* feat(correlation): server-side correlation engine seed + bootstrap hydration
Move correlation card computation from client-side (per-browser, 10-30s delay)
to server-side (Railway cron, instant via bootstrap). Seed script reads 8 Redis
keys, runs 4 adapter signal collectors (military, escalation, economic, disaster),
clusters/scores/generates cards, writes to Redis with 10min TTL.
- New: scripts/seed-correlation.mjs (pure JS port of correlation engine)
- bootstrap.js: add correlationCards to FAST_KEYS tier
- health.js + seed-health.js: register for monitoring (maxStaleMin: 15)
- CorrelationPanel: consume bootstrap on construction, show "Analyzing..." only
after live engine has run (not for bootstrap-only cards)
- _seed-utils.mjs: support opts.recordCount override (function or number)
* fix(correlation): stale timestamp fallback + coordinate-based country resolution
P1: news stories lacked per-story pubDate, causing Date.now() fallback on
every seed run. Now _clustering.mjs propagates pubDate through to
enrichedStories, and seed-correlation reads s.pubDate then generatedAt.
P2: normalizeToCode dropped signals with unparseable country names.
Added centroid-based coordinate fallback (haversine nearest-match within
800km) matching the live engine's getCountryAtCoordinates behavior.
* fix(correlation): add 11 missing country centroids to coordinate fallback
CI, CR, CV, CY, GA, IS, LA, SZ, TL, TT, XK were in the normalization
maps but missing from COUNTRY_CENTROIDS, causing coordinate-only signals
in those countries to be misclassified or dropped during bootstrap.
* fix(correlation): align protest/outage field names with actual Redis schema
Codex review P1 findings: seed-correlation read wrong field names from
Redis data.
Protests (unrest:events:v1): p.time -> p.occurredAt, p.lat/lon ->
p.location.latitude/longitude, severity enum SEVERITY_LEVEL_* mapping.
Outages (infra:outages:v1): o.pubDate -> o.detectedAt, o.lat/lon ->
o.location.latitude/longitude, severity enum OUTAGE_SEVERITY_* mapping.
Both escalation and disaster adapters updated. Old field names kept as
fallbacks for data shape compatibility.
