+# Phase 1.0AS: offline channel primitive and FD ownership audit
+
+Status: `PIPE_POLL_CANDIDATES_PRESENT_FD_INHERITANCE_AND_HARD_DEADLINE_BLOCKED`
+
+Date: 2026-07-29
+
+Current official SDK declarations and shsrv call sites make `pipe` and `poll`
+public-source candidates. The shsrv telnet loop uses a short relative poll, but
+does not compose it with an absolute monotonic deadline, EINTR budget
+recalculation or bounded worker reap.
+
+The decisive ownership mismatch is in worker creation. The official header
+defines `RFFDG` as copying the descriptor table and `RFCFDG` as closing every
+descriptor. Current shsrv workers use `RFCFDG`; a pre-created result pipe would
+therefore not be inherited. No reviewed worker path uses `RFFDG` with exclusive
+parent/child pipe-end closure or close-on-exec handling.
+
+Headers alone do not prove that a new composition is safe on firmware 9.60.
+The next phase may model FD acquisition, inheritance, close ordering, EINTR and
+an absolute deadline using fake operations only. No live channel, target source,
+build or device action is authorized.
