Inventory recorded Oct 19, 2026 — 8:20 PM as rev 2. Listing calls only — tools are never invoked.
Canonical contract hash
sha256:31ba74d72dc394052a161536ef44df4dd3cef154b8a325b11d4729f6fb498170
Computed centrally from the normalized capability inventory (normalizer v1). Scanners submit raw observations; the control plane normalizes and hashes, so every scanner agrees on the same value.
