test(architecture): require support identity tests for semantic Tasks - #1402
Conversation
A family migrated to the semantic Task SDK must keep dependency-free checkpoint identity and default-task assertions in tests/test_support.py so the CPU premerge gate exercises them. Add an architecture check for every family whose runtime implements a semantic Task and backfill the 13 migrated timm families that only carried TensorRT-gated assertions.

An empty or unrelated tests/test_support.py satisfied the existence-only architecture check. Require the module to parse, assert its default_task, and resolve family identity through its own support module or resolve_family, and add a focused placeholder-rejection test.

Addressed in e7b6b1a: the guard now parses tests/test_support.py, requires an assert on default_task and identity resolution through the family's own support module or resolve_family, and a focused test rejects empty and unrelated placeholders. Re-ran the architecture tests (3 passed), the 13 support-test files (26 passed), Ruff, impact validation, and model CI validation. |
The Dev Community GPU lane failed before validation because the Brev instance could not provision: ResourceExhausted vpc.pool.count, instance state FAILURE.

Hi, the overall direction and the 13 family-owned support tests look good. There is one remaining issue before merge: _support_test_covers_identity() currently relies on source-text matching plus any assertion containing default_task, so an unrelated placeholder test can still satisfy the guard. Could you please update it to verify an actual import/call of the family support resolver and tie the default_task assertion to the resolved support result? It would also be helpful to update the tested revision in the PR description, since 393ab02 is the base rather than the current implementation head. Once these changes are pushed and the public CPU checks pass, I’ll trigger Internal CI for you. Thanks |
Require tests/test_support.py to import and call the family support resolver (or resolve_family), bind its result, and compare that bound result's default_task. Text-only, unbound, and wrong-object placeholders no longer satisfy the guard. Add regression cases for those false positives.

Match only exact resolver call paths.
_imported_resolvers accepts every symbol imported from families.<family>.support, not only the family resolver describe. For example, FamilySupport is importable from families.eagle_vlm.support; constructing it and asserting default_task can satisfy the checker without calling describe.
The module-import branch stores only families. It therefore rejects families.<family>.support.describe(...) because _is_resolver_call checks only the immediate attribute receiver.
Restrict family-support imports to describe. Store complete module-qualified paths, including aliases, and compare them with _attribute_path. Keep resolve_family as the separate resolver from tensorrt_model_connect.model_support.

Track resolver bindings by scope and reaching definition.
resolved is module-wide, so a resolver binding in one function can validate the same name in another function. A later non-resolver assignment does not remove the name. The guard can therefore accept support.default_task when support refers to an unrelated object.
Use scope-local forward dataflow. Record a name only when a resolver assignment reaches the assertion, and invalidate it on every later assignment to that name. Add helper tests for cross-function bindings and reassignment.

@chaofengw-nv all public CPU gates are green on dfd5dcc (Community CPU / Required passed at the new head). The un-internal-ci label was auto-removed earlier because the CPU gate had not finished; could you re-apply it when convenient? The Dev GPU lane remains blocked on the same Brev �pc.pool.count quota, unrelated to this change. |

Background
website/docs/extend/add-model-family.md(migration step 5) requires a family migrated to the semantic Task SDK to keep checkpoint identity and default-task assertions in a dependency-freetests/test_support.py. The public CPU premerge gate discovers everyfamilies/*/tests/test_support.py, but nothing enforced that the file exists.13 already-migrated timm families keep those assertions only in
tests/test_model.py, whose module starts withpytest.importorskip("tensorrt"). On the GPU-free public CPU gate those assertions are skipped, so their support contract is not exercised. This change adds the missing guard and backfills the 13 families.Refs #1401.
Exit Criteria
tests/test_support.pyis missing.Implementation
test_migrated_families_own_dependency_free_support_teststotools/tests/test_architecture.py. It discovers semantic Task interfaces fromcore/runtime/include/trtmc/internal/and reuses the existing_declared_task_interfaces/_implemented_task_idshelpers, so the requirement follows the actual family binding instead of a central list._family_runtime_sourcefor the shared runtime source scan used by the new test.tests/test_support.pyfor timm_efficientnet, timm_inception, timm_inception_resnet, timm_inception_v4, timm_mobilenetv2, timm_mobilenetv3, timm_mobilenetv4, timm_regnet, timm_resnest, timm_resnet, timm_swin, timm_vit, and timm_xcit. Each file assertstasks == ("image_to_class_scores",)anddefault_task == "image_to_class_scores"for one representative architecture, and that an unrelated identity is not claimed.Change categories
