+# CompressibleInstruction TypeScript Implementation
+
+This document demonstrates the TypeScript equivalent of the Rust `CompressibleInstruction` module, now organized in a clean modular structure.
+
+## New Structure
+
+The compressible instruction functionality is now organized in `src/compressible/`:
+
+-   **`types.ts`** - All TypeScript types and interfaces
+-   **`layout.ts`** - Borsh schemas and serialization functions
+-   **`instruction.ts`** - Standalone functions + optional class-based API
+-   **`index.ts`** - Clean exports and utilities
+
+## Usage Examples
+
+### Import Options
+
+```typescript
+// Import everything from the compressible module
+import {
+    // Action functions (high-level, recommended)
+    initializeCompressionConfig,
+    updateCompressionConfig,
+    compressAccount,
+    decompressAccountsIdempotent,
+    // Instruction builders (low-level)
+    createInitializeCompressionConfigInstruction,
+    createUpdateCompressionConfigInstruction,
+    createCompressAccountInstruction,
+    createDecompressAccountsIdempotentInstruction,
+    CompressibleInstruction,
+    deriveCompressionConfigAddress,
+    getProgramDataAccount,
+    checkProgramUpdateAuthority,
+    createCompressedAccountData,
+    serializeInitializeCompressionConfigData,
+    COMPRESSIBLE_DISCRIMINATORS,
+} from '@lightprotocol/stateless.js/compressible';
+
+// Or import specific items from main package
+import {
+    initializeCompressionConfig,
+    createInitializeCompressionConfigInstruction,
+    deriveCompressionConfigAddress,
+    createCompressedAccountData,
+    COMPRESSIBLE_DISCRIMINATORS,
+} from '@lightprotocol/stateless.js';
+```
+
+### Initialize Compression Config (Action Function - Recommended)
+
+```typescript
+import { initializeCompressionConfig } from '@lightprotocol/stateless.js';
+import { Rpc } from '../rpc'; // or your RPC setup
+
+// High-level action function handles transaction building and sending
+const txSignature = await initializeCompressionConfig(
+    rpc,
+    payer, // Signer
+    programId, // PublicKey
+    authority, // Signer
+    compressionDelay, // number
+    rentRecipient, // PublicKey
+    addressSpace, // PublicKey[]
+    0, // configBump (optional)
+    undefined, // custom discriminator (optional)
+    confirmOptions, // ConfirmOptions (optional)
+);
+```
+
+### Initialize Compression Config (Instruction Builder)
+
+```typescript
+import {
+    createCompressibleInitializeConfigInstruction,
+    COMPRESSIBLE_DISCRIMINATORS,
+} from '@lightprotocol/stateless.js';
+import { PublicKey } from '@solana/web3.js';
+
+// Using standard discriminator - standalone function (recommended)
+const ix = createCompressibleInitializeConfigInstruction({
+    programId,
+    discriminator: COMPRESSIBLE_DISCRIMINATORS.INITIALIZE_COMPRESSION_CONFIG,
+    payer: payer.publicKey,
+    authority: authority.publicKey,
+    compressionDelay,
+    rentRecipient,
+    addressSpace,
+    configBump: 0,
+});
+
+// Using custom discriminator - standalone function
+const customDiscriminator = [1, 2, 3, 4, 5, 6, 7, 8];
+const customIx = createCompressibleInitializeConfigInstruction({
+    programId,
+    discriminator: customDiscriminator,
+    payer: payer.publicKey,
+    authority: authority.publicKey,
+    compressionDelay,
+    rentRecipient,
+    addressSpace,
+});
+```
+
+### Initialize Compression Config (Class-based API)
+
+```typescript
+import {
+    CompressibleInstruction,
+    COMPRESSIBLE_DISCRIMINATORS,
+} from '@lightprotocol/stateless.js';
+
+// Same functionality, class-based syntax
+const ix = CompressibleInstruction.initializeCompressionConfig(
+    programId,
+    COMPRESSIBLE_DISCRIMINATORS.INITIALIZE_COMPRESSION_CONFIG,
+    payer.publicKey,
+    authority.publicKey,
+    compressionDelay,
+    rentRecipient,
+    addressSpace,
+    0, // configBump
+);
+```
+
+### Update Compression Config (Action Function - Recommended)
+
+```typescript
+import { updateCompressionConfig } from '@lightprotocol/stateless.js';
+
+// High-level action function
+const txSignature = await updateCompressionConfig(
+    rpc,
+    payer, // Signer
+    programId, // PublicKey
+    authority, // Signer
+    newCompressionDelay, // number | null
+    newRentRecipient, // PublicKey | null
+    newAddressSpace, // PublicKey[] | null
+    newUpdateAuthority, // PublicKey | null
+    undefined, // custom discriminator (optional)
+    confirmOptions, // ConfirmOptions (optional)
+);
+```
+
+### Update Compression Config (Instruction Builder)
+
+```typescript
+import {
+    createUpdateCompressionConfigInstruction,
+    COMPRESSIBLE_DISCRIMINATORS,
+} from '@lightprotocol/stateless.js';
+
+// Low-level instruction builder
+const updateIx = createUpdateCompressionConfigInstruction(
+    programId,
+    COMPRESSIBLE_DISCRIMINATORS.UPDATE_COMPRESSION_CONFIG,
+    authority.publicKey,
+    newCompressionDelay,
+    newRentRecipient,
+    newAddressSpace,
+    newUpdateAuthority,
+);
+
+// Class-based alternative
+const updateIx2 = CompressibleInstruction.updateCompressionConfig(
+    programId,
+    COMPRESSIBLE_DISCRIMINATORS.UPDATE_COMPRESSION_CONFIG,
+    authority.publicKey,
+    newCompressionDelay,
+    newRentRecipient,
+    newAddressSpace,
+    newUpdateAuthority,
+);
+```
+
+### Compress Account
+
+```typescript
+import { createCompressAccountInstruction } from '@lightprotocol/stateless.js';
+
+// Standalone function (recommended)
+const compressIx = createCompressAccountInstruction({
+    programId,
+    discriminator: [1, 2, 3, 4, 5, 6, 7, 8], // custom discriminator
+    payer: payer.publicKey,
+    pdaToCompress,
+    rentRecipient,
+    compressedAccountMeta,
+    validityProof,
+    systemAccounts,
+});
+```
+
+### Decompress Accounts Idempotent
+
+```typescript
+import * as borsh from '@coral-xyz/borsh';
+import {
+    createDecompressAccountsIdempotentInstruction,
+    COMPRESSIBLE_DISCRIMINATORS,
+} from '@lightprotocol/stateless.js';
+
+// Define your program-specific data schema
+const MyDataSchema = borsh.struct([
+    borsh.u64('amount'),
+    borsh.publicKey('mint'),
+    // ... other fields
+]);
+
+type MyData = {
+    amount: BN;
+    mint: PublicKey;
+    // ... other fields
+};
+
+// Standalone function (recommended)
+const decompressIx = createDecompressAccountsIdempotentInstruction<MyData>({
+    programId,
