### PipelineTestServer constructor setup

Source: https://docs.unity3d.com/Packages/com.unity.pipeline%400.8/manual/testing.html

Creates a TestEditorPipelineServer, starts it on a port in 7850-7899, and creates a PipelineClient with a token. Wrap in a using block to stop the server at test end.

```csharp
public PipelineTestServer()
{
    m_Server = new TestEditorPipelineServer();
    m_Server.Start(); // auto-assigns a port in 7850-7899; writes no descriptor
    m_Client = new PipelineClient($"http://127.0.0.1:{m_Server.Port}", SecurityTokenManager.GetOrCreateToken());
}
```

### RuntimePipelineBootstrap.Bootstrap()

Source: https://docs.unity3d.com/Packages/com.unity.pipeline%400.8/api/Unity.Pipeline.RuntimePipelineBootstrap.html

Core bootstrap logic, split out from the attributed entry point so tests can invoke it directly instead of waiting for a real domain/Player boot. Returns the created driver, or null if the server should not start (no config asset, or disabled). Idempotent: a second call returns the existing Instance rather than creating a duplicate.

```APIDOC
## Method: Bootstrap()

### Description
Core bootstrap logic, split out from the attributed entry point so tests can invoke it directly instead of waiting for a real domain/Player boot. Returns the created driver, or null if the server should not start (no config asset, or disabled). Idempotent: a second call returns the existing Instance rather than creating a duplicate.

### Declaration
```csharp
public static RuntimePipelineDriver Bootstrap()
```

### Returns
- **RuntimePipelineDriver** - The created (or already-existing) driver, or null if the server should not start.
```

--------------------------------

### ObjectResolver.Describe

Source: https://docs.unity3d.com/Packages/com.unity.pipeline%400.8/manual/authoring-commands.html

Generates an AuthoringResult for a given object, filling in the appropriate identity fields based on the object kind. Assets get assetPath, guid, fileId, type (+ globalId). Scene/loaded objects get instanceId, hierarchyPath, type (+ globalId).

```APIDOC
## ObjectResolver.Describe

### Description
Generates an AuthoringResult for a given object, filling in the appropriate identity fields based on the object kind. Assets get assetPath, guid, fileId, type (+ globalId). Scene/loaded objects get instanceId, hierarchyPath, type (+ globalId).

### Method
Describe

### Signature
`public static AuthoringResult Describe(Object obj)`

### Parameters
- **obj** (Object) - Required - The object to describe.

### Returns
- **AuthoringResult** - The identity result for the object, or null if the object is not recognized.

### Remarks
- Use this method to return object identity from commands that create or modify objects.
- The returned AuthoringResult is identity only — no success flag, no message. Success/failure and timing live in the outer CommandExecutionResponse.
- To report a failure, throw an exception (ArgumentException for bad input, InvalidOperationException for an operation that failed).
- For a batch, return a model that holds an AuthoringResult[] (see CreateGameObjectsResult).

### Example
```csharp
var result = ObjectResolver.Describe(asset) ?? new AuthoringResult { Type = nameof(Material) };
result.AssetPath = assetPath;   // ensure the path is set even if Describe returned a fresh result
return result;
```
```

--------------------------------

```

--------------------------------

### CodeReloadRegistry.AllowedReloadRoots

Source: https://docs.unity3d.com/Packages/com.unity.pipeline%400.8/api/Unity.Pipeline.CodeReload.CodeReloadRegistry.html

Gets or sets the absolute roots a running Player is allowed to code reload source files from. Baked into RuntimePipelineBuildInfo at build time and published when the runtime server starts.

```APIDOC
## Property: AllowedReloadRoots

### Description
Gets or sets the absolute roots a running Player is allowed to code reload source files from (Assets folder + loaded package locations). Baked into RuntimePipelineBuildInfo at build time and published here when the runtime server starts, so reload commands can validate incoming file paths. Null until published.

