Covers routes/activities that enter the journal without BRouter waytags
(imports, uploads, pre-existing rows):
- overpass-ways.server.ts: server-side Overpass client (way[highway] + geom in
a bbox, configurable OVERPASS_URLS, timeout + oversized-bbox guard).
- surface-match.server.ts: pure nearest-way map-matcher → per-segment
surface/highway (unmatched → unknown). Unit-tested.
- surface-backfill pg-boss job: load geom → skip if breakdown exists → Overpass
→ match → computeSurfaceBreakdown → store → emit `surface_breakdown` SSE to
the owner. Idempotent, retry-safe, best-effort; registered in server.ts.
- Enqueued from createActivity (imports/uploads) + owner-on-open in the route &
activity detail loaders (non-Planner routes, old rows), deduped via singletonKey.
- useSurfaceBackfillUpdates: detail pages subscribe to /api/events and
revalidate() when their row's backfill lands (live bars, no reload).
- Privacy manifest updated (DE + EN) for the Overpass bbox lookup.
Tests: matchSurfaces unit; surface-backfill job (mocked Overpass/db/events:
store + emit, skip-if-present, skip-if-no-ways). Verified the real
Overpass→match→breakdown pipeline against a live Berlin bbox (509 ways →
plausible asphalt/paving_stones/footway mix). typecheck + lint + unit
(journal 333) green.
Note: the worker runs via server.ts (prod/staging), not `react-router dev`, so
the live job + SSE exercise on a deployed instance.
