gmp(M02): extract local player movement

Work-Package: M02-GMP-MOVEMENT-001
Agent: sindo-main-codex
Tests: local movement and player input regressions; asset-free scene; renderer dry-run; coordinate, streaming, documentation and coordination gates
Fidelity: preserves current sandbox speed, acceleration, sprint and camera-relative flight behavior; build-12340 parity remains unverified

+# M02-GMP-MOVEMENT-001 — Local movement state/controller
+
+<!-- OPENWC_CLAIM:M02-GMP-MOVEMENT-001:sindo-main-codex:2026-07-16 -->
+
+## Ownership
+
+- Target: M02
+- Program: GMP
+- Owner/Agent ID: sindo-main-codex
+- Branch: `work/sindo-main-codex/m02-local-movement`
+- Lease expires UTC: 2026-07-16
+- Integrator: M02 milestone integrator
+
+## Outcome
+
+Move local velocity, sandbox flight state, acceleration and directional speed
+calculation from `ThirdPersonWowController` into a scene-free,
+independently-testable local movement controller without changing current
+sandbox motion.
+
+## Non-goals
+
+- Extract terrain queries, camera rig, character presentation or animation.
+- Add jump/fall/swim, server prediction or reconciliation.
+- Change current movement speeds, acceleration, camera-relative flight or ground snap.
+- Gate debug movement by build profile; that remains a separate M02 package.
+- Mark M02 complete or edit its checklist/Evidence.
+
+## Paths
+
+- Exclusive: `src/gameplay/movement/`,
+  `src/tools/verify_local_player_movement.gd`,
+  `docs/modules/local-player-movement.md`, this claim
+- Shared/hotspots: `src/scenes/player/third_person_wow_controller.gd`,
+  `src/tools/verify_player_input.gd`, `docs/modules/player-input.md`,
+  `docs/modules/README.md`
+- Generated/ignored: local `.godot`, native DLL, generated ADT resources and renderer corpus
+
+## Contracts and data
+
+- Public API: stateful `LocalPlayerMovementController`
+- Inputs: immutable `MoveIntent`, local Godot movement basis and physics delta seconds
+- Outputs: local Godot displacement and read-only velocity/flight state
+- Schema/cache/coordinate contracts: unchanged
+- Consumer: current sandbox player scene; later gameplay composition root
+
+## Dependencies
+
+- Requires: merged input seam on master `14dead1`
+- Blocks: terrain query and camera/presentation extraction from the player hotspot
+- External state: none; unit tests use synthetic intents and bases
+
+## Verification
+
+- Commands: dedicated pure movement verifier, player-input regression, asset-free
+  scene smoke, coordinate/StreamingFocus gates, renderer dry-run and repository gates
+- Fixtures: identity/rotated/pitched bases, acceleration steps, sprint and flight transitions
+- Fidelity evidence: exact current 7.0/4.5/4.5 speeds, 28.0 acceleration,
+  6x sandbox sprint and camera-relative free flight are regression-locked only
+- Performance budget: one small state update per physics tick; no allocation, I/O or scene lookup
+
+## Documentation deliverables
+
+- Inline public API docs for movement state/configuration and update methods
+- Local movement module specification with data-flow, state and sequence diagrams
+- Updated player-input consumer diagram/status and module registry
+
+## Simplicity and naming
+
+- Important name: `LocalPlayerMovementController`
+- Simplest approach: one stateful RefCounted owning velocity and flight toggle
+- Rejected complexity: generic locomotion framework, ECS component hierarchy and event bus
+- Unavoidable complexity: movement basis remains an explicit local-space input
+  so the pure controller does not discover player/camera Nodes
+- Measured optimization evidence: not applicable
+
+## Status
+
+- State: active
+- Done: claim and isolated worktree from updated master
+- Next: implement controller, migrate scene consumer, test and document
+- Blocked by:
+
