 <!-- OPENWC_HANDOFF:READY:M02-GMP-INPUT-001:6bd2e84 -->
 ## Ownership
 - Target: M02
 - Program: GMP/FND
 - Owner/Agent ID: sindo-main-codex
 - Branch: `work/sindo-main-codex/m02-player-input`
 - Lease expires UTC: 2026-07-16
 - Integrator: M02 milestone integrator
 ## Outcome
 Replace direct keyboard polling in the runtime player with remappable Input Map
 actions and an immutable `PlayerInputSource → MoveIntent` boundary while
 preserving the current render-sandbox movement behavior.
 ## Non-goals
 - Extract local movement, terrain query, camera rig or character presenters.
 - Claim exact build-12340 movement/keybinding parity before original-client fixtures.
 - Change movement speeds, camera geometry, terrain sampling or renderer behavior.
 - Mark M02 complete or edit its checklist/Evidence.
 ## Paths
 - Exclusive: `src/domain/input/`, `src/gameplay/input/`,
  `src/tests/scenes/player_input_regression.tscn`,
  `src/tools/verify_player_input.gd`, `docs/modules/player-input.md`, this claim
 - Shared/hotspots: `project.godot`,
  `src/scenes/player/third_person_wow_controller.gd`, `docs/modules/README.md`
 - Generated/ignored: Godot import metadata, `.uid` files and local renderer corpus
 ## Contracts and data
 - Public API: immutable `MoveIntent`; `PlayerInputSource.sample_move_intent`
 - Configuration: additive `openwc_player_*` Input Map actions
 - Persistence/schema/cache: unchanged
 - Consumers: current sandbox player controller; later local movement controller
 ## Dependencies
 - Requires: merged M01 coordinate/streaming-focus contracts on master `62eece9`
 - Blocks: later M02 movement-controller extraction
 - External state: none; tests use synthetic Input Map events
 ## Verification
 - Commands: dedicated player-input verifier, headless project load, coordinate
  boundary gate, coordination/documentation gates and diff hygiene
 - Fixtures: synthetic action strengths and configured default bindings
 - Fidelity evidence: current W/S/A/D, Shift, E/Q and Space sandbox behavior remains
  mapped through actions; exact 3.3.5a semantics remain unverified
 - Performance budget: one immutable intent allocation per physics tick; no I/O
 ## Documentation deliverables
 - Inline API documentation for `MoveIntent`, `PlayerInputActions` and
  `PlayerInputSource`
 - Player-input module specification with inputs/outputs, data-flow and sequence diagrams
 - Module registry/source map and honest capability status
 ## Simplicity and naming
 - Important names: `MoveIntent`, `PlayerInputSource`, `PlayerInputActions`
 - Simplest approach: immutable value, one input adapter and one controller consumer
 - Rejected complexity: input provider hierarchy, event bus and generic command framework
 - Unavoidable complexity: none
 - Measured optimization evidence: not applicable
 ## Status
 - State: ready-for-review
 - Done: twelve remappable actions, immutable `MoveIntent`, stateless
  `PlayerInputSource`, controller migration, asset-free regression scene,
  dedicated verifier and module specification
 - Next: M02 integrator reviews and merges before local movement extraction
 - Blocked by:
 ## Handoff
 - Commit: `6bd2e84`
 - Branch: `work/sindo-main-codex/m02-player-input`
 - Outcome: the runtime player no longer polls physical keyboard keys. Movement
  action strengths cross an immutable `MoveIntent` seam; camera and immediate
  sandbox-flight events use the same remappable action catalog.
 - Public contract: additive `MoveIntent`, `PlayerInputActions` and
  `PlayerInputSource`; no schema, cache, coordinate or renderer contract change.
 - Verification: `PLAYER_INPUT PASS actions=12 intent_cases=6 controller=1
  regression_scene=1`; asset-free scene smoke exited `0`; coordinate boundary
  (`88` files) and StreamingFocus gates passed; unified renderer dry-run passed
  all eight pre-capture gates and produced seven dry-run checkpoint results;
  coordination/documentation/diff gates passed.
 - Fidelity: W/S/A/D, Shift, E/Q, Space, right mouse, wheel and Escape remain the
  default sandbox bindings. Regression drives forward movement, camera zoom and
  immediate flight toggle through the real controller. This does not establish
  exact build-12340 default bindings, turn/strafe policy or gameplay movement parity.
 - Local verification inputs: the isolated worktree reused the existing ignored
  native DLL and generated ADT resource scripts. Proprietary extracted data and
  the character GLB were absent, so the renderer dry-run logged the expected
  missing-corpus diagnostics while all contract steps returned success.
 - Rebuild/migration: none. Action names are additive; persisted user-binding
  migration does not exist yet and is documented as a gap.
 - Remaining risks: production profile gating for sprint/free flight, exact
  3.3.5a bindings, local movement/terrain/camera/presentation extraction and
  broader movement/camera state tests remain M02 work.
 - Documentation: inline API comments plus `docs/modules/player-input.md` with
  inputs/outputs, data-flow and sequence diagrams, ownership, recovery,
  capability status, known gaps and source map.

