* fix(tech-events): prevent partial fetch results from being cached
Techmeme ICS and dev.events RSS fetches on Vercel edge can partially
fail (timeout, truncation), returning only 1 event instead of 20+.
The handler cached this partial result for 6 hours, causing the Tech
Events panel to show empty.
- Add 8s AbortSignal.timeout on both external fetches
- Require minimum 5 events before caching (at least curated count)
* fix(tech-events): remove MIN_EVENTS threshold and add diagnostic logging
The MIN_EVENTS=5 threshold caused empty results when both external
sources fail on Vercel edge (only 4 curated events available). Now
any events > 0 are cached. Added detailed logging to diagnose why
Techmeme ICS and dev.events RSS fetches fail on Vercel edge.
Also removed past STEP Dubai 2026 event.
* fix(tech-events): route fetches through Railway relay when direct fails
Vercel edge functions cannot reliably reach Techmeme ICS and dev.events
RSS (datacenter IP blocking). Added fetchTextWithRelay() that tries
direct fetch first, then falls back to Railway relay proxy (/rss endpoint)
which fetches from a different IP. Same pattern used by news feed digest
and other handlers that hit blocked external sources.
* feat(tech-events): gold standard pipeline with Railway seed + bootstrap hydration
Full data pipeline overhaul to match project conventions:
- Add tech events seed loop to ais-relay.cjs: fetches Techmeme ICS +
dev.events RSS every 6h from Railway (avoids Vercel IP blocking),
parses both sources, merges with curated fallback events, writes to
Redis (data key + bootstrap key + seed-meta)
- Register in api/bootstrap.js BOOTSTRAP_CACHE_KEYS (SLOW tier)
- Register in api/health.js BOOTSTRAP_KEYS + SEED_META (420min stale)
- Restructure RPC handler: reads from single broad Redis key (populated
by seed), applies geocoding + filtering in-memory per request params.
Fallback fetcher only runs on cold start before first seed
- TechEventsPanel: check getHydratedData('techEvents') from bootstrap
before falling back to RPC call
- data-loader: use hydrated bootstrap data for map layer, RPC fallback
