 ## OVERVIEW
 
-VS Code extension that colors JSX component tags based on `"use client"` directive detection — visually distinguishing React Server Components from Client Components in Next.js App Router projects.
+Multi-package Rust + TypeScript monorepo that colors JSX component tags based on `"use client"` directive detection, visually distinguishing React Server Components from Client Components in Next.js App Router projects.
+
+The single analysis implementation lives in `packages/core` (Rust, oxc-based). All editor integrations consume that core: VS Code loads it as WebAssembly, Zed runs it through a native LSP binary.

 ## CONVENTIONS
 
-- **Linter**: oxlint (not ESLint) — run `bun run lint:fix`
-- **Package manager**: bun (but npm-compatible)
-- **Test runner**: Node.js built-in `node:test` — run `bun run test`
-- **Build**: `bun build` bundles `src/extension.ts` → single `out/extension.js` (CJS, externals: vscode + typescript)
-- **Type check**: `tsc` with `noEmit` — run `bun run typecheck`
-- **Publish**: `@vscode/vsce` — manual `vsce publish` (prepublish runs minified production build)
-- **Pre-commit hook**: Husky runs lint automatically
-- **TypeScript**: Strict mode with `noUnusedLocals` + `noUnusedParameters`
-- **Import style**: `node:` prefix for Node builtins, type-only imports where possible
+- **Package manager**: bun (workspace root) + Cargo (Rust workspace)
+- **Rust edition**: 2024, `rust-version = "1.93"` (workspace default; all crates inherit via `.workspace = true`)
+- **Linter (JS)**: oxlint — run `bun run lint:js` or `bun run lint:fix`
+- **Linter (Rust)**: `cargo fmt` + `cargo clippy` — run `bun run lint:rust` or `bun run lint:fix`
+- **Test runner**: `bun run test` runs `cargo test` (Rust) + VS Code integration tests
+- **Build**: `bun run build` delegates to each package's own build script
+- **Type check**: `bun run typecheck` delegates to each package's `tsc`
+- **Publish (VS Code)**: `@vscode/vsce` — manual `vsce package` / `vsce publish` (prepublish runs `build:production`)

+- **Import style**: `node:` prefix for Node builtins
 
 ## ANTI-PATTERNS (THIS PROJECT)
 
-- **No error throwing** — All functions return `undefined`/`[]`/`'unknown'` on failure. Never throw.
-- **No logging** — No console.log/debug/warn anywhere. Only `vscode.window.showInformationMessage` for user-facing feedback.
-- **No `any` types** — Full strict TypeScript; uses `satisfies` for type narrowing.
-- **Don't edit `out/`** — Generated directory; always edit `src/` and rebuild.
+- **No error throwing** — All Rust functions return `Option`/`Result` and callers degrade gracefully. TS functions return `undefined`/`[]` on failure. Never throw or panic in normal paths.
+- **No logging** — No `console.log`/`eprintln!`/`dbg!` anywhere. Only `vscode.window.showInformationMessage` for user-facing VS Code feedback.
+- **No `any` types** — Full strict TypeScript. Uses `satisfies` for type narrowing.
+- **No `unsafe` except documented WASM** — `packages/core-wasm/src/host.rs` contains one documented `unsafe impl Send/Sync` for `JsHost` with a SAFETY comment explaining the single-threaded wasm32 context. All other crates have `unsafe_code = "warn"` from the workspace lint config.
+- **Don't edit `out/` or generated WASM** — `packages/vscode/out/` and the wasm-pack output under `packages/core-wasm/pkg/` are generated. Always edit `src/` and rebuild.
+- **Don't edit `conformance/fixtures/`** — Fixture files are the test inputs. Regenerate goldens with `emit-canonical`, never hand-edit them.
+- **Graceful degradation** — Unresolvable imports are skipped silently. The extension shows fewer decorations rather than crashing.
 
 ## UNIQUE STYLES
 
-- **Signature-based caching**: Files tracked by `"disk:{mtime}:{size}"` or `"open:{version}"` tokens. When adding new caches, follow this pattern.
-- **Graceful degradation**: Extension silently shows fewer decorations rather than crashing. Unresolvable imports are skipped, not errored.
-- **Tag-only coloring**: Only `<Component`, `>`, `/>`, `</Component>` get colored — props are left untouched. Ranges are explicit `{start, end}` byte offsets.
-- **`SourceHost` abstraction**: All file I/O goes through this interface. Production uses `WorkspaceSourceHost` (extension.ts:192); tests use an in-memory mock.
