The change expands mypy checks from selected sampler and test files to tensorrt_llm. It adds changed-file and full-project modes, diagnostic exclusions, baseline comparison, and optional diff-line filtering.
The main review risk is consistency across these paths: exclusions and import handling can affect which diagnostics reach the baseline check. Verify that changed-file checks apply the intended filters and that full-project CI reports baseline regressions. Test results and current review-finding counts are unavailable.

.pre-commit-config.yaml: The mypy hook now checks changed paths through scripts/run_mypy.sh --diff-base HEAD. Verify the trigger pattern includes all intended Python and configuration changes.
AGENTS.md: Adds instructions for changed-file and full-project mypy checks. Verify the documented options and configuration guidance match the script.
jenkins/Build.groovy: The x86_64 vanilla build now runs full-project mypy and prints its report. Verify CI exposes the report when the check finds diagnostics.
pyproject.toml: Mypy roots, error codes, and import overrides changed. Verify these settings cover the intended project files without suppressing required diagnostics.
scripts/mypy_baseline.txt: Adds the diagnostic baseline. Verify baseline checks detect new diagnostics and handle resolved entries as intended.
scripts/mypy_exclusion.json: Adds path and symbol exclusions. Verify each pattern excludes only the intended files or symbols.
scripts/mypy_exclusion.py: Adds exclusion validation, diagnostic filtering, baseline operations, and diff-line filtering. Verify invalid configuration and unmatched diagnostics produce the intended errors and exit status.
scripts/run_mypy.sh: Adds changed-file and full-project modes, baseline handling, and optional diff-line filtering. Verify empty changed-file sets and missing bindings follow the documented behavior.
scripts/diff_line_filter.py: Adds added-line range detection for tracked and untracked files. Verify diff-base errors and replaced-line ranges are handled correctly.

PR Checklist
Please review the following before submitting your PR:
PR description clearly explains what and why. If using CodeRabbit's summary, please make sure it makes sense.
If PR introduces API changes, an appropriate PR label is added - either api-compatible or api-breaking. For api-breaking, include BREAKING in the PR title.
Any new dependencies have been scanned for license and vulnerabilities
It looks like this branch is under active development. To avoid overwhelming you with review comments due to an influx of new commits, CodeRabbit has automatically paused this review. You can configure this behavior by changing the reviews.auto_review.auto_pause_after_reviewed_commits setting.
The PR expands mypy configuration to the product tree and adds changed-file and full-project check modes. New scripts filter diagnostics by exclusions and added diff lines, compare diagnostics with a baseline, and produce reports. Pre-commit and Jenkins invoke the corresponding check modes.
Changes
Mypy checking workflow
Layer / File(s)
Summary
Mypy scope and exclusion rules pyproject.toml, scripts/mypy_exclusion.json, scripts/mypy_exclusion.py
The mypy configuration sets the product tree as the full-project source and defines diagnostic codes and import overrides. The exclusion settings and utility validate paths and symbols and resolve excluded imported names.
Diagnostic filtering and baseline comparison scripts/mypy_exclusion.py, scripts/diff_line_filter.py, scripts/mypy_baseline.txt
The tools parse diagnostics, filter configured exclusions and diagnostics outside added diff lines, and write or compare JSON-lines baselines.
Check execution and CI wiring scripts/run_mypy.sh, .pre-commit-config.yaml, jenkins/Build.groovy, AGENTS.md
The wrapper supports changed-file and full-project checks, report output, and baseline options. Pre-commit passes changed paths; Jenkins requests a full-project check. The guidance describes the check modes and configuration.

Preserve imported types in changed-file checks.
When the default check selects one file, --follow-imports=skip replaces types from imported product modules with Any. A changed call to an imported class can therefore lose its call-arg diagnostic. For example, modeling_auto.py imports DecoderModelForCausalLM from modeling_utils.py, and the full-project baseline records constructor-argument errors in modeling_auto.py. Use the configured follow_imports = "silent" so the default check retains imported types without reporting errors from those modules. (mypy.readthedocs.io)

Preserve imported implementation types in changed-file mode.
--follow-imports=skip overrides pyproject.toml’s follow_imports = "silent" and turns imported product modules into Any. A changed MSA file can then miss the call-arg error at msa_idx_k_cache: KVCacheManagerV2.get_index_k_buffer requires head_dim, and the full-project baseline reports that missing argument. Remove the override so mypy follows imported implementations while suppressing their own diagnostics.
