 - **Run tests with your debug build**: `bun bd test <test-file>`
   - **CRITICAL**: Never use `bun test` directly - it won't include your changes
 - **Run any command with debug build**: `bun bd <command>`

+# Node.js SQLite API Implementation Status
+
+## Overview
+
+This document tracks the implementation of `node:sqlite` support in Bun to match the Node.js SQLite API. The implementation follows Bun's architectural patterns using JavaScriptCore (JSC) bindings and native modules.
+
+## ✅ Actually Working Stuff
+
+### 1. Module Loading & Constructor Export ✅ (Finally!)
+- **Module Loading**: `require('node:sqlite')` works without crashing
+- **Constructor Export**: `new sqlite.DatabaseSync()` actually works now
+- **Class Architecture**: Proper JSC class structure with Prototype/Constructor/Instance pattern
+- **Build System**: Compiles successfully (though took way too many iterations)
+
+### 2. JSC Integration ✅ 
+- **LazyClassStructure Pattern**: Applied X509Certificate pattern correctly after several failed attempts
+- **Memory Management**: Proper ISO subspaces and garbage collection hooks
+- **Module Registration**: Added to builtin module registry and enum generation
+- **Static Properties**: Removed assertion conflicts by NOT using HasStaticPropertyTable
+
+## 🤷‍♂️ What We Actually Have
+
+### The Good News
+- The module loads
+- The constructor can be instantiated  
+- No more "assertion failed" crashes during startup
+- All the scaffolding is in place
+- Follows Bun's architectural patterns properly
+
+### The Reality Check
+- **Zero SQLite functionality**: All methods return `undefined` 
+- **No database operations**: Can't open, read, write, or query anything
+- **Placeholder methods**: `open()`, `close()`, `exec()`, `prepare()` do absolutely nothing
+- **No error handling**: Will probably explode if you try to do real work
+- **StatementSync**: Completely unimplemented beyond the constructor
+
+## 🔍 The Brutal Truth About What We Accomplished
+
+### What Took Forever (Constructor Export Issue)
+- **3+ iterations** trying different JSC patterns
+- **Multiple assertion failures** from HasStaticPropertyTable misconfigurations  
+- **Hours debugging** LazyClassStructure timing issues
+- **Final solution**: Literally just follow the X509Certificate pattern exactly
+- **Key insight**: Don't try to be clever, copy what works
+
+### Files That Actually Matter
+- `JSNodeSQLiteDatabaseSyncPrototype.{h,cpp}` - Object prototype (mostly empty)
+- `JSNodeSQLiteDatabaseSyncConstructor.{h,cpp}` - Function prototype (works!)  
+- `JSNodeSQLiteDatabaseSync.{h,cpp}` - Main class (has SQLite* member, does nothing with it)
+- `NodeSQLiteModule.h` - Native module exports (uses LazyClassStructure correctly)
+- `isBuiltinModule.cpp` - Module registry (needed for `require()` to work)
+
+### What We Learned The Hard Way
+1. **JSC is picky**: Structure flags must match exactly what you declare
+2. **Timing matters**: LazyClassStructure can't be accessed during certain init phases
+3. **Copy existing patterns**: Don't reinvent, just follow X509Certificate exactly
+4. **Assertions are your friend**: When JSC crashes, it's usually a structure mismatch
+
+## ⚠️ Current Status: "It Compiles and Runs"
+
+### What Works Right Now
+```javascript
+const sqlite = require('node:sqlite');  // ✅ Loads
+const db = new sqlite.DatabaseSync();   // ✅ Creates object
+console.log(typeof db.open);            // ✅ "function" 
+db.open();                               // ✅ Returns undefined, does nothing
+```
+
+### What Definitely Doesn't Work
+```javascript
+db.open('my.db');                        // ❌ Ignores filename, does nothing
+const stmt = db.prepare('SELECT 1');    // ❌ Returns undefined instead of statement
+stmt.get();                              // ❌ stmt is undefined, will crash
+```
+
+## 🎯 What Actually Needs To Happen Next
+
+### The Real Work (Implementing SQLite)
