SDK and error contracts

Wisent Errors

Stable, cross-runtime error envelopes and integration contracts.

Wisent Errors defines one stable envelope, catalogue, severity model, retry contract, and boundary behavior across JavaScript, Python, Rust, and Swift.

Quick start — Create and inspect the first envelope.
Catalogue — Stable codes and meanings.
Conformance — Validate runtime implementations.
Integration — Adopt errors at system boundaries.
Runbook — Diagnose and operate failures.
