~anthropic/claude-sonnet-latest → B (6:4)

Both are substantial, but B fixes a real correctness/design issue (persisting full Reddit API payloads via the event log for replay instead of only a derived view, removing implicit auto-fetch on navigation, adding configurable API bases and dotenv support) plus includes an integration test with a mock server and fixtures. A adds a reasonable new `/ui` dispatch abstraction and form-template mechanism, but it's mostly plumbing/refactor without new tested behavior or bugfixes, and its own tests are limited to unit-level template parsing rather than end-to-end verification.
