The single explicit, fail-closed f64→f32 down-cast at the certified lifecycle egress. serving_cast(psi_steady, certificate, verdict) -> ServingState in core/physics/cognitive_lifecycle.py: - Casts ONLY a state that validates as a finite 32-vector, matches its certificate psi_digest, and was verdict.admitted — an uncertified, refused, or digest-mismatched state is never served. - Precision-checks the f32 result (cast_error = max|f64-f32|, unit norm) and fails closed on an f32 precision cliff (f32_precision_insufficient) rather than serving a silently-degraded state. - Keeps f64 as the source of truth: psi_steady and the psi_digest content-address chain are untouched; ServingState carries provenance back (source_psi_digest, certificate_id, measured cast_error) for audit. f64 stays inside relaxation/eigendecomp — this is the one place f32 appears (ADR-0245 §2.2 mechanical sympathy). Satisfies both ADR-0244 §2.5 and ADR-0245 §2.2 (one contract, two ADRs). Measured on a real certified outcome: cast_error ~1.2e-8, unit_norm_f32 ~0.99999998. Off-serving (A-04 guard: chat.runtime never imports it). ADR-0245 status map + plan doc updated. [Verification]: smoke 176 passed; fast lane 11907 passed / 109 skipped (-n auto, not quarantine/slow); 10 targeted serving-cast tests passed. |

CORE Documentation Index
This is the central index for all documentation in the CORE project.
Canonical Root Documents
- Whitepaper.md - The CORE architectural and philosophical whitepaper.
- Yellowpaper.md - Technical specifications and mathematical formulation of the CORE engine.
- PROGRESS.md - High-level project progress tracking.
- specs/runtime_contracts.md - Critical invariants and bounds for the runtime execution flow.
Directories
Architecture & Design
- adr/ - Architecture Decision Records (ADRs). The canonical history of all ratified engineering choices.
- architecture/ - High-level architectural documents (e.g., pipelines, schemas).
- analysis/ - Deep dives and master plans for structural changes.
- specs/ - Detailed technical specifications and invariants.
Planning & Progress
- plans/ - Capability roadmaps and implementation plans.
- briefs/ - Project briefs and scoping documents for upcoming work.
- issues/ - Detailed issue analyses and technical reproductions (not standard trackers).
- audit/ - Audit reports and claims ledgers.
Operations & Usage
- examples/ - Usage examples and reference integrations.
- workbench/ - Documentation for the CORE workbench UI and related tooling.
- agents/ - Agent-specific operational guides.
Note regarding
agents/grok/: Operational guide for using Grok 4.3 + Grok Build with CORE. This is not architecture documentation.
Learning & Evaluation
- curriculum/ - Documentation on the teaching/learning order and knowledge progression.
- evals/ - Evaluation methodology and performance criteria documentation.
- benchmarks/ - Benchmark evidence and performance tracking logs.
Historical & Experimental
- sessions/ - Chronological session logs documenting the "decision trail" and intellectual history of major choices.
- handoffs/ - Legacy brief, audit, and investigation notes (historical; the formal HANDOFF mechanism is retired — see AGENTS.md for the current lightweight
session-break-summary-<DATETIME>.mdconvention). - research/ - Raw research notes and preliminary findings.
- lab/ - Experimental content (Warning: Not ratified; must not be referenced as authoritative in production PRs).
