Micro Survey Drone

A palm-sized survey drone that crawls or hovers through ducts, crawlspaces, and unstable rooms while streaming a coarse map home. Operators teach it return points and no-go surfaces before release. Dust clogs the lift vanes; magnetic grit confuses its heading. The resulting map includes access routes that rescuers need and thieves would happily purchase. Praxis recommends a bench check after hard use; skipped certificates are cheap until an insurer asks for the last valid one. Loan crews sign for Micro Survey Drone by serial because its stored surveys can expose claims, routes, and work nobody declared. Returning it clean is maintenance; returning it empty looks like intent.
