Summary

Fourth PR of the activity feed polish program (depends on A3, synoet/activity-feed-virtualized-6fe8; this branch includes A3's commits until it merges).

  • core/collapse-runs.ts: FeedEntry = single | run. Consecutive same-actor, same-entity, same-action events (and, for property changes, same property) fold into one run. A property run reads the net change (from of the oldest → to of the newest). Runs never cross a day header (groupEventsByDay buckets first, then collapses).
  • core/fold-panel.ts: foldPanel(entries, 3) → three newest, hidden count, oldest fetched entry pinned last. Nothing folds when everything fits.
  • core/feed-rows.ts: entry rows carry rail: { above, below } so the connector joins entries within a day and stops at day headers; reuseRows treats a changed rail as a new row.
  • components/activity-timeline-row.tsx, restyled after the reference picture: a plain action glyph (no disc or ring) on a thin connector that leaves a gap around each glyph; one line per row, never wraps; the entity name truncates first (to its icon in the tightest pane), then the sentence clips, and the actor, count and time always stay; compact relative time (17h, 8d, 1mo) after a middot, full date on hover; compact density for the panel; data-activity-run-size.
  • Side panel Activity renders the shared row; the bespoke ActivityRow, COLLAPSED_ROW_LIMIT, and Show all (n) are deleted. Folded state: three rows, a View all activities row in the rail (dotted connector, caret glyph), and the creation row; expanded shows all with Show less.
  • formatCompactRelativeTimestamp moves from the inbox utils to @entity/utils/timestamp and is shared.
  • ReadActivity tool wraps each event as a single entry (no collapsing in the tool).
  • Agent guides updated (surfaces.md, documents.md).

Demo

Before (main) then after (this PR). One document seeded with a create, five renames, two Launch phase changes, a rename, another Launch phase change, and two more renames (12 events). main lists them as separate rows; this branch shows six rows (5 times, 2 changes, 2 times) in the reference style, and the side panel folds to three rows plus the pinned creation row behind View all activities; the toggle is clicked to expand (Show less) and clicked again to fold.

Verification

  • bunx tsc --noEmit on apps/web, biome, bunx vitest run src/features/activity src/features/entity/utils/timestamp.test.ts — all green (129 tests). Includes the collapseRuns on 1,000 events < 2ms perf rule, measured as the fastest of 20 samples so a noisy CI runner cannot fail it.
  • Live stack (bash .cursor/stack.sh), Playwright against the running app: side panel folded/expanded, feed at 1280 and 720 (rows stay 40px, the long Quarterly Infrastructure Reliability Review… name truncates with the time still in view), as in the demo above.

Note: the Automation rows come from the seed scenario's system actions; A5 (synoet/activity-actor-attribution-6fe8) renames those and is independent of this branch.

📝 Summary

Summary by CodeRabbit

  • New Features
    • Activity feeds now group consecutive actions into concise entries with counts and net changes.
    • Activity history uses a virtualized, scroll-driven timeline that loads more entries automatically.
    • Entity activity panels support folded timelines with expandable details and pinned oldest entries.
    • Added loading skeletons for activity overviews and improved loading/error states.
    • “Most active” entities now appear as compact chips.
  • Documentation
    • Updated activity and side-panel guidance to reflect grouped timelines, chips, and automatic loading.

Walkthrough

The activity feature now collapses consecutive events into typed feed entries and grouped day rows. The activity view uses reusable virtualized rows and loads additional pages during scrolling. Timeline panels fold entries and pin the oldest entry. The overview supports skeleton loading, unavailable states, and top-entity chips. Tests cover grouping, folding, virtualization, loading, and rendering. Documentation describes the updated activity behavior.

Merge Risk: 🟡 Moderate · up to 56d50

Activity history can currently combine events from different days into one misleading row, and keyboard users cannot open the new entity chips. The date-boundary issue should be fixed before merge.

Make the clickable chip keyboard operable.

rowProps carries the host's click-to-open handlers, so this chip is interactive. The element is a plain div with no role, no tabindex, and no key handler. Keyboard and screen-reader users cannot activate it. The cursor-default class also hides the affordance from pointer users.

Rendering the chip as a button when rowProps is present, or adding role="button", tabindex="0", and an Enter/Space handler, resolves both points.

Use match(...).exhaustive() for rowKey.

The apps/web guidance requires ts-pattern for exhaustive matching. A plain switch can fall through when a new FeedRow.kind is added, causing reuseRows to use undefined as a map key. Rewrite this logic with match(row).exhaustive().

Consecutive same-actor, same-entity, same-action events (and same-property
changes) within a day fold into one FeedEntry run that reads with a count
and, for properties, the net from -> to. Both the feed and the side panel
render the one glyph-rail timeline row, now with the relative time inline
after a middot; the panel's bespoke ActivityRow and its Show all toggle are
gone. The panel folds past four entries to the three newest, a View all
activities row in the rail, and the oldest fetched entry pinned last.
