+# M12 — Idea entity + Grill/Plan Claude jobs
+
+## Context
+
+Scrum4Me ondersteunt `Todo` als lichtgewicht voorstel-laag, en kan dat handmatig promoveren naar PBI/Story. Dat slaat het *denkproces* niet vast: waarom werd iets een PBI, welke alternatieven zijn afgewogen, welke randvoorwaarden waren er.
+
+Doel: een nieuw concept **Idee** dat:
+- werkt als een Todo (top-level lijst, privé per gebruiker), met een **Grill Me**- en **Make Plan**-knop;
+- via de bestaande Claude-job/worker-infrastructuur een gestructureerd plan oplevert;
+- het hele planningsproces vastlegt (Q&A, beslissingen, grill-md, plan-md, link naar PBI);
+- na goedkeuring deterministisch materialiseert tot PBI + stories + taken (incl. `implementation_plan`).
+
+## Vastgelegde keuzes (uit grill-sessie)
+
+1. **UI-plek**: top-level `/ideas`, naast `/todos`.
+2. **Auth-scope**: strikt `user_id`-only (privé, ook ná `PLANNED`). Geen `productAccessFilter` op idea-acties; geen `pbi.idea_id`-veld nodig.
+3. **Product-binding**: een idee mag bestaan zonder product, maar **Grill Me** én **Make Plan** vereisen een product met `repo_url` (de worker leest sources/docs uit de repo). `claude_jobs.product_id` blijft NOT NULL.
+4. **Executie-model**: bestaand worker-model. `ClaudeJob{kind:IDEA_*}` QUEUED → lokale Claude-CLI claimt via `wait_for_job`. Knoppen zijn **disabled als `connectedWorkers === 0`** (exact zoals `solo/task-detail-dialog.tsx`).
+5. **Skill-afhankelijkheid**: **embedded prompts** in `lib/idea-prompts/{grill,make-plan}.md`; meegestuurd in payload. Geen externe `anthropic-skills:grill-me`-plugin-vereiste op de worker.
+6. **Make-Plan flow**: preview-en-bevestigen. Job produceert `Idea.plan_md`, status → `PLAN_READY`. Aparte knop **"Materialiseer plan"** parseert md → entiteiten in één Prisma-transactie, status → `PLANNED`.
+7. **Plan-md formaat**: YAML-frontmatter (structuur) + markdown-body (overwegingen, alternatieven, vrije reasoning).
+8. **Make-Plan-job**: single-pass (geen `ask_user_question`). Twijfels → terug naar grill (append-context).
+9. **Backward transitions**:
+   - Re-grill vanuit `GRILLED`/`PLAN_READY`: nieuwe `IDEA_GRILL`-job met **append-context** (oude `grill_md` als input); oude versie naar `IdeaLog{type:GRILL_RESULT}` als history.
+   - Re-plan vanuit `PLAN_READY`: idem voor `plan_md`.
+   - PBI-verwijdering vanuit `PLANNED`: **expliciete user-actie "Re-link plan"** (geen DB-trigger). Zet `pbi_id=null`, status `PLAN_READY`.
+   - Failed grill/plan: dedicated states **`GRILL_FAILED` / `PLAN_FAILED`** (zichtbaar voor user), niet stilzwijgend resetten.
+10. **Logging-model**: `IdeaLog` smal (`DECISION | NOTE | GRILL_RESULT | PLAN_RESULT | STATUS_CHANGE | JOB_EVENT`). Q&A blijft uitsluitend in `claude_questions`. Timeline-tab in UI doet `UNION ALL` over beide bronnen.
+11. **Opslag md-bestanden**: alleen DB (`Idea.grill_md`, `Idea.plan_md`). Geen auto-commit naar repo (zou strict-private auth-keuze ondergraven). UI biedt **"Download .md"**.
+12. **Editability**: beide md's bewerkbaar door user in hun ready-states (`GRILLED` voor grill_md, `PLAN_READY` voor plan_md). Bij `PLANNED`: read-only. Yaml-frontmatter wordt zod-gevalideerd-on-save voor `plan_md`.
+13. **Promotie vanuit Todo**: nieuwe `promoteTodoToIdeaAction` (Todo → DRAFT-Idea + Todo wordt `archived=true`). Bestaande Todo→PBI/Story-acties blijven onaangetast.
+14. **Demo-policy** (3-laag, zoals Todo): create/edit/archive **mag**; Grill / Make Plan / Materialiseer / promote-from-Todo zijn **geblokkeerd** (proxy.ts 403 + `session.isDemo`-guard + `<DemoTooltip>`).
+15. **Idea-code**: `Idea.code = "IDEA-{nnn}"`, `@@unique([user_id, code])`, counter op `User.idea_code_counter`.
+16. **Realtime-store**: nieuwe `stores/idea-store.ts`. `connectedWorkers` direct selecten via `useSoloStore(s => s.connectedWorkers)` (lift naar shared store is opvolg-refactor).
+17. **Sidebar**: nieuwe entry **Ideeën** (`Lightbulb`-icon) direct boven Todo's.
+18. **Q&A-expiry**: 24h aanhouden (consistent met bestaand). Verlopen → re-grill (append-context).

