Two findings from 2026-08-09 were rules a repository must follow that
`prompts/REPO_POLICIES.md` did not yet state, and are now added where a
reader would look: a new or changed check is proven by planting a defect
it must catch; and a change to a separate workflow limited to `main` by
a `branches` list is first run from the feature branch, added to that
list and removed again before merging. The issue records why every
other finding was dropped. The warning against `golangci-lint config
verify` is dropped because sneak ruled on
#40 (2026-08-10) that there is
no config check step and the config is assumed valid; a vendored
`.golangci.yml` stays byte-identical to the canonical copy.