 # M02-GMP-MOVEMENT-001 — Local movement state/controller
 <!-- OPENWC_CLAIM:M02-GMP-MOVEMENT-001:sindo-main-codex:2026-07-16 -->
 <!-- OPENWC_HANDOFF:READY:M02-GMP-MOVEMENT-001:435e1c9 -->
 ## 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: ready-for-review
 - Done: scene-free movement state/controller, player scene migration, twelve
  numeric cases, two flight transitions, integrated regression and module documentation
 - Next: M02 integrator reviews and merges before TerrainQuery extraction
 - Blocked by:
 ## Handoff
 - Commit: `435e1c9`
 - Branch: `work/sindo-main-codex/m02-local-movement`
 - Outcome: `ThirdPersonWowController` no longer owns velocity, flight state,
  acceleration or directional speed calculation. It selects an explicit
  Godot-world basis, applies returned displacement, and retains terrain and
  presentation adapters for later M02 packages.
 - Public contract: additive `LocalPlayerMovementController` with read-only
  Godot-world velocity/flight state, `toggle_sandbox_flight` and `advance`.
  Input, coordinate, cache and renderer contracts remain unchanged.
 - Verification: `LOCAL_PLAYER_MOVEMENT PASS cases=12 state_transitions=2
  scene_boundary=1`; `PLAYER_INPUT PASS actions=12 intent_cases=6 controller=1
  regression_scene=1`; asset-free scene smoke exited `0`; coordinate boundary
  and StreamingFocus passed; renderer dry-run passed all eight pre-capture gates
  and seven checkpoint plans; coordination/documentation/diff gates passed.
 - Fidelity: exact existing defaults are regression-locked—forward `7.0`,
  backward/strafe `4.5`, acceleration `28.0`, sandbox sprint `6x`, vertical
  flight `7.0`, velocity reset on toggle and camera-relative pitched flight.
  This preserves the sandbox baseline but is not original-client evidence.
 - Local verification inputs: the isolated worktree reused the existing ignored
  native DLL and generated ADT resource scripts. Proprietary extracted data and
  character GLB were absent, so renderer dry-run logged expected missing-corpus
  diagnostics while every contract step returned success.
 - Rebuild/migration: none; transient movement state is not persisted.
 - Remaining risks: exported speed changes after `_ready` do not reconfigure the
  controller; exact build-12340 movement semantics, terrain/collision state,
  jump/fall/swim, server prediction and debug profile gating remain open.
 - Documentation: inline public API plus `docs/modules/local-player-movement.md`
  with inputs/outputs, data-flow, state and sequence diagrams, ownership,
  recovery, capability status, risks and source map; player-input consumer
  diagrams/status were updated.

 # M02-GMP-TERRAIN-QUERY-001 — Player terrain query boundary
 <!-- OPENWC_CLAIM:M02-GMP-TERRAIN-QUERY-001:sindo-main-codex:2026-07-16 -->
 <!-- OPENWC_HANDOFF:READY:M02-GMP-TERRAIN-QUERY-001:a45d521 -->
 ## Ownership
 - Target: M02
 - Program: GMP/RND
 - Owner/Agent ID: sindo-main-codex
 - Branch: `work/sindo-main-codex/m02-terrain-query`
 - Lease expires UTC: 2026-07-16
 - Integrator: M02 milestone integrator
 ## Outcome
 Introduce a typed `TerrainQuery` boundary and move ADT loading, caching, chunk
 selection and height interpolation out of `ThirdPersonWowController` without
 changing current spawn/ground-snap behavior.
 ## Non-goals
 - Change ADT topology, coordinate formulas, terrain mesh or renderer caches.
 - Add physics collision, slopes, water, jump/fall/swim or server movement.
 - Reuse the streaming renderer cache before its public terrain-query contract exists.
 - Extract camera or character presentation.
 - Mark M02 complete or edit its checklist/Evidence.
 ## Paths
 - Exclusive: `src/gameplay/terrain/`, `src/tools/verify_terrain_query.gd`,
  `docs/modules/terrain-query.md`, this claim

  `docs/modules/local-player-movement.md`,
  `docs/modules/README.md`
 - Generated/ignored: local `.godot`, native DLL, generated ADT resources and renderer corpus
 ## Contracts and data
 - Public API: `TerrainQuery.sample_ground_height(GodotWorldPosition)` returning
  immutable `TerrainGroundSample`
 - Production adapter: `AdtTerrainQuery` with owned per-tile parse cache
 - Test/data-source seam: optional ADT tile loader callable at construction
 - Coordinate contract version, ADT format, renderer cache and persistence: unchanged
 - Consumers: current player scene; future movement/collision policies
 ## Dependencies
 - Requires: merged movement controller on master `5206c42`
 - Blocks: camera/presentation extraction from the player hotspot
 - External state: production uses existing native `ADTLoader`; synthetic tests need no proprietary data
 ## Verification
 - Commands: synthetic height/cache/failure verifier, player input/movement
  regressions, asset-free scene, coordinate/StreamingFocus gates, renderer dry-run
  and repository gates
 - Fixtures: synthetic 145-height chunk payload and injected flat terrain query
 - Fidelity evidence: preserves existing outer-grid bilinear interpolation,
  spawn ground offset and per-tick snap formula only
 - Performance budget: one cached tile lookup and local interpolation per ground query;
  no new I/O after first tile load
 ## Documentation deliverables
 - Inline public API docs for query, sample and ADT adapter
 - Terrain-query module spec with inputs/outputs, data-flow, cache lifecycle and sequence diagrams
 - Updated movement/coordinate consumer boundaries, source maps and module registry
 ## Simplicity and naming
 - Important names: `TerrainQuery`, `TerrainGroundSample`, `AdtTerrainQuery`
 - Simplest approach: one narrow query contract, one typed result and one existing-format adapter
 - Rejected complexity: general collision framework, terrain service locator and renderer-cache coupling
 - Unavoidable complexity: ADT 145-height layout and chunk lookup stay isolated in adapter
 - Measured optimization evidence: existing per-tile cache retained; no new optimization
 ## Status
 - State: ready-for-review
 - Done: typed query/sample contract, cached ADT adapter, player migration,
  synthetic interpolation/cache/failure tests, injected scene regression and documentation
 - Next: M02 integrator reviews and merges before camera-rig extraction
 - Blocked by:
 ## Handoff
 - Commit: `a45d521`
 - Branch: `work/sindo-main-codex/m02-terrain-query`
 - Outcome: `ThirdPersonWowController` no longer loads ADTs, caches tile
  dictionaries, selects chunks or interpolates height grids. It consumes a
  replaceable typed `TerrainQuery` and retains only existing offset/snap policy.
