# Bash shim — Claude Code hooks run `command` strings via /bin/sh, so this
# wrapper makes the TypeScript hook executable via bun. Settings.json
# references this file directly (registered by bin/gstack-memorable enable,
# never by ./setup).
#
# FAIL-OPEN: a third-party recall bridge must never block a prompt. Every
# failure path — bun missing, script crash — still exits 0 with empty stdout.
#
# bun runs as a job, not a foreground child: bash holds a SIGTERM until a
# foreground child exits, so a host that terminates this shim would leave the
# vendor process running with the prompt on its stdin. Forwarded, the signal
# reaches the .ts, which kills the vendor's process group on its way out.
# `<&0` keeps stdin: bash hands background jobs /dev/null otherwise.
