⚓ Making Autonomous AI Agents Insurable

The Plimsoll line, a CI gate, and the buyer who is never the developer — with the behaviour cage slipped in twice.

❌ Errata, line by line

• “We are just guaranteeing it didn't break out of its mathematical cage?” 00:31We guarantee the deviation is detected, placed, priced and dispatched. Whether the agent kept to the line is what the receipt shows, after the fact, to someone who is not the agent.promises the agent stays inside a line · settled by CLAUDE.md NEVER GUARANTEE BEHAVIOR · scripts/vna/public-surface-register.mjs CAGE
• “Unverified AI means a $2.5 million deductible.” 01:04UNSOURCED — no file in the repo carries this deductible or the $250,000 it drops to. Held off every page until a source exists.a number no repo file carries · settled by open question 1

✅ Said right, quoted as said

• “Think of the Plimsoll line, painted on 18th century merchant ships.” 00:12
• “Underwriters didn't need to know how to sail the ship.” 00:15
• “Wait, so we aren't promising the AI is actually smart or correct?” 00:28
• “Devs hate friction, so who actually forces them to install this gatekeeper?” 00:53
• “The people with the money.” 00:57
• “Who is the real buyer here? It's never the developer.” 01:12
• “It's a nightclub bouncer who doesn't care about your excuses.” 00:46

✏️ Nearly right, and the line we would sign

• “They just needed a visible, unfakeable mark proving it wasn't overloaded.” 00:17→ They just needed a visible mark, painted before the voyage, that anyone on the dock could check against the waterline.the mark is a declared line read by someone who is not the captain; 'proving it wasn't overloaded' slides from placement into a behaviour claim
