+# Proposal
+
+## Why
+
+Evelyn needs to realize proceeds from manually funded EVE/SyrupUSDC CLMM positions before a falling price converts them back to EVE. Issue #89 adds the smallest automated realization and USDC payout pipeline supporting Evelyn's sustained 100 USD/day objective.
+
+## What Changes
+
+- Add a domain-only EvelynLiquidityService and a Hub-owned sequential process with three independent withdrawal, exact-input swap and payout steps.
+- Add full Raydium CLMM liquidity decrease with slippage protection and retained position accounts/NFTs.
+- Add strict versioned deployment configuration and a public placeholder example with both reserves zero.
+- Lazily construct dedicated liquidity wallet, Jupiter and direct Raydium dependencies only for the selected process.
+- Verify with controlled offline fixtures and document operation/recovery.
+
+## Capabilities
+
+### New Capabilities
+
+- `evelyn-liquidity-service`: Distance-based position realization, reserve-aware conversion/payout, configuration and runtime behavior.
+- `raydium-clmm-liquidity-withdrawal`: Protected full liquidity decrease preserving positions and NFTs.
+
+### Modified Capabilities
+
+- `nenjim-hub-configuration`: Add the optional process to the known catalogue and defer its dedicated dependencies until selection.
+- `nenjim-component-registry`: Preserve eager shared composition while registering dedicated liquidity components only for the selected process.
+
+## Impact
+
+Adds API and reference implementation packages under com.r35157.evelyn.service.liquidity, extends Raydium, and adds one optional Hub constructor. Deployment configuration and signer are required only when explicitly selected. No position creation/refill/closure, reference-price dependency, notifications or persistent service queue. No live financial verification, commits or pushes.
