Session 32: Grades pipeline + NFL/NHL wiring + rate limiting + audit cleanup (1718 tests)

- gradeSlateService writes grades:{sport} cache (closes content pipeline →
  dataLevel full); fire-and-forget from oddsService.recordDownstream, gated
  by shouldGradeSlate (off in test, GRADE_SLATE_ON_FETCH override)
- NFL/NHL wired: oddsService SPORT_KEYS/SPORT_MARKETS (correct the-odds-api
  keys americanfootball_nfl/icehockey_nhl), proplineAdapter MARKETS, NHL
  MARKET_MAP keys to avoid silent-zero
- rate limiting mounted on 8 public cached routers (odds/parlay 30/min,
  rest 60/min)
- jsonlLogger writes to temp under test (no more dirtied tracked artifact);
  5MB pipeline test given 20s timeout

 ## Current Phase
-AUDIT v31.0 — Full code audit + security review + cleanup (Session 31)
+SHIP BUILD v32.0 — Close audit gaps: grades pipeline + NFL/NHL wiring +
+rate limiting + test-artifact cleanup (Session 32)
+
+## 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.

+## Grades Content Pipeline (Session 32)
+Closes the content pipeline: `contentTemplateService` reads a `grades:{sport}`
+cache "when present" but nothing wrote it, so slate/POTD never reached
+`dataLevel: 'full'`.
+- **Writer** — `gradeSlateService.gradeAndCacheSlate(sport, props, opts)`

+- **Trigger** — fire-and-forget inside `oddsService.recordDownstream` (runs

+
+## NFL/NHL Props (Session 32)
+NFL + NHL wired end-to-end. **the-odds-api keys are `americanfootball_nfl`

+`football_nfl`/`hockey_nhl` (those are PropLine's keys in `proplineAdapter`).
+`oddsService.SPORT_KEYS` + `SPORT_MARKETS` carry both; `proplineAdapter.MARKETS`
+filled. NHL keys (`player_shots_on_goal`, `goalie_saves`) added to
+`MARKET_MAP` so NHL props don't silently normalize to zero in-season.
+
+## Public Route Rate Limiting (Session 32)
+`middleware/rateLimit` (`createRateLimit`, in-memory per-IP, independent
