From 4f28d4eb64cae42ab4e358008d45d566729bd32b Mon Sep 17 00:00:00 2001 From: ChuckBuilds Date: Sun, 2 Aug 2026 18:03:47 -0400 Subject: [PATCH] fix(version): make the core version have exactly one answer Plugin compatibility floors compare against src.__version__, so that string has to be trustworthy. It has not been. v3.1.0 was tagged 2026-05-31 while src/__init__.py still said "1.0.0"; the bump did not land until 2026-07-12. Every device installed from that release reports 1.0.0, which is below the (2, 0, 0) floor in PluginLoader._warn_if_incompatible -- so those users are silently exempt from every plugin compatibility warning. web_interface carried a third answer, a hardcoded "3.0.0" that nothing read and that had drifted two majors from the core. It now re-exports the canonical value, so it cannot disagree again. Adds: - test/test_version_consistency.py (enrolled in the core unit CI job): src.__version__ is parseable semver, matches the newest CHANGELOG heading, the CHANGELOG's headings are unique and descending, and web_interface tracks the core. src.plugin_system.__version__ is deliberately excluded -- it versions the plugin API and moves independently. - scripts/check_release_version.py + a release-version-check workflow that asserts the tag, the CHANGELOG and src.__version__ agree. Runs on pushed v* tags and published releases, and via workflow_dispatch so a tag can be checked *before* it is created: python scripts/check_release_version.py v3.2.0 Verified: 757 core unit tests pass including the four new ones; the script exits 0 for v3.2.0 and non-zero for both a mismatched tag (v3.1.0) and a non-semver one (v2.5); web_interface and web_interface.app still import. Prerequisite for cutting v3.2.0 -- phase B4 in docs/SPORTS_UNIFICATION.md.
