The rung this project deliberately does not build. Clearwing already runs sandbox lifecycles, container pools, sanitizer images, PoC replay and stability classification, and the corrective brief concluded -- from this project's own defect history -- that reimplementing that machinery is where we go wrong. So model/execution.py decides eligibility, calls an adopted tool, and records what happened. A test asserts structurally that it imports no container or subprocess machinery and defines no build/run/compile/patch function, because the failure mode to prevent is this file quietly growing a sandbox. Eligibility is narrow in both directions: only a family a static model cannot arbitrate (memory safety in C, where the bug turns on runtime layout -- Req 10.3 forbids any web/logic family depending on this tier, and each now has taint, dominance or constant abstraction instead), and only a finding the model left undecided. The tier escalates uncertainty; it never re-checks a verdict. One deliberate asymmetry: a failure to reproduce is NOT a refutation. A sandbox that does not trigger a bug has not shown the bug is absent, only that this attempt did not trigger it, so the candidate stays where the model left it. Reading a failed reproduction as a clean bill of health is the same error class as reading an absent engine as "no vulnerability". With no adopted tool present -- the normal case -- the rung is never reached and clearwing_unavailable is recorded. All 16 tasks of model-grounded-detection are now done. 720 passing, mypy/ruff clean, gates byte-identical, zero orphaned modules.
