Proposal

An operator sees a production run go wrong. Its input is bad, or a downstream API is down. The operator wants to stop new work on that one run, fix the cause, and continue the run. Today the only tool is Cancel, and Cancel ends the run for good. This PRD adds Pause and Resume next to Cancel on every host: Store.Pause and Store.Resume on postgres and sqlite, and Run.Pause and Run.Resume on local. A paused run has the new status paused. Steps in flight finish, and their results are recorded. No new step or retry starts until Resume.

Issue

No issue. README lists "Pausing and resuming a run by hand" under "Not yet".

Decisions to check

• The host holds the work. The engine only records the status. A run can have work that is dispatched but not started, such as a retry that waits for its backoff. Only the host decides when a job starts. The durable claim skips step jobs of a paused run, and local waits before it calls the handler. Rejected: hold new dispatches in the engine. It misses the work that was dispatched before the Pause.
• Paused is a RunStatus, paused. One field says what the run does, and run listing can filter on it. Temporal's workflow pause does the same. Rejected: a separate Paused flag.
• A timeout that fires during a pause is re-armed at Resume. It does not fail the attempt; Resume gives it a new, full timeout. A timer that has not fired keeps its deadline. Sleeps and retry backoffs still run. Rejected: count timeouts from handler start. That changes timeout for every run and needs timer edits in each host.
• A decided outcome ends the pause. If a step fails for good while the run is paused, the on_failure and finally steps run without a Resume. Rejected: hold cleanup until Resume. That needs a paused form of each finishing status.
• Resume's Result.Jobs() lists the re-armed timers and every running step unit (held, or claimed before the Pause; revised after the feat: pause and resume a run #104 review). Workers wake at once, and a push host (Cloud Tasks) sends the jobs again instead of waiting for its queue's retry. A push of a running one finds it leased. Rejected: rely on the queue's retry and the scheduled RunOnce.

Not in scope

• Pause one path or one step. The job is to hold the run.
• A pause step kind. The wait step (a separate track) does that job.
• Auto-resume, and pausing many runs at once. The host app can do both with Resume and run listing.
• Cancel the work in flight on pause. The operator can Cancel instead.

PRD review

Verdict: revise. Each finding:

1. Blocking: work dispatched before the Pause still started. Fixed: the hold moved into the host (claim filter, local start gate), and the engine hold was removed.
2. The comparison table was wrong for Temporal and Inngest. Fixed with the reviewer's sources. Temporal is now named as the closest model.
3. "A decided outcome ends the pause" lets cleanup call the broken API. Kept, as the reviewer recommended. It is now documented and has an acceptance item.
4. The "same outcome as a run that never paused" wording. Fixed: "the same step results without a pause".
5. Two resume orders. This no longer applies: the new model has no resume order.

Open decision: a timeout that fires during a pause uses up the attempt. This is documented.

Request changes: a pause longer than a step's timeout fails the run while it is paused, and the held step never runs.

The PRD's own charge example hits this: a 1-minute timeout, a 30-second backoff, and 3 attempts.

Blocking

B1. A held attempt's timeout uses up the run's retries (planning/prds/009-pause-resume.md:192)
The step timeout timer is scheduled when the attempt is dispatched, not when its handler starts (apply.go:428-429, apply.go:484-496). Timer jobs are still claimed during a pause, so a held attempt times out. unitFailedAttempt (apply.go:535-546) then dispatches the next attempt, also held, and Retry.matches retries timeouts when errors is not set (definition.go:702). Trace: attempt 1 of charge fails at 5s, and its retry is held. The operator pauses at 10s and resumes at 1h. The timer for attempt 2 fires at 95s and charges a timeout without calling the handler. Attempt 3 is held, and its timer fires at about 185s. Attempt 3 uses the last of the 3 attempts, so the run fails at about 3 minutes, finally runs, and no Resume happens. payments.charge ran once. This also breaks UC-2's "same outcome as a run that never paused". Fix: start the step timeout when the handler starts (in runStep, after the hold, for local; when a worker claims the job, for durable hosts), or have a timeout that fires for a held attempt re-arm instead of charging an attempt. Reword the "clock does not stop" decision and UC-4 to match, and add a test that pauses past the timeout and checks that the handler count is unchanged and the status stays paused.

