+# CharacterGarden — Iterative Implementation Plan (Updated)
+
+## Planning Rules
+
+Work in small, reviewable steps.
+
+After each completed step:
+
+1. Update thoughts.md
+2. Record files changed
+3. Record assumptions made
+4. Record next step
+5. Do not skip ahead unless the current step is complete
+
+Do not redesign the project without updating this plan.
+
+---
+
+# Phase 0 — Completed Baseline
+
+Status: COMPLETE
+
+- Contracts are established under app/src/contracts/
+- Deterministic truth engine is active
+- Rulebook-driven validation is active and editable
+- Core actions supported: inspect, move, open, take, introduce, describe, transfer
+- take createIfMissing path implemented with rulebook authorization
+- transfer action implemented with ownership/location checks
+- Turn orchestration moved behind turn manager seam
+- Interpreter contract and first interpreter module created
+- Docker container builds are passing for app and frontend
+
+## Phase 0 Structural Cleanup (April 2026) — COMPLETE
+
+- Deleted turns/processTurn.ts (was a pointless shim over runTurnManager)
+- Deleted truthEngine.ts (was a thin wrapper over rulebookEngine.validateWithRulebook)
+- Extracted world/seedWorld.ts — seed world logic out of app.ts; app factory is now lean
+- Fixed db.listTurns() to return real actions and validation results (previously always empty arrays)
+- Fixed worldState.rulebookId persistence — active rulebook now survives restarts
+- Generalized has_<item_id> in applyActions — no longer hardcoded to key_1 only
+
+---
+
+# Phase 1 — Intent Interpreter Boundary Hardening
+
+Status: IN PROGRESS
+
+## Step 1.1 — Strict interpreter envelope validation
+
+Goal:
+
+- Validate InterpreterOutput shape before it reaches validation/mutation.
+- Reject malformed interpreter payloads deterministically.
+
+Target files:
+
+- app/src/contracts/intent.ts
+- app/src/interpreter/interpretTurn.ts
+- app/src/turns/turnManager.ts
+
+## Step 1.2 — Clarification model expansion
+
+Goal:
+
+- Add structured clarification options and optional entity candidates.
+- Distinguish unrecognized-intent from reference ambiguity consistently.
+
+Target files:
+
+- app/src/contracts/intent.ts
+- app/src/interpreter/interpretTurn.ts
+
+## Step 1.3 — API compatibility for unresolved turns
+
+Goal:
+
+- Ensure /api/turn returns interpreter status and clarification payload reliably.
+- Keep existing fields backward-compatible for current frontend behavior.
+
+Target files:
+
+- app/src/turns/processTurn.ts
+- app/src/index.ts
+
+---
+
+# Phase 2 — Turn Trace and Persistence Enrichment
+
+Status: NOT STARTED
+
+## Step 2.1 — Persist interpreter envelope per turn
+
+Goal:
+
+- Persist interpreter status, diagnostics, and clarification metadata.
+
+Target files:
+
+- app/src/db.ts
+- app/src/contracts/turn.ts
+- app/src/turns/turnManager.ts
+
+## Step 2.2 — Extend read models and API snapshots
+
+Goal:
+
+- Include interpreter trace data in turn history returned by /api/state.
+
+Target files:
+
+- app/src/db.ts
+- app/src/app.ts
+- app/src/index.ts
+
+## Step 2.3 — Frontend turn inspector updates
+
+Goal:
+
+- Display interpreter status and clarification prompts in timeline and latest result.
+
+Target files:
+
+- frontend/src/App.tsx
+
+---
+
+# Phase 3 — Resolver Plug-in Architecture
+
+Status: COMPLETE
+
+## Step 3.1 — Introduce resolver interface
+
+Goal:
+
+- Define a stable resolver interface that returns InterpreterOutput.
+
+Target files:
+
+- app/src/interpreter/resolveIntent.ts (new)
+- app/src/interpreter/interpretTurn.ts
