description: Turn multiview fit reports into a sequential or parallel repair queue for aligning Blender products to source-of-truth templates. Use after validation shows disalignment, when the agent must iteratively fix wireframe, texture, lighting, or projection mismatches, and when a recurring failure should stop the rebuild loop for a diagnosis.
when_to_use: Iterative source-of-truth alignment repair, choosing sequential vs parallel correction order, generating fit repair queues, stopping on contradictory templates, or coordinating geometry/UV/lighting fixes from validation reports.

# Fit Repair Optimizer

This skill converts validation failures into an executable repair queue. The source templates are the contract; the current model is disposable.

## Decision: sequential or parallel?

Use **sequential repair** when failures are coupled:

1. Canonical view / source conflict unresolved.
2. Front silhouette or part count fails.
3. Geometry dimensions fail before UVs can be trusted.
4. Texture region boundaries depend on geometry changes.
5. Lighting/look depends on final material placement.

Use **parallel repair** only for independent tracks with disjoint write scopes:

- geometry recipe/placement tuning;
- atlas-region classification;
- material/look calibration;
- validation tooling improvements.

Do not parallelize two tasks that both edit the same Blender recipe, object transforms, or UV assignment file.

## Mandatory repair order

```
0 source-conflict / multiview-rigidity gate
1 structural part count
2 front silhouette and landmarks
3 side/back/top depth and projection
4 UV/texture region fit
5 material/light/look calibration
6 export and final validation
```

If an earlier stage fails, later stages may be analyzed but must not be finalized.

## Source-conflict gate

Before repair, use `multiview-constraint-solver` to check whether templates are mutually satisfiable. If the same physical axis receives incompatible ratios across views, write a conflict report and require a canonical policy:

- front+side canonical;
- front+top canonical;
- corrected template sheet;
- view-specific cheat renders only, not a rigid 3D model.

## Repair queue schema

Each repair item must include:

- `id`
- `stage`
- `view_scope`
- `failure`
- `measured_delta`
- `proposed_action`
- `write_scope`
- `parallel_group`
- `blocked_by`
- `acceptance_gate`

## Skill-gap rule

If the same failure recurs twice, stop and invoke `quality-refinement-autoloop` before another rebuild. The autoloop must capture evidence, diagnose the missing method and record the lesson, then return here with a new repair queue. It does not edit skill files. Common routing:

- geometry mismatch → `contour-to-mesh`, `orthographic-registration`, or this skill;
- UV/texture mismatch → `atlas-uv-fitting`;
- lighting mismatch → `reference-look-calibration`, then `blender-lighting`;
- validation mismatch → `multiview-fit-loop` / `reference-analysis-validator`.

## Output

Write a project repair plan such as `ALIGNMENT_REPAIR_QUEUE.json` and a human-readable `ALIGNMENT_REPAIR_METHOD.md`.
