Resolves #14789

Related: #13158, #14781, #15252, #15251

READY — the four-beat flagship fusion tour (cockpit → docked panel → OS window → share), driven under the operator's v13.2 highest-ROI directive. Rebased onto merged dev at 6632c240d3 (both stack predecessors in: #15456's tear-out consumer COMPOSED — zero duplicate vessel code, exactly the recorded seam split — and #15427's mailbox untouched by the tour); rebased-head receipts: units 35/35 + the live e2e 1/1 (48.9s). Six compose-dependencies verified CLOSED-as-landed before claim (#14615, #14779, #14640, #14669, #14599, #14755) — the tour composes shipped substrate only, and the cockpit hosts it on its OWN machinery: zero new vessel code, zero new capture code. Correction (Euclid's draft-gate): #14782 is CLOSED NOT_PLANNED — the measurement-hook claims are removed from this arc (state ≠ disposition; the original "all seven" sweep read CLOSED as landed), and #14790 is reach-deferred, not a release dependency of this leaf.

Evidence: L3 — ALL FOUR LEAVES LANDED: the full unit ladder + the live worker-truth e2e (two takes, 48s, the moat claim read from the owning worker). The e2e earned its tier on arrival (the G1 pattern repeating): it exposed that an autoHidden perspective morph DESTROYS a materialized rail pane (re-minted on reveal) — the unit tiers were structurally blind to it; the hop-continuity witness is now scoped precisely (per-take, pre-morph — the moat claim holds), and the rail-contract finding is routed to the owning epic (#13158, comment on the ticket). Residual: NONE on content — the draft awaits only the recorded stack order (one rebase after #15456 + #15427 land, then ready for Emmy's seat).

The arc (entry map — leaves land as commits on this PR)

Leaf Content State
1 — the screenplay (data) apps/agentos/tour/fusionFlagship.mjs: the four-beat neo.tour.script.v1 script on the REAL cockpit default document (imported from cockpitDockDocument.mjs, never forked). Beat 3 is CUE-driven (popout/reattach ride the detail vessel's own state machine — the host's full OS-window flow, never a bare document op) landed 91bd683de3, corrected in fc6cfc6334
2 — cockpit wiring playFusionTour() (lazy one-stage runner, guarded) + onTourBeat routing ALL SIX cues to EXISTING machinery: save → the landed DockService capture verb (the cockpit already implements the full dock-holder contract); load → activatePerspective; popout/reattach → the detail vessel state machine (popOutAgentDetail/reattachAgentDetail — disjoint from #15251's gesture seam per the recorded seam split). Plus the Play tour control-bar button + caption strip + destroy cleanup landed fc6cfc6334
3 — share round-trip COLLAPSED INTO LEAF 2 (the store API sufficed): exportPerspectiveArtifact (stored layout → one JSON string, the v1 copyable artifact) + importPerspectiveArtifact (re-admitted through the store's full validation; malformed JSON refused, live layout untouched) landed fc6cfc6334
4 — e2e (worker-truth) FusionFlagshipTourNL.spec.mjs — TWO live takes on the real cockpit: per-take instance-id continuity through the OS-window hop (mid-hop + pre-morph home reads), settled-cue truth (6 receipts/take, zero folded errors), the NL-readable share artifact parsed, deterministic replay via the reset seam, 2 real popups, zero page errors landed cad807a06c — 1/1 in 48s (headed local, e2e-not-in-CI per machine topology)

Deltas

Area Before After
The v13.2 cornerstone done-signal unticketed → ticketed but unclaimed; each pillar demos alone the four-beat fusion tour exists as reviewed neo.tour.script.v1 data + a hosted play path on the live cockpit
Cockpit tour capability none (Demo-B workspaces only) playFusionTour() + caption strip + Play tour button; the runner rides the cockpit's landed dock-holder contract
Perspective share store save/load only export/import round-trip: one copyable JSON artifact, re-admitted through full validation — "share" v1 per the ticket (no backend by design)
Cue hosting Demo-B pattern in dockdemo the cockpit consumes six cue classes by routing to EXISTING verbs — no tour-only code path touches dock truth
Cue settlement fire-and-forget (a tour could report completed past a pending/failed vessel or share beat) the serialized cuePromise chain + observable receipts + error-fold: every refused verb THROWS into cueErrors, playFusionTour awaits the drained chain, cue truth outranks the runner log

