+# Phase 1.0DF: inactive title-presence observer
+
+Status: `HOST_OBSERVER_CONTRACT_COMPLETE_LIVE_REQUEST_UNFORMABLE`
+
+Phase 1.0DF implements only a pure host contract and synthetic result model.
+It has no socket, target, CLI, clock, file output, target source or artifact.
+No PS5 request or other device action occurred.
+
+The model recognizes two future method classes. `SOURCE_BOUND_QUERY` requires
+an independently proven read-only query ABI. `EXACT_PATH_METADATA` requires a
+literal absolute path plus separate provenance for that exact mapping. It does
+not derive a path from `PPSA01659`, enumerate a directory, use a shell or guess
+fallback locations.
+
+Both methods bind firmware 9.60, title `PPSA01659`, exact request bytes, one
+read-only request and at most 4,096 result bytes. Only a complete, explicitly
+typed PRESENT or ABSENT response may produce that classification. An error,
+EOF, incomplete response or ambiguity always produces UNKNOWN; an error is
+never interpreted as title absence.
+
+The current source set provides neither an independent query ABI nor an exact
+title path. A request cannot therefore be formed and the tracked activation is
+empty. The synthetic tests demonstrate policy behavior only, not firmware or
+device evidence. A live client, shsrv command, title launch, app termination,
+device write, retry and reconnect remain forbidden.
