The `machine` utility uses a session ID to separate machines created by someone using the same provider API key on for example two different computers. This can be overridden but the default is to use the ID, which is stored in the file `~/.machine/session-id.yaml`. If the file does not exist then a new ID is generated and stored in a new file. The problem with this scheme is that in the local-orchestrator context the filesystem is re-created on every page load. So while secrets and config are retained in browser local storage, the session id file is not. The result is that the user can create a machine, see it listed with `machine list` then reload the page, run the same command again and the machine is not listed. 

We should persist the session id in browser local storage and perhaps also allow the user to optionally set it via config in order for them to transfer work context from another browser instance.

Perfect! Now I have a comprehensive understanding. Let me create a final summary document with all the specific line numbers and paths:

## Summary Report: Session ID, Local Storage Persistence, and Config Handling

Based on my thorough analysis of the codebase, here are the key findings:

### 1. **Virtual Filesystem Setup in worker.ts**

**File:** `/home/david/projects/stirlingbridge/local-orchestrator/src/worker.ts`

- **Lines 278-307**: `initPyodide()` function initializes the virtual filesystem
  - Line 292: Creates `/tools` directory for CLI scripts
  - Line 295: Adds `/tools` to Python's sys.path
  - Lines 299-303: Detects Python version and writes HTTP helper modules to stdlib
  
- **Lines 348-363**: `handleWriteFile()` function manages virtual filesystem writes
  - Ensures parent directories exist before creating files
  - Uses Pyodide's FS API (writeFile, mkdir, analyzePath)
  
- **Lines 361-363**: `handleReadFile()` function reads from virtual filesystem

**Important**: There is **NO persistent storage restoration in worker.ts**. The virtual filesystem is **entirely in-memory** during the Pyodide session. All file persistence happens at the higher application level.

---

### 2. **Config Files Handling**

**File:** `/home/david/projects/stirlingbridge/local-orchestrator/src/machine-config.ts`

This is the primary config management system:

- **Line 1**: Storage key is `"machine-config"`
- **Lines 28-39**: Constructor with localStorage restore logic
  - Line 29: `localStorage.getItem(STORAGE_KEY)` retrieves saved config
  - Lines 32-38: Merges stored values with DEFAULTS
  
- **Lines 45-48**: `save()` method persists to localStorage
  - Line 47: `localStorage.setItem(STORAGE_KEY, JSON.stringify(this.values))`
  
- **Lines 51-75**: `toYaml()` method generates the machine CLI config in YAML format
  - Outputs: `digital-ocean` section with API token template
  - Machine size, image, region, SSH key, DNS zone, project
  - Optional `machines` section with custom machine definitions

**File:** `/home/david/projects/stirlingbridge/local-orchestrator/src/main.ts`

- **Lines 129-131**: Initializes config on app startup
  - Creates fresh `MachineConfig()` instance which auto-restores from localStorage
  
- **Lines 136-138**: `writeMachineConfig()` writes YAML to virtual FS
  - Path: `/home/pyodide/.machine/config.yml`
  
- **Lines 140-150**: `populateConfigModal()` populates UI form fields from stored values

- **Lines 174-210**: Config modal UI event handlers
  - Lines 184-201: Save handler validates and persists config changes
  - Line 203: Writes updated YAML to virtual filesystem after save

---

### 3. **Session ID References**

**CRITICAL FINDING**: There is **NO "session-id" or "session_id" anywhere in this codebase**. 

The codebase uses a **request ID system** instead:

**File:** `/home/david/projects/stirlingbridge/local-orchestrator/src/runtime.ts`

- **Lines 16-19**: Request ID generation
  ```typescript
  let nextId = 0;
  function genId(): string {
    return `req-${++nextId}`;
  }
  ```
  
- **Lines 51-58**: `send()` method correlates requests/responses by ID
  - Stores pending requests in Map<string, PendingRequest>
  - Matches responses by ID correlation

The "~/.machine" reference appears only in:
- **main.ts, Line 137**: `/home/pyodide/.machine/config.yml` (virtual FS path, not a real home directory)
- **machine-config.ts, Lines 59-71**: YAML generation for machine CLI tool

---

### 4. **Config Editor UI**

**File:** `/home/david/projects/stirlingbridge/local-orchestrator/index.html`

**Modal structure (Lines 361-406)**:
- **Lines 362-406**: Config modal panel with form fields for:
  - Machine Size (line 370-371)
  - Image (line 373-375)
  - Region (line 377-379)
  - SSH Key (line 381-383)
  - DNS Zone (line 385-387)
  - Project (line 389-391)
  - Machine Name (line 393-395)
  - New User Name (line 397-399)
  - Save button (line 403)

**UI Elements in main.ts (Lines 18-29)**:
- DOM references for all config input fields
- Modal toggle on config button click (Lines 174-183)
- Form validation requiring machine name (Lines 185-189)

---

### 5. **Message Protocol Types**

**File:** `/home/david/projects/stirlingbridge/local-orchestrator/src/types.ts`

**WorkerRequest union type (Lines 20-25)**:
```typescript
| { id: string; type: "init" }
| { id: string; type: "exec"; scriptPath: string; args: string[]; env?: Record<string, string> }
| { id: string; type: "install"; packages: string[] }
| { id: string; type: "write-file"; path: string; content: string }
| { id: string; type: "read-file"; path: string }
```

