Resolves #15648

The detail vessel's admission machine flapped silently on loaded seats: a legitimate cold boot exceeded the 10s connect window, the failed-timeout edge rolled the dock back, and the flap was visually identical to a user-initiated reattach — popOutAgentDetail had already answered detached: true, so nothing anywhere said an admission failed. Two changes, matching the ticket's options 1+3 (option 2's adaptive heartbeat deliberately deferred — see Deltas):

  1. Calibrated widening with the rationale in place: detailVesselConnectWindowMs 10000 → 20000. The number is justified against the healthy baseline (~1.3s born→windowed on a GL-fixed seat — the pre-#15664 environment inflated every historical boot measurement) and the ticket's live evidence (the same pop-out that flapped at 10s survived at 20s, minutes apart on one seat): ~15x healthy headroom, the cold-provider-beats-default class (#14182 precedent). The boundedness contract is untouched — a genuinely dead connect still rolls back.
  2. The flap witness: both silent failure edges (failed-timeout AND failed-blocked — they share the silence problem) now emit one self-describing console.warn line via a small @protected helper, carrying the edge kind, window name, and the bound that fired. lastDetailVesselFailure already persisted the state half through the rollback; the warn is the log half — the App-Worker console bridges into the Neural Link console stream, so harnesses and agents can distinguish a flap from a deliberate return without polling cockpit state.

Evidence: L2 in CI (unit seam) + L3 live (mounted headed witness plus the ticket's same-seat 20s survival receipt) → L3 required for #15648's loaded-seat behavior. No close-target residuals; a plain-dev rerun after #15814 and another loaded-seat capture remain non-closing post-merge validation.

Deltas from ticket

  • Option 2 (adaptive extension via a childapp boot-progress heartbeat) is deliberately NOT implemented: it introduces new cross-realm signaling machinery for a case the calibrated bound + the new observability may fully absorb. If a post-merge loaded-seat observation shows 20s still flapping legitimate boots, the heartbeat becomes a follow-up with that evidence attached — filed then, not speculatively now.
  • The failed-blocked edge got the same witness line (the ticket named only failed-timeout; both edges share the silent-flap problem and the same consumer).
  • Intake recorded a calibration correction on the ticket: pre-#15664 boot measurements from the e2e seat were inflated by the dead-GL environment; the widened bound is justified against the healthy baseline instead.

Test Evidence

  • test/playwright/unit/apps/agentos/view/fleet/ (touched suite's directory): 343/343 passed (22.1s, unit config, workers=1) — including both extended failure-edge tests, which assert the witness line with a paired console.warn capture/restore (the #15789 teardown discipline applied conspicuously).
  • Mounted proof (touched app surface apps/agentos fleet cockpit): FleetCockpitKineticNL.spec.mjs headed green (18.4s, two in-spec runs, identical beat logs) on this change. Environment note for honesty: the run executed with PR #15814's e2e config fix applied to the worktree for the run only (then restored — this PR's diff stays clean); on plain dev the witness dies from #15664's environment defect regardless of this change. Once #15814 merges, the witness covers this path with no special handling.
  • The timeout-vs-legit-boot distinction (AC4) rides the spec's existing injectable-window contract (detailVesselConnectWindowMs: 20 at instance creation) — no sleeps on production bounds.

Post-Merge Validation

  • After #15814 merges: kinetic witness headed green on plain dev (no run-only config application).
  • A real loaded-seat capture session observes either a surviving cold boot within 20s, or a failed-timeout witness line — either way the flap is now visible; if legitimate boots still flap, file the option-2 heartbeat follow-up with that observation attached.

Commits (if multi-commit)

  • Single commit: config calibration + witness helper + both edge call sites + spec extensions.

PR Review Summary

Status: Approve
Review Type: Cycle 1 (cold-cache)

🪜 Strategic-Fit Decision

Per §9 Strategic-Fit Step-Back:

  • Decision: Approve
  • Rationale: This is the smallest coherent repair at the existing vessel-admission authority: calibrate the finite guard from measured live behavior and expose the two rollback edges through the console surface already bridged to Neural Link. The state machine, boundedness, generation fencing, and document ownership remain intact; no Drop+Supersede is warranted.

Peer-Review Opening: Vega, the patch survives the premise challenge. You did not replace a correct guard with retry machinery; you widened it against the observed tail, preserved the dead-connect bound, and made the previously silent rollback externally legible.

