Feed the milestone back into the spec and steering. HANDOFF: the open "first demonstrated"
question is RESOLVED -- xiaomusic (path, prefix-check-bypass) demonstrated on the vulnerable
side (3/3 affected, 0/3 safe) and the blind fixed-side search produced 0 false proofs; pair
total $1.22. Records the six-fix chain that enabled it (parity, verify-time-only, fair-share
budget, served-root guidance, oracle prefix-bypass coverage, control-signal feedback) plus the
keystone. tasks.md: implementation note; pilot (6.2/6.3) in progress. spec.json: pilot status.
safety-net steering: proof-based BLOCK mechanism reached first execution-backed demonstration
(feasibility-pilot scope, not release readiness; pilot exit + 73-negative qualification open;
classifier stays triage). search README: status note. Payload-free; demos/boards stay gitignored.

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.

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.
