Release Notes

Added

• A plat body now records the seed it ran under (FetchPage.seed,
  default 0), an ordinary field covered by plat_hash, so a run is
  self-describingly reproducible (HESO/1.0 §4).
• heso-verify: a standalone HESO/1.0 Grade-0 verifier crate that owns
  the canonicalization, plat_hash, and sealed-envelope open/verify
  logic with a minimal dependency set (serde, serde_json, serde_jcs,
  blake3, ed25519-dalek verify-only, base64) — no engine, DOM, or
  network crate. The engine's verify path now delegates to it, so the
  open/verify logic lives in exactly one place. The verb surface
  (heso unseal / heso verify) is unchanged.

Changed

• heso run replays under the seed recorded in the input plat rather
  than a hardcoded 0, so a deterministic replay reproduces the same DOM
  an independent verifier would. An explicit --seed still overrides;
  legacy plats with no recorded seed fall back to 0. Replaying an
  unmodified plat stays byte-identical (the stamp → run plat_hash
  contract holds).

Fixed

• The PyPI wheel builds again. setup.py hands the native heso binary
  to setuptools as a scripts entry; setuptools' build_scripts
  command tried to tokenize it as Python and failed the wheel build
  (source code cannot contain null bytes on Linux, invalid or missing encoding declaration on Windows). The binary is now copied
  into the wheel's *.data/scripts/ directory verbatim. 0.1.8 shipped
  to npm but not PyPI for this reason; 0.1.9 restores PyPI.
