# MovementTest Solver Timeout Design

## Goal

Allow the trajectory-observation MovementTest to give OSQP enough time to produce its first test trajectory without loosening solver accuracy or vehicle safety constraints.

## Scope

- Add `SolverTimeoutSeconds` to `TrajectoryObservationSettings`, defaulting to `0.50` seconds.
- Validate and snapshot that setting with the existing observation settings.
- Expose it as a MovementTest field and pass it into the observation settings.
- Copy the setting to `EmPlannerConfiguration.Scheduling.SolverTimeoutSeconds` when the observation controller is created.

## Non-goals

- Do not change the `1e-5` OSQP or strict residual tolerances.
- Do not change vehicle, map, speed, acceleration, or control-command behavior.
- Do not modify the production EM default configuration; this is an observation-test override only.

## Verification

The observation verification host will prove a custom timeout survives settings snapshotting and is present on the EM planning request. Existing observation and full EM verification suites must remain green.
