# v1.4.0 publication readback

This retrospective record binds the published GitHub source release to its
merge, tag, archive and isolated installation. It also records the coherence
gap found after publication: the release shipped candidate wording in its
README/release notes and its diagram did not yet show the quick path. The gap
is the reason for the v1.5.0 coherence hardening.

PR #35 passed the Ubuntu and macOS portable-suite checks before merge. The
annotated `v1.4.0` tag dereferences to merge commit
`215c0bb0d6dbfe9b45ecf3202ec198a2c219b3b2` and tree
`7987bb164c18350579ad435798d20ff2b2d2d534`. The post-merge main run also
passed.

The public source archive matched `git archive v1.4.0` file-by-file, contained
exactly fifteen skills and no generated bytecode, passed the validator, 107/107
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. Source publication is verified; client-specific marketplace
loading and runtime behavior remain separately evidence-scoped.

Rollback is to the accepted `v1.3.1` release and its exact merge commit
`d1e0ea761d4bf439973727668ee871e2b367797e`, or to revert PR #35.
