+refresh project documentation and migrate smartconfig tool configuration keys
+
+- rewrites the README with a clearer quick start, updated class documentation, and issue reporting guidance
+- updates .smartconfig.json to use scoped tool configuration keys and adds release registry settings
+- adds a standalone MIT license file to the repository
+
+## 2025-08-16 - 5.3.3 - fix(appdata)
+Redact sensitive values in AppData logs and add redaction tests
+
+- Add redactSensitiveValue helper in AppData to mask secrets (API keys, tokens, passwords, JWTs, etc.) during logging.
+- Use redaction when logging raw and final mapping values in processMappingValue and nested key logging to avoid leaking sensitive data.
+- Improve log output for long or special values (JWT/base64 detection, length-aware previews) while preserving actual stored values.
+- Add test/test.redaction.ts to verify sensitive environment values are redacted in console output but still stored correctly in the kv store.
+- Add local config .claude/settings.local.json (editor/CI permissions/settings).
+
+## 2025-08-16 - 5.3.2 - fix(dependencies)
+Bump @push.rocks/qenv to ^6.1.3 and add local Claude settings
+
+- Bumped dependency @push.rocks/qenv from ^6.1.2 to ^6.1.3 in package.json

+
+## 2025-08-15 - 5.3.1 - fix(AppData/Conversion)
+Improve boolean conversion and mapping evaluation in AppData, ensuring falsy values (like false, 0, and empty strings) are correctly handled and logged. Also, reduce test timeout and add local permissions settings for development.
+
+- Enhanced toBoolean and evaluateMappingValue functions to properly preserve and log falsy values.
+- Added detailed logging for mapping spec processing and nested key evaluations.
+- Reduced test timeout in package.json for faster CI feedback.

+## Install 📦
 
 ```bash
-npm install @push.rocks/npmextra --save
+npm install @push.rocks/smartconfig --save
+# or
+pnpm add @push.rocks/smartconfig
 ```
 
-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.
+## Quick Start ⚡
-
-## Usage
-`@push.rocks/npmextra` is designed to supplement npm functionalities with enhanced configuration and tool management. It facilitates managing 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
-To start using npmextra in your project, first include it in your project with an import statement:
 
 ```typescript
-import { Npmextra } from '@push.rocks/npmextra';
+import { Smartconfig, AppData, KeyValueStore } from '@push.rocks/smartconfig';
+
+// 1. Read tool config from .smartconfig.json
+const sc = new Smartconfig();
+const eslintOpts = sc.dataFor('eslint', { extends: 'standard' });
+
+// 2. Map env vars to typed config (with auto-conversion)
+const appData = await AppData.createAndInit<{ port: number; debug: boolean }>({
+  envMapping: {
+    port: 'PORT',
+    debug: 'boolean:DEBUG',
+  },
+});
+
+// 3. Persist data between runs
+const kv = new KeyValueStore({ typeArg: 'userHomeDir', identityArg: 'myapp' });
+await kv.writeKey('lastRun', Date.now());
 ```
 
-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.
+## Three Core Classes 🏗️
+
+### 1. `Smartconfig` — Centralized Tool Configuration
+
+Reads a `.smartconfig.json` file from a project directory and merges its contents with your defaults. One file, every tool.
 
 ```typescript
-const npmExtraInstance = new Npmextra('/path/to/your/project');
+import { Smartconfig } from '@push.rocks/smartconfig';
+
+const sc = new Smartconfig();              // uses cwd
+const sc2 = new Smartconfig('/my/project'); // or specify a path
+
+const prettierConfig = sc.dataFor<PrettierConfig>('prettier', {
+  semi: false,
+  singleQuote: true,
+});
 ```
 
-### Managing Tool Configurations with `npmextra.json`
+**`.smartconfig.json`** example:
-`@push.rocks/npmextra` excels in unifying tool configurations through a single `npmextra.json` file. Instead of scattering configurations across multiple files, `@push.rocks/npmextra` enables you to define tool-specific settings within this centralized configuration file.
-
-#### Creating and Utilizing `npmextra.json`
-
-Create a `npmextra.json` in your project root with the following structure:
 
 ```json
 {
-  "toolname": {
+  "prettier": {
-    "setting1": "value1",
+    "semi": true,
-    "setting2": "value2"
+    "printWidth": 120
+  },
+  "eslint": {
+    "extends": "@company/eslint-config"
   }
 }
 ```
 
-For example, to configure a hypothetical tool named `toolname`, define its settings as shown above.
+Values from the file override the defaults you pass in. Missing keys fall back to your defaults.
 
