## Description
Hardens two routine PR-review pain points from the recent open-PR sweep:
- PR Governance reruns could keep validating the stale
`pull_request_target` event body even after the live PR description had
been fixed.
- Main CI model-cache misses could surface as dozens of unrelated
memory-test failures instead of one clear cache-preflight failure.
This intentionally avoids PyPI/package-bloat and release/nightly
workflow changes so the PR stays scoped to review and CI stabilization.
## Type of Change
- [x] Bug fix
- [ ] New feature
- [ ] Documentation
- [x] Refactor
- [x] Tests only
## Changes Made
- Added `--body-file` support to `scripts/pr-governance.py` so workflows
can validate the current PR body rather than stale rerun payloads.
- Updated PR Governance to fetch the live PR body via the GitHub API
before validating template fields.
- Added a CI preflight script that loads the default
sentence-transformer model in offline mode and verifies the expected
embedding dimension.
- Wired that preflight into the sharded CI job before pytest starts,
turning missing/corrupt Hugging Face caches into one early, actionable
failure.
- Added workflow/script regression tests for the live-body override and
model-cache preflight placement.
## Testing
- [x] Unit tests
- [x] Lint/static checks
- [ ] Integration tests
- [ ] Manual testing
### Test Output
```text
uv run --with pytest --with pytest-asyncio python -m pytest scripts/tests/test_pr_governance.py scripts/tests/test_pr_health_workflow.py scripts/tests/test_ci_workflow.py -q
9 passed in 0.04s
uv run ruff check scripts/pr-governance.py scripts/ci/verify_hf_model_cache.py scripts/tests/test_pr_governance.py scripts/tests/test_pr_health_workflow.py scripts/tests/test_ci_workflow.py
All checks passed!
python -m py_compile scripts\ci\verify_hf_model_cache.py scripts\pr-governance.py
# passed
```
## Real Behavior Proof
- Environment: Windows 11, Python 3.13.3, isolated worktree
`C:\git\headroom\.worktrees\stabilization-hardening`.
- Exact command / steps: Ran the focused governance/workflow tests, ruff
on touched Python files, and `py_compile` for the executable scripts.
- Observed result: Governance tests prove a stale event body can be
overridden by the live PR body; workflow tests prove CI validates live
PR body and runs the Hugging Face offline-cache preflight before pytest
shards.
- Not tested: Full GitHub CI before PR creation; that will run on this
PR. The new Hugging Face preflight itself is intentionally not run
locally because it depends on the CI-warmed offline model cache.
## Review Readiness
- [x] I have performed a self-review
- [x] This PR is ready for human review
## Description
Fixes intermittent (`~25-test`) failures in `test` shards caused by a
GitHub Actions cache race between the `prefetch-model` job and the four
parallel `test` shards.
Closes #<!-- no upstream issue number yet -->
## Type of Change
- [x] Bug fix (non-breaking change that fixes an issue)
## Changes Made
- Added `id: restore-hfcache` to the "Restore HuggingFace model cache"
step in the `test` job so its cache-hit outcome is observable.
- Added a conditional "Fallback model download if cache missed" step
immediately after the restore, gated on
`steps.restore-hfcache.outputs.cache-hit != 'true'`. When the cache
misses it runs the same authenticated `snapshot_download` retry loop
that `prefetch-model` already uses (same
`snapshot_download('sentence-transformers/all-MiniLM-L6-v2')`, same
default `~/.cache/huggingface` cache root, same unpinned
`huggingface_hub` — byte-for-byte the warm path's mechanism), with
`HF_HUB_OFFLINE=0` / `TRANSFORMERS_OFFLINE=0` scoped to that step only,
so the model lands where pytest looks before pytest starts.
- `TRANSFORMERS_OFFLINE: "1"` on the actual `pytest` step is unchanged.
- The `prefetch-model` job and shared cache key remain the warm-path
optimisation.
- **Added `.github/workflows/**` to the `code` paths-filter group** (the
gate `test` / `prefetch-model` / `build-wheel` / `lint` read via
`needs.changes.outputs.code == 'true'`). Rationale: a change to *how the
tests run* must be validated by the test suite it governs. Without this,
a PR that only touches `ci.yml` matches only the separate `workflows`
filter, so `code=false` and every test job is **skipped** — a CI change
would merge on a hollow green having never executed the pipeline it
modifies. With this line **this PR is self-validating**: the four `test`
shards and `prefetch-model` actually run and exercise the new cache-miss
fallback path. The separate `workflows` filter is left unchanged.
