-# @push.rocks/npmextra
+# @push.rocks/npmextra 🚀
-A utility to enhance npm with additional configuration, tool management capabilities, and a key-value store for project setups.
 
-## Install
+**Supercharge your npm projects with powerful configuration management, tool orchestration, and persistent key-value storage.**
-To install `@push.rocks/npmextra`, use the following npm command:
+
+## Install 📦
 
 ```bash
+# Using npm
 npm install @push.rocks/npmextra --save
+
+# Using pnpm (recommended)
+pnpm add @push.rocks/npmextra
 ```
 
-This package is available on [npm](https://www.npmjs.com/package/@push.rocks/npmextra) and can be installed into your project as a dependency to enhance npm with additional configuration and tool management capabilities.
+## Overview 🎯
 
-## Usage
+`@push.rocks/npmextra` is your Swiss Army knife for npm project configuration. It eliminates configuration sprawl by centralizing tool settings, providing intelligent key-value storage, and offering powerful environment variable mapping with automatic type conversions.
-`@push.rocks/npmextra` is designed to supplement npm functionalities with enhanced configuration and tool management. It facilitates the management of project configurations and tool setups in a consolidated manner, enabling a smoother workflow and maintenance process. Below are detailed use cases and examples implemented with ESM syntax and TypeScript.
 
-### Initial Setup and Configuration
+### Why npmextra? 
-To start using `npmextra` in your project, first include it with an import statement:
+
+- **🎛️ Centralized Configuration**: Manage all your tool configs in one `npmextra.json` file
+- **💾 Persistent Storage**: Smart key-value store with multiple storage strategies
+- **🔐 Environment Mapping**: Sophisticated env var handling with automatic type conversion
+- **🏗️ TypeScript First**: Full type safety and IntelliSense support
+- **⚡ Zero Config**: Works out of the box with sensible defaults
+- **🔄 Reactive**: Built-in change detection and observables
+
+## Core Concepts 🏗️
+
+### 1. Npmextra Configuration Management
+
+Stop scattering configuration across dozens of files. Centralize everything in `npmextra.json`:
 
 ```typescript
 import { Npmextra } from '@push.rocks/npmextra';
+
+// Initialize with current directory
+const npmextra = new Npmextra();
+
+// Or specify a custom path
+const npmextra = new Npmextra('/path/to/project');
+
+// Get merged configuration for any tool
+const eslintConfig = npmextra.dataFor<EslintConfig>('eslint', {
+  // Default values if not in npmextra.json
+  extends: 'standard',
+  rules: {}
+});
 ```
 
-Instantiate the `Npmextra` class optionally with a custom path to your project's working directory. If no path is provided, the current working directory (`process.cwd()`) is used.
+**npmextra.json example:**
-
-```typescript
-const npmExtraInstance = new Npmextra('/path/to/your/project');
-```
-
-### Managing Tool Configurations with `npmextra.json`
-`@push.rocks/npmextra` excels in unifying tool configurations through a single `npmextra.json` file. Instead of scattering configurations across multiple files, `npmextra` enables you to define tool-specific settings within this centralized configuration file, which can then be accessed programmatically.
-
-#### Creating and Utilizing `npmextra.json`
-
-Create a `npmextra.json` in your project root with the following structure:
-
 ```json
 {
-  "toolname": {
+  "eslint": {
-    "setting1": "value1",
+    "extends": "@company/eslint-config",
-    "setting2": "value2"
+    "rules": {
+      "no-console": "warn"
+    }
+  },
+  "prettier": {
+    "semi": false,
+    "singleQuote": true
   }
 }
 ```
 
-For example, to configure a hypothetical tool named `toolname`, define its settings as shown above.
+### 2. KeyValueStore - Persistent Data Storage
 
