Manual backport of #3700 (cherry-pick 9b1b8c71) to stable. The automated job could not do it: every Backport to stable run since 2026-08-21 18:31 fails because the AI Gateway key is over its budget (API key budget exceeded. Current spend: $10001.21, limit: $10000.00), including the forced workflow_dispatch run, which resolved the SHA and cherry-picked correctly before dying at conflict resolution.

Stacked on #3718 (backport of #3406), which this commit cannot terminate without. Merge that first; this PR's diff is against it.

Why the prerequisite

#3700's turnstile waits on any lower armed barrier, a wider relation than gatesOn, and its deadlock-freedom argument rests on #3406 having removed computeResolvesOnItsOwn's unconditional step -> true shortcut. Cherry-picked onto plain stable, this commit's own turnstile termination pin fails with Unconsumed event: step_created: the step spinner is reported self-resolving, so hasParkedCommittedDelivery blocks the dispenser and the parked chain never opens.

Adaptations

  • workflow.ts: stable has no generateUlid const and installs the raw ulid factory as the STABLE_ULID global (upstream installs the counting generateUlid). Wrapped as countingUlid(seedTime?), preserving the factory signature, so mintCount counts every draw from the run's sequence including serialization-driven stream ids (the termination argument for quiesceEarlierCascades depends on that) without changing which seed time stream ids get on stable.
  • private.ts: the gatesOn doc hunk carries over via [core] Keep step results ordered behind waits parked on unread hook payloads (#3406) (backport to stable) #3718. isLogOrderDrawsEnabled, quiescenceTurn, quiesceEarlierCascades and awaitEarlierDeliveries are byte-identical to main.
  • test-support/orchestrator-context.ts does not exist on stable (that extraction is main-only) and is dropped. The mintCount wiring it carries applies to the local setupWorkflowContext copies in the four test files the commit already touches, which is where the cherry-pick put it.
  • docs/content/docs/v5/configuration/runtime-tuning.mdx does not exist on stable, whose docs tree has no v5/configuration directory. Dropped, matching Backport #3554: [core] Pin draw order to event-log order: retire delivery barriers through one ordered dispenser #3629 which carried no docs files for the same reason. WORKFLOW_LOG_ORDER_DRAWS stays documented on main.
  • .gitignore: took only this commit's addition (the e2e-diagnostics-*.json sidecar entry, whose writer does exist on stable), not the main-only event-log-race-repro-* block the conflict dragged in.
  • Changeset downgraded minor -> patch for the maintenance line, matching Backport #3554: [core] Pin draw order to event-log order: retire delivery barriers through one ordered dispenser #3629.

Verification

Not run locally: the e2e lanes (they need a built workbench) and the Event Log Race Repro lane, which is the measurement that matters for this change. CI on this PR is the check.

Converting to draft so we can confirm that it doesn't cause regression in main beta branch before we re confident about rolling this backport over to stable

Converting to draft so we can confirm that it doesn't cause regression in main beta branch before we re confident about rolling this backport over to stable

