Side A is a small, precise cleanup that removes genuinely dead code, correctly reasons about why the guard is redundant, and updates the corresponding test to verify actual behavior—clear, verifiable, lasting value. Side B ('more seed') dumps loose files (Dockerfile, fly.toml, deps.edn, and stray event_log.rs/views.rs at repo root, not integrated into any module tree) with no clear integration or intent, appearing to be unstructured scaffolding rather than a coherent, reviewed contribution.

council reasoning
B adds lasting project infrastructure (Dockerfile, fly.toml deploy config, event_log persistence, and ViewStore), while A only deletes a small dead zero-ratio guard and retunes one test. The deploy/persistence modules outweigh a few lines of redundant validation cleanup.
Side A makes a targeted behavioral cleanup by removing a redundant zero-ratio early return that is already enforced by earlier validation, preserving negative clamping and updating the test to reflect the intended semantics (items and pairs are still registered while zero-weight edges are skipped). Side B adds several new files (Dockerfile, Fly config, event log and view store modules), but the patch shows no integration with the existing codebase, so much of its lasting impact is uncertain from the diff alone.

A — c_cf0a514b261a (tommy-mor)
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>
