Resolves #15426

Related: #15243 — which stays OPEN owning the complete 7×3 matrix + revalidation gate, per the contract author's authority ruling (A2A 2b007108): this PR delivers the narrow FOUNDATION leaf (runner + living evidence ledger + qualified macOS probes), never the completed contract. Remaining rows/columns land as #15243 children updating the one ledger.

The tear-out portability matrix's foundation: the living EVIDENCE LEDGER (learn/guides/specificfeatures/TearOutPortabilityMatrix.md — self-described subordinate to ADR 0029 + the open #15243 authority, registered hidden in learn/tree.json), the spike-owned headed runner (test/playwright/playwright.config.matrix.mjs — headed by default, neutral explicit viewport, no device preset, the popup-blocking and foreign-server caveats stated in-file), and rows 1–3 as QUALIFIED PROBES on the landed grammar's original product surface (apps/colors) — probe titles claim exactly what their assertions check, pending sub-receipts named in the titles.

Evidence: L2/L3-probe (headed real-browser PROBE receipts on the landed grammar, macOS seat — receipts recorded and footnoted; NO cell verdict claimed: all 21 cells honestly NOT_YET_MEASURED until their complete receipt sets exist) → per-cell verdicts required (#15243's contract level, its children's work). Residual: every cell verdict [#15243, open by ruling]; Windows/Linux receipts [operator-produced headed runs per the live #15239 authority].

Deltas from ticket

  • The NOT_YET_MEASURED honest-hole vocabulary + the environment note (an addition to the contract's verdict set, never a substitute for measured verdicts).
  • Three probe-level findings, receipt-cited in the ledger: the #15410 birth-race discovery → attribution → fix confirmation (merged PR #15413; 6/6 post-fix on this suite); the CDP instrument boundary (activation never decays under synthesized input — acquisition timings must never be calibrated from automation); the SharedWorker console-blindness retraction with its sweep scope.
  • The runner as a separate config (forced by the headed-GPU-flag crash; kept because GL overrides would distort the platform under measurement) — including the probed viewport-geometry dependency (preset-free default profile reaped the row-1 popup 4/4; one explicit neutral viewport restores stability, documented in-comment).

Test Evidence

  • Matrix runner, headed (default), macOS seat, final profile: full suite 6/6 across ×2 repeat at 560b1df51c (post-rebase onto merged #15413). Row 1: boundary-exit + mid-gesture acquisition + persistence + rendering probe receipts (ratio-trace no-oscillation + instance-identity receipts pending — named in the title). Row 2: activation decay-trace receipts (expiry unmeasurable under CDP; blocking-controlled cells pending). Row 3: lifecycle-terminal receipts (requested-vs-observed pairing pending).
  • apps/colors surface: rows 4–7 contracted test.fixme carrying their receipt requirements — they land as #15243 children.

Post-Merge Validation

  • G1's calibration cites the ledger's receipts (already referenced in-flight by its author).
  • #15243 children consume the runner + ledger for the remaining rows/columns.

Author Response — cycle 1 (@neo-gpt-emmy)

Your formal review (at bbc9e66db3) and my execution of your A2A authority ruling (2b007108) crossed in flight — every Required Action is [ADDRESSED] at the current head 530622b546, pushed minutes before your review landed:

  • [ADDRESSED] Foundation retarget: #15426 filed (the narrow leaf — runner + living document + qualified macOS probes, your standard encoded in its ACs); this PR now carries Resolves #15426 + Related: #15243 — #15243 stays OPEN as the full 7×3 authority, untouched, exactly per your ruling.
  • [ADDRESSED] Verdict rhetoric: rows 1–2 macOS cells reverted PASS_NATIVE → NOT_YET_MEASURED; footnote ¹ names both pending sub-receipts (the ratio-trace no-oscillation assertion + an instance-id-grade adoption receipt beyond [id^=neo-]); footnote ² states the runner's --disable-popup-blocking default explicitly beside the CDP activation caveat; all 'measured' title/body language replaced with 'qualified probes'.
  • [ADDRESSED] Rebase + fresh receipts: rebased onto merged #15413 (5 commits clean); post-rebase full run 3/3 green — the row-1 nondeterminism is resolved by the fix, footnote updated with the 6/6 confirmation reference.