+    discriminator: COMPRESSIBLE_DISCRIMINATORS.DECOMPRESS_ACCOUNTS_IDEMPOTENT,
+    feePayer: feePayer.publicKey,
+    rentPayer: rentPayer.publicKey,
+    solanaAccounts,
+    compressedAccountsData,
+    bumps,
+    validityProof,
+    systemAccounts,
+    dataSchema: MyDataSchema, // Required for proper serialization
+});
+
+// Class-based alternative
+const decompressIx2 =
+    CompressibleInstruction.decompressAccountsIdempotent<MyData>(
+        programId,
+        COMPRESSIBLE_DISCRIMINATORS.DECOMPRESS_ACCOUNTS_IDEMPOTENT,
+        feePayer.publicKey,
+        rentPayer.publicKey,
+        solanaAccounts,
+        compressedAccountsData,
+        bumps,
+        validityProof,
+        systemAccounts,
+        MyDataSchema,
+    );
+```
+
+## Helper Utilities
+
+### Direct Imports (Recommended)
+
+```typescript
+import {
+    createCompressedAccountData,
+    deriveCompressionConfigAddress,
+    getProgramDataAccount,
+    checkProgramUpdateAuthority,
+    COMPRESSIBLE_DISCRIMINATORS,
+} from '@lightprotocol/stateless.js';
+
+// Create compressed account data
+const compressedAccountData = createCompressedAccountData(
+    compressedAccount,
+    myDataVariant,
+    seeds,
+    outputStateTreeIndex,
+);
+
+// Derive compression config PDA
+const [configPda, bump] = deriveCompressionConfigAddress(programId, 0);
+
+// Get program data account for authority validation
+const { programDataAddress, programDataAccountInfo } =
+    await getProgramDataAccount(programId, connection);
+
+// Check program update authority
+checkProgramUpdateAuthority(programDataAccountInfo, authority);
+
+// Access standard discriminators
+const discriminators = COMPRESSIBLE_DISCRIMINATORS;
+```
+
+### Class-Based API (Alternative)
+
+```typescript
+import { CompressibleInstruction } from '@lightprotocol/stateless.js';
+
+// Create compressed account data using class method
+const compressedAccountData =
+    CompressibleInstruction.createCompressedAccountData(
+        compressedAccount,
+        myDataVariant,
+        seeds,
+        outputStateTreeIndex,
+    );
+
+// Derive compression config PDA using class method
+const [configPda, bump] =
+    CompressibleInstruction.deriveCompressionConfigAddress(programId, 0);
+
+// Get program data account using class method
+const { programDataAddress, programDataAccountInfo } =
+    await CompressibleInstruction.getProgramDataAccount(programId, connection);
+
+// Check program update authority using class method
+CompressibleInstruction.checkProgramUpdateAuthority(
+    programDataAccountInfo,
+    authority,
+);
+
+// Access discriminators via class constant
+const discriminators = CompressibleInstruction.DISCRIMINATORS;
+
+// Serialize config data using class method
+const serializedData =
+    CompressibleInstruction.serializeInitializeCompressionConfigData(
+        compressionDelay,
+        rentRecipient,
+        addressSpace,
+        configBump,
+    );
+```
+
+### Complete Workflow Example (Class-Based)
+
+```typescript
+import { CompressibleInstruction } from '@lightprotocol/stateless.js';
+import { Connection, PublicKey } from '@solana/web3.js';
+
+// All utilities available through one class
+const programId = new PublicKey('...');
+const connection = new Connection('...');
+const authority = new PublicKey('...');
+
+// Use class constants
+const discriminator =
+    CompressibleInstruction.DISCRIMINATORS.INITIALIZE_COMPRESSION_CONFIG;
+
+// Use class utilities
+const [configPda, bump] =
+    CompressibleInstruction.deriveCompressionConfigAddress(programId);
+const { programDataAddress, programDataAccountInfo } =
+    await CompressibleInstruction.getProgramDataAccount(programId, connection);
+
+// Validate authority using class method
+CompressibleInstruction.checkProgramUpdateAuthority(
+    programDataAccountInfo,
+    authority,
+);
+
+// Create instruction using class method
+const ix = CompressibleInstruction.initializeCompressionConfig(
+    programId,
+    discriminator,
+    payer.publicKey,
+    authority,
+    compressionDelay,
+    rentRecipient,
+    addressSpace,
+    bump,
+);
+
+// Create compressed account data using class method
+const compressedData = CompressibleInstruction.createCompressedAccountData(
+    compressedAccount,
+    myAccountData,
+    seeds,
+    outputStateTreeIndex,
+);
+```
+
+## Type Definitions
+
+### Core Types
+
+```typescript
+// Generic compressed account data for any program
+type CompressedAccountData<T> = {
+    meta: CompressedAccountMeta;
+    data: T; // Program-specific variant
+    seeds: Uint8Array[]; // PDA seeds without bump
+};
+
+// Instruction data for decompress idempotent
+type DecompressMultipleAccountsIdempotentData<T> = {
+    proof: ValidityProof;
+    compressedAccounts: CompressedAccountData<T>[];
+    bumps: number[];
+    systemAccountsOffset: number;
+};
+
+// Update config instruction data
+type UpdateCompressionConfigData = {
+    newCompressionDelay: number | null;
+    newRentRecipient: PublicKey | null;
+    newAddressSpace: PublicKey[] | null;
+    newUpdateAuthority: PublicKey | null;
+};
+```
+
+### Borsh Schemas
+
+```typescript
+// Create custom schemas for your data types
+export function createCompressedAccountDataSchema<T>(
+    dataSchema: borsh.Layout<T>,
+): borsh.Layout<CompressedAccountData<T>>;
+
+export function createDecompressMultipleAccountsIdempotentDataSchema<T>(
+    dataSchema: borsh.Layout<T>,
+): borsh.Layout<DecompressMultipleAccountsIdempotentData<T>>;
+```
+
+## Key Features
+
+1. **Clean Modular Structure**: Organized in `src/compressible/` with clear separation of concerns
+2. **Dual API Design**: Both standalone functions (recommended) and class-based API
+3. **Generic Type Support**: Works with any program-specific compressed account variant
+4. **Custom Discriminators**: Always allows custom instruction discriminator bytes
+5. **Borsh Serialization**: Uses `@coral-xyz/borsh` instead of Anchor dependency
+6. **Solana SDK Patterns**: Follows patterns like `SystemProgram.transfer()`
+7. **Type Safety**: Full TypeScript support with proper type checking
+8. **Error Handling**: Comprehensive validation and error messages
+9. **Tree Exports**: Clean imports from both main package and sub-modules

+
+## API Philosophy
+
+-   **Action Functions**: Highest-level API. Handle RPC connection, transaction building, signing, and sending. Most convenient for applications.
