# munteok setup — scaffold a 문턱 substrate (안채) from a fork of this framework.
#
# What it does (framework-owned only):
#   1. Scaffolds private zone content placeholders into THIS repo (your 안채):
#      hearth/identity/{voice,position,relations}.md · desk/agenda/current.md · desk/diary.md
#   2. Installs the 4-zone definition (§munteok) as a marker block into ~/.claude/CLAUDE.md
#
# What it deliberately does NOT do (delegated — run those separately):
#   - memory / notes / device-sync         → bobusang setup.sh
#   - thinking discipline                   → sonmat (plugin install)
#   - device table (§env), per-instance paths, desk↔~/.claude symlink relocation → your call
#
# Idempotent: existing files are skipped; the marker block is updated in place.
# Override target for testing: MUNTEOK_CLAUDE_DIR=/tmp/foo bash setup.sh
