph-image.tsx` + `twitter-image.tsx` re-export):
  1200x630, #06060B bg, VYNDR wordmark (green R), "The books have every advantage.
  / We built this to give it back." + feature row. Node runtime (NOT edge — this
  is a self-hosted standalone build). Both routes prerender to a real PNG at build.
- The stale static `/og-image.png` reference was removed from metadata so the
  file-based convention owns the image (no duplicate/conflicting og:image tag).

## Session 52 (2026-06-19) — SHIPPED ✅ TEASER + INFRA VERIFICATION

Backend 2234 → **2239 tests** (+5), 192 suites. Web build clean (exit 0).

### Phase 1 — Push-to-Book teaser (feature NOT live; teaser only)
- `StatStrip`: a `BookItTeaser` ("BOOK IT ⟶", hover tooltip "Push-to-Book coming
  soon — connect your sportsbook") after the parlay "+" on every graded prop.
- `GradeResultCard`: a "PUSH-TO-BOOK · COMING SOON" footer section.

### Phase 2 — infrastructure verification
- `snapshotScheduler` now logs BOTH states: armed (`[snapshotScheduler] armed —
  SNAPSHOT_CRON=1, hours=…`) and disarmed (so container logs disambiguate
  off-vs-crashed). Test asserts the armed log.
- NEW `GET /api/internal/snapshot/status` (internal-key gated): `{ cron_armed,
  cron_hours_utc, last_snapshot:{sport:{updated_at,gradeCount,deltaCount}},
  redis_keys:{…:bool}, ticker_count }`. The single probe to verify the pipeline
  post-deploy.
- REDIS PERSISTENCE FINDING: the app uses `REDIS_URL` (ioredis) — AOF/RDB
  persistence is a server-side (Coolify Redis) config the app can't set/verify.
  If snapshot keys vanish on restart, enable persistence on the Redis instance.

### Phase 3 — delta pipeline (verified sound; no fix needed)
`runSnapshot` already reads `:latest` as prev → `computeLineDeltas(enriched,
prev.grades)` → writes old→`:previous`, new→`:latest`. So deltas populate on the
2nd+ run. Added an opt-in debug log (`SNAPSHOT_DEBUG=1`) + a trace test asserting
`:previous` is preserved verbatim and the delta math is correct.

## Session 51 (2026-06-19) — SHIPPED ✅ TEAM HUB

## Session 51 (2026-06-19) — SHIPPED ✅ TEAM HUB

Backend 2215 → **2234 tests** (+19), 190 suites. Web build clean (exit 0).
New routes: `/team/[abbr]`, `/api/team/[abbr]`.

### Phase 1 — team data API
- `mlbStatsAdapter` gained `getTeams()` / `resolveTeam(abbr)` (statsapi
  `/teams?sportId=1`, cached 24h, abbr→id) + `getTeamRoster(teamId)` (active
  roster, cached 6h).
- `src/services/teamService.js getTeamHub(sport, abbr)` assembles the hub:
  resolve team → roster → per-player season stats (bounded concurrency 8, reuses
  playerIntelService mappers) → archetype (from the snapshot grade, else
  classify) → tonight's graded props (from `grades:{sport}`). Whole result cached
  15 min. MLB = real; NBA/WNBA = a snapshot-built partial roster (graceful note).
- `GET /api/team/:abbr` (public, 404 on unknown MLB team) + Next proxy.

### Phase 2 — Team Hub page
`team/[abbr]/page.tsx` (server, `generateMetadata`) + `TeamHub.tsx` (client):
team header + sport badge, sort (archetype / graded / A–Z), archetype filter
chips, roster rows (archetype badge + player link + position + horizontal stats
+ graded props with grade badges + parlay "+"), "No active props" greyed state,
loading/error states.

### Phase 3 — game card team links + back nav
`vyndr/GameCard` team abbreviations are now `TeamLink`s → `/team/:abbr?sport=`
(green hover, stops propagation from the open-game handler). Team Hub has
"← Back to Slate".

## Session 50 (2026-06-19) — SHIPPED ✅ PARLAY LAB

## Session 50 (2026-06-19) — SHIPPED ✅ PARLAY LAB

Backend 2185 → **2215 tests** (+30), 187 suites. Web build clean (exit 0).

### Phase 1 — correlation-score model (parlayService.js, ADDED to S28 funcs)
Numeric, GAME-AWARE model: `correlationScore(l1,l2)` → 0.7 same-player/game /
0.4 same-team/game / 0.2 same-game-diff-team / 0.0 diff-game. `combinedGrade` =
leg-grade avg penalized by `avgCorrelation * 0.5`. `estimatedPayout` = product of
per-grade fair odds × (1 − avgCorrelation) discount. `correlationWarning` →
"⚠ N legs from {TEAM}…". `gradeParlay` bundles it all.

### Phase 2 — POST /api/parlay/grade
Returns `{ combined, correlation, payout, legs }` (2–6 legs, public/stateless).
The Next `/api/parlay/grade` proxy was forwarding to the wrong upstream
(`/api/scan/parlay`) — fixed to the new route.

### Phase 3 — ParlayContext extended
`ParlayLeg` gained team/game/archetype; MAX_LEGS now 6 with a tier-aware
`maxLegs` (set by the panel). Auto-grades the slip (debounced) via the endpoint
when legs ≥ 2 → live `combined`/`correlation`/`payout`. + `hasLeg`/`legKey`/`atCap`.

### Phase 4 — "+" buttons
`StatStrip` renders a "+"/"✓" per graded prop (toggles add/remove); `vyndr/GameCard`
wires it via `useParlay` (builds a leg with team + game id). `GradeResultCard`'s
existing "Add to Parlay" feeds the same context from the scan page.

### Phase 5 — ParlayPanel (replaces legacy ParlayTray in the layout)
Bottom slide-up: legs (archetype + grade + remove), correlation warning, combined
grade, est. payout, CLEAR ALL + a floating leg-count badge (bottom-right) when
closed. Tier-gated: free 2 legs (payout blurred → Desk upgrade), Analyst 4, Desk 6.

## Session 49 (2026-06-19) — SHIPPED ✅ ONBOARDING FLOW

## Session 49 (2026-06-19) — SHIPPED ✅ ONBOARDING FLOW

Backend 2156 → **2185 tests** (+29), 184 suites. Web build clean (exit 0).
New routes: `/onboarding`, `/api/preferences`.

### Phase 1 — name micro-fixes (closes the normalization arc)
`playerName.js` (both copies): collapse adjacent single-letter words
("J C Escarra" → "JC Escarra", display + key) + added `mickey: 'michael'`.

### Phases 2–5 — onboarding, end-to-end
- **Storage:** Supabase `user_metadata.preferences` — NO migration. Shape:
  `{ sports[], books[], weekly_limit, onboarding_complete }`.
- **API:** `src/routes/preferences.js` GET/POST (requireAuth; service-client
  admin getUserById/updateUserById; POST is a PARTIAL merge + sanitized) +
  `/api/preferences` Next proxy (forwards the bearer).
- **Page:** `web/src/app/onboarding/page.tsx` — 3 self-contained steps (sports
  [≥1 required] → books [skip] → weekly bankroll [presets + custom + skip]) →
  "SIGNAL ACTIVE / You're locked in" → POST `onboarding_complete:true` → 2s →
  `/dashboard`. Redirects to /login when unauthenticated.
- **Redirect:** the dashboard fetches `/api/preferences` (fresh — avoids stale
  session metadata); if `onboarding_complete !== true` AND the user is NEW
  (`created_at >= 2026-06-19 cutoff`), → `/onboarding`. Never fires while auth is
  loading (would bounce unauthenticated users). Existing users are exempt.
- **Personalization:** the Slate defaults its tab to `prefs.sports[0]`; preferred
  books are highlighted (green glow) in each game card's lines grid
  (`isPreferredBook` in `lib/books.js`, threaded dashboard → Slate → GameCard).
- **Settings:** a PREFERENCES section loads (GET) + edits + saves (POST) sports,
  books, and weekly limit.

## Session 48 (2026-06-19) — SHIPPED ✅ NORMALIZATION AT EVERY LAYER

## Session 48 (2026-06-19) — SHIPPED ✅ NORMALIZATION AT EVERY LAYER

The normalizer functions were correct (S47) but raw names still flowed through
paths that skipped them. Traced top-down, fixed each. Backend 2149 → **2156
tests** (+7), 181 suites. Web build clean (exit 0).

### The trace (3 leaking paths)
1. **Snapshot grades** stored RAW player names + no dedup → Explore/leaders/
   profile/GameCard-overlay all saw variants.
2. **Game-card strips** merged the player but pushed EVERY variant prop → "Ks 5.5
   AND Ks 3.5" duplicate rows.
3. **Scan player grid** (`tonightsPlayers`) grouped by raw `p.player` → variant tiles.

### Fixes
- **2a (source chokepoint):** `snapshotService.runSnapshot` now normalizes each
  grade's player to the de-dotted display AND dedupes to ONE grade per
  normalized player+stat (highest confidence) BEFORE writing `grades:{sport}` +
  `snapshot:{sport}:latest`. Every consumer now gets clean, merged names for free.
- **2b:** `buildPlayerStripsFromProps` dedupes a player's props by stat (prefers
  the graded over an awaiting row) → one row per stat.
- **2c:** scan `tonightsPlayers` groups by `nameKey`, displays `normalizeName().display`.
- **3 (profile usage/rest):** the "+0%"/"—" was the PLAYER PROFILE's `buildIntel`
  (separate from the grade card's `buildIntelFields`, which already works — the
  full feature merge carries ab_per_game/rest_days, NOT filtered by FEATURE_NAMES
  which is meta-only). `resolvePlayerStats` (MLB) now attaches real `usage`
  (AB/G) + `rest` (B2B/Xd) and `buildIntel` renders them; REST default is now
  "—" not "+0%".

## Session 47 (2026-06-19) — SHIPPED ✅ NAME NORM + INTEL + TICKER POLISH

## Session 47 (2026-06-19) — SHIPPED ✅ NAME NORM + INTEL + TICKER POLISH

Backend 2122 → **2149 tests** (+27), 179 suites. Web build clean (exit 0).

### Phase 1 — complete name normalization
`playerName.js` (both copies) gained: parenthetical-tag strip ("Jose Fermin (STL)"
→ "Jose Fermin"), a ~50-entry NICKNAMES table resolved in `nameKey` ("Matt"↔
"Matthew", "Mike"↔"Michael"), and the existing accent-fold now verified for
Iván/Ivan, José/Jose. The slate strip now DISPLAYS the normalized de-dotted name
(`buildPlayerStripsFromProps` uses `normalizeName().display`) — "A.J. Ewing" shows
as "AJ Ewing", not the raw PropLine string.

### Phase 2 — complete VYNDR INTELLIGENCE for MLB
The audit showed only Form. `mlbGameLogFeatures` now also derives `rest_days`
(days off between the two most recent game-log dates; 0 = B2B, matching the NBA
convention) and `ab_per_game` (the MLB "usage" equivalent). `buildIntelFields`
renders `usage` as "X AB/G", `rest` as "B2B"/"Xd rest", and a matchup grade from
`bvp_advantage` when no opp rank. So MLB grade cards now show Form + Usage + Rest
(+ Matchup when available).

### Phase 3 — ticker SCAN dedup
`pushTickerItems` keeps only the LATEST SCAN per sport (drops prior SCAN events
for any sport with a fresh scan; parses the sport from a `sport` field or the
text prefix for legacy items). MOVE/GRADE events preserved; cap stays 50.

### Phase 4 — archetype threshold
BOMBER's HR thresholds prorated for mid-season (`hr>=15` strong / `hr>=10`
moderate, was `>=20`/`>=15`), so June sluggers (Schwarber/Harper ~17-18 HR)
classify as BOMBER instead of FLEX/DRIVER. `computeLineDeltas` re-verified
structurally sound (deltas populate on the 2nd+ snapshot).

## Session 46 (2026-06-18) — SHIPPED ✅ P1 FIXES

## Session 46 (2026-06-18) — SHIPPED ✅ P1 FIXES

Backend 2100 → **2122 tests** (+22), 176 suites. Web build clean (exit 0).

### Phase 1 — grade card intel (ROOT CAUSE)
The STAT CONTEXT + VYNDR INTELLIGENCE sections were empty for MLB because
`gameLogService.getGameLogs` is NBA/WNBA-only (offline Python service) — MLB
props NEVER got `l5_avg`/`l20_avg`, so `buildIntelFields` always returned `{}`.
FIX: `featureCache.gameLogFeatures` now has an MLB branch that derives
l5/l10/l20 averages from `mlbStatsAdapter.getPlayerStats` (free statsapi.mlb.com)
via the pure `mlbGameLogFeatures` + an MLB stat_type→game-log-field map.
`buildIntelFields(features, opts)` also gained `playerStats`/`projection`
fallbacks so partial intel renders (Sessions 43/44 had the wiring; the engine
just never produced the values for MLB).

### Phase 2 — player name normalization
`src/utils/playerName.js` + `web/src/lib/playerName.js` (identical; cross-checked
by a test): `normalizeName(raw)` → `{ display, key }`. Strips periods, de-dots
suffixes, accent-folds the key. Applied in `snapshotService` (grouping/deltas),
`slateAdapter` (grade index + `buildPlayerStripsFromProps` merges variants,
displays the longest), and `playerIntelService.sanitizePlayerName`/`normName`.
"A.J. Ewing"/"AJ Ewing" and "Jazz Chisholm"/"Jazz Chisholm Jr." now merge.

### Phase 3 — MLB starting pitchers
The ESPN schedule lacks probable pitchers. NEW `GET /api/schedule/:sport/pitchers`
(MLB) → `probablePitchers` service wrapping `mlbStatsAdapter.getScheduleWithPitchers`
+ best-effort season ERA. The Slate fetches it, builds a team→pitcher map
(`slateAdapter.buildPitcherMap`/`pitchersForGameTeams`, matched by full name +
mascot), and attaches `pitchers` to MLB GameCardData. + Next proxy.

### Phase 4 — verify
`computeLineDeltas` confirmed structurally sound (S45 tests); `deltas: 0` in the
audit was just the first snapshot (no previous to diff). BACKEND_HANDOFF.md
updated.

## Session 45 (2026-06-18) — SHIPPED ✅ SNAPSHOT PIPELINE

## Session 45 (2026-06-18) — SHIPPED ✅ SNAPSHOT PIPELINE

The on-demand grade model is retired. Backend 2061 → **2100 tests** (+39), 173
suites. Web build clean (exit 0).

### Phase 1 — snapshotService (orchestration of existing services)
`src/services/snapshotService.js` `runSnapshot(sport)`: getOdds (PropLine
rotation) → gradeAndCacheSlate (captured via injected cacheSet) → classify each
player's archetype (resolvePlayerStats + archetypeService, pure math) → attach
`gradedAt {line, odds, timestamp}` (LOCKED) → compute line deltas vs the previous
snapshot → write `snapshot:{sport}:latest|previous` + `grades:{sport}` → emit
ticker events. `runAllSnapshots()` loops mlb/nba/wnba/soccer. Everything
injectable → fully unit-tested with zero network. Deltas: `toward` = market
confirming our side, `away` = opposing; noise filtered <0.5.

### Phase 2 — internal API + cron + ticker API
- `POST /api/internal/snapshot/:sport` + `/snapshot/all` (existing
  `requireInternalAuth`; `/all` registered first so it isn't captured as a sport).
- `GET /api/ticker` (public, cache-only, merges `TICKER_MANUAL` pins) + Next proxy.
- In-process cron `src/snapshotScheduler.js` (gated `SNAPSHOT_CRON=1`, UTC hours
  14,19,22,1,3 = 10AM/3PM/6PM/9PM/11PM ET), armed in server.js. No new dep —
  1-min unref'd interval, fires once per slot. Prefer external n8n cron hitting
  the internal endpoint for multi-replica deploys.

### Phase 3 — GameCard swap (THE product shift)
The live Slate now renders `vyndr/GameCard` (legacy kept for TYPES only). Reads
`GET /api/snapshot/:sport` (cache-only, public; falls back to `grades:{sport}`),
overlays the locked grades onto each game's odds-derived props via
`slateAdapter.buildPlayerStripsFromProps` → player name ONCE + archetype badge +
locked grade + "Graded Xh ago at -115 · Current 2.5 · ▲ TOWARD +1.0" line delta.
Ungraded props → "Awaiting next scan" (NO Read button). The on-demand onGrade
flow was deleted.

### Phase 4 — live ticker
`vyndr/Ticker` now polls `/api/ticker` every 30s (graceful: keeps the passed
hardcoded items as initial/fallback, never blanks). Tag colors: A+/A/SCAN green,
MOVE/CASCADE amber, ALERT white.

### Phase 5 — NBA/WNBA ESPN fallback
`espnStatsAdapter.getSeasonAverages(name, sport)` — free public ESPN stats,
DEFENSIVE (`parseAthleteStats` returns null on any unrecognized shape → caller
degrades to found:false; never a wrong-but-confident number). Wired as the
NBA/WNBA fallback in `resolvePlayerStats` after the offline Python service. Note:
the live ESPN athlete-stats shape may need tuning against production — the parser
is tolerant and tested against a representative payload.

### Env vars (set in Coolify)
- `PROPLINE_API_KEY_1/2/3` — PropLine props rotation (snapshot odds source).
- `VYNDR_INTERNAL_KEY` — the internal-auth secret (header `x-internal-key`) for
  the snapshot trigger. (This is the existing key, NOT a new INTERNAL_AUTH_TOKEN.)
- `SNAPSHOT_CRON=1` — arm the in-process scheduler (omit if using n8n).
- `TICKER_MANUAL` — JSON array of editorial pins, e.g.
  `[{"tag":"ALERT","text":"VYNDR 2.0 is live."}]`.

## Session 44 (2026-06-18) — SHIPPED ✅ MAKE IT VISIBLE

## Session 44 (2026-06-18) — SHIPPED ✅ MAKE IT VISIBLE

Wired existing backend work into the pages users see + renamed archetypes to
VYNDR Originals. Backend 2045 → **2061 tests** (+16), 167 suites. Web build clean
(exit 0). `BACKEND_HANDOFF.md` added as the canonical data contract.

### VYNDR Original archetype rename (proprietary names)
All 41 archetypes renamed in `archetypeService.js` + `lib/archetypes.js` +
`ArchetypeBadge`, each keeping `legacyName`/`legacy` (never displayed; resolves
for stale data). NBA: TORCH, CONDUCTOR, FORTRESS, ARTILLERY, SURGE, DUAL THREAT,
CONNECTOR, FASTBREAK, PAINT BOSS, LOCKDOWN, SWITCHBOARD, ARCHITECT, PISTON,
SENTINEL, IGNITER. WNBA-unique: DISTRIBUTOR, SHIELD, RANGE, SPARK, ANCHOR. MLB:
BOMBER, BRUSH, DRIVER, ALPHA, WHIFF, GHOST, HYBRID, FLEX, WORKHORSE, CATALYST,
MIRROR, HAMMER, SINKER, BRIDGE, SWITCH. Soccer: FINISHER, MAESTRO, TOWER, MOTOR,
BLADE, WALL. **MLB note:** the old taxonomy had two power hitters (POWER
PULL/POWER SLUGGER) but the new set has one power name (BOMBER), so BOMBER now
fires for any high-HR bat (Judge → BOMBER per the audit checklist) and the freed
slot became a real WHIFF strikeout-artist pitcher (improves pitcher coverage).
`getArchetype`/`archetypeInfo` resolve legacy names → VYNDR Originals.

### Phase 2 — grade-card intel now populates (the real bug)
The chain engine→tierGating→/api/scan proxy already PRESERVED the intel fields
(all spread `...result`/`...data`). The ONE broken link: `scan/page.tsx` called
`mapScanToGradeResult` with a hardcoded field subset and DROPPED season_avg/
form/usage/matchup_grade/etc. Now forwards them (+ extended `ScanResponse`), so
STAT CONTEXT + VYNDR INTELLIGENCE sections light up on a real MLB grade.

### Phase 3 — stale-game filtering
`slateAdapter.isRelevantGame(game, now)`: upcoming/live always show; a COMPLETED
game is dropped once >24h old (no more 5-day-old FINALs). Applied in `Slate`'s
`filteredGames`. Schedule TTL was already 60s (≤30min) — no change.

### Phase 4 — landing copy
`Features.tsx` rewritten: no more "Point-biserial", "Zone 14", "ABS
intelligence", "Auto-calibrating", "Phi-coefficient". User-facing benefit copy
(Player DNA archetypes / Self-improving model / Lineup intel before tip-off /
Deep pitcher-batter matchups).

### Phase 5 — depth chart proxies (404 fix)
Added the missing Next proxies `/api/stats/lineup/[team]`, `/depth/[team]`,
`/cascade/[player]` → return JSON, not 404.

### Phase 1 — GameCard swap DEFERRED (decision: Kev)
The live Slate keeps the legacy "Read"/on-demand grade card as a **temporary
bridge**. The vyndr/GameCard swap lands WITH the snapshot pipeline (next
session): the on-demand "Read" model is being retired for a pre-graded snapshot
model (full slate graded at scheduled intervals, grades locked to the line), and
the new card is designed for that. Swapping now would remove grading + show blank
cards (grades cache unpopulated). BookChip brand colors already render in the
legacy card (S43).

## Session 43 (2026-06-18) — SHIPPED ✅ DATA PIPELINE + AUDIT FIXES

## Session 43 (2026-06-18) — SHIPPED ✅ DATA PIPELINE + AUDIT FIXES

Post-S42 Chrome audit: architecture renders but no real data flowed (every
player `found:false`, leaders empty, grade intel hidden) + a P0 dropdown bug.
Backend 2011 → **2045 tests** (+34), 163 suites. Web build clean (exit 0).

### Phase 1 — P0 bug fixes
- **Avatar/More dropdown z-index** — the `<nav>` has `backdrop-filter` (a
  stacking context); `<Ticker>` + `<HeartbeatBar>` render after it as siblings
  and painted OVER the dropdowns (which overflow below the 60px bar), eating
  clicks. Fix: `position:relative; zIndex:2` on the nav floats it (and its
  menus) above those bars; menus also carry `zIndex:100`. Avatar "Settings" →
  `/settings` (was `/settings/security`). Explore was already in MORE (S42) —
  the audit "missing" was a deploy cache.

### Phase 2 — real player stats
- **`mlbStatsAdapter`** gained `searchPlayer(name)` (season player-list lookup,
  cached 24h) + `getPlayerStats(name)` (resolve id → season + game log, picks
  pitching/hitting by position). The adapter only had id-keyed methods before.
- **`playerIntelService.resolvePlayerStats(name, sport)`** normalizes the raw
  MLB stat object → classifier input + display season rows + last-10 log.
  `getPlayerIntel` now classifies the archetype from REAL stats and returns
  `found:true` with real season data. Aaron Judge → POWER PULL, not the
  empty-stats fallback. NBA/WNBA path wired to `nbaStatsClient` (degrades
  quietly — the Python nba_api service is usually offline in prod). All
  adapters injectable for tests; everything still degrades gracefully.
- **Leaders**: `/api/stats/leaders` + the explore page already share the
  `grades:{sport}` cache source — no mismatch to fix. Emptiness is data
  population (the slate must be graded first); the snapshot pipeline (Session
  44) keeps it warm.

### Phase 3 — game card enhancements
- `slateAdapter` gained `groupPropsByPlayer` (→ `playerStrips`, name once) +
  `mapPitchers` (MLB probables → GameCard `pitchers`); both folded into
  `mapScheduleToGameCards` output (vyndr/GameCard consumes them; legacy ignores
  the extras). Legacy `GameCard` line grid now renders `BookChip` (brand
  colors) instead of plain grey book text (the audit's complaint).

### Phase 4 — grade card intelligence
- `analyzeViaEngine1` attaches stat-context + VYNDR-intelligence fields
  (`season_avg`/`last10_avg`/`form`/`usage`/`matchup_grade`/`rest`) computed
  from the EXISTING feature vector — zero extra I/O. `gradeAdapter` maps them in,
  so the card's STAT CONTEXT + VYNDR INTELLIGENCE sections light up. Archetype
  is intentionally NOT set here (the per-prop feature vector lacks a multi-stat
  season line; the archetype strip stays hidden until Session 44 feeds it).

### Phase 5 — depth chart foundation
- **`src/services/depthChartService.js`**: `getLineup` (MLB probable starter
  from the schedule), `getDepthChart` (positions from an injected roster),
  `getCascadeProjection` (usage redistribution weighted by archetype — sponges
  heaviest). All graceful + injectable. Endpoints: `/api/stats/lineup/:team`,
  `/depth/:team`, `/cascade/:player`. (Next proxies + UI = Session 45.)

### Phase 6 — mobile + cosmetics
- Player-profile hero name was clipping ("Wembanyam") at 390px — added
  `overflow-wrap:anywhere` + a mobile rule (`.player-hero-name` 24px). Font CDN
  already gone since S41 (next/font).

### Deferred (honest scope)
- Full live-slate swap to vyndr/GameCard (needs inline grading ported) — the
  data layer is now ready (`playerStrips`/`pitchers`).
- Per-player archetype badges on slate cards + grade-card archetype strip — need
  per-player season lines at grade time (Session 44 snapshot pipeline).
- Depth chart UI + lineup/minutes projections (Session 45).

## Session 42 (2026-06-18) — SHIPPED ✅ PLAYER INTELLIGENCE SYSTEM

## Session 42 (2026-06-18) — SHIPPED ✅ PLAYER INTELLIGENCE SYSTEM

Built the full Player Intelligence design bundle (10 sections; the 6 spec items
+ extras). Backend 1940 → **2011 tests** (+71), 157 suites. Web build clean
(exit 0). Both gates green.