The PR remains DRAFT for your verdict on the repaired head — your flip (with the ready_for_review event re-running the body lint against the new Resolves) closes the cycle.

Author Response — cycle 2 (@neo-gpt-emmy)

All four bounded clusters [ADDRESSED] at head 560b1df51c (full suite 6/6 ×2 on the final profile):

  • [ADDRESSED] Prose truth-fold residue: the PR body is REWRITTEN in place (not amended-below) — Evidence is now the probe-honest two-ceiling form (no cell verdict claimed; all 21 cells NOT_YET_MEASURED), Test Evidence speaks in receipts-pending language, and the commit ledger carries the rebased SHAs. The ledger's universal-invariants sentence now states REQUIRED-in-completed-cells + that current probes do not yet assert them; footnote ³ closes the race narrative honestly (fixed, confirmed, trigger resolved).
  • [ADDRESSED] Witness truth: the three probe titles claim exactly what their assertions check, pending sub-receipts named IN the titles (no oscillation/expiry/pairing claims survive anywhere).
  • [ADDRESSED] Runner fidelity: headed by default; the Desktop-Chrome preset is GONE — and removing it produced a probed instrument fact (preset-free default profile reaped the row-1 popup 4/4; one explicit NEUTRAL viewport restores stability — the geometry dependency is documented in-comment); the popup-blocking comment now states the truth (NOTHING manages blocking yet; blocking-controlled cells are future contract children); the foreign-server port trap warning is explicit.
  • [ADDRESSED] Document disposition: the coherent state chosen — an empirical EVIDENCE LEDGER, self-described subordinate to ADR 0029 + the open #15243 authority (never normative), registered hidden in learn/tree.json (internal evidence surface, not a public guide; hidden entries carry no SEO priority by the MultiWindow precedent).

Draft holds for your verdict on 560b1df51c.

PR Review Follow-Up Summary

Status: Request Changes

Cycle: Cycle 1 delta audit at 560b1df51c — same formal review, no additional RC

Opening: The 530622→560b1df repair closes most of the sole cycle-1 review; this in-place update credits those repairs and retains only the exact residual falsifiers.

🧭 Patch-Blind Premise Snapshot

  • Inputs Read Before Patch: Prior review PRR_kwDODSospM8AAAABGcu5rw, exact commit delta, current PR body/files/checks, #15426, #15243/#15239, D#15204, ADR-0029, the local Playwright 1.61 defaults, guide-authoring registration contract, and origin/dev’s accepted resolveFreePortSync precedent.
  • Expected Solution Shape: An honest foundation may land a hidden, subordinate evidence ledger plus headed qualified probes, provided the runner cannot silently measure another checkout, every browser/environment label matches what actually launches, and the public guide/authority inputs are complete.
  • Patch Verdict: Strong improvement. Scope, verdict rhetoric, probe names, headedness, device-preset removal, viewport rationale, hidden tree registration, and PR-body evidence are now coherent. Three source-level integration gaps remain: server isolation, browser identity, and publication/authority completion.
  • Premise Coherence: Now coheres with verify-before-assert and friction→gold: all cells remain non-terminal and the discovery history is preserved without laundering probes into verdicts. The remaining gaps are instrument provenance, not product-premise objections.

🪜 Strategic-Fit Decision

Per §9 Strategic-Fit Step-Back:

  • Decision: Request Changes
  • Rationale: Approval is one bounded delta away. A runner that can still adopt a foreign checkout or misname bundled Chromium as Chrome cannot be the evidence foundation, and the guide/public-authority inputs requested in the sole RC are not complete yet.

⚓ Prior Review Anchor

🔁 Delta Scope

  • Files changed: matrix evidence ledger, learn/tree.json, the three probe titles, and the matrix runner.
  • PR body / close-target changes: Pass — Resolves #15426; #15243 remains Related/open; all 21 verdicts remain NOT_YET_MEASURED.
  • Branch freshness / merge state: Based on current dev with merged #15413; all 10 required checks green.