- Polish: the fallback retry loop no longer sleeps after its final (6th)
attempt — it only backs off when another attempt will follow, saving up
to 30s of wasted runner time on a hard failure.
## Testing
- [ ] Unit tests pass (`pytest`)
- [x] Linting passes (`ruff check .`)
- [ ] Type checking passes (`mypy headroom`)
- [ ] New tests added for new functionality
- [x] Manual testing performed
### Test Output
```text
YAML validation: python -c "import yaml,sys; yaml.safe_load(open('.github/workflows/ci.yml')); print('YAML valid')"
→ YAML valid
pre-commit hooks (Sync plugin versions, ruff, ruff-format, mypy): all Passed/Skipped
```
## Real Behavior Proof
- **Root cause**: GitHub Actions cache is eventually-consistent. The
`prefetch-model` job saves the model under `Linux-models-allMiniLM-v2`.
The four `test` shards are independent runner VMs that restore from that
key concurrently. If a shard reaches the restore step before the cache
entry has propagated to the storage layer it gets a cache miss. With
`TRANSFORMERS_OFFLINE=1` on the runner and no model on disk, any test
that instantiates `LocalEmbedder` (≈25 tests) crashes with
`OSError`/`LocalEntryNotFoundError`. Since only some shards miss per run
the failure appears random.
- **Fix rationale**: The inline fallback approach (adding an `id` to the
restore step + a conditional download step) is the smallest possible
diff — two logical additions inside the existing `test` job, no new
jobs, no new artifacts, no changes to any other job. The alternative
(artifact-based sharing via `upload-artifact` / `download-artifact`)
would have been more reliable but required restructuring
`prefetch-model` and the `test` job more significantly. Given the
existing retry loop in `prefetch-model` already handles transient
HuggingFace failures, reusing it as a fallback is the right call.
- **Validated on this PR**: by adding `.github/workflows/**` to the
`code` filter, the `test` shards (×4) and `prefetch-model` execute on
this very PR and pass — so the modified pipeline is proven, not skipped.
- **Not tested**: a live cache miss is not deterministically
reproducible on-demand (it depends on Actions cache propagation timing);
the fallback is byte-for-byte the prefetch-model job's proven download
path, so its correctness rests on that parity.

## Additional Notes
The `prefetch-model` job is preserved as the warm-path optimisation: on
a typical run the cache hits and the fallback step is skipped entirely
(no extra cost). The fallback only fires on the rare cache-consistency
miss that was previously causing flakiness.
## Description
The `CODE_BLOCK_RE` regex in `scripts/pr-governance.py` expects LF after
the opening fenced code block. PR bodies authored on Windows can arrive
with CRLF line endings, which leaves a `\r` before the `\n` and prevents
`has_test_output()` from detecting a valid Test Output block.
This normalizes CRLF to LF once when loading the pull request body,
before section extraction and code-block matching. A regression test now
verifies that a valid PR body with CRLF line endings still passes
governance.
## Type of Change
- [x] Bug fix (non-breaking change that fixes an issue)
- [x] Tests only
## Changes Made
- Normalize Windows CRLF line endings in `scripts/pr-governance.py`
before regex-based validation runs.
- Added `test_validate_pull_request_accepts_crlf_test_output_code_block`
to prevent regressions.
## Testing
- [x] Unit tests pass (`pytest`)
- [x] Linting passes (`ruff check`)
- [x] Formatting passes (`ruff format --check`)
- [x] New tests added for new functionality

## Real Behavior Proof
- Environment: local Windows 11 checkout, Python 3.13.13.
- Exact command / steps: Converted the known-valid governance test body
to CRLF line endings and passed it through `validate_pull_request` in
the new regression test.
- Observed result: The report is valid with no problems, proving the
fenced Test Output block is recognized after normalization.
- Not tested: GitHub-hosted Windows PR authoring path end to end; the
unit test covers the exact CRLF body shape consumed by the validator.

## Description
The CI lint job (`ruff check .` → `ruff format --check .` → `mypy
headroom`) was red on `main`
and therefore on every open PR, for two unrelated reasons that the early
ruff failure was masking:
1. **ruff**: the lint job installs `ruff` unpinned, and ruff 0.15.17
began enforcing import-block
sorting (`I001`) and formatting that older ruff accepted → `ruff check
.` / `ruff format --check .`
fail on files nobody touched.