-#### Accessing Configuration in Your Project
+A flexible key-value store that persists data between script executions:
-
-With the configuration defined, you can easily access these settings in your TypeScript code as follows:
-
-```typescript
-// Import the npmextra module
-import { Npmextra } from '@push.rocks/npmextra';
-
-// Create an instance pointing at the current directory
-const npmExtraInstance = new Npmextra();
-
-// Retrieve the configuration for 'toolname', merging defaults with any found in npmextra.json
-const toolConfig = npmExtraInstance.dataFor<{ setting1: string, setting2: string }>('toolname', {
-  setting1: 'defaultValue1',
-  setting2: 'defaultValue2'
-});
-
-// toolConfig now contains the merged settings from npmextra.json and provided defaults
-console.log(toolConfig);
-```
-
-### Key-Value Store Management
-`@push.rocks/npmextra` also includes a Key-Value Store (KeyValueStore) functionality enabling persistent storage of key-value pairs between script executions.
-
-#### Setting Up KeyValueStore
-
-To utilize the KeyValueStore, create an instance specifying its scope (e.g., 'userHomeDir') and a unique identity for your application or tool:
 
 ```typescript
 import { KeyValueStore } from '@push.rocks/npmextra';
 
-const kvStore = new KeyValueStore<'userHomeDir'>({
+interface UserSettings {
-  typeArg: 'userHomeDir', 
+  username: string;
-  identityArg: 'myUniqueAppName'
+  apiKey: string;
+  preferences: {
+    theme: 'light' | 'dark';
+    notifications: boolean;
+  };
+}
+
+// Different storage strategies
+const kvStore = new KeyValueStore<UserSettings>({
+  typeArg: 'userHomeDir',  // Store in user's home directory
+  identityArg: 'myApp',
+  mandatoryKeys: ['username', 'apiKey']
 });
-```
 
-You can then use the `writeKey`, `readKey`, `writeAll`, and `readAll` methods to manage your store respectively.
+// Write operations
+await kvStore.writeKey('username', 'john_doe');
+await kvStore.writeKey('preferences', {
+  theme: 'dark',
+  notifications: true
+});
 
-#### Example: Storing and Retrieving Data
+// Read operations
-
-```typescript
-// Write a single key-value pair
-await kvStore.writeKey('username', 'johnDoe');
-
-// Read a single key
 const username = await kvStore.readKey('username');
-console.log(username); // Outputs: johnDoe
-
-// Write multiple key-value pairs
-await kvStore.writeAll({
-  email: 'john@example.com',
-  isAdmin: true
-});
-
-// Read all key-value pairs
 const allData = await kvStore.readAll();
-console.log(allData); // Outputs the entire store's contents
-```
 
-### Advanced Key-Value Store Management
+// Check for missing mandatory keys
-
-In addition to basic read/write operations, `npmextra`’s `KeyValueStore` supports advanced scenarios like mandatory keys and custom file paths.
-
-#### Example: Mandatory Keys and Custom Paths
-
-Consider a scenario where your application requires specific keys to be present in the KeyValueStore. You can define mandatory keys and use a custom path for your store like this:
-
-```typescript
-import { KeyValueStore } from '@push.rocks/npmextra';
-
-interface CustomData {
-  key1: string;
-  key2: number;
-  key3?: boolean;
-}
-
-const kvStore = new KeyValueStore<CustomData>({
-  typeArg: 'custom',
-  identityArg: 'customApp',
-  customPath: '/custom/path/to/store.json',
-  mandatoryKeys: ['key1', 'key2']
-});
-
-// Ensure all mandatory keys are present
 const missingKeys = await kvStore.getMissingMandatoryKeys();
-if (missingKeys.length) {
+if (missingKeys.length > 0) {
-  console.log(`Missing mandatory keys: ${missingKeys.join(', ')}`);
+  console.log('Missing required configuration:', missingKeys);
 }
 
-// Use the KeyValueStore
+// Wait for keys to be present
-await kvStore.writeKey('key1', 'value1');
+await kvStore.waitForKeysPresent(['apiKey']);
-await kvStore.writeKey('key2', 123);
-
-const key1Value = await kvStore.readKey('key1');
-const allData = await kvStore.readAll();
-
-console.log(key1Value); // Outputs: value1
-console.log(allData); // Outputs: { key1: 'value1', key2: 123 }
 ```
 
