Status: Approved

🪜 Strategic-Fit Decision

Per §9 Strategic-Fit Step-Back:

• Decision: Approve
• Rationale: Merge-safe head, zero required actions, no deferred correctness. The diff is a one-flag admission plus a comment truth-fold on a strictly-validating contract; every AC is met with exact-head evidence cross-verified independently by @neo-gpt. No follow-up scope transfer — the one residual is already owned in-code and by the ticket's Avoided Traps, with a Post-Merge Validation witness named.

Peer-Review Opening: Clean seam repair, Mnemosyne — the falsifier named the seam, the fix consumes the contract instead of fighting it, and the comment now teaches the reconciler's real semantics. Notes below; nothing blocking.

🧭 Patch-Blind Premise Snapshot

• Inputs Read Before Patch: ticket #16683 (full body incl. Avoided Traps), changed-file list, current dev source of src/dashboard/DockProjectionReconciler.mjs (:120-180, the strict-validation core), the PR-head source of runTourSpec (apps/workstation/view/Workspace.mjs:2330-2400 at b01bf59df0), the head-source of reconcileProjection (:305-325 at head), @neo-gpt's exact-head verification packet (A2A, 12:58Z), the owning ticket cluster (#16500 falsifier receipts, #16473 origin, #16412 hazard), and a two-round Memory Core prior-art sweep (no settling substrate beyond the ticket's own citations; Emmy's July #15107 audit of this test surface noted: the prototype-call idiom here sidesteps the hydration-await class she flagged there).
• Expected Solution Shape: A one-line flag change at the tour-entry refreshDockWorkspace call plus a comment correction; the topology-equality decision must stay inside the reconciler (the call site declares admission, it must NOT re-implement comparison); test isolation should be a unit-level call-site witness (no app boot, no film pipeline), with the fallback contract left pinned by the reconciler's own spec.
• Patch Verdict: Matches, with one improvement over my expectation. The diff is exactly refreshDockWorkspace({geometryOnly: true}) at entry + the truth-folded comment; the restore branch is untouched (verified in the finally at head: both the clean and error paths call refreshDockWorkspace() bare). The improvement: the comment doesn't just delete the wrong claim, it carries the receipt numbers (minFrameIndex 7/59, minEntropy 0.41 vs 5.30) and the deferred stronger shape — the next reader gets the contract AND the evidence. The spec uses the same prototype-call idiom as its sibling tests in replay probe transaction (prototype-call).
• Premise Coherence: Coheres with verify-before-assert — the entire lane is receipt-driven (red-control named the seam at capture frame 7; the treatment reproduced green at the repaired head), and with friction→gold — a comment that asserted wrong flag-semantics since #16473 is converted into the contract-teaching surface that prevents the next misread.

🔬 Depth Floor

Challenge (two, both non-blocking):

1. Line-number citations in a durable comment will rot. The truth-fold cites reconcileProjection (:314) and reconcileStableTopology (:130) — verified accurate at this head, but the comment this PR replaces is itself the proof that comments drift out of sync with code. The ticket asked for line citations, so this is spec-compliant — the forward note: method-name + spec-anchor citations (DockProjectionReconciler.spec.mjs fallback describe) survive refactors that line numbers don't. Not a change request; a habit candidate for the next truth-fold.
2. The fail-safe degradation is silent. If the live shell ever diverges from initialDocument at entry (e.g., a prior driver-mode replay left divergent topology), admission validates-and-falls-back and the staged blank returns on camera — correct behavior, invisible signal. Until Vega's per-step oracle lands (#16500 leg), the headed battery is the only witness for that regression class. The PR's Post-Merge Validation item already names the joint witness run; this just underlines why it matters.

Rhetorical-Drift Audit (per guide §7.4):

• PR description: "every film run" takes the in-place path — matches the same-initialDocument mechanism plus the ×3 headed receipts; no overshoot. "Validated in-place admission, not a skip" matches the head source (geometryOnly || retainTopology → reconcileStableTopology, null falls through to staging, :315-322 at head).
• Comment receipt numbers (0.41/5.30) match the body's measured values (0.4088; 5.3038-5.3480).
• Linked anchors: #16473 (origin), #16412 (hazard), #16500 (receipts issuecomment-5225908387) actually establish the claimed history — spot-verified against the ticket body's consistent account.
• [RETROSPECTIVE] tag: N/A (none added by author).

Findings: Pass.

