[Unreleased]

[1.0.1] — 2026-04-10

Fixed

  • R5 float normalisation (BRANCH-GENOME-002 follow-through): canonical_json now correctly normalises float values before serialisation. Previously 1.0 was emitted as 1.0; it is now emitted as 1. This closes the cross-language hash divergence between the Python kernel and any TypeScript or JavaScript implementation that applies R5 correctly (e.g. the bundled standalone_verify.py). Records containing float values produced under v1.0.0 will not verify against v1.0.1 — no such records exist because no AIEP-VECTORS fixture contained floats.
  • _nfc_object replaced by _norm_object which applies both R3 (NFC) and R5 (number normalisation) in a single recursive pass.
  • Non-finite numbers (NaN, Infinity) now raise ValueError explicitly rather than propagating through json.dumps.
  • KERNEL_VERSION incremented to 1.0.1. GENOME_LOCKFILE.json updated to LOCKFILE_VERSION 1.0.1 with new kernel_bundle_hash and kernel/canon/canon.py hash.

Migration

Any record committed with KERNEL_VERSION 1.0.0 that contains float values in its evidence or reasoning ledger will produce a different pack_hash under v1.0.1. No such records are known to exist. Records containing only strings and integers are unaffected.
