+- Configuration and rent management for compressible compressed token (CToken) accounts
+- Provides `CompressibleConfig` account structure for Light Registry program integration
+- Implements rent calculation algorithms for determining account compressibility and claimable rent
+- Supports multiple serialization features (Anchor, Pinocchio, Borsh) for program compatibility
+
+# Used in
+- `light-compressed-token` - Uses CompressibleConfig for account creation, rent claiming, and closing
+- `light-ctoken-types` - Imports CompressibleConfig for compressible extension in token accounts
+- `light-registry` - Validates CompressibleConfig for compress & close via registry operations
+- `compressed-token-sdk` - Uses rent functions in compress & close instruction builders
+- `token-client` - Imports rent calculation helpers for test utilities

+```
+
+### Discriminator
+`[180, 4, 231, 26, 220, 144, 55, 168]` - 8-byte discriminator for account validation
+
+### Ownership
+**Owner:** Light Registry Program (`Lighton6oQpVkeewmo2mcPTQQp7kYHr4fWpAgJyEmDX`)
+
+### PDA Derivation
+**Seeds:** `[b"compressible_config", version.to_le_bytes()]`
+
+**Bump:** Stored in account at `bump` field
+
+**Common PDAs:**
+- **V1 Config:** `derive_v1_config_pda(program_id)` - version = 1
+- **Default:** `derive_default_pda(program_id)` - version = 0
+
+```rust
+// Derive any version
+let (pda, bump) = CompressibleConfig::derive_pda(
+    &program_id,
+    version // u16
+);
+
+// Derive V1 config (most common)
+let v1_pda = CompressibleConfig::ctoken_v1_config_pda();
+```
+
+
+**State Validation Methods:**
+- `validate_active()` - Requires state == Active (for new account creation)
+- `validate_not_inactive()` - Requires state != Inactive (for claims/closing)
+
+### Associated Instructions
+
+**Light Registry Program:**
+- `update_compressible_config` - Updates config state and parameters
+- `withdraw_funding_pool` (discriminator: 108) - Withdraws from rent_sponsor pool
+
+**Compressed Token Program (uses config):**
+- `CreateTokenAccount` (discriminator: 18) - Creates ctoken with compressible extension
+- `CreateAssociatedTokenAccount` (discriminator: 103) - Creates ATA with compressible
+- `Claim` (discriminator: 107) - Claims rent using config parameters
+- `CompressAndClose` (via Transfer2) - Uses compression_authority from config
+
+**Registry Program (via wrapper):**
+- `compress_and_close` - Registry-authorized compression using compression_authority
+
+### Serialization
+
+**Zero-copy (for programs):**
+```rust
+use bytemuck::pod_from_bytes;
+
+// Direct deserialization (no discriminator check)
+let config = pod_from_bytes::<CompressibleConfig>(&account_data[8..])?;
+
+// Access fields directly
+let version = config.version;
+let is_active = config.state == 1;
+```
+
+**Borsh (for clients):**
+```rust
+use borsh::BorshDeserialize;
+
+// Skip discriminator and deserialize
+let config = CompressibleConfig::deserialize(&mut &account_data[8..])?;
+
+// Or with discriminator check
+if &account_data[..8] != CompressibleConfig::DISCRIMINATOR {
+    return Err(Error::InvalidDiscriminator);
+}
+let config = CompressibleConfig::deserialize(&mut &account_data[8..])?;
+```
+
+**Anchor (when feature enabled):**
+```rust
+use anchor_lang::AccountDeserialize;
+
+// Includes discriminator validation
+let config = CompressibleConfig::try_deserialize(&mut &account_data[..])?;
+```
+
+### Security Notes
+- Update authority can modify config state but cannot withdraw funds
+- Withdrawal authority can only withdraw from rent_sponsor PDA pool
+- Rent authority (Registry PDA) enables permissionless compression by a forester node when conditions met
+- Config state determines instruction availability:
+  - Active: All operations allowed
+  - Deprecated: No new account creation, existing operations continue
+  - Inactive: Config cannot be used
+
+### Default Values
+```rust
+// CToken V1 defaults
+RentConfig {
+    base_rent: 1220,                    // BASE_RENT constant
+    compression_cost: 11000, // COMPRESSION_COST + COMPRESSION_INCENTIVE
+    lamports_per_byte_per_epoch: 10,                  // RENT_PER_BYTE constant
+}
+
+// Default address space (V1)
+address_space[0] = pubkey!("amt2kaJA14v3urZbZvnc5v2np8jqvc4Z8zDep5wbtzx")
+```
+
+### Methods
+
+**Constants:**
+- `LEN = 256` - Account size in bytes
+
+**State Validation:**
+- `validate_active()` - Ensures config is Active (for account creation)
+- `validate_not_inactive()` - Ensures config is not Inactive (for operations)
+
+**Constructors:**
+- `ctoken_v1(update, withdrawal)` - V1 config with default rent params
+- `new_ctoken(version, active, update, withdrawal, rent)` - Custom ctoken config
+- `new(...)` - Full constructor with all fields
+
+**PDA Derivation:**
+- `derive_pda(program_id, version)` - Derive config account address
+- `ctoken_v1_config_pda()` - Get V1 config for Light Registry
+- `derive_v1_config_pda(program_id)` - Get V1 config for any program
+- `derive_default_pda(program_id)` - Get V0 config for any program
+
+**Seed Helpers:**
+- `get_compression_authority_seeds(version)` - Seeds for rent authority PDA
+- `get_rent_sponsor_seeds(version)` - Seeds for rent recipient PDA

+# Error Types
+
+## CompressibleError
+
+Error codes for the compressible crate, using the 19xxx number range.
+
+**Path:** `program-libs/compressible/src/error.rs`
+
+### FailedBorrowRentSysvar
+
+**Error Code:** 19001
+
+**Description:** Failed to borrow the rent sysvar when calculating rent exemption.
+
+**Common Causes:**
+- Rent sysvar is not available in the current execution context
+- Running in a test environment without proper sysvar setup
+- Corrupted or invalid sysvar account
+
+**Resolution:**
+- Ensure the rent sysvar is properly initialized in test environments
+- For on-chain programs, verify the sysvar is accessible
+- Check that the program has proper permissions to read sysvars
+
+**Usage Example:**
+```rust
+// In get_rent_exemption_lamports function
+let rent = solana_program::rent::Rent::get()
+    .map_err(|_| CompressibleError::FailedBorrowRentSysvar)?;
+```
+
+---
+
+### InvalidState
+
+**Error Code:** 19002
+
+**Description:** The CompressibleConfig account has an invalid state value for the requested operation.
+
+**Common Causes:**
+- Attempting to create new accounts with a config in `Deprecated` or `Inactive` state
+- Using an `Inactive` config for any operation (claim, withdraw, compress & close)
+- Config state field contains an unrecognized value (not 0, 1, or 2)
+
+**Resolution:**
+- For account creation: Ensure config state is `Active` (1)
+- For other operations: Ensure config state is not `Inactive` (0)
+- Contact the config update authority to activate the config if needed
+
+**State Values:**
+- `0` - Inactive: Config cannot be used
+- `1` - Active: All operations allowed
+- `2` - Deprecated: No new accounts, existing operations continue
+
+**Usage Examples:**
+```rust
+// Account creation requires Active state
+config.validate_active()  // Fails with InvalidState if not Active
+
+// Operations require not Inactive
+config.validate_not_inactive()  // Fails with InvalidState if Inactive
+```
+
+## Error Conversions
+
+**HasherError:** The crate includes automatic conversion from `light_hasher::HasherError` (7xxx error codes). See the light-hasher crate documentation for specific hasher error details.
+
+## Feature-Specific Conversions
+
+The error types support conversion to different program error types based on features:
+
+- **Solana (default):** Converts to `solana_program_error::ProgramError`
+- **Anchor:** Converts to `anchor_lang::prelude::ProgramError`
+- **Pinocchio:** Converts to `pinocchio::program_error::ProgramError`
+
+All conversions preserve the numeric error code for consistent error tracking.

