+# M00-QAR-FINAL-PAIRED-EVIDENCE-001 — Final paired evidence audit
+
+<!-- OPENWC_CLAIM:M00-QAR-FINAL-PAIRED-EVIDENCE-001:sindo-main-codex:2026-07-14 -->
+
+## 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`

+# M00 Final Paired Evidence — 2026-07-12
+
+## Scope and result
+
+The final local M00 audit used Godot 4.6.1, the existing cache state, the manifest-standard 8-second readiness wait, and `2560x1440` visual candidates. Five private WoW 3.3.5a build 12340 references produced ten cold/warm comparisons with no missing pair. Private images and generated reports remain outside Git.
+
+The command completed even though every pair exceeded the strict regression tolerance. Comparator exit code `1` means a valid report with visual gaps; only codes outside `0/1` are infrastructure failures.

+
+| Checkpoint | Pass | Mean perceptual error | Changed-pixel ratio | Classification |
+|---|---|---:|---:|---|
+| `elwynn_adt_boundary` | cold | 0.087347 | 0.634984 | Composition plus terrain/vegetation/material gaps |
+| `elwynn_adt_boundary` | warm | 0.087255 | 0.634598 | Stable against revisit |
+| `elwynn_terrain_overview` | cold | 0.174136 | 0.851806 | Largest composition/framing gap |
+| `elwynn_terrain_overview` | warm | 0.176952 | 0.861275 | Stable gap, not a cold-load artifact |
+| `elwynn_waterfall_liquid` | cold | 0.088526 | 0.706897 | Framing, terrain, liquid and lighting gaps |
+| `elwynn_waterfall_liquid` | warm | 0.087490 | 0.695281 | Stable against revisit |
+| `goldshire_dense_m2` | cold | 0.066892 | 0.575205 | Smallest available paired gap; vegetation/material differences remain |
+| `goldshire_dense_m2` | warm | 0.066927 | 0.575547 | Stable against revisit |
+| `goldshire_inn_large_wmo` | cold | 0.101230 | 0.701836 | WMO is ready; manual framing and presentation gaps remain |
+| `goldshire_inn_large_wmo` | warm | 0.101203 | 0.701855 | Stable against revisit |
+
+Cold and warm values are close for all five references. The paired gaps are therefore not explained by first-visit cache readiness. Goldshire timing evidence separately demonstrated that the 8-second wait is necessary for WMO publication.
+
+## Fidelity interpretation
+
+M00 now has reproducible quantitative evidence for terrain, ADT boundary, dense M2, large WMO and liquid checkpoints. The reports demonstrate current differences; they do not claim renderer parity. Camera calibration experiments also show that unknown manual yaw/pitch/FOV cannot be recovered reliably from full-frame color error alone. Region scoring reduces terrain bias but still requires semantic landmark approval.
+
+Two manifest checkpoints still lack original-client paired references:
+
+- `gryphon_roost_native_animation` is a synthetic native-animation probe and has no matching build 12340 fixture.
+- `elwynn_sky_dusk` has no approved build 12340 sky-transition fixture at the same time/weather state.
+
+These must either receive private reference evidence or be explicitly accepted by the milestone integrator as unpaired diagnostic coverage. Until that decision, the target remains `ACTIVE`.
+
+## Operational risks
+
+The full GUI capture completed and wrote both reports, but Godot still emitted renderer RID/resource leak diagnostics at exit. The earlier anonymous headless `RefCounted` leak is fixed; GUI renderer allocations are a distinct known risk. They do not invalidate the written images or metrics, but must remain recorded rather than hidden.
+
+## Integrator decision checklist
+
+- Five available reference checkpoints: paired cold/warm report complete, missing pairs zero.
+- Animated M2 fixture: missing or explicitly accepted as synthetic-only.
+- Sky-transition fixture: missing or explicitly accepted as unpaired.
+- Renderer visual differences: registered as gaps, not parity claims.
+- GUI renderer RID/resource diagnostics: accepted as a tracked risk or assigned a follow-up blocker.
+- Target status and `OPENWC_TARGET_DONE` marker: integrator-only action.