+-   **Instruction Builders**: Mid-level API. Build individual `TransactionInstruction` objects. Good for custom transaction composition.
+-   **Utility Functions**: Helper functions for common operations like PDA derivation, account data creation, and authority validation.
+-   **Class-based API**: Complete alternative providing instruction builders, utilities, and constants through static methods. Familiar for teams migrating from other SDKs.
+
+### Recommendation
+
+1. **Use Action Functions** for most applications - they handle all the complexity
+2. **Use Direct Utility Imports** for specific helper functions - clean and tree-shakeable
+3. **Use Instruction Builders** when you need custom transaction composition or advanced control
+4. **Use Class-based API** if your team prefers centralized class patterns or needs a single import
+
+### API Styles
+
+```typescript
+// Direct imports (recommended for modern TS/JS)
+import {
+    initializeCompressionConfig,
+    deriveCompressionConfigAddress,
+} from '@lightprotocol/stateless.js';
+
+// Class-based (alternative, all-in-one)
+import { CompressibleInstruction } from '@lightprotocol/stateless.js';
+const config =
+    CompressibleInstruction.deriveCompressionConfigAddress(programId);
+```
+
+The TypeScript implementation provides equivalent functionality to Rust while maintaining TypeScript idioms and patterns in a clean, modular structure.

+# Token 2022 Metadata Pointer Extension Analysis
+
+## Overview
+The Token 2022 metadata pointer extension provides a mechanism for SPL Token 2022 mints to reference metadata accounts using a **Type-Length-Value (TLV)** encoding system. This allows metadata to be stored either directly in the mint account or pointed to external metadata accounts.
+
+## Core Architecture
+
+### 1. MetadataPointer Extension Structure
+```rust
+#[repr(C)]
+#[derive(Clone, Copy, Debug, Default, PartialEq, Pod, Zeroable)]
+pub struct MetadataPointer {
+    /// Authority that can set the metadata address
+    pub authority: OptionalNonZeroPubkey,
+    /// Account address that holds the metadata
+    pub metadata_address: OptionalNonZeroPubkey,
+}
+```
+
+### 2. TLV Extension System
+Extensions are stored using TLV format:
+- **Type**: 2 bytes (ExtensionType enum)
+- **Length**: 2 bytes (data length)
+- **Value**: Variable length data
+
+Account layout:
+```
+[Base Mint: 82 bytes][Padding: 83 bytes][Account Type: 1 byte][TLV Extensions...]
+```
+
+### 3. Extension Types
+- `MetadataPointer`: Points to metadata account
+- `TokenMetadata`: Contains metadata directly
+- Extensions are parsed sequentially through TLV data
+
+## Token 2022 Metadata Account Structure
+
+The account that a `MetadataPointer` points to contains the actual `TokenMetadata` stored in a **TLV (Type-Length-Value)** format. Here's the detailed structure:
+
+### Account Layout
+
+```
+┌─────────────────────────────────────────────────────────────────┐
+│                    Complete Account Structure                    │
+├─────────────────────────────────────────────────────────────────┤
+│ Base Mint Data (82 bytes)                                       │
+│ ┌─ supply: u64                                                  │
+│ ├─ decimals: u8                                                 │
+│ ├─ is_initialized: bool                                         │
+│ ├─ freeze_authority: Option<Pubkey>                             │
+│ └─ mint_authority: Option<Pubkey>                               │
+├─────────────────────────────────────────────────────────────────┤
+│ Extension Data (Variable Length)                                │
+│                                                                 │
+│ ┌─ MetadataPointer Extension (TLV Entry)                        │
+│ │ ├─ Type: ExtensionType::MetadataPointer (2 bytes)             │
+│ │ ├─ Length: 64 (4 bytes)                                       │
+│ │ └─ Value: MetadataPointer struct (64 bytes)                   │
+│ │   ├─ authority: OptionalNonZeroPubkey (32 bytes)              │
+│ │   └─ metadata_address: OptionalNonZeroPubkey (32 bytes)       │
+│ │                                                               │
+│ └─ TokenMetadata Extension (TLV Entry)                          │
+│   ├─ Type: ExtensionType::TokenMetadata (2 bytes)               │
+│   ├─ Length: Variable (4 bytes)                                 │
+│   └─ Value: Borsh-serialized TokenMetadata                      │
+│     ├─ update_authority: OptionalNonZeroPubkey (32 bytes)       │
+│     ├─ mint: Pubkey (32 bytes)                                  │
+│     ├─ name: String (4 bytes length + data)                     │
+│     ├─ symbol: String (4 bytes length + data)                   │
+│     ├─ uri: String (4 bytes length + data)                      │
+│     └─ additional_metadata: Vec<(String, String)>               │
+│       └─ (4 bytes count + entries)                              │
+└─────────────────────────────────────────────────────────────────┘
+```
+
+### TokenMetadata Structure Details
+
+```rust
+#[derive(Clone, Debug, Default, PartialEq, BorshDeserialize, BorshSerialize)]
+pub struct TokenMetadata {
+    /// Authority that can update the metadata
+    pub update_authority: OptionalNonZeroPubkey,
+    /// Associated mint (prevents spoofing)
+    pub mint: Pubkey,
+    /// Token name (e.g., "Solana Token")
+    pub name: String,
+    /// Token symbol (e.g., "SOL")
+    pub symbol: String,
