ROOT CAUSE: the Dockerfile copied src/poller/scripts/supabase but NOT
content/. mediaEngine.js read content/stark-lines.json with an unguarded
module-load readFileSync; ENOENT in the image threw at require time, and
via app.js → routes/desk → deskService → mediaEngine that crashed the
ENTIRE API at boot. The Coolify healthcheck rolled back to the last
healthy image (4d2b27d), so every deploy since 219167e silently served a
14-hour-old build — S11 live tracking, S6 API code, the settlement boot
line, and SNAPSHOT_EXPECTED_INTERVAL were all merged but NOT running.
FIX (one train):
1. Dockerfile COPYs content/ into the runner image.
2. mediaEngine: stark-lines.json is OPTIONAL (garnish, never load-bearing)
— loadStark() try/catch → {} → posts render without the Stark kicker,
never a crash. Belt AND suspenders with #1.
3. src/preflight.js (§A4): boot prints '[preflight] OK' or 'DEGRADED'
naming exactly what content/env is missing — before the healthcheck
can fail silently. Run first in server.js.
4. Full fragility sweep: mediaEngine was the ONLY unguarded module-load
file read; coachSignals (config/coaches.json) was already lazy +
try/catch + copied. No others.
Verified: requiring app.js + deskService + mediaEngine with
stark-lines.json ABSENT now boots clean (reproduced the exact prod
failure). 2757 -> 2763 tests (tests/unit/bootResilience.test.js).

The on-demand "Read" grade model is RETIRED. A scheduled pipeline pre-grades the
slate, locks grades to the line, tracks movement; the dashboard shows them already
there. Orchestrates existing services — nothing rebuilt.
- snapshotService.runSnapshot(sport): getOdds → gradeAndCacheSlate → classify
archetype per player → lock gradedAt → line deltas vs previous snapshot → write
snapshot:{sport}:latest/previous + grades:{sport} → ticker events. Fully
injectable, zero-network unit tests. runAllSnapshots = cron entrypoint.
- Internal trigger POST /api/internal/snapshot/:sport + /all (requireInternalAuth).
In-process cron (SNAPSHOT_CRON=1, UTC 14,19,22,1,3) in server.js, no new dep.
- Public reads: GET /api/snapshot/:sport (cache-only) + GET /api/ticker (merges
TICKER_MANUAL pins) + Next proxies.
- GameCard swap: live Slate renders vyndr/GameCard (legacy kept for types only),
overlays locked grades onto game props → player name once + archetype badge +
"Graded Xh ago at -115 · Current 2.5 · ▲ TOWARD +1.0". Ungraded → "Awaiting next
scan", NO Read button. On-demand onGrade flow deleted.
- Ticker polls /api/ticker every 30s, graceful fallback to hardcoded items.
- NBA/WNBA: espnStatsAdapter free fallback (defensive parse → found:false on shape
mismatch) wired into resolvePlayerStats after the offline Python service.
Env: PROPLINE_API_KEY_1/2/3, VYNDR_INTERNAL_KEY, SNAPSHOT_CRON=1, TICKER_MANUAL.
Backend 2061 -> 2100 tests (+39), 173 suites. Web build clean (exit 0).
