The event gate's sleep now wakes the agent at its end, through a stop and a restart, by the gate's own clock, and only while the agent that set it exists. dispose() clears the sleep's timer and keeps the sleep, and until the next start() nothing arms a sleep's or a self-wake's timer. The next start() on the same framework arms the wake again for the sleep's end, or wakes the agent at once if the sleep ended while it was stopped. A timer that fires before the sleep's end waits out the rest rather than dropping the wake, and the sleep and self-wake of a conversation fork or an ephemeral run end with it.

Part of #646: this ends a fork's sleep with the fork. Whether a fork's sleep should hold back the whole gate is the rest of that issue.

Problem

setSleep() arms a timer that wakes the agent at the sleep's end. Three things kept that wake from coming when it should.

stop(). dispose(), which the framework's stop() calls, cleared the gate's debounce and self-wake timers, and left the sleep's. So after stop():

• the timer held the process until the sleep's end, an hour for sleep(3600);
• at the sleep's end, the stopped framework traced sleep:expired, cleared the sleep and queued a wake in its pending requests, which stop() leaves as they are;
• with a store the caller owns, the next start() drove that queued wake, so the agent woke once at the start. With a store the framework opened from storePath, start() after stop() is refused, so nothing drove it.

connectome-host's session switch stops one framework and makes another, so a session switched while its agent slept left the old framework's timer running until the sleep's end. A turn still running after dispose(), as one can be after a stop() whose stream cancel throws, could also arm a new sleep or self-wake timer on the stopped framework; connectome-host goes on with its switch after a stop() that rejects.

A timer that fires early. The timer's handler dropped the wake whenever the gate's clock hadn't reached the sleep's end, and nothing armed it again, so the agent slept on until something else woke it. On Node a timer can fire a millisecond early, a clock set back makes it early by the step, and setTimeout holds at most 2^31−1 ms, about 24.8 days, and fires a longer delay after 1 ms.

A gone agent's sleep and self-wake. The gate's sleep holds back every agent's wakes but the heartbeat's and a privileged user's, and its wake goes to the agent that set it. A conversation fork's sleep outlived the fork, at its idle close or at stop(), which ends every live fork, and an ephemeral run's outlived the run. So the other agents' wakes were held back until its end, and its wake then went to a name that no longer existed. A pending skip_reply self-wake of either fired into the gone name the same way.

What ran on main (Linux, Node 24.22.0):

• at 7e09923d, a gate put to sleep for 1 s and disposed at once traced sleep:expired and requested a wake 1 s later; a 1-hour sleep's timer stayed active after dispose(), until clearSleep(); and a framework with the gate on, put to sleep for 600 ms and stopped, traced the expiry and queued the wake while stopped, and with a caller-owned store the next start() drove one turn;
• of 1,000 timers of 1 to 40 ms armed the way setSleep() arms them, 7, 8 and 10 in three runs fired a millisecond before their deadline by Date.now(); with Bun 1.4.3, none of 2,000 did;
• at 97ca7eba, this change's tests for the early timer, the long sleep, and a fork's and an ephemeral run's sleep fail (Tests, below).

Changes

• dispose() clears the sleep's timer and keeps the sleep: its end, note and agent. It also marks the gate disposed, and until the next resumeSleep() neither armSleepWake() nor armSelfWake() arms a timer.
• EventGate.resumeSleep(), new, which the framework's start() calls before its loop's first pass. It clears the mark. For a sleep still ahead, it arms the wake for what remains; for one that ended while stopped, it wakes the agent at once; with no sleep, it does nothing.
• armSleepWake(), the one place the sleep's timer is armed, arms it for the sleep's end by the gate's own now(), for at most MAX_TIMER_MS, the longest delay one timer holds. That constant is src/deadline-timer.ts's, now exported.
• wakeFromSleep(), the timer's handler, arms the rest when it fires before the sleep's end by the gate's clock, where it returned before. It cancels a sleep timer still armed rather than dropping its handle, as one can be when resumeSleep() finds the sleep already over.
• EventGate.agentGone(agentName), new, cancels that agent's pending self-wake and ends the sleep if that agent set it. A fork's end (disposeConversationAgent(), at its idle close and at stop()) and an ephemeral run's end call it, beside each one's codeExecution.scripts.agentGone().
• armSelfWake() returns whether it armed, and the skip_reply log line says when the framework has stopped and nothing was armed.