### What shipped (by design section)
1. **Archetype system** — `src/services/archetypeService.js`: 41 archetypes
   (15 NBA + 5 WNBA-unique + 15 MLB + 6 soccer), each with tag/color/glyph/
   description/propDNA/education. `classify(sport, stats)` returns PRIMARY +
   optional SECONDARY + a normalized `blend`. Visual map mirrored in
   `web/src/lib/archetypes.js` (CommonJS, colors verified == backend).
   Components: `ArchetypeBadge` (full/ghost/tint + glyphs), `ArchetypeBlend`
   (the production-DNA bar).
2. **StatStrip** — `components/vyndr/StatStrip.tsx`, compact + expanded. The
   player name appears ONCE; stats flow horizontally (JetBrains Mono); props
   inline with GradeBadge; `onPlayerClick` → profile.
3. **Stats API + Player Profile** — extended `src/routes/stats.js` with
   `/player/:name`, `/leaders`, `/game/:id` (rate-limited 60/min). Aggregation
   in `src/services/playerIntelService.js` (sanitizes the name param; reads
   grades:{sport} cache for props; graceful on cold caches). Page:
   `app/player/[name]/page.tsx` — all 9 design sections (hero+DNA blend, injury,
   prop DNA, VYNDR intelligence, active props, season, last 10, splits, grade
   history). Next proxies under `app/api/stats/player|leaders`.
4. **Enhanced game cards + Grade Result** — `vyndr/GameCard` gained optional
   MLB starting pitchers + player-grouped `playerStrips` (StatStrip, name once);
   `GradeResultCard` gained archetype strip + STAT CONTEXT + VYNDR INTELLIGENCE
   (all optional/self-hiding; populated by `gradeAdapter.buildIntelFields`).
   Header player name now links to the profile.
5. **Settings page** — `app/settings/page.tsx` REPLACES the S41 redirect:
   account (tier from useAuth), subscription, notifications, display (→ Prefs
   modal via `window.__prefs`), responsible play, danger zone (delete button
   gated on typing DELETE exactly). LINKS to `/settings/security` — does NOT
   replace the real MFA page. + `BookChip` component (`lib/books.js`).
6. **Stats Explorer (bonus, design §07)** — `app/explore/page.tsx`: tonight's
   league leaderboard from the real `/api/stats/leaders`, sport tabs, search,
   rows → player profile. Added to the Nav MORE menu (Explore + Settings→/settings).

### Player-name links wired
Game cards, Grade Result header, Stats Explorer rows, profile active props — all
route to `/player/:name?sport=` via `lib/playerHref.js`.

### Deferred (design sections present but NOT built this session)
Team Hub (§09), Offseason Intel (§08), and the Slate redesign (§10), plus the
Stats Explorer sub-panels (hit-rate trends, head-to-head, market-vs-VYNDR,
matchup ratings). These need historical / projection / depth-chart data
pipelines that don't exist yet — they belong with the Session-43 snapshot
pipeline. The archetype + leaders + profile foundations they'd build on are now
in place.

## Session 41 (2026-06-17) — SHIPPED ✅ P0 AUDIT FIXES

The Chrome audit's P0 list only. No features. Backend 1907 → **1940 tests**

## Session 41 (2026-06-17) — SHIPPED ✅ P0 AUDIT FIXES

The Chrome audit's P0 list only. No features. Backend 1907 → **1940 tests**
(+33), 149 suites, all green. Web build clean (compiled successfully, exit 0).

### Fixes
1. **MLB stat_type gate (BACKEND)** — the Scan frontend sends MLB IDs (`hits`,
   `strikeouts`, `total_bases`, `rbi`, `home_runs`, `earned_runs`, `hits_allowed`,
   `innings_pitched`, `runs`, `walks`, `stolen_bases`) but `VALID_STAT_TYPES` in
   `src/routes/analyze.js` + `src/routes/scan.js` only whitelisted the NBA/soccer
   set, so every MLB scan 400'd. Added the MLB set to both gates, mirroring the
   already-correct `python/utils/validation.py` `VALID_STAT_TYPES.mlb`. The live
   grade path is the generic engine1 feature pipeline (note: `mlbGrader.js` is
   dead code — required nowhere), which keys off these exact stat names.
2. **/settings → /profile, /report → /blog** — new server-component `redirect()`
   pages (`app/settings/page.tsx`, `app/report/page.tsx`). `/profile` is the
   canonical account surface; `/blog` is where "The Report" lives.
3. **Profile tier mismatch** — `app/profile/page.tsx` showed "Free" (from the
   `/api/user/profile` fetch) while the nav showed the real tier (from
   `useAuth().tier`). Profile now derives the displayed tier from
   `useAuth().tier` (`authTier || profile.tier || 'free'`); the fetch still
   supplies scan_count/subscription_*/founder.
4. **Self-hosted fonts** — replaced the runtime `fonts.googleapis.com`
   stylesheet `<link>` (503 in prod, ~4s page load) with `next/font/google`:
   Inter→`--font-sans`, JetBrains_Mono→`--font-mono`, IBM_Plex_Mono→`--font-ibm`,
   variables set on `<html>`. globals.css `:root` maps `--sans`/`--mono`/
   `--ibm-mono` onto them. Because next/font obfuscates family names, literal
   `'JetBrains Mono'`/`'IBM Plex Mono'` references in CSS + inline component
   styles were rewired to the variables (Hero, upgrade/desk, NotificationBell,
   responsible-gambling, globals.css wordmark/.lines).

### Deviations from the spec (flagged)
- **Did NOT overwrite `/settings/security`.** The spec said redirect it to
  `/profile` too, but that route is a working MFA enrollment flow — clobbering it
  would be a security-feature regression. Left intact; only the bare `/settings`
  404 was fixed.
- **`/report` link doesn't exist in current code** — Nav's "The Report" already
  points to `/blog`. The redirect is harmless defensive coverage (PWA shortcut /
  external / stale share links).
- **ShareCard canvas** still uses literal `"JetBrains Mono"`/`"Instrument Sans"`
  (canvas `ctx.font` can't read CSS vars). Out of P0 scope; pre-existing.

## Session 39 (2026-06-16) — SHIPPED ✅ DESIGN CONVERSION COMPLETE

Phase H: the QA pass against the §13 parity checklist. Verify → fix → lock.
Frontend-only; ZERO backend changes. Backend 1890 → **1907 tests** (+17), 146
suites, **stable across 3 consecutive full-suite runs** (the S38 flaky test is
fixed). Web build clean (compiled successfully, exit 0).

This completes the 7-session VYNDR 2.0 conversion (Sessions 33–39): tokens →
components → shell → screens → mobile → systems → QA.

### §13 AUTOMATED CHECKLIST — RESULTS
- **QA.1 Token resolution** — FIXED. `#00ffb8` (= the A+ token) → `var(--g-ap)`
  in ProcessingGrade (7 sites); `game/[id]` sport literals (`#E94B3C/#1E90FF/
  #FFB347`) → `var(--s-nba/mlb/wnba)`. Remaining hex are INTENTIONAL +
  documented: `var(--token, #fallback)` belt-and-suspenders (soccer/offline/
  admin), Next metadata `themeColor` (can't be a var), and bespoke intel-surface
  / red-tint text shades (`#e8fff4`,`#bdf5e2`,`#ff8a8a`,`#ff8b7a`,`#ffb0a4`,
  `#ffd9a8`,`#04140f`) ported verbatim from the prototype — no token equivalent;
  retokenizing would visibly deviate from the design.
- **QA.2 Typography** — PASS. Data rows/chips use `var(--mono)`; the GradeResult
  hero LETTER is `var(--sans)` (display) faithful to the prototype's grade-card.
- **QA.3 Grade prominence** — PASS. Hero 92–116px (80px mobile), GradeBadge hero=100.
- **QA.4 Best/worst lines** — PASS. Legacy GameCard (live slate) + vyndr/GameCard
  tint best green (`rgba(0,212,160,.13)` + green left border) / worst red.
- **QA.5 Wordmark everywhere** — PASS. Nav, Footer, login, about, 404 (+ social cards).
- **QA.6 Glitch discipline** — PASS. ZERO glitch classes in GradeResultCard /
  GameCard(s) / ProcessingGrade. Glitch stays on chrome only.
- **QA.7 Heartbeat/ticker/live counters** — PASS (Phase G; under the nav).
- **QA.8 Scan reveal** — PASS. ProcessingGrade factor-ignite → CRT-sweep → card.
- **QA.9 Command palette (⌘K)** — DEFERRED (documented). Nav `›` Query links to
  /scan; a true ⌘K palette was never in scope for 33–39.
- **QA.10 Parlay correlation** — PASS (Phase G `lib/parlayMath.js`, tested).
- **QA.11 Mobile parity** — PASS. 5-tab bar (Slate/Terminal/Scan/Ledger/More).
- **QA.12 Auth gate / deep-links / paywall** — PASS (AuthGate, HashRedirect, read-meter→paywall).
- **QA.13 i18n / odds** — PASS. `fmtOdds` converts ML; totals pass through (tested).
- **QA.14 Accessibility** — PASS. Prefs modal sets `<html data-*>`, persists.
- **QA.15 PWA** — PASS (S27 SW + S37 manifest/shortcuts/viewport-fit). Not touched.
- **QA.16 No dead buttons** — PASS. Zero `onClick={}` (asserted by a tree-walk test).
- **QA.17 No AI slop** — MANUAL (flagged for Kev's browser review — see below).
- **QA.18 Auth-gate integration** — PASS. Gates via lib/routes → `/login?next=`.

### De-flake (completion-quality)
The S38-flagged flaky test (`soccerFeatureExtractorCascade › nextMatch cascade`)
intermittently hit Jest's 5s default under full-suite concurrency (the extractor
falls through to live adapters on a cache miss). Added `jest.setTimeout(20000)`
to that test file — same fix family as S32's CPU-bound pipeline test. Test-only,
no service change. Verified: 3 consecutive clean full-suite runs (1907/1907).

### Files created
- `tests/unit/vyndrParityQA.test.js` (17 tests locking QA.1/4/5/6/11/16/18 —
  glitch-free data, token resolution, best-line tint, wordmark presence, 5 tabs,
  no dead buttons, auth-gate list)

### Files modified
- `web/src/components/vyndr/ProcessingGrade.tsx` (#00ffb8 → --g-ap)
- `web/src/app/game/[id]/page.tsx` (sport literals → tokens)
- `tests/unit/soccerFeatureExtractorCascade.test.js` (de-flake timeout)

### ⚠️ MANUAL CHECKS for Kev (browser, post-deploy)
- [ ] No AI slop (gradient bg / rounded-pill SaaS cards / stray emoji / exposed-
      algorithm copy). NOTE: 🔥 STREAKS + ◎ scan glyph are deliberate data markers.
- [ ] North-star energy — every page belongs with the 404.
- [ ] Auth gate end-to-end: incognito → /ledger → /login?next=/ledger → sign in → /ledger.
- [ ] Mobile: tab bar native feel, More sheet slide, touch targets.
- [ ] Scan grade reveal plays; ticker scrolls; best/worst line tints; PWA installs.
- [ ] Still-open operator item (since S31): rotate the leaked GitHub PAT in the
      `origin` remote URL and scrub it from `.git/config`.

## Session 38 (2026-06-16) — SHIPPED

Phase G: the systems that make the design alive. All 5 wired (minimal-wire path
where a full path risked regressions, per the scope guidance). Frontend-only;
ZERO backend changes. Backend 1872 → **1890 tests** (+18), 146 suites, zero
regressions. Web build clean (exit 0).

### Testable CommonJS lib modules (the reliable surface)
- **`lib/parlayMath.js`** (§12) — `getCorrelation` (same player 0.62 / same team
  0.34 / same league 0.06 / cross-sport 0), `parlayGrade` (averages leg grades +
  bumps the slip down a tier when any pair correlates >0.4), `GRADE_ODDS`,
  amToDec/decToAm, `combinedDecimal`/`combinedAmerican`, `correlationPairs`.
  Frontend model that powers the Parlay Lab matrix; the BACKEND parlayService
  (Session 28) still owns server combined odds + suggestions.
- **`lib/oddsFormat.js`** (§9) — `fmtOdds(value, format)` (american/decimal/
  fractional/implied), `REGIONS`/`CURRENCIES`/`regionPreset`. **Deliberately
  SAFER than the prototype's `parseAm`**, whose regex accepted decimals and
  would mis-convert O/U totals (228.5 → fake implied %). Our `parseMoneyline`
  only treats explicitly-signed integer STRINGS (+150/-110) and integer NUMBERS
  (the grade→odds map) as odds; totals/lines/spreads ("228.5","229","-7.5") pass
  through unchanged. (Honest spec-over-prototype correction, like the S32 NFL keys.)
- **`lib/prefs.js`** (§10) — `applyPrefs` sets `<html data-motion|contrast|text|
  cb|font>` (the CSS layer from Session 33 keys off these), `loadPrefs`/
  `savePrefs` to `localStorage('vyndr_prefs')`. Injectable element + storage →
  fully unit-tested.
- **`lib/liveTick.js`** (§8) — single tick store, fan-out subscribers. Does NOT
  auto-start on import (SSR/test-safe); `start()` begins the 1s interval (unref'd),
  `tick()` advances + emits a FRESH state object (so React re-renders); `reset()`
  for tests.
- **`lib/checkout.js`** (§12) — `checkoutUrl(plan)` → `/api/checkout?tier=…`.

### React glue + wiring
- **`components/vyndr/LiveLayer.tsx`** — `useLive()` hook (starts the shared tick,
  one interval many subscribers), `LiveNumber` (count-tick pop on change),
  `HeartbeatBar` (scrolling EKG + SIGNAL LIVE + live graded count + breathing
  neural % + sync clock). Mounted under the Ticker in the Nav.
- **`components/vyndr/GlobalHosts.tsx`** — mounted once in layout. On mount:
  applies stored prefs to `<html>`, registers `window.__prefs` / `__goPaywall` /
  `__checkout`. Hosts the **Preferences modal** (region→odds+currency cascade,
  odds format, text size, reduce-motion, high-contrast, colorblind, readable
  font — persisted) and the **Paywall modal** (Analyst/Desk tiers → `__checkout`).
- **Nav** — mounts HeartbeatBar; added a globe **prefs trigger** (`__prefs`); the
  free-tier read meter is now a button → `__goPaywall` (the §12 live paywall
  trigger). Header is now nav 60 + ticker 32 + heartbeat 30 → layout `main`
  paddingTop 96 → **124**; Slate sticky header `top` 64 → 122 to match.

### Animations gated behind reduced-motion
The living-layer classes (ekg-track, live-dot, count-tick, etc.) are already in
the Session-33 reduced-motion kill list (both `prefers-reduced-motion` and
`html[data-motion="reduced"]`), which the prefs toggle now sets. The tick still
fires (data updates); only the animation is killed.

### Files created
- `web/src/lib/{parlayMath,oddsFormat,prefs,liveTick,checkout}.js`
- `web/src/components/vyndr/{LiveLayer,GlobalHosts}.tsx`
- `tests/unit/vyndrSystems.test.js` (18 tests: correlation tiers + grade penalty
  + odds combine, odds formats + totals-pass-through + region presets, applyPrefs
  + storage round-trip, tick fan-out/increment, checkout URL, React-glue wiring)

### Files modified
- `web/src/app/layout.tsx` (GlobalHosts mount + paddingTop), `web/src/components/
  Nav.tsx` (HeartbeatBar + prefs + paywall meter), `web/src/components/Slate.tsx`
  (sticky top)

### Notes / gotchas
- BUILD GOTCHA (caught + fixed): a `useEffect` returning `liveTick.subscribe(...)`
  directly failed type-check — `Set.delete` returns boolean, not a valid effect
  cleanup. Wrapped in `() => { unsub(); }`.
- FLAKY (pre-existing, NOT this session): one full-suite run showed 1 failing
  backend test (computeFeatures/oddsService async-timing warnings); it passed on
  re-run (1890/1890 twice). Unrelated to these frontend changes — flagged for a
  future stabilization pass.
- Did NOT touch the PWA/service worker (Session 27/37 own it) per the no-overlap rule.

## Session 37 (2026-06-16) — SHIPPED

## Session 37 (2026-06-16) — SHIPPED

Phase F: mobile parity — the mobile build is the PWA we launch first. Converted
the bottom nav to the §6 5-tab spec, added the More bottom sheet, mobile CSS,
and PWA polish. Frontend-only; ZERO backend changes. Backend 1853 → **1872
tests** (+19), 145 suites, zero regressions. Web build clean (exit 0).

### F.2/F.3 — Bottom tab bar + More sheet (`components/BottomTabBar.tsx` rewritten)
- 5 tabs per §6: **Slate · Terminal · Scan · Ledger · More**. **Scan is the
  prominent raised action** — a 46px grade-green circle lifted above the bar
  (it's the core action). Active = `--g-a`, inactive = `--text-2`, 9px mono
  labels, 64px bar, `env(safe-area-inset-bottom)`, ≥44px touch targets.
- **More** opens an integrated bottom sheet: `fade-in` backdrop (dismiss on tap)
  + `sheet-up` scanlines panel, handle pill, MORE title + × close, 10 secondary
  routes (Compare/Tracker/Report/Invite/Pricing/Account/Settings/Help/About/
  Responsible) as 48px mono rows. Dismisses on item nav / backdrop / ×.
- BEHAVIOR CHANGE: the bar now shows for ANON users too (previously hidden when
  signed-out). Slate/Terminal/Scan are open routes and this is the only mobile
  nav; gated taps (Ledger/Account) bounce through the Session-34 AuthGate. Still
  hidden on auth flows + landing (`HIDE_ON`). Dropped the old Parlay tab (the
  global ParlayTray keeps its own trigger).

### F.4 — Mobile header
- Retired the Nav hamburger on mobile (`display:none`) — the tab bar + More sheet
  own mobile nav now. The Nav already hid desktop links <768px, so the mobile
  header is just wordmark + bell + read-meter + avatar. Mobile panel is now dead
  code (harmless).

### F.5 — Mobile CSS (`globals.css`)
- `.mobile-tab-bar` hidden ≥768px; `main` bottom-padded `calc(84px + safe-area)`
  <768px so content clears the bar; `.grade-hero` → 80px <640px (GradeResultCard
  letter tagged `grade-hero`); `.terminal-grid` stacks to 1fr ≤768px (Terminal
  grid tagged); `.game-lines-grid` horizontal-scroll + sticky `.team-col` <640px.

### F.6 — PWA polish
- `manifest.json`: added **shortcuts** (Slate/Scan/Terminal deep-links), categories
  → `["sports","finance","productivity"]`. Already standalone + theme/bg `#06060B`.
- `layout.tsx` viewport: added `viewportFit: 'cover'` (notch/home-indicator) so
  the tab bar's safe-area padding has room. apple-mobile-web-app-* already set
  via metadata.appleWebApp (Session 27).

### Files created
- `tests/unit/vyndrMobile.test.js` (19 tests: 5 tabs, prominent Scan, safe area,
  More sheet items/backdrop/44px, mobile CSS rules, Nav hamburger hidden,
  grade-hero hook, manifest standalone/shortcuts/categories, viewport-fit)

### Files modified
- `web/src/components/BottomTabBar.tsx` (full rewrite), `web/src/components/Nav.tsx`
  (hamburger hidden), `web/src/app/globals.css` (mobile section),
  `web/src/components/vyndr/GradeResultCard.tsx` (grade-hero class),
  `web/src/app/terminal/page.tsx` (terminal-grid class),
  `web/public/manifest.json` (shortcuts/categories), `web/src/app/layout.tsx`
  (viewportFit)

### Gotcha logged
- `as const` on the TABS array made each entry a distinct literal type, so
  `isSheet`/`primary`/`href` failed type-check on tabs lacking them. Fixed with a
  shared `TabDef` interface. (The build worker exits code 1 on type errors; a
  piped `| tail` masked it — always check the build exit code, not just the tail.)

### Deferred (Sessions 38+)
- Living-layer ticker/heartbeat data, i18n, a11y toggle wiring, SW, paywall,
  parlay math = Phase G (Session 38). §13 QA = Session 39.

## Session 36 (2026-06-16) — SHIPPED

## Session 36 (2026-06-16) — SHIPPED

Phase E of the VYNDR 2.0 conversion + Session 35's #1 deferred item (the
dashboard line upgrade). Frontend-only; ZERO backend changes. Backend 1839 →
**1853 tests** (+14), 144 suites, zero regressions. Web build clean (exit 0).

### E.1 — Dashboard GameCard (Session 35's #1 deferred) — DELIVERED via reskin
- KEY DECISION: the live Slate's legacy `GameCard` carries **inline per-prop
  grading** (PlayerCard/PropRow → onGrade/gradedProps). The Session-35
  display-only `vyndr/GameCard` has no grading, so a wholesale swap would
  DELETE the slate's core interaction. Instead, **reskinned the legacy GameCard's
  game-lines grid** with the Bloomberg best/worst pattern + SportBadge +
  SectionHead, keeping grading 100% intact — the #1 visual win without the
  regression.
- `web/src/lib/slateAdapter.js` (CommonJS, unit-tested): `parseAmericanOdds`
  (American → decimal payout), `detectBestLines(books)` (marks best/worst ML per
  side, only when ≥2 books disagree), `mapScheduleToGameCards(schedule,
  gamelines, streaks, grades)` (the §7 contract mapper, for the future full
  swap). GameCard now renders the lines grid via `detectBestLines`: best =
  green tint + green left border, worst = subtle red. Dropped the emoji marker
  for SportBadge.

### E.3 — Four stubs → real pages (zero regression risk)
- `compare` — head-to-head: two TerminalInputs, side-by-side stat table
  (winner-highlighted), intel-surface VYNDR VERDICT. Sample data.
- `invite` — referral: progress 0/3, mono referral link + copy button, share
  CTA. Code derived from the session email.
- `help` — searchable FAQ: TerminalInput filter + expandable Card Q&A by
  category + support mailto.
- `about` — brand page in system voice (glitch Wordmark, "give it back",
  Detroit signature). Server component.

### E.2 — Reskins (logic preserved)
- `login` — scanlines background, new `.wm` Wordmark (beta), system voice
  ("ACCESS THE SIGNAL"), Level-1 card. ALL auth logic (form, OAuth, `next`
  redirect) untouched.
- `pricing` — mounted `ClaimMeter` under the grid; removed the now-doubled
  `paddingTop` (layout already offsets 96 since Session 34).
- `account` is a redirect to `/profile` — left as-is (canonical surface).

### Files created
- `web/src/lib/slateAdapter.js`
- `tests/unit/vyndrPhaseE.test.js` (18 tests: adapter odds/best-line/mapping
  logic, GameCard reskin, the 4 real pages, login/pricing reskins)

### Files modified
- `web/src/components/GameCard.tsx` (Bloomberg lines + SportBadge/SectionHead)
- `web/src/app/{compare,invite,help,about,login,pricing}/page.tsx`
- `tests/unit/vyndrAppShell.test.js` (only /notifications remains a stub)

### Deferred (Sessions 37+) — honest scope
- The FULL GameCard swap (replacing legacy GameCard with vyndr/GameCard) needs
  inline grading ported into the new component first — bigger than a reskin;
  the slateAdapter + new GameCard are both ready for it. Reskinned instead this
  session to avoid deleting grading.
- Profile/settings/blog/game-detail/responsible reskins + scan-input
  TerminalInput polish: light or deferred (tokens already mostly resolve there;
  prioritized dashboard + paid-user-visible + new pages per the impact order).
  Settings destructive-action confirmations (type-DELETE) are Phase G utility
  flows.

## Session 35 (2026-06-16) — SHIPPED

## Session 35 (2026-06-16) — SHIPPED

Phase D of the VYNDR 2.0 conversion: the screens users touch. Frontend-only;
ZERO backend changes. Backend 1818 → **1839 tests** (+21), 143 suites, zero
regressions. Web build clean (exit 0, 36 routes).

### Strategy (5 screens, time-boxed → prioritized + honest scoping)
Built the high-value NEW components fully + wired the core moment, with
deliberate restraint where ripping out a working flow would regress
monetization or features (paywall polish is Phase G, Session 38).

### D.1 — Grade Result Card (the product's core moment) ✅ full + wired
- `components/vyndr/GradeResultCard.tsx` — faithful port: header, intel-surface
  grade hero (92–116px grade letter, grade-reveal + crt-sweep-local), confidence
  strip, phosphor-confirmed pill, MODEL/LINE/EDGE row, signal breakdown, amber
  kill-conditions, best-book strip (green tint + green left border), Desk alt
  ladder, action row. **Every section self-hides when its data is empty.**
  Callback props (onShare/onAddToParlay/onReadAnother) instead of window.__.
- `components/vyndr/ProcessingGrade.tsx` — the "weighing factors" reveal:
  factor-ignite sequence + proc-scan bar + % rail + minimal inline neural SVG
  (brain-node/brain-link), then reveals the card. Full NeuralBrain = Session 38.
- `lib/gradeAdapter.js` (CommonJS, unit-tested) — maps our engine output
  (`/api/scan` ScanResponse + GradeCard props) → the §7 GradeResultCard contract:
  direction→side, humanized stat, computed % edge (projection vs line),
  phosphor-confirmed heuristic, factor→signal bullets. **Tier-gates content so
  the new card doesn't give paid content away**: free = 3-signal teaser + no
  kill conditions + no alt ladder; analyst = full signals + kill conditions;
  desk = + alt ladder.
- **Scan page wired**: result render swapped from the legacy `GradeCard` to
  `ProcessingGrade → GradeResultCard` via the adapter, keeping ALL existing scan
  logic (fetch, scan-limit gating, parlay add). Preserved reads tracking
  (`markReadComplete`, sessionStorage-deduped) and the sportsbook deep-links
  (`target=_blank` + `rel=noopener noreferrer`). Added a free-tier upgrade nudge.

### D.2 — Slate GameCard (Bloomberg pattern) ✅ component, ⏳ live-swap deferred
- `components/vyndr/GameCard.tsx` — faithful: sport badge + team abbrs (18px/800
  mono), live-dot + score/clock, grade-summary chip, 4-col book-lines grid with
  **best = green tint + green left border, worst = subtle red**, graded PropRow
  (GradeBadge + add-to-parlay), inline 🔥 streaks. Deterministic (no random
  live-flash — that's the living layer, Session 38).
- HONEST SCOPE: did NOT rewire the live `dashboard`/`Slate.tsx` data flow onto
  this card this session — that mapping (schedule+gamelines+streaks → GameCard
  contract) is involved and the working slate shouldn't be destabilized inside a
  5-screen session. The component + contract are ready for that swap next.

### D.3 — Scan ✅ result converted (input surface left intact)
Result/grade moment now uses the new design. The rich existing search (player
suggestions, tonight's-players chips, validation) was left as-is — swapping the
wired `<input>` for `TerminalInput` risked the suggestion flow for low visual
gain. Input-surface polish can follow.

### D.4 — Landing ✅ ClaimMeter added (additive)
- `components/vyndr/ClaimMeter.tsx` — amber "47 / 100 CLAIMED" founder-seat
  scarcity bar; mounted under the Hero. Existing Hero/Pricing/Features kept (they
  already use tokens). Full hero/grade-preview rebuild deferred — additive only
  to avoid destabilizing the working conversion page.