+
+## Server-laag
+
+### Schemas + helpers
+- `lib/schemas/idea.ts` — `ideaCreateSchema`, `ideaUpdateSchema`, `ideaPlanMdFrontmatterSchema`.
+- `lib/idea-status.ts` — DB-enum ↔ API-string mapping.
+- `lib/idea-plan-parser.ts` — synchroon: `parsePlanMd(md): ParsedPlan | ZodError`. Gebruikt `yaml`-package + zod.
+- `lib/idea-code.ts` — atomair `nextIdeaCode(userId)` via Prisma-transactie.
+
+### Embedded prompts
+- `lib/idea-prompts/grill.md` — eigen scrum4me-versie. Instrueert: gebruik `ask_user_question` MCP, schrijf via `update_idea_grill_md` aan eind.
+- `lib/idea-prompts/make-plan.md` — strict yaml-frontmatter-format. Instrueert: lees `grill_md`, gebruik repo-files, **geen vragen**, eindig met `update_idea_plan_md`.
+
+### Server actions — `actions/ideas.ts`
+Volg `docs/patterns/server-action.md`: auth → demo-check → zod → user-id-scope-check → write → `revalidatePath`.
+
+- `createIdeaAction(input)` — `nextIdeaCode(userId)`, status `DRAFT`.
+- `updateIdeaAction(id, input)` — alleen `DRAFT|GRILL_FAILED|GRILLED|PLAN_FAILED|PLAN_READY`.
+- `archiveIdeaAction(id)` / `unarchiveIdeaAction(id)`.
+- `deleteIdeaAction(id)` — geweigerd als `pbi_id` gevuld.
+- `updateGrillMdAction(id, md)` — alleen in `GRILLED|PLAN_READY`. Logt `IdeaLog{NOTE}`.
+- `updatePlanMdAction(id, md)` — alleen in `PLAN_READY`. Eerst `parsePlanMd(md)`; bij parse-fail → 422 met line-info.
+- `startGrillJobAction(id)` — vereist product met `repo_url`, `connectedWorkers > 0`. `ClaudeJob{kind:IDEA_GRILL, idea_id, product_id, QUEUED}`. Status → `GRILLING`. Demo: 403.
+- `startMakePlanJobAction(id)` — vereist `GRILLED|PLAN_FAILED|PLAN_READY` voor re-plan, product met repo, worker. Status → `PLANNING`. Demo: 403.
+- `cancelIdeaJobAction(id)` — actieve job CANCELLED, idea-status terug naar vorige.
+- `materializeIdeaPlanAction(id)` — `PLAN_READY` → `parsePlanMd` → Prisma-`$transaction`:
+  1. Counters incrementeren (PBI/Story/Task).
+  2. INSERT PBI + N stories + M tasks (incl. `implementation_plan`).
+  3. UPDATE idea: `pbi_id`, `status:PLANNED`.
+  4. INSERT `IdeaLog{type:PLAN_RESULT, metadata}`.
+  Rollback bij ANY fail. Demo: 403.
+- `relinkIdeaPlanAction(id)` — alleen als `status===PLANNED && pbi_id===null`. Status → `PLAN_READY`.
+- `downloadIdeaMdAction(id, kind: 'grill'|'plan')` — server returnt md.
+
+### Promote van Todo → Idea
+- `actions/todos.ts`: nieuwe `promoteTodoToIdeaAction(todoId)` — auth + demo + scope. Maakt Idea (DRAFT) met title/description; zet Todo `archived=true`. Demo: 403.
+
+### REST-routes
+- `app/api/ideas/route.ts` (GET, POST) en `app/api/ideas/[id]/route.ts` (GET, PATCH).
+

