Finished Active Agents rows were truthful but ambiguous: users read them as complete even when a dirty worktree still needed cleanup. Keep the underlying activityKind stable, but present that state as Needs cleanup in the sidebar, summaries, tooltips, and session descriptions. Split these rows out of Idle / thinking so the remaining worktree has an obvious cleanup reason.

Constraint: activityKind remains finished for compatibility with existing state derivation

Constraint: Active Agents template must stay byte-for-byte synced with the canonical extension source

Rejected: Hide finished dirty worktrees | hiding would make leftover files less visible and harder to clean

Confidence: high

Scope-risk: narrow

Directive: Do not reintroduce Finished as user-facing wording for dirty idle worktrees without explaining cleanup state