+
+## Step 3.2 — Deterministic adapter extraction
+
+Goal:
+
+- Move current parser-backed behavior into a deterministic adapter.
+
+Target files:
+
+- app/src/interpreter/adapters/deterministicResolver.ts (new)
+- app/src/interpreter/interpretTurn.ts
+
+## Step 3.3 — LLM resolver adapter
+
+Goal:
+
+- Add LLM adapter behind config, without making it authoritative over deterministic validation.
+
+Target files:
+
+- app/src/interpreter/adapters/llmResolver.ts (new)
+- app/src/app.ts
+
+## Step 3.4 — Fallback strategy
+
+Goal:
+
+- Support deterministic fallback when LLM resolver fails or is low confidence.
+
+Target files:
+
+- app/src/interpreter/interpretTurn.ts
+
+---
+
+# Phase 4 — Rulebook Governance and Compatibility
+
+Status: IN PROGRESS
+
+## Step 4.1 — Rulebook versioning
+
+Goal:
+
+- Add version field and migration path for existing saved rulebooks.
+
+Status: COMPLETE
+
+Target files:
+
+- app/src/contracts/rulebook.ts
+- app/src/defaultRulebook.ts
+- app/src/db.ts
+
+## Step 4.2 — Policy pack structure
+
+Goal:
+
+- Organize rules into policy packs (creation, transfer, social) while retaining current behavior.
+
+Target files:
+
+- app/src/defaultRulebook.ts
+
+## Step 4.3 — Rulebook editor affordances
+
+Goal:
+
+- Surface policy grouping and version in the frontend editor.
+
+Target files:
+
+- frontend/src/App.tsx
+
+---
+
+# Phase 5 — Docker-First Test Harness
+
+Status: NOT STARTED
+
+## Step 5.1 — Backend integration tests
+
+Goal:
+
+- Cover deterministic scenarios:
+  - unauthorized createIfMissing denied
+  - authorized createIfMissing allowed
+  - transfer success and failure matrix
+  - unresolved intent clarification behavior
+
+Target files:
+
+- app/src/** tests (new)
+
+## Step 5.2 — Containerized test commands
+
+Goal:
+
+- Provide canonical Docker commands for app/frontend build and tests.
+
+Target files:
+
+- charactergarden/docker-compose.yml
+- project.md
+- thoughts.md
+
+## Step 5.3 — CI readiness checklist
+
+Goal:
+
+- Ensure all checks are containerized and reproducible.
+
+Deliverable:
+
+- One documented command sequence that reproduces local validation.
+
+---
+
+# Phase 6 — LLM Adapter Reintroduction
+
+Only after deterministic flow works.
+
+## Step 6.1 — LLM parser adapter
+
+Add optional LLM parser:
+
+```ts
+parseTextToActionsWithLLM(text: string, worldState: WorldState): Promise<Action[]>
+```
+
+It must output only valid `Action[]`.
+
+---
+
+## Step 6.2 — LLM narrative adapter
+
+Add:
+
+```ts
+generateNarrative(turn: Turn, worldState: WorldState): Promise<string>
+```
+
+The narrative adapter may describe results but must not alter them.
+
+---
+
+# Phase 7 — Frontend Debug UI
+
+## Step 7.1 — Show raw text input
+
+User can submit a turn.
+
+---
+
+## Step 7.2 — Show parsed actions
+
+Display action JSON.
+
+---
+
+## Step 7.3 — Show validation results
+
+Display success/failure reasons.
+
+---
+
+## Step 7.4 — Show world state
+
+Display current world state JSON.
+
+---
+
+# MVP Completion Criteria
+
+MVP is complete when this works:
+
+1. User enters: `take key`
+2. Parser returns a `take` action
+3. Truth engine validates it
+4. World state moves key to inventory
+5. User enters: `open door`
+6. Truth engine verifies key ownership
+7. Door becomes open
+8. All steps are visible in debug UI
+9. All turns are persisted
+
+---
+
+# Do Not Do Yet
+
+Do not implement:
+
+* autonomous agents
+* complex memory retrieval
+* embeddings
+* relationship simulation
+* long-term summaries
+* branching timelines
+
+Until the deterministic MVP is working.