+    /// URI to external metadata JSON
+    pub uri: String,
+    /// Additional key-value pairs
+    pub additional_metadata: Vec<(String, String)>,
+}
+```
+
+### Two Storage Patterns
+
+#### Pattern 1: Self-Referential (Common)
+```
+Mint Account (Same Account)
+├─ MetadataPointer Extension
+│  └─ metadata_address: [points to same account]
+└─ TokenMetadata Extension
+   └─ [actual metadata data]
+```
+
+#### Pattern 2: External Account
+```
+Mint Account                    External Metadata Account
+├─ MetadataPointer Extension    ├─ TokenMetadata Extension
+│  └─ metadata_address ────────→│  └─ [actual metadata data]
+└─ [no TokenMetadata]           └─ [account owned by token program]
+```
+
+### Serialization Format
+
+The `TokenMetadata` is serialized using **Borsh** format:
+- **Discriminator**: `[112, 132, 90, 90, 11, 88, 157, 87]` (not stored in account)
+- **Variable Length**: Strings and Vec fields make the size dynamic
+- **TLV Wrapper**: Type + Length headers allow efficient parsing
+
+## Key Functions
+
+### Metadata Creation Process
+1. **Initialize MetadataPointer**: Set authority and metadata address
+2. **Create/Update Metadata**: Store metadata in referenced account
+3. **Authority Validation**: Ensure proper permissions for updates
+
+### Extension Parsing
+- Sequential TLV parsing using `get_tlv_indices()`
+- Type-based lookup for specific extensions
+- Support for both fixed-size (Pod) and variable-length extensions
+
+## Integration with Compressed Token Mint
+
+### Current Implementation Analysis
+Your compressed token mint in `programs/compressed-token/program/src/mint/state.rs`:
+
+```rust
+pub struct CompressedMint {
+    pub spl_mint: Pubkey,
+    pub supply: u64,
+    pub decimals: u8,
+    pub is_decompressed: bool,
+    pub mint_authority: Option<Pubkey>,
+    pub freeze_authority: Option<Pubkey>,
+    pub num_extensions: u8,  // ← Already supports extensions!
+}
+```
+
+### Integration Recommendations
+
+#### 1. **Extension Data Structure**
+Add metadata pointer extension to your compressed mint:
+
+```rust
+#[derive(Debug, Clone, BorshSerialize, BorshDeserialize)]
+pub struct CompressedMintMetadataPointer {
+    pub authority: Option<Pubkey>,
+    pub metadata_address: Option<Pubkey>,
+}
+
+// Add to extension system
+pub enum CompressedMintExtension {
+    MetadataPointer(CompressedMintMetadataPointer),
+    // Other extensions...
+}
+```
+
+#### 2. **Hashing Integration**
+The metadata pointer would need to be included in the hash calculation:
+
+```rust
+// In hash_with_hashed_values, add metadata pointer handling
+if let Some(metadata_pointer) = metadata_pointer_extension {
+    // Hash metadata pointer data
+    let metadata_pointer_bytes = [0u8; 32];
+    // Set prefix for metadata pointer
+    metadata_pointer_bytes[30] = 4; // metadata_pointer prefix
+    // Include in hash_inputs
+}
+```
+
+#### 3. **Processing Integration**
+Update `process_create_compressed_mint` to handle metadata pointer:
+
+```rust
+// In processor.rs, add metadata pointer initialization
+if let Some(metadata_pointer_data) = parsed_instruction_data.metadata_pointer {
+    // Validate metadata pointer authority
+    // Set metadata address
+    // Update num_extensions count
+}
+```
+
+### Key Considerations
+
+#### 1. **Compression-Specific Challenges**
+- **Hash State**: Metadata pointer must be included in compressed account hash
+- **Proof Generation**: Changes to metadata pointer affect merkle tree proofs
+- **Extension Counting**: `num_extensions` field needs proper management
+
+#### 2. **Authority Model**
+- Metadata pointer authority separate from mint authority
+- Authority validation needed for metadata updates
+- Consider compressed account ownership model
+
+#### 3. **Storage Efficiency**
+- Compressed accounts store data efficiently
+- Metadata pointer adds minimal overhead (64 bytes)
+- Consider storing metadata directly vs. pointer for small metadata
+
+### Implementation Steps
+
+1. **Define Extension Types**: Create compressed mint extension enum
+2. **Update State Structure**: Add extension parsing to CompressedMint
+3. **Modify Hash Function**: Include extensions in hash calculation
+4. **Update Instructions**: Add metadata pointer initialization/update
+5. **Authority Validation**: Implement permission checks
+6. **Testing**: Ensure compatibility with existing compressed token functionality
+
+## Account Reading Process
+
+```rust
+// 1. Load account data
+let buffer = account_info.try_borrow_data()?;
+
+// 2. Parse as mint with extensions
+let mint = PodStateWithExtensions::<PodMint>::unpack(&buffer)?;
+
+// 3. Get metadata pointer
+let metadata_pointer = mint.get_extension::<MetadataPointer>()?;
+
+// 4. If self-referential, read metadata from same account
+if metadata_pointer.metadata_address == Some(mint_pubkey) {
+    let metadata = mint.get_variable_len_extension::<TokenMetadata>()?;
+}
+```
+
+## Summary
+
+The Token 2022 metadata pointer extension is well-designed for integration with compressed tokens, requiring mainly adaptation of the TLV parsing logic and hash computation for the compressed account model. The metadata account structure is designed for flexibility, allowing metadata to be stored either directly in the mint account or in a separate dedicated account, while maintaining efficient TLV parsing and Borsh serialization.

+This file demonstrates the complete enum support for the ZeroCopy derive macro.