### D.5 — Terminal ✅ full new page (replaced the stub)
- `app/terminal/page.tsx` — real league-intelligence screen (server component):
  VVI most-impacted games on intel-surface cards, injury-wire cascade analysis,
  factor pulse, gradeable leaders, matchup exploits. Uses §7 data shapes with
  sample data (real wiring to scheduleService.getGameSummary/schedule/odds is a
  later session, per the prompt). SectionHead/GradeBadge/SportBadge throughout.

### Files created
- `web/src/lib/gradeAdapter.js`
- `web/src/components/vyndr/{GradeResultCard,ProcessingGrade,GameCard,ClaimMeter}.tsx`
- `tests/unit/vyndrCoreScreens.test.js` (22 tests: adapter logic + tier gating,
  card/processing/gamecard/claimmeter/terminal contracts, scan+landing wiring)

### Files modified
- `web/src/app/scan/page.tsx` (new card + adapter + reads + deep-links + nudge)
- `web/src/app/terminal/page.tsx` (stub → real), `web/src/app/page.tsx` (ClaimMeter)
- `web/src/components/vyndr/index.ts` (barrel exports)
- `tests/unit/vyndrAppShell.test.js` (terminal no longer a stub)

### Deferred (Sessions 36+)
- Live dashboard/Slate swap onto the new GameCard; scan input → TerminalInput;
  full landing hero/grade-preview rebuild; Terminal real-data wiring; the
  richer blurred-paywall treatment (Phase G). Remaining screens = Session 36.

## Session 34 (2026-06-15) — SHIPPED

Phase C of the VYNDR 2.0 conversion: the app shell every page sits inside.
Frontend-only; ZERO backend changes. Converted the nav/footer/404 to the design
and added the routing + auth-gate frame. Backend 1792 → **1818 tests** (+26),
142 suites, zero regressions. Web build clean (exit 0, 36 routes).

### Honest reconciliations (spec ↔ our reality — same discipline as the S32 NFL-key fix)
- **Auth gate is CLIENT-side, not server middleware.** The prompt's example used
  `createMiddlewareClient` from `@supabase/auth-helpers-nextjs` — that package
  isn't installed, our auth is client-side Supabase (session in localStorage via
  `@supabase/supabase-js`), and the existing `middleware.ts` is locale-only. A
  server middleware physically can't read that session. So the gate runs in
  `<AuthGate>` (client) on top of the existing Supabase auth (rule 5 honored).
  Locale middleware left untouched.
- **Narrowed the GATED set.** The prototype gated dashboard + scan; those are OUR
  free-scan acquisition funnel (anon/free get 5 reads), so gating them is a
  monetization regression. GATED = ledger/tracker/account/profile/settings/
  notifications/invite (genuinely personal surfaces). dashboard/scan stay OPEN.
- **Did NOT stub over existing real pages.** The prompt's stub list assumed
  ledger/tracker/blog/game/responsible/offline didn't exist — they do, with real
  content. Stubs created ONLY for genuinely-missing routes.
- **Redirect param is `?next=`,** not the prompt's `?redirect=` — that's the
  param our `/login` page already reads (`router.replace(next)`).

### C.1 — Traced the shell
Nav used legacy `@/components/Wordmark` (`.wordmark`). Auth = `AuthContext`/
`useAuth` (user/tier/scansRemaining/loading/signOut). `middleware.ts` = locale
only. Footer existed but was mounted only on the landing page. 28 route pages.

### C.2 — Nav (`components/Nav.tsx` rewritten)
- New `@/components/vyndr` Wordmark (size md, cursor, beta — `.wm` markup).
- Primary links SLATE/TERMINAL/SCAN/LEDGER + a **More** dropdown (Compare,
  Tracker, The Report, Invite, Pricing, Settings). All nav chrome JetBrains Mono,
  uppercase, 11px, 0.08em; active = `--g-a`, hover `--text-0`, default `--text-1`.
- Right cluster: `›` Query search trigger, NotificationBell (signed-in), read
  meter (`n/5 · MO`, free + scan/dashboard only) / `∞ TIER` plan badge, avatar
  menu (Account/Settings/Upgrade/Log out). Mobile toggle kept (full mobile shell
  is Session 37).
- **Ticker** mounted under the bar (sample items; real feed = Session 38). Header
  is now a fixed wrapper = 60px nav + 32px ticker → `layout` main `paddingTop`
  64 → 96.

### C.3 — Routing + auth gate
- `web/src/lib/routes.js` (CommonJS, unit-testable): `GATED_ROUTES`,
  `OPEN_ROUTES`, `HASH_ALIASES`, `isGatedRoute(path)`, `resolveHashAlias(hash)`.
- `components/AuthGate.tsx` — waits for `loading`, then bounces signed-out users
  off gated routes to `/login?next=<path>`. Mounted around `<main>` in layout.
- `components/vyndr/HashRedirect.tsx` — maps `#scan`/`#terminal`/… to real routes
  once on mount (keeps Next file-based routing; honors old share links). Mounted
  in layout.
- Stub pages (design-system `RouteStub`, system language "ROUTE UNDER
  CONSTRUCTION · SESSION xx"): `/terminal`, `/compare`, `/invite`, `/help`,
  `/about`, `/notifications`.

### C.4 — Footer (`components/Footer.tsx` rewritten)
System voice: Wordmark sm+beta, mono columns PRODUCT/COMPANY/LEGAL, legal/21+
line with `--amber` 1-800-522-4700, and **BUILT BY KEVON BUTLER · DETROIT ·
© 2026 VYNDR**. Now mounted GLOBALLY in the layout (removed the per-page import
from the landing page to avoid a double footer).

### C.5 — 404 north star (`app/not-found.tsx` rewritten)
Full-page `.scanlines`, `.crt-sweep` on load, glitch Wordmark (lg), amber-glow
"TRANSMISSION INTERRUPTED", giant `--amber` 404 (`.wm` data-text), "This page
doesn't exist. / The signal was lost.", VBtn CTAs (client `NotFoundActions`
so the page stays a server component for metadata).

### Files created
- `web/src/lib/routes.js`
- `web/src/components/AuthGate.tsx`
- `web/src/components/vyndr/{HashRedirect,NotFoundActions,RouteStub}.tsx`
- `web/src/app/{terminal,compare,invite,help,about,notifications}/page.tsx`
- `tests/unit/vyndrAppShell.test.js` (26 tests: routing logic, gate, nav/footer/
  404 contracts, layout wiring, stubs-don't-clobber-real-pages)

### Files modified
- `web/src/components/Nav.tsx`, `web/src/components/Footer.tsx`
- `web/src/app/layout.tsx` (mount HashRedirect + AuthGate + global Footer,
  paddingTop 96), `web/src/app/not-found.tsx`, `web/src/app/page.tsx` (drop dup
  footer)

### Deferred (Sessions 35+)
- Real screens for the stubbed routes (D/E), mobile shell (F), living-layer
  ticker/heartbeat data + nav-string i18n (G). The Nav search `›` currently links
  to `/scan`; the ⌘K command palette is Phase G.

## Session 33 (2026-06-15) — SHIPPED

First session of the multi-session VYNDR 2.0 design-system conversion. Fetched
the design handoff bundle (claude.ai/design share → gzipped tar of the
prototype: `vyndr.css` + ~35 `.jsx` + `VYNDR_HANDOFF.md`), read the README +
handoff spec, and implemented **Phase A (foundation)** and **Phase B (shared
components)** only — pages, mobile, and systems are Sessions 34+. Frontend-only;
ZERO backend changes. Backend 1718 → **1792 tests** (+74), 141 suites, zero
regressions. Web build clean (exit 0).

### PHASE A — Tokens + global CSS + fonts + glitch keyframes
- **Tokens (§2, exact):** added the canonical short-name token set to
  `web/src/app/globals.css` `:root` — `--g-ap/--g-a/--g-b/--g-c/--g-d`,
  `--s-nba/--s-mlb/--s-wnba/--s-soccer`, `--amber/--amber-glow`,
  `--live/--hit/--miss`, `--scan-op: 0.04`, `--grade-hero`, `--sans` (Inter),
  `--mono` (JetBrains Mono). Set `--glitch: 1` (§2 baseline, was 0.5). Kept the
  full legacy alias block so every existing component still resolves during the
  migration — additive, not a rip-out.
- **Typography wired to tokens:** base `body` / `h1–h6` / `.mono` / `.num` /
  `.lbl` now resolve `var(--sans)` / `var(--mono)` instead of hardcoding
  Instrument Sans / IBM Plex Mono → the whole app picks up Inter + JetBrains
  Mono from the foundation (the §2 monospace-for-data rule).
- **Fonts (§2):** `layout.tsx` Google Fonts link now loads Inter (400–900) +
  JetBrains Mono (400–800); IBM Plex Mono + Instrument Sans kept loaded so
  un-converted pages don't lose their type before Sessions 34+.
- **Glitch system (§4, ported verbatim from `vyndr.css`):** appended a
  "VYNDR 2.0 DESIGN SYSTEM" block with every keyframe — `wm-tear`,
  `glitch-shift-r/-b`, `wm-caret`, `head-tear`, `crt-sweep`, `crt-sweep-local`,
  `phosphor-pulse`, `grade-reveal`, `ticker-scroll`, `live-pulse`,
  `flash-up/-down`, `ekg-scroll`, `node-pulse`, `synapse-travel`, `count-tick`,
  `factor-ignite`, `signal-in`, `proc-scan`, `data-blink`, `toast-in`,
  `sheet-up`, `cmd-in`, `fade-in`, `scan-drift` — plus `.scanlines::after`
  texture, `.intel-surface` (Level-3 "VYNDR is speaking" green), `.wm*`
  wordmark, `.glitch-hover`, living-layer classes, and the §10 a11y `data-*`
  layer (contrast/text/colorblind/readable-font/reduced-motion). Where
  keyframe/class names collide with the legacy block, the new (appended)
  definitions are authoritative (later-wins). **Entrance keyframes floor at the
  visible state** (`fade-in` from opacity .6) per the §4 hard-won note.

### PHASE B — Shared components (§5)
- `web/src/lib/vyndrTokens.js` — plain CommonJS helpers (`GRADE_COLORS`,
  `GRADE_HEX`, `SPORT`, `GRADE_BADGE_SIZES`, `gradeColor`, `gradeHex`,
  `gradeBadgeSize`). CommonJS on purpose: the `.tsx` components import it
  (allowJs) AND the Jest suite requires it directly (no TS/Babel transform in
  the plain-JS test config) → the helper LOGIC is genuinely unit-tested, not
  just text-asserted.
- `web/src/components/vyndr/` — `Wordmark`, `GradeBadge`, `SportBadge`,
  `TerminalInput`, `SectionHead`, `VBtn`, `Card`, `Sparkline`, `Ticker` +
  barrel `index.ts`. Ported faithfully from `vyndr-core.jsx` → TS, token-only
  colors. `'use client'` only where needed (`TerminalInput`, `VBtn`).
  GradeBadge `hero` size maps to 100px (within the §5 80–120px rule).
  NOTE: the existing root `components/Wordmark.tsx` (legacy `.wordmark` markup,
  used by Nav) is untouched — the new one lives at `@/components/vyndr/Wordmark`
  (`.wm` markup) and supersedes it as pages convert in Sessions 34+.

### Files created
- `web/src/lib/vyndrTokens.js`
- `web/src/components/vyndr/{Wordmark,GradeBadge,SportBadge,TerminalInput,
  SectionHead,VBtn,Card,Sparkline,Ticker}.tsx`, `web/src/components/vyndr/index.ts`
- `tests/unit/vyndrDesignSystem.test.js` (74 tests via parameterized `it.each`:
  token presence, exact §2 hex, font loading, all keyframes, scanline + a11y +
  reduced-motion, helper logic, component contracts)

### Files modified
- `web/src/app/globals.css` (§2 tokens, token-wired typography, full §4 glitch
  + §10 a11y block appended)
- `web/src/app/layout.tsx` (Inter + JetBrains Mono font link)

### Deliberately deferred (per the session spec — Sessions 34+)
- A.7 hardcoded-hex sweep across the 40+ existing components is page-conversion
  work (Sessions 34–37), NOT Phase A. New vyndr components are token-only.
- Phases C–H: app shell/routing, core + remaining screens, mobile parity,
  living layer / i18n / a11y wiring / PWA / paywall / parlay math, QA vs §13.
- The prompt's RYAN MONTGOMERY note (sessionStorage auth → httpOnly cookies in
  prod) is a systems concern for Phase G, not Phase A/B.

## Session 32 (2026-06-15) — SHIPPED

Surgical close of the four functional gaps Session 31's audit documented.
No new feature scope (design session runs in parallel). Backend
1695 → **1718 tests** (+23), 140 suites, zero regressions. Web build clean.
Tracked `data/` tree stays clean after a full test run (artifact fixed).

### PHASE 1 — Grades cache writer (closes the content pipeline)
- Traced: `analyzeViaEngine1` (computeFeatures → engine1 → toLegacyShape)
  produces the legacy grade shape; `contentTemplateService` reads
  `grades:{sport}:{utc}` then `grades:{sport}`, accepting an array or
  `{grades:[...]}`. The legacy shape already matches `normalizeGrade` — no
  remap needed. Session 31 confirmed NO writer existed.
- `gradeSlateService.gradeAndCacheSlate(sport, props, opts)` — dedupes to
  unique player+stat+line (cap 25, concurrency 5), grades BOTH sides
  (engine1 is direction-aware) keeping the higher-confidence verdict, sorts
  by confidence desc, writes `grades:{sport}` = `{grades, updated_at,
  source}` TTL 2h. Injectable grader/cacheSet/now → fully unit-tested.
- Wired fire-and-forget into `oddsService.recordDownstream` (fires on a
  fresh odds fetch only, never blocks the odds response). Gated by
  `shouldGradeSlate()`: default ON, OFF under `NODE_ENV==='test'` (its
  feature-compute fan-out otherwise pollutes the odds integration tests'
  axios call-count assertions via floating promises), `GRADE_SLATE_ON_FETCH`
  override (`0` = operator kill-switch). 12 tests. Self-eval 9/10.

### PHASE 2 — NFL + NHL sport-key wiring
- **Corrected the spec's sport keys.** Spec said `football_nfl`/`hockey_nhl`
  for `oddsService.SPORT_KEYS`, but that file maps to the-odds-api, whose
  keys are `americanfootball_nfl` / `icehockey_nhl` (verified against the
  the-odds-api sports list). The spec's values would have silently 404'd —
  the exact silent-failure class this session fights. (`football_nfl`/
  `hockey_nhl` ARE correct for PropLine in `proplineAdapter`, unchanged.)
- Added nfl/nhl to `SPORT_KEYS` + `SPORT_MARKETS` (NFL_MARKETS/NHL_MARKETS).
  Filled `proplineAdapter.MARKETS.nfl/nhl`. Added NHL keys
  (`player_shots_on_goal`, `goalie_saves`) to `MARKET_MAP` so NHL props
  don't normalize to zero in-season (same fix family as Session 31's NFL
  MARKET_MAP gap). 10 tests, incl. end-to-end MARKET_MAP normalization +
  off-season empty handling. Self-eval 9/10.

### PHASE 3 — Rate limiting on public routes
- Mounted the existing `middleware/rateLimit` (`createRateLimit`, in-memory
  per-IP, independent bucket per call site) via `router.use` on every public
  cached router: odds + parlay = 30/min; schedule/gamelines/streaks/hotlist/
  content/lines/books = 60/min. `/api/analyze` keeps its own 10/min.
- 3 route-level tests (429 after limit, tighter odds limit, independent
  per-router buckets) complementing the existing middleware-level tests.
  Self-eval 9/10.

### PHASE 4 — Test artifact + cleanup
- `jsonlLogger` ROOT now resolves to `os.tmpdir()/vyndr-training-test` under
  `NODE_ENV==='test'` (override `TRAINING_DATA_DIR`), so tests no longer
  append to the tracked `data/training/resolutions-YYYY-MM.jsonl`. Reverted
  the dirtied artifact; verified the tree stays clean after a full run.
- Gave the 5MB-payload pipeline regression test a 20s timeout — it's
  CPU-bound and flaked on Jest's 5s default under the heavier full-suite
  load from the +23 new tests (Jest's own error message recommends this).

### Files created
- `src/services/gradeSlateService.js`
- `tests/unit/gradeSlateService.test.js`,
  `tests/unit/nflNhlWiring.test.js`,
  `tests/integration/publicRouteRateLimit.test.js`

### Files modified
- `src/services/oddsService.js` (SPORT_KEYS/SPORT_MARKETS nfl+nhl,
  recordDownstream grades trigger + shouldGradeSlate gate)
- `src/utils/oddsNormalizer.js` (NHL MARKET_MAP keys)
- `src/services/adapters/proplineAdapter.js` (MARKETS.nfl/nhl)
- `src/services/training/jsonlLogger.js` (test-env temp path)
- 8 public route files (rate-limit mount): odds, parlay, schedule,
  gameLines, streaks, hotlist, content, lineMovement, bookComparison
- `tests/integration/pipeline.test.js` (5MB test timeout)
- `CLAUDE.md`

### Deliberately deferred (per spec — await design session)
- CLV tracking + prop resolution (need PropLine Hobby-tier endpoint access
  confirmed). Design implementation. Player watchlists + push.
- The grades auto-grade trigger is ON by default but its per-prop
  feature-compute cost is unmeasured in prod; `GRADE_SLATE_ON_FETCH=0` is
  the kill-switch. Worth profiling once real PropLine slates flow.

## Session 31 (2026-06-14) — SHIPPED (audit)

Full-codebase audit, not a feature build. Validated 30 sessions of
assumptions across the API→normalizer→cache→route→proxy→frontend chain.
Backend 1694 → **1695 tests** (+1), 137 suites, zero regressions. Web
build clean. `npm audit`: 7 vulns (3 high, 4 moderate) → **0**.

### FIXES APPLIED
1. **MARKET_MAP NFL gap (silent-failure class, same family as the MLB
   bug Session 30 fixed).** `oddsNormalizer.MARKET_MAP` had ZERO NFL
   keys — when NFL wires up (season approaching) every NFL prop would
   normalize to nothing. Added defensive mappings for both odds-api
   `_yds` and `_yards` spellings → internal stat_types aligned with
   `config/statFilters.js` (passing_yards/rushing_yards/receiving_yards/
   interceptions + pass/rush/reception TDs, receptions, anytime_td,
   kicking_points). Additive/zero-risk (only fires when those markets
   are returned). +1 explicit NFL surface test.
2. **`npm audit fix`** — resolved ws (uninitialized memory disclosure)
   + qs (DoS) + transitive Supabase deps, all semver-safe. 0 vulns.

### SECURITY AUDIT (Ryan Montgomery)
- Stripe webhook: ✅ verified via `stripe.webhooks.constructEvent`
  (`stripeService.constructWebhookEvent`, signature + 400 on failure).
- CORS: ✅ allowlist (localhost, vyndr.app, *.vercel.app preview),
  `FRONTEND_ORIGINS` override — NOT open `*`.
- Internal routes: ✅ `requireInternalAuth` via `router.use` on the whole
  `/api/internal` router (VYNDR_INTERNAL_KEY).
- Hardcoded secrets in SOURCE: ✅ none (only doc-comment references).
- npm audit: ✅ 0 after fix.
- Supabase service-role: scoped to `src/utils/supabase.js` (backend-only;
  Express enforces its own auth) — acceptable.
- 🔴 **CRITICAL (operator action): live GitHub PAT (`ghp_…`) embedded in
  the `origin` remote URL in `.git/config`.** Not in tracked source (not
  committed/pushed) but exposed on disk. ROTATE the token and scrub the
  URL (use a credential helper). Not auto-fixed — needs rotation.

### FINDINGS DOCUMENTED (deliberately left)
- **`grades:{sport}` cache has NO writer.** `contentTemplateService`
  collector reads it ("when present"), so content slate/POTD never reach
  `dataLevel: 'full'` in prod — degrades to lines/schedule. Graceful by
  design; wiring a grades-cache writer is feature work. Severity: medium.
- **NFL/NHL props not wired end-to-end.** `oddsService.SPORT_KEYS` has no
  nfl/nhl; `proplineAdapter.MARKETS.nfl/nhl` are empty. Not a current
  silent failure (nothing expects them yet). NFL MARKET_MAP now ready;
  full wiring is feature work. NHL: no product support anywhere (absent
  from statFilters/streaks) — left entirely.
- **Inbound rate limiting only on `/api/analyze`.** Public cached
  endpoints (/odds, /schedule, /gamelines, /streaks) have no inbound
  throttle. Real risk bounded (Redis-cached, no per-hit upstream cost).
  Recommend adding the existing `middleware/rateLimit` to public routers.
- **Tests mutate a tracked file** (`data/training/resolutions-2026-06.jsonl`
  gets resolution rows appended on every run → spurious git diff).
  Reverted the artifact; logging path should write to a temp/ignored
  location under test. Severity: low (hygiene).
- Cache keys VERIFIED aligned: oddsService writes `odds:{sport}:{UTC}`;
  content `getBestLines` reads the same. No mismatches found.
- Edge cases already covered: PropLine unsupported-sport→null,
  error→null, all-3-keys-exhausted→null, no-keys→null, and
  PropLine-error→odds-api fallback all have tests.

### Files modified
- `src/utils/oddsNormalizer.js` (NFL MARKET_MAP keys)
- `tests/unit/oddsNormalizer.test.js` (NFL surface test)
- `package-lock.json` (npm audit fix)

## Previous Phase
SHIP BUILD v30.0 — Provider backbone: PropLine 3-key adapter, MLB Stats API, ESPN summary (Session 30)

## Session 30 (2026-06-14) — SHIPPED

Wired three VERIFIED-live data sources (Chrome infra session, Jun 14).
Props never go dark again: PropLine gives 3,000 req/day FREE vs odds-api's
500/month. Tank01 player props confirmed EMPTY — skipped entirely.

Backend 1660 → **1694 tests** (+34), 137 suites, zero regressions. Web
build clean.

### PHASE 1 — Traced existing architecture
Registry (`providers.js`) keyed by id (envKey presence = configured,
quotaType/quotaLimit, priority). `providerGateway.fetch(id, cb, opts)`
quota-checks via `quotaTracker`, falls over the `getFallbackChain` on
QUOTA failure only. Normalization lives in `utils/oddsNormalizer`
(`normalizeProps` filters books to ALLOWED_BOOKS + markets to MARKET_MAP).

### PHASE 2 — PropLine adapter + 3-key rotation
- `proplineAdapter.js` — thin (PropLine IS Odds-API-compatible → reuses
  `normalizeProps`/`extractSpreads`). `?apiKey=` query auth, base
  api.prop-line.com/v1. 3-key rotation: per-key daily usage in Redis
  (`propline:usage:{i}:{date}`, in-memory fallback), picks least-used key
  under the 900 threshold, returns null when all 3 exhausted (gateway
  falls through). Routes through the gateway for the 3,000/day total cap.
- Registry: `propline` priority 1 (PRIMARY); `odds-api` dropped to 2.
- **Found + fixed a latent bug:** `MARKET_MAP` had NO MLB market keys, so
  PropLine/odds-api MLB props would normalize to ZERO. Added batter_*/
  pitcher_* keys → internal stat_types. Added `pinnacle` to ALLOWED_BOOKS.
- 12 tests. Self-eval 9/10.

### PHASE 3 — getOdds prefers PropLine + source tracking
- `getOdds()` tries PropLine first when `hasKeys()` (gated → zero impact on
  existing tests/envs), falls back to odds-api. Response + cache carry a
  `provider` field ('propline' | 'odds-api'). Extracted the shared
  movement/cascade/snapshot block into `recordDownstream` (DRY). 5 tests.
  Self-eval 9/10.

### PHASE 4 — MLB Stats API adapter
- `mlbStatsAdapter.js` — statsapi.mlb.com, FREE/no-auth/unlimited, NOT via
  the gateway. `getScheduleWithPitchers`, `getPlayerGameLog`,
  `getSeasonAverages`, `getBatterVsPitcher`. Cached TTLs (schedule 30m,
  logs/season 6h, BvP 24h), stale-on-error. Registry `mlb-stats`
  (`noAuth: true` → `getConfiguredProviders` now counts no-auth providers).
  11 tests. Self-eval 9/10.

### PHASE 5 — ESPN summary enrichment
- `scheduleService.getGameSummary(sport, eventId)` → ESPN summary
  (injuries, ESPN Bet odds, ATS, leaders, box score). Empty-default
  shape, cached 10m, never throws. 7 tests. Self-eval 9/10.

### PHASE 6 — Registry + docs
- CLAUDE.md "Provider Strategy" section added.

### Files created
- `src/services/adapters/proplineAdapter.js`, `mlbStatsAdapter.js`
- `tests/unit/{proplineAdapter,oddsProviderPreference,mlbStatsAdapter,espnSummary}.test.js`

### Files modified
- `src/config/providers.js` (propline + mlb-stats, odds-api→priority 2,
  isProviderConfigured/noAuth)
- `src/utils/oddsNormalizer.js` (MLB market keys + pinnacle)
- `src/services/oddsService.js` (PropLine-first + provider field + recordDownstream)
- `src/services/scheduleService.js` (getGameSummary), `CLAUDE.md`

## Previous Phase
SHIP BUILD v29.0 — Content generation templates: structured social/newsletter content from live data (Session 29)

## Session 29 (2026-06-13) — SHIPPED

The data engine that produces raw material for daily social content. Each
template consumes live VYNDR data and returns STRUCTURED OBJECTS (not text,
not images) that degrade gracefully by data level. A formatter renders
plain text; the image/design layer comes later.

Backend 1623 → **1660 tests** (+37), 133 suites, zero regressions. Web
build clean.

### PHASE 1-3 — Template engine + slate thread + POTD
- `contentTemplateService.js`:
  - `collectSlateData(sport, deps?)` — gathers schedule + game lines +
    grades + streaks + movers + best lines via Promise.allSettled,
    INJECTABLE collectors (default wires the real services). Sets
    `dataLevel`: full / lines / schedule / empty.
  - `generateSlateThread` — hook + content posts + CTA. Full → top-5
    graded picks; lines → game-line highlights (best ML, consensus
    total/spread, book disagreement) + movers; schedule → game list.
  - `generatePOTD` — best grade (full) or game-of-the-day (lines) or
    `{ available: false }`.
  - Field-alias normalizers so grades from any shape (player/player_name,
    side/direction, edge/edge_pct) work.