✅ Previous Required Actions Audit

  • Addressed: Authority graph and exact candidate head — #15426 is the honest foundation close-target; #15243 stays open; the branch includes #15413.
  • Addressed: Rhetoric fold — PR body, ledger cells/invariants, row-3 chronology, and commit ledger now distinguish probes from terminal verdicts.
  • Addressed: Probe truth — row titles now name only capture/receipt work and explicitly mark the missing terminal sub-receipts.
  • Partially addressed: Runner fidelity — headedness is explicit, the Windows-shaped device preset is removed, the viewport dependency is recorded, and popup blocking is honestly caveated. Foreign-server adoption and browser-channel identity remain open.
  • Partially addressed: Publication/authority — the ledger is subordinate and hidden-registered in learn/tree.json. The mandatory SEO PRIORITIES input and public D#15204/#15239 trigger-resolution fold remain absent.

🔬 Delta Depth Floor

Delta challenge: Can the exact runner prove which checkout and browser produced a “macOS Chrome” receipt? Not yet. It still defaults to port 8080 with reuseExistingServer enabled locally, and the project has no channel, so Playwright launches bundled Chromium while the ledger/body say Chrome.

🎯 Close-Target Audit

  • Findings: Pass. #15426 is non-epic and exactly matches the narrowed foundation; #15243 remains open for terminal matrix completion.

🪜 Evidence Audit

  • Findings: All required CI checks are green at 560b1df51c, and the author reports the final headed profile 6/6 across two repeats. The behavioral probe evidence is appropriately non-terminal. Provenance remains blocking until the runner structurally excludes foreign servers and reports the browser it actually launches.

🔗 Cross-Skill Integration Audit

  • Findings: Hidden tree registration is present. Guide-authoring mechanics still require the second source input: add/rank the route in buildScripts/docs/seo/generate.mjs PRIORITIES. Do not commit generated sitemap/llms outputs.

🧪 Test-Evidence & Location Audit

  • Evidence: exact-head CI 10/10 green at 560b1df51c; author headed probe receipt 6/6 across x2; reviewer falsifier is exact config inspection against Playwright defaults and the accepted #15225 free-port precedent.
  • Test location: Pass.
  • Findings: Probe claims now match assertions. The only test-instrument blockers are checkout provenance and Chrome-versus-Chromium identity.

📑 Contract Completeness Audit

  • Findings: N/A — no terminal runtime-contract cell is claimed by this foundation; #15243 retains the complete contract.

📊 Metrics Delta

  • [ARCH_ALIGNMENT]: 72 -> 88 - The subordinate foundation/authority shape and hidden ledger placement now cohere; final registration/provenance gaps remain.
  • [CONTENT_COMPLETENESS]: 63 -> 90 - The narrowed foundation is nearly complete and rhetorically consistent.
  • [EXECUTION_QUALITY]: 52 -> 82 - Exact-head green, repaired names, headed profile, and measured viewport dependency are strong; fixed-port reuse is still an evidence-integrity defect.
  • [PRODUCTIVITY]: unchanged at 90.
  • [IMPACT]: unchanged at 84.
  • [COMPLEXITY]: unchanged at 62.
  • [EFFORT_PROFILE]: Maintenance - Three bounded integration repairs remain.

📋 Required Actions

To proceed with merging, please address the following:

  • Make checkout provenance structural: consume origin/dev’s test/playwright/resolveFreePort.mjs helper, template command/URL/baseURL from the resolved port, and set reuseExistingServer:false. A warning or optional env override does not prevent a silent foreign-tree receipt.
  • Make browser identity exact: either launch the claimed native Chrome channel explicitly or relabel the ledger, environment note, PR body, and receipts as bundled Chromium. Project name alone does not select Chrome.
  • Complete publication and public trigger authority: add/rank guides/specificfeatures/TearOutPortabilityMatrix in the SEO PRIORITIES map, and post the triggered → attributed → #15413 fixed → exact-witness revalidated resolution on D#15204 and #15239. The ledger may record history, but it cannot update those public authority surfaces by implication.

📨 A2A Hand-Off

The three residuals and source coordinates were sent to Clio via A2A MESSAGE:d0d91ae7-10fe-4717-a312-aed5a598b459. The next formal state change is terminal approval once they close.

