+# Final cross-feature fix wave report
+
+Base: `9ace0fb`  
+Code commit: `9ae498a`  
+
+## Addressed blockers
+
+- Staged assembly now aggregates every ordered page read, uses first-nonempty header evidence, preserves every extracted line, persists line links and the complete canonical check list, and marks a candidate ready only when PO/site/supplier/item/check gates are satisfied.
+- Added a two-page continuation regression proving that distinct lines on both pages survive aggregation.
+- Manual assembly split/join now clears derived document identity, supplier/PO relations, items, checks, match evidence, candidate identity, and posting relation for every affected nonterminal candidate. New candidates start `needs_review`; posted/dismissed candidates remain protected.
+- Added optional `global_page` to canonical pages, assigned during staged normalisation, with a batch-wide unique index. Posting and page proxy lookup use it. Legacy rows are remapped only when source ordinal/page identities are contiguous and unique; mixed or gapped rows fail closed.
+- Added a missing-middle-page posting regression: persisted global pages 1 and 3 with candidate `[3]` selects page 3.

+
+## Residual risk
+
+The migration remains unapplied and `DN_STAGED_INGESTION_ENABLED` remains unchanged. Existing rows without `global_page` and with a source-page gap require manual repair/re-extraction; the posting path intentionally refuses to infer their identity.

+Ruling: staged candidates must persist the aggregate page evidence, line links, and complete canonical checks before they can be ready_to_post — cost if wrong: more candidates enter review, but no incomplete candidate can pass the posting gate.
+Ruling: global_page is an additive stable identity and legacy page remapping is allowed only when source ordinals/pages are contiguous and unambiguous — cost if wrong: old ambiguous rows require manual repair instead of risking the wrong scan page.
+Ruling: manual split/join invalidates all derived candidate commercial/entity/match/check fields and requires recomputation — cost if wrong: an operator must wait for the staged runner, but stale PO links cannot be posted after page reassignment.
