# Reads Claude Code's Stop JSON from stdin, delegates claim-scanning to
# hooks/lib/stop_match.py. On a claim-without-evidence match, blocks the
# Stop transition with a "show evidence" message.
#
# V1.0 ships claim detection only. Phase 1.E adds the evidence-search
# helper that verifies whether the claim is actually unsupported before
# the block fires.