+# Rent Calculation APIs
+
+## Description
+Rent calculation functions determine when compressible ctoken accounts can be compressed or paid rent be claimed.
+
+**Key Concepts:**
+- **Rent Epochs:** Rent is calculated per epoch (432,000 slots). Accounts must maintain sufficient balance for all epochs since last claim.
+- **Compression Incentive:** Accounts receive `COMPRESSION_COST + COMPRESSION_INCENTIVE` when created to cover future compression.
+- **Partial Epochs:** When closing, partial epoch rent is returned to the user, completed epochs go to rent recipient.
+- **Compressibility Window:** Accounts become compressible when they lack rent for the current epoch + 1.
+
+## Constants
+
+```rust
+pub const COMPRESSION_COST: u16 = 10_000;       // Base compression operation cost (5000 lamports compression fee + 5000 lamports forester tx fee)
+pub const COMPRESSION_INCENTIVE: u16 = 1000;    // Incentive for compression for the forester node
+pub const BASE_RENT: u16 = 1220;                 // Minimum rent per epoch
+pub const RENT_PER_BYTE: u8 = 10;               // Rent per byte per epoch
+pub const SLOTS_PER_EPOCH: u64 = 432_000;       // Solana slots per epoch
+```
+
+## RentConfig
+
+**Path:** `program-libs/compressible/src/rent.rs`
+
+**Size:** 8 bytes
+
+```rust
+pub struct RentConfig {
+    pub base_rent: u16,                   // Minimum rent per epoch
+    pub compression_cost: u16, // Total compression cost + incentive
+    pub lamports_per_byte_per_epoch: u8,               // Rent per byte per epoch
+    _place_holder_bytes: [u8; 3],       // Padding
+}
+```
+
+### RentConfig Methods
+
+- `rent_curve_per_epoch(num_bytes)` - Calculate rent for given bytes per epoch
+- `get_rent(num_bytes, epochs)` - Calculate total rent for multiple epochs
+- `get_rent_with_compression_cost(num_bytes, epochs)` - Rent plus compression costs
+
+## Core Functions
+
+### Rent Calculation
+
+#### `rent_curve_per_epoch`
+```rust
+pub fn rent_curve_per_epoch(base_rent: u64, lamports_per_byte_per_epoch: u64, num_bytes: u64) -> u64
+```
+Calculates rent required per epoch for an account of given size.
+
+**Formula:** `base_rent + (num_bytes * lamports_per_byte_per_epoch)`
+
+**Use:** Base calculation for all rent operations
+
+---
+
+#### `get_rent`
+```rust
+pub fn get_rent(base_rent: u64, lamports_per_byte_per_epoch: u64, num_bytes: u64, epochs: u64) -> u64
+```
+Calculates total rent for multiple epochs.
+
+**Formula:** `rent_curve_per_epoch * epochs`
+
+**Use:** Calculate rent requirements for future epochs
+
+---
+
+#### `get_rent_exemption_lamports`
+```rust
+pub fn get_rent_exemption_lamports(num_bytes: u64) -> Result<u64, CompressibleError>
+```
+Returns Solana's rent-exempt balance for account size.
+
+**Returns:** Minimum lamports to keep account rent-exempt
+
+**Error:** `FailedBorrowRentSysvar` if rent sysvar unavailable
+
+### Compressibility Check
+
+#### `calculate_rent_and_balance`
+```rust
+pub fn calculate_rent_and_balance(
+    num_bytes: u64,
+    current_slot: u64,
+    current_lamports: u64,
+    last_claimed_slot: impl ZeroCopyNumTrait,
+    rent_exemption_lamports: u64,
+    base_rent: u64,
+    lamports_per_byte_per_epoch: u64,
+    compression_cost: u64,
+) -> (bool, u64)
+```
+Determines if an account is compressible and calculates deficit if needed.
+
+**Returns:** `(is_compressible, lamports_deficit)`
+- `true, deficit` - Account can be compressed, needs `deficit` lamports
+- `false, 0` - Account has sufficient rent, not compressible
+
+**Logic:**
+1. Calculates epochs since last claim
+2. Determines required rent for those epochs
+3. Checks if account balance covers required rent
+4. Returns compressibility status and any deficit
+
+**Use:** Primary check before compression operations
+
+### Rent Claims
+
+#### `claimable_lamports`
+```rust
+pub fn claimable_lamports(

+) -> Option<u64>
+```
+Calculates rent that can be claimed from a funded account.
+
+**Returns:**
+- `Some(amount)` - Claimable rent for completed epochs
+- `None` - Account is compressible (should compress, not claim)
+
+**Logic:**
+1. First checks if account is compressible
+2. If not compressible, calculates rent for completed epochs only
+3. Current ongoing epoch rent cannot be claimed
+
+**Use:** Determine claimable amount in `Claim` instruction
+
+### Close Account Distribution

+    rent_exemption_lamports: u64,
+    base_rent: u64,
+    lamports_per_byte_per_epoch: u64,
+    compression_cost: u64,
+) -> (u64, u64)
+```
+Splits account lamports between rent recipient and user on close.
+
+**Returns:** `(lamports_to_rent_sponsor, lamports_to_user)`
+
+**Logic:**
+1. Calculates unutilized rent (partial epoch remainder)
+2. Rent recipient gets: total - unutilized
+3. User gets: unutilized lamports
+
+**Use:** Distribute funds when closing compressible accounts
+
+### Helper Functions

+#### `calculate_rent_inner`
+```rust
+pub fn calculate_rent_inner<const INCLUDE_CURRENT: bool>(
+    num_bytes: u64,
+    current_slot: u64,
+    current_lamports: u64,
+    last_claimed_slot: impl ZeroCopyNumTrait,

+    base_rent: u64,
+    lamports_per_byte_per_epoch: u64,
+    compression_cost: u64,
+) -> (u64, u64, u64, u64)
+```
+Internal calculation function for rent analysis.
+
+**Returns:** `(required_epochs, rent_per_epoch, epochs_paid, unutilized_lamports)`
+- `required_epochs` - Total epochs needing rent (includes current if INCLUDE_CURRENT=true)
+- `rent_per_epoch` - Rent amount per epoch
+- `epochs_paid` - Number of epochs covered by available balance

+) -> u64
+```
+Determines the last epoch covered by rent payments.
+
+**Returns:** Last epoch number with paid rent
+
+**Use:** Track rent payment status
+
+## Usage Examples
+
+### Check if account is compressible
+```rust
+let (is_compressible, deficit) = calculate_rent_and_balance(
+    261,        // account size
+    1000000,    // current slot
+    5000000,    // current lamports
+    0,          // last claimed slot
+    2000000,    // rent exempt amount
+    1220,       // min rent
+    10,         // rent per byte
+    11000,      // compression incentive

+# Solana Rent vs Light Protocol Rent
+
+## Overview
+
+This document explains the differences between Solana's native rent system and Light Protocol's rent implementation for compressible CToken accounts.
+
+## Solana Native Rent
+
+### Core Concepts
+
+**Rent Exemption:** Solana accounts must maintain a minimum balance to be rent-exempt, calculated as:
+```
+minimum_balance = (ACCOUNT_STORAGE_OVERHEAD + data_len) * lamports_per_byte * exemption_threshold
+```
+
+**Key Constants:**
+- `ACCOUNT_STORAGE_OVERHEAD`: 128 bytes (metadata overhead)
+- `DEFAULT_LAMPORTS_PER_BYTE`: 6960 lamports (SIMD-0194)
+- `DEFAULT_EXEMPTION_THRESHOLD`: 2.0 years
+- `DEFAULT_BURN_PERCENT`: 50% of collected rent is burned
+
+**Rent Collection:** Non-exempt accounts are charged rent based on:
+- Account size (data + 128 bytes overhead)
+- Time elapsed (in years)
+- Rental rate (lamports per byte-year)
+
+## Light Protocol Rent
+
+### Design Philosophy
+
+Light Protocol's rent system is designed for **compressible token accounts** with different goals:
+- Incentivize compression when accounts run out of rent
+- Distribute rent to protocol participants (not burn)
+- Use epoch-based accounting (not continuous time)
+
+### Key Differences
+
+| Aspect | Solana Rent | Light Protocol Rent |
+|--------|-------------|-------------------|
+| **Time Unit** | Years (continuous) | Epochs (discrete, 432,000 slots) |
+| **Rent Rate** | ~6960 lamports/byte for 2 years exemption | 1220 min + 10/byte per epoch |
+| **Exemption** | Permanent with sufficient balance | Temporary, epoch-by-epoch |
+| **Collection** | Automatic by runtime | Manual via Claim instruction |
+| **Distribution** | 50% burned, 50% to validators | 100% to rent recipient (protocol) |
+| **Rent-Specific Data** | None (uses account balance) | 88 bytes (CompressionInfo) |
+| **Compression** | N/A | Incentivized with 11,000 lamport bonus |
+
+### Rent Calculation Comparison
+
+**Solana (rent-exempt for 100 bytes):**
+```rust
+// Using Solana's Rent sysvar
+let rent = Rent::get()?;
+let minimum_balance = rent.minimum_balance(100);
+// Result: (128 + 100) * 6960 = 1,586,880 lamports
+```
+
+**Light Protocol (rent for 100 bytes):**
+```rust
+// Per epoch rent
+let rent_per_epoch = rent_curve_per_epoch(1220, 10, 100);
+// Result: 1220 + (100 * 10) = 2220 lamports per epoch
+
+// To maintain for ~2 years (1051 epochs)
+let two_year_rent = 2220 * 1051 = 2,333,220 lamports
+```
+
+### Compressibility Window
+
+Unlike Solana's binary rent-exempt status, Light Protocol uses a **compressibility window**:
+
+1. **Funded:** Account has rent for current epoch + 1
+2. **Compressible:** Account lacks rent for current epoch + 1
+3. **Claimable:** Account funded but past epochs unclaimed
+
+This creates economic incentives:
+- Users fund accounts minimally (just enough epochs)
+- Protocol can compress inactive accounts
+- Rent flows to protocol treasury, not burned
+
+### Integration with Solana
+
+Light Protocol accounts still interact with Solana's rent system:
+
+1. **Base Rent Exemption:** CToken accounts need Solana rent exemption
+   - Retrieved via `get_rent_exemption_lamports()`
+   - Uses Solana's Rent sysvar internally
+   - Subtracted from available balance for Light rent calculations
+
+2. **Account Creation:** Must satisfy both:
+   - Solana rent exemption (base lamports)
+   - Light Protocol rent (additional lamports)
+   - Compression incentive (11,000 lamports)
+
+3. **Account Closure:** Lamports distributed as:
+   - Solana rent exemption → returned to user
+   - Completed epoch rent → rent recipient
+   - Partial epoch rent → user
+   - Compression incentive → forester node (when compressed)
+
+## Implementation Details
+
+### Rent Sysvar Access
+
+Light Protocol accesses Solana's Rent sysvar to determine base exemption:
+
+```rust
+// program-libs/compressible/src/rent.rs
+pub fn get_rent_exemption_lamports(_num_bytes: u64) -> Result<u64, CompressibleError> {
+    #[cfg(target_os = "solana")]
+    {
+        use solana_program::rent::Rent;
+        use solana_program::sysvar::Sysvar;
+
+        let rent = Rent::get()
+            .map_err(|_| CompressibleError::FailedBorrowRentSysvar)?;
+        Ok(rent.minimum_balance(_num_bytes as usize))
+    }
+    #[cfg(not(target_os = "solana"))]
+    {
+        // Test environment mock
+        Ok(2_282_880)
+    }
+}
+```
+
+### Epoch vs Year Conversion
+
+- **Solana:** Uses floating-point years (deprecated in SIMD-0194)
+- **Light:** Uses integer epochs (432,000 slots = ~2.5 days)
+- **Conversion:** ~1051 epochs ≈ 2 years
+
+## Summary
+
+Light Protocol's rent system is a **layer on top** of Solana's rent that:
+- Requires Solana rent exemption as a base
+- Adds epoch-based rent for protocol sustainability
+- Incentivizes compression of inactive accounts
+- Distributes rent to protocol instead of burning
+
+This dual-rent model ensures accounts remain valid on Solana while enabling Light Protocol's compression economics.

