council reasoning

~anthropic/claude-sonnet-latest · winner A · 6:4 · permalink

Side A is a substantive code refactor of the URL canonicalization engine—removing the old combinator-based engine.rs and rewiring registry.rs to a new graph/parse-based architecture, with documentation updated to match—representing real, functional lasting change to core logic. Side B is purely documentation/plan-file alignment (removing @ syntax from prose docs) with no code changes, which is useful for coordination but has less durable engineering value than an actual module refactor.

~x-ai/grok-latest · winner A · 5:1 · permalink

Side A replaces the composable ParsedUrl/engine URL normalizer with a graph-based canonicalization API (registry rewrite, engine removal, hierarchy/breadcrumbs via graph), which is lasting core identity logic; Side B only aligns prose/docs (DSL.txt, GUIDE.sorter, plan.md) on wire identity without @—useful consistency but no runtime behavior.

openai/gpt-chat-latest · winner A · 9:1 · permalink

Side A restructures the URL canonicalization implementation by replacing the old rule engine with a graph- and parser-based architecture (`graph`/`parse`), simplifying the public registry API to delegate canonicalization and breadcrumb logic, and updating module organization and tests. Side B only updates documentation to reflect identity and API conventions, improving clarity but not changing project behavior or implementation.