2. **mypy**: `headroom/providers/opencode/config.py` had two `return
json.loads(...)` statements in
a function declared `-> dict[str, Any]`; `json.loads` is typed `Any`, so
`mypy headroom` fails
with `no-any-return` (reproduced on mypy 1.20.2 — not a version-specific
quirk).
This restores a green lint baseline and pins both linters so a future
release can't silently break
CI again.
## Type of Change
- [x] Bug fix (non-breaking change that fixes an issue)
## Changes Made
- `.github/workflows/ci.yml`: pin `ruff==0.15.17` and `mypy==1.20.2` in
the lint job.
- Applied `ruff check --fix .` (6 `I001` import-sort fixes) and `ruff
format .` (10 files) across
the repo — import ordering and whitespace only, no behavior change.
- `headroom/providers/opencode/config.py`: narrow both
`_parse_json_loose` return sites with an
`isinstance(parsed, dict)` guard, so the `dict[str, Any]` annotation is
true at runtime
(non-dict JSON falls back to `{}`) and mypy's `no-any-return` is
resolved.
## Testing
- [x] Unit tests pass (`pytest`)
- [x] Linting passes (`ruff check .`, `ruff format --check .`, `mypy
headroom --ignore-missing-imports`)
### Test Output
```text
$ python -m ruff check .
All checks passed!
$ python -m ruff format --check .
913 files already formatted
$ python -m mypy headroom/providers/opencode/config.py --ignore-missing-imports
Success: no issues found in 1 source file
$ python -m pytest tests/test_providers_opencode_config.py -q
37 passed
```
## Real Behavior Proof
- Environment: Windows 11, Python 3.13, ruff 0.15.17, mypy 1.20.2,
branch ci/fix-ruff-lint off
headroomlabs-ai/main
- Exact command / steps: reproduced the red lint (latest ruff: 6 `I001`
+ 10 unformatted files;
the mypy failure was read from the #1295 CI lint log —
`config.py:125,133 no-any-return`, and
re-confirmed locally on mypy 1.20.2). Applied the ruff auto-fix/format,
added the dict guard,
pinned both linters, and re-ran each lint step.
- Observed result: `ruff check .` → "All checks passed!"; `ruff format
--check .` → "913 files
already formatted"; `mypy` on the fixed file → "Success: no issues
found"; full `mypy headroom`
reports only Unix `fcntl` attributes that don't exist on this Windows
box (present on the Linux
CI runner, where the prior run showed exactly the two now-fixed errors).
37 opencode-config
tests pass.
- Not tested: did not run the full OS/Python test matrix — the change is
formatting + two CI
dependency pins + a two-line type-narrowing guard, with no runtime
behavior change for dict JSON.

## Description
Makes PR workflow runs more selective by routing docs-only changes to
docs validation instead of the full CI workflow, while preserving
workflow validation and existing code/e2e/release gates for applicable
changes.
## Type of Change
- [ ] 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)
- [ ] Documentation update
- [ ] Performance improvement
- [x] Code refactoring (no functional changes)
## Changes Made
- Added `pull_request.paths-ignore` to `.github/workflows/ci.yml` so
docs/wiki/markdown-only PRs do not queue the general CI workflow.
- Removed `.github/workflows/ci.yml` from the CI internal `code` path
filter so CI-only workflow edits can run workflow validation without
forcing Python/Rust code jobs.
- Added a docs PR validation job to `.github/workflows/docs.yml` for
`docs/**`, `wiki/**`, `mkdocs.yml`, and docs workflow changes.
- Reduced default docs workflow token permissions to `contents: read`,
with `contents: write` scoped only to the deploy job.
- Added docs workflow dry-runs to `scripts/validate-workflows.sh` so
local/CI workflow validation covers the new PR and manual docs paths.
## Testing
- [ ] Unit tests pass (`pytest`)
- [ ] Linting passes (`ruff check .`)
- [ ] Type checking passes (`mypy headroom`)
- [ ] New tests added for new functionality

- Observed result: Changed workflows lint cleanly; docs PR and manual
docs workflow paths dry-run successfully; CI PR dry-run still covers

change.
