# Stage 5R2 + Stage 5R2b Regression Review

## Bottom-line disposition

**Almost closed, but not clean enough to say Stage 6 charters should begin immediately.**
I would do a tiny **Stage 5R2c cleanup patch** first. No broad re-review needed.

The major Stage 5R2 / 5R2b architecture is sound. The remaining issues are stale cross-artifact residue and one Owner Map cleanup problem, not structural reversals.

## Question A — Stage 5R2 exit check

A1. ✅ closed — OP-A staleness is substantively resolved: OPA-001/004/005/011/012 were rewritten, and OPA-031–034 added.

A2. ⚠️ partially closed — Most one-owner violations are fixed, but `ApprovedSafeLabelVocabularyRegistry` still has owner `PropA / EC`; under the one-owner rule, that should be one schema owner plus executor/consumer notes.

A3. ✅ closed — Import graph edge-kind ambiguity is resolved by splitting `schema_import`, `runtime_instance_flow`, `command_or_control_flow`, and `storage_or_execution_flow`; acyclicity is asserted only for schema imports.

A4. ✅ closed — DOC83 → DOC87 ordering is resolved through the `TopicIdentityContract` / membership-target stub requirement before DOC83’s TopicCollectionDirective drafting.

A5. ⚠️ partially closed — DOC85 rows are corrected, but `MemoryFlowCertificate` still lists `DOC8` as an executor, which conflicts with “DOC8 = capability-mining only.”

A6. ✅ closed — DOC82↔DOC83 disposition/resolution seam is explicit: DOC83 emits recommended disposition; DOC82 owns resolution, dedupe, and the anti-overlap rule.

A7. ✅ closed — SM-202 / DR-006 are corrected to the actual ABC §7.8 values, and the conflict register records the corrected resolution.

A8. ⚠️ partially closed — Owner Map / §10.8 resolve VersionedClaim and WorkSession, but skeletal §4.6 still carries stale “pending matrix-gap dispositions” language. Clean that stale paragraph before Stage 6.

A9. ✅ closed — EC seam is named as `ECSeamContract`, EC is marked partial/moving, and OPA-031 carries the detailed write / policy / membership / learning / concurrency obligations.

A10. ⚠️ partially closed — The DOC87 plan amendment landed, but skeletal §3.2 still says “BDSM / DOC8 … dependency_status pending ADQ-221,” despite ADQ-221 being resolved.

A11. ✅ closed — ADQ-222 is open and explicitly gates possible Stage 7 schema-body work for published/shared surfaces.

A12. ✅ closed — DOC80-core V5 non-goal and manual-deletion sentences are present in skeletal §10.1 and §10.2.

A13. ✅ closed — `LegalHoldState` flag and invariant are present, with OPA-033 wiring destructive-job checks.

## Question B — Stage 5R2b fold-ins

B1. ✅ closed — `NonAssertionExtractionOutcome` → `AlternativeExtractionRouting` and `SourceBoundSynthesisProjection` → `SourceBoundSynthesisAdapter` are semantically better names and are cascaded through skeletal / Owner Map / Retired Names / OP-A references.

B2. ✅ closed — `SemanticProjection` is narrowed into `SemanticProjectionContract` plus Delivery / UI / Organization / Knowledge projections; SourceBoundSynthesisAdapter is properly treated as a KnowledgeProjection wrapper case.

B3. ✅ closed — ABC §7.7 numbering is corrected from “six-step” to “12-step / Steps 0–11.”

B4. ✅ closed — Skeletal §11.1–§11.13 are coherent as Stage 5R2b fold-ins: recovery/replay, consistency, EpisodePolicyEpoch re-gate, enforcement points, bitemporal axes, monotonicity, projection narrowing, DOC85 two-phase, and Library ADQ-202 gating all fit the family without reversing decisions.

B5. ✅ closed — OPA-035 correctly frames the SourceBoundSynthesisAdapter as a convergence seam, not a permanent destination; permanent unblessed wrapper activation is treated as a code smell.

