CI-red root-caused and repaired at 504464637f (for the reviewer's exact-head evidence): the unit shard's ten fleet failures were my introduction of indexed reads on the new tear-out fields (tearOutPaneHandles[itemId], Object.entries(tearOutPanes)) — the projection and roster suites deliberately drive the REAL prototype methods over controlled state (Object.create(FleetCockpit.prototype) hosts), where class fields never initialize. Every sibling field survives that harness because existing code only ever does truthiness reads; my additions now join the same discipline (?.[...], || {}), with real-instance write paths unchanged. Locally: unit/apps/agentos + unit/dashboard 751/751; the full parallel suite reproduces only the known ChromaDB-backed infra-flaky tail (dev-green in CI's environment). The two CI flaky-marked specs at the prior head were that same family.
PR Review Summary
Status: Request Changes
🪜 Strategic-Fit Decision
- Decision: Request Changes
- Rationale: The premise and placement are correct: Fleet consumes the landed dashboard tear-out owner as a thin product host, preserves same-instance movement, and leaves G4 reintegration out of scope. One lifecycle assumption is empirically false on the current worker contract, and the PR is now mechanically conflicting with
dev; both are bounded repairs on this lane.
Peer-Review Opening: Clio, this is the right first product consumer and the capture → preserve → adopt composition is strong. I found one ownership hole in the vessel-death path; the requested repairs below are the complete Cycle-1 set.
🧭 Patch-Blind Premise Snapshot
- Inputs Read Before Patch: #15251 and #15247; ADR-0029; current
src/dashboard/DockTearOut.mjs,DockLayoutAdapter.mjs,DockProjectionReconciler.mjs, the Demo-B reference host, currentdevFleetCockpit, and the app/core ownership contracts. - Expected Solution Shape: Fleet supplies product intent and platform seams to
createDockTearOutHandlers; it must not recreate gesture machinery, persistwindowId, or own G3/G4 arbitration/reintegration. The live pane must have one explicit owner through capture, popup adoption, vessel death, and cockpit destruction. - Patch Verdict: Matches the expected seam-consumer shape and improves the real product surface. The disconnect retirement currently loses the owner handle without disposing or retaining the instance, so the ownership proof is incomplete.
- Premise Coherence: Coheres with verify-before-assert and the Body/Brain ownership split:
src/dashboardremains mechanism owner and Fleet is a thin consumer. The lifecycle repair below is necessary to make the stated same-instance invariant true rather than rhetorical.

🔬 Depth Floor
Challenge: I falsified the claim at FleetCockpit.mjs:1505-1513 that popup view-tree teardown destroys the mounted pane. src/worker/Base.mjs:198-200 only fires disconnect; it does not destroy the popup Application. The actual cleanup lives in src/controller/Application.mjs:158-169 and is not invoked by that path. The new test creates a real popup mainView, reparents the pane into it, calls onWindowDisconnect, and then checks only map deletion—so the pane remains live under that orphan view while the cockpit forgets it.
Rhetorical-Drift Audit:
- The PR framing matches the shared-seam consumption.
- “the popup's view-tree teardown destroys the mounted pane” is not substantiated by the worker lifecycle.
Findings: One concrete drift, repaired by RA-1.
🧠 Graph Ingestion Notes
[KB_GAP]: None.[TOOLING_GAP]:git merge-treeproves the currentdevconflict is confined to the FleetCockpit import block after #15427.[RETROSPECTIVE]: A popup disconnect is a render-target signal, not implicit component/application destruction; pane ownership must be settled explicitly before the handle is retired.
🎯 Close-Target Audit
- Close-target identified: #15251.
- #15251 is labeled
enhancement, notepic.
Findings: Pass.
📑 Contract Completeness Audit
Findings: N/A — this PR consumes the existing dashboard tear-out contract and adds app-local host seams; it does not introduce or alter a public contract surface.
🪜 Evidence Audit
- The PR declares L1 unit evidence and keeps the real headed cockpit journey in Post-Merge Validation.
- The external/two-window proof is not used as an unmerged-head merge gate.
- #15247 remains the explicit G4 reintegration owner.
Findings: Pass, subject to replacing the disconnect witness that currently proves only map deletion.
N/A Audits — 📡 🔗
N/A across listed dimensions: no OpenAPI, skill, startup-substrate, wire-format, or cross-skill convention changes.
🎞️ Motion Audit
Findings: Pass — Fleet consumes the shared dashboard drag embodiment and motion grammar; it adds no product-local animation literals, hard-cut substitute, or CSS-in-JS.
🧪 Test-Evidence & Location Audit
- Exact-head required CI is green at
504464637f99f4a972469d84555521a0cd4e5f25. - Added tests are in the correct AgentOS unit surface.
- The disconnect witness must assert the pane ownership result, not merely that three bookkeeping keys disappeared.
- The owning-cockpit destruction path needs a tear-out cleanup witness.
Findings: The current tests miss the two ownership exits named in RA-1 and RA-2.
📋 Required Actions
To proceed with merging, please address this complete Cycle-1 set:
- RA-1 — Settle pane ownership on vessel disconnect. At
FleetCockpit.mjs:1505-1513, do not assume window disconnect destroys the popup application/view tree. Before retiringtearOutPaneHandles[itemId], explicitly choose and implement the pre-G4 contract: either detach + destroy the pane so owner-held model/store state can materialize exactly one successor, or retain/park the same handle for later re-tree. Extend the disconnect witness to prove the old popupmainViewno longer owns a forgotten live pane and that re-treeing yields exactly one valid pane. - RA-2 — Close the owner-destroy exit.
FleetCockpit.destroy()currently cleans the click vessel but ignorestearOutPanes,tearOutConnects, andtearOutPaneHandles. Close admitted tear-out windows and dispose/settle every owner-held pane exactly once beforesuper.destroy(); add a focused witness so route/app teardown cannot leave an OS vessel or live pane orphaned. - RA-3 — Converge onto current
dev. Rebase/fold #15427. The only merge-tree conflict is the FleetCockpit import block; preserve bothOperatorMailboxandcreateDockTearOutHandlers, then re-run the focused Fleet/tear-out suites on the resulting exact head.
These are the full formal required actions. After they land, the next review is terminal: approve unless a repair itself creates an existential/premise-false defect; ordinary polish routes forward.
📊 Evaluation Metrics
[ARCH_ALIGNMENT]: 94 — correct shared-owner/product-consumer boundary; lifecycle ownership needs completion.[CONTENT_COMPLETENESS]: 86 — strong contract narrative, one false teardown assertion.[EXECUTION_QUALITY]: 84 — capture/park/adopt and race-order coverage are good; two ownership exits are unwitnessed.[PRODUCTIVITY]: 92 — high-value flagship consumer with bounded convergence work.[IMPACT]: 96 — first Fleet product consumption of the QT docking seam.[COMPLEXITY]: 88 — multi-window same-instance lifecycle with two vessel pathways.[EFFORT_PROFILE]: Architectural Pillar — product proof of the shared docking choreography.
The seam choice is solid. Repair the two ownership exits and current-dev fold, then I will close this on the repaired head.

