Kayos 36aba73f66 v0.3 step 3+4: AI plan generator + /list shopping aggregation 
- migrations 012 + 013: cauldron_meal_plan_slots + cauldron_pick_points
- db: list_plan_slots, save_plan_slots, delete_plan_slots, mark_plan_generated,
  clear_plan_generated, award_pick_points, enrich_plan_with_slots; scoreboard
  extended with points (sum from pick_points) and weeks_locked alias
- forge.generate_plan: sonnet prompt builds 7-day plan respecting picks,
  validates slot count + day uniqueness + slug-in-pool, fills picker_subs
  from ground-truth picks (model output is advisory)
- POST /api/plan/generate: race-safe (existing slots → 409 with plan),
  lock-aware (locked → 409), idempotent
- POST /api/plan/regenerate: re-roll for the original generator, gated by
  ownership + lock; wipes slots + pick_points then re-runs generate
- plan.html: generate CTA + 7 day cards with picker chips + AI reason +
  re-roll button (generator-only, pre-lock); scoreboard now shows points + wins
- /list: pulls plan slots, queries Mealie for ingredients, runs aggregator,
  renders 48px-tall checkbox shopping list with localStorage state per plan_id
- tests: 13 new tests across forge.generate_plan + /api/plan/generate routes
  + /list view + scoreboard SQL inspection. conftest+_testenv stub
  pymysql/oidc/foods at import time so tests run against module-level app
  without a live DB. Both pytest and `unittest discover` paths green (27/27).

Defers: bulk sterilizer admin (A1), foods dedupe (A2), Mealie shopping-list-
export (button rendered but disabled). 7-slot count is fixed at the
endpoint (no UI for slot-count selection yet).

README.md

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

Abby's phone (later: Kotlin app)
        │
        ▼
  cauldron (Flask, port 7790, LAN-only)
   ├─ Mealie API client  ─── recipes.sulkta.com  (source of truth)
   ├─ 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)