 - Public contracts: additive immutable `TerrainGroundSample`, replaceable
  `TerrainQuery`, cached `AdtTerrainQuery` and player `set_terrain_query`.
  Coordinate contract version, ADT/native format and renderer caches are unchanged.
 - Verification: `TERRAIN_QUERY PASS contract=4 interpolation=1 cache=1
  failures=2 player_injection=1`; player-input and local-movement regressions
  passed; asset-free scene exited `0`; coordinate boundary passed with five
  required consumers and StreamingFocus passed; renderer dry-run passed eight
  pre-capture gates and seven checkpoint plans; coordination/documentation/diff gates passed.
 - Fidelity: synthetic fractional-grid fixture locks the inherited 145-height
  outer-grid bilinear result within `0.002` Godot units; injected scene locks
  spawn offset `0.05` and physics snap. This is sandbox-regression evidence,
  not build-12340 triangle/hole/collision parity.
 - Local verification inputs: isolated worktree reused the existing ignored
  native DLL and generated ADT resource scripts. Proprietary extracted data and
  character GLB were absent, so renderer dry-run logged expected missing-corpus
  diagnostics while all contract steps returned success.
 - Rebuild/migration: none; caches are transient and existing formats remain unchanged.
 - Remaining risks: first ADT parse remains synchronous as before; unavailable
  tiles cache until query replacement; player still owns snap policy; exact
  ADT triangle choice, holes, slopes, liquids and collision remain open.
 - Documentation: inline public APIs plus `docs/modules/terrain-query.md` with
  inputs/outputs, data-flow, cache state and cross-boundary sequence diagrams,
  ownership, failure/recovery, capability status and source map. Coordinate and
  movement consumer specifications were updated.

 # Local Player Movement
 ## Metadata
 | Field | Value |
 |---|---|
 | Status | Implemented |
 | Target/work package | M02 / M02-GMP-MOVEMENT-001 |
 | Owners | Gameplay local movement state; scene composition owns the instance |
 | Last verified | `a45d521`, 2026-07-14 |
 | Profiles/capabilities | Current render sandbox; production/debug profile gate pending |
 ## Purpose
 Own current local velocity, acceleration and sandbox flight state independently
 of the player scene. Convert an immutable `MoveIntent` plus an explicit
 Godot-world movement basis into deterministic per-tick displacement without
 querying terrain, cameras, input devices or visual assets.
 ## Non-goals
 - Apply world transforms or own a `CharacterBody3D`.
 - Query terrain height, collision, water or slopes.
 - Implement jump, fall, swim, server prediction or reconciliation.
 - Select the player basis versus camera-pivot basis; the scene adapter owns that decision.
 - Claim build-12340 movement fidelity from sandbox regression alone.
 ## Context and boundaries

 Allowed dependencies:
 - `MoveIntent` from the gameplay input boundary.
 - Godot value types `Basis` and `Vector3` for renderer world-space direction math.
 - Main-thread scene adapter for basis selection and displacement application.
 Forbidden dependencies:
 - `Node`, `Resource`, `Input`, `Camera3D`, `ADTLoader` or scene lookup.
 - World-coordinate conversion or manual ADT/tile formulas.
 - Character assets, animation players, materials, packets or server state.