+- **Single Rust core, multiple consumers**: All analysis logic lives in `packages/core`. The WASM wrapper and LSP server are thin adapters. Never duplicate analysis logic in the TS layer.
+- **Conformance goldens**: `conformance/goldens/**/*.json` are static byte-equal snapshots. `packages/core/tests/conformance.rs` fails if output drifts. To add a case: add a fixture, run `emit-canonical`, commit the golden.
+- **Tag-only coloring (VS Code)**: Only `<Component`, `>`, `/>`, `</Component>` get colored — props are left untouched. Ranges are explicit `{start, end}` byte offsets from the Rust core.
+- **Signature-based caching (VS Code)**: Files tracked by `"disk:{mtime}:{size}"` or `"open:{version}"` tokens. Follow this pattern when adding new caches.
 - **Component detection**: Only capitalized identifiers (`/^[A-Z]/`) are treated as components (React convention). Recognizes `forwardRef`, `memo`, `React.forwardRef`, `React.memo` wrappers.
+- **External contracts frozen**: VS Code marketplace id `devfive.react-component-lens`, npm package `@react-component-lens/core-wasm`, binaries `rcl-lsp` and `emit-canonical`, Zed extension id. Do not rename these.

+
+Full `test:coverage` command (verbatim from root `package.json`):
+```
+cargo tarpaulin --engine llvm --workspace --exclude rcl-zed --exclude rcl-core-wasm --exclude-files "**/main.rs" --exclude-files "**/src/bin/**" --exclude-files "**/tests/**" --exclude-files "packages/core-wasm/**" --out Stdout --fail-under 100
 ```
 
 ## NOTES
 
-- **Runtime dependency on TypeScript**: `typescript` is listed under `dependencies` (not devDependencies) because the extension uses `ts.createSourceFile()` and `ts.resolveModuleName()` at runtime for AST parsing.
-- **VS Code engine >=1.110.0**: Uses `DecorationRangeBehavior.ClosedClosed` and other modern APIs.
-- **Test helper `createProject()`**: Creates real temp directories with files, returns a `SourceHost` mock. Uses `Symbol.dispose()` for cleanup — always wrap in try/finally.
-- **No CI/CD**: Quality enforcement is local-only (husky pre-commit). No GitHub Actions or automated publishing.
+- **Runtime analysis is pure Rust**: The TypeScript layer in `packages/vscode` is a thin orchestration wrapper. It does not parse JSX or resolve imports itself; all that logic runs inside the WASM binary.
+- **WASM build requires wasm-pack**: `packages/core-wasm` is built with `wasm-pack --target nodejs`. The output (`core_wasm.js` + `core_wasm_bg.wasm`) is copied into `packages/vscode/out/` by the `copy:wasm` script.
+- **Zed extension is wasm32-wasip1**: `packages/zed` compiles to a WASM component (cdylib). It does not link `rcl-core` directly; it downloads and runs the `rcl-lsp` binary at runtime. The `test:wasm` script verifies it compiles.
+- **LSP binary distribution**: The Zed extension downloads a platform-specific `rcl-lsp` binary from the matching GitHub Release. During local development, placing `rcl-lsp` on `PATH` bypasses the download.
+- **Coverage gate is 100%**: `test:coverage` uses `cargo tarpaulin` with `--fail-under 100`. Excluded: `main.rs`, `src/bin/`, test files themselves, and the WASM crates.
+- **CI/CD**: `.github/workflows/deploy.yml` builds per-platform `rcl-lsp` binaries and publishes releases. Local enforcement via husky pre-commit (`bun run lint`).
+- **VS Code engine**: `^1.14.0` (from `packages/vscode/package.json`).

-# React Component Lens
+# React Component Lens — Monorepo
 
-Visually distinguish Server Components and Client Components in React / Next.js projects directly in your editor.
+Visually distinguish React Server Components and Client Components directly in your editor.
 
-[![Visual Studio Marketplace](https://img.shields.io/visual-studio-marketplace/v/devfive.react-component-lens)](https://marketplace.visualstudio.com/items?itemName=devfive.react-component-lens)
+This repository is a [bun workspace](https://bun.sh/docs/install/workspaces) plus Cargo workspace monorepo that hosts the shared Rust analysis core and editor integrations for multiple platforms.
 
-![React Component Lens demo](medias/demo.png)
+## Architecture
 
-## Why
+React Component Lens has one analysis implementation: [`packages/core`](packages/core). That Rust core parses JSX/TSX, resolves imports, detects `"use client"`, and is validated against the static fixtures and goldens in [`conformance/`](conformance).
