ChangeSet Audit Logs & Same-Camera Cycles Pixel Diff: Delivering with Evidence
When delivering a revised V3 model, how can reviewers instantly verify what changed and prove that untouched areas remained intact?
Traditional 3D handoffs rely on a vague "Fixed, see attached file," forcing reviewers to manually compare massive files by eye. VECTOR attaches two pieces of hard evidence to every derived version: 1. A structured **`ChangeSet` audit record** (parent/output versions, executor, modified parts, protected parts, and metric deltas); 2. **Same-Camera Cycles Pixel Diff**, quantifying visual change ratios and hotspots while supporting one-click non-destructive rollback.
The method: three small steps
Delivering with evidence rests on three mechanisms: 1. **`ChangeSet` Integrity Check**: verifies parent hash lineage, modified part alignment with the `EditPlan`, and zero drift on protected parts; 2. **Same-Camera Cycles Pixel Diff**: renders before-and-after versions under identical camera and lighting matrices to compute pixel diff percentage and bounding regions; 3. **Append-Only Rollback**: rolling back copies the prior version’s bytes into a new latest version (e.g., V3 → V4) so history is never overwritten.
Audit the ChangeSet record (parent version, executor, modified parts, deltas)
Verify that the ChangeSet logs the V1 parent hash, V2 output hash, executor ID (`blender-worker`), and exact vertex/triangle/bounding-box deltas.
Run Same-Camera Cycles Rendering Pixel Diff
Render V1 and V2 from the exact same camera matrix to measure pixel diff ratio (e.g., `4.8%`) and hotspot bounds—proving changes are confined to the target part.
Sign off on Requirement Consistency QA or trigger append-only rollback
Sign off on the delivery package once all evidence aligns—or roll back by archiving V1 bytes as a new V3 record without erasing V2 history.
In the ChangeSet Audit & Cycles Pixel Diff Inspector below, review the V1 → V2 modification evidence for Tatami Room (3acfc61e).

Tatami Room (3acfc61e) completed a V1 → V2 tokonoma pillar resize and material update. Choose the final delivery sign-off method.
Switch to the recommended VECTOR controlled pipeline option to resolve topology, UV, or QA gate errors.
Never deliver a bare GLB file alone; deliver the model paired with its `ChangeSet` metric deltas, same-camera Cycles Pixel Diff evidence, and an append-only rollback chain.
Run it in the VECTOR 3D workbench or Blender pipeline
- Open a matching reference asset in the VECTOR 3D workbench or your Blender + AI pipeline.
- Copy the task sheet below, let AI generate an inspectable checklist or EditPlan first, and confirm before running mesh or material operations.
How does VECTOR’s version management handle rolling back an asset from V2 to V1?
