+# BEX Engine v6 — WASM Plugin Engine
+
+A **production-grade WASM/Wasmtime Component Model** plugin engine built in Rust. BEX enables sandboxed, deterministic plugin execution using WebAssembly components with WIT interface definitions. Designed for media streaming, metadata, and content provider applications with a **Pure C ABI** integration layer — no cxx dependency.
+
+## What's New in v6
+
+This version incorporates all fixes from the QuickJS Integration Plan v3 review:
+
+### Critical Bug Fixes
+- **`eval-js` now accepts `input` parameter** — user data is safely injected as a global variable instead of being concatenated into JS source code, eliminating code injection vulnerabilities
+- **`call-js-fn` now accepts `fn-source` parameter** — functions are registered and auto-re-registered when source changes, eliminating the broken `track_functions` text parser
+- **`TextEncoder`/`TextDecoder` are now spec-correct UTF-8** — properly handles CJK characters, emoji, and all Unicode code points
+- **`crypto.getRandomValues` uses Rust-backed CSPRNG** — `rand::thread_rng()` instead of `Math.random()`
+- **`crypto.subtle` is now fully implemented** — SHA-1/256/384/512, AES-CBC encrypt/decrypt, HMAC-SHA256/512, PBKDF2, all in pure JS with immediate-resolved Promises
+- **`args_json` is passed as a string, not eval'd** — eliminates JS injection attack vector
+- **Pool dispatch is non-blocking** — uses `try_send` instead of blocking `send`, returns `PoolBusy` instead of hanging Wasmtime threads
+- **Pool shutdown uses SeqCst ordering** — fixes race condition on ARM/Apple Silicon
+
+### Missing Features Now Implemented
+- **`console.log` routes to Rust tracing** — no longer silently dropped
+- **`setTimeout`/`setInterval` call callbacks synchronously** — no longer silently skipped
+- **`clear-js-fn` WIT function** — allows unregistering JS functions when cipher rotates
+- **`JsPoolConfig` wired into `EngineConfig`** — JS pool settings are configurable from engine config
+
+### Design Improvements
+- **Idle context eviction throttled to 30-second intervals** — reduces overhead from checking on every loop iteration
+- **`apply_fn` helper removed** — `func.call((args_json,))` used directly
+- **`max_stack_bytes` configurable via `JsPoolConfig`** — default 512KB
+- **All compiler warnings fixed** — unused imports, dead code, unused variables
+- **`atob`/`btoa` are Rust-backed** — correct Latin-1 handling via base64 crate
+- **Additional polyfills** — `URL`, `URLSearchParams`, `performance.now()`, `structuredClone`, `navigator`, `location`, `queueMicrotask`

+
+### Core Design Principles
+
+1. **WASM-Only**: All plugins run as WebAssembly components via Wasmtime — no native plugins, no dual-mode engine
+2. **Component Model**: Uses Wasmtime's Component Model with WIT interface definitions for type-safe host-guest communication
+3. **Callback-Driven**: C++ backend submits requests via `bex_submit_*()`, receives results via a C function pointer callback (`BexResultCallback`) invoked from a background Tokio thread. No polling, no event queue, no drain pattern.
+4. **Self-Describing IDs**: The engine treats IDs as opaque strings — it does not know or care what they mean. Each plugin defines its own ID format and parses IDs internally. For example, `get_servers` takes a single `id` parameter; the plugin parses `slug$ep=1$sub=1$dub=0` because it knows its own encoding scheme. There is no `episode_id` parameter anywhere in the engine.
+5. **Sandboxed Execution**: Fuel-based metering, stack limits, epoch-based timeouts, and capability-based host APIs
+6. **Lane-Based Scheduling**: Three concurrency lanes — Control (1), User (4), Background (2) — with semaphores, plus global WASM (4) and HTTP (8) permit limits
+7. **Cancellation**: Each request gets a `CancellationToken`; cancel via `bex_cancel_request()`
+8. **Pure C ABI**: The Rust engine exports `extern "C"` functions matching `bex_engine.h`. No cxx, no bridge codegen, no special build steps. Link the Rust static/shared library natively.

