Crate boundary_compiler 

boundary-compiler — RFC 8785 JCS with boundary profiles and duplicate-key rejection.

Overview

This crate implements RFC 8785 — JSON Canonicalization Scheme (JCS):

• Canonicalizer that serializes JSON into deterministic byte sequences
• Duplicate-key rejection (RFC 8785 mandates duplicate object keys are errors)
• blake3 Content-Digest of the JCS string
• Boundary profiles for dialect, schema ID+version, canonicalization profile, unknown-field policy, and resource ceilings
• JSON Schema validation (stub — always passes)

Integration

This crate is intended to replace semantic_memory::graph::canonical_json_string() with a standards-compliant JCS implementation.

Example

use boundary_compiler::{Canonicalizer, ContentDigest, BoundaryProfile};
use serde_json::json;

let c = Canonicalizer::new();
let val = json!({"b": 2, "a": 1});
let canonical = c.canonicalize(&val).unwrap();
assert_eq!(canonical, r#"{"a":1,"b":2}"#);

let digest = ContentDigest::compute(&val).unwrap();
println!("Digest: {}", digest);

Error handling

All fallible operations use thiserror errors — no unwrap() or expect() in production. Duplicate keys return JcsError::DuplicateKey, and schema validation failures return JcsError::SchemaValidation.