-### Combining AppData and KeyValueStore
+**Storage Types:**
+- `userHomeDir`: Store in user's home directory
+- `custom`: Specify your own path
+- `ephemeral`: In-memory only (perfect for testing)
 
-The `AppData` class extends the functionality of `KeyValueStore` by integrating environmental variables, specifying additional configurations, and providing a more structured approach to data management.
+### 3. AppData - Advanced Environment Management 🌟
 
-#### Example: AppData Usage
+The crown jewel of npmextra - sophisticated environment variable mapping with automatic type conversion:
 
 ```typescript
 import { AppData } from '@push.rocks/npmextra';
 
-interface AppSettings {
+interface AppConfig {
-  settingA: string;
+  apiUrl: string;
-  settingB: number;
+  apiKey: string;
-  nestedSetting: {
+  port: number;
-    innerSetting: boolean;
+  features: {
-  }
+    analytics: boolean;
+    payment: boolean;
+  };
+  cache: {
+    ttl: number;
+    redis: {
+      host: string;
+      password: string;
+    };
+  };
 }
 
-const appDataInstance = await AppData.createAndInit<AppSettings>({
+const appData = await AppData.createAndInit<AppConfig>({
-  dirPath: '/custom/path/to/appdata',
+  dirPath: '/app/config',  // Optional: defaults to smart path selection
-  requiredKeys: ['settingA', 'settingB'],
+  requiredKeys: ['apiKey', 'apiUrl'],
   envMapping: {
-    settingA: 'MY_ENV_A',
+    apiUrl: 'API_URL',                    // Simple mapping
-    settingB: 'hard:42',
+    apiKey: 'hard:development-key-123',   // Hardcoded value
-    nestedSetting: {
+    port: 'hard:3000',                     // Hardcoded number
-      innerSetting: 'MY_ENV_INNER'
+    features: {
+      analytics: 'boolean:ENABLE_ANALYTICS',  // Force boolean conversion
+      payment: 'hard_boolean:true'            // Hardcoded boolean
+    },
+    cache: {
+      ttl: 'json:CACHE_CONFIG',  // Parse JSON from env var
+      redis: {
+        host: 'REDIS_HOST',
+        password: 'base64:REDIS_PASSWORD_B64'  // Decode base64
+      }
+    }
+  },
+  overwriteObject: {
+    // Force these values regardless of env vars
+    port: 8080
+  }
+});
+
+const store = await appData.getKvStore();
+const apiUrl = await store.readKey('apiUrl');
+```
+
+## AppData Special Cases & Conversions 🎯
+
+### Environment Variable Prefixes
+
+AppData supports sophisticated type conversion through prefixes:
+
+| Prefix | Description | Example | Result |
+|--------|-------------|---------|--------|
+| `hard:` | Hardcoded value | `hard:myvalue` | `"myvalue"` |
+| `hard_boolean:` | Hardcoded boolean | `hard_boolean:true` | `true` |
+| `hard_json:` | Hardcoded JSON | `hard_json:{"key":"value"}` | `{key: "value"}` |
+| `hard_base64:` | Hardcoded base64 | `hard_base64:SGVsbG8=` | `"Hello"` |
+| `boolean:` | Env var as boolean | `boolean:FEATURE_FLAG` | `true/false` |
+| `json:` | Parse env var as JSON | `json:CONFIG_JSON` | Parsed object |
+| `base64:` | Decode env var from base64 | `base64:SECRET_B64` | Decoded string |
+
+### Automatic Suffix Detection
+
+Variables ending with certain suffixes get automatic conversion:
+
+```typescript
+{
+  envMapping: {
+    // Automatically parsed as JSON if MY_CONFIG_JSON="{"enabled":true}"
+    config: 'MY_CONFIG_JSON',
+    
+    // Automatically decoded from base64 if SECRET_KEY_BASE64="SGVsbG8="
+    secret: 'SECRET_KEY_BASE64'
+  }
+}
+```
+
+### Complex Examples
+
+```typescript
+const appData = await AppData.createAndInit({
+  envMapping: {
+    // Simple environment variable
+    apiUrl: 'API_URL',
+    
+    // Hardcoded values with type conversion
+    debugMode: 'hard_boolean:false',
+    maxRetries: 'hard:5',
+    defaultConfig: 'hard_json:{"timeout":30,"retries":3}',
+    
+    // Environment variables with conversion
+    features: 'json:FEATURE_FLAGS',  // Expects: {"feature1":true,"feature2":false}
+    isProduction: 'boolean:IS_PROD', // Expects: "true" or "false"
+    apiSecret: 'base64:API_SECRET',  // Expects: base64 encoded string
+    
+    // Nested structures
+    database: {
+      host: 'DB_HOST',
+      port: 'hard:5432',
+      credentials: {
+        user: 'DB_USER',
+        password: 'base64:DB_PASSWORD_ENCODED',
+        ssl: 'boolean:DB_USE_SSL'
+      }
+    }
+  },
+  
+  // Override any env mappings
+  overwriteObject: {
+    debugMode: true,  // Force debug mode regardless of env
+    database: {
+      host: 'localhost'  // Force localhost for development
     }
   }
 });
-
-const appDataKvStore = await appDataInstance.getKvStore();
-
-// Writing values
-await appDataKvStore.writeKey('settingA', 'exampleValue');
-await appDataKvStore.writeKey('settingB', 100);
-await appDataKvStore.writeKey('nestedSetting', { innerSetting: true });
-
-// Reading values
-const settingA = await appDataKvStore.readKey('settingA');
-const allSettings = await appDataKvStore.readAll();
-
-console.log(settingA); // Outputs: 'exampleValue'
-console.log(allSettings); // Outputs: { settingA: 'exampleValue', settingB: 100, nestedSetting: { innerSetting: true } }
 ```
 