+
+## Pure C ABI
+
+The Rust engine exposes a **Pure C ABI** through `bex_engine.h`. No cxx, no code generation, no bridge crate. The Rust library compiles as both `cdylib` and `staticlib`, and CMake links it natively.
+
+### How It Works
+
+1. C++ calls `bex_submit_search(engine, plugin_id, query, callback, user_data)`
+2. Rust spawns a Tokio task that does the work
+3. On completion, Rust invokes `callback(user_data, request_id, success, payload, len)` from the Tokio background thread
+4. C++ receives the result in the callback and can parse/copy the payload before the callback returns
+
+### C++ Integration Example
+
+```cpp
+#include "bex_engine.h"
+
+// 1. Define a callback handler
+extern "C" void on_result(void* user_data, uint64_t req_id,
+                          bool success, const uint8_t* payload, size_t len) {
+    auto* promise = static_cast<std::promise<std::string>*>(user_data);
+    if (success) {
+        promise->set_value(std::string(reinterpret_cast<const char*>(payload), len));
+    } else {
+        promise->set_exception(std::make_exception_ptr(
+            std::runtime_error(std::string(reinterpret_cast<const char*>(payload), len))));
+    }
+}
+
+// 2. Create engine
+BexEngine* engine = bex_engine_new("/path/to/data");
+
+// 3. Submit async requests — returns request_id immediately
+std::promise<std::string> promise;
+uint64_t req1 = bex_submit_home(engine, "bex.gogoanime", on_result, &promise);
+uint64_t req2 = bex_submit_search(engine, "bex.gogoanime", "one piece", on_result, &promise);
+uint64_t req3 = bex_submit_info(engine, "bex.gogoanime", "one-piece", on_result, &promise);
+uint64_t req4 = bex_submit_servers(engine, "bex.gogoanime", "one-piece$ep=1$sub=1$dub=0",
+                                    on_result, &promise);
+
+// 4. Wait for results (or use the callback in your event loop)
+std::string result = promise.get_future().get();
+
+// 5. Cancel a request
+bex_cancel_request(engine, req2);
+
+// 6. Plugin management (synchronous)
+bex_engine_install(engine, "/path/to/plugin.bex");
+bex_engine_uninstall(engine, "bex.gogoanime");
+BexPluginInfoList plugins = bex_engine_list_plugins(engine);
+bex_plugin_info_list_free(plugins);
+
+// 7. API key management (synchronous)
+bex_engine_secret_set(engine, "bex.imdb", "api-key", "your-key");
+
+// 8. Shutdown
+bex_engine_free(engine);

