# E91 · Keys from Entanglement · instrument № 08

**What it is.** security you can watch break — CHSH 2√2 ≈ 2.83 undisturbed, ~0.7 under attack; verified

**How it works.** The Ekert 1991 entanglement protocol: a real two-qubit statevector, proper projective measurements at the Ekert angles, and a live CHSH test.

**The live example.** This emergent does not merely describe a tool — it links its working self: **[run instrument № 08 live](https://davidwise01.github.io/mimzy/bench/08-e91.html)**. Open it, operate it, and the badge's claims execute in front of you.

**The verified record.** Verified: S = 2√2 ≈ 2.83 undisturbed; S → ~0.707 under intercept-resend, exactly as theory demands.
