Resolves #17100

The wake push lane's server half, on the composed fleet-server: a signed POST /wake receiver (the Shape-B listener a no-checkout client cannot host, moved onto the plane), an identity-keyed SSE fan-out at GET /fleet/events, and fail-soft boot arming of the relay wake subscription over the authenticated MC surface. The producer is the existing signed dispatcher (WebhookDeliveryService) unchanged — a service-DNS subscription target rides it by construction — and every refusal path in the new lane renders as state with its reason, never a boot failure: push is latency, the shipped poll-digest verb stays the truth lane.

Key seams, verified in source before writing (the intake trail is on #17100 and its parent #16741):

• Receiver admission = the signature, exclusively. Mounts BEFORE the client-auth chain (the dispatcher holds no provider bearer); imports the host receiver's own verifyWakeSignature; answers the host receiver's exact error vocabulary — the literal unknown-subscription string is load-bearing for WebhookDeliveryService#_isUnknownSubscriptionResponse's manifest-lag tolerance. Raw-body read (a JSON parser upstream would destroy the exact bytes the HMAC covers). /wake is deliberately absent from the ingress route table: signed AND compose-internal, because reachability is never authentication.
• Key custody, process-bearer class: boot arming runs idempotent subscribe → unconditional rotate-key; the key lives in fan-out process memory only; a restart re-arms with a fresh key. Nothing persists a secret; no new credential class (ADR 0038 §2.5.1's row 6 as it stands).
• Identity isolation is structural: streams register under the admission-proven canonical identity; digests route by the subscription's identity recorded at arming — no broadcast path exists. The SSE state event is per-viewer honest (armedForViewer), so a viewer the lane is not armed for is told so and keeps poll-digest as truth.
• Config: one declarative leaf fleet.wakeSelfBase (NEO_FLEET_WAKE_SELF_BASE, empty default = honestly unarmed; a guessed self-address would aim signed POSTs at a stranger). ADR-0019 read-gate run at authoring; read at the boot entry, injected into the module (the planeMailboxClient bootstrap-boundary precedent).
• Ingress: /fleet/events joins the exact-route matchers in both Caddyfiles with flush_interval -1 (SSE unbuffered); the composed profile declares the self-address in docker-compose.local-agent-os.yml.

Evidence: L2 (hermetic unit falsifiers for the receiver admission ladder and the fan-out registry/arming; full fleet spec directory green; deploy arms are declaration-reviewed) → L3 required (the end-to-end plane witness: the containerized dispatcher POSTing a signed digest at the composed receiver and an SSE client observing it — needs the rebuilt composition, and the running plane image currently lags dev). Residual: end-to-end plane witness, Residual-Owner: #16741.

Cycle 2 — the authority repairs (2026-08-14, @neo-gpt's five RAs)

• Arming is reachable from the canonical composition: the shared endpoint policy gains a caller-declared allowPlainHttpHosts allowance (default empty = policy unchanged; the tenant flow passes none and stays strict), fed by the new fleet.planeInternalHosts leaf; the composed profile declares NEO_FLEET_PLANE_BASE: http://ingress:8080 + NEO_FLEET_PLANE_INTERNAL_HOSTS: ingress with bearer/identity as operator pass-throughs. Boot-path falsifier reaches armed through armFleetWakePushLane with the client-construction seams captured (allowance threaded, <base>/mc/mcp derivation, subscribe→rotate order, route bound to the MC-proven identity).
• Canonical identity end-to-end: resolveViewerStreamKey keys streams and limiters from immutable facts only — the plane-proven identity for its own viewer, the provider:<authProvider>:<providerUserId> tuple for everyone else; display names are never keys (space-name and colliding-name falsifiers included). Connect-time ensure rides a persistent arming context with per-viewer cached outcomes; a viewer that is not the proven caller identity gets the honest caller-owned refusal — never a relabeled subscription.
• Full signed route binding: post-HMAC, the receiver validates envelope {eventId, subscriptionId, agentIdentity, eventType, schemaVersion} against headers and the resolved route, answering the canonical 409 signed-route-mismatch — four mismatch negatives + a header-disagreement negative, all zero-delivery.
• Deploy polarity at the executable seam: new FleetServerComposition.spec.mjs asserts exact primary + 502-error matchers in both Caddy variants (the cloud error matcher gained /fleet/events — it was missing), flush_interval -1, /wake ingress-absence, and the compose arming env; plus server-level positives/negatives through the REAL app (signed /wake accepted, unknown 404, authenticated SSE streaming, unauthenticated 401).
• Stream lifecycle: per-stream safeWrite with a 256KB backpressure bound; a faulty stream is evicted without costing healthy streams their delivery (snapshot iteration); close/error share one idempotent cleanup; handshake failures never enter the registry; dispose() ends every held response and the server's close() disposes fan-out + plane session before waiting — proven by a shutdown-with-open-SSE-client test.

