What

The neural-layer ledger gains the two Arabic 2.0 rungs:

  • ara-diac-2.0 (server tier): DER 2.2864 full-set windowed zero-skip — the new canonical teacher (news-domain sweep over 1.0: ID −0.29pp, OOD WikiNews-2024 multi-ref 17.3794/11.8273 vs 19.82/12.46). Best dedicated model on SadeedDiac-25 under the protocol.
  • ara-diac-small-2.0 (client tier): DER 4.8218 — a 42% error reduction over the 1.0 (8.259) at identical architecture and artifact size: r7 teacher labels + the Muon optimizer, pre-registered as E4 (gate ≤6.26, prediction 4.3–5.0).

Status "releasing" — artifacts gated and publishing via the release pipeline.

ara-diac-2.0 (teacher): DER 2.2864 full-set windowed zero-skip; OOD
WikiNews-2024 multi-ref WER 17.3794/DER 11.8273 — full sweep over 1.0.
ara-diac-small-2.0 (client): DER 4.8218 — a 42% error reduction over
the 1.0 at identical architecture and artifact size (r7 teacher labels
+ Muon optimizer; pre-registered E4).
