"""
response-harvester.py — Fleet agent readback and response harvesting daemon.

Monitors Chromebox agents (muse, pip, 646, opm), harvests incoming messages from
Main Chat and registered sidechats, maintains persistent watermarks, appends to
chat-history.jsonl, resolves pending follow-ups (verb-aware: [ACK|CLAIM] ->
acknowledged, [RESULT|DECLINE|NO-ACTION] -> resolved, outcome recorded), and
records [RESULT] completions in job-log.jsonl.

Features:
- Direct CDP over host veth interfaces (fast, no sudo needed).
- cdp_queue integration with PRIORITY_LOW (never blocks operator/DMs).
- URL state preservation (restores browser to initial thread/main via Ctrl+J).
- Bounded scroll-back for virtualized DOM (#hatch-chat-scroll).
- Per-node fault isolation (CDP errors on one node do not abort the cycle).
- Dual-mode execution (--once for systemd timers/CLI, --loop for daemon).

Usage:
    python3 response-harvester.py --once
    python3 response-harvester.py --loop --interval 30
    python3 response-harvester.py --agent 646 --once