 ## Public API
 | Symbol | Kind | Purpose | Thread/lifetime | Errors |
 |---|---|---|---|---|
 | `LocalPlayerMovementController.new(...)` | Constructor | Sets explicit speeds, acceleration and sandbox sprint multiplier | Created by composition root; retained for player scene lifetime | Caller owns configuration validation |
 | `godot_world_velocity_units_per_second` | Read-only state | Current Godot-world velocity after the last update | Stable until next mutation on owning thread | None |
 | `is_flight_enabled` | Read-only state | Current sandbox free-flight mode | Stable until toggle | None |
 | `toggle_sandbox_flight()` | Command | Toggles flight and clears velocity | Owning physics/input thread | Returns new flight state |
 | `advance(move_intent, godot_world_movement_basis, delta_seconds)` | Stateful update | Accelerates toward requested velocity and returns displacement for the tick | Owning physics thread; one call per tick | Negative delta is treated as zero |
 Constructor units:
 | Parameter | Unit/meaning |
 |---|---|
 | `run_speed_units_per_second` | Forward Godot units per second |
 | `backward_speed_units_per_second` | Backward Godot units per second |
 | `strafe_speed_units_per_second` | Lateral Godot units per second |
 | `flight_vertical_speed_units_per_second` | Sandbox vertical Godot units per second |
 | `acceleration_units_per_second_squared` | Velocity change per second |
 | `sandbox_sprint_multiplier` | Dimensionless debug multiplier |
 ## Inputs and outputs
 | Direction | Contract/data | Producer | Consumer | Ownership | Thread/lifetime |
 |---|---|---|---|---|---|
 | Input | `MoveIntent` | `PlayerInputSource` | Movement controller | Immutable caller-held value | One physics tick |
 | Input | Godot-world `Basis` | Player scene adapter | Movement controller | Value copy | One physics tick |
 | Input | Delta seconds | Godot physics loop | Movement controller | Scalar value | One physics tick |
 | Input | Flight toggle command | Remappable sandbox action via scene adapter | Movement controller | Synchronous command | Input event dispatch |
 | Output | Displacement `Vector3` | Movement controller | Player scene adapter | Value copy | Applied in same tick |
 | Output | Velocity `Vector3` | Movement controller | Facing/animation adapter | Read-only value copy | Until next update |
 | Output | Flight state | Movement controller | Basis/terrain scene adapter | Read-only boolean | Until next toggle |
 Side effects:
 - Mutates only controller-owned velocity and flight state.
 - Does not mutate scene tree, transforms, resources, filesystem, network or cache.
 - The scene adapter remains responsible for transform mutation and ground snap.

 ## Ownership, threading and resources
 - The player scene creates and exclusively owns one movement controller.
 - Velocity and flight state have the same lifetime as that controller.
 - All mutations currently occur on the main input/physics thread.
 - Read-only value returns are copies; consumers cannot mutate owned state.
 - No Nodes, Resources, RIDs, files, jobs or worker threads are created.
 - The supplied `Basis` is a Godot-world direction basis, not a typed world-position contract or coordinate conversion.
 ## Errors, cancellation and recovery
 | Failure | Detection | Behavior | Diagnostic | Recovery |
 |---|---|---|---|---|
 | Negative physics delta | `advance` guard | Returns zero displacement; velocity unchanged | Unit regression | Resume with valid non-negative delta |
 | Missing scene basis owner | Scene composition defect | Controller cannot be called correctly | Scene/parser error or boundary test | Restore explicit scene dependency |
 | Flight toggle during motion | Command path | Velocity clears before next step | State-transition regression | Continue from zero velocity |
 | Missing terrain data | `TerrainGroundSample.is_available == false` | Scene skips existing ground snap | Stable terrain failure code | Replace/recover query backend |
 There is no asynchronous cancellation, retry or rollback. Recreating the
 controller resets velocity and flight state deterministically.
 ## Configuration and capabilities
 | Setting/capability | Default | Profile | Runtime mutable | Effect |

 | Forward speed | `7.0` units/s | Current sandbox | Fixed for controller lifetime | Target forward velocity |
 | Backward speed | `4.5` units/s | Current sandbox | Fixed for controller lifetime | Target backward velocity |
 | Strafe speed | `4.5` units/s | Current sandbox | Fixed for controller lifetime | Target lateral velocity |
 | Acceleration | `28.0` units/s² | Current sandbox | Fixed for controller lifetime | Acceleration and deceleration |
 | Flight vertical speed | `7.0` units/s | Sandbox debug | Fixed for controller lifetime | Vertical free-flight target |
 | Sprint multiplier | `6.0` | Sandbox debug | Fixed for controller lifetime | Multiplies planar and vertical targets |
 | Camera-relative basis | Selected only while flight is enabled | Sandbox debug | Per tick | Preserves existing pitched flight direction |
 ## Persistence, cache and migration
 Movement state is transient and not serialized. No schema, cache, migration or
 saved settings change is introduced. Future reconnect/replay state requires a
 separate versioned movement snapshot contract.
 ## Diagnostics and observability
 - Logs: verifier emits `LOCAL_PLAYER_MOVEMENT PASS` or named invariant failures.
 - Metrics: none yet; update is constant-time vector math.
 - Debug views: current character facing and animation remain observable scene outputs.
 - Correlation IDs: not applicable to synchronous local sandbox state.
 ## Verification
 - Unit/contract: `src/tools/verify_local_player_movement.gd` covers forward,
  backward, strafe, rotated basis, acceleration, deceleration, sprint, flight,
  pitched camera basis, state reset and invalid delta.
 - Boundary: verifier rejects Node/Input/Camera/ADT dependencies and movement
  integration/state remaining in the player scene.
 - Scene integration: `verify_player_input.gd` drives the asset-free player
  regression scene through forward motion and immediate flight toggle.
 - Fidelity evidence: default values and formulas are regression-locked against
  the pre-extraction sandbox. No original-client comparison is claimed.
 - Performance budget: constant-time vector math, no per-tick I/O or scene lookup;
  `MoveIntent` allocation remains owned by the input package.
 ## Extension points
 - Terrain/collision policy can consume displacement without changing input or velocity ownership.
 - A future server-aware predictor may replace this controller behind the scene composition boundary.
 - A typed movement snapshot may expose deterministic replay state when M08/M09 require it.
 - Sandbox debug capability gating can reject sprint/flight before commands reach this controller.