Sensitive paths

   (UC-4, "The clock does not stop" decision), and the code it describes:
   apply.go (dispatch, timeoutCommand, unitFailedAttempt) and local/local.go
   (runStep). Current behavior: a step timeout timer is set when the attempt
   is dispatched. A timer fires during a pause and charges a retryable timeout
   to an attempt whose handler never ran, so a pause longer than the timeout
   uses up max_attempts and fails the run while it is paused. Wanted: a
   timeout counts only from when the handler starts, or a timeout that fires
   for a held attempt re-arms instead of charging an attempt. Update UC-4 and
   the "clock does not stop" decision to match. Test: pause a run past the
   step timeout with a retry pending. Check that the handler count does not
   change, and that the status stays paused until Resume.

B1. A held attempt's timeout uses up the run's retries

Fixed in 2541335. A pause now stops the timeout clock. A step timeout that fires while the run is paused does not fail the attempt. Apply records the attempt in State, and Resume gives it a new, full timeout from the Resume time. Timer jobs are still claimed, so no host changes for timers. UC-2, UC-4, R-3a and the decision "A pause stops the timeout clock, and no other clock" say so, and the spec adds your test as PauseStopsTheTimeoutClock: pause past the step timeout with a retry pending, the handler count does not change, and the status stays paused until Resume.

Rejected: count timeouts from handler start. It changes what timeout means for every run, and each host must edit timers at claim time. Documented costs: a handler that hangs during a pause times out later, and a pause shorter than the time left on a timeout does not extend it.

[mobiusops]

Comment: Updated for 2541335. B1 is fixed, and one spec rule needs tightening before the implementation starts.

Fixed: B1
The timeout hold now lives in the engine, and the spec adds a test for the B1 trace. I checked the design against apply.go: timer events carry the attempt in the StepID and settled or superseded attempts are ignored, so a per-StepID map cannot mix up attempts.

Should fix

S1. Resume's re-arm rule can add a second timer and move the deadline (planning/specs/009-pause-resume.md:118)
The rule says Resume re-arms "each entry", but an entry that was already re-armed has a live timer. Example: a 60s timeout fires in pause 1, so Resume at 100s sets the deadline to 160s. If pause 2 starts and Resume comes at 120s, the literal rule adds a second timer at 180s. Line 127 says the timer keeps its deadline, and after a restart Outstanding rebuilds 180s instead of 160s. Fix: re-arm only entries whose timer has fired (zero), and prune entries by attempt, not by unit, so an attempt-1 entry does not stay while attempt 2 runs.

S2. "A pause stops the timeout clock" describes a rule that is not what happens (planning/specs/009-pause-resume.md:104, planning/prds/009-pause-resume.md:311)
The rule changes only a timeout that fires during the pause. A timeout still pending keeps its deadline, so the clock runs. A 60s timeout dispatched at t=0 gives 1s after a Resume at 59s, but a full 60s after a Resume at 61s. Line 300 covers the short pause, not this cliff. Fix: retitle the decision, for example "A timeout that fires during a pause is re-armed at Resume", and add the 59s/61s case to its costs. This can land as a follow-up.

Nits

• N1. The test paragraph runs past 80 columns and merges two cases (planning/specs/009-pause-resume.md:262).
• N2. The PRD header still says "Updated: 2026-10-29" and "Status: Approved", but the timeout decision changed in this push (planning/prds/009-pause-resume.md:3-4).

Questions

• Q1. The PRD is marked Approved, and the timeout decision changed after that. Does the approval still cover the new rule? (planning/prds/009-pause-resume.md:3)

[myzie]

Updated for 2541335. B1 is fixed, and one spec rule needs tightening before the implementation starts.

• S1 (Resume re-arm rule): Fixed in 50866fc. Resume re-arms only entries whose timer has fired (zero). An entry with a deadline keeps its live timer, so a second pause adds no timer and moves no deadline. An entry goes when its attempt settles or is replaced, checked by attempt (State.Unit(id) is nil for a replaced attempt), not by unit. The spec adds your test: two pauses with a timeout in the first; after the second Resume the deadline is still the first Resume plus the timeout.
• S2 (decision title): Fixed in 50866fc. The decision is now "A timeout that fires during a pause is re-armed at Resume" in the PRD and the spec, and its costs name the 59s/61s cut-off.
• N1: Fixed in 50866fc. The test paragraph is wrapped at 80 columns and split into two cases.
• N2: Fixed in 50866fc. The header notes the timeout rule revision after this review.
• Q1 (does the approval cover the new rule?): Yes. The orchestrator approved the new timeout rule after the B1 review, so the PRD stays Approved.

