Follow-up to #2673 (merged as cf0292607), which made ticking a task off delete its Gmail draft.

That change raises a question nothing asserted: reopen a task whose draft was deleted , from the task list's Completed section, or by unticking it on the agenda , and what do you get?

The answer is the intended one, and these pin it:

deriveAgendaRightSlot already derives this correctly from the stripped taskActionData; the tests exist so a future change to the cleanup shape cannot quietly reintroduce the dangling affordance. The last case asserts through deriveAgendaActionButton that it resolves to { kind: 'execute' } and not a green "Open draft" pill pointing at a draft that no longer exists , the derivation keys off draftId alone, so leaving the pointer behind would have produced exactly that.

The chat-thread case is a deliberate split

Cleanup clears the draft pointer but does not touch chatThreadId. The chat thread is real history that still exists, and the user may want to return to it and ask for a redraft , deleting the draft should not silently delete the conversation that produced it. clearTaskOutput remains the path that forgets an output entirely, nulling both, and its docstring already says the slot then "collapses back to 'invoke'".

So: completion deletes the artifact; clearTaskOutput forgets the whole output.

Test plan

• pnpm run autofix:local green (exit 0 across oxlint --deny-warnings, deps:check, paraglide, Jest, and 11,106 Vitest tests).
• Tests only , no production code changes in this PR.

Note on the branch

fix/dm-container-kind was auto-deleted when #2673 merged; pushing this commit recreated it. The branch is exactly one commit ahead of staging. Happy to move it to a fresh branch name if the resurrection is confusing.

Greptile Summary

This test-only PR pins the agenda right-slot behavior for reopened tasks after their Gmail draft has been cleaned up:

• Shows Execute when no draft remains, whether or not an email thread remains.
• Preserves the bot affordance when chat history remains.
• Verifies the action button cannot resolve to Open draft without a draftId.

Confidence Score: 5/5

The PR appears safe to merge; it adds focused tests that match the current cleanup contract and agenda derivation behavior.

No actionable defects were found in the changed test coverage, and the cleanup shape is independently asserted by existing server-side tests.