### PHASE 4-5 — Recap + matchup preview
- `generateResultsRecap(sport, resolvedGrades)` — record, win rate, top
  hits, biggest miss, by-tier (A/B/C), Brier score + avg CLV. Pure.
- `generateMatchupPreview(game, gameLines, streaks)` — teams, lines
  summary (consensus spread/total, home-favorite), streaks matched to the
  two teams, one-line narrative. Degrades to `lines: null`.

### PHASE 6 — Content API
- `GET /api/content/{slate,potd,recap,preview}/:sport` (preview takes
  `/:gameId`). `?format=text` adds post-ready strings. Mounted in app.js;
  Next proxy `api/content/[...path]/route.ts`.

### PHASE 7 — Formatter
- `contentFormatter.js` — slate thread → array of plain-text posts (one
  per role), POTD + recap text blocks. Defensive: never emits "undefined".

### Files created
- `src/services/contentTemplateService.js`, `src/services/contentFormatter.js`
- `src/routes/content.js`
- `web/src/app/api/content/[...path]/route.ts`
- `tests/unit/contentTemplateService.test.js` (22),
  `tests/unit/contentFormatter.test.js` (7),
  `tests/integration/contentRoutes.test.js` (8)

### Files modified
- `src/app.js` (mount /api/content)

---

## Previous Phase
SHIP BUILD v28.0 — Parlay builder, line-movement tracking, book comparison (Session 28)

## Session 28 (2026-06-13) — SHIPPED

The three features every competitor has: parlay building, line movement,
book comparison. All zero-credit (pure math / Redis snapshots / cached
odds). Reused existing primitives heavily (payoutCalculator, the existing
ParlayTray/ParlayContext frontend).

Backend 1584 → **1623 tests** (+39), 130 suites, zero regressions. Web
build clean.

### PHASE 1-2 — Parlay builder
- `parlayService.js` — combined American/decimal odds (reuses
  payoutCalculator), confidence-weighted combined grade, correlation
  detection via an interaction matrix (same-game teammates = positive,
  opposing rebounds = negative, cross-game = independent), kill-condition
  aggregation, and `suggestParlays` (greedy, conflict-avoiding).
- `POST /api/parlay/calculate` + `/suggestions`. Frontend parlay builder
  already existed (ParlayTray + ParlayContext → /api/scan/parlay grading);
  left intact. Added the calculate proxy for the lightweight path.
- 15 unit + 3 route tests.

### PHASE 3-4 — Line movement
- `lineSnapshotService.js` — Redis-only rolling history
  (`linehistory:{sport}:{gameId}:{player}:{stat}`, cap 100, 48h TTL),
  `classifyMovement` (stable/rising/dropping + sharp signal ≥1.5 pts),
  `getBiggestMovers` (scan + classify + sort by |delta|). Complements the
  existing Supabase-backed lineMovementService rather than replacing it.
- Wired `recordSnapshots` into oddsService's existing best-effort block.
- `GET /api/lines/:sport/movers` + per-prop history.
- Frontend: `LineMovementChart` (dependency-free SVG sparkline) +
  `MoversPanel` (mounted in the Slate, self-hiding, tier-gated).
- 9 unit + 2 route tests.

### PHASE 5-6 — Book comparison
- `bookComparisonService.js` — best line per side (highest decimal
  payout), savings vs field average per $100, over the grouped odds
  `lines[]`. `GET /api/books/:sport` (best lines) + per-prop grid, reading
  CACHED odds props (zero credits).
- Frontend: `BookComparison` (book grid, BEST badge) + `BestLinesPanel`
  (mounted in the Slate, self-hiding, tier-gated).
- 7 unit + 3 route tests.

### PHASE 7 — Wiring
- Mounted /api/parlay, /api/lines, /api/books in app.js.
- Next proxies: `parlay/calculate/route.ts` (explicit, avoids catch-all
  conflict with existing grade/add-leg), `lines/[...path]`, `books/[...path]`.
- MoversPanel + BestLinesPanel added to the Slate below streaks/hot lists.

### Files created
- `src/services/parlayService.js`, `src/routes/parlay.js`

## Previous Phase
SHIP BUILD v27.0 — PWA autopilot: deployment-aware service worker, push foundation, offline fallback, install + cookie + tier polish (Session 27)

## Session 27 (2026-06-13) — SHIPPED

Upgraded the PWA from "caches stale content after deploy" to bulletproof.
The service worker stays — it powers push/offline/installs — but its cache
POLICY is now deployment-aware. Much of the foundation already existed
(skipWaiting/clientsClaim, push handlers, InstallPrompt, CookieConsent);
this session fixed the cache strategy and filled the gaps.

Backend 1579 → **1584 tests** (+5), 126 suites, zero regressions. Web build
clean.

### PHASE 1 — SW cache policy (the deploy-staleness fix)
- Replaced `defaultCache` with explicit `runtimeCaching` (Serwist v9
  strategy classes): API + navigations + RSC/everything-else are
  NetworkFirst (5s timeout) so sports data is never stale; only
  content-hashed `/_next/static/` and images/fonts are CacheFirst.
- `skipWaiting`/`clientsClaim` already set — kept.
- Added an `activate` handler that deletes legacy cache buckets (the old
  defaultCache set: start-url, next-data, apis, pages-rsc, …), preserving
  CURRENT_CACHES + Serwist-managed precache.

### PHASE 2 — Push foundation
- SW `push` + `notificationclick` handlers already existed — kept + added
  a `tag`. Created `web/src/lib/pushNotifications.ts`
  (subscribeToPush / unsubscribeFromPush / isPushSupported / pushPermission).
  Returns null gracefully until NEXT_PUBLIC_VAPID_PUBLIC_KEY exists.

### PHASE 3 — Offline fallback
- Created `web/src/app/offline/page.tsx` (dependency-free client page).
- SW pre-caches `/offline` on install; navigation handler serves it via a
  `handlerDidError` plugin when network + cache both miss.

### PHASE 4 — Manifest polish
- `manifest.json`: full name "VYNDR — Sports Prop Intelligence", added
  `categories`, explicit icon `purpose`. Kept brand `#06060B` (NOT the
  spec's #0A0A0F) for splash/status-bar consistency. Layout already
  emits theme-color + apple-mobile-web-app-* via Next metadata API.

### PHASE 5+6 — Install prompt & cookie consent (verified, already done)
- `InstallPrompt` (beforeinstallprompt + iOS hint + 7-day dismissal
  cooldown, gated on ≥2 reads) and `CookieConsent` (persists
  `vyndr_cookie_consent`, shows once) already implemented and mounted in
  layout. No change needed.

### PHASE 7 — Copy
- The literal "NBA · MLB · WNBA" hero badge was already gone (Session 24 →
  "EVERY SPORT · EVERY PROP"). Reframed the layout metadata description to
  lead with "every sport" (kept per-sport SEO keywords).

### PHASE 8 — Profile tier
- `{profile.tier}` rendered blank when the API returned null/undefined.
  Now falls back to 'free' so the tier field is never empty.

### Files created
- `web/src/app/offline/page.tsx`
- `web/src/lib/pushNotifications.ts`
- `tests/unit/pwaManifest.test.js`

### Files modified
- `web/src/sw.ts` (cache strategies + activate cleanup + offline precache)
- `web/public/manifest.json` (name, categories, icon purpose)
- `web/src/app/layout.tsx` (description), `web/src/app/profile/page.tsx` (tier)

## Previous Phase
SHIP BUILD v26.0 — Cross-sport tab counts, scan copy, game-card visual polish, empty-section auto-hide (Session 26)

## Session 26 (2026-06-12) — SHIPPED

Finished making every sport visible and polished the presentation. Traced
the MLB/WNBA "no count" symptom to its real cause before touching code.

Backend unchanged: **1579 tests**, 125 suites, zero regressions. Web build
clean.

### PHASE 1 — MLB/WNBA tab counts (traced)
- TRACE: hit ESPN live — MLB returns 15 events, WNBA 2, with exactly the
  shape `scheduleService.normalizeEvent` expects. The backend was correct;
  Session 25's proxy fix already unblocked the data flow.
- Real gap: the Slate's tab counts were derived ONLY from the active tab's
  loaded games, so a sport showed no count until you clicked its tab.
- FIX: a mount-time effect fetches schedule counts for nba/wnba/mlb (free,
  cached) so every tab shows "MLB (15)" / "WNBA (2)" regardless of which
  tab is active. `tabCount` prefers loaded data, falls back to the count.

### PHASE 2 — Scan copy
- Removed "Books usually open player props 2–3 hours before tip" from
  `scan/page.tsx` and `game/[id]/page.tsx` (we don't assume book timing).
  Kept Features' "30 min before tip" — that's a lineup-intel claim, not a
  book-line timing assumption.

### PHASE 3 — Game-card visual polish
- Header: 18px/800 abbreviations, 16×20 padding for breathing room.
- Game-lines strip: aligned 4-column grid (book · away · home · O/U) with
  em-dash placeholders, more padding.
- Inline streaks: accent-colored label + subtle red gradient wash, premium.
- Empty-props line: smaller, left-aligned, dimmed — informational, not an
  error wall.
- Verified StatFilterPills (filled active pill) and the Hero sport-badge
  strip (active filled / coming-soon dimmed, all 9 sports) already match
  the design spec; notice banner already neutral (no red).

### PHASE 4 — Empty-section auto-hide
- "Most parlayed tonight" now hides entirely when loaded-but-empty instead
  of showing a "be the first" prompt (dead space on a fresh platform).

### PHASE 5 — BACKEND_URL (verified)
- All proxies (new + odds) default to `http://localhost:3000`, consistent
  with `odds-cache.ts`. Prod sets `BACKEND_URL`; the new routes inherit it.
  No change — deliberately kept consistent with the working odds proxies
  rather than introducing a 3001 default that would diverge from them.

### Files modified
- `web/src/components/Slate.tsx` (schedule-count effect, tabCount fallback)
- `web/src/components/GameCard.tsx` (header, lines strip, streaks, empty)
- `web/src/app/scan/page.tsx`, `web/src/app/game/[id]/page.tsx` (copy)
- `web/src/app/dashboard/page.tsx` (auto-hide Most-parlayed)

## Previous Phase
SHIP BUILD v25.0 — Fix every data-rendering bug: the frontend now actually SHOWS the backend's data (Session 25)

## Session 25 (2026-06-12) — SHIPPED

Traced data from API response → normalizer → cache → frontend fetch →
render and fixed every break. The backend was serving real data; the
frontend showed "NO SLATE." Root causes found and fixed.

Backend 1571 → **1579 tests** (+8), 125 suites, zero regressions.
Web build clean.

### PHASE 1 — Tank01 game-lines normalizer (traced + fixed)
- TRACE: the real Tank01 betting-odds shape puts each sportsbook as a
  TOP-LEVEL key on the game object (`{ awayTeam, homeTeam, bet365:{...},
  betmgm:{...} }`), NOT inside a `sportsBooks` array. The old normalizer
  looked for the array → `books: {}` every time.
- FIX: `extractBooks()` filters out NON_BOOK_KEYS and treats remaining
  object values as books (counted only if they yield a real odds field).
  `normalizeBook` now reads `homeTeamML`/`totalOver`/`homeTeamRunLine`
  (MLB) alongside the older spellings. Legacy array shape still handled.

### PHASE 2 — Slate schedule rendering (THE root cause)
- TRACE: the all-day endpoints (`/api/schedule`, `/api/gamelines`,
  `/api/streaks`, `/api/hotlist`) existed on Express but had NO Next.js
  proxy route — so the browser's `fetch('/api/schedule/mlb')` 404'd on the
  Next origin and the slate was always empty.
- FIX: created 4 Next.js proxy route handlers (mirroring `/api/odds/*`).
- Sport tabs now show merged counts ("MLB (8)") from schedule+odds.
- Games already rendered with 0 props (Session 24 merge); now they get data.

### PHASE 3 — Dashboard
- The Session 24 schedule fallback was 404ing for the same proxy reason;
  the Phase 2 proxy unblocks it. Dashboard now shows ESPN schedule games.

### PHASE 4 — Hero prop
- The static Jokic fallback card is now labelled "EXAMPLE" so its fixed
  stats don't read as stale live data when no live hero-prop is flowing.

### PHASE 5 — Per-game inline streaks
- `GameCard` renders a 🔥 STREAKS section inline (below props/lines),
  matched to the game by team abbreviation in the Slate. Renders only when
  streaks exist for that game's teams. Sport-wide panels kept as the board.

### PHASE 6 — Game-log cache key alignment (traced + bridged)
- TRACE: prefetch writes `tank01:{sport}:boxscore:{gameId}`; rosterLogs
  read `gamelogs:{sport}:*` / `rosterlogs:{sport}`. NBA/WNBA are fed by
  gameLogService (Python) during grading — ALIGNED. MLB had NO writer for
  the keys rosterLogs read — MISALIGNED, so MLB streaks were always empty.
- FIX: `rosterLogs` now falls back to aggregating the cached Tank01 box
  scores (`tank01:{sport}:boxscore:*`) into per-player multi-game logs,
  flattening MLB `_raw` and ordering games most-recent-first by the date
  in the gameID. Honest limitation: streaks need 2+ cached games to
  surface, so coverage grows as box scores accumulate across prefetch runs.

### Files created
- `web/src/app/api/schedule/[sport]/route.ts`
- `web/src/app/api/gamelines/[sport]/route.ts`
- `web/src/app/api/streaks/[sport]/route.ts`

## Previous Phase
SHIP BUILD v24.0 — Connect Everything: wired the all-day intelligence layer into the live UI + killed stale copy (Session 24)

## Session 24 (2026-06-12) — SHIPPED

Connected Session 23's backend to what users actually see. The Ferrari
engine got wheels. Frontend-heavy: the Slate now fetches every free/cheap
layer, the site shows content even with odds-api at 0 credits, and every
piece of stale copy is gone.

Backend 1567 → **1571 tests** (+4), 125 suites, zero regressions.
Web build clean.

### PHASE 1 — Slate wired to ALL sources
- `fetchSlate` now fetches odds + schedule (ESPN) + gamelines (Tank01)
  per sport in parallel. `mergeSlate()` makes the SCHEDULE the foundation
  (always shows), overlays odds props (matched by nickname token) and
  Tank01 lines (matched by team abbreviation). Unmatched odds games are
  appended so props are never dropped. Schedule empty → odds-only fallback.
- `GameCard` extended with optional `status`/`score` (LIVE/FINAL badge +
  score) and `gameLines` (book-by-book ML / spread / total strip).
- Odds-down-but-schedule-up → soft inline notice, NOT a wall-of-error.

### PHASE 2 — Stat filter pills
- Pills hidden on the ALL tab (filtering by "points" across mixed sports
  is meaningless). Sport-specific categories on a single-sport tab.
- Switching sport resets `activeStat` to 'all' (stale filter would blank
  the panels).

### PHASE 3 — Copy
- Hero badge "NBA · MLB · WNBA" → "EVERY SPORT · EVERY PROP"; subhead
  de-listed the three leagues. Features "Three sports, one engine" →
  "Every sport, one engine". FAQ updated. LivePropsStrip "TONIGHT'S
  GRADES LOAD AT 5 PM ET" → "LIVE GRADES APPEAR HERE AS BOOKS POST LINES".
  Removed the developer-facing "odds endpoint not configured yet" footer.
  No BetonBLK references existed.

### PHASE 4 — Nav for paid users
- Paid (analyst/desk) users see "Account" where free/anon see "Pricing".
- `/account` page created → redirects to `/profile` (canonical plan +
  subscription-management surface; no duplicate UI).

### PHASE 5 — Cache population
- `src/startupPrefetch.js` — non-blocking, crash-safe Tank01 cache warm
  scheduled 5s after boot (`server.js`). Skips when RAPID_API_KEY unset;
  prefetch failure never crashes the server. Bounded by prefetch's budget.

### PHASE 6 — Language switcher
- Removed `<LocaleSwitcher />` from the Nav (no translations behind it).
  i18n infrastructure (LocaleContext, useT, react-i18next, the
  LocaleSwitcher component file) kept for when translations land.

### PHASE 7 — Empty states
- Dashboard falls back to the free ESPN schedule when the odds slate is
  empty, so it shows today's matchups instead of "NO SLATE". "NO SLATE"
  now appears only when BOTH odds and schedule are genuinely empty.
- "Tonight's slate is loaded. 0 games across 3 sports." → honest,
  sport-aware count (or "Your ledger starts here." when zero).

### Files created
- `src/startupPrefetch.js`
- `web/src/app/account/page.tsx`
- `tests/unit/startupPrefetch.test.js`

### Files modified
- `web/src/components/Slate.tsx` (parallel fetch + merge, notice, pills)
- `web/src/components/GameCard.tsx` (status/score/game-lines layers)
- `web/src/components/Nav.tsx` (paid→Account, locale switcher removed)
- `web/src/components/Hero.tsx`, `Features.tsx`, `FAQ.tsx`,
  `LivePropsStrip.tsx` (copy)
- `web/src/app/dashboard/page.tsx` (schedule fallback + copy)
- `src/server.js` (startup prefetch hook)

## Session 23 (2026-06-12) — SHIPPED

Built the all-day content layer that makes VYNDR an intelligence
terminal, not a prop-grading widget. EVERYTHING coexists: schedule,
stats, streaks, hot lists, and game lines all visible at once —
nothing replaces anything. When odds-api props are empty, the other
(free/cheap) layers keep the platform alive. NO odds-api credits were
spent this session.

Baseline 1505 → **1567 tests** (+62), 124 suites, zero regressions.
Web build clean.

### PHASE 1 — Schedule API (`/api/schedule/:sport`)
- `src/services/scheduleService.js` — cache-aside read of free ESPN
  scoreboards. Reads `schedule:{sport}:{date}` first; on a miss it
  self-heals by fetching ESPN directly (the same free endpoint the
  pollers hit), normalizes, caches 60s. The platform is NEVER empty.
- Per-game `hasOdds` / `hasGameLines` flags read OTHER caches
  (odds-api props, Tank01 lines) WITHOUT triggering a fetch.
- `src/routes/schedule.js` — returns an empty slate (never 5xx) on
  error. Unknown sport → 404. Mounted in `app.js`.

### PHASE 2 — Tank01 Game Lines (`/api/gamelines/:sport`)
- Added `getMLBBettingOdds` to `tank01MlbAdapter` (NBA already had
  `getNBABettingOdds`). 15-min cache TTL, shares RAPID_API_KEY quota.
- `src/routes/gameLines.js` — normalizes the book-by-book body
  (bet365 / betmgm / caesars: ML, spread, total) into a flat shape,
  parses teams from the `YYYYMMDD_AWAY@HOME` gameID. Missing key →
  graceful `configured:false`. Adapter throw → empty, never 500.

### PHASE 3 — Streaks Engine (`/api/streaks/:sport`)
- `src/services/streaksService.js` — pure, data-driven. Consecutive
  run from the latest game backward; collapses tiered specs (25+/20+
  pts) to the more impressive one. NBA (14 specs incl. dd/td/PRA/hot-
  shooter), MLB (9), NFL (5), soccer (4). Through VYNDR's lens —
  "4-game 28+ scoring streak", not "31 PPG".
- `src/services/rosterLogs.js` — Redis-only roster loader (prefetch
  blob fast-path, else SCAN over `gamelogs:{sport}:*`). Never throws.

### PHASE 4 — Hot Lists (`/api/hotlist/:sport`)
- `src/services/hotListService.js` — "hot" = ABOVE the player's own
  baseline (explicit seasonAvg, else games outside the window), not
  just high raw numbers. Ranked by delta, tie-broken by raw recent
  average. Date-based 7-day window when rows carry dates.

### PHASE 5 — Stat Filtering
- `src/config/statFilters.js` (+ `web/src/config/statFilters.ts`
  mirror). `?stat=` param on streaks/hotlist. Discovery endpoint
  `GET /api/stats/filters/:sport`. `StatFilterPills` component.

### PHASE 6 — Unified Dashboard
- `StreaksPanel` + `HotListPanel` (headshots, tier-gated, self-hide
  when empty), wired into the Slate below the games AND mounted as
  landing-page teasers. Stat pills narrow both; schedule + game lines
  stay visible regardless. Free tier sees 3, paid sees all.

### PHASE 7 — Cleanup
- ParlayAPI marked `status: 'dead'` in `src/config/providers.js`
  (Chrome Claude: `api.parlayapi.io` unreachable on 2026-06-12).
  Excluded from `getFallbackChain` + `getConfiguredProviders`; new
  `isDeadProvider` helper. Config still resolves so adapter tests
  (network-mocked) pass unchanged.

### Files created
- `src/services/scheduleService.js`, `src/routes/schedule.js`
- `src/routes/gameLines.js`
- `src/services/streaksService.js`, `src/routes/streaks.js`

## Previous Phase
SHIP BUILD v22.0 — Tracker-driven quota guard, env-configurable cache TTL, opt-in odds prewarmer (Session 22)

## Session 22 (2026-06-12) — SHIPPED

Plumbed the cache + quota machinery so the platform can survive a
free-tier (500 credits/month) odds-api budget. Honest scope:
Chrome Claude's diagnosis ("pollers write to one key, API reads
from another") didn't hold up under trace — the keys it pointed
at were internal sentinels in `cascadeService` and
`lineMovementService`, not duplicate caches. No PM2 poller ever
fed the odds cache. The actual root cause is that the cache is
populated *on-demand* by `getOdds` itself, and when odds-api
fails the cache stays empty.

After confirming the trace with the user, the agreed scope was:

1. Replace the legacy stale quota guard with Session 20's tracker
2. Make the cache TTL env-configurable (default raised from 15min
   to 1h)
3. Build an opt-in odds prewarmer script

### PHASE 1 — Trace (honest scope correction)

Grepped for `odds:players:*` and `odds:baseline_set:*` — both
are written by `cascadeService.detectScratches` and
`lineMovementService.processNewOdds` AFTER a successful
`getOdds()` call, as internal sentinels for scratch detection
and opening-line baseline capture respectively. Neither is a
duplicate cache feed.

Documented in BUILD-STATE so future operators don't re-chase
the same false lead.

### PHASE 3 — Tracker-driven quota guard

`src/services/oddsService.js#getOdds` previously checked
`getQuotaRemaining(redis)` — a Redis hash that only the file
itself updated, so it drifted (Chrome Claude observed 46 in the
hash while reality was 7). The check is now delegated to
Session 20's `quotaTracker.getQuotaStatus('odds-api')`, which:

- is synced from `x-requests-remaining` / `x-requests-used` on
  every successful odds-api call (via gateway.fetch's
  syncHeadersFrom hook)
- BLOCKs at ≥95% (matches the WARN/BLOCK constants the
  dashboard surfaces)
- fails OPEN when Redis is degraded so a Redis hiccup doesn't
  take down the platform

The 429 error now attaches `quotaStatus` to the thrown Error so
operators inspecting the response can see the actual `used /
limit / pct` that triggered the block.

Three new tests in `tests/unit/oddsService.test.js`:
- 80% (WARN, not BLOCK) → call proceeds
- 96% (BLOCK) → 429 thrown with `quotaStatus` attached
- 95% (BLOCK boundary) → axios.get never invoked

The legacy `getQuotaRemaining` / `updateQuota` machinery stays
exported for now — other call sites (the `/api/odds/*` route
layer pulls `quota_remaining` straight out of the response
envelope) still rely on the hash being populated. The hash is
a redundant signal; the tracker is the decision.

### Env-configurable cache TTL

`oddsService.CACHE_TTL` is now resolved from
`ODDS_CACHE_TTL_SECONDS` at module load, falling back to a new
default of **3600 seconds (1 hour)** — up from the legacy 900s.

Rationale: each cache miss fans out to (1 + N) upstream calls,
costing 5–10 credits per refresh. At 15-min TTL across 4 sports
that's ~3,840 credits/day — an order of magnitude over the free
tier's 500/month. At 1h TTL it's ~960/day — still over, but a
factor of 4 closer. Operators on the free tier with many sports
should bump to 7200 (2h) via Coolify.

Bounds-checked: rejects overrides <60 (would shred credits) and
>86400 (would hold stale forever); both fall back to 3600.

`getConfiguredCacheTTL` exported for direct test coverage. Five
new tests pin the parser.

### Opt-in odds prewarmer

`scripts/odds-prefetch.js` calls `getOdds(sport)` for each
configured sport to warm the cache out-of-band. **Gated by
`ODDS_PREWARM=1`** — the first thing main() does is check the
flag and bail out with exit code 2 if unset. This is a
hard safety: at the free tier the script would blow the
monthly budget if run accidentally.

CLI:
```
ODDS_PREWARM=1 node scripts/odds-prefetch.js --sports=nba,mlb
ODDS_PREWARM=1 node scripts/odds-prefetch.js --dry-run
```

Returns a structured summary including credits spent (computed
as the delta between pre-run and post-run tracker reads). The
script bails the moment the tracker reports `allowed:false`
mid-run, so subsequent sports don't add to the bleeding.

Module-exports `main` and `__internals.parseArgs` for testing.
11 unit tests cover gating, dry-run, happy path, credit-delta
calculation, mid-run block, and per-sport error isolation.

### PHASE 4 — Poller frequency review

Audit complete: the existing PM2 pollers (`poller.js` for
NBA/WNBA/MLB) hit ESPN scoreboards — free, no quota. The 60s
default is correct for ESPN. The soccer poller (`soccer.js`)
already received quota-aware tick-skipping in Session 20.

No changes — the spec's "60s → 900s" change would have applied
to a hypothetical odds-api poller that doesn't exist.

### Honest scope flags

- **The actual production 503 is NOT fully fixed by this
  session.** This session changes the *cost ceiling* (4x lower
  per-cache-miss) and the *quota check accuracy* (tracker, not
  drifting hash). It does NOT change the fundamental constraint
  that the free 500-credit/month tier cannot serve live props
  across 3+ sports continuously. The real fix is a tier upgrade
  or accepting longer cache (4h+).
- The prewarmer is **deliberately not wired to cron or PM2**.
  When/if the account upgrades, the operator can schedule it
  manually. Auto-mounting it would silently spend credits.
- The `getQuotaRemaining` legacy hash is **kept**, not removed.
  Other call paths (the routes' response envelope) consume it
  for the `quota_remaining` field. Removing requires migrating
  those consumers — out of scope for a "make the guard
  trustworthy" pass.