## Description
`CostTracker._costs` was initialized but never written to, so
`get_period_cost()` always returned `0` and `check_budget()` always
returned "allowed" — the `--budget` flag was a silent no-op.
`_prune_old_costs()` was dead code with zero callers. This makes budget
enforcement actually work: requests are rejected once the configured
limit is reached.
Closes # <!-- no tracked issue; discovered during a proxy-pipeline audit
-->
## 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)
- [ ] Documentation update
- [ ] Performance improvement
- [ ] Code refactoring (no functional changes)
## Changes Made
- **`headroom/proxy/cost.py`** — `record_tokens()` now computes the
request cost via `estimate_cost()` and appends it to `_costs`,
activating `_prune_old_costs()`. When a call site has no API usage
breakdown (cache/uncached all zero), `tokens_sent` is used as the input
count so input cost is not silently dropped. `COST_RETENTION_HOURS` 24 →
744 so retention covers the longest budget period (monthly sums from the
1st; 24h retention would have under-enforced monthly budgets).
- **`headroom/proxy/outcome.py`** — the request funnel passes
`output_tokens` through to `record_tokens()` so costs include output,
for all providers.
- **`headroom/cli/proxy.py`** — added `--budget-period
[hourly|daily|monthly]` (env `HEADROOM_BUDGET_PERIOD`); it existed in
`ProxyConfig` and the server entry point but was unreachable from the
main CLI. Fixed the `--budget` help text that wrongly said "resets at
midnight UTC".
- **`headroom/cli/main.py`** — minor registration/version plumbing.
- Tests: regression coverage for the full `record_tokens →
get_period_cost → check_budget` chain, the `tokens_sent` fallback, and
the `--budget-period` flag/env wiring.

- Exact command / steps: `pytest

-v` — sets `CostTracker(budget_limit_usd=0.0001)`, records ~$1.50 of
Sonnet input, then asserts `check_budget()` returns not-allowed with
`remaining == 0`.
- Observed result: budget is now enforced — `get_period_cost()` reflects
real spend and `check_budget()` rejects once the limit is exceeded (the
proxy returns HTTP 429 on that path). On `main` the same test fails
because `_costs` is never populated and `check_budget()` always returns
allowed.
- Not tested: live end-to-end rejection against a running proxy with
real upstream traffic; the running proxy needs a restart on this version
to pick up the fix.

## Description
Every `test (N)` shard has been failing on all PRs and on pushes to
`main`, even though all tests pass. Root cause: **Codecov retired
tokenless uploads.** Without a token, the upload is rejected with `Token
required because branch is protected`, and `ci.yml` had
`fail_ci_if_error: true` with no token — so the rejected upload failed
the whole shard.
This passes `CODECOV_TOKEN` to the coverage-upload steps so uploads
authenticate again.

- [ ] Documentation update
- [ ] Performance improvement
- [ ] Code refactoring (no functional changes)
## Changes Made
- `ci.yml`: add `token: ${{ secrets.CODECOV_TOKEN }}` to the shard
upload step; guard `fail_ci_if_error` so it stays enforced on same-repo
PRs and pushes but relaxes on fork PRs (which cannot read repo secrets).
- `wrap-native-e2e.yml`, `install-native-e2e.yml`: add the same token so
their coverage uploads authenticate too (these were silently dropping
coverage; already non-fatal).

OK ci.yml
OK wrap-native-e2e.yml

This PR's own `test (N)` shards are the real test: with CODECOV_TOKEN set,
they should upload successfully and go green.
```
## Real Behavior Proof
- Environment: GitHub Actions, `codecov/codecov-action@v5` (ci.yml) /
`@v4` (e2e); repo is public; `CODECOV_TOKEN` repo secret set by the
maintainer.
- Exact command / steps: open this PR → observe the `test (1..4)` shards
upload coverage with the token instead of being rejected.
- Observed result: prior runs showed `1592 passed` then `Token required
because branch is protected` → shard failed; main's own push CI was red
for the same reason. With the token referenced, the upload
authenticates.
- Not tested: fork-PR path (no secret) — by design it now relaxes
`fail_ci_if_error` so the tokenless rejection is non-fatal there.

### New Files
**Tests:**
- `tests/test_dashboard_agent_usage.py` — Covers agent classification,
exact per-request aggregation, and aggregate fallback behavior.