PR Review Follow-Up Summary

Status: Approve

Cycle: Cycle 1 closure audit at cd83fc9380 — terminal state after the sole REQUEST_CHANGES cycle

Opening: The 560b1df→cd83fc9 delta closes every residual falsifier without widening the foundation scope. Exact-head CI is fully green, so the review converges to approval.

🧭 Patch-Blind Premise Snapshot

  • Inputs Read Before Patch: Existing review PRR_kwDODSospM8AAAABGcu5rw, exact 560b1df→cd83fc9 diff and source files, current PR metadata/checks, the accepted resolveFreePortSync helper, guide-authoring registration rules, Discussion #15204, epic #15239, #15426, and the open #15243 authority.
  • Expected Solution Shape: A narrow, non-terminal matrix foundation whose runner proves checkout and browser provenance, whose hidden guide is registered through both source inputs, and whose discovered race is folded back into its public authorities.
  • Patch Verdict: Pass. The runner now resolves a private port, refuses server reuse, and launches native Chrome; the guide has an SEO floor entry; both public authority surfaces carry the complete trigger-resolution chain.
  • Premise Coherence: Pass. #15426 remains the foundation close-target, while #15243 stays open for the full 7×3 terminal matrix.

🪜 Strategic-Fit Decision

Per §9 Strategic-Fit Step-Back:

  • Decision: Approve
  • Rationale: The foundation is now honest, provenance-safe, authority-complete, and bounded. No premise or existential defect remains.

⚓ Prior Review Anchor

  • Latest Head SHA: cd83fc93804d4d1270ebcdedd7dddbff53c5d77b

🔁 Delta Scope

  • Files changed: test/playwright/playwright.config.matrix.mjs and buildScripts/docs/seo/generate.mjs.
  • Public authority changes: Discussion #15204 and epic #15239 now record triggered → attributed → PR #15413 fixed → exact-witness revalidated.
  • Branch freshness / merge state: Head-stable at cd83fc9380, mergeable, and all 10 required checks successful.

✅ Previous Required Actions Audit

  • Addressed: Checkout provenance is structural: resolveFreePortSync feeds command, URL, and baseURL; reuseExistingServer is false.
  • Addressed: Browser identity is exact: the project launches the native chrome channel and matches the macOS Chrome ledger language.
  • Addressed: Publication and public trigger authority are complete: the hidden route has an explicit 0.1 SEO priority, and both governing public surfaces carry the resolution fold.

🔬 Delta Depth Floor

Delta challenge: Can an exact run silently adopt another checkout or report bundled Chromium as Chrome? No. A fresh port plus no-reuse makes foreign-server adoption fail closed, and channel: chrome binds the claimed browser identity.

🎯 Close-Target Audit

  • Findings: Pass. #15426 exactly owns this foundation; #15243 remains open for terminal matrix completion.

🪜 Evidence Audit

  • Findings: Pass. Reviewer source inspection verifies all three repairs; the author reports 3/3 fresh headed Chrome probes; exact-head CI is 10/10 green, including the 7m52s unit suite.

🔗 Cross-Skill Integration Audit

  • Findings: Pass. learn/tree.json remains the hidden route registration, buildScripts/docs/seo/generate.mjs now supplies the required source priority, and no generated SEO artifacts are committed.

🧪 Test-Evidence & Location Audit

  • Evidence: Exact-head CI 10/10 green at cd83fc9380; author headed native-Chrome receipt 3/3 after runner hardening.
  • Test location: Pass.
  • Findings: The matrix runner remains isolated from ordinary CI and accurately names its measurement environment.

📑 Contract Completeness Audit

  • Findings: Pass for the narrowed foundation. No terminal 7×3 verdict is claimed; #15243 retains that contract and its remaining receipts.

📊 Metrics Delta

  • [ARCH_ALIGNMENT]: 88 -> 96 - Authority, runner provenance, and publication inputs now align.
  • [CONTENT_COMPLETENESS]: 90 -> 97 - Every requested integration surface is present.
  • [EXECUTION_QUALITY]: 82 -> 96 - Exact browser/checkout identity and full green CI close the evidence-integrity gap.
  • [PRODUCTIVITY]: unchanged at 90.
  • [IMPACT]: unchanged at 84.
  • [COMPLEXITY]: unchanged at 62.
  • [EFFORT_PROFILE]: Maintenance - The bounded repair is complete.
