Side B fixes a real correctness/validation gap (rejecting invalid 0-sided and >100 vote ratios) consistently across parser, HTTP handler, and reducer, with matching test coverage, closing a genuine bug where 0:0 silently became 1:1. Side A is a mixed refactor that removes demo scaffolding (fine) but also introduces an async settlement-worker architecture with caching that changes vote-application semantics and concurrency behavior without clear justification or equivalent test rigor, making it riskier and less clearly a net positive.

council reasoning
A delivers lasting architecture: a settlement worker that batches votes, persists events, and recomputes ranking scores off the request path, plus read-only cached ranking and removal of the throwaway demo-counter path. B is a sound multi-layer validation fix (ratios ≥1 and ≤100 in DSL, UI, and reducer) with solid tests, but it is a narrower correctness guard than A’s design change.
Side A delivers a substantial architectural improvement: it removes the temporary demo counter feature, introduces a dedicated settlement worker that batches vote persistence and ranking recomputation, adds cached ranking reads (`ranked_items_cached`), warms the cache on startup, and switches HTTP paths from write locks to read locks for ranking display. Side B is a solid correctness change that consistently enforces vote ratio bounds (1–100) across the UI, DSL parser, reducer, and tests, but it is a narrower validation fix compared with A's broader, lasting simplification and performance-oriented redesign.

[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.
