Adds «6.4 Рекомендация по продукту» to Section6Forecast — the §13.4
product recommendation (class, unit-mix, commercial, USP, §16 reasons)
that previously existed only in the export renderers. Unit-mix is shown
as token-colored horizontal bars; since the assembler emits no per-format
share (pct), bars are honestly labeled as a deficit-by-format signal, not
a build-share. Graceful on thin/202-pending/partial reports.
- types/forecast.ts: ReportProductTz + nested interfaces, optional on ForecastReport
- ForecastProductTzBlock.tsx: per-field guards, role=img bars, reasons disclosure
- forecast-helpers.ts: deficitBarWidthPct
- Section6Forecast + sidebar nav: wire 6.4
Part of #958.
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.
Segmented control «Горизонт прогноза» driving the analyze query (?horizon=)
and Section 6's target highlight. Default 12.
- HorizonSelector: radiogroup + a11y radios, tokens-only, tabular-nums,
disabled while a re-analyze is in flight
- useParcelAnalyzeQuery(cad, horizon=12): horizon in queryKey + ?horizon=;
keepPreviousData so switching horizon doesn't blank the page to loading
- AnalysisPageContent: horizon state + forecast-poll invalidation on change
- Section6Forecast/ForecastHorizonsBlock: selectedHorizon → target row («Целевой»)
Part of EPIC #958.
Marker click opens an interactive Leaflet popup with a primary "Открыть анализ"
action that navigates to /site-finder/analysis/<cad> (encodeURIComponent —
matches the [cad] route's single-decode contract) and records the visit in
RecentParcels. Hover tooltip enriched with status + actionable hint. Existing
ParcelDrawer preview kept, reachable via the popup's secondary "Подробнее".
ESLint + tsc clean.
Wire analysis/[cad]/page.tsx: replace SidebarPlaceholder with
AnalysisSidebar (sticky, IntersectionObserver scrollspy on sections
1/2/3/3.1/3.2/3.3/4/5), header with AnalysisBreadcrumb (SiteFinder
→ cad → Анализ) and UserAvatar (gd_org_id from localStorage, SSR-safe).
Add lucide-react to package.json (was used in A1 but missing from deps).
* feat(site-finder): auto-fetch cadastre geometry on-demand (#93)
Когда пользователь вводит cad-номер которого нет в БД (cad_quarters_geom /
cad_buildings / cad_parcels_geom), вместо 404 «Загрузи через NSPD geo» (dead-
end для non-admin) — теперь backend автоматически инициирует NSPD fetch,
frontend показывает loading state с polling /fetch-status каждые 2с.
Backend:
- Новый модуль app/services/site_finder/cadastre_fetch.py с helpers:
find_or_enqueue_fetch (atomic check + enqueue с дедупликацией по cad),
fetch_status (smart polling endpoint — отличает not_in_nspd от failed),
detect_thematic_id (3-сегм quarter / 4-сегм parcel / 5-сегм building),
validate_cad_format.
- Reuse: enqueue_geo_job + process_nspd_geo_job (workers/tasks/nspd_geo).
source_kind='auto_on_demand' отличает от bulk; rate_ms=200, priority=9.
- POST /parcels/{cad}/analyze graceful fallback: inline await до 25s
(fast path), затем 202 + job_id + eta_seconds для polling, либо
400/404/503 в зависимости от статуса (с Retry-After 60s на 503).
- GET /parcels/{cad}/fetch-status новый endpoint для polling.
Frontend:
- useSiteAnalysis расширен: fetchingState + cancel(). POST analyze + при 202
polling каждые 2с (max 60 итераций = 2 мин cap). status=ready → re-trigger
analyze; not_in_nspd/failed/invalid_format → typed errors.
- apiFetchWithStatus<T> + HTTPError в lib/api.ts — status-aware variant
для 200 vs 202.