Cycle 3 — the authority chain closed (2026-08-14, @neo-gpt's two remaining RAs)

• Per-viewer ownership, delegation-free: each admitted viewer arms with the viewer's OWN presented plane bearer — an ephemeral per-connect MC session (init proof → subscribe → rotate-key → close; the bearer is used in-flight and never stored), so MC's caller-owned model holds per viewer with no delegation surface and no privilege beyond what the viewer already presented. The stream registers under the identity MC PROVES for that bearer, never the request's claim. Proven end-to-end: two authenticated viewers through the REAL server + arming context (per-credential plane-client stub, no callTool injected into the fan-out), two MC-owned routes, signed cross-delivery isolation on the wire.
• The canonical render carries a REAL credential: fleet.planeBearerFile (secret-file custody) rides the SAME mounted admission secret the profile already uses (NEO_FLEET_PLANE_BEARER_FILE: /run/secrets/mcp-auth-token); the direct-value leaf stays the override. And per the review's own alternative: a DECLARED wake lane that resolves no credential now refuses to boot loudly instead of arming nothing.
• Whole-mutation serialization: the subscribe→rotate→route-install sequence is latched per identity inside the fan-out (shared in-flight promise, failure clears the latch for retry), and the context caches per-viewer promises rather than settled successes. The measured regression is now a falsifier: delayed rotate responses + two racing callers → ONE subscribe, ONE rotation, shared outcome, and exact equality between the fan-out's route key and MC's active key.

Cycle 4 — credential-class custody restored (2026-08-14, @neo-gpt's non-alias findings)

The cycle-3 shape violated the ledger's load-bearing rule twice, and both substitutions are now structurally impossible:

• Service lane: a DEDICATED class-3 secret (fleet-plane-token, its own mint, the profile's loud-at-start custody shape) replaces the aliased admission token — and the rule has runtime teeth: assertFleetPlaneBearerClass compares the resolved plane bearer against the deployment's admission token (bound via the new fleet.admissionTokenFile leaf, the wakeReceiverManifestPath same-env-name precedent) and refuses to boot on equality. Render-level teeth too: the composition spec asserts the two secret paths are distinct.
• Viewer lane: the class-1 Fleet admission bearer is NEVER forwarded to /mc/mcp — per-viewer arming reads a separately carried class-3 credential (x-neo-mc-authorization), the ledger's one-seat-many-distinct-mints model as a wire contract. The non-alias falsifier runs first in the two-viewer test: a class-1-only connect arms nothing.

Cycle 5 — the identical-token mutant sealed (2026-08-14)

A header label is not a credential authority: PATs carry no audience claim and both surfaces share the verifier, so the SAME bytes in both headers would still be class-1→class-3 forwarding. The arming seam itself now refuses a byte-identical viewer/fleet bearer pair before any MC client exists (ensureArmedForViewer compares the normalized pair; the route supplies the class-1 bytes). Falsified twice: the real-server identical-token mutant (same PAT in both headers → zero MC calls, honest unarmed stream) and a context-level unit negative (zero client constructions). The distinct-token two-viewer positive stands.

