Side A fixes a real concurrency bug (shared browser sentinel delegate blocking multi-user votes) with a coherent design change across server, CLI, types, and tests, including a new integration test proving the fix. Side B is a minor cosmetic HTML cleanup removing headers/labels with no functional change or test coverage, offering far less lasting value.

A fixes a real multi-user correctness bug by removing shared browser sentinel delegates (PendingSession.agent becomes Option, votes/posts use no delegate, authorship simplified) with integration coverage; B only deletes cosmetic forum chrome (compose heading/help text and thread subtitle/garden link).
Side A fixes a substantive correctness issue by removing shared browser sentinel delegates, changing pending sessions to use an optional delegate for browser logins, updating attribution logic, and adding integration tests that verify multiple human users can vote without erroneous shared AgentBound conflicts. Side B only makes minor UI cleanup by removing or relocating headings and help text in the compose view, with no evident behavioral improvement.

message
[b9476669] Remove browser sentinel delegates so multi-user votes work. Shared WEB_BROWSER_AGENT bound on first vote and blocked every later human; browser posts now use no delegate, matching forum UI. Co-authored-by: Cursor <cursoragent@cursor.com>