+# Summary
+1. This is a compressed token program implementation similar to spl-token program.
+2. The program supports compressed token accounts and ctoken solana accounts (decompressed compressed tokens but not spl tokens)
+3. The account layout of ctoken solana accounts is the same as for spl tokens, but we implemented a custom extension Compressible.
+4. Compressed mint accounts cmints support one extension TokenMetadata.
+
+# Accounts
+- Compressed tokens can be decompressed to spl tokens. Spl tokens are not explicitly listed here.
+- **description**
+- **discriminator**
+- **state layout**
+- **serialization example**
+- **hashing** (only for compressed accounts)
+- **derivation:** (only for pdas)
+- **associated instructions** (create, close, update)
+
+**Accounts:**
+- you will find all accounts of and related to the CToken program in `programs/compressed-token/program/docs/ACCOUNTS.md`
+1. Solana Accounts
+  1.1. CToken (`CompressedToken`)
+  1.2. Associated CToken (`CompressedToken`)
+  1.3. Extension: Compressible Config (`CompressibleConfig`)
+2. Compressed Accounts
+  2.1. Compressed Token (`TokenData`)
+  2.2. Compressed Mint (`CompressedMint`)
+
+
+
+
+# Instructions
+
+**Instruction Schema:**
+Every instruction description must include the sections:
+- **path** path to instruction code in the program
+- **description** highlevel description what the instruction does including accounts used and their state layout (paths to the code), usage flows what the instruction does
+- **instruction_data** paths to code where instruction data structs are defined
+- **Accounts** accounts in order including checks
+- **instruction logic and checks**
+- **Errors** possible errors and description what causes these errors
+
+## Instruction Index
+
+### Account Management
+1. **Create CToken Account** - [`docs/instructions/CREATE_TOKEN_ACCOUNT.md`](docs/instructions/CREATE_TOKEN_ACCOUNT.md)
+   - Create regular token account (discriminator: 18, enum: `CTokenInstruction::CreateTokenAccount`)
+   - Create associated token account (discriminator: 6, enum: `CTokenInstruction::CreateAssociatedTokenAccount`)
+   - Create associated token account idempotent (discriminator: 101, enum: `CTokenInstruction::CreateAssociatedTokenAccountIdempotent`)
+   - **Config validation:** Requires ACTIVE config only
+
+2. **Close Token Account** - `src/close_token_account.rs` (discriminator: 9, enum: `CTokenInstruction::CloseTokenAccount`)
+   - Close decompressed token accounts
+   - Returns rent exemption to rent recipient if compressible
+   - Returns remaining lamports to destination account
+
+### Rent Management
+3. **Claim** - [`docs/instructions/CLAIM.md`](docs/instructions/CLAIM.md)
+   - Claims rent from expired compressible accounts (discriminator: 107, enum: `CTokenInstruction::Claim`)
+   - **Config validation:** Not inactive (active or deprecated OK)
+
+4. **Withdraw Funding Pool** - [`docs/instructions/WITHDRAW_FUNDING_POOL.md`](docs/instructions/WITHDRAW_FUNDING_POOL.md)
+   - Withdraws funds from rent recipient pool (discriminator: 108, enum: `CTokenInstruction::WithdrawFundingPool`)
+   - **Config validation:** Not inactive (active or deprecated OK)
+
+### Token Operations
+5. **Transfer2** - [`docs/instructions/TRANSFER2.md`](docs/instructions/TRANSFER2.md)
+   - Batch transfer instruction for compressed/decompressed operations (discriminator: 104, enum: `CTokenInstruction::Transfer2`)
+   - Supports Compress, Decompress, CompressAndClose operations
+   - Multi-mint support with sum checks
+
+6. **MintAction** - [`docs/instructions/MINT_ACTION.md`](docs/instructions/MINT_ACTION.md)
+   - Batch instruction for compressed mint management and mint operations (discriminator: 106, enum: `CTokenInstruction::MintAction`)
+   - Supports 9 action types: CreateCompressedMint, MintTo, UpdateMintAuthority, UpdateFreezeAuthority, CreateSplMint, MintToCToken, UpdateMetadataField, UpdateMetadataAuthority, RemoveMetadataKey
+   - Handles both compressed and decompressed token minting
+
+7. **CTokenTransfer** - `src/ctoken_transfer.rs` (discriminator: 3, enum: `CTokenInstruction::CTokenTransfer`)
+   - Transfer between decompressed accounts
+
+## Config State Requirements Summary
+- **Active only:** Create token account, Create associated token account
+- **Not inactive:** Claim, Withdraw, Compress & Close (via registry)
+
+# Source Code Structure (`src/`)
+
+## Core Instructions
+- **`create_token_account.rs`** - Create regular ctoken accounts with optional compressible extension
+- **`create_associated_token_account.rs`** - Create deterministic ATA accounts
+- **`close_token_account/`** - Close ctoken accounts, handle rent distribution
+- **`ctoken_transfer.rs`** - SPL-compatible transfers between decompressed accounts
+
+## Token Operations
+- **`transfer2/`** - Unified transfer instruction supporting multiple modes
+  - `native_compression/` - Compress & close functionality
+  - `delegate/` - Delegated transfer authorization
+- **`mint_action/`** - Mint tokens to compressed/decompressed accounts
+
+## Rent Management
+- **`claim/`** - Claim rent from expired compressible accounts
+- **`withdraw_funding_pool.rs`** - Withdraw funds from rent recipient pool
+
+## Shared Components
+- **`shared/`** - Common utilities used across instructions
+  - `initialize_ctoken_account.rs` - Token account initialization with extensions
+  - `create_pda_account.rs` - PDA creation and validation
+  - `transfer_lamports.rs` - Safe lamport transfer helpers
+- **`extensions/`** - Extension handling (compressible, metadata)
+- **`constants.rs`** - Program seeds and constants
+- **`lib.rs`** - Main entry point and instruction dispatch
+
+## Data Structures
+All state and instruction data structures are defined in **`program-libs/ctoken-types/`** (`light-ctoken-types` crate):
+- **`state/`** - Account state structures (CompressedToken, TokenData, CompressedMint)
+- **`instructions/`** - Instruction data structures for all operations
+- **`state/extensions/`** - Extension data (Compressible, TokenMetadata)
+
+**Why separate crate:** Data structures are isolated from program logic so SDKs can import types without pulling in program dependencies.
+
+## Error Codes
+Custom error codes are defined in **`programs/compressed-token/anchor/src/lib.rs`** (`anchor_compressed_token::ErrorCode` enum):
+- Contains all program-specific error codes used across compressed token operations
+- Errors are returned as `ProgramError::Custom(error_code as u32)` on-chain
+
+## SDKs (`sdk-libs/`)
+- **`compressed-token-sdk/`** - SDK for programs to interact with compressed tokens (CPIs, instruction builders)
+- **`token-client/`** - Client SDK for Rust applications (test helpers, transaction builders)
+
+## Compressible Extension Documentation
+When working with ctoken accounts that have the compressible extension (rent management), you **MUST** read:
+- **`program-libs/compressible/docs/`** - Complete rent system documentation
+  - `RENT.md` - Rent calculations, compressibility checks, lamport distribution
+  - `CONFIG_ACCOUNT.md` - CompressibleConfig account structure
+  - `SOLANA_RENT.md` - Comparison of Solana vs Light Protocol rent systems
+- **Key concepts:**
+  - Rent authority can compress accounts only when `is_compressible()` returns true
+  - Lamport distribution on close: rent → rent_sponsor, unutilized → destination
+  - Compression incentive for foresters when rent authority compresses

+## Solana Accounts
+- The compressed token program uses
+
+### CToken
+- **description**
+  struct `CToken`
+  ctoken solana account with spl token compatible state layout
+  path: `program-libs/ctoken-types/src/state/ctoken/ctoken_struct.rs`
+  crate: `light-ctoken-types`
+- **associated instructions**
+  1. `CreateTokenAccount` `18`
+  2. `CloseTokenAccount` `9`
+  3. `CTokenTransfer` `3`
+  4. `Transfer2` `104` - `Decompress`, `DecompressAndClose`
+  5. `MintAction` `106` - `MintToCToken`
+  6. `Claim` `107`
+- **serialization example**
+  borsh and zero copy deserialization deserialize the compressible extension, spl serialization only deserialize the base token data.
+  zero copy: (always use in programs)
+  ```rust
+  use light_ctoken_types::state::ctoken::CToken;
+  use light_zero_copy::traits::{ZeroCopyAt, ZeroCopyAtMut};
+
+  let (token, _) = CToken::zero_copy_at(&account_data)?;
+  let (mut token, _) = CToken::zero_copy_at_mut(&mut account_data)?;
+  ```
+
+  borsh: (always use in client non solana program code)
+  ```rust
+  use borsh::BorshDeserialize;
+  use light_ctoken_types::state::ctoken::CToken;
+
+  let token = CToken::deserialize(&mut &account_data[..])?;
+  ```
+
+  spl serialization: (preferably use other serialization)
+  ```rust
+  use spl_pod::bytemuck::pod_from_bytes;
+  use spl_token_2022::pod::PodAccount;
+
+  let pod_account = pod_from_bytes::<PodAccount>(&account_data[..165])?;
+  ```
+
+
+### Associated CToken
+- **description**
+  struct `CToken`
+  ctoken solana account with spl token compatible state layout
+- **derivation:**
+  seeds: [owner, ctoken_program_id, mint]
+- the same as `CToken`
+
+
+### Compressible Config
+- owned by the LightRegistry program
+- defined in path `program-libs/compressible/src/config.rs`
+- crate: `light-compressible`
+
+
+## Compressed Accounts
+
+### Compressed Token
+- compressed token account.
+- version describes the hashing and the discriminator. (program-libs/ctoken-types/src/state/token_data_version.rs)
+    pub enum TokenDataVersion {
+        V1 = 1u8, // discriminator [2, 0, 0, 0, 0, 0, 0, 0], // 2 le (Poseidon hashed)
+        V2 = 2u8, // discriminator [0, 0, 0, 0, 0, 0, 0, 3], // 3 be (Poseidon hashed)
+        ShaFlat = 3u8, // discriminator [0, 0, 0, 0, 0, 0, 0, 4], // 4 be (Sha256 hash of borsh serialized data truncated to 31 bytes so that hash is less than be bn254 field size)
+    }
+
+### Compressed Mint
+
+## Extensions
+The compressed token program supports 2 extensions.
+
+### TokenMetadata
+- Mint extension, compatible with TokenMetada extension of Token2022.
+- Only available in compressed mints.
+
+### Compressible
+- Token account extension, Token2022 does not have an equivalent extension.
+- Only available in ctoken solana accounts (decompressed ctokens), not in compressed token accounts.

