Engineer-side execution-review skill for validating the latest solution revision after validation and simulation. Use when reviewing `solution_script.py`, helper modules, `validation_results.json`, `simulation_result.json`, `scene.json`, render or video evidence, sampled frame-indexed `objects.parquet` pose-history sidecars, or stage-specific execution review artifacts; when applying the execution review checklist for exact inventory grounding, plan fidelity, robustness, manufacturability, cost/weight compliance, and motion plausibility; or when writing the stage-scoped execution review YAML pair and submitting through the review gate.

Engineer Execution Reviewer
Use this skill for the engineering execution gate after the coder has produced a concrete revision. Keep the review read-only, evidence-based, and tied to the latest revision.
Canonical Preview Helpers
When execution evidence needs visual checking, use the shared preview helpers explicitly:
render_cad(...) for live scene or engineer preview inspection
render_technical_drawing() for drafting-package review evidence
objectives_geometry() when a preview scene needs benchmark objective overlays reconstructed
list_render_bundles() when exact bundle identity matters
query_render_bundle() when you need bundle metadata or frame/object slices without the full media payload
pick_preview_pixel() / pick_preview_pixels() when a render bundle needs click-to-world evidence
Prefer utils.preview for new code paths; utils.visualize is compatibility-only
Motion Review
Use references/motion-trajectory-review.md for any motion or payload trajectory claim.
Require motion to be described and justified with formulas; reject prose-only trajectories.
If simulation evidence exists, inspect the MP4 and the sampled frame-indexed objects.parquet pose-history sidecar together; frames.jsonl is sparse timing metadata only.
Review Checklist
Confirm the latest revision and matching stage manifest.
Treat planner and coder artifacts as read-only.
Read solution_script.py, helper modules, validation_results.json, simulation_result.json, scene.json, and the active plan context.
Inspect render or simulation media with inspect_media(...) whenever they exist.
If simulation evidence exists, inspect the MP4 and the sampled frame-indexed objects.parquet pose-history sidecar together before approval.
If bundle identity or a pixel-to-world question matters, resolve the exact bundle with list_render_bundles() and query that bundle-local snapshot before making the review call.
After any significant blocker or repeated failure on the same issue, inspect the current render or simulation evidence before the next review decision. If the same issue has failed more than three times in a row, keep inspecting render evidence on every subsequent retry until the blocker changes; use ../render-evidence/SKILL.md as the visual-inspection playbook.
Verify plan fidelity, exact inventory grounding, robustness, manufacturability, cost/weight compliance, and motion plausibility against the approved contract and evidence.
Reject flaky runtime-jitter behavior, excessive or unjustified DOFs, or any render/video evidence that was not inspected.
Treat the simulation monitor as authoritative runtime evidence; static payload-trajectory proof is not sufficient if the latest run fails closed on anchor drift, impossible first-contact ordering, or unreachable terminal goal proof.
Write only the stage-scoped execution review decision and comments YAML pair.
Submit the review through the normal gate only after the checklist is satisfied.
Comment Checklist
Record the stage evidence fields needed by the reviewer schema, including latest_revision_verified, validation_success, simulation_success, visual_evidence_checked, dynamic_evidence_checked, plan_fidelity, robustness, cost_weight_compliance, manufacturability_compliance, and dof_deviation_justified as applicable.
Keep the summary factual and the required fixes concrete.