-# CharacterGarden – AI-Oriented Design Spec (Copilot-Ready)
+# CharacterGarden MVP - Current Architecture (April 2026)
 
-## 0. Purpose
+## Core Principle
 
-This document defines **hard contracts and system boundaries** for CharacterGarden.
+The simulation engine is deterministic and authoritative.
+The LLM layer is an intent interpreter and resolver, not a source of truth.
 
-Goal: enable an AI coding assistant (e.g. Copilot) to implement the system step-by-step without ambiguity.
+## Live System Layers
 
-Core principle:
+User / LLM Input (Prose)
+        |
+[Intent Interpreter Layer]
+        |
+[Turn Manager]
+        |
+[Truth Engine + Scene Rulebook Validation]
+        |
+[World Mutation Engine]
+        |
+[Persistence Layer]
+        |
+[Frontend/API Response]
 
-> The application owns truth. The LLM only translates and narrates.
+## Non-Negotiable Rules
 
----
+1. Truth engine must never parse natural language.
+2. Only structured actions can mutate world state.
+3. Every mutation must pass validation before apply.
+4. Rulebook rules are data-driven and editable.
+5. Interpreter output is traceable and never auto-trusted when unresolved.
+6. Every turn remains replayable end-to-end.
 
-## 1. System Overview
+## Current Canonical Actions
 
-### Pipeline
+- inspect
+- move
+- open
+- take
+- introduce
+- describe
+- transfer
 
-```
+## Action Contracts (Current)
-Prose Input
-→ Intent Extraction
-→ Canonical Actions
-→ Truth Engine Validation
-→ State Changes + Events
-→ Memory Storage
-→ Narration Output
-```
 
----
+- Action shape is contract-based in app/src/contracts/action.ts
+- Validation contracts in app/src/contracts/validation.ts
+- Turn contracts in app/src/contracts/turn.ts
+- Interpreter contracts in app/src/contracts/intent.ts
 
-## 2. Core Contracts (STRICT)
+## Scene Rulebook (Data-Driven Validation)
 
-### 2.1 Entity
+Validation is now externalized into SceneRulebook definitions.
 
-```
+Key capabilities already implemented:
-Entity {
-  id: string
-  type: string
-  name: string
-  attributes: object
-}
-```
 
-### 2.2 Action (Canonical)
+- Actor authorization checks (actorIdIn, actorNameIn)
+- Conditional creation checks (actionMetadataEq)
+- Inventory ownership checks (itemInInventory)
+- Existing deterministic checks (entity type/exists, same location, attribute checks)
 
-```
+This supports:
-Action {
-  actor: string (entity id)
-  verb: string (enum)
-  target?: string (entity id)
-  params?: object
-}
-```
 
-Allowed verbs (MVP):
+- Restricting who can introduce characters
+- Restricting who can create missing items via take
+- Validating transfer only when actor owns item and recipient is valid
 
-```
+## Turn Execution (Current)
-move, open, close, take, drop, use, inspect, speak
-```
 
-### 2.3 Validation Result
+1. Interpret raw turn text using interpreter module.
+2. If unresolved:
+   - return clarification/rejection state
+   - persist trace turn with no applied actions
+3. If resolved:
+   - validate actions with truth engine + active rulebook
+   - apply successful actions
+   - persist turn, actions, validation results, and world state
 
-```
+## Interpreter + Turn Manager (New)
-ValidationResult {
-  accepted: Action[]
-  rejected: { action: Action, reason: string }[]
-  state_changes: StateChange[]
-}
-```
 
-### 2.4 State Change
+- Interpreter module: app/src/interpreter/interpretTurn.ts
+- Turn manager orchestrator: app/src/turns/turnManager.ts
+- processTurn delegates to turn manager: app/src/turns/processTurn.ts
 
-```
+Current interpreter statuses:
-StateChange {
-  entity_id: string
-  field: string
-  old_value: any
-  new_value: any
-}
-```
 
-### 2.5 Event
+- resolved
+- needs_clarification
+- rejected
 
-```
+## Current Domain Behaviors
-Event {
-  id: string
-  turn: number
-  action: Action
-  result: "success" | "fail"
-  timestamp: number
-}
-```
 
----
+- take can create missing items when createIfMissing is present and actor is authorized by rulebook
+- introduce can create missing characters when rulebook allows
+- transfer moves items between inventories when rulebook checks pass
 
-## 3. Truth Rules
+## Persistence (Current)
 
