 # 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
 - Shared/hotspots: `src/scenes/player/third_person_wow_controller.gd`,
  `src/tools/verify_player_input.gd`,
  `src/tools/verify_coordinate_conversion_boundaries.gd`,
  `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.

 # M02-RND-CAMERA-001 — Third-person camera rig boundary
 <!-- OPENWC_CLAIM:M02-RND-CAMERA-001:sindo-main-codex:2026-07-16 -->
 ## Ownership
 - Target: M02
 - Program: RND/GMP
 - Owner/Agent ID: sindo-main-codex
 - Branch: `work/sindo-main-codex/m02-camera-rig`
 - Lease expires UTC: 2026-07-16
 - Integrator: M02 milestone integrator
 ## Outcome
 Move mouse capture, orbit yaw/pitch, zoom state and Camera3D transforms from
 `ThirdPersonWowController` into a reusable `ThirdPersonCameraRig`, with an
 explicit replaceable camera-collision policy that preserves the current
 no-collision sandbox baseline.
 ## Non-goals
 - Enable a new collision/raycast behavior before build-12340 comparison.
 - Change initial yaw/pitch, zoom limits, sensitivity, FOV, far plane or camera path.
 - Implement first-person, follow lag, shoulder offsets or cinematic cameras.
 - Change movement, terrain query, character presentation or renderer streaming focus.
 - Mark M02 complete or edit its checklist/Evidence.
 ## Paths
 - Exclusive: `src/scenes/player/third_person_camera_rig.gd`,
  `src/scenes/player/camera_collision_policy.gd`,
  `src/scenes/player/no_camera_collision_policy.gd`,
  `src/tools/verify_third_person_camera_rig.gd`,

  runtime streaming scenes, player regression scene,
  `src/tools/verify_player_input.gd`, `docs/modules/player-input.md`,
  `docs/modules/local-player-movement.md`, `docs/modules/README.md`
 - Generated/ignored: local `.godot`, native DLL, generated resources and renderer corpus
 ## Contracts and data
 - Public API: `ThirdPersonCameraRig.initialize_for_character`,
  `handle_camera_input`, `godot_world_flight_movement_basis`, state getters and
  `set_collision_policy`
 - Policy: `CameraCollisionPolicy.resolve_camera_distance`; default
  `NoCameraCollisionPolicy` returns requested distance unchanged
 - Scene paths and renderer camera path remain unchanged
 - Schema/cache/coordinate contracts: unchanged
 - Consumers: player composition, sandbox flight movement and renderer viewport
 ## Dependencies
 - Requires: merged TerrainQuery package on master `f5bb64e`
 - Blocks: character appearance/animation extraction from remaining player hotspot
 - External state: none; tests use asset-free camera/player scene
 ## Verification
 - Commands: dedicated orbit/zoom/clamp/policy verifier, input/movement/terrain
  regressions, asset-free scene, coordinate/StreamingFocus gates, renderer dry-run
  and repository gates
 - Fixtures: initial state, remappable action events, mouse deltas and fixed-distance policy
 - Fidelity evidence: preserve current `-18°` pitch, `8` distance, `1` zoom step,
  `2..18` clamp, `0.003` sensitivity and no-collision output
 - Performance budget: constant-time state/transform update; no raycast in baseline policy
 ## Documentation deliverables
 - Inline API/export documentation for rig and collision policies
 - Camera module spec with inputs/outputs, data-flow, state and sequence diagrams
 - Updated input/movement consumer diagrams/source maps and module registry
 ## Simplicity and naming
 - Important names: `ThirdPersonCameraRig`, `CameraCollisionPolicy`,
  `NoCameraCollisionPolicy`
 - Simplest approach: one Node3D rig on existing CameraPivot and one explicit identity policy
 - Rejected complexity: generic camera framework, spring arm migration and hidden physics raycast
 - Unavoidable complexity: rig mutates Camera3D/character Node transforms on main thread
 - Measured optimization evidence: not applicable
 ## Status
 - State: ready-for-review
 - Done: extracted rig and collision policy, migrated all three scene compositions,
  added regressions and completed required module documentation
 - Next: milestone integrator reviews and merges `8c1cf9b`
 - Blocked by:
 <!-- OPENWC_HANDOFF:READY:M02-RND-CAMERA-001:8c1cf9b -->
 ## Handoff
 - Outcome: `ThirdPersonCameraRig` now owns capture, orbit, zoom and camera
  transforms; `ThirdPersonWowController` only dispatches camera events and
  consumes the rig basis for sandbox flight.
