ADR-0028 shipped as proposed in #226. No open questions on drivers,
considered options, or the 4-phase migration sequence - promote to
accepted to unblock Phase 1 (mirror-and-bootstrap).
ADR-0015 gets a status-update blockquote at the top calling out that
the platform choice "Gitea Actions" is superseded by ADR-0028 while
the architectural principles in the rest of ADR-0015 (trunk-based +
squash, all-gates-blocking, thin YAML, on-prem runners, signed
commits, Conventional Commits) carry over unchanged. ADR-0015's
frontmatter status stays accepted - this is the canonical MADR way
to handle partial supersession without rewriting the decision record.
CLAUDE.md CI/CD architecture bullet rewritten to reflect the
accepted-but-not-yet-implemented state. Roll-up bumped to 0001 -> 0028
accepted. Side-fix: the bullet referenced a non-existent `ci:scan`
script; replaced with the real names (ci:catalogue-drift, ci:audit,
ci:perf, ci:gzip-budgets).
No code changes, no ci:check impact.
