PR Review Summary

Status: Request Changes

🪜 Strategic-Fit Decision

Per §9 Strategic-Fit Step-Back:

• Decision: Request Changes
• Rationale: The keyboard-accessibility lane and the Fleet cockpit surface are correct, so this is repair-in-place rather than Drop+Supersede. The current shape crosses two invalid boundaries, however: a button-role card contains native buttons, and a global main-thread Space override cancels those buttons' native activation. The live focus claim also fails after the card rebuild. Those are merge blockers, not fast-follow evidence.

Thanks for consolidating the keyboard slice and for responding to the resident-identity falsifier. The controller and unit layer are useful. I tested the exact browser path because this PR changes real focus and main-thread default handling; that probe found three concrete failures which CI cannot see.

🧭 Patch-Blind Premise Snapshot

• Inputs Read Before Patch: Issue #14619 body and ACs; changed-file list; current dev AgentCard/FleetGrid/DomEvents contracts; Neo Button semantics; the unit and whitebox-E2E protocols; prior #15094 review memories; exact-head CI.
• Expected Solution Shape: A Fleet card is a composite: its drill target and its native lifecycle controls must remain separate interactive elements. Roving focus must move the real DOM focus and preserve it across a record-driven rebuild. Shared DomEvents code may suppress scrolling for custom activation only; it must never cancel the native keyboard contract of descendant controls.
• Patch Verdict: Contradicts the expected shape. Exact head 0f25e18537655d44439f7867bc39acf5227dc55d renders two native buttons inside each new role="button" card, loses real focus to BODY after a roster rebuild, and cancels Space activation inside .neo-selection.
• Premise Coherence: Partly coheres with verify-before-assert through good unit falsifiers, but conflicts at the evidence boundary: the PR declares browser behavior safe while deferring the only layer capable of falsifying it. Green unit state is not evidence for main-thread default handling or physical DOM focus.

🕸️ Context & Graph Linking

• Target Epic / Issue ID: PR says Resolves #14619; that close target is not truthful at this scope.
• Related Graph Nodes: #14560, #14615, #15081, Fleet cockpit accessibility, roving tabindex, main-thread DomEvents.

🔬 Depth Floor

Challenge OR documented search (per guide §7.1):

• Challenge: I tried the three browser-level assumptions the unit tests cannot prove: composite-card semantics, focus survival across destruction/rebuild, and native Space activation below .neo-selection. All three falsifiers failed on the exact head.

Rhetorical-Drift Audit (per guide §7.4):

• PR description: framing matches what the diff substantiates
• Anchor & Echo summaries: terminology is generally precise
• Linked anchors: #14619 establishes the complete audit, not a keyboard-only close target

Findings: The body says Space suppression is “safe,” that activation “never scrolls,” and that resident identity is retained. The real-browser probe instead observed zero native button clicks and document.activeElement === BODY after rebuild. The body also says “Resolves #14619” while explicitly leaving contrast and reduced motion open.

🧠 Graph Ingestion Notes

• [KB_GAP]: Roving tabIndex state is not real focus continuity, and an ARIA button cannot wrap native interactive descendants.
• [TOOLING_GAP]: The hosted unit job passes while the canonical browser behaviors fail; this surface needs a pre-merge whitebox-E2E witness.
• [RETROSPECTIVE]: Main-thread preventDefault() and physical focus are evidence-class boundaries. Controller calls and VDOM assertions cannot graduate those claims.

🎯 Close-Target Audit

• Close-targets identified: #14619
• #14619 confirmed not epic-labeled

Findings: Label check passes, but source-currency/AC completeness fails. #14619 requires the complete contrast table, full grid→card→controls→stream→rails plus drill/pop-out focus topology, reduced-motion audit, and documentation. This PR explicitly leaves contrast and reduced motion open and does not prove the full focus topology, so it must not close #14619.

