Navigate logical layers of code changes, visualize relationships, and explore their blast radius. 📝 WalkthroughWalkthroughThe broker adds a route-aware delivery seam and a native Codex queue route. It tracks whether delivery was observed, handed over, or left uncertain; persists native routes for restart recovery; and reports unobserved deliveries separately. The change also adds native-session attachment endpoints, migration tooling, and delivery-focused tests. ChangesDelivery seam and write verification

Merge Risk: 🟠 High · up to This change adds native Codex delivery. As written, a Codex agent can receive a false read receipt for a message it never consumed. Later messages to an agent can stall behind an in-doubt delivery. Releasing an agent can leave a same-name worker process running.

When the broker restarts while an externally launched Codex session remains active, this registry is recreated with an empty native_codex_targets map, and the MCP client only calls the attach endpoint during an explicit register_agent invocation. Consequently the still-running, remotely registered agent disappears from delivery discovery and new messages report a missing recipient until the user manually registers again. Persist enough attachment metadata to rebuild these targets, or add an automatic authenticated reattach handshake on MCP/broker reconnection.

After this inserts a native target, both the HTTP and fleet spawn paths still reject duplicates using only has_worker, and spawn_with_generation likewise checks only the broker-owned workers map. A spawn using the attached agent's name can therefore create a second target with the same identity; ordinary delivery then prefers the old Codex queue route over the newly spawned worker, and release detaches the native entry and returns without stopping the child. Treat has_delivery_target as the name-uniqueness check for every spawn path.

For a long-lived Codex thread with a large rollout, every pending native delivery causes a full-file allocation and read here on each one-second maintenance poll, for up to the two-minute settlement window. Because maintenance settles due deliveries sequentially on the broker actor, several pending messages multiply the same JSONL I/O and delay unrelated API, fleet, and worker events. Retain scan offsets or read each thread's appended tail once per maintenance pass instead.

🔴 Fleet replay duplicates uncertain messages
After an in-doubt delivery leaves pending custody, recover_unacknowledged_replay surfaces its replay despite the recorded seen marker. The drain creates a fresh delivery ID, bypassing the seam's original receipt and injecting the message again.
Learn more
Fleet delivery uses an engine-assigned delivery ID, but the drain path in try_inject_pending_relay_message generates a new ID each time it surfaces a frame. An in-doubt delivery is moved from the pending map to a dead letter by emit_delivery_attempt_outcome. Once custody is gone, recover_unacknowledged_replay overrides Duplicate and surfaces that same frame again. The seam only remembers the first generated ID, so it accepts the second write. This also applies after a successful native handoff times out while waiting for consumption.
Example: Frame msg-7 queues once to Codex as del_A, then settlement expires and removes del_A from pending. Relaycast retries msg-7; recovery creates del_B, and Codex queues the same message a second time.
Recommended fix: Preserve the engine delivery ID on every fleet surfacing attempt, and consult retained in-doubt/route state before treating a duplicate without pending custody as safe to recover. Keep the existing PTY lost-ACK recovery only for deliveries that can safely be replayed.

🔴 Broker restart disconnects attached Codex sessions
After a broker restart, native_codex_targets is empty even if the attached Codex session remains open. Receipt restoration preserves old sends, but new messages find no target and the session cannot receive them until it reattaches.
Learn more
An attach stores its target in the new process-local registry field and advertises it in the node inventory. Broker startup restores the pending delivery seam in rehydrate_delivery_seam, but never reconstructs this registry field. A still-running external Codex session does not receive a new MCP registration just because the broker restarted. queue_inbound_for_delivery_mode therefore classifies it as missing; previously queued messages also cannot settle against their recorded route without a matching backend.
Example: Alice attaches thread T as codex-a, then restarts the broker while Codex stays open. A DM sent to codex-a after the restart has no native delivery target despite the original thread still existing.
Recommended fix: Persist sufficient validated target metadata and restore/revalidate it during startup, or establish a reliable reattach handshake before publishing inventory and accepting delivery. Restore the session target as well as its pending receipts.

