📝 WalkthroughWalkthroughAdded a new TAVA architecture diagram file with corresponding governance and process updates. The CODEOWNERS file assigns ownership of the diagram to the design team and designates a release branch approval team. The PR template now includes a reminder to update the architecture diagram.

52-52: Optional: capitalize “TAVA” for consistencyConsider changing to
Update [TAVA architecture diagram] ...so the acronym matches other usages (e.g., team name, diagram section header)..github/tava_architecture_diagram.md (1)
36-50: Minor cleanup: typo, duplicate node label, and unused API nodesA few small polish items in the diagram:
- Line 97:
%% Shared Componnet format– typo in “Componnet”.PyEngineis declared asPyEngine[PyTorch Engine]and then re-declared inPyExecutor --> PyEngine[PyTorch Engine]; you can referencePyEnginewithout relabeling to avoid duplication.class PythonAPI,CppAPI,LLMAPI api;stylesPythonAPIandCppAPI, but those nodes are never defined in the graph.Suggested minimal diff:
- PyEngine[PyTorch Engine] + PyEngine[PyTorch Engine] @@ - PyExecutor --> PyEngine[PyTorch Engine] + PyExecutor --> PyEngine @@ - %% Shared Componnet format + %% Shared Component format @@ - class PythonAPI,CppAPI,LLMAPI api; + class LLMAPI api;These don’t affect behavior but keep the diagram cleaner and easier to maintain.

Learning: For PR templates in TensorRT-LLM, avoid suggesting changes that would increase developer overhead, such as converting plain bullets to mandatory checkboxes. The team prefers guidance-style bullets that don't require explicit interaction to reduce friction in the PR creation process.

Learning: The teams NVIDIA/trt-llm-release-nim-branch-approval and NVIDIA/trt-llm-release-branch-approval exist in the NVIDIA organization and are valid for use in .github/CODEOWNERS files, even if they may not be accessible via external API queries due to permissions.

Timestamp: 2025-08-11T20:09:24.389Z
Learning: In the TensorRT-LLM test infrastructure, the team prefers simple, direct solutions (like hard-coding directory traversal counts) over more complex but robust approaches when dealing with stable directory structures. They accept the maintenance cost of updating tests if the layout changes.

Timestamp: 2025-08-06T13:58:07.506Z
Learning: In TensorRT-LLM, test files (files under tests/ directories) do not require NVIDIA copyright headers, unlike production source code files. Test files typically start directly with imports, docstrings, or code.

Timestamp: 2025-07-28T17:06:08.621Z
Learning: In TensorRT-LLM testing, it's common to have both CLI flow tests (test_cli_flow.py) and PyTorch API tests (test_llm_api_pytorch.py) for the same model. These serve different purposes: CLI flow tests validate the traditional command-line workflow, while PyTorch API tests validate the newer LLM API backend. Both are legitimate and should coexist.

Timestamp: 2025-08-26T09:49:04.956Z
Learning: In TensorRT-LLM test configuration files, the test scheduling system handles wildcard matching with special rules that prevent duplicate test execution even when the same tests appear in multiple yaml files with overlapping GPU wildcards (e.g., "*b200*" and "*gb200*").

File: tests/integration/test_lists/waives.txt:313-313
Timestamp: 2025-09-17T02:48:52.732Z
Learning: In TensorRT-LLM, `tests/integration/test_lists/waives.txt` is specifically for waiving/skipping tests, while other test list files like those in `test-db/` and `qa/` directories are for different test execution contexts (pre-merge, post-merge, QA tests). The same test appearing in both waives.txt and execution list files is intentional - the test is part of test suites but will be skipped due to the waiver.
