# doctrine coordination-worktree pre-commit backstop (SL-228 PHASE-02, design §7).
#
# Installed per-worktree by `dispatch setup` (via a worktree-scoped `core.hooksPath`).
# Runs on ANY `git commit` in a coordination worktree, any harness — parity by
# construction. It refuses the ISS-234 funnel-reversion signature (mass deletions +
# modification-only reverse-diffs), then CHAINS to the operator's effective non-worktree
# hook so a global/local pre-commit keeps firing.
#
# The signature check lives in Rust (`doctrine dispatch hook-check`) — unit-testable,
# bounded by the FUNNEL_MARKER provenance walk. Binary absent ⇒ fail-closed REFUSE
# (never degrade to deletion-only), UNLESS the operator's deliberate escape hatch is set.

# BEFORE the binary check so a deliberate commit is never blocked by a missing binary.