What each part is for

• The line in dispose() is the fix for the stop: once stop() has disposed the gate, the sleep's timer neither fires into the stopped framework nor holds the process.
• The disposed mark keeps that true for a turn still running after dispose(), for a sleep and for a self-wake. A sleep set then is kept, and start() arms it.
• resumeSleep()'s re-arm keeps a restarted framework's sleep whole. The sleep's suppression goes on after start(), since the gate keeps sleepUntil, so its wake has to go on too.
• resumeSleep()'s wake at once keeps what main does for a sleep that ended while stopped, where the queued wake drove a turn at the next start.
• The call in start() is where a lifecycle begins. It comes before the loop's first pass, which takes every pending request at once, so a wake owed at start joins a request already pending, such as an operator's nudge, in one turn, as main's queued wake did.
• The re-arm in wakeFromSleep() brings the wake at the sleep's end whatever the timer does: a step of a long sleep, a timer that fires early, a clock set back. It reads the gate's clock once per decision, so no second reading between a check and the wake can drop it.
• The cap keeps a sleep longer than one timer holds waiting in steps, rather than firing at once and arming again every millisecond.
• The gate's own now() keeps the sleep's end and its timer on one clock, the one setSleep() computes the end with, including a clock a caller injects.
• agentGone() ends what a gone agent left armed. Nobody is asleep once the sleeping agent is gone, so the other agents' wakes stop being held back, and neither its sleep's wake nor its self-wake goes to a name that's gone. It only ends that agent's: a sleep the primary set, or one set with no agent, stays.
• The cancel in wakeFromSleep() keeps one sleep timer at a time on every path, so dispose() always reaches it.

Tests

test/event-gate-sleep.test.ts is new, with 13 tests, and test/conversation-routing.test.ts has two more, for a fork's end. These ran on Linux with Node 24.22.0, on main 97ca7eba:

• The test files this change touches: at f5064bc7, which differs from this head only in the changelog fragment, test/event-gate-sleep.test.ts, test/event-gate.test.ts, test/event-gate-selfwake.test.ts and test/conversation-routing.test.ts pass, 106 of 106, three times.

• Red-first: with main's event-gate.ts and framework.ts, plus a no-op resumeSleep() and agentGone() and an armed: true in armSelfWake()'s result (main arms every self-wake), so that the tests compile and fail on behaviour, 12 of the 15 new tests fail. Three pass on main and are controls:

  • "resumeSleep() wakes once at the end of a sleep still ahead" pins the re-arm, since on main the timer dispose() leaves armed does the waking;
  • "a sleep that ended while stopped wakes the agent in one turn with a request already pending at start" pins the call's place before the loop;
  • "agentGone() leaves a sleep another agent set, or one set with no agent" pins what agentGone() leaves alone.

• Each part has a test that fails without it. Each removal below ran on its own, with the four files:

  Removed or changed	Fails

• The whole suite ran at 50987f09, which differs from this head only in test files and the changelog fragment: npm run build is clean from an emptied dist, and npm test passes 5,936 of 5,980, with 44 skipped and none failing. main's CI at 97ca7eba (Ubuntu, Node 24) ran 5,966 and skipped 45. The 14 more here are this change's tests at that commit; this head has 15, since f5064bc7 splits one in two. The one fewer skipped is "under Bun, a failed dial's error leaves no credential in its message, cause or stack", which runs where Bun is installed.

