⚡ Bolt: Avoid redundant O(N) ToDictionary allocation in AddReachabilityWarnings hot path#291
Conversation
…habilityWarnings Hoists the `network.Edges.ToDictionary` call outside of the nested `HasPermittedPath` verification loop. Previously, this dictionary was built on every path check iteration, resulting in O(P*C*E) overhead, which has now been reduced to a single O(E) pre-computation.

👋 Jules, reporting for duty! I'm here to lend a hand with this pull request. When you start a review, I'll add a 👀 emoji to each comment to let you know I've read it. I'll focus on feedback directed at me and will do my best to stay out of conversations between you and other bots or reviewers to keep the noise down. I'll push a commit with your requested changes shortly after. Please note there might be a delay between these steps, but rest assured I'm on the job!

💡 What: Extract$P$ producers and $C$ consumers. Previously, the dictionary was rebuilt on each path check, causing continuous $O(E)$ memory allocations and CPU overhead on a hot path $O(P \times C \times E)$ .$O(E)$ pre-allocation. Will yield measurable speedups for networks with a large number of nodes and edges validating reachability constraints.
ToDictionary()edge mapping allocation outside of the producer/consumer loop withinAddReachabilityWarnings.🎯 Why:
HasPermittedPathis executed repeatedly within nested LINQ.Any()queries iterating over📊 Impact: Reduces redundant dictionary allocations and CPU overhead to a single
🔬 Measurement: Full test suite executes successfully locally. Verified via unit and benchmark coverage maintaining current bounds.
