- Around line 51-56: The README entry for waitForRunSnapshot incorrectly
documents a null return contract. Update it to state that the function returns
SettledRunSnapshot, with SettledRunSnapshot.content set to null when no artifact
is produced, and add SettledRunSnapshot and WaitForRunSnapshotOptions to the
exported-types row.
In `@packages/cloud/src/cloud-runs.ts`:
- Around line 517-546: The custom sleep path in waitForRunSnapshot must remain
abortable. Update the sleep invocation around the sleep helper and
options.signal to race caller-supplied sleep with the abort signal, while
preserving the existing default abortableSleep behavior. Add a regression test
covering a pending custom sleep and an already or subsequently aborted signal.

Addressed the outside-diff snapshot-test finding in 212f6ed as well. The no-op CLI test now reads the saved snapshot, asserts its exact serialized content, verifies fixed execution timestamps and preserved source blocks, and proves stale outputs/execution counts are removed. Full validation: 2,790 tests passed (1 skipped), typecheck, Biome, Prettier, and CSpell all passed. |

(agent observation) The docs say success only means "the notebook ran fine" and that a run with no snapshot exits 0. The code does neither: success is false whenever the snapshot isn't saved, and no-snapshot exits 1. Please update the docs to match the code. Also, the PR description's "breaking change to success" isn't right — main already worked this way; the real change is that snapshot errors moved from error to artifactError.
There was a problem hiding this comment.
Fixed in b386cc7: cli-run.md and the CLI README now document the actual contract — success is the overall command outcome (run succeeded AND its snapshot was delivered), and a successful run with no snapshot exits 1 with artifactStatus: not_produced and an artifactError, including the --notebook-id-only case. They also cover the new artifactStatus: synthesized value from the sibling thread. You are right about the PR description too — a corrected version (success keeps the meaning it had on main; the real change is artifact failures moving from error into artifactStatus/artifactError) is written and will land on the description shortly. Please resolve if satisfied.

(agent observation) When the API returns no snapshot for a markdown-only local notebook, the CLI now writes a snapshot it made up from the local file and reports it exactly like a real one (saved, exit 0). If the local file is out of date, or the API is just down (the test at :536 passes with every re-fetch returning 503), the user gets a wrong "no outputs" file and no warning. Please mark these differently (e.g. artifactStatus: 'synthesized') and say so in the terminal output.
A bit similar thing in cloud-runs.ts:562, run-in-cloud.ts:411 - if the API returns snapshot content that is an empty string, the CLI now writes an empty file and reports success. Before this PR that was an error. Treat empty content as "no snapshot yet".

Both fixed in 729053f: (1) synthesized no-op snapshots now report artifactStatus: "synthesized" instead of "saved" in -o json/-o toon, and human output prints an explicit note that an output-free snapshot was synthesized from the local source rather than produced by the run; (2) empty snapshot content is now treated as not-yet-attached inside waitForRunSnapshot — it keeps settling and returns null if the content stays empty, so the CLI reports not_produced and exits 1 instead of writing an empty file. Added tests for the synthesized status (JSON + human disclosure), empty-then-real content, and persistently-empty content. Please resolve if satisfied.
…ontent as absent A snapshot synthesized from the local source for a no-op run now reports artifactStatus: 'synthesized' (not 'saved') and human output says so, so machine consumers and users can tell it apart from an API-produced artifact. Empty snapshot content from the API is treated as not-yet-attached in waitForRunSnapshot instead of being written out as an empty file. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
…t synthesized status The docs claimed success described notebook execution alone and that a no-snapshot run exits 0 — the code fails the command (exit 1) whenever a successful run's snapshot is not delivered. Also documents the new artifactStatus: 'synthesized' value and empty-content handling. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

Leaving this finding, as it indicates potential logic error: "stale lastRetryError misclassifies a confirmed "no snapshot" as unavailable If an early status re-fetch fails transiently but a later one succeeds and shows no snapshot attached, the CLI throws the old error anyway and reports artifactStatus: 'unavailable' with an unrelated network message instead of not_produced."
There was a problem hiding this comment.
Confirmed — lastRetryError was never cleared, so an early transient re-fetch failure survived a later successful re-fetch that freshly confirmed no snapshot, and the CLI reported unavailable with the unrelated network message instead of not_produced. Fixed in #479: waitForRunSnapshot now clears the tracked failure on each successful status re-fetch and reports it as SettledRunSnapshot.retryError only when the last re-fetch failed (final observation stale); the CLI throws that instead of its own accumulated state. All-failed re-fetches still report unavailable. Regression tests cover both directions. Please resolve if satisfied.
Parent PRs #432 and #448 were squash-merged, so this branch carried duplicate history for their files.