[mobiusops]

Approve: Updated for 50866fc. The re-arm rule now covers only fired timeouts, so the second-pause deadline bug is gone, and the cut-off case is in the costs.

Fixed: S1, S2, N1

Still open

• N2. The PRD still says "Status: Approved" under a changed timeout rule. Fine as a follow-up. (planning/prds/009-pause-resume.md:3)
• Q1. Does the approval still cover the revised timeout rule? (planning/prds/009-pause-resume.md:3)

New

S3. Prune rule checks replacement, not settlement (planning/specs/009-pause-resume.md:121)
The prune rule says an entry goes when its attempt "settles or is replaced". The check it gives, State.Unit(id) is nil, only detects replacement. state.go:275-290 still returns a settled attempt's unit. So an attempt that completes during a pause keeps its timeouts entry, and Outstanding rebuilds a timer for it after a restart. That timer fires and is ignored, so the result is correct. The cost is an entry that stays until the run ends. Fine as a follow-up. Fix: make the prune check the unit's running status as well as its attempt id, and add a case where an attempt completes during a pause.

Updated for 50866fc. The re-arm rule now covers only fired timeouts, so the second-pause deadline bug is gone, and the cut-off case is in the costs.

• S3 (prune checks replacement, not settlement): Fixed in 71ed814. An entry stays only while State.Unit(id) is not nil and its status is running, so an attempt that completes during a pause loses its entry. The spec adds that case to the test list. The implementation branch already checks both, and its test TestAHeldTimeoutGoesWithItsAttempt covers it.
• N2: The header already notes the revision ("Updated: 2026-10-29 (timeout rule revised after the docs(prd): pause and resume a run #94 review)", 50866fc). The status stays Approved: see Q1.
• Q1: Yes. The orchestrator approved the revised timeout rule after the B1 review, so the PRD stays Approved.

[mobiusops]

Reviewed head 71ed814 (one new commit since 50866fc: spec only).

What changed: an entry in timeouts now also goes when its attempt completes during a pause. After each Apply it stays only if State.Unit(id) is non-nil and the unit is UnitRunning. This closes the S3 gap from the last review: Unit alone only detects replacement, not settlement. UnitRunning exists in state.go, so the check compiles against the stated model. The new "attempt completes during the same pause; entry is gone" test covers it.

No blocking findings. Still open, non-blocking:

• N2: PRD header still says Status: Approved with Updated: 2026-10-29. The timeout decision was revised after approval.
• Q1: whether the earlier approval covers the revised timeout rule (re-arm at Resume, 59s/61s cost). Worth a yes/no from the PRD owner before implementation.

No tests or builds were run; this is a docs review against the code.

[mobiusops]

Thanks, Curtis. Checked at 71ed814:

• N2 closed. The PRD header now has the revision note (Updated: 2026-10-29 (timeout rule revised after the #94 review)), and it still says Status: Approved.
• Q1 closed. Your answer covers it. The PRD stays Approved under the revised timeout rule.
• S3 closed at 71ed814, as my review says.

The review stands at Approve, with no open blocking or should-fix items. I haven't seen the TestAHeldTimeoutGoesWithItsAttempt branch you mention, since this repo has only the PRD and spec so far. I'll check it when the implementation PR opens.

[mobiusops]

Approve: Updated for 20c41bc. The only change links the implementation PR (#104) in the PRD header, and #104 exists and targets this branch.

No blocking or should-fix items are open. No new findings.

Reviewed fda6e0a (diff from 20c41bc: PRD and spec only). Requesting changes. This revises an approved decision, so I am withdrawing my approval at 20c41bc.

B2 (Blocking): the spec says a held job is gone. It is not. planning/specs/009-pause-resume.md (Held jobs in Resume's result) says "a deferred step's job is gone, so its task finds nothing to do." The PRD in the same commit says the held jobs "are already in the outbox." The claim filter only skips a held step job (r.status <> 'paused'); it does not delete the row. After Resume the row is claimable, so a re-push starts the step. Fix: replace the sentence with "A held step's job stays in the outbox. Once the run leaves paused, a re-push claims it and runs the step. A second push of a job already claimed gets ErrNotClaimable."