+
+## What gets generated:
+
+For this enum:
+```rust
+#[derive(ZeroCopy)]
+pub enum Action {
+    MintTo(MintToAction),
+    Update,
+    CreateSplMint,
+    UpdateMetadata,
+}
+```
+
+The macro generates:
+```rust
+#[derive(Debug, Clone, PartialEq)]
+pub enum ZAction<'a> {
+    MintTo(ZMintToAction<'a>),  // Concrete type for pattern matching
+    Update,
+    CreateSplMint,
+    UpdateMetadata,
+}
+
+impl<'a> Deserialize<'a> for Action {
+    type Output = ZAction<'a>;
+    
+    fn zero_copy_at(data: &'a [u8]) -> Result<(Self::Output, &'a [u8]), ZeroCopyError> {
+        match data[0] {
+            0 => {
+                let (value, bytes) = MintToAction::zero_copy_at(&data[1..])?;
+                Ok((ZAction::MintTo(value), bytes))
+            }
+            1 => Ok((ZAction::Update, &data[1..])),
+            2 => Ok((ZAction::CreateSplMint, &data[1..])),

+            _ => Err(ZeroCopyError::InvalidConversion),
+        }
+    }
+}
+```
+
+## Usage:
+
+```rust
+for action in parsed_instruction_data.actions.iter() {
+    match action {
+        ZAction::MintTo(mint_action) => {
+            // Access mint_action.amount, mint_action.recipient, etc.

+This approach:
+- ✅ Avoids import issues (uses qualified syntax in type alias)
+- ✅ Enables pattern matching (concrete types via aliases)  
+- ✅ Maintains type safety (proper Deserialize trait usage)

+## Error Code Reference
+
+| Error Code | Error Name | Description | Common Fix |
+|------------|------------|-------------|------------|
+| 16031 | `CpiAccountsIndexOutOfBounds` | Missing account in accounts array | Add signer with `add_pre_accounts_signer_mut()` |
+| 6020 | `CpiContextAccountUndefined` | CPI context expected but not provided | Set `cpi_context: None` for simple operations |
+
+### Light System Program Errors (Full Reference)
+| 6017 | `ProofIsNone` | 6018 | `ProofIsSome` | 6019 | `EmptyInputs` | 6020 | `CpiContextAccountUndefined` |
+| 6021 | `CpiContextEmpty` | 6022 | `CpiContextMissing` | 6023 | `DecompressionRecipientDefined` |
+
+## Common Issues and Solutions
+
+### 1. `CpiAccountsIndexOutOfBounds` (Error 16031)
+Missing signer account. **Fix**: `remaining_accounts.add_pre_accounts_signer_mut(payer.pubkey())`
+
+### 2. Privilege Escalation Error
+Manually adding accounts instead of using PackedAccounts. **Fix**: Use `add_pre_accounts_signer_mut()` instead of manual account concatenation.
+
+### 3. Account Structure Mismatch
+Wrong context type. **Fix**: Use `Generic<'info>` for single signer, `GenericWithAuthority<'info>` for signer + authority.
+
+### 4. `CpiContextAccountUndefined` (Error 6020)
+**Root Cause**: Using functions designed for CPI context when you don't need it.
+
+**CPI Context Purpose**: Optimize multi-program transactions by using one proof instead of multiple. Flow:
+1. First program: Cache signer checks in CPI context
+2. Second program: Read context, combine data, execute with single proof
+
+**Solutions**:
+```rust
+// ✅ Simple operations - no CPI context
+let cpi_inputs = CpiInputs {
+    proof,
+    account_infos: Some(vec![account.to_account_info().unwrap()]),
+    new_addresses: Some(vec![new_address_params]),
+    cpi_context: None, // ← Key
+    ..Default::default()
+};
+
+// ✅ Complex multi-program operations - use CPI context  
+let config = SystemAccountMetaConfig::new_with_cpi_context(program_id, cpi_context_account);
+```
+
+### 5. Avoid Complex Function Reuse
+**Problem**: Functions like `process_create_compressed_account` expect CPI context setup.
+
+**Fix**: Use direct Light SDK approach:
+```rust
+// ❌ Complex function with CPI context dependency
+process_create_compressed_account(...)
+
+// ✅ Direct approach
+let mut account = LightAccount::<'_, CompressedEscrowPda>::new_init(&crate::ID, Some(address), tree_index);
+account.amount = amount;
+account.owner = *cpi_accounts.fee_payer().key;
+let cpi_inputs = CpiInputs { proof, account_infos: Some(vec![account.to_account_info().unwrap()]), cpi_context: None, ..Default::default() };
+cpi_inputs.invoke_light_system_program(cpi_accounts)
+```
+
+### 6. Critical Four Invokes Implementation Learnings
+
+**CompressInputs Structure for CPI Context Operations**:
+```rust
+let compress_inputs = CompressInputs {
+    fee_payer: *cpi_accounts.fee_payer().key,
+    authority: *cpi_accounts.fee_payer().key,
+    mint,
+    recipient,
+    sender_token_account: *remaining_accounts[0].key, // ← Use remaining_accounts index
+    amount,
+    output_tree_index,
+    // ❌ Wrong: output_queue_pubkey: *cpi_accounts.tree_accounts().unwrap()[0].key,
+    token_pool_pda: *remaining_accounts[1].key, // ← From remaining_accounts
+    transfer_config: Some(TransferConfig {
+        cpi_context: Some(CompressedCpiContext {
+            set_context: true,
+            first_set_context: true,
+            cpi_context_account_index: 0,
+        }),
+        cpi_context_pubkey: Some(cpi_context_pubkey),
+        ..Default::default()
+    }),
+    spl_token_program: *remaining_accounts[2].key, // ← SPL_TOKEN_PROGRAM_ID
+    tree_accounts: cpi_accounts.tree_pubkeys().unwrap(), // ← From CPI accounts
+};
+```
+
+**Critical Account Ordering for Four Invokes**:
+```rust
+// Test setup - exact order matters for remaining_accounts indices
+remaining_accounts.add_pre_accounts_signer_mut(payer.pubkey());
+// Remaining accounts 0 - compression token account
+remaining_accounts.add_pre_accounts_meta(AccountMeta::new(compression_token_account, false));
+// Remaining accounts 1 - token pool PDA
+remaining_accounts.add_pre_accounts_meta(AccountMeta::new(token_pool_pda1, false));
+// Remaining accounts 2 - SPL token program
+remaining_accounts.add_pre_accounts_meta(AccountMeta::new(SPL_TOKEN_PROGRAM_ID.into(), false));
+// Remaining accounts 3 - compressed token program
+remaining_accounts.add_pre_accounts_meta(AccountMeta::new(compressed_token_program, false));
+// Remaining accounts 4 - CPI authority PDA
+remaining_accounts.add_pre_accounts_meta(AccountMeta::new(cpi_authority_pda, false));
+```
+
+**Validity Proof and Tree Info Management**:
+```rust
+// Get escrow account directly by address (more efficient)
+let escrow_account = rpc.get_compressed_account(escrow_address, None).await?.value;
+
+// Pack tree infos BEFORE constructing TokenAccountMeta
+let packed_tree_info = rpc_result.pack_tree_infos(&mut remaining_accounts);
+
+// Use correct tree info indices for each compressed account
+let mint2_tree_info = packed_tree_info.state_trees.as_ref().unwrap().packed_tree_infos[1];
+let mint3_tree_info = packed_tree_info.state_trees.as_ref().unwrap().packed_tree_infos[2];
+let escrow_tree_info = packed_tree_info.state_trees.as_ref().unwrap().packed_tree_infos[0];
+```
+
+**System Accounts Start Offset**:
+```rust
+// Use the actual offset returned by to_account_metas()
+let (accounts, system_accounts_start_offset, _) = remaining_accounts.to_account_metas();
+// Pass this offset to the instruction
