# post-commit-ops-log — record who committed, by althing handle.
#
# WHY. Two agents (infra-ops and infra-hermes) share ONE checkout of this repo
# on nh3-dev, and every commit here is attributed to Vuong Hoang by convention.
# So a commit's author line says nothing about which agent made it. The ops log
# closed this for HOST changes; it did not cover commits to the shared tree.
#
# Found the hard way on 2026-09-19: commit e43e262 appeared interleaved between
# two of this session's commits, in this session's own reflog, and was
# unattributable from git, from the ops log AND from the althing bus. It was
# sitting in the push set at the time.
#
# Appended to .git/hooks/post-commit, which already carries the graphify hook.
# Best-effort by construction: a failure here must never fail a commit.
