## Ownership

- Target: M00
- Program: QAR
- Owner/Agent ID: sindo-main-codex
- Branch: `work/sindo-main-codex/m00-camera-occluders`
- Lease expires UTC: 2026-07-13
- Integrator: milestone integrator

## Outcome

Report scene-tree M2/WMO geometry that contains calibrated cameras or intersects each camera-to-target segment.

## Non-goals

- Changing placements, cameras, FOV, culling, or renderer behavior.
- Claiming full coverage of RenderingServer RID-only instances.
- Implementing a production visibility or collision service.

## Paths

- Exclusive: `src/tools/probe_render_camera_occluders.gd`
- Shared/hotspots: renderer baseline documentation
- 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 workflow

## Dependencies

- Requires: calibrated five-point manifest and streaming scene
- Blocks: placement versus camera-composition classification
- External state: local extracted/cache data

## Verification

- Commands: camera occluder probe, coordination and documentation gates
- Fixtures: five calibrated camera/target segments
- Fidelity evidence: scene-tree bounds at paired build 12340 viewpoints
- Performance budget: offline diagnostic

## Documentation deliverables

- Inline public API docs: probe header and output fields
- Module specification: verification/source map
- Data-flow diagram: occluder probe flow
- Sequence/state/dependency diagrams: synchronous diagnostic; not applicable
- Source map/status updates: baseline findings

## Simplicity and naming

- Important names introduced: `camera_containing_geometry`, `segment_intersecting_geometry`
- Simplest considered solution: transformed published AABBs
- Rejected complexity/abstractions: GPU visibility readback or new BVH
- Unavoidable complexity and justification: RID-only geometry cannot be named by this probe
- Measured optimization evidence: not applicable

## Status

- State: ready
- Done: five-point scene-tree AABB probe, containment/intersection classification and documentation
- Next: integrator review; calibrate reproducible reference camera direction/FOV separately
- Blocked by:

## Handoff

- Commit: branch HEAD
- Results: zero containing geometry at all five cameras; expected WMO/liquid target intersections; ADT/dense segments unobstructed
- Remaining risks: RID-only instances are excluded; manual reference direction and FOV were not recorded exactly
- Documentation updated: `docs/RENDER_BASELINE.md`, `docs/modules/world-renderer.md`