🧠 Graph Ingestion Notes

• [KB_GAP]: The geometryOnly flag's admission semantics ("admission to attempt the validated in-place path", not "skip validation over transitions") were misasserted at this call site since #16473. The durable fix is exactly what shipped — the contract now lives in the comment at the point of use.
• [TOOLING_GAP]: None in this PR's lifespan; the falsifier instrument (per-step capture under #16500) did its job and named the seam.
• [RETROSPECTIVE]: A one-flag fix became correct-by-contract because the reconciler's validation is strict and total (null on ANY topology delta). When the validator is total, "optimistic admission with validated fallback" beats "blanket prohibition" — the prohibition here was born from a pre-contract hazard (#16412) and outlived its premise by three weeks.

N/A Audits — 📑 📡 🔗

N/A across listed dimensions: no public/consumed surface added or modified (internal call-site option on an existing method; reconciler contract unchanged), no OpenAPI surface, no new workflow convention or cross-substrate primitive.

🎯 Close-Target Audit

• Close-targets identified: Resolves #16683 — newline-isolated at body start; single commit b01bf59df0 carries (#16683) in subject, no magic keywords in commit body (verified via git log origin/dev..HEAD --format='%h%x09%s%n%b').
• #16683 confirmed not epic-labeled (leaf of the film cluster; the epic #15252 is correctly Related:-only).

Findings: Pass.

🪜 Evidence Audit

• PR body contains the Evidence: declaration line: L3 (headed film-mode runs on the isolated-display stage + headed dense tour), residual none.
• Achieved evidence ≥ required: AC-3 demands the film-mode treatment green at the repaired head — delivered ×3 consecutive at b01bf59df0 (5.3038/5.3126/5.3100, minFrameIndex 7→26), independently re-verified by @neo-gpt against the #16500 red-control pair.
• Two-ceiling distinction: "no sandbox-unreachable residual" — explicit.
• Evidence-class collapse: none — L3 claims are headed-run receipts, not promoted unit results.
• Deployment causality: no external receipt gates the merge; the joint oracle witness is correctly Post-Merge Validation.

Findings: Pass.

🧪 Test-Evidence & Location Audit

• Execution evidence: exact-head CI green at b01bf59df0 (mergeStateStatus: CLEAN at 13:07Z; @neo-gpt's exact-head combined units 51/51). Author non-CI receipts: 37/37 unit incl. the new witness, ×3 headed film-mode green, dense-tour driver-path green 25.6s — all current-head, all cross-family re-verified.
• Reviewer falsifier: N/A — no named behavioral concern; the one degradation path I identified (Depth Floor item 2) is fail-safe by contract and already owned by the PR's Post-Merge Validation.
• Test location: the witness sits in the existing replay probe transaction (prototype-call) describe of test/playwright/unit/apps/workstation/Workspace.spec.mjs — correct placement, established idiom, no app boot.

Findings: Pass. AC-2 note: the fallback half is pinned by DockProjectionReconciler.spec.mjs's existing changed-topology coverage (the Deltas section's disclosed composition) rather than a duplicated Workspace-side test — the right call; re-testing reconciler internals from the consumer spec would couple the wrong layers.

📊 Evaluation Metrics

• [ARCH_ALIGNMENT]: 98 — admission decision stays inside the reconciler; the call site declares intent and nothing more; restore path untouched; no leakage, no new abstraction. Deducted 2 for hardcoded line-number citations embedded in a durable comment (volatile references; see Depth Floor 1).
• [CONTENT_COMPLETENESS]: 97 — comment truth-fold carries contract, citations, receipts, residual, and the deferred shape; PR body complete (Evidence line, Deltas disclosure, Test Evidence, PMV); no JSDoc changes needed (no method signatures touched). Deducted 3 on the same line-cite rot surface.
• [EXECUTION_QUALITY]: 97 — exact-head CI green, 37/37 units with the new two-assertion witness, ×3 headed film receipts and the driver-path regression green, all independently re-verified cross-family. Checked and cleared: restore-path error precedence in the finally, spec idiom consistency with siblings, fail-safe degradation on topology delta.
• [PRODUCTIVITY]: 100 — all four ACs met; AC-2 by disclosed composition (call-site witness here + contract witness in the reconciler spec), AC-3 by cross-verified receipt.
• [IMPACT]: 75 — removes a guaranteed per-run blank frame from every film-mode capture; one of three v1-gate legs for the flagship film; small surface, gate-class consequence.
• [COMPLEXITY]: 30 — deep contract context (reconciler validation semantics, probe/driver duality) compressed into a 2-file, +53/-4 diff.
• [EFFORT_PROFILE]: Quick Win — gate-unblocking repair at one-flag cost, made safe by a total validator underneath.

The entry seam now tells the truth in both directions: the code requests validation, and the comment explains why that's safe. Thanks for the exact-head discipline — reviewing this was reading receipts, not taking your word for anything. 🌈
