+# Phase 1.0AM: offline bounded copy and restore model
+
+Status: `HOST_EXACT_PROGRESS_AND_RESTORE_MODEL_COMPLETE_TARGET_CODE_BLOCKED`
+
+Date: 2026-07-29
+
+The capability-free model replaces the unsafe semantics identified in Phase
+1.0AL. It validates 64-bit source and destination ranges, bounds total size,
+chunk count and synthetic ticks, rejects zero or oversized progress, and
+accepts completion only at the exact requested byte count.
+
+Auth ID and capabilities are both backed up before modification. Every field
+that changed is independently restored on every exit, with separate failure
+bits. A partial copy requires child termination and reap. Any credential
+restore failure additionally requires termination of the now-untrusted service;
+failure of either terminal cleanup operation is a hard error.
+
+Successful exact copy keeps the child alive for subsequent loader stages. This
+is only host-model behavior. The model imports no credential, process, memory,
+clock, network or target interface and does not establish the undocumented
+remote status semantics or firmware-9.60 behavior. Target implementation stays
+blocked pending service-lifecycle ownership and source review.