### Declaration
```csharp
public static IReadOnlyList<string> AllowedReloadRoots { get; set; }
```

### Property Value
- **IReadOnlyList<string>** - The allowed reload roots.
```

--------------------------------

### Connect to a running Player with the unity CLI

Source: https://docs.unity3d.com/Packages/com.unity.pipeline%400.8/manual/connectivity.html

Use `--runtime` to target a running development Player by process name, or `--runtime-path` to specify the folder or bundle where the runtime port file lives. These options go after `command` and before the command name.

```bash
# By Player process/executable name
unity command --runtime MyGame.exe runtime_status

# By the folder/bundle where the runtime port file lives
unity command --runtime-path "C:\Builds\MyGame" runtime_status             # Windows: next to the .exe
unity command --runtime-path "/Users/me/Builds/MyGame.app" runtime_status  # macOS: the .app bundle
```

--------------------------------

### GET /api/commands?detail=compact&tag=baking&group_by=tag&limit=2 response

Source: https://docs.unity3d.com/Packages/com.unity.pipeline%400.8/manual/connectivity.html

Example response for group_by=tag. Shows a nested groups tree where a node's commands holds only exact-tag commands and count covers the subtree. Pagination happens before grouping.

```json
{
  "groups": [
    {
      "tag": "baking",
      "count": 2,
      "commands": [],
      "children": [

--------------------------------

### CodeReloadRegistry.NoteForFirstReload(string)

Source: https://docs.unity3d.com/Packages/com.unity.pipeline%400.8/api/Unity.Pipeline.CodeReload.CodeReloadRegistry.html

Record a startup fact for the "first reload this session" summary line. Once that line has been printed, a late note (e.g. a player connecting mid-session) is logged directly.

```APIDOC
## Method: NoteForFirstReload(string note)

### Description
Record a startup fact for the "first reload this session" summary line. Once that line has been printed, a late note (e.g. a player connecting mid-session) is logged directly.

### Declaration
```csharp
public static void NoteForFirstReload(string note)
```

### Parameters
- **note** (string) - Short clause, no trailing period, e.g. "3 reloadable method(s) registered".

### Returns
Void.
```

--------------------------------

### Connect to a Unity Editor with the unity CLI

Source: https://docs.unity3d.com/Packages/com.unity.pipeline%400.8/manual/connectivity.html

Run `unity command` with no command name to auto-discover a Unity instance from the current directory and list its available commands. Use `--project-path` to connect to a specific project.

```bash
# Auto-discover a Unity instance from the current directory
unity command

# Connect to a specific project
unity command --project-path /path/to/your/unity/project
```

--------------------------------

### wait_status

Source: https://docs.unity3d.com/Packages/com.unity.pipeline%400.8/manual/commands/wait.html

Get the status/result of an async wait (wait_for with async=true).

```APIDOC
## wait_status

### Description
Get the status/result of an async wait (`wait_for` with `async=true`).

### Parameters

| Parameter | Required | Default | Description |
|-----------|----------|---------|-------------|
| `wait_id` | yes | `–` | The id returned by `wait_for` when `async=true`. |

### Returns
`WaitResult` (`state:"not_found"` if the id is unknown — async waits do not survive a domain reload; completed waits are retained up to a bounded count and pruned oldest-first the next time a `wait_for` is submitted, so a session that never submits another wait keeps its last results queryable).
```

--------------------------------

### run_script

Source: https://docs.unity3d.com/Packages/com.unity.pipeline%400.8/manual/commands/scripts.html