+## Quick Start
+
+### Prerequisites
+
+- Rust toolchain (stable)
+- `wasm-tools` CLI: `cargo install wasm-tools-cli`
+- C++17 compiler (for C++ CLI / integration)
+- CMake 3.16+ (for C++ CLI / integration)
+
+### Build the Engine
+
+```bash
+# Build the Rust engine and CLI
+cargo build --release
+
+# Build and pack all plugins (compile → component convert → pack)
+bash build-plugins.sh
+
+# Build the C++ CLI with CMake
+cd cpp-cli && mkdir build && cd build
+cmake .. -DCMAKE_BUILD_TYPE=Release
+make -j$(nproc)
+```
+
+### Build a Single Plugin (Manual)
+
+Plugins are built in three steps: compile to WASM, convert to a component, then pack.
+
+```bash
+# Step 1: Compile to wasm32-wasip1
+cargo build -p bex-gogoanime --target wasm32-wasip1 --release
+
+# Step 2: Convert to a WASM Component (requires wasm-tools + WASI adapter)
+wasm-tools component new \
+    target/wasm32-wasip1/release/bex_gogoanime.wasm \
+    -o target/components/bex-gogoanime.component.wasm \
+    --adapt ~/.cargo/registry/src/index.crates.io-*/wasi-preview1-component-adapter-provider-*/artefacts/wasi_snapshot_preview1.reactor.wasm
+
+# Step 3: Pack into a .bex package
+cargo run -p bex-cli --release -- pack \
+    dist/bex-gogoanime.yaml \
+    target/components/bex-gogoanime.component.wasm \
+    dist/bex-gogoanime.bex
+```
+
+### Install and Use
+
+```bash
+# Install a plugin
+cargo run -p bex-cli --release -- install dist/bex-gogoanime.bex
+
+# List installed plugins
+cargo run -p bex-cli --release -- list
+
+# Get detailed plugin info
+cargo run -p bex-cli --release -- plugin-info bex.gogoanime
+```
+
+## Plugin Management
+
+### Rust CLI
+
+```bash
+# Install / uninstall
+bex install dist/bex-gogoanime.bex
+bex uninstall bex.gogoanime
+
+# List installed plugins
+bex list
+
+# Show detailed plugin info (capabilities, enabled state, etc.)
+bex plugin-info bex.gogoanime
+
+# Enable / disable
+bex enable bex.gogoanime
+bex disable bex.gogoanime
+
+# Inspect a .bex package without installing
+bex inspect dist/bex-gogoanime.bex
+
+# Engine stats
+bex stats
+```
+
+### C++ CLI
+
+```bash
+# Install / uninstall
+./bexcli install dist/bex-gogoanime.bex
+./bexcli uninstall bex.gogoanime
+
+# List plugins (with capabilities column)
+./bexcli list
+
+# Detailed plugin info (includes API keys list)
+./bexcli info-plugin bex.gogoanime
+
+# Enable / disable
+./bexcli enable bex.gogoanime
+./bexcli disable bex.gogoanime
+
+# Engine stats
+./bexcli stats
+```
+
+## API Key / Secret Management
+
+The engine provides per-plugin secret storage backed by Redb. Secrets are scoped to a plugin ID and are accessible to the plugin at runtime via the `secrets` WIT interface. This is the mechanism for storing API keys, tokens, and other credentials that plugins need.
+
+### Rust CLI
+
+```bash
+# Set an API key
+bex set-key bex.imdb api-key "your-api-key-here"
+
+# Get an API key value
+bex get-key bex.imdb api-key
+
+# Delete an API key
+bex delete-key bex.imdb api-key
+
+# List all keys for a plugin
+bex list-keys bex.imdb
+```
+
+### C++ CLI
+
+```bash
+# Set an API key
+./bexcli set-key bex.imdb api-key "your-api-key-here"
+
+# Get an API key value
+./bexcli get-key bex.imdb api-key
+
+# Delete an API key
+./bexcli delete-key bex.imdb api-key
+
+# List all keys for a plugin
+./bexcli list-keys bex.imdb
+```
+
+### C API
+
+```c
+// Store a secret
+bex_engine_secret_set(engine, "bex.imdb", "api-key", "your-key");
+
+// Retrieve a secret
+char buf[4096];
+size_t buf_len = sizeof(buf);
+bex_engine_secret_get(engine, "bex.imdb", "api-key", buf, &buf_len);
+
+// Delete a secret
+bex_engine_secret_delete(engine, "bex.imdb", "api-key");
+
+// List all secret key names (comma-separated, caller frees with bex_string_free)
+char* keys = bex_engine_secret_keys(engine, "bex.imdb");
+bex_string_free(keys);
+```
+
+### Plugin Access (WIT)
+
+Inside a plugin, secrets are accessed read-only through the `secrets` host interface:
+
+```rust
+use bindings::bex::plugin::secrets;
+
+fn get_api_key() -> Option<String> {
+    secrets::get("api-key")
+}
+```
+
+Secrets that a plugin expects are declared in the manifest:
+
+```yaml
+secrets:
+  - api-key
+  - tmdb-token
+```
+
+## Self-Describing IDs
+
+Self-describing IDs are the core design pattern for how the BEX engine handles typed identifiers. The engine itself treats all IDs as opaque strings — it does not parse, validate, or interpret them. Only the plugin knows what its IDs mean and how to decode them.
+
+This means:
+
+- **`get_servers` takes a single `id` parameter** — there is no separate `episode_id` parameter
+- **The engine never parses IDs** — it passes them straight through to the plugin
+- **Each plugin defines its own ID encoding** — different plugins can use entirely different schemes
+- **IDs are portable** — they can be stored, serialized, and passed between systems without the engine needing to understand them
+
+### Example: GogoAnime Episode IDs
+
+The GogoAnime plugin encodes episode context directly in the ID:
+
+```
+{slug}$ep={episode_number}$sub={0|1}$dub={0|1}
+```
+
+| ID | Meaning |
+|----|---------|
+| `one-piece$ep=1$sub=1$dub=0` | One Piece episode 1, subbed |
+| `jujutsu-kaisen-tv$ep=24$sub=0$dub=1` | Jujutsu Kaisen episode 24, dubbed |
+
+When `get_servers` is called with this ID, the GogoAnime plugin splits on `$` and parses each key-value pair to determine the slug, episode number, and sub/dub flags. The engine never does this parsing — it just passes the string through.
+
+### Example: IMDb Media IDs
+
+The IMDb plugin might use a different scheme entirely (e.g., `tt1234567`), and the engine works equally well because it does not interpret the ID.
+
+### Usage
+
+```bash
+# The ID is self-describing — pass it directly
+bex servers bex.gogoanime 'one-piece$ep=1$sub=1$dub=0'
+
+# C++ CLI works the same way
+./bexcli servers bex.gogoanime 'one-piece$ep=1$sub=1$dub=0'
+```
+
+## WIT Interface Definitions
+
+### Host-Provided APIs (imports — plugins call these)
+
+| Interface | Functions | Description |
+|-----------|-----------|-------------|
+| `http` | `send-request` | HTTP client with caching, redirect control, size limits |
+| `kv` | `set`, `get`, `remove`, `keys` | Scoped key-value storage |
+| `secrets` | `get` | Read-only secret/API key access |
+| `log` | `write` | Structured logging through host |
+| `clock` | `now-ms`, `monotonic` | Time access |
+| `rng` | `bytes` | Secure random bytes |
+| `js` | `eval-js`, `eval-js-opts`, `call-js-fn`, `clear-js-fn` | QuickJS sandbox — safe JS eval, function call, and cleanup |
+
+### Plugin-Provided APIs (exports — host calls these)
+