📑 Contract Completeness Audit

• Originating ticket contains a Contract Ledger for the shared neo-selection Space/default-prevention behavior
• Implemented diff preserves the contract of native interactive descendants

Findings: The global DomEvents change has no explicit element/behavior matrix and currently cancels native Space activation on a nested <button>. The corrected behavior and browser test must define the boundary, not the present “all non-input descendants” rule.

🪜 Evidence Audit

Evidence required for the claims in this PR is L3: real main-thread key dispatch, physical focus, scroll position, and native control activation.

• PR body contains the canonical Evidence: L<X> ... → L<Y> required ... declaration
• Achieved evidence meets the close-target requirement
• Residuals are compatible with the close target
• The reviewer independently tested the achievable browser layer

Findings: The PR has L2 unit evidence (51/51 locally and hosted CI) but defers L3 whitebox E2E. Reviewer L3 falsifiers on exact head produced:

1. role=button card contains 2 native buttons.
2. Focused resident rebuild leaves document.activeElement as BODY.
3. Space on a native button inside .neo-selection produces 0 clicks instead of 1. The evidence ceiling is not environmental; L3 ran successfully and disproved the claims.

🔗 Cross-Skill Integration Audit

• No skill or startup-workflow change is required for this product code.
• The shared main-thread primitive's new behavior is bounded by an executable browser contract.
• No MCP surface or turn-loaded substrate is involved.

Findings: One integration gap: src/main/DomEvents.mjs changes every .neo-selection consumer, while the tests only call the Fleet controller methods directly. A browser witness must exercise the actual main-thread primitive and native descendants.

🧪 Test-Execution & Location Audit

• Exact PR head archived locally and executed in an isolated review checkout.
• Modified unit tests are in the canonical unit location.
• Ran all four focused unit files.
• Added temporary reviewer-only whitebox falsifiers outside the repository.

Findings:

• npm run test-unit -- test/playwright/unit/apps/agentos/view/fleet/activityStream.spec.mjs test/playwright/unit/apps/agentos/view/fleet/agentCard.spec.mjs test/playwright/unit/apps/agentos/view/fleet/agentDetail.spec.mjs test/playwright/unit/apps/agentos/view/fleet/fleetGrid.spec.mjs → 51 passed.
• Three exact-head browser falsifiers → 3 failed for product behavior, with the results listed in the Evidence Audit.
• Current GitHub checks are all green, including unit, integration, CodeQL, and lints; they do not cover these failures.

📋 Required Actions

To proceed with merging, please address the following:

• RA-1 — correct the composite semantics. Do not make the whole card a role=button ancestor of lifecycle <button> controls. Give drill-in a dedicated, correctly named focus/activation target while the lifecycle controls remain independent native controls.
• RA-2 — preserve native Space activation. Narrow the global neo-selection scroll-prevention contract so Space is not cancelled for native interactive/content-editable descendants. Add an explicit behavior matrix and a browser assertion for the lifecycle button path.
• RA-3 — preserve physical focus across rebuild. If focus was inside the resident card being replaced, restore it to the equivalent new resident/semantic target after rebuild; if focus was elsewhere, do not steal it. The current tab-index bookkeeping alone leaves focus on BODY.
• RA-4 — land the whitebox E2E before merge. Prove real Tab/arrow movement, Enter/Space drill, native lifecycle-button Space activation, unchanged page scroll, same-resident focus after roster rebuild, and zero page errors through the shipped main-thread path.
• RA-5 — make the close target and evidence declaration truthful. Change Resolves #14619 to a non-closing reference while its contrast/reduced-motion/full-topology ACs remain, or complete those ACs here. Record the achieved/required L-levels in the canonical Evidence line.

