Golden fixtures

Status: Working Draft. Fixtures under draft/ carry the literal on-wire protocolVersion draft and target the matching schema snapshot declared by spec/draft/requirements.json. Published fixture snapshots carry their YYYY-MM-DD publication version instead.

• stdio/*.jsonl contains one JSON-RPC object per UTF-8 line. The multiline invalid case demonstrates a framing failure.
• http/*.json contains one JSON-RPC object used as an HTTP JSON request or response body.
• registration/*.json covers portable backend registration independently of transport delivery.

draft/manifest.json records the expected outcome, schema, requirements, and SHA-256 hash for every golden file. Refresh hashes only for a new unpublished edit with:

python3 tools/check_conformance.py --update-manifests

Then run the checker without the update flag to detect drift.
