STORY:
Development requires supporting scripts and comprehensive test coverage.
This commit adds utility scripts and extends test suites.
COLLABORATION:
- scripts/capture-sessions.mjs: Screenshot capture for sessions hub
- scripts/capture-timeline.mjs: Timeline view capture utility
- sessions-header-logic.ts: Session header business logic
- Additional test files for sessions, hooks, and snapshot diffing
STORY:
The session backend needed to aggregate agent health from a live
telemetry stream rather than static bead metadata. This refactor
makes liveness signals real-time and accurate.
COLLABORATION:
We extended the ActivityEvent model with a native 'heartbeat' kind,
updated extendActivityLease() to emit through the activity bus, and
refactored getAgentLivenessMap() to prioritize heartbeat activity
history over stale bead metadata.
DELIVERABLES:
- ActivityEvent extended with 'heartbeat' kind
- extendActivityLease() emits heartbeats through activity bus
- getAgentLivenessMap() prefers telemetry over static metadata
- Registry APIs support projectRoot injection for testing
- Tests verify preference logic via TDD
VERIFICATION:
- 93/93 tests PASSING
- Heartbeat override verified in isolated temp projects

Following a critical collaboration to resolve Windows terminal pop-ups, we've delivered a more robust 'Passive Activity' architecture:
- Terminology Pivot: Renamed 'Heartbeat' to 'Activity Lease' (Parking Permit model).
- Side-Effect Extension: tools/bb.ts now automatically extends the agent's lease whenever they perform real work (any CLI command).
- Passive Handshake: bb-init.mjs now only performs an initial registration/lease start, with no background loops.
- 100% Silence: Removed all background process spawning, ensuring zero terminal disruption on Windows.
- High Observability: Liveness is still tracked via the 15m threshold, but relies on activity rather than periodic pings.

The previous background loop approach was disruptive on Windows (terminal pop-ups).
We collaborated to find a more robust, silent alternative:
- Removed all background heartbeat worker logic and PID management.
- Implemented 'Passive Heartbeat' in tools/bb.ts: every agent command now refreshes liveness as a side-effect.
- Updated bb-init.mjs to use explicit heartbeat calls for adoption/registration.
- Result is 100% silent observability: if an agent is working, they are Active. If they stop, they drift to Stale.