**WorkerResponse union type (Lines 29-35)**:
```typescript
| { id: string; type: "ready" }
| { id: string; type: "exec-result"; stdout: string; stderr: string; exitCode: number }
| { id: string; type: "install-result"; success: boolean; error?: string }
| { id: string; type: "write-file-result"; success: boolean; error?: string }
| { id: string; type: "read-file-result"; success: boolean; content?: string; error?: string }
| { id: string; type: "error"; error: string }
```

**Handler implementations in worker.ts (Lines 367-425)**:
- Line 372: Message type switch statement
- Lines 373-376: "init" → initializes Pyodide
- Lines 379-388: "exec" → runs Python scripts
- Lines 391-394: "install" → installs packages via micropip
- Lines 397-400: "write-file" → writes to virtual FS
- Lines 403-411: "read-file" → reads from virtual FS

---

### 6. **Secrets Storage**

**File:** `/home/david/projects/stirlingbridge/local-orchestrator/src/secrets.ts`

Two-tier storage strategy:
- **IndexedDB**: Stores non-extractable AES-GCM encryption key
  - DB Name: `"localfirst-secrets"` (Line 9)
  - Store: `"keys"` (Line 10)
  
- **localStorage**: Stores encrypted secret values
  - Key prefix: `"secret:"` (Line 12)
  - Line 134: `localStorage.setItem(LS_PREFIX + name, encrypted)`
  - Line 111: `localStorage.getItem(LS_PREFIX + name)` retrieves encrypted values
  
- **Lines 100-106**: `keys()` method enumerates all stored secrets by scanning localStorage

---

### Key Architectural Insights

1. **No Session ID**: The app uses simple request ID correlation (`req-1`, `req-2`, etc.) instead of session IDs
2. **Browser-Local Persistence**: All data persists only in browser storage (localStorage + IndexedDB)
3. **Ephemeral Virtual FS**: Virtual filesystem is in-memory per browser session
4. **Encrypted Secrets**: Environment secrets encrypted before localStorage storage
5. **Config-to-YAML Pipeline**: MachineConfig class → YAML string → virtual FS write on demand
6. **Per-Session**: Each browser tab has its own Pyodide instance, secrets, and config

The machine CLI tool receives its config at `/home/pyodide/.machine/config.yml` when explicitly written by the UI after config changes.

src/main.ts:141:    await runtime.writeFile("/home/pyodide/.machine/config.yml", machineConfig.toYaml());

Perfect! Now I have a comprehensive understanding. Let me create a summary of my findings:

## Summary

Based on my thorough exploration of the worker.ts and runtime.ts files, along with related code in main.ts and commands.ts, here are my findings:

### **HOME Directory in Pyodide**

The Pyodide WASM environment uses `/home/pyodide/` as its home directory. This is evidenced by:

**In `/home/david/projects/stirlingbridge/local-orchestrator/src/main.ts`:**
- Line 33: `const SESSION_ID_FS_PATH = "/home/pyodide/.machine/session-id.yaml";`
- Line 141: `await runtime.writeFile("/home/pyodide/.machine/config.yml", machineConfig.toYaml());`

These hardcoded paths show that the application expects to store machine configuration and session ID files under `/home/pyodide/.machine/` directory in the Pyodide virtual filesystem.

### **HOME Environment Variable Setup**

**Critical Finding:** There is **NO explicit HOME environment variable set** in the BOOTSTRAP_PYTHON code or anywhere else in the codebase.

In `/home/david/projects/stirlingbridge/local-orchestrator/src/worker.ts`:
- The `BOOTSTRAP_PYTHON` variable (lines 24-70) only sets up `_run_command()` helper
- It imports `sys`, `io`, `runpy`, `os`, and `json` but doesn't configure HOME
- The `handleExec()` function (lines 309-338) only manages environment variables passed via the `env` parameter from the caller

### **registerGitHubCommand Flow (runtime.ts)**

In `/home/david/projects/stirlingbridge/local-orchestrator/src/runtime.ts`:
- Lines 140-184: `registerGitHubCommand()` fetches Python package files from GitHub
- Lines 167-176: Downloads all files in parallel from `raw.githubusercontent.com`
- No HOME directory or special environment setup happens during this flow
- The machine tool is registered with dependencies: `click`, `python-digitalocean`, `ruamel.yaml`, `expandvars` (line 447 in main.ts)

### **Where HOME Would Come From**

The HOME directory in Pyodide is likely:
1. **Implicitly set by Pyodide itself** to `/home/pyodide/` by default
2. **NOT explicitly configured in this codebase** — it relies on Pyodide's defaults
3. **Accessible to scripts via expandvars library** — the `expandvars` dependency suggests the machine tool may use it to expand environment variables like `${HOME}` in config files

### **No expanduser or web_user References**

As confirmed by the grep searches, there are **no references** to `expanduser`, `web_user`, or explicit HOME configuration in either worker.ts or runtime.ts.

**Files examined:**
- `/home/david/projects/stirlingbridge/local-orchestrator/src/worker.ts` (366 lines)
- `/home/david/projects/stirlingbridge/local-orchestrator/src/runtime.ts` (316 lines)
- `/home/david/projects/stirlingbridge/local-orchestrator/src/main.ts` (469 lines)
- `/home/david/projects/stirlingbridge/local-orchestrator/src/commands.ts` (145 lines)
