ara-diac-plane-large-1.0

ara-diac-plane-large-1.0 — plane-factorized large encoder (dedicated #2)

The ByT5-LARGE plane variant: encoder-only plane factorization over 54
haraqat classes with K=2 mask-predict decoding, from rababa run-019 at
2 epochs (551k unique units).

Full-set SadeedDiac-25 (1,200 paragraphs, zero skipped, greedy):

• Total DER 2.7397 / Morph 1.6717 / Total WER 8.6083
• Dedicated podium: ara-diac-2.0 (teacher) 2.2864 > this model 2.7397 >
  plane-large 1-epoch 3.0078 > Gemini-Flash 3.1926
• Best dedicated system that still runs as one self-contained int8 ONNX
  graph (866 MB) with parallel K-pass decoding (no KV cache)

Provenance: run-019 epoch-2 final weights, exported on Modal from the
volume-native checkpoint (transit-tearing workaround); ONNX int8 sha256
f9cdba7448ddf32bfa3c50e5076dd9a8319d7b0ada01ecda6da2620e43abf428.
Process note: the epoch-2 number above is the corrected measurement
(the first E2 eval re-scored epoch-1 predictions; see docs/RESULTS.md).
