about

nx_jrnl_archive_gate.nx -- GATE for nx_jrnl_archive (lib composed in-process, nothing forked). The verb's whole contract is PRESERVE-BEFORE-REMOVE, so the load-bearing teeth are the ones where the archive step FAILS and the live journal must come out byte-identical (T6), and the one where the verify step can actually see a corrupted copy (T10 -- a hash compare that cannot fail is not a verify). Fixtures live under /tmp/nx_jrnl_archive_gate_<pid>/ (data only; nothing is executed from /tmp, which the NAS mounts noexec). license_tier: ORIGINAL No hw writes (Rule 26).