### Modified Files
- `headroom/proxy/server.py` — Adds per-agent usage aggregation to

savings percentage, source, providers, and models.

## Additional Notes
The agent usage panel uses exact request-log data when available. If
detailed request logs are empty, it falls back to aggregate
provider/model request counts and labels the coverage as aggregate
fallback so users are not misled.
## Summary
Closes#920. Follow-up noted in #915.
The dashboard Playwright tests guard on
`pytest.importorskip("playwright...")` and no CI job installs
playwright, so they have skipped on every CI run since they were added —
which is how the bitrot fixed in #915 went unnoticed.
This adds a `test-dashboard-ui` job to `ci.yml`, same shape as
`test-agno`:
- installs the prebuilt wheel `[dev]` + playwright, then `playwright
install --with-deps chromium`
- runs `pytest tests/test_dashboard_*_playwright.py` — the stub-based
tests only (all routes mocked via `page.route`, no network); the glob
also picks up the CVC panel tests from #913 once that merges
- sets `HEADROOM_PLAYWRIGHT_ARTIFACT_DIR` and uploads the captured
dashboard screenshots as a workflow artifact (7-day retention), so every
CI run leaves a visual record of the rendered dashboard
Deliberately excluded: `tests/test_dashboard/test_live_feed.py` — it
navigates to a live proxy on `localhost:8787` and would fail on a runner
with nothing listening. The main test shards keep skipping playwright
tests (playwright stays uninstalled there), so nothing double-runs.
## Testing
- `yaml.safe_load` parses the workflow; the `workflow-validation` CI job
(actionlint + act) runs on this PR since it touches `ci.yml`
- The test this job will run passes locally:
`tests/test_dashboard_cache_ttl_playwright.py` — 1 passed (chromium)
- This PR's own CI run exercises the new job end-to-end

* ci: speed up GitHub Actions - path filters, caching, timeouts, version upgrades
Performance improvements:
- init-e2e.yml, wrap-e2e.yml: add path filters so e2e Docker builds only run when
e2e-related files change (saves ~10 min per irrelevant PR push)
- init-e2e.yml, wrap-e2e.yml: add concurrency groups to cancel superseded PR runs
- ci.yml: add pip caching to lint and build jobs
- ci.yml: cache actionlint + act binaries in workflow-validation (skip curl on hits)
- eval.yml: add pip caching to smoke-test and weekly-suite jobs
- docs.yml: add pip caching for mkdocs-material install
- rust.yml: replace cargo install --locked cargo-audit/deny with taiki-e/install-action
(prebuilt binaries; saves 2-5 min per audit run)
Bug fixes:
- docker.yml: fix actions/checkout@v6 -> @v4 (v6 does not exist; would break all
Docker builds on every release/PR touching docker paths)
Version upgrades:
- wagoid/commitlint-github-action: @v5 -> @v6
- devcontainers.yml: docker/setup-buildx-action@v3 -> @v4 (align with docker.yml)
Safety improvements:
- ci.yml: add timeout-minutes to all 13 jobs (changes, lint, build-wheel,
prefetch-model, test x4, test-extras, test-agno, commitlint, build,
workflow-validation, docker-native-e2e, windows-native-wrapper, macos-native-wrapper)
- docker.yml: add timeout-minutes to docker-build (75m), docker-manifest (20m),
promote-latest (10m)
- eval.yml: add timeout-minutes to smoke-test (30m); bump weekly-suite 60->90m
- rust.yml: add timeout-minutes to test (30m), wheels (45m), audit (20m)
Observed wall-clock impact on recent PRs:
- Init E2E and Wrap E2E were running on every single PR push regardless of content
- CI workflow was taking 12-17 min; path filters reduce unnecessary e2e runs to 0
* fix(ci): bust actionlint+act cache when workflow file changes
Static cache key 'ci-tools-actionlint-act-v1' never invalidated on
tool version updates. Switched to hashFiles('.github/workflows/ci.yml')
so the cache busts automatically whenever the download scripts are
updated to point at a newer release.
Flagged by adversarial review (Architecture + Testing/Reliability personas).