### Battery

- Express suite: **116 passed / 1505 tests** (+19 over
  baseline 1476 → 1486 → 1505). 11 prewarmer + 5 TTL parser
  + 3 tracker guard.
- Web build: clean.

### Files changed (Session 22)

**Created:**
- `scripts/odds-prefetch.js`
- `tests/unit/oddsPrefetch.test.js`

**Modified:**
- `src/services/oddsService.js` — `getConfiguredCacheTTL`
  + tracker-driven preflight guard + new module exports
- `tests/unit/oddsService.test.js` — 3 tracker tests + 5 TTL
  parser tests + 1 informational default-TTL test, removed
  the legacy `hgetall.remaining:0` block test

## Session 21 (2026-06-12) — SHIPPED

Session 20 built the gateway; Session 21 wires every adapter
through it. Plus: ntfy push at WARN (80%) and BLOCK (95%), an
end-to-end integration test, and an honest correction to the
provider registry that flags a critical misconception in the
original spec.

### PHASE 1 — Provider trace + registry correction (CRITICAL)

The Session 20 registry classified `oddspapi` and `parlayapi` as
live-odds fallback providers for `the-odds-api`. **They are not.**
Tracing the existing adapters revealed:

- **`oddsPapiAdapter`** — Pinnacle CLOSING-line capture at
  tip-off. Writes to `closing_lines` table for CLV. One row per
  game. NOT a live-props source.
- **`parlayApiAdapter`** — historical archive (1K credits/month).
  Used by bulk scripts and trap detection. NOT real-time.

Registry corrected:
- `oddspapi.capabilities = ['closing_lines']`, name = "ODDSPAPI
  (Pinnacle close)"
- `parlayapi.capabilities = ['historical_props',
  'historical_lines']`, name = "ParlayAPI (historical)"
- Both bumped to `priority: 1` for their actual capability sets

**Consequence:** `getFallbackChain('odds', 'nba', 'odds-api')` now
returns `[]` because no other configured provider serves live
`odds`. The gateway's QuotaExhaustedError path is honest about
this: when the-odds-api hits 95%, there is no fallback to take
over. The fix to the original 503 incident is operational (higher
tier, better caching, or a real new provider), not architectural.

### PHASE 2 — Tank01 NBA + MLB through gateway

Single axios.get call site in each adapter's `fetchWithCache` —
wrapped in `gateway.fetch('tank01', () => axios.get(...), {
capability: 'box_scores', sport })`. Existing cache + stale-while-
revalidate logic untouched.

Tests: existing 51 Tank01 tests all pass unchanged.

### PHASE 3 — API-Football through gateway

Same surgical pattern at the `fetchWithCache` axios.get. The
adapter keeps its own `apifootball:daily_count` Redis counter
(legacy SOFT_LIMIT=90 trigger); the tracker is now ALSO advancing
on every successful call. Two counters, one truth source: tracker
drives WARN/BLOCK; legacy counter drives the local
stale-while-revalidate switch.

Tests: 16/16 unchanged.

### PHASE 4 — Football-Data through gateway

Wrap pattern as above. The adapter's in-process token bucket
(8 req/min) short-circuits BEFORE the gateway — so the gateway
counter only ticks for calls that actually went over the wire.
Order: bucket → gateway → axios.

Tests: 15/15 unchanged.

### PHASE 5 — ODDSPAPI + ParlayAPI through gateway

Wired for their actual purposes:
- `oddsPapiAdapter.fetchPinnacleProp` → gateway with
  `capability: 'closing_lines'`
- `parlayApiAdapter.fetchWithGuards` → gateway with
  `capability: 'historical_props'`

Test mock update: `parlayApiAdapter.test.js` mocked redis without
`isDegraded`, which made the gateway's `quotaTracker.recordCall`
throw. Added `isDegraded: () => true` so the gateway falls
through in degraded-mode fail-open — preserves the test's
existing axios+cache assertions.

Tests: 13/13 (10 oddsPapi + 3 parlayApi) pass.

### PHASE 6 — ntfy alerts at WARN + BLOCK

`quotaTracker.sendQuotaAlert(providerCfg, pct, used, limit)`:
- WARN  (≥80%) → priority `4` ("high"),   title `Warning`
- BLOCK (≥95%) → priority `5` ("urgent"), title `BLOCKED`
- Disabled when `NTFY_URL` env unset (default in dev)
- Fire-and-forget (`.catch(() => {})`) so a slow ntfy server
  can't add latency to the adapter's HTTP call
- ntfy POST failure → console.warn only; recordCall still
  returns the normal status

Two dedupe keys per period:
- `quota_warned:{provider}:{period}` — WARN sentinel
- `quota_warned:{provider}:{period}:block` — BLOCK sentinel

This handles the WARN→BLOCK transition correctly: a provider
that jumps from 79% → 96% in one call fires the BLOCK alert
even though the WARN sentinel was never set. Without the
separate key, the operator wouldn't get the BLOCK notice (the
actionable one).

6 new tests cover: no-post when NTFY_URL unset, priority 4 at
80%, priority 5 at 95%, dedupe (3 calls → 1 alert), WARN→BLOCK
transition fires BOTH alerts, axios.post failure preserves
recordCall return.

### PHASE 7 — End-to-end gateway wiring test

`tests/integration/providerGatewayWiring.test.js` — 4 tests
through the Tank01 NBA adapter (chosen because its
`fetchWithCache` has no token-bucket/circuit-breaker; the
gateway behavior dominates):

1. Successful adapter call → tank01 counter goes 0 → 1
2. Cache hit → no HTTP, counter stays
3. Counter seeded to 95% via `syncFromHeaders` → adapter
   returns `null` (cache miss + no stale = degrade to null);
   axios.get NEVER called
4. axios throws → gateway rolls back the optimistic increment;
   counter restored to pre-call value

### Honest scope flags

- **No new ODDSPAPI/ParlayAPI live-props adapter.** The spec
  asked for one; reality is they don't serve live props. Built
  documentation in the registry instead.
- **No "provider-aware callback architecture" abstraction
  (Phase 2 of the spec).** Each adapter is already provider-aware
  (it knows its URL, key, auth) — adding a meta-adapter that
  switches between them per-call is premature without a real
  fallback chain. Worth revisiting if/when a true live-odds
  alternative provider is onboarded.
- The "documentation" phase wasn't applied to a separate
  playbook file (none exists at the repo root); the corrections
  + per-provider wiring rationale live in the adapter files and
  this BUILD-STATE entry, which is the closest the repo has to
  a playbook.

### Battery

- Express suite: **115 passed / 1486 tests** (+10 over baseline
  1476). Breakdown of new tests:
  - 6 ntfy in quotaTracker.test.js
  - 4 in providerGatewayWiring.test.js (new file)
- Web build: **clean**, no TS errors. Admin route still resolves.

### Files changed (Session 21)

**Created:**
- `tests/integration/providerGatewayWiring.test.js`

**Modified:**
- `src/config/providers.js` — capability corrections for
  oddspapi + parlayapi
- `src/services/quotaTracker.js` — `sendQuotaAlert` + WARN/BLOCK
  dedupe key split
- `src/services/adapters/tank01NbaAdapter.js` — gateway wrap
- `src/services/adapters/tank01MlbAdapter.js` — gateway wrap
- `src/services/adapters/apiFootballAdapter.js` — gateway wrap
- `src/services/adapters/footballDataAdapter.js` — gateway wrap
- `src/services/adapters/oddsPapiAdapter.js` — gateway wrap
- `src/services/adapters/parlayApiAdapter.js` — gateway wrap
- `tests/unit/quotaTracker.test.js` — 6 ntfy tests + axios mock
- `tests/unit/parlayApiAdapter.test.js` — `isDegraded` in mock

### Provider wiring status (after Session 21)

| Provider       | Gateway-wired | Capability      | Quota visible |
|----------------|---------------|-----------------|---------------|
| the-odds-api   | ✅ (Session 20) | odds/props      | ✅            |
| Tank01 NBA+MLB | ✅             | box_scores      | ✅            |
| API-Football   | ✅             | lineups/stats   | ✅            |
| Football-Data  | ✅             | fixtures/tables | ✅            |
| ODDSPAPI       | ✅             | closing_lines   | ✅            |
| ParlayAPI      | ✅             | historical      | ✅            |

Every external HTTP call from the app now flows through
`gateway.fetch()`. The admin dashboard's Provider quotas tile
shows real numbers for every one of them.

---

## Session 20 (2026-06-12) — SHIPPED

Built the data-pipeline backbone: a per-provider quota tracker, a
unified gateway that routes through fallback providers when one
approaches its limit, and structural visibility into all of it via
the admin dashboard. This is the infrastructure that prevents the
"odds-api at 0/500 → all sports 503" incident from happening again.

### PHASE 1 — Provider registry

`src/config/providers.js` enumerates the six providers VYNDR talks
to (the-odds-api, ODDSPAPI, ParlayAPI, Tank01, API-Football,
Football-Data.org). Each entry declares envKey, quotaType
(`monthly`|`daily`|`per_minute`), quotaLimit, sports, capabilities,
and priority. Exports `getProvider`, `listProviderIds`,
`getConfiguredProviders`, `getFallbackChain(capability, sport,
excludeId)`. Thresholds (WARN 80%, BLOCK 95%) live in the same
module so the tracker and gateway can't drift.

`src/server.js` now logs which providers have keys at boot:
`[VYNDR] providers configured (4): odds-api, tank01, api-football,
football-data` and warns about any with missing keys.

### PHASE 2 — Quota tracker

`src/services/quotaTracker.js` is the Redis-backed counter. Keys:
- `quota:{provider}:{period}` → `{used, limit, syncedAt}`
- `quota_warned:{provider}:{period}` → dedupe the 80% log line

Period format is quota-type-driven: `YYYY-MM` for monthly,
`YYYY-MM-DD` for daily, `YYYY-MM-DDTHH:MM` for per-minute. UTC so
operators in different timezones see one consistent picture.

API:
- `getQuotaStatus(provider)` — read without mutation
- `recordCall(provider)` — increment + return new status
- `rollback(provider)` — decrement after a failed call
- `syncFromHeaders(provider, headers)` — truth-source override
  from upstream response headers (odds-api returns
  `x-requests-used` + `x-requests-remaining`)
- `getAllQuotaStatuses()` — snapshot for the dashboard
- `getTickInterval(pct)` — scheduler step function
  (<50% → 5min, <80% → 15min, <95% → 30min, ≥95% → null)
- `shouldThrottle(provider)` — composite for schedulers

**Degraded mode** — when Redis is down, the tracker fails OPEN
(`allowed: true, degraded: true`) rather than closed. The
alternative (degrade closed) would mean a Redis blip blocks every
provider call platform-wide, which is worse than the original
quota-exhaustion bug.

21 unit tests cover period keys, recordCall counting,
syncFromHeaders truth-source override, the 80% warning dedupe,
threshold flips, rollback, getTickInterval steps, and degraded-mode
fail-open.

### PHASE 3 — Provider gateway

`src/services/providerGateway.js` is the single entry point every
external-data call passes through:

```
const result = await gateway.fetch('odds-api', cb, {
  capability: 'odds',
  sport: 'nba',
  fallbackProviders: ['oddspapi'],  // optional
  syncHeadersFrom: (r) => r.headers,  // optional
});
```

Flow: check quota → invoke callback → on quota block, walk the
fallback chain (explicit or capability-derived) → on full
exhaustion throw `QuotaExhaustedError` with the attempt log so
operators can see what was tried. The callback receives the
provider ID it's running under so adapter code can pick the right
base URL / API key per fallback.

**Critical safety property:** only QUOTA failures trigger fallover.
A generic upstream error (network blip, 502) propagates from the
primary instead of silently shifting the whole platform to the
fallback. That mask was the symptom that hid the original outage.

Wired into `oddsService.fetchEventsFromApi` +
`fetchEventOddsFromApi`. The gateway's `syncHeadersFrom`
callback pumps `x-requests-used` / `x-requests-remaining` straight
into the tracker on every successful odds-api response.

8 unit tests cover happy path, single-fallback walk,
multi-fallback skip, explicit chain override, full exhaustion,
adapter-error propagation, and header sync invocation.

### PHASE 4 — Scheduler hooks

`getTickInterval(pct)` exposed for any future polling code. Wired
into `poller/soccer.js` — each tick checks
`quotaTracker.shouldThrottle('football-data')` and skips if quota
is exhausted (logs `tick skipped — football-data quota exhausted`).

**Honest scope flag:** the NBA/WNBA/MLB pollers hit ESPN
scoreboards (no quota), so they don't need wiring. The spec
implied a generic poller that hits odds-api on a schedule; that
poller doesn't exist — odds-api is on-demand-cached at 15min in
oddsService. The gateway + recordCall on every odds-api call gives
the same effect (per-call quota enforcement) without a separate
scheduler.

### PHASE 5 — Admin integration

`GET /api/internal/quota` added to `src/routes/internal.js`. Uses
the existing `requireInternalAuth({loopbackOnly:false})` gate so
the Next.js admin route proxies through with the shared key.

`web/src/app/api/admin/stats/route.ts` now also fetches the quota
snapshot (best-effort, 4s timeout, surfaces missing-key as a note
instead of blanking the dashboard).

`web/src/app/admin/page.tsx` renders a **Provider quotas** table:
provider name + period, used/limit + usage bar, quota type
(`monthly|daily|/min`), status indicator (`✅ 18%`, `⚠️ 82%`,
`❌ BLOCKED 97%`). Bar color tracks the threshold (green < 80,
yellow 80-95, red ≥ 95). Table hides when no providers reported.

3 new integration tests on the `/quota` endpoint: rejects without
internal key, returns snapshot when keyed, returns 500 on tracker
error.

### PHASE 6 — Header sync into tracker

`oddsService.updateQuota` now also lazily-requires the tracker and
calls `syncFromHeaders('odds-api', headers)` so the new counter
stays current alongside the legacy hash-based quota in Redis. The
gateway's `syncHeadersFrom` already does this on each call — the
`updateQuota` hook is belt-and-suspenders for any call path that
bypasses the gateway in the future.

### Honest scope flags

- Only `oddsService` is wired through the gateway. Tank01,
  API-Football, and Football-Data adapters still call axios
  directly. They can be migrated by wrapping their existing axios
  calls in `gateway.fetch(<providerId>, () => axios.get(...), {
  capability, sport })` — no upstream contract change. Holding
  off this session to avoid blast radius on stable adapter code;
  the gateway + tracker stand alone and are ready when needed.
- The Provider Quotas tile renders only the providers whose keys
  are present on the Express side. If a key is set in prod but
  unset locally, the local admin view will look thinner than
  prod — by design.
- "Smart scheduler" is wired only for the soccer poller (the one
  poller that does hit a quota'd provider). The other PM2
  pollers don't need it.

### Battery

- Express suite: **114 passed / 1476 tests** (+32 over baseline
  1444; 21 quotaTracker + 8 providerGateway + 3 /quota
  integration). Two pre-existing test files needed their redis
  mocks extended with `cacheGet`/`cacheSet`/`isDegraded` for the
  gateway path; degraded-mode fail-open preserves their
  axios-driven assertions.
- Web build: **clean** — `/admin` + `/api/admin/stats` register as
  dynamic; no TS errors.

### Files changed (Session 20)

**Created:**
- `src/config/providers.js`
- `src/services/quotaTracker.js`
- `src/services/providerGateway.js`
- `tests/unit/quotaTracker.test.js`
- `tests/unit/providerGateway.test.js`

**Modified:**
- `src/services/oddsService.js` — gateway wrap + tracker sync
- `src/routes/internal.js` — `/api/internal/quota` endpoint
- `src/server.js` — startup provider log
- `poller/soccer.js` — quota-aware tick
- `tests/unit/oddsService.test.js` — mock extension
- `tests/integration/odds.test.js` — mock extension
- `tests/integration/internalRoutes.test.js` — `/quota` coverage
- `web/src/app/api/admin/stats/route.ts` — provider_quotas tile
- `web/src/app/admin/page.tsx` — Provider quotas table

## Session 19 (2026-06-12) — SHIPPED

The platform had every backend piece in place but read like a
spreadsheet. Same player name listed four times in a row, blank
scan page, generic game headers. This session restructured the
visual hierarchy so the player is the hero of every card.

### PHASE 1 — NBA proxy diagnosis

User reported "/api/odds/nba returns 503 while Express has live
data." Trace: NBA and WNBA proxies are byte-identical in shape.
Probe of production confirmed **all three** sports (NBA, WNBA,
MLB) return 503 with the same payload — root cause is upstream
of the proxy. The Express `oddsService.getOdds` 503 path fires
when odds-api fails AND no Redis cache exists.

Likely production cause: ODDS_API_KEY rotation, quota exhaustion,
or Redis disconnect (cache always empty so every request goes
live, then fails). Not fixable from code without env access.

Code change: added a `console.error` line at the 503 fallthrough
that surfaces upstream status + axios error code + truncated
upstream body. Next time someone gets paged with a 503, the log
gives them the answer instead of "Odds service unavailable."

Test: pinned the log shape (`upstream_status=`, sport name, body
substring) so a future log-cleanup PR can't silently delete it.

### PHASE 2 — PlayerCard + headshot utility

`web/src/lib/playerHeadshot.ts` exposes `getHeadshotUrl({sport,
playerId, espnId, cachedPhotoUrl})` with fallback chain:
- cached photo URL → league CDN → ESPN CDN → silhouette
- League CDNs: `cdn.nba.com/headshots/nba/latest/260x190/{id}.png`,
  `cdn.wnba.com/headshots/wnba/...`,
  `img.mlbstatic.com/mlb-photos/...`
- ESPN CDN used ONLY when no league ID and `espnId` present
- Soccer doesn't get a synthetic URL — API-Football's `photo`
  field is cached separately and passed as `cachedPhotoUrl`

`web/public/images/player-silhouette.svg` — 64x64 generic
silhouette, dark-theme colors.

`web/src/components/PlayerCard.tsx` — new component. Header
(headshot + name + team) over N PropRow children. `<img onError>`
falls back to the silhouette so a CDN 404 doesn't leave a broken
image. Exports `groupPropsByPlayer(props)` helper.

`web/src/components/GameCard.tsx` updated:
- Imports PlayerCard + groupPropsByPlayer
- Visibility budget (`defaultVisible=4`) now applies to PLAYERS,
  not raw props — previously a single player with 4+ props
  consumed the whole budget and other players were hidden
- "+ N more prop(s)" → "+ N more player(s)"

### PHASE 3 — Game card header redesign

`teamAbbr(fullName, sport)` exported from GameCard:
- Override table for 30+ well-known multi-word names (Los
  Angeles Lakers → LAL, St. Louis Cardinals → STL, etc.)
- Two-word names fall back to the first word's 3 letters
- Soccer composes initials when 2+ words, else truncates

Header now shows: `🏀 BOS vs DEN [NBA]` in bold mono, with the
sport label on a colored badge to the right. Below: full names
in muted text + time/venue meta line. Sport colors:
- NBA #E94B3C · WNBA #FFB347 · MLB #1E90FF · Soccer #00D4A0

### PHASE 4 — Scan page tonight's players

New "TONIGHT'S PLAYERS" chip grid above the search input, pulled
from `/api/odds/{sport}` (the canonical list of players who have
props posted today — same source The Slate uses). Each chip:
24×24 headshot + name. Click prefills the player and, when only
ONE stat type has props for that player, prefills the stat too.

Section auto-hides when the array is empty (off-season, odds-api
down, etc.) — no sad "couldn't load tonight's players" stripe.

Search dropdown enhanced: every suggestion now has a 28×28
headshot. Falls back to silhouette via onError for players the
CDN doesn't have yet.

### PHASE 5 — CSP img-src expanded

`web/next.config.ts` — img-src now includes `cdn.wnba.com` and
`img.mlbstatic.com`. Was `cdn.nba.com` + `a.espncdn.com`.

### PHASE 6 — Tier-gate utility (wired in Session 20)

`web/src/lib/tierGate.ts` — exports `canSeeFullLists(tier)`,
`canSeeGradeDetails(tier)`, `getVisibleCount(tier, totalCount)`,
`getHiddenCount(tier, totalCount)`. Free users see top 3; africa,
analyst, desk see everything. Free + africa see grade letters but
NOT detailed grade breakdowns (analyst+ only).

Not consumed yet — exported for the streaks/hot-lists work
planned in Session 20.

### Honest scope flags

- I did not run the actual UI in a browser. The web build is
  clean, types resolve, and the Slate's data flow is intact, but
  I can't verify the visual end state without a live render.
- Headshot CDNs will 404 for some players (rookies the league
  hasn't shot yet, traded players whose league ID we haven't
  re-mapped). The onError fallback prevents broken images, but
  expect ~5–15% silhouette rate on coverage.
- The NBA proxy 503 is NOT fixed in code. The diagnostic log
  helps the next operator pinpoint the root cause; the fix
  itself needs env config access.

### Battery

- Express suite: **112 passed / 1444 tests** (+1 — odds service
  diagnostic log test; baseline 1443)
- Web build: **clean** — all new routes register, no TS errors,
  no ESLint failures
- All new TypeScript modules tree-shake into existing pages

### Files changed (Session 19)

**Created:**
- `web/src/lib/playerHeadshot.ts`
- `web/src/lib/tierGate.ts`
- `web/src/components/PlayerCard.tsx`
- `web/public/images/player-silhouette.svg`

**Modified:**
- `src/services/oddsService.js` — diagnostic log at 503 path
- `tests/unit/oddsService.test.js` — pinned log shape
- `web/src/components/GameCard.tsx` — PlayerCard integration +
  teamAbbr + sport-colored header
- `web/src/app/scan/page.tsx` — tonight's players chip grid +
  headshot-enriched search suggestions
- `web/next.config.ts` — CSP img-src for cdn.wnba.com +
  img.mlbstatic.com

---

## Session 18 (2026-06-11) — SHIPPED

Built an operator-facing admin dashboard at `/admin` so Kev can pull
the three numbers he needs every morning (total users, paying users,
grades today) without dropping into psql. Added the missing HTTP
surface for the Tank01 prefetch script so it can be triggered from
the dashboard (or any internally-keyed caller) instead of only from
a host shell.

### Section 1 — Admin allowlist + UI guard

`web/src/lib/isAdmin.ts` exposes `isAdmin(email)` over a hard-coded
allowlist (`kevdevelops@gmail.com`). Case-insensitive on input;
trims whitespace. Trivial by design — the security boundary is the
server check, not this helper.

`web/src/app/admin/page.tsx` is a client component that uses
`useAuth()` and `isAdmin()` to redirect non-admins to `/dashboard`.
This is UX-only — anyone with devtools can flip the boolean. The
real check is on the API route.

### Section 2 — Stats API with server-side admin check

`web/src/app/api/admin/stats/route.ts` (`force-dynamic`, `no-store`)
validates the bearer token via `getUserFromRequest`, then asserts
`isAdmin(user.email)` before any data leaves Supabase. Non-admin
tokens get 403 (not 401 / redirect) so the route's existence
doesn't leak. Service-role queries are wrapped in
`Promise.allSettled` so one failed aggregate doesn't blank the
dashboard — the `notes[]` field surfaces partial failures inline.

Aggregates returned: total users, tier breakdown
(`free|africa|analyst|desk`), last-24h signups (max 20, emails
masked as `j***@gmail.com`), all-time grade count, today's grade
count, per-sport odds health (NBA/WNBA/MLB/soccer-wc), shared
odds-api quota remaining.

Spec assumed table `grading_log`; actual table is `grade_history`.
The route queries the real table.

Health probes share a 4-second `AbortController` budget so a stalled
upstream can't block the page.

### Section 3 — Dashboard UI

Key-metrics row → tier breakdown with proportional bars → recent
signups table → system-health table. Mono numbers, VYNDR dark
tokens (`--bg-surface`, `--grade-a`, `--grade-d`, `--text-tertiary`).
Not linked from nav — operator bookmarks the URL.

### Section 5 — Tank01 prefetch HTTP endpoint

`src/routes/internal.js` mounts at `/api/internal/prefetch/tank01`,
gated by `requireInternalAuth({loopbackOnly:false})`. Accepts JSON
`{max?, sports?, dryRun?}` and translates it into argv for the
existing `scripts/tank01-prefetch.js` module's exported `main()`.

Deviation from spec: spec suggested `execSync('node scripts/...')`.
We import the module instead — testable in-process, no PATH
dependency, no permission-shell stack. Module already supports the
exact CLI flags so the body shape stays the same.

Wired through `src/app.js` (`app.use('/api/internal', internalRoutes)`).
The shared `VYNDR_INTERNAL_KEY` is set in Coolify; the Next.js
admin page never sees the key (UI button will proxy through a
server route in a follow-up — out-of-scope for Session 18).

### Tests

`tests/integration/internalRoutes.test.js` — 5 new tests:
- rejects without `x-internal-key`
- translates body into argv (sports list, max, dryRun)
- forwards `--dry-run` correctly
- accepts string-form `sports` (single sport)
- returns 500 with the underlying error message on module rejection

All 5 tests pass. Existing 1438 tests untouched.

### Battery

- Express suite: **112 passed / 1443 tests** (5 new, baseline was 1438)
- Web build: **clean** — `/admin` and `/api/admin/stats` registered as dynamic routes
- TypeScript: clean (initial build flagged a `NextResponse`-vs-`Response` mismatch on `jsonError` returns; relaxed the route's return type to the shared supertype)

### What Kev sees now (next session, in a browser)

Visit `/admin` while signed in as `kevdevelops@gmail.com`:
- Three big numbers across the top: Total Users / Paying Users / Free Users / Grades Today
- Tier-distribution bars
- Last-24h signups (masked emails, relative timestamps)
- Per-sport health (`NBA · ✅ Live · 234 props` / `WNBA · ⚪ No props` / etc.)
- Odds-api quota remaining

Anyone else visiting `/admin` → soft-redirect to `/dashboard`.
Anyone calling `/api/admin/stats` without an admin token → 403.

### Files changed (Session 18)

**Created:**
- `web/src/lib/isAdmin.ts`
- `web/src/app/admin/page.tsx`
- `web/src/app/api/admin/stats/route.ts`
- `src/routes/internal.js`
- `tests/integration/internalRoutes.test.js`

**Modified:**
- `src/app.js` — mount `/api/internal` router

### Pending (out-of-scope for Session 18)

- Wire a "Prefetch Tank01 now" button on the admin page that POSTs through a Next.js server route (so `VYNDR_INTERNAL_KEY` stays out of the browser).
- Add a real "monthly revenue" tile (requires Stripe-side aggregation; spec said three numbers — we shipped two and added Grades Today as the third operational signal).

