Adds an audit trail per board, visible from a new clock-icon button on the
toolbar. Useful for review-style work where someone wants to see who
contributed which references and when.
Logged events (high-signal only — canvas-edit noise intentionally skipped):
- image / video / pdf added (whether dropped, pasted, or pulled from a URL)
- board created / renamed / deleted
- thread started, resolved, reopened
- comment posted on a thread
Backend:
- new activity_logs table (id, board_id, user_id, denormalised actor name +
email, action, target_type/id/label, metadata JSON, created_at) with an
index on (board_id, created_at DESC).
- logActivity helper resolves the user once at log time and stores their
display name + email so entries survive deactivation/rename.
- recordActivity wraps logActivity + a Socket.IO emit to the board's room
so the panel updates live without polling.
- GET /api/boards/:id/activity?limit=&before= for pagination
(collection-membership gated, viewer+).
Frontend:
- ActivityPanel side-drawer: time-grouped feed (Today / Yesterday / older),
per-action icons + tone colours (add/remove/edit/comment), pagination
via "Load older", live append on Socket.IO 'activity:new'.
- Relative timestamps refresh every 30s.
- Wired into Editor + Toolbar.
README updated; roadmap entry checked off.