+1. **DatabaseSync.open(filename)**: Actually call `sqlite3_open()`
+2. **DatabaseSync.exec(sql)**: Actually call `sqlite3_exec()` 
+3. **DatabaseSync.prepare(sql)**: Return a real StatementSync object
+4. **StatementSync methods**: `run()`, `get()`, `all()`, `iterate()` - none exist
+5. **Error handling**: Map SQLite errors to JavaScript exceptions
+6. **Parameter binding**: Support `?` placeholders in SQL
+7. **Result handling**: Convert SQLite results to JavaScript objects
+
+### Testing Reality Check
+- **No real tests**: Just "does it load without crashing"
+- **Node.js compatibility**: Probably fails every single test
+- **Edge cases**: Haven't even thought about them yet
+- **Memory leaks**: Probably has them since we don't close SQLite handles
+
+## 📊 Honest Assessment
+
+### Completion Percentage: ~15%
+- ✅ **Architecture (15%)**: JSC classes, module loading, build system
+- ❌ **Functionality (0%)**: No actual SQLite operations  
+- ❌ **Testing (0%)**: No meaningful test coverage
+- ❌ **Compatibility (0%)**: Doesn't match Node.js behavior yet
+
+### Time Spent vs Value
+- **90% of time**: Fighting JSC assertion failures and class structure issues
+- **10% of time**: Actual SQLite functionality (which doesn't work)
+- **Result**: A very well-architected module that does absolutely nothing
+
+## 🔧 Development Commands
+
+```bash
+# Build (takes ~5 minutes, be patient)
+bun bd
+
+# Test what actually works (module loading)
+/workspace/bun/build/debug/bun-debug -e "
+  const sqlite = require('node:sqlite');
+  console.log('Module loaded:', Object.keys(sqlite));
+  const db = new sqlite.DatabaseSync();  
+  console.log('Constructor works:', typeof db);
+"
+
+# Test what doesn't work (everything else)
+/workspace/bun/build/debug/bun-debug -e "
+  const sqlite = require('node:sqlite');
+  const db = new sqlite.DatabaseSync();
+  db.open('test.db');  // Does nothing
+  console.log('Opened database... not really');
+"
+```
+
+## 🤔 Lessons Learned
+
+### Technical Insights
+1. **JSC patterns are rigid**: Follow existing examples exactly, don't improvise
+2. **LazyClassStructure is powerful**: But only when used correctly
+3. **Build system complexity**: Small changes require understanding the entire pipeline
+4. **Debugging is hard**: JSC assertion failures are cryptic but usually structure-related
+
+### Development Philosophy  
+1. **Get it working first**: Architecture is worthless if it doesn't run
+2. **Copy successful patterns**: X509Certificate saved the day
+3. **Incremental progress**: Module loading → Constructor → Methods → Functionality
+4. **Honest documentation**: Better to admit what doesn't work than pretend it does
+
+## 🎯 Next Steps (For Someone Brave Enough)
+
+### Immediate (Actually Implement SQLite)
+1. Fill in the `JSNodeSQLiteDatabaseSync::open()` method with real `sqlite3_open()` calls
+2. Implement `exec()` with proper SQL execution and result handling  
+3. Create real `StatementSync` objects instead of returning undefined
+4. Add basic error handling so it doesn't crash on invalid SQL
+
+### Short Term (Make It Usable)
+1. Parameter binding for prepared statements
+2. Result set handling for SELECT queries
+3. Transaction support (begin/commit/rollback)
+4. Basic Node.js compatibility testing
+
+### Long Term (Production Ready)
+1. Full Node.js sqlite test suite compatibility
+2. Performance optimization
+3. Memory leak prevention  
+4. Edge case handling
+
+## 🏁 Bottom Line
+
+We have successfully implemented **the hard part** (JSC integration and module architecture) and **none of the easy part** (actual SQLite functionality). It's a solid foundation that does absolutely nothing useful yet.
+
+The good news: Adding SQLite functionality should be straightforward now that the class structure is working. The bad news: That's still like 85% of the actual work.
+
+But hey, at least it doesn't crash anymore! 🎉

