# ─── Install-ordering guard for settings.json (#869 Point-1 C2) ─────────────
#
# settings.json is where #828's enforcement hooks (PreToolUse mutator-gate.py,
# Stop receipt-observer-client.py) get wired unconditionally. Before copying
# it, delegate to `mosaic __link-claude-settings` (packages/mosaic/src/commands/
# install-ordering-guard.ts) so the wiring decision is made by importing the
# C1 activation probe (`leaseEnforcementActivatable()`) directly, rather than
# re-implementing the capability/supervisor checks in shell. That subcommand:
# - activatable -> writes settings.json with hooks intact, exits 0
# - NOT activatable -> writes settings.json with hooks STRIPPED,
# prints an actionable message, exits 1
# - NOT activatable + opt-out -> writes settings.json with hooks intact,
# prints a loud warning, exits 0
# The `mosaic` CLI is expected on PATH at this point ("No executables are
# placed on PATH — the mosaic npm CLI is the only binary", per install.sh).
# If it is not resolvable at all, that is itself strong evidence the
# activation half is absent, so the same fail-loud default applies via a
# minimal python3 fallback (this repo already depends on python3 for the
# lease broker itself).
