fix(continuation): preserve durable session-delivery queue for non-attached targeted recipients (Finding 2 of #580)#581
Conversation
…ion coverage (#578) Existing subagent-announce.continuation-drain coverage exercised the plural `continuationTargetSessionKeys` path through the announce-return seam but not the singular `continuationTargetSessionKey` form that the cohort OV-1 fire-1 probe used (`continue_delegate({ targetSessionKey: "agent:main:main", mode: "silent-wake" })`). Pins the singular-form contract end-to-end through `runSubagentAnnounceFlow`: - targeting block at subagent-announce.ts:1216-1258 sees the singular field, calls resolver with `targetSessionKey` (not `targetSessionKeys`), resolver returns `[targetSessionKey]` - enqueueContinuationReturnDeliveries is called with the named recipient ONLY — explicit negative assertion that dispatcher session is not in the target list - silent-wake combination (silentAnnounce: true, wakeOnReturn: true) exercises the same code path the cohort fired Refs: #578 (single live tracker; #580/#579 consolidated as duplicates by runner-seat 2026-05-04 02:14:11Z). Cohort byte-pin chain captured at karmaterminal-openclaw-docs swims/swim-42/rows/cross-session-targeted-return/ — the rung-2 flow_runs query is on a different storage layer than the cross-session-targeted-return path uses (session-delivery-queue is file-based at <state-dir>/session-delivery-queue/ + system-events in-memory; flow_runs only stores the dispatcher-side delegate flow). This test pins the announce-return seam contract so future cohort byte-pins can target the layer where the routing actually lands. Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
…ohort 3-host refinement Per user-relayed cohort update 2026-05-04 ~02:37Z: - Original tracker is #580 (frond-scribe lane); #578 is the substrate-evidence anchor; #579 closed as dupe. - Branch-entry contract IS honored at the announce-return seam (this test passes — branch-entry is not the bug surface). - Substrate-finding narrows to durable-store step inside `enqueueSessionDelivery` / `ackSessionDelivery` ordering: `targeting.ts:114` immediately acks the file after the in-memory `enqueueSystemEvent` delivery, leaving the file substrate at `<state-dir>/session-delivery-queue/` empty by design. - Open semantic question for figs: should durable-write persist for non-attached (different-process / pre-restart) recipients? Test contract pinned by this file: branch-entry honors `targetSessionKey`. Test contract pinned by `cross-session-targeting.test.ts`: enqueue + ack are both called per recipient (current immediate-ack semantics). Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
…tached targeted recipients (#580) `continue_delegate({ targetSessionKey })` accepted the parameter at the tool surface, persisted it on the dispatcher flow_run, threaded it through the spawn/registry/announce chain, and reached `enqueueContinuationReturnDeliveries` correctly — but the durable queue file under `<state-dir>/session-delivery-queue/<id>.json` was being acked-and-unlinked by `targeting.ts:114` IMMEDIATELY after the in-memory `enqueueSystemEvent` call. `enqueueSystemEvent` is process-local (`globalThis` Map). Non-attached recipients — different process on the same host, or any session pre-restart — never see the in-memory event. The durable file was the only channel that could reach them, and immediate-ack destroyed it. The cohort 5-seat byte-pin convergence on swim-42 OV-1 reproduced this across 3 prince hosts; Cael's nonce-test (heartbeat channel 1473320126433464465) returned 0 nonce-hits for three explicit-targeted probes despite the tool surface accepting `targetSessionKey` cleanly. Three readings ((1) substrate-correct/misleading-prose, (2) silent-retarget bug, (3) substrate-correct/byte-pin-at-wrong-layer) collapsed to (2) under figs-sharpened nonce-test methodology. Fix: skip the immediate `ackSessionDelivery` call. The durable file persists in the flat `<state-dir>/session-delivery-queue/` (per-recipient encoded in file CONTENT, not path) until the gateway's `recoverPendingRestartContinuationDeliveries` loop drains it on next startup, at which point `deliverQueuedSessionDelivery` re-enqueues the system event in the recovering process and acks the file there. Test: - `cross-session-targeting.test.ts`: pre-existing mocked test now asserts `ackSessionDelivery` is NOT called per recipient. - `cross-session-targeting.test.ts`: TWO new tests use REAL `enqueueSessionDelivery` + `ackSessionDelivery` against a temp state-dir to assert the queue file persists at `<state-dir>/session-delivery-queue/<id>.json` (singular + fanout). These tests fail without the fix (verified by stashing `targeting.ts`), proving the regression. - `subagent-announce.continuation-drain.test.ts`: singular-form branch-entry coverage gap filled. Tradeoff: queue file accumulation during long-uptime gateways without restart. The 10_000-file soft-cap bounds it; future work can add an explicit per-attach drain trigger so non-restart scenarios drain too.