+system_accounts_start_offset: system_accounts_start_offset as u8,
+```
+
+## Best Practices
+
+### CPI Context Decision
+- **Use**: Multi-program transactions with compressed accounts (saves proofs)
+- **Avoid**: Simple single-program operations (PDA creation, basic transfers)
+
+### Account Management
+- Use `PackedAccounts` and `add_pre_accounts_signer_mut()`
+- Choose `Generic<'info>` (1 account) vs `GenericWithAuthority<'info>` (2 accounts)
+- Set `cpi_context: None` for simple operations
+
+### Working Patterns
+```rust
+// Compress tokens pattern
+let mut remaining_accounts = PackedAccounts::default();
+remaining_accounts.add_pre_accounts_signer_mut(payer.pubkey());
+let metas = get_transfer_instruction_account_metas(config);
+remaining_accounts.add_pre_accounts_metas(metas.as_slice());
+let output_tree_index = rpc.get_random_state_tree_info().unwrap().pack_output_tree_index(&mut remaining_accounts).unwrap();
+
+// Test flow: Setup → Compress → Create PDA → Execute
+```
+
+## Implementation Status
+
+### ✅ Working Features
+1. **Basic PDA Creation**: `create_escrow_pda` instruction works correctly
+2. **Token Compression**: Individual token compression operations work  
+3. **Four Invokes Instruction**: Complete CPI context implementation working
+   - Account structure: Uses `Generic<'info>` (single signer)
+   - CPI context: Proper multi-program proof optimization 
+   - Token accounts: Correct account ordering and tree info management
+   - Compress CPI: Working with proper `CompressInputs` structure
+   - Transfer CPI: Custom `transfer_tokens_with_cpi_context` wrapper replaces `transfer_tokens_to_escrow_pda`
+4. **Error Handling**: Comprehensive error code documentation and fixes
+
+### Key Implementation Success
+The `four_invokes` instruction successfully demonstrates the complete CPI context pattern for Light Protocol, enabling:
+- **Single Proof Optimization**: One validity proof for multiple compressed account operations
+- **Cross-Program Integration**: Token program + system program coordination  
+- **Production Ready**: Complete account setup and tree info management
+- **Custom Transfer Wrapper**: Purpose-built transfer function for four invokes instruction

+# Changelog
+
+## [Unreleased]
+
+### Changed
+
+- **BREAKING**: `add_compressible_instructions` macro no longer generates `create_*` instructions:
+  - Removed automatic generation of `create_user_record`, `create_game_session`, etc.
+  - Developers must implement their own create instructions with custom initialization logic
+  - This change recognizes that create instructions typically need custom business logic
+- Updated `add_compressible_instructions` macro to align with new SDK patterns:
+  - Now generates `create_compression_config` and `update_compression_config` instructions
+  - Uses `HasCompressionInfo` trait instead of deprecated `CompressionTiming`
+  - `compress_*` instructions validate against config rent recipient
+  - `decompress_multiple_pdas` now accepts seeds in `CompressedAccountData`
+  - All generated instructions follow the pattern used in `anchor-compressible`
+  - Automatically uses Anchor's `INIT_SPACE` for account size calculation (no manual SIZE needed)
+
+### Added
+
+- **MAJOR**: Enhanced external file module support:
+  - Comprehensive pattern matching for common AMM/DEX structures (PoolState, Vault, Position, etc.)
+  - Explicit seed specification syntax: `#[add_compressible_instructions(PoolState@[POOL_SEED.as_bytes(), amm_config.key().as_ref()])]`
+  - Improved import detection for `pub use` statements and CamelCase account structs
+  - Intelligent seed inference for 7+ common DeFi patterns (pools, vaults, positions, configs, etc.)
+  - Enhanced error messages with debugging info and actionable solutions
+  - Support for complex multi-file project structures like Raydium CP-Swap
+- Config management support in generated code:
+  - `CreateCompressibleConfig` accounts struct
+  - `UpdateCompressibleConfig` accounts struct
+  - Automatic config validation in create/compress instructions
+- `CompressedAccountData` now includes `seeds` field for flexible PDA derivation
+- Generated error codes for config validation
+- `CompressionInfo` now implements `anchor_lang::Space` trait for automatic size calculation
+
+### Fixed
+
+- External file module parsing that previously threw "External file modules require explicit seed definitions"
+- Import resolution for `pub use` statements across multiple files
+- Pattern detection for account structs with various naming conventions
+
+### Removed
+
+- Deprecated `CompressionTiming` trait support
+- Hardcoded constants (RENT_RECIPIENT, ADDRESS_SPACE, COMPRESSION_DELAY)
+- Manual SIZE constant requirement - now uses Anchor's built-in space calculation
+
+## Migration Guide
+
+1. **Implement your own create instructions** (macro no longer generates them):
+
+   ```rust
+   #[derive(Accounts)]
+   pub struct CreateUserRecord<'info> {
+       #[account(mut)]
+       pub user: Signer<'info>,
+       #[account(
+           init,
+           payer = user,
+           space = 8 + UserRecord::INIT_SPACE,
+           seeds = [b"user_record", user.key().as_ref()],
+           bump,
+       )]
+       pub user_record: Account<'info, UserRecord>,
+       pub system_program: Program<'info, System>,
+   }
+
+   pub fn create_user_record(ctx: Context<CreateUserRecord>, name: String) -> Result<()> {
+       let user_record = &mut ctx.accounts.user_record;
+       user_record.compression_info = CompressionInfo::new_decompressed()?;
+       user_record.owner = ctx.accounts.user.key();
+       user_record.name = name;
+       user_record.score = 0;
+       Ok(())
+   }
+   ```
+
+2. Update account structs to use `CompressionInfo` field and derive `InitSpace`:
+
+   ```rust
+   #[derive(Debug, LightHasher, LightDiscriminator, Default, InitSpace)]
+   #[account]
+   pub struct UserRecord {
+       #[skip]
+       pub compression_info: CompressionInfo,
+       #[hash]
+       pub owner: Pubkey,
+       #[max_len(32)]  // Required for String fields
+       pub name: String,
+       pub score: u64,
+   }
+   ```
+
+3. Implement `HasCompressionInfo` trait instead of `CompressionTiming`
+
+4. Create config after program deployment:
+
+   ```typescript
+   await program.methods
+     .createCompressibleConfig(compressionDelay, rentRecipient, addressSpace)
+     .rpc();
+   ```
+
+5. Update client code to use new instruction names:
+   - `create_record` → `create_user_record` (based on struct name)
+   - Pass entire struct data instead of individual fields

+/// * `config_bump` - Config bump seed (must be 0 for now)

+/// * `system_program` - System program
+/// * `program_id` - The program that owns the config
+///
+/// # Required Validation (must be done by caller)
+/// The caller MUST validate that the signer is the program's upgrade authority
+/// by checking against the program data account. This cannot be done in the SDK
+/// due to dependency constraints.

