[P1] CR8-USD depeg defence policy spec (triggers, states, operator runbook)

[abhicris]

Spec the depeg defence for CR8-USD. Drives the implementation in kcolbchain/stablecoin-toolkit#19.

Scope

Document-only. The code lives in the toolkit. What goes here:

• Trigger thresholds (bps off-peg, minutes sustained) for Caution and Hard states.
• Price source hierarchy — Chainlink USDC/USD primary, Uniswap TWAP fallback, manual override (how?).
• State transitions — who can trigger each? Auto (contract-level) vs governance (timelocked)?
• Emergency pool sizing — what fraction of reserve sits in the emergency USDC pool vs auto-parked into Lucidly?
• Holder communication plan — state dashboard, Telegram alert, Discord post, Twitter banner — what fires where.
• Post-incident unwind — what conditions return to Normal, who signs off.

Output

cr8-depeg-policy.md — publishable policy document. Links from cr8-canonical.md (#1).

Why

• gtm-review-2026-04-13.md §Missing-or-soft item 4.
• Required before any real capital deploys. SVB-redux is the textbook scenario.

Depends on

• #1 (cr8-canonical) — resolve CR8-USD launch timing first.
