fix(core): make workflow runs durable across resumes - #23
Conversation
📝 WalkthroughWalkthroughWorkflow execution now persists runs to JSONL storage, accepts explicit resume IDs, and requeues stale running steps. Agent configuration now enforces exclusive CLI or persona modes. CI builds, tests, and type-checks the project. ChangesWorkflow resume and persistence
Agent configuration and validation
Estimated code review effort: 3 (Moderate) | ~25 minutes Merge Risk: 🟠 High · up to This PR makes workflow runs resumable, but cache-only resume can bypass configured permission profiles and grant readwrite access, creating a concrete security risk; the CI workflow also leaves checkout credentials available to pull-request-controlled commands. Merge should wait for these issues to be fixed or explicitly accepted by the responsible owners. Sequence Diagram(s)sequenceDiagram

There was a problem hiding this comment.
When another process calls --resume while the original runner is still alive, resume() accepts the run because its status is running, and this branch unconditionally changes every active step to pending. The resumed scheduler then executes those steps again while the original process may still be executing them, duplicating non-idempotent commands or agent side effects and racing JSONL updates. Only requeue a running step after confirming that its owning runner is no longer active, or reject resumes of actively leased runs.

This is a live P0, and I have the end-to-end evidence. It has been open for a month.Reviving this rather than opening a competing PR — I wrote the same fix an hour ago before finding this, and threw it away. Proof this is real, from a run todayI ran Native's Autopilot tick ( Then looked for the run record: A successful run persisted nothing. The chain is exactly what this PR fixes:
So every run through the published binary is memory-only, and No warning fires either, because the one that exists lives in Why it went unnoticed for a month964 unit tests, typecheck clean, and four green CI runs all pass with this bug present. It is only reachable when the real binary wires the real runner against a real workflow. This is the strongest single argument for the end-to-end gate we are now building. Three refinements from the version I discardedOffered as review, not as a competing PR — take or leave:
Blocking question before merge
Merge order I am tracking: #42 → #23 → #44 → #39, with #43 independent. Not merging anything myself. |
Persist runWorkflow state to the JSONL database, expose builder resume options, and retry stale running steps after interruption. Session-Id: 568eca24-d8dd-4afd-810d-3d804a51d100
The initial commit dropped the third argument from builder.ts's two runner.resume() calls. That argument feeds reconstructRunFromCache(runId, config), the cached-step-output fallback used when workflow-runs.jsonl is absent -- exactly what resume-fallback.test.ts covers. Restore it. run-persistence.test.ts also could not fail: its fixture used 'steps: []', which validateWorkflow rejects, so parseYamlFile threw before any assertion ran. Give it a real deterministic step, and strengthen the builder-resume assertion to require the config argument so this regression cannot recur. Session-Id: 568eca24-d8dd-4afd-810d-3d804a51d100
- run.ts: pass the parsed config to resume(). Without it, cache-only resume fails when workflow-runs.jsonl is unavailable, because resume() needs the config for reconstructRunFromCache(). This bug predates the PR; builder.ts was already passing it. - runner.ts: clear retryCount when resetting a step, so a step that succeeds on its first resumed attempt no longer reports stale retries. - runner.ts: gate the running-step reset behind ResumeOptions.resetRunningSteps (default false). Runs carry no lease or heartbeat, so a live owner cannot be detected; unconditionally requeueing running steps let a second resume re-execute them alongside the original process and duplicate non-idempotent side effects. The user-facing resume paths (run.ts, builder.ts) opt in, because --resume explicitly means the previous process is gone. A real ownership lease is the proper fix and is out of scope here.

actions/checkout v4 persist-credentials default true README GitHub
💡 Result:
In the actions/checkout action, the persist-credentials input defaults to true [1][2]. This setting configures the authentication token (or SSH key) into the local git configuration, which allows your workflow scripts to run authenticated git commands (such as git push or git fetch) [3][4][5]. The token or SSH key is automatically removed during the post-job cleanup phase [3][4]. If you do not want these credentials to be persisted in the local git configuration, you can explicitly set persist-credentials to false [3][4]. Note that in more recent versions of the action (such as v6.0.0), the implementation of this persistence has been updated to store credentials in a file under $RUNNER_TEMP rather than directly in the.git/config file, improving security while maintaining the same default behavior [5][6].

Disable checkout credential persistence. actions/checkout@v4 stores GITHUB_TOKEN in the local Git configuration by default. The workflow then runs pull-request-controlled npm commands, which can read or forward the token. Set persist-credentials: false and provide separate credentials only when a later step requires authenticated Git access.

Summary
Fixes three workflow-resume durability defects. Each was found by running the code, not reading it.
packages/core/src/run.ts—runWorkflow()constructedWorkflowRunnerwithout adb, soit fell back to
InMemoryWorkflowDb(runner.ts:703). Run state died with the process, and--resume— accepted atrun.ts:27, dispatched atrun.ts:86— could never succeed. It nowbuilds the cwd-backed
.agent-relay/workflow-runs.jsonlDB, matchingbuilder.ts:523.packages/core/src/builder.ts—WorkflowRunOptionshadstartFrom/previousRunIdbut noresume. The entrypoint that did persist state had no way to resume it, while the entrypointthat accepted
resumehad no persistence. Addsresumeand dispatches torunner.resume(...).packages/core/src/runner.ts—resume()reset onlyfailedsteps topending. A steppersisted as
runningwhen the process was killed stayedrunningforever and the run failed.A step cannot legitimately be
runningwhen no process owns it, so stalerunningis now resettoo.
Evidence
Reproduction, using a three-step deterministic workflow (no agents, so this isolates durability
from agent behaviour),
kill -9during step two:--resume <id>Run "…" not found (no database entry or cached step outputs)3 passed, 0 failedThe "after" column was verified against a locally patched build reproducing these three changes
before this branch existed; the branch itself is verified by the test results below.
Validation
Run on macOS 26.3.1 / Node 25.8.1.
npmhangs at 0% CPU on this machine, so the underlyingbinaries were invoked directly via
bunx. Worth noting for CI: the root scripts chain everythingthrough
npm run --workspace=…, so on any host where npm misbehaves the entire verification pathyields no signal at all.
bunx tsc --noEmit(packages/core) — clean, exit 0bunx tscfor github/slack/browser primitives — all exit 0bunx vitest run run-persistence.test.ts resume-fallback.test.ts— 10 passed / 10Pre-existing failures (not caused by this PR)
9 of those 10 are in
run-script.test.ts(TypeScript strip-types preflight, plus a 30s timeout).Baselined on
mainatb086a87: the same 9 fail there (9 failed | 17 passed). This PRneither causes nor fixes them.
The 10th was a defect in this PR's own first commit, fixed in
e2a2e73— see below.Note on the second commit
The first commit dropped the third argument from both
runner.resume()calls inbuilder.ts. Thatargument feeds
reconstructRunFromCache(runId, config), the cached-step-output fallback used whenworkflow-runs.jsonlis missing — precisely whatresume-fallback.test.tsexists to cover. Thetwo call sites were "harmonised" toward the broken one.
run-persistence.test.tsalso could not fail: its fixture usedsteps: [], whichvalidateWorkflow(runner.ts:3192) rejects, soparseYamlFilethrew before any assertion ran.e2a2e73restores the argument, gives the fixture a real step, and strengthens the assertion torequire the config argument so the regression cannot recur silently.