- FetchingState.tsx: animated spinner, progress bar (linear до etaSeconds,
asymptote после), elapsed counter, cancel button. Светло-голубая
scheme отличается от обычного pending skeleton.
- site-finder/page.tsx: FetchingState когда fetchingState активен; обычный
pending skeleton — только при первичном analyze без 202.
Edge cases (per #93 acceptance):
- cad валидный в НСПД, fetch <25s → inline 200 OK
- cad валидный, fetch >25s → 202 + frontend polls → ready → analyze
- cad валидный, не в НСПД → 404 с понятным сообщением + формат hint
- cad invalid format → 400 + формат hint
- NSPD rate-limited / failed → 503 + Retry-After 60s
- Параллельные запросы на тот же cad → один job, оба клиента poll'ят (дедуп
через find_active_on_demand_job).
Closes#93.
* fix(site-finder): address PR #95 auto-review minor feedback
Backend (cadastre_fetch.py):
1. (race condition) Advisory lock `pg_try_advisory_xact_lock(hashtext(cad_num))`
обёрнут вокруг шагов "check active job → enqueue" в find_or_enqueue_fetch.
Lock transaction-scoped, released at COMMIT. Параллельные запросы на тот
же cad: первый получает lock и enqueue; второй lock=false → re-check
active job (уже виден после первого COMMIT) → возвращает тот же job_id.
Docstring обновлён, упоминание SELECT FOR UPDATE удалено.
Backend (parcels.py):
3. (threadpool exhaustion) _INLINE_FETCH_WAIT_S снижен 25 → 15s с подробным
комментарием: tradeoff про default Starlette anyio threadpool (40 slots)
и concurrent burst saturation. 15s баланс: НСПД avg 5-15s для quarter,
~70% fast path; остальные 30% получают 202 + polling без блока.
Data (87_on_demand_indexes.sql):
2. (missing index) New migration:
- `nspd_geo_targets_cad_num_idx ON nspd_geo_targets(cad_num)` — для
find_active/recent_completed_job (existing UNIQUE composite не покрывает
WHERE cad_num=:c).
- `nspd_geo_jobs_source_status_idx ON nspd_geo_jobs(source_kind, status)`
composite для filter auto_on_demand + queued/running.
Idempotent (CREATE INDEX IF NOT EXISTS), не блокер при текущем размере,
критично при росте on-demand traffic.
Frontend (useSiteAnalysis.ts):
4. (UI flicker) setFetchingState(null) перемещён ПОСЛЕ `await second
apiFetch`. Иначе между clear и resolve есть момент когда mutation
isPending=true + fetchingState=null → пустой экран ~1 RTT.
NOT addressed (rebuttal):
5. (Tailwind convention) — проверил: в проекте нет ни globals.css, ни
@tailwind directives. ВСЕ существующие site-finder components используют
inline styles (ConfidenceBadge, GeotechRiskBlock, ScoreBreakdownPanel etc).
Tailwind в deps но не wired up. Keep inline styles для consistency.
6. (animate-spin) — требует Tailwind globals (см. #5). `<style jsx>`
keyframes — built-in Next.js, работает.

* feat(site-finder): deep-link tabs via ?tab=env|land|market URL param
Tab state now syncs with URL — можно поделиться ссылкой на конкретный
таб (например /site-finder?tab=market для тренда цен по последнему cad).
- useRouter + useSearchParams (Next 15 app router, client-component)
- router.replace (не push) чтобы tab switches не засоряли history
- useEffect on searchParams → back/forward работают
- overview = default, не пишется в URL (clean)
- Type-guard isTabId(): только valid values из URL переключают state
* fix(site-finder): address PR #86 auto-review minor recommendations
- Use usePathname() for router.replace fallback (avoid dangling "?" in Next 15)
- Remove stale-closure guard in useEffect — React bails Object.is, no eslint-disable
- Wrap page in <Suspense> for useSearchParams (Next 15 App Router req for static)
- Lazy useState initializer — skip wasted CPU on re-renders