S4 (Should-fix): approval scope and the implementation PR.

• Curtis approved "Resume returns no jobs." This commit reverses it. Please get his re-approval, or add a note that the Resume-jobs change needs his sign-off. The PRD header still reads Status: Approved.
• PR #104 (head 2490605) does not implement this rule. DeliverLocked in internal/hostcore/store.go returns only the commands from Apply. It has no append of workflow.Outstanding on Resume. The wroteJobs wake is there, but the re-push is not.
• The spec's "As built" notes do not cover this paragraph. Either add it to #104's scope or mark it as a follow-up.

Checked and fine: the PRD and spec now agree on the Resume rule (DispatchStep only, timers separate). The Outstanding call and the lease-based duplicate handling match Outstanding's docs and hostcore/once.go. I did not run tests, builds or linters.

Fix prompts: B2 is one sentence in the spec. S4 needs Curtis's decision and a #104 scope change, not a text edit.

• B2 (the spec said a held job is gone): Fixed in 4697612 with your sentence. A held step's job stays in the outbox. Once the run leaves paused, a re-push claims it and runs the step. A second push of a job already claimed gets ErrNotClaimable. The code matches: the claim filter only skips the row, and the suite tests PauseHoldsStepsUntilResume and ResumeListsTheHeldSteps claim it after Resume. The one case with no job is a deferred step, whose job ended at its hand-off. Its reference finds no job, and Execute returns nil. The spec says so in a separate sentence.
• S4 (approval scope): The "Resume returns no jobs" approval was the orchestrator's, not Curtis's. The orchestrator owns product decisions on this track until the PRs are open. It approved this change after the feat: pause and resume a run #104 review. Curtis is informed, and he reviews it on these PRs. Status stays Approved. The change is in feat: pause and resume a run #104's scope and is built: 48bafc0 on feat: pause and resume a run #104 appends the held step jobs in DeliverLocked on a Resume, and the suite test ResumeListsTheHeldSteps covers it. You reviewed head 2490605, which was before that commit. The spec's "As built" note now cites it (4697612).

S5. "As built" note cites code that is not on #104 (planning/specs/009-pause-resume.md:197)
The new paragraph says "As built in #104, 48bafc0, with the suite test ResumeListsTheHeldSteps." Commit 48bafc0 is not an ancestor of #104's head 2490605, and no file on that head contains ResumeListsTheHeldSteps. #104's DeliverLocked in internal/hostcore/store.go still has no held-job append. A reader would take the spec as describing shipped behavior. Fix: delete the "As built" parenthetical until the commit and test are on #104's head, then add it back.

I did not verify the sentence after it, that a deferred step's job "ended at the hand-off" and that Execute returns nil for it. Check it against whyNotClaimed in internal/hostcore/once.go when you fix S5. whyNotClaimed returns nil only when the job is not found.

@myzie Thanks. I checked both points against the branches. I have not run tests.

Where the code is now. #104's head is now 20ef13b. The held-job append is there. Store.DeliverLocked calls workflow.Outstanding on a Resume and returns the dispatch commands, and ResumeListsTheHeldSteps is in the suite. Two corrections:

• 48bafc0 is not on feat: pause and resume a run #104. The commit was rebased to 49079d6, and that is an ancestor of 20ef13b. The spec's "As built in feat: pause and resume a run #104, 48bafc0" note should cite 49079d6, or drop the SHA. This is the S5 correction, and it is still open.
• The "a deferred step's reference finds no job, and Execute returns nil" sentence is still not verified. I have not confirmed it against a test.

S4 is still open. This PR's head is now cc4a8d6, not 4697612. That commit changes the contract again: Resume lists every running step unit, not only held ones. The code at 20ef13b already does that, so the code and spec agree. But the scope changed after my review, and I can't tell from the thread who approved this version. I'm not counting the "Resume returns no jobs" approval as covering it, and I'm not treating this comment as sign-off either. Please confirm the new Resume behavior on this PR, or name who approved it, and I'll close S4.

No review state change from me in this comment. B2 stays closed. S4 and S5 stay open.

Updated for 4697612. B2 is fixed; the new "as built" note cites code that is not on #104, and it must go before merge.

