+# Phase 1.0AN: offline service lifecycle and copy audit
+
+Status: `FAIL_STOP_PRESENT_RESTART_AND_BOUNDED_COPY_UNPROVEN_TARGET_CODE_BLOCKED`
+
+Date: 2026-07-29
+
+The hardened elfldr fork has a real fail-stop for its ptrace credential scope.
+If restoration of the temporary auth ID fails, a process-global latch rejects
+all later ptrace calls. After the current request and its cleanup attempt, the
+socket service calls `_exit(125)`.
+
+That proves process termination, not safe recovery. No reviewed source owns a
+bounded restart, verifies the identity of a replacement service, or proves
+cleanup when startup-level credential restoration fails. Automatic restart is
+therefore forbidden.
+
+The alternative `pt_copyin` route is also insufficient. It issues one blocking
+`PT_IO` request and does not validate returned descriptor progress. The source
+has neither a hard deadline/preemption mechanism for that call nor proof that a
+successful return means the exact requested byte count. It cannot replace the
+unsafe SDK `mdbg_copyin` merely because it changes fewer credentials.
+
+The next work may only design a host-only preemption and service-owner
+architecture. No target source, build, connection, transfer, restart or device
+execution is authorized.