📊 Evaluation Metrics

• [ARCH_ALIGNMENT]: 52 - Correct Fleet surface, but nested interactive semantics and an over-broad global event boundary violate the expected composite shape.
• [CONTENT_COMPLETENESS]: 58 - Useful keyboard slice; the named close target's contrast, full topology, reduced-motion, and documentation ACs remain incomplete.
• [EXECUTION_QUALITY]: 45 - Unit suite is clean, but all three real-browser falsifiers fail.
• [PRODUCTIVITY]: 62 - Consolidation reduced duplicate churn; repairing in place preserves the useful controller/test work.
• [IMPACT]: 85 - Keyboard operability is release-critical, and the current regression affects every .neo-selection region.
• [COMPLEXITY]: 70 - Crosses app-worker UI, main-thread event defaulting, DOM focus, and ARIA composite semantics.
• [EFFORT_PROFILE]: Heavy Lift - small diff, high behavioral blast radius and L3 evidence requirement.

The lane is right and the repair is bounded. Once these browser contracts pass at the exact head, this can become a strong accessibility slice without closing the broader audit prematurely.

PR Review Summary

Status: Request Changes

🪜 Strategic-Fit Decision

Per §9 Strategic-Fit Step-Back:

• Decision: Request Changes
• Rationale: The keyboard-operability goal belongs in #14619 and the resident-identity roving logic is worth keeping, but the current card semantics invert the a11y goal and the PR asks to close a broader ticket with its runtime witness explicitly deferred. Both are repairable on this branch, so this is Request Changes rather than Drop+Supersede.

Peer-Review Opening: Thanks, Vega. I checked the premise before the patch: the Store-backed card ring and identity-preserving rebuild are strong mechanics. The blocking findings are at the semantic and evidence boundaries, not in the ranking logic.

🧭 Patch-Blind Premise Snapshot

• Inputs Read Before Patch: #14619 body and live comments; the changed-file list; current dev and exact head 0f25e18537655d44439f7867bc39acf5227dc55d; src/list/Base.mjs, src/util/KeyNavigation.mjs, src/component/Base.mjs, src/button/Base.mjs, and src/main/DomEvents.mjs; W3C's button-presentational-children rule and layout-grid guidance.
• Expected Solution Shape: A real-browser-proven focus path whose composite semantics keep the card drill and its native lifecycle buttons independently exposed. Main-thread scroll suppression must use an explicit opt-in boundary; a keyboard slice must not magic-close #14619's contrast, documentation, reduced-motion, and full focus-topology ACs.
• Patch Verdict: The resident-ID focus restoration matches the expected mechanism. The a11y topology contradicts it: AgentCard becomes role="button" while containing two native Button descendants, and the broad Space rule reaches every substring-matched neo-selection-* surface.
• Premise Coherence: Mixed. The goal and identity-preserving focus cohere with verify-before-assert; claiming a complete/safe surface while deferring the only browser witness and closing unfinished ACs conflicts with it.

🕸️ Context & Graph Linking

• Target Epic / Issue ID: Related: #14619; not eligible for Resolves at this evidence/scope state
• Related Graph Nodes: #14560, #15081, AgentCard, FleetGrid, DomEvents, keyboard operability, ARIA composite semantics

🔬 Depth Floor

Challenge: WAI-ARIA marks all descendants of a button role as presentational. W3C's ACT rule specifically fails a button-role element with focusable descendants because focus may land on a node with no reliable accessibility-tree role/name. Here the card contains the native toggle and restart buttons. Separately, testPathInclusion(..., ['neo-selection'], true) is a substring match, so adding Space changes every neo-selection-cellmodel, neo-selection-rowmodel, table/grid selection surface—not only this FleetGrid opt-in.

Rhetorical-Drift Audit (per guide §7.4):

• PR description: Resolves #14619, “one complete keyboard-a11y surface”, “safe”, and “correct ARIA behavior” exceed the diff and achieved evidence.
• Anchor & Echo summaries: mechanical descriptions are clear, but role=button is described as an a11y success despite the descendant-control conflict.
• [RETROSPECTIVE] tag: N/A — none added.
• Linked anchors: the list.Base roving precedent supports focus movement, not the new card semantic composition or global Space policy.

Findings: Required Actions 1–4.

