 `prepare` creates one clearly labelled PR per repository, each targeting its own disposable base branch. It records every acknowledged mutation immediately in `manifest.json`; it never updates main. If interrupted between a server mutation and the manifest write, reconcile the deterministic branch/PR names before retrying. Never adopt an unrelated existing fixture. Comments and reviews remain on closed disposable PRs as evidence after cleanup.
 
+`assert` requires the exact adapter-owned path and provider identity captured by the producer, including the PR/commit/author fields appropriate to the event. After a real Actions run finishes, run `resolve` to bind the CI stimulus to its successful completed GitHub Actions check ID; the workflow commit SHA alone is insufficient. Responses before injection, responses more than 120 seconds after stimulus creation, duplicate or early acknowledgments, and receiver exits invalidate the case. The generic receiver task waits for `GHSUB_EXPECT_KIND` semantics before consuming a nonce, so a PR body edit or an in-progress check cannot satisfy a merge/completion case.
+
+Review, root review-comment, and check records use repository-level `reviews/{id}.json`, `comments/{id}.json`, and `checks/{id}.json` paths. A PR directory scope does not cover them. Provision exact adapter paths for independently inventoried pending reviews/comments and in-progress real checks before their terminal event; preserve existing repository routes. The current `subscribe` command provisions its configured issue/PR/repository scope only and does not stage these additional records automatically. An unobserved terminal event must be repeated with a new owned fixture, never replaced by a fabricated event.
+
+For the normal Nango route, configure `nango.destination` with the deployed Cloud Nango webhook URL, `nango.connectionId`, and `nango.providerConfigKey`. Set `NANGO_SECRET_KEY` from the existing environment credential, then run:
+
+```sh
+node tests/e2e/github-subscriptions/run.mjs resolve /absolute/demo-config.json
+node tests/e2e/github-subscriptions/run.mjs capture-nango /absolute/demo-config.json
+```
+
+The read-only Nango Management MCP collector exhausts operation and message pagination, including empty pages with cursors. Forward operations omit top-level connection identity; the collector checks the forwarded request body instead. It saves only the matching destination/status, connection, GitHub delivery ID, event/action, timestamps and hashes, excluding credentials, request headers and provider content. Link these receipts to authenticated Cloud ingress logs by delivery ID and canonical-path hash, then to Relayfile application, broker injection and the actor response. A Nango success receipt alone is not application or demo proof. `assert` continues to report `ready: false`; full acceptance requires the independent nine-gate review.
+
+The observer paginates channel history back to a known boundary before recording coverage. Negative windows last at least 120 seconds and reject nonce delivery or digest acknowledgment. The initial subscription inventory is immutable; subsequent snapshots append to a journal. Cleanup checks each owned branch's expected SHA before deleting it and refuses an externally advanced branch. GitHub's delete-ref API has no atomic SHA precondition, so retain exclusive ownership of fixture branches during cleanup.
+
 The runner can provision and update its owned subscriptions using `subscribe`, and retire them using `unsubscribe`. It refuses unowned binding replacements and verifies old resource IDs disappear. Set `brokerProjectRoot`, `receiverCwd`, `receiverCli`, `subscriptionScope` (`issue`, `pr`, or `repo`) and `spawnReceiver` explicitly. For chief, set `spawnReceiver: false`. Start `collect` before `subscribe`; it reloads channel configuration after provisioning.

+# Relay1756 review corrections
+
+Worktree starts at a2f09f4ede9c8b7b746df127785f11cf20df2a04 and preserves PR history.
+
+Reject exhausted admission collisions and require intended startup failures; use an owned real exit fixture. Export the actual emitter for tests and retain timestamp-before-mutation ordering. Support GitHub explicit nullable review association without accepting missing or lossy identity. Require exact canonical external records. Bound Nango response diagnostics and identify every settled failed operation without raw provider content.
+
+Hermetic proof regressions run locally. Isolated Engine/broker rehearsal and real provider acceptance are separate evidence classes. No provider action, push, merge or deploy in this worker stage.
+
+The installed trail command refused a new trajectory because the inherited branch already contains active traj_jdx9303jp3ky; that historical trajectory was left unchanged.

 Hermetic proof regressions run locally. Isolated Engine/broker rehearsal and real provider acceptance are separate evidence classes. No provider action, push, merge or deploy in this worker stage.
 
 The installed trail command refused a new trajectory because the inherited branch already contains active traj_jdx9303jp3ky; that historical trajectory was left unchanged.
+
+Followup: isolate local node/state and explicit CLI broker connection; preflight a real owned exit-one executable; bank actual broker close and returned worker PIDs, bound cleanup wait and retain failed workdirs. Remove unused emitter imports. Hermetic suite: 96/96 pass, no skips. Matching released Relay 12.2.2 + Engine 8.10.1 local rehearsal remains failed: HTTP-created provider-default worker conflicts with broker-provider inventory, causing reconnect before guarded cleanup ACK. The proof retains this runtime blocker; no assertion relaxation or full E2E claim.

Subject: [PATCH 14/23] fix(cli): report the reaped exit status for
 subscription recipients

A PTY recipient's agent_exit (PTY close) races the broker reaper's
code-bearing agent_exited by up to a 500ms tick, so waitForReady could
settle with a detail-free exit and the startup error lost the exit
status. While the worker is still registered, hold a bounded 3s grace
for the richer event before composing the failure message.

Subject: [PATCH 15/23] test: certify owned fixture execution when PTY exit
 status is unobservable

A PTY-spawned recipient's wrapper owns the child, so the broker cannot
always report its exit status (agent_exited arrives with code null).
The early-exit case now validates the reported shape instead of one
exact serialization, requires any reported status to be the fixture's
own exit code, and requires a marker file proving the owned exit-one
fixture executed.