 
-In Next.js App Router and React Server Components, the boundary between server and client execution is critical for performance and bundle size. But JSX like `<MyComponent />` gives no visual cue about where it runs.
+Consumers use the same core through platform-specific wrappers:
 
-React Component Lens solves this by coloring component tags based on whether the imported file contains `"use client"`.
+- VS Code loads [`packages/core-wasm`](packages/core-wasm), built with `wasm-pack --target nodejs`, and bundles `core_wasm.js` plus `core_wasm_bg.wasm` into the extension.
+- Zed uses the native [`rcl-lsp`](packages/lsp) binary from the Cargo workspace.
 
-## How It Works
+## Packages
 
-1. Parses the active `.tsx` / `.jsx` file for JSX tags
-2. Resolves each import to its source file (supports relative paths, `tsconfig` path aliases, and barrel re-exports)
-3. Detects `"use client"` at the top of the resolved file
-4. Colors the tag shell (`<Component`, `>`, `/>`, `</Component>`) — props are left untouched
-
-Components without `"use client"` are treated as Server Components.
-
-## Settings
-
-| Setting | Default | Description |
+| Package | Path | Description |
 |---|---|---|
-| `reactComponentLens.enabled` | `true` | Enable or disable decorations |
-| `reactComponentLens.debounceMs` | `200` | Delay before recomputing after changes (0 – 2000 ms) |
-| `reactComponentLens.scope.element` | `true` | Highlight JSX element tags (`<Component />`, `</Component>`) |
-| `reactComponentLens.scope.declaration` | `true` | Highlight component declaration names (function, class, variable) |
-| `reactComponentLens.scope.export` | `true` | Highlight component names in export declarations |
-| `reactComponentLens.scope.import` | `true` | Highlight component names in import declarations |
-| `reactComponentLens.scope.type` | `true` | Highlight TypeScript interface and type alias declaration names |
-| `reactComponentLens.highlightColors.clientComponent` | `#14b8a6` | Text color for Client Component tags |
-| `reactComponentLens.highlightColors.serverComponent` | `#f59e0b` | Text color for Server Component tags |
-
-Colors can be any valid CSS color string. The VS Code Settings UI shows a color picker for these fields.
-
-## Commands
-
-| Command | Description |
-|---|---|
-| `React Component Lens: Refresh Decorations` | Clear caches and reapply decorations |
-
-## Requirements
-
-- VS Code 1.14.0 or later
-- A project with `.tsx` or `.jsx` files
-
-No additional runtime, build step, or Next.js installation is required.
+| Rust core | [`packages/core`](packages/core) | Single source of truth for component analysis. |
+| WASM wrapper | [`packages/core-wasm`](packages/core-wasm) | Node-targeted WASM package consumed by VS Code. |
+| LSP server | [`packages/lsp`](packages/lsp) | Native `rcl-lsp` analysis server for editor clients. |
+| Zed extension | [`packages/zed`](packages/zed) | Zed integration that runs the native LSP server. |
+| VS Code extension | [`packages/vscode`](packages/vscode) | The VS Code / Open VSX extension (`devfive.react-component-lens`). |
+
+## Development
+
+```bash
+bun install            # install all workspace dependencies
+bun run build          # build every package
+bun run typecheck      # type-check every package
+bun run lint           # lint the whole workspace
+bun run test           # run the test suite
+bun run test:coverage  # run Rust coverage with a 100% gate
+```
+
+To work on a single package, use bun's filter flag:
+
+```bash
+bun run --filter react-component-lens build
+```

+# Conformance Contract (FROZEN)
+
+**contractVersion:** 1
+**Status:** Frozen. Changes require a reviewed PR that bumps `contractVersion` and regenerates all goldens.
+
+This document defines the **canonical, normalized output** that the TypeScript oracle (legacy `packages/core`) and the Rust engine (`packages/core`) MUST produce **identically** for the same input. Parity is asserted by byte-equality of the serialized canonical JSON (analyzer) and of the resolution trace (resolver).
+
+---
+
+## 1. Oracle pinning (recorded in every golden header)
+
+Goldens are generated by the TypeScript implementation, which is the **specification**.
+
+```jsonc
+{
+  "contractVersion": 1,
+  "tsVersion": "5.9.3",      // typescript package version used to generate goldens
+  "generatorVersion": "1",    // golden-generator schema version
+  "platform": "neutral"       // outputs MUST be platform-independent (see §4)
+}
+```
+
+- `typescript` is pinned to **5.9.3** and treated as **vendored spec**. It is NOT upgraded as routine maintenance. Upgrading it (e.g. to 6.x) is a deliberate, reviewed change that regenerates goldens.