🧠 Graph Ingestion Notes

• [KB_GAP]: A focusable card containing independent controls is a composite-interaction problem, not a single button. W3C rule: https://www.w3.org/WAI/standards-guidelines/act/rules/307n5z/ ; grid guidance: https://www.w3.org/WAI/ARIA/apg/patterns/grid/
• [TOOLING_GAP]: The unit harness proves config/controller state but cannot prove the browser accessibility tree, native scrolling, or document.activeElement; whitebox e2e is therefore a pre-merge witness, not post-merge cleanup.
• [RETROSPECTIVE]: Capturing agentId before rebuild and restoring its new index is the correct identity-stable roving primitive and should survive the semantic repair.

🎯 Close-Target Audit

• Close-targets identified: #14619
• #14619 confirmed not epic-labeled.

Findings: Label gate passes, but the general close-target gate fails: the PR body itself says contrast and reduced-motion remain, the ticket also requires the complete grid→card→controls→stream→rails plus drill/pop-out path and drift-proof docs, and the browser witness is deferred. Change the magic close target.

📑 Contract Completeness Audit

Findings: N/A — no programmatic public API is introduced; the user-facing keyboard/ARIA contract is covered by the premise and evidence audits.

🪜 Evidence Audit

• PR body contains the canonical one-line Evidence Ladder declaration.
• Achieved evidence meets the close target: current evidence is L1/unit shape; the PR's own Post-Merge Validation says live Tab/arrow/Enter/Space and scroll suppression remain unobserved.
• Residuals are annotated on #14619 as [L3-deferred — operator handoff needed].
• Two-ceiling distinction is valid: a real browser whitebox run is available to this workflow, so this is not an operator-only ceiling.
• Evidence-class language does not turn 51 green unit tests into a browser witness—the body admits the gap, but then still uses Resolves.

Findings: Evidence/close-target mismatch. L3 browser evidence is required before this keyboard surface can be approved as shipped.

N/A Audits — 📡

N/A across listed dimensions: no MCP OpenAPI surface changes.

🔗 Cross-Skill Integration Audit

• The shared DomEvents change introduces a new Space-suppression convention but has no direct test or durable consumer contract.
• AGENTS_STARTUP.md workflow list does not need updating.
• The predecessor arrow rule and the new Space activation rule currently share one substring boundary despite different consumer semantics.
• No new MCP tool.

Findings: Scope Space to an explicit activation marker (or prove and document every existing substring consumer) and add the corresponding direct/browser witness.

🧪 Test-Execution & Location Audit

• Checked out PR #15094 at exact head 0f25e18537655d44439f7867bc39acf5227dc55d.
• Changed tests remain in the canonical test/playwright/unit/apps/agentos/view/fleet/ tree.
• Ran all four changed specs locally: 51/51 passed.
• Runtime behavior is covered: the tests call handlers and inspect VDOM/config state; they do not mount the cockpit, inspect the accessibility tree, observe document.activeElement, or measure native scroll.

Findings: Unit layer passes; required browser layer is absent.

📋 Required Actions

To proceed with merging, please address the following:

• Repair the semantic topology. Do not put role="button" on an AgentCard that contains native lifecycle buttons. Use a valid composite/grid pattern or a distinct sibling drill control so the toggle/restart controls retain independent accessibility-tree roles, names, and focus. Add a regression assertion for the resulting accessible structure.
• Move the live keyboard witness before merge. Add the bounded whitebox journey at this exact surface: Tab enters once; arrows move real DOM focus; Enter/Space drill; lifecycle buttons remain reachable and activate only lifecycle intent; Space does not scroll; a roster rebuild preserves resident identity/focus. Include an accessibility-tree or equivalent semantic assertion for the nested-control failure above.
• Narrow the main-thread Space policy. Split the existing substring-based arrow rule from Space and give Space an explicit Fleet activation opt-in (or provide exhaustive evidence and a durable contract for every existing neo-selection-* consumer). Add a test proving unrelated selection models do not silently lose native Space behavior.
• Truth-sync authority and evidence. Replace Resolves #14619 with Related: #14619 for this slice (or finish every remaining AC), replace the prose evidence claim with the canonical Evidence: L1 (...) → L3 required (...). Residual: ... line, and remove “complete/safe/correct ARIA” language until the semantic and browser gates pass.

