# Hook ids aren't unique across scopes, so `pre-commit run <id> --files <paths>`
# runs the one scope whose files: regex matched and prints the same-id siblings
# as "(no files to check)Skipped". The summary table wants one row per linter
# that ran, so we keep only the non-skipped block: a hook name line ending in
# Passed/Failed plus its trailing `- hook id:` / `- duration:` lines.

# Usage: precommit-filter-leg-log.sh <hook-id> <raw-log>   (hook-id is currently
# informational; selection is by Passed/Failed result, which uniquely picks the
# scope that ran.)
