Summary

Production Semgrep scans inherited default exclusions that skipped ordinary
tests, and mixed-exponent determinant properties silently ignored unexpected
errors. Repository-owned ignore rules now include Rust and Python tests while
excluding deliberate rule fixtures; determinant properties explicitly accept
documented outcomes and fail on every other error.

The changes also verify that stale release targets cannot upload artifacts,
avoid copying the scanner environment into benchmark fixtures, and align newly
scanned tests with their intended policies. Documentation now describes exact
determinant row scaling, current tool-pin ownership and benchmark capacity, and
the completed v0.5.0 release. Package versions remain unchanged.

Validation

  • Final just ci passed on macOS arm64: 161 Python tests, 1,031 Rust tests,
    default/exact doctests, examples, benchmark compilation, documentation,
    configuration, spelling, and static analysis.
  • Default and exact-feature package dry runs passed, each packaging and
    verifying 114 files with upload skipped.
  • Production target inspection selected ordinary Rust, Python, and comparison
    tests and excluded all 14 intentional rule fixtures.
  • Independent review of all 15 changed files found no further correctness
    defects. Hosted checks must validate this PR commit; earlier green native
    results covered the committed baseline only.

Review follow-up

The DOI validator returned metadata/context mismatches. Primary-source review
confirmed the existing scholarly publication years and software DOI identity;
the failed executions remain recorded. The validator issue is tracked in
acgetchell/dotfiles#217, and reporting of baseline-versus-repair hosted CI is
tracked in acgetchell/dotfiles#218. The review record is not formally certified.

Historical v0.4.4/v0.4.5 benchmark compatibility and an optional redundant
minimum-normal return branch remain deferred. Neither is a mathematical
correctness defect in these changes or a blocker for v0.5.0-to-v0.5.1 comparisons.

Summary by CodeRabbit

  • Documentation

    • Updated mathematical, benchmarking, coverage, code organization, and release roadmap documentation.
    • Clarified release status, supported Rust version, performance estimates, scaling guidance, and exact numerical conversion behavior.
    • Updated links and guidance for coverage tooling and static-analysis fixtures.
  • Tooling

    • Refined static-analysis scanning to include relevant tests while excluding fixtures, dependencies, generated files, and other non-production paths.
  • Tests

    • Strengthened validation for static-analysis targets, release safeguards, numerical edge cases, and performance-related workflows.

- Include ordinary Rust and Python tests in production Semgrep scans while
  keeping deliberate rule fixtures in their dedicated checks.
- Reject unexpected errors in mixed-exponent determinant properties and
  verify stale release targets cannot upload artifacts.
- Keep scanner environments out of benchmark fixtures and align test code
  with the expanded static-analysis coverage.
- Correct exact row-scaling documentation, benchmark capacity estimates,
  coverage tool ownership, and the released v0.5.0 roadmap.

📝 Walkthrough

This pull request defines Semgrep production scan boundaries and validation, records the v0.5.0 release and tooling data, and updates numerical documentation and test handling.

Changes: Semgrep scan configuration

Layer / File(s) Summary
Production scan policy
.semgrepignore, semgrep.yaml, justfile, docs/code_organization.md
Ignore rules and Semgrep configuration define excluded paths. Documentation describes the policy, and the repository recipe removes a path-specific exclusion.
Scan target validation
scripts/tests/test_maintenance_integration.py, scripts/tests/test_performance_workflow.py
An integration test checks included and excluded production targets in local and SARIF modes. Performance workflow tests adjust fixture setup and a README assertion.

Release records and tooling documentation

Layer / File(s) Summary
Release status and stale-target checks
docs/roadmap.md, scripts/tests/test_release_baseline.py
The roadmap records v0.5.0 as released and its release sequence as complete. The stale-target test verifies that a commit mismatch produces no upload request or publication.
Toolchain and runtime records
docs/MEASURING_COVERAGE.md, docs/BENCHMARKING.md, pyproject.toml
Documentation identifies shared toolchain sources and updates suite counts and runtime estimates. The required uv version changes to 0.13.2.

Numerical documentation and tests

Layer / File(s) Summary
Determinant and decomposition documentation
REFERENCES.md, src/exact.rs, src/lib.rs
Documentation describes per-row exponent scaling, separate solve scales, and shifted magnitude extraction. The mathematical-basis link points to the current repository path.
Numerical test checks
tests/proptest_exact.rs, tests/rational_allocations.rs
The determinant-filter property test distinguishes successful, unavailable, expected non-finite, and unexpected outcomes. The allocation measurement explicitly drops the solve result.

Priority: ⬇️ Low

Estimated code review effort: 3 (Moderate) | ~20 minutes

Change: Bug fix

Possibly related issues

Merge Risk: ⚪ Minimal · up to 789b3

This change adjusts scan configuration, test checks, documentation, and a tooling version pin. The benchmark workflow still selects the newly required uv version where it runs against the project, so no merge-blocking issue remains.

- Around line 1-3: Update the root .semgrepignore to preserve Semgrep’s non-test
default exclusion patterns while continuing to include ordinary Rust and Python
tests; ensure paths such as dist/, .env/, _build/, and *_test.go remain
excluded. Extend the target-selection test to verify these restored exclusions
in both local and SARIF scan selections.

- Preserve Semgrep default exclusions while including ordinary Rust and
  Python tests in local and SARIF scan selections.
- Parse release-fixture URLs before matching GitHub's upload hostname.
- Require uv 0.13.2 and refresh the cc and find-msvc-tools lockfile entries.
