- parent: WBV2-P11-003
- status: in_progress
- gap: workflow:recompute_engine_module_gate
- ownerFamily: RELEASE
- targetImplementationClass: LOCAL_BOUNDED

## 目标

Recompute engine-bound module claims from P10 and P11 receipts without claiming whole-inventory completion.

## 输入与范围

- P10 engine receipt: `tests/golden/WBV2-P10-002/native-engine-receipt-report.json`
- P10 module matrix: `tests/golden/WBV2-P10-003/module-matrix-receipt-report.json`
- P11 Mesh/Modifier/Asset receipts
- Provenance approval: `docs/status/M12-PROVENANCE-EPOCH-2-APPROVAL.json`

## 验收

- `node tools/web/generate-wbv2-engine-module-gate.mjs --write`
- `node tools/web/check-task-context.mjs --task WBV2-P11-004 --write`

Missing receipt, hash drift, unsupported browser, false inventory completion, false historical reproduction, or undeclared capability claim must keep in_progress and must not advance nextTask.