+- Regenerating goldens requires an explicit review gate (PR checklist).
+
+---
+
+## 2. Position unit: **UTF-16 code units** (NON-NEGOTIABLE)
+
+- All `start`/`end` offsets are **UTF-16 code-unit indices** into the source text — the native unit of the TypeScript compiler API (`node.getStart(sourceFile)` / `node.end`) and of the LSP default position encoding.
+- **Rust side:** `oxc` spans are UTF-8 **byte** offsets. At the AST→model boundary, EVERY offset MUST be converted UTF-8 byte → UTF-16 code unit. ALL downstream Rust logic (including range-contains checks used by kind inference) operates in UTF-16 units, mirroring the TS code 1:1. Conversion is NOT deferred to serialization.
+- `end` is **exclusive** (half-open `[start, end)`), matching TS `node.end`.
+- **Mandatory property test (both engines):** for every emitted range `r`, the UTF-16 substring `source.slice16(r.start, r.end)` MUST equal the expected literal substring for that fixture.
+- Mandatory encoding fixtures: ASCII, emoji (surrogate pairs), CJK, combining marks, BOM, CRLF, and mixtures — placed in identifiers (where legal), JSX text, string literals, and comments preceding the directive.
+
+---
+
+## 3. Canonical analyzer output schema
+
+The analyzer output is `ComponentUsage[]`. Canonical serialization:
+
+```jsonc
+// Array of usages, each:
+{
+  "kind": "client" | "server",          // never "unknown" (internal only)
+  "tagName": "<canonical tag name>",     // §3.1
+  "sourceFilePath": "<canonical path>",  // §4 ; always present in analyzer output
+  "ranges": [ { "start": <u32>, "end": <u32> }, ... ]  // §3.2
+}
+```
+
+### 3.1 `tagName` canonical form
+- Reconstructed from the AST, **trivia-stripped**, never a raw source slice that could contain comments/whitespace.
+- Member-expression tag names join identifier segments with `.` (e.g. `Foo.Bar.Baz`). Lookup name (root identifier) is an analyzer-internal detail and is NOT serialized.
+- Only capitalized identifiers (first char `A`–`Z`, code 65–90) are components; lowercase tags are never emitted.
+
+### 3.2 `ranges`
+- A usage may have multiple disjoint segments (e.g. opening tag shell `<Comp` + delimiter `>` or `/>`).
+- Each segment satisfies `start < end`.
+- Segments within a usage are sorted ascending by `(start, end)`.
+
+### 3.3 Determinism: dedup + total order
+- **Dedup:** remove usages that are structurally identical on the full tuple `(kind, tagName, sourceFilePath, ranges)`.
+- **Total order** over usages (independent of internal production order), compared field-by-field until a difference is found:
+  1. `ranges[0].start` (ascending)
+  2. `ranges[0].end` (ascending)
+  3. `kind` (`client` < `server`, lexicographic)
+  4. `tagName` (lexicographic, UTF-16 code-unit order)
+  5. `sourceFilePath` (lexicographic, UTF-16 code-unit order)
+  6. remaining `ranges` compared pairwise by `(start, end)`, then by length.
+- This order MUST yield a strict total order (the dedup guarantees no fully-equal entries).
+
+---
+
+### 3.4 Serialization
+- Canonical bytes = **compact JSON** (no insignificant whitespace) with object fields in fixed order `kind`, `tagName`, `sourceFilePath`, `ranges`; each range object `start`, `end`. Non-ASCII emitted as raw UTF-8 (not `\u`-escaped); `/` not escaped. Numbers are integers (no decimal point/exponent). This is what both engines must emit byte-identically.
+
+## 4. Canonical path identity (`sourceFilePath`)
+
+- Canonical = the TypeScript oracle's resulting absolute path, normalized:
+  - separators → forward slash `/`
+  - on Windows, drive letter lowercased (`C:/…` → `c:/…`)
+- **Symlink behavior = match TS default.** TS resolves through the filesystem; the Rust resolver MUST reproduce TS's result (realpath behavior included). Verified via the resolver trace (§6), not assumed.
+- In analyzer output `sourceFilePath` is always present (local usages use the analyzed file path; imported usages use the resolved path). Unresolved imports emit **no usage** (the TS analyzer skips them), so `null` does not appear in analyzer output. `null` is reserved for resolver-trace records where resolution fails.
