# v1.5.0 publication readback

This post-release record binds the published GitHub source release to the PR
#36 merge, annotated tag, source archive and isolated copy installation. The
tag remains bound to the reviewed merge commit. The current `main` documentation
was aligned after tag creation through a separate post-release metadata PR; the
tag archive intentionally retains the pre-publication candidate checkpoint so
the distinction is auditable rather than silently rewritten.

The source archive matched `git archive v1.5.0` file-by-file, contained exactly
fifteen skills and no generated bytecode, passed both validators, 109/109 tests,
Python and shell syntax checks and the source Gitleaks scan. An isolated copy
installation matched all fifteen source `SKILL.md` files. Direct Astra and
Claude Fable 5.1 / Mythos 5.1 runtime support remains unverified; the model
positioning is limited to a portable workflow contract.

Rollback is to the accepted `v1.4.0` release and its exact merge commit
`215c0bb0d6dbfe9b45ecf3202ec198a2c219b3b2`, or to revert PR #36.
