the established tolerance-based behavior, using math.isclose with an absolute

🎯 Functional Correctness | 🟠 Major | ⚡ Quick win
Exact float equality for CameraInfo D/K/R/P risks spurious fail-closed shutdowns.
_sequence_matches uses float(value) == reference to compare live CameraInfo intrinsics/distortion against the calibration YAML. Values traverse the RealSense driver and a YAML text round-trip before comparison, so a benign floating-point rounding difference would trigger _fail() and shut down the whole runtime bringup — even though the camera is correctly calibrated. Note that calibration.py's own validation (e.g. T_parent_child/translation checks) already uses math.isclose(..., abs_tol=1.0e-12) for equivalent floating comparisons, making this exact-equality check inconsistent with the rest of the contract.

Name the noise file and parameters explicitly.
This README names the default file as px4_imu_noise_unvalidated.yaml but later refers to seeker_imu.yaml. It also lists 0.09 / 0.05 / 0.06 / 0.001 without field names, while the documented order is gyro noise, gyro random walk, accelerometer noise, and accelerometer random walk. Use the exact current path and named values to prevent auditing or reproducing the wrong noise contract.

Drop deprecated tests_require.
Recent setuptools versions it seems that tests_require was removed - it was deprecated for a while, emitting an "Unknown distribution option" warning on install. package.xml already declares python3-pytest as a test_depend, so this is redundant and will eventually just produce noise.

📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick win
Both test files exec/compile extracted source to test pure validators — flagged as error-severity by static analysis. Root cause: imu_measurements_are_finite and odometry_measurements_are_finite live in modules that import rclpy/sensor_msgs/nav_msgs, so tests can't import them directly without a ROS runtime, and fall back to AST-extraction + exec. This trips Ruff S102 and ast-grep's no-exec/no-compile rules (CWE-94) at error level in both files, which risks failing CI lint gates.

Avoid grep -q in these pipefail checks.
A valid match can still fall into [STOP] if the producer keeps writing after grep -q exits early and pipefail turns the SIGPIPE into a failure. This affects the checks at 680-683, 728-731, and 871-881; use a here-string or another non-piped form instead.

Make the missing Allan-file branch fail explicitly.
When PX4_IMU_NOISE_FILE is missing, this block only prints [STOP] and returns success, so a wrapper script or copied multi-step procedure can continue. Add exit 1 (or return 1 when sourced) before the else branch.