+
+---
+
+## 5. Directive detection spec (`"use client"`) — reimplement verbatim
+
+Mirror `hasUseClientDirective` EXACTLY (do NOT use `oxc` `program.directives`, whose AST-directive semantics differ). Scan the raw source from offset 0:
+
+1. **Skip** any char with code `<= 32` (whitespace/control), or `;` (59), or BOM (`0xFEFF`).
+2. **Line comment:** `//` → skip to next `\n` (code 10), continue.
+3. **Block comment:** `/*` → skip until `*/`, continue.
+4. **String literal** (`"` code 34 or `'` code 39):
+   - Client iff the following bytes are EXACTLY `use client` (codes: `u`117 `s`115 `e`101 `space`32 `c`99 `l`108 `i`105 `e`101 `n`110 `t`116) at offsets `+1..+10` AND the char at `+11` equals the opening quote. Raw-byte match — escapes are NOT interpreted (`"use\u0020client"` does NOT match).
+   - If it matches → file is **client**.
+   - Otherwise → skip past this string's closing quote and **continue** (this permits a preceding directive run, e.g. `"use strict"; "use client";`).
+5. **Any other character** → stop; file is **not client** (i.e. **server**).
+6. End of input reached → **not client** (server).
+
+A file is `client` iff this scan returns client; otherwise `server`. `"use server"` inside function bodies and the other kind-inference heuristics are separate (analyzer logic), not part of this file-level directive check.
+
+---
+
+## 6. Resolver trace (parity unit for the resolver)
+
+The resolver is conformed separately. For each `(fromFilePath, specifier)` the engines emit a trace record; parity requires **trace-equality** (or a narrowly whitelisted, reviewed carve-out proven not to change which file is inspected for the directive).
+
+```jsonc
+{
+  "fromFilePath": "<canonical>",
+  "specifier": "<string>",
+  "configPath": "<canonical>|null",        // nearest tsconfig/jsconfig chosen
+  "candidatesTried": ["<canonical>", ...],   // in order
+  "resolved": "<canonical>|null",            // final accepted file (after .d.ts rejection)
+  "rejectedReason": "unresolved|dts|unsupported-ext|null"
+}
+```
+
+- Accepted files end in `.ts`/`.tsx`/`.js`/`.jsx` and are NOT `.d.ts` (post-filter mirrors the TS wrapper).
+- Default compiler options when no config: `{ allowJs:true, jsx:preserve, module:ESNext, moduleResolution:Bundler, target:ES2022 }`.
+- Config discovery walks up from the importing file's directory looking for `tsconfig.json` then `jsconfig.json`.
+
+---
+
+## 7. What this contract does NOT cover
+- LSP position encoding (byte/UTF-16 → `{line, character}`) — a separate layer (`packages/lsp`) with its own tests.
+- Caching/signature behavior — disabled or trace-asserted during conformance/fuzzing to avoid nondeterminism.
+- Performance — measured separately after correctness is proven.

+# React Component Lens
+
+Visually distinguish Server Components and Client Components in React / Next.js projects directly in your editor.
+
+[![Visual Studio Marketplace](https://img.shields.io/visual-studio-marketplace/v/devfive.react-component-lens)](https://marketplace.visualstudio.com/items?itemName=devfive.react-component-lens)
+
+![React Component Lens demo](medias/demo.png)
+
+## Why
+
+In Next.js App Router and React Server Components, the boundary between server and client execution is critical for performance and bundle size. But JSX like `<MyComponent />` gives no visual cue about where it runs.
+
+React Component Lens solves this by coloring component tags based on whether the imported file contains `"use client"`.
+
+## Architecture
+
+The extension uses the shared Rust analysis core from the React Component Lens workspace. [`packages/core`](../core) is the single implementation; [`packages/core-wasm`](../core-wasm) builds it with `wasm-pack --target nodejs` so VS Code can load the same analyzer as WebAssembly. Zed consumes the same core natively through the `rcl-lsp` binary.
+
+## How It Works
+
+1. Loads the bundled Rust WASM core (`core_wasm.js` and `core_wasm_bg.wasm`)
+2. Parses the active `.tsx` / `.jsx` file for JSX tags
+3. Resolves each import to its source file (supports relative paths, `tsconfig` path aliases, and barrel re-exports)
+4. Detects `"use client"` at the top of the resolved file
+5. Colors the tag shell (`<Component`, `>`, `/>`, `</Component>`) — props are left untouched
+
+Components without `"use client"` are treated as Server Components.