Manual backport of #3700 (cherry-pick 9b1b8c71) to stable. The automated job could not do it: every Backport to stable run since 2026-08-21 18:31 fails because the AI Gateway key is over its budget (API key budget exceeded. Current spend: $10001.21, limit: $10000.00), including the forced workflow_dispatch run, which resolved the SHA and cherry-picked correctly before dying at conflict resolution.
Stacked on #3718 (backport of #3406), which this commit cannot terminate without. Merge that first; this PR's diff is against it.
Why the prerequisite
#3700's turnstile waits on any lower armed barrier, a wider relation than gatesOn, and its deadlock-freedom argument rests on #3406 having removed computeResolvesOnItsOwn's unconditional step -> true shortcut. Cherry-picked onto plain stable, this commit's own turnstile termination pin fails with Unconsumed event: step_created: the step spinner is reported self-resolving, so hasParkedCommittedDelivery blocks the dispenser and the parked chain never opens.
Adaptations
  • workflow.ts: stable has no generateUlid const and installs the raw ulid factory as the STABLE_ULID global (upstream installs the counting generateUlid). Wrapped as countingUlid(seedTime?), preserving the factory signature, so mintCount counts every draw from the run's sequence including serialization-driven stream ids (the termination argument for quiesceEarlierCascades depends on that) without changing which seed time stream ids get on stable.
  • private.ts: the gatesOn doc hunk carries over via [core] Keep step results ordered behind waits parked on unread hook payloads (#3406) (backport to stable) #3718. isLogOrderDrawsEnabled, quiescenceTurn, quiesceEarlierCascades and awaitEarlierDeliveries are byte-identical to main.
  • test-support/orchestrator-context.ts does not exist on stable (that extraction is main-only) and is dropped. The mintCount wiring it carries applies to the local setupWorkflowContext copies in the four test files the commit already touches, which is where the cherry-pick put it.
  • docs/content/docs/v5/configuration/runtime-tuning.mdx does not exist on stable, whose docs tree has no v5/configuration directory. Dropped, matching Backport #3554: [core] Pin draw order to event-log order: retire delivery barriers through one ordered dispenser #3629 which carried no docs files for the same reason. WORKFLOW_LOG_ORDER_DRAWS stays documented on main.
  • .gitignore: took only this commit's addition (the e2e-diagnostics-*.json sidecar entry, whose writer does exist on stable), not the main-only event-log-race-repro-* block the conflict dragged in.
  • Changeset downgraded minor -> patch for the maintenance line, matching Backport #3554: [core] Pin draw order to event-log order: retire delivery barriers through one ordered dispenser #3629.
Verification
Not run locally: the e2e lanes (they need a built workbench) and the Event Log Race Repro lane, which is the measurement that matters for this change. CI on this PR is the check.

Converting to draft so we can confirm that it doesn't cause regression in main beta branch before we re confident about rolling this backport over to stable

Manual backport of #3700 (cherry-pick 9b1b8c71) to stable. The automated job could not do it: every Backport to stable run since 2026-08-21 18:31 fails because the AI Gateway key is over its budget (API key budget exceeded. Current spend: $10001.21, limit: $10000.00), including the forced workflow_dispatch run, which resolved the SHA and cherry-picked correctly before dying at conflict resolution.
Stacked on #3718 (backport of #3406), which this commit cannot terminate without. Merge that first; this PR's diff is against it.
Why the prerequisite
#3700's turnstile waits on any lower armed barrier, a wider relation than gatesOn, and its deadlock-freedom argument rests on #3406 having removed computeResolvesOnItsOwn's unconditional step -> true shortcut. Cherry-picked onto plain stable, this commit's own turnstile termination pin fails with Unconsumed event: step_created: the step spinner is reported self-resolving, so hasParkedCommittedDelivery blocks the dispenser and the parked chain never opens.
Adaptations
  • workflow.ts: stable has no generateUlid const and installs the raw ulid factory as the STABLE_ULID global (upstream installs the counting generateUlid). Wrapped as countingUlid(seedTime?), preserving the factory signature, so mintCount counts every draw from the run's sequence including serialization-driven stream ids (the termination argument for quiesceEarlierCascades depends on that) without changing which seed time stream ids get on stable.
  • private.ts: the gatesOn doc hunk carries over via [core] Keep step results ordered behind waits parked on unread hook payloads (#3406) (backport to stable) #3718. isLogOrderDrawsEnabled, quiescenceTurn, quiesceEarlierCascades and awaitEarlierDeliveries are byte-identical to main.
  • test-support/orchestrator-context.ts does not exist on stable (that extraction is main-only) and is dropped. The mintCount wiring it carries applies to the local setupWorkflowContext copies in the four test files the commit already touches, which is where the cherry-pick put it.
  • docs/content/docs/v5/configuration/runtime-tuning.mdx does not exist on stable, whose docs tree has no v5/configuration directory. Dropped, matching Backport #3554: [core] Pin draw order to event-log order: retire delivery barriers through one ordered dispenser #3629 which carried no docs files for the same reason. WORKFLOW_LOG_ORDER_DRAWS stays documented on main.
  • .gitignore: took only this commit's addition (the e2e-diagnostics-*.json sidecar entry, whose writer does exist on stable), not the main-only event-log-race-repro-* block the conflict dragged in.
  • Changeset downgraded minor -> patch for the maintenance line, matching Backport #3554: [core] Pin draw order to event-log order: retire delivery barriers through one ordered dispenser #3629.
Verification
Not run locally: the e2e lanes (they need a built workbench) and the Event Log Race Repro lane, which is the measurement that matters for this change. CI on this PR is the check.