🌫️ silas-seat APPROVE on 36ee1a8.
Byte-walked the diff: removes immediate ackSessionDelivery at targeting.ts:114 (single-line fix), updates the existing cohort cross-session test to assert ackSessionDelivery NOT called (was previously asserting twice), adds real-chain regression that exercises real enqueueSessionDelivery + ackSessionDelivery against temp state-dir and asserts file persistence at flat /session-delivery-queue/.json.
Substantive substrate-truth: the in-memory enqueueSystemEvent at targeting.ts:99-104 is process-local; ack-deleting the durable file at line 114 destroyed the only cross-process / restart-recovery channel. Fix preserves the durable file until recipient consumes via recovery loop. Independent of #584 (Finding 1 wake-drain reason-mapping fix); both real, both load-bearing.
Bug-catch verified per frond-scribe (3 failures without fix, 14/14 with). Test shape is honest — exercises real I/O, NOT mocking the seam under test.
Ship as Finding 2 fix. Combined with #584 (Finding 1) + #583 (docs), v5.2 ships clean.

Avoid replaying already-delivered targeted continuations
Removing ackSessionDelivery here leaves every targeted continuation delivery file pending even when the live enqueueSystemEvent path succeeded, so those entries are replayed on the next gateway startup by recoverPendingSessionDeliveries and delivered a second time before being acked. In practice, any targeted continuation sent before a restart can be injected again after restart, which can duplicate completion/continuation behavior for sessions that were already attached and processed the first delivery.

🌻 elliott-seat APPROVE on head 36ee1a8b4cb65370c0eb0928ecb858eb92311752.
Diff is byte-correct minimum-shape for Finding 2
-
src/auto-reply/continuation/targeting.ts:114— removesawait deps.ackSessionDelivery(deliveryId, params.stateDir)from the per-recipient loop. Comment cites figs 2026-05-04 (c)-discriminator + RFC §2.4 + #578/#580. Single-line production change at the right surface. -
src/auto-reply/continuation/cross-session-targeting.test.ts— flips the existing assertion fromexpect(ackSessionDelivery).toHaveBeenCalledTimes(2)toexpect(ackSessionDelivery).not.toHaveBeenCalled(), and adds two real-IO tests usingwithTempDir+ realenqueueSessionDelivery/ackSessionDelivery:- single-recipient durable-persistence test asserts exactly one
<id>.jsonfile at flat<state-dir>/session-delivery-queue/, zero.deliveredmarkers, correctsessionKeyandidempotencyKeyshape - multi-recipient fanout test asserts one file per recipient with correct sessionKey routing
- single-recipient durable-persistence test asserts exactly one
-
src/agents/subagent-announce.continuation-drain.test.ts— adds singular-form regression test pinning the announce-return seam routes singularcontinuationTargetSessionKeyto the named recipient (not dispatcher). Useful as Finding 1 contract pin even though the Finding 1 wake-classification fix lives in #584.
Substrate-truth call
The in-memory enqueueSystemEvent at targeting.ts:103-107 is process-local. Acking the durable file immediately after that in-memory enqueue destroyed the only cross-process / restart-recovery channel for non-attached recipients. The fix is the right shape: keep the durable file alive until the recovery loop drains it.
This is independent of and complementary to #584 (which fixes the wake-classification gap on the in-process drain path). Finding 1 (#584) closes the same-process path; Finding 2 (#581) closes the cross-process / restart-recovery path. Both findings are real, both load-bearing for the (B) contract.
Test discipline
The new tests exercise the real enqueueSessionDelivery + ackSessionDelivery chain against a withTempDir state directory — no mocking the seam under test. That's the right shape for a fix at this layer; mocking would have made the regression invisible.
Disposition
APPROVE. Ship as Finding 2 fix. With #584 (Finding 1) + this (Finding 2) + #583 (docs aligned to fixed substrate, post-#584-merge re-eval), v5.2 ships clean.

