# MealPlanner — Agent Handoff

You are taking over a project in mid-flight. Read `docs/ORIENTATION.md` first for the high-level. This file is the deep dive: what's real, what's stubbed, where the bodies are buried, and what to do next.

**Date of handoff: 2026-05-12. Last commits before handoff:**
```

## TL;DR

The system is **fully operational end-to-end** on the Woolery family's home network. Vote emails now show recipe images, descriptions, ingredient lists, cooking steps, estimated costs, and a shopping list preview. Peter confirmed the email looks polished; Julia's feedback pending.

**Match accuracy:** 10,140 AUTO + 3 AUTO_LLM matches. 22 ingredients remain unmatched (genuine Lucky CA catalog gaps: olive oil, dried spices, chickpeas, etc.).

**Next tasks:**
1. **Spoonacular enrichment (5 remaining)** — run `scripts/enrich_recipes_spoonacular.py` again; 5 recipes still need images (daily quota was hit on 2026-05-11)
2. **Phase 8 Feedback UI** — `feedback` table exists; no UI reads/writes it yet

## Infrastructure — READ THIS FIRST

### Access
- App: `http://100.108.224.12:8081` (WireGuard `wt0` interface)
- Ports 80 and 443 are owned by `lifemanager-caddy-1` on this host — do NOT use them
- Always use `docker compose --env-file .env.test` (never bare `docker compose`)

### Stack up
```bash
cd /home/peter/Projects/MealPlanner
docker compose --env-file .env.test up -d
```

### Applying Python code changes
`docker cp` alone is NOT enough — the running process caches modules. Always:
```bash
docker cp backend/app/path/to/file.py mealplanner-backend-1:/app/app/path/to/file.py
docker compose --env-file .env.test restart backend
```

### DB connection
```bash
docker compose --env-file .env.test exec -T db psql -U mealplanner -d mealplanner
```
DB user is `mealplanner` (not `postgres` — that role does not exist).

### Admin API auth
```
Authorization: Bearer test-admin-token
```
(NOT `X-Admin-Token` — it's a standard Bearer header. See `backend/app/security.py`.)

### Key env vars (`.env.test`)
```
EMAIL_BACKEND=sendgrid
SENDGRID_API_KEY=<real key>
APP_BASE_URL=http://100.108.224.12:8081
SESSION_PASSWORD=test-family-password
ADMIN_TOKEN=test-admin-token
```

---

## Family data (live, seeded)

- Family: **Woolery**, 4 members
- Adults: **Peter** (peter@research.bike) + **Julia** (julia@research.bike)
- 2 kids without email addresses (voting not required from them)
- Family profile + members are in the DB. Seed script: `scripts/seed_family.py` (safe to re-inspect; will exit early if profile already exists)

---

## What changed in this session

### MVP login + auth gating (committed in `feature/mvp-login`, merged to master)
- `frontend/src/pages/Login.tsx` — password form, calls `auth.login()`, redirects to `/`
- `frontend/src/App.tsx` — added `/login` route, Sign out button in nav
- `frontend/src/api/index.ts` — 401 interceptor redirects unauthenticated users to `/login`
- The frontend is **built and deployed** inside the Docker frontend container

### nginx (committed in `59a15a2`)
- Rewritten with Docker DNS resolver (`127.0.0.11 valid=10s`) to prevent IP caching after container restarts
- Port mapped to `8081:80` (ports 80/443 conflict with `lifemanager-caddy-1`)
- Proxy pattern: `set $var` forces per-request DNS resolution — without this, a backend restart causes 502s until nginx restarts too

### Vote email enrichment (`aeed2a4`)
Each recipe card in the Friday proposal email now shows:
- Recipe name
- Ingredient list (resolved from `Ingredient` table via UUID lookup — the JSONB stores `ingredient_id`, not `name`)
- Collapsible `<details>` block with numbered cooking steps (`recipe.instructions` ARRAY)
- Estimated cost (sum of top-confidence grocery matches)
- Vote button

### Shopping list email improvements (`aeed2a4`)
- Ingredients grouped under each recipe heading (was flat deduplicated list)
- Fixed field name: `match.grocery_item.current_price` (was `.price` — column doesn't exist)

### Ingredient matcher — full rewrite (`ac2b575`, `d7a3f5c`, `2373883`)

**Root cause of old failures:** the old matcher iterated grocery items and matched them against ingredient names using `fuzz.WRatio`. Long branded product names containing an ingredient word incidentally scored very high — "Pampers Baby Fresh Scent Wipes" → "Ginger, **Fresh**".

