+# 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

+# Example Usage
+
+## Basic Usage
+
+```rust
+#[add_compressible_instructions(UserRecord, GameSession)]
+#[program]
+pub mod my_program {
+    use super::*;
+    // ... your instructions
+}
+```
+
+## External File Module Support - NEW APPROACH! 🚀
+
+For complex projects with multi-file structures (like Raydium CP-Swap), you can now use the new `derive(Compressible)` approach for **completely automatic seed detection**:
+
+### Step 1: Add derive(Compressible) to your instruction struct
+
+```rust
+// instructions/initialize.rs
+use anchor_lang::prelude::*;
+use light_sdk_macros::Compressible;  // Import the derive macro
+
+#[derive(Accounts, Compressible)]  // ← Add Compressible derive!
+pub struct Initialize<'info> {
+    #[account(mut)]
+    pub creator: Signer<'info>,
+
+    #[account(
+        init,
+        seeds = [
+            POOL_SEED.as_bytes(),
+            amm_config.key().as_ref(),
+            token_0_mint.key().as_ref(),
+            token_1_mint.key().as_ref(),
+        ],
+        bump,
+        payer = creator,
+        space = PoolState::LEN
+    )]
+    pub pool_state: Box<Account<'info, PoolState>>,  // ← Automatically detected!
+
+    pub amm_config: Box<Account<'info, AmmConfig>>,
+    pub token_0_mint: Box<InterfaceAccount<'info, Mint>>,
+    pub token_1_mint: Box<InterfaceAccount<'info, Mint>>,
+    // ... other fields
+}
+```
+
+### Step 2: Import and use normally
+
+```rust
+// lib.rs
+pub use crate::instructions::initialize::Initialize;  // Import your instruction struct
+pub use crate::states::PoolState;
+
+#[add_compressible_instructions(PoolState)]  // ← Works automatically now!
+#[program]
+pub mod raydium_cp_swap {
+    use super::*;
+
+    pub fn initialize(ctx: Context<Initialize>, ...) -> Result<()> {
+        // Your initialization logic
+    }
+
+    // ... other instructions
+}
+```
+
+**That's it!** The macro automatically:
+
+- ✅ Finds the `Initialize` struct with `derive(Compressible)`
+- ✅ Extracts the exact seeds from the `#[account(init, seeds = [...], bump)]` attribute
+- ✅ Generates compression instructions using those seeds
+- ✅ Works with any account types and seed patterns
+- ✅ No hardcoded patterns or guessing required
+
+## Multiple Account Types
+
+You can use the same approach for multiple account types:
+
+```rust
+// Different instruction structs with different account types
+#[derive(Accounts, Compressible)]
+pub struct CreateUser<'info> {
+    #[account(init, seeds = [b"user", authority.key().as_ref()], bump)]
+    pub user_account: Account<'info, UserAccount>,
+    pub authority: Signer<'info>,
+}
+
+#[derive(Accounts, Compressible)]
+pub struct InitializeVault<'info> {
+    #[account(init, seeds = [b"vault", mint.key().as_ref()], bump)]
+    pub vault: Account<'info, TokenVault>,
+    pub mint: Account<'info, Mint>,
+}
+
+// All work automatically
+#[add_compressible_instructions(PoolState, UserAccount, TokenVault)]
+#[program]
+pub mod my_program {
+    // ...
+}
+```
+
+## Generated Instructions
+
+For each account type, the macro generates:
+
+- **`compress_{type_name}`** - Compresses the PDA using the exact same seeds
+- **`decompress_accounts_idempotent`** - Batch decompress multiple accounts
+- **`initialize_compression_config`** - Set up compression configuration
+- **`update_compression_config`** - Update compression settings
+
+## Key Benefits of the New Approach
+
+1. **🎯 100% Accurate**: Uses the exact seeds from your instruction structs
+2. **🔄 Zero Duplication**: No need to specify seeds twice
+3. **🛡️ Type Safe**: Compile-time verification of account types
+4. **📁 Multi-File Support**: Works with any project structure
+5. **🚀 Future Proof**: Supports any seed patterns, not just common ones
+6. **⚡ Automatic**: No configuration or setup required
+
+## Migration from Previous Versions
+
+If you were using the old pattern-matching approach, simply:
+
+1. Add `#[derive(Compressible)]` to your instruction structs
+2. Remove any workaround code or manual seed specifications
+3. The macro now works automatically!
+
+```diff
+// Before (workarounds needed)
+- #[add_compressible_instructions(PoolState@[POOL_SEED.as_bytes(), ...])]
+
+// After (completely automatic)
++ #[derive(Accounts, Compressible)]
++ pub struct Initialize<'info> { /* seeds automatically detected */ }
++ #[add_compressible_instructions(PoolState)]
+```
+
+## Error Messages
+
+If you forget to add `derive(Compressible)`, you'll get helpful guidance:
+
+```
+No seed registry found for type 'PoolState'.
+
+To use this type with #[add_compressible_instructions], you need to:
+
+1. Apply #[derive(Compressible)] to an instruction struct that initializes this account type:
+
+#[derive(Accounts, Compressible)]
+pub struct Initialize<'info> {
+    #[account(init, seeds = [...], bump)]
+    pub pool_state: Account<'info, PoolState>,
+}
+
+2. Make sure the instruction struct is imported in the same module where #[add_compressible_instructions] is used:
+
+pub use crate::instructions::initialize::Initialize;
+```
+
+This approach completely solves the external file module limitation while being more robust and user-friendly than any pattern matching could be!

+# 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.