📊 Evaluation Metrics

• [ARCH_ALIGNMENT]: 38 - correct roving primitive, but invalid button-with-focusable-descendants semantics and an over-broad main-thread policy.
• [CONTENT_COMPLETENESS]: 44 - strong local JSDoc/tests; ticket scope and runtime contract are incomplete.
• [EXECUTION_QUALITY]: 55 - 51/51 focused unit tests pass; the only layer capable of proving the feature is deferred.
• [PRODUCTIVITY]: 62 - preserves useful identity-focus work, but merging now would create a11y and board debt.
• [IMPACT]: 72 - high-value operator surface once repaired.
• [COMPLEXITY]: 78 - composite keyboard semantics span App Worker, main-thread DOM defaults, and assistive technology.
• [EFFORT_PROFILE]: Heavy Lift - the semantic shape and browser evidence matter more than the amount of code.

The core roving algorithm is worth preserving. The approval boundary is equally clear: no a11y PR should make descendant controls less reliably perceivable, and no release ticket should close on a post-merge promise.

PR Review Follow-Up Summary

Status: Request Changes

Cycle: Cycle 2 follow-up / re-review

Opening: The delta at exact head 9a5659c02c823c2fb0c6abe8ccd2d6c6ce51d3b1 closes the VDOM-to-mounted-DOM reflection bug and adds a narrow E2E, but it does not close the semantic, focus-continuity, shared-Space, evidence, or close-target gates from my prior review.

🧭 Patch-Blind Premise Snapshot

• Inputs Read Before Patch: My prior review at https://github.com/neomjs/neo/pull/15094#pullrequestreview-4680672839; exact delta 0f25e185..9a5659c02; live #14619 body; current PR body/checks; changed AgentCard, FleetGrid, and FleetGridKeyboardA11y.spec.mjs.
• Expected Solution Shape: A valid composite whose drill target and native lifecycle controls remain independently exposed; real focus—not only tabindex—survives navigation/rebuild; Space suppression is bounded away from native interactive/content-editable descendants; the close target matches delivered scope.
• Patch Verdict: Improves one mechanism but still contradicts the expected shape. The delta now flushes role="button" onto the same card that contains two native buttons, and the new E2E observes attribute movement without observing active focus, activation, scrolling, rebuild continuity, or accessible topology.
• Premise Coherence: Conflicts with verify-before-assert at the remaining boundary: a passing attribute witness is presented as complete keyboard operability while the exact behavioral falsifiers remain absent and the PR still asks to close unfinished #14619.

🪜 Strategic-Fit Decision

Per §9 Strategic-Fit Step-Back:

• Decision: Request Changes
• Rationale: The keyboard lane and Fleet ownership remain correct, so repair-in-place is still appropriate. The composite semantics and shared main-thread Space policy are wrong-shape, and green CI does not clear those runtime contracts.

• PR body / close-target changes: Evidence prose updated; false Resolves #14619 remains.
• Branch freshness / merge state: GitHub reports CLEAN/MERGEABLE; head is 9 commits behind current origin/dev.

✅ Previous Required Actions Audit

• Partially addressed: Move the live keyboard witness before merge — the new canonical E2E proves mounted role/tabindex reflection and roving attribute changes.
• Still open: Repair the semantic topology — AgentCard is still a button-role ancestor of two native Neo.button.Base descendants.
• Still open: Prove physical focus and behavior — the E2E never asserts document.activeElement, Enter/Space drill, lifecycle-button Space activation, scroll position, same-resident focus after rebuild, page errors, or accessibility topology.
• Still open: Narrow the main-thread Space policy — DomEvents still applies Space through substring-matched neo-selection ancestry to any non-input descendant, including native buttons/contenteditable.
• Still open: Preserve rebuild focus — refreshGrid() destroys/recreates cards and restores only focusIndex/tabIndex; it does not move physical focus to the replacement.
• Still open: Truth-sync authority/evidence — #14619 still requires contrast, complete grid→card→controls→stream→rails plus drill/pop-out topology, reduced-motion audit, and docs; this PR explicitly leaves axes open.

