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

+# TODO
+
+## Core Simulation — NPC Perception
+
+- [ ] Implement a perception pass so NPCs react to the guard's gestures and proximity.
+- [ ] Give NPCs local waypoints per intent (photo spots, queue, stage door, sidewalk exit) instead of all walking to the entrance.
+- [ ] Add returning-trespasser behavior: an NPC that was directed away may circle back later in the shift.
+
+## Escalation and Radio — Responder Dispatch
+
+- [ ] Spawn a dispatched security NPC / armed responder avatar that arrives at the venue after the call delay.
+- [ ] Give the responder command, restraint, evacuation, and arrest outcomes that resolve the incident.
+- [ ] Add a visible emergency-radio cooldown indicator in the HUD.
+
+## Scenario Content — Wand Screening (The Joke Shop)
+
+- [ ] Implement the handheld wand inspection interaction with alerts from keys, belts, phones, and weapons.
+- [ ] Enforce screening-before-entry flow and record false alarm / prohibited item decisions.
+- [ ] Add venue-specific dialogue lines for door staff.
+
+## Polish and Accessibility
+
+- [ ] Add dialogue tone picker (Professional / Friendly / Firm / Suspicious) before addressing an NPC.
+- [ ] Add interaction alternatives that do not require precise aiming (e.g. scan-and-select pinned list of nearby NPCs).
+- [ ] Add visual and audio feedback per escalation level (colors, tones, shake).
+- [ ] Add audio for crowd ambience, radio responses, and confirmation prompts.
+- [ ] Externalize dialogue and UI text for localization.
+
+## Future Systems (design-level backlog)
+
+- [ ] Body-camera replay timeline in the shift review.
+- [ ] Long (10-15 minute) shift lengths and phase-based lighting.
+- [ ] Venue selection screen; export presets for desktop targets.
+- [ ] IDE/editor-based GUT integration when a Godot editor workflow is introduced.
+- [ ] Reduce RefCounted reference cycles (NPCController <-> FSM) noted in `MEMORY.md`.
