fix: correct conflict detection from nixpkgs source - #101
Conversation
WalkthroughThe conflict extractor now uses targeted patterns. The generated data removes the previous clang conflict and updates package, platform, and file-level conflict totals to zero. ChangesConflict extraction correction
Priority: ⬇️ Low Estimated code review effort: 2 (Simple) | ~10 minutes Merge Risk: 🔵 Low · up to Conflict reporting now uses narrower Nix markers, but commented or quoted marker text can still be reported as a real conflict, producing inaccurate package and platform totals. This is a bounded data-accuracy risk that should be addressed before relying on the generated results. 🚥 Pre-merge checks | ✅ 4 | ❌ 1❌ Failed checks (1 warning)

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Ignore Nix comments and string literals before matching conflict markers.
These regexes search raw source text. They report a conflict for text such as # meta.broken = true or # notWith = foo;, although neither declaration affects package evaluation. Parse the relevant Nix syntax, or remove comments and strings before matching, so conflict_count only reflects active declarations.
Also applies to: 221-221

1. Broken packages appear to conflict 🐞 Bug ≡ Correctness
extract_conflicts appends the literal assignment meta.broken = true as though it were the name of a conflicting package, despite the project's conflict model requiring two package names. Whenever this marker occurs, the generated dataset increments conflict_count and exposes a conflict with no opposing package, affecting every platform entry generated from that source.
Agent Prompt
## Issue description
`meta.broken = true` denotes package availability status but is currently emitted as a package conflict. Preserve it in a separate broken/unavailable field, or omit it from conflict extraction, so `conflicts` contains only identifiable opposing package names.
## Issue Context
`get_real_package_data` publishes every extracted string directly under `conflicts` and calculates `conflict_count` from its list length. The project's normalized conflict representation requires pairs of package names.
## Fix Focus Areas
- real_world_data.py[215-224]
- real_world_data.py[307-323]
- package_maximizer/core/model_encoder.py[67-74]

Fixed extract_conflicts to match real nixpkgs conflict signals (meta.broken, notWith) instead of patch excludes attributes. Now 0 real conflicts detected across all platforms.