+
+## Settings
+
+| Setting | Default | Description |
+|---|---|---|
+| `reactComponentLens.enabled` | `true` | Enable or disable decorations |
+| `reactComponentLens.debounceMs` | `200` | Delay before recomputing after changes (0 – 2000 ms) |
+| `reactComponentLens.scope.element` | `true` | Highlight JSX element tags (`<Component />`, `</Component>`) |
+| `reactComponentLens.scope.declaration` | `true` | Highlight component declaration names (function, class, variable) |
+| `reactComponentLens.scope.export` | `true` | Highlight component names in export declarations |
+| `reactComponentLens.scope.import` | `true` | Highlight component names in import declarations |
+| `reactComponentLens.scope.type` | `true` | Highlight TypeScript interface and type alias declaration names |
+| `reactComponentLens.highlightColors.clientComponent` | `#14b8a6` | Text color for Client Component tags |
+| `reactComponentLens.highlightColors.serverComponent` | `#f59e0b` | Text color for Server Component tags |
+
+Colors can be any valid CSS color string. The VS Code Settings UI shows a color picker for these fields.
+
+## Commands
+
+| Command | Description |
+|---|---|
+| `React Component Lens: Refresh Decorations` | Clear caches and reapply decorations |
+
+## Requirements
+
+- VS Code 1.14.0 or later
+- A project with `.tsx` or `.jsx` files
+
+No additional runtime, build step, or Next.js installation is required.

+# React Component Lens — Zed Extension
+
+Colors JSX component tags in `.tsx` files based on the `"use client"` directive:
+
+- **🩵 Teal** — Client Component (`'use client'` reachable through imports)
+- **🟠 Orange** — Server Component (default in App Router)
+
+Mirrors the [VS Code extension](https://marketplace.visualstudio.com/items?itemName=devfive.react-component-lens) of the same name.
+
+## How it works
+
+The extension ships a Rust LSP server (`rcl-lsp`, built from `packages/lsp`) that emits two custom semantic token types:
+
+- `rscClientComponent`
+- `rscServerComponent`
+
+`rcl-lsp` attaches to Zed's built-in **TSX** language and layers its tokens on
+top of `vtsls` — we do not redefine the language, so all normal TypeScript
+highlighting and tooling is preserved.
+
+The first time you open a `.tsx` file the extension downloads a platform-specific `rcl-lsp` binary from the matching GitHub Release of `dev-five-git/react-component-lens`. Subsequent loads use the cached binary.
+
+## Configuration (required for colors)
+
+Zed only renders semantic tokens when they are enabled, and it needs a rule
+mapping our custom token types to colors. Add both to your Zed
+`settings.json`:
+
+```json
+{
+  // 1. Enable LSP semantic tokens on top of tree-sitter highlighting.
+  "semantic_tokens": "combined",
+
+  // 2. Map our custom RSC token types to colors (applies to every language,
+  //    including the built-in TSX that rcl-lsp attaches to).
+  "global_lsp_settings": {
+    "semantic_token_rules": [
+      { "token_type": "rscClientComponent", "foreground_color": "#22d3ee" },
+      { "token_type": "rscServerComponent", "foreground_color": "#f97316" }
+    ]
+  }
+}
+```
+
+> Why settings instead of a bundled rule file? Zed only loads an extension's
+> `semantic_token_rules.json` when it sits next to a `config.toml` that
+> *defines* a language. Defining a language named `TSX` would shadow Zed's
+> built-in TSX (breaking syntax highlighting), so the colors are configured in
+> user settings instead.
+
+## Building locally
+
+Build the WASM extension and the language server, then make the server
+discoverable on `PATH` so the dev extension uses your local build instead of
+downloading a release:
+
+```bash
+# 1. Build the language server and put it on PATH
+cargo build --release -p rcl-lsp --bin rcl-lsp
+#   e.g. add target/release to PATH, or copy rcl-lsp(.exe) into a PATH dir
+
+# 2. Build the Zed extension (WASM)
+cargo build --target wasm32-wasip1 --release -p rcl-zed
+```
+
+Then in Zed: `cmd+shift+p` → "zed: install dev extension" → choose `packages/zed/`.
+
+The extension resolves the `rcl-lsp` binary in this order: cached path → a
+`rcl-lsp` found on `PATH` → prebuilt binary downloaded from the matching GitHub
+Release. The `PATH` lookup is what enables this no-release dev workflow.