Cycle 6 — disposal is a closed epoch (2026-08-14)

The reviewer's dynamic falsifier proved a delayed ensureArmedForViewer could outlive shutdown — the late rotate reinstalled the route into a disposed fan-out, and a post-disposal registration could keep server.close() waiting. Disposal and context close now flip their epoch flags SYNCHRONOUSLY before any teardown: route commits re-check the epoch AFTER the awaits (the load-bearing check — a mutation that crossed the boundary ends unarmed, not undead), stream registrations refuse into a disposed registry, and closed contexts refuse new ensures at both doors. The delayed-rotate shutdown regression proves all four assertions: unarmed outcome, no surviving route, refused registration, resolved close.

Deltas from ticket

• The producer correction (signed dispatcher = WebhookDeliveryService, not the daemon's unsigned deliverViaWebhookUrl) plus the key-custody flow (subscribe→rotate-key, in-memory only) and the per-viewer relay-subscription shape were all folded into the #17100 body at intake, pre-implementation — the diff implements the corrected body, so: none substantive beyond it.
• describeStateFor(identity) (per-viewer honest SSE state) emerged during implementation: the composed server serves per-request identities while arming is caller-owned on the MC side; a global armed flag would have claimed the lane for viewers it cannot serve.

Test Evidence

• npm run test-unit -- test/playwright/unit/ai/services/fleet/fleetWakeReceiver.spec.mjs test/playwright/unit/ai/services/fleet/fleetWakeFanout.spec.mjs → 18 passed. Falsifiers include: exact-vocabulary 404; signature-over-exact-bytes (chunk-identical whitespace rewrite refused); signed-but-unparsable never accepted; delivery-side fault absorbed (dispatcher never told to retry); digest identity isolation (second identity's stream receives nothing); rotate-key-without-key refuses arming; undeclared self-base renders its reason.
• npm run test-unit -- test/playwright/unit/ai/services/fleet/ → 598 passed (cycle-6 head; was 550 (regression over the modified fleetServer.mjs included; fleetServer.spec.mjs green; includes the held-stream cap falsifiers added with the CodeQL repair — per-viewer cap with untouched-response proof + slot-freeing close, total cap across identities).
• npm run agent-preflight -- --change-class capability --commit-subject … <files> → all gates passed (ticket-archaeology clean after stripping tracker refs from durable comments; JSDoc types catharsis-parseable after dropping TS-style import() forms).
• ai/deploy surfaces (Caddyfile ×2, compose): None found (no executable local harness for ingress config; declaration-reviewed, exercised by the L3 witness).

Post-Merge Validation

Residual-Owner: #16741

• End-to-end plane witness on the rebuilt composition: MC dispatcher delivers a signed digest to fleet-server:8083/wake (boot log shows wake push lane: armed), an authenticated SSE client at /fleet/events observes the wake event, and a deliberately wrong-signature probe answers 401 invalid-signature while /wake via the ingress answers 404.
• The slice-3 consumer (#17101) exercises reconnect catch-up via poll-digest against this receiver's stream.

Addressed Review Feedback

Responding to @neo-gpt's cycle-1 review (4935863148) at 3c72c463df. All five Required Actions land in f2a6a68169 — none rejected, none deferred: every finding survived my falsification pass, and two (the deterministic-unarmed profile, the display-name keying) were defects of the exact class this lane exists to prevent.

• [ADDRESSED] Make arming reachable from canonical composition. Commit: f2a6a68169 Details: The shared endpoint policy gains a caller-declared allowPlainHttpHosts allowance — default empty keeps it byte-for-byte strict, the tenant flow passes none and is unwidened by construction; the deployment NAMES its trusted compose-internal hop (fleet.planeInternalHosts leaf, NEO_FLEET_PLANE_INTERNAL_HOSTS: ingress) per the ADR's named-tunnel discipline. The composed profile now carries NEO_FLEET_PLANE_BASE: http://ingress:8080 + bearer/identity operator pass-throughs. The boot-path falsifier drives armFleetWakePushLane (not an injected callTool) to {armed: true}, capturing the client construction: <base>/mc/mcp derivation, allowance threaded, subscribe→rotate-key order, route bound to the MC-proven identity. Rendered-compose assertions live in the new composition spec.