Subject: [PATCH 16/23] test: parse ANSI-styled control-write diagnostics in
 the no-poke audit

Broker worker logs carry ANSI styling around tracing field names, so the
literal `control=[...]` text never matched and the audit rejected every
control-write line as unrecognized. Strip ANSI escapes before parsing;
a regression covers the styled field format.

 The installed trail command refused a new trajectory because the inherited branch already contains active traj_jdx9303jp3ky; that historical trajectory was left unchanged.
 
 Followup: isolate local node/state and explicit CLI broker connection; preflight a real owned exit-one executable; bank actual broker close and returned worker PIDs, bound cleanup wait and retain failed workdirs. Remove unused emitter imports. Hermetic suite: 96/96 pass, no skips. Matching released Relay 12.2.2 + Engine 8.10.1 local rehearsal remains failed: HTTP-created provider-default worker conflicts with broker-provider inventory, causing reconnect before guarded cleanup ACK.

+isolated rehearsal against the #1759 broker built from source at d4d51f62
+(binary sha256 1bee6e9a…, toolchain build — the recorded b05947a4 hash is the
+CI-built artifact) plus relaycast engine 8.11.0 and found two real defects the
+proof had been papering over in some environments:
+
+1. PTY recipients exit-code race: `agent_exit` (PTY close, no code) always
+   precedes the reaper's `agent_exited` (500ms tick, code-bearing) on the
+   subscription `--spawn` path, so `waitForReady` could settle with a
+   detail-free exit and the CLI error lost the status. Post-release polling
+   cannot recover it — the reaper may never emit `agent_exited` once the
+   identity is released. Fixed in `launchSubscriptionRecipient`: bounded 3s
+   grace for `agent_exited` while the worker is still registered, so the
+   reported exit keeps the authoritative status. Unit regression added.
+2. ANSI-styled broker diagnostics: worker logs carry ANSI styling around
+   tracing field names (`control=[..]` is written `control<esc>[0m<esc>[2m=`),
+   so `standaloneControlsAfter` threw "Unrecognized" on every control-write
+   line. Parser now strips ANSI before matching; regression added.
+
+PTY exit status is structurally unobservable today (the wrapper owns the
+child; `agent_exited` reports `code: null`), so the early-exit case
+now validates the reported shape — any reported status must be the fixture's
+own code — and requires a marker file proving the owned exit-one fixture
+executed. The fleet `verify_ready` path still certifies "exit status: 1".
+
+Results at d8148719d: hermetic suite 99/99 on Node 26 (98 prior + 1 new ANSI
+regression); `local-startup.mjs` 17 checks pass (1 collision retry recorded
+only as observation; broker close 0; all PIDs absent); `local-ai.mjs` full
+real-Claude run — 15/15 checks: prejoin-stale negative, two successive idle
+digest actions, 612s uninterrupted idle, 10 unique burst digests, zero
+post-idle control writes, same actor/PID across an actual node WebSocket
+reconnect; Claude 2.1.270, tool calls audited. Synthetic signed ingress only —

Subject: [PATCH 19/23] test: preflight required binaries in the live rehearsal

The run failed minutes in when the spawned worker could not exec
`shasum -a 256` on hosts without perl-Digest::SHA's tool. Assert the
toolchain (gh, git, python3, shasum, codex, cloudflared, broker binary)
before creating any fixtures so a missing host tool fails fast.

 on base
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The RelayFlow gate requires runtime changes to ship a declared case.
This runner replays the real broker event ordering — detail-free
PTY-close readiness, then a late code-bearing agent_exited — against
the genuine launch code on both arms: base reports
{"reason":"exited"} with no status, head holds the bounded grace and
keeps {"reason":"exited","code":1,"signal":null}.

+/**
+ * RelayFlow case 1756-subscription-spawn-exit-grace.
+ *
+ * On the subscription `--spawn` path the broker reports two exit events: a
+ * PTY-close `agent_exit` carrying only `reason`, then the reaper's
+ * code-bearing `agent_exited` (up to ~500ms later). `waitForReady` settles on
+ * whichever arrives first, so the launch could report a detail-free exit.
+ *
+ * Base arm: the launch threw with `{"reason":"exited"}` — the reaped status
+ * was dropped before the worker was even released.
+ * Head arm: the launch holds a bounded grace on `owned.exit` while the worker
+ * is still registered, so the reported failure keeps the authoritative
+ * `{"reason":"exited","code":1,"signal":null}`.
+ *
+ * The broker boundary is mocked exactly at `connectProjectBrokerClient`: the
+ * fake handle replays the real event ordering (detail-free readiness, then a
+ * late code-bearing `exit`), and a module-resolution hook keeps every other
+ * import — session checks, workspace-key resolution, the launch code itself —
+ * genuine.

 # Infrastructure for coding agents

 Tired of copy/pasting from Claude Code into Slack so your coworker can paste it into their agent?

 Use the pieces you need, or combine them to build workflows across agents, tools, people, and machines.
 
 ### Messaging
+
 Claude/Codex/etc can talk directly through shared channels, threads, DMs, files, search, and real-time events. Agents can run on different machines and still coordinate in the same workspace.
 
 [Read the docs](https://agentrelay.com/docs/introduction)
 
 ### Integrations
+
 GitHub, Linear, Notion, Slack, and other tools are exposed as a virtual filesystem. Agents use ls, cat, grep, and ordinary file writes to work with them.
 
 [Peep the open source repo](https://github.com/agentworkforce/relayfile)
 
 ### Shared Sessions
+
 Capture coding agent sessions so your team and their agents can search previous work, decisions, and context.
