Draft migration: merge only after the owner's explicit yes to this database change. Snapshots the worker-owned documents.metadata keys and the document_index_quality row per committed generation through two triggers, and makes rollback_document_index_generation restore them (refusing with target_snapshot_missing when no snapshot exists). Retires the --i-understand-metadata-not-restored guard in reindex:rollback.

…3732) The #3718 rollback SQL test moved the pointer without a quality row, so after #3732 its happy path hit target_snapshot_missing by design. Commit generations as the worker does (quality upsert, then metadata with the pointer), add a target_snapshot_missing case, and assert the rollback and roll-forward restore each generation's metadata and quality while keeping owner-edited keys.

- extraction:provenance: the 'not recorded' filter now matches the same documents its counts show (including documents with no provenance block), and paging uses an id keyset so concurrent writes cannot shift a page. - Contract test: the live commit_document_index_generation upserts quality before it moves the pointer, which the #3732 quality snapshot relies on. - Hostile-document test: escape the zero-width characters, assert the forged opening fence is escaped, and assert the hidden white-text instruction reaches the model only inside an unbroken source fence.

Summary
Code Review ✅ Approved 1 closed / 1 findings🔴 High risk · The database migration adds snapshot triggers and changes rollback restoration; faulty captures could restore mismatched document metadata or index-quality state. Index rollback now restores the target generation's worker-owned metadata and index quality alongside the pointer, and extraction provenance records chunker and OCR versions. The dry run no longer reports 'would roll back' for targets with no snapshot, which was the one issue raised and is now resolved. No open findings remain. ✅ 1 closed✅ Edge Case: Dry run reports 'would roll back' for targets with no snapshot

Index rollbacks now restore the target generation's worker-owned metadata and index quality alongside the generation pointer, instead of leaving them describing the newer generation. The PR also records chunker and OCR versions in extraction provenance and runs the hostile-document matrix through the real PDF reader. No retrieval behavior changes — only metadata keys are added at commit time.