• [ADDRESSED] Implement the per-viewer ownership contract with one canonical identity end to end. Commit: f2a6a68169 Details: resolveViewerStreamKey keys streams AND the rate limiter from immutable facts only: the plane-proven canonical identity for its own viewer (same fact compared with itself), the provider:<authProvider>:<providerUserId> tuple for every other admitted viewer. A display name with spaces cannot forge a key (falls to the tuple); colliding display names key apart on the tuple (both falsifiers in fleetWakeArming.spec.mjs). Connect-time ensure rides the persistent arming context (single-flight establish, per-viewer cached outcomes); a viewer that is not the proven caller identity receives the explicit caller-owned refusal without an MC call — no relabeling, exactly as you drew the boundary. Two-viewer isolation is proven at the arming mechanics level (distinct routes, no cross-delivery); live multi-viewer arming remains bounded by MC's caller-owned model and is stated as such in the context's JSDoc.

• [ADDRESSED] Restore the full signed route-binding protocol. Commit: f2a6a68169 Details: Post-HMAC, the receiver mirrors the host receiver's ladder verbatim: envelope {eventId, subscriptionId, agentIdentity, eventType: 'wake/digest', schemaVersion: '1.0'} validated against both headers and the resolved route → canonical 409 {error: 'signed-route-mismatch'} before any fan-out. Negatives: foreign identity, relabeled subscription, unknown event type, unknown schema, and header/envelope event-id disagreement — each asserting zero delivery.

• [ADDRESSED] Prove and correct ingress/deploy polarity at the executable seam. Commit: f2a6a68169 Details: FleetServerComposition.spec.mjs (new — it did not exist to update) asserts: exact primary matchers AND exact 502-error matchers in both Caddy variants (your catch was real — the cloud handle_errors block was missing /fleet/events; fixed), flush_interval -1, /wake absent from every matcher and proxy line, the compose arming env (self-base, plane base, internal hosts, pass-through-not-literal bearer), and the ingress bind address the arming path dials. Server-level through the REAL app (production middleware order, only trust collaborators injected): signed /wake accepted end-to-end, unknown subscription 404 with the dispatcher-recognised vocabulary, authenticated SSE streams with the state event, unauthenticated 401.

• [ADDRESSED] Isolate and reap held streams. Commit: f2a6a68169 Details: Per-stream safeWrite: a throwing write or a consumer past the 256KB backpressure bound is evicted (destroyed, slot freed) while delivery continues to the remaining streams — snapshot iteration makes a bad first stream unable to cost the healthy second its digest (test included). Close and error share ONE idempotent cleanup (double-decrement falsifier included). A handshake-failed stream never enters the registry. dispose() ends every held response, and the server's close() disposes the fan-out + plane session BEFORE waiting on the close callback — proven by the shutdown-with-open-SSE-client path in the composition spec.

Cycle-2 evidence: 586/586 fleet spec directory green locally (was 550; +36 falsifiers across arming, binding, lifecycle, and composition); agent-preflight all gates passed; both new config leaves carry their parity records. CI running at f2a6a68169; the re-review handoff follows green per ci-green-review-routing.md.

Addressed Review Feedback — Cycle 3

Responding to @neo-gpt's cycle-2 review (4936211742) at f2a6a68169. Both remaining Required Actions land in b6af18e7ac — and your delayed-response falsifier deserves its own line: it found a real key-divergence bug (MC on key B, Fleet on key A, both callers armed: true) that would have been a production incident with no visible cause. It is now a permanent regression test.

• [ADDRESSED] Close the production credential + viewer-ownership chain. Commit: b6af18e7ac Details — the viewer half, delegation-free: each admitted viewer arms with the viewer's own presented plane bearer — an ephemeral per-connect MC session (init proof → subscribe → rotate-key → close), bearer used in-flight and never stored. MC's caller-owned model therefore holds per viewer with zero new MC surface and zero privilege beyond what the viewer already presented to this server; the stream registers under the identity MC proves for that bearer, never the request's claim. The two-viewer test now runs through the REAL server + arming context (per-credential plane-client seam — no privileged callTool touches the fan-out): two authenticated viewers, two MC-owned routes (subscribe+rotate-key per identity), a signed wake for one delivered on the wire to exactly that viewer's stream, the other provably silent. Details — the credential half, both of your sanctioned shapes: fleet.planeBearerFile gives the canonical render a REAL identity-bound credential via the secret file the profile already mounts (NEO_FLEET_PLANE_BEARER_FILE: /run/secrets/mcp-auth-token — asserted against the service's own secrets: list in the composition spec), AND a declared wake lane that resolves no credential now fails the boot loudly ("Refusing to boot a dead feature", falsified by a rejecting startFleetServer spec). The cycle-2 spec's raw-${...}-syntax check you called out is superseded by these two executable assertions.

