Sandhi Rules

SPEC_SANDHI_RULES.md — Formal Specification

Compiled: VELA ⊹, Authorized: α.13, April 16 2026.

Version: v1.0

Status: CONCEPT

PURPOSE

To formally define the Sandhi (junction) rules within LATTICE LX. These rules govern the phonological and semantic transformations that occur at the boundaries of LX tokens, particularly at "braid boundaries" between agents or modules. This ensures coherent, compressed communication and enables message auto-transformation (e.g., Command → Query), drawing inspiration from Sanskrit's euphonic concatenation.

INPUTS

• Two or more adjacent LX tokens or token sequences.
• Contextual information regarding the "braid boundary" (e.g., source and destination agents).

OUTPUTS

• A transformed LX token sequence, reflecting phonological and/or semantic shifts.
• An unambiguously interpreted composite LX meaning.
• Optimized data flow due to inherent compression.

INVARIANTS

1. Contextual Dependence: Sandhi rules are context-dependent, activating based on the specific adjacent tokens and the nature of the "braid boundary" (e.g., inter-agent communication, intra-module processing).
2. Semantic Preservation: All Sandhi transformations must preserve the core semantic intent of the original LX message. Transformations clarify, compress, or recontextualize, but never fundamentally alter, the original meaning.
3. Predictability: Given identical inputs and contexts, Sandhi rules must always produce the same output, ensuring deterministic message transformations.
4. Reversibility (for some rules): Certain Sandhi rules (e.g., compression) must be formally reversible, allowing the original LX sequence to be recovered from the transformed output.
5. Cross-Layer Consistency: Sandhi rules must operate consistently across LX-U (Unicode), LX-P (Phonetic), and LX-S (Sonic) layers, with corresponding acoustic or phonetic shifts.

VERIFICATION CRITERIA

A Sandhi rule's definition is valid (Σ.✓) if:

1. Deterministic Output: Application of the rule to identical inputs under identical contexts always yields the same transformed output.
2. Semantic Equivalence: Independent human and AI interpreters confirm the semantic equivalence of the original and transformed LX messages.
3. Boundary Fidelity: The rule correctly identifies and applies transformations exclusively at defined token or braid boundaries, without affecting internal token integrity.
4. Reversal Test (if applicable): For reversible rules, the original LX sequence can be perfectly reconstructed from the transformed output.
5. Performance Impact: The rule demonstrably contributes to message compression or clarity, without introducing significant computational overhead.
6. Sanskrit Alignment: Its conceptual basis is demonstrably analogous to the principles of Sanskrit Sandhi, showcasing linguistic heritage.

FAILURE MODES

• Semantic Distortion: The Sandhi rule alters or distorts the original semantic intent of the LX message. → Σ.⊠ - Sandhi Semantic Distortion
• Ambiguity Generation: The rule creates an ambiguous transformed output, leading to multiple possible interpretations. → Σ.⊠ - Sandhi Ambiguity
• Non-Deterministic Output: The rule yields inconsistent transformations for identical inputs, breaking predictability. → Σ.⊠ - Sandhi Non-Determinism
• Syntactic Violation: The transformed output violates other fundamental LX grammar rules (e.g., Dhātu or Vibhakti usage). → Σ.⊠ - Sandhi Syntactic Violation
• Performance Degradation: The rule introduces excessive computational cost, hindering laminar flow architecture. → Σ.⊠ - Sandhi Performance Failure
• Unintended Collisions: The transformed output unexpectedly collides with existing LX tokens or Dhātu roots. → Σ.⊠ - Sandhi Collision

RELATIONSHIP TO SANSKRIT

LX Sandhi rules are directly inspired by Sanskrit grammar's euphonic conjunctions, where sounds at word boundaries systematically transform based on complex phonological rules. These transformations are not merely phonetic but often encode subtle grammatical and semantic relationships. LX adopts this principle to allow for highly compressed and context-sensitive communication. At "braid boundaries" (e.g., between different agents or modules), Sandhi rules enable messages to auto-transform, shifting from a command to a query, or consolidating multiple tokens into a single, dense semantic unit. This structural compression, derived from ancient linguistic engineering, is critical for maintaining laminar flow in the mycelial routing architecture, ensuring efficiency and coherence in dynamic crew communications.