-1. Only the **Truth Engine** can modify world state
+SQLite tables already backing turns and world snapshots:
-2. LLM output is NEVER directly trusted
-3. Every state change must be traceable to an Event
-4. Invalid actions must return explicit failure reasons
 
----
+- turns
+- actions
+- validation_results
+- entities
+- world_states
+- rulebooks
 
-## 4. Memory Model
+## API Surface (Current)
 
-Memory is NOT a single blob.
+- GET /api/state
+- POST /api/turn
+- POST /api/reset
+- GET /api/rulebook
+- PUT /api/rulebook
+- GET /api/rulebooks
 
-### Types
+## Operational Rule: Validation in Docker
 
-#### 4.1 Turn
+Build and runtime checks should run in containers, not host Node.
 
-Raw input/output
+- Backend build: docker compose run --rm app npm run build
+- Frontend build: docker compose run --rm frontend npm run build
 
-#### 4.2 Event
+## Immediate Path Forward
 
-Accepted or rejected actions
+1. LLM adapter hardening
+- Tune prompt/schema validation for model drift.
+- Add configurable model + timeout policy per environment.
 
-#### 4.3 Fact
+2. Rulebook governance
+- Keep versioned rulebook migration path active as rule schema evolves.
+- Split rules into policy packs: creation, transfer, social.
 
-Current world state (derived, not duplicated)
+3. Testing depth
-
+- Expand Docker-executed integration tests for:
-#### 4.4 Belief
+-  createIfMissing authorization matrix
-
+-  transfer ownership/location checks
-```
+-  unresolved clarification flows
-Belief {
+-  multi-action turn behavior
-  entity_id: string
-  claim: string
-  confidence: number
-}
-```
-
-#### 4.5 Summary
-
-Compressed narrative context

-
-## 8. Docker Design
-
-### Services
-
-```
-services:
-  app
-  frontend
-  ollama (optional)
-```
-
-### Principles
-
-* No host dependencies beyond Docker

-* Use `.env` for config
-* No hidden setup scripts
-
----
-
-## 9. Folder Structure
-
-```
-charactergarden/
-  docker-compose.yml
-  .env
-  app/
-  frontend/
-  data/
-    sqlite/
-```
-
----
-
-## 10. MVP Scope
-
-STRICT LIMITS:
-
-* 1–2 rooms
-* ≤3 characters
-* ≤10 actions
-* no complex AI autonomy
-* no multi-agent loops yet
-
----
-
-## 11. Non-Goals (DO NOT BUILD YET)
-
-* microservices
-* distributed systems
-* plugin frameworks
-* advanced agent loops
-* cloud dependencies
-
----
-
-## 12. Development Workflow Rule
-
-A root-level file named `thoughts.md` must exist and be maintained throughout development.
-
-Purpose of `thoughts.md`:
-
-* record current implementation status
-* record the next planned steps
-* record blockers, assumptions, and unresolved questions
-* summarize architectural decisions already made
-* preserve continuity across editor sessions or context loss
-
-Rules for `thoughts.md`:
-
-* update it after each meaningful implementation step
-* keep entries concise and factual
-* do not use it for chain-of-thought dumping or vague brainstorming
-* use it as a project progress log and working memory
-* when resuming work, review `thoughts.md` first before making changes
-* when changing architecture, record what changed and why
-* when a task is incomplete, note exactly what remains
-
-Recommended structure:
-
-```md
-# thoughts.md
-
-## Current Status
-- what is implemented
-- what is partially implemented
-- what is broken or unverified
-
-## Current Architecture Decisions
-- key decisions and constraints
-
-## Next Steps
-- ordered checklist of immediate tasks
-
-## Open Questions
-- unresolved design or implementation questions
-
-## Session Notes
-- short dated notes describing recent progress
-```
-
-Copilot instruction:
-
-> Before starting work, read `thoughts.md`. After completing any meaningful change, update `thoughts.md` to reflect current status, next steps, and any unresolved issues.
-
-## 13. Development Order
-
-1. Define entities + actions
-2. Implement truth engine
-3. Add SQLite persistence
-4. Build API endpoints
-5. Add minimal UI
-6. Add LLM integration
-
----
-
-## 14. Key Rule
-
-> If the system works without an LLM, the architecture is correct.
-
----
-
-## 15. Expected Behavior
-
-* deterministic state
-* explainable failures
-* replayable sessions
-* inspectable memory
-
----
-
-## 16. Future Extensions (NOT NOW)
-
-* branching timelines
-* advanced belief systems
-* multi-agent arbitration
-* long-term memory compression
-
----