 ## Capability status
 | Capability | Status | Evidence | Gap/next step |
 |---|---|---|---|
 | Scene-free local velocity state | Implemented | Pure controller and source boundary regression | Integrate target checklist after review |
 | Existing planar acceleration/speeds | Implemented | Exact numeric unit cases and real scene regression | Compare with build 12340 before fidelity claim |
 | Existing camera-relative free flight | Implemented | Pitched-basis and toggle/reset cases | Restrict to sandbox profile |
 | Terrain height query | Implemented | Typed `TerrainQuery` and injected player regression | Ground-snap policy remains scene-owned |
 | Terrain collision movement policy | Planned | Height-only query does not model collision | Add slopes/holes/collision later |
 | Jump/fall/swim | Planned | M02/M09 roadmap | Requires terrain/liquid and server contracts |
 | Prediction/reconciliation | Planned | M08/M09 roadmap | Requires movement snapshot/network contract |
 ## Known gaps and risks
 - Numeric defaults preserve the existing sandbox but are not original-client evidence.
 - Configuration is captured at scene `_ready`; runtime mutation of exported speed
  properties does not reconfigure an existing controller.
 - Ground snap remains in the player scene, but its ADT data access is now behind
  a replaceable `TerrainQuery`.
 - Sprint and free flight still lack a typed sandbox capability gate.
 - The module uses Godot math value types; a future engine-independent gameplay
  predictor may require scalar/domain movement contracts.

 # Player Input
 ## Metadata
 | Field | Value |
 |---|---|
 | Status | Partial |
 | Target/work package | M02 / M02-GMP-INPUT-001, M02-GMP-MOVEMENT-001 consumer update |
 | Owners | Gameplay input boundary; `sindo-main-codex` for current package |
 | Last verified | `435e1c9`, 2026-07-14 |
 | Profiles/capabilities | Current render-sandbox defaults; `Blizzlike335` binding semantics not yet verified |
 ## Purpose
 Convert remappable Godot Input Map actions into an immutable, scene-free
 `MoveIntent` that can be consumed by the current player controller and a later
 independently testable local movement controller.
 ## Non-goals
 - Define authoritative server movement, prediction or reconciliation.
 - Own character transform, terrain queries, camera state or animation state.
 - Claim that the current W/S/A/D sandbox mapping exactly matches build 12340.
 - Make sprint or free flight available to the production compatibility profile;
  their profile gate remains a later M02 package.
 ## Context and boundaries
 ```mermaid
 flowchart LR
    Devices[Keyboard and mouse] --> InputMap[Godot Input Map]
    InputMap --> Source[PlayerInputSource]
    Source --> Intent[MoveIntent]
    Intent --> Movement[LocalPlayerMovementController]
    Movement --> Controller[ThirdPersonWowController adapter]
    Controller --> Camera[Current camera adapter]
 ```
 Allowed dependencies:
 - `PlayerInputSource` may read Godot's process-wide `Input` adapter.
 - The scene controller may consume `MoveIntent` and camera-specific action names.
 - `MoveIntent` may contain scalar axes and request flags only.
 Forbidden dependencies:
 - `MoveIntent` must not read `Input`, inherit `Node`/`Resource`, or contain world coordinates.
 - The input source must not mutate player transforms, camera nodes or animation state.
 - Renderer, terrain parsers and network codecs must not read Input Map actions.
 ## Public API
 | Symbol | Kind | Purpose | Thread/lifetime | Errors |
 |---|---|---|---|---|
 | `MoveIntent` | Immutable value | Carries normalized forward, strafe and vertical axes plus the sandbox sprint request | Created and consumed on the main physics tick; caller retains reference | Constructor clamps axes; no I/O failure |
 | `MoveIntent.has_translation()` | Query | Reports whether any translation axis is non-zero | Any thread while value remains immutable | None |
 | `PlayerInputActions` | Constants | Provides stable action names shared by configuration and adapters | Process lifetime | Missing project actions are detected by verification |
 | `PlayerInputSource.sample_move_intent()` | Adapter method | Samples configured actions for one physics tick | Main thread; returned intent is independent of adapter lifetime | Missing actions resolve to zero strength and are a configuration defect |
 | `PlayerInputSource.compose_move_intent(...)` | Pure factory | Clamps strengths, cancels opposites and normalizes diagonal planar input | Any thread with scalar inputs | None |
 ## Inputs and outputs
 | Direction | Contract/data | Producer | Consumer | Ownership | Thread/lifetime |
 |---|---|---|---|---|---|
 | Input | Movement action strengths | Godot `InputMap`/`Input` | `PlayerInputSource` | Engine-owned snapshot | Sampled on main physics tick |
 | Input | Mouse action events | Godot `_unhandled_input` dispatch | Current scene controller | Engine-owned event | Current input dispatch only |
 | Output | `MoveIntent` | `PlayerInputSource` | `LocalPlayerMovementController` through scene composition | Immutable caller-held value | One physics tick |
 | Output | Camera action names | `PlayerInputActions` | Current scene controller | Static constants | Process lifetime |
 Side effects:
 - `PlayerInputSource` has no side effects beyond reading current engine input.
 - The existing controller still mutates player/camera transforms and mouse mode;
  those responsibilities are intentionally not moved by this package.
 - No filesystem, cache, network, database or renderer-resource mutation occurs.