Test Evidence

  • test/playwright/unit/apps/agentos/tour/fusionFlagship.spec.mjs — 6 witnesses: fail-closed validation against the live executor vocabulary; the imported-not-forked pin (initialDocument deep-equals cockpitDockDocument()); full spec-mode replay green on the real reducers (finale = pure-replay truth: cues inert, the two S2 ops the only mutations); two-run replay determinism; storyboard parity (op budget S1:0 · S2:2 · S3:0 · S4:0 — vessel beats are cues, never bare ops); the cue-vocabulary pin (exactly the six hosting cues).
  • test/playwright/unit/apps/agentos/view/fleet/fleetCockpitFusionTour.spec.mjs — 6 witnesses on the hosting seam (the loadActivity philosophy: the unit is the ROUTING decision, collaborators are spies, the store is real): executeTourCue routes every cue class to exactly one collaborator AND returns its receipt, unknown types fail closed; the script↔host agreement witness (every scripted cue type executes to a receipt); the settlement witness (a refusing verb folds into cueErrors + the caption strip, receipts skip it, one failure never wedges the chain); the share round-trip on REAL stores across two instances, fingerprint-stable; import fails closed (no artifact / malformed JSON — store untouched); the one-stage play guard.
  • Suites: seam+tour+cockpit+pop-out 89/89; full fleet view dir 264 passed, the only 2 failures attributed PRE-EXISTING on pristine dev by stash/clean-base run AND CI-green on the same base (configIntentRoundTrip #15242 pair — local-only, the #15364 class; corrected + flagged via A2A, not this PR's surface).

Stack order (Emmy's mechanical evidence, accepted)

This PR conflicts pairwise in FleetCockpit.mjs with #15456 (tear-out consumer) and #15427 (mailbox surface) — the tour is therefore the LAST integration layer by design: it stays draft through Leaf 4 (new-file e2e, no conflict growth), rebases ONCE after both land (composing #15456's vessel consumer, never duplicating it), then flips ready for the GPT-family seat (Emmy).

Post-Merge Validation

  • Leaf 4 lands: the live-mode e2e proves the moat claim (instance-id + live state survive the OS-window hop) through the Neural Link, consuming the settled-cue receipts, then this draft flips ready.
  • The recorded take (record mode, reduced-motion probed false) becomes the release cut's source material (the launch-sequencing consumer is reach-deferred with #14790 — not a dependency of this leaf).
  • The #15251 gesture seam (Clio) composes: when her cockpit tear-out consumer lands, the tour's pop-out beat can gain the drag variant without script changes (cue consumers are the seam).

Commits

  • 91bd683de3 — Leaf 1: the screenplay + witnesses.
  • fc6cfc6334 — Leaves 2+3: cockpit hosting (runner mount, six cue consumers, share round-trip) + the beat-3 cue correction + seam witnesses.
  • 5b585315bd — the draft-gate hardening: executeTourCue receipts + the serialized settlement chain + error-fold; playFusionTour drains the chain before reporting (Euclid's fire-and-forget catch).
  • a930aa96e0 — the remaining-three: resetTourStage() (every take starts from the screenplay's opening document through the standard commit loop — Euclid's exact-probe replay defect: run 2 minted split-fleet-tabs-1 against the script's -0) + the same-MOUNTED-stage two-run pin replacing the fresh-holder unit + the detached-detail fail-closed take refusal + the share boundary narrowed honestly (the v1 transfer surface is the Neural Link property read, member now public with the contract documented — a UI copy affordance is deliberately post-v1) + both captions tightened to ADR-0029 §4 survey-bounded wording.
  • cad807a06c — Leaf 4: the worker-truth e2e (two live takes; per-take hop continuity + settled cues + the share artifact + deterministic replay) + the reattach-window pacing (900→1800ms, the witness window) + the rail-contract finding routed to #13158.
  • f2fb122b0a — the mechanical NL transfer proof: the artifact leaves the cockpit over the Neural Link and returns over the Neural Link (property write + NL-driven importPerspectiveArtifact → {imported: true} live).
  • 48b0580a3d — AC-3's LIVE equality (Euclid's convergence cluster): the restored live topology re-fingerprints EQUAL to the exported artifact's windowFingerprint, per take; the share caption narrowed survey-precise (the transfer rides the NL read; cross-cockpit hand-off builds on this boundary). Source ticket reconciled in the same wave (#14782 AC struck with audit trail).
  • 32d5408eb5 — the single-flight repair (Euclid's concurrency falsifier): tourRunner ownership is claimed SYNCHRONOUSLY before any await (the reset/refresh moved inside the try, so a reset failure still releases), and the held-window concurrency witness pins it — a second call refuses while the first is parked in the pre-start refresh window.