+
+## Writing a Plugin
+
+### 1. Create a plugin project
+
+```bash
+cargo init --lib my-plugin
+cd my-plugin
+```
+
+Add to `Cargo.toml`:
+
+```toml
+[package]
+name = "my-plugin"
+version = "0.1.0"
+edition = "2021"
+
+[dependencies]
+wit-bindgen = { version = "0.57.1", features = ["bitflags"] }
+serde = { version = "1", features = ["derive"] }
+serde_json = "1"
+
+[lib]
+crate-type = ["cdylib"]
+
+[package.metadata.component]
+package = "bex:my-plugin"
+
+[package.metadata.component.dependencies]
+```
+
+### 2. Copy the WIT definitions
+
+Copy `wit/plugin.wit` from the engine repository into your plugin's `wit/` directory.
+
+### 3. Generate bindings
+
+Run `cargo build --target wasm32-wasip1 --release` once to generate `src/bindings.rs`, then implement the `Guest` trait:
+
+```rust
+#[allow(warnings)]
+mod bindings;
+
+use bindings::bex::plugin::common::*;
+use bindings::bex::plugin::http;
+use bindings::exports::api::Guest;
+
+struct Component;
+
+impl Guest for Component {
+    fn get_home(_ctx: RequestContext) -> Result<Vec<HomeSection>, PluginError> {
+        Ok(vec![HomeSection {
+            id: "home".to_string(),
+            title: "My Plugin".to_string(),
+            subtitle: None,
+            items: vec![],
+            next_page: None,
+            layout: CardLayout::Grid,
+            show_rank: false,
+            categories: vec![],
+            extra: vec![],
+        }])
+    }
+
+    fn search(_ctx: RequestContext, query: String, _filters: SearchFilters) -> Result<PagedResult, PluginError> {
+        let response = http::send_request(&http::Request {
+            method: http::Method::Get,
+            url: format!("https://api.example.com/search?q={}", query),
+            headers: vec![],
+            body: None,
+            timeout_ms: Some(10000),
+            follow_redirects: true,
+            cache_mode: http::CacheMode::Normal,
+            max_bytes: Some(1024 * 1024),
+        }).map_err(|e| PluginError::Network(format!("{:?}", e)))?;
+
+        Ok(PagedResult { items: vec![], categories: vec![], next_page: None })
+    }
+
+    fn get_servers(_ctx: RequestContext, id: String) -> Result<Vec<Server>, PluginError> {
+        // The ID is self-describing — parse it however your plugin needs
+        // The engine does not interpret the ID, only your plugin does
+        let parts: Vec<&str> = id.split('$').collect();
+        // ... parse and fetch servers ...
+        Ok(vec![])
+    }
+
+    // ... implement other methods ...
+}
+
+bindings::export!(Component with_types_in bindings);
+```
+
+### 4. Build, convert, and pack
+
+```bash
+# Step 1: Compile to WASM
+cargo build --target wasm32-wasip1 --release
+
+# Step 2: Convert to a WASM Component
+wasm-tools component new \
+    target/wasm32-wasip1/release/my_plugin.wasm \
+    -o target/components/my-plugin.component.wasm \
+    --adapt /path/to/wasi_snapshot_preview1.reactor.wasm
+
+# Step 3: Pack into a .bex package
+bex pack manifest.yaml target/components/my-plugin.component.wasm my-plugin.bex
+
+# Step 4: Install
+bex install my-plugin.bex
+```
+
+### Plugin Manifest
+
+```yaml

