# Stage 5R2c — Regression Review Response (corrected)

**Date:** 2026-05-28
**Supersedes:** `Stage_5R2_Regression_Review_Responses.md` verdict only. The Stage 5R2 reviews themselves (ChatGPT, Claude 4.7) remain on file as the source-of-record review traffic. Claude 4.8 re-audit is incorporated.
**Patch reference:** `Stage_5R2c_Patch_Summary.md`.

## Verdict

**Stage 5R2 close decision (Stage 5R2c retrospective): NOT closed at Stage 5R2 / 5R2b. Now closed at Stage 5R2c following 13 line-level cleanup edits across 5 files.**

- ChatGPT regression review: VERIFIED correct — Stage 5R2 was not closed. All 4 ChatGPT findings cleared at Stage 5R2c.
- Claude 4.7 regression review: VERIFIED incomplete — although marked "All 22 ✅," it missed 9 additional residuals later caught by Claude 4.8 re-audit. All 9 cleared at Stage 5R2c.
- Claude 4.8 re-audit: VERIFIED — all 9 additional findings independently confirmed against live files (Owner Map, Skeletal Target Baseline, OP_A Candidate Disposition, Architect Decision Queue, Supersession Matrix) and cleared at Stage 5R2c.

Stage 6 charter authoring may now open.

## Why Stage 5R2 looked closed but wasn't

The Stage 5R2 sweeps applied substantive architecture-level corrections — DAMS V5 → DOC84-substrate reframe, DOC8 purge from runtime, DOC73 V1.6 CSA extraction, ADQ-220 8th-member addition, ECSeamContract introduction, etc. — but did not perform a final prose pass over all dependent rows. The residuals all followed one of three patterns:

1. **Owner-name reframe propagated to schemas but not to triggers / OP-A target_doc** (Owner Map line 171, OPA-019, ADQ-312).
2. **DOC8 purge propagated to learning rows but left residual mentions in execute-cells and trigger lists** (Owner Map lines 150 + 171, ADQ-312, Skeletal §1, §3.2, §4.5).
3. **Rename ledger entries (Stage 5R2b) propagated to the schema's primary location but not to cross-reference prose** (SM-202 `NonAssertionExtractionOutcome` → `AlternativeExtractionRouting`).

Plus two counter / status drift items:

4. **OPA-035 added at Stage 5R2b but header row count not bumped** (34 → 35).
5. **ADQ-310 resolved at Stage 4 gate but SM-213 status not propagated** (`unresolved` → `absorb_as_target_rule`).
6. **ADQ-220 added at Stage 5R but never counted in `architect_stop` tier total** (5 → 6, paired with 38 batch row total to recover the 44 advertised in header).

7. **One framing collision in ADQ-222 prose** between Stage-6-non-blocking and Stage-7-conditional-gating use of the word "blocking" — not architecturally wrong but visually contradictory.

All seven patterns are bookkeeping omissions, not architectural mistakes. The architecture-level decisions were sound; the prose sweep was incomplete.

## Per-reviewer outcome

### ChatGPT findings (4 — all cleared)

| # | finding | Stage 5R2c fix item |
|---|---|---|
| C1 | Owner Map line 88 `ApprovedSafeLabelVocabularyRegistry` compound owner | Item 1 |
| C2 | Owner Map line 150 `MemoryFlowCertificate` DOC8 residual in executes-cell | Item 2 |
| C3 | Skeletal §3.2 line 328 `BDSM / DOC8` phantom + pending ADQ-221 stale text | Item 4 |
| C4 | Skeletal §4.6 "Pending matrix-gap dispositions" block contradicting §10.8 resolutions | Item 7 |

### Claude 4.7 findings (22 — none re-opened; verdict revised from "closed" to "closed pending Stage 5R2c sweep")

Claude 4.7 marked all 22 of its own check items ✅. No items are re-opened. But the verdict ("Stage 6 may begin") was premature relative to ChatGPT's still-open findings and Claude 4.8's later additional findings. Stage 5R2c closes that gap.

