# q65_gate.sh -- Q65's done-means in one command, and the repo-root resolution
# Q65's own addendum asks for.
#
# Two claims, both graded:
#   1. the LEDGER covers the census and grades clean -- that is `CHECK`, which
#      runs the runner's 22-cell selftest, `--check --class gate-run,undeclared`
#      (population coverage, verdict/rc pairing, blob binding) and the Q63 scan;
#   2. NO ROW IS A TIMEOUT. A TIMEOUT row carries no rc, and Q65's done-when is
#      "each of the five carries an rc or a refusal". A ledger that keeps a
#      TIMEOUT row is a ledger with an ungraded verifier, so this gate is red on
#      one -- which is the only reason the check is worth running.
#
# The root is resolved from $0 rather than written down: a gate that `cd`s to an
# absolute host path grades THAT tree from whatever checkout invokes it, which is
# Q62's class and was measured in this very lane (reply 93 defect 1).
#
#   rc 0  census complete, ledger clean, zero TIMEOUT rows
#   rc 1  a fault it graded (a CHECK fault, or a TIMEOUT row)
#   rc 2  it could not grade: no git root above $0, or no ledger
