WalkthroughThe change adds real-package and multi-platform benchmark runners for seven solvers. It records solver metrics in JSON files and generates a Markdown report with aggregate rankings, platform details, and dependency analysis. ChangesSolver benchmarking
Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🟡 Moderate · up to This adds benchmark runners and published solver rankings, but the current implementation can produce misleading dependency, correctness, selection, and speed results and 8000 cannot run from a normal checkout.

In `@benchmark_runner.py`:
- Around line 111-113: Update the dependency lookup around
get_dependencies_for_package so it receives the package’s complete Nix store
path, including hash, name, and version, rather than pkg.name with its version
removed. Ensure nix-store -qR uses that full path while preserving the existing
assignment to pkg.depends.
- Line 105: Update run_benchmark so max_packages limits the combined candidate
list from all input sources before scoring and reporting; ensure
benchmark_results.json uses that exact same capped slice for input counts and
selection-rate metrics.
In `@full_benchmark_runner.py`:
- Line 301: Remove the duplicate gcc entry from the NixOS package records near
the _pkg definitions, retaining one complete gcc definition with its existing
dependencies and conflicts. Ensure the first 50 NixOS records contain 50 unique
package records so list-based totals and encoded constraints remain consistent.
- Around line 394-399: Update the unmet-dependency scoring in
full_benchmark_runner.py lines 394-399 and benchmark_runner.py lines 146-150 to
count only dependencies represented in constraints.packages, matching the
dependencies encoded by encode_packages; do not penalize declared dependencies
without package records, and preserve scoring for encoded dependencies.
- Line 403: Retain unrounded elapsed values in the ranking and aggregation data
used by the full benchmark runner, including platform and overall rankings;
apply rounding only when formatting output near the elapsed-time field in
full_benchmark_runner.py:403-403. Make the same change for the single-platform
ranking near benchmark_runner.py:154-154, using the relevant runner
ranking/aggregation logic and preserving raw values until presentation.
- Around line 496-498: Replace the hard-coded machine-specific benchmark and
report paths with one configurable or repository-local path policy. Update
full_benchmark_runner.py lines 496-498 and benchmark_runner.py lines 265-267 to
write results accordingly; update publish_report.py lines 4 and 62-63 to read
the same result path and write the report through the corresponding configurable
or repository-local report path.

394-399: 🗄️ Data Integrity & Integration | 🟠 Major | 🏗️ Heavy liftDo not penalize dependencies that were not encoded.
encode_packagesonly creates a dependency constraint when the dependency is also in the input package set. These loops count every declared dependency instead. For example, the Debian data declares dependencies that have no package record, so every solver receives unmet-dependency penalties for constraints it never received. Add the dependency closure to each dataset, or score only dependencies present inconstraints.packages.

403-403: 🎯 Functional Correctness | 🟠 Major | ⚡ Quick winRank solvers from unrounded elapsed time.
Both runners round elapsed time to four decimals before selecting the fastest solver and before computing averages. Different measurements can become equal after rounding, and dictionary insertion order then selects the reported winner. Keep raw elapsed values for rankings and aggregation. Round only when formatting output.