Converting to draft so we can confirm that it doesn't cause regression in main beta branch before we re confident about rolling this backport over to stable

Manual backport of #3700 (cherry-pick 9b1b8c71) to stable. The automated job could not do it: every Backport to stable run since 2026-08-21 18:31 fails because the AI Gateway key is over its budget (API key budget exceeded. Current spend: $10001.21, limit: $10000.00), including the forced workflow_dispatch run, which resolved the SHA and cherry-picked correctly before dying at conflict resolution.
Stacked on #3718 (backport of #3406), which this commit cannot terminate without. Merge that first; this PR's diff is against it.
Why the prerequisite
#3700's turnstile waits on any lower armed barrier, a wider relation than gatesOn, and its deadlock-freedom argument rests on #3406 having removed computeResolvesOnItsOwn's unconditional step -> true shortcut. Cherry-picked onto plain stable, this commit's own turnstile termination pin fails with Unconsumed event: step_created: the step spinner is reported self-resolving, so hasParkedCommittedDelivery blocks the dispenser and the parked chain never opens.
Adaptations
  • workflow.ts: stable has no generateUlid const and installs the raw ulid factory as the STABLE_ULID global (upstream installs the counting generateUlid). Wrapped as countingUlid(seedTime?), preserving the factory signature, so mintCount counts every draw from the run's sequence including serialization-driven stream ids (the termination argument for quiesceEarlierCascades depends on that) without changing which seed time stream ids get on stable.
  • private.ts: the gatesOn doc hunk carries over via [core] Keep step results ordered behind waits parked on unread hook payloads (#3406) (backport to stable) #3718. isLogOrderDrawsEnabled, quiescenceTurn, quiesceEarlierCascades and awaitEarlierDeliveries are byte-identical to main.
  • test-support/orchestrator-context.ts does not exist on stable (that extraction is main-only) and is dropped. The mintCount wiring it carries applies to the local setupWorkflowContext copies in the four test files the commit already touches, which is where the cherry-pick put it.
  • docs/content/docs/v5/configuration/runtime-tuning.mdx does not exist on stable, whose docs tree has no v5/configuration directory. Dropped, matching Backport #3554: [core] Pin draw order to event-log order: retire delivery barriers through one ordered dispenser #3629 which carried no docs files for the same reason. WORKFLOW_LOG_ORDER_DRAWS stays documented on main.
  • .gitignore: took only this commit's addition (the e2e-diagnostics-*.json sidecar entry, whose writer does exist on stable), not the main-only event-log-race-repro-* block the conflict dragged in.
  • Changeset downgraded minor -> patch for the maintenance line, matching Backport #3554: [core] Pin draw order to event-log order: retire delivery barriers through one ordered dispenser #3629.
Verification
Not run locally: the e2e lanes (they need a built workbench) and the Event Log Race Repro lane, which is the measurement that matters for this change. CI on this PR is the check.

Converting to draft so we can confirm that it doesn't cause regression in main beta branch before we re confident about rolling this backport over to stable