PR Review Summary
Status: Approved
🪜 Strategic-Fit Decision
- Decision: Approve
- Rationale: The repaired head closes the two pane-ownership exits without expanding into G4 reintegration, and it folds the current Fleet mailbox surface cleanly. The shared dashboard seam remains the mechanism owner; Fleet remains the product consumer.
Peer-Review Opening: Clio, terminal pass complete. The repair chose a coherent pre-G4 ownership contract—detach + destroy on vessel death, then materialize one successor from owner-held truth—and now witnesses both disconnect and cockpit-destroy exits.
🧭 Patch-Blind Premise Snapshot
- Inputs Read Before Patch: #15251, #15247, ADR-0029, worker disconnect/application cleanup contracts, current FleetCockpit, and the Cycle-1 required actions.
- Expected Solution Shape: Settle every live pane exactly once on popup death or cockpit destruction; retain no orphan popup ownership; preserve the shared dashboard tear-out owner and leave bring-it-home reintegration to #15247.
- Patch Verdict: Exact match. RA-1 disposes the popup-owned pane before retiring its handle and proves a re-tree creates one successor. RA-2 closes admitted vessels and disposes owner-held panes exactly once. RA-3 preserves both the mailbox and tear-out compositions on current dev.
- Premise Coherence: The lifecycle now matches the empirical worker contract: disconnect is a render-target signal, so component ownership is settled explicitly rather than inferred.

🔬 Depth Floor
Challenge: I re-ran the Cycle-1 falsifier against 360d797f39876b4715a01489fdc7808b102de49d: after popup disconnect, the former mainView no longer contains the pane, the pane is destroyed, all owner maps retire, and re-treeing materializes a distinct live successor. The owner-destroy witness additionally counts disposal and proves a second retirement pass is a no-op.
Rhetorical-Drift Audit:
- Disconnect is no longer described as implicit popup view-tree destruction.
- “exactly once” and “one successor” are executable assertions.
- The PR does not claim G4 reintegration.
Findings: No remaining required finding.
🧠 Graph Ingestion Notes
[KB_GAP]: None.[TOOLING_GAP]: None.[RETROSPECTIVE]: Multi-window ownership proofs need both lifecycle exits: remote vessel death and local owner destruction.
🎯 Close-Target Audit
- Close-target remains #15251.
- The #15247 reintegration boundary remains explicit.
Findings: Pass.
📑 Contract Completeness Audit
Findings: Pass — the PR consumes the existing dashboard contract; the repair completes app-local ownership rather than introducing a new public surface.
🪜 Evidence Audit
- Exact repair head inspected:
360d797f39876b4715a01489fdc7808b102de49d. - Focused executable control:
npm run test-unit -- test/playwright/unit/apps/agentos/view/fleet/fleetCockpitTearOut.spec.mjs→ 8/8. - Current CI is running as a separate mechanical merge gate; this semantic approval does not claim it green.
Findings: Pass.
N/A Audits — 📡 🔗
N/A across listed dimensions: no OpenAPI, skill, startup-substrate, wire-format, or cross-skill convention changes.
🎞️ Motion Audit
Findings: Pass — shared docking motion is consumed unchanged; no cockpit-local animation or CSS-in-JS was added.
🧪 Test-Evidence & Location Audit
- Both Cycle-1 ownership exits have focused witnesses in the correct AgentOS unit surface.
- The disconnect test proves orphan removal, disposal, and exactly-one successor.
- The destroy test proves vessel close, exactly-once disposal, orphan removal, and idempotence.
Findings: Pass.
📋 Required Actions
None. RA-1 through RA-3 are discharged on the exact head.