**New algorithm in `backend/app/services/matcher.py`:**

```
For each ingredient:
  1. Exact-name fast path: lowercase-trimmed dict lookup against all grocery names
     → confidence 1.000, skip fuzzy entirely (handles "Lime" → "Lime")
  2. Fuzzy: partial_token_sort_ratio against all grocery names (limit=100)
  3. For each candidate above threshold (0.82):
     a. 100% recall: all ingredient sig-words must appear in grocery sig-words
     b. Category exclusion: grocery must not have disqualifying words absent from ingredient
        (bread, chips, pasta, margarita, butter, soda, juice, tuna, rotisserie, etc.)
     c. Precision floor (0.45): ingredient sig-words / grocery sig-words ≥ 0.45
     d. Combined score = partial_score × precision
  4. Store best combined score via ON CONFLICT DO NOTHING (preserves manual overrides)
```

**Stop words** (stripped from sig-word sets): fresh, organic, whole, large, small, medium, low, free, light, dark, raw, dried, frozen, canned, extra, virgin, pure, natural, classic, style, boneless, skinless, lean, grain, long, jarred, roasted, smoked, cooked, and, with, for, the.

**Benchmark on Lucky CA weekly ad + full produce catalog (11,044 items):**
- Before: ~25% correct (Pampers→Ginger, Red Wine→Bell Pepper, Garlic Bread→Garlic)
- After: ~90%+ correct

**Current match quality for recipe ingredients:**
```
Garlic                → Fresh Garlic ($4.99)           ✓ confidence 1.0
Lime                  → Lime (no price — sold by each) ✓ confidence 1.0
Cilantro              → Cilantro, Fresh ($1.99)         ✓ confidence 1.0
Bell Pepper, Red      → Organic Red Bell Pepper ($2.49) ✓ confidence 1.0
Ground Beef, 85/15    → 85% Lean Ground Beef ($5.99)   ✓ confidence 1.0
Cheddar Cheese, Sharp → Sharp Cheddar Cheese ($10.99)  ✓ confidence 1.0
Ginger, Fresh         → Ginger Root ($3.99)             ✓ confidence 0.5
Ground Turkey         → Butterball Ground Turkey ($6.99) ✓ confidence 0.67
Soy Sauce             → Kikkoman Soy Sauce ($3.99)      ✓ confidence 0.67
Salt, Kosher          → Coarse Kosher Salt ($2.99)      ✓ confidence 0.67
Olive Oil             → — (Lucky CA has none in catalog)
Tortilla, Corn        → — (not in catalog this week)
```

### Scraper fix — save priceless produce (`2373883`)
`backend/app/scraper/lucky_ca_scraper.py` `map_product()` previously returned `None` for items with no price, skipping them. Fresh produce (garlic, limes) is sold by the each with no catalog price. Removed the price guard — items with `current_price=NULL` are now saved and matched.

---

## What is real (verified)

Everything in the prior HANDOFF (Phase 4 thin slice, Phase 5 orchestration, Phase 6 SendGrid, Phase 9 generation) is still real. Key additions:

### Lucky CA API (Swiftly) — full catalog accessible
The Swiftly API is the same for ALL product categories, not just the weekly ad:
- **Taxonomy**: `GET https://luckysupermarkets.com/categories?_data=root` — works without user cookies, returns JSON with `taxonomies` list of 17 top-level category slugs
- **Products per category**: `GET https://prod.swiftlyapi.net/search/api/v1/products/categories?cat=Product%2F{slug}&limit=10000&store=757` with `Authorization: Bearer <swiftly_jwt>`
- **JWT**: auto-minted via `backend/app/services/swiftly_auth.py` — no manual token needed
- **17 categories**: produce (660 items), meat_seafood (265), pantry (1000), dairy_eggs_cheese (1000), frozen_foods, beverage, snacks, bread_bakery, deli_counter, etc.
- Current scraper scrapes all 17 categories; produce items now saved even without price

### Matcher runs automatically
`backend/app/services/scraper_service.py` calls `run_match_job(db, source_filter="lucky_california")` after every successful scrape. If you change matcher code, restart the backend before re-scraping so the new code is loaded.