-### Error Handling and Debugging
+### Boolean Conversion Rules
 
-Proper error handling ensures your integrations with `npmextra` are robust and stable. Below are some strategies for error handling and debugging potential issues.
+AppData intelligently handles boolean conversions:
 
-#### Example: Error Handling in KeyValueStore
+1. **String "true"/"false"**: Converted to boolean
+2. **With `boolean:` prefix**: Any env var value is converted (`"true"` → `true`, anything else → `false`)
+3. **With `hard_boolean:` prefix**: Hardcoded boolean value
+4. **Regular env vars**: Strings remain strings unless prefixed
 
 ```typescript
-import { KeyValueStore } from '@push.rocks/npmextra';
+// Environment: FEATURE_A="true", FEATURE_B="yes", FEATURE_C="1"
-
+{
-const kvStore = new KeyValueStore('userHomeDir', 'errorHandlingApp');
+  envMapping: {
-
+    featureA: 'FEATURE_A',           // Result: "true" (string)
-try {
+    featureB: 'boolean:FEATURE_B',   // Result: false (only "true" → true)
-  await kvStore.writeKey('importantKey', 'importantValue');
+    featureC: 'boolean:FEATURE_C',   // Result: false (only "true" → true)
-  const value = await kvStore.readKey('importantKey');
+    featureD: 'hard_boolean:true'    // Result: true (hardcoded)
-  console.log(value); // Outputs: importantValue
+  }
-} catch (error) {
-  console.error('Error managing key-value store:', error);
 }
 ```
 
-#### Debugging Configuration Issues in `npmextra.json`
+### Static Helper Functions
 
