megaproxy cd265b87c0 Phase 2 — Pawn, pathfinder, click-to-select / click-to-move
Pawn (scenes/pawn/{tscn,gd}, ~108 lines, gdscript-refactor agent):
- Node2D root (no physics — grid-snapped lerped motion); name + state labels
- _draw() paints body disc with hue derived from name.hash(), dark outline,
  yellow selection ring when selected
- Clock = EventBus.sim_tick: each tick advances _step_progress by 1/10;
  at 1.0 snaps tile to next waypoint, pops path. STEP_TICKS = 10 →
  1 tile / 0.5 s at 1×, scales with Sim speed for free (pause/Fast/Ultra)
- _process() lerps render position between current and next tile every
  render frame for smooth visual between sim ticks
- Public API: setup, walk_along_path, is_walking, set_selected,
  signals walk_started/walk_completed/arrived_at_destination

Pathfinder (scenes/world/pathfinder.gd, ~110 lines, gdscript-refactor agent):
- AStarGrid2D wrapper, 80² region, DIAGONAL_MODE_NEVER (Rimworld
  4-directional), Manhattan heuristic
- API: setup, set_cell_walkable (emits walkability_changed signal),
  is_walkable, find_path (excludes start tile, includes end), benchmark
- find_path returns empty Array[Vector2i] for OOB endpoints, solid
  destination, or disconnected areas

Selection (scenes/world/selection.gd, ~85 lines, Opus):
- Lives as a Node child of World; _unhandled_input handles mouse clicks
- Click-vs-drag discrimination: 8 px max drift + 300 ms max duration →
  drags belong to the camera, only true clicks select/command
- Click on pawn → select (yellow ring); click on walkable empty tile
  with a pawn selected → pathfinder.find_path + pawn.walk_along_path

World autoload (autoload/world.gd):
- Added pawn registry: register_pawn, unregister_pawn, pawn_at_tile, clear_pawns
- Untyped Array (Array[Pawn] hits Godot's class_name-not-yet-registered
  timing in autoload init; duck typing fine for current consumers)

World scene (scenes/world/{tscn,gd}):
- Pathfinder + Selection nodes added as children
- _ready() wires: pathfinder.setup(MAP_SIZE_TILES), walls → pathfinder
  (28 cells from 8×8 stone ring marked impassable), selection.bind(pathfinder),
  spawns 3 pawns (Bram/Cora/Edda) at (20/25/30, 40), runs spike benchmark
- main.gd bootstrap line bumped Phase 1 → Phase 2

i18n: 2 new keys (pawn.state.idle, pawn.state.walking)

Spike result — AStarGrid2D path-query timing at 80²:
- 36 paths (all 4-corner pairs × 3 iterations)
- min 6 μs, avg 9.1 μs, max 18 μs
- ~55× faster than the 'sub-millisecond' target in architecture.md

MCP runtime verification:
- play_scene → 3 pawns visible with distinct hashed-hue body colours
- execute_game_script: pathfinder.find_path((20,40)→(50,40)) returns
  38-step path (30 straight + 8 detour around the ring)
- bram.walk_along_path(path) → screenshot caught him mid-walk on south
  side of ring with state='walking' + selection ring visible
- arrival snapshot: state='idle'

Phase 2 gotcha (documented in implementation.md): class_name registration
happens at editor scan-time, not headless-load-time. First headless run
after authoring class_name files fails until reload_project rebuilds the
global class cache. Workflow: agent writes → MCP reload_project → headless
validate. Documented for future phases.

Delegation report this phase:
- gdscript-refactor (Sonnet) #1: Pawn class — scene, script, draw logic,
  movement loop, i18n keys. ~108 lines pawn.gd + 22 lines pawn.tscn.
  Headless-validated by the subagent (note: validated before world.gd's
  Pawn reference was added).
- gdscript-refactor (Sonnet) #2: Pathfinder class — AStarGrid2D wrapper,
  4-dir Manhattan, benchmark utility. ~110 lines pathfinder.gd. Headless-
  validated by the subagent.
- Opus: Selection module + World autoload registry + scene integration
  (world.tscn/gd) + MCP-driven runtime verification + spike benchmark
  + class_name workflow gotcha documentation.

## Locked from day one (per CLAUDE.md): no hardcoded display copy in scenes or
## scripts. If you have player-facing text, add a key here and call Strings.t(key).

## Locale switching is post-MVP; the indirection lands now so we don't have to
## retrofit the whole game later. When the table grows, move it to a .tres or
## external CSV import; the public API (`Strings.t(key)`) stays the same.