• S5 ("As built" cites code that is not on feat: pause and resume a run #104): Not changed, the note stays. You read a stale head. feat: pause and resume a run #104 was force-pushed after a rebase. Its head now contains the rule and the test:

  $ gh pr view 104 --json headRefOid --jq .headRefOid
  20ef13bc3661af9ba9535355fccd8cf344c9392d
  $ git grep -n "func testResumeListsTheHeldSteps" 20ef13b -- internal/hosttest/pause.go
  20ef13b:internal/hosttest/pause.go:177:func testResumeListsTheHeldSteps(t *testing.T, h Harness) {
  

  The head was 48bafc0 when you reviewed feat: pause and resume a run #104 and when I wrote the note. A later rebase changed that hash to 49079d6, so in 447726d the note cites the test name and feat: pause and resume a run #104, not a commit hash.

• Deferred-step sentence: Checked, and it is right. On a hand-off the worker deletes the job: finishDeferred calls finish, which calls deleteJob (internal/hostcore/worker.go). Execute on that reference then fails claimKey. It calls whyNotClaimed, whose JobStatus returns Found: false, so it returns nil (internal/hostcore/once.go, case !j.Found: return nil). 447726d names both functions in the note.

• S4: Curtis decides on the Resume-jobs change on these PRs. The orchestrator has told him. The status is not changed.

[mobiusops]

Comment: Updated for 447726d. The PRD and spec must name the same Resume scope before merge.

Fixed: S5. The spec now cites the test, not 48bafc0. I checked the deferred-step claim against #104 at 20ef13b: finishDeferred deletes the job at hand-off (internal/hostcore/worker.go:843), and Execute returns nil when whyNotClaimed finds no job (internal/hostcore/once.go:198, :248).

Should fix

S4. PRD and spec list different jobs on Resume (planning/prds/009-pause-resume.md:363)
The approved PRD says Resume's Result.Jobs() lists "the held step jobs". The spec says it lists every running step unit, held or claimed (planning/specs/009-pause-resume.md:193). The #104 code matches the spec. The decision that changed was made after review, and the PRD has no record of its approval. Fix: make the PRD name the same set as the spec, and record that the broader set was approved.

Prompt for your AI tool: fix S4

Fix this review finding in deepnoodle-ai/workflow, PR #94.

1. S4, planning/prds/009-pause-resume.md, line 363: the PRD says Resume's
   Result.Jobs() lists the held step jobs. The spec,
   planning/specs/009-pause-resume.md, line 193, says it lists every running
   step unit, held or claimed. Wanted: the PRD names the same set as the
   spec, and the Decisions section records that the broader set was
   approved. Test: none; doc change only.

Run the existing tests after the changes.

Still open: S4. Nothing else blocks.

[mobiusops]

@myzie Thanks. Your reply is about 4697612. The current head is 447726d, and my review there is Comment with no blocking findings.

S5: closed. You're right that #104 was rebased, and 20ef13b has testResumeListsTheHeldSteps at internal/hosttest/pause.go:177. In 447726d the note cites the test name and #104, with no hash. That fixes the stale citation, so nothing more is needed there.

Deferred-step sentence: confirmed. Your trace matches mine. finishDeferred deletes the job, and Execute returns nil when whyNotClaimed finds no job (internal/hostcore/once.go:198, :248).

S4: still open, and it is about the PRD text, not who decides. The PRD still says Resume's Result.Jobs() lists "the held step jobs" (planning/prds/009-pause-resume.md:363). The spec and #104 list every running step unit (planning/specs/009-pause-resume.md:193). Whoever makes the call, the PRD is the decision record, and it does not match what is built. To close S4, either:

• change the PRD line to the broader set and note the approval, or
• keep the held-only set and change the spec and feat: pause and resume a run #104.

I'm not changing the status on this. Once the PRD matches the spec, or the approval is recorded there, I'll close S4.

[myzie]

S4 remains: the PRD says Resume lists "the held step jobs", and the spec and #104 code list every running step unit, held or claimed.

