+# Slippage Mapping
+
+This document describes how `SlippageBps` is derived for each supported swap protocol in this repository.
+
+## Unified Fields
+
+Each parsed `Swap` may include these normalized fields:
+
+- `SwapMode`
+- `FixedAmount`
+- `FixedAmountSide`
+- `FixedMint`
+- `LimitAmountType`
+- `LimitAmount`
+- `LimitAmountSide`
+- `LimitMint`
+- `ActualLimitAmount`
+- `ActualLimitAmountSide`
+- `SlippageBps`
+
+## Internal Enum Mapping
+
+These fields are stored internally as `uint8` enums and serialized as strings in JSON / debug output.
+
+### `SwapMode`
+
+| Raw Value | Name | Serialized Value |
+| --- | --- | --- |
+| `0` | `SwapModeUnknown` | `""` |
+| `1` | `SwapModeExactIn` | `"exact_in"` |
+| `2` | `SwapModeExactOut` | `"exact_out"` |
+
+### `SwapAmountSide`
+
+Used by:
+
+- `FixedAmountSide`
+- `LimitAmountSide`
+- `ActualLimitAmountSide`
+
+| Raw Value | Name | Serialized Value |
+| --- | --- | --- |
+| `0` | `SwapAmountSideUnknown` | `""` |
+| `1` | `SwapAmountSideBase` | `"base"` |
+| `2` | `SwapAmountSideQuote` | `"quote"` |
+
+### `SwapLimitType`
+
+Used by:
+
+- `LimitAmountType`
+
+| Raw Value | Name | Serialized Value |
+| --- | --- | --- |
+| `0` | `SwapLimitTypeUnknown` | `""` |
+| `1` | `SwapLimitTypeMinOut` | `"min_out"` |
+| `2` | `SwapLimitTypeMaxIn` | `"max_in"` |
+
+## Calculation Rules
+
+- `exact_in`
+  - `SlippageBps = (actual_out - min_out) / actual_out * 10000`
+- `exact_out`
+  - `SlippageBps = (max_in - actual_in) / max_in * 10000`
+
+Interpretation:
+
+- Positive: execution is better than the user limit
+- Zero: execution lands exactly on the user limit
+- `10000`: user limit is effectively unbounded on the constrained side (for example `min_out = 0`)
+- Negative raw headroom is clamped to `0` because successful-swap storage uses a non-negative bounded metric
+
+This definition makes `SlippageBps` a bounded "remaining headroom to the user's limit" metric for successful swaps:
+
+- `exact_in`: how much output headroom remained, measured against the realized output
+- `exact_out`: how much input headroom remained, measured against the allowed max input
+
+## Protocol Mapping
+
+| Protocol | Method Semantics | `SwapMode` | `FixedAmount` | `LimitAmountType` | `LimitAmount` | `ActualLimitAmount` |
+| --- | --- | --- | --- | --- | --- | --- |
+| `Pump` | `buy` | `exact_out` | target token amount | `max_in` | max SOL in | actual SOL in |
+| `Pump` | `buy_exact_sol_in` | `exact_in` | SOL in | `min_out` | min token out | actual token out |
+| `Pump` | `sell` | `exact_in` | token in | `min_out` | min SOL out | actual SOL out |
+| `PumpAMM` | `buy` | `exact_out` | target base out | `max_in` | max quote in | actual quote in |
+| `PumpAMM` | `buy_exact_quote_in` | `exact_in` | quote in | `min_out` | min base out | actual base out |
+| `PumpAMM` | `sell` | `exact_in` | base in | `min_out` | min quote out | actual quote out |
+| `MeteoraDLMM` | `swap` / `swap2` / `swap_with_price_impact` | `exact_in` | `AmountIn` | `min_out` | instruction min out | event output |
+| `MeteoraDLMM` | `swap_exact_out` / `swap_exact_out2` | `exact_out` | `OutAmount` | `max_in` | `MaxInAmount` | event input |
+| `MeteoraPools` | `swap` | `exact_in` | `InAmount` | `min_out` | `MinimumOutAmount` | actual output side |
+| `MeteoraBondingCurve` | `swap` / `swap2` | `exact_in` | `AmountIn` | `min_out` | `MinimumAmountOut` | actual output side |
+| `MeteoraAmmV2` | `swap` / `swap2` exact-in or partial | `exact_in` | params input side | `min_out` | params output threshold | actual output side |
+| `MeteoraAmmV2` | `swap` / `swap2` exact-out | `exact_out` | params target output | `max_in` | params max input | actual input side |