+
+## CMake Integration
+
+The C++ CLI's `CMakeLists.txt` is designed to be self-contained and reusable. You can integrate the BEX engine into any C++ project with minimal setup. The only requirement is the `bex_engine.h` header and the Rust static/shared library — no cxx bridge, no code generation, no special include paths.
+
+### Quick Integration
+
+1. Build the Rust library:
+
+```bash
+cargo build -p bex-runtime --release
+```
+
+2. Copy the `cpp-cli/` directory into your project (or reference it via `BEX_ENGINE_ROOT`).
+
+3. In your `CMakeLists.txt`:
+
+```cmake
+cmake_minimum_required(VERSION 3.16)
+project(myapp LANGUAGES C CXX)
+
+set(CMAKE_CXX_STANDARD 17)
+
+# Point to the bex-engine root (required if not inside the repo)
+set(BEX_ENGINE_ROOT "/path/to/bex-engine")
+
+# Add the bex engine subdirectory
+add_subdirectory(${BEX_ENGINE_ROOT}/cpp-cli bex_engine_build)
+
+# Link against the imported bex::engine target
+add_executable(myapp main.cpp)
+target_link_libraries(myapp PRIVATE bex::engine)
+```
+
+### BEX_ENGINE_ROOT Variable
+
+The CMake build uses `BEX_ENGINE_ROOT` to locate the Rust library and the C header:
+
+- **Default**: If not set, it walks up from `CMAKE_SOURCE_DIR` to find a directory containing `Cargo.toml`
+- **Override**: Set `-DBEX_ENGINE_ROOT=/path/to/bex-engine` when running cmake
+
+### Imported Target
+
+The CMakeLists.txt creates an INTERFACE library target `bex::engine` with all include paths and link libraries configured:
+
+```cmake
+target_link_libraries(myapp PRIVATE bex::engine)
+```
+
+### Helper Target
+
+A `rustlib` custom target is provided to build the Rust library from CMake:
+
+```bash
+make rustlib
+```
+
+### Required Files
+
+| File | Purpose |
+|------|---------|
+| `cpp-cli/bex_engine.h` | Pure C ABI header (the FFI boundary) |
+| `target/release/libbex_runtime.a` | Rust static library (Pure C ABI exports) |
+
+That's it. No generated headers, no bridge codegen, no extra include paths.
+
+## Error Code Reference
+
+| Code | Meaning |
+|------|---------|
+| `ABI_MISMATCH` | Plugin ABI version incompatible |
+| `INVALID_MANIFEST` | Manifest validation failed |
+| `HASH_MISMATCH` | Package integrity check failed |

