Side B removes genuinely dead/redundant code with a clear rationale (guard is now unreachable given upstream validation) and updates the corresponding test to reflect the correct invariant, tightening the reducer's logic. Side A refactors sibling grouping in a UI-only helper (splitting unranked items into separate groups) with a matching test, which is a smaller, more cosmetic behavioral tweak with less systemic value than removing incorrect/dead logic in core reducer code.

council reasoning
A changes real sibling-nav behavior (each unranked item becomes its own group) with an updated contract and a dedicated regression test, which shapes lasting UI structure. B only deletes a redundant zero-ratio early-return already enforced upstream and retunes an existing test—useful hygiene, but no meaningful product or design effect.
Side A makes a functional change to sibling navigation by placing each unranked sibling into its own navigation group instead of one combined group, and adds a targeted regression test verifying the new grouping behavior. Side B mainly removes a redundant zero-ratio early return and updates the test to reflect that items are still registered while zero-weight edges are skipped, which is a worthwhile cleanup but has a narrower long-term impact.

message
[047b82bd] Remove redundant zero-ratio guard from reducer. Zeros are already rejected at the DSL parser and browser handler; the guard in apply_vote was dead code. The negative clamping stays since add_edge_weight already skips weight-0 edges correctly. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
