Summary

После C-5 fix (PR #487) Avito coords либо NULL либо реальные. Estimator исключал source='avito' из radius search потому что раньше там был jitter (±0.005°) от 5 anchor cron'ов. Сейчас:

Source	Total active	NULL coords	В radius search?
avito	4 250	3 580 (84%)	❌ excluded
cian	2 698	38 (1%)	✅
yandex	1 293	641 (50%)	✅
n1	264	106 (40%)	✅

→ estimator ловит только cian/yandex/n1 = ~30% эффективной базы.

Bundled fix

app/tasks/geocode_missing.py — async callable с GeocodeBackfillResult dataclass. Batch geocoder (Nominatim 1/s или Yandex если key), dedup по address (5 listings одного дома → 1 geocode call → 5 UPDATE).
2 admin endpoints:
- GET /api/v1/admin/scrape/geocode-missing-listings/status — pending counters per source + estimated time
- POST /api/v1/admin/scrape/geocode-missing-listings?batch_size=200&dry_run=false&background=false — manual trigger
estimator.py:813 — убран AND source <> 'avito' (replaced with updated comment про PR #487).

Test plan

11/11 pytest tests pass (tests/tasks/test_geocode_missing.py)
ruff + mypy clean
Post-merge smoke:
- GET /admin/scrape/geocode-missing-listings/status → returns pending counters
- POST .../geocode-missing-listings?batch_size=10&dry_run=true → dry run выводит 10 addresses
- POST .../geocode-missing-listings?batch_size=200 × 8-12 раз → unique_addresses_pending → 0

Expected impact

4 365 listings нуждаются в geocode → ~1 500-2 500 unique addresses
Nominatim 1 req/sec → ~25-45 min total (с 1350 cached entries — быстрее)
После backfill: +4 166 Avito listings в radius search = +40% data
Confidence "high" будет в ~70% случаев вместо ~30%

Notes

Existing /admin/geocode-missing (per-listing) сохранён — coexist с новым (address dedup)
?background=true для большого batch (избегает HTTP timeout)
Frontend UI button — follow-up PR (worker сосредоточен на backend per task spec)

fix(tradein): geocode backfill + remove Avito exclusion from estimator fdfb74ca88

После C-5 fix (PR #487) Avito coords либо NULL либо реальные. Estimator
исключал source='avito' из radius search потому что раньше там был jitter
(±0.005°) от 5 anchor cron'ов. Сейчас:
- 3580 Avito + 641 Yandex + 106 N1 + 38 Cian listings без coords
- estimator._fetch_analogs ловил только cian/yandex/n1 = ~30% эффективной базы

Bundled fix:
1. app/tasks/geocode_missing.py — batch geocoder (Nominatim 1/s, dedup по address)
2. POST /admin/scrape/geocode-missing-listings + GET status — manual trigger
3. estimator.py: убран AND source <> 'avito' — после backfill Avito включён в radius

Result: после backfill +4166 Avito listings в radius search = +40% эффективной
data. Confidence "high" будет в ~70% случаев вместо ~30%.

Tests: 11 новых tests/tasks/test_geocode_missing.py — all pass.

Merged via deep-code-reviewer — verdict APPROVE.

Geocode dedup: correct. SELECT address, COUNT(*) ... GROUP BY address ORDER BY listings_count DESC LIMIT :limit → 1 geocode → N UPDATEs WHERE address = :addr AND lat IS NULL. Test test_geocode_missing_dedup_addresses_single_geocode_call подтверждает.

Nominatim rate limit: 1 req/sec соблюдён в geocoder.py:530 (await asyncio.sleep(1.0) после success) + line 187 (между typo variants). TOS compliant.

Estimator change justified: AND source <> 'avito' убран; existing safety net — ST_DWithin(geom, ...) отфильтровывает rows с NULL geom (а NULL coords → NULL geom через PostGIS trigger), так что pre-#487 jittered Avito (670 rows) не вызывают новых проблем самим фактом merge — но они появятся в radius search.

Merge order: можно мержить независимо от #487 — код forward-compat. Если #487 ещё open, рекомендуется merge first для исторической точности комментария.

Post-merge follow-ups (user action):

Smoke: GET .../status → POST batch_size=10&dry_run=true → POST batch_size=200&background=true ×8-12
ANALYZE listings; после первого full backfill (planner stats refresh)
Cleanup pre-#487 jittered Avito coords (670 rows): UPDATE listings SET lat=NULL, lon=NULL WHERE source='avito' AND scraped_at < '2026-05-23' AND lat IS NOT NULL; → re-backfill
Vault: code/modules/tradein/Geocode_Backfill.md (main session per worker-only-executes rule)
Verify confidence "high" rate в estimator: 30% → 70%

Minor non-blocking findings:

admin.py:389 duplicate from app.core.db import SessionLocal import (already line 19)
background=true + dry_run=true — silent BG dry-run (consider 400 error)
UPDATE WHERE address = :addr без source-filter — implicit cross-source coupling (acceptable, same address = same coords)
N COMMITs (1 per address) в batch — acceptable для one-time, если cronify — batch commit worth considering