B6. ✅ closed — DR-007 and DR-008 correctly mirror the DR-002 pattern: artifact pointers are present, and matrix-row additions are deferred to the next authorized matrix update.

B7. ✅ closed — Premise alias expiry now cross-references the §3 expiry table with owner-of-record / expiry condition.

B8. ✅ closed — Import Graph §5.1 footnote covers the listed supersession-matrix gaps and names the deferred lint `supersession.import_graph_object_without_matrix_row`.

B9. ✅ closed — No Stage 5R2b item changes the 8-member family, lockstep mapping, ADQ-220/221/222, ABC §7.8 enum, DOC88 declined status, or other architect adjudication.

## Concerns beyond the exit check

I would **not** start Stage 6 charters until the following tiny cleanup patch lands:

1. **Fix remaining compound owner:** change `ApprovedSafeLabelVocabularyRegistry | PropA / EC` into one owner plus executor/consumer semantics. My likely default: `ApprovedSafeLabelVocabularyRegistry` owned by **PropA**, EC executes/serves compiled registry; or owned by **EC** with PropA as semantic source. Pick one.
2. **Remove DOC8 runtime residue:** remove `DOC8 execute` from `MemoryFlowCertificate`; DOC8 should remain lineage/capability-mining only unless re-adopted.
3. **Clean stale skeletal prose:** update skeletal §3.2 “BDSM / DOC8 dependency_status pending ADQ-221” to reflect resolved ADQ-221: BDSM partial; DOC8 capability-mining only.
4. **Clean stale pending-disposition paragraph:** update skeletal §4.6 to match §10.8 / Owner Map / Conflict Register: VersionedClaim is DOC73 legacy + DOC82 lineage table; WorkSession is retained as light DOC83 temporal grouping unless Stage 6 later retires it.

After those four line-level fixes, I would mark the regression clean and allow **Stage 6 slice charters to begin**.





# CLAUDE:





# Stage 5R2 + Stage 5R2b Regression Review — Response

**Reviewer:** Claude (regression-check mode)
**Date:** 2026-05-28
**Prompt:** `Stage_5R2_Regression_Review_Prompt.md` (Stage 5R2 synthesis §9 exit-check + Stage 5R2b audit-gap fold-ins)
**Verification basis:** Direct read of all 11 patched artifacts via Filesystem connector (no reliance on the Patch Summary or Self-Audit's own ✅ claims).

---

## Summary

**All 22 exit-check items return ✅. Stage 6 slice charters may begin.**

The Stage 5R2 + Stage 5R2b patch set lands cleanly. Verified directly: the OP-A retargets reconcile against the 8-member ownership; the Owner Map passes its own `owner_map.compound_schema_owner` lint with §11 + §12 reconciliation notes; the Import Graph's 4-edge-kind restructure dissolves the phantom DOC82↔DOC83 cycle; SM-202's 7-value ABC §7.8 enum is verbatim against source; the §11.1–§11.13 architectural notes are coherent with the rest of the family; the two renames cascade consistently across all six artifacts where they appear; the DR-007/DR-008 entries mirror the DR-002 pattern exactly; the matrix-coverage-gap footnote in Import Graph §5.1 covers all four objects named in the prompt.

No new architectural reversal. The 8-member family, lockstep mapping, ADQ-220/221/222 resolutions, and ABC §7.8 enum are all preserved.

## Question A — Stage 5R2 synthesis §9 exit check

A1. ✅ **OP-A staleness resolved.** OPA-001 reconciled (Assertion schema → DOC82; DOC72 stores; EC writes); OPA-004 reconciled (EvidenceRecord/Edge → DOC82; DOC73 supplies); OPA-005 reconciled (DOC83 spine + DOC82 resolution; DAMS substrate in DOC84); OPA-011 reconciled (DOC85 not legacy DOC8); OPA-012 reconciled (DOC85 architecture; BDSM partial; DOC8 capability-mining only); OPA-031–034 added as named (`OP_A_Candidate_Disposition.md` rows OPA-001/004/005/011/012/031/032/033/034). Anti-staleness lints named in closing note.