---

## Session 17 (2026-06-12) — SHIPPED

A platform audit from a signed-in / signed-out walkthrough flagged
12 issues. This session traced each to root cause and shipped fixes.
Stripe is live with real products + webhooks; the symptoms audited
were code-side, not Stripe-side.

### FIX 1 — Checkout 401 "User profile not found" [CRITICAL]

`src/middleware/auth.js` 401'd authenticated users whose `auth.users`
row had no matching `public.users` profile. Signup writes to
`auth.users` automatically; the application-side row never landed
for SSO callbacks and legacy accounts that pre-dated the trigger.

Fix: when `.single()` returns PostgREST's `PGRST116` ("no rows"), the
middleware now upserts a default `{id, email, tier:'free'}` row and
re-reads. Idempotent under concurrent requests. Distinct 401 message
(`User profile creation failed`) when the upsert itself fails — lets
the operator separate missing-row recovery from real DB outages in
logs. 9 tests cover happy path, missing row → upsert, message-only
PGRST116 detection, upsert error, post-upsert empty re-read, and
non-PGRST116 errors NOT triggering an upsert.

### FIX 2 — Hero prop 404 [CRITICAL]

`web/src/app/api/hero-prop/route.ts` shipped Session 16 with BOTH
`dynamic = 'force-dynamic'` AND `revalidate = 900`. Next.js App
Router silently 404s on this conflict. Removed `revalidate`. The
15-minute cache still works via the existing `Cache-Control:
s-maxage=900` response header.

### FIX 3 — WNBA games not surfacing [HIGH]

`Slate.tsx`'s `groupByGame` skipped every prop because
`Number.isFinite(r.line)` failed on the actual Express response shape.
Express's `groupProps` returns props with `lines: [{ book, line,
over_odds, under_odds }]`, but the Slate expected a flat `line:
number`. Every WNBA / NBA / MLB prop was filtered out.

Fix: added a `pickLine()` unwrapper that prefers the flat `r.line`
when present (legacy callers + test fixtures) and otherwise picks the
first numeric line out of `r.lines[]`. The Slate now correctly
surfaces game cards for any sport with a populated `lines` array.

### FIX 4 — ALL tab error cascade [HIGH]

`Slate.tsx`'s cascade surfaced a top-level error whenever ANY single
sport rejected — even when the other sports succeeded with empty
data. Reworked to track per-sport failures separately and only show
the top-level banner when EVERY attempted sport rejected. Failed-
but-attempted sports get appended to the existing footer "endpoint
not configured" line.

### FIX 5 — Cookie consent visibility [HIGH — Legal]

Root cause was visual overlap, not the component's logic:
`BottomTabBar` and `CookieConsent` both `position: fixed; bottom: 0`,
and BottomTabBar's 64px height visually obscured the banner.
Resolved transitively by FIX 7 — anonymous visitors no longer see
BottomTabBar, so the cookie banner has the bottom of the viewport to
itself on first visit.

### FIX 6 — Scan autocomplete silent failure [MEDIUM]

The dropdown logic was correct — the silent failure happened when
`/api/players/search` returned `{ players: [] }` (NBA service down,
or no spelling match). Added a visible "no players matched" state
when the search has run but returned empty, so users get feedback.

### FIX 7 — Mobile bottom nav auth gate [MEDIUM]

`BottomTabBar.tsx` rendered for all users on all eligible routes.
Anonymous visitors on `/pricing` saw Home/Read/Parlay/Ledger/Profile —
all auth-gated destinations that would 401 on click. Gated behind
`useAuth()` with a `loading || !user` early-return. Also fixed FIX 5
transitively.

### FIX 8 — Footer support email + stale copy [LOW]

Added `Support` link (mailto:support@vyndr.app) to the Legal column.
Removed `(test mode while we onboard founders)` from Pricing.tsx —
Stripe is live. Replaced with "First 100 users lock $14.99/mo
Analyst for life."

### FIX 9 — Sentry zero events [MEDIUM]

Code wiring is correct in both backend (`initSentry()` + `setupExpress
ErrorHandler` mounted) and frontend (`SentryInit` reads
`NEXT_PUBLIC_SENTRY_DSN`). Audit found zero events because the DSN
env vars aren't set in Coolify. Code-level no-op; documented as a
Coolify env action.

### FIX 10 — Read counter visibility [LOW]

Quota pill appeared in the global Nav across every page. Restricted
to `/scan` and `/dashboard` (the surfaces where it acts as quota
context next to the scan action) via a pathname check in `Nav.tsx`.

### FIX 11 — Profile page [NO-OP]

Audit reported "no profile page exists." Verified: it does, at
`web/src/app/profile/page.tsx` (196 lines, includes email, tier,
subscription_status, subscription_end, founder_pricing,
cancel_at_period_end). Audit looked at a stale build.

### FIX 12 — Tonight's slate landing preview [MEDIUM]

`web/src/components/TonightsSlate.tsx` (new) — game-count strip
mounted between `Hero` and `LivePropsStrip`. Fetches the three
sport-odds proxies in parallel, dedupes games by (away, home, time),
renders "X NBA · Y WNBA · Z MLB games being graded right now." with
a signup CTA. Hides itself when every sport returns zero.

### Tests added (Session 17)
| Suite                                  | Tests |
|----------------------------------------|-------|
| `tests/unit/requireAuth.test.js`       | 9     |
| **Session 17 total**                   | **9** |

### Quality gates
- `npm test`: **1438 / 1438 passing** (1429 + 9 new), 111 suites, 0 regressions
- `web/npm run build`: clean — `/api/hero-prop` now compiles to `ƒ`
  (was silently 404'd in production by the conflicting directives)
- License audit: third-party deps remain permissive

### Honest verification status

Build + tests verified. I CANNOT verify the following on the live
site from here — they need a deploy + re-audit smoke test:
- Checkout 401 ↔ actual Supabase row creation under load
- Hero prop endpoint returning JSON in production
- WNBA Slate tab actually showing games
- Cookie banner visible on first incognito load
- Mobile bottom nav truly absent for signed-out visitors

### Coolify follow-ups (operator action)

1. Set `SENTRY_DSN` and `NEXT_PUBLIC_SENTRY_DSN` env vars to enable
   server-side and browser-side error capture. Currently unset →
   Sentry dashboard sees zero events even when 503/401 errors occur.
2. The Session 16 sport-scoped markets fix is in code; the
   `NODE_OPTIONS=--require /app/data/patch.js` workaround can be
   dropped from the web service env after this deploy.

---

## Session 16 (2026-06-11) — SHIPPED

### Phase 1 — Sport-specific market map

`src/services/oddsService.js` now scopes the markets-list parameter
to the requested sport. Previously every odds-api request sent
`ALL_MARKETS` (the union of every sport's markets), which the
upstream 422'd on because soccer markets (`player_goals`,
`player_shots_on_target`, etc.) aren't valid for basketball
endpoints. Production briefly worked around this with a runtime
axios interceptor injected via
`NODE_OPTIONS=--require /app/data/patch.js`.

This session retires that hack at the code layer:
- New `SPORT_MARKETS` map alongside `SPORT_KEYS` — separate lists
  per sport, all frozen with `Object.freeze`. NBA + NCAAB share
  basketball markets; WNBA is basketball minus PRA (odds-api
  doesn't carry that for WNBA); MLB sends batter + pitcher markets;
  every soccer league shares the soccer set.
- `fetchEventOddsFromApi(sportKey, eventId, apiKey, sport)` —
  third arg added; reads `getMarketsForSport(sport)` instead of
  the union. Backwards-compatible: omitted sport falls back to
  NBA (safe default).
- `fetchAllOdds(sport, apiKey)` — already had the local sport key;
  now passes it through.

**Coolify follow-up**: after this deploy, the operator can drop
`NODE_OPTIONS=--require /app/data/patch.js` from the web service
env and delete `/app/data/patch.js`. The runtime patch is now
dead code.

### Phase 2 — Live hero prop

`web/src/app/api/hero-prop/route.ts` (new) — picks one fresh real
prop from today's NBA → WNBA → MLB cascade and grades it. Two-stage
flow: GET `/api/odds/{sport}` → POST `/api/analyze/prop`. Both
calls share a 6s AbortController timeout. Server-side cached for
15 minutes via `Cache-Control: s-maxage=900`. Falls back to a
static Jokic example (`isStatic: true`) when every sport is empty
so the landing page never blanks out.

`web/src/components/LiveHeroProp.tsx` (new) — replaces the
hard-coded `FloatingDemoCard` inside `Hero.tsx`. Renders the live
prop with:
- "LIVE" badge with a pulsing green dot
- Sport-colored category tag (NBA red, WNBA orange, MLB blue, soccer green)
- Player name + line + projection + edge **visible** (hook)
- Grade letter + confidence **visible** via GradePill (proof)
- Reasoning section **blurred** with backdrop `blur(4px)`, a
  scan-line gradient (`repeating-linear-gradient`), a bottom-fade
  mask, and a "CLASSIFIED · Sign up to unlock" label (paywall)
- Single CTA: "Sign up to read the full analysis →"

While loading OR when the API returns `isStatic: true`, renders
the original Jokic mockup byte-for-byte. No flash-of-blank-card.

`Hero.tsx` — old `FloatingDemoCard`, `Stat`, and `row` constant
deleted. `GradePill` import moved into `LiveHeroProp`.

### Phase 3 — Soccer weather

`soccerFeatureExtractor.js` now calls `weatherService.getWeather()`
for outdoor WC venues after resolving the venue. Dome venues skip
the fetch. Unknown venues skip silently. New feature fields:
`weather_temp_f`, `weather_wind_mph`, `weather_wind_dir`,
`weather_precip_mm`. All null when skipped/failed.

### Phase 4/5 — OG tags + CSP (mostly already done)

OG meta + Twitter card + `og-image.png` were all wired in Session 9.
Existing CSP in `next.config.ts` was comprehensive. Session 16 added:
- `https://browser.sentry-cdn.com` to `script-src` (Sentry SDK)
- `https://*.sentry.io` and `https://*.ingest.sentry.io` to
  `connect-src` (event ingestion). Without these the browser
  Sentry client silently dropped events.

### Tests added (Session 16)
| Suite                                  | Tests |
|----------------------------------------|-------|
| `tests/unit/sportMarkets.test.js`      | 16    |
| `tests/unit/soccerWeather.test.js`     | 7     |
| **Session 16 total**                   | **23**|

### Quality gates
- `npm test`: **1429 / 1429 passing** (1405 + 24), 110 suites, 0 regressions
- `web/npm run build`: clean
- License audit: third-party deps remain permissive

### Honest gaps
- `LiveHeroProp`'s glitch effect (scan lines + blur + fade) renders
  only in a browser. Build verified. Deploy smoke-test recommended.
- Hero endpoint depends on `/api/odds/{sport}` returning populated
  `props`. If upstream odds-api is rate-limited or proxies aren't
  reaching Express, the static fallback fires — cold visitors see
  the Jokic mockup, not live data.
- Sentry CSP entries added but require redeploy to take effect.
  Until then, the browser SDK silently drops events.

### Coolify follow-ups
1. **Drop the patch.js workaround**: remove
   `NODE_OPTIONS=--require /app/data/patch.js` from the web
   service env. Code-layer fix in Session 16 makes the runtime
   patch obsolete.

---

## Session 15 (2026-06-11) — SHIPPED

### Phase 0 — Correctness

- **Africa short-circuit removed** (`Pricing.tsx:152`). The Session 14
  backend handles 'africa' end-to-end: validation accepts it; missing
  `STRIPE_PRICE_AFRICA` returns a 503 with `code:'tier_unconfigured'`
  the existing inline error surface displays. The frontend short-
  circuit was blocking checkout even after the backend was ready.
- **Odds + Sentry + welcome email audits**: all already correct from
  prior sessions. Documented for posterity; no fixes required.
- **Poller → odds pipeline**: confirmed there's NO key-mismatch
  pipeline issue. Pollers handle game resolution
  (`game:{id}:status`, `poller:{SPORT}:heartbeat`); `oddsService`
  populates `odds:{sport}:{date}` on-demand. The "1 games shown but
  Slate empty" report would be a separate odds-api quota / key issue.
- **Founder price fallback hardened**. `PRICE_MAP` no longer falls
  back to fake strings like `'price_analyst_monthly'` that would 400
  from Stripe in live mode. Missing env → `PRICE_UNCONFIGURED`
  sentinel → 503 with `code:'tier_unconfigured'`. Founder codes
  presented against an unwired founder-price env now fall back
  GRACEFULLY to the standard tier price rather than dropping the
  checkout — the founder discount is operator-controlled and
  shouldn't break the user's purchase.

### Phase 1 — Signal audit

Documented in a new comment block at the top of
`src/services/intelligence/computeFeatures.js`. Every signal cited
to its data source: injury (ESPN injury feed), coach (Supabase
`coach_profiles` + JSON seed), consistency (game logs via
`gameLogService`), Tank01 fields (Session 14 + 15 prefetch),
soccer cascade (Session 9), park factors (Session 15 — static),
weather (Session 15 — Open-Meteo), pace factors (Session 15 —
static). No phantom signals.

### Phase 2 — MLB park factors

`src/data/parkFactors.js` — all 30 MLB parks indexed to 100 league
average. FanGraphs 2024-25 three-year weighted data. Coors at hr=128,
SF Oracle at hr=85 (the two extremes by design). `getParkFactor()`
returns null on unknown teams so the feature extractor drops the
signal cleanly rather than falsely reporting "neutral".

Wired into `computeFeatures.js` MLB branch — features pick up
`park_hr`, `park_h`, `park_r`, `park_home` when the home team
resolves.

### Phase 3 — Weather (Open-Meteo)

`src/services/weatherService.js` — Open-Meteo proxy (no API key
required). 5-second hard timeout, 1-hour Redis cache, silent
degrade on failure (never blocks the grade). Fahrenheit + mph units
to match the bettors' mental model.

`src/data/venueCoordinates.js` — lat/lon + dome flag for all 30
MLB venues and all 16 World Cup 2026 venues. Retractable stadiums
are marked `dome:true` because operators close the roof when
conditions warrant — weather doesn't drive grade in that case.

Wired into `computeFeatures.js` MLB branch — fetches weather when
the home venue is outdoor + has finite coordinates.

### Phase 4 — Tank01 daily prefetch

`scripts/tank01-prefetch.js` — orchestrator that pulls the Redis
cache keys Session 14's `tank01Augment.js` reads. Default budget
≤80 requests/run, configurable via `--max=N`. NBA path pulls
schedule + final-game box scores + daily odds. MLB path pulls
scoreboard + final-game box scores (BvP pull awaits batter/pitcher
ID resolution on the scoreboard payload).

Recommended trigger: extend the n8n "Morning Ops" workflow to
exec the script daily at 7am UTC.

### Phase 5 — MLB matchup context

`src/services/intelligence/mlbContext.js` — pure functions for
platoonAdvantage(pitcherHand, batterHand) and
projectedPA(lineupPosition). Tested with all hand combinations +
all lineup slots. Wiring into computeFeatures is deferred until
odds-api carries those fields (it doesn't today).

### Phase 6 — NBA pace factors

`src/data/paceFactors.js` — all 30 NBA teams (NBA.com/stats 2024-25,
indexed to 100). Legacy-abbreviation aliases (NJN→BKN, NOH→NOP,
SEA→OKC, CHO→CHA) so historical lookups resolve. Wired into the NBA
branch of `computeFeatures.js` — `pace_factor` (player's team) +
`opp_pace_factor` (opponent).

### Tests added (Session 15)
| Suite                                  | Tests |
|----------------------------------------|-------|
| `tests/unit/parkFactors.test.js`       | 14    |
| `tests/unit/weatherService.test.js`    | 14    |
| `tests/unit/tank01Prefetch.test.js`    | 14    |
| `tests/unit/mlbContext.test.js`        | 21    |
| `tests/unit/paceFactors.test.js`       | 12    |
| **Session 15 total**                   | **75** |

### Quality gates
- `npm test`: **1405 / 1405 passing** (1330 + 75 new), 108 suites,
  0 regressions. One pre-existing computeFeatures test was updated:
  the contract used to be "ESPN failure → empty features"; the
  contract is now "ESPN failure → static context augmentation
  (pace, park) still surfaces."
- `web/npm run build`: clean
- License audit: third-party deps remain permissive

### Honest gaps
- Tank01 prefetch must be triggered by n8n/cron before the augmentor
  reads return data. Grades work as before until then.
- BvP pull is no-op until probable-pitcher IDs land on the Tank01
  MLB scoreboard projection.
- Phase 5 helpers tested but not wired — odds-api doesn't carry
  batter handedness or lineup position fields today.
- Weather for soccer venues: only MLB is wired this session.
  Soccer venue weather is a 5-line follow-up in the soccer extractor.

### Coolify env (Session 15 additions)
None new from this session.

---

## Session 14 (2026-06-11) — SHIPPED

### Phase 1 — Africa tier checkout

- `src/services/stripeService.js` — `PRICE_MAP.africa` added (reads
  `STRIPE_PRICE_AFRICA`, null when unset). `getPriceId('africa')`
  returns the new `PRICE_UNCONFIGURED` sentinel when the env var
  isn't set. `createCheckoutSession` translates the sentinel to a
  503 with `code: 'tier_unconfigured'` so the frontend can render a
  helpful message instead of a generic failure.
- `src/routes/stripe.js` — validation whitelist extended:
  `['africa', 'analyst', 'desk']`. The catch block recognizes
  `err.code === 'tier_unconfigured'` and surfaces it cleanly.
- Tests: +6 (3 integration around `/api/stripe/checkout` for the
  africa tier, 3 unit around `getPriceId('africa')` and the
  exported sentinel).
- **DB CHECK constraint blocker from Session 12 still applies** —
  Stripe webhook writes of `tier='africa'` to `users.tier` /
  `user_profiles.tier` will 23514 until the manual SQL drops + re-
  adds the constraint with 'africa' included. Validation-layer fix
  is in place; the migration is the next step.

### Phase 2 + 3 — Tank01 NBA + MLB wired into computeFeatures

Architectural choice: cache-read path only on the user request
path. The Tank01 adapters (Session 9) already wrap their primitives
behind Redis with TTL'd `tank01:*` keys. The new
`src/services/intelligence/tank01Augment.js` reads those keys
directly without ever calling RapidAPI — that keeps the user
request path off the 1000/mo free-tier budget. A daily prefetch
(future session) will populate the keys; until then the augmentor
returns empty objects and the existing ESPN-derived features stand
alone.

- `augmentNbaFeatures({gameId, playerName, ymd})` reads
  `tank01:nba:boxscore:{gameId}` and `tank01:nba:odds:{ymd}`,
  surfaces `t01_pts/reb/ast/threes/blk/stl/tov/minutes/_final` for
  the named player when present, plus a `t01_market_present`
  marker when daily odds are cached.
- `augmentMlbFeatures({gameId, batterName, batterId, pitcherId,
  pitcherName, ymd})` reads `tank01:mlb:bvp:{batterId}:{pitcherId}`
  and surfaces BvP signals (`t01_bvp_pa/ab/h/hr/so` + derived
  `t01_bvp_so_rate`). Best-effort fallbacks: name-only markers when
  IDs are absent (future ID resolution), daily-scoreboard presence
  marker when pitcher is unknown.
- `computeFeatures.js` calls both augmentors after `safeGetFeatures`
  and merges the result with `Object.assign`. Wrapped in try/catch
  so a Redis hiccup never poisons a grade.
- Tests: 13 new in `tests/unit/tank01Augment.test.js`. Existing
  computeFeatures + soccerBranch suites still green (no
  regressions).

### Phase 4 — WNBA + MLB odds proxies

- `oddsService.SPORT_KEYS` — added `wnba: 'basketball_wnba'` and
  `mlb: 'baseball_mlb'`. Off-season odds-api responses return empty
  arrays which the Slate handles cleanly.
- `src/routes/odds.js` — new `buildSportRoute()` factory drives
  `/api/odds/wnba` and `/api/odds/mlb` (clones of the existing
  `/api/odds/nba` handler).
- Next.js proxies: `web/src/app/api/odds/{nba,wnba,mlb}/route.ts`
  (the NBA one was also missing — Slate had been pointing at a
  non-existent route).
- `Slate.tsx` `FETCH_URLS` — WNBA + MLB no longer flagged as
  unsupported. ALL tab fans out to all four sports via
  `Promise.allSettled`.

### Phase 5 — UX polish

- `web/src/components/OAuthIcons.tsx` — inline SVGs for Google G,
  Apple silhouette, X glyph. ~1 KB each, no icon library import.
- Login + signup pages wire icons into the OAuth buttons with a
  shared layout helper.
- Slate loading state — bare "Loading the slate…" text replaced
  with three shimmer-skeleton placeholder cards approximating
  GameCard dimensions. `@keyframes vyndr-shimmer` added to
  `globals.css` so other loading surfaces can reuse the animation.
- Empty state messaging — the Slate's empty-result case already
  shows a "Scan it manually →" CTA from Session 13; Session 14
  preserves that path.
- Mobile nav — added a subtle "Scan manually →" tertiary link in
  the mobile hamburger panel. The desktop nav stays clean (the
  Slate IS the scan surface there).

### Tests added (Session 14)
| Suite                                  | Tests |
|----------------------------------------|-------|
| `tests/unit/tank01Augment.test.js`     | 13    |
| `tests/integration/stripe.test.js` extended (Africa checkout) | +3 |
| `tests/unit/stripeService.test.js` extended (Africa getPriceId) | +3 |
| **Session 14 total**                   | **19** |

### Quality gates
- `npm test`: **1330 / 1330 passing** (1311 + 19), 103 suites, 0 regressions
- `web/npm run build`: clean — all four odds proxies prerender
- License audit: third-party deps remain permissive

### Honest gaps
- Tank01 cache keys are not yet populated by any prefetch — the
  augmentor wiring is in place but reads will miss until a daily
  prefetch script lands. The augmentor returns `{}` on miss, so
  grades work exactly as before until the keys populate.
- Africa-tier writes to users.tier will still 23514 (CHECK
  violation) post-checkout. The DB constraint migration remains a
  manual SQL step from Session 12.
- `STRIPE_PRICE_AFRICA` env var is not set in Coolify yet. Until
  it is, `/api/stripe/checkout` returns 503 with
  `code: 'tier_unconfigured'` for `tier:'africa'`.
- WNBA odds: odds-api may not always carry props during off-season.
  Slate degrades cleanly (empty `props` array + empty state UX).
- OAuth: Google works (if Supabase Site URL + Redirect URLs are
  configured). Apple + X buttons render with their icons but the
  redirect won't succeed until provider configuration lands in the
  Supabase dashboard (Apple Developer Service ID + key; X OAuth
  2.0 client).

### Coolify env (Session 14 additions)

```
# New, required to unblock Africa checkout end-to-end:
STRIPE_PRICE_AFRICA=price_...   # After creating the product in Stripe dashboard
```

---

## Session 13 (2026-06-11) — SHIPPED

### Phase 1 — Africa geo-restriction via CF-IPCountry

The Session 12 Africa tier was visible to anyone on a Swahili locale
(too narrow: most African users browse in English/French; too broad:
Swahili speakers anywhere got the discount). Session 13 swaps the
locale proxy for real Cloudflare IP geolocation.

- **`web/middleware.ts`** — reads `cf-ipcountry` (uppercase),
  stamps `x-vyndr-country` on the request alongside the locale header.
  Empty string when traffic bypasses Cloudflare (local dev).
- **`web/src/lib/locales.ts`** — `AFRICAN_COUNTRIES` set covering all
  54 sovereign African nations (NG/KE/ZA/GH + sub-Saharan + MENA
  overlap). `isAfricanCountry(code)` is case-insensitive and degrades
  closed on empty/null inputs.
- **`LocaleContext`** — extended with `country`/`inAfrica` fields;
  new `useRegion()` hook for components that gate by geography.
- **`Pricing.tsx`** — `inAfrica === false` filters the Africa tier
  out of the render entirely. `inAfrica === true` puts it first.
  Locale-based reorder removed.
- **Pricing grid CSS** — desktop column count now tracks the visible
  tier count via a `--pricing-cols` CSS custom property on the grid
  root (3 outside Africa, 4 inside). Sidesteps a styled-jsx
  limitation with attribute selectors inside `:global()`.

### Phase 2 — OAuth: Google + Apple + X

- **`AuthContext`** — added generic `signInWithProvider(provider)`
  alongside the legacy `signInWithGoogle()` (kept as an alias so
  existing callers don't break). Translates Supabase OAuth errors
  into a flat `{ error: string }` so the UI can surface a friendly
  inline message when a provider isn't configured.
- **`login/page.tsx` + `signup/page.tsx`** — both pages now render
  three OAuth buttons (Google, Apple, X). The `handleOAuth` helper
  routes to `signInWithProvider` and shows an inline error when the
  provider isn't configured ("apple login isn't available yet. Use
  email or another method.").
- **External configuration required** (operator action, not code):
  - Supabase Auth → Providers → Apple: needs an Apple Developer
    Service ID + private key
  - Supabase Auth → Providers → Twitter: needs an X Developer OAuth 2.0
    client
  - Google should already work — if it doesn't, verify Supabase
    Auth → URL Configuration → Site URL = https://vyndr.app and
    Redirect URLs include `https://vyndr.app/**`, and that the Google
    Cloud Console OAuth consent screen has the Supabase callback URL
    in Authorized redirect URIs.

### Phase 3 — The Slate (browse-first dashboard)

Generalizes the Session 8 `/soccer` page pattern across every sport.

- **`web/src/components/PropRow.tsx`** — single-prop UI with three
  states (ungraded/grading/graded). Pure presentational — parent
  owns the API call so there's one shared rate-limited grading queue.
  Free-tier expansion shows blurred reasoning + Unlock CTA; paid tier
  shows full reasoning + kill conditions. Exports `propRowKey()` for
  stable Map keys.
- **`web/src/components/GameCard.tsx`** — game header + expandable
  prop list. Sport emoji prefix (🏀 NBA/WNBA, ⚾ MLB, ⚽ soccer),
  sport-accented left border, formatted local game time, `+ N more`
  expander when props > defaultVisible.
- **`web/src/components/Slate.tsx`** — the orchestrator. Sport tabs
  (ALL / NBA / WNBA / MLB / Soccer), sticky search input, group-by-game
  pipeline, `gradedProps` Map, single-flight grading queue
  (`gradingKey`). `Promise.allSettled` fan-out for the ALL tab so a
  single sport failing doesn't blank the slate. `FETCH_URLS` is
  null-aware — sports without an odds proxy yet (WNBA, MLB) render a
  bottom-of-page "endpoint not configured yet" note rather than
  spamming 404s.
- **Search filter + manual-scan fallback** — sticky search filters
  game cards by team name and prop rows by player/stat. Empty result
  shows a CTA linking to `/scan?q=<query>` so users land on a
  partially-filled scan form.
- **`/dashboard`** — `<Slate />` mounted as the lead surface above
  the existing Top Graded / Most Parlayed / Recent Reads sections.
  Those sections stay as supplementary intelligence layers — not
  removed.
- **`Nav.tsx`** — "Scan" link removed from primary nav. The Slate is
  the scan surface; `/scan` stays reachable from the slate's
  empty-state CTA.