---

## What is stubbed or missing

### Recipe images (Phase 10 — approved, not started)
- `recipe.image_url` is NULL for all 107 recipes → no photos in vote emails
- **Approved plan:** Spoonacular API enrichment script (107 recipes × 1 call = fits 150/day free quota)
- API returns image URL + description + improved instructions

### Recipe descriptions
- `recipe.description` is NULL for all recipes → no blurb in vote emails
- Spoonacular enrichment solves this alongside images

### Olive Oil + Corn Tortillas (Lucky catalog gap)
- Lucky CA's Swiftly catalog has no standalone olive oil or plain corn tortillas
- These show "—" in shopping list — correct behavior (better than wrong match)
- **Approved plan:** Ollama LLM matcher as a second pass using Lucky's product search API (`luckysupermarkets.com/search/products?q=<ingredient>`) to find items outside the Swiftly weekly ad

### Phase 8 — Feedback UI (not started)
- `feedback` table exists; no UI reads/writes it

---

## Known caveats and traps

1. **Module caching.** `docker cp` without restart leaves old Python code running. Always restart backend after copying files.

2. **Bootstrap login hatch.** When no `family_profile` row exists, `auth.py` signs the literal string `"bootstrap"`. Woolery family is seeded so this is dormant. If DB is wiped, re-run `scripts/seed_family.py`.

3. **DB user is `mealplanner`.** `psql -U postgres` fails. Always use `psql -U mealplanner -d mealplanner`.

4. **Matcher ON CONFLICT DO NOTHING.** Manual matches (`source='manual'`) are never overwritten. If you set a manual match and want the auto-matcher to take over, delete the manual row first.

5. **`weekly_run` idempotency.** Each step sets its timestamp column on completion; re-firing is a no-op. To re-trigger a step, set its timestamp to NULL:
   ```sql
   UPDATE weekly_run SET finalized_at = NULL, status = 'running';
   ```

6. **Scraper `items_scraped` count appears stuck at 0 during run.** The count is only written on completion (26–60s). The status field stays `started` until then.

7. **`limit=10000` in Swiftly API.** Pantry and dairy categories return exactly 1000 items each — suspected server-side cap below our limit. Either multiple pages exist (no offset param observed) or those are genuine catalog sizes. Produce (660) and meat_seafood (265) look complete.

8. All prior caveats in the 2026-05-08 HANDOFF still apply (SQLEnum, transactional fixtures, `alembic downgrade base`, etc.).

## Suggested next moves

### 1. Spoonacular recipe enrichment (images + descriptions)

Free tier: 150 req/day. 107 recipes = one run, one commit.

Plan:
- Write `scripts/enrich_recipes_spoonacular.py`
- For each recipe: `GET https://api.spoonacular.com/recipes/search?query={name}&apiKey=…` → pick best match → fetch details → update `recipe.image_url`, `recipe.description`
- `SPOONACULAR_API_KEY` needs to be added to `.env.test`
- Run once: `docker cp scripts/enrich_recipes_spoonacular.py mealplanner-backend-1:/app/ && docker compose --env-file .env.test exec backend python /app/enrich_recipes_spoonacular.py`

### 2. Ollama LLM matcher (Olive Oil, Corn Tortillas, etc.)

Approved architecture:
```
For each ingredient with no match OR confidence < 0.5:
  1. Query Lucky product search: GET https://luckysupermarkets.com/search/products?q={ingredient}
     (reverse-engineer the JSON API from that page)
  2. Extract top 5-10 results
  3. POST to Ollama: "I need {ingredient} for a recipe. Which is the best match?
     Options: [list]. Answer with just the product name or 'none'."
  4. Store result as source='auto_llm' in ingredient_grocery_match
```

Peter uses **Ollama Cloud** for LLM inference. Confirm the API endpoint + model to use.
A small model (llama3.2:3b or mistral:7b) handles "pick the right produce item" accurately.

### 3. Natural Friday cycle

Next Friday at 02:00 PT the scheduler runs automatically. No action needed. All fixes in this session are committed and the new matcher + scraper will run.

## Final words

Trust the tests. Trust the live runs. Don't trust prose claims that something is "complete" without running the verification gate yourself.

**Last updated: 2026-05-12** — Spoonacular enrichment (102/107 recipes), LLM matcher built (Ollama Cloud kimi-k2.6), AUTO matcher improved (plural normalization, precision floor 0.45→0.30), vote email confirmed polished by Peter. Next: run Spoonacular script again for 5 remaining recipes; Phase 8 Feedback UI.
