+# Plan: Deno Compatibility for MadBase Edge Functions
+
+## Problem Statement
+Currently, MadBase executes Edge Functions as WASM modules via `wasmtime`. Supabase-compatible Edge Functions (like those in `accountaflow`) are written in TypeScript and target a Deno environment. Migrating these requires 1:1 compatibility for the `Deno` namespace, ES modules, and standard web APIs (Fetch, Request, Response).
+
+## Proposed Architecture
+
+### 1. Dual-Runtime Strategy
+Extend the `functions` crate to support two runtimes:
+- **WasmRuntime**: Existing `wasmtime` based executor for compiled modules.
+- **DenoRuntime**: A new V8-based executor utilizing `deno_core` and `deno_runtime`.
+
+### 2. Runtime Detection
+The gateway should detect the function type:
+- **DenoRuntime (V8)**: Files ending in `.ts` or `.js`. Recommended for standard Edge Functions due to JIT-optimized performance.
+- **WasmRuntime (Wasmtime)**: Native WASM binaries (Rust, Go, C++). Best for specialized, high-performance logic or pre-compiled modules.
+
+
+## Implementation Steps
+
+### Phase 1: Core Integration
+- Add `deno_core` and `deno_runtime` dependencies to `madbase/functions/Cargo.toml`.
+- Create `functions/src/deno_runtime.rs`.
+- Implement `execute_script(code: String, payload: Value)` using `JsRuntime`.
+
+### Phase 2: Supabase Environment Compatibility
+- **Process Environment**: Inject `SUPABASE_URL`, `SUPABASE_ANON_KEY`, and `SUPABASE_SERVICE_ROLE_KEY`.
+- **Global Objects**: Implement a shim for `Deno.serve` to capture the incoming request and route it to the script's handler.
+- **Header Parsing**: Ensure standard headers (`apikey`, `Authorization`) are passed through.
+
+### Phase 3: Module Resolution
+- Implement a `ModuleLoader` that handles imports from `https://esm.sh/`.
+- Support local imports from a shared functions directory (like `_shared`).
+
+## API Changes
+
+### Gateway
+Modify `POST /functions/v1` to accept `type: "typescript" | "wasm"`. Default to "typescript" for source code.
+
+### Deployment Table
+Update the `functions` table schema in the control plane to store the runtime type.
+
+## Verification Plan
+
+### Automated Tests
+1. **Hello World Test**: Deploy a simple `.ts` function and verify the output.
+2. **Supabase Client Test**: Deploy a function that imports `@supabase/supabase-js` from `esm.sh` and queries the MadBase Data API.
+3. **Environment Variable Test**: Verify `Deno.env.get` returns expected MadBase configuration.
+
+### Manual Verification
+1. Attempt to deploy the `invite-staff` function from `accountaflow` directly to MadBase.
+2. Verify cross-organization invitation logic works.