### Claude 4.8 findings (9 — all cleared)

| # | finding | Stage 5R2c fix item |
|---|---|---|
| C4.8-1 | Owner Map line 171 Warrant-degradation-trigger registry — DOC8 residual | Item 3 (DOC8 portion) |
| C4.8-2 | Owner Map line 171 Warrant-degradation-trigger registry — DAMS V5 owner-name residual | Item 3 (DAMS V5 portion) |
| C4.8-3 | Skeletal §1 line 80 "Consumes BDSM (pending ADQ-221)" | Item 6 |
| C4.8-4 | Skeletal §4.5 line 390 `DOC8/BDSM (pending ADQ-221)` | Item 5 |
| C4.8-5 | OP_A Candidate Disposition header row count 34 vs 35 | Item 8 |
| C4.8-6 | OP_A Candidate Disposition OPA-019 target_doc `DAMS V5` | Item 9 |
| C4.8-7 | Architect Decision Queue `architect_stop: 5` should be 6; total 43 ≠ 44 | Item 10 |
| C4.8-8 | Architect Decision Queue ADQ-312 trigger owners (DOC8 + DAMS V5 residuals) | Item 11 |
| C4.8-9 | Architect Decision Queue ADQ-222 framing collision on "blocking" | Item 12 |

Bonus items not flagged by Claude 4.8 but caught by the rename-propagation discipline:

| # | finding | Stage 5R2c fix item |
|---|---|---|
| C4.8-extra-A | Supersession Matrix SM-202 stale `NonAssertionExtractionOutcome` schema name | Item 13 |
| C4.8-extra-B | Supersession Matrix SM-213 status still `unresolved` despite ADQ-310 closed | Item 14 |

## Confirmation that no architecture decision changed

| dimension | before Stage 5R2c | after Stage 5R2c |
|---|---|---|
| 8-family member count (DOC80–DOC87) | 8 | 8 (unchanged) |
| ADQ row total | 44 (43 resolved + 1 open) | 44 (43 resolved + 1 open) (unchanged) |
| OP-A candidate row total | 35 (header stale at 34) | 35 (header corrected) |
| SM row total | 49 | 49 (unchanged; SM-213 update is in-row, not row add) |
| Owner-cell semantics | mix of stale + current | uniformly current |
| Tier counts | 5 architect_stop + 38 batch_for_architect = 43 (≠ 44) | 6 architect_stop + 38 batch_for_architect = 44 ✓ |
| Open seams | ADQ-222 + OPA-024 + OPA-035 + DOC85 E9 two-phase | same — Stage 6 charter-window work, not Stage 6 entry blockers |

## Files changed at Stage 5R2c

- `Memory Rebuild Docs/DOC80 Target Baseline/Owner Map/DOC80_Owner_Map.md` (lines 88, 150, 171)
- `Memory Rebuild Docs/DOC80 Target Baseline/Skeletal Spec/DOC80_Skeletal_Target_Baseline.md` (lines 80, 328, 390, §4.6 block)
- `Memory Rebuild Docs/Flattening/Execution Ledger/OP-A Disposition/OP_A_Candidate_Disposition.md` (header, OPA-019)
- `Memory Rebuild Docs/Flattening/Execution Ledger/Architect Decision Queue/Architect_Decision_Queue.md` (header tier counts, ADQ-222 status-distribution paragraph, ADQ-312 row)
- `Memory Rebuild Docs/Flattening/Supersession Matrix/Supersession_Matrix.md` (SM-202, SM-213)
- `Memory Rebuild Docs/Flattening/Execution Ledger/Stage_5R3/baseline_snapshot/DOC80_Owner_Map.md` (refresh; sha256 461d138404b8)
- `Memory Rebuild Docs/Flattening/Execution Ledger/Stage_5R3/baseline_snapshot/DOC80_Skeletal_Target_Baseline.md` (refresh; sha256 3976b29a69da)

## Stage 5R3 audit implication

Stage 5R3 Pass 0 source package pinned the pre-Stage-5R2c hashes for DOC80_Owner_Map.md and DOC80_Skeletal_Target_Baseline.md. After Stage 5R2c, those two source pins are stale.

Pass 0 source package needs a one-line update:

- `DOC80_Owner_Map.md` sha256(12) old → `461d138404b8` (new live + new snapshot)
- `DOC80_Skeletal_Target_Baseline.md` sha256(12) old → `3976b29a69da` (new live + new snapshot)

The Stage 5R3 Pass 1 deliverables (PASS_1_*.md) do not need re-running. Their analysis was over OP-A V3.18 + MSL + the DOC80 baseline structurally — the structural content is unchanged; only stale prose was corrected.

Pass 2 (Claude Code retargeting) is unaffected. The 13 fixes here are independent of the Pass 1 architect-decision resolutions.

## Next action

1. Will reviews `Stage_5R2c_Patch_Summary.md` and this file.
2. If ratified: open Stage 6 charter authoring per `Flatten_and_Unify_Plan_V2_1c.md` §12 / §18.
3. Stage 5R3 Pass 0 source package: bump the two DOC80 baseline-file hashes to the post-5R2c values noted above.
4. Stage 5R3 Pass 2 commission can proceed in Claude Code with no scope change.
