name: Changelog assembled
description: >-
Assert a release PR's stamped section is exactly what the changelog.d/
fragments it consumed assemble to — the fragments as of the MERGE BASE
are replayed through the assembler's --check and compared byte-for-byte
against the section on HEAD (#116; the fragment flow is #112). Needs the
HISTORY: the caller's checkout must use fetch-depth: 0, or the base ref
will not resolve and strict mode (the default — CI must never skip)
fails red with a message naming that fix. Inapplicable trees — a -dev
tree, a legacy repo with no fragments directory at the merge base — pass
with a NOTICE, never a silent skip.
inputs:
base-ref:
description: >-
The ref the fragment set is read relative to. The default resolves
the event's base branch — the PR's target on pull_request, the
pushed branch itself on push (where the merge base IS HEAD and the
check is vacuous by construction, named honestly in the log).
required: false
default: origin/${{ github.base_ref || github.ref_name }}
changelog:
description: Path to the changelog, relative to the workspace
required: false
default: CHANGELOG.md
fragments-dir:
description: Path to the fragments directory, relative to the workspace
required: false
default: changelog.d
version-source:
description: Where the tree's version lives ("file" or "package-json")
required: false
default: file
strict:
description: >-
"1" (the default) makes an unresolvable base ref a hard failure
instead of a loud skip — a guard that can quietly stop guarding is
the failure shape this family of checks exists to refuse. The local
default in the script itself stays "0", so a plain working-copy run
degrades sensibly.
required: false
default: "1"
