[None][chore] Add a code-filtered mypy check for tensorrt_llm and fix the errors it found - #20946
Add scripts/run_mypy_broad.sh and mypy_broad.toml, which run mypy over tensorrt_llm/ and report only syntax, import-not-found, name-defined, used-before-def and call-arg errors. Errors about tensorrt_llm.bindings and third-party libraries are filtered out. Add the type-check-broad pre-commit hook.
Fix the errors the check found:
binding_dtype_size used an undefined name.
wait_first_completed called set.pop(f); use discard.
Logger methods did not accept exc_info, which several callers pass.
SpecMetadata.maybe_capture_hidden_states now defaults residual to None.
Declare module-level names that mypy could not see.
Silence remaining false positives with targeted type: ignore comments.
Dev Engineer Review
The PR adds a filtered mypy check for tensorrt_llm/ and a type-check-broad pre-commit hook. The checker selects syntax, import-not-found, name-defined, used-before-def, and call-arg errors, while excluding configured third-party and unavailable-extension cases.
The PR also changes runtime behavior: binding_dtype_size calculates byte size from bits, wait_first_completed uses discard, logger methods accept exc_info, SpecMetadata.maybe_capture_hidden_states defaults residual to None, and BaseResourceManager.add_dummy_requests accepts keyword arguments. Verify these changes with focused regression tests. Test results were not supplied.

This change adds a broad mypy check for tensorrt_llm/, updates annotations and type-checking suppressions across the package, and changes several runtime APIs and behaviors.

Summary
Configure and run the broad check .pre-commit-config.yaml, mypy_broad.toml, scripts/run_mypy_broad.sh
Adds a pre-commit hook and mypy configuration. The runner filters selected diagnostics and reports any that remain.
This PR adds a mypy hook that currently fails pre-commit, and the check can miss real errors in files that import cutlass. It also suppresses two existing runtime bugs instead of fixing them: MiniCPM-V vision requests that raise TypeError, and the FP8 rowwise conversion that raises NameError. Fix the hook so it passes and stops hiding errors before merging.

The change fixes removal of a completed result, but the PR does not add or identify a regression test. Add a test with one already-completed GenerationResult and assert that wait_first_completed yields it without raising. The previous wait_set.pop(f) call would fail this test.

Limit the cutlass exclusion to CuTe DSL kernel paths.
The branch at lines 57-59 drops every selected diagnostic from any file that imports cutlass. This includes unrelated name-defined and call-arg errors. Mypy reports these errors in files such as tensorrt_llm/_torch/models/modeling_dspark.py and tensorrt_llm/_torch/cute_dsl_utils.py, and the check can pass while they remain. The script's stated reason, that mypy cannot see cutlass.Int32, produces attribute errors, which are not among the selected codes. Keep the exclusion for cute_dsl_kernels/ paths only. Handle any cutlass false positives in the remaining files with targeted # type: ignore comments.

Add the missing third-party names to THIRD_PARTY_LIBS.
THIRD_PARTY_LIBS does not include click, pydantic, aiohttp, uvicorn, msgspec, prometheus_client, strenum, or mpi4py. The runner therefore keeps their import-not-found errors. If those packages are not installed, the script prints the errors and exits 1, so the type-check-broad hook fails.
The dotted-name matching works as intended. TP_IMPORT_REGEX matches named "mpi4py.futures" when the root mpi4py is listed. The failure comes from the missing root names, not from the regex.

Pass the required max_seq_len argument.
A vision request reaches _get_image_features, which calls _make_attn_metadata. That method calls _prepare_qwen_vl_vision_attn_metadata without its required keyword-only max_seq_len, so the call can raise TypeError before metadata preparation. The type: ignore only hides the mypy error. Pass a configured positive bound that covers seq_lens and remove the suppression.
This call was already identical at the merge base; the PR only added the suppression, so the runtime defect is pre-existing.

Update the annotation in set_task_collections so the name-defined type-ignore
applies to the line where mypy reports the unresolved TaskCollection reference,
or replace the reference with a resolvable type.

Move the type-ignore to the reported annotation line.
Mypy reports Controller as undefined on Line 101. The ignore is on Line 102, so the error remains and the Release Checks pre-commit job fails.
Move the ignore to Line 101, or provide a resolvable type.

Align the factory type with the three-argument call.
If a caller supplies a two-argument factory, as allowed by the client_factory annotation on Line 53, setup() raises TypeError because both calls pass max_retries as a third argument. The factory in tensorrt_llm/commands/serve.py:2325-2332 accepts that argument, so update the declared callable type to match the factory contract and remove these suppressions.

Update the client_factory annotation to require the three arguments passed by
setup, including max_retries, and remove the type suppressions from both factory
calls.

Add scripts/run_mypy_broad.sh and mypy_broad.toml, which run mypy over tensorrt_llm/ and report only syntax, import-not-found, name-defined, used-before-def and call-arg errors. Errors about tensorrt_llm.bindings and third-party libraries are filtered out. Add the type-check-broad pre-commit hook.
Fix the errors the check found:
Dev Engineer Review
The PR adds a filtered mypy check for
tensorrt_llm/and atype-check-broadpre-commit hook. The checker selects syntax, import-not-found, name-defined, used-before-def, and call-arg errors, while excluding configured third-party and unavailable-extension cases.The PR also changes runtime behavior:
binding_dtype_sizecalculates byte size from bits,wait_first_completedusesdiscard, logger methods acceptexc_info,SpecMetadata.maybe_capture_hidden_statesdefaultsresidualtoNone, andBaseResourceManager.add_dummy_requestsaccepts keyword arguments. Verify these changes with focused regression tests. Test results were not supplied.QA Engineer Review