+| `RaydiumLaunchLab` | `*_ExactIn` | `exact_in` | `Amount` | `min_out` | `OtherAmountThreshold` | actual output side |
+| `RaydiumLaunchLab` | `*_ExactOut` | `exact_out` | `Amount` | `max_in` | `OtherAmountThreshold` | actual input side |
+| `RaydiumCPMM` | `swap_base_input` | `exact_in` | `AmountIn` | `min_out` | `MinimumAmountOut` | actual output side |
+| `RaydiumCPMM` | `swap_base_output` | `exact_out` | `AmountOut` | `max_in` | `MaxAmountIn` | actual input side |
+| `RaydiumCLMM` | `swap` / `swap_v2` | `exact_in` or `exact_out` | `amount` | `min_out` or `max_in` | `other_amount_threshold` | opposite-side actual amount |
+| `RaydiumV4` | `swap_base_in` / `swap_base_in_v2` | `exact_in` | `amount_in` | `min_out` | `minimum_amount_out` | actual output side |
+| `RaydiumV4` | `swap_base_out` / `swap_base_out_v2` | `exact_out` | `amount_out` | `max_in` | `max_amount_in` | actual input side |
+| `OrcaWhirlpool` | `swap` / `swap_v2` | `exact_in` or `exact_out` | `amount` | `min_out` or `max_in` | `other_amount_threshold` | opposite-side actual amount |
+| `OrcaWhirlpool` | `two_hop_swap` / `two_hop_swap_v2` | route-level | route specified amount | `min_out` or `max_in` | route threshold | route final output or total input |
+
+## Notes
+
+- `Pump` quote side is normalized to `wSOL` in the slippage fields, even when legacy `Swap.QuoteMint` is not populated.
+- `OrcaWhirlpool` two-hop instructions use route-level slippage. The normalized slippage fields are attached to the first returned swap entry.
+- `MeteoraAmmV2` uses `SwapMode.ExactIn`, `SwapMode.PartialFill`, and `SwapMode.ExactOut`. `PartialFill` is treated like exact-in for slippage purposes because it still uses a minimum-output threshold.
+
+## DAMM v2 Verification
+
+The `MeteoraAmmV2` mapping has been checked against the program IDL for `cpamdpZCGKUy5JxQXB4dcpGPiikHawvSWAd6mEn1sGG`.
+
+- `swap`
+  - instruction arg type: `SwapParameters`
+  - fields: `amountIn`, `minimumAmountOut`
+  - semantics: exact-in
+- `swap2`:
+  - instruction / event arg type: `SwapParameters2`
+  - `amount0`: "When it's exact in, partial fill, this will be amount_in. When it's exact out, this will be amount_out"
+  - `amount1`: "When it's exact in, partial fill, this will be minimum_amount_out. When it's exact out, this will be maximum_amount_in"
+  - `swapMode`: `ExactIn`, `PartialFill`, `ExactOut`
+
+The downloaded JSON IDL references `SwapMode` in the field docs but does not inline the enum body itself. In this repository, the raw `swapMode` values are interpreted consistently as:
+
+- `0 = ExactIn`
+- `1 = PartialFill`
+- `2 = ExactOut`
+
+That means the parser mapping is:
+
+- `swap2` + `ExactIn` / `PartialFill`
+  - `FixedAmount = amount0`
+  - `LimitAmount = amount1`
+  - `LimitAmountType = min_out`
+- `swap2` + `ExactOut`
+  - `FixedAmount = amount0`
+  - `LimitAmount = amount1`
+  - `LimitAmountType = max_in`

+
+## Tx Binary enum synchronization
+
+When adding or renaming transaction-facing enum values, keep the binary format definitions in sync.
+
+This includes, but is not limited to:
+
+- tx events
+- programs
+- platforms
+- MEV agents
+- swap modes, amount sides, limit types, and fee sides
+
+Checklist:
+
+1. Add the public constant in the normal source location, such as `enum.go`.
+2. Add any address mapping in `consts.go` when the enum is account-derived, such as platform or MEV agent detection.
+3. Append the new value to the matching versioned enum list in `tx_binary.go` under `txBinaryEnumTables`.
+4. Do not reorder or insert into existing `tx_binary.go` enum lists unless the binary version is intentionally changed; append to preserve existing numeric IDs.
+5. Add or update tx-binary round-trip coverage so encoding and decoding the new enum value is exercised.