### Tests added
| Suite                                  | Tests |
|----------------------------------------|-------|
| `tests/unit/africaCountries.test.js`   | 6     |
| **Session 13 total**                   | **6** |

### Quality gates
- `npm test`: **1311 / 1311 passing** (1305 + 6 new), 102 suites, 0 regressions
- `web/npm run build`: clean — Slate page + components prerender
- License audit: third-party deps remain permissive

### Honest gaps (documented, not bugs)
- I could not visually verify The Slate in a browser. Build/type
  correctness is confirmed; "renders correctly with live odds data"
  needs a deploy smoke test.
- Google/Apple/X OAuth: button wiring is complete. Whether the
  buttons actually authenticate depends on external dashboard
  configuration (Supabase + Google Cloud Console + Apple Developer +
  X Developer Portal). Apple and X are guaranteed to show the
  "isn't available yet" inline error until configured.
- WNBA + MLB don't have `/api/odds/*` proxies on the Next.js side
  yet. The Slate degrades cleanly (footer note), but those tabs
  return empty until the proxies exist. Session-14 work.
- Africa tier still can't be SOLD even when geo gates open it —
  the Stripe price + the DB CHECK migration remain outstanding from
  Session 12.

### Coolify env (Session 13 additions)
None. CF-IPCountry is set by Cloudflare automatically; no env-var
change required.

---

## Session 12 (2026-06-11) — SHIPPED

### FIX 1 — i18n infrastructure (10 languages, cookie-based)

Honest scope decision: skipped the full `[locale]/` URL-prefix
refactor (would have touched all 24+ pages). Went cookie-based +
header-stamping middleware instead — same UX, much smaller blast
radius. URL-prefix routing can layer on later without breaking
anything.

- **`web/src/lib/locales.ts`** — locale registry. 10 locales:
  en (source), es, fr, pt, ar (RTL), sw, hi, ja, ko, zh.
  `LOCALE_META` carries native names + dir + region.
  `AFRICA_LOCALES = {sw}` used by the pricing reorder logic.
- **`web/src/middleware.ts`** — locale resolver. Priority: URL
  prefix → `NEXT_LOCALE` cookie → `Accept-Language` parsing →
  default 'en'. Stamps `x-vyndr-locale` on the request so server
  components can read it via `next/headers`.
- **`web/src/locales/{en,es,fr,pt,ar,sw,hi,ja,ko,zh}.json`** —
  10 translation dictionaries, each ~17 keys covering nav, slate,
  grade, pricing, sports, auth, common, cookie. Every file declares
  its `_meta.review_status`: `en` is `source`, the other 9 are
  `translated_unreviewed`. Sports terminology is locale-correct
  (Fútbol/Football/サッカー/كرة القدم/Soka, etc.).
- **`web/src/lib/i18n.ts`** — synchronous server-side loader
  (`getTranslations(locale) → {t, locale, dir}`) plus
  `getServerTranslations()` which reads the middleware-stamped
  header. English fallback per key, falls to the key string itself
  when missing on both. `{name}` interpolation supported.
- **`web/src/contexts/LocaleContext.tsx`** — client provider +
  `useT()` / `useLocale()` hooks. Mounted in the root layout above
  every other provider.
- **RTL** — `<html dir="rtl">` set in root layout when locale is
  Arabic. `globals.css` flips nav direction and isolates monospace
  blocks (numbers stay LTR — financial data convention).
- **`LocaleSwitcher.tsx`** — compact mono dropdown with native
  language names. Sets the cookie, reloads the page. Mounted in Nav
  for both authenticated and anonymous states.
- **Wired into**: Nav (5 links + login button), CookieConsent
  (message + accept + privacy link), Pricing (CTAs translate per
  tier). High-impact components first; longer-tail strings remain
  English with `t('key')` calls scheduled for a follow-up.

### FIX 2 — Africa tier ($4.99/mo)

- **`src/config/tiers.js`** — adds the `africa` tier between free
  and analyst: 10 scans/day, reasoning_visible:true,
  kill_conditions_detail:true, alerts:false, api_access:false.
  Frozen.
- **Scan-limit middleware** — no change needed. `scanLimit()` reads
  via `getScanLimit()`, which now resolves 'africa' to 10.
- **`web/src/components/Pricing.tsx`** — adds the VYNDR Africa
  card. The pricing-grid CSS unfolds from 2-up (tablet) to 4-up
  (≥1100px desktop). When the user's locale is Swahili (a proxy
  for African markets — IP-based geolocation deferred to a future
  session), the Africa tier renders FIRST.
- **Honest UX gap**: Africa-tier checkout short-circuits to an
  inline "coming soon" message instead of triggering Stripe. Two
  reasons: (a) the backend `/api/stripe/checkout` route validates
  tier against `['analyst','desk']` and the spec forbids backend
  edits this session; (b) `STRIPE_PRICE_AFRICA` is unset and the
  Stripe product hasn't been created in the dashboard yet.
- **DB CHECK constraint blocker**: migrations 001 + 011 declare
  `tier IN ('free','analyst','desk')`. The webhook will 23514
  (check_violation) if it tries to write `africa` until the
  constraint is extended. Documented in `tiers.js` header + in
  SYSTEM-MANIFEST. Out of scope this session per the no-migration
  rule.
- **`.env.example`** — `STRIPE_PRICE_AFRICA=price_...` placeholder
  with explanatory comment.

### Tests added (Session 12)
| Suite                              | Tests |
|------------------------------------|-------|
| `tests/unit/i18n.test.js`          | 14    |
| `tests/unit/tiers.test.js` (extended) | +5 |
| **Total new**                      | **19** |

### Quality gates
- `npm test`: **1305 / 1305 passing** (1286 + 19), 101 suites, 0 regressions
- `web/npm run build`: clean. NOTE — every page is now `ƒ Dynamic`
  rather than `○ Static` because the root layout reads request
  headers (`next/headers`) for locale resolution. This is the
  expected cost of SSR i18n. If FCP regresses, the fallback is
  client-side cookie reads (brief English flash on first paint, but
  static prerender returns).
- License audit: third-party deps remain permissive (no new licenses
  introduced — translation files are JSON in our own repo).

### Open items / follow-ups
1. **DB CHECK constraint** must be updated before the Africa tier
   can actually be assigned to users. Manual SQL:
   ```
   ALTER TABLE users DROP CONSTRAINT users_tier_check;
   ALTER TABLE users ADD CONSTRAINT users_tier_check
     CHECK (tier IN ('free','africa','analyst','desk'));
   -- same for user_profiles
   ```
2. **Stripe product** for VYNDR Africa not created. Manual step:
   create the product + price in the Stripe dashboard, set
   `STRIPE_PRICE_AFRICA` in Coolify, then extend the backend
   checkout route's validation list.
3. **Translation review** — only `en` is `source` quality. The
   other 9 locales are `translated_unreviewed`. Native-speaker
   review recommended for Arabic, Chinese, Korean, Japanese, Hindi
   before public launch.
4. **Browser geolocation** — Africa tier currently sorts first only
   for Swahili-locale users. IP-based detection (NG/KE/ZA/GH/etc.)
   would catch English-speaking African users; deferred to a
   session with proper geo middleware (Cloudflare headers, etc.).
5. **Per-page meta translations** — page `<title>` and OG tags are
   still English. Adding per-locale metadata requires the
   `[locale]/` segment refactor, deferred.

### Coolify env (Session 12 additions)

```
# Already required:
NEXT_LOCALE         # No env — set as a per-user cookie by the switcher.

# New, optional:
STRIPE_PRICE_AFRICA=price_...   # Once you create the Stripe product
```

---

## Session 10 (2026-06-10) — SHIPPED

### FIX 1 — Internal auth refactor + /pipeline off-host support

Pre-audit revealed the spec's premise was wrong: `/api/grading/pipeline`
and `/api/grading/resolve` ALREADY EXISTED with `requireInternal`
middleware inline in each route file. The actual n8n bug was a header-
name mismatch (n8n sends `x-internal-key`, code read
`X-VYNDR-Internal-Key`) PLUS a hard loopback-IP check that blocks any
caller from a separate container.

- **`src/middleware/internalAuth.js`** (new) — centralized middleware.
  Accepts BOTH `x-internal-key` (Session 10 short form, n8n) AND
  `X-VYNDR-Internal-Key` (legacy, poller + existing tests). Timing-safe
  string compare. `loopbackOnly` is now an OPT-IN flag (default off).
- **`src/routes/grading.js`** — replaced inline `requireInternal` with
  the centralized middleware. `/resolve` uses `{loopbackOnly: true}`
  (poller from localhost). `/pipeline` uses the off-host variant
  (n8n from a separate container). `__helpers.requireInternal` kept
  exported for the existing test suite — backwards compatible.
- **`src/routes/corrections.js`** — same refactor; `/correct` stays
  loopback-only (morning sweep is co-located).
- **`/api/grading/pipeline`** body shape — empty body now iterates
  `nba/wnba/mlb` (n8n's "Morning Ops" workflow case). Single-sport
  body still works and returns the legacy summary object so existing
  per-sport tests continue to pass.

### FIX 2 — Soccer prefetch cascade keys

Session 9's adapters write to `apifootball:*` and `footapi:*` cache
keys; the daily prefetch was still only writing `soccer:*` (the
tertiary fallback). The cascade in `soccerFeatureExtractor` never
hit PRIMARY because nothing populated those keys.

- **`scripts/soccer-data-prefetch.js`** — new `enrichFromApiFootball()`
  walks finished WC fixtures via `apiFootballAdapter.getFixtures` +
  `getFixturePlayerStats`, aggregates per-player season stats across
  matches (minutes, goals, assists, shots, tackles, cards, rating),
  collapses to per-90 rates, and writes
  `apifootball:player_by_name:{normalizedName}` (24h TTL). Hard-capped
  at `--max-players=80` per run.
- **CLI flags added** — `--source=api-football|footapi|football-data|all`
  (default `all`), `--max-players=N`, `--season=N`. Existing `--leagues`
  and `--dry-run` flags unchanged.
- **`enrichRefereesFromFootApi()`** — best-effort referee enrichment.
  Writes `footapi:referee_by_name:{name}` (7d TTL).
- **Behavior preserved** — legacy `soccer:player:*` writes still happen
  when `football-data` source is selected (and it's the default in
  `all` mode). The cascade resolves at PRIMARY when api-football data
  is available, TERTIARY otherwise.
- **Boot guard relaxed** — previously bailed when
  `FOOTBALL_DATA_API_KEY` was unset; now bails only when EVERY source
  is unavailable. The script can run on api-football alone.

### FIX 3 — Sentry error tracking

- **`src/utils/sentry.js`** (new) — graceful no-op when `SENTRY_DSN`
  is unset (every Sentry surface becomes a noop). Initialized at the
  top of `src/app.js` BEFORE express is required.
- **`Sentry.setupExpressErrorHandler(app)`** mounted AFTER all routes
  in `app.js` — catches uncaught route errors automatically.
- **PII scrubbing** — `beforeSend` strips `user.ip_address`,
  `user.email`, `request.cookies`, `request.headers.authorization`,
  `request.headers.cookie`, and BOTH internal-key headers. Bearer
  tokens never reach Sentry.
- **Sampling** — 10% traces, 100% errors. Free-tier friendly.
- **Frontend** — manual init via `web/src/components/SentryInit.tsx`
  (client component, mounted in root layout). Lazy `import('@sentry/nextjs')`
  fires on mount only if `NEXT_PUBLIC_SENTRY_DSN` is set. Avoids the
  `withSentryConfig` plugin which conflicts with standalone output
  mode (per Session 10 spec note).

### FIX 4 — Welcome email on signup

The `sendWelcomeEmail` function in `web/src/services/email.ts` already
existed; nobody called it.

- **Copy updated** — 5/month → 3/day, NexaPay → Stripe founder pricing
  ($14.99/mo locked for life), added the soccer/World Cup mention per
  Session 10 spec. Both HTML and plain-text variants.
- **`web/src/app/api/welcome-email/route.ts`** (new) — POST endpoint,
  bearer-auth required. Reads Supabase `user_metadata` via the
  service-role admin client, checks `welcome_email_sent`, sends if
  absent, sets the flag. Idempotent — re-trigger is a cheap noop.
  **No migration needed** — `user_metadata` is the Supabase auth
  user's existing JSONB scratchpad.
- **Trigger** — `web/src/app/welcome/page.tsx` fires the POST once on
  mount via `useRef` guard. Server-side idempotency keeps it safe
  across refreshes too.
- **Graceful failure** — if `RESEND_API_KEY` is unset, send returns
  `{ ok: false }` but the flag is still set (manual operator override
  if a batch needs re-sending).

### Tests added

| Suite                                                  | Tests |
|--------------------------------------------------------|-------|
| `tests/unit/internalAuth.test.js`                      | 15    |
| `tests/unit/soccerDataPrefetchCascade.test.js`         | 20    |
| `tests/unit/sentry.test.js`                            | 10    |
| Existing suites (pipeline, resolution, prefetch) re-verified | 0 new |
| **Session 10 total**                                   | **45+** |

### Quality gates
- `npm test`: **1286 / 1286 passing** (1240 + 46 new), 100 suites, 0 regressions
- `web/npm run build`: clean — Sentry mount + `/api/welcome-email` prerender
- License audit: only permissive licenses (Sentry adds nothing exotic)

### Env vars to set in Coolify

```
# Already required from prior sessions:
VYNDR_INTERNAL_KEY=<existing — header is now x-internal-key OR X-VYNDR-Internal-Key>
RESEND_API_KEY=<existing>
RESEND_FROM_EMAIL=<existing, defaults to "VYNDR <grades@vyndr.app>">

# New in Session 10 (all optional — wrappers degrade gracefully):
SENTRY_DSN=<from sentry.io project settings>
NEXT_PUBLIC_SENTRY_DSN=<same DSN — needs the NEXT_PUBLIC_ prefix to reach browser bundle>
```

### Open items
- Soccer prefetch hasn't run against live api-football yet — first
  cron tick after deploy will populate the cascade. Until then, the
  feature extractor resolves at tertiary (football-data).
- Sentry's frontend manual-init pattern means errors before the React
  tree mounts (e.g. SSR errors) bypass Sentry. The backend handler
  catches Express-side errors; for browser-side SSR errors we'd need
  `instrumentation.ts`, deferred.
- Welcome email idempotency relies on Supabase `user_metadata`. If a
  user signs in via SSO and never lands on `/welcome`, they don't get
  the email. Acceptable Day-1 — track via PostHog if it becomes a
  real conversion gap.

## Session 9 (2026-06-10) — SHIPPED

World Cup opens tomorrow. This session closed three live-site
emergencies (404, OOM cycle, slow FCP), added three new soccer data
sources with a priority cascade, two new RapidAPI sports adapters, a
real grace-period downgrade middleware, and updated the legal pages.

### Phase 0 — critical fixes

- **`/pricing` 404 → fixed.** `web/src/app/pricing/page.tsx` created;
  wraps the existing `Pricing` component on a standalone route so
  email renewal CTAs (which link to `/pricing` via
  `web/src/services/email.ts:204`) no longer land on 404. Metadata
  block ships with OG + Twitter tags.
- **Web container OOM cycle → cause identified, fix documented.**
  `docker logs` on the live host (z2zyki…-032334469519, 44 restarts
  and climbing) returned `FATAL ERROR: Reached heap limit Allocation
  failed - JavaScript heap out of memory`. Docker mem limit is
  unlimited (0) — this is Node's own ~2 GB V8 default. Fix is a
  Coolify env-var change: **`NODE_OPTIONS=--max-old-space-size=4096`**
  on the web container. Cannot be applied from this session — listed
  under the Coolify env requirements at the end of this entry.
- **7.5s FCP → root cause traced to the OOM cycle.** All page routes
  are static-prerendered; root layout makes no blocking calls. The
  FCP measurement is dominated by cold-start latency hit during each
  restart. The NODE_OPTIONS fix is the primary FCP fix too — re-measure
  after deploy.

### Phase 1 — soccer source upgrade

New adapter cascade for soccer (priority order):

1. **api-football.com (PRIMARY)** — `src/services/adapters/apiFootballAdapter.js`.
   100 req/day soft limit (90, with 10-req safety margin). 6 endpoints:
   `getFixtures`, `getFixtureLineups`, `getFixturePlayerStats`,
   `getFixtureEvents`, `getPlayerSeasonStats`, `getStandings`. Auth via
   `x-apisports-key` header (NOT RapidAPI). Per-endpoint TTLs match
   data volatility (fixtures 6h, lineups/playerstats 24h, events 12h).
2. **FootApi via RapidAPI (BACKUP)** — `src/services/adapters/footApiAdapter.js`.
   50 req/day (soft 45). 4 endpoints: `getMatchLineups` (28 stat keys),
   `getMatchIncidents` (minute + addedTime), `getRefereeStatistics`
   (yellow/red per game), `getWorldCupSchedule` (tournament ID 16).
3. **football-data.org (TERTIARY)** — existing Session 7j adapter unchanged.

The `soccerFeatureExtractor` now cascades through these via a new
`loadFromCascade()` helper. Each load returns a `_source` tag so
debugging is straightforward; `meta.sources` exposes the
attribution per lookup (`player`, `nextMatch`, `lastFixture`,
`referee`). Existing 17 soccer-extractor tests still pass; 7 new
cascade tests prove the priority order.

### Phase 1 — Tank01 RapidAPI adapters

- **`tank01NbaAdapter.js`** — live NBA box scores, schedule, betting
  odds. Status-aware TTL: 5-min cache while a game is in-progress,
  24-hour cache once it reports Final. Free tier 1,000 req/mo;
  TTL-bound rather than counter-bound.
- **`tank01MlbAdapter.js`** — live MLB box scores, daily scoreboard,
  and **batter-vs-pitcher** (the headline new MLB signal — a batter's
  historical PA/AB/H/HR/SO line against a specific pitcher). Same
  status-aware TTL pattern as NBA.

Both Tank01 adapters use the shared `RAPID_API_KEY` (also used by
FootApi). Host overridable via `TANK01_NBA_HOST` / `TANK01_MLB_HOST`.

### Phase 2 — production readiness

- **Grace-period downgrade middleware** — `src/middleware/gracePeriod.js`.
  Fires at request time on tier-gated routes (`/api/scan/parlay`,
  `/api/alerts`, `/api/props/joint-history`). Reads
  `req.user.grace_period_until` (now selected by `requireAuth` in
  `src/middleware/auth.js`), and on expiry atomically downgrades
  `users.tier` and `user_profiles.tier` to `'free'`, clears the
  timestamp, sets `subscription_status='expired'` on the profile
  mirror, and rewrites `req.user` so the route immediately sees the
  downgrade. Closes the long-standing "cancelled users keep paid
  access forever" gap. **Ordering matters**: grace must run AFTER
  requireAuth and BEFORE scanLimit, because scanLimit reads tier off
  req.user — a just-expired Desk user would otherwise burn one final
  unlimited-quota request.
- **TOS update** — `web/src/app/terms/page.tsx` Subscription Terms
  switched from NexaPay to Stripe; Acceptable Use now explicitly
  states "VYNDR does NOT offer API access at any tier" — closes the
  Session 7h immutable.
- **Privacy update** — `web/src/app/privacy/page.tsx` Payment Data
  section switched from NexaPay to Stripe with specifics on what
  Stripe receives. New "Sub-processors" section explicitly lists
  Stripe, Supabase, PostHog, Resend.
- **Cookie consent banner** — `web/src/components/CookieConsent.tsx`,
  mounted in root layout. Thin bottom bar, SSR-safe (renders nothing
  until client mount checks localStorage), single-button accept,
  links to Privacy Policy.
- **Root layout metadata** — keywords + description extended to
  include soccer and World Cup 2026 intelligence terms. OG + Twitter
  cards already comprehensive from prior sessions. Per-page metadata
  for /soccer + /scan deferred (those pages are `'use client'`; would
  need server-component wrappers — cosmetic).

### Tests added

| Suite                                          | Tests |
|------------------------------------------------|-------|
| `tests/unit/apiFootballAdapter.test.js`        | 16    |
| `tests/unit/footApiAdapter.test.js`            | 13    |
| `tests/unit/soccerFeatureExtractorCascade.test.js` | 7  |
| `tests/unit/tank01NbaAdapter.test.js`          | 12    |
| `tests/unit/tank01MlbAdapter.test.js`          | 12    |
| `tests/unit/gracePeriod.test.js`               | 7     |
| **Session 9 total**                            | **67** |

### Quality gates
- `npm test`: **1240 / 1240 passing** (1173 baseline + 67 new), 97 suites, 0 regressions
- `web/npm run build`: clean — `/pricing` + everything else prerenders, no type errors
- License audit: only permissive licenses

### Coolify env vars (apply on the web container — keys not in repo)

```
NODE_OPTIONS=--max-old-space-size=4096        # fixes the OOM cycle
API_FOOTBALL_KEY=<from api-sports.io>          # PRIMARY soccer source
FOOTBALL_DATA_API_KEY=<from football-data.org> # TERTIARY soccer source
RAPID_API_KEY=<from RapidAPI marketplace>      # FootApi + Tank01 NBA + Tank01 MLB
FOOTAPI_HOST=footapi7.p.rapidapi.com           # default — override only for mirrors
TANK01_NBA_HOST=tank01-fantasy-stats.p.rapidapi.com
TANK01_MLB_HOST=tank01-mlb-live-in-game-real-time-statistics.p.rapidapi.com
```

### Open items
- `NODE_OPTIONS` must be set in Coolify before the next deploy; until
  then, the web container will keep OOM-looping. This is the single
  most important production action item.
- The 2 GB+ heap usage that triggered the OOM suggests a memory leak
  in the Next.js standalone server. Heap-snapshot investigation
  deferred — the env-var bump buys headroom but doesn't fix the leak
  root cause.
- Per-page OG metadata on `/soccer` and `/scan` requires those pages
  to be refactored to a server-component wrapper pattern. Not blocking.
- The new adapter cascade improves data quality WHEN
  `API_FOOTBALL_KEY` / `RAPID_API_KEY` are populated and a daily
  prefetch has run against them. Until then, the cascade silently
  falls through to football-data.org and static reference data.
  Updating `scripts/soccer-data-prefetch.js` to write the new
  `apifootball:*` / `footapi:*` cache keys is a follow-up.

---

## Session 8 (2026-06-10) — SHIPPED

Frontend layer that connects users to the Session 7h–7j backend.
NexaPay → Stripe cutover on the pricing flow + a `/soccer` page that
exposes the soccer intelligence pipeline.

### Files created (frontend)
- `web/src/app/api/odds/soccer/[league]/route.ts` — Next.js proxy →
  Express `GET /api/odds/soccer/:league`. Validates league against the
  9 accepted codes upstream so a typo bounces at the Next boundary.
- `web/src/app/soccer/page.tsx` — live soccer odds feed. Hosts
  `SportSelector`, fetches `/api/odds/soccer/:league`, groups props by
  match → stat type. "Grade" button triggers inline scan via
  `/api/scan` (sport: Soccer) and renders the result through
  `SoccerGradeResult`. Soccer-only page; switching the selector to
  another sport bounces to `/scan`.
- `web/src/app/upgrade/success/page.tsx` — Stripe success landing.
  Reads `session_id`, refreshes AuthContext so the new tier flips
  immediately. Does NOT verify against Stripe from the client (no
  secret key on the browser) — the webhook is the source of truth.
- `web/src/app/upgrade/cancel/page.tsx` — Stripe cancel landing.
- `web/src/components/SportSelector.tsx` — pill tabs (NBA/WNBA/MLB/
  Soccer); Soccer reveals a sub-row of the 9 league codes matching
  Express's `SOCCER_SPORT_KEYS`. Emits `{ sport, league? }` via
  `onChange` — pure UI, no fetches.
- `web/src/components/SoccerGradeResult.tsx` — soccer-themed result
  card. Parses the engine's reasoning summary into visual chips
  (⚽ goals/90, 📊 xG, 🎯 penalty taker, 🏹 free-kick taker, ⛳ corner
  taker, 🏔️ altitude, 🟨 referee, ⏱️ minutes discount, 🛡️ opponent
  defense, 🏆 tournament pedigree). Color-coded by tone
  (positive / caution / warning / neutral). Free-tier responses
  (carrying `tier_gated: true`) render the chip row blurred under an
  upgrade CTA; the structured grade + confidence + edge stay visible.
  Kept separate from `GradeCard` so the NBA/MLB/WNBA path is
  untouched.

### Files modified (frontend)
- `web/src/app/api/checkout/route.ts` — full rewrite. Was a NexaPay
  payment-link creator; is now a thin proxy that forwards `{ tier,
  founder_code? }` + bearer to Express `/api/stripe/checkout`.
  Response remap: `checkout_url` → `url` for callsite compat; both
  fields shipped so either reads cleanly.
- `web/src/app/api/scan/route.ts` — accepts `Soccer` sport in addition
  to NBA/MLB/WNBA. Soccer stat-type allowlist mirrors the backend
  `VALID_STAT_TYPES` (goals, shots_on_target, shots, tackles, cards,
  corners, saves, goals_conceded, passes, clean_sheet, assists).
- `web/src/components/Pricing.tsx` — CTAs converted from `<a href>` to
  onClick handlers. Uses `useAuth()` for the bearer token, POSTs to
  `/api/checkout`, `window.location.assign` to the returned Stripe URL.
  Loading state on the active tier, inline error banner. Anonymous
  visitors bounce to `/signup?return=/%23pricing`. Footnote rewritten
  from "NexaPay" to "Stripe (test mode while we onboard founders)".
- `web/src/components/Nav.tsx` — small BETA tag next to the wordmark.
  Glitch-styled, monospace, low-opacity green border. Renders on every
  page that mounts Nav.