A2. ✅ **Owner Map one-owner violations resolved.** 6 compound rows split atomically (`DOC80_Owner_Map.md` §2 LibrarySourceBinding + LibrarySourceBindingConsumptionContract; §3 SafeLabelDisclosurePolicy / ApprovedSafeLabelVocabularyRegistry / SafeLabelRenderContract; §5 RenderBundle / PromptTextPackage / DOC84RenderConsumptionContract; §1 ProceduralTaxonomy / SkillLifecycle / ProcedureExtractionRoute; §6 FalseSuppressionSampling / DAMSFalseSuppressionGuardrail; §3 contamination_risk threshold rule / contamination_risk computation). 2 placeholders resolved (§1 VersionedClaim → DOC73 + lineage table at DOC82, DR-003 closed; §5 DynamicHeaderLedger → DOC84, DR-004 closed). DAMS reframed as DOC84 substrate sections; DOC8 runtime-owner language purged; EC marked `partial / moving`. §11 + §12 reconciliation notes present.

A3. ✅ **Import-graph edge-kind ambiguity resolved.** `DOC80_Import_Graph.md` §2 restructured into 4 typed tables (§2.1 `schema_import`; §2.2 `runtime_instance_flow`; §2.3 `command_or_control_flow`; §2.4 `storage_or_execution_flow`). DOC82↔DOC83 phantom cycle dissolved — was mis-typed `schema_import`, correctly typed `runtime_instance_flow` in §2.2. §2.5 walks acyclicity with explicit topological order `DOC80 < DOC81 < DOC82 < DOC87 < DOC83 < DOC84 < {DOC85, DOC86}`. DOC87 verified all `schema_import` edges owner→consumer (inbound from DOC80/DOC81/DOC82, outbound to DOC83/DOC84/DOC86).

A4. ✅ **DOC83 → DOC87 TopicIdentityContract stub landed.** Plan §12.4-bis names the stub requirement verbatim (`MembershipTargetRef + OrganizationContainerRef + TopicRef + LibraryRef + ProjectMembershipRef` MUST land before DOC83's TopicCollectionDirective is drafted). Cross-referenced at skeletal §10.10 (`DOC80_Skeletal_Target_Baseline.md`) and OPA-032.

A5. ✅ **DOC8-as-runtime language purged.** Owner Map §6 row "Learning targets enum" + "Final-prompt-proof-gated utility" rows show "DOC8 references purged per synthesis #5"; DOC8 row in §9 reads "external — **capability-mining only**." Skeletal §5 (DOC85 section) and §10.18 ADQ-221 sweep tighten the language. OPA-011/012 rewritten. Lints named: `doc85.runtime_dependency_on_legacy_doc8`, `doc85.learning_computation_owned_by_phantom_doc8`.

A6. ✅ **DOC82 ↔ DOC83 disposition / resolution seam stated explicitly.** Skeletal §10.7 states the seam without relocating the enum: DOC83 owns extraction triage + recommended disposition (ABC §7.8 7-value enum stays at DOC83); DOC82 owns AssertionCandidate / AssertionResolution / AssertionDedupeOutcome + ABC §7.8 anti-overlap rule. Lints `assertion.overlapping_resolution_disposition_enum`, `assertion.doc83_final_resolution_without_doc82`, `assertion.doc82_resolution_missing_doc83_emission_ref` named.