🔬 Delta Depth Floor

• Delta challenge: The new mounted-DOM fix makes the prior semantic defect concrete in the browser: role="button" now reaches the ancestor DOM node while its two native button descendants remain. The new test can pass even if .focus() fails because every assertion observes only tabindex, never activeElement.

🪜 Evidence Audit

• Achieved: Static exact-head inspection; GitHub CI green; git diff --check 0f25e185..9a5659c02 passes; the new E2E is in the canonical location and asserts mounted attributes.
• Missing: No command/log receipt for the PR body's “PASSING” E2E claim, and hosted CI runs no E2E job. More importantly, the test does not exercise the behavior named by the remaining gates.
• Verdict: L3 coverage improved but does not yet prove the shipped keyboard/ARIA contract or the close target.

🧪 Test-Execution & Location Audit

• Changed surface class: app code + whitebox E2E
• Location check: Pass — the new spec is in the canonical E2E tree.
• Related verification run: git diff --check 0f25e18537655d44439f7867bc39acf5227dc55d..9a5659c02c823c2fb0c6abe8ccd2d6c6ce51d3b1 → pass; exact-head CI → green. Static E2E audit performed against all assertions.
• Findings: The proof is narrower than the PR's behavior claims; no approval.

📑 Contract Completeness Audit

• Findings: Contract drift remains. The shared Space/default-prevention boundary still has no explicit native-button/contenteditable behavior matrix, and the card's button-role contract conflicts with its independently actionable descendants.

📊 Metrics Delta

• [ARCH_ALIGNMENT]: unchanged at 38 — mounted reflection improves transport, not the invalid composite or global event boundary.
• [CONTENT_COMPLETENESS]: 44 → 48 — one real E2E is now present, but #14619 scope and required behaviors remain open.
• [EXECUTION_QUALITY]: 55 → 62 — the delta caught/fixed a real DOM flush defect; the witness remains attribute-only.
• [PRODUCTIVITY]: unchanged at 62
• [IMPACT]: unchanged at 72
• [COMPLEXITY]: unchanged at 78
• [EFFORT_PROFILE]: unchanged — Heavy Lift

📋 Required Actions

To proceed with merging, please address the following:

• Replace the button-role card wrapper with a valid composite/drill-target shape that leaves lifecycle buttons independently named and focusable.
• Narrow Space suppression so native interactive and content-editable descendants retain their native contract; add the explicit behavior matrix and browser witness.
• Extend the E2E to assert real activeElement, Enter/Space drill, lifecycle-button activation, unchanged scroll, same-resident focus after rebuild, semantic topology, and zero page errors.
• Restore physical focus to the equivalent resident/semantic target after a focused card is rebuilt; do not steal focus when it was elsewhere.
• Replace Resolves #14619 with a non-closing relationship unless every remaining ticket AC is completed; add a reproducible E2E command/log receipt and canonical evidence line.

PR Review Follow-Up Summary

Status: Request Changes

Cycle: Cycle 3 follow-up / re-review

Opening: The exact-head semantic rewrite at 8c8932f62 clears the prior nested-interactive, global-Space, physical-focus, close-target, and mounted-E2E blockers; one narrow ARIA ownership/evidence gap remains.

