TARDIS Primary Exterior Hatch (Physical Subsystem)
A physical subsystem of the TARDIS, distinct from the vessel itself. Functions as a localized point of failure (e.g., jamming, requiring manual intervention) and is directly interacted with by characters in physical scenes (e.g., the Doctor prying open the doors). Not to be confused with the TARDIS vessel itself.
