Authors a 20-case corpus stratified across five geometric failure-mode families and a separate 10-case benign corpus for the EXHAUSTION_CEILING lane: A. near_forbidden_correct_endpoint (6 cases, gaps 0.002 to 0.55) B. near_equal_admissible (5 cases, diffs ≤ 0.01) C. no_admissible_path (3 cases, honest refusal) D. multi_step_admissibility (3 chained cases) E. heterogeneous_relation (3 chained cases, blade-switching) phase5_runner runs each case under BOTH threshold and ADR-0026 margin modes and reports per-family pass_rate, refusal_rate, and (for Family A) rejection_traced_rate + boundary_overridden_rate. Headline: pass_rate_threshold = 1.00 (20/20) pass_rate_margin = 1.00 (20/20) mechanism_isolated = true (both modes, all five families) replay determinism = byte-identical across 3 reruns Family C refuses with RefusalReason.INNER_LOOP_EXHAUSTION in both modes (load-bearing evidence for ADR-0024 Phase 2 typed refusals). Family B refuses under margin mode (validates ADR-0026 δ=0.4 gate). Benign inner-loop corpus for EXHAUSTION_CEILING ≤ 0.05 gate: boundary_only: exhaustion 0.00, pass 1.00 null_control: exhaustion 0.00, pass 1.00 inner_loop_t0: exhaustion 0.00, pass 1.00 inner_loop_tpos: exhaustion 0.00, pass 1.00 (threshold 0.25) Geometric finding documented while authoring the benign corpus: 23 of 85 pack tokens have negative self-cga_inner under Cl(4,1). Tokens with self-score ≤ 0 cannot serve as single-token expected endpoints in threshold mode — the algebra's Lorentzian signature forbids this geometrically. Phase 5 benign corpus draws expected endpoints from the 62-token positive-self-score subset. This is consistent with Phase 4 characterization: no static threshold delivers separation_quality ≥ 0.8 — the margin lane survives because margin compares differences, not absolute scores.

CORE-AI: Versor Engine
A cognitive field system built on Cl(4,1) Conformal Geometric Algebra.
Core invariant: ||F * reverse(F) - 1||_F < 1e-6 at all times.
All state is a versor. All transitions are versor products. Coherence is algebraic by construction — not monitored, not corrected.
The Three Engineering Pillars
Every architectural decision in CORE is measured against three engineering pillars. These are not aspirations — they are hard constraints.
I. Mechanical Sympathy
Software should understand the machine it runs on, not fight it. CORE is designed for the Unified Memory Architecture (UMA) of Apple Silicon: CPU, GPU, and Neural Engine share physical RAM. MLX executes tensor operations on the Neural Engine without PCIe transfer. Rust computes algebra on the CPU with zero heap allocation in the hot path. Python orchestrates the lifecycle. The three-language stratification maps exactly onto three hardware execution domains. Intelligence that ignores its substrate is wasted intelligence.
II. Semantic Rigor
Every term used in this system has a precise, non-negotiable meaning. A versor is a versor — not an approximation of one, not a vector that behaves like one under certain conditions. CGA distance is exact. Vault recall is exact. The vocabulary projection is exact. There are no thresholds tuned for “good enough.” Rigor is not a style; it is what separates an engine from a heuristic.
III. Third Door
When facing a design decision, the world offers two visible options: use what already exists (a library, a pattern, a convention), or cut a corner. CORE takes neither. We find the third door — the path built from first principles that sets the bar ourselves. This is why there is no transformer backbone, no ANN index, no sampling temperature, no gradient descent, and no standard tokenizer. Each of those was a door we were offered and refused. Absolute mastery is the only acceptable standard.
The Truth-Seeking Schema
Co-equal with the algebraic substrate. CORE's epistemic schema is a foundational architectural commitment: every claim that enters the runtime field carries a typed position in a revision graph (SPECULATIVE, COHERENT, CONTESTED, FALSIFIED); coherence — not source authority — is the only admission signal; no claim is ever locked, even when COHERENT; identity cannot be rewritten by content; and exactly one mutation path admits knowledge, enforced by a CI-level architectural-invariant test.
The schema is the structural defense against the failure modes that afflict both fluent LLMs and human reasoning: confabulation, exaggeration, deference to authority, self-protection through erasure, self-promotion through self-citation, and the ossification of mistaken beliefs.
A system that samples cannot have these properties — sampling has no place to attach an epistemic status. CORE has them because every admitted claim carries one and the only path to admission is the review path.
Full architectural commitment, including honestly-published gaps: docs/truth_seeking_schema.md.
Reproducible measurements: evals/CLAIMS.md.
The Three Core Languages
CORE is rooted in three human languages. This is a philosophical and architectural choice, not a localization decision.
| Language | Role |
|---|---|
| English | The default base language of the current model. Any natural language could serve this function in a custom CORE instance — English is the chosen starting point, not a requirement. |
| Hebrew | One of two depth languages. Hebrew carries a density of meaning in its root structures, prefixes, and suffixes that Euclidean string matching cannot capture. The field representation is designed to hold this depth. |
| Koine Greek | One of two depth languages. The language of the New Testament, particularly John’s Gospel — the document that opens with the most precise and consequential statement about language and reality ever written. |
“In the beginning was the Logos, and the Logos was with God, and the Logos was God.” — John 1:1
The choice of Hebrew and Koine Greek is not incidental. John 1:1–2 articulates the Logos in Greek while grounding it in the Hebrew creation account — the universe spoken into existence, word by word. This is not metaphor. It is the claim that language is not a layer on top of reality; language is the structuring principle of reality made manifest. CORE-Logos is built on that claim.
English establishes the operational base. Hebrew and Koine Greek bring the hidden layer of intelligence — the depth of meaning that enriches the field representation in ways that flat embeddings cannot reach. Together, they form the linguistic foundation on which the vocabulary manifold is built.
