 The selected tarball is built, content-scanned, installed, imported and typechecked before it is retained. The publish step verifies its SHA-256 and publishes that same tarball with lifecycle scripts disabled. Normal `pnpm pack:check` still cleans every temporary file. Optional `pnpm pack:check <package> --output-directory <absolute-directory>` retains one tested tarball for owner inspection or the manual publication workflow; retained files belong outside the repository and must never be committed.
 
 The owner-requested first integration release is `0.0.1` for both packages. It uses the preview publication channel and `preview` dist-tag even though the version has no SemVer prerelease suffix. Its GitHub Releases are marked prerelease. This permits exact-version consumer adoption without claiming the coordinated stable/1.0 gates have passed. The stable channel remains restricted to 1.0.0 and later.

+Main-branch releases require the exact commit's completed CodeQL analysis from `.github/workflows/codeql.yml:analyze`, with no scan errors/warnings and no open CodeQL alerts on main. The PR-only GitHub Advanced Security check is validated when present, but its absence on main does not replace this direct analysis evidence. Publication and Release jobs receive `security-events: read` for these read-only API checks.