-#### Accessing Configuration in Your Project
+**Properties:**
+- `smartconfigJsonExists: boolean` — whether `.smartconfig.json` was found
+- `smartconfigJsonData: any` — the parsed JSON contents
 
-With the configuration defined, you can easily access these settings in your TypeScript code as follows:
+**Methods:**
+- `dataFor<T>(toolName: string, defaults: T): T` — returns merged config
+
+---
+
+### 2. `KeyValueStore<T>` — Persistent Data Storage
+
+A generic, typed key-value store that persists JSON to disk (or stays in-memory for tests). Supports change detection via RxJS observables.
 
 ```typescript
-// import the npmextra module
+import { KeyValueStore } from '@push.rocks/smartconfig';
-import { Npmextra } from '@push.rocks/npmextra';
 
-// create an instance pointing at the current directory
+interface Settings {
-const npmExtraInstance = new Npmextra();
+  username: string;
+  theme: 'light' | 'dark';

-const toolConfig = npmExtraInstance.dataFor('toolname', {
+const kv = new KeyValueStore<Settings>({
-  defaultKey1: 'defaultValue1',
+  typeArg: 'userHomeDir',
-  defaultKey2: 'defaultValue2'
+  identityArg: 'myApp',

 ```
 
-### Key-Value Store Management
+**Storage types:**
-`@push.rocks/npmextra` also includes a Key-Value Store (KeyValueStore) functionality enabling persistent storage of key-value pairs between script executions.
 
-#### Setting Up KeyValueStore
+| `typeArg` | Where it goes | Use case |
+|-----------|--------------|----------|
+| `'userHomeDir'` | `~/.smartconfig/kv/<identity>.json` | CLI tools, per-user state |
+| `'custom'` | Your path (file or directory) | App data, project-local state |
+| `'ephemeral'` | Memory only — nothing on disk | Tests |
 
-To utilize the KeyValueStore, create an instance specifying its scope (e.g., 'userHomeDir') and a unique identity for your application or tool:
+**Methods:**
+
+| Method | Description |
+|--------|------------|
+| `readKey(key)` | Read a single value |
+| `writeKey(key, value)` | Write a single value |
+| `readAll()` | Read everything |
+| `writeAll(obj)` | Merge an object into the store |
+| `deleteKey(key)` | Remove a key |
+| `reset()` | Wipe all keys (synced to disk) |
+| `wipe()` | Delete the backing file entirely |
+| `getMissingMandatoryKeys()` | Returns keys declared mandatory but not yet set |
+| `waitForKeysPresent(keys)` | Returns a Promise that resolves once all listed keys exist |
+| `waitForAndGetKey(key)` | Waits for a key, then returns its value |
+
+---
+
+### 3. `AppData<T>` — Environment Variable Mapping 🌟
+
+The flagship class. Maps environment variables (or hardcoded values) into a typed config object with automatic type conversions, nested object support, and smart storage path selection.
 
 ```typescript
-import { KeyValueStore } from '@push.rocks/npmextra';
+import { AppData } from '@push.rocks/smartconfig';
 
-const kvStore = new KeyValueStore<'userHomeDir'>('userHomeDir', 'myUniqueAppName');
+interface Config {
-```
+  apiUrl: string;
+  apiKey: string;
+  features: {
+    analytics: boolean;
+    payment: boolean;
+  };
+  redis: {
+    host: string;
+    password: string;
+  };
+}
 
-You can then use the `writeKey`, `readKey`, `writeAll`, and `readAll` methods to manage your store respectively.
+const appData = await AppData.createAndInit<Config>({
-
+  requiredKeys: ['apiKey'],
-#### Example: Storing and Retrieving Data
+  envMapping: {
-
+    apiUrl: 'API_URL',                        // plain env var
-```typescript
+    apiKey: 'hard:dev-key-123',               // hardcoded fallback
-// Write a single key-value pair
+    features: {
-await kvStore.writeKey('username', 'johnDoe');
+      analytics: 'boolean:ENABLE_ANALYTICS',  // converts "true"/"false" → boolean
-
+      payment: 'hard_boolean:true',           // hardcoded boolean
-// Read a single key
+    },
-const username = await kvStore.readKey('username');
+    redis: {
-console.log(username); // Outputs: johnDoe
+      host: 'REDIS_HOST',
-
+      password: 'base64:REDIS_PASSWORD_B64',  // base64-decode at load time
-// Write multiple key-value pairs
+    },
-await kvStore.writeAll({
+  },
-  email: 'john@example.com',
+  overwriteObject: {
-  isAdmin: true
+    apiUrl: 'http://localhost:3000',           // force override after env mapping
+  },
 });
 
-// Read all key-value pairs
+const store = await appData.getKvStore();
-const allData = await kvStore.readAll();
+const url = await store.readKey('apiUrl');
-console.log(allData); // Outputs the entire store's contents
 ```
 
