* feat(eia): move /api/eia/petroleum to gold-standard (Railway seed → Redis → Vercel reads only)
Live api.eia.gov fetches from the Vercel edge function were causing
FUNCTION_INVOCATION_TIMEOUT 504s on /api/eia/petroleum (Sydney edge →
US origin with no timeout, no cache, no stale fallback — one EIA blip
blew the 25s budget).
- New seeder scripts/seed-eia-petroleum.mjs — fetches WTI/Brent/
production/inventory from api.eia.gov with per-fetch 15s timeouts,
writes energy:eia-petroleum:v1 with the {_seed, data} envelope.
Accepts 1-of-4 series; 0-of-4 routes to contract-mode RETRY so
seed-meta stays stale and the bundle retries on next cron.
- Bundled into seed-bundle-energy-sources.mjs (daily, 90s timeout) —
no new Railway service needed.
- Rewrote api/eia/[[...path]].js as a Redis-only reader via
readJsonFromUpstash. Same response shape for backward compat with
widgets/MCP/external callers. 503 + Retry-After on miss (never 504).
- Registered eiaPetroleum in api/health.js STANDALONE_KEYS + gated as
ON_DEMAND_KEYS for the deploy window; promote to SEED_META
(maxStaleMin: 4320) in a follow-up after ~7 days of clean cron.
- Tests: 14 seeder unit tests + 9 edge handler tests.
Audit result: /api/eia/petroleum was the only Vercel route fetching
dashboard data live. Every other fetch(https://…) in api/ is
auth/payments/notifications/user-initiated enrichment.
* fix(eia): close silent-stale window — add SEED_META + seed-health registration
Review finding on PR #3161: without a SEED_META entry, readSeedMeta
returns seedStale: null and classifyKey never reaches STALE_SEED.
That meant a broken Railway cron or missing EIA_API_KEY after the first
successful seed would keep /api/eia/petroleum serving stale data for
up to 7 days (TTL) while /api/health reported OK.
- api/health.js: add SEED_META.eiaPetroleum with maxStaleMin=4320
(72h = 3× daily bundle cadence). Keep eiaPetroleum in ON_DEMAND_KEYS
so the Vercel-instant / Railway-delayed deploy window doesn't CRIT
on first seed, but stale-after-seed now properly fires STALE_SEED.
- api/seed-health.js: register energy:eia-petroleum in SEED_DOMAINS
(intervalMin=1440) so the secondary health endpoint reports it too.
- Updated ON_DEMAND_KEYS comment to reflect freshness is now enforced.