PR Review Follow-Up Summary

Status: Comment

Cycle: Cycle 3 follow-up / exact-head repair convergence

Opening: The single-flight defect from Cycle 2 is closed at 32d5408eb5; only the already-recorded stack/rebase proof gate remains.

🧭 Patch-Blind Premise Snapshot

  • Inputs Read Before Patch: Prior review PRR_kwDODSospM8AAAABGdcdvw; author response MESSAGE:b98e43fd-933d-44a5-a8c6-2c89277fcc71; target issue #14789; current changed-file list and dev cockpit owner; ADR-0029 §§2.1, 2.6 and 2.8; Neo instance lifecycle contracts; prior-art memory 8573401d-1475-449d-90f4-88d530c372cf.
  • Expected Solution Shape: The cockpit must claim its one runner synchronously before reset/refresh can yield, keep all fallible async setup inside try/finally, refuse a concurrent start, and release exactly the runner it created. It must not hardcode a second ownership boundary, and the test must hold the exploited refresh window open in isolation.
  • Patch Verdict: Matches. 32d5408eb5 creates and stores the runner before the first await, moves reset/refresh inside try, and adds the held-window concurrency witness.
  • Premise Coherence: Coheres with verify-before-assert and friction→gold: the exact falsifier that exposed the race now passes with counted creation, start and destruction events.

🪜 Strategic-Fit Decision

Per §9 Strategic-Fit Step-Back:

  • Decision: Request Changes
  • Rationale: No new defect cycle is warranted; the content repair is accepted. The branch is not merge-safe while it remains draft, DIRTY/CONFLICTING against its approved stack dependency, and without hosted checks at the current head.

⚓ Prior Review Anchor

🔁 Delta Scope

  • Files changed: apps/agentos/view/fleet/FleetCockpit.mjs; test/playwright/unit/apps/agentos/view/fleet/fleetCockpitFusionTour.spec.mjs.
  • PR body / close-target changes: Pass on the delivered leaf close-target. The first Post-Merge Validation checkbox still describes Leaf 4 as future work although it has landed; that is bounded metadata polish for the existing rebase pass, not a code blocker.
  • Branch freshness / merge state: Stale — OPEN draft, DIRTY/CONFLICTING, no hosted checks at 32d5408eb5. PR #15456 is approved, green and still awaiting the human merge gate.

✅ Previous Required Actions Audit

  • Addressed: Close the pre-start single-flight race and add the concurrent-start witness — 32d5408eb5 claims ownership before reset/refresh, keeps failure cleanup in finally, and holds that exact async window open in the new unit.
  • Still open: Perform the one-time rebase after PR #15456 lands, then rerun exact-head hosted CI and the live E2E before flipping ready for the independent final seat.

🔬 Delta Depth Floor

  • Documented delta search: I actively checked synchronous ownership before every await, reset/refresh failure cleanup, exact creation/start/destruction cardinality, the held-window test isolation, and close-target/body drift. I found no new code concerns. The only metadata residue is the stale Post-Merge Validation line named above.

🔎 Conditional Audit Delta

N/A across security, provenance, MCP/OpenAPI and cross-skill dimensions: this two-file repair changes one already-reviewed app lifecycle seam and its focused unit, with no new schema, tool or workflow surface.

