~anthropic/claude-sonnet-latest → A (7:3)

Side A is a focused, tested bugfix improving sibling nav grouping logic within the actual codebase, with a new test validating the change. Side B adds orphaned files (Dockerfile, fly.toml, deps.edn, event_log.rs, views.rs) sitting at the repo root outside any crate structure, with no integration, no tests, and no indication they are wired into the build—suggesting stray/unintegrated scaffolding rather than lasting value.