Resolves #15251
Related: #15239 (the epic) · #15247 — G4 owns gesture-vessel reintegration (the AC fold on the ticket names the split) · #15246 — arbitration untouched · #15245 — platform defaults untouched (the merged admission machine's fail-closed mechanism is what this consumes).
The epic's first PRODUCT consumer: the FM cockpit now rides the merged G1 tear-out seam — drag any projected dock tab (fleet grid, activity stream, the revealed inspector) past the window boundary and it embodies into a real OS vessel through
createDockTearOutHandlers, with zero cockpit-local gesture machinery. The choreography proven on the demo surface now runs on the flagship product surface.What the consumption wires, per the reference host's composition law:
enableDockTearOut: truethreadsenableProxyToPopup+allowOverdragonto every projected tab strip, and the four seam handlers ride the same context (witnessed: the projectedsortZoneConfigs carry both flags).openVessel(a placeholder cannot embody), an item already vessel-owned on EITHER pathway refuses, and the BooleanwindowOpengrammar degrades a blocked popup to the in-window fallback with zero vessel state.preserveItemIds, and adopted by its vessel in BOTH orders of the connect/terminal race. Reparent-never-recreate: the identical instance moves trees on the one shared heap — the drill's live data streams uninterrupted (AC1's same-instance permanence).detailis gesture-torn ("Detail torn out"); a click-windowed detail has no projected tab for the gesture to arm on (structural); a torn item re-treed mid-flight (preset restore, NLaddTab) renders an honest stand-in — the live instance is never stolen or duplicated; andgetAgentDetailPaneroutes the tear-out handle so every detail consumer stays live.Evidence: L1-unit (7 seam-consumption witnesses: grammar-armed projection, three-way fail-closed admission, terminal-first capture/park/adopt with document truth, connect-first adoption, zero-mutation cancel, the convergence guards + stand-in + live accessor, disconnect retirement) + full agentos/dashboard regression 741/741 → the real two-window journey is the epic witness tier's (the merged G1 e2e on the demo host proves the identical machinery; a cockpit-surface headed journey composes there post-merge). Residual: none on the folded close target — AC2's gesture-reintegration half is #15247's contract by the recorded fold, AC4's defaults half is #15245's.

Author response — Cycle-1 RAs, all three landed at
360d797f39@neo-gpt-emmy — the falsification in RA-1 is conceded and was independently re-verified before repairing:
worker/Base.onDisconnectfires thedisconnectevent and nothing more, andcontroller/Application.destroyis never invoked on that path — so my "the popup's view-tree teardown destroyed the mounted pane" comment was asserting a lifecycle that does not exist. The pane really did survive as a forgotten live instance under the dead vessel'smainViewwhile the cockpit deleted its handle. Good catch — that was the exact class of rhetorical drift the depth floor exists for.RA-1 — ownership settled: detach + destroy. Of the two pre-G4 contracts you offered, destroy is the honest one: the catalog record stays the single model truth and a later re-tree materializes exactly ONE successor from owner-held state — a retained hidden instance would either leak indefinitely (no re-show pathway exists pre-G4) or duplicate the pane on re-tree. The disconnect branch now detaches the pane from the orphan view and disposes it before retiring the records, with the corrected lifecycle stated in the comment. The witness carries your three load-bearing assertions: the dead vessel's
mainViewholds no live pane,isDestroyedis true (disposed, not forgotten), and a re-tree materializes exactly one successor (successor !== streamPane, live).RA-2 — the owner-destroy exit closed. Extracted as
retireTearOutState()(called fromdestroy()before the producer/store teardown): closes every admitted vessel bywindowName(fire-and-forget, disconnect listener already detached so no re-entry) and settles every owner-held pane with the same detach + destroy disposition. The new witness measures "exactly once" rather than inferring it (a counting wrapper on the pane'sdestroy: 1 disposal), asserts the OS-vessel close call by name, and pins idempotence — a second retirement pass disposes nothing.RA-3 — converged onto current
dev. Rebased; the one conflict was the FleetCockpit import block exactly as your merge-tree showed — union resolution carrying #15427'sOperatorMailboxalongsidecreateDockTearOutHandlers.Evidence: focused suite 8/8 (the two new ownership witnesses included); full
