Demos are data the verifier executes (fixed build recipes, runtime+path start,
HTTP/CLI steps with captures; the canary is never referable). The agent loop with
the key never runs repository code: executor tasks without a key exchange commands
and results through presigned objects. AX capacity errors are back-pressure with at
most 2 tasks in flight; caches and builds under /workspace with a 2 GiB guard;
verifiers take one presigned archive per side. Launcher fix: private /dev in bwrap.
190 tests on the host; probe 5/5 demonstrated.

The kube-ax probe showed bwrap cannot map uids in gVisor as an unprivileged user.
As root (gVisor is the outer boundary) the sandbox uses pid/ipc/uts/net/mount
namespaces without a user namespace and drops the artefact to its own uid via
setpriv; the mode is recorded. The probe reports each namespace kind separately.

Board as immutable versioned blobs (coordinator sole writer); budget reserve/settle
before model calls; per-task and run caps; coordinator loop over an injected
executor; batch.py accepts a fixed allow-list of search variables; XSS browser
oracle; ousast-search-task image (Python, Node/TypeScript, PHP, Java 17, sqlite,
bwrap, chromium) built by CI. 103 tests on the host.