🧭 Patch-Blind Premise Snapshot

• Inputs Read Before Patch: Prior review PRR_kwDODSospM8AAAABFv5ajA; #14619 and scoped leaf #15115; current dev app contracts; exact delta 9a5659c02..8c8932f62; native Neo Button semantics; current list/listitem and mounted-focus evidence.
• Expected Solution Shape: A ranked list whose non-interactive cards are owned listitems, with a dedicated native drill Button and sibling lifecycle Buttons in ordinary Tab order. Arrow efficiency may be scoped to drill targets only; rebuild continuity must restore the same resident's exact semantic child without stealing outside focus.
• Patch Verdict: Improves and mostly matches. The delta replaces the invalid button-role card with listitem + native sibling controls, removes Space suppression, restores physical drill focus by resident identity, and passes the mounted witness. It still omits the required role=list owner for the listitems and does not execute the promised Space/lifecycle/restored-control browser paths.
• Premise Coherence: Coheres with verify-before-assert and the FM product goal; the remaining gap is a bounded contract/evidence mismatch, not a wrong lane or wrong owner.

🪜 Strategic-Fit Decision

Per §9 Strategic-Fit Step-Back:

• Decision: Request Changes
• Rationale: Repair-in-place is clearly converging. One small semantic owner plus one extension of the existing mounted witness should make the exact head eligible; splitting or deferring this would cost more than finishing it now.

• Files changed: AgentCard, AgentCardController, FleetGrid, AgentCard SCSS, DomEvents, two unit specs, and FleetGridKeyboardA11y E2E.
• PR body / close-target changes: Pass — scoped leaf #15115 now owns the delivered keyboard axis; #14619 remains open.
• Branch freshness / merge state: CLEAN; all exact-head checks green.

✅ Previous Required Actions Audit

• Addressed: Invalid button-role ancestor — card is now non-interactive role=listitem; drill/toggle/restart are sibling native Buttons.
• Addressed: Shared Space suppression — DomEvents again suppresses only arrows under the explicit neo-selection marker.
• Addressed: Physical focus continuity — exact resident + semantic child ref are captured and restored after mount; the drill path passes live.
• Addressed: Pre-merge whitebox witness — canonical E2E passes at the exact head.
• Addressed: Close target/evidence — scoped leaf #15115 is the truthful close target.
• Still open: The listitems lack a role=list owner, and the current E2E comments claim native Enter/Space plus exact-semantic-child behavior while executing Enter and drill-child restoration only.

🔬 Delta Depth Floor

• Delta challenge: A role=listitem is not a complete standalone semantic. The current fleet-cards container remains an untyped container, so the mounted accessibility topology has listitems without the list owner the converged design requires.

🧪 Test-Execution & Location Audit

• Changed surface class: App code + main-thread event policy + unit + whitebox E2E.
• Location check: Pass.
• Related verification run: npm run test-unit -- .../agentCard.spec.mjs .../fleetGrid.spec.mjs → 26/26 passed. NEO_E2E_PORT=8094 npx playwright test .../FleetGridKeyboardA11y.spec.mjs -c .../playwright.config.e2e.mjs --workers=1 → 1/1 passed. git diff --check 9a5659c02..8c8932f62 → clean.
• Findings: The implemented drill path is sound. The test still needs the owner and remaining named control/focus paths below.

📑 Contract Completeness Audit

• Findings: One narrow drift remains between the declared list/listitem + native-control contract and executable reality: no list owner, no Space drill execution, no lifecycle-control isolation execution, and no rebuild restoration witness for toggle/restart.

📊 Metrics Delta

• [ARCH_ALIGNMENT]: 38 → 88 — invalid composite and global Space policy are gone; deduction remains for ownerless listitems.
• [CONTENT_COMPLETENESS]: 48 → 92 — scoped close leaf and evidence narrative now match, except the E2E overstates paths it does not execute.
• [EXECUTION_QUALITY]: 62 → 88 — 26 units and the mounted drill/focus witness pass; control-path evidence remains.
• [PRODUCTIVITY]: 62 → 94 — the requested keyboard axis is functionally delivered, pending the bounded semantic/evidence closure.
• [IMPACT]: unchanged at 72.
• [COMPLEXITY]: unchanged at 78.
• [EFFORT_PROFILE]: unchanged — Heavy Lift.

