Anders Olsson	5e752f9e98	refactor(api): rename Batch to TimeSlice ... TimeSlice says what it is: every event sharing one timestamp. The History field .batches is renamed to .time_slices. Local variables named `batch` referring to TimeSlice instances are renamed to `time_slice`. Part of T2 of docs/superpowers/specs/2026-04-23-trueskill-engine-redesign-design.md.	2026-04-24 10:54:31 +02:00
Anders Olsson	cdfd75f846	bench: capture T1 final numbers and fix clippy warnings ... Fixed: - Removed unused .enumerate() in batch.rs - Removed unused agent::Agent import - Consolidated multiple bounds in generic parameters (lib.rs) - Suppressed dead_code for test-only code with #[allow(dead_code)] - Fixed unused imports and neg-multiply lint Batch::iteration: 27.023 µs (T0 was 21.253 µs, expected minor regression from T1 infrastructure). Gaussian::* unchanged (~236-280 ps). Acceptance: T1 factor-graph refactor lands without clippy/fmt issues. All 53 tests pass. Closes T1 tier.	2026-04-24 09:04:29 +02:00
Anders Olsson	8f60258dba	refactor(batch): replace HashMap<Index, Skill> with dense SkillStore ... SkillStore is a Vec<Skill>-backed dense store with a parallel present mask, indexed directly by Index.0. Eliminates per-iteration hashing in the within-slice convergence loop; O(1) array lookup replaces O(1) amortised hash lookup with better cache behaviour. Iteration order is now ascending-by-Index (was arbitrary for HashMap); EP fixed point is order-independent so posteriors are unchanged. Part of T0 engine redesign.	2026-04-24 07:08:20 +02:00
