1.0.60 removed public API (CultInspectorAssetPath) under a patch bump; its
own changelog says "Breaking" and the version number lied. Operator ruling:
semver is policy, strictly, for every published package family.
docs/semver-policy.md states what counts as breaking per surface (managed
API, Unity inspector attributes, CultCache wire format/store compatibility,
CultNet protocol, native bridge exports), the 0.y.z pre-1.0 convention, tag
naming, and required changelog shape. Records the 1.0.60 scar as history;
does not renumber it.
scripts/check-changelog-semver.mjs is the mechanical check: refuses a
changelog "### Breaking" section under too small a bump, and refuses a
version that skips, reverses, or repeats the previous published tag. Skips
re-litigating a version that is already tagged (rebuilding immutable
history is not a release action). Wired into publish-packages.yml for the
four npm/PyPI packages, and into build-unity-package.ps1 (cultlib),
packages/cultmath/scripts/build-unity-package.ps1 (cultmath), and a new
scripts/verify-caching-unity-release.ps1 (caching.unity has no build script
of its own to hook into).
18 node:test cases cover the required table (breaking+major/minor/patch,
non-breaking, 0.y.z, skip, downgrade) plus CLI-level git-tag resolution.
Hand-mutated each rule (bump classification, pre-1.0 lane requirement,
breaking-heading detection, breaking early-return, already-published skip)
and confirmed each kill, then restored byte-exact. No mutation harness is
committed; CultLib has none today.