Who notices

• Any agent that sleeps: its wake comes at the sleep's end by the gate's clock. On Node, a sleep whose timer fired a millisecond early now wakes the agent, where it slept on until something else woke it. After a clock set back, the wake comes when the clock reaches the sleep's end, later by the step. A sleep longer than about 24.8 days now wakes the agent at its end.
• An embedder that stops a framework while its agent sleeps: once stop() has disposed the gate, the process no longer waits for the sleep's end, and the stopped framework records no expiry and queues no wake, even if a turn still running then calls sleep or skip_reply with wake_in_seconds. A sleep set then is kept for the next start(). A self-wake asked for then isn't, as a pending one doesn't outlive a stop either (A wake_in_seconds self-wake and a sleep don't survive a restart #627), and the log says it wasn't armed. A sleep that ends during stop()'s own teardown, before it disposes the gate, still records its expiry and queues its wake, which a next start(), where the store allows one, drives once, as before. After the sleep's end, a stopped framework's inferenceDiagnostics().sleepUntil keeps that end, where it read 0 once the timer had fired. getSleepState() reads awake either way.
• An embedder that runs conversation forks or ephemeral runs: a sleep one set ends when it ends, at a fork's idle close, at stop(), or at a run's end, so the primary's wakes go through again, and neither the sleep's wake nor a pending self-wake goes to the gone name.
• connectome-host, whose session switch stops one framework and makes another: after a switch while the agent slept, the old framework's timer no longer runs on to the sleep's end, and the old framework records no expiry and queues no wake.
• An embedder that starts the same framework again (a store it owns): the agent wakes at the sleep's end, or at once if the sleep ended while stopped, as before. The sleep:expired trace for a sleep that ended while stopped now comes at the start rather than at the sleep's end.

Not verified

• connectome-host's session switch: what this says of it rests on reading its switchSession, which stops the framework and makes another, and src/session-switch-stop.ts, which goes on after a stop() that rejects (main 3027eafd). No host ran a switch with this change.
• A sleep that ends during stop()'s own teardown, before it disposes the gate: that sentence rests on reading where stop() calls dispose(). No test reaches that window.
• getSleepState(): "reads awake either way" rests on reading it. No test asserts it.
• A sleep longer than about 24.8 days waking at its end: the test shows that one capped timer stays armed rather than firing at once. That its step wakes or arms the rest at its end rests on the re-arm, which the clock test runs.

Out of scope

• Whether a framework should start again after stop() at all is start() after a completed stop() reuses an instance whose queue, coalescer and watchdog stay stopped #315. This change makes a sleep work on that path, which the code allows today for a store the caller owns. That path only partly works still: stop() closes the framework's one process queue and start() doesn't open it again, so a restarted lifecycle's tool results are dropped.
• A pending wake_in_seconds self-wake, and a sleep, across a restart are A wake_in_seconds self-wake and a sleep don't survive a restart #627: dispose() clears pending self-wakes and nothing arms them again, and a framework made anew on the same store keeps neither.
• Other open pull requests meet this one where both edit the same lines:
  • fix(tool-results): show each block of a content array, never the array's JSON #527 adds lines at the same place in start(). Keeping both sides resolves it.
  • fix(gate): name every problem a wake rule has, and read gate.json's as it ran #452 adds an import beside this change's in event-gate.ts. Keeping both resolves it.
  • fix(gate): persist sleep and self-wake intent across restarts; re-arm on backward clock step #194 changes, for its stored wakes, how setSleep() arms the sleep's timer, what dispose() clears, armSelfWake()'s result, wakeFromSleep()'s re-arm, and where framework.ts arms a skip_reply self-wake. Its re-arm of a timer that fires early is this change's too.

Verdict

Approve. Four minor findings. R1-1 is worth taking in this PR.

The fix is correct and narrow, and the description's claims hold up. We reproduced its red-first result and one of its mutation claims. The change also merges cleanly onto current main, which is 72 commits ahead and includes #616's changes to stop(), and its tests pass there. What's left is mostly around this change, not in it. The new armSleepWake() is now the single place the sleep's timer is armed, and it could use the repo's existing deadline helper to close both timer issues the description leaves to #194. A sleep set by a conversation fork doesn't fit the new contract on the main it will merge into.

