#!/usr/bin/env bash
# KeiSei pet state updater — called by hooks to change the pet's mood.
# Usage: keisei-pet-update.sh <event>
#   Events: prompt | rust_write | github_block | python_no_reason |
#           modal_cost | patent_filed | concept_saved | secret_leak |
#           test_pass | test_fail | sleep | rule_violation | idle
#
# The hook may also pipe JSON tool-context on stdin; we ignore it for now
# (future: parse tool_input to make reactions smarter).