* fix(ci): add missing Dockerfile COPY paths to e2e path filters
e2e/init/Dockerfile and e2e/wrap/Dockerfile COPY files not covered
by the initial path filter set:
init-e2e: Cargo.toml, Cargo.lock, rust-toolchain.toml, uv.lock,
.claude-plugin, .github/plugin/**, plugins/headroom-agent-hooks/**
wrap-e2e: Cargo.toml, Cargo.lock, rust-toolchain.toml, uv.lock,
sdk/typescript/**, plugins/openclaw/**
Without these, a Rust toolchain bump or SDK change on a PR would
skip the e2e gate entirely, only catching it on the merge to main.
Flagged by adversarial review (Domain/Correctness persona).
* fix(devcontainer): upgrade uv to >=0.7.0 to parse uv.lock revision=3
* fix(devcontainer): set UV_SKIP_WHEEL_FILENAME_CHECK=1 in post-create.sh for gitpython wheel
* ci: bump actions/checkout and actions/setup-node to v5 (Node.js 20 EOL Jun 16)
* fix(devcontainer): export UV_SKIP_WHEEL_FILENAME_CHECK so uv run also skips wheel check
* ci: bump all GitHub Actions to latest versions (Node.js 24)
* fix(test): accept release-please-action v4 or v5 in workflow assertion
* fix(format): ruff format test_release_workflows.py
Fold ci-fast.yml into ci.yml: change-detection (paths-filter), build the Rust
ext once (fast cargo profile) shared via artifact, lint once, prefetch the
embedding model once (authenticated) into a shared cache, and run the suite as
4 offline shards. Preserve commitlint, build smoke, workflow-validation, and
the docker/windows/macos e2e jobs (heavy ones gated on paths-filter). CPU-only
torch throughout; least-privilege permissions. Removes ci-fast.yml.
PRs run one Python version x 4 shards; multi-version on main is a follow-up.
Eliminates the dual-package architecture that was the root cause of #355.
`pip install headroom-ai` now produces ONE wheel containing both the Python
source (headroom/*.py) and the compiled Rust extension (headroom/_core.so).
No more separate `headroom-core-py` package, no more chicken-and-egg with
PyPI publication, no more wheelhouse / PIP_FIND_LINKS / composite-action
plumbing in CI.
This is the canonical pattern used by cryptography, polars, ruff,
pydantic-core, and other Rust-as-core Python packages. Honors the
"Rust as core engine" direction.
## What changed
- pyproject.toml: `[build-system]` swapped from hatchling to maturin.
`[tool.hatch.*]` deleted; `[tool.maturin]` added pointing at
`crates/headroom-py/Cargo.toml` for the cdylib. `python-source = "."`
picks up the root `headroom/` package directly (dashboard HTML
templates and other non-Python files included automatically).
- crates/headroom-py/pyproject.toml: deleted. The crate is no longer a
separate published package; its Cargo.toml stays as the cdylib build
target invoked via `[tool.maturin] manifest-path`.
- crates/headroom-py/python/: deleted (placeholder layout for the old
separate package).
## CI updates
- ci.yml: `test` / `test-extras` / `test-agno` jobs simplified — Rust
toolchain set up before `pip install -e .` (which now invokes maturin
via build-system). Removed the "build wheel + symlink .so" dance.
`build` job swapped from `python -m build` (hatch) to
`maturin build` + `maturin sdist`.
- release.yml: collapsed dual-package matrix into one. New `build-wheels`
matrix produces cross-platform wheels for cp310/11/12/13 ×
{linux x86_64, linux aarch64, macos x86_64, macos aarch64}. New
`collect-dist` aggregator merges artifacts. publish-pypi consumes the
merged dist.
- init-native-e2e.yml: dropped windows-latest from the matrix —
upstream `esaxx-rs` (/MT) and `ort-sys` (/MD) link with conflicting
MSVC C runtime libraries, so the Rust extension cannot build for
win_amd64 today. Tracked as a follow-up; not a blocker for Linux+macOS.
- headroom-e2e-setup: composite action now sets up Rust toolchain +
Swatinem/rust-cache before `pip install -e .[proxy]`.
- eval.yml, publish.yml, rust.yml: same pattern — rust toolchain before
install. rust.yml's wheels job builds from root pyproject.toml (no
more `-m crates/headroom-py/Cargo.toml`).
- e2e/init/Dockerfile, e2e/wrap/Dockerfile: install rust + maturin in
the build stage; copy `crates/` + workspace `Cargo.toml/lock` so the
install can build the extension. Dropped `HEADROOM_REQUIRE_RUST_CORE=false`
from wrap-e2e — the image now ships the full Rust core.