 ## Data flow
 ```mermaid
 flowchart LR
    Project[project.godot action defaults] --> Map[InputMap]
    Remap[User or editor remapping] --> Map
    Map -->|movement strengths| Source[PlayerInputSource]
    Source -->|clamp cancel normalize| Intent[MoveIntent]
    Intent --> Consumer[LocalPlayerMovementController]
    Consumer --> Adapter[ThirdPersonWowController]
 ```
 ## Lifecycle/state
 The adapter is stateless. The scene composition root creates one
 `PlayerInputSource` and `LocalPlayerMovementController` in `_ready`; each physics
 tick produces a new immutable intent. Flight enabled/disabled state is owned by
 the movement controller and is not hidden in the input adapter.
 ## Main sequence
 ```mermaid
 sequenceDiagram
    participant Engine as Godot Input
    participant Source as PlayerInputSource
    participant Intent as MoveIntent
    participant Move as LocalPlayerMovementController
    participant Player as ThirdPersonWowController adapter
    Engine->>Source: movement action strengths
    Source->>Intent: compose normalized axes and requests
    Source-->>Player: sample_move_intent()
    Player->>Move: advance(intent, selected basis, delta)
    Move-->>Player: displacement and velocity state
 ```
 ## Ownership, threading and resources
 - The controller owns the input-source reference for its scene lifetime.
 - Each `MoveIntent` is immutable and retained only by its consumer.
 - Sampling and controller mutation occur on the main physics thread.
 - The module creates no Nodes, Resources, RIDs, workers or background jobs.
 - Input Map definitions are project configuration; runtime remapping remains
  engine-owned and does not mutate the domain value.
 ## Errors, cancellation and recovery
 | Failure | Detection | Behavior | Diagnostic | Recovery |
 |---|---|---|---|---|
 | Required action missing | Headless contract verifier | Godot returns zero input for that action | `PLAYER_INPUT` failure naming action | Restore action or user mapping |
 | Conflicting opposite actions | Pure composition | Strengths cancel deterministically | Covered by contract test | Release/remap one action |
 | Strength outside range | Pure composition | Value clamps to `[0, 1]` before axis calculation | Covered by contract test | Input adapter may be corrected independently |
 | Controller disabled/unloaded | Scene lifecycle | Sampling stops with physics processing | Existing scene lifecycle | Re-enable or recreate scene |
 There is no asynchronous operation to cancel and no persisted state to roll back.
 ## Configuration and capabilities
 | Setting/capability | Default | Profile | Runtime mutable | Effect |
 |---|---|---|---|---|
 | Forward/backward | Physical W/S | Current render sandbox | Yes, through Input Map | Produces signed forward axis |
 | Strafe left/right | Physical A/D | Current render sandbox | Yes | Produces signed right axis |
 | Camera rotate | Right mouse button | Current render sandbox | Yes | Captures/releases mouse for orbit |
 | Camera zoom | Mouse wheel | Current render sandbox | Yes | Adjusts current camera distance |
 | Debug sprint | Shift | Sandbox debug only by intent; profile gate pending | Yes | Requests existing speed multiplier |
 | Debug flight up/down/toggle | E/Q/Space | Sandbox debug only by intent; profile gate pending | Yes | Requests existing free-flight controls |
 ## Persistence, cache and migration
 The action names are additive project configuration. No saved binding schema,
 cache or migration exists yet. Renaming an action is a contract change and must
 provide a settings migration once user settings are persisted.
 ## Diagnostics and observability
 - Logs: dedicated verifier emits `PLAYER_INPUT PASS` or one failure per invariant.
 - Metrics: none; sampling cost is one small value allocation per physics tick.
 - Debug views: none.
 - Correlation IDs: not applicable to local synchronous input.
 ## Verification
 - Unit/contract tests: `src/tools/verify_player_input.gd` validates all actions,
  default bindings, axis cancellation/clamping/normalization and debug request flags.
 - Integration/E2E: `src/tests/scenes/player_input_regression.tscn` is loaded by
  the verifier, which drives forward, camera-zoom and immediate sandbox-flight
  actions through the real scene controller and also rejects direct
  physical-key polling.
 - Fidelity evidence: current sandbox defaults retain W/S/A/D, E/Q, Shift, Space,
  right mouse and wheel bindings. This is observable-regression coverage only.
 - Performance budgets: no I/O, jobs or scene lookup per sample; one immutable
  intent allocation per physics tick.
 - Manual diagnostics: run the Eastern Kingdoms scene and remap one movement
  action in Project Settings before checking movement.
 ## Extension points
 - A gamepad/accessibility adapter may call `compose_move_intent` without changing
  movement consumers.
 - A later input-context owner may suppress gameplay actions while preserving the
  same intent contract.
 - A future server-aware movement predictor may replace the current local
  movement consumer without changing `PlayerInputSource`.
 ## Capability status
 | Capability | Status | Evidence | Gap/next step |
 |---|---|---|---|
 | Remappable current sandbox controls | Implemented | `verify_player_input.gd` action/default checks | Add persisted user binding settings later |
 | `PlayerInputSource → MoveIntent` seam | Implemented | Pure composition and controller boundary checks | Local movement consumer is now extracted |
 | Exact 3.3.5a default semantics | Unknown | No original-client binding fixture in this package | Capture build-12340 defaults and mouse-turn/strafe policy |
 | Production profile exclusion of sprint/flight | Partial | Debug actions are named explicitly | Add typed profile/capability gate in M02 |
 | Jump/fall/swim/fly gameplay semantics | Planned | M02 target and gameplay roadmap | Implement after terrain/movement state extraction |
 ## Known gaps and risks
 - The defaults preserve the pre-M02 sandbox behavior, not verified original-client semantics.
