Kayos f74a627ac7 Step 2: re-key cauldron's food metadata by mealie_food_id
Aligns cauldron's data layer with the architectural rule "Mealie owns
canonical food names; cauldron only owns cooking metadata Mealie can't
store". The old parallel name catalog (cauldron_foods, 2462 noisy USDA
rows + ~229 Sonnet-curated names) was always going to drift from
Mealie's foods table over time. Now metadata follows Mealie's UUID, so
when Cobb merges or renames a food in Mealie the density+unit_class
travels with it automatically.

Schema:
- New table cauldron_food_metadata (migration 017): primary key is
  mealie_food_id VARCHAR(64); columns are density_g_per_ml,
  common_size_g, default_unit_class, category, source enum (seed /
  claude / manual), notes JSON.
- cauldron_foods table stays untouched in this step (Step 4 drops it
  after the backfill ledger has been verified in production).

Code:
- cauldron/foods.py rewritten:
  - get_metadata_by_food_id(db, mealie_food_id) — primary read
  - upsert_metadata(...) — write keyed by mealie_food_id
  - fetch_and_persist(db, mealie_food_id, food_name, forge) — Sonnet
    fallback, persists keyed by id
  - backfill_seed_from_legacy(db, mealie) — one-time migration helper
    called at app boot when metadata table is empty. Walks Mealie's
    foods, looks up each in legacy cauldron_foods by name/plural/alias,
    copies density into the new table keyed by Mealie's id. Returns
    {matched, missed, total_mealie} stats.
  - Legacy shims (search_food, upsert_claude_food, load_seed_if_empty)
    kept as no-ops so server boot doesn't break before full cutover.

- cauldron/aggregator.py:
  - Ingredient.mealie_food_id new optional field
  - aggregate() now keys by mealie_food_id when present, falls back to
    normalized name. Verified with rice-from-3-recipes synthetic:
    same id → consolidates to "2.25 lb rice" single line as before.
  - foods_lookup callable signature changed to (name, food_id) — id is
    primary, name is for display + Sonnet fallback.

- cauldron/server.py:
  - /list view captures Mealie's food.id from each recipe ingredient
    and threads it through the Ingredient. foods_lookup now does an
    id-keyed cauldron_food_metadata read; on miss with a known id,
    calls forge.fetch_food_info and persists. When food.id is missing
    (ingredient still in note form, no Mealie row linked), returns
    None and aggregator falls back to name grouping.
  - Boot: replaces the USDA seed loader with a one-time backfill of
    legacy cauldron_foods → cauldron_food_metadata via the system
    Mealie token. Runs only when metadata table is empty.

Net effect: rice in 3 recipes that all link to the same Mealie food
row now group by UUID, not by lowercased name. When Mealie's foods
get cleaned up (Step 3 consolidator), cauldron's metadata follows
because the ids are stable. Foundation for the consolidator is now
in place.

cauldron

Mealie-backed AI meal planner + shopping list for the family. LAN-only, internal tool. Mealie at recipes.sulkta.com is the source of truth for recipes / meal plans / shopping lists; cauldron is the AI layer + Abby's branded UI on top.

Status

v0.1 — backend bones (current). Ingredient sterilizer endpoint working. No UI yet; bearer-auth API only. Frontend + Authentik OIDC arrives in v0.2. Native Kotlin Android in v0.5.

Surface (v0.1)

GET  /healthz                              liveness + clawdforge upstream
GET  /api/recipes                          list Mealie recipes (paginated)
POST /api/sterilize/preview/<slug>         dry-run AI parse, return proposals
POST /api/sterilize/apply/<slug>           write parses back to Mealie

All routes except /healthz require Authorization: Bearer <ADMIN_BEARER>.

Architecture

   ├─ clawdforge client  ─── 192.168.0.5:8800   (claude -p runner)
   └─ Authentik OIDC (v0.2)

cauldron does NOT hold its own database in v0.1 — all state lives in Mealie. A small Postgres/MariaDB schema lands in v0.2 for Abby-specific prefs + chat history.

Ingredient sterilizer

Mealie's CRF parser is mediocre. Cobb's hand-typed recipes have lots of free-form quantity strings ("about 2 cups cooked white rice", "1 small handful kale", "a pinch of salt") that don't aggregate cleanly into a shopping list.

The sterilizer batches all ingredients of one recipe into a single Sonnet call (via clawdforge), gets back parallel structured parses, then on apply links each parse to existing Mealie food/unit records (creating any missing by name) and PUTs the recipe back.

Preview is non-destructive — review proposals before apply.

# Dry-run preview
curl -sS -X POST -H "Authorization: Bearer $ADMIN_BEARER" \
  http://192.168.0.5:7790/api/sterilize/preview/spaghetti-bolognese | jq .

# Apply (creates missing foods/units by default)
curl -sS -X POST -H "Authorization: Bearer $ADMIN_BEARER" \
  http://192.168.0.5:7790/api/sterilize/apply/spaghetti-bolognese | jq .

Deploy

  1. ssh lucy
  2. cd /mnt/user/appdata && git clone <gitea-url> cauldron && cd cauldron/build (or wherever the deploy convention lands)
  3. Drop .env at /mnt/cache/appdata/secrets/cauldron.env (chmod 600 root:root)
    • CLAWDFORGE_TOKEN is already populated by the bootstrap (see memory/2026-04-28.md)
    • MEALIE_API_TOKEN — mint at recipes.sulkta.com → user → API tokens
    • ADMIN_BEARER — pick 32 bytes of entropy
    • SECRET_KEY — 32 bytes for Flask sessions
  4. docker compose up -d --build
  5. Smoke: curl http://192.168.0.5:7790/healthz

Roadmap

  • v0.1 ✓ — sterilizer backend + Flask shell
  • v0.2 — Authentik OIDC, Abby-branded web UI, palette CSS, postgres for prefs
  • v0.3 — meal plan generator (week → Mealie meal plan write)
  • v0.4 — shopping list aggregator (read meal plan → consolidated grocery list)
  • v0.5 — native Kotlin + Compose Android app (read-only shopping list + plan view)
