 ## Current Status
 - 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, Summary
+- 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` created with defaults
-- Nothing is implemented yet — no logic, no database, no server
+- `.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
 - App: Node.js + Fastify + TypeScript
@@ -13,17 +22,24 @@
 - 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
-1. Implement Truth Engine (`app/src/truthEngine.ts`) — pure validation, no I/O
-2. Add SQLite schema + db module (`app/src/db.ts`) with the 5 tables from section 7
-3. Implement App service / turn flow (`app/src/index.ts`) per section 6
-4. Add Fastify route `POST /turn` that executes the full pipeline
-5. Stub LLM adapter (`app/src/llmAdapter.ts`) with a fallback parser
+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
 - 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
-- 2026-04-23: Project started. Scaffold and type contracts created. No logic yet.
+- 2026-04-23: Project started. Scaffold, type contracts, .gitignore, and .env.example created.
+- 2026-04-23: Truth Engine implemented. Pure validation with per-verb handlers and immutable applyChanges helper.
+- 2026-04-23: Added facts/affordances + latent entity resolver for improv-style personal items, plus offscene room support.
+- 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.
+- 2026-04-23: Added minimal backend/frontend boot slice so the project can be tested visually through Docker.
