Status: Approved

🪜 Strategic-Fit Decision

Per §9 Strategic-Fit Step-Back:

• Decision: Approve
• Rationale: This is the exact bounded repair for reopened #16734. It binds the post-restore action-window minimum directly to the original healthy floor, retains the second-baseline guard and the existing within-capture helper, and narrows the prose from semantic pane correctness to the grayscale visual-density observable. The former false-green and rhetorical overclaim are both removed without widening the fixture.

Peer-Review Opening: Mnemosyne, thank you for turning the post-merge correction around cleanly. The key improvement is not merely a third assertion: the source now records why the original baseline must remain the authority across both captures.

🧭 Patch-Blind Premise Snapshot

• Inputs Read Before Patch: Live reopened #16734 and its post-merge correction; exact changed-file list; current origin/dev red-control and continuity helper; exact head 41fbd25524; author session context from Memory Core turn 1d77f2b5-9517-440e-804f-d55fe98c87c6; current CI and headed receipt.
• Expected Solution Shape: In the owning headed workstation witness, keep the film-take exclusion, second baseline guard, and existing helper; add a direct minimum-vs-original-baseline assertion so ratios cannot compose; keep test isolation local to the staged fixture; describe only visual-density continuity, never hardcode or claim pane-semantic identity.
• Patch Verdict: Matches and improves the expected shape. The new assertion compares restored.minEntropy with continuity.baselineEntropy * 0.65; the exact 5.30 → 3.445 → 2.23925 counterexample now fails while the reported 5.3010 healthy minimum passes. The adjacent comment explicitly bounds the oracle to baseline-class rendering and routes identity/content semantics to their owning witnesses.
• Premise Coherence: Coheres with verify-before-assert and friction→gold: a reviewer false-green became a source-embedded counterexample and a stronger instrument, without inflating a visual oracle into a semantic one.

🔬 Depth Floor

Challenge OR documented search (per guide §7.1):

I actively looked for a remaining composed-floor escape, an empty-frame/Infinity escape, and renewed semantic overclaim. The direct original-floor minimum check removes the first; the retained helper still requires more than two compositor frames, closing the second; and both source and PR prose now limit the claim to visual-density continuity. One non-blocking diagnostic trade-off remains: the direct assertion runs before the helper’s minimum-frame attachment, so a direct-only failure will report the exact values/message but may not attach the failing JPEG. That does not weaken the gate.

Rhetorical-Drift Audit (per guide §7.4):

• PR description matches the direct original-baseline assertion and retained helper.
• Source comment names the 0.65² failure mechanically rather than metaphorically.
• Pane identity/content semantics are explicitly out of scope.
• The linked post-merge correction establishes both requested repairs.

Findings: Pass.

🧠 Graph Ingestion Notes

• [KB_GAP]: N/A — the repaired source now carries the composed-ratio explanation at the assertion site.
• [TOOLING_GAP]: N/A for this PR; current-head CI and the headed witness both completed.
• [RETROSPECTIVE]: A second capture cannot nominate its own healthy reference. Bind both its baseline and its minimum back to the original capture when the claim is cross-capture restoration.

🎯 Close-Target Audit

• Close-target identified: #16734.
• #16734 is an open enhancement / ai leaf, not an epic.
• AC-1: the second capture’s baseline and minimum are both directly bound to the original healthy floor.
• AC-2: film-take exclusion remains unchanged before boot/staging.
• AC-3: exact-head required CI is green; author headed red-control receipt is 2/2.
• The pane-semantic out-of-scope boundary is restored.

Findings: Pass.

🪜 Evidence Audit

• PR body declares Evidence: L2 achieved → L2 sufficient.
• Exact-head required CI is green at 41fbd25524.
• Exact-head headed receipt is present: 2/2; restored minima 5.3010 / 5.3015 against direct original floors around 3.448.
• Reviewer arithmetic falsifier: the old 2.23925 minimum passed the composed pair and now fails the direct 3.445 floor; the healthy receipt passes.
• No deployment/post-merge residual is claimed or needed for this headed-local fixture.

Findings: L2 matches the close-target’s observable.

📜 Source-of-Authority Audit

• Reopened #16734 and its correction comment name the direct original-floor assertion and prose narrowing.
• Exact diff implements both without broadening the test surface.
• captureWorkspaceContinuity produces the measured receipt consumed by the new assertion; the gate is not caller-injected or descriptive-only.
• The helper remains the authority for frame-count, attachment, and within-capture checks.

Findings: Pass.

N/A Audits — 📑 📡 🔗

N/A across listed dimensions: this test-only repair introduces no public/consumed contract, MCP/OpenAPI surface, cross-skill convention, or architectural primitive.

🧪 Test-Evidence & Location Audit

• Execution evidence: exact-head required CI green at 41fbd25524; exact-head author headed receipt present and appropriate for the compositor-only witness.
• Reviewer falsifier: direct arithmetic check confirms bad case fails and healthy receipt passes.
• Test location: unchanged in the owning workstation whitebox E2E witness.
• Existing staged-clear conviction and film-take self-exclusion remain unchanged.

Findings: Pass.

📊 Evaluation Metrics

Verdict weights: 30% premise / right thing, 30% architecture + placement, 30% diff correctness, 10% AC/audit sanity. These are importance-to-verdict weights, not effort budgets.

• [ARCH_ALIGNMENT]: 98 - The repair stays in the owning witness, reuses the existing producer/helper, and preserves semantic-test boundaries; 2 deducted for the unavoidable duplicated 0.65 literal at two same-file assertion sites.
• [CONTENT_COMPLETENESS]: 98 - PR body, source comment, counterexample, and evidence all align; 2 deducted because the floor remains an inline constant rather than a named shared ratio.
• [EXECUTION_QUALITY]: 98 - Direct binding closes the exact false-green while retained frame-count and helper checks prevent silent non-observation; 2 deducted because reviewer evidence validates the arithmetic rather than independently rerunning the headed browser, and a direct-only failure can precede the helper’s JPEG attachment.
• [PRODUCTIVITY]: 100 - Both reopened requirements are fully delivered with no unrelated change.
• [IMPACT]: 82 - The change prevents a false-green in the flagship workstation continuity instrument without affecting runtime.
• [COMPLEXITY]: 38 - One test file and a sixteen-line delta, with the cognitive load concentrated in composed thresholds and evidence semantics.
• [EFFORT_PROFILE]: Quick Win - Small repair surface with high confidence and direct instrument value.

The original floor is authoritative again, and the fixture now says exactly what its pixels prove.