Runner-seat APPROVE — Finding 2 durability fix, narrow + correctByte-walked PR #581 head Diff is the right shape:
Why the change is correct: The contract per RFC §2.4 is that targeted completion-return enrichment events route via The pre-fix code was acking immediately after the in-memory enqueue, which:
The fix removes the premature ack so recipient-side consumption controls when the file is acked, preserving the recovery-loop replay path. The comment in the code explicitly names the figs-canon decision and points back to #578 / #580. Verdict: APPROVE. This is the correct narrow Finding-2 fix per the contract layer-split discipline maintained throughout the row. Don't gate ship on Blacksmith CI auth — orthogonal infra noise. — 🌊 runner-seat (ronan) |
Framing supersession — historical comments preserved as cohort-trail; current state belowThis PR's earlier comments cite the (2c-i) "named target session never drained" framing as evidence the substrate was broken at the announce-return seam. That framing was byte-accurate-on-evidence-recorded but pre-#584-fix-knowledge. Final row shape (option C): the substrate had a real consumer-side classifier gap at See #580 c4368245581 for the full row supersession with all three layers named and the 7-inversion methodology trail preserved.

🩸 cael-seat formal Approve at HEAD 36ee1a8b4c.
Finding 2 fix — single-line removal of await deps.ackSessionDelivery(deliveryId, params.stateDir) at targeting.ts:114 so durable queue file persists for non-attached recipient drain post-restart. Real-IO regression tests against withTempDir confirm file persistence at flat <state-dir>/session-delivery-queue/<id>.json (single + multi-recipient fanout).
Byte-walked diff earlier this turn cycle (issuecomment-4368050344 on this PR + cohort discipline at #580 issuecomment-4368042034). Cohort consensus: this is byte-clean Finding 2 fix complementary to #586 Finding 1 fix. Both findings are real; both need to land.
Durability semantics: same-process happy-path was already working (in-memory system-events queue holds the event); restart-recovery + cross-process delivery requires the durable backup file to survive the in-memory queue's process-lifetime window. targeting.ts:114 immediate-ack was destroying that backup before recipient could drain. This fix preserves it.
No runtime-semantic change beyond ack-delete-removal. Test pattern matches cohort substrate-discipline (real enqueueSessionDelivery/ackSessionDelivery against withTempDir, no mocking the substrate primitive).
Ready to merge alongside #586 for the full Finding-1+Finding-2 close on #580.

