Task status and activity disclosure

CoWork projects task events into one renderer-owned model for the main timeline, right panel, replay, and the compact status strip above the composer. The model keeps user-facing plan steps, activity groups, individual tool activities, and outcome metrics separate so tool-call volume is never presented as plan progress.

Status strip

TaskStatusStrip shows the current step or task state plus at most two trusted metrics. Clicking it opens a bounded, non-modal overview of the plan, latest activity, impact, outputs, verification, and blocking state. Plan and output controls route to the existing timeline and artifact surfaces.

The local rollout flag is task-status-strip-enabled. It defaults to enabled and can be disabled by setting its localStorage value to false. When renderer performance logging is enabled, drawer open/close telemetry records categorical counters only. It never includes labels, paths, arguments, filenames, or task content.

Trusted impact metrics

The renderer formats the additive TaskImpactMetric contract in src/renderer/utils/task-impact-metrics.ts. It accepts persisted, attributed snapshots and a small set of typed timeline evidence. It never parses assistant prose or arbitrary tool-result text.

Current sources are:

• citations and evidence references for collected sources;
• artifact/output events for created artifacts;
• verification events for passed checks;
• agent lifecycle events for active-agent counts;
• explicit impactMetrics returned by canonical presentation and spreadsheet tools;
• the task mutation ledger for changed files and attributed text-line impact.

Unsupported metrics remain absent until a producer exposes an explicit typed count. Connector tools may add records_updated through the same canonical outcome contract once their success semantics and count are reliable.

Mutation attribution

Before a core file tool mutates a path, the daemon captures its first task-local baseline under the CoWork user-data directory. Successful file events recompute impact against those baselines and persist coalesced task_impact_updated snapshots. This includes CoWork's uncommitted writes while excluding changes that predated the task. Binary files contribute to files_changed but not line totals. If any relevant baseline is incomplete, the renderer receives the file count and omits line addition/removal metrics.

These snapshots are part of normal event persistence, replay, fork/resume, and remote transport; remote renderers do not inspect a local Git worktree.

Disclosure behavior

Disclosure state uses auto, expanded, and collapsed intents scoped by task and by group or activity ID. The current auto group opens; completed auto groups close. Explicit user intent wins, so a collapsed running group stays collapsed as new events arrive. The cache is bounded across task switches.

Large groups retain all lightweight summaries in a measured, virtualized viewport. Auto-follow runs only while the viewport is near the bottom; otherwise a new-activity control reports pending rows. Replay disables live auto-follow and transition motion.

Accessibility and motion

Expandable headers are semantic buttons with aria-expanded and aria-controls. Escape closes the status drawer and restores focus; collapsing a group or activity restores focus before removing a focused child. Live-region announcements are throttled and limited to plan-step, blocking, and completion transitions. Touch targets expand to at least 44 pixels for coarse pointers.

Disclosure and latest-label motion use the Web Animations API and transform/opacity/clip effects. Reduced-motion mode and replay apply state changes immediately. Forced-colors styles preserve boundaries and selected state without relying on color alone.

Validation

Focused coverage lives in the task status projection, impact metric, disclosure, status strip, mutation ledger, canonical tool outcome, timeline snapshot, and renderer performance tests. The performance fixture exercises 1,000 and 10,000 activity events, large hidden payloads, repeated disclosure changes, and bounded live transcript projection.
