20 development pairs, one per repository, 4 per language, 5 per family; identities
in a gitignored manifest, counts and digest committed. Executor smoke drives one
executor task end to end without a model and fails loudly on an unread clone.
kube-ax operator constraints as steering.

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.

Replaces the accepted key-exposure exception: the key never shares a sandbox with
repository code; executor AX tasks exchange commands and results via presigned
objects. Firecracker executors only if the pilot build-failure rate requires it.

kube-ax probe: AX tasks have no capabilities (no namespaces, no setuid), so no
in-task isolation. Demos become data the verifier executes; the explore key risk is
accepted and bounded by cap and rotation.

Probe runs each oracle toy pair with a real demo and two gaming demos, records
image facts, RSS and disk, fails loudly if isolation is unavailable; dispatchable
as an AX task. Worker: reason step without tools, explore tool loop whose run tool
goes through the sandbox with a scrubbed env (model key absent), spend reserved
before each call. Host probe: 5/5 real demos demonstrated, 10/10 gaming demos
inconclusive. 89 tests.

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.

The verifier, not the artefact, observes the effect: SQL, path, command and SSRF
oracles owned by the verifier (XSS needs a browser executor, else no_oracle);
artefact exit code and output ignored; immutable checkout and dependencies;
3 runs per side; one-sided build or readiness failure is inconclusive. An
isolation failure raises IsolationUnavailable instead of reading as
could_not_build (the NPROC limit now applies inside the user namespace).
35 tests, including gaming attempts and 300 host processes.

False alarms count every visible finding; the verifier owns per-family oracles;
inconclusive on one-sided build failure; feasibility pilot separated from a
73-negative BLOCK qualification; coverage ceilings; spend reserved before calls;
key isolated from executed code; cluster model calls supersede the pool VM-only
rule for this arm only. Requirements approval reopened.

After reviewing Cairn: detection so far classified excerpts and hit a precision
wall; this adds directed search with an objective goal (a re-verified
demonstration), a fact/intent board, and reason/explore steps as AX Tasks on
kube-ax. Design only learns from Cairn (AGPL); no code copied.