 - Sprint and free flight are still executable by the sandbox controller until a
  typed build-profile gate is introduced.
 - Camera input is action-mapped but camera state/collision remains in the monolithic controller.
 - There is no persisted user keybinding format or UI yet.

 # Terrain Query
 ## Metadata
 | Field | Value |
 |---|---|
 | Status | Implemented |
 | Target/work package | M02 / M02-GMP-TERRAIN-QUERY-001 |
 | Owners | Gameplay terrain-query contract; ADT adapter owns parsed tile cache |
 | Last verified | `a45d521`, 2026-07-14 |
 | Profiles/capabilities | Current sandbox ADT ground height; renderer/physics backend planned |
 ## Purpose
 Provide a replaceable, scene-free ground-height query for player movement.
 Isolate native ADT loading, per-tile caching, chunk selection and legacy outer
 height-grid interpolation from the player scene behind a typed
 `GodotWorldPosition → TerrainGroundSample` contract.
 ## Non-goals
 - Own player transforms, movement velocity or ground-snap policy.
 - Provide collision normals, slopes, holes, liquids, WMO/M2 collision or ray queries.
 - Change ADT topology, coordinate conversion, renderer caches or native parser format.
 - Claim original-client terrain-contact parity from height regression alone.
 - Couple gameplay to the monolithic streaming renderer before a public backend exists.
 ## Context and boundaries

    Tile --> Cache[Owned tile cache]
    Cache --> Sample[TerrainGroundSample]
    Sample --> Scene

 ```
 Allowed dependencies:
 - Typed `GodotWorldPosition` and `CoordinateMapper` contracts.
 - Existing native `ADTLoader` at the ADT adapter boundary.
 - Dynamic dictionaries only inside the native-format adapter.
 - Player scene composition may inject any `TerrainQuery` implementation.
 Forbidden dependencies:
 - `TerrainQuery` contract depending on Nodes, cameras, input or renderer state.
 - Player scene loading/parsing ADT data or owning a parsed tile cache.
 - Manual WoW/Godot/ADT world-coordinate conversion outside `CoordinateMapper`.
 - Terrain query mutating transforms, gameplay movement state or visual meshes.
 ## Public API
 | Symbol | Kind | Purpose | Thread/lifetime | Errors |
 |---|---|---|---|---|
 | `TerrainGroundSample.available(height_units)` | Immutable value factory | Creates a finite Godot-world ground height | Any thread; caller-held value | Non-finite height becomes unavailable |
 | `TerrainGroundSample.unavailable(failure_code)` | Immutable value factory | Creates explicit unavailable result | Any thread; caller-held value | Empty code normalizes to `terrain_unavailable` |
 | `TerrainQuery.sample_ground_height(position)` | Replaceable boundary | Samples ground at typed Godot world position | Implementation-defined; current adapter main-thread owned | Base reports `terrain_query_not_implemented` |
 | `AdtTerrainQuery.new(extracted_directory, map_directory_name, loader_override)` | Adapter constructor | Configures one map and optional test/data-source loader | Query lifetime | Production validates native loader and file presence lazily |
 | `AdtTerrainQuery.sample_ground_height(position)` | Adapter method | Loads/caches tile and interpolates ADT outer heights | Main thread; cache lives with query | Returns stable failure code |
 | `ThirdPersonWowController.set_terrain_query(query)` | Composition method | Replaces terrain backend independently of movement/presentation | Call before scene ready or on main thread | Null is rejected and current query retained |
 ## Inputs and outputs
 | Direction | Contract/data | Producer | Consumer | Ownership | Thread/lifetime |
 |---|---|---|---|---|---|
 | Input | `GodotWorldPosition` | Player scene adapter | `TerrainQuery` | Immutable caller-held value | One query |
 | Input | Extracted directory/map name | Scene composition | `AdtTerrainQuery` | Copied strings | Query lifetime |
 | Input | ADT file/dictionary | Filesystem/native loader or injected loader | `AdtTerrainQuery` | Adapter-owned cached dictionary | Query lifetime |
 | Output | `TerrainGroundSample` | Terrain query | Player ground-snap adapter | Immutable caller-held value | One query |
 | Output | Failure code | Terrain query | Diagnostics/tests | Immutable `StringName` | Sample lifetime |
 Side effects:
 - Production adapter performs lazy file existence check and native ADT parse on first tile query.
 - Adapter mutates only its per-query tile/failure caches.
 - No scene tree, transform, renderer RID, network, database or persisted setting mutation occurs.

    TileAvailable --> [*]: query released
    TileUnavailable --> [*]: query released
 ```
 Unavailable tiles are cached intentionally to avoid repeated filesystem/native
 work each physics tick. Recovery after files appear requires replacing the query
 instance; hot-reload invalidation is outside this M02 package.
 ## Main sequence
 ```mermaid
 sequenceDiagram
    participant Player as ThirdPersonWowController
    participant Query as TerrainQuery
    participant ADT as AdtTerrainQuery
    participant Mapper as CoordinateMapper

    end
    ADT->>ADT: select chunk and interpolate heights
    ADT-->>Player: TerrainGroundSample
    Player->>Player: apply existing offset/snap if available
 ```
 ## Ownership, threading and resources
 - Player scene owns the active `TerrainQuery` reference.