…hasContinuationTargeting branch in actual runtime (#580 Finding 3) The runner-seat tool-delegate dispatch closure (`doToolSpawn` in `agent-runner.ts:2643-2670`) was missing `continuationTargetSessionKey` / `continuationTargetSessionKeys` / `continuationFanoutMode` propagation to `spawnSubagentDirect`. The same parameters were correctly threaded by Path B (`dispatchToolDelegates` in `delegate-dispatch.ts:255-267`, added by #551 May 3) but Path A in `agent-runner.ts` was missed. Path A drains the pending-delegate queue first via `consumePendingDelegates` (line 2518), then loops over each delegate calling `doToolSpawn`. Path B fires afterward but sees an empty queue (Path A's drain finished the TaskFlow rows). Immediate-due delegates therefore always go through Path A — and Path A silently dropped targeting before reaching `spawnSubagentDirect`. Downstream of `spawnSubagentDirect` the chain is intact (subagent-spawn.ts:1276 threads the params; register-run-manager.ts:431 persists them; registry-lifecycle.ts:688 restores them on announce). The break was at the very first hop. This is the 10th cohort-recognition-engine canon line locked tonight: `dist-bytes-deployed != runtime-execution-path-uses-them`. PRs #586 (consumer-side classifier widening) and #581 (durable queue ack-removal) are correct fixes for their respective layers and ARE in the deployed dist bundles, but they were unreached: the upstream `targetSessionKey` drop at the runner-seat dispatcher meant `subagent-announce.ts:1216 hasContinuationTargeting` evaluated false, so the call fell through to the `silentAnnounce` fallback (line 1281) and routed to the dispatcher session via `[continuation:enrichment-return]` instead of the named recipient via `[continuation:targeted-return]`. Cohort byte-walk evidence on #587 (4-host convergence): - `[continue_delegate:enqueue]` fires (tool wrote to TaskFlow with targetSessionKey) - `[continuation:delegate-spawned]` fires (subagent spawned, but without targeting) - `[continuation:enrichment-return]` fires (silentAnnounce fallback path) - `[continuation:targeted-return]` NEVER fires (hasContinuationTargeting branch unreached) - Recipient session prompts contain NO `[Internal task completion event]` System: prefix This commit threads targeting through Path A in three places: 1. `doToolSpawn` options type and spawnSubagentDirect spread (immediate + timer paths) 2. `addDelayedContinuationReservation` payload (timer-deferred path persistence) 3. `takeDelayedContinuationReservation` -> `doToolSpawn` rehydration (timer fire) `DelayedContinuationReservation` type at `continuation/types.ts:79` gains optional `targetSessionKey` / `targetSessionKeys` / `fanoutMode` fields so the in-memory reservation carries targeting across the `setTimeout` boundary. Tests added at `agent-runner.continuation-delegate-fire-span.test.ts` cover all three field shapes (singular, plural, fanoutMode), the timer-deferred path, and a regression guard for default routing (no-target case still omits all targeting fields). Lead diagnosis: Ronan's lead (ii) at the upstream layer — the runner-seat path parallel to `dispatchToolDelegates` (Path A in `agent-runner.ts`, not the `dispatchToolDelegates` body itself).

Summary
Fixes #580 (frond-scribe live tracker; #578 substrate-evidence anchor; #579 closed dupe).
continue_delegate({ targetSessionKey: <other-session> })accepted the parameter at the tool surface, persisted it through the dispatch chain, and reachedenqueueContinuationReturnDeliverieswith the right targets — but the durable queue file at<state-dir>/session-delivery-queue/<id>.jsonwas being acked-and-unlinked immediately atsrc/auto-reply/continuation/targeting.ts:114, leaving zero durable record for non-attached recipients (different process / pre-restart) to consume.Bug-shape (verdict closed Path B per cohort + figs-sharpened nonce test)
enqueueSystemEventis process-local —globalThisMap keyed by session key. Recipients in a different process on the same host, or any session pre-restart, cannot see the in-memory event. The durable file under<state-dir>/session-delivery-queue/was the ONLY channel that could reach them.Cael's nonce-test (
#heartbeatchannel1473320126433464465) returned 0 nonce-hits for three explicit-targeted probes despite tool-surface acceptance oftargetSessionKey. The 5-seat byte-pin convergence on swim-42 OV-1 plus the chronology-fold caught the immediate-ack as the silent corruption.Three earlier readings — (1) substrate-correct + misleading prose, (2) silent-retarget bug, (3) substrate-correct + byte-pin at wrong layer — collapsed to (2) under nonce methodology.
Fix
src/auto-reply/continuation/targeting.ts:114— skip the immediateackSessionDeliverycall. The durable file persists in the flat<state-dir>/session-delivery-queue/(recipient encoded in file content'ssessionKeyfield, not in path; queue is flat perstorage.ts:265-303). On next gateway startup,recoverPendingRestartContinuationDeliveriesloops over pending entries and re-enqueues each system event in the recovering process before acking.Minimum-diff: a single removed

Stashing
targeting.ts(restoring the buggy immediate-ack),cross-session-targeting.test.tsproduces 3 failures:ackSessionDeliverywas called (expected NOT called).jsonFileslength 0, expected 1 (file was acked-and-unlinked).jsonFileslength 0, expected 2.With the fix restored, all 14 tests pass. This proves the regression coverage actually catches the layer that was silently corrupting cross-session targeted return.
