Purpose

LexPons computes a SHA-256 digest over the canonical JSON/XML output so downstream consumers can verify exactly what was transformed. That digest is step 0 in the Veroberg hash chain.

Computation model

1. Produce the canonical output for the selected format.
2. Serialize the payload in the format-specific deterministic form.
3. Compute the SHA-256 digest over the resulting byte stream.
4. Return the digest alongside the transform payload and related metadata.

Notes

Future revisions of the specification will describe canonical serialization, metadata inclusion rules, and signing strategies. The current site documents the hash as a public integrity anchor rather than a full signature scheme.
