#!/usr/bin/env bash
# raw-claude-enqueue.sh — PIGGYBACK enqueue into a LIVE Claude Code session's
# per-session mailbox (addressed by sessionId). Writes the message only; the
# session's Stop hook (cc-mailbox-rewake.sh) PULLS it at the NEXT turn boundary.
# For ACTIVE idle-wake (poke the watched signal too), use cc-enqueue-addressed.sh.
#
# COST: FREE. Just writes a file. (Claude Code has NO local external-push API; its
#       --remote-control is cloud-bridged through Anthropic, a different path.)
# LIVE SSOT: ~/.claude/sessions/<pid>.json with matching sessionId + status
#            (idle|busy), kind=interactive. NOT db/wal files.
# ENV: CC_MAILBOX_ROOT (default ~/.claude/mailbox).
# USAGE: raw-claude-enqueue.sh <session_id> <message...>
