Summary

Заменяет tradein.cad_buildings snapshot (36k rows, frozen 2026-05-22 manual import) на live postgres_fdw foreign table читающую напрямую gendesign.v_tradein_cad_buildings. Откатывает HTTP-подход PR #492 (cadastral.py endpoint) — заменён на FDW.

Fixes:

/trade-in/api/v1/geocode/reverse 500 (Nominatim ban → RetryError всплывал — теперь try/except wrap + cadastral primary)
estimate.confidence_explanation=address_not_geocoded для адресов в нашей кадастре (e.g. estimate 9a08503e Хохрякова 81 — есть в cad_buildings, но Nominatim возвращает [])

Architecture

main gendesign:

new SQL migration data/sql/100_tradein_fdw_role.sql — role tradein_fdw_reader (passwordless CREATE ROLE ... LOGIN; password set отдельно через deploy.yml ALTER ROLE bootstrap) + flat VIEW v_tradein_cad_buildings (EKB only). REVOKE perimeter на public schema.
docker-compose.prod.yml — main postgres в gendesign_shared network с alias gendesign-postgres
.forgejo/workflows/deploy.yml — post-migration bootstrap: ALTER ROLE tradein_fdw_reader WITH PASSWORD :env (читает GENDESIGN_FDW_PASSWORD из /opt/gendesign/backend/.env.runtime)
удалён backend/app/api/v1/cadastral.py (PR #492 HTTP endpoint — больше не нужен)

tradein-mvp:

tradein-mvp/backend/data/sql/060_postgres_fdw_extension.sql — CREATE EXTENSION postgres_fdw, CREATE SERVER gendesign_remote (host=gendesign-postgres, connect_timeout=3), CREATE FOREIGN TABLE gendesign_cad_buildings
tradein-mvp/backend/data/sql/061_drop_legacy_cad_buildings.sql — DROP TABLE cad_buildings
удалены: 006_cad_buildings.sql, deploy/import-cadastre.sh
tradein-mvp/backend/app/core/fdw.py — ensure_fdw_user_mapping(db): regex whitelist на password ([A-Za-z0-9_-]{32,256}, fail-fast на mismatch без эха значения), idempotent CREATE/ALTER USER MAPPING; вызывается из FastAPI lifespan startup
geocoder.py — _cadastral_forward_sync + _cadastral_reverse_sync через FDW, обёрнуты в asyncio.to_thread (non-blocking); geocode()/reverse_geocode()/suggest() flow: cadastral → Yandex → Nominatim; reverse_geocode wrapped try/except → возвращает None вместо raising → 404 вместо 500
house_metadata.py и trade_in.py admin stats — switched to foreign table
tradein-mvp/docker-compose.prod.yml — postgres в gendesign_shared, backend env GENDESIGN_FDW_PASSWORD

Verification (мной перед PR)

SQL прогон на проде против gendesign.cad_buildings:

✅ Reverse 56.8518, 60.5671 (user 500-ка) → ул. Готвальда 15 в 71m
✅ Reverse 56.8606, 60.6155 → Трамвайный 2/2 dist=0.0 (cad_num 66:41:0205019:1105)
✅ Forward Хохрякова 81 → найдено (cad_num 66:41:0401034:66, lat=56.8274, lon=60.5953) — был address_not_geocoded в проде
✅ pg_trgm fuzzy Цвилинга → Цвиллинга sim=0.39

Test plan

post-deploy: docker exec tradein-postgres psql -U tradein -d tradein -c 'SELECT count(*) FROM gendesign_cad_buildings' → ~36k
post-deploy: curl ...trade-in/api/v1/geocode/reverse?lat=56.8518&lon=60.5671 → 200 + ул. Готвальда
post-deploy: re-submit estimate с адресом Хохрякова 81 → n_analogs > 0, confidence != address_not_geocoded
map-picker UI в ЖК Малевич → жилой дом подставился
GlitchTip без новых RetryError/HTTPStatusError от geocode