-To debug configuration issues, you can utilize conditional logging and checks:
+AppData provides convenient static methods for directly accessing and converting environment variables without creating an instance:
 
 ```typescript
-import { Npmextra } from '@push.rocks/npmextra';
+import { AppData } from '@push.rocks/npmextra';
 
-const npmExtraInstance = new Npmextra();
+// Get environment variable as boolean
-const toolConfig = npmExtraInstance.dataFor('toolname', {
+const isEnabled = await AppData.valueAsBoolean('FEATURE_ENABLED');
-  configKey1: 'defaultValue1',
+// Returns: true if "true", false otherwise
-  configKey2: 'defaultValue2'
+
+// Get environment variable as parsed JSON
+interface Config {
+  timeout: number;
+  retries: number;
+}
+const config = await AppData.valueAsJson<Config>('SERVICE_CONFIG');
+// Returns: Parsed object or undefined
+
+// Get environment variable as base64 decoded string
+const secret = await AppData.valueAsBase64('ENCODED_SECRET');
+// Returns: Decoded string or undefined
+
+// Get environment variable as string
+const apiUrl = await AppData.valueAsString('API_URL');
+// Returns: String value or undefined
+
+// Get environment variable as number
+const port = await AppData.valueAsNumber('PORT');
+// Returns: Number value or undefined
+```
+
+These static methods are perfect for:
+- Quick environment variable access without setup
+- Simple type conversions in utility functions
+- One-off configuration checks
+- Scenarios where you don't need the full AppData instance
+
+## Advanced Patterns 🎨
+
+### Reactive Configuration
+
+Subscribe to configuration changes:
+
+```typescript
+const kvStore = new KeyValueStore<Config>({
+  typeArg: 'custom',
+  identityArg: 'myApp'
 });
 
-if (!toolConfig.configKey1) {
+// Subscribe to changes
-  console.error('configKey1 is missing in npmextra.json');
+kvStore.changeSubject.subscribe((newData) => {
+  console.log('Configuration changed:', newData);
+});
+
+// Changes trigger notifications
+await kvStore.writeKey('theme', 'dark');
+```
+
+### Testing with Ephemeral Storage
+
+Perfect for unit tests - no file system pollution:
+
+```typescript
+const testStore = new KeyValueStore<TestData>({
+  typeArg: 'ephemeral',
+  identityArg: 'test'
+});
+
+// All operations work normally, but nothing persists to disk
+await testStore.writeKey('testKey', 'testValue');
+```
+
+### Smart Path Resolution
+
+AppData automatically selects the best storage location:
+
+1. Checks for `/app/data` (containerized environments)
+2. Falls back to `/data` (alternate container path)
+3. Uses `.nogit/appdata` (local development)
+
+```typescript
+// Automatic path selection
+const appData = await AppData.createAndInit({
+  // No dirPath specified - smart detection
+  requiredKeys: ['apiKey']
+});
+
+// Or force ephemeral for testing
+const testData = await AppData.createAndInit({
+  ephemeral: true,  // No disk persistence
+  requiredKeys: ['testKey']
+});
+```
+
+### Waiting for Configuration
+
+Block until required configuration is available:
+
+```typescript
+const appData = await AppData.createAndInit<Config>({
+  requiredKeys: ['apiKey', 'apiUrl']
+});
+
+// Wait for specific key
+const apiKey = await appData.waitForAndGetKey('apiKey');
+
+// Check missing keys
+const missingKeys = await appData.logMissingKeys();
+// Logs: "The following mandatory keys are missing in the appdata:
+//        -> apiKey,
+//        -> apiUrl"
+```
+
+## Real-World Example 🌍
+
+Here's a complete example of a CLI tool using npmextra:
+
+```typescript
+import { Npmextra, AppData, KeyValueStore } from '@push.rocks/npmextra';
+
+interface CliConfig {
+  githubToken: string;
+  openaiKey: string;
+  model: 'gpt-3' | 'gpt-4';
+  cache: {
+    enabled: boolean;
+    ttl: number;
+  };
 }
 
-console.log(toolConfig);
+class MyCLI {
+  private npmextra: Npmextra;
+  private appData: AppData<CliConfig>;
+  private cache: KeyValueStore<{[key: string]: any}>;
+
+  async initialize() {
+    // Load tool configuration
+    this.npmextra = new Npmextra();
+    const config = this.npmextra.dataFor<any>('mycli', {
+      defaultModel: 'gpt-3'
+    });
+
+    // Setup app data with env mapping
+    this.appData = await AppData.createAndInit<CliConfig>({
+      requiredKeys: ['githubToken', 'openaiKey'],
+      envMapping: {
+        githubToken: 'GITHUB_TOKEN',
+        openaiKey: 'base64:OPENAI_KEY_ENCODED',
+        model: 'hard:gpt-4',
+        cache: {
+          enabled: 'boolean:ENABLE_CACHE',
+          ttl: 'hard:3600'
+        }
+      }
+    });
+
+    // Initialize cache
+    this.cache = new KeyValueStore({
+      typeArg: 'userHomeDir',
+      identityArg: 'mycli-cache'
+    });
+
+    // Check for missing configuration
+    const missingKeys = await this.appData.logMissingKeys();
+    if (missingKeys.length > 0) {
+      console.error('Please configure the missing keys');
+      process.exit(1);
+    }
+  }
+
+  async run() {
+    await this.initialize();
+    
+    const config = await this.appData.getKvStore();
+    const settings = await config.readAll();
+    
+    console.log(`Using model: ${settings.model}`);
+    console.log(`Cache enabled: ${settings.cache.enabled}`);
+    
+    // Use the configuration...
+  }
+}
+
+// Run the CLI
+const cli = new MyCLI();
+cli.run();
 ```

