fix(discovery): stop a Qwen3-VL worker from serving video with another worker's contract - #14624
Conversation
Two vLLM replicas of the same Qwen3-VL model whose engine-level --mm-processor-kwargs differ produce the same mdcsum(), because the function hashes only one runtime_config key. They join one cohort, the group builds its single video-routing processor from one representative card, and that processor then governs requests served by a replica that never published vllm_qwen_video_processor_contract at all. mdcsum() now absorbs the canonicalized content of that key when the card carries it. Content rather than presence, because the worker derives the contract from its installed Transformers and vLLM packages and two workers can publish different contracts. Raw JSON rather than the typed contract, because the typed form lives behind the optional mm-routing feature and mdcsum() also names the on-disk model cache directory. canonicalize_json moves from discovery::watcher to utils so both hashing paths share one copy; serde_json runs with preserve_order here, so key order would otherwise split a WorkerSet on its own. Divergent replicas now produce different fingerprints, which reconcile_group turns into GroupStatus::Conflict. Cards that do not carry this key keep a byte-identical checksum.

Please address the rolling-upgrade compatibility issue. Two minor test comments are included below.
The Qwen video prompt-expansion contract is a per-WorkerSet routing input, not part of a worker's identity. Keep it out of `mdcsum()` so workers that publish different contracts, or none at all, still share one cohort, and resolve it across the cohort in the discovery controller instead: the group builds with the contract every member published, or with none when they disagree, which leaves exact video routing off while text serving continues.

One correctness issue remains in contract validation while a replacement build is pending.
A retained pipeline keeps expanding video prompts with the contract it was built from, but the group status carries the replacement's fingerprint while the rebuild is pending. A worker that republished a different contract without moving that fingerprint therefore kept serving against the contract it dropped. Bind the contract to the retained pipeline and revalidate it on every worker update, not only when the fingerprint changes. Signed-off-by: svc-glamr@nvidia.com <svc-glamr@nvidia.com>

factory: Addressed the [P1] review finding on The finding reproduced exactly as described. With The fix binds the retained contract to the retained pipeline rather than reading it back out of the group status, which carries the replacement's fingerprint while a rebuild is pending:
Coverage added for both cases the finding named, each failing before the change and passing after:
Checks run: The workspace check covers the whole tree because the change alters a struct field used across the discovery controller. |

Validate it first, and for remote references materialize it locally before the generator sees it, so the generator is always handed a trusted local path. This brings the sglang diffusion path in line with the vLLM/omni and trtllm backends, which already validate the same field. Behavior change: local I2I/I2V references now require DYN_MM_LOCAL_PATH to be set to the allowed directory; previously any path was accepted. common/http: - validate_media_reference() returns a plain filesystem path for local references; local_media_reference() is an async context manager that fetches a remote one through fetch_bytes(policy=...), which revalidates every redirect hop, into a temp file removed on exit. data: is rejected -- a URI is not a path. - fetch_bytes() gained max_bytes, streaming through collect_capped at an explicit read granularity so the cap is an allocation bound and not only a rejection: a 128 MiB-decoded gzip body against the 64 MiB cap peaks at 68,032,217 bytes rather than the whole decompressed body. Content-Length is caller-controlled and absent when chunked, and aiohttp's read(n) returns at most n bytes, so neither a header check nor a single capped read suffices. Defaults to None, leaving existing callers unchanged. - DYN_MM_MAX_FILE_SIZE_MB makes that cap operator-tunable, in megabytes, as the SGLang arg it replaces was. Read per call; empty, unparseable or non-positive falls back to 64 with a warning, so a malformed value neither takes the worker down nor reads as unlimited. - Messages built from caller input are bounded via describe_media_source, moved from multimodal/media_source.py (it pulls in torch) into url_validator.py and re-exported from its old home; a no-op below 120 characters. - HttpStatusError bounds its .message attribute, not only the rendered string: errors.rs::extract_http_like_error reads .status and .message off this class by name and forwards .message on a 4xx without calling str(). Backend exception text is bounded head-and-tail, since aiohttp renders the host before the errno. - validate_local_path uses exc.strerror rather than the raw OSError, whose text repeats the filename, and now catches the ValueError that Path.resolve() raises on an embedded NUL so callers keep their 4xx-vs-5xx decision. Rebased onto ai-dynamo#14563 (single aiohttp backend); the httpx-side half of the max_bytes plumbing went with that backend.

Adds only a comment to container/templates/vllm_runtime.Dockerfile, which matches the `vllm` path filter (container/templates/vllm_*) and so makes changed-files set vllm=true, which is what gates build-xpu and the heterog-test-px-dn / heterog-test-pn-dx jobs. What this exercises: - .github/workflows/pr-xpu.yaml (push to pull-request/[0-9]+, needs the xpu label) - .github/workflows/pr-xpu-heterogeneous.yaml (push; its guard deliberately skips the label gate) - .github/workflows/epd-test-template.yml (workflow_call, from the heterog jobs) - .github/scripts/test-filters.js (the brace fix from #22) - container/templates/vllm_runtime.Dockerfile rendered and built for device=xpu Not exercised: .github/workflows/xpu-heterogeneous-dispatch.yaml is workflow_dispatch only and has to be run by hand from the Actions tab. The marker comment must be removed before this branch is ever merged.

Every datatype was wrong, so spec-conforming clients cannot parse any tensor the RPC describes. Adds `oip_name()` next to `tensor::DataType::to_kserve` covering all fifteen proto variants (incl.

