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

Side B removes a ~1700-line over-engineered, unreliable keystroke-transition parser and replaces it with a small, robust paste-and-go URL parser plus matching tests, deleting significant dead complexity (parser_action.rs, race-condition JS/tests) while keeping functionality working and well-tested. Side A adds a legitimate, moderate-scope feature (pool-scoped voting) with clean threading through several files, but it's a smaller, more incremental improvement compared to B's substantial simplification and removal of fragile, hard-to-maintain code.

~x-ai/grok-latest · winner B · 2:3 · permalink

B replaces an unreliable ~1.8k-line keystroke graph (plus parser_action, race mitigation JS, and Playwright race test) with a small, correct paste-and-go URL parser and redirect—lasting design cleanup that removes real failure modes. A is a solid, focused product feature (pool-scoped pair pick/nav and UI affordance), but it extends an existing path rather than retiring a broken subsystem.

openai/gpt-chat-latest · winner A · 5:2 · permalink

Side A adds a substantial new capability: pool-scoped voting, including new `/vote?pool=` behavior, pair selection constrained to child items, UI entry points, propagation of pool context through vote submission, and navigation updates. Side B simplifies the Reddit navigation flow by replacing a complex autocomplete parser with paste-and-go URL parsing and redirects, but it mainly removes existing functionality and UI complexity rather than adding comparable long-term project capability.

A — c_c6f5afec1d36 (tommy-mor)

message

[5350388a] Add pool-scoped voting: /vote?pool=<parent> picks pairs from children.

- /vote now accepts an optional `pool` param (parent item path). When
  provided without left/right, it picks the first unvoted pair from the
  pool's children. When provided alongside left/right, it constrains
  "next pair" navigation to siblings within the pool.
- "vote on children" button appears on item pages with ≥2 children,
  linking to /vote?pool=<item>.
- Pool is threaded through VoteComparePost → success JS so in-page
  morph after voting keeps the pool context for next-pair navigation.
