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

B is a substantive, correctness-focused type refactor (CanonicalItemUrl -> ItemId) that touches the core reducer/ranking/RPC layers with real design tradeoffs (enum variants, parent/tilde logic, serde) and includes updated tests, representing durable architectural investment. A is mostly deploy/ops scaffolding (Dockerfile, fly.toml, CI) plus a UI/audit-feed feature layered on existing code—useful but more additive/operational than foundational, with much of the diff being CSS/JS glue rather than core logic changes.
