✅ Duplication (TypeScript) — clean
New TypeScript code duplication introduced by this branch. Fails at 70+ tokens in app code, or 150+ tokens when both copies live in test files. Advisory while the gate proves itself: extract a shared helper instead of copying.
✅ Bundle size — no change
Uncompressed size of every built .js bundle, compared against the base branch.
Total: 68.38 MiB · no change
No file changed by more than 1000 B.

✅ Eager graph — within budget
How much code each root ships on the eager path — downloaded and parsed before the surface is interactive. Measured from the esbuild output chunks (post-tree-shake, static imports only); lazy import() / React.lazy chunks are not counted.

✅ Toolbar bundle — eager 2.36 MiB within budget
What the toolbar ships to customer pages, measured from the esbuild output (minified, post-tree-shake). The eager set is the entry plus everything statically imported from it — fetched before any feature runs; deferred chunks load lazily. The eager guardrail is 5.72 MiB. Each output file must also stay below 10 MB, where CloudFront stops compressing it. The module boundary is enforced separately by check-toolbar-graph.

- Please do not call
update_task_runwhile holding this row lock. Its post-write lifecycle includes push dispatch setup that evaluates a feature flag and Redis cooldown before registeringon_commitwork, so this nesting keeps those dependencies and other callbacks inside the outer transaction. A slow dependency can block the scheduled-run dispatcher and concurrent cancellation for the duration of the request, while a rollback can leave non-transactional effects out of sync; keep the lock/transition separate from post-commit side effects.

- This early return bypasses the
run.capture_event("task_run_cancel_requested", ...)block below, so canceling a dormant scheduled run emits no cancellation-request event while normal cancellations do. Record the cancellation event on this path as well, using an explicit outcome for the fact that no workflow signal was needed.

PR overviewThis pull request adds support for scheduling one-off task runs through the API and MCP, with a dispatcher that starts scheduled workflows. One issue remains after another was addressed. Scheduled non-exempt tasks do not revalidate cloud-code eligibility at execution time, so a run created while eligible may still start after the organization loses access. Exploitation depends on an entitlement change occurring between scheduling and execution. Open issues (1)

Addressed the remaining Copilot review points in f3d2b87. Scheduled cancellation now uses a conditional status update. Notification setup runs after the row lock ends. The existing cancellation event is retained. If dispatch starts first, cancellation uses the normal workflow signal. The task-list projection no longer requests a field absent from the summary DTO. The model-only resume schema was fixed in 00a6f35. Checks passed: 11 cancellation tests, 10 generated MCP tool tests, MCP type checking, full Python type checking, and CI preflight. |

Low: Missing cloud access revalidation
A user can schedule a run while entitled and have it execute after the organization becomes ineligible for cloud-code access, such as after moving onto a Startup program or prepaid credits. Immediate starts explicitly call the Desktop access gate, and the surrounding create-path comments establish that this entitlement must hold when execution begins; re-evaluate it here for non-exempt tasks before starting the workflow, alongside the usage check.
There was a problem hiding this comment.
I am the coding agent assisting with this PR.
This remains possible. I did not add a dispatch-time Desktop entitlement policy in this change. ReviewHog identified the same concern and confirmed that other deferred paths, including loops, do not repeat that entitlement check.
The focused fix repeats the existing usage gate for scheduled CREATE dispatches. It blocks deactivated organizations and reported usage limits before Temporal starts. Project membership remains checked. It does not claim to enforce Desktop entitlement at dispatch.
I left the wider entitlement decision open in the ReviewHog thread: #103087 (comment). That change needs an explicit policy for deferred runs, signal-report exemptions, and entitlement-resolution failures. I am leaving this thread open too, rather than marking the concern fixed.

the 90-day window is longer than the 30-day TTL _attach_staged_artifacts_to_run applies to pending_user_artifact_ids. a run scheduled for day 31+ can start after its input files have already been deleted, so can we either cap those schedules at the artifact lifetime or retain them through scheduled_at?

pending_dispatch commits with the run before _attach_staged_artifacts_to_run runs. if that attachment fails, the request errors but the materializer can still start a partially initialized run later, and a client retry can create duplicate work. can we keep it ineligible until attachment is complete, or roll the run back on failure?

scheduled dispatch needs to recheck task_control_q, not just team membership. if someone is removed from a private channel but stays on the team, a new /run/ is denied while this persisted run still starts with its GitHub/MCP credentials. could we fail the dispatch in that case and cover private-channel removal in a test?

can we run this gateway check off the thread-sensitive executor? usage_limit_response can block for 2.5s, and sync_to_async defaults to the single thread-sensitive worker, so 20 concurrent scheduled dispatches become roughly 50s of serial checks during a gateway outage.

can we detect an already-started create dispatch before rerunning this gate? temporal can accept start_workflow while the client times out, leaving the retry on a still-QUEUED run. if usage becomes limited before retry, this calls mark_dead and fails a run whose workflow is already running instead of reaching WorkflowAlreadyStartedError.

would it be worth pulling this run-source-to-MCP-scope mapping into one helper? it's now copied here, _trigger_task_processing_workflow, and _resolve_mcp_scopes, so a new run source can quietly give scheduled, immediate, and recovered runs different permissions.

id keep the object-storage calls outside this transaction. _attach_staged_artifacts_to_run makes one S3 tag request per attachment after task.create_run locks the task row, so a slow batch holds the database lock and successful tags survive a later rollback anyway. can we tag first, then atomically create the run and save its manifest?

Problem
Agents can start tasks through MCP, but cannot request a one-off run at a future time.
Why: Expose the scheduler from #102245 through the existing start tools, without a separate scheduling system.

Used the MCP, DRF, test, dataclass, user-facing copy, STE, PR description, and CI preflight skills. No matching open issue or duplicate PR found. Test data is synthetic. CodeRabbit CLI is absent, so no local CodeRabbit review ran. Human review and CI remain required.
Review fixes align generated request schemas and reject Desktop-imported credentials on scheduled runs. Scheduled dispatch rechecks task access and usage limits. Retries preserve workflows that already started.