 - Public contracts: `initialize_for_character`, `handle_camera_input`,
  `godot_world_flight_movement_basis`, `set_collision_policy`, read-only state,
  and `CameraCollisionPolicy.resolve_camera_distance`.
 - Verification: camera `state_cases=12 policy_cases=3 scenes=3`, input
  `actions=12 intent_cases=6`, movement `cases=12 state_transitions=2`, terrain
  `contract=4 interpolation=1 cache=1 failures=2`, coordinate boundary
  `files=98 consumers=5`; documentation, coordination and diff checks passed.
 - Renderer dry-run: seven checkpoint plans and report completed; expected
  diagnostics only for unavailable proprietary corpus/character GLB.
 - Fidelity: preserves the sandbox defaults (`-18 degrees`, distance `8`, zoom
  `2..18` step `1`, sensitivity `0.003`, pivot `1.7`, far `50000`) and the prior
  no-collision behavior. No build-12340 parity claim is made.
 - Local ignored inputs: native extension DLL and generated ADT resource scripts
  were used for the renderer dry-run and are not part of the commit.
 - Migration: none; `ThirdPersonPlayer/CameraPivot/Camera3D` remains stable.
 - Risks: active collision and exact original-client camera semantics remain
  unverified; exported initial values are captured at ready; mouse mode is
  process-global.
 - Documentation: added the camera API/module spec plus data-flow, state and
  sequence diagrams; updated player-input and local-movement consumer maps.

 # 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.

 - 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.

 | `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.

 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.

 ```
 ## 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.

 # Third-Person Camera
 ## Metadata
 | Field | Value |
 |---|---|
 | Status | Implemented |
 | Target/work package | M02 / M02-RND-CAMERA-001 |
 | Owners | Camera presentation state and CameraPivot/Camera3D lifecycle |
 | Last verified | `8c1cf9b`, 2026-07-14 |
 | Profiles/capabilities | Current sandbox orbit/zoom; identity collision policy |
 ## Purpose
 Own third-person mouse capture, orbit yaw/pitch, zoom state and Camera3D local
 transforms on the existing `CameraPivot` node. Expose an explicit replaceable
 camera-distance collision policy while preserving the current no-collision
 sandbox baseline.
 ## Non-goals
 - Implement an unverified physics raycast or claim build-12340 collision parity.
 - Own player movement, terrain queries, streaming focus or character visuals.
 - Implement first-person, follow lag, shoulder camera, cinematics or view modes.
 - Change current sensitivity, pitch/zoom limits, FOV or far plane.
 ## Context and boundaries
 ```mermaid
 flowchart LR
    InputMap[Remappable camera actions] --> Player[ThirdPersonWowController dispatch]
    Player --> Rig[ThirdPersonCameraRig]
    Mouse[Mouse motion] --> Player
    Rig --> Character[Character yaw transform]
    Rig --> Pivot[CameraPivot local transform]
    Rig --> Policy[CameraCollisionPolicy]
    Policy --> Distance[Resolved distance]
    Distance --> Camera[Camera3D local transform]
    Rig --> FlightBasis[Godot-world pivot basis]
    FlightBasis --> Movement[LocalPlayerMovementController adapter]
 ```
 Allowed dependencies:
 - Existing `PlayerInputActions` names and Godot input events.
 - Explicit character, pivot and Camera3D Node references on the main thread.
 - Replaceable `CameraCollisionPolicy` selected by composition/tests.
 - Movement adapter may read the rig's Godot-world basis during sandbox flight.
 Forbidden dependencies:
 - ADT/terrain parsing, movement velocity, gameplay state or animation ownership.
 - Camera rig discovering renderer/network/server services.
 - Default collision policy performing hidden raycasts or changing baseline distance.
 - Collision policy mutating rig/camera/character nodes.