🔴 Crash window duplicates queued Codex messages
If the broker exits after codex queue commits but before flush_persisted_stores, the saved pending entry lacks sent_route. Restart rehydrates no receipt and can queue the same message again.
Learn more
The route is stamped only after DeliverySeam::send returns, while the event loop writes dirty pending state after the entire handler in flush_persisted_stores. The native transport persists its write independently of this broker. A crash between those events leaves a snapshot without the route, or even without the newly inserted pending delivery. Rehydration then sees no proof of the accepted write, allowing a replay with a new seam to write it again.
Example: The broker's last disk snapshot records del_1 without a route. codex queue writes del_1, then the broker is killed before the handler returns. On restart, del_1 reloads as unsent and is queued twice.
Recommended fix: Persist a provisional in-doubt native route record before starting the external queue command and make the delivery insertion durable before acknowledging custody. Reconcile provisional records with Codex's queue and rollout on restart without re-sending on uncertainty.

🟥 Agent messages can reach another Codex thread
With a valid agent token, AttachNativeCodex accepts any indexed thread whose cwd matches the supplied cwd. It never verifies that the thread belongs to that agent, so messages can reach a different Codex session.

For every native delivery, queue_message places the full message in codex command-line arguments. Local process inspection can expose that message while the command runs.

Native send aborted by short timeout
High Severity
Inbound and fleet native sends run insert_and_attempt_delivery under timeout(retry_interval), defaulting to one second. That window must cover both the codex queue --help capability probe and the actual codex queue write, which itself allows 15 seconds. When the outer timer fires, the seam already holds an in-doubt receipt, so the delivery is capped as terminal and cannot fall back or retry, even if Codex never started writing.

Queued Codex mail marked in doubt
High Severity
Native settlement treats SettleStatus::HandedOver the same as an unknown outcome and dead-letters the delivery after NATIVE_DELIVERY_SETTLEMENT_TIMEOUT (two minutes). A marker that is still in Codex queued_items is a successful durable handoff waiting for an idle or busy session to consume it, not a failed observation. Timing that out drops the withheld fleet ack and lets the engine re-surface the same msg_id.

Recipient-gone ignores native handoff
Medium Severity
When has_delivery_target is false, retry_pending_delivery always returns Failed with recipient gone. That path never consults handed_over_route_label, so a delivery already accepted by codex queue is dead-lettered as auto-redeliverable. Teardown was updated to mark that case in doubt; this maintenance path was not.

