feat(db): schema user_weight_profiles (#114 sub-PR 1/4 — foundation) (#136)
Per #114 Custom POI weights — Макс feedback "садики и Мегамарт должны
иметь разные веса". Sub-PR 1/4 per feedback_split_big_issues:
1. **#114 sub-PR 1 (this)**: schema migration
2. #114 sub-PR 2: backend Pydantic models + CRUD service
3. #114 sub-PR 3: POST /parcels/{cad}/analyze?profile= override + admin endpoint
4. #114 sub-PR 4: frontend 25 sliders UI + live preview
## Schema
`data/sql/90_user_weight_profiles.sql`:
- Table `user_weight_profiles` — SERIAL PK + user_id + profile_name +
weights JSONB + is_default + timestamps
- Unique constraint (user_id, profile_name)
- B-tree index user_idx
- Partial index `WHERE is_default = TRUE` (fast default lookup)
- Trigger auto-updated_at via `set_updated_at()` function
## Compat with existing POI categories
`weights` JSONB compatible с current `_POI_WEIGHTS` const в
`backend/app/api/v1/parcels.py`:
- school 1.5, kindergarten 1.5, pharmacy 0.8, hospital 0.6
- shop_mall 1.2, shop_supermarket 1.0, shop_small 0.5
- park 1.8, bus_stop 0.3, metro_stop 1.5, tram_stop -0.5
## Idempotency
- BEGIN/COMMIT обёртка
- IF NOT EXISTS на CREATE TABLE/INDEX
- DROP TRIGGER IF EXISTS → CREATE TRIGGER (safe re-run)
- CREATE OR REPLACE FUNCTION (idempotent)
## Apply
```bash
psql postgresql://gendesign:...@localhost:15432/gendesign \
-f data/sql/90_user_weight_profiles.sql
```
После apply таблица inert (нет backend code yet). Sub-PR 2 добавит CRUD.
## Vault
`code/schemas/Schema_User_Weight_Profiles.md` — created (status:
ready_to_apply, full sub-PR plan).