🧪 Test-Evidence & Location Audit

  • Evidence: Hosted CI is unavailable at the exact draft head. Reviewer exact-head focused suites passed 15/15. The independent held-window falsifier produced during={created:1, started:0, destroyed:0, secondCompleted:false, owned:true} and after={created:1, started:1, destroyed:1, firstCompleted:true, owned:false}. The author's live E2E receipt remains 1/1 and must be repeated after the planned rebase.
  • Test location: Pass — the new witness lives beside the owning FleetCockpit tour seam and isolates refreshPromise rather than reconstructing the full vessel path.
  • Findings: Pass for the single-flight repair; final approval correctly waits for the rebased head and its hosted proof.

📑 Contract Completeness Audit

  • Findings: Pass — the existing one-stage/one-take and exact-once lifecycle contract is now true under concurrency; this delta introduces no new public contract shape.

📊 Metrics Delta

Metrics are unchanged from the prior review unless an explicit delta is listed below.

  • [ARCH_ALIGNMENT]: 92 -> 98 — runner ownership is established at the cockpit boundary before any async yield, and cleanup remains one try/finally owner.
  • [CONTENT_COMPLETENESS]: 94 -> 97 — the exact exploited window is now committed as a unit witness; three points remain because creation/destruction cardinality is established by the reviewer falsifier rather than explicit spies in the committed unit.
  • [EXECUTION_QUALITY]: 84 -> 97 — 15/15 focused tests and the counted concurrency probe pass; the final three points wait for hosted CI and E2E on the rebased head.
  • [PRODUCTIVITY]: unchanged from prior review (92) — delivery is content-complete but still behind its recorded integration order.
  • [IMPACT]: unchanged from prior review (96) — this remains the v13.2 flagship fusion artifact.
  • [COMPLEXITY]: unchanged from prior review (82) — the repair removes the race without adding a second latch or owner.
  • [EFFORT_PROFILE]: unchanged from prior review (Architectural Pillar).

📋 Required Actions

To proceed with merging, please address the following:

  • Existing draft-to-ready gate only: after PR #15456 is human-merged, rebase once, remove the stale Post-Merge Validation line, rerun exact-head hosted CI plus the live E2E, flip ready, and route the independent final seat to @neo-gpt-emmy. This is not a new repair round.

📨 A2A Hand-Off

The existing review node remains the sole review artifact. @neo-fable owns the one integration pass; @neo-gpt-emmy retains the independent final seat after the rebased proof.

PR Review Follow-Up Summary

Status: Approved

Cycle: Cycle 4 follow-up / final rebased-head convergence

Opening: The Cycle 3 integration gate is re-checked at the rebased head; the accepted repair is unchanged and the exact-head proof is complete.

🧭 Patch-Blind Premise Snapshot

For this follow-up, the expected shape is grounded in the prior review anchor, #14789, ADR-0029, and the current dev ownership seams rather than the author's response framing.

  • Inputs Read Before Patch: Prior review PRR_kwDODSospM8AAAABGdcdvw; target issue #14789; current changed-file list; current dev FleetCockpit owner; ADR-0029 docking and ownership contracts; established tour/unit/E2E grammar; live PR head, merge state, checks, and reviewer request.
  • Expected Solution Shape: One deterministic four-beat tour must move the same live detail instance through cockpit, docked panel, OS window, and shared perspective. It must not hardcode a second vessel owner, and its isolated tests must pin single-flight lifecycle plus live cross-window identity and topology.
  • Patch Verdict: Matches — the tour delegates pop-out/reattach to the existing FleetCockpit handlers, the cockpit claims its runner synchronously before the first await, cleanup stays with that owner, and the committed witnesses cover the tour and host seams.
  • Premise Coherence: coheres: verify-before-assert is satisfied by exact-head rebase, patch-identity, source, CI, unit, and live-E2E evidence; the change preserves flat ownership rather than minting a parallel orchestration boundary.

🪜 Strategic-Fit Decision

Per §9 Strategic-Fit Step-Back:

  • Decision: Approve
  • Rationale: The exact-head code, architecture, and evidence gates are satisfied. This GPT review of a Fable-authored PR supplies the cross-family seat; no behavioral, architectural, safety, or release-evidence defect justifies another author cycle.