 ## Public API
 | Symbol | Kind | Purpose | Thread/lifetime | Errors |
 |---|---|---|---|---|
 | `ThirdPersonCameraRig` | `Node3D` component | Owns orbit/zoom state on CameraPivot | Main thread; scene-owned | Reports missing Camera3D |
 | `initialize_for_character(character_body)` | Composition method | Attaches yaw target and captures initial character yaw | Main thread after scene ready | Null leaves yaw target absent |
 | `handle_camera_input(event)` | Input adapter | Applies capture/release/zoom/orbit actions | Main input thread | Returns whether camera consumed state |
 | `set_collision_policy(policy)` | Composition method | Replaces distance resolution policy | Main thread | Null rejected; old policy retained |
 | `refresh_camera_transform()` | Presentation update | Applies pivot pose and resolved camera distance | Main/physics thread | Missing camera leaves state but no Camera3D mutation |
 | `godot_world_flight_movement_basis()` | Read model | Returns pivot global basis for sandbox flight | Main thread | None |
 | `CameraCollisionPolicy.resolve_camera_distance(pivot, requested)` | Policy boundary | Resolves camera distance in Godot units | Main thread in current implementation | Rig clamps output to `[0, requested]` |
 | `NoCameraCollisionPolicy` | Identity policy | Preserves requested distance with no physics query | Any main-thread call | None |
 Read-only rig state: `yaw_radians`, `pitch_radians`,
 `requested_distance_units`, `resolved_distance_units` and `is_mouse_captured`.
 ## Inputs and outputs
 | Direction | Contract/data | Producer | Consumer | Ownership | Thread/lifetime |
 |---|---|---|---|---|---|
 | Input | Camera action `InputEvent` | Godot/player dispatch | Camera rig | Engine-owned event | One dispatch |
 | Input | Mouse relative pixels | Godot input | Camera rig | Engine-owned event | One dispatch |
 | Input | Character `Node3D` | Player composition | Camera rig | Scene-owned reference | Rig scene lifetime |
 | Input | Collision policy | Composition/test | Camera rig | Rig-held RefCounted | Until replacement |
 | Output | Character yaw | Camera rig | Player transform | Scene mutation | Orbit event |
 | Output | Pivot pitch/height | Camera rig | CameraPivot | Scene mutation | Refresh |
 | Output | Requested/resolved distance | Camera rig/policy | Camera3D | Rig-owned scalar/read model | Until next input/refresh |
 | Output | Godot-world `Basis` | Camera rig | Flight movement adapter | Value copy | Physics tick |
 Side effects:
 - Mutates mouse mode, character yaw, CameraPivot local transform and Camera3D local transform.
 - Marks Camera3D current and sets its far plane once at ready.
 - Releases captured mouse on rig removal.
 - Creates no files, caches, RIDs, workers, network messages or gameplay state.
 ## Data flow
 ```mermaid
 flowchart LR
    Action[Camera action or mouse delta] --> State[Yaw pitch requested distance capture]
    State --> Clamp[Pitch/zoom clamps]
    Clamp --> Pivot[Pivot height and pitch]
    Clamp --> Request[Requested distance]
    Request --> Policy[CameraCollisionPolicy]
    Policy --> Safe[Clamp 0..requested]
    Safe --> Camera[Camera3D Z distance]
    State --> Character[Character yaw]
 ```
 ## Lifecycle/state
 ```mermaid
 stateDiagram-v2
    [*] --> MouseVisible
    MouseVisible --> MouseCaptured: camera rotate pressed
    MouseCaptured --> MouseVisible: camera rotate released
    MouseCaptured --> MouseVisible: release cursor
    MouseCaptured --> MouseCaptured: mouse motion / orbit and clamp
    MouseVisible --> MouseVisible: zoom and clamp
    MouseCaptured --> [*]: rig removed / release mouse
    MouseVisible --> [*]: rig removed
 ```
 Zoom and collision distance are orthogonal to capture state. The requested zoom
 persists while a policy may temporarily choose a shorter resolved distance.
 ## Main sequence
 ```mermaid
 sequenceDiagram
    participant Engine as Godot Input
    participant Player as ThirdPersonWowController
    participant Rig as ThirdPersonCameraRig
    participant Policy as CameraCollisionPolicy
    participant Camera as Camera3D
    Engine->>Player: InputEvent
    Player->>Rig: handle_camera_input(event)
    Rig->>Rig: update capture/orbit/zoom state
    Rig->>Policy: resolve_camera_distance(pivot, requested)
    Policy-->>Rig: resolved distance
    Rig->>Camera: apply local position/rotation
    opt captured mouse motion
        Rig->>Player: mutate character yaw transform
    end
 ```
 ## Ownership, threading and resources
 - Parent player scene owns the CameraPivot rig and Camera3D child.
 - Rig holds non-owning scene references to character and camera.
 - Rig owns scalar camera state and the RefCounted collision policy.
 - All input/state/scene mutations occur on the main thread.
 - Policy output is a scalar; policies must not mutate supplied nodes.
 - No background tasks, resources, RIDs or caches are created.
