## Ownership

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

## Outcome

Produce one final WMO-ready paired report for all available build 12340 references and reconcile the remaining M00 acceptance gaps.

## Non-goals

- Achieving renderer parity inside M00.
- Calibrating unknown manual camera parameters.
- Marking the target DONE; only the milestone integrator may do so.

## Paths

- Exclusive: paired-run exit handling and final evidence record
- Shared/hotspots: renderer baseline/module findings
- Generated/ignored: final captures and reports under `user://`

## Contracts and data

- Public API/events: visual comparison exit 0/1 both count as completed report generation
- Schema/format version: unchanged
- Migration/compatibility: comparator infrastructure errors remain fatal
- Consumers: M00 integrator

## Dependencies

- Requires: merged region diagnostic and five private reference images
- Blocks: integrator decision on M00 completion
- External state: private images remain outside Git

## Verification

- Commands: complete paired baseline run, report audit, repository gates
- Fixtures: five build 12340 references
- Fidelity evidence: cold/warm comparison metrics and human gap classification
- Performance budget: existing M00 capture budgets

## Documentation deliverables

- Inline public API docs: PowerShell comparison step semantics
- Module specification: final evidence status
- Data-flow diagram: unchanged
- Sequence/state/dependency diagrams: unchanged
- Source map/status updates: baseline acceptance summary

## Simplicity and naming

- Important names introduced: `Invoke-GodotComparisonStep`
- Simplest considered solution: allow only comparator exit codes 0 and 1
- Rejected complexity/abstractions: suppressing all process failures
- Unavoidable complexity and justification: threshold exceedance is evidence, not infrastructure failure
- Measured optimization evidence: not applicable

## Status

- State: ready-for-review
- Done: paired-run exit contract fixed; full baseline and visual capture completed; ten pairs audited; final acceptance document written
- Next: integrator decides animated/sky reference policy and GUI RID-risk disposition
- Blocked by:

## Handoff

- Commit: this work-package commit
- Results: compared=10, failed=10, missing=0; mean error 0.066892..0.176952; cold/warm gaps stable; full workflow returned success with threshold evidence preserved
- Remaining risks: no build 12340 animated-M2 or sky-transition reference; GUI renderer RID/resources still reported at exit
- Documentation updated: `docs/M00_FINAL_PAIRED_EVIDENCE.md`, `docs/modules/world-renderer.md`