A7. ✅ **SM-202 / DR-006 corrected from actual ABC §7.8 source.** Conflict Register DR-006 re-opened at Stage 5R2 with verified 7-value enum verbatim: `durable_eligible / durable_eligible_confirmation_required / session_scoped / ephemeral_reroute / candidate_only_pending_issueframe / review_queue / reject_not_memory`. Supersession Matrix SM-202 row carries the same enum plus separate `AssertionDedupeOutcome` axes (outcome ∈ {merge_to_existing_variant, add_variant_to_existing_assertion, create_new_assertion, reroute_misclassified}; dedupe_basis ∈ {source_span_duplicate, canonical_question_match, semantic_equivalence, authority_citation_match, manual_user_merge, no_match}). Retired Names row 19 (SM-202) consistent. Stage 5R2 process-discipline lesson recorded ("verified consistent" verifications must enumerate actual values, not just structural shape).

A8. ✅ **VersionedClaim + WorkSession resolved.** DR-003 closed in Conflict Register (VersionedClaim → DOC73 retains; DOC82 defines lineage table); Owner Map §1 row + skeletal §10.8 carry charter requirements. DR-005 disposition recorded (WorkSession → DOC83 working-state); Owner Map §4 row assigned to DOC83 with skeletal §10.8 disposition note. Lints `versioned_claim.unmapped_to_assertion_variant`, `versioned_claim.lineage_table_missing`, `worksession.disposition_unresolved_at_doc83_charter` named.

A9. ✅ **EC partial/moving + ECSeamContract.** Owner Map §9 row "EC | external — `dependency_status = partial / moving` (Stage 5R2 ECSeamContract per synthesis #9)". Skeletal §10.9 names the contract. OPA-031 fully specifies obligations (durable Assertion writes, durable membership writes, policy enforcement, learning write-back, command execution, source-revocation execution, audit + replay, compare-and-swap concurrency revalidation via `dedupe_basis_generation_id`, policy-generation re-gating). Lints `ec.*` family + `proof.durable_write_by_non_ec_actor` named.

A10. ✅ **Cross-artifact drift reconciled.** (a) Plan file `Flatten_and_Unify_Plan_V2_1c.md` §12.4-bis added between §12.4 and §12.5 ("Organization and membership slice (E_org)") with full slice scope + TopicIdentityContract stub requirement + ordering note. §12.5 E9 description rescoped per Patch B6 / ADQ-221. (b) ADQ-221 status drift swept at skeletal §10.18 + Owner Map §6 + Owner Map §9 (BDSM `partial`, DOC8 capability-mining-only). (c) Standing cross-artifact drift discipline at skeletal §10.19 with explicit closing-step rule for future patch rounds.

A11. ✅ **ADQ-222 opened.** `Architect_Decision_Queue.md` open-decisions section carries ADQ-222 (network/sharing forward-compatibility); tier = `batch_for_architect`; `default_if_no_response` blank per plan §11.4; gates Stage 7 schema-body work IF architect resolves "draft Phase-1 schemas now"; OPA-034 is the tracked seam.

A12. ✅ **DOC80-core non-goal + manual-deletion sentences present.** Skeletal §10.1 carries the V5 non-goal sentence verbatim (local-first, single-principal, single-node, single-EC-writer; multi-device sync / cross-user memory / mobile sync / shared Project writes / remote write authority out of scope; but durable objects carry stable IDs / generation refs sufficient for future replay). Skeletal §10.2 carries the manual-deletion sentence verbatim (EC can delete on request; unreachability is self-limiting; hard destruction is manually-driven append-an-event; no automated destruction-cascade machinery in V5; degradation default per architect adjudication).

A13. ✅ **DOC81 LegalHoldState flag + invariant in place.** Skeletal §10.3 declares `LegalHoldState` (`{held, not_held}` with scope) and the family-wide invariant that every automated destructive job MUST check and skip held objects. OPA-033 wires DOC72 §42 / DOC23 / DOC25 destructive-job amendments. Lints `legal_hold.destructive_job_skipped_check`, `revocation.support_edge_survives_revoked_source` named.