- Dockerfile (main): simplified — no more Layer 2/3 dance with
`headroom-core-py` install + symlink. Single `uv pip install` builds
+ installs everything.
- .devcontainer/Dockerfile: rust toolchain + libssl-dev + maturin
added so `uv sync` builds the extension inside the devcontainer.
## Lockfile + script
- uv.lock: regenerated. No `headroom-core-py` entries remain.
- scripts/build_rust_extension.sh: simplified from a symlink-into-tree
workaround to a thin wrapper around `pip install -e .`. The maturin
build-backend handles placement automatically.
## Local validation (all green on macOS aarch64)
1. Clean venv `pip install -e .` → `from headroom._core import …` works.
2. `maturin build --release` → 13.8 MB wheel, 336 files including
`headroom/_core.cpython-311-darwin.so` (32 MB cdylib) and
`headroom/dashboard/templates/dashboard.html`.
3. `pip install <wheel>` in fresh venv → import works.
4. Wheel contents verified via `unzip -l`.
5. `pytest tests/test_transforms/test_diff_compressor.py` — 29 passed.
6. `pytest tests/test_relevance.py` — 30 passed.
7. `cargo build --workspace` + `cargo test --workspace` — all green.
8. `make ci-precheck` — 176 Python tests + Rust + commitlint green.
## Migration notes
Users on `pip install headroom-ai` get the Rust core automatically
(linux + macos wheels). sdist installs require rust toolchain available
locally — pip will build via maturin.
Closes#355
Supersedes #357 (workarounds-based fix abandoned in favor of
architectural fix)
The action was set to @stable, which installs whatever the latest
stable is (1.95.0 right now). Then maturin invokes cargo, which reads
rust-toolchain.toml and re-resolves to "1.95.0 + clippy + rustfmt".
rustup treats stable and 1.95.0 as distinct toolchain identities and
refuses the second install with:
failed to install component 'clippy-preview-x86_64-unknown-linux-gnu',
detected conflict: 'bin/cargo-clippy'
This was intermittent across the matrix (only test (3.10) tripped on
the most recent run; others got lucky on cache state). Pinning the
action ref to 1.95.0 makes both sides ask for the exact same toolchain
identity, so the second install is a no-op and the conflict can't fire.
Bump procedure stays the same: when rust-toolchain.toml's channel
changes, update these refs in lock-step.
Plugin manifests auto-bumped 0.11.0 -> 0.13.2 by sync-plugin-versions
hook (unrelated to the workflow fix).
Five gates broke on the 2026-04-27 push of the smart_crusher branch.
Each is fixed below; the second half adds a `make ci-precheck` target
(plus an installable git pre-push hook) so the same dance never happens
again.
Failures fixed:
1. cargo fmt — 22 files had formatting drift introduced over the
stage 3c.1 work. `cargo fmt --all` reformatted them; no semantic
changes. `cargo test --workspace` still green (388 + supporting).
2. wheels job (macOS x86_64) — `fastembed -> ort -> ort-sys` does not
publish prebuilt ONNX Runtime binaries for `x86_64-apple-darwin`.
Removed that target from `.github/workflows/rust.yml`'s wheels
matrix. Apple Silicon (`aarch64-apple-darwin`) covers macOS
distribution; Intel macOS users can build from source. The matrix
now has 2 targets: linux x86_64 + macOS aarch64.
3. test-extras (relevance.py) — `tests/test_relevance.py::TestSmartCrusherIntegration`
constructs a `SmartCrusher`, which hard-imports `headroom._core`
since the python implementation was retired in stage 3c.1b. The
test-extras job didn't build the rust extension. Added the same
`maturin build + symlink` block the main `test` job uses.
4. smoke-test (eval.yml) — same root cause:
`compression_only.evaluate_ccr_lossless` instantiates a SmartCrusher.
Same fix: build the rust extension before the smoke test runs.
5. commitlint — three rules tripped:
- `subject-case` rejects PascalCase identifiers in subjects, but
the project deliberately names classes (SmartCrusher, HfTokenizer,
ContentRouter, DiffCompressor) in commit subjects. Disabled.
- `footer-leading-blank` is a warning that the wagoid action turns
into a CI failure; lines like `Module: foo.rs` in our bodies
match the conventional footer pattern and trip it. Disabled.
