+
+## Verification status
+
+The deterministic package suite and the real embedded-PostgreSQL Paperclip
+suite prove selection, replay/conflict handling, authoritative evidence,
+status/liveness atomicity, session/finalization recovery, migration repair,
+bounded cancellation/retry, and a byte-equivalent legacy read snapshot. The
+database suite is the internal native canary: it executes one selected task
+through the public package session contract and applies one server-owned
+decision. Its post-kill-switch legacy case has zero native history rows.
+
+No new live provider task was dispatched during the remediation review. A live
+Codex canary remains an operator-run rollout check because it requires changing
+the instance flag and one agent profile. The package `trace:phase6` command is a
+mock contract tracer; real Paperclip proof is the database-backed server matrix
+and the explicitly gated procedure in the tutorial.
