+# Phase 1.0AO: offline worker supervisor model
+
+Status: `HOST_PREEMPTION_OWNERSHIP_MODEL_COMPLETE_TARGET_FEASIBILITY_UNPROVEN`
+
+Date: 2026-07-29
+
+The capability-free architecture isolates the potentially blocking copy and
+temporary credentials in a one-shot worker. The persistent supervisor changes
+no credentials. It accepts only a result bound to the exact worker identity,
+exact requested byte count and zero restoration-failure bits.
+
+A deadline terminates and reaps the worker. Once copy start is attempted, every
+deadline, malformed/wrong-identity result, partial copy, restoration failure or
+ambiguous start additionally terminates and reaps the child. Any terminal
+cleanup failure is a hard error. The supervisor performs no retry and never
+automatically restarts a worker or service.
+
+This model does not prove that PS5 userland can create and uniquely identify
+such a worker, preempt one blocked inside the relevant syscall, or return a
+bounded authenticated result. It contains no process, signal, clock, IPC,
+network or target interface. A source-feasibility audit is required before
+target code can be considered.