This is our first review of this PR; there are no earlier findings to dispose of.

Blockers

None.

Major

None.

Minor

R1-1. armSleepWake() arms a bare setTimeout, and the repo already has the helper that would close both sleep-timer gaps in it.
src/gate/event-gate.ts:1765-1768; the handler's drop is at :1843-1845.

When the timer fires while Date.now() is still short of sleepUntil, wakeFromSleep returns, and nothing arms the timer again. The description lists this as out of scope, along with sleeps longer than about 24.8 days firing at once, and leaves both to #194. Two things change that here:

• This PR makes armSleepWake() the one path both setSleep() and resumeSleep() arm through, so a fix in it covers both.
• test/event-gate-sleep.test.ts:66-79 ("resumeSleep() wakes once at the end of a sleep still ahead") is the suite's first test that waits for a real sleep timer to fire. The other sleep tests use a 3600 s sleep and never wait for it. So the test inherits the drop.

We measured this on Linux with Node 22.21, against the built head. We replayed that test's exact sequence (setSleep(0.4), dispose(), resumeSleep(), wait 600 ms, expect one wake), each run in a fresh tick:

• with nothing else in the tick, no wake was lost in 400 runs;
• with 5 ms of synchronous work earlier in the same tick, 5 of 400 runs lost the wake.

Every lost wake was a timer that fired exactly 1 ms early. A sleep tool call runs mid-turn, after synchronous work, so production looks like the second case. Roughly 1 in 100 sleeps gets no wake of its own, which matches the description's own probe (7 to 10 per 1,000). The agent then stays quiet past its sleep until something else wakes it.

Fix: armAt in src/deadline-timer.ts:17-27, already used by tune-out, does exactly this. At the end of each step it re-reads the wall clock and arms again for whatever is left. It also caps each step at 2^31−1 ms.

private armSleepWake(): void {
  if (this.sleepTimer) clearTimeout(this.sleepTimer);
  armAt(this.sleepUntil, (t) => { this.sleepTimer = t; }, () => this.wakeFromSleep('sleep-expired'));
}

clearSleep() and dispose() still clear the latest step through sleepTimer. One caveat: armAt reads Date.now(), while the gate reads its injectable now (:665). They are the same in production, and no sleep test injects now. If you'd rather keep this.now(), do the same re-check in the helper's callback, with the same cap. With either, the new test is deterministic, and #194, which conflicts with main at the moment, can build on this rather than the reverse.

R1-2. On current main, a conversation fork's sleep is resumed for an agent that stop() has already ended.

This PR's base predates #616, which makes stop() end every live conversation fork. Here is the path on main:

1. A fork takes the template's tool surface ({ ...templateConfig, name }, main src/framework.ts:12484), so it can call sleep.
2. setSleep() records the fork as sleepAgent (event-gate.ts:1734). The sleep is the gate's single, global one: it suppresses non-privileged wakes for every agent (:1055).
3. stop() ends the fork (main framework.ts:3978-3982, then agents.delete at :12647), and only then disposes the gate (:4019).
4. The next start() calls resumeSleep(). The whole gate stays quiet for the rest of a sleep whose agent no longer exists. At its end the wake goes to a name that isn't registered, and processInferenceRequests drops it as agent_not_found (main :13907). Nothing wakes the primary.

This is not a regression: without this PR, the still-armed timer does the same thing on main. But the description states the contract that a sleep kept through a stop() wakes the restarted lifecycle at its end, and on the main this merges into, that is false for a fork's sleep. The idle sweep (main :12760) leaves the same orphaned sleep without any stop.

Fix: clear the gate's sleep when the fork that set it is disposed. For example, add a clearSleepFor(agentName) and call it from disposeConversationAgent; that covers both stop() and the idle sweep. If that is more than this PR should take on, add it to the out-of-scope list so it gets an issue.

