Implement the reasoning consumer integration feed for todo2code and other decision engines. Converts validated data2dsl comparison bundles into structured factual payloads (ConsumerFactFeed and CLI feed-consumer) preserving complete cryptographic evidence provenance while strictly maintaining separation of concerns (data2dsl provides facts and deltas; todo2code performs reasoning and policy).
ConsumerFactFeed implemented in src/data2dsl_consumer.py.feed-consumer supported in src/data2dsl_cli.py.tests/test_consumer.py.data2dsl).Phase 4 completed: consumer fact feed module and CLI subcommand implemented, tested (13/13 tests pass), and verified against the deterministic governance gate.
