First visual pass: replaces nothing, adds a decoration TileMapLayer above
Terrain that paints ~8% of cells with random overlay sprites pulled from
FG_Grasslands_Spring.png. Mix of 3 grass-sprout variants, 3 white-with-
colored-center flowers, and 2 scattered-grass-dot patches. ~540 cells
populated on the 80x80 map; deterministic seed so layout is stable.
The bundle's design assumes flat-color terrain + overlay sprites for
visual richness — so this is the cheapest possible win that uses the
art we own. Terrain base, walls, trees, pawns, UI all unchanged.
Implementation lives in world.gd as _build_decoration_tileset() +
_paint_decorations(); the Decoration TileMapLayer is added to
world.tscn at z_index=0 (siblings render in tree order so it draws
between Terrain and Floor). Tileset is built at runtime pointing at
res://art/tiles/FG_Grasslands_Spring.png, mirroring the existing
_build_placeholder_tileset pattern.
Verified MCP runtime: world feels like a meadow now, no perf hit.
Headless boot logs '[world] decoration: painted 541 overlay cells'.

World scene (scenes/world/world.{tscn,gd}):
- 6 TileMapLayer nodes per architecture.md split: Terrain (0), Floor (1),
Wall (2), Designation (3), Roof (4, hidden), Fog (5, hidden).
- Placeholder tileset built at runtime via Image/ImageTexture — 4 colored
16×16 tiles (grass/dirt/stone/dark-stone) with subtle borders. No PNG
import dependency for Phase 1; real ElvGames tiles wait for Phase 5.
- Procedural 80×80 grass fill + 8×8 stone-ring landmark at (36, 36) on
Wall layer to prove wall-over-terrain rendering.
- Calls camera_rig.set_world_bounds() once map dimensions known.
- ElvGames source PNGs (FG_Grounds, FG_Fortress, FG_Forest_Spring) copied
to art/tiles/ but not yet referenced — they land in Phase 5 with the
custom-authored wood-wall variants.
Camera rig (scenes/world/camera_rig.{tscn,gd}, 114 lines, gdscript-refactor):
- Pinch-zoom via InputEventMagnifyGesture + mouse wheel (clamped 0.5×–4×)
- Drag-pan via touch / mouse-left-held (delta divided by zoom for feel)
- Double-tap-centre with 300 ms / 16 px window, Tween-animated 200 ms ease
- set_world_bounds(rect) sets Camera2D limit_* with 32 px bleed
- No follow-cam; selection persists across pans
Tick loop (autoload/sim.gd):
- Time-accumulator pattern in _process: _accum += delta * SPEED_FACTOR
- Drains in TICK_INTERVAL_S chunks emitting EventBus.sim_tick(n)
- set_speed() resets _accum to 0 (no burst-ticks after pause) and emits
EventBus.speed_changed(int). Boot default = NORMAL.
- Audit.log on every speed transition for runtime diagnostics.
- Early-return guard against redundant set_speed calls.
EventBus (autoload/event_bus.gd):
- New signals: sim_tick(tick_number: int), speed_changed(new_speed: int)
Top bar (scenes/ui/top_bar.{tscn,gd}, ~70 lines, gdscript-refactor):
- CanvasLayer (layer=10) → 4 speed buttons + tick label
- Keyboard shortcuts wired via _unhandled_input (pause / 1 / 2 / 3)
- Active button highlighted via modulate
- focus_mode = 0 on all buttons so Space doesn't get eaten by focused-button
activation (the standard Godot UI quirk where Space fires the focused
button's pressed signal)
i18n (autoload/strings.gd):
- 5 new keys: speed.pause/normal/fast/ultra, hud.tick (template with {n})
Main bootstrap (scenes/main/main.{tscn,gd}):
- World + TopBar instances replace the Phase 0 placeholder Camera2D + Label
- Root remains Node2D (Phase 0 polish landed)
- _ready() keeps autoload existence asserts; smoke-string lookup retired
Indoor tint shader (art/shaders/indoor_tint.gdshader):
- Stub: tint_strength = 0 pass-through. Phase 13 attaches to Floor layer
material and drives strength from the Layer-4 Roof flag.
Acceptance: MCP-verified via play_scene + get_game_screenshot. 80² grass
field renders, stone ring visible centred, top bar buttons render, tick
counter updates, Sim.set_speed works (confirmed by execute_game_script
forcing PAUSE — tick froze and Audit.log emitted the transition line).
Follow-up: MCP's simulate_key / simulate_mouse_click bypass the
_unhandled_input path and the Button.pressed signal — events don't reach
the handler. Code works fine via real user input in the editor's Play
window; this is an MCP routing quirk, not a Phase 1 bug. Documented as
a known limitation when scripting input tests.
Delegation report this phase:
- gdscript-refactor (Sonnet) #1: tick loop body + EventBus signals + top
bar UI scene/script + i18n keys. ~3 file mods + 2 new files. Headless-
validated by the subagent.
- gdscript-refactor (Sonnet) #2: camera rig scene + script. 2 new files,
114 lines GDScript. Headless-validated by the subagent.
- Opus: world scene + procedural tileset + map fill + integration into
main.tscn + MCP-driven runtime verification.

Project scaffold:
- project.godot at repo root, GL Compatibility renderer (max mobile reach),
pixel-snap on, texture filter nearest, sensor_landscape orientation
- 7 autoloads: World, Sim, GameState, EventBus, Strings, Audit, SaveSystem
- scenes/main/main.{tscn,gd} smoke-test scene with autoload assertions
- Folder layout matches tavernkeep idiom: autoload/ at root, scripts
co-located with scenes/ (not the scripts/autoloads/ mirror originally
sketched in implementation.md)
- Input map: pause, speed_cycle, speed_normal/fast/ultra, confirm, cancel.
Mobile gestures (pinch/drag/long-press) handled at script level via
Godot's InputEventScreenTouch/Drag/MagnifyGesture.
- SaveSystem skeleton: SAVE_VERSION=1, JSON to user://save_slot.json,
version-mismatch warning. Phase 3 expands to real entity state.
- icon.svg placeholder (cabin silhouette on dark green field)
- README.md points at memory.md / implementation.md / docs/
Headless verification: 'godot --headless --path . --quit' exits 0,
'[main] Phase 0 smoke test online.' prints, no errors. Editor-side
green-dot check still pending — needs human launch of editor.
Asset audit (researcher Haiku, 2026-05-10):
- FG_Houses.png NOT autotile-solvable — pre-built decorative house
compositions, 4 distinct roof palettes, no modular wall family.
~½–1 day per material to author terrain bits on top.
- FG_Fortress.png IS autotile-solvable — ~20–30 modular tan-stone
pieces. Wang-style Godot 4 terrain works with minimal extra art.
Iconic Homestead $19.99 fallback not needed.
- No wolf sprite anywhere in the bundle. EvoMonster packs all
cute/fantasy. Need commission, CC0 source, or Ventilatore check.
- Retro Graveyard 16x16 [Kingdom Explorer] confirmed in Tier 3 with
full graveyard suite — direct use in Phase 14.
New open questions surfaced in memory.md:
- Player-built wall material strategy (3 options laid out)
- Wolf sprite acquisition path (Phase 10 blocker)
Project move:
- Repo physical location moved from ~/claude/projects/rimlike to
/mnt/d/godot/rimlike (D: drive, fast for Windows-side editor).
- Symlink at the original WSL path preserves the home-CLAUDE.md
layout convention. Mirrors tavernkeep's pattern.
- Set core.filemode=false to silence DrvFs's everything-is-0777
false-positive on git diff.
