Round-3 PR re-review follow-ups:
LOW — CODEOWNERS missed /scripts/build-plugins-index.mjs and
/wrangler.toml. Both can change the bytes that get signed without
touching the sign step. Replaced the per-file enumeration with /scripts/
catch-all and added wrangler.toml.
HIGH — workflow comment said the post-sign verify step "catches a buggy
or tampered sign-script run". The "tampered" claim was wrong: any
attacker who can edit sign-plugins-index.mjs in a PR can edit the
verify step (and the embedded pubkey) in the same diff. Re-stated as
"catches accidental regressions only — CODEOWNERS is what stops
adversarial edits".
Branch protection on main has been enabled separately via gh API
(force-push + deletion blocked, PR review required, CODEOWNERS
enforced; bypass for repo owner and github-actions[bot] so the
auto-publish workflow keeps working).