+## Claim
+
+**discriminator:** 107
+**enum:** `InstructionType::Claim`
+**path:** programs/compressed-token/program/src/claim/
+
+**description:**
+1. Claims rent from compressible ctoken solana accounts that have passed their rent expiration epochs
+2. Account layout `CToken` is defined in path: program-libs/ctoken-types/src/state/ctoken/ctoken_struct.rs
+3. Extension layout `CompressionInfo` is defined in path: program-libs/ctoken-types/src/state/extensions/compressible.rs
+4. Processes multiple token accounts in a single instruction for efficiency
+5. For each eligible compressible account:
+   - Updates the account's RentConfig from the CompressibleConfig
+   - Updates the config_account_version to match current config version
+   - Calculates claimable rent based on completed epochs since last claim
+   - Updates the `last_claimed_slot` in the compressible extension
+   - Transfers claimable lamports from token account to rent sponsor PDA
+6. RentConfig is updated for ALL accounts with compressible extension (even those without claimable rent)
+7. Only accounts with compressible extension can be claimed from
+8. Only the compression authority (from CompressibleConfig) can execute claims
+9. **Config validation:** Config must not be inactive (active or deprecated allowed)
+10. Accounts that don't meet claim criteria are skipped without error
+11. Multiple accounts can be claimed in a single transaction for efficiency
+12. Only completed epochs are claimed, partial epochs remain with the account
+13. The instruction is designed to be called periodically by foresters
+
+**Instruction data:**
+- Single byte: pool PDA bump
+- Used to validate the rent_sponsor PDA derivation
+
+**Accounts:**
+1. rent_sponsor
+   - (mutable)
+   - The pool PDA that receives claimed rent
+   - Must match the rent_sponsor in CompressibleConfig
+   - Derivation validated using provided bump
+
+2. compression_authority
+   - (signer)
+   - The authority authorized to claim rent
+   - Must match compression_authority in CompressibleConfig
+   - Typically a forester or system authority
+
+3. compressible_config
+   - (non-mutable)
+   - CompressibleConfig account containing rent parameters
+   - Owner must be Registry program (Lighton6oQpVkeewmo2mcPTQQp7kYHr4fWpAgJyEmDX)
+   - Must not be in inactive state
+
+4. token_accounts (remaining accounts)
+   - (mutable, variable number)
+   - CToken accounts to claim rent from
+   - Each account is processed independently
+   - Accounts without compressible extension are skipped
+   - Invalid accounts (wrong authority/recipient) are skipped without error
+
+**Instruction Logic and Checks:**
+
+1. **Parse instruction data:**
+   - Extract pool PDA bump from first byte
+   - Error if instruction data is empty
+
+2. **Validate fixed accounts:**
+   - Verify compression_authority is a signer
+   - Verify compressible_config is owned by Registry program
+   - Deserialize and validate CompressibleConfig:
+     - Check config is not inactive (validate_not_inactive)
+     - Verify compression_authority matches config
+     - Verify rent_sponsor matches config
+
+3. **Get current slot:**
+   - Fetch from Clock sysvar for epoch calculation
+
+4. **Process each token account:**
+   For each account in remaining accounts:
+
+   a. **Parse account data:**
+      - Borrow mutable data
+      - Deserialize as CToken with zero-copy
+
+   b. **Find and validate compressible extension:**
+      - Search extensions for Compressible variant
+      - Skip if no compressible extension found
+      - Validate compression_authority matches
+      - Validate rent_sponsor matches
+
+   c. **Validate version:**
+      - Verify `compressible_ext.config_account_version` matches CompressibleConfig version
+      - Error if versions don't match (prevents cross-version claims)
+
+   d. **Calculate and claim rent:**
+      - Get account size and current lamports
+      - Calculate rent exemption for account size
+      - Call `compressible_ext.claim()` which:
+        - Determines completed epochs since last claim using CURRENT RentConfig
+        - Calculates claimable lamports
+        - Updates last_claimed_slot if there's claimable rent
+      - Returns None if no rent to claim (account not yet compressible)
+      - After claim calculation, always update `compressible_ext.rent_config` from CompressibleConfig for future operations
+
+   e. **Transfer lamports:**
+      - If claim amount > 0, transfer from token account to rent_sponsor
+      - Update both account balances
+
+5. **Complete successfully:**
+   - All valid accounts processed
+   - Invalid accounts silently skipped
+
+**Errors:**
+
+- `ProgramError::InvalidInstructionData` (error code: 3) - Missing pool PDA bump in instruction data or instruction data is empty
+- `ProgramError::InvalidSeeds` (error code: 14) - compression_authority or rent_sponsor doesn't match CompressibleConfig
+- `ProgramError::InvalidAccountData` (error code: 4) - CompressibleConfig/CToken deserialization fails, config version mismatch, or claim calculation fails
+- `AccountError::NotEnoughAccountKeys` (error code: 12020) - Missing required accounts
+- `AccountError::InvalidSigner` (error code: 12015) - compression_authority is not a signer
+- `AccountError::AccountNotMutable` (error code: 12008) - rent_sponsor is not mutable
+- `CompressibleError::InvalidState` (error code: 19002) - CompressibleConfig is in inactive state

+## Close Token Account
+
+**discriminator:** 9
+**enum:** `CTokenInstruction::CloseTokenAccount`
+**path:** programs/compressed-token/program/src/close_token_account/
+
+**description:**
+1. Closes decompressed ctoken solana accounts and distributes remaining lamports to destination account.
+2. Account layout `CToken` is defined in path: program-libs/ctoken-types/src/state/ctoken/ctoken_struct.rs
+3. Supports both regular (non-compressible) and compressible token accounts (with compressible extension)
+4. For compressible accounts (with compressible extension):
+   - Rent exemption is returned to the rent recipient (destination account)
+   - Write top-up lamports are returned to the authority (original fee payer)
+   - Authority can be either the owner OR the rent authority (if account is compressible)
+5. For non-compressible accounts:
+   - All lamports are transferred to the destination account
+   - Only the owner can close the account
+6. After lamport distribution, the account is zeroed and resized to 0 bytes to prevent revival attacks
+
+**Instruction data:**
+- No instruction data required (empty)
+- The instruction only reads the discriminator byte
+
+**Accounts:**
+1. token_account
+   - (mutable)
+   - The ctoken account being closed
+   - Must be initialized (not frozen or uninitialized)
+   - Must have zero token balance
+   - Data will be zeroed and account resized to 0
+
+2. destination
+   - (mutable)
+   - Receives remaining user funds (non-rent lamports) for all account types
+   - Cannot be the same as token_account
+
+3. authority
+   - (signer)
+   - Either the account owner OR rent authority (for compressible accounts)
+   - For compressible accounts closed by rent authority:
+     - Account must be compressible (past rent expiry)
+     - Authority must match compression_authority in extension
+
+4. rent_sponsor (required for compressible accounts)
+   - (mutable)
+   - Receives rent exemption for compressible accounts
+   - Must match the rent_sponsor in the compressible extension
+   - Not required for non-compressible accounts
+
+**Instruction Logic and Checks:**
+
+1. **Parse and validate accounts** (`validate_and_parse` in `accounts.rs`):
+   - Extract token_account (index 0), destination (index 1), authority (index 2)
+   - Extract rent_sponsor (index 3) if accounts.len() >= 4 (required for compressible accounts)
+   - Verify token_account is mutable via `check_mut`
+   - Verify destination is mutable via `check_mut`
+   - Verify authority is a signer via `check_signer`
+
+2. **Deserialize and validate token account** (`process_close_token_account` in `processor.rs`):
+   - Borrow token account data mutably
+   - Parse as `CToken` using `zero_copy_at_mut` (zero-copy deserialization)
+   - Call `validate_token_account<false>` (CHECK_RENT_AUTH=false for regular close)
+
+3. **Validate closure requirements** (`validate_token_account<CHECK_RENT_AUTH: bool>`):
+   3.1. **Basic validation**:
+      - Verify token_account.key() != destination.key() (prevents self-transfer)
+      - Check account state field equals AccountState::Initialized (value 1):
+        - If state == AccountState::Frozen (value 2): return `ErrorCode::AccountFrozen`
+        - If state is any other value: return `ProgramError::UninitializedAccount`
+
+   3.2. **Balance check** (only when CHECK_RENT_AUTH=false):
+      - Convert compressed_token.amount from U64 to u64
+      - Verify amount == 0 (non-zero returns `ErrorCode::NonNativeHasBalance`)
+
+   3.3. **Authority validation**:
+      - Check if compressed_token.owner == authority.key() (store as `owner_matches`)
+      - If account has extensions vector:
+        3.3.1. Iterate through extensions looking for `ZExtensionStructMut::Compressible`
+        3.3.2. If compressible extension found:
+          - Get rent_sponsor from accounts (returns error if missing)
+          - Verify compressible_ext.rent_sponsor == rent_sponsor.key()
+          - If not owner_matches and CHECK_RENT_AUTH=true:
+            - Verify compressible_ext.compression_authority == authority.key()
+            - Get current slot from Clock sysvar
+            - Call `compressible_ext.is_compressible(data_len, current_slot, lamports)`
+            - If not compressible: return error
+            - Return Ok((true, compress_to_pubkey_flag))
+      - If owner doesn't match and no valid rent authority: return `ErrorCode::OwnerMismatch`
+
+4. **Distribute lamports** (`close_token_account_inner`):
+   4.1. **Setup**:
+      - Get token_account.lamports() amount
+      - Re-verify authority is signer via `check_signer`
+
+   4.2. **Check for compressible extension**:
+      - Borrow token account data (read-only this time)
+      - Parse as CToken using `zero_copy_at`
+      - Look for `ZExtensionStruct::Compressible` in extensions
+
+   4.3. **For compressible accounts** (if extension found):
+      - Get current_slot from Clock::get() sysvar
+      - Calculate base_lamports using `get_rent_exemption_lamports(account.data_len)`
+      - Extract from compressible_ext.rent_config:
+        - base_rent (u16 -> u64)
+        - lamports_per_byte_per_epoch (u8 -> u64)
+        - compression_cost (u16 -> u64)
+      - Call `calculate_close_lamports` with:
+        - data_len, current_slot, total_lamports
+        - last_claimed_slot, base_lamports
+        - base_rent, lamports_per_byte_per_epoch, compression_cost
+      - Returns (lamports_to_rent_sponsor, lamports_to_destination)
+      - Get rent_sponsor account from accounts (error if missing)
+      - Special case: if authority.key() == compression_authority:
+        - Extract compression incentive from lamports_to_rent_sponsor
+        - Add lamports_to_destination to lamports_to_rent_sponsor
+        - Set lamports_to_destination = compression_cost (goes to forester)
+      - Transfer lamports_to_rent_sponsor to rent_sponsor via `transfer_lamports` (if > 0)
+      - Transfer lamports_to_destination to destination via `transfer_lamports` (if > 0)
+      - Return early (skip non-compressible path)
+
+   4.4. **For non-compressible accounts**:
+      - Transfer all token_account.lamports to destination via `transfer_lamports`
+
+5. **Finalize account closure** (`finalize_account_closure`):
+   5.1. Zero the owner field:
+      - Use unsafe block to call `token_account.assign(&[0u8; 32])`
+      - Sets owner to system program (0x00000000...)
+
+   5.2. Resize account to prevent revival:
+      - Call `token_account.resize(0)`
+      - Deallocates all account data
+      - Maps resize error to ProgramError::Custom if fails
+
+**Errors:**
+- `ProgramError::InvalidAccountData` (error code: 4) - token_account == destination, rent_sponsor doesn't match extension, compression_authority mismatch, or account not compressible
+- `ProgramError::NotEnoughAccountKeys` (error code: 11) - Missing rent_sponsor account for compressible accounts
+- `AccountError::InvalidSigner` (error code: 12015) - Authority is not a signer
+- `AccountError::AccountNotMutable` (error code: 12008) - token_account, destination, or rent_sponsor is not mutable
+- `AccountError::NotEnoughAccountKeys` (error code: 12020) - Not enough accounts provided
+- `ErrorCode::AccountFrozen` (error code: 6076) - Account state is Frozen
+- `ProgramError::UninitializedAccount` (error code: 10) - Account state is Uninitialized or invalid
+- `ErrorCode::NonNativeHasBalance` (error code: 6074) - Account has non-zero token balance
+- `ErrorCode::OwnerMismatch` (error code: 6075) - Authority doesn't match owner and isn't valid rent authority
+- `ProgramError::InsufficientFunds` (error code: 6) - Insufficient funds for lamport transfer during rent calculation
+
+**Edge Cases and Considerations:**
+- When rent authority closes an account, all funds (including user funds) go to rent_sponsor
+- Compressible accounts require 4 accounts, non-compressible require only 3
+- The timing check for compressibility uses current slot vs last_claimed_slot
+- The instruction handles accounts with no extensions gracefully (non-compressible path)
+- Zero-lamport accounts are handled without attempting transfers
+- Separation of rent_sponsor from destination allows users to specify where their funds go while ensuring rent goes to the protocol

