[Unreleased]

Added — Sprint 3: Nausea Symptom System

• 3.1 Symptom manager autoload (scripts/game_systems/symptom_manager.gd): generic per-symptom intensities clamped to [0, 100], trigger_symptom / add_intensity / get_intensity / reset_all, and nausea_intensity_changed + generic symptom_intensity_changed signals. Registered as the SymptomManager autoload.
• 3.2 Screen tilt effect (scripts/symptoms/nausea_tilt.gd): camera Z-axis roll oscillating at ~0.3 Hz, amplitude scaled by nausea up to ~5°, smoothly following intensity. Attached to the player Camera3D.
• 3.3 Color desaturation shader (assets/shaders/desaturation.gdshader + scripts/symptoms/nausea_desaturation.gd + scenes/symptoms/nausea_overlay.tscn): full-screen ColorRect that blends the screen toward grayscale, reaching full desaturation at nausea ≥ 80, fading smoothly with intensity.
• 3.4 Treatment manager (scripts/game_systems/treatment_manager.gd): on IV iv_completed, ramps nausea from its current value to ~40 over 30 seconds, then holds. SymptomManager propagates changes to the tilt and desaturation effects. Wired IVInsertion.iv_completed → TreatmentManager.start_ramp.

Added — Sprint 2: Environment & Character

• 2.1 Hospital room scene (scenes/hospital/hospital_room.tscn): floor, ceiling, four walls (with collision), placeholder furniture (bed, chair, IV stand, bedside table), fluorescent lighting (directional + omni), and a start camera/player facing the chair. Set as run/main_scene.
• 2.2 First-person controller (scripts/character/player_controller.gd + scenes/hospital/player.tscn): CharacterBody3D with capsule collision, child Camera3D, WASD movement, captured mouse-look (pitch clamped), gravity, and an interaction RayCast3D. Added move_* / interact input actions to project.godot.
• 2.3 Sit-down interaction (scripts/character/chair_interaction.gd + scenes/hospital/chair_interaction.tscn): Area3D trigger with "Press E to sit/stand" prompt, smooth tween to a seat marker, movement lock while seated, and player_seated / player_stood signals.
• 2.4 IV insertion sequence (scripts/character/iv_insertion.gd + scenes/hospital/iv_insertion.tscn): IV arm placeholder with a tweened needle-approach + tape-press animation, emitting iv_completed. Wired ChairInteraction.player_seated → IVInsertion.begin_sequence in the room scene.

Added — Sprint 1: Project Scaffolding & Core Tech

• 1.1 Initialized Godot 4.x project: project.godot (name chemo-sim, version 0.1.0, Forward+ renderer with mobile fallback, 1920×1080 window).
• 1.2 Created directory structure per docs/ARCHITECTURE.md (scenes/, scripts/, assets/, export_templates/, build/), with .gitkeep placeholders so empty dirs are tracked.
• 1.3 Set up Gitea Actions CI/CD (.gitea/workflows/build.yml): builds on push/PR to main, exports Windows .exe + Linux .x86_64 via the barichello/godot-ci:4.3 container, uploads artifacts per run. Removed the GitHub Actions workflow in favor of Gitea-only CI.
• 1.4 Configured export presets (export_presets.cfg) for Windows Desktop and Linux (x86_64). Verified both export locally via godot --export-release (Windows .exe ~80 MB, Linux .x86_64 ~63 MB).
• Added placeholder icon.svg referenced by project.godot.

Fixed

• Corrected .gitignore: removed *.godot rule that would have ignored the required project.godot; added Godot 4 cache (.godot/), local toolchain (tools/), and build output ignores.