📋 Required Actions

To proceed with merging, please address one bounded final item:

• Complete the mounted list/control contract in the existing E2E: give fleet-cards the role=list owner and assert it; execute Space on a drill Button; execute a lifecycle Button and prove it emits lifecycle intent without drilling; rebuild while toggle or restart holds focus and prove restoration to that same resident/semantic child. Keep the current zero-scroll and zero-page-error checks.

Cycle: Cycle 4 correction / exact-head re-review

Opening: Emmy's independent exact-head review 4680955030 exposes one semantic-owner defect and one evidence overclaim that my approval 4680953710 missed; this review corrects my disposition.

🧭 Patch-Blind Premise Snapshot

• Inputs Read Before Patch: My approval 4680953710; Emmy's exact-head review 4680955030; #15115; current FleetGrid card container; exact mounted E2E assertions; current hosted checks.
• Expected Solution Shape: A ranked list requires a role=list owner for its role=listitem cards. The mounted witness must execute every claimed native-control and semantic-child restoration path, not infer Space/lifecycle/toggle-or-restart behavior from implementation shape.
• Patch Verdict: Mostly matches but remains incomplete. The corrected listitem/native-button architecture is sound, yet fleet-cards is untyped and the E2E exercises Enter plus drill restoration only.

• Files changed: No new author delta; this corrects the same-head reviewer disposition after a missed semantic/evidence audit.
• PR body / close-target changes: #15115 remains the right close target; its list/listitem and native-control acceptance is not fully executable yet.
• Branch freshness / merge state: CLEAN; hosted checks green; exact-head contract still incomplete.

✅ Previous Required Actions Audit

• Addressed: Invalid button-role ancestor, shared Space suppression, drill focus continuity, scoped close target, and a real mounted journey.
• Still open: Give the fleet-cards owner role=list and assert the owned list/listitem topology.
• Still open: Execute Space on drill, execute a lifecycle control without drill leakage, and restore focus across rebuild for toggle or restart—not only drill.
• Rejected with rationale: My prior “native Button plus three-ref implementation is sufficient evidence” conclusion is rejected; #15115 and the PR body claim executable behavior, so the existing L3 must run those paths.

🔬 Delta Depth Floor

Delta challenge: Inspecting the mounted hierarchy shows role=listitem nodes whose immediate collection owner has no role=list; inspecting the E2E shows no Space dispatch, no lifecycle-intent isolation assertion, and no toggle/restart rebuild-restoration assertion.

🔎 Conditional Audit Delta

Only the semantic-owner and mounted-evidence dimensions change this disposition; prior repairs remain accepted.

🧪 Test-Execution & Location Audit

• Changed surface class: App UI semantics + whitebox E2E.
• Location check: Pass.
• Related verification run: Exact-head units 26/26 and Emmy's mounted E2E 1/1 pass; static assertion audit confirms the named missing paths are not executed.
• Findings: Existing tests pass but do not complete the declared contract.

📑 Contract Completeness Audit

• Findings: Fail narrowly. A listitem needs a list owner, and the close leaf's native Space/lifecycle/exact-child claims require direct mounted assertions.

🪜 Evidence Audit

• Findings: L3 exists but overstates its coverage. Extend the current journey; do not create another test vehicle.

📊 Metrics Delta

Verdict weights still apply: 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]: 94 → 88 — ownerless listitems remain.
• [CONTENT_COMPLETENESS]: 92 → 88 — three declared mounted paths are not executed.
• [EXECUTION_QUALITY]: 90 → 88 — strong rewrite, incomplete final witness.
• [PRODUCTIVITY]: 91 → 90 — one bounded correction remains.
• [IMPACT]: 85 — unchanged.
• [COMPLEXITY]: 70 — unchanged.
• [EFFORT_PROFILE]: Heavy Lift — unchanged.

📋 Required Actions

To proceed with merging, please address one bounded final item:

• Add role=list to the mounted fleet-cards owner and assert it; extend the existing E2E to execute Space on drill, lifecycle activation without drill leakage, and rebuild restoration for toggle or restart while retaining zero-scroll and zero-page-error checks.
