+Welcome to the complete developer handbook for **Slice (Nexus-JS)** (`v0.10.12`) — a microVM-grade JavaScript and TypeScript runtime, compiler, HTTP server, and AI sandbox engineered in Rust.
Whether you are building a high-throughput full-stack web service, packaging a CLI tool into a single zero-dependency executable, running 1,000 untrusted customer plugins on a single machine, or executing LLM-generated TypeScript inside an AI coding agent, this handbook walks you through every feature, CLI command, API, security capability, and migration pattern from the perspective of an application developer.

+## 5. Multi-Tenant Edge KV, AI Agent Checkpoints & 5-Ring Security Telemetry
+
+| Subsystem / Benchmark | Measured Telemetry | Status |
+| :--- | :--- | :---: |
+| **Sharded `Slice.kv` (`1,001` Get/Set/Incr Ops in Isolate)** | **`564.84 us`** total (`--warm`, `8,431 B` memory cage) | `PASS` |
+| **Multi-Tenant `--tenant-dir` Zero-Downtime Hot-Swap** | Live atomic replacement of `tenant-alpha.cas` (`v1 -> v2-hot-swapped`) with isolated `Slice.kv` state | `PASS` |
+| **Deterministic Time-Travel Replay (`--deterministic=20261019`)** | 100% bit-for-bit identical PRNG (`Math.random`) & virtual clock (`Date.now`, `performance.now`) | `PASS` |
+| **Tree-of-Thought AI Agent (`Slice.checkpoint` + 3 `evalSandbox` + `restore`)** | **`74.64 us`** total (`3.50 us` child sandbox) | `PASS` |
+| **Cloud Metadata SSRF (`169.254.169.254`) & Base64 Egress DLP Guard** | `SSRF_METADATA_BLOCKED` & `EGRESS_SECRET_LEAK_BLOCKED` deterministically trapped | `PASS` |
+| **Built-In Model Context Protocol Server (`slice mcp --smoke-test`)** | JSON-RPC 2.0 `initialize`, `tools/list`, `tools/call` verified over `stdio` | `PASS` |