+### Nieuwe tools
+- `get_idea_context(idea_id)` — `{idea, product, repo_url, grill_md_so_far, open_questions, prompt_text}`.
+- `update_idea_grill_md(idea_id, markdown)` — schrijft veld; status → `GRILLED`; logt `IdeaLog{GRILL_RESULT}`.
+- `update_idea_plan_md(idea_id, markdown)` — schrijft veld; parser draait server-side; status → `PLAN_READY` of `PLAN_FAILED`.
+- `log_idea_decision(idea_id, type, content, metadata?)` — types: `DECISION | NOTE`.
+
+### Uitbreiding bestaande tools
+- `ask_user_question`: contract uitbreiden — exact één van `story_id` of `idea_id`.
+- `wait_for_job`: response uitbreiden:
+  - `kind: 'TASK_IMPLEMENTATION' | 'IDEA_GRILL' | 'IDEA_MAKE_PLAN'`
+  - bij `IDEA_*`: `idea`, `product`, `repo_url`, `prompt_text`.
+- `update_job_status`: bij `failed` voor IDEA_*-jobs zet idea-status `GRILL_FAILED` / `PLAN_FAILED`.
+
+### Schema-drift
+- `docs/runbooks/mcp-integration.md:62`: schema-drift-watchdog moet groen zijn vóór merge. MCP-server-PR parallel.
+
+## Realtime-laag
+
+- `app/api/realtime/notifications/route.ts` — idea-questions alleen aan `idea.user_id === session.user_id`.
+- `app/api/realtime/solo/route.ts` — `JobPayload` uitbreiden met `kind` en `idea_id`. Idea-jobs op `user_id`.

+- Sidebar-entry: `Lightbulb`, label "Ideeën", boven Todo's.
+
+### Componenten — `components/ideas/`
+- `idea-list.tsx` — TanStack Table; kolommen code/title/product/status/archived. Bulk-archive.
+- `idea-row-actions.tsx` — Grill Me / Make Plan / Materialiseer / Edit / Archive met disabled-rules.

+## Implementatievolgorde
+
+1. **DB & migratie**
+2. **Lib + schemas + prompts**
+3. **Server actions + Todo-promote**
+4. **REST + proxy demo-laag**
+5. **Realtime SSE + idea-store**
+6. **MCP-server tools (extern repo, parallel)**
+7. **UI lijst + row-actions**
+8. **UI detail + dialog + tabs**
+9. **UI promote-from-Todo + sidebar-entry**
+10. **End-to-end smoke + docs**
+
+## Verificatie
+
+```bash
+npm run lint && npm test && npm run build
+```
+
+End-to-end:
+1. `npm run dev` + lokale Claude-CLI met `wait_for_job`-loop.
+2. Maak idee, koppel aan product. Status `DRAFT`.
+3. Grill Me → vragen via answer-modal → `update_idea_grill_md` → `GRILLED`.
+4. Edit grill_md handmatig → `IdeaLog{NOTE}`.
+5. Make Plan → `update_idea_plan_md` → `PLAN_READY`.
+6. Yaml-fout in plan_md → save geblokkeerd.
+7. Materialiseer → PBI + stories + taken in transactie. `idea.pbi_id` gezet, `PLANNED`.
+8. PBI verwijderen → "Re-link plan"-banner → `PLAN_READY`.
+9. Demo-test: knoppen geblokkeerd via DemoTooltip + 403.
+10. Failure-test: kill worker → `GRILL_FAILED`/`PLAN_FAILED`.
+11. Promote-test: Todo → "Promote naar Idee" → DRAFT-Idea, Todo archived.
+
+## Open punten (niet-blokkerend)
+
+- Concrete copy-finetuning van prompt-md's tijdens implementatie.
+- Lift `connectedWorkers` naar gedeelde `worker-presence-store` (opvolg-refactor).
+- Optionele "Commit plan_md naar repo"-knop (buiten v1).

