test(M00): calibrate paired renderer checkpoints

Work-Package: M00-QAR-VISUAL-DIFF-001
Agent: sindo-main-codex
Tests: synthetic JPG/PNG diff, manifest, coordination and documentation gates
Fidelity: five build 12340 references compared; coordinate and placement gaps recorded

 ## Status
 
 - State: ready
-- Done: comparator, runner integration, manifest tolerance contract, synthetic regression, module/baseline documentation, repository gates
-- Next: integrator review and paired run when approved build 12340 screenshots become available
+- Done: comparator, runner integration, manifest tolerance contract, synthetic regression, five local build 12340 references, three viewpoint calibrations, corrected visual capture and first paired report
+- Next: integrator review; coordinate/placement gap should be resolved before tolerance calibration
 - Blocked by: real paired screenshots only for final human fidelity approval
 
 ## Handoff
 
 - Commit: branch HEAD
-- Results: synthetic identical image passed, changed image failed; full M00 dry-run and repository gates passed
-- Remaining risks: thresholds need calibration against approved paired captures; animation phase and camera alignment still require human review
+- Results: ten pairs compared with no missing candidates; mean error 0.0707..0.1746 and changed ratio 0.5504..0.8187; human review identified under-terrain/inside-geometry camera mismatches
+- Remaining risks: coordinate/placement mismatch blocks meaningful tolerance calibration; synthetic animation, dusk and full human approval remain incomplete