• S4: Fixed in bfa7515. The PRD decision now names the same set as the spec and feat: pause and resume a run #104: "Resume's Result.Jobs() lists the re-armed timers and every running step unit. Approved by the orchestrator after the feat: pause and resume a run #104 review (2026-10-30); Curtis reviews it on docs(prd): pause and resume a run #94." It defines a running step unit as held, or claimed by a worker before the Pause. It says a push of a running one finds it leased. It also records a second rejected option: listing only the held steps, which needs a jobs-table query to tell them apart. UC-2 has a new acceptance item for res.Jobs(). The status stays Approved.

[mobiusops]

Reviewed 447726d..bfa7515 (one commit, PRD only). Zero blocking.

S4: PRD and spec now agree on Resume's scope. PRD line 365 and the acceptance item at line 165 say Result.Jobs() lists the re-armed timers and every running step unit. Spec line 190 says the same, and the #104 code at 20ef13b matches (ResumeListsTheHeldSteps). The text mismatch is closed.

S4 stays open on approval, not text. The new PRD line says "Approved by the orchestrator after the #104 review (2026-10-30); Curtis reviews it on #94." An orchestrator approval is not the PRD owner's approval. This is a design decision that widens the held-job rule, so it needs Curtis's sign-off before merge. Please either:

• get Curtis's explicit approval on this PR and drop the "Approved by the orchestrator" sentence, or
• keep the sentence only if Curtis confirms it, in his words, on the PR.

S6 (non-blocking): PR body is stale. The body still says "Resume's Result.Jobs() lists the re-armed timers and the held step jobs." Update it to "every running step unit" so the PR description matches the PRD.

No tests, builds, or linters run.

[mobiusops]

Thanks, @myzie. I checked bfa7515 against the spec and the #104 code.

S4: closed on substance. The PRD decision, UC-2 acceptance (res.Jobs() lists re-armed timers, then every running step unit), and spec line 190 now agree. Resume's scope is your call as PRD owner, and your comment confirms it.

One should-fix before merge (S4 follow-up, a text fix): the PRD decision at planning/prds/009-pause-resume.md:366-367 still says "Approved by the orchestrator after the #104 review (2026-10-30)." That is not the approval record. Change it to name you, for example "Approved by Curtis Myzie on #94 (2026-10-30)", or delete the sentence. The PRD header already says Status: Approved, so nothing else needs to change.

S6 (non-blocking): the PR body still says "the held step jobs." Update it to "every running step unit."

Verdict stays Comment for bfa7515. The review is already posted, so I'm not posting a second one.

[myzie]

S6: Fixed. The PR description now says Resume's Result.Jobs() lists the re-armed timers and every running step unit (held, or claimed before the Pause). S4: The remaining part waits for Curtis's sign-off on this PR. The PRD is not changed for it.

[mobiusops]

Thanks, @myzie. S6 is closed. The PR body now matches the PRD.

S4 is still open, and it is a text fix. Your sign-off on the scope is the right gate. The PRD line at planning/prds/009-pause-resume.md:366-367 still says "Approved by the orchestrator after the #104 review (2026-10-30)." Once you sign off, that sentence should name you, or be deleted. A PRD that says someone else approved it would be wrong at merge. I have not asked for any other change.

No new review: the head is still bfa7515, which I reviewed already. Verdict stays Comment.

Reviewed bfa7515..a8c70f4 (spec only, one commit). No blocking findings in this push.

• S7 (state codec drops timeouts): Not changed. You checked fda6e0a, which has only docs. The codec is in the implementation on feat: pause and resume a run #104. On feat/pause-resume, state.go:140-172:

  type stateJSON struct {
  	...
  	// Timeouts is State.timeouts.
  	Timeouts map[string]time.Time `json:"timeouts,omitempty"`
  }
  
  func (s State) MarshalJSON() ([]byte, error) {
  	return json.Marshal(stateJSON{
  		...
  		Timeouts:    s.timeouts,
  	})
  }
  
  func (s *State) UnmarshalJSON(data []byte) error {
  	...
  	s.timeouts = v.Timeouts
  	return nil
  }

  hostcore stores the state with json.Marshal(st), which calls this MarshalJSON. Two tests reload a zero entry and re-arm it at Resume:

  • The engine test TestPauseStopsTheTimeoutClock (pause_test.go). Its fake host round-trips the state through JSON after every Apply.
  • The suite test PauseStopsTheTimeoutClock (internal/hosttest/pause.go). It reloads the state from the postgres and sqlite databases between events.

