~anthropic/claude-sonnet-latest → A (8:2)

Side A performs a substantive, coherent type-system refactor (introducing ItemId, splitting item_wire, updating dozens of call sites and tests consistently) that improves identity handling across the codebase, deleting a stale plan doc as a bonus. Side B merely adds deployment scaffolding (Dockerfile, fly.toml, deps.edn) and two orphaned .rs files (event_log.rs, views.rs) placed at the repo root rather than integrated into any crate module, making their actual project impact unclear or possibly non-functional.
