Critical demo-blocker: POST /analyze returns 202 {status:fetching} for parcels
whose geometry isn't cached yet (#93 on-demand НСПД fetch). useParcelAnalyzeQuery
treated 202 as success → the stub (no score/competitors) reached render → Section 3/4
threw TypeError → white screen (no error boundary). Repro confirmed on prod.
- useParcelAnalyzeQuery: 202-aware — poll /fetch-status (2s, 2-min cap), re-POST
on ready (status-checked, no stub on 202 race), throw HTTPError on
not_in_nspd/failed/invalid_format; horizon preserved in both POSTs; retry: false
- error boundaries: app/site-finder/analysis/[cad]/error.tsx + app/error.tsx —
no white screen ever; calm RU message in prod, error detail in dev
- Section3/Section4: guard competitors/score against partial payloads
- CadInput: drop hardcoded default cad (empty + placeholder), raw hex → tokens
Map parcel-select already fixed by 3cea915. Part of EPIC #958.
