-Chronos-EntropyDepth
+# Chronos Certificates
 
-Information-theoretic limits on refinement and computation.
-Entropy-Depth bounds, structural obstructions, and executable artifacts.
-
-Overview
-
-Chronos-EntropyDepth is a core research repository within the Unified Rigidity Framework (URF).
-It formalizes and studies Entropy-Depth as a universal obstruction to fast computation under locality, bounded information flow, and admissible refinement processes.
-
-The repository contains definitions, constructions, and executable artifacts supporting lower bounds on sequential refinement depth, with applications to SAT, locality-restricted algorithms, and capacity-limited computation.
-
-This repository is intended to be:
-
-Audit-ready
-Reproducible
-Structurally minimal
-Consistent with URF admissibility standards
-Core Concept: Entropy-Depth
-
-Entropy-Depth (ED) measures the minimum sequential depth required for any admissible process to resolve a system with initial entropy ( H(X) ), under bounded per-step information gain.
-
-Informally:
-
-Local or bounded-width computation can only extract a constant (or polylogarithmic) amount of information per step.
-High-entropy instances therefore force long sequential depth.
-ED lower bounds translate into intrinsic time lower bounds for large classes of algorithms.
-Chronos is the structural program establishing, amplifying, and certifying these bounds.
-
-Scope of This Repository
-
-This repository focuses specifically on:
-
-Formal definitions of Entropy-Depth
-Chronos amplification mechanisms
-Locality-based obstructions (FOᵏ, WLᵏ, bounded-radius refinement)
-Certified negative results for shallow refinement
-Executable witnesses and verifier-friendly artifacts
-It does not attempt to:
-
-Solve P vs NP outright
-Enumerate all SAT algorithms
-Replace general complexity-theoretic models
-Instead, it isolates structural limits shared by broad algorithmic classes.

+This repository is intentionally **certificate-only**. As of tag `chronos-certificates-frozen`, the Chronos depth constants and related artifacts are frozen, cryptographically signed, and treated as canonical. The files `chronos_constants.json` and `Chronos/Cert/ChronosDepthConstants.lean`, together with their corresponding `.minisig` signatures, constitute the complete, verifiable Chronos certificate set. No Chronos theory is developed here: all mathematical definitions, transport lemmas (including the PSH → boundary-overlap conditional), and proofs live upstream in `urf-core`. Any modification to the frozen artifacts requires an explicit unfreeze decision, regeneration of signatures, and a new freeze tag.
