ChangesInitial sync resume flow
Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🟡 Moderate · up to The retry change can exceed the configured startup deadline and may leave detached sync work or mount activity running after a status failure. This can cause late daemon readiness or lingering sandbox work, so the PR is not merge-ready until the timeout and cleanup paths are explicitly contained.

Full details: Linked Issues checkExplanation The PR implements resumable handling for incomplete initial syncs, but the provided change summary does not show the remaining initial-sync launch and daemon-start execs being wrapped with named mount-phase classifications or the hanging operation and cause being identified as required by issue Full details: Out of Scope Changes checkExplanation The implementation and tests focus on resumable initial sync handling, bounded polling, and preventing daemon startup before a clean exit 0. These changes are related to the pull request objectives and issue Full details: Docstring CoverageExplanation No functions found in the changed files to evaluate docstring coverage. Skipping docstring coverage check. Docstring coverage is scoped to functions touched by this diff. Analyzed 0 functions across 2 files. ✨ Finishing Touches📝 Generate docstrings

In `@src/orchestrator.ts`:
- Line 261: Update launchInitialSync and its runtime.runScript flow to enforce
the remaining deadline for every initial-sync attempt: reject before relaunching
when no budget remains, pass the remaining budget so the adapter can cancel a
stalled request, and check deadline before accepting a successful status-probe
result so late exit code 0 responses fail instead of starting the daemon.
Apply the same fix in `@src/orchestrator.ts` at line 324: Covers the late-success
completion path described by the original comment.

Closes #45.
Relayfile exit 75 is TEMPFAIL: the same sandbox owns a resumable traversal checkpoint.
startMountnow relaunches the detached initial sync against that checkpoint instead of treating incomplete readiness as fatal. All attempts share the existing bounded wall-clock deadline; the daemon still starts only after a clean exit 0.Validation:
node --test --import tsx src/orchestrator.start-mount.test.ts— 12 passednpm test— 820 passed, 9 skipped, 0 failednpm run build— passedgit diff --check— passedLive Daytona proof remains a merge/release gate: publish the package, bump Cloud, deploy, and rerun the self-contained Relayfile review Gist on the populated production workspace.
Summary by cubic
Closes #45.
Fixes incomplete initial syncs so
startMountresumes them instead of failing on TEMPFAIL exit 75. The detached sync now relaunches against the persisted checkpoint, and the daemon still starts only after a clean exit 0.Written for commit 626c8db. Summary will update on new commits.