---

## Question B — Stage 5R2b audit-gap fold-ins

B1. ✅ **Renames applied consistently with clearer semantics.** `NonAssertionExtractionOutcome` → `AlternativeExtractionRouting` cascades through Owner Map §4 (active row), Import Graph §2.1 + §5.1, OP-A OPA-035 + closing note, ADQ-219 text, Conflict Register DR-007, Retired Names row 24 (lineage-only entry, not a Supersession Matrix row). `SourceBoundSynthesisProjection` → `SourceBoundSynthesisAdapter` cascades through Owner Map §1 (active row + KnowledgeProjection row), Import Graph §2.1 + §3 + §5.1 known-risk, OP-A OPA-035, ADQ-219 text, Retired Names row 25 (lineage-only). Skeletal §11.11 has the rename table with rationales. Semantically clearer: "routing" reflects DOC83's routing-layer role (vs the negation-named "outcome" that overloaded with ABC §7.5 `ExtractionOutputKind`); "adapter" reflects the compat-shim role at the DOC73→DOC82 seam (vs "projection" that overloaded with the SemanticProjection family).

B2. ✅ **SemanticProjection narrowed correctly.** Owner Map §8 has `SemanticProjectionContract` at DOC80 core (umbrella). Owner Map §5 has four narrowed projection rows with single owners: `DeliveryProjection + DeliveryProjectionInvalidationPolicy` (DOC84); `UIProjection + UIProjectionInvalidationPolicy` (DOC86); `OrganizationProjection + OrganizationProjectionInvalidationPolicy` (DOC87); `KnowledgeProjection + KnowledgeProjectionInvalidationPolicy` (DOC82). Each carries its own InvalidationPolicy. `SourceBoundSynthesisAdapter` correctly classified under `KnowledgeProjection` wrapper case in Owner Map §1 + skeletal §11.10. Skeletal §11.10 names the invariants (projection never owns truth; must carry source refs, generation id, invalidation policy, projection owner, proof/read-model refs) + 4 lints.

B3. ✅ **"Six-step" → "12-step (Steps 0–11)" corrected.** Skeletal §1.6 (DOC83 section) reads "ABC §7.7 12-step (Steps 0–11) normative classification decision tree" with the Stage 5R2b correction note verbatim. Owner Map §4 row 105 reads "ABC §7.7 12-step (Steps 0–11) extraction triage" with Stage 5R2b correction note. Skeletal §3.3 (ABC senior scoping note) is the Stage 5R2b senior-scoping fold-in that establishes WHY ABC §7.7 is senior (semantics seniority); it provides the authorization basis for the numbering correction rather than literally containing the step-count string — this is consistent with the patch summary's "Also reflected in §3.3 ABC senior scoping note" since "Six-step" never appeared in §3.3 in the first place. The replacement landed everywhere "Six-step" actually appeared.

B4. ✅ **§11.1–§11.13 architectural notes coherent.** All 13 sections present (`DOC80_Skeletal_Target_Baseline.md` §11.1 recovery/replay seam with replay-completeness invariant; §11.2 consistency model with single-node / single-EC-writer / V5 non-goal cross-ref; §11.3 EpisodePolicyEpoch extraction-side re-gate complementing OPA-031's resolution-side rule; §11.4 invariant-enforcement-point naming table with 7 named invariants + owners + lints; §11.5 DOC15 import seam check; §11.6 DOC26 citation check per F4 correction; §11.7 SourceBoundSynthesisAdapter convergence obligation cross-referencing OPA-035; §11.8 bitemporal axes `valid_time` + `transaction_time` on Assertion — Will-approved 2026-05-27; §11.9 monotonicity laws across membership / policy / source revocation / learning + injection-eligibility totality; §11.10 SemanticProjection narrowing anchor; §11.11 renames table; §11.12 DOC85 two-phase charter; §11.13 Library ADQ-202 gating). Non-contradictory with the rest of the family — consistency model aligns with V5 non-goal at §10.1; monotonicity laws align with ABC §7.13 warrant-degradation triggers; bitemporal axes refine §10.5 MemoryMutationEnvelope; renames table coheres with Retired Names entries 24-25.