 ## Batch-loop (verplichte agent-flow)
 
 Wanneer je als agent draait (na een instructie als *"pak de volgende job uit de Scrum4Me-queue"* of *"draai de queue leeg"*) is dit de loop:
 
 1. `wait_for_job` aanroepen.
-2. Job uitvoeren volgens het meegegeven `implementation_plan`.
+2. Switch op `kind`:
+   - `TASK_IMPLEMENTATION`: voer uit volgens het meegegeven `implementation_plan` (zoals altijd — branch, code, commit, push, verify_task_against_plan).
+   - `IDEA_GRILL`: laad `prompt_text` als gids; gebruik `ask_user_question` / `get_question_answer` voor de Q&A-loop; eindig met `update_idea_grill_md`.
+   - `IDEA_MAKE_PLAN`: laad `prompt_text` + `idea.grill_md`; **stel geen vragen**; produceer strict yaml-frontmatter; eindig met `update_idea_plan_md`.
 3. `update_job_status('done'|'failed')` aanroepen.
 4. **Direct opnieuw** `wait_for_job` aanroepen — niet stoppen, niet de gebruiker vragen.
 5. Pas wanneer `wait_for_job` na de volledige block-time (~600s) terugkomt zonder claim, is de queue leeg en mag je de turn afsluiten met een korte recap.

+## URL- of state-pattern
+
+**Afwijking van generieke spec:** Idee gebruikt een **dedicated route** `/ideas/[id]` ipv een modal-dialog. Reden: het detail-scherm is rijker dan een modal kan dragen (4 tabs incl. md-editor + timeline) en de planningsgeschiedenis is een leesbaar artifact dat verdiend om bookmarkable te zijn.
+
+- **Lijst-create**: state-based inline form bovenaan `/ideas` lijst (`IdeaList.showCreate`).
+- **Detail / edit**: route `/ideas/[id]` met tab-switcher via query-param (`?tab=idee|grill|plan|timeline`).
+- **Geen modal**: dus geen `Cmd/Ctrl+Enter`-submit op de detail-form (alleen op md-editor); `Esc` doet niets in het detail-scherm.
+
+---
+
+## Tabs (alleen op detail-route)

