## Description
Supply-chain hardening: takes the **shipped** dependency surface from
**26 known CVEs to 0**. `pip install headroom-ai[all]` now resolves with
no known vulnerabilities (verified with Anchore syft + grype). Also
publishes a checked-in SBOM package (`sbom/`) so any user — especially
pilots running their own security review — can verify what's inside and
that we track it.
This addresses the Dependabot alerts on `main` (9 high / 4 moderate / 7
low at time of writing).
Closes #
## Type of Change
- [x] Bug fix (non-breaking change that fixes an issue)
- [ ] New feature (non-breaking change that adds functionality)
- [ ] Breaking change (fix or feature that would cause existing
functionality to change)
- [x] Documentation update
- [ ] Performance improvement
- [ ] Code refactoring (no functional changes)
## Changes Made
**Rust**
- `pyo3` 0.24 → 0.29 (GHSA-36hh-v3qg-5jq4 High, GHSA-chgr-c6px-7xpp
Med). Migrated `Python::allow_threads` → `Python::detach` (10 sites) and
added `from_py_object` to the `Clone`-deriving `#[pyclass]` types (both
required by the 0.25+ API).
- `pyo3-log` 0.12 → 0.13; `lru` 0.12 → 0.18 (GHSA-rhfx-m35p-ff5j).
**Python**
- `torch` → 2.12.1, `mem0ai` → 2.x.
- Floor-pinned transitive CVE deps via `[tool.uv]
constraint-dependencies`: `pygments>=2.20.0`,
`pydantic-settings>=2.14.2`, `gitpython>=3.1.50`, `langsmith>=0.9.0`.
- **Removed `benchmark` from the `[all]` aggregate** so the default
install is CVE-free. `lm-eval` is invoked as an external subprocess
(`python -m lm_eval`) and never imported, so it is not a true runtime
dep — it remains available via the opt-in `[benchmark]` extra. See
[Accepted Risks](#additional-notes).
**npm (build/test tooling — never shipped in the
wheel/container/published SDK)**
- `esbuild` override `>=0.28.1` in `sdk/typescript` + `plugins/openclaw`
(GHSA-g7r4-m6w7-qqqr).
- `docs/`: `@anthropic-ai/sdk` → `^0.106.0` (GHSA-p7fg-763f-g4gf),
`postcss` override to force Next.js's bundled copy ≥8.5.10
(GHSA-qx2v-qp2m-jg93); regenerated a stale `bun.lock` that carried a
**Critical** vitest/vite.
**CI**
- Pinned `pypa/gh-action-pypi-publish` `@release/v1` → `@v1.13.0`
(GHSA-vxmw-7h4f-hqxh) in `release.yml` + `publish.yml`.
**SBOM**
- New `sbom/` directory: CycloneDX 1.7 + SPDX 2.3 SBOMs, grype scan
evidence, 330-package license inventory, and a regeneration guide.
## Testing
- [ ] Unit tests pass (`pytest`) — N/A, no Python source changed
(deps/config only)
- [x] Linting passes — `cargo fmt --check` + `cargo clippy` clean on the
changed crate; 0 `.py` files changed so `ruff`/`mypy` scope is
unaffected
- [x] Type checking passes — `cargo check --workspace` (0 errors)
- [ ] New tests added — N/A (dependency bumps; covered by existing
suites)
- [x] Manual testing performed — see Real Behavior Proof

```
## Real Behavior Proof
- Environment: macOS (darwin 25.4.0, arm64), Python 3.12 `.venv`, Rust
1.95 toolchain, syft 1.46.0, grype 0.115.0, bun 1.3.14, maturin 1.13.3.
- Exact command / steps: (1) `uv export --extra all --no-dev
--no-emit-project | syft → grype` for the product surface; (2) `cargo
check --workspace` + `maturin develop` + extension import/compress smoke
test; (3) `cargo test -p headroom-proxy --lib drift`; (4) `cargo fmt
--check` + `cargo clippy -p headroom-py`; (5) `npm audit` in
sdk/openclaw/docs + `bun audit` in docs.
- Observed result: `headroom-ai[all]` resolution scans clean — "No
vulnerabilities found" (179 pkgs); full/prod SBOM shows only the 2
documented accepted CVEs; pyo3 0.29 extension imports and runs (detach +
from_py_object paths exercised); drift tests 14/14 pass; cargo fmt +
clippy clean; all npm/bun audits report 0.
- Not tested: full `pytest` suite (no Python source changed);
release-profile wheel build (used dev-profile `maturin develop` for the
import proof — the extension is semantically identical).

## Additional Notes
**Accepted risks (the 2 residual CVEs).** Both originate solely from the
EleutherAI `lm-evaluation-harness` under the **opt-in `[benchmark]`
extra**, which Headroom invokes as a subprocess (never imports):
- `sqlitedict` CVE-2024-35515 (High) — pickle deserialization; package
abandoned (last release 2021), **no upstream fix exists**.
- `nltk` CVE-2026-54293 (High) — path traversal in `nltk.data.load()`;
affects ≤3.9.4 (current latest), **no patched release**.
Neither is in `[all]`, the published wheel, or the container. They are
documented in `sbom/README.md` and will be picked up automatically once
upstream ships fixes.
**Release/CHANGELOG:** N/A items above are because this is a
dependency/security PR with no Python source changes; CHANGELOG is
Release-Please-managed via the conventional commit message.

# ── Release profile — wheel size optimization ───────────────────────
|
||
#
|
||
# PyPI imposes a 10 GB cumulative storage limit per project. We hit it
|
||
# at version 0.21.36 (191 versions × ~213 MB/release = 10.00 GB
|
||
# exactly). Recent wheels were ~16-18 MB each, of which ~6.4 MB was
|
||
# pure debug metadata (`.strtab` + `.symtab` ELF sections; uncovered
|
||
# by post-mortem inspection of an actual production wheel).
|
||
#
|
||
# This profile shrinks each Linux wheel from ~18 MB → ~10-11 MB by:
|
||
# * Stripping symbol/string tables (~6.4 MB direct savings)
|
||
# * Link-time optimization across crate boundaries (~5-10% .text
|
||
# savings via dead-code elim across the workspace)
|
||
# * Single codegen unit (better inlining + dead-code elim, at the
|
||
# cost of slightly slower release builds)
|
||
#
|
||
# We deliberately do NOT set ``panic = "abort"``. The proxy is a
|
||
# long-lived async process — a single misbehaving request triggering
|
||
# panic-abort would terminate the whole proxy and disconnect every
|
||
# concurrent client. Accept the smaller savings; keep unwind behaviour.
|
||
#
|
||
# Estimated impact: 213 MB/release → ~130 MB/release. Buys ~30+ more
|
||
# release slots within the 10 GB ceiling at the current release
|
||
# cadence. Per-PyPI-version savings AND faster downloads for end
|
||
# users. Tradeoff: release builds take ~30-50% longer due to
|
||
# `codegen-units = 1` + LTO; acceptable for the size win.