R1-3. dispose() clears the sleep's timer but doesn't stop a new one being armed.

dispose() sets no state (event-gate.ts:2013-2043), and setSleep() always arms (:1740). So a turn still running after dispose() can call sleep, which arms a fresh timer on the stopped framework. That brings back, by another path, what this PR fixes. The description names this case under Out of scope.

The window is narrow. With no budget, which is the default (DEFAULT_SHUTDOWN_TIMEOUT_MS = undefined, src/shutdown.ts:2), stop() waits for every stream. A turn can only outlive the teardown in two ways: a caller-given budget runs out, or a stream's cancel() throws (framework.ts:3518-3522). connectome-host calls stop() with no budget and carries on with a session switch after a failed stop (its src/session-switch-stop.ts), so the thrown cancel is the case it can meet.

Fix: this is cheap, and it makes the description's "Who notices" entry for connectome-host hold without that exception.

• Add private disposed = false, set it in dispose(), and clear it at the top of resumeSleep().
• While it is set, armSleepWake() arms nothing. setSleep() still records sleepUntil, so a later resumeSleep() picks the sleep up.
• The same guard fits armSelfWake() (:1781), which a late skip_reply reaches the same way.
• Test: dispose(), setSleep(), assert no new Timeout resource; then resumeSleep(), assert one.

R1-4. The two framework tests assume stop() reaches dispose() within the 1 s sleep.
test/event-gate-sleep.test.ts:116-120 and 148-152.

If teardown takes longer, the sleep expires during it, which the description says is by design, and "nothing expires while stopped" fails without saying why. That during-teardown case itself has no test; the description lists it under Not verified. The risk is low for today's module-less framework. A cheap guard: time await framework.stop(), and if it took as long as the sleep, fail with a message that says so (or skip). Then a slow host's failure won't read as a regression.

Not counted against this PR

The restart path itself belongs to #315. stop() closes the framework's only process queue (framework.ts:3708; it is built once, at :2843), and start() doesn't reopen it. So in the turn a resumed wake drives, any tool result is dropped (pushEvent, :4987-4996). The wake queued before this PR led to the same turn, so this PR changes nothing there. The new framework tests use text-only responses and don't reach it. Keep it in mind when reading the changelog fragment's "The next start() on the same framework…": that path still only partly works.

Verified fine

• Red-first reproduces. With main's event-gate.ts and framework.ts, plus a no-op resumeSleep(), 3 of the 5 new tests fail and 2 pass. These are exactly the three and the two the description names.
• Mutation claim reproduces. Moving the resumeSleep() call after runLoop() fails only the "one turn" test.
• At head, the three gate test files pass 65 of 65, in three runs on Node 22.21. The description used Node 24.22.
• Merged onto current main (clean merge): the gate test files and shutdown-errors.test.ts pass 94 of 94. The call in start() lands in the same place, before runLoop(), and stop() is still dispose()'s only caller.
• resumeSleep() with no sleep does nothing. wakeFromSleep returns before any trace or request when sleepUntil === 0 (event-gate.ts:1845). clearSleep() and expiry both zero it.
• No double wake. An expiry during teardown, before dispose(), zeroes sleepUntil, so the next resumeSleep() does nothing.
• The new trace can't break start(). resumeSleep() can emit sleep:expired synchronously inside start(), and emitTrace (framework.ts:22100) catches a listener's throw.
• The one-turn claim holds. The owed wake goes into pendingRequests (framework.ts:3157), and the loop's first pass takes them all at once (:13619-13637).
• Store ownership is as described. A start() after stop() is refused for a storePath store (resetCompletedStop, :3569-3575) and allowed for one the caller owns.
• connectome-host (main 3027eafd) creates its framework from storePath and makes a new one on a session switch; it never starts the same instance again. For it, the change is simply that the old framework's timer is gone.
• Diagnostics are as described. inferenceDiagnostics() returns the kept end even after it has passed (:1681-1692); getSleepState() reads null once it has passed (:1864-1868).
• The dispose() test isn't racy. Its getActiveResourcesInfo() counts are taken and checked synchronously.
• Changelog and CI. The fragment's name and format match changelog.d/README.md. CI is green: the four build-and-test jobs, the changelog check and the packed-install check.