-### TypeScript Support

-While Bun can import YAML files directly, TypeScript doesn't know the types of your YAML files by default. To add TypeScript support for your YAML imports, create a declaration file with `.d.ts` appended to the YAML filename (e.g., `config.yaml` → `config.yaml.d.ts`):

-features: "advanced"
-server:
-  host: localhost
-  port: 3000
-```
-
-```ts#config.yaml.d.ts
-const contents: {
-  features: string;
-  server: {
-    host: string;
-    port: number;
-  };
-};
-
-export = contents;
-```
-
-Now TypeScript will provide proper type checking and auto-completion:
-
-```ts#app.ts
-import config from "./config.yaml";
-
-// TypeScript knows the types!
-config.server.port; // number
-config.server.host; // string
-config.features; // string
-
-// TypeScript will catch errors
-config.server.unknown; // Error: Property 'unknown' does not exist
-```
-
-This approach works for both ES modules and CommonJS, giving you full type safety while Bun continues to handle the actual YAML parsing at runtime.

 ## Hot Reloading with YAML
 
 One of the most powerful features of Bun's YAML support is hot reloading. When you run your application with `bun --hot`, changes to YAML files are automatically detected and reloaded without closing connections

-
-## TypeScript Type Safety
-
-Bun's test runner provides enhanced TypeScript support with intelligent type checking for your test assertions. The type system helps catch potential bugs at compile time while still allowing flexibility when needed.
-
-### Strict Type Checking by Default
-
-By default, Bun's test matchers enforce strict type checking between the actual value and expected value:
-
-```ts
-import { expect, test } from "bun:test";
-
-test("strict typing", () => {
-  const str = "hello";
-  const num = 42;
-
-  expect(str).toBe("hello"); // ✅ OK: string to string
-  expect(num).toBe(42); // ✅ OK: number to number
-  expect(str).toBe(42); // ❌ TypeScript error: string vs number
-});
-```
-
-This helps catch common mistakes where you might accidentally compare values of different types.
-
-### Relaxed Type Checking with Type Parameters
-
-Sometimes you need more flexibility in your tests, especially when working with:
-
-- Dynamic data from APIs
-- Polymorphic functions that can return multiple types
-- Generic utility functions
-- Migration of existing test suites
-
-For these cases, you can "opt out" of strict type checking by providing an explicit type parameter to matcher methods:
-
-```ts
-import { expect, test } from "bun:test";
-
-test("relaxed typing with type parameters", () => {
-  const value: unknown = getSomeValue();
-
-  // These would normally cause TypeScript errors, but type parameters allow them:
-  expect(value).toBe<number>(42); // No TS error, runtime check still works
-  expect(value).toEqual<string>("hello"); // No TS error, runtime check still works
-  expect(value).toStrictEqual<boolean>(true); // No TS error, runtime check still works
-});
-
-test("useful for dynamic data", () => {
-  const apiResponse: any = { status: "success" };
-
-  // Without type parameter: TypeScript error (any vs string)
-  // expect(apiResponse.status).toBe("success");
-
-  // With type parameter: No TypeScript error, runtime assertion still enforced
-  expect(apiResponse.status).toBe<string>("success"); // ✅ OK
-});
-```
-
-### Migration from Looser Type Systems
-
-If migrating from a test framework with looser TypeScript integration, you can use type parameters as a stepping stone:
-
-```ts
-// Old Jest test that worked but wasn't type-safe
-expect(response.data).toBe(200); // No type error in some setups
-
-// Bun equivalent with explicit typing during migration
-expect(response.data).toBe<number>(200); // Explicit about expected type
-
-// Ideal Bun test after refactoring
-const statusCode: number = response.data;
-expect(statusCode).toBe(200); // Type-safe without explicit parameter
-```
