From fbbe56e80d2fb20c51ea18ec93de6aa8d9901487 Mon Sep 17 00:00:00 2001 From: Ronald Tse Date: Wed, 7 Oct 2026 06:51:59 +0800 Subject: [PATCH] feat(ml): plane runtime + neural parity golden runner PlaneModel (K-pass mask-predict, per-char majority vote, byte-exact render, sha-verified zip contract) ported from the Python reference; cycling tiny-graph fixture (generated once via the py toolchain); env-gated golden e2e with the quantized-tolerance contract - int8 argmax tie-flips across onnxruntime builds are numeric, not logic (3/50 rows, 1-2 char diffs over 600-1000-char rows measured). --- lib/interscript/ml.rb | 3 +- lib/interscript/ml/plane.rb | 98 +++++++++++++++++++++++ spec/interscript/fixtures/tiny-plane.zip | Bin 0 -> 848 bytes spec/interscript/ml/golden_spec.rb | 48 +++++++++++ spec/interscript/ml/plane_spec.rb | 52 ++++++++++++ 5 files changed, 200 insertions(+), 1 deletion(-) create mode 100644 lib/interscript/ml/plane.rb create mode 100644 spec/interscript/fixtures/tiny-plane.zip create mode 100644 spec/interscript/ml/golden_spec.rb create mode 100644 spec/interscript/ml/plane_spec.rb diff --git a/lib/interscript/ml.rb b/lib/interscript/ml.rb index b19a8f4a..0288dad1 100644 --- a/lib/interscript/ml.rb +++ b/lib/interscript/ml.rb @@ -14,8 +14,9 @@ module Interscript::ML autoload :Model, "interscript/ml/model" autoload :Vocab, "interscript/ml/vocab" autoload :Byt5Onnx, "interscript/ml/byt5_onnx" + autoload :PlaneModel, "interscript/ml/plane" - # Expected to be loaded before IMF/Byt5Onnx entry points. + # Expected to be loaded before IMF/Byt5Onnx/PlaneModel entry points. def self.require_optional!(gem_name, feature: gem_name) require feature rescue LoadError => e diff --git a/lib/interscript/ml/plane.rb b/lib/interscript/ml/plane.rb new file mode 100644 index 00000000..fe1f6283 --- /dev/null +++ b/lib/interscript/ml/plane.rb @@ -0,0 +1,98 @@ +# frozen_string_literal: true + +require 'tmpdir' +require 'json' + +module Interscript + module ML + # Plane-factorized runtime (kind=plane artifacts): one ONNX graph + # maps (input_ids, plane_ids) -> per-position class logits over the + # diacritic classes; decoding is K mask-predict passes feeding the + # argmax plane back.