 # thoughts.md
 
-## Current Status
+## Documentation Sync
-- Scaffold complete: `charactergarden/` folder structure created per spec section 9
-- Core contracts defined in `app/src/types.ts`: Entity, Action, Verb, ValidationResult, StateChange, GameEvent, Turn, Belief, Fact, Affordance, Summary
-- `docker-compose.yml` created; ollama service gated behind `--profile llm` (not required for MVP)
-- `.env` / `.env.example` / `.gitignore` in place
-- Container-first runtime files added: app/frontend Dockerfiles and `.dockerignore`s
-- **Truth Engine implemented** in `app/src/truthEngine.ts` — pure function, no I/O, no LLM
-  - `validate(actions, worldState)` → ValidationResult
-  - `applyChanges(worldState, changes)` → new WorldState (immutable)
-  - All 8 verbs handled with explicit rejection reasons
-- `move` now supports a built-in offscene room convention via `createOffsceneRoom()`
-- `latentEntities.ts` can promote plausible personal items from belief to fact when the actor has carrying context
-- `db.ts` added with SQLite schema + persistence helpers for `entities`, `events`, `turns`, `beliefs`, and `summaries`
-- Minimal Fastify server + app pipeline added with seeded world state and fallback parser
-- Minimal Vite React inspector added for visual boot testing and state inspection
 
-## Current Architecture Decisions
+- Implementation plan refreshed in Implementation_plan.md to match current codebase state.
-- App: Node.js + Fastify + TypeScript
+- Next executable phase is Phase 1: Intent Interpreter Boundary Hardening.
-- Frontend: React + Vite + TypeScript
-- Database: better-sqlite3 (synchronous, no ORM)
-- Ollama is optional; system must work without it (per section 14)
-- `Event` type renamed `GameEvent` in code to avoid collision with the DOM `Event` global
-- Latent personal items are gated by facts-derived affordances, not accepted directly from beliefs
-- The offscene room is represented as a normal room entity with id `offscene`
-- App and frontend should be run and validated through Docker Compose rather than host-installed Node
 
-## Next Steps
+## Current Snapshot (April 2026)
-1. Implement App service / turn flow (`app/src/app.ts`) per section 6
-2. Validate Docker boot and iterate on any compile/runtime failures
-3. Expand fallback parser coverage and tighten truth-engine world rules
-4. Add LLM adapter implementation beyond fallback parsing
 
-## Open Questions
+### What is now working
-- Should room/location be an Entity attribute or a separate entity type?
-- What is the initial world state for the MVP (1–2 rooms, ≤3 characters)?
-- Should latent personal-item plausibility live only on actor attributes, or also look at worn item/container entities?
 