+## 1. create ctoken account
+
+  **discriminator:** 18
+  **enum:** `CTokenInstruction::CreateTokenAccount`
+  **path:** programs/compressed-token/src/create_token_account.rs
+
+  **description:**
+  1. creates ctoken solana accounts with and without Compressible extension
+  2. account layout `CToken` is defined in path: program-libs/ctoken-types/src/state/ctoken/ctoken_struct.rs
+  3. extension layout `CompressionInfo` is defined in path:
+  program-libs/ctoken-types/src/state/extensions/compressible.rs
+  4. A compressible token means that the ctoken solana account can be compressed by the rent authority as soon as the account balance is insufficient.
+  5. Account creation without the compressible extension:
+    - Initializes an existing 165-byte solana account as a ctoken account (SPL-compatible size)
+    - Only sets mint, owner, and state fields - no extension data
+    - Account must already exist and be owned by the program
+  6. Account creation with compressible extension:
+    - creates the ctoken account via cpi within the instruction, then initializes it.
+    - expects a CompressibleConfig account to read the rent authority, rent recipient and RentConfig from.
+    - if the payer is not the rent recipient the fee payer pays the rent and becomes the rent recipient (the rent recipient is a ctoken program pda that funds rent exemption for compressible ctoken solana accounts)
+
+  **Instruction data:**
+  1. instruction data is defined in path: program-libs/ctoken-types/src/instructions/create_ctoken_account.rs
+  2. Instruction data with compressible extension
+  program-libs/ctoken-types/src/instructions/extensions/compressible.rs
+    - `write_top_up`: Additional lamports allocated for future write operations on the compressed account
+
+  **Accounts:**
+  1. token_account
+    - (signer, mutable)
+    - The ctoken account being created (signer, mutable)
+  2. mint
+    - non mutable
+    - Mint pubkey is used for token account initialization
+    - Account is unchecked and doesn't need to be initialized, allowing compressed mints to be used without providing the compressed account
+
+  Optional accounts required to initialize ctoken account with compressible extension
+  3. payer
+    - (signer, mutable)
+    - User account, pays for the ctoken account rent and compression incentive
+  4. config
+    - non-mutable, owned by LightRegistry program, CompressibleConfig::discriminator matches
+    - used to read RentConfig, rent recipient, and rent authority
+  5. system_program
+    - non mut
+    - required for account creation and rent transfer
+  6. rent_payer_pda
+    - mutable
+    - Pays rent exemption for the compressible token account creation
+    - Used as PDA signer to create the ctoken account
+
+  **Instruction Logic and Checks:**
+  1. Deserialize instruction data
+    - if instruction data len == 32 bytes add 1 byte padding for spl token compatibility
+  2. Parse and check accounts
+    - Validate CompressibleConfig is active (not inactive or deprecated)
+  3. if with compressible account
+    3.1. if with compress to pubkey
+        Compress to pubkey specifies compression to account pubkey instead of the owner.
+        This is useful for pda token accounts that rely on pubkey derivation but have a program wide
+        authority pda as owner.
+        Validates: derives address from provided seeds/bump and verifies it matches token_account pubkey
+        Security: ensures account is a derivable PDA, preventing compression to non-signable addresses
+    3.2. calculate rent (rent exemption + compression incentive)
+    3.3. check whether fee payer is custom fee payer (rent_payer_pda != config.rent_sponsor)
+    3.4. if custom fee payer
+        create account with custom fee payer via cpi (pays both rent exemption + compression incentive)
+    3.5. else
+        3.5.1. create account with `rent_payer_pda` as fee payer via cpi (pays only rent exemption)
+        3.5.2. transfer compression incentive to created ctoken account from payer via cpi
+    3.6. `initialize_ctoken_account`
+        programs/compressed-token/program/src/shared/initialize_ctoken_account.rs
+        3.6.1. compressible extension intialization
+          copy version from config (used to match config PDA version in subsequent instructions)
+          if custom fee payer, set custom fee payer as ctoken account rent recipient
+          else set config account rent recipient as ctoken account rent recipient
+          set `last_claimed_slot` to current slot (tracks when rent was last claimed/initialized for rent calculation)
+
+  **Errors:**
+  - `ProgramError::BorshIoError` (error code: 15) - Failed to deserialize CreateTokenAccountInstructionData from instruction_data bytes
+  - `AccountError::NotEnoughAccountKeys` (error code: 12020) - Missing required accounts
+  - `AccountError::InvalidSigner` (error code: 12015) - token_account or payer is not a signer when required
+  - `AccountError::AccountNotMutable` (error code: 12008) - token_account or payer is not mutable when required
+  - `AccountError::AccountOwnedByWrongProgram` (error code: 12007) - Config account not owned by LightRegistry program
+  - `ProgramError::InvalidAccountData` (error code: 4) - CompressibleConfig pod deserialization fails or compress_to_pubkey.check_seeds() fails
+  - `ProgramError::InvalidInstructionData` (error code: 3) - compressible_config is None in instruction data when compressible accounts provided, or extension data invalid
+  - `ProgramError::UnsupportedSysvar` (error code: 17) - Failed to get Clock sysvar
+  - `CompressibleError::InvalidState` (error code: 19002) - CompressibleConfig is not in active state
+  - `ErrorCode::InsufficientAccountSize` (error code: 6077) - token_account data length < 165 bytes (non-compressible) or < COMPRESSIBLE_TOKEN_ACCOUNT_SIZE (compressible)
+  - `ErrorCode::InvalidCompressAuthority` (error code: 6052) - compressible_config is Some but compressible_config_account is None during extension initialization
+
+
+## 2. create associated ctoken account
+
+  **discriminator:** 103 (non-idempotent), 101 (idempotent)
+  **enum:** `CTokenInstruction::CreateAssociatedTokenAccount` (non-idempotent), `CTokenInstruction::CreateAssociatedTokenAccountIdempotent` (idempotent)
+  **path:** programs/compressed-token/program/src/create_associated_token_account.rs
+
+  **description:**
+  1. Creates deterministic ctoken PDA accounts derived from [owner, ctoken_program_id, mint]
+  2. Supports both non-idempotent (fails if exists) and idempotent (succeeds if exists) modes
+  3. Account layout same as create ctoken account: `CToken` with optional `CompressionInfo`
+  4. Associated token accounts cannot use compress_to_pubkey (always compress to owner)
+  5. Mint is provided via instruction data only - no account validation for compressed mint compatibility
+  6. Token account must be uninitialized (owned by system program) unless idempotent mode
+
+  **Instruction data:**
+  1. instruction data is defined in path: program-libs/ctoken-types/src/instructions/create_associated_token_account.rs
+    - `owner`: Owner pubkey for the associated token account
+    - `mint`: Mint pubkey for the token account
+    - `bump`: PDA bump seed for derivation
+    - `compressible_config`: Optional, same as create ctoken account but compress_to_account_pubkey must be None
+
+  **Accounts:**
+  1. fee_payer
+    - (signer, mutable)
+    - Pays for account creation and compression incentive
+  2. associated_token_account
+    - mutable, NOT signer (it's a PDA being created)
+    - Must be system-owned (uninitialized) unless idempotent
+  3. system_program
+    - non-mutable
+    - Required for account creation
+
+  Optional accounts for compressible extension (same as create ctoken account):
+  4. config
+    - non-mutable, owned by LightRegistry program
+  5. fee_payer_pda
+    - mutable
+    - Either rent_sponsor PDA or custom fee payer
+
+  **Instruction Logic and Checks:**
+  1. Deserialize instruction data
+  2. If idempotent mode:
+    - Validate PDA derivation matches [owner, program_id, mint] with provided bump
+    - Return success if account already owned by program
+  3. Verify account is system-owned (uninitialized)
+    - Validate CompressibleConfig is active (not inactive or deprecated) if compressible
+  4. If compressible:
+    - Reject if compress_to_account_pubkey is Some (not allowed for ATAs)
+    - Calculate rent (prepaid epochs rent + compression incentive, no rent exemption)
+    - Check if custom fee payer (fee_payer_pda != config.rent_sponsor)
+    - Create PDA with fee_payer_pda (either rent_sponsor PDA or custom fee payer) paying rent exemption
+    - Always transfer calculated rent from fee_payer to account via CPI
+  5. If not compressible:
+    - Create PDA with rent-exempt balance only
+  6. Initialize token account (same as ## 1. create ctoken account step 3.6)
+
+  **Errors:**
+  Same as create ctoken account with additions:
+  - `ProgramError::IllegalOwner` (error code: 18) - Associated token account not owned by system program when creating
+  - `ProgramError::InvalidInstructionData` (error code: 3) - compress_to_account_pubkey is Some (forbidden for ATAs)
+  - `AccountError::InvalidSigner` (error code: 12015) - fee_payer is not a signer
+  - `AccountError::AccountNotMutable` (error code: 12008) - fee_payer or associated_token_account is not mutable