+/// @file bex_engine.h
+/// @brief Pure C ABI for the Bex WASM Plugin Engine (v4).
+///
+/// This header defines the boundary between the Rust engine and any C/C++ consumer.
+/// Rust implements these functions via `extern "C"`. C++ consumes them directly.
+/// No bridge crate, no code generation — just link against libbex_runtime.
+///
+/// Architecture:
+///   - All async operations return a request_id immediately.
+///   - When the operation completes, Rust invokes the BexResultCallback from a
+///     background Tokio thread.
+///   - C++ must copy/parse the payload before the callback returns (payload is
+///     owned by Rust and freed after the callback returns).
+///   - Sync operations (install, uninstall, list, secrets) block until done.
+///
+/// Thread safety:
+///   - bex_engine_new / bex_engine_free are NOT thread-safe.
+///   - All bex_submit_* functions are thread-safe (internally synchronized).
+///   - The callback is invoked from a Rust/Tokio background thread — the
+///     callback implementation must be thread-safe.

+//
+// Full-featured CLI demonstrating the pure C FFI with async callback pattern.
+// No bridge crate dependency — just bex_engine.h and the Rust static/shared library.
+//
+// Features:
+//   - Plugin management: install, uninstall, list, info, enable, disable
+//   - API key management: set-key, get-key, delete-key, list-keys
+//   - Media browsing: home, search, info, servers, stream
+//   - Async operations use std::promise/future for blocking wait
+//
+// Build with CMake:

+//! 1. C++ calls `bex_submit_search(engine, plugin_id, query, callback, user_data)`

+//! 3. On completion, Rust invokes `callback(user_data, request_id, success, payload, len)`

+//! 4. C++ receives the result and can parse/copy it before the callback returns
+//!
+//! There is NO event queue, NO polling, NO cxx dependency.

+//! The BexRuntime — async callback-driven wrapper around bex_core::Engine.
+//!
+//! BexRuntime adds these capabilities on top of the sync bex_core::Engine:
+//!
+//! 1. **Callback-based async**: Plugin call results are delivered directly
+//!    to a C function pointer callback from a background Tokio thread.
+//!    No event queue, no polling.
+//!
+//! 2. **Lane-based scheduling**: Plugin calls are dispatched to tokio tasks
+//!    with concurrency limits per priority lane (Control, User, Background).
+//!
+//! 3. **Cancellation**: Each request gets a `CancellationToken`. The C++
+//!    backend can cancel via `bex_cancel_request()`.

+//!
+//! - **Control** (1 permit): Serialized operations like install/uninstall.
+//!   Only one control operation at a time to avoid race conditions.
+//!
+//! - **User** (4 permits): Interactive operations like search, get_info,
+//!   get_servers. These are user-facing and should be responsive.
+//!
+//! - **Background** (2 permits): Low-priority operations like prefetching,
+//!   article fetching. Limited to avoid starving user-facing calls.
+//!
+//! Additional global limits:
+//! - **WASM** (4 permits): Max concurrent WASM instantiations.
+//!   Each instantiation uses memory and CPU for compilation.
+//! - **HTTP** (8 permits): Max concurrent HTTP requests across all plugins.
+//!   Prevents connection pool exhaustion.
