Closes the last open Rust parity gate from ADR-0020. Kernel: new versor_apply_closed_f64 in core-rs/src/versor.rs performs the full sandwich V·F·rev(V) + closure in f64, mirroring Python's algebra.versor.versor_apply + _close_applied_versor exactly: - no null-vector early branch (Python doesn't have one) - unitize_versor with dense-support seed fallback gate - post-unitize versor_condition < 1e-6 recheck - seed_to_rotor on failure, passthrough as last resort PyO3 binding: versor_apply_with_closure_f64 accepts/returns float64 arrays through new extract_f64_slice / f64_array_to_numpy helpers. algebra/backend.py::versor_apply routes through it under CORE_BACKEND=rust. Parity gate re-enabled (was skipped pending this port). 8/8 bit- identical across normalized hot-path + identity-versor cases. Bench (5000 iters, runtime hot path): python: 213.0 us/call rust: 7.4 us/call → 28.8x speedup All lanes green: algebra 132 (was 124+8skip), smoke 54, runtime 19, cognition 57, teaching 17, packs 6. Cognition eval 100% across all metrics. PROGRESS.md updated: versor_apply marked passing; Phase 5 Rust parity track now 5/5 surfaces gated and enabled. |

Architecture Decision Records
This directory contains the Architecture Decision Records (ADRs) for the CORE project.
ADRs record significant architectural decisions: what was decided, why, what alternatives were considered, and what consequences follow. They are permanent records — superseded ADRs are archived, not deleted.

Session Logs
Session logs record the decisions and rationale from individual working sessions. They are not ADRs — they are the narrative record that informed the ADRs.