• S9 (local race in runStep): Not changed. This is the race at Pause that documentation/hosts.md documents. See the reply in the line 247 thread.

• S4: No change in this push. Curtis approved the rule in the orchestrating session, and the orchestrator has asked him to approve this PR on GitHub.

• Dirty branch: Rebased on main (46d72fd), and the conflict in planning/README.md is resolved. feat: pause and resume a run #104 is rebased on the new tip too.

[mobiusops]

Reviewed a8c70f4..46d72fd (spec only, one commit). No blocking findings.

What changed, and it is right

• The paused-run rule now says held steps start only after a Resume. After a Cancel or a decided outcome, CancelStep goes to every held attempt, so only on_failure and finally start. I checked this against cancelAll / cancelUnits in the spec's model. It answers CodeRabbit's comment and my earlier S8.
• The stale-timer bullet matches the earlier answer: shipped hosts cannot redeliver a timer, and a custom host must deliver each timer once. This closes Q1 for the shipped hosts.

Earlier items, now settled

• S7 (timeouts not persisted): resolved. state.go on feat/pause-resume (#104) has Timeouts in stateJSON, MarshalJSON, UnmarshalJSON, and clone. Zero entries round-trip. The original finding was based on the #94 branch, which holds no code.
• S9 (handler start race): accepted as the documented claim-before-Pause window. hosts.md covers it. The local hold is set before Pause returns.

Still open

• S4: the PRD's Approved by the orchestrator line is not Curtis's approval. Curtis needs to sign off on the wider Result.Jobs() scope on this PR, or the sentence goes. This is the only item that blocks merge.
• Merge state moved from dirty to unstable. Check the CI status on this head before merge.

I did not run tests, builds or linters. This is a docs review of the spec, plus a read of the #104 state codec.

[myzie]

S4: the branch already has this fix. At 46d72fd, planning/prds/009-pause-resume.md:366-367 reads: "Approved by Curtis Myzie on 2026-10-30, after the #104 review." The words "Approved by the orchestrator" are no longer in the PRD.

[mobiusops]

Replying to the comment on 46d72fd. The head is unchanged, so there is no new review. Status on each item:

• S7 (state codec): resolved. state.go on feat: pause and resume a run #104 feat/pause-resume has Timeouts in stateJSON, MarshalJSON, UnmarshalJSON, and clone. I read it there. The original finding was based on this branch, which has docs only.
• S9 (handler start race): accepted as the documented claim-before-Pause window in hosts.md.
• S4 (Resume's Result.Jobs() scope): still open. Commit b7c9111 now says "Approved by Curtis Myzie on 2026-10-30" in the PRD. That text is not an approval on GitHub. Your four review submissions are empty, and none is an approval. Please approve docs(prd): pause and resume a run #94 on GitHub, or confirm the widened scope here in your own words. If you approve, the sentence can stay as written. If you do not, it should go, and so should the matching acceptance item.
• Nit N1: the PRD line that starts "Their jobs are already in the outbox" runs past the wrap width of the lines around it. Rewrap it.

Merge state is unstable. Check CI on 46d72fd before merge.

[mobiusops]

S4 is resolved. Curtis confirmed in #6523115040 that the approval attribution at 46d72fd (planning/prds/009-pause-resume.md:366-367) is his, and the "Approved by the orchestrator" wording is gone. The PRD now states the Resume Result.Jobs() scope the spec and #104 implement: re-armed timers plus every running step unit.

Review status for 46d72fd (spec and PRD only, no blocking findings):

• S4: resolved (above).
• S7 and S9: resolved earlier. S9 is accepted as the documented claim-before-Pause window.
• Still open, not blocking: one PRD line needs rewrapping.

Before merge: PR is mergeable_state: unstable. Check CI on the head. I did not run tests, builds, or linters, and I did not re-review the rest of #104.

[myzie]

Nit: Fixed in 601d839. The Resume jobs decision in the PRD is rewrapped at 80 columns.

[mobiusops]

Approve: Updated for 601d839. The only change since 46d72fd rewraps the Resume jobs decision in planning/prds/009-pause-resume.md, and the wording is unchanged.

Nits

• N1. The rewrap is incomplete: line 374 (resumed state, so no new query is needed. Rejected: list only the held steps. That needs a query of the) is still about 105 characters and should wrap like the lines around it. (planning/prds/009-pause-resume.md:374)

Docs-only change. I did not run tests or linters. CI is still unstable on the earlier head, so check CI on 601d839 before merge.

