docs: prebuilt CI deps — ADR-0049 + CLAUDE.md refresh - #282
Merged
Conversation
The wheel matrix no longer recompiles Boost/eigenpy per run; deps are prebuilt once per toolchain (Linux = GHCR image, macOS = release tarballs, Windows = conda-forge) and consumed by CI. Document it: - ADR-0049: why an image / tarballs / conda per platform; the toolchain-key tag as the ABI assert; single-sourced versions (.github/ci-deps-versions.env) that retrigger the prebuild; why NOT actions/cache (10 GB ceiling); the empty-matrix guard; parallel matrix+assemble. - CLAUDE.md: fix the now-stale claims -- Boost.Python/eigenpy prebuilt (not per-run), the custom ghcr.io/bertiniteam/b2-manylinux-deps image (not stock manylinux), VERSION file (not pyproject) as the version source, and 0-skiptests via bundled OpenMPI + mpi4py.

The changelog had drifted badly: the last entry was **2.0.1**, while **2.0.2**, the entire **3.0.0** modernization, and the **3.1.0** line had all shipped — with their notes living only in commit messages, PRs, and GitHub Releases. This consolidates them back into `CHANGELOG.md`, newest-first, in the existing *Keep a Changelog* format. ### New entries - **[3.1.0] – 2026-07-09** — NumPy interop for the mp dtypes (#306), the Python UI quality-of-life batch (#293–#304, #305), `ZeroDimConfig.recall` (#308), prebuilt CI deps (ADR-0049, #282), and docs-store Pages (ADR-0050, #291, #292). - **[3.0.0] – 2026-07-07** — reworked from the hand-written v3.0.0 release notes (~70 PRs; full themed index in #238) into Added / Changed / Fixed sections. - **[2.0.2] – 2026-05-22** — the packaging/CI maintenance entry that was never recorded. Older 1.0.x / 2.0.1 entries and the commented template are untouched. ### Why now (load-bearing) `publish.yml`'s `github-release` job builds the release body from the **top** `CHANGELOG.md` block. That block was the stale **[2.0.1]** — so a final `v3.1.0` tag would have published 2.0.1's notes as the 3.1.0 release. With this merged, the extraction yields exactly the **[3.1.0]** block (verified locally against the workflow's extraction logic). Docs-only (`**/*.md` → `paths-ignore`), so this runs no CI. **Merge before tagging `v3.1.0`.**
