PR #33 passed the Ubuntu and macOS portable-suite checks before merge. The
annotated `v1.3.1` tag dereferences to merge commit
`d1e0ea761d4bf439973727668ee871e2b367797e` and tree
`1c5c34fd2560f0a4e39e0c05085d350eb404997e`. The post-merge main run also passed.

The public source archive matched `git archive v1.3.1` file-by-file, contained
exactly fifteen skills and no generated bytecode before scanning, passed both
validators, 105/105 tests, Python and shell syntax checks, and the source
Gitleaks scan. A copy installation into an isolated `agents` destination matched
all fifteen source skill files. The source channel is published; client-specific
marketplace loading, automatic alias routing, production behavior and buyer
usefulness remain separate unverified evidence levels.

Rollback is to the accepted `v1.3.0` release and its exact merge commit
`8ae4a26548ce908fc5f98b22663f52e163541f56`, or to revert PR #33.
