A named base that does not resolve, or a shallow checkout with no parent, is a fault (exit 2), never an allow. ci now raises lock-allowlist-edited for a change that carries the allowlist, as tool use and agent-commit do; push does not. The finding message now reads for both writers. Tests: test_lockfile_integrity_sr2d2.py. No eval case can drive this: replay has no range base to name."