- `type-enum` doesn't include `parity`, but the project ships
parity-test infrastructure as its own concern (separate from
`test:`); added `parity` to the allowed types.
Pre-push verification — the prevention half:
`make ci-precheck` runs all of the above CI gates locally:
- `ci-precheck-rust`: cargo fmt --check + clippy + test --workspace.
- `ci-precheck-python`: builds the rust extension via maturin, then
runs the smart_crusher-affected python test files (185 tests across
test_transforms/, test_relevance*, test_ccr, test_acceptance,
test_critical_fixes, test_quality_retention).
- `ci-precheck-commitlint`: `npx commitlint --from origin/main --to
HEAD` against the same config CI uses. Skipped silently if npx is
not on PATH (install Node 18+ to enable).
`make install-git-hooks` (or `scripts/install-git-hooks.sh`) installs
a git pre-push hook that runs `make ci-precheck` automatically.
Bypass with `--no-verify` only when truly needed.
When new CI gates land in `.github/workflows/`, mirror them into a
`make ci-precheck-*` target. The Makefile is the local mirror of the
CI configuration; keeping them in sync is a load-bearing invariant.
Verification: `make ci-precheck` runs green on this commit.
The previous version of this step did `python -c "import headroom._core"`
to find the wheel's installed `.so` path. That failed in CI:
ModuleNotFoundError: No module named 'headroom._core'
— exactly the chicken-and-egg this step exists to fix. The editable
install (`pip install -e .`) puts the in-tree `headroom/` source dir
ahead of site-packages on `sys.path`. So `import headroom` finds the
in-tree dir (which doesn't yet have the `.so`), then
`import headroom._core` fails to find the submodule. The symlink we're
about to create is what makes the import work — but we can't import
to discover the symlink target before creating it.
Locate the `.so` via filesystem instead: read site-packages from
`site.getsitepackages()[0]`, glob for `_core.cpython-*.so` under
`<site-packages>/headroom/`, and symlink that into the in-tree dir.
The smoke test (`from headroom._core import DiffCompressor`) runs
*after* the symlink and confirms end-to-end resolution.
Also added `set -euo pipefail` and a sanity check with `ls -la` of the
site-packages dir if the glob comes up empty, so future failures
diagnose themselves.
`maturin develop` requires a virtualenv (it errors with "Couldn't find a
virtualenv or conda environment"). CI's setup-python provides a bare
system Python without a venv, so the dev script's build path doesn't
work there.
This switches CI to build a release wheel via `maturin build` and
install it with `pip install --force-reinstall --no-deps`. Then symlink
the installed `.so` into the in-tree `headroom/` package so the
editable install resolves `import headroom._core` past the source-dir
shadowing of site-packages.
`scripts/build_rust_extension.sh` is unchanged — it stays optimized for
local dev (where there IS a venv).
The python `DiffCompressor` was retired in this PR's stage-3b commit;
the public class now delegates to `headroom._core` (built from
`crates/headroom-py`). Without the wheel installed in CI, every test
that constructs a `DiffCompressor` fails with `ModuleNotFoundError:
No module named 'headroom._core'`.
This adds a build step to the main `test` job in `ci.yml` that:
1. Installs the stable Rust toolchain (`dtolnay/rust-toolchain@stable`).
2. Caches the cargo registry and build output (`Swatinem/rust-cache@v2`).
3. Installs maturin.
4. Runs `scripts/build_rust_extension.sh`, which calls `maturin develop`
and symlinks the built `.so` into the in-tree `headroom/` package
so the editable install resolves `import headroom._core`.
Only the main `test` job needs this — `test-extras` and `test-agno`
run narrow subsets that don't construct `DiffCompressor`. The existing
`rust.yml` workflow continues to handle wheel builds for distribution
and `cargo test` for the Rust workspace.
Bring the branch onto upstream/main so GitHub validates the same merged
compression code locally, and install act into PATH for the
workflow-validation job.
This keeps the compact-JSON compression regression fixed while making
the shared validation script pass in CI.

Fix workflow validation failures by wiring detect-version outputs into all
release publish jobs, renaming the GitHub Packages skip variable to a
valid Actions variable name, and adjusting the macOS PATH export for
actionlint.
Also make min_tokens_to_compress use token counting instead of whitespace
splits so compact JSON tool outputs still compress after merging the
latest main branch changes, and add a regression test for that path.
