Feature: Publish canonical target-profile contract resources #158

Cohesive Capability

Edict publishes canonical, content-addressable contract artifacts for every Edict-owned resource slot required by edict.target-profile/v1: canonical CBOR rules, component sandbox requirements, fuel accounting, diagnostics ABI, and deterministic-execution policy.

These are authority artifacts, not illustrative prose identifiers. Runtime-owned target-profile generators can accept exact trusted bytes and expected digests instead of blessing arbitrary caller bytes under an Edict coordinate.

Cross-repo prerequisite for flyingrobots/echo#652.

Scope

• Define one authoritative byte artifact for each Edict-owned target-profile resource coordinate:
  • edict.canonical-cbor/v1
  • edict.wasm-component/v1
  • edict.fuel/v1
  • edict.diagnostics/v1
  • edict.determinism/v1
• Give every artifact an exact repository source, canonical encoding, stable coordinate, and reproducible SHA-256 digest.
• Publish executable checks that regenerate or verify all bytes and digests.
• State how provider generators receive trusted artifacts without registry lookup or mutable-name resolution.
• Add compatibility evidence showing a conforming target profile can bind the published resources.

Acceptance Criteria

• Repeated generation produces byte-identical artifacts and digests.
• Any semantic change moves the relevant digest.
• Wrong coordinate, bytes, digest, or provenance rejects before a target profile is emitted.
• The artifacts are runtime-neutral and contain no Echo-specific policy.
• Documentation distinguishes semantic contract resources from provider-owned lowerer/verifier component selection.

Boundaries

• No network registry, signatures, participant trust policy, or runtime execution.
• Do not embed a particular Echo lowerer or verifier.
• Do not make target-profile generators discover repository files implicitly.