+## CToken Transfer
+
+**discriminator:** 3
+**enum:** `InstructionType::CTokenTransfer`
+**path:** programs/compressed-token/program/src/ctoken_transfer.rs
+
+**description:**
+1. Transfers tokens between decompressed ctoken solana accounts, fully compatible with SPL Token semantics
+2. Account layout `CToken` is defined in path: program-libs/ctoken-types/src/state/ctoken/ctoken_struct.rs
+3. Extension layout `CompressionInfo` is defined in path: program-libs/ctoken-types/src/state/extensions/compressible.rs
+4. Uses light_token_22 fork to process the transfer (required because token_22 has hardcoded program ID checks)
+5. After the transfer, automatically tops up compressible accounts with additional lamports if needed:
+   - Calculates top-up requirements based on current slot and account balance
+   - Only applies to accounts with compressible extension
+   - Top-up prevents accounts from becoming compressible during normal operations
+6. Supports standard SPL Token transfer features including delegate authority (multisig not supported)
+7. The transfer amount and authority validation follow SPL Token rules exactly
+
+**Instruction data:**
+- First byte: instruction discriminator (3)
+- Remaining bytes: SPL TokenInstruction::Transfer serialized
+  - `amount`: u64 - Number of tokens to transfer
+
+**Accounts:**
+1. source
+   - (mutable)
+   - The source ctoken account
+   - Must have sufficient balance for the transfer
+   - May receive rent top-up if compressible
+
+2. destination
+   - (mutable)
+   - The destination ctoken account
+   - Must have same mint as source
+   - May receive rent top-up if compressible
+
+3. authority
+   - (signer)
+   - Owner of the source account or delegate with sufficient allowance
+   - Must sign the transaction
+
+4. payer (when accounts have compressible extension)
+   - (signer, mutable)
+   - Pays for rent top-ups if needed
+   - Must be the third account if any account needs top-up
+
+**Instruction Logic and Checks:**
+
+1. **Parse instruction data:**
+
+2. **Validate minimum accounts:**
+   - Require at least 3 accounts (source, destination, authority/payer)
+   - Return NotEnoughAccountKeys if insufficient
+
+3. **Convert account formats:**
+   - Convert Pinocchio AccountInfos to Anchor AccountInfos
+
+4. **Process SPL transfer:**
+   - Call light_token_22::Processor::process_transfer
+
+5. **Calculate top-up requirements:**
+   For each of source and destination accounts:
+
+   a. **Check for compressible extension:**
+      - Skip if account size is base size (no extensions)
+      - Parse extensions if present
+      - Error if extensions exist but no Compressible found
+
+   b. **Calculate top-up amount:**
+      - Get current slot from Clock sysvar (lazy loaded)
+      - Call `calculate_top_up_lamports` which:
+        - Checks if account is compressible
+        - Calculates rent deficit if any
+        - Adds configured lamports_per_write amount
+        - Returns 0 if account is well-funded
+
+6. **Execute top-up transfers:**
+   - Skip if no accounts need top-up (current_slot == 0 indicates no compressible accounts)
+   - Use payer account (third account) as funding source
+   - Execute multi_transfer_lamports to top up both accounts atomically
+   - Update account lamports balances
+
+**Errors:**
+
+- `ProgramError::NotEnoughAccountKeys` (error code: 11) - Less than 3 accounts provided
+- `ProgramError::InvalidInstructionData` (error code: 3) - Instruction is not TokenInstruction::Transfer or failed to unpack instruction data
+- `ProgramError::InsufficientFunds` (error code: 6) - Source balance less than amount (SPL Token error)
+- `ProgramError::Custom` (SPL Token errors) - OwnerMismatch, MintMismatch, AccountFrozen, or InvalidDelegate from SPL token validation
+- `CTokenError::InvalidAccountData` (error code: 18002) - Account has extensions but no Compressible extension or failed to parse extensions
+- `CTokenError::SysvarAccessError` (error code: 18020) - Failed to get Clock sysvar for current slot

+## MintAction
+
+**discriminator:** 106
+**enum:** `CTokenInstruction::MintAction`
+**path:** programs/compressed-token/program/src/mint_action/
+
+**description:**
+Batch instruction for managing compressed mint accounts (cmints) and performing mint operations. A compressed mint account stores the mint's supply, decimals, authorities (mint/freeze), and optional TokenMetadata extension in compressed state. TokenMetadata is the only extension supported for compressed mints and provides fields for name, symbol, uri, update_authority, and additional key-value metadata.
+
+This instruction supports 9 total actions - one creation action (controlled by `create_mint` flag) and 8 enum-based actions:
+
+**Compressed mint creation (executed first when `create_mint=true`):**
+1. **Create Compressed Mint** - Create a new compressed mint account with initial authorities and optional TokenMetadata extension
+
+**Core mint operations (Action enum variants):**
+2. `MintToCompressed` - Mint new compressed tokens to one or more compressed token accounts
+3. `MintToCToken` - Mint new tokens to decompressed ctoken accounts (not SPL tokens)
+4. `CreateSplMint` - Create an SPL Token 2022 mint for an existing compressed mint, enabling SPL interoperability
+
+**Authority updates (Action enum variants):**
+5. `UpdateMintAuthority` - Update or remove the mint authority
+6. `UpdateFreezeAuthority` - Update or remove the freeze authority
+
+**TokenMetadata extension operations (Action enum variants):**
+7. `UpdateMetadataField` - Update name, symbol, uri, or additional_metadata fields in the TokenMetadata extension
+8. `UpdateMetadataAuthority` - Update the metadata update authority in the TokenMetadata extension
+9. `RemoveMetadataKey` - Remove a key-value pair from additional_metadata in the TokenMetadata extension
+
+Key concepts integrated:
+- **Compressed mint (cmint)**: Mint state stored in compressed account with deterministic address derived from associated SPL mint pubkey
+- **SPL mint synchronization**: When SPL mint exists, supply is tracked in both compressed mint and SPL mint through token pool PDAs
+- **Authority validation**: All actions require appropriate authority (mint/freeze/metadata) to be transaction signer
+- **Batch processing**: Multiple actions execute sequentially with state updates persisted between actions
+
+**Instruction data:**

+
+   **MintToCToken:**
+   - Validate: mint authority matches signer
+   - Calculate: sum recipient amounts
+   - Update: mint supply += sum_amounts
+   - If SPL mint exists: mint to pool, then transfer to recipients

+**enum:** `CTokenInstruction::Transfer2`
+**path:** programs/compressed-token/program/src/transfer2/
+
+**description:**
+1. Batch transfer instruction supporting multiple token operations in a single transaction with up to 5 different mints (cmints or spl)
+
+2. Account types and data layouts:
+   - Compressed accounts: `TokenData` (program-libs/ctoken-types/src/state/token_data.rs)
+   - Decompressed Solana accounts: `CToken` for ctokens (program-libs/ctoken-types/src/state/ctoken/ctoken_struct.rs) or standard SPL token accounts

+
+4. Global sum check enforces transaction balance:
+   - Input sum = compressed inputs + compress operations (tokens entering compressed state)
+   - Output sum = compressed outputs + decompress operations (tokens leaving compressed state)
+   - Each mint must balance to zero (input sum = output sum)
+   - Enables implicit cross-type transfers (SPL↔ctoken) without creating compressed accounts

+
+2. Compression struct fields (path: program-libs/ctoken-types/src/instructions/transfer2.rs):
+   - `mode`: CompressionMode enum (Compress, Decompress, CompressAndClose)