-## Session Notes
+- Rulebook-driven validation is active and editable through API/frontend.
-- 2026-04-23: Project started. Scaffold, type contracts, .gitignore, and .env.example created.
+- Character authorization rules are in place (actorIdIn / actorNameIn).
-- 2026-04-23: Truth Engine implemented. Pure validation with per-verb handlers and immutable applyChanges helper.
+- take supports createIfMissing, gated by rulebook permissions.
-- 2026-04-23: Added facts/affordances + latent entity resolver for improv-style personal items, plus offscene room support.
+- transfer action is live with ownership + recipient + location validation.
-- 2026-04-23: Added SQLite schema module. Host `npm install` is blocked by `better-sqlite3` on Windows Node 25, so runtime validation should happen inside Docker on an LTS Node image instead.
+- Turn processing now goes through a dedicated turn manager layer.
-- 2026-04-23: Added minimal backend/frontend boot slice so the project can be tested visually through Docker.
+- Intent interpreter contract exists with resolved / needs_clarification / rejected statuses.
+- Interpreter envelopes are persisted per turn and surfaced to the UI timeline.
+- LLM resolver now calls an HTTP model backend (Ollama-compatible) with hybrid deterministic fallback.
+- Rulebooks now include a version field with backward-compatible DB migration.
+- Turn log now returns populated actions and validation results per turn (previously always empty).
+- Active rulebook ID is now persisted on worldState and survives restarts.
+- `take` sets `has_<item_id>` generically on the actor (was hardcoded to key_1 only).
+
+### Structural refactoring completed (April 2026)
+
+- **Deleted `turns/processTurn.ts`** — was a 3-line shim over runTurnManager. app.ts now calls runTurnManager directly.
+- **Deleted `truthEngine.ts`** — was a thin wrapper over rulebookEngine.validateWithRulebook. turnManager.ts now calls validateWithRulebook directly.
+- **Extracted `world/seedWorld.ts`** — createSeedWorldState, mergeSeedWorldState, ensureSeedState moved out of app.ts. App factory is now clean.
+- **Fixed `db.listTurns()`** — now reads back actions and validation_results from their tables. Frontend turn log now has real data.
+- **Fixed `worldState.rulebookId` persistence** — upsertRulebook now updates worldState.rulebookId and persists a world snapshot so the active rulebook survives restarts.
+- **Generalized `has_<item_id>` in applyActions** — `take` now sets `has_<item_id>` on the actor for all taken items, not just `key_1`. The attributeRef rulebook check continues to work generically.
+
+### Confirmed via containerized validation
+
+- Backend build passes in Docker:
+  - docker compose run --rm app npm run build
+- Frontend build passes in Docker:
+  - docker compose run --rm frontend npm run build
+- Host Node build is intentionally not relied on.
+
+## Architecture Feedback
+
+### Good decisions worth keeping
+
+1. Rulebook externalization
+- Pulling edge-case logic out of hardcoded truth engine branches was the right move.
+- It now supports editable policy without code deployment.
+
+2. Explicit authorization checks in rules
+- Authorization for creation-style actions now belongs to policy, not parser guesswork.
+- This aligns with deterministic governance.
+
+3. Introducing transfer as first-class action
+- This avoids overloading take semantics and keeps intent/action boundaries cleaner.
+
+4. Turn manager seam
+- processTurn delegating to a turn manager creates a stable orchestration point for interpreter upgrades.
+
+### Risks / cleanup still needed
+
+1. Frontend contract drift risk
+- App.tsx has historically duplicated blocks during rapid edits.
+- Keep one canonical component and avoid append-style merges.
+
+2. Interpreter observability depth
+- Interpreter traces are persisted, but aggregate analytics/counters are still missing.
+
+3. Rulebook migration strategy
+- Existing DBs may hold older rulebooks missing new action rule sets.
+- Need explicit upgrade path/versioning.
+
+4. Parser is world-specific
+- parseTextToActions.ts hardcodes entity IDs (room_exit, door_1, key_1, groundskeeper).
+- The parser is used only inside the deterministic resolver adapter; keeping it isolated limits blast radius, but a future world-context-aware resolver would eliminate this entirely.
+
+5. Entity table vs world_state blob redundancy
+- `entities` table and `world_states.state_json` both store entity data. The entities table is the live read target; world_states is the history log. No query capability on history. Acceptable for MVP.
+
+## Path Forward (Next 3 Iterations)
+
+### Iteration 1: LLM adapter hardening
+
+- Harden prompt + response schema handling for model drift and malformed JSON.
+- Add environment-specific model/timeouts and failure policy guidance.
+- Add tests covering unavailable model backend and malformed payload fallback.
+
+### Iteration 2: Traceability + observability
+
+- Surface interpreter status in frontend turn log.
+- Add reason-code analytics counters for failed validations and unresolved intents.
+
+### Iteration 3: Rulebook lifecycle and test harness
+
+- Add policy packs (creation, transfer, social).
+- Add Docker-run integration tests for:
+  - unauthorized createIfMissing
+  - authorized createIfMissing
+  - transfer success/failure matrix
+  - clarification path for ambiguous/unrecognized input
+
+## Operating Guidance
+
+- Keep all build/test checks containerized.
+- Treat interpreter as replaceable adapter behind a stable contract.
+- Keep truth engine deterministic and side-effect free.
+- Keep mutation logic pure relative to validated actions only.