Run one vLLM worker per GPU node, use stable Grove ordinals for cache-owner slots, and request GPU-local RDMA resources for engines and Guard services. Provide a deployment helper for rendering and selecting either variant. Run the KV state agent alongside vLLM for process-local host memory. In memory-service mode, keep KVCR and the state agent in a separate container so its Guard and shared-memory pool survive engine restarts. Document that restarting the services sidecar invalidates the MVP recovery contract and requires deployment-level replacement. Add manifest coverage and an opt-in two-host lifecycle test. Kill the source EngineCore, hold it offline, and verify that the promoted Guard serves its preserved cache to the surviving target. Correlate response equality and KVCR transfer metrics with transmit and receive counters from the selected active HCA to prove RDMA transport.

.github/workflows/pr-xpu-heterogeneous.yaml; pin GPU_TAG to latest * .github/workflows/; add post-merge and nightly XPU heterogeneous CI Extract the XPU heterogeneous P/D pipeline out of pr-xpu-heterogeneous.yaml into xpu-heterogeneous-run.yml, a workflow_call reusable workflow, and call it from three thin trigger workflows so all three merge phases run the identical pipeline instead of drifting copies. xpu-heterogeneous-run.yml new, reusable. guard, changed-files, build-xpu, build-nvidia, resolve-images and both heterog tests, unchanged, plus 7 inputs. pr-xpu-heterogeneous.yaml reduced to the pre-merge trigger, the slash-command gate and the reaction. post-merge-xpu-heterogeneous.yaml new. push to main. nightly-xpu-heterogeneous.yaml new file, but the cron is MOVED, not added: it is the 0 23 * * * schedule that was already in pr-xpu-heterogeneous.yaml. No behaviour change per phase. force_all_tests replaces the old github.event_name == 'schedule' || github.event_name == 'issue_comment' expression with the same truth table: pre-merge passes github.event_name == 'issue_comment', nightly passes true. Post-merge also passes true, because a push to main has no PR base for .github/actions/changed-files to diff against, and post-merge exists to catch what per-PR gating missed. xpu-status-check stays a TOP-LEVEL job in each caller rather than moving into the reusable workflow. A job contributed by a reusable workflow reports to the Checks API as "run / xpu-status-check", so hosting it there would rename the context and leave any branch protection rule requiring xpu-status-check waiting forever on a check that no longer reports. The concurrency mapping stays byte-identical across all four workflows that touch this hardware, now including xpu-heterogeneous-dispatch.yaml. Three files do NOT get three slots: the cluster, the dynamo-system namespace and the onexpu-/onenvidia-rdma-kueue ResourceClaimTemplates are one global resource. The reusable workflow deliberately carries no concurrency block of its own, which would deadlock against the slot the caller's run already holds. Parameterised gpu_tag, model, tensor_parallel and runner as inputs so the callers can diverge; all default to the previously hardcoded values. Added workflow_dispatch to the nightly, without which a schedule-only workflow cannot be exercised before it reaches the default branch. Verified: all files parse; the four concurrency mappings are byte-identical; the reusable workflow declares no concurrency; every input each caller passes exists and every required input is supplied; nesting is depth 3 of the 4 GitHub allows. actionlint was not available to run, and will report queue:max as an unknown key in all four files, a known false positive. --------- Signed-off-by: Nikita

Summary
Qwen3-VL replicas can publish different video prompt-expansion contracts because their installed packages or engine flags differ. A WorkerSet uses one video-routing processor, so it must not use a contract that only some of its members publish.
Details
This change keeps
vllm_qwen_video_processor_contractout ofModelDeploymentCard::mdcsum(), preserving the existing checksum and allowing legacy workers and workers with different contracts to remain in the same cohort. Discovery canonicalizes and hashes the contract separately for each desired instance. The controller derives the cohort agreement and rebuilds the WorkerSet when that agreement changes. When the cohort has no unanimous contract, worker-set preparation removes the contract from the representative card so exact video routing is disabled while text serving and the other group behavior remain available.The controller now retains a committed WorkerSet while a membership-driven video-contract rebuild is queued, building, or retrying. The replacement takes over only after a successful commit; an in-place contract change on the already committed membership still withdraws the stale group.
Where should the reviewer start?
Start with
lib/llm/src/discovery/controller.rsfor cohort agreement and retained-pipeline validation, thenwatcher.rsandmodel_manager.rsfor preparation and replacement.lib/llm/src/model_card.rspreserves the Qwen/Nemotron checksum boundary.Related Issues
Validation
Current head:
a67101fe5dcc949a2c93afc3e9e186a6014f7331. The September 16, 2026 maintenance refresh confirms no merge conflicts, all 15 review threads resolved, and human approval fromjthomson04. CodeRabbit's commit status is successful.Pre Merge CI passed for this exact head, including Rust tests and Clippy. Full CI attempt 2 finished cancelled. The planner compliance retry and Dynamo runtime, vLLM, SGLang, and TensorRT-LLM checks passed, but frontend validation remains incomplete.
The frontend image retry exceeded its one-hour execution limit. Compilation had completed; the last build output showed license-file assembly. The backend status gate failed because that build was cancelled, and downstream frontend checks were skipped. Skipped checks are not passing validations.
Current
mainhas a similar frontend image timeout, where a 45-minute limit expired during image export. No compiler or test failure in these logs identifies a source repair. A targeted retry of the PR's new frontend job returned HTTP 403:Must have admin rights to Repository.A maintainer request asks for investigation of the image-build slowdown and a retry of that job and its dependents. Full CI is already authorized; no new authorization request is needed.Validation relies on remote CI. This maintenance pass made no source changes, commits, or pushes, and ran no local tests, builds, benchmarks, or new tests. No new review request is needed for the unchanged, approved head. Merge readiness is not established until frontend validation and the final status gate pass.