Inline comments:
In `@CHANGELOG.md`:
- Around line 68-78: Move the new `Changed` and `Fixed` entries from the
published `[12.4.0]` section to the existing `[Unreleased - Major]` section in
the changelog. Keep both classifications and preserve the pending heading as
`Major`.
In `@crates/broker/src/codex_thread.rs`:
- Around line 41-43: Update `marker_for` to produce a complete, delimited
delivery-marker token, and update `body_with_marker` to append that token
without wrapping it again. Ensure delivery checks match the complete token so
IDs that share a prefix are not confused, and update fixtures that construct
markers manually.
In `@crates/broker/src/delivery/backend.rs`:
- Around line 591-601: Bound the growth of `DeliverySeam::evicted` by removing
tombstones when deliveries reach terminal settlement or by maintaining them in a
separately capped FIFO. If using a cap, document that IDs beyond it fall back to
the persisted `sent_route` check.
In `@crates/broker/src/delivery/codex_queue.rs`:
- Line 500: Gate the PermissionsExt import in the tests module with the Unix
platform condition, matching the existing Unix-only helpers so platform-neutral
tests can compile on non-Unix targets.
In `@crates/broker/src/runtime/api.rs`:
- Around line 1864-1901: Update the self-registration flow around
resolve_fleet_agent_token_identity, bind_http_registered_agent_to_node, and
workers.attach_native_codex so an attach failure leaves neither the fleet
identity binding nor the remote node binding in place; perform attach before
binding if the flow permits, otherwise roll back both bindings before replying
with the error.
- Around line 1910-1921: Use one shared active-agent helper that includes both
workers and native_codex_targets, and use it when building fleet load snapshots
in this publish_fleet_load_snapshot call and the worker-only release paths.
Ensure every snapshot derives active_agents from the same formula so attached
native targets are not omitted.
In `@crates/broker/src/runtime/delivery.rs`:
- Around line 490-494: Update the `sent_route` restoration in
`rehydrate_delivery_seam` to discard persisted routes that do not survive a
broker restart, using `PersistedDeliveryRoute::survives_broker_restart`.
Preserve surviving routes so they continue to seed the delivery seam after
reload.
In `@crates/broker/src/runtime/maintenance.rs`:
- Around line 203-220: In the native settlement terminal branches in the
maintenance sweep, apply the PTY unobserved path’s cursor-abandonment and
prefix-disposal flow before removing or discarding a PendingDelivery, and insert
its delivery ID into terminal_failed_deliveries so late acknowledgments cannot
resurrect it. Preserve the existing terminal outcome handling.
In `@crates/broker/src/runtime/worker_events.rs`:
- Around line 871-872: In the delivery verification handler, gate the
`delivery_unobserved` emission on whether
`clear_pending_delivery_if_event_matches` actually removed a pending entry, not
on the `unobserved` classification from `is_observed`. Track that settlement
result separately and use it for the emission condition so an
already-acknowledged replay does not produce a contradictory event.
In `@crates/broker/src/worker.rs`:
- Around line 1840-1843: Update spawn_with_generation to reject names present in
native_codex_targets as well as workers. In release, only return after detaching
a native Codex target when no broker-owned worker with that name exists, so the
worker release path still runs when both are registered.
In `@docs/native-delivery-migration.md`:
- Line 3: Update the status line in the native delivery migration document to
reflect the current state by phase: phase 0 and phase 1 are shipped, and this PR
adds the seam and the codex queue route. Remove the claim that nothing is built,
and avoid implying that later phases are complete.
In `@flows/migrate/native-delivery.spec.ts`:
- Line 632: Update the forbid marker in the test result configuration so it
matches the exact zero-passed Cargo summary prefix, rather than the ambiguous
substring “0 passed”; keep the check from flagging runs with 10 or more passing
tests.
- Around line 625-636: Update PhaseConfig and the invariant-test command
construction to use the phase’s configured invariant test files, preserving the
existing single-file fallback. Include integration targets for files under tests
and add the library test target when any file is under src; reuse this command
in the invariant-tests, rust-final, and final-evidence recorders so all three
run the same phase-specific tests.
In `@packages/cli/src/cli/agent-relay-mcp.ts`:
- Around line 1180-1193: Add a timeout signal to the
`/api/native-delivery/codex/attach` fetch in the native Codex attach flow, using
`connection.requestTimeoutMs` with a 30-second fallback. Catch timeout abort
errors and report them with the existing “Agent registered, but native Codex
delivery could not attach” prefix.
In `@packages/contracts/fixtures/event-fixtures.json`:
- Around line 124-134: Update the seq values in the event fixture so
delivery_unobserved and each following event have unique, increasing sequence
numbers; preserve the ordering and event data.
In `@scripts/migrate/mutation-proof.mjs`:
- Around line 507-511: Update run() to preserve the spawned command’s exit
status and execution error alongside its output. In the restored-suite checks,
fail before writing mutation-restored-green.txt, mutation-proof.json, or
mutation-proof.md if either suite fails, so proof artifacts are only emitted
after both restored suites succeed.
In `@scripts/migrate/native-delivery-gates.mjs`:
- Around line 2006-2010: Extract the artifact-set digest calculation from seal()
into a reusable helper, then update accept() to report a problem when
seal-final.json is missing and to compare the helper’s digest of the live tree
and evidence with the stored digest before accepting signoffs. Keep the
per-signoff check that binds each signoff to seal-final.json.
In `@tests/benchmarks/stress.ts`:
- Around line 9-11: Update the four HarnessDriverClient.spawn calls in main() to
use brokerTestEnv() instead of process.env, and import brokerTestEnv from
./harness.js so all stress benchmarks use the same injection-rate default.
In `@tests/e2e/unlaunched/session-host.ts`:
- Around line 153-158: Update `parentPidOf` to use a static `execFileSync`
import from `node:child_process` instead of calling `require` at runtime, and
retain the existing process lookup and error handling.