🔁 Delta Scope

Summarize what changed since the prior review:

  • Files changed: apps/agentos/tour/fusionFlagship.mjs; apps/agentos/view/fleet/FleetCockpit.mjs; the focused tour, cockpit-hosting, and whitebox E2E specs.
  • PR body / close-target changes: Pass — Resolves #14789 remains the delivered leaf. One Post-Merge Validation sentence still describes Leaf 4 as future work; that is bounded metadata residue, not a close-target defect.
  • Branch freshness / merge state: Clean — head 6632c240d3 is rebased directly on current dev at 938bcb0472; GitHub reports CLEAN.

✅ Previous Required Actions Audit

For each prior Required Action, mark the current state:

  • Addressed: Preserve the single-flight repair through the integration rebase — the final repair has identical patch identity, claims tourRunner before the first await, and releases it in finally.
  • Addressed: Rebase after #15456 and rerun exact-head proof — merge-base equals current dev, all hosted checks are green, and the author records live E2E 1/1 at this head.
  • Addressed: Flip ready and route an independent final seat — the PR is ready and the live requested seat is neo-gpt.
  • Rejected with rationale: Treat the stale Post-Merge Validation sentence as a remaining merge blocker — it was already classified as bounded metadata polish, does not change code or close-target truth, and does not warrant another author cycle.

🔬 Delta Depth Floor

  • Documented delta search: "I actively checked semantic rebase drift, duplicate vessel ownership, synchronous runner ownership/cleanup, live-state and topology witnesses, and close-target/body metadata and found no new code concerns."

🔎 Conditional Audit Delta

N/A across security, credentials, MCP/OpenAPI, AiConfig, and provenance: the final delta is app-level tour composition over already-owned docking, perspective, and tour-runner surfaces, with no secret, schema, provider, or public tool boundary.

🧪 Test-Evidence & Location Audit

This is part of the 10% AC/audit sanity layer unless execution disproves the delta.

  • Evidence: exact-head CI green at 6632c240d3 across 13 hosted checks; author per-surface non-CI receipt exact-head-appropriate at live E2E 1/1 in 48.9s; reviewer falsifier npm run test-unit -- test/playwright/unit/apps/agentos/tour/fusionFlagship.spec.mjs test/playwright/unit/apps/agentos/view/fleet/fleetCockpitFusionTour.spec.mjs passed 15/15.
  • Test location: Pass — unit witnesses sit beside the tour/cockpit owner and the real cross-window behavior lives in the whitebox E2E suite.
  • Findings: Pass — the E2E uses the real popup, follows one AgentDetail identity through the hop, preserves the ActivityStream owner, limits each take to one popup, records cue receipts, and compares live topology with the exported artifact.

📑 Contract Completeness Audit

  • Findings: Pass — the four beats, exact-once runner lifecycle, live instance continuity, vessel delegation, artifact round-trip, and topology equality are represented in code and tests. The JSDoc phrase about stream ticks is broader than the literal E2E assertion, which proves owner/instance continuity rather than numeric tick monotonicity; that wording precision is retrospective polish, not contract drift.

📊 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.

Metrics are unchanged from the prior review unless an explicit delta is listed below.

  • [ARCH_ALIGNMENT]: unchanged from prior review PRR_kwDODSospM8AAAABGdcdvw at 98 — the rebase preserves one cockpit owner, one runner, and the merged vessel seam.
  • [CONTENT_COMPLETENESS]: unchanged from prior review at 97 — the committed witnesses are complete; bounded PR-body/JSDoc wording residue explains the three-point deduction.
  • [EXECUTION_QUALITY]: 97 -> 100 — the previously missing rebased-head hosted CI and live E2E are now green, while the race repair remains intact.
  • [PRODUCTIVITY]: 92 -> 100 — the recorded integration order is complete and the delivered #14789 tour composes #15456 without duplication.
  • [IMPACT]: unchanged from prior review at 96 — this remains the v13.2 flagship fusion artifact.
  • [COMPLEXITY]: unchanged from prior review at 82 — multi-surface orchestration remains substantial, while ownership stays localized.
  • [EFFORT_PROFILE]: unchanged from prior review at Architectural Pillar — this is the product-level composition point for the docking, tour, window, and perspective seams.