🧭 Patch-Blind Premise Snapshot

  • Inputs Read Before Patch: #15648 body and both live intake comments; PR #15815 metadata/body/checks; current origin/dev FleetCockpit state machine and pop-out spec; #14182 calibration precedent; src/Neo.mjs, src/core/Base.mjs, src/state/Provider.mjs, src/data/Model.mjs, src/data/Store.mjs; the unit-test protocol/examples; Evidence Ladder; Agent OS structure map; exact commit/check metadata.
  • Expected Solution Shape: Keep one finite admission timer; widen only from live cold-seat evidence; preserve generation-guarded rollback for a dead join; expose failed-timeout (and the sibling failed-blocked edge) through existing state/log truth; inject a short window in unit tests and restore any global console interception symmetrically.
  • Patch Verdict: Exact head 27387c4545aa8232111c61fa71c8fa9c4df2dacd matches that shape. It changes only the non-reactive default, adds one protected warning helper plus two call sites, and extends the canonical existing spec. git diff --check is clean.
  • Premise Coherence: The ticket's live same-seat comparison already falsified “10s is sufficient” and showed the 20s configuration surviving. The ~1.3s healthy baseline prevents the calibration from being justified by the separately broken GL test environment.

🕸️ Context & Graph Linking

  • Target Issue: Resolves #15648 (leaf bug + ai, not an epic).
  • Related Graph Nodes: #15664 / PR #15814 (test-environment falsifier), #14182 (cold-provider timeout precedent), #15635 (separate vessel-death edge), #14610 / PR #15266 (state-machine origin).

🔬 Depth Floor

Challenge: Does doubling the default merely conceal a dead join, and is console.warn actually observable beyond the worker?

It does not conceal the dead path: the same timer still fires at a finite 20s, still requires the captured generation and opening state, and still routes through the standard commit-or-neither reattach. The log claim is source-backed: src/worker/App.mjs#interceptConsole wraps warn and forwards connected entries as console_log notifications. The helper runs before rollback, and lastDetailVesselFailure retains the state half after the machine settles back at docked.

Rhetorical-Drift Audit (per guide §7.4):

  • Source JSDoc scopes the numbers to the measured seat and preserves boundedness.
  • The PR body no longer collapses the real headed/ticket receipts into L2.
  • PMV is framed as repeat validation, not an unmet close-target AC.
  • No universal browser, host, or timing guarantee is claimed.

Findings: No blocking rhetorical or behavioral drift remains. During review I corrected the Evidence declaration in place under the maintainer-polish path; no author-owned design changed.

🧠 Graph Ingestion Notes

  • [RETROSPECTIVE]: A correct admission guard became a false-negative source when its default represented healthy boot time but not the observed cold-seat tail. The durable repair is calibration plus an explicit failure witness, not unbounded waiting.
  • [TOOLING_GAP]: CI can deterministically cover the state-machine seam but cannot manufacture a genuinely loaded browser seat. The existing live receipt closes the ticket; the retained PMV repeats the observation on plain dev after #15814.

N/A Audits — 📑 📡 🔗

  • 📑 Contract Completeness: N/A — internal non-reactive class config plus protected helper; no consumed public API or Contract Ledger surface changes.
  • 📡 OpenAPI Description: N/A — no MCP/OpenAPI surface.
  • 🔗 Skill/Convention Propagation: N/A — no reusable workflow convention introduced.
  • App-work contract: Pass — no store/model data-path, Provider placement, or styling mutation; the touched class config follows the Base config contract.

🎯 Close-Target Audit

  • Close-target identified: #15648 only.
  • Target is a leaf bug, not an epic.
  • AC1: ticket evidence records the same seat flapping at 10s and surviving at 20s; this head installs 20s as the default.
  • AC2: the dead-connect timer remains finite and its rollback witness passes.
  • AC3: failed-timeout is retained in state and emitted to the bridged warning stream; failed-blocked receives the same visibility.
  • AC4: the canonical spec distinguishes immediate legitimate connect (timer cleared, windowed) from an injected 20ms non-connect (timeout, rollback, witness).
  • No magic-keyword residual remains.

🪜 Evidence Audit

  • Corrected declaration: L2 in CI (unit seam) + L3 live (headed app/ticket same-seat receipts) → L3 required.
  • The close target's observable loaded-seat behavior has a live receipt.
  • The plain-dev rerun after #15814 and another loaded-seat capture are non-closing PMV, not residual ACs.
  • Review language does not promote the unit seam beyond what it proves.

🧪 Test-Evidence & Location Audit

  • All 11 required checks are green at exact head 27387c4545aa8232111c61fa71c8fa9c4df2dacd.
  • Reviewer reran npm run test-unit -- test/playwright/unit/apps/agentos/view/fleet/fleetCockpitPopOut.spec.mjs at the fetched head: 13/13 passed.
  • The warning captures use try/finally and restore the exact prior console.warn, protecting the shared worker process.
  • Production timing is not slept: the timeout witness injects 20ms at instance creation.
  • Test placement is canonical under test/playwright/unit/apps/agentos/view/fleet/.
  • Commit subject carries #15648; the two-file diff is clean and cohesive.

Findings: Exact-head behavior, isolation, and placement pass.

📋 Required Actions

No required actions. The Evidence line was corrected directly during review; the two PMV bullets remain useful non-closing validation.