 - `AdtTerrainQuery` exclusively owns tile/failure dictionaries until released.
 - Current production calls and cache mutations occur on the main physics thread.
 - Native loader result dictionaries do not cross the adapter boundary.
 - Samples and typed positions are immutable caller-held values.
 - The module creates no Nodes, Resources, RIDs or background jobs.
 - Future worker-backed queries require an explicit async/result contract rather
  than concurrent mutation of the current dictionaries.
 ## Errors, cancellation and recovery
 | Failure | Detection | Behavior | Diagnostic | Recovery |
 |---|---|---|---|---|
 | Base contract used directly | Base method | Unavailable sample | `terrain_query_not_implemented` | Inject implementation |
 | Native loader absent | ClassDB check | Cache unavailable tile | `adt_loader_unavailable` | Load extension and replace query |
 | ADT file absent | File check | Cache unavailable tile | `adt_source_missing` | Restore corpus and replace query |
 | Native parse empty/fails | Result validation | Cache unavailable tile | `adt_load_failed` | Inspect source/parser; replace query |
 | Injected loader returns wrong type | Type check | Cache unavailable tile | `adt_loader_result_invalid` | Fix adapter |
 | Chunk absent | Chunk lookup | Unavailable sample | `adt_chunk_missing` | Validate ADT dictionary |
 | Height array shorter than 145 | Size check | Unavailable sample | `adt_chunk_heights_invalid` | Fix parser/source |
 | Non-finite interpolated height | Sample invariant | Unavailable sample | `terrain_height_not_finite` | Inspect source values |
 | Null query injection | Scene guard | Existing query retained | Player composition error | Pass valid query |
 There are no asynchronous operations to cancel. Replacing/releasing the query
 is the deterministic cache-reset and recovery path.
 ## Configuration and capabilities
 | Setting/capability | Default | Profile | Runtime mutable | Effect |
 |---|---|---|---|---|
 | Extracted directory | Player `extracted_dir` | Current sandbox | Captured at creation | ADT source root |
 | Map directory name | Player `map_name` | Current sandbox | Captured at creation | ADT filename/path |
 | Loader override | Invalid callable | Test/custom data source | Constructor only | Bypasses production ClassDB/file loading |
 | Tile cache | Enabled | All current uses | Cleared by replacing query | Avoids repeated parse/failure work |
 | Height policy | 9x9 outer-grid bilinear | Current sandbox | Fixed | Preserves pre-extraction behavior |
 ## Persistence, cache and migration
 The cache is in-memory and unversioned because it holds native loader output for
 one query lifetime. No disk cache, schema or migration changes are introduced.
 Existing ADT/native/cache format versions remain unchanged.
 ## Diagnostics and observability
 - Logs: dedicated verifier emits `TERRAIN_QUERY PASS` or named failures.
 - Structured status: every unavailable sample has a stable `failure_code`.
 - Metrics: synthetic verifier counts loader calls to prove one load per tile.
 - Debug views: none.
 - Correlation IDs: not applicable to synchronous local query.
 ## Verification
 - Contract: available/unavailable/base/non-finite result invariants.
 - Pure synthetic adapter: typed coordinate mapping, exact chunk selection,
  145-height layout and bilinear interpolation within `0.002` units (Vector3
  source precision), plus cached second query.
 - Failures: empty tile and invalid height array produce stable codes.
 - Integration: asset-free player scene accepts injected flat query and preserves
  spawn offset `0.05` plus physics ground snap.
 - Boundary: source regression rejects ADT loader/cache/chunk helpers in player.
 - Fidelity evidence: existing interpolation and snap behavior only; no
  original-client or collision parity claim.
 - Performance budget: one dictionary cache lookup and scalar interpolation per
  cached query; native parse only on first tile access.
 ## Extension points
 - Streaming renderer or physics backend may implement `TerrainQuery` without changing player/movement.
 - Future result may grow separate slope, surface, liquid or collision contracts;
  incompatible additions require a versioned contract rather than Dictionary fields.
 - Test/authoring data sources may use constructor loader override.
 - Async streaming requires a separate availability/update model.
 ## Capability status
 | Capability | Status | Evidence | Gap/next step |
 |---|---|---|---|
 | Typed replaceable ground-height query | Implemented | Contract and injected player regression | Integrate target checklist after review |
 | Existing ADT height interpolation | Implemented | Synthetic fractional-grid fixture | Compare terrain contact with build 12340 |
 | Per-tile success/failure cache | Implemented | Loader call-count regression | Add explicit invalidation only with authoring/hot reload |
 | Renderer/streaming cache backend | Planned | Boundary permits replacement | M03 renderer facade/public terrain backend |
 | Holes/slopes/collision | Planned | Outside height-only contract | Later movement/physics package |
 | Liquid/swim query | Planned | Outside contract | M09/M12 world gameplay |
 ## Known gaps and risks
 - Bilinear outer-grid height is the inherited sandbox approximation; exact ADT
  triangle choice, holes and collision are not represented.
 - Query is synchronous; first access may parse an ADT on the main thread exactly
  as before extraction. A streaming/backend replacement is future work.
 - Unavailable results remain cached until query replacement.
 - Player still owns ground offset/snap policy; only data access is extracted.
 - Existing native dictionaries remain dynamic inside the adapter.
