# CHECK — volt lane: the Q65 verifier-coverage gate. Fast: no verifier runs.
#
# What this grades: the LEDGER against the tree at HEAD. Every committed
# wizard-work/**/verify_*.py must be named by the census
# (q63_unwired_baseline.tsv) or by the runner ledger (q65_runner_baseline.tsv),
# every ledger row must be bound to the blob it graded, and every ledger row's
# verdict must agree with the rc beside it. Re-executing the verifiers is
# `q65_runner.py --emit` (minutes, 79 population files of 93 committed
# verifiers) and is not this.
#
# The root is resolved from $0, not written down. A gate that `cd`s to an
# absolute host path grades THAT tree from whatever checkout invokes it: at
# `66e5be1`, a clone with one verifier deleted printed `0 unclassed of 88` and
# CHECK PASS (measured 2026-10-24, reply 93 defect 1). `git -C <this dir>`
# fails outside a repo, which is rc 2 — the gate could not grade, and that is
# not a pass.
#
#   rc 0  the ledger is complete, content-bound and self-consistent
#   rc 1  a fault it graded: an unclassed verifier, a missing row, a bad pairing,
#         a row whose blob no longer matches the tree
#   rc 2  it could not grade at all (no ledger, unreadable tree, no git root)