+
+3. authority
+   - (signer)
+   - Transaction authority for system operations

+- mint accounts - Referenced by index in instruction data (account doesn't need to exist, only pubkey is used)
+- owner accounts - Token account owners referenced by index
+- delegate accounts - Optional delegates referenced by index
+- token accounts - Decompressed ctoken or SPL token accounts for compress/decompress operations
+
+**Instruction Logic and Checks:**
+
+1. **Common initialization (all paths):**
+   - Deserialize `CompressedTokenInstructionDataTransfer2` using zero-copy
+   - Validate CPI context via `check_cpi_context`: Ensures `set_context || first_set_context` is false when `cpi_context` is Some
+   - Validate instruction data via `validate_instruction_data`:
+     - Check unimplemented features (`in_lamports`, `out_lamports`, `in_tlv`, `out_tlv`) are None
+     - Ensure CPI context write mode (`set_context || first_set_context`) has no compressions
+   - Determine required optional accounts via `Transfer2Config::from_instruction_data`:
+     - Analyzes instruction data to identify which optional accounts must be present
+     - Sets `sol_pool_required` when lamport imbalance exists (input ≠ output lamports)
+     - Sets `sol_decompression_required` when decompressing SOL (input < output lamports)
+     - Sets `cpi_context_required` when CPI context operations needed
+     - Sets `no_compressed_accounts` when no compressed accounts involved (in_token_data and out_token_data both empty)
+     - Uses checked arithmetic to prevent lamport calculation overflow
+   - Validate and parse accounts via `Transfer2Accounts::validate_and_parse`
+
+2. **Branch based on compressed account involvement:**
+
+**Path A: No Compressed Accounts (compressions-only operations)**
+   If `no_compressed_accounts` is true, execute `process_no_system_program_cpi`:
+
+   a. **Validate compressions-only accounts:**
+      - Extract `compressions_only_fee_payer` (error: CompressionsOnlyMissingFeePayer if missing)
+      - Extract `compressions_only_cpi_authority_pda` (error: CompressionsOnlyMissingCpiAuthority if missing)
+      - Validate compressions exist (error: NoInputsProvided if missing)
+
+   b. **Process compression operations:**
+      - Create mint sums tracker (ArrayVec with 5-mint limit)
+      - Run `sum_compressions` to validate compression balance per mint:
+        - For Decompress: verify existing balance (error: SumCheckFailed if no balance to decompress)
+        - Check mint tracker capacity (error: TooManyMints if exceeds 5)
+      - Execute `process_token_compression` for compress/decompress operations
+
+   c. **Close accounts for CompressAndClose operations:**
+      - After compression validation succeeds, close the token accounts:
+        - Lamport distribution via `compressible::calculate_close_lamports`:
+          - Rent exemption + completed epoch rent → rent_sponsor account
+          - Unutilized rent (partial epoch) → destination account
+          - Compression incentive → forester (when rent authority closes)
+        - Zero out account data and resize to 0 bytes
+        - Account becomes uninitialized and can be garbage collected
+        - See `program-libs/compressible/docs/RENT.md#close-account-distribution` for distribution logic
+
+   d. **Exit without light-system-program CPI**
+
+**Path B: With Compressed Accounts (full transfer operations)**
+   If compressed accounts are involved, execute `process_with_system_program_cpi`:
+
+   a. **Prepare CPI instruction:**
+      - Allocate CPI instruction bytes via `allocate_cpi_bytes`
+      - Create zero-copy CPI instruction struct via `InstructionDataInvokeCpiWithReadOnly::new_zero_copy`
+      - Initialize CPI instruction with proof and context
+      - Create `HashCache` for pubkey hash reuse (Poseidon optimization)
+
+   b. **Process compressed accounts:**
+      - Set input compressed accounts via `set_input_compressed_accounts`:
+        - Hash token data (Poseidon for versions 1-2 with pubkeys pre-hashed to field size, SHA256 for version 3/ShaFlat)
+        - Add merkle context and root indices
+      - Set output compressed accounts via `set_output_compressed_accounts`:
+        - Create new compressed accounts with updated balances
+        - Hash token data and assign to appropriate merkle trees
+
+   c. **Validate transaction balance:**
+      - Run `sum_check_multi_mint` across all mints (up to 5 supported)
+      - Track running sums per mint: compressed inputs + compress operations vs compressed outputs + decompress operations
+      - Verify final sum is zero for each mint (perfect balance)
+
+   d. **Execute based on system account type:**
+
+      **System CPI Path:**
+      If `validated_accounts.system` exists:
+      - Execute `process_token_compression` (src/transfer2/compression/mod.rs) for compress/decompress operations
+      - Extract CPI accounts and tree pubkeys via `validated_accounts.cpi_accounts`
+      - Execute `execute_cpi_invoke` with light-system-program
+      - Execute `close_for_compress_and_close` (src/transfer2/compression/ctoken/compress_and_close.rs) for CompressAndClose operations
+
+      **CPI Context Write Path:**
+      If `validated_accounts.write_to_cpi_context_system` exists:
+      - Validate exactly 4 accounts provided (error: Transfer2CpiContextWriteInvalidAccess if not)
+      - Accounts: [0] light-system-program, [1] fee_payer, [2] cpi_authority_pda, [3] cpi_context
+      - Execute `execute_cpi_invoke` in write-only mode (no tree accounts)
+      - No SOL pool operations allowed (error: Transfer2CpiContextWriteWithSolPool)
+
+**Compression/Decompression Processing Details:**
+
+**Key distinction between compression modes:**
+- **Compress/Decompress:** Only participate in sum checks - tokens are added/subtracted from running sums per mint, ensuring overall balance but no specific output validation
+- **CompressAndClose:** Validates a specific compressed token account exists in outputs that mirrors the account being closed (same mint, amount equals full balance, owner preserved or set to account pubkey, no delegate - delegation not implemented for ctoken accounts)
+
+When compression processing occurs (in both Path A and Path B):
+
+1. **Main routing logic (src/transfer2/compression/mod.rs):**
+   - Function: `process_token_compression`
+   - Iterate through each compression in the compressions array
+   - Get source_or_recipient account from packed accounts
+   - Route to handler based on account owner:
+     - ctoken program → `process_ctoken_compressions` (ctoken/mod.rs)
+     - SPL Token → SPL compression handler
+     - SPL Token 2022 → SPL compression handler
+     - Other → error (InvalidInstructionData)
+
+2. **SPL Token compression/decompression:**
+   - Validate compression mode fields (authority must be 0 for Decompress)
+   - Get mint and token pool PDA from packed accounts
+   - Validate pool PDA derivation matches [mint, pool_index] with provided bump
+   - **For Compress:**
+     - Get authority account from packed accounts
+     - Transfers tokens from user's SPL token account to the token pool PDA via SPL token CPI (authority must be signer, checked by SPL program)
+   - **For Decompress:**
+     - Transfers tokens from the token pool PDA to recipient's SPL token account via SPL token CPI with PDA signer (CPI authority PDA signs)
+
+3. **CToken compression/decompression (src/transfer2/compression/ctoken/):**
+   - **Initial validations:**
+     - Compression mode field validation (authority must be 0 for Decompress mode)
+     - Account ownership verification (must be owned by ctoken program)
+     - Account deserialization as CToken
+     - Mint verification (account mint must match compression mint)
+   - **For Compress:**
+     - Validate authority via `check_authority`:
+       - Check authority is signer (error: InvalidSigner)
+       - If authority == owner: proceed
+       - If authority == delegate: verify delegated amount ≥ compression amount, update delegation
+       - Otherwise: error (OwnerMismatch)
+     - Check sufficient balance (error: ArithmeticOverflow)
+     - Subtracts compression amount from the source ctoken account balance (with overflow protection)
+   - **For Decompress:**
+     - Adds decompression amount to the recipient ctoken account balance (with overflow protection)
+   - **For CompressAndClose:**
+     - **Authority validation:**
+       - Authority must be signer
+       - Authority must be either token account owner OR rent authority (for compressible accounts)
+     - **Design principle: Ownership separation** (see `program-libs/compressible/docs/RENT.md` for detailed rent calculations)
+       - Tokens: Belong to the owner who can compress them freely
+       - Rent exemption + completed epoch rent: Belong to rent authority (who funded them)
+       - Unutilized rent (partial current epoch): Returns to user/destination
+       - Compression incentive: Goes to forester when rent authority compresses
+       - **Compressibility determination** (via `compressible::calculate_rent_and_balance`):
+         - Account becomes compressible when it lacks rent for current epoch + 1
+         - Rent authority can only compress when `is_compressible()` returns true
+         - See `program-libs/compressible/docs/` for complete rent system documentation
+       - When **owner** closes: No compressed output validation required (owner controls their tokens, sum check ensures balance)
+       - When **rent authority** closes: Must validate compressed output exactly preserves owner's tokens
+     - **Compressed token account validation (only when rent authority closes) - MUST exist in outputs with:**
+       - Amount: Must exactly match the full token account balance being compressed
+       - Owner: If compress_to_pubkey flag is false, owner must match original token account owner
+       - Owner: If compress_to_pubkey flag is true, owner must be the token account's pubkey (allows closing accounts owned by PDAs)
+       - Delegate: Must be None (has_delegate=false and delegate=0) - delegates cannot be carried over
+       - Version: Must be ShaFlat (version=3) for security
+       - Version: Must match the version specified in the token account's compressible extension
+     - **Account state updates:**
+       - Token account balance is set to 0
+       - Account is marked for closing after the transaction
+     - **Security guarantee:** Unlike Compress which only adds to sum checks, CompressAndClose ensures the exact compressed account exists, preventing token loss or misdirection
+   - Calculate compressible extension top-up if present (returns Option<u64>)
+   - **Transfer deduplication optimization:**
+     - Collects all transfers into a 40-element array indexed by account
+     - Deduplicates transfers to same account by summing amounts
+     - Executes single `multi_transfer_lamports` CPI with deduplicated transfers (max 40, error: TooManyCompressionTransfers)

