Fixes the three DESIGN-SPEC Part 4 + #17 audit findings.
1. React #418 hydration mismatch (landing → dashboard entry). The
`maybeSignedIn` value was computed in a useState INITIALIZER that reads
localStorage during render: server (no window) → false → emits the
marketing tree; a signed-in visitor's first CLIENT render → true → emits
the loading placeholder. Whole-subtree server/client mismatch → React
discarded and re-rendered the page. Deferred behind a mounted flag so the
first client render matches the server; the stored-session check flips
post-mount. SSR HTML is no longer discarded.
2. Loading walls → skeletons. New tokenized Skeleton primitive
(.vyndr-skeleton, reduced-motion-safe via the global rule). Swapped into
every text-wall loader: dashboard slate load ("Loading the slate…"), /desk
("Assembling the pack…"), /ledger ("Loading…"), scan ("Loading the model…"),
and the landing redirect placeholder. No bare text loader remains.
3. scan→ledger persistence. Root cause: the scan page read its bearer token
from localStorage['sb-token'] — a key written ONLY by the OAuth callback —
so email/password users posted /api/scan anonymously and the ledger write
(gated on an authed user) was silently skipped. Now uses the authoritative
session.access_token (matching the ledger read path). Extracted the row
builder to web/src/lib/ledgerRow.js (shared, testable).
Tests: +17 (scanLedgerPersistence write→mine round-trip + scope + idempotency;
ds1SpeedTrust hydration/skeleton/persistence source invariants). Full suite
233 suites / 2793 green; web build exit 0.

- specs/ROW-GRAMMAR.md: the row grammar law (slot order, color law, mark
law, mobile stacking, no-truncation), locked by tests/unit/rowGrammar.
StatStrip violations fixed: MovementChip before the grade (market
context before model output); ViabilityChips after the archetype
(identity is one contiguous run).
- Line-movement sparklines: intradayRefreshService.trackHistory captures
real {t,line} points per grade (seeded with the lock, deduped when
flat, capped 24) inside the snapshot write-back; StatStrip.LineSparkline
renders at >=3 points (green toward / amber against / dim flat).
- Last-10 dot strips: services/last10Dots (streaksService accessors) ->
/api/snapshot/:sport attaches last10_dots from rosterlogs:{sport};
StatStrip.DotStrip renders vs the LOCKED line, newest first.
- CLV distribution: getModelAggregate emits clv_distribution (7 signed
buckets, outliers clamped) only past the centralized n>=20 gate;
ledger MODEL header renders the bar strip.
- Global search: SearchModal (cmd-K via GlobalHosts + window.__search),
players via /api/players/search per sport + static lib/teams.js
(soccer deliberately absent); Nav search icon + Search first in the
mobile More sheet. Explore tab untouched.
- Landing LCP: fade-up floored at opacity .6 (hero h1 contentful on
first frame, S33 visible-floor rule) + IBM Plex Mono preload:false
(4 decorative font files off the slow-4G critical path).
2654 -> 2698 tests (226 suites) green; web build exit 0.

5.1 Archetype defined on-page: one line from the archetype library under
ARCHETYPE DNA (BOMBER — elite raw power…); expander keeps the long form.
5.2 VYNDR-on-team live: getModelAggregate team scope (migration-020 column)
+ /api/ledger/model?team= + ModelRecord mounted on the Team Hub header.
5.3 WNBA/NBA profile parity: minutes-based usage (+MIN season cell) when
the feed carries minutes — absent beats invented.
5.4 Settings read meter: real rolling-24h usage from the SAME store the
limiter enforces (GET /api/user/scan-meter + proxy). Metered tiers see
'X of N reads today' + bar; unlimited tiers see nothing. Corrects the
stale '5 scans / month' copy.
5.5 Per-tier calibration on the MODEL tab: A+/A/B/C chips with hit% at
n>=20 PER TIER, 'building (n/20)' below — the separation between tiers
is the proof the grades mean something.

ledger_entries is live (migration 019 applied to prod, RLS + NULLS NOT
DISTINCT dedupe verified against the real database). Every grade now
persists, settles against the real result, and carries closing-line value.
- ledgerService: pipeline pre-grade upserts (public model record, user_id
null, idempotent), closing capture on every snapshot (last write before
game start = the close), settlement with SIGNED CLV (over = locked -
closing; beat/faded/flat), 30d model aggregate with the hard n>=20 rule.
- Write paths: snapshotService -> ledger (priority path); Next /api/scan ->
ledger for authenticated users only (anon never touches the public
record). Refused reads write nothing and don't burn a scan.
- Honest refusal (work-order 1.5): no projection => insufficient_data,
grade null, "INSUFFICIENT DATA - no read" UI. The web gradeAdapter no
longer displays the line as the model projection (the audit's
model==line / +0% edge degenerate); the card renders absent states.
projectionFor is sport-aware (l5 -> l20 -> {stat}_per_90 -> xG).
- /ledger: MY READS | MODEL tabs; model header shows hit% + beat-close%
only at n>=20, else RECORD BUILDING + live pending count. ModelRecord
deferred-render strip on landing + player hero. CLV + outcome chips,
revised_from_grade strikethrough (Phase 2.5 ready).
- SYNC (Task 5): thresholds vs SNAPSHOT_EXPECTED_INTERVAL (normal <1.5x,
amber >=1.5x, STALE red >=3x) via /api/snapshot/summary.
- Phase 2.5 logged in specs/vyndr-roadmap.md (build after Phase 3).
- Data-semantics hardening: strict null-safe numeric parsing everywhere a
market value is handled (Number(null)===0 would have fabricated lines).
Backend 2309 -> 2327 tests (201 suites), web build exit 0.
