  • Replace six Python helpers and local packaging with research-repo-tools 0.1.9 and declarative tooling configuration.
  • Retain only scientific policy and release adapters, with typed catalog parsing and source/harness publication checks.
  • Share benchmark discovery, baseline verification, reporting, plotting, and release publication while preserving historical artifacts.
  • Retire local console entry points and partial raw-Criterion plotting in favor of documented just recipes and complete-run evidence.
  • Target Python 3.15 while isolating Semgrep on locked Python 3.14 for local scans, fixtures, and SARIF.
  • Refresh development dependencies and document the migration.

Closes #276

Summary by CodeRabbit

  • New Features
    • Benchmark comparisons now include all available results, and dimension-based plots can be generated from retained benchmark runs.
    • Release benchmark checks validate saved samples against the configured inventory before publication.
  • Documentation
    • Updated guides explain comparison reports, plot outputs, retained evidence, and publication requirements, with guidance on supported benchmark dimensions and metrics.
    • Documentation now identifies legacy snapshot and raw-Criterion plotting workflows as retired.
  • Maintenance
    • Python support tooling now targets Python 3.15; the Semgrep scanner uses a separate Python 3.14 environment.

- Replace six Python helpers and local packaging with research-repo-tools
  0.1.9 and declarative tooling configuration.
- Retain only scientific policy and release adapters, with typed catalog
  parsing and source/harness publication checks.
- Share benchmark discovery, baseline verification, reporting, plotting,
  and release publication while preserving historical artifacts.
- Retire local console entry points and partial raw-Criterion plotting
  in favor of documented just recipes and complete-run evidence.
- Target Python 3.15 while isolating Semgrep on locked Python 3.14 for
  local scans, fixtures, and SARIF.
- Refresh development dependencies and document the migration.

Closes #276

📝 Walkthrough

The pull request adopts research-repo-tools==0.1.9 for performance and release workflows. It moves benchmark inventories and scientific policy into tooling/, adds retained-evidence plotting, and separates support scripts on Python 3.15 from Semgrep on Python 3.14.

Changes: Performance tooling and evidence

Layer / File(s) Summary
Declare benchmark and evidence policy
tooling/*.toml, tooling/performance.toml, scripts/performance_runs.py, docs/code_organization.md, docs/dev/performance-tooling-adoption.md
Configuration now declares benchmark inventories, saved samples, scientific selection and compatibility rules, plot settings, and legacy CSV mappings. Documentation records the shared-tool ownership boundaries.
Build and validate benchmark runs
scripts/performance_runs.py, scripts/archive_performance.py, scripts/bench_compare.py, scripts/benchmark_contract.py, scripts/benchmark_summaries.py, scripts/performance_artifacts.py, scripts/release_baseline.py, scripts/tests/*, justfile, pyproject.toml, scripts/README.md
Benchmark selection, discovery, and validation use configured policy and shared tooling. Local comparison, artifact, summary, and inventory implementations and their tests were removed or replaced.
Render retained evidence and dimension plots
scripts/archive_performance.py, scripts/criterion_dim_plot.py, scripts/tests/test_criterion_dim_plot.py, scripts/tests/test_performance_workflow.py, tooling/performance-plot.toml, tooling/performance-legacy.toml, docs/BENCHMARKING.md, justfile, scripts/README.md
The archive tool adds retained-evidence plots with CSV, SVG, and provenance outputs, plus optional README and asset-link updates. Tests cover publication checks and legacy conversion. Documentation distinguishes complete-run evidence from frozen historical records.

Benchmark release handoff

Layer / File(s) Summary
Capture and publish the release target
.github/actions/prepare-release-benchmarks/action.yml, .github/workflows/release-benchmarks.yml, scripts/tests/test_release_baseline.py, justfile, docs/RELEASING.md, docs/BENCHMARKING.md
The workflow inventories suites before input validation, delegates release-target validation and asset publication to the shared CLI, and passes its captured target to the publisher. Integration tests check target handoff and tag-commit behavior.

Python and Semgrep environments

Layer / File(s) Summary
Separate support and scanner environments
.python-version, tooling/semgrep/*, pyproject.toml, .github/workflows/semgrep-sarif.yml, .github/dependabot.yml, CONTRIBUTING.md, SECURITY.md, AGENTS.md, scripts/tests/test_maintenance_integration.py, scripts/tests/test_toolchain_integration.py, Cargo.toml
Support scripts use a dependency-only Python 3.15 environment. Semgrep uses a separate locked Python 3.14 project pinned to 1.180.0. Related dependency, audit, monitoring, and integration-test settings were updated.

Explanation

The implementation matches the coding objectives in #276. It pins registry research-repo-tools==0.1.9, records wheel and sdist hashes, removes the six local helpers, adds declarative tooling/ configuration, preserves scientific policy and historical artifacts, and adds installed-package integration checks. The adoption record reports before/after Python and test counts and documents the retirement conditions. The repository evidence does not establish the required Linux, macOS, and Windows consumer CI results for the exact adoption commit or provide linked run evidence. The record explicitly says that issue closure still requires this evidence.

using policy.minimum_release to derive the required version, so the diagnostic
stays aligned with the parsed policy threshold instead of hard-coding a release.

- Keep README asset provenance tied to validated retained runs across
  scratch cleanup while preserving input freshness checks.
- Reject non-canonical storage paths for release-report benchmarks.
- Handle Git execution failures through the plotting CLI diagnostic.
- Derive the minimum supported release diagnostic from the parsed policy.
