* feat: broaden CPU and platform coverage across PyPI, nodes, and crates.io
Replace static SIMD with runtime CPU-feature dispatch and expand the release
wheel matrix so one set of artifacts runs on any target CPU and platform
without illegal-instruction crashes.
Rust core:
- Add multiversion runtime dispatch (crates/ferro_ta_core/src/simd.rs); drop
compile-time `wide`. `simd` feature is now default-on and forwarded through
the pyo3 crate, and stays compatible with #![forbid(unsafe_code)].
Packaging:
- abi3-py310: one cp310-abi3 wheel per platform (covers CPython 3.10+).
- CI matrix adds Linux aarch64 + musllinux (x86_64/aarch64) and Windows arm64.
Node/Docker + docs:
- api/Dockerfile: document baseline+dispatch (no target-cpu pin) and add a
fail-fast import check; aarch64 containers now install cleanly.
- Rewrite docs/guides/simd.md; fix stale `wide` mention in ADR 0003.
- Add ADR 0006 (CPU coverage strategy).
Also bundles in-flight release prep already staged in the tree (DTW exception
types, SBOM/provenance security, supporting docs).
* fix(ci): clear cargo-deny and pip-audit failures; apply dependency bumps
cargo-deny (advisories):
- Ignore pyo3 RUSTSEC-2026-0176 / RUSTSEC-2026-0177 in deny.toml with a
documented rationale: ferro-ta uses neither affected code path
(PyList/PyTuple nth iterators; PyCFunction::new_closure). Upstream fix
needs pyo3 >=0.29 (large API migration), tracked as a follow-up.
pip-audit:
- Bump dev lockfile idna 3.18, pytest 9.1.1, urllib3 2.7.0 to clear
PYSEC-2026-215, CVE-2025-71176, PYSEC-2026-141/142.
Dependency bumps (supersede open dependabot PRs; they auto-close on merge):
- cargo: log 0.4.32, serde_json 1.0.150, rayon 1.12.0
- api/requirements.txt: uvicorn>=0.49.0, pydantic>=2.13.4, ferro-ta>=1.1.4
- CI actions: deploy-pages v5, upload-pages-artifact v5, action-gh-release v3
The open `wide` 1.5.0 bump (PR #24) is obsolete — the crate is removed in
this branch.
* chore: address CodeRabbit review; remove docs/adr section
CodeRabbit findings:
- CI sbom job: add `attestations: write` so attest-build-provenance can run
(it had only contents:write + id-token:write).
- simd.rs: vectorize `wma_seed` with lane-local accumulators — it was scalar
behind the multiversion wrapper, adding dispatch overhead for no SIMD gain.
- CHANGELOG: consolidate the duplicate `### Changed` heading.
- python/ferro_ta/__init__.py: also re-export the `FerroTaError` alias.
- docs/guides/dtw.md: soften "byte-for-byte" parity to within-tolerance.
Remove docs/adr/ at maintainer request and clean up the ADR links in the
SIMD and DTW guides. The ADR files remain in commit 9506a30 if ever needed.
Refresh the benchmark and performance surface across the repo. This updates the benchmark wrappers and helper scripts, regenerates the checked-in benchmark and perf-contract artifacts, and folds in the related roadmap, compatibility, and example notebook changes that belong with this performance-focused pass.
Harden the Python CI and local pre-push flow so the same checks pass reliably in both places. The workflow and pre-push script now use module-safe uv typecheck invocations, the Python test environment installs the optional MCP dependency needed by the MCP server tests, and one-off root benchmark outputs are ignored to keep the repo clean.
Align local tooling with the current project configuration by updating the Ruff pre-commit hook, tightening the API typing and MCP server helpers, and refreshing the lockfile to pick up the audited PyJWT fix while preserving the rest of the staged source changes.
