Split the CI matrix from 2 jobs (sglang, vllm) to 4 by adding a test_type dimension (unit, integration). Each variant now provisions two separate GCP runners that execute in parallel, reducing overall wall-clock time. Key changes: - Add test_type matrix dimension to provision-runner, unit-tests, cleanup jobs - Add conditional steps: unit tests run only on test_type=unit, SFT+GRPO on integration - Update runner labels and instance names to include test_type for isolation
The tests sent application/octet-stream but the body was JSON-serialized data. FastAPI passed raw bytes instead of parsing JSON, causing 'bytes' object has no attribute 'nbytes' in rtensor._store_local. Key changes: - Change Content-Type from application/octet-stream to application/json - Clear _storage_stats in test fixture to prevent cross-test leaks

… model tests Add missing @torch.no_grad() to test_dcp_save_load_weights to prevent in-place param.zero_() error on grad-requiring leaf tensors, matching the existing decorator on test_hf_save_load_weights. Mock dist.get_rank in test_create_device_model_applies_use_kernels to handle the new rank check added by f34bea8 (memory_efficient_load meta device optimization) when distributed is not initialized.

Validate that raw_payload is a dict before unpacking into BatchShardRequest. Non-dict JSON bodies (e.g. arrays) raised TypeError instead of ValidationError, bypassing the 400 handler and falling through to the 500 catch-all.

Description
Split the CI matrix from 2 jobs (sglang, vllm) to 4 by adding a
test_typedimension (unit,integration) to the existingvariantmatrix. Each variant now provisions two separate GCP runners that execute in parallel, reducing overall wall-clock time for the CI pipeline.Fixed unit test bugs introduced by previous PRs.
