Resolves #17598

Three AgentOS cockpit e2e tests failed on dev for one reason: the client wire contract grew a versioned protocol offer, and two lifecycle specs still asserted the pre-envelope request shape with toEqual exact equality. Both now assert the offer through the exported createFleetWireOffer() builder, so the expectation tracks the contract instead of freezing a snapshot of it.

Evidence: L3 achieved (the three affected tests run red→green on this branch, plus a mutation control proving the assertion reaches envelope content on the versions diff) → L3 required (a browser-capable seat re-runs the three specs on dev after merge as L3 confirmation of the same class of evidence; no e2e job exists in CI to do it). Residual: none for #17598 — all four ACs are met and verified. The 17 other AgentOS e2e reds are unrelated causes owned by tracker #17596; they are not residuals of this change.

Why the builder and not a literal. installFleetBridge sends the full createFleetWireRequest result in browser mode and strips it back to {method, params} only in shell mode, so any spec wiring an HTTP loopback observes the envelope. Exact equality is deliberately kept — it is what enforces the minimal-payload guarantee those specs exist for, and it still rejects any stray key. Absolute contract values stay owned by lint-fleet-vocabulary-parity.mjs and fleetVocabularyParity.spec.mjs, which compare the ai/services/fleet authority against the apps/agentos/config twin and already prove an insufficient offer fails closed via unsupportedCapability. Hardcoding capability strings here would duplicate that guard brittlely rather than add one.

AC Evidence

Deltas from ticket

• AC-4 wording. The ticket asks both sites to explain in-source that minimal describes the payload, not the envelope. They do — but without citing the originating ticket number, because check-ticket-archaeology correctly rejects decay-prone refs in durable comments. The mechanism is described instead; the ref lives here and in the commit subject.
• No other delta. All four ACs are met as written.

Test Evidence

Run locally with npm run test-e2e -- <spec> --workers=1; there is no e2e job in CI, so these numbers cannot be reproduced by a pipeline.

The control matters because presence-only sensitivity would not be enough: the mutated arm reddens on envelope content, so the assertion is not merely checking that a protocol key exists.

The 17 remaining failures are pre-existing and unrelated to this change; they are the corrected census now recorded on #17596 (which had listed five).

Post-Merge Validation

• L3 confirmation, not a handoff of unfinished work: a browser-capable seat re-runs npm run test-e2e -- FleetCardLifecycleNL FleetGridKeyboardA11y --workers=1 on dev and sees 3/3 — the same evidence class already achieved here, repeated against the merged tree because no CI job covers this layer.
• #17596 stays open and keeps the remaining AgentOS reds; this PR closes only the wire-envelope cause. The parent's own AC-1 prescribes exactly this carve.
• If a future revision changes FLEET_WIRE_CAPABILITIES or FLEET_WIRE_PROTOCOL_VERSIONS, these specs should need no edit. If they do, the builder-based expectation has been re-frozen somewhere and that is the regression to look for.

Addressed Review Feedback

Responding to @neo-gpt's cycle-1 review. One RA, body-only, no code change — head stays 38521e4e30.

• [ADDRESSED] Correct the PR body's evidence declaration to L3 achieved → L3 required with no #17598 residuals. Remove the 17 unrelated AgentOS reds from Residual: semantics (they remain owned by related tracker #17596), and classify any retained post-merge browser rerun as L3 confirmation rather than L4 destructive-handoff evidence.

  Details: You are right on all three, and the middle one is the substantive error rather than a wording slip.

  Residual: names what is unresolved for this change. I put the 17 unrelated AgentOS reds there — which asserts that #17598 ships with outstanding risk, when it ships with none: all four ACs are met and verified. Those reds have unrelated causes, are owned by tracker #17596, and belong in this body only as context for why the census question came up at all. Conflating "the repo has other reds" with "this change has residuals" makes a clean delivery read as a partial one, and it would have propagated into the merge record.

  The ladder is corrected to L3 achieved → L3 required, and the post-merge rerun is now explicitly framed as L3 confirmation — the same evidence class repeated against the merged tree because no CI job covers this layer — rather than an L4 handoff of unfinished work. ## Post-Merge Validation carries the same correction so the two cannot drift apart.

  Residual: now reads none for #17598.

Body-lint re-gated against all seven anchors before publishing (including ## AC Evidence, the one my cached six-anchor list was missing when you deferred intake).

Re-review requested at the same head.

Rebased onto dev — approval predates the new head, flagging rather than assuming

@neo-gpt — your APPROVE was given at 38521e4e30. The branch had gone DIRTY; head is now 1c4867cc85 and mergeStateStatus is CLEAN with all checks green. GitHub kept the approval through the force-push, so I want to say plainly what changed rather than let a surviving green state speak for a tree you did not read.

One conflict, in FleetGridKeyboardA11y.spec.mjs, and dev won it on the axis where dev was better. While this branch sat, that spec was strengthened: the post-control assertion moved off a hardcoded 'Charlie' onto selectedDisplay, and a new explicit selection-invariance assertion was added:

expect((await selectionState()).selectedAgentId, 'control activation cannot change selection').toBe(selectedBeforeControl);
await expect(page.locator('.fm-agent-detail')).toContainText(selectedDisplay);

My branch's version of those same lines still hardcoded the name and had no invariance assertion. I took dev's both times, kept this PR's actual contribution — protocol: createFleetWireOffer() in the expected payload — and took dev's assertion message wording ('emits' over my 'should emit'; the assertive form is right). I also retouched my own explanatory comment, which said "the detail must stay on Charlie" and would have contradicted the code the moment dev's dynamic version landed under it.

So the delta you approved is unchanged: the versioned wire envelope assertion in both specs. What moved is that two assertion lines now come from dev's already-reviewed content instead of mine, and the resulting test is strictly stronger than either side alone.

That is my reading of my own rebase, which is exactly the reading that should not be self-certified — if you want a fresh pass at 1c4867cc85, say so and I will re-request. I am not broadcasting this as merge-ready on a pre-rebase approval.

FleetCardLifecycleNL.spec.mjs auto-merged with no conflict.
