CI / headless-tests (push) Canceled after 49s
Implement prototype: venue-driven simulation core, scenarios, tests, and playable entrance scene
- Godot 4.3 project scaffold with first-person guard, procedural world,
  interaction HUD, access inspection, radio forms, debug overlay, shift review
- Simulation core: ShiftCoordinator, VenueScenario, EventScheduler, NPCController/FSM,
  AccessVerifier, EscalationManager, RadioSystem, IncidentRecorder,
  ReputationEvaluator, CrowdSystem, EventBus
- Three authored scenarios (Hollywood Blvd building, The Joke Shop, TV studio)
- Custom headless test runner (25 tests) replacing editor-dependent GUT,
  plus GitHub Actions CI
- Documentation workflow live: README, PLAN (tech stack), TODO/DONE, MEMORY

# MEMORY
Session memory for durable decisions, state, and gotchas. Keep concise, remove obsolete entries.
## Decisions
- Engine: Godot 4.3 stable (official editor build, `~/.local/bin/godot`). The system's preinstalled `godot-runner` (4.7.2, Fedora) cannot load projects from arbitrary paths because it was compiled without path overrides; use the official editor binary instead.
- Language: GDScript. All cross-file references use explicit `preload()` constants (not `class_name` globals) so scripts compile in headless `--script` runs without the editor's class cache.
- Test framework deviation: the project uses a custom minimal headless test runner (`src/test/test_runner.gd`) instead of GUT, because GUT needs the editor plugin. CI runs it with `--headless`.
- Eventing: no autoload signal bus. `ShiftCoordinator` owns an `EventBus` instance (`src/core/event_bus.gd`) passed to subsystems; subsystems emit only when a bus is assigned. Autoloads at parse time are unreliable under `--script`.
- Static signals are not available in Godot 4.3 GDScript ("Expected func or var after static") — do not use them.
- GDScript lambdas capture local variables **by value**; mutating a captured local inside a lambda does not affect the outer variable. Use member functions for accumulators in tests.
- Prototype shift duration defaults to 300 s for testing; production targets 10-15 minutes per PLAN.md.
- RNG: NPC reactions and event scheduling are seedable for deterministic tests.
## Current State
- Core simulation, three scenarios, headless tests (25 passing), and a first-person prototype with interaction HUD, access inspection, radio (assist + emergency hold-to-confirm), debug overlay, and shift review are implemented and green.
- Run tests: `godot --headless --path . --script res://src/test/test_runner.gd`
- Boot check: `godot --headless --path . --quit-after 120`
- Screenshot tool: `godot --path . --script res://src/test/take_screenshot.gd` (writes to `user://screenshot.png`).
## Known Issues / Notes
- RefCounted reference cycle: `NPCController` holds an `FSM` that holds a back-reference to its owner, so test suites report "resources still in use at exit". Benign (process exit), but worth breaking later (e.g. `WeakRef` or explicit `dispose()`).
- Headless (dummy renderer) logs "Parameter m is null" from `mesh_get_surface_count`; it does not occur with a real GL driver and does not affect logic.
- NPC avatars all walk to the entrance and idle; per-intent waypoints are not implemented yet (see TODO).
- Wand screening (Joke Shop) is policy-only; the interaction is not yet in the prototype (see TODO).
## Open Questions
- Tone picker UI design and whether tones should be selectable per interaction.
- Whether the responder avatar should be playable/controllable or purely scripted.
- Localization target languages.