_{Method. Two independent passes, then a merge in which every citation was re-read at the head or on main before use.}

• Codex gpt-5.6-sol (reasoning effort xhigh) ran in a read-only sandbox with no network, on a detached worktree at the head, with the merge base and current main as local refs. It took 11 min, 108 shell commands, about 6.0M input tokens (5.8M cached) and 32k output tokens (21k reasoning). Its sandbox refused the tests' temporary directory, so it could not run them.
• Claude Opus 5.5 produced every runtime result above: the head runs, the red-first and mutation runs, the merged-main run and the timer probes. It also did the network-side checks: CI, mergeability, the linked PRs and issues, and connectome-host's main.
• Who found what. R1-1 came from both, in parts: Claude measured the early-fire drop and found the new test's dependence on it; Sol found the over-24.8-day overflow and the existing armAt helper. Both found R1-2 independently. Sol found R1-3 and R1-4; Claude narrowed R1-3's window (by default stop() has no budget). Sol's restart-queue finding moved to "Not counted" (#315), and its overflow finding was folded into R1-1.

Replying to this review.

@Anarchid All four findings are fixed in this push, which also rebases the branch onto main 97ca7eba. The description now matches, and its Tests section has the runs. Below is where each finding went. The two fix commits cite the ids.

R1-1 (b6bea6e2). wakeFromSleep() now arms the rest when its timer fires before sleepUntil, and armSleepWake() arms for min(sleepUntil - now(), MAX_TIMER_MS), with the cap exported from src/deadline-timer.ts. Both read the gate's own now(), as your caveat offered, rather than going through armAt, which reads Date.now(). That keeps one clock, read once per decision. The wake-timing tests now run on node:test's mock timers, so "still ahead" no longer depends on when a real timer fires. A new test sets the gate's clock ten days off Date.now() and then back a second, and fails if the wake follows Date.now() or if the handler drops it. Another checks that a 30-day sleep holds its one timer for 50 ms. Both fail on main.

R1-2 (b6bea6e2, widened in 50987f09). This is the fix you proposed, named agentGone(name). Our internal review found the same gap where an ephemeral run ends, in runEphemeralToCompletion(), and found that a gone agent's pending skip_reply self-wake fires into its name the same way. So agentGone() cancels that agent's self-wake and ends the sleep if that agent set it, and both places an agent leaves call it. Tests cover the idle sweep, stop() and an ephemeral run. The description now says this PR is part of #646, where the question of a fork's sleep holding back the whole gate stays open.

R1-3 (b6bea6e2). It follows your outline. dispose() sets a disposed mark, resumeSleep() clears it, and while it's set neither armSleepWake() nor armSelfWake() arms a timer. A sleep set then is kept for the next start(). A self-wake asked for then isn't kept, since dispose() already drops pending ones (#627). armSelfWake() now returns armed, so the skip_reply log line says when nothing was armed.

R1-4 (b6bea6e2, then f5064bc7). When stop() calls dispose(), the framework tests check that the sleep's wake hasn't fired yet, by reading the gate's own state. If it has, they fail with a message saying this run can't check a sleep kept through a stop. Our internal review pointed out that timing stop() would also fail a slow teardown that kept the sleep, so the check reads the state instead.

Not counted. The description's entry for #315 now says the restart path still only partly works: stop() closes the process queue and start() doesn't open it again, so a restarted lifecycle's tool results are dropped.

This PR ties sleep wakes to the framework’s lifetime and the agent that requested them.

• Sleeping agents wake on the gate's deadline, including across a framework restart.
• Gone agents no longer leave sleep or self-wake timers behind.

Acknowledged by nissa-seru: restart limitations remain under #315, wake persistence across restarts remains under #627, and whether a fork should suppress the whole gate remains under #646. Sleep expiry during stop() before dispose() is intentionally unchanged.
