In `@jenkins/scripts/run_tests.py`:
- Line 420: Rename the ambiguous variable `l` to `line` in the list
comprehension that builds `isolate_tests` (the expression currently
"isolate_tests = [l.strip() for l in Path(isolate_list).read_text().splitlines()
if l.strip()]"); update all uses inside that comprehension to `line` (i.e.,
"line.strip()" and "if line.strip()") to satisfy the linter and improve
readability.
- Around line 321-324: Rename the ambiguous variable `l` in the list
comprehension that reads rerun_file to a descriptive name (e.g., `line`) to
resolve ruff E741; specifically update the expression in the block using
`Path(rerun_file).read_text().splitlines()` so it becomes `lines = [line for
line in ... if line.strip()]`, leaving the surrounding variables (`rerun_file`,
`rerun_tag`, `times`, `valid_count`) and logic unchanged.
- Around line 636-639: Comprehensions that compute regular_count and
isolate_count use the single-letter variable name `l`, causing E741 ambiguous
variable-name failures; update both comprehensions to use a clear name like
`line` (e.g., replace `l` with `line` in the list comprehensions that read from
Path(regular_list).read_text().splitlines() and
Path(isolate_list).read_text().splitlines()) so the variables regular_count and
isolate_count are computed without the ambiguous-named iterator.
In `@jenkins/scripts/slurm_run.sh`:
- Around line 109-130: The runTestsArgs array currently includes an unquoted
variable $perfModeFlag which, when empty, can produce word-splitting issues;
update the array construction (around runTestsArgs and perfModeFlag) to either
add perfModeFlag conditionally (only push/perfModeFlag when perfMode is "true")
or ensure it's quoted/handled so the empty value doesn't expand into extra empty
array elements—modify the code that sets perfModeFlag and the runTestsArgs array
population (references: perfModeFlag, runTestsArgs, runTestsScript) to perform a
conditional append or use a safe quoted expansion.

Fail on every test-collection error.
run_tests.py continues when pytest --collect-only returns nonzero and stdout is nonempty. This invocation can then run a partial shard and report success. Make the runner fail before it parses collection output whenever result.returncode != 0.

Apply the rerun cap across isolated tests and add the NVIDIA copyright header.
run_isolated_tests calls check_and_rerun inside its per-test loop. The stage can therefore exceed five isolated reruns. Track the cap across the full isolated-test stage. Add the required NVIDIA copyright header to jenkins/scripts/slurm_run.sh.

Do not interpolate runner arguments into single-quoted shell arguments.
An apostrophe in pytestCommand or failSignaturesList terminates the shell argument and prevents run_tests.py from starting. Pass these values through withEnv, then use quoted shell-variable expansions.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Substring matching can classify a test into the wrong bucket.
next((t for t in isolation_tests if trimmed in t), None) matches on containment. If one collected id is a substring of another list entry, the test maps to the wrong entry. Examples: test_foo matches test_foo_extended, and a bare parametrized prefix matches several ids. The result is an isolation test executed as regular, or a regular test executed under a different id.
Prefer exact matching, with a fallback only when the collected id is a suffix after the :: separator.

Handle non-rerunnable failures as failures.
A failed test that exceeds 10 minutes without a matching signature is written only to rerun_0.txt. Since check_and_rerun processes only rerun_1.txt and rerun_2.txt, the original non-zero pytest result is reported as passed. Propagate this failure or process rerun_0.txt as a non-rerunnable failure.