+# AppData Refactoring Plan
+
+## Overview
+Refactor the AppData class to improve elegance, maintainability, and extensibility while maintaining 100% backward compatibility.
+
+## Current Issues
+- 100+ lines of nested switch statements in processEnvMapping
+- Static helpers recreate Qenv instances on every call
+- Complex boolean conversion logic scattered across multiple places
+- Typo: "ephermal" should be "ephemeral"
+- Difficult to test and extend with new transformations
+
+## Architecture Improvements
+
+### 1. Singleton Qenv Provider
+Create a shared Qenv instance to avoid repeated instantiation:
+
+```typescript
+let sharedQenv: plugins.qenv.Qenv | undefined;
+
+function getQenv(): plugins.qenv.Qenv {
+  if (!sharedQenv) {
+    sharedQenv = new plugins.qenv.Qenv(
+      process.cwd(),
+      plugins.path.join(process.cwd(), '.nogit')
+    );
+  }
+  return sharedQenv;
+}
+```
+
+### 2. Centralized Type Converters
+Extract all conversion logic into pure utility functions:
+
+```typescript
+function toBoolean(value: unknown): boolean {
+  if (typeof value === 'boolean') return value;
+  if (value == null) return false;
+  const s = String(value).toLowerCase();
+  return s === 'true';
+}
+
+function toJson<T>(value: unknown): T | undefined {
+  if (typeof value === 'string') {
+    try {
+      return JSON.parse(value);
+    } catch {
+      return undefined;
+    }
+  }
+  return value as T;
+}
+
+function fromBase64(value: unknown): string {
+  if (value == null) return '';
+  return Buffer.from(String(value), 'base64').toString('utf8');
+}
+
+function toNumber(value: unknown): number | undefined {
+  if (value == null) return undefined;
+  const num = Number(value);
+  return Number.isNaN(num) ? undefined : num;
+}
+
+function toString(value: unknown): string | undefined {
+  if (value == null) return undefined;
+  return String(value);
+}
+```
+
+### 3. Declarative Pipeline Architecture
+
+Replace the giant switch statement with a composable pipeline:
+
+#### Data Structures
+```typescript
+type MappingSpec = {
+  source: 
+    | { type: 'env', key: string }
+    | { type: 'hard', value: string };
+  transforms: Transform[];
+}
+
+type Transform = 'boolean' | 'json' | 'base64' | 'number';
+```
+
+#### Pipeline Functions
+```typescript
+// Parse mapping string into spec
+function parseMappingSpec(input: string): MappingSpec
+
+// Resolve the source value
+async function resolveSource(source: MappingSpec['source']): Promise<unknown>
+
+// Apply transformations
+function applyTransforms(value: unknown, transforms: Transform[]): unknown
+
+// Complete pipeline
+async function processMappingValue(mappingString: string): Promise<unknown>
+```
+
+### 4. Transform Registry
+Enable easy extension with new transforms:
+
+```typescript
+const transformRegistry: Record<string, (v: unknown) => unknown> = {
+  boolean: toBoolean,
+  json: toJson,
+  base64: fromBase64,
+  number: toNumber,
+};
+```
+
+### 5. Simplified processEnvMapping
+Build pure object tree first, then write to kvStore:
+
+```typescript
+async function evaluateMappingValue(mappingValue: any): Promise<any> {
+  if (typeof mappingValue === 'string') {
+    return processMappingValue(mappingValue);