 ## Errors, cancellation and recovery
 | Failure | Detection | Behavior | Diagnostic | Recovery |
 |---|---|---|---|---|
 | Camera3D missing | `_ready` lookup | State continues; transform application skipped | `ThirdPersonCameraRig` error with path | Restore child/path and recreate scene |
 | Character missing | Initialization | Orbit state updates without character yaw mutation | Composition/test failure | Call initializer with player node |
 | Null collision policy | Setter guard | Current policy retained | Rig error | Pass valid policy |
 | Policy returns negative/too large | Rig clamp | Distance clamped to `[0, requested]` | Policy regression tests | Fix/replace policy |
 | Rig removed while captured | `_exit_tree` | Mouse made visible | Lifecycle regression | Recreate rig normally |
 There is no asynchronous cancellation or persisted rollback. Recreating the rig
 restores configured defaults.
 ## Configuration and capabilities
 | Setting/capability | Default | Profile | Runtime mutable | Effect |
 |---|---|---|---|---|
 | Initial pitch | `-18°` | Current sandbox | State-owned after ready | Initial orbit elevation |
 | Pitch limits | `-65°..35°` | Current sandbox | Exported | Mouse clamp |
 | Mouse sensitivity | `0.003` rad/pixel | Current sandbox | Exported | Orbit delta |
 | Pivot height | `1.7` units | Current sandbox | Exported | Camera eye origin |
 | Initial distance | `8` units | Current sandbox | Exported before ready | Requested zoom |
 | Zoom limits/step | `2..18`, step `1` | Current sandbox | Exported | Requested distance clamp |
 | Far plane | `50000` units | Renderer sandbox | Exported | Camera far plane |
 | Collision policy | `NoCameraCollisionPolicy` | Current sandbox | Replaceable | Identity distance/no raycast |
 ## Persistence, cache and migration
 Camera state and policy are transient. No SavedVariables/settings schema, cache
 or migration is introduced. Scene paths remain
 `ThirdPersonPlayer/CameraPivot/Camera3D`, so renderer diagnostics and capture
 tools require no path migration.
 ## Diagnostics and observability
 - Logs: missing camera/null policy emit explicit component errors.
 - Read models: yaw, pitch, requested/resolved distance and capture state.
 - Tests: dedicated verifier reports state/policy/scene counts.
 - Metrics/correlation IDs: not applicable to constant-time local presentation.
 ## Verification
 - State regression: initial yaw/pitch/distance/height/far plane, capture/release,
  mouse orbit, character yaw, pitch clamps and zoom clamps.
 - Policy regression: fixed-distance test policy changes Camera3D Z; identity
  policy restores requested distance; baseline policy contains no physics query.
 - Scene integration: Eastern Kingdoms, Kalimdor and asset-free regression scenes
  attach the rig to the existing CameraPivot.
 - Boundary: player no longer owns capture/yaw/pitch/distance or camera transform helper.
 - Existing input/movement/terrain regressions and renderer dry-run remain required.
 - Fidelity evidence: current numeric defaults and identity collision behavior
  only; original-client orbit/collision comparison remains open.
 - Performance: constant-time scalar/transform work once per physics tick and
  input event; no default raycast.
 ## Extension points
 - Add an opt-in raycast collision policy after reference fixtures define mask,
  margin, recovery smoothing and first-person limit.
 - Add follow/shoulder/cinematic rigs as separate components, not branches inside this rig.
 - Persist user camera settings through a future versioned settings module.
 - Input contexts may suppress camera actions before dispatch without changing rig state.
 ## Capability status
 | Capability | Status | Evidence | Gap/next step |
 |---|---|---|---|
 | Independent third-person rig | Implemented | Three scene wirings and player boundary regression | Integrate target checklist after review |
 | Existing orbit/zoom behavior | Implemented | Numeric state/transform regression | Compare against build 12340 |
 | Camera-relative sandbox flight basis | Implemented | Basis and movement regressions | Restrict flight to sandbox profile |
 | Replaceable collision policy | Implemented | Fixed and identity policy tests | Implement verified collision policy |
 | Active camera collision | Planned | Identity policy intentionally preserves baseline | Capture original-client occluder fixtures first |
 | First-person/follow policies | Planned | Outside current sandbox baseline | Later completeness work |
 ## Known gaps and risks
 - Default collision policy performs no occluder avoidance, matching the previous sandbox.
 - Exact WoW camera orbit direction, pitch limits, zoom curve, collision margin and
  recovery smoothing are unverified.
 - Exported initial values are captured at ready; runtime mutation may require an
  explicit reconfiguration API later.
 - Mouse mode remains process-global Godot state and must be coordinated with future UI contexts.