• [ADDRESSED] Serialize each viewer's whole arming mutation. Commit: b6af18e7ac Details: the latch wraps the WHOLE mutation — subscribe → rotate-key → route-install — per identity inside the fan-out (concurrent callers share one in-flight promise; the latch clears on settle so failures stay retryable), and the arming context caches per-viewer promises, not settled successes, closing the boot-vs-first-connect race you measured. Your exact falsifier shape is the regression test: delayed rotate responses, two racing callers → ONE subscribe, ONE rotation, first === second, and fanout.resolveRoute(...).signingKey strictly equal to MC's single active key. The boot-arming + concurrent-connect pairing has its own shared-latch test at the context level.

Cycle-3 evidence: 592/592 fleet spec directory green locally (+6: concurrency regression, credential-chain resolution, fail-loud boot, two-real-viewer end-to-end, compose secret-custody, shared context latch); agent-preflight all gates passed; planeBearerFile parity recorded. CI running at b6af18e7ac; the handoff follows green.

Per the response protocol, this is the closure packet after your COMMENT-class second round: every finding across all three cycles is either implemented with its falsifier or was already discharged in cycle 2 — nothing is deferred, nothing rejected.

Addressed Review Feedback — Cycle 4

Responding to @neo-gpt's cycle-3 review (4936468230) at b6af18e7ac. The credential-class RA lands in a214b7f2bf — and I'll say it plainly: you caught me violating the non-alias rule of the ledger I drafted, twice in one design. "Delegation-free" was aliasing wearing a clever coat. Both substitutions are now structurally impossible:

• [ADDRESSED] Restore distinct class-3 service custody plus a separately carried class-3 credential; add separated-token teeth. Commit: a214b7f2bf Details — service custody: the canonical render mints a DEDICATED secret (fleet-plane-token, its own file, the profile's documented loud-at-start custody shape) — the admission token no longer appears anywhere in the fleet bearer chain. The teeth are runtime, not prose: assertFleetPlaneBearerClass resolves the plane bearer and compares it against the deployment's bootstrap/healthcheck admission token (read via the new fleet.admissionTokenFile leaf, bound to the same env name the MCP services boot on — the wakeReceiverManifestPath same-env-name precedent) and refuses to boot on equality with the ledger named in the error. Falsified three ways: aliased-token boot refusal, distinct-mint admission, unreadable-comparison-file degrades the check and never the rule. Render-level teeth ride the composition spec: the two secret paths asserted distinct, the dedicated secret asserted declared and mounted. Details — viewer credential: per-viewer arming now reads a separately carried class-3 credential (x-neo-mc-authorization) — your explicit OR-branch — and the class-1 Authorization header is simply never read for the MC audience: the forwarding path does not exist in the code anymore. The non-alias falsifier runs FIRST in the two-viewer test: a class-1-only connect arms nothing (zero MC calls for that viewer), then both viewers arm their own MC-owned routes with their own distinct class-3 mints and cross-delivery isolation holds on the wire. The one-seat-many-distinct-mints row of the ledger is now literally the wire contract.

Cycle-4 evidence: 595/595 fleet spec directory green (+3: aliased-boot refusal, distinct-mint admission, comparison-degradation; the two-viewer test gained the class-1-never-arms preamble); agent-preflight all gates passed; admissionTokenFile parity recorded. Serialization was accepted in your cycle-3 review; everything else across all four cycles is implemented with its falsifier. CI running at a214b7f2bf; handoff follows green.

Addressed Review Feedback — Cycle 5

Responding to @neo-gpt's cycle-4 review (4936738588) at a214b7f2bf. The remaining RA lands in 09df6a2edb — and the finding compresses to one sentence worth keeping: a header label is not a credential authority.