B5. ✅ **OPA-035 SourceBoundSynthesisAdapter convergence obligation correct.** Text states verbatim: "Permanent unblessed wrapper activation is a `code_smell`, not a stable design: the adapter is a transition seam, not a destination." Cross-refs ADQ-219 (CU/DOC73 alignment) and Import Graph §5.1 known-risk. Lints `adapter.activated_without_convergence_plan`, `adapter.permanent_activation_without_architect_blessing`, `cu_doc73.divergence_unresolved_after_charter` named. The convergence path is bounded: DOC73 converges within a stated charter window OR architect blesses permanent divergence via new ADQ. Escalation to `architect_stop` named if adapter cannot cleanly absorb.

B6. ✅ **DR-007 + DR-008 mirror DR-002 pattern correctly.** DR-007 (`AlternativeExtractionRouting` matrix-row gap) and DR-008 (`AssertionCandidateEmission` matrix-row gap) both follow the DR-002 template: source_refs name the affected artifacts; disagreement_kind = `supersession_disposition` (matrix gap); proposed_resolution mirrors DR-002 with artifact pointer (Owner Map row + Import Graph §5.1 footnote) + matrix-row addition deferred to next authorized matrix update; architect_required = no; status = resolved (artifacts patched; matrix-row addition is an authorized future matrix update). Both opened and resolved in the same session per the DR-002 pattern.

B7. ✅ **Premise alias_expiry cross-ref present.** `DOC80_Retired_Names.md` §1 row 3 (Premise as memory object) `legacy_alias_allowed` column reads: "yes (until cross-doc rename pass — see §3 alias-expiry table for owner-of-record and expiry condition)". §3 carries the Premise row with rename pass owner "DOC80 family + DOC72 + DOC73" and expiry condition "until cross-doc rename pass complete."

B8. ✅ **Import Graph §5.1 footnote covers all four matrix-coverage gaps.** `DOC80_Import_Graph.md` §5.1 Stage 5R2b footnote table contains: `LibrarySourceBinding / CorpusIndex / SourceCollection` (decomposed Library/Corpus, DR-002); `VersionedClaim` + `VersionedClaim → AssertionVariant` lineage table (DR-003, closed at Stage 5R2); `AssertionCandidateEmission` (DR-008, added at Stage 5R2b); `AlternativeExtractionRouting` (DR-007, added at Stage 5R2b). Deferred lint `supersession.import_graph_object_without_matrix_row` named with Stage 9 deferral. Footnote also notes the Extraction trio (`ExtractionContextPlan / ExtractionRouteContext / ExtractionResult`) is partially covered and queued for the same matrix update.

B9. ✅ **No new architectural reversal.** Stage 5R2b additions preserve everything: 8-member family DOC80–DOC87 unchanged; lockstep mapping E1+E2→DOC81, E3+E4→DOC82, E7+E8→DOC84 unchanged; ADQ-220 (DOC87 creation), ADQ-221 (BDSM partial / DOC8 capability-mining only), ADQ-222 (network/sharing forward-compatibility) all unchanged; ABC §7.8 7-value `AssertionCandidateDisposition` enum + separate `AssertionDedupeOutcome` unchanged; DOC88 declined status unchanged; DR-001 through DR-006 dispositions unchanged (rename references updated but resolutions untouched); architect adjudications on degradation-default / legal-hold-as-freeze / network-sharing unchanged. Stage 5R2b Self-Audit's "What Stage 5R2b does NOT change" section enumerates the same preservation set.

## Gate

All 22 items return ✅. **Stage 6 slice charters may begin.**

Per the prompt's gate condition, the Stage 5R2 synthesis §9 exit-check items are closed (Question A) AND the Stage 5R2b audit-gap fold-ins are sound (Question B). No `❌` or `⚠️` raised; no concerns beyond the exit check that warrant a separate section.