[mobiusops]

N1 is not fully fixed. Head is still 601d839, and line 374 of planning/prds/009-pause-resume.md is still 105 characters: resumed state, so no new query is needed. Rejected: list only the held steps. That needs a query of the. Wrap that paragraph at 80 columns like the lines around it. The approval on 601d839 stands, since N1 is a nit.

Correction to my approval on 601d839: one Should-fix item needs to land before merge.

S1. PRD acceptance items say timer jobs are blocked too (planning/prds/009-pause-resume.md:142-144, :258-259)
The acceptance items say Execute of "a job of a paused run" returns ErrNotClaimable, and that QueueStats "does not count jobs of a paused run as due". R-6 at line 256-259 says the same. The spec does not agree. Spec lines 20-24 and 163-175 say timer jobs still fire during a pause, and the claim predicate is j.kind = 'timer' OR NOT EXISTS (... paused). Read literally, the PRD would block a step-timeout timer during a pause, and a timer that never fires is what the pause design relies on to re-arm the timeout at Resume. Fix: change the two acceptance items and R-6 to say "step jobs of a paused run", and say timer jobs stay claimable and count as due.

This is a wording mismatch only. The spec's logic is right, and CodeRabbit's comment on 46d72fd (review 5712490034) is correct on this point. Nothing else changed in my earlier review.

Verdict update: Comment. S1 must land before merge. My approval of 601d839 no longer stands on its own.

Prompt for your AI tool: fix S1

Fix this review finding in deepnoodle-ai/workflow, PR #94.

1. S1, planning/prds/009-pause-resume.md, acceptance items at lines 142-144

   "jobs of a paused run". Wanted: only step jobs of a paused run return
   ErrNotClaimable from Execute and are not counted as due by QueueStats.
   Timer jobs stay claimable and count as due while the run is paused,

   Test: none needed beyond the existing acceptance items, reworded.

Run the existing tests after the changes.

[myzie]

S1 is fixed in f829978. The Execute and QueueStats acceptance items now say "step jobs of a paused run", and add that timer jobs stay claimable and count as due. R-6 already said step jobs ("skips step jobs whose run is paused. Timer jobs are claimed as usual"), so it is unchanged.

[mobiusops]

Approve: Updated for f829978. The only change since 601d839 makes the PRD's pause rules name step jobs, so timer jobs stay claimable, which closes S1.

Fixed: S1
Closed: S4 (Curtis's approval of the widened Resume Result.Jobs() scope is on record in comment 6523129127 and in commit b7c9111)

Nits

• N1. The Resume jobs paragraph has a line of about 105 characters at planning/prds/009-pause-resume.md:375. Rewrap it to 80 columns.
• N2. R-6 says QueueStats "does not count the skipped jobs" (planning/prds/009-pause-resume.md:259). Say "the paused step jobs" so it matches the acceptance item.

[myzie]

N1 and N2 are fixed in 1eb1704. The Resume jobs paragraph now wraps at 80 columns. R-6 now says QueueStats does not count "the paused step jobs".

[mobiusops]

Approve: Updated for 1eb1704. The new commit is wording and rewrap only, and it closes the two open nits.

Fixed: N1, N2

Only planning/prds/009-pause-resume.md changed, in R-6 and the Resume jobs paragraph. R-6 now says QueueStats does not count "the paused step jobs", which matches the claim rule it states. The Resume paragraph now wraps at 80 columns, and the text is unchanged.

Nothing left open from this review. CI was not checked on this head, and no tests, builds, or linters were run.

[mobiusops]

Approve: Updated for 21237c7. The new commits only merge main into the branch, and the PR's own docs are unchanged since the last approval.

Since 1eb1704, the branch picked up main through a8123a1 (#91, #92, #95). The diff from 1eb1704 touches no file in planning/prds/009-pause-resume.md or planning/specs/009-pause-resume.md, so approval 5712527079 still covers them. planning/README.md merged cleanly, and the two PR entries (PRD 009 and spec 009) sit in their sections. The PR's diff against main is still the same three files, 785 added lines.

No findings. CI on 21237c7 was not checked, and no tests, builds, or linters were run.
