+## TidalYield × TidalProtocol Liquidation Test Plan
+
+### Scope
+- Validate behavior when FLOW price decreases enough to undercollateralize the internal `TidalProtocol.Position` used by a Tide via `TracerStrategy`.
+- Cover two paths:
+  1) Rebalancing recovers health using YieldToken value (via AutoBalancer Source → Yield→MOET top-up) to Position target health ≈ 1.3.
+  2) With Yield price forced to 0, rebalancing cannot top-up; a liquidation transaction is executed to restore health to liquidation target ≈ 1.05.
+
+### Architecture Overview (relevant pieces)
+- `TidalYieldStrategies.TracerStrategyComposer` wires:
+  - IssuanceSink: MOET→Yield → deposits to AutoBalancer
+  - RepaymentSource: Yield→MOET → used for top-up on undercollateralization
+  - Position Sink/Source for FLOW collateral
+- `DeFiActions.AutoBalancer` monitors value vs deposits (lower=0.95, upper=1.05) and exposes a Source/Sink used by the strategy.
+- `TidalProtocol.Pool.rebalancePosition` uses `position.topUpSource` to pull MOET (via Yield→MOET) and repay until `targetHealth` (~1.3).
+- Liquidation (keeper or DEX) drives to `liquidationTargetHF` (~1.05), separate from rebalancing.
+
+### Tests
+1) Rebalancing succeeds with Yield top-up
+   - Setup Tide/Position with FLOW collateral.
+   - Drop FLOW price to make HF < 1.0.
+   - Keep Yield price > 0.
+   - Call `rebalanceTide` then `rebalancePosition`.
+   - Assert post-health ≥ targetHealth (≈ 1.3, with tolerance) and that additional funds required to reach target is ~0.
+
+2) Liquidation with Yield price = 0
+   - Setup as above; drop FLOW price to make HF < 1.0.
+   - Set Yield price = 0 → AutoBalancer Source returns 0, top-up ineffective.
+   - Execute liquidation:
+     - Option A (keeper repay-for-seize): `liquidate_repay_for_seize` using submodule quote.
+     - Option B (DEX): allowlist `MockDexSwapper`, mint MOET to signer for swap source, execute `liquidate_via_mock_dex`.
+   - Assert post-health ≈ liquidationTargetHF (~1.05, with tolerance).
+
+### Acceptance criteria
+- Test 1: health ≈ 1.3e24 after rebalance (± small tolerance), no additional funds required.
+- Test 2: health ≈ 1.05e24 after liquidation (± small tolerance), irrespective of Yield price (0).
+
+### Notes
+- Rebalancing never targets 1.05; it targets `position.targetHealth` (~1.3). Liquidation targets `liquidationTargetHF` (~1.05).
+- For DEX liquidation, governance allowlist for `MockDexSwapper` and oracle deviation guard must be set appropriately.
