//! `wave49_full_stack` — JouleClaw + Sandbox + Joule-Code, composed.
//!
//! Simulates one trace going through all three open standards:
//!
//! 1. **JouleClaw cascade** — a free-form request walks the
//!    `JouleClawStack::with_defaults` runtime. We capture the joules,
//!    tier, and energy provenance, then mint a JCR-1 receipt.
//!
//! 2. **Sandbox attestation** — the same workload "ran inside" an
//!    S5 sandbox unit with Cpu+Gpu grants. We emit the canonical
//!    wire shape `sandbox-rs` produces (JCS-canonical JSON +
//!    Ed25519 signature) without depending on the sandbox-rs source
//!    — the integration claim is at the WIRE LAYER, per JouleClaw
//!    doctrine.
//!
//! 3. **Joule-Code coding-op cargo** — the workload was a coding
//!    operation. We emit the canonical `joule-code` wire shape
//!    (BLAKE3-CBOR `op_id`, Ed25519 author signature) the same way.
//!
//! 4. **Cross-binding** — `CrossStandardBinding` records the three
//!    reference ids per the shared `trace_id` and runs the
//!    [`InvariantVerifier`] against them:
//!    - trace-id equality across the three
//!    - joules within tolerance (cascade ≈ sandbox)
//!    - declared provenance == worst observed across standards
//!    - all stewards (binding + cascade + sandbox supervisor) in
//!      the trusted set
//!    - sandbox device grants ⊆ cascade-authorised device classes
//!
//! 5. **Three artifacts written to /tmp/** with the binding doc as
//!    the load-bearing fifth. An auditor verifies any single
//!    standard's receipt independently AND can run the binding
//!    verifier to assert the cross-standard invariants.
//!
//! Run:
//!     cargo run -p jouleclaw-stack --example wave49_full_stack
