+# Phase 1.0DO: inactive one-shot snapshot runner
+
+Status: `OFFLINE_RUNNER_COMPLETE_INACTIVE`
+
+The runner pins the 109,896-byte DM artifact and its SHA-256, accepts only a
+numeric IPv4 target on port 9021, and requires byte-identical activation and
+separate approval records. It creates and flushes an exclusive consumed
+receipt before constructing a socket. It then permits exactly one connection,
+one complete ELF send, one write-half-close, and at most 67,108,992 received
+bytes within a 30-second total result deadline. The snapshot itself is created
+exclusively and sealed only after an exact terminal frame and SQLite header.
+
+The tracked manifest and approval template are deliberately inactive. They do
+not contain a target, run ID, paths, time window, or authority. Host tests do
+not constitute PS5 evidence. No console action is authorized by this phase.