Deploy ordering

PR merge → main deploy.yml apply 100_*.sql (создаёт role + view, REVOKE/GRANT)
Bootstrap step: deploy.yml читает GENDESIGN_FDW_PASSWORD из VPS backend/.env.runtime → ALTER ROLE tradein_fdw_reader WITH PASSWORD ... (idempotent)
Main postgres recreated с gendesign_shared network
tradein deploy (deploy-tradein.yml) → apply 060_*.sql + 061_*.sql
tradein backend startup → ensure_fdw_user_mapping создаёт USER MAPPING с тем же паролем из tradein env
Verify: SELECT count(*) FROM gendesign_cad_buildings в tradein-postgres → ~36k

Pre-deploy manual step

Добавить в оба .env.runtime на VPS (main + tradein):

/opt/gendesign/backend/.env.runtime — для deploy.yml ALTER ROLE bootstrap
/opt/gendesign/tradein-mvp/.env.runtime — для tradein backend USER MAPPING

Значение GENDESIGN_FDW_PASSWORD — в vault meta/00_credentials.md раздел "FDW reader role". Старый password (commit 698ef4f) abandoned — role с ним никогда не создавалась на проде.

Security

Deep review fixes (commit fixup на этой ветке):

🔴 C1 password literal в SQL миграции — убран; bootstrap из env
🔴 C2 SQL injection в fdw.py — regex whitelist + format validation
🟠 H3 FDW connect_timeout=3
🟠 H4 sync DB в async → asyncio.to_thread
🟠 H5 REVOKE perimeter

Tests

Rewritten test suite + 3 new SQL-injection guard cases для ensure_fdw_user_mapping.

feat(tradein): postgres_fdw live read of gendesign.cad_buildings (replaces snapshot) 698ef4f003

Replaces tradein.cad_buildings manual snapshot (36k rows, frozen 2026-05-22) with
live postgres_fdw foreign table reading gendesign.v_tradein_cad_buildings directly.
Also reverts PR #492 HTTP-based cadastral.py — superseded by FDW.

Architecture:
- gendesign DB: new role tradein_fdw_reader + flat view v_tradein_cad_buildings
  (EKB-only slice of cad_buildings with lat/lon flattened from geom)
- networks: gendesign-postgres added to gendesign_shared (alias);
  tradein-postgres added to gendesign_shared for FDW connect
- tradein DB: postgres_fdw extension + FOREIGN TABLE gendesign_cad_buildings
- tradein backend: startup hook creates/refreshes USER MAPPING with password
  from env GENDESIGN_FDW_PASSWORD (password rotation handled via restart)
- geocoder.py: cadastral primary for forward + reverse + suggest;
  Yandex/Nominatim fallback. reverse_geocode wraps Nominatim in try/except —
  no more HTTPStatusError → 500.
- house_metadata.py and trade_in.py admin stats switched to foreign table
- DROP TABLE cad_buildings in tradein (legacy snapshot removed entirely)
- import-cadastre.sh deleted (no manual sync needed)

Fixes:
- /trade-in/api/v1/geocode/reverse 500 (Nominatim ban → no fallback)
- estimate confidence_explanation=address_not_geocoded for addresses in our
  cadastre (e.g. Хохрякова 81) that Nominatim doesn't return

Deploy ordering: main migration 100_tradein_fdw_role.sql adds role+view first
(strict deploy.yml). Tradein next deploy applies 060_postgres_fdw_extension.sql
and 061_drop_legacy_cad_buildings.sql (idempotent, errors ignored). Tradein
backend startup creates USER MAPPING when env var present. Verify post-deploy
with: docker exec tradein-postgres psql -U tradein -d tradein -c \
  "SELECT count(*) FROM gendesign_cad_buildings"  # expect ~36k EKB buildings.

🔴 BLOCK — критические security issues, НЕ мержить

Deep review результат: 2 critical + 3 high + 5 medium + 5 low.

🚨 Critical #1: Real production password committed в SQL миграцию

data/sql/100_tradein_fdw_role.sql:142:

CREATE ROLE tradein_fdw_reader LOGIN PASSWORD '40473b7c10c7474855c7d1aa98f0fd0a0de2499aef0cbd1fead06c9641e4dcd8';

Тот же password дублирован в:

PR body (Forgejo description — публично читабелен для всех с read доступом к репо)
vault meta/00_credentials.md

Violation: CLAUDE.md rule #1 «❌ Hardcode credentials в коде / коммитах».

Blast radius: anyone с read access к репо (GHCR mirrors, backups, GHA artifacts, CI logs) теперь имеет FDW read access на главную БД gendesign через role tradein_fdw_reader.

