# Sweep 012 Materialization Recovery Design

> Date: 2026-04-20
> Parent Plan: `2026-04-19-scene-skill-102-final-materialization-plan.md`

## Intent

Recover the single failed final materialization package:

`sweep-012-scene / 业扩报装管理制度`

The official framework board expects this scene to be `paginated_enrichment / A`, but final materialization fell into `host_bridge_workflow / C` and failed before writing required skill files.

## Scope

Allowed:

1. Diagnose why this one scene materializes as `host_bridge_workflow`.
2. Apply the smallest bounded correction needed for this scene to materialize.
3. Re-run only `sweep-012-scene` into the existing final materialization root.
4. Refresh final materialization manifest, failures asset, human-readable index, and deterministic readiness for this scene.
5. Publish a recovery report.

Forbidden:

1. Do not rerun all 102 scenes.
2. Do not change other scene packages unless shared metadata refresh requires aggregate indexes.
3. Do not start static, mock, or production validation.
4. Do not update the official execution board.
5. Do not create a new family.

## Completion Criteria

1. `sweep-012-scene` has `SKILL.toml`, `SKILL.md`, `scene.toml`, and at least one script.
2. `sweep-012-scene` deterministic suffix is `。。。`.
3. Full-name deterministic dispatch selects `sweep-012-scene`.
4. Final materialization failure count becomes `0`.
