Fallback strategies

ELI5: When Coil doesn't need more capital, Keep parks USDC in boring yield — Curve TARE liquidity, Aave, Compound, or Morpho.

What you can do

Users don't interact directly — vault manager/keeper allocates via rebalance().

Flywheel fit

Strategy	Flywheel role
CurveTAREStrategy	TARE/USDC LP — peg liquidity
AaveV3Strategy	Generic lending yield
CompoundV3Strategy	Comet + COMP harvest
MorphoStrategy	Morpho Blue supply

Used only when CoilMakerStrategy cannot absorb more (max_debt / idle flow).

Contract walkthrough

Common pattern (khomdev-keep/src/strategies/):

1. deposit / withdraw — vault-only (msg.sender == vault)
2. getApr() — governance-set bps (off-chain keeper updates)
3. harvest() — claim rewards, swap, re-supply (Compound); no-op on Aave (rebasing aTokens)

Strategy	Harvest
AaveV3	No-op (aToken rebase)
CompoundV3	COMP → USDC via Uniswap V3
Morpho	Market-specific
CurveTARE	LP fees / gauge logic

Smart routing formula when enabled:

target_debt_i = total_assets × APR_i / Σ APR_j

Capped by each strategy's max_debt.

What can go wrong

Risks

• External protocol risk (Aave/Compound/Morpho/Curve).
• APR is keeper-set — stale APR → suboptimal routing.
• Curve IL on TARE/USDC position.