Fix:

Убрать PASSWORD '...' из 100_*.sql — оставить только CREATE ROLE tradein_fdw_reader LOGIN

Set password через bootstrap shell script с env var:

psql -c "ALTER ROLE tradein_fdw_reader WITH PASSWORD '$GENDESIGN_FDW_PASSWORD_ADMIN'"

Edit PR body — убрать password
Consider git filter-repo history rewrite (только если password high-risk; private repo + admin-only = acceptable risk если rotate done)

🚨 Critical #2: SQL injection vector в `core/fdw.py`

ensure_fdw_user_mapping использует f-string interpolation с only ' escape:

escaped_pw = password.replace("'", "''")
db.execute(text(
    f"CREATE USER MAPPING FOR CURRENT_USER SERVER gendesign_remote "
    f"OPTIONS (user 'tradein_fdw_reader', password '{escaped_pw}')"
))

Потенциальные обходы (зависят от encoding / unicode):

RIGHT SINGLE QUOTATION MARK (U+2019) → может surprise
Null byte / backslash variations

Fix:

Validate password format на input: re.fullmatch(r"[A-Za-z0-9_\-]{32,}", password) — fail-fast с понятным error
Comment в коде явно: «password format restricted to hex/alphanumeric to prevent quote-injection»
Strict path: psycopg.sql.SQL(...).format(psycopg.sql.Literal(password)) через прямой psycopg connection (SQLAlchemy text() не поддерживает)

🟠 High #3: FDW SERVER без `connect_timeout`

060_postgres_fdw_extension.sql:

CREATE SERVER gendesign_remote FOREIGN DATA WRAPPER postgres_fdw
  OPTIONS (host 'gendesign-postgres', dbname 'gendesign', port '5432', extensions 'postgis');

Если gendesign-postgres недоступен (downtime во время compose up -d --force-recreate) — FDW queries будут висеть до default TCP timeout (≥75 сек по Linux), блокируя event-loop тред.

Fix: добавить OPTIONS (..., connect_timeout '3').

🟠 High #4: Sync DB call внутри `async def` blocks event loop

geocoder._cadastral_forward_sync / _cadastral_reverse_sync — db.execute(text(...)) вызывается из async def suggest() / async def reverse_geocode().

Regression vs PR #492 который использовал httpx.AsyncClient (non-blocking).

При FDW outage handler заблокирует worker thread на ≥75 сек.

Fix: либо

asyncio.to_thread(_cadastral_forward_sync, ...), либо
db.execute(text("SET LOCAL statement_timeout = '3000'")) перед FDW query

🟠 High #5: Role privileges — нет explicit REVOKE perimeter

100_*.sql grants USAGE ON SCHEMA public TO tradein_fdw_reader. Если любая existing table в gendesign.public имеет GRANT SELECT TO PUBLIC — tradein_fdw_reader её видит.

Fix (defense-in-depth):

REVOKE ALL ON ALL TABLES IN SCHEMA public FROM tradein_fdw_reader;
REVOKE ALL ON ALL SEQUENCES IN SCHEMA public FROM tradein_fdw_reader;
GRANT SELECT ON v_tradein_cad_buildings TO tradein_fdw_reader;

🟡 Medium (non-blocking)

fdw.py:319 pg_user_mappings.usename = current_user промахнётся для CREATE USER MAPPING FOR PUBLIC (usename=NULL) → fix: (usename = current_user OR usename IS NULL)
fdw.py:336 db.commit() без try/except — recommend explicit db.rollback() в except
061_*.sql DROP TABLE ... CASCADE — recommend перечислить ожидаемые зависимости в комментарии
Deploy ordering race — tradein backend стартует до main postgres ready → mapping создан, queries fail → graceful degradation OK, но recommend post-deploy docker restart tradein-backend
Tradein deploy ahead of main — foreign table указывает на view которого ещё нет → recommend precheck SELECT 1 FROM gendesign_cad_buildings LIMIT 1 в startup

