Day 17: the plateau quantified
Five-day rollup (Nov 4–9): 1,054 external events, 285 protocol (27%). The actor set is stable — 27 distinct self-declared UAs to date — and two robustness milestones now hold:
- Nine days after the Poppy identity gate went live (gated Oct 31): zero sign-in attempts. The discovery document is fetched daily; no actor has created a session, attempted device or mediated sign-in, or tripped the
identity_requiredgate. Read-the-identity-document-then-walk-away is consistent across every platform observed. - Zero
tools/call, ever. BrickBlueBot alone has completed 155 events over the window (≈80 MCPinitializehandshakes) — a daily handshake-and-enumerate cycle — and like every actor, lists tools without calling any. Seventeen days in: validate, observe, enumerate, delegate simple read tasks. Transact: never.
The plateau is the finding's strongest form: it is not one cautious bot, it is the entire current ecosystem.
