# Preferred install path: `npx auxilo setup` GENERATES a copy of this hook at
# ~/.auxilo/bin/auxilo-extract.sh with absolute paths embedded (lib/installer.js
# renderHookScript). This template is the $HOME-relative fallback used by the
# legacy `scripts/runner.js --install-hooks` copy step.
#
# Reads the Claude Code SessionEnd JSON from stdin, extracts the transcript
# path, and spawns the extraction runner detached so shutdown is not blocked.
# Runner location per P1-13: executable surface lives in ~/.auxilo/bin —
# NEVER under ~/Documents (macOS TCC blocks launchd/hook execution there).