🟢 Low nits

100_*.sql:155 redundant ::numeric cast на round() output
geocoder.py:546 provider="nominatim" для cadastral hits — recommend отдельный enum value "cadastre"
house_metadata.py:701-708 magic numbers ±0.0010° — extract constants
geocoder.py:466 regex '(гараж|снт|садовод|товарищ|уч\.)' — уч\. ловит false positives
060_*.sql DROP FOREIGN TABLE IF EXISTS снаружи DO-блока — recommend savepoint wrap

🚨 URGENT user actions (немедленно)

🔄 ROTATE password на VPS:

ssh gendesign 'docker exec gendesign-postgres psql -U postgres -c "ALTER ROLE tradein_fdw_reader WITH PASSWORD '\''<NEW_RANDOM>'\''"'

✏️ Update VPS .env.runtime GENDESIGN_FDW_PASSWORD на новый
✏️ Update vault meta/00_credentials.md — новый password
✏️ Edit PR body в Forgejo — убрать password literal
🛠 Worker fixup — fix #1-#5 в priority order, новый push, re-review

Tests gap

Missing tests:

ensure_fdw_user_mapping idempotency (CREATE → ALTER path, password update)
SQL injection unit test: password = "x' OPTIONS (whatever_evil" → должен reject

  bootstrap step reading GENDESIGN_FDW_PASSWORD from backend/.env.runtime.
- tradein-mvp/backend/app/core/fdw.py — strict regex whitelist on password
  ([A-Za-z0-9_-]{32,256}) before inlining into DDL; ValueError on mismatch
  (no password in error message); pg_user_mappings query corrected for
  PUBLIC mapping (usename IS NULL); commit wrapped in try/rollback.

High:
- 060_postgres_fdw_extension.sql — connect_timeout='3' added to FOREIGN
  SERVER; ALTER SERVER ADD/SET fallback for re-apply path.
- geocoder.py — _cadastral_forward_sync / _cadastral_reverse_sync wrapped in
  asyncio.to_thread to avoid blocking event loop on FDW outage.

Tests:
- 3 new test_cadastral_reverse.py cases: SQL injection password rejected,
  short password rejected, valid hex password accepted with mapping creation.

Old password 40473b7c... remains in git history at 698ef4f (force-push
forbidden) — but the role was never created with it on prod (SQL not
deployed), so abandoned. New password 72df... lives only in VPS env files
and vault meta/00_credentials.md.

Merged via deep-code-reviewer — verdict APPROVE.

Re-review after fixup 6507a5af confirmed all 5 BLOCK findings resolved:

C1 (password literal) — RESOLVED. 100_tradein_fdw_role.sql creates passwordless CREATE ROLE ... LOGIN. Password injected by .forgejo/workflows/deploy.yml bootstrap step via psql -v pw=$GENDESIGN_FDW_PASSWORD + format('... %L', :'pw') — :'pw' is psql client-side variable interpolation (safe quoting), %L is server-side literal escape. Double-layer injection-safe.
C2 (SQL injection in fdw.py) — RESOLVED. Regex ^[A-Za-z0-9_\-]{32,256}$ whitelist before f-string inlining; ValueError on mismatch without echoing the password value. Inlining DDL is unavoidable (postgres OPTIONS doesn't accept bind params), but whitelist makes value provably injection-safe.
H3 (FDW connect_timeout) — RESOLVED. connect_timeout '3' in CREATE SERVER OPTIONS + ALTER SERVER ADD/SET fallback for re-apply path.
H4 (sync DB in async) — RESOLVED. _cadastral_forward_sync and _cadastral_reverse_sync wrapped in asyncio.to_thread(...) at all 3 call sites (suggest, geocode, reverse_geocode).
H5 (REVOKE perimeter) — RESOLVED. Explicit REVOKE ALL ON ALL TABLES/SEQUENCES/FUNCTIONS IN SCHEMA public + only GRANT SELECT ON v_tradein_cad_buildings.

Bonus: pg_user_mappings query now correctly handles PUBLIC mapping (usename IS NULL); db.commit() wrapped in try/rollback; 3 SQL-injection guard tests added.

No new file beyond what was listed previously — the +105 lines went into existing files (deploy.yml bootstrap +21, fdw.py rewrites, geocoder/test rewrites). changed_files jumped 17→18 because PR description recounted after cadastral.py deletion was made explicit.

Deploy verification checklist remains as in PR body (post-merge ALTER ROLE + tradein restart + count gendesign_cad_buildings).
