LXKeys Platform 1.0.1 is a corrective production patch for the API Entries → Chronoscript review workflow. Drafts created from accepted API Entries now preserve the source record type, semantic Profile ID, Profile Version and semantic extension during ordinary review edits. Validation and finalization are blocked if that source binding is inconsistent. A mutable draft affected by the 1.0.0 form-save defect can be returned to DRAFT and saved under 1.0.1 to restore the source semantic binding with an audit event. The patch does not change the canonical schema, Chronoscript protocol, Registry Sequence model, canonicalization algorithm or finalized-record immutability. Publication of this note does not constitute release activation. Active software status, activation time and package SHA-256 are published separately by Release History after successful production activation.