| ### Changed | ||
|
|
||
| - Codex native delivery appends a `relay-delivery-id` marker to queued messages so Relay can confirm delivery from the Codex thread record without fabricating an acknowledgement. | ||
| - A Codex delivery is acknowledged (and its Relaycast read receipt published) only once the marker appears in the thread rollout as a consumed user item. A message still sitting in Codex's own queue is reported as handed over, so an idle or exited session no longer produces a read receipt for a message nobody read. | ||
| - Setting `manual_flush` on an agent reachable only over a native route (an attached Codex thread) is refused with `manual_flush_unsupported` (HTTP 409); inbound messages for such an agent always drain over the native route instead of parking in a queue the flush path cannot empty. | ||
|
|
||
| ### Fixed | ||
|
|
||
| - Broker PTY delivery now fails closed when a handoff deadline races an admitted write, preventing fleet retries from injecting the same message twice and retaining cursor-purged siblings as non-redeliverable dead letters. | ||
| - Releasing an agent, or a worker dying, no longer marks a delivery that already reached a durable native route as freely redeliverable: it is dead-lettered in doubt and the withheld engine acknowledgement is recorded on the node delivery probe rather than dropped. | ||
| - A broker restart no longer re-queues a Codex message that a previous broker lifetime already handed to `codex queue`: the accepted route is persisted with the pending delivery and restored into the delivery seam before the first retry. |

Terminate delivery markers before substring matching.
The fleet wire accepts any String for Deliver.delivery_id, and the production fleet path preserves it. If the fleet sends IDs such as delivery-1 and delivery-10, the current substring checks can report delivery-1 as Consumed or Queued when only delivery-10 was observed. A consumed false positive returns Acked and can publish a read receipt for the wrong delivery. The same prefix match can prevent body_with_marker from adding the correct marker.
Use the complete marker token in every match:
Suggested fix
pub(crate) fn marker_for(delivery_id: &DeliveryId) -> String {
- format!("relay-delivery-id:{}", delivery_id.as_str())
+ format!("<!-- relay-delivery-id:{} -->", delivery_id.as_str())
}

🚀 Performance & Scalability | 🟠 Major | 🏗️ Heavy lift
evicted tombstones grow without bound.
record_receipt adds every evicted delivery id to self.evicted. An entry leaves self.evicted only when the same id is recorded again. Receipts are not removed when a delivery is acknowledged, so every delivery past the first 4096 eventually becomes a permanent tombstone. For a long-running broker with steady traffic, DeliverySeam memory grows linearly with lifetime delivery count.
Bound the tombstone set. Two options:
- Drop the tombstone when the pending delivery reaches a terminal settlement (confirmed or dead-lettered).
- Keep the tombstones in a second, larger FIFO with its own cap.
If you use a cap, note in a comment that ids past the tombstone cap fall back to the persisted sent_route check.

A Unix-only import breaks test builds on non-Unix targets.
use std::os::unix::fs::PermissionsExt; sits at the top of the tests module with no #[cfg(unix)]. The helpers that use it are already #[cfg(unix)], but the module-level import is not. The workspace has Windows dependencies (windows-sys in relay-pty), so cargo test on Windows fails to compile this module. It also removes the platform-neutral tests, such as an_unselectable_codex_backend_refuses_before_any_write.

Undo the identity and node binding when attach_native_codex fails.
resolve_fleet_agent_token_identity binds the identity in fleet_delivery_book. bind_http_registered_agent_to_node then binds it to this node remotely. Both steps run before workers.attach_native_codex. If attach fails at Line 1898, the handler replies with an error and keeps both bindings. The engine routes deliveries for name to this node, but no delivery target exists. Those deliveries end as WorkerMissing/"recipient gone".
Check that attach can succeed before binding, or undo the bindings on failure (for example with prune_fleet_agent_state or an ordered deregister).

The restored-green check does not look at exit status, so a red suite is recorded as green.
run() returns only the combined stdout and stderr. The script never checks result.status or result.error. At Lines 567-582 it writes mutation-restored-green.txt whatever the outcome. It then emits mutation-proof.json and a mutation-proof.md that states: "the suites are green on the restored tree".
This can happen in two ways. The restore may leave a guarded file wrong, or the restored suite may regress. In both cases the proof still claims green. It also stamps digests that seam-rules accepts. The generated file says it "cannot describe a mutation that was never run", but it can describe a green run that never happened.
Return the status from run(). Fail before you write the JSON and markdown if either restored suite exits non-zero.

