Standalone-workspace prototype proving the buffer-ownership model P2 requires before any production io_uring work: buffer and fd are owned by the driver's pending table from SQE submission to CQE, dropping the future never reclaims the buffer, IORING_OP_ASYNC_CANCEL only accelerates the CQE, and shutdown drains to in_flight == 0 before the ring is unmapped. Deliberately excluded from the rustfs workspace (own [workspace] table): P2 stays deferred per the P1.5 NO-GO gate, so io-uring must not enter the main Cargo.lock. Verified via run-docker.sh on a real Linux kernel: default-seccomp leg degrades gracefully (EPERM probe, the #4313 environment), unconfined leg passes all five cancel-safety tests.
