observability

Acceptance Criteria

  • Activity shows completed-or-duration on top with seconds
  • Action rows show created-to-completed span OK floated right
  • Timestamps persist at second precision

Expected Test Plan

  • [unit] duration and timestamp format helpers
  • [integration] activity and action rows render timestamps

Checks Run

  • [unit] heartbeat_helper_test.rb: time_seconds/clock/elapsed/action_span/completed_at formatters green
  • [component] heartbeat_event_table_test.rb: activity card (completed/created/timer/spinner) + action span render green
  • [integration] alex_heartbeat_test.rb: /alex/heartbeat renders second-precision timestamps + DB round-trip preserves seconds
  • [e2e] npx playwright test e2e/alex_heartbeat.spec.js — 8 passed (activity card timestamps, live timer, action span)
  • [full-suite@0433675be332d862ec26b9c10e755fe99583c003] bin/rails db:test:prepare test test:system green
  • [rubocop@0433675be332d862ec26b9c10e755fe99583c003] bin/rubocop clean

Agent Context

Observability UI: track + render started_at/completed_at at SECOND precision for activities AND actions, to see parallelism + finish times. ACTIVITY card (top to bottom): TOP = a live ticking-up elapsed timer from created_at while OPEN, replaced by completed_at (same datetime+seconds format) once closed; the [open]/[done]/stage-change badge floats right. MIDDLE = created_at (datetime + seconds) with the X-actions count on the right (spinner if open). BOTTOM = the task slug. ACTION rows: move the OK/status badge to FLOAT RIGHT of the action, and use the freed top line for the timestamp SPAN in EXACTLY this format: 'created at Jul 6, 19:24:11 - completed at 19:28:22' (full date+HH:MM:SS on start, HH:MM:SS on end). Data: ensure AgentActivity + AgentAction persist created/completed at second precision (add precision/columns + migration if missing). Files: app/views/heartbeat/* (activity + action rendering), app/models/agent_activity.rb + agent_action.rb + helpers. Do NOT build the triple-stack avatar (separate wave-2 task) but leave the agents-column structure clean for it. Verify live on /alex/heartbeat or /agents/activities.

Stage Timeline

Who handled each stage, the time it took (measured), and the model / tokens / cost reported (best-effort) — plus who's on it right now. — means the agent didn't report that metric.

Handoff avi 1 day ago

Reviewed: implements the specified layout (elapsed timer / completed_at second-precision, created at…-completed at… action span, OK floated right); no migration (columns already timestamp(6), completed derived); ui+db all four tiers green (unit/component/integration/e2e), full suite 3004/0, CI green, cert binds at head. Also fixed a pre-existing-red alex_heartbeat e2e spec. Approving; operator will eyeball the visual at QA before ship.
