PR #31 passed the Ubuntu and macOS portable-suite checks before merge. The
annotated `v1.3.0` tag dereferences to merge commit
`8ae4a26548ce908fc5f98b22663f52e163541f56` and tree
`726162390429c18db8c504833a502aeb0db09d41`. The GitHub release is published,
not draft and not prerelease; GitHub reports it as non-immutable. Client
marketplace and runtime compatibility remain separate evidence levels. The
published source archive was downloaded, matched against `git archive v1.3.0`,
passed the validator, 102-test suite and secret scan, and installed into a
fresh Codex copy destination; all 15 installed `SKILL.md` files matched the
archive.
