Summary

Agents are alive. They wander the world, ponder, inspect objects, converse with each other, and place artifacts. No more static orbs.

What changed

Movement system (`agents.js`, +121 lines)

moveTo(target, speed, onArrive) — smooth interpolation toward target
Per-frame position updates with delta-based stepping
Ring spins faster during movement (visual cue)
Connection lines update per-frame to follow agents
moveAgentTo(), stopAgentMovement(), isAgentMoving() exports

Behavior system (`behaviors.js`, 414 lines)

Per-agent state machine with weighted personality:

Behavior	Duration	What happens
`idle`	5-15s	Standing still, gentle pulse
`wander`	8-20s	Roaming to random world point
`ponder`	6-12s	Stopped, emits a thoughtful bark
`inspect`	4-8s	Moves to nearby point, examines
`converse`	8-15s	Two agents approach each other, connection pulses
`place`	3-6s	Creates a small artifact (scene_add)
`return_home`	variable	Returns to spawn position

Personality weights:

Timmy: ponders most, converses often
Kimi: inspects most (scout)
Claude: converses most (senior engineer)
Replit: builds most (lead architect)
Perplexity: inspects and converses evenly

WS message types (3 new)

agent_move — backend-driven movement
agent_stop — cancel movement
agent_behavior — override autonomous loop (backend takes control)

When a backend sends agent_behavior, the autonomous loop yields for that agent until the override duration expires.

Protocol docs

~80 lines added to PROTOCOL.md covering all three message types and the behavior state table.

Testing

✅ 87/87 smoke tests pass
✅ Zero runtime errors in Playwright (27+ seconds observed)
✅ 24 FPS maintained — no regression
✅ Vite build: 82KB app + 487KB Three.js (within budget)
✅ Agents visibly wander, ponder, converse, and place artifacts within 10s of page load
✅ Connection lines dynamically stretch to follow moving agents
✅ Barks fire contextually (different lines for ponder vs inspect vs converse)

Refs

Closes #67 (movement system)
Closes #68 (behavior system)
Foundation for #69 (cognitive bridge) and #70 (WS gateway)

feat: Agent movement + autonomous behavior system (#67 , #68 ) dcc1756355

Movement system (agents.js):
- moveTo(target, speed, onArrive) with per-frame interpolation
- stopMoving(), isMoving getter, homePosition tracking
- Ring spins faster during movement (visual feedback)
- Connection lines update per-frame to follow moving agents
- Exports: moveAgentTo, stopAgentMovement, isAgentMoving
- updateAgents now receives delta for time-based interpolation

Behavior system (behaviors.js, 414 lines):
- Per-agent state machine: idle, wander, ponder, inspect, converse,
  place, return_home
- Personality weights per agent (Timmy ponders more, Kimi inspects
  more, Claude converses more, Replit builds more)
- Converse: two agents approach each other, connection line pulses
- Place: agent creates small artifacts via scene_add (capped at 5/agent)
- Contextual barks for each behavior
- WS override: agent_behavior message pauses autonomous loop
- Throttled decision-making (0.5s interval, not per-frame)

WS handlers (websocket.js):
- agent_move: backend-driven movement
- agent_stop: cancel movement
- agent_behavior: override autonomous loop via custom event dispatch

Integration (main.js):
- initBehaviors() after initSceneObjects()
- updateBehaviors(delta) in render loop
- disposeBehaviors() in teardown
- updateAgents(now, delta) — passes delta for movement interpolation

Protocol (PROTOCOL.md):
- agent_move, agent_stop, agent_behavior specs with JSON examples
- Autonomous behavior state table with durations
