# M00-QAR-TERRAIN-HEIGHT-001 — Terrain height diagnostic
|
|
|
|
<!-- OPENWC_CLAIM:M00-QAR-TERRAIN-HEIGHT-001:sindo-main-codex:2026-07-13 -->
|
|

|
## Ownership
|
|
|
|
- Target: M00
|
|
- Program: QAR
|
|
- Owner/Agent ID: sindo-main-codex
|
|
- Branch: `work/sindo-main-codex/m00-terrain-height`
|
|
- Lease expires UTC: 2026-07-13
|
|
- Integrator: milestone integrator
|
|
|
|
## Outcome
|
|
|
|
Measure rendered terrain height and camera clearance at the five build 12340 golden checkpoints without changing renderer behavior.
|
|
|
|
## Non-goals
|
|
|
|
- Adding a runtime terrain-query API or collision system.
|
|
- Changing terrain geometry, coordinate mapping, placements, or cameras.
|
|
- Implementing the M01 CoordinateMapper.
|
|
|
|
## Paths
|
|
|
|
- Exclusive: `src/tools/probe_render_terrain_height.gd`
|
|
- Shared/hotspots: renderer baseline documentation and runner
|
|
- Generated/ignored: local JSON probe reports
|
|
|
|
## Contracts and data
|
|
|
|
- Public API/events: headless diagnostic CLI only
|
|
- Schema/format version: report schema 1
|
|
- Migration/compatibility: none
|
|
- Consumers: M00 fidelity diagnosis
|
|
|
|
## Dependencies
|
|
|
|
- Requires: calibrated renderer manifest and active terrain meshes
|
|
- Blocks: classification of under-terrain camera gaps
|
|
- External state: local extracted/cache data
|
|
|
|
## Verification
|
|
|
|
- Commands: terrain probe, M00 dry-run, coordination and documentation gates
|
|
- Fixtures: five calibrated manifest checkpoints
|
|
- Fidelity evidence: camera clearance against rendered OpenWC terrain
|
|
- Performance budget: offline diagnostic only
|
|
|
|
## Documentation deliverables
|
|
|
|
- Inline public API docs: script CLI header
|
|
- Module specification: verification/source map
|
|
- Data-flow diagram: terrain probe flow
|
|
- Sequence/state/dependency diagrams: synchronous diagnostic; not applicable
|
|
- Source map/status updates: baseline and renderer module
|
|
|
|
## Simplicity and naming
|
|
|
|
- Important names introduced: `terrain_height`, `camera_clearance`
|
|
- Simplest considered solution: CPU ray against already loaded mesh
|
|
- Rejected complexity/abstractions: new parser, physics collision, runtime query service
|
|
- Unavoidable complexity and justification: tile-local ray transform is required by mesh ownership
|
|
- Measured optimization evidence: not applicable
|
|
|
|
## Status
|
|
|
|
- State: ready
|
|
- Done: active-mesh terrain probe, four clearance measurements, isolated waterfall missing-mesh confirmation and documentation
|
|
- Next: integrator review; placement/composition diagnosis for four points and tile 30_49 ownership diagnosis remain separate packages
|
|
- Blocked by:
|
|
|
|
## Handoff
|
|
|
|
- Commit: branch HEAD
|
|
- Results: four cameras are 12.034..90.178 units above terrain; waterfall tile has no accessible terrain mesh after 10-second settle
|
|
- Remaining risks: mesh ray does not measure WMO/M2 occlusion; waterfall missing mesh requires streaming ownership investigation
|
|
- Documentation updated: `docs/RENDER_BASELINE.md`, `docs/modules/world-renderer.md`
