+## 2.22.1 — Live PostgreSQL proof of imported primary Voice history
+
+- Synthetic PostgreSQL integration tests prove ADR 0252 A → B → A primary
+  Voice history at before, between, and after knowledge cutoffs, concurrent
+  `voc_type_code` updates, GiST non-overlap, closing a matching additional
+  assignment, and 0237 then 0243 trigger replay. Live post reads use
+  `effective_to IS NULL`; cutoff reads use half-open interval containment;
+  ontology continuation uses frozen `snapshot_at` when no cutoff is
+  requested. Tests skip without PostgreSQL. Do not close #748 until
+  protected delivery.

 | Image understanding | Region, OCR, and description work exists across active heads (#405, #419), but current runtime acceptance has not yet proved table-image structure, complete region coverage, or summary/image readiness together | Orchestrator-backed rendered workflow, original/derived asset provenance, region-before-OCR processing, and honest unsupported states; reconcile ADR 0052's image-bearing summary readiness with ADR 0098 before changing sequencing |
 | Semantic source rendering | Paragraph, table, list, formula, and indentation work exists across stacks (#394, #427, #448–#450); #515 adds synthetic backend/frontend parity for deterministic rows/cells, footnote boundaries, and encoded scripts | Land the #427 → #515 stack, then gather authenticated browser evidence that list nesting, continuation alignment, and formula units render without authoring-layout artifacts |
 | Event and project semantics | #663 is the largest current user-visible gap slice: evidence-backed Project nodes, bounded traversal, cutoff/snapshot fencing, exact-value table parity, and localized graph labels. Focus visibility, label-bound, and temporal test-double regressions are repaired. #666's heuristic removal is composed into this parent but is not separately protected-main evidence. #640 separately adds project journeys without claiming authoritative lifecycle status | Combined #663 must pass exact-head checks and independent approval before protected merge. Aggregate authenticated evidence must still prove distinct projects/events and handover intervals without promoting co-occurrence |
-| Voice primary history | The #717 candidate updates ADR 0256 and migration 0237 with immutable assignment ids and half-open intervals, closing rather than deleting a replaced primary so A → B → A is representable; this is not protected-main evidence | Prove migration replay, concurrent primary changes, non-overlap, and API/ontology cutoff reads against synthetic PostgreSQL at the current exact head, then close #748 only after protected delivery |
+| Voice primary history | Protected `main` `bbb19192` includes ADR 0252 / #761 (migration 0243, GiST primary-period exclusion, `clock_timestamp()` after the source-row lock, API/ontology half-open cutoff SQL). v2.22.1 adds synthetic PostgreSQL integration tests for A → B → A at before/between/after cutoffs, concurrent primary updates, additional-assignment close, and 0237→0243 trigger replay. This is not yet protected-main evidence | Land the live-test slice through the protected gate with independent exact-head APPROVE; close #748 only after that protected delivery |
 | Knowledge Graph readability | #659 recreates the token-backed node-type repair on current `main`, including regression coverage; it is open and therefore not protected-main evidence | Merge #659 normally, then verify light/dark contrast, keyboard graph navigation, full labels, and evidence tables in the authenticated rendered surface |
 | Source-code lookup UX | Source state/detail codes remain evidence-bearing machine values and current detail presentation is dense | Catalog-backed display labels with raw-code provenance, compact 5W1H/source-detail hierarchy, keyboard access, and no unsupported customer/project binding |
 | Calendar / Naruon | #355 delivered the projection contract; v2.17.0 wires operator consumption without forwarding the end-user token. Naruon producer, provider/consumer fixtures, and protected merge remain open (#336) | Verify observed events against the published schema without invented events; keep commitments available when the channel is unwired |
