Side A is a large mechanical refactor (splitting identity/canonical_path modules, changing wire formats) that mostly moves code around and changes conventions without fixing a functional bug, and even touches many call sites/tests for stylistic consistency. Side B is a small, precise bugfix that correctly reorders a guard to prevent ghost items and incorrectly-marked voted pairs in the ranking reducer, fixing a real correctness issue with a targeted, verifiable test update. Despite A's larger footprint, B delivers more durable, unambiguous value per line changed.

B fixes a real reducer correctness bug: zero-ratio votes used to run ensure_item and voted_pairs.insert before the early return, leaving ghost items and false voted pairs; the guard is moved before any side effects and the test now asserts empty index/edges/pairs. A is a large identity/path split and wire-format sweep (no @, optional delegate, module moves) that improves structure but is mostly reorganization and mechanical API/test churn relative to B’s lasting state-fix.
Side A introduces a lasting architectural separation by extracting path normalization into `canonical_path.rs` and identity parsing into `identity.rs`, removes identity rewriting from the reducer, standardizes stored/wire identities without `@`, makes delegate identities optional, and updates APIs, HTML, CLI, and tests to consistently enforce those semantics. Side B fixes a real reducer bug by moving the zero-ratio early return before `ensure_item` and `voted_pairs.insert`, preventing ghost items and false voted pairs, but it is a narrowly scoped correctness fix compared with Side A's broader, durable redesign.

message
[80ad7753] refactor: split canonical_path and identity; strict wire identity without @ - Add canonical_path.rs (tag + item URL normalization) and identity.rs (parse_username/parse_agent; reject @ in API input). - Slim events.rs to event types only; reducer applies no identity rewriting. - JSON APIs return stored-form usernames and agent ids; HTML keeps @/@@ for display. - Optional delegate on ingest; CLI and tests use naked uuid:rig:model.

[81de487b] Fix zero-ratio guard in reducer to drop before registering items or pair. Previously the early-return for zero-weight votes happened after ensure_item and voted_pairs.insert, leaving ghost items in the index and the pair incorrectly marked as voted. Move the check to before any side effects. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
