Sovereign XML Compiler

Natural language → valid XML system prompts in one shot.

Ahmad Ali Parr · SnapKitty Collective · 2026

Zero correction iterations. Uses logit gating at the tokenization layer. The model physically cannot output invalid XML.


Three Operating Modes

1. GBNF Constrained Decoding

Grammar-based token masking at the softmax layer. For any token that violates the XML grammar: P(token | grammar) = 0. 100% valid XML in one pass. No retry loops.

2. Skeleton In-Filling

Model fills placeholder values only — never writes XML tags directly. The structure is fixed; only the content varies.

3. Dual-Pass Chain-of-XML

Stage 1: thought process generation. Stage 2: XML output with verified structure.


Gates Normalization Connection

The logit gating implements the Gates Normalization Constraint directly:

G_P(D_M) = softmax(logits_M + b_P)
b_P = -∞   for grammar violations

This is the structural enforcement of a constraint, not a filter on output. The simplex Δⁿ is navigated only over the valid token subset.