+
+## Special behaviors
+
+### IdeaMdEditor
+
+- **Cmd/Ctrl+S** triggert save (alleen in editor, niet in detail-form).
+- **localStorage draft** per `(idea_id, kind)`: lazy read-on-mount via `useState(() => readSeed(...))` om setState-in-effect te vermijden. Drift met server → toast info bij restore.
+- **Live yaml-validate** voor plan-kind: `useMemo(() => parsePlanMd(value))` → derived state, geen useEffect.
+- **Submit-errors** los van validation-errors in state — server-side details overschrijven client-side validate als die er zijn.
+
+### IdeaPbiLinkCard
+
+- Drie states: PLANNED+pbi (groene link), PLANNED+pbi-null (oranje banner met Re-link knop), niet-PLANNED (return null).
+
+### Status badges
+
+- Status-tokens via `lib/idea-status-colors.ts` → `getIdeaStatusBadge(status)` → `{ label, classes, pulse? }`.
+- `GRILLING` en `PLANNING` → `animate-pulse` om "actief" te signaleren.
+
+### Connected workers
+
+- `IdeaRowActions` leest `useSoloStore(s => s.connectedWorkers)` (M12 grill-keuze 16 — geen lift naar gedeelde store voor v1).
+- Zonder worker: Grill / Make Plan disabled met tooltip "Geen Claude-worker actief". Materialiseer is server-side synchroon en heeft géén worker nodig.
+
+---
+
+## Realtime
+
+SSE-stream `/api/realtime/notifications` levert idea-events (M12 T-502). Routing in `lib/realtime/use-notifications-realtime.ts`:
+
+- `claude_job_*` payloads met `kind=IDEA_*` → `useIdeaStore.handleIdeaJobEvent`
+- `entity:'question'` payloads met `idea_id` set → `useIdeaStore.handleIdeaQuestionEvent`
+- Story-questions blijven in `useNotificationsStore`
+
+`useIdeaStore` houdt optimistic state: `jobByIdea`, `ideaStatuses`, `openQuestionsByIdea`. Voor de detail-pagina is de server-state na `router.refresh()` source-of-truth — de store is een UI-cache.
+
+---
+
+## Test-fixtures
+
+- `__tests__/actions/ideas-crud.test.ts` (39 cases) — alle CRUD + job-trigger + materialize + relink paden
+- `__tests__/api/ideas.test.ts` (13 cases) — REST-laag
+- `__tests__/stores/idea-store.test.ts` (7 cases) — Zustand event-handling
+- `__tests__/lib/idea-status.test.ts` (15+ cases) — status mappers + transition guards
+- `__tests__/lib/idea-schemas.test.ts` (16+ cases) — zod-validatie
+- `__tests__/lib/idea-plan-parser.test.ts` (6 cases) — yaml-frontmatter
+- `__tests__/proxy/demo-guard.test.ts` (9 cases) — incl. 3 idea-cases

+
+> Deze prompt wordt door `wait_for_job` meegestuurd in de payload van een
+> `IDEA_GRILL`-job en gevolgd door de Claude-CLI-worker. Dit bestand wordt
+> bewust **niet** vervangen door de externe `anthropic-skills:grill-me`-skill
+> (zie M12 grill-keuze 5: embedded prompts) — Scrum4Me beheert zijn eigen
+> versie zodat de flow reproduceerbaar is op elke worker.
+
+---
+
+Je bent een **grill-agent** voor Scrum4Me-idee `{idea_code}` (titel:
+`{idea_title}`).
+
+Je context (meegegeven in `wait_for_job`-payload):
+
+- `idea`: het volledige idee-record incl. eventueel bestaande `grill_md`
+- `product`: het gekoppelde product (incl. `repo_url` en `definition_of_done`)
+- `repo_url`: lokale repo om te lezen (worker bevindt zich daar al)
+
+## Doel
+
+Het idee zó concretiseren dat de **make-plan**-fase er een implementeerbaar
+PBI van kan maken. Eindresultaat is een markdown-document dat je via
+`mcp__scrum4me__update_idea_grill_md` opslaat.
+
+## Werkwijze (loop, één vraag per cyclus)
+
+1. Lees de huidige `idea.title`, `idea.description`, en (indien aanwezig)
+   `idea.grill_md` — bij re-grill bouw je voort op wat er al staat, je gooit
+   het niet weg.
+2. Verken de repo voor context: `README`, `docs/`, `package.json`, en relevante
+   source-bestanden. Gebruik `Read`/`Grep`/`Glob` zoals normaal.
+3. Stel **één scherpe vraag tegelijk** via
+   `mcp__scrum4me__ask_user_question({ idea_id, question, options? })`. Wacht
+   op het antwoord (`mcp__scrum4me__get_question_answer` of `wait_seconds`).
+4. Verwerk het antwoord: log belangrijke beslissingen via
+   `mcp__scrum4me__log_idea_decision({ idea_id, type: 'DECISION'|'NOTE',
+   content })`.
+5. Herhaal tot je voldoende hebt voor een PBI (zie stop-conditie).
+6. Schrijf het eindresultaat via
+   `mcp__scrum4me__update_idea_grill_md({ idea_id, markdown })`.
+7. Roep `mcp__scrum4me__update_job_status({ job_id, status: 'done', summary })`.
+
+## Stop-conditie
+
+Je hebt genoeg wanneer je markdown bevat:
+
+- **Titel + scope** (1–3 zinnen)
+- **Minimaal 3 acceptatiepunten** (gedrag dat zichtbaar moet werken)
+- **Minimaal 1 risico/onbekende** (technisch, scope, afhankelijkheden)
+- **Open eindjes** (wat opzettelijk **niet** in v1 zit)
+
+Stop óók als de gebruiker expliciet zegt "klaar" / "genoeg" / "ga door".
+
+## Output-format (strikt)
+
+```markdown
+# Idee — {korte titel}
+
+## Scope
+…
+
+## Acceptatie
+- AC 1
+- AC 2
+- AC 3
+
+## Risico's & onbekenden
+- Risico 1
+- Onbekende 2
+
+## Open eindjes (niet in v1)
+- …
+```
+
+## Vraag-richtlijnen
+
+- **Scherp & specifiek**, geen open "wat denk je ervan?".
+- Bij twijfel: bied **multi-choice** via `options: ["A", "B", "C"]`.
+- Stel **één vraag per cyclus** — niet meerdere geneste.
+- Vermijd vragen waarvan het antwoord uit de repo te lezen is — lees zelf.
+- Geen meta-vragen ("zal ik nog meer vragen?"). Beslis zelf wanneer je stopt.
+
+## Foutgevallen
+
+- Vraag verloopt (24h): roep `update_job_status('failed', error: 'question expired')`.
+- Repo niet leesbaar: roep `update_job_status('failed', error: 'repo access')`.
+- Gebruiker annuleert via UI: job wordt door server op CANCELLED gezet; je krijgt geen verdere antwoorden — sluit netjes af.
+
+## Voorbeeld-vraag
+
+```
+ask_user_question({
+  idea_id,
+  question: "Moet 'Plant-watering reminder' alleen lokale notifications doen, of ook web-push?",
+  options: ["Alleen lokaal (eenvoud)", "Web-push (multi-device)", "Beide"],

