B7: stop AdminDashboard refetching the case list on selection change
selectedCaseId was both read and written inside the list-loading effect and
listed in its deps, causing a second fetch on first render and after every
filter reset. Auto-select now uses a functional state update, so the effect
no longer depends on selectedCaseId; editForm stays in sync via the existing
selectedCase effect.
_extract_json_payload handles a json/JSON/bare fence, raw JSON and JSON
embedded in prose; any unparseable response or contract violation now
degrades to the deterministic scoring_service instead of raising.
Also guards the response envelope itself (content[0].text).
B3: single home for recommendation scoring
services/recommendation_service.py holds the rules; routers/stats.py and
backend/services/stats_service.py both delegate to it. Unified rules are the
union of the two old copies: same weights/threshold, substring matching
(superset of the old exact match), tolerant key aliases, health_flags rule
kept. Endpoint response contract unchanged.
Plus: Overpass circuit breaker and concurrent zone queries in geo_service -
128 sequential calls per analysis no longer each burn a connect timeout when
the host has no outbound network.
Tests: 152 -> 194 passed.
backend/routers/analyze.py imports services.* (root package), not
backend.services.* - so the earlier A1/A2/A3 edits landed in an unused
duplicate. Also COPY/mount services/ so the container can start at all
(ModuleNotFoundError: No module named services).