Compile a single project `.cs` file in memory and execute a named static entry point. This is the builder-pattern path for bulk construction, and is an Editor command that runs arbitrary code.

```APIDOC
## run_script

### Description
Compile a single project `.cs` file in memory and execute a named static entry point. This is the builder-pattern path for bulk construction, and is an Editor command that runs arbitrary code.

### Parameters

| Parameter | Required | Default | Description |
|---|---|---|---|
| `file` | yes | `–` | Path to a `.cs` file. Relative paths resolve against the project root (the parent of `Assets/`), not the process working directory. May live outside `Assets/` (e.g. `AgentScripts/`) so writing it never triggers an asset import or domain reload. |
| `entry` | no | `–` | Entry point as `Namespace.Type.Method` (or `Type.Method`, or a bare `Method`). Nested types may be written with dots (`Outer.Inner.Method`). Default: the single public static method if unambiguous, else a method named `Main`. Static, non-generic methods only in v1. Ephemeral mode only — rejected with `mode=hotpatch`. |
| `args` | no | `–` | JSON array of arguments, coerced to the entry's parameter types: primitives, enum names, `string[]`, and a string/object handle (`ObjectRef`) for `UnityEngine.Object` parameters. JSON `null` is only valid for reference-type and nullable parameters (never a silent `default(T)`). Ephemeral mode only — rejected with `mode=hotpatch`. |
| `mode` | no | `ephemeral` | `ephemeral`: compile to an in-memory assembly, run the entry, discard. `hotpatch`: apply in-place `[CodeReload]` method replacements to already-loaded types (delegates to `reload_file`). |
| `references` | no | `–` | Extra assembly name prefixes to reference. In the Editor all loaded assemblies are already referenced, so this is effectively a no-op there. Ephemeral mode only; **not applied** by hotpatch (the compile is `reload_file`'s). |
| `defines` | no | `–` | Extra scripting define symbols, **appended to the project's active editor defines** (`EditorUserBuildSettings.activeScriptCompilationDefines`) — so `UNITY_EDITOR`, version and platform symbols are already set and sources behave like project code; your defines extend that set rather than replace it. Ephemeral mode only; **not applied** by hotpatch. |
| `pdb` | no | `false` | Emit a portable PDB mapped to the source file so breakpoints bind. Ephemeral runs always emit source-mapped symbols so exception stack traces carry `file:line`. Compiles unoptimized. |
| `timeout_ms` | no | `30000` | Timeout in milliseconds (governs the main-thread wait budget end-to-end, like `eval`). |
| `dry_run` | no | `false` | Compile only: return diagnostics; the emitted assembly is **not loaded** into the domain and nothing executes (the response carries no `assemblyName`). Rejected with `mode=hotpatch` — a hotpatch "dry run" would still apply live method replacements. |

### Returns
`RunScriptResponse` — `{ result, diagnostics, compileMs, executeMs, assemblyName }` on top of the standard envelope. The result carries no echo of the source (path + diagnostics only). Compile errors return full Roslyn diagnostics (with line/column) and execute nothing; runtime exceptions surface as structured errors with `file:line` mapped to the source file.

### Notes
- `MainThreadRequired = true`. Editor command.
- Executing runs always compile **unoptimized (Debug codegen)** so the emitted symbols keep full sequence points for `file:line` mapping — expect the generated code to run somewhat slower than regular project assemblies.
- **Async entry points** (`async Task` / `Task<T>`) are awaited to completion; `Task<T>.Result` becomes the command result and exceptions in the async work surface as runtime errors. The await is **asynchronous** — the Editor main thread keeps pumping, so awaits that resume on Unity's main-thread context (`Task.Yield()`, `Task.Delay()`, Awaitable, …) work naturally; no `ConfigureAwait(false)` contortions are required. The wait is bounded by what remains of `timeout_ms`; on expiry the command returns a `Timeout` error and the task keeps running detached (its effects may still land), like an abandoned `eval`.
- **hotpatch specifics:** `entry`, `args` and `dry_run` are rejected (Bad Request); `references` and `defines` are not applied. Path resolution follows `reload_file`, which probes under `Assets/` for bare filenames (unlike ephemeral's project-root resolution). Timing: `executeMs` carries the whole reload duration (compile + apply, not split by `reload_file`); `compileMs` is `0`. Advisory reload diagnostics are surfaced as severity-`warning` entries on success.
- Under Unity's Mono runtime the in-memory assembly emitted by an executing `ephemeral` run is **not** collectible/unloadable, so each run retains one small assembly (the same behavior as `eval`); prefer a single builder entry over many tiny runs. `dry_run` loads nothing.
