scenes/maps/playground.tscn and crag.tscn are generated by the map scripts' Rebuild (inspector
button, or godot-mono --headless --path . tools/rebuild_maps.tscn) and loaded as saved by the game,
so hand edits stick. The crag route is saved as Marker3D nodes and crag_spike checks the saved
scene. Layout verified identical to the code-built one (tools/map_dump.tscn).

North of the playground, facing spawn: bouldering blocks, a ladder to an 8 m rest ledge,
a jug wall, a 0.4 m traverse ledge, an overhang with monkey bars and a lip bar onto a
16 m rest ledge, a chimney to the 26 m summit with throwable props. A 'Crag' teleport
marker at the base is the way down; teleports now land the floor on the marker's height.
Floor widened to 80 m. Regression: scenes/crag_spike.tscn (reach, free space, overlaps,
height, line of sight).

- PhysicsArms: per side 2.0 kg upper arm + 1.2 kg forearm RigidBody3D PD-chasing their
analytic 2-bone IK pose, solved per physics tick from the physical chest shoulders to the
physical hands; no joints (Box3D has no usable shoulder/wrist joint; AGENTS forbids joints
between tracked bodies). Budgets from a 60 kg mass stat: hand 90 < forearm 180 < upper
arm 360 < chest 2400 N. Owns calibration + reach budget (moved from BodyRig); 1 m snap,
non-finite reset, BodyMath.RotationError servo.
- Layer 5 = player arms (mask 1); props/table/floor masks include it; no self-collision.
- BodyRig: visuals only, arms drawn shoulder -> physical elbow -> wrist.
- ArmSpike: track gap 0, swing lag <= 6 cm, arm pushes prop with hand clear, forearm blocked
by bar without tunneling and quiet when pinned, teleport snap, NaN reset — PASS x3.
- CollapseSpike now runs the full body (49/49 x3); all six spikes PASS x3.
- HANDOFF/AGENTS: Stage 2 entry (item 10), layers, tuning table, Stage 2b next steps.
