fix(release)!: finalize v0.4.6 and preserve benchmark history - #245
Merged
Conversation
- Complete the v0.4.6 release PR with updated crate and utility package versions, citation metadata, release documentation, and roadmap - Generate the release changelog with complete breaking-change descriptions, preserved Rust code formatting, and idempotent summary generation - Refresh README benchmark assets and the v0.4.6 versus v0.4.5 report - Preserve every measured local benchmark case in versioned CSV snapshots with means, medians, confidence intervals, sample counts, and provenance - Regenerate reports and README assets after cleanup or artifact-only commits without rerunning benchmarks - Publish reports, snapshots, and the latest pointer atomically; reject incomplete inputs, mismatched provenance, and overlapping output paths - Isolate nalgebra/faer dependencies in the comparison workspace package so exact benchmark builds do not compile peer libraries - Reuse baseline peer measurements and disable unused Criterion HTML generation to avoid missing-sample errors in filtered runs - Fix shared-harness target resolution and exact-solve compatibility with supported historical releases - Use faer's native dot-product kernel under a distinct benchmark identity - Remove v0.4.3 adapters, missing-row exemptions, and legacy benchmark-name substitutions while preserving historical reports - Archive the previous performance report and completed optimization studies - Fix cargo-upgrade version detection during setup BREAKING CHANGE: New release performance comparisons require v0.4.4 or newer on both sides. Direct Cargo invocations of vs_linalg must select -p la-stack-comparison; the just recipes handle this automatically.

Inline comments:
In `@scripts/benchmark_summaries.py`:
- Around line 181-182: Update the CSV payload handling near _parse_rows in
summary_outputs to normalize line endings before digest validation: decode the
file as UTF-8 text, normalize newline sequences to LF, then encode the
normalized text as UTF-8 for hashing. Regenerate the retained snapshot so it
matches the normalized representation.
In `@scripts/tests/test_justfile_discoverability.py`:
- Around line 72-73: Update the benchmark discovery logic in just_recipes() and
its current_commands consumer to extract command bodies directly from
just_recipes() rather than filtering raw dry-run output for lines beginning with
“cargo bench ”. Preserve the existing benchmark comparison behavior while
ensuring command-prefix or formatting changes do not silently omit recipes.
In `@scripts/tests/test_postprocess_changelog.py`:
- Around line 576-591: Ensure git-cliff is installed at its pinned version
before the test invoking run_safe_command, and add the same prerequisite to
every Python-test entry point, including just test-python and just ci, so the
test is not skipped or run without the required binary.
