feat(core): add explicit terminal-success exits - #39
Conversation
Capture the issue #38 contract before implementation so the new opt-in behavior, the scheduler barrier, and unchanged failure semantics are proven independently.
Scheduled workflows need an explicit no-op outcome that does not turn genuine failures into success. Add opt-in terminalSuccessExitCodes, scheduler-barrier handling, distinct completed_early reporting, and skipped remaining steps while preserving existing exit-code semantics.
Explain the explicit opt-in surface, completed_early reporting, scheduler barrier, and the additive status compatibility impact for published-package consumers.
📝 WalkthroughWalkthroughThis change adds opt-in terminal-success exit codes for deterministic steps. Matching exits produce ChangesTerminal-success workflow completion
Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🟡 Moderate · up to The new terminal-success behavior can still misclassify runs or skip work when execution is injected or a failed run is resumed, so the PR is not merge-ready until those state-handling paths are corrected; the duplicated validation logic is a bounded follow-up concern.

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.

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.

🎯 Functional Correctness | 🟠 Major | ⚡ Quick win
Handle terminal-success state consistently across alternate execution paths.
- In the injected
deps.executeSteppath, a deterministic step returning a configured terminal exit such as{ exitCode: 78 }is forwarded without derivingcompleted_early_exit, soexecuteAllcan schedule ready sibling steps. - When resuming a failed run, stale
completed_early_exitstate can survive a successful retry, causing the run to reportcompleted_earlywhile pending steps remain skipped.
Normalize terminal classification after either execution path returns, and clear or scope early-exit state when a resume attempt retries the failed step. Preserve verification failures and add regressions for both paths.

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 to end a run early when there’s no work. Before: any non‑zero exit failed the run. Now: a listed exit completes the step with reason completed_early_exit, skips all not‑started steps, and finishes the run as completed_early; verification and unlisted exits still fail.
Written for commit 5324a67. Summary will update on new commits.