+## Withdraw Funding Pool
+
+**discriminator:** 108
+**enum:** `InstructionType::WithdrawFundingPool`
+**path:** programs/compressed-token/program/src/withdraw_funding_pool.rs
+
+**description:**
+1. Withdraws lamports from the rent_sponsor PDA pool to a specified destination account
+2. The rent_sponsor PDA holds funds collected from rent claims and compression incentives
+3. Only the compression_authority from CompressibleConfig can execute withdrawals
+4. **Config validation:** Config must not be inactive (active or deprecated allowed)
+5. The rent_sponsor PDA is derived from ["rent_sponsor", version_bytes, bump] where version comes from CompressibleConfig
+6. Enables protocol operators to manage collected rent and redirect funds for operational needs
+7. The instruction validates PDA derivation matches the config's rent_sponsor
+
+**Instruction data:**
+- First 8 bytes: withdrawal amount (u64, little-endian)
+- Amount must not exceed available pool balance
+
+**Accounts:**
+1. rent_sponsor
+   - (mutable)
+   - The pool PDA holding collected rent and compression incentives
+   - Must match rent_sponsor in CompressibleConfig
+   - Signs the system transfer via PDA seeds
+
+2. compression_authority
+   - (signer)
+   - Authority authorized to withdraw from pool
+   - Must match compression_authority in CompressibleConfig
+   - Only this authority can withdraw funds
+
+3. destination
+   - (mutable)
+   - Account to receive the withdrawn lamports
+   - Can be any valid Solana account
+
+4. system_program
+   - (non-mutable)
+   - System program for lamport transfer
+   - Required for system_instruction::transfer
+
+5. config
+   - (non-mutable)
+   - CompressibleConfig account containing pool configuration
+   - Owner must be Registry program (Lighton6oQpVkeewmo2mcPTQQp7kYHr4fWpAgJyEmDX)
+   - Must not be in inactive state
+   - Used to validate authorities and PDA derivation
+
+**Instruction Logic and Checks:**
+
+1. **Parse instruction data:**
+   - Extract amount from first 8 bytes as u64 little-endian
+   - Error if instruction data length < 8 bytes
+
+2. **Validate and parse accounts:**
+   - Parse all required accounts with correct mutability
+   - Verify compression_authority is signer
+   - Parse and validate CompressibleConfig:
+     - Deserialize using parse_config_account helper
+     - Check config is not inactive (validate_not_inactive)
+   - Verify compression_authority matches config
+   - Verify rent_sponsor matches config
+   - Extract rent_sponsor_bump and version for PDA derivation
+
+3. **Verify sufficient funds:**
+   - Get current pool balance from rent_sponsor.lamports()
+   - Check pool_lamports >= requested amount
+   - Error if insufficient funds
+
+4. **Execute transfer:**
+   - Create system_instruction::transfer from rent_sponsor to destination
+   - Prepare PDA signer seeds: ["rent_sponsor", version_bytes, bump]
+   - Invoke system program with PDA as signer using invoke_signed
+   - Transfer specified amount to destination
+
+**Errors:**
+
+- `ProgramError::InvalidInstructionData` (error code: 3) - Instruction data length < 8 bytes or cannot parse amount from bytes
+- `ProgramError::InvalidSeeds` (error code: 14) - compression_authority or rent_sponsor doesn't match CompressibleConfig
+- `ProgramError::InvalidAccountData` (error code: 4) - CompressibleConfig deserialization fails or invalid discriminator
+- `ProgramError::InsufficientFunds` (error code: 6) - Pool balance less than requested withdrawal amount (available balance shown in error message)
+- `AccountError::NotEnoughAccountKeys` (error code: 12020) - Missing required accounts
+- `AccountError::InvalidSigner` (error code: 12015) - compression_authority is not a signer
+- `AccountError::AccountNotMutable` (error code: 12008) - rent_sponsor or destination is not mutable
+- `CompressibleError::InvalidState` (error code: 19002) - CompressibleConfig is in inactive state

+# Registry Program - Wrapper Instructions
+
+## Overview
+
+The registry program wraps underlying program instructions (primarily Account Compression) with access control, forester eligibility checks, and work tracking. This pattern ensures decentralized operations are properly authorized and tracked for rewards.
+
+## Core Pattern
+
+Every wrapper instruction:
+1. **Loads target account** - deserializes account data to access metadata
+2. **Checks forester eligibility** - validates authority and tracks work performed
+3. **Executes CPI** - delegates to target program with PDA signer
+
+```rust
+pub fn wrapper_instruction<'info>(
+    ctx: Context<'_, '_, '_, 'info, WrapperContext<'info>>,
+    bump: u8,           // CPI authority PDA bump
+    data: Vec<u8>,      // Serialized instruction data to pass through
+) -> Result<()> {
+    // 1. Load account data (deserialization method depends on account type)
+    let account = AccountType::from_account_info(&ctx.accounts.target_account)?;
+    
+    // 2. Check forester eligibility and track work
+    check_forester(
+        &account.metadata,
+        ctx.accounts.authority.key(),
+        ctx.accounts.target_account.key(),
+        &mut ctx.accounts.registered_forester_pda,
+        work_units,  // Determined by operation type
+    )?;
+    
+    // 3. Delegate to CPI processing function
+    process_wrapper_cpi(&ctx, bump, data)
+}
+```
+
+### Examples of Wrapper Instructions
+
+**Batched operations:**
+- `batch_update_address_tree` - Updates multiple addresses in batches
+- `batch_append` - Appends batched leaves to output queue
+- `batch_nullify` - Nullifies batched leaves from input queue
+
+**Tree management:**
+- `rollover_state_merkle_tree_and_queue` - Migrates to new tree when full
+- `rollover_batched_address_merkle_tree` - Rolls over batched address tree
+- `initialize_batched_state_merkle_tree` - Creates new batched tree
+
+**Single operations:**
+- `nullify` - Nullifies individual leaves
+- `update_address_merkle_tree` - Updates single address
+- `migrate_state` - Migrates leaves between trees
+
+## Account Context
+
+Standard accounts needed for wrapper instructions:
+
+```rust
+#[derive(Accounts)]
+pub struct WrapperContext<'info> {
+    /// Optional: forester PDA for network trees
+    #[account(mut)]
+    pub registered_forester_pda: Option<Account<'info, ForesterEpochPda>>,
+    
+    /// Transaction authority
+    pub authority: Signer<'info>,
+    
+    /// PDA that signs CPIs to Account Compression
+    #[account(seeds = [CPI_AUTHORITY_PDA_SEED], bump)]
+    pub cpi_authority: AccountInfo<'info>,
+    
+    /// Program access control
+    pub registered_program_pda: AccountInfo<'info>,
+    
+    /// Target program
+    pub account_compression_program: Program<'info, AccountCompression>,
+    
+    /// Event logging
+    pub log_wrapper: UncheckedAccount<'info>,
+    
+    /// Target account being operated on
+    #[account(mut)]
+    pub target_account: AccountInfo<'info>,
+    
+    // Additional operation-specific accounts...
+}
+```
+
+## CPI Processing
+
+The processing function creates the CPI with PDA signer:
+
+```rust
+pub fn process_wrapper_cpi(
+    ctx: &Context<WrapperContext>,
+    bump: u8,
+    data: Vec<u8>,
+) -> Result<()> {
+    // Setup PDA signer seeds
+    let bump = &[bump];
+    let seeds = [CPI_AUTHORITY_PDA_SEED, bump];
+    let signer_seeds = &[&seeds[..]];
+    
+    // Prepare CPI accounts (structure matches target program's instruction)
+    let accounts = target_program::cpi::accounts::InstructionAccounts {
+        authority: ctx.accounts.cpi_authority.to_account_info(),
+        target: ctx.accounts.target_account.to_account_info(),
+        registered_program_pda: Some(ctx.accounts.registered_program_pda.clone()),
+        log_wrapper: ctx.accounts.log_wrapper.to_account_info(),
+        // Map remaining accounts from context
+    };
+    
+    // Execute CPI with PDA as signer
+    let cpi_ctx = CpiContext::new_with_signer(
+        ctx.accounts.target_program.to_account_info(),
+        accounts,
+        signer_seeds,
+    );
+    
+    // Call target program's instruction with data
+    target_program::cpi::instruction_name(cpi_ctx, data)
+}
+```
+
+## Forester Eligibility
+
+The `check_forester` function validates operation authority:
+
+- **With forester PDA**: Validates epoch registration, checks eligibility, tracks work, requires network fee
+- **Without forester PDA**: Checks if authority matches tree's designated forester (private trees)
+
+## Adding New Wrapper Instructions
+
+### Step 1: Create Account Context
+Create `src/account_compression_cpi/new_operation.rs`:
+- Define `NewOperationContext` struct with required accounts
+- Import necessary types and constants
+
+### Step 2: Implement CPI Processing
+Add `process_new_operation` function:
+- Setup PDA signer seeds
+- Map accounts to target program's expected structure
+- Execute CPI with signer
+
+### Step 3: Add Instruction Handler
+In `lib.rs`:
+- Load account to get metadata (method varies by account type)
+- Determine work units (batch size, DEFAULT_WORK_V1, or custom)
+- Call `check_forester` with appropriate parameters
+- Call processing function
+
+### Step 4: Export Module
+- Add `pub mod new_operation;` to `account_compression_cpi/mod.rs`
+- Add `pub use new_operation::*;` export
+- Import in `lib.rs` with `use` statement
+
+## Key Implementation Details
+
+### Work Units
+- **Batch operations**: Use `account.queue_batches.batch_size`
+- **Single operations**: Use `DEFAULT_WORK_V1` constant
+- **Custom**: Calculate based on operation complexity
+
+### Account Loading
+- **Batched accounts**: `BatchedMerkleTreeAccount::type_from_account_info()`
+- **Regular accounts**: `ctx.accounts.account.load()?.metadata`
+- **Raw deserialization**: Custom deserialization logic
+
+### Data Parameter
+- Contains serialized instruction data for target program
+- Passed through unchanged to maintain compatibility
+- Target program handles deserialization
+
+### Error Handling
+- `InvalidSigner`: Authority not authorized
+- `InvalidNetworkFee`: Fee mismatch
+- `ForesterDefined/Undefined`: Incorrect forester setup
