When a gate exits with a listed code such as 78 but declares verification: { type: 'exit_code', value: '0' }, runVerification() still passes because verification.ts:226-229 implements checkExitCode() as an unconditional success, after which this branch assigns completed_early_exit. The native subprocess branch at lines 4805-4814 behaves identically, so the run incorrectly skips all remaining work despite failing its explicit verification; compare the observed exit code before classifying the exit as terminal success.

There was a problem hiding this comment.
When consumers use the exported StepExecutor with processSpawner, a deterministic step with a listed terminal exit is completed here without invoking verificationRunner at all. Thus an output_contains, file_exists, or custom verification that should fail cannot prevent executeAll() from marking the run complete early and skipping every pending step; run the configured verification before returning completed_early_exit.

Correction — my previous comment was wrong. This is NOT ready to merge.I answered "no in both directions" above. That answer was incomplete and, on one path, flatly wrong. The bot reviewers caught what I missed. Retracting and restating. The defect is real: a step CAN report terminal success while failing its artifact contractThree distinct paths, in severity order. 1. export function checkExitCode(_expectedExitCode: string): boolean {
// Existing runner semantics treat process success as established before this
// verification hook runs, so this check is currently an unconditional pass.
return true;
}That stub is only safe because of the invariant stated in its own comment: process success is already established before verification runs. In my earlier comment I claimed this combination "fails, which is arguably the correct outcome." That was wrong — I reasoned from the 2. The 3. The injected What this meansThe test I added ( What has to happen before merge
Method noteChief predicted this shape exactly — "a clean merge can combine two correct sides into a defect." The prediction was right; my verification was too shallow to find it. I checked one code path, found the guarantee held there, and reported it as a property of the system. Three green suites (961/961) did not catch it either, because no test covers the other two paths. Logging that here because "the tests pass" was doing more work in my earlier comment than it had earned. Still not merging. This needs the fixes above first. |

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
A resumed run can still report completed_early after all work finishes.
The detection at lines 4232-4234 keys only on completionReason === 'completed_early_exit', and the terminal step keeps that reason on its row. The resume reset at lines 4068-4073 clears the reason only on skipped siblings, not on the terminal step.
Reachable sequence with errorHandling.strategy: continue:
- A step fails and the terminal gate completes early in the same run, so
hasFailedStepis true and the run endsfailed. resume()accepts the run because its status isfailed.- The reset returns the skipped siblings to
pending, the retry succeeds, and every step then completes. completedEarlyStepstill matches, so the run is reportedcompleted_earlywithCOMPLETED EARLYin the summary even though no work was skipped.
Consider deriving the status from the current step states instead of the stored reason, for example by requiring at least one step whose status is skipped.

completionReason 'completed_early_exit' is stored on the terminal step and outlives the run it described. On resume the reset returns failed steps to pending; when they succeed, nothing is left skipped, yet the run still reported completed_early with '0 not-started steps were skipped'. Derive the claim from the current step states instead: no skipped step means no work was cut short. Found by coderabbitai on #39. Their conclusion was right; the mechanism they described (the reset returning skipped siblings to pending) was not - the reset only touches failed steps. The reachable path needs the failure and the gate in different scheduling waves, since a ready terminal gate is a barrier that runs alone. The regression test builds exactly that shape.

Summary
terminalSuccessExitCodesto deterministic YAML steps, custom deterministic steps, and the TypeScript buildercompleted_earlyrun status andrun:completed-earlyrunner eventskippedDesign rationale is recorded on issue #38: #38 (comment)
Semantics
If
claim-workexits 78 and verification passes, the step completes withcompletionReason: completed_early_exit, every pending step becomesskipped, and the run finishes ascompleted_early. The CLI exits 0 but labels the result COMPLETED EARLY, so operators can distinguish did-work, no-op, and failed runs.A terminal-capable gate runs alone before other ready steps. This prevents a no-op or lost-claim decision from racing work in the same scheduler wave.
Compatibility / what could break
Relayflows is already published at 1.0.7, so this does not reinterpret any existing exit code. Workflows without
terminalSuccessExitCodesretain their current behavior, including exit 78 failing by default.The changes that opt-in consumers and integrations must account for are:
WorkflowRunStatushas a new terminal value,completed_early; exhaustive switches, strict validators, database enum/check constraints, dashboards, and terminal-status pollers must handle it separately fromcompletedrun:completed-earlyterminalSuccessExitCodesbecomes a scheduler barrier, so other ready work waits for it even when it exits normallycompleted_early, while preserving the distinct status and labelTest-first proof
Commit
1be2aa5added the regression before the implementation. On that commit, this command failed as expected:The pre-fix runner returned
failedinstead ofcompleted_early, and a ready sibling started. The same regression now passes.Negative coverage proves failure handling was not weakened:
Validation
run-scriptandidle-nudgesuites: 39/39 tests passednpm run buildnpm run typecheckgit diff --check origin/main...HEADThe repository-wide concurrent test command was also attempted. It did not complete green because unrelated integration suites repeatedly exceeded their existing 15/30-second wall-clock test limits under concurrent mocked-process load; the failures were timeouts rather than assertion regressions. The affected suites and isolated timeout cases above are green.
Closes #38
Summary by cubic
Adds opt-in terminal-success exits for deterministic steps so a run can end early with a distinct completed_early status instead of failing. Also fixes exit-code verification to use the recorded process exit on every path and ensures a resumed run that completes all steps no longer reports completed_early.