+# Example: Using the add_compressible_instructions Macro
+
+This example shows how to use the `add_compressible_instructions` macro to automatically generate compression-related instructions for your Anchor program.
+
+## Basic Setup
+
+```rust
+use anchor_lang::prelude::*;
+use light_sdk::{
+    compressible::{CompressionInfo, HasCompressionInfo},
+    derive_light_cpi_signer, LightDiscriminator, LightHasher,
+};
+use light_sdk_macros::add_compressible_instructions;
+
+declare_id!("YourProgramId11111111111111111111111111111");
+
+// Define your CPI signer
+pub const LIGHT_CPI_SIGNER: CpiSigner =
+    derive_light_cpi_signer!("YourCpiSignerPubkey11111111111111111111111");
+
+// Apply the macro to your program module
+#[add_compressible_instructions(UserRecord, GameSession)]
+#[program]
+pub mod my_program {
+    use super::*;
+
+    // The macro automatically generates these instructions:
+    // - create_compression_config (config management)
+    // - update_compression_config (config management)
+    // - compress_user_record (compress existing PDA)
+    // - compress_game_session (compress existing PDA)
+    // - decompress_multiple_pdas (decompress compressed accounts)
+    //
+    // NOTE: create_user_record and create_game_session are NOT generated
+    // because they typically need custom initialization logic
+
+    // You can still add your own custom instructions here
+}
+```
+
+## Define Your Account Structures
+
+```rust
+#[derive(Debug, LightHasher, LightDiscriminator, Default)]
+#[account]
+pub struct UserRecord {
+    #[skip]  // Skip compression_info from hashing
+    pub compression_info: CompressionInfo,
+    #[hash]  // Include in hash
+    pub owner: Pubkey,
+    #[hash]
+    pub name: String,
+    pub score: u64,
+}
+
+// Implement the required trait
+impl HasCompressionInfo for UserRecord {
+    fn compression_info(&self) -> &CompressionInfo {
+        &self.compression_info
+    }
+
+    fn compression_info_mut(&mut self) -> &mut CompressionInfo {
+        &mut self.compression_info
+    }
+}
+```
+
+## Generated Instructions
+
+### 1. Config Management
+
+```typescript
+// Create config (only program upgrade authority can call)
+await program.methods
+  .createCompressibleConfig(
+    100, // compression_delay
+    rentRecipient,
+    [addressSpace] // Now accepts an array of address trees (1-4 allowed)
+  )
+  .accounts({
+    payer: wallet.publicKey,
+    config: configPda,
+    programData: programDataPda,
+    authority: upgradeAuthority,
+    systemProgram: SystemProgram.programId,
+  })
+  .signers([upgradeAuthority])
+  .rpc();
+
+// Update config
+await program.methods
+  .updateCompressibleConfig(
+    200, // new_compression_delay (optional)
+    newRentRecipient, // (optional)
+    [newAddressSpace1, newAddressSpace2], // (optional) - array of 1-4 address trees
+    newUpdateAuthority // (optional)
+  )
+  .accounts({
+    config: configPda,
+    authority: configUpdateAuthority,
+  })
+  .signers([configUpdateAuthority])
+  .rpc();
+```
+
+### 2. Compress Existing PDA
+
+```typescript
+await program.methods
+  .compressUserRecord(proof, compressedAccountMeta)
+  .accounts({
+    user: user.publicKey,
+    pdaAccount: userRecordPda,
+    systemProgram: SystemProgram.programId,
+    config: configPda,
+    rentRecipient: rentRecipient,
+  })
+  .remainingAccounts(lightSystemAccounts)
+  .signers([user])
+  .rpc();
+```
+
+### 3. Decompress Multiple PDAs
+
+```typescript
+const compressedAccounts = [
+  {
+    meta: compressedAccountMeta1,
+    data: { userRecord: userData },
+    seeds: [Buffer.from("user_record"), user.publicKey.toBuffer()],
+  },
+  {
+    meta: compressedAccountMeta2,
+    data: { gameSession: gameData },
+    seeds: [
+      Buffer.from("game_session"),
+      sessionId.toArrayLike(Buffer, "le", 8),
+    ],
+  },
+];
+
+await program.methods
+  .decompressMultiplePdas(
+    proof,
+    compressedAccounts,
+    [userBump, gameBump], // PDA bumps
+    systemAccountsOffset
+  )
+  .accounts({
+    feePayer: payer.publicKey,
+    rentPayer: payer.publicKey,
+    systemProgram: SystemProgram.programId,
+  })
+  .remainingAccounts([
+    ...pdaAccounts, // PDAs to decompress into
+    ...lightSystemAccounts, // Light Protocol system accounts
+  ])
+  .signers([payer])
+  .rpc();
+```
+
+## Address Space Configuration
+
+The config now supports multiple address trees per address space (1-4 allowed):
+
+```typescript
+// Single address tree (backward compatible)
+const addressSpace = [addressTree1];
+
+// Multiple address trees for better scalability
+const addressSpace = [addressTree1, addressTree2, addressTree3];
+
+// When creating config
+await program.methods
+  .createCompressibleConfig(
+    100,
+    rentRecipient,
+    addressSpace // Array of 1-4 unique address tree pubkeys
+  )
+  // ... accounts
+  .rpc();
+```
+
+### Address Space Validation Rules
+
+**Create Config:**
+
+- Must contain 1-4 unique address tree pubkeys
+- No duplicate pubkeys allowed
+- All pubkeys must be valid address trees
+
+**Update Config:**
+
+- Can only **add** new address trees, never remove existing ones
+- No duplicate pubkeys allowed in the new configuration
+- Must maintain all existing address trees
+
+```typescript
+// Valid update: adding new trees
+const currentAddressSpace = [tree1, tree2];
+const newAddressSpace = [tree1, tree2, tree3]; // ✅ Valid: adds tree3
+
+// Invalid update: removing existing trees
+const invalidAddressSpace = [tree2, tree3]; // ❌ Invalid: removes tree1
+```
+
+The system validates that compressed accounts use address trees from the configured address space, providing flexibility while maintaining security and preventing accidental removal of active trees.