seal() already knows how to compute artifactSetSha256 from evidence plus changedFiles(). Extract that into a helper. In accept, add a problem if seal-final.json is missing. Also add a problem if the recomputed digest differs from the stored digest.
🔒 Proposed fix
- const sealFile = path.join(art, 'seal-final.json');
- if (existsSync(sealFile) && signoff.artifactSetSha256 !== readJson(sealFile).artifactSetSha256)
- problems.push(`${provider} signoff cites a different artifact set than seal-final.json`);
+ const sealFile = path.join(art, 'seal-final.json');
+ if (!existsSync(sealFile)) {
+ problems.push(`${provider} signoff cannot be bound: seal-final.json is missing`);
+ } else if (signoff.artifactSetSha256 !== readJson(sealFile).artifactSetSha256) {
+ problems.push(`${provider} signoff cites a different artifact set than seal-final.json`);
+ }Before the signoff loop, add this. computeSealDigest(art, 'final') is the digest logic extracted from seal():
const sealFile = path.join(art, 'seal-final.json');
if (existsSync(sealFile) && computeSealDigest(art, 'final') !== readJson(sealFile).artifactSetSha256) {
problems.push('tree or evidence changed after seal-final; signoffs no longer describe it');

The stress brokers skip the brokerTestEnv() injection-rate default.
startBroker() in tests/benchmarks/harness.ts now spawns with brokerTestEnv(), which defaults RELAY_INJECT_RATE_MS to 0. main() in this file still passes env: process.env to all four HarnessDriverClient.spawn calls.
The cat receivers therefore inject at the paced 5 ms default. The reliability benchmark injects at 0 ms. The two benchmarks measure different pacing. In addition, more echo verifications can time out here. Unobserved counts then rise, and the r.unobserved > r.verified verdict can flip.
Import brokerTestEnv and use it in each spawn call.

Use a static import for execFileSync in parentPidOf.
This module is ESM. It uses static import statements. parentPidOf calls require('node:child_process') at runtime. If the test runner does not inject require into ESM modules, the call throws a ReferenceError. The catch block turns that error into null. The assertions in tests/e2e/unlaunched/unlaunched-delivery.test.ts then fail: "could not read the session host pid lineage". tests/e2e/unlaunched/codex-session-host.ts already imports execFileSync statically.

isObservedVerification disagrees with the broker when verification is missing.
The doc comment says this helper mirrors is_observed. The broker handles a missing field differently. In crates/broker/src/runtime/worker_events.rs (line 862), the broker defaults a missing verification to "missing" and classifies it as unobserved. It emits delivery_unobserved and does not confirm the delivery. isUnobservedDelivery in tests/benchmarks/harness.ts also treats a missing field as unobserved.
This helper treats the same frame as observed. For that shape, assertDeliveryObservationLedger then:
- expects a
delivery_ackthat the broker never sends, and - rejects the
delivery_unobservedevent that the broker does emit.
Align the default with the broker. If older recordings need the lenient behavior, handle them in a separate, explicitly named helper.
Proposed fix
- // A frame with no `verification` predates the field; treat it as observed so
- // this helper cannot retroactively fail older recordings.
- return verification === undefined || OBSERVED_VERIFICATIONS.has(verification);
+ // Match the broker: a frame without `verification` is not evidence of an observation.
+ return verification !== undefined && OBSERVED_VERIFICATIONS.has(verification);Also update the matching case in tests/integration/broker/evals/delivery/observation-ledger.unit.test.ts (lines 45-51).

Overview
Introduces a route-aware delivery seam in the broker so sends go through pluggable backends (PTY first, Codex
codex queuewhen eligible) with shared rules: fallback only before a write commits, one receipt per delivery id, settlement tied to the route that accepted the send, and acknowledgements only when observation evidence exists.Codex existing-session delivery adds authenticated attach via
POST /api/native-delivery/codex/attach, queues messages with arelay-delivery-idmarker, and settles by reading Codex’s rollout (consumed user input) vsqueue_1.sqlite(still queued—not acked). Agents reachable only on a native route rejectmanual_flushwith HTTP 409; pending deliveries persistsent_routeand rehydrate the seam after restart so broker retries do not double-queue to Codex.PTY / fleet reliability fixes tighten echo verification (boundary overlap, CRLF/soft-wrap tolerance), stop emitting
delivery_ackon echo timeout (only explicittimeout_fallback), unify observed verification wire values (echo,process_exit), fix fleet cursor handling when abandoning unobserved deliveries (mark_delivery_seen, reported ack floors), and retain in-doubt dead letters without auto-redelivery.
