[P1] Burn-toll floor-liquidity spec — minimum AMM pool depth per volume tier

[abhicris]

Burn toll requires the protocol to market-buy CR8 from an AMM pool on every mint/redeem. At $100K pool depth, a $10K mint moves CR8 price ~10% — wrecks the toll math.

Scope

Document the minimum pool depth required for the toll to function at each CR8-USD volume tier.

• Derivation: given pool_depth, mint_size, compute price-impact on CR8 side and show tolerable-loss envelope.
• Table:

Monthly CR8-USD volume	Min CR8/USDC pool depth	Max single mint	Notes
$100K	$?	$?
$1M	$?	$?
$10M	$?	$?

• Policy: if pool depth drops below threshold, BurnToll.sol skips the toll (see kcolbchain/stablecoin-toolkit#18). Document the skip-log + alert routing.

Output

cr8-burn-toll-liquidity.md. Feeds the floorPoolMinDepth default in the extension.