+> `IDEA_MAKE_PLAN`-job. Single-pass, **stel geen vragen** (zie M12 grill-keuze
+> 8). Twijfels → terug naar grill via UI.
+
+---
+
+Je bent een **planning-agent** voor Scrum4Me-idee `{idea_code}`.
+
+Je context (meegegeven in `wait_for_job`-payload):
+
+- `idea.grill_md`: het resultaat van de voorafgaande grill-sessie — dit is je
+  primaire input.
+- `idea.plan_md`: bij re-plan bevat dit het vorige plan; gebruik als
+  referentie.
+- `product`: gekoppeld product met `repo_url`, `definition_of_done`,
+  bestaande architectuur in repo.
+
+## Doel
+
+Eén `plan_md` produceren die je via `mcp__scrum4me__update_idea_plan_md`
+opslaat. Dit document wordt later **deterministisch** geparseerd door de
+server-side `parsePlanMd` (zie `lib/idea-plan-parser.ts`) en omgezet in
+PBI + stories + taken via `materializeIdeaPlanAction`.
+
+## Werkwijze (single-pass)
+
+1. Lees `idea.grill_md` volledig.
+2. Verken de repo voor patronen, bestaande modules, en `docs/`-structuur.
+3. Bouw het plan op in de **strikte format** hieronder.
+4. Roep `mcp__scrum4me__update_idea_plan_md({ idea_id, markdown })`.
+5. Roep `mcp__scrum4me__update_job_status({ job_id, status: 'done', summary })`.
+
+## STEL GEEN VRAGEN
+
+`mcp__scrum4me__ask_user_question` is in deze fase **verboden**. Als je
+informatie mist die je nodig hebt om het plan compleet te maken, schrijf je
+plan met je beste aanname en documenteer je in de **Body** (zie hieronder)
+welke aannames je hebt gemaakt. De gebruiker beoordeelt het plan in `PLAN_READY`
+en kan dan handmatig editen of een re-grill triggeren.
