State Latch Fix for the Static Fire Feb 2026

[SwiftGapple]

• A switch latch bug was discovered during the static fire
• Trigger condition: Launch Mode -> ARM Switch ON-> Launch Button -> DEV Mode -> ARM Swtich OFF -> Launch Button
• When performing a launch (usually cold flow before static fire), and close the ARM switch outside of the launch mode, there will be a very brief moment that the ground station will sent ARM ON state to the flight computer when entering the launch mode again. This is due to the debounce switch reading mechanism.
• This branch has been archieved in static-fire-Feb2026-record
• The current main branch has patched this fix to enforce a 2 second sensor read stabalization time when swtiching state, as well as a state check when entering the launch mode. Any invalid state will prevent entering the launch mode and revert back to the previous state.