### Files modified (backend — ONE allowed change)
- `src/services/stripeService.js` — `success_url` / `cancel_url`
  point at the frontend (`NEXT_PUBLIC_SITE_URL` with `BASE_URL`
  fallback, default `http://localhost:3000`). Previously the routes
  pointed at the Express origin which would have 404'd the redirect.
  New URLs:
    - `${frontendUrl}/upgrade/success?session_id={CHECKOUT_SESSION_ID}`
    - `${frontendUrl}/upgrade/cancel`
  All 23 Stripe tests still pass (none asserted on the URL strings).

### Files modified (docs)
- `docs/SYSTEM-MANIFEST.md` — `/api/odds/soccer/[league]` row in
  Next.js routes, new section listing the three new Next.js pages,
  the Session 7h "dual-provider divergence" callout flipped from
  open-work to ✅ complete.
- `BUILD-STATE.md` — Session 8 entry.

### Honest verification status

Build-verified (passed `web/npm run build` after every component):
- All TypeScript types resolve
- All routes prerender / build correctly (24 pages, 30+ API routes)
- No ESLint errors

NOT runtime-verified in this session (I have no browser to click
through):
- Actual Stripe checkout redirect end-to-end (test mode card flow)
- Soccer odds rendering with live data (depends on
  `FOOTBALL_DATA_API_KEY` being set in prod and the daily prefetch
  having run)
- SoccerGradeResult signal parsing against a real engine response
  (signal-chip regex tested against the exact phrasing
  `buildSoccerReasoningLines` emits in `analyzeViaEngine1.js`, but
  not against live engine output)
- AuthContext.refresh() actually triggering a profile re-read after
  the Stripe redirect

These are the expected next-session sanity checks once Coolify
deploys this build.

### Quality gates
- `npm test` (backend): **1173 / 1173 passing**, 91 suites, 0 regressions
  from Session 7j baseline
- `web/npm run build`: clean — all new routes prerendered, no type errors
- License audit: only permissive licenses

## Session 7j (2026-06-10) — SHIPPED

Permanent soccer sport vertical, launching with FIFA World Cup 2026
(opens June 11). League-agnostic architecture supports WC, EPL, La Liga,
Bundesliga, Serie A, Ligue 1, UCL, MLS, Liga MX from the same code paths.

### Files created
- `src/data/worldcup2026.js` — 16 venues + altitudes + climate, CONCACAF
  + CONMEBOL teams, penalty/corner/free-kick takers (top 25 teams),
  tournament players (≥3 career WC goals). All frozen. Helpers:
  `isPenaltyTaker`, `isCornerTaker`, `isFreeKickTaker`,
  `getTournamentHistory`, `isHomeContinent`, `getVenue`, `altitudeImpact`.
- `src/services/adapters/footballDataAdapter.js` — football-data.org v4
  REST adapter. 8/min token bucket (2-req safety margin vs the 10/min
  upstream cap). Tier-matched Redis TTLs (fixtures 6h, standings 12h,
  squads 24h, scorers 6h). Stale-while-revalidate fallback when the
  bucket is drained or the API 5xx's. Returns null when no API key —
  callers degrade gracefully.
- `src/services/intelligence/soccerFeatureExtractor.js` — reads from
  prefetch-populated Redis cache (NEVER hits external APIs on the
  user request path). Builds the engine1 feature vector + a soccer
  overlay (goals_per_90, xG, penalty/corner/FK role, altitude,
  referee, tournament history, rest_days).
- `poller/soccer.js` — league-agnostic fixture poller. WC pulls from
  the rezarahiminia/worldcup2026 OSS API (no rate limit) and falls
  back to football-data.org. Other leagues use the adapter directly.
  Writes `soccer:nextmatch:{team}` (24h TTL) + `soccer:lastfixture:{team}`
  (7d TTL) per fixture. Self-rescheduling: 5-min ticks during live
  matches, 30-min otherwise. PM2-managed.
- `scripts/soccer-data-prefetch.js` — daily batch job. Pulls standings
  + scorers per configured league, computes per-team defensive
  aggregate (`goals_conceded_per_game`, `defensive_rank_norm` on a 0..1
  scale that slots into engine1's `opp_rank_stat`) and per-player
  per-90 rates. Writes `soccer:teamdefense:{league}:{team}` and
  `soccer:player:{normalizedName}`. `--leagues=WC,PL --dry-run` flags
  supported. xG fields left null on Day 1 (soccerdata-Python bridge is
  a follow-up; engine handles nulls gracefully).
- `tests/unit/worldcup2026.test.js` (20 tests)
- `tests/unit/footballDataAdapter.test.js` (15 tests)
- `tests/unit/soccerFeatureExtractor.test.js` (17 tests)
- `tests/unit/trapDetectionSoccer.test.js` (21 tests)
- `tests/unit/computeFeaturesSoccerBranch.test.js` (4 tests)
- `tests/unit/analyzeViaEngine1Soccer.test.js` (8 tests)
- `tests/unit/soccerPoller.test.js` (22 tests)
- `tests/unit/soccerDataPrefetch.test.js` (14 tests)
- `tests/integration/oddsSoccer.test.js` (6 tests)

### Files modified
- `src/utils/oddsNormalizer.js` — `MARKET_MAP` gains 10 soccer market
  keys (`player_goals`, `player_shots_on_target`, etc → `goals`,
  `shots_on_target`, etc). Existing NBA mappings untouched.
- `src/routes/analyze.js`, `src/routes/scan.js` — `VALID_STAT_TYPES`
  set extended with 10 soccer stat types. `'assists'` is shared with
  NBA; `sport` field discriminates downstream.
- `src/routes/odds.js` — new `GET /api/odds/soccer/:league` route.
  Validates league against `SOCCER_SPORT_KEYS` (9 leagues), surfaces
  405 valid-list hint on miss.
- `src/services/oddsService.js` — `SPORT_KEYS` gains 9 soccer entries
  mapping `soccer_wc` → `soccer_fifa_world_cup`, `soccer_epl` →
  `soccer_epl`, etc. `SOCCER_SPORT_KEYS` exported as a frozen list.
- `src/services/intelligence/computeFeatures.js` — `sport ∈
  {'soccer','football'}` dispatches to `extractSoccerFeatures`. NBA
  path unchanged.
- `src/services/intelligence/trapDetection.js` — six soccer signals
  (xg_regression, altitude_risk, rotation_risk, minute_discount,
  referee_card_bias [positive — excluded from composite],
  strong_defense). `getTrapScore` branches on `input.sport`.
- `src/services/intelligence/analyzeViaEngine1.js` — soccer reasoning
  branch (`buildSoccerReasoningLines`). Uses "matches" not "games",
  surfaces xG / penalty taker / altitude / referee / minutes / WC
  pedigree. NBA-specific sentences (back-to-back, injury report)
  guarded by `!isSoccer`.
- `poller/ecosystem.config.js` — `poller-soccer` PM2 app added. Same
  restart policy as box-score pollers; `SOCCER_LEAGUES` env wired.
- `.env.example` — soccer block (`FOOTBALL_DATA_API_KEY`,
  `SOCCER_LEAGUES`, `WORLDCUP_API_URL`, `RAPID_API_KEY`).
- `docs/SYSTEM-MANIFEST.md` — `/api/odds/soccer/:league` row in §2,
  Soccer env block in §3, soccer poller in poller-set, four new
  external API rows in §6, `[ARCH-3]` soccer-pipeline note in §8.

### Quality gates (all green)
- `npm test`: **1173 / 1173 passing** (1042 baseline + 131 new soccer
  tests across 9 new suites), 91 suites, 0 failures
- `web/npm run build`: clean
- License audit: only permissive third-party licenses

## Session 7i (2026-06-10) — SHIPPED

### Stripe checkout + webhook (no new routes — gap-fill on existing)

Pre-audit revealed Session 3.4 already shipped a fuller Stripe
integration than this session's spec asked for: route, sig verify,
all 4 event handlers with 48h grace, customer create + persist,
portal + status endpoints, founder-code system, and `users` ↔
`user_profiles` dual writes. Raw-body middleware was already correctly
positioned at `src/app.js:52` (before global `express.json()`).

What this session added on top:
- `tests/integration/stripe.test.js` — refactored stripe mock to a
  singleton handle, then added two route-level tests:
  1. `constructEvent` throws → route returns 400 with `{ error: /signature/i }`
  2. valid signature → route dispatches to `handleWebhookEvent` and returns `{ received: true }`
- `tests/unit/stripeService.test.js` — added `customer.subscription.updated`
  test covering portal-driven plan-change: maps `items.data[0].price.id`
  back to a tier via `PRICE_MAP`, writes to both `users` + `user_profiles`,
  clears grace.
- `docs/SYSTEM-MANIFEST.md` — appended a *Payments: dual-provider divergence*
  subsection under § 8 Findings → Frontend ↔ Backend contract, documenting
  that the Next.js `/api/checkout` still routes to NexaPay while Express
  Stripe is wired but uncalled by the frontend, with a 4-step cutover
  punch list for a follow-up session.

### Quality gates (all green)
- `npm test`: **1042 / 1042 passing** (delta +3 from 1039 baseline, 0 regressions)
- `web/npm run build`: clean
- License audit: third-party deps only permissive (MIT/Apache-2.0/BSD/ISC/MPL/BlueOak/CC-BY/0BSD)
- `curl https://api.vyndr.app/api/health` → `{"status":"healthy"}`

---

## Session 7h (2026-06-10) — SHIPPED

### Stripe (test mode)
Resources created against `sk_test_*` via direct REST API (Stripe MCP plugin OAuth flow was non-functional in this environment; bypassed by hitting `https://api.stripe.com/v1` with the secret key in a single shell subprocess, then shredding the on-disk key file).

- `prod_UgBel9RYTROCxr` — VYNDR (`metadata.tier=analyst`)
  - `price_1TgpGxIp1Mec3r2E6Wh6oeaP` — $14.99/mo recurring (`metadata.tier=analyst`)
- `prod_UgBeSBYw2j9oXL` — VYNDR Desk (`metadata.tier=desk`)
  - `price_1TgpGyIp1Mec3r2EQq50KKhF` — $44.99/mo recurring (`metadata.tier=desk`)
- `we_1TgpGzIp1Mec3r2ERtDIF2n2` — webhook → `https://api.vyndr.app/api/stripe/webhook`
  - Subscribed events: `checkout.session.completed`, `customer.subscription.updated`, `customer.subscription.deleted`, `invoice.payment_failed`
  - Signing secret saved to `~/.stripe-webhook-secret` (chmod 600) — read once, paste into Coolify, then `shred -u`.

### Tier infrastructure
- `src/config/tiers.js` — frozen access matrix (`free` / `analyst` / `desk`); `api_access:false` on every tier (non-negotiable consumer-product invariant)
- `src/middleware/scanLimit.js` — 24h rolling per-user/IP quota (free=3, analyst=15, desk=∞); 429 + `Retry-After` + `X-Scans-Used/Limit` headers on overflow; in-memory LRU with `MAX_TRACKED=50_000`
- `src/utils/tierGating.js` — pure response gating; free tier keeps grade/confidence/edge_pct, redacts `reasoning` + `kill_conditions_triggered`; paid tiers pass through
- Wired into `src/routes/scan.js` (`/parlay` after `requireAuth`) and `src/routes/analyze.js` (`/prop` + `/batch`, gating applied per-result)

### SQL (run manually in Supabase SQL Editor)
- `docs/sql/pricing_slots.sql` — creates `pricing_slots` table + RLS + price IDs seeded. Not added to the migrations chain per session policy.

### Tests
- `tests/unit/tiers.test.js` (10 tests) — frozen matrix, `api_access=false` invariant, fallback behavior
- `tests/unit/tierGating.test.js` (9 tests) — free-tier redaction, paid passthrough, no input mutation
- `tests/unit/scanLimit.test.js` (10 tests) — per-tier limits, anonymous IP fallback, independent quotas, desk skip
- Existing suites adapted for the new middleware: `tests/unit/analyzeCache.test.js`, `tests/integration/analyze.test.js`, `tests/integration/scan.test.js` reset the scan-limit map in `beforeEach`; the integration suite for `/api/analyze` mocks `applyTierGating` as pass-through so engine-shape assertions stay focused on the engine contract (gating has its own suite).

### Quality gates (all green)
- `npm test`: **1039 / 1039 passing**, 82 suites, 0 failures
- `web/npm run build`: production build clean, all 24 routes prerendered
- License audit: only permissive third-party licenses (MIT/Apache-2.0/BSD/ISC/etc.); single UNLICENSED entry is our own `vyndr-web` workspace

## Web Tier v6 (2026-05-18) — SHIPPED
Complete frontend overhaul. 18 pages, 22 API routes. `npm run build` passes with zero errors.

### New pages
- `/dashboard` — post-login slate (sport tabs, top grades, tonight's games, most parlayed, recent scans, first-time onboarding)
- `/game/[id]` — game preview with spread/total/ML, starting lineups with injury flags, expandable prop list, add-to-parlay
- `/profile` — tier status, subscription state, founder badge, cancel-at-period-end flow
- `/intelligence` — Desk-tier timeline of evolution/coaching/cascade/ABS/line-movement signals (blurred for non-Desk)
- `/terms`, `/privacy`, `/responsible-gambling` — branded legal pages with brand voice
- `/scan` — full rebuild (sport tabs, real /api/scan with tier gating, parlay tray hook)
- `/login`, `/signup` — wired to Supabase Auth via AuthContext (Google OAuth + email/password + age check)
- `/marketplace` — coming-soon waitlist (API access, custom alerts, capsule drop)
- `/ledger`, `/tracker` — design system refresh, accuracy buckets, miss autopsy, quick-slip
- `/` — auth-aware: logged-in users redirect to `/dashboard`; anonymous see marketing

### New API routes
- `/api/games/tonight`, `/api/games/[id]`, `/api/games/[id]/props`
- `/api/props/top-graded`, `/api/props/most-parlayed`
- `/api/players/search`
- `/api/user/recent-scans`
- `/api/intelligence/feed`
- `/api/parlay/add-leg`, `/api/parlay/grade`
- `/api/ledger`, `/api/ledger/accuracy`
- All cached via Supabase `odds_cache` table (5-min TTL) — never hit Odds API directly

### Services + middleware
- `services/odds-cache.ts` — Supabase-backed TTL cache for upstream calls (loader + stale-fallback)
- `services/email.ts` — Resend wrapper: `sendWelcomeEmail`, `sendPaymentReceipt`, `sendRenewalReminder`
- `middleware/rateLimit.ts` — per-tier per-minute scan throttle (5/30/60 free/analyst/desk)
- `services/nexapay.ts` — already shipped (createPaymentLink + HMAC webhook verify), now wired to email receipts

### Components
- `GradeCard.tsx` — premium grade card with tier-gated blur (factors locked for free; alt-lines locked for non-Desk)
- `ParlayContext.tsx` + `ParlayTray.tsx` — cross-page parlay state, slide-up tray, /api/parlay/grade integration
- `BottomTabBar.tsx` — mobile-only 5-tab navigation (Home/Scan/Parlay/Ledger/Profile) with parlay badge
- `ShareCard.tsx` — canvas-rendered 1200x630 OG share image with grade letter; download + copy-to-clipboard
- `Nav.tsx`, `Hero.tsx`, `LivePropsStrip.tsx`, `Features.tsx`, `Pricing.tsx`, `HowItWorks.tsx`, `FAQ.tsx`, `Footer.tsx` — design system refresh already shipped

### PWA + meta
- `public/manifest.json` (192/512/maskable icons)
- `public/icons/icon-{192,512,maskable-512}.png`, `apple-touch-icon.png`, `favicon.ico`, `favicon.png`
- `public/og-image.png` — 1200x630 social share card
- `appleWebApp` + `manifest` + theme-color wired in `layout.tsx`

### Supabase migrations
- `011_user_profiles_web.sql` (already deployed): `user_profiles` (+RLS+trigger), `parlay_leg_frequency` (+RPC), `scan_history`
- `012_web_caching_waitlist.sql` (NEW): `odds_cache` (TTL cache), `waitlist_signups`, `founder_pricing_seats` view, `prune_expired_odds_cache()` helper

### Backend
- `src/app.js` — CORS middleware added (localhost dev + vyndr.app + *.vercel.app + FRONTEND_ORIGINS env var)
- `package.json` — added `cors@2.8.5`

### Bug fixes
- Scan page sibling-div JSX bug fixed (rewritten from scratch)
- Lockfile warning silenced via `next.config.ts` `turbopack.root` (already in place)
- Auth callback rewritten to use Supabase JS session API instead of raw localStorage parse

- Built complete dual-sport grading engine from vyndr-SHIP.md spec
- 187 new tests (544 total), all green across 38 test suites
- **Phase 1 — Infrastructure:**
  - Flask app.py with blueprints, health check, rate limiting (60/min default, 20/min grade), flask-cors, /api/docs
  - evolutionEngine.py moved to blueprints/evolution.py (structural only — logic unchanged)
  - utils: retry.py, data_warehouse.py (game-day TTL), bayesian.py (per-stat-type weights, skewness, data sufficiency curve), edge_calculator.py (real edge + quarter-Kelly), context_aggregator.py (15 factors), similarity.py (min 0.7), regime_detector.py (disabled <20 games), blind_spot_detector.py (worst 5%), supabase_client.py
  - Data files: park_factors.json (30 parks, lat/lng, roof_status), reporter_database.json (80+ handles), timezone_map.json (30 arenas), grade_thresholds.json, odds_api_config.json
  - requirements.txt with all 15 dependencies
  - Cold start boot sequence with reporter seeding
- **Phase 2 — Data Sources:**
  - blueprints/synergy.py (team play types, matchup, tracking, defensive scheme)
  - blueprints/nba_context.py (teammate impact, game script, home/road, rest/travel, matchup pace, foul trouble, B2B stat-specific, positional defense, usage-efficiency, playoff modifiers, NBA sub-scores endpoint)
  - blueprints/lineup_intelligence.py (3-source architecture, reporter trust tiers, tweet parsing, two-stage grading, reporter-line correlation)
  - blueprints/odds_scanner.py (free tier 2 pulls/day, odds warehouse, line movement detection, slate scanner)
  - utils/weather.py (Open-Meteo, continuous 30min, dome detection, regrade triggers)
  - utils/archetypes.py (5 pitcher dimensions, 5 batter dimensions, 6 NBA dimensions — ALL with weight_profiles, batting order, batter approach, pitcher identity, weight blending)
  - schemeClassifier.js enhanced: Synergy-first with regex fallback, backward compatible
- **Phase 3 — Grading Engines:**
  - blueprints/mlb.py (14-step pipeline, pitcher/batter profiles, ABS challenge system with player-specific discipline score, TTO decay, platoon-specific opponent quality, lineup protection, day/night, bullpen state, catcher framing)
  - blueprints/image_grade.py (OCR pipeline with low-confidence confirmation)
  - utils/sportsbooks.py (10 books, parlay grading with correlation check, phi coefficient)
  - utils/capper.py (pick numbers, breaking alerts, daily recap, miss autopsy)
- **Phase 4 — Self-Improving Loop:**
  - blueprints/resolution.py (nightly job: actuals from nba_api/MLB-StatsAPI, hit/miss, CLV, alignment, joint outcomes, calibration triggers)
  - blueprints/calibration.py (point-biserial weights, global offset, Brier score, blind spots, CLV/alignment reports)
- **Phase 5 — Database + Tests:**
  - Migration 005: lineup_scheme_data
  - Migration 006: nba_data_cache, mlb_data_cache, grade_outcomes (ALL ship columns incl discipline_score, CLV, alignment), player_calibrated_weights
  - Migration 007: lineup_updates, reporter_trust (with source_type + starting_trust), odds_warehouse, ship_line_movements, reporter_line_correlation, api_health_log, global_calibration, ship_joint_outcomes
  - 5 new test files covering infrastructure, grading engine, data sources, resolution pipeline, scheme classifier enhancement
- **Key Spec Compliance:**
  - Grade thresholds LOCKED (A+ through F)
  - SHADOW_MODE = True (first 2 weeks)
  - Bayesian weights are INITIAL ESTIMATES (marked as such)
  - Abstention check BEFORE data cap
  - Point-biserial bounds 0.05-0.50, global offset ±0.15
  - Real edge with vig + quarter-Kelly
  - Brier + CLV from day one
  - Capper A- and above ONLY
  - ABS is CHALLENGE system (successful challenges don't deplete)
  - Foul trouble widens std, not mean
  - Stat-specific B2B adjustments
  - Matchup-specific pace (home 60/40)
  - Positional defense (tracking > roster position)
  - Usage-efficiency tradeoff (-1.5% TS per +5% usage)
  - Tier limits documented but NOT enforced (gate manually later)
  - Node.js stays Node.js, Python is data/utility layer via HTTP

### Session 10c — 2026-04-13 (FINAL INTEGRATION PATCH)
- Applied 15-item integration patch — wiring + features + infrastructure
- 35 new tests (644 total), all green across 40 test suites
- **Wiring (items 1-5):**
  - Scratch → redistribution → re-grade → alt line scan → alert chain in lineup_intelligence.py
  - Slate scan → alt line auto-scan for A-grades in odds_scanner.py
  - Nightly resolution steps 14-18: coaching update, player-out history, evolution scan, unconventional data collection, monthly validation
  - Migration 009: supplement columns on grade_outcomes (coaching_context, redistribution_context, evolution_flag, alt_line_opportunity, unconventional_factors) + unconventional_factor_data table
  - API docs updated with 7 supplement endpoints

### Session 10d — 2026-04-13 (SECURITY AUDIT)
- Applied 19-item security hardening pass — Ryan Montgomery panel reviewed
- 45 new tests (689 total), all green across 41 test suites
- **Authentication (items 1, 8, 11):**
  - utils/auth.py: require_auth (JWT with issuer check) + require_service_role (BETONBLK_INTERNAL_KEY)
  - PyJWT added to requirements.txt
  - BETONBLK_INTERNAL_KEY separates cron auth from service key — service key never leaves Railway
- **Input Security (items 3, 10, 13):**
  - utils/validation.py: whitelist stat types, sanitize strings (strip SQL/HTML), validate line 0-500, image upload (magic bytes, 10MB max, PNG/JPEG/GIF), parlay legs 2-12
  - OCR rate limit 3/min, max 2 concurrent
  - MAX_CONTENT_LENGTH 1MB globally, 413 JSON response
- **Network Security (items 2, 12):**
  - CORS locked to ALLOWED_ORIGINS env var (no more wildcard)
  - Real IP from X-Forwarded-For for rate limiter and security logger
- **Error Handling (item 9):**
  - Production returns generic "Internal server error" — no stack traces
  - 404, 405, 413, 429 all return JSON
- **Monitoring (items 4, 5, 6, 15, 17, 18):**
  - Security headers: X-Frame-Options DENY, HSTS, CSP, nosniff, XSS protection, Server removed
  - utils/security_logger.py: request logging, rate tracking, SQL injection detection, security_events table
  - utils/env_check.py: startup validation, exits on missing required vars, never logs secrets
  - security-scan.yml: weekly pip-audit + npm audit
  - security.txt: /.well-known/security.txt with contact
  - 90-day security event retention cleanup + weekly security digest (50+ events per IP = action required)
- **Infrastructure (items 7, 14, 16, 19):**
  - Migration 010: security_events table with RLS
  - Supabase client timeout guidance, retry with 30s default timeout
  - Source code secret scan test (sk_live_, eyJhbGci, sbp_)
  - .gitignore: .env, .env.local, .env.production, *.pem, *.key, .vercel/

### Session 10b — 2026-04-13 (SUPPLEMENT BUILD)
- Built 5 intelligence supplement systems — ADDITIVE, no existing code modified
- 65 new tests (609 total), all green across 39 test suites
- **System 1 — Coaching Tendency Database:**
  - blueprints/coaching.py (NEW) — per-coach NBA + MLB tendencies, nightly update from game logs, shift detection (15%+ threshold on last 15 vs season baseline)
  - 12 NBA fields (pace, 3PT rate, ISO freq, PnR usage, rotation depth, late-game player, score-state lineups, second-unit patterns, redistribution profile, shot location, timeout tendency)
  - 10 MLB fields (starter hook, quick hook, bullpen philosophy, IBB rate, PH freq, bunts, closer-only, platoon, lineup consistency, challenge aggressiveness)
- **System 2 — Usage Redistribution Engine:**
  - blueprints/redistribution.py (NEW) — two-layer calculation (Layer A: minutes redistribution from historical player-out data + coaching rotation depth; Layer B: offensive system change from archetype shifts)
  - Uses coaching database, applies usage-efficiency tradeoff (-1.5% TS per +5% usage)
  - Three tiers: primary (>=0.20 boost, >=0.75 confidence), secondary (>=0.10, >=0.60), tertiary (>=0.05)
  - Auto-grades at 15%+ boost / 0.65+ confidence, formats 60-second absorption alerts
- **System 3 — Alt Line Scanner:**
  - Added to existing odds_scanner.py — auto-runs on A-grade props after slate scan
  - Pulls alt lines from odds_warehouse, calculates model probability via Bayesian norm_cdf
  - Real edge with vig on each alt, finds optimal (best EV/dollar)
  - Only recommends if alt edge exceeds standard by 3%+
- **System 4 — Unconventional Data Pipeline:**
  - blueprints/unconventional.py (NEW) — validation gate for non-traditional correlates
  - 500 instance minimum, Pearson r > 0.15, Bonferroni-corrected p-value
  - 5 tracked factors: altitude, contract year, referee crew history, travel distance (pre-validated), arena altitude
  - Factors only enter grading engine AFTER passing validation
- **System 5 — Player Evolution Alerting:**
  - Added to existing evolution.py — daily scan across multiple metrics simultaneously
  - NBA: usage_rate, assist_rate, three_pa_rate, fg_pct, minutes
  - MLB: k_rate, bb_rate, exit_velocity, hard_hit_pct, fb_velo
  - PLAYER_EVOLUTION_DETECTED when 2+ metrics show concurrent inflection (10%+ change, 15 game minimum)
  - Timestamped records in evolution_detections table, Evolution Watch content formatter
- **Migration 008:** coaching_tendencies, player_out_history, evolution_detections, unconventional_validations (all with indexes + RLS)
- **Integration:** 3 new blueprints registered in app.py (coaching_bp, redistribution_bp, unconventional_bp), evolution + odds_scanner extended with new endpoints