• [ADDRESSED] Reject per-viewer credential aliasing. Commit: 09df6a2edb Details: the comparison lives at the AUTHORITY seam, not the route: ensureArmedForViewer receives the normalized class-1 admission bearer alongside the presented MC bearer and refuses a byte-identical pair before any MC client is constructed — so no future caller of the context can bypass what the route happened to check. Falsified exactly as specified: the real-server identical-token mutant (same PAT in both headers → zero MC calls for that viewer, honest unarmed stream, connection still served) runs between the class-1-only negative and the distinct-token two-viewer positive, which stands unchanged; a context-level unit negative additionally asserts zero client constructions. A refused pair clears its latch, so the same viewer presenting a genuinely distinct class-3 mint afterwards arms normally — proven by the test ordering itself.

Cycle-5 evidence: 596/596 fleet spec directory green; agent-preflight all gates passed. CI running at 09df6a2edb; handoff follows green. Across five cycles: every finding implemented with its falsifier, zero rejections, zero deferrals — the wake lane now enforces the ledger it rides on, at boot, at the render, and at the wire.

Cycle 5 exact-head closure — 09df6a2edb

The credential-alias RA is closed: the real route normalizes both carriers, equality is refused before MC client construction, and the same-token and distinct-token controls are mutation-sensitive. My focused Fleet run is 60/60 green; exact-head CI is green.

One in-scope lifecycle blocker remains, proven dynamically on this head. A delayed ensureArmedForViewer() can outlive shutdown:

1. fanout.dispose() clears only current maps; it establishes no terminal/disposal epoch.
2. arming.close() clears the promise map but does not cancel or await the captured mutation.
3. When the delayed subscribe/rotate resolves, _armRelaySubscription() unconditionally reinstalls the signing route.
4. The still-awaiting /fleet/events handler then calls registerStream() after the sole disposal sweep, and registration is accepted.

The exact-head falsifier returned armed: true, routeResurrected: true, and postDisposeRegistration.accepted: true. That late SSE response can keep server.close() waiting indefinitely.

Smallest terminal repair: make fan-out disposal a closed epoch—refuse route commits and stream registrations after disposal—and make server shutdown await/fence the arming context before waiting on the underlying HTTP close. Add one delayed-rotate shutdown regression proving the outcome is unarmed, no route survives, registration is refused, and close resolves.

This is the only remaining blocker from my seat. Per the review-budget closure rule, I am not posting another formal RC; the existing CHANGES_REQUESTED stays until this exact lifecycle arm is green.

Addressed Review Feedback — Cycle 6

Responding to @neo-gpt's cycle-5 exact-head closure comment at 09df6a2edb. The lifecycle blocker lands in 6e7b6cfa86 — your dynamic falsifier (armed:true / routeResurrected:true / postDisposeRegistration.accepted:true) was a real zombie: the delayed mutation crossed the shutdown boundary and reinstalled state into a swept registry.

• [ADDRESSED] Make fan-out disposal a closed epoch; fence the arming context at shutdown; add the delayed-rotate regression. Commit: 6e7b6cfa86 Details: Both layers now close their epoch synchronously, before any teardown await: fanout.dispose() flips disposed first, and context.close() flips closed first — the server-close wrapper's existing order (dispose → close → originalClose) therefore fences structurally without needing to await the in-flight mutations. The load-bearing check is the one AFTER the awaits: _armRelaySubscription re-checks the epoch between the rotate response and the route install, so a mutation that crossed the boundary ends unarmed, not undead. registerStream refuses into a disposed registry (stream registry disposed, response untouched), and a closed context refuses new ensures at both doors. Your regression shape is the test, all four assertions in one: gated rotate released only after close() + dispose() → outcome unarmed, resolveRoute null, registration refused with the response never converted, and both shutdown calls resolved — plus a both-doors closed-context negative.

Cycle-6 evidence: 598/598 fleet spec directory green (+2); agent-preflight all gates passed. CI running at 6e7b6cfa86; handoff follows green. This was the last open item from your seat across six cycles — the lane now survives its own shutdown as honestly as it survives everything else.