Manual backport of #3700 (cherry-pick 9b1b8c71) to stable. The automated job could not do it: every Backport to stable run since 2026-08-21 18:31 fails because the AI Gateway key is over its budget (API key budget exceeded. Current spend: $10001.21, limit: $10000.00), including the forced workflow_dispatch run, which resolved the SHA and cherry-picked correctly before dying at conflict resolution.
Stacked on #3718 (backport of #3406), which this commit cannot terminate without. Merge that first; this PR's diff is against it.
Why the prerequisite
#3700's turnstile waits on any lower armed barrier, a wider relation than gatesOn, and its deadlock-freedom argument rests on #3406 having removed computeResolvesOnItsOwn's unconditional step -> true shortcut. Cherry-picked onto plain stable, this commit's own turnstile termination pin fails with Unconsumed event: step_created: the step spinner is reported self-resolving, so hasParkedCommittedDelivery blocks the dispenser and the parked chain never opens.
Adaptations
  • workflow.ts: stable has no generateUlid const and installs the raw ulid factory as the STABLE_ULID global (upstream installs the counting generateUlid). Wrapped as countingUlid(seedTime?), preserving the factory signature, so mintCount counts every draw from the run's sequence including serialization-driven stream ids (the termination argument for quiesceEarlierCascades depends on that) without changing which seed time stream ids get on stable.
  • private.ts: the gatesOn doc hunk carries over via [core] Keep step results ordered behind waits parked on unread hook payloads (#3406) (backport to stable) #3718. isLogOrderDrawsEnabled, quiescenceTurn, quiesceEarlierCascades and awaitEarlierDeliveries are byte-identical to main.
  • test-support/orchestrator-context.ts does not exist on stable (that extraction is main-only) and is dropped. The mintCount wiring it carries applies to the local setupWorkflowContext copies in the four test files the commit already touches, which is where the cherry-pick put it.
  • docs/content/docs/v5/configuration/runtime-tuning.mdx does not exist on stable, whose docs tree has no v5/configuration directory. Dropped, matching Backport #3554: [core] Pin draw order to event-log order: retire delivery barriers through one ordered dispenser #3629 which carried no docs files for the same reason. WORKFLOW_LOG_ORDER_DRAWS stays documented on main.
  • .gitignore: took only this commit's addition (the e2e-diagnostics-*.json sidecar entry, whose writer does exist on stable), not the main-only event-log-race-repro-* block the conflict dragged in.
  • Changeset downgraded minor -> patch for the maintenance line, matching Backport #3554: [core] Pin draw order to event-log order: retire delivery barriers through one ordered dispenser #3629.
Verification
Not run locally: the e2e lanes (they need a built workbench) and the Event Log Race Repro lane, which is the measurement that matters for this change. CI on this PR is the check.

Converting to draft so we can confirm that it doesn't cause regression in main beta branch before we re confident about rolling this backport over to stable

Manual backport of #3700 (cherry-pick 9b1b8c71) to stable. The automated job could not do it: every Backport to stable run since 2026-08-21 18:31 fails because the AI Gateway key is over its budget (API key budget exceeded. Current spend: $10001.21, limit: $10000.00), including the forced workflow_dispatch run, which resolved the SHA and cherry-picked correctly before dying at conflict resolution.
Stacked on #3718 (backport of #3406), which this commit cannot terminate without. Merge that first; this PR's diff is against it.
Why the prerequisite
#3700's turnstile waits on any lower armed barrier, a wider relation than gatesOn, and its deadlock-freedom argument rests on #3406 having removed computeResolvesOnItsOwn's unconditional step -> true shortcut. Cherry-picked onto plain stable, this commit's own turnstile termination pin fails with Unconsumed event: step_created: the step spinner is reported self-resolving, so hasParkedCommittedDelivery blocks the dispenser and the parked chain never opens.
Adaptations
  • workflow.ts: stable has no generateUlid const and installs the raw ulid factory as the STABLE_ULID global (upstream installs the counting generateUlid). Wrapped as countingUlid(seedTime?), preserving the factory signature, so mintCount counts every draw from the run's sequence including serialization-driven stream ids (the termination argument for quiesceEarlierCascades depends on that) without changing which seed time stream ids get on stable.
  • private.ts: the gatesOn doc hunk carries over via [core] Keep step results ordered behind waits parked on unread hook payloads (#3406) (backport to stable) #3718. isLogOrderDrawsEnabled, quiescenceTurn, quiesceEarlierCascades and awaitEarlierDeliveries are byte-identical to main.
  • test-support/orchestrator-context.ts does not exist on stable (that extraction is main-only) and is dropped. The mintCount wiring it carries applies to the local setupWorkflowContext copies in the four test files the commit already touches, which is where the cherry-pick put it.
  • docs/content/docs/v5/configuration/runtime-tuning.mdx does not exist on stable, whose docs tree has no v5/configuration directory. Dropped, matching Backport #3554: [core] Pin draw order to event-log order: retire delivery barriers through one ordered dispenser #3629 which carried no docs files for the same reason. WORKFLOW_LOG_ORDER_DRAWS stays documented on main.
  • .gitignore: took only this commit's addition (the e2e-diagnostics-*.json sidecar entry, whose writer does exist on stable), not the main-only event-log-race-repro-* block the conflict dragged in.
  • Changeset downgraded minor -> patch for the maintenance line, matching Backport #3554: [core] Pin draw order to event-log order: retire delivery barriers through one ordered dispenser #3629.
Verification
Not run locally: the e2e lanes (they need a built workbench) and the Event Log Race Repro lane, which is the measurement that matters for this change. CI on this PR is the check.
