B is a small, focused correctness fix (enforcing valid vote ratio bounds across DSL parser, UI handler, and reducer) with targeted regression tests and a real behavioral improvement preventing degenerate/invalid votes. A is a large mechanical refactor moving code into a new types module with newtypes wrapping strings, which improves type-safety/organization but is mostly churn (renames, re-exports, moved tests) without fixing any bug or changing runtime behavior, and risks regressions across many call sites for marginal clarity gains.

council reasoning
B enforces a real ranking invariant (both ratio sides ≥ 1 and ≤ 100) in the DSL parser, UI POST path, and reducer (dropping zero-side votes instead of normalizing 0:0→1:1), with unit and integration regression tests. A mostly relocates existing canonicalize/path helpers into slug-types and wraps API strings in GardenItemUrl/ForumThreadUrl/TildeOntologyPath—useful structure, but largely mechanical re-export and call-site rewiring without fixing domain behavior. A precise multi-layer correctness fix outlasts diffuse type centralization alone.
Side A performs a substantial architectural refactor by moving canonicalization, path identity, and room-aware URL generation into shared `slug_types::paths` newtypes (`GardenItemUrl`, `ForumThreadUrl`, `TildeOntologyPath`) and updating API/RPC types to use those abstractions instead of ad hoc string helpers. Side B is a valuable correctness fix that consistently enforces vote ratio bounds (both sides 1–100) across the parser, UI, reducer, and tests, but its scope is a targeted validation improvement rather than a foundational API and type-system redesign.

[a888d56c] refactor: centralize path identity in slug-types Move canonicalization and CanonicalItemUrl into types::paths with GardenItemUrl, ForumThreadUrl, and TildeOntologyPath for JSON hrefs. Server canonical_path and path_types re-export slug-types; RPC and validation build hrefs via those types instead of string helpers. Made-with: Cursor

[aa0b175c] Enforce vote ratio constraints: both sides ≥ 1, max 100. Zero on either side produces no valid graph edge; ratios above 100 add no meaningful signal. Enforce in the DSL parser, browser POST handler, and reducer guard. Update browser pool test to use 99:1 instead of 100:0. Add unit and integration regression tests.
