 ### Added
-- **RabbitMQ transport** (`PikaTransport`, `amqp://`): durable queue, persistent
-  delivery, `basic_get` + manual ack, and the contract AMQP properties (`type`=URN,
-  `correlation_id`=trace_id, `x-schema-version`/`x-source-lang`/`x-attempts`).
-  Optional `[amqp]` extra (lazy `pika` import) — the core stays zero-dep.
 - `EnvelopeCodec.urn()` — resolve the URN (`job`, accepting `urn` as an alias).
 - `EnvelopeCodec.accepts()` — consumer-side envelope validation (rejects empty URN,
   unsupported `meta.schema_version`, blank `trace_id`, non-object `data`).
 - Shared **cross-SDK conformance suite** under `tests/conformance/` (vendored from
   the canonical `conformance/` set) plus a `test_conformance.py` runner.
