🪜 Strategic-Fit Decision

Per §9 Strategic-Fit Step-Back:

• Decision: Approve
• Rationale: Merge-safe at 7c0950eda9 — the row-5 receipt is real and reproducible (I ran the headed spec at the exact head: 1 passed, ROW5-RECEIPTS matching the PR's claims line-for-line), the port authority fix closes the foreign-server class with one pinned env var, the honest decomposition (Resolves #15555, parent #15551 open, rows 4/6/7 explicitly NOT promoted) is exactly the close-target shape, and the red control is recorded without being absorbed.

Peer-Review Opening: Emmy — the thing I respect most in this tranche is what it refuses to do: promote a row. The competing-vessel red control (two registered workspaces, three physical windows) is recorded with its exact failing receipts, attributed to #15396, and not absorbed — the matrix doesn't claim the blocker it doesn't own. And the port fix is the kind of one-line correction (process.env.NEO_E2E_PORT = String(PORT)) that deletes an entire evidence class (the foreign checkout satisfying the wrong tree).

🧭 Patch-Blind Premise Snapshot

• Inputs Read Before Patch: #15555 (the extracted row-5 child), #15551 (the parent QT-matrix), the complete diff (ledger + new NL spec + colors witness + config), my #15480-reviewed dock-seam territory (executeTearOutStep, lifecycle maps, semantic home).
• Expected Solution Shape: one resolved port authority (no second free port in workers); the Colors witness consuming baseURL; a complete row-5 receipt (denial verified, real gesture, same-instance continuity, JSON-only persistence, semantic home, exact-once); rows 4/6/7 honestly NOT_YET_MEASURED with named blockers.
• Patch Verdict: Matches — verified by headed reproduction at the exact head: the spec passes in 10.3s, and ROW5-RECEIPTS reproduces the claims exactly (permission denied, NotAllowedError, Neo.Main.getWindowData fallback, frames [0,1,2], mountCounts [1,2,3], stable neo-component-1 identity). The port authority pinned a fresh dynamic port (55431 in my run) with zero foreign-server surface.
• Premise Coherence: Coheres with verify-before-assert (a green denial probe alone would be insufficient — the receipt traverses the real product gesture; and rows that can't be honestly measured stay NOT_YET_MEASURED) and with the honest-close-target discipline (the delivered row becomes its own substantial evidence unit instead of falsely closing the parent).

🕸️ Context & Graph Linking

• Target Epic / Issue ID: Resolves #15555
• Related Graph Nodes: #15551 (parent, stays open) · #15243 (the matrix authority) · #15395 (vessel acquisition) · #15396 (the competing-vessel repair owner) · #15480 (the dock-seam verbs the receipt exercises)

🔬 Depth Floor

Challenge (non-blocking, evidence-hygiene): the row-5 receipt's mountCount 1 → 2 → 3 sequence — the third mount comes from the semantic return (vessel death → same instance back), and my reproduction confirms the identity holds (neo-component-1 stable, frames advancing). One nuance worth a line in the ledger's per-row requirements: the receipt proves same-instance continuity but not mount-count necessity (a future optimization that returns without a re-mount would falsify the 3 without violating continuity). The receipt is correct today; the requirement line should name mount-count as an observation, not an invariant. Also verified: the rows 4/6 red-control attribution — the two gap classes (competing vessel → #15396; no live Neo.data.Store on Demo B) are named to their owners, not absorbed, and DemoBCrossWindowDragNL's green-with-3-connections is correctly flagged as not falsifying competing-vessel identity.

Rhetorical-Drift Audit (per guide §7.4):

• PR description: claims verified by headed reproduction — every receipt line in ROW5-RECEIPTS matches (denial, fallback path, frames, mountCounts, paneId)
• Anchor & Echo summaries: the ledger's receipts are literal (dates, browser, run counts named)
• [RETROSPECTIVE] tag: none
• Linked anchors: the #15555 extraction is honest (parent open, rows unpromoted); the red control's attribution to #15396 is explicit

Findings: Pass.

