# git-cliff config for club-3090 — generates GitHub Release notes from
# commits since the last tag. Categorizes by conventional-commit prefix
# OR by content keywords (cliff/regression/pin-bump). Both direct-to-master
# commits and squash-merged PRs flow through the same parsers.
#
# Workflow: tag with CalVer (`git tag v2026.MM.DD && git push origin v...`)
# → .github/workflows/release.yml runs → git-cliff generates the body
# → release published.

[changelog]
# Header rendered once at top of CHANGELOG.md (preserved across full regens).
# Use `--strip header` on `--latest` for GitHub Release bodies so they don't
# duplicate this intro on every release page.
header = """
# Changelog

Auto-generated from commit subjects by [git-cliff](https://git-cliff.org/) on tag
push. Click any commit SHA below to see the full message body (why / how /
validation data) — those live in `git log`, not here. Don't hand-edit; the file
is regenerated on every tag.

**Versioning:** SemVer in `0.x` — treat any minor bump as potentially breaking
until `1.0`. Past CalVer tags (`v2026.05.09`, `v2026.05.10`) are preserved for
history; SemVer takes over from `v0.3.0` onward.

| CalVer tag | SemVer equivalent | Date |
|---|---|---|
| `v2026.05.09` | (≈ v0.1.0) | 2026-05-09 — first tagged release |
| `v2026.05.10` | (≈ v0.2.0) | 2026-05-10 — stack reorg + Gemma 4 INT8 PTH unblock |
