Review feedback on PR #3238: (1) Intl unhealthy → was silently overwriting aviation:delays:intl:v3 with an empty or partial snapshot because fetchAll() always returned { alerts } and zeroIsValid:true let runSeed publish. Now: • seedIntlDelays() returns { alerts, healthy, skipped } unchanged • fetchAll() refuses to publish when !healthy || skipped: - extendExistingTtl([INTL_KEY, INTL_META_KEY], INTL_TTL) - throws so runSeed enters its graceful catch path (which also extends these TTLs — idempotent) • Per-run cache (cachedRun) short-circuits subsequent withRetry(3) invocations so the retries don't burn 3x NOTAM quota + 3x FAA/RSS fetches when intl is sick. (2) NOTAM quota exhausted — PR claimed "preserved" but only logged; the NOTAM data key was drifting toward TTL expiry and seed-meta was going stale, which would flip api/health.js maxStaleMin=240 red after 4h despite the intended 24h backoff window. Now matches the pre-strip ais-relay behavior byte-for-byte: • extendExistingTtl([NOTAM_KEY], NOTAM_TTL) • upstashSet(NOTAM_META_KEY, {fetchedAt: now, recordCount: 0, quotaExhausted: true}, 604800) Consumers keep serving the last known closure list; health stays green. Also added extendExistingTtl fallbacks on FAA/NOTAM network-rejection paths so transient network failures also don't drift to TTL expiry.

/**
|
||
* Consolidated aviation seeder. Writes four Redis keys from one cron tick:
|
||
*
|
||
* aviation:delays:intl:v3 — AviationStack per-airport delay aggregates (51 intl)
|
||
* aviation:delays:faa:v1 — FAA ASWS XML delays (30 US)
|
||
* aviation:notam:closures:v2 — ICAO NOTAM closures (60 global)
|
||
* aviation:news::24:v1 — RSS news prewarmer (list-aviation-news.ts cache)
|
||
*
|
||
* Also publishes notifications for new severe/major airport disruptions and new
|
||
* NOTAM closures via the standard wm:events:queue LPUSH + wm:notif:scan-dedup SETNX.
|
||
* Prev-alerted state is persisted to Redis so short-lived cron invocations don't
|
||
* re-notify on every tick.
|
||
*
|
||
* Supersedes: scripts/seed-airport-delays.mjs (deleted) + the in-process seed
|
||
* loops that used to live inside scripts/ais-relay.cjs (stripped). ais-relay still
|
||
* hosts the /aviationstack live proxy for user-triggered flight lookups.