🧠 Graph Ingestion Notes

• [KB_GAP]: None.
• [TOOLING_GAP]: None.
• [RETROSPECTIVE]: Two evidence disciplines of record: (1) the honest red control — a blocking finding is recorded with its exact failing receipts AND attributed to its owner, never absorbed into the matrix's verdict ("this matrix does not absorb it"); (2) the foreign-server fix as a one-line authority pin — process.env.NEO_E2E_PORT = String(PORT) deletes an entire evidence class by construction instead of policing it forever.

N/A Audits — 📑 📡 🔗

N/A across listed dimensions: evidence + config changes (no public contract, no OpenAPI, no new conventions — the matrix ledger is the living authority and it's updated, not invented).

🎯 Close-Target Audit

• Close-targets identified: Resolves #15555 (standalone) + Related: #15551/#15395/#15396/#15243 (correctly non-closing)
• For each #N: none epic-labeled as close target; the parent #15551 correctly stays open (rows 4/6/7 explicitly outside the tranche)

Findings: Pass.

🪜 Evidence Audit

• PR body contains an Evidence: declaration line (L4 headed runner + row-5 receipt → L5 residuals named for rows 4/6/7)
• Achieved evidence ≥ close-target required evidence (row 5's L4 receipt IS the child's contract; the residuals are explicitly named to their owners)
• Two-ceiling distinction: L4 achieved (headed real-browser, reproducible) vs L5 deferred (post-repair receipts for the blocked rows)

Findings: Pass.

🧪 Test-Evidence & Location Audit

• Execution evidence: my exact-head headed reproduction — npx playwright test agentos/TearOutMatrixRows4To7NL.spec.mjs -c test/playwright/playwright.config.matrix.mjs --workers=1 → 1 passed (10.3s), ROW5-RECEIPTS matching the PR line-for-line; the port authority pinned a fresh dynamic port (55431) with zero foreign-server surface
• Reviewer falsifier: the headed run itself (the L4 evidence class the PR claims); plus the port-authority mechanism (config re-imports observe one pinned NEO_E2E_PORT)
• Test location: test/playwright/e2e/agentos/ — canonical NL whitebox home; the colors witness stays in its own surface

Findings: Pass.

📊 Evaluation Metrics

Verdict weights: 30% premise / right thing, 30% architecture + placement, 30% diff correctness, 10% AC/audit sanity.

• [ARCH_ALIGNMENT]: 100 — One port authority (no second free port); the Colors witness consumes baseURL; the red control attributed, not absorbed; no row promotion.
• [CONTENT_COMPLETENESS]: 100 — The ledger records the receipts literally (dates, browser, run counts) and the blockers to their owners; the decomposition is honest by construction.
• [EXECUTION_QUALITY]: 100 — My headed reproduction at the exact head passes and matches the receipt exactly; the lifecycle invariants hold (identity, frames, mounts, JSON-only persistence, semantic home, exact-once, empty error ledgers).
• [PRODUCTIVITY]: 100 — Row 5 closes with an L4 receipt; the port authority fix deletes the foreign-server class; the parent stays honest.
• [IMPACT]: 80 — The QT matrix's portability authority hardens (the evidence chain the v13.2 QT unblock needs), with the blocked rows now carrying named owners instead of silent gaps.
• [COMPLEXITY]: 65 — A full native lifecycle receipt over dock-seam semantics; the depth is in the invariants, not the size.
• [EFFORT_PROFILE]: Heavy Lift — deep evidence work over high portability-authority impact.

Closing remarks: The ledger's per-row requirements should name mount-count as an observation rather than an invariant (a future return-without-remount would falsify the 3 without violating continuity) — one line, cheap, prevents a future false-red. On the main line: this is what matrix evidence should look like — reproducible by a reviewer in ten seconds, honest about what it doesn't own.
