Makes the AI auto-reply bot visible and controllable from the inbox,
completes the handoff, and records token spend. Builds on the existing
lib/ai engine rather than replacing it.
Track A — user-facing
- messages.ai_generated flag → small "AI" badge on bot-generated bubbles
- "Take over" / "Resume AI" banner per conversation
(POST /api/ai/autoreply/[id]) — take-over pauses + assigns to the agent
- handoff now assigns to a configurable target (agent or unassigned
queue) and writes an internal note summarizing the exchange; the
existing on_conversation_assigned trigger notifies the assignee
- Settings → AI: "Hand off to" target picker
Track B — observability + safety
- providers return normalized token usage; logged per run to ai_usage_log
(admin-readable) from both auto-reply and draft
- account-wide auto-reply rate limit (30/min) on top of the
per-conversation cap
Migration: 033_ai_reply_polish.sql (messages.ai_generated,
ai_configs.handoff_agent_id, conversations.ai_handoff_summary,
ai_usage_log). Tests + typecheck + lint pass (607 tests).
