## Ownership

- Target: M00
- Program: QAR
- Owner/Agent ID: sindo-main-codex
- Branch: `work/sindo-main-codex/m00-camera-pose-evidence`
- Lease expires UTC: 2026-07-14
- Integrator: milestone integrator

## Outcome

Produce coarse-to-fine yaw/pitch evidence for the build 12340 Goldshire Inn reference and classify whether framing dominates the paired-image gap.

## Non-goals

- Changing manifest camera defaults before human approval.
- Treating minimum perceptual error as proof of exact camera parity.
- Committing proprietary reference images or generated candidates.

## Paths

- Exclusive: camera-pose evidence record
- Shared/hotspots: renderer baseline and module fidelity findings
- Generated/ignored: all sweep PNGs and JSON under `user://`

## Contracts and data

- Public API/events: none
- Schema/format version: unchanged
- Migration/compatibility: none
- Consumers: M00 fidelity review

## Dependencies

- Requires: merged camera-pose sweep and local build 12340 reference
- Blocks: classification of the Goldshire WMO paired gap
- External state: `sources/OpenWCReferenceCheckpoints/goldshire_inn_large_wmo.jpg`

## Verification

- Commands: coarse and fine real sweeps, ranking inspection, repository gates
- Fixtures: private Goldshire Inn build 12340 screenshot
- Fidelity evidence: ranked mean perceptual error and changed-pixel ratio
- Performance budget: offline diagnostic only

## Documentation deliverables

- Inline public API docs: unchanged
- Module specification: fidelity finding and remaining risk
- Data-flow diagram: unchanged
- Sequence/state/dependency diagrams: unchanged
- Source map/status updates: baseline evidence

## Simplicity and naming

- Important names introduced: none
- Simplest considered solution: use the merged bounded grid runner
- Rejected complexity/abstractions: optimizer or renderer changes
- Unavoidable complexity and justification: real images must be rendered for each candidate
- Measured optimization evidence: single pass per candidate

## Status

- State: ready-for-review
- Done: private reference dimensions verified; coarse, extended and limit sweeps completed; representative candidates inspected; runner failure handling hardened
- Next: investigate Goldshire Inn spatial/placement composition separately; do not change manifest yaw/pitch from this metric
- Blocked by:

## Handoff

- Commit: this work-package commit
- Results: zero offset mean error 0.099632; coarse best (-10,-20) 0.077575; metric decreased monotonically to (0,-60) 0.063574/changed ratio 0.549556, while visual inspection showed only grass and no inn
- Remaining risks: full-frame color error cannot register a missing landmark; WMO placement/streaming at this checkpoint remains unresolved
- Documentation updated: `docs/CAMERA_POSE_SWEEP.md`, `docs/modules/world-renderer.md`