+  }
+  if (mappingValue && typeof mappingValue === 'object') {
+    const out: any = {};
+    for (const [k, v] of Object.entries(mappingValue)) {
+      out[k] = await evaluateMappingValue(v);
+    }
+    return out;
+  }
+  return undefined;
+}
+
+// Main loop becomes:
+for (const key in this.options.envMapping) {
+  const evaluated = await evaluateMappingValue(this.options.envMapping[key]);
+  if (evaluated !== undefined) {
+    await this.kvStore.writeKey(key as keyof T, evaluated);
+  }
+}
+```
+
+## Backward Compatibility
+
+### Supported Prefixes (Maintained)
+- `hard:` - Hardcoded value
+- `hard_boolean:` - Hardcoded boolean
+- `hard_json:` - Hardcoded JSON
+- `hard_base64:` - Hardcoded base64
+- `boolean:` - Environment variable as boolean
+- `json:` - Environment variable as JSON
+- `base64:` - Environment variable as base64
+
+### Supported Suffixes (Maintained)
+- `_JSON` - Auto-parse as JSON
+- `_BASE64` - Auto-decode from base64
+
+### Typo Fix Strategy
+- Add `ephemeral` option to interface
+- Keep reading `ephermal` for backward compatibility
+- Log deprecation warning when old spelling is used
+
+## Implementation Steps
+
+1. **Add utility functions** at the top of the file
+2. **Implement pipeline functions** (parseMappingSpec, resolveSource, applyTransforms)
+3. **Refactor processEnvMapping** to use the pipeline
+4. **Update static helpers** to use shared utilities
+5. **Fix typo** with compatibility shim
+6. **Add error boundaries** for better error reporting
+7. **Test** to ensure backward compatibility
+
+## Benefits
+
+### Code Quality
+- **70% reduction** in processEnvMapping complexity
+- **Better separation** of concerns
+- **Easier testing** - each function is pure and testable
+- **Cleaner error handling** with boundaries
+
+### Performance
+- **Shared Qenv instance** reduces allocations
+- **Optional parallelization** with Promise.all
+- **Fewer repeated operations**
+
+### Maintainability
+- **Extensible** - Easy to add new transforms
+- **Readable** - Clear pipeline flow
+- **Debuggable** - Each step can be logged
+- **Type-safe** - Better TypeScript support
+
+## Testing Strategy
+
+1. **Unit tests** for each utility function
+2. **Integration tests** for the full pipeline
+3. **Backward compatibility tests** for all existing prefixes/suffixes
+4. **Edge case tests** for error conditions
+
+## Future Extensions
+
+With the transform registry, adding new features becomes trivial:
+
+```typescript
+// Add YAML support
+transformRegistry['yaml'] = (v) => YAML.parse(String(v));
+
+// Add integer parsing
+transformRegistry['int'] = (v) => parseInt(String(v), 10);
+
+// Add custom transformers
+transformRegistry['uppercase'] = (v) => String(v).toUpperCase();
+```
+
+## Migration Path
+
+1. Implement new architecture alongside existing code
+2. Gradually migrate internal usage
+3. Mark old patterns as deprecated (with warnings)
+4. Remove deprecated code in next major version
+
+## Success Metrics
+
+- All existing tests pass
+- No breaking changes for users
+- Reduced code complexity (measurable via cyclomatic complexity)
+- Improved test coverage
+- Better performance (fewer allocations, optional parallelization)
