* docs(AGENTS.md): require fresh branch off origin/master per batch Add a "Starting the next batch" subsection to the reverse-DNS-maps workflow. Each batch must start from a fresh checkout of origin/master, not from the previous batch's branch. The trap: if the previous batch's commit has already merged via a PR pushed from elsewhere (a co-worker's session, an unsynced laptop, an earlier session), the local copy of that commit still sits on the old branch. Stacking new work on top makes the new PR conflict with master, because the merged commit and the local copy insert identical map rows at identical sorted positions and the same lines collide. Hit live this batch (PR #749) and recovered via `git rebase --onto origin/master <stale-commit> <branch>` plus a force-push, then a PR-description trim. Documenting the failure mode and the recovery so the next contributor avoids the trap entirely.

Same scenario in mind: a previous batch's PR is still in flight, started from a different machine or session, and starting a new batch in parallel duplicates effort or splits attention across two competing PRs touching the same files. Cheap one-liner; cost of forgetting it is the kind of conflict #749 already documented at the branch-hygiene level.

parsedmarc
parsedmarc is a Python module and CLI utility for parsing DMARC
reports. When used with Elasticsearch and Kibana (or Splunk), it works
as a self-hosted open-source alternative to commercial DMARC report
processing services such as Agari Brand Protection, Dmarcian, OnDMARC,
ProofPoint Email Fraud Defense, and Valimail.
Note
Domain-based Message Authentication, Reporting, and Conformance (DMARC) is an email authentication protocol.
