User feedback after first visual inspection: 'walls looked really thick
and there was hardly any inside space'. Five targeted fixes:
1. Wall._draw rewrite — proper within-tile 3/4 perspective. Previously the
wall was a 16w×32h bottom-anchored rect that rose UP into the cell
above (which encroached on the cabin interior whenever the wall faced
south). New layout: 16×16 fitting strictly inside its own tile, with
a lit-top 5px band + shaded-front 11px band + mortar lines + outline.
Reads as 'a wall standing up' without overlapping adjacent cells.
Same shape for stone and wood materials (different palettes).
2. Demo cabin expanded from 5×4 to 8×6 — interior went from 6 cells
(closet) to 24 cells (actual room).
3. Grass-tile border darken: 0.15 → 0.04. Killed the graph-paper effect
that dominated at 3×+ zoom. Tile boundary still readable when looking
carefully; doesn't dominate the visual.
4. Removed Phase 1 _paint_sample_walls() seed. That 8×8 stone ring lived
only on the Wall TileMap layer (set to visible=false in the Phase 5
rendering pivot) — so it was an invisible path obstacle. Cleaner to
not seed it at all now that walls render at entity level.
5. CameraRig default target_zoom: 1.0 → 2.5. At 1× on a 1280-px viewport
the world feels sparse and pawns become 6-pixel dots. 2.5× shows ~30
tiles wide which is the 'comfortable inspection' level.
MCP-verified visually: the cabin now reads as a proper 8×6 stone room
with raised 3/4 walls and a real 24-cell interior. Subtle grass field.
The 'commit to 3/4 perspective' rendering decision is now actually
visible (was conceptual-only before).

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.