+
+## What You Need to Implement
+
+Since the macro only generates compression-related instructions, you need to implement:
+
+### 1. Create Instructions
+
+Implement your own create instructions for each account type:
+
+```rust
+#[derive(Accounts)]
+pub struct CreateUserRecord<'info> {
+    #[account(mut)]
+    pub user: Signer<'info>,
+    #[account(
+        init,
+        payer = user,
+        space = 8 + UserRecord::INIT_SPACE,
+        seeds = [b"user_record", user.key().as_ref()],
+        bump,
+    )]
+    pub user_record: Account<'info, UserRecord>,
+    pub system_program: Program<'info, System>,
+}
+
+pub fn create_user_record(
+    ctx: Context<CreateUserRecord>,
+    name: String,
+) -> Result<()> {
+    let user_record = &mut ctx.accounts.user_record;
+
+    // Your custom initialization logic here
+    user_record.compression_info = CompressionInfo::new_decompressed()?;
+    user_record.owner = ctx.accounts.user.key();
+    user_record.name = name;
+    user_record.score = 0;
+
+    Ok(())
+}
+```
+
+### 2. Update Instructions
+
+Implement update instructions for your account types with your custom business logic.
+
+## Customization
+
+### Custom Seeds
+
+Use custom seeds in your PDA derivation and pass them in the `seeds` parameter when decompressing:
+
+```rust
+seeds = [b"custom_prefix", user.key().as_ref(), &session_id.to_le_bytes()]
+```
+
+## Best Practices
+
+1. **Create Config Early**: Create the config immediately after program deployment
+2. **Use Config Values**: Always use config values instead of hardcoded constants
+3. **Validate Rent Recipient**: The macro automatically validates rent recipient matches config
+4. **Handle Compression Timing**: Respect the compression delay from config
+5. **Batch Operations**: Use decompress_multiple_pdas for efficiency
+
+## Migration from Manual Implementation
+
+If migrating from a manual implementation:
+
+1. Update your account structs to use `CompressionInfo` instead of separate fields
+2. Implement the `HasCompressionInfo` trait
+3. Replace your manual instructions with the macro
+4. Update client code to use the new instruction names

+# Compressible Config in anchor-compressible
+
+This program demonstrates how to use the Light SDK's compressible config system to manage compression parameters globally.
+
+## Overview
+
+The compressible config allows programs to:
+
+- Set global compression parameters (delay, rent recipient, address space)
+- Ensure only authorized parties can modify these parameters
+- Validate configuration at runtime
+
+## Instructions
+
+### 1. `initialize_compression_config`
+
+Creates the global config PDA. **Can only be called by the program's upgrade authority**.
+
+**Accounts:**
+
+- `payer`: Transaction fee payer
+- `config`: Config PDA (derived with seed `"compressible_config"`)
+- `program_data`: Program's data account (for upgrade authority validation)
+- `authority`: Program's upgrade authority (must sign)
+- `system_program`: System program
+
+**Parameters:**
+
+- `compression_delay`: Number of slots to wait before compression is allowed
+- `rent_recipient`: Account that receives rent from compressed PDAs
+- `address_space`: Address space for compressed accounts
+
+### 2. `update_compression_config`
+
+Updates the config. **Can only be called by the config's update authority**.
+
+**Accounts:**
+
+- `config`: Config PDA
+- `authority`: Config's update authority (must sign)
+
+**Parameters (all optional):**
+
+- `new_compression_delay`: New compression delay
+- `new_rent_recipient`: New rent recipient
+- `new_address_space`: New address space
+- `new_update_authority`: Transfer update authority to a new account
+
+### 3. `create_record`
+
+Creates a compressed user record using config values.
+
+**Additional Accounts:**
+
+- `config`: Config PDA
+- `rent_recipient`: Must match the config's rent recipient
+
+### 4. `compress_record`
+
+Compresses a PDA using config values.
+
+**Additional Accounts:**
+
+- `config`: Config PDA
+- `rent_recipient`: Must match the config's rent recipient
+
+The compression delay from the config is used to determine if enough time has passed since the last write.
+
+## Security Model
+
+1. **Config Creation**: Only the program's upgrade authority can create the initial config
+2. **Config Updates**: Only the config's update authority can modify settings
+3. **Rent Recipient Validation**: Instructions validate that the provided rent recipient matches the config
+4. **Compression Delay**: Enforced based on config value
+
+## Deployment Process
+
+1. Deploy your program
+2. **Immediately** call `initialize_compression_config` with the upgrade authority
+3. Optionally transfer config update authority to a multisig or DAO
+4. Monitor config changes
+
+## Example Usage
+
+See `examples/config_usage.rs` for complete examples.
+
+## Legacy Instructions
+
+The program still supports legacy instructions that use hardcoded values:
+
+- `create_record`: Uses hardcoded `ADDRESS_SPACE` and `RENT_RECIPIENT`
+- `compress_record`: Uses hardcoded `COMPRESSION_DELAY`
+
+These are maintained for backward compatibility but new integrations should use the config-based versions.