-### Integrating with Tools
+#### Mapping Prefixes
-`@push.rocks/npmextra` seamlessly integrates with numerous tools, enabling them to leverage `npmextra.json` for configuration purposes. Tools such as `npmts`, `npmci`, and `npmdocker` are already utilizing this feature for enhanced configuration management.
 
-For tool developers, integrating with `npmextra` requires reading the tool-specific configuration from `npmextra.json` and adjusting the tool's behavior based on these settings. This creates a unified and streamlined configuration process across different tools used within a project.
+| Prefix | What it does | Example mapping | Result |
+|--------|-------------|-----------------|--------|
+| *(none)* | Raw env var as string | `'MY_VAR'` | `process.env.MY_VAR` |
+| `hard:` | Hardcoded string | `'hard:hello'` | `"hello"` |
+| `boolean:` | Env var → `true`/`false` | `'boolean:FLAG'` | `true` or `false` |
+| `json:` | Env var → `JSON.parse()` | `'json:CONFIG'` | parsed object |
+| `base64:` | Env var → base64 decode | `'base64:SECRET'` | decoded string |
+| `hard_boolean:` | Hardcoded boolean | `'hard_boolean:false'` | `false` |
+| `hard_json:` | Hardcoded JSON | `'hard_json:{"a":1}'` | `{ a: 1 }` |
+| `hard_base64:` | Hardcoded base64 | `'hard_base64:SGVsbG8='` | `"Hello"` |
 
-### Conclusion
+Suffix detection also works: a mapping ending in `_JSON` or `_BASE64` triggers the corresponding transform automatically.
-By centralizing configuration management and offering a versatile key-value store, `@push.rocks/npmextra` significantly simplifies the setup and management of tools and settings in modern JavaScript and TypeScript projects. Whether you're managing project-wide configurations or need persistent storage for key-value pairs, `@push.rocks/npmextra` provides an efficient and streamlined solution.
+
+#### Boolean Conversion Rules
+
+The `boolean:` prefix (and `hard_boolean:`) recognizes:
+
+- **true**: `"true"`, `"1"`, `"yes"`, `"y"`, `"on"` (case-insensitive)
+- **false**: `"false"`, `"0"`, `"no"`, `"n"`, `"off"` (case-insensitive)
+
+#### Nested Objects
+
+Mapping values can be objects — they are resolved recursively:
+
+```typescript
+envMapping: {
+  database: {
+    host: 'DB_HOST',
+    port: 'hard:5432',
+    credentials: {
+      user: 'DB_USER',
+      password: 'base64:DB_PASS_B64',
+      ssl: 'boolean:DB_SSL',
+    },
+  },
+}
+```
+
+#### Smart Storage Path
+
+When no `dirPath` is specified, AppData auto-selects:
+
+1. `/app/data` — if it exists (containers)
+2. `/data` — if it exists (alternate container path)
+3. `.nogit/appdata` — local dev fallback
+
+Or pass `ephemeral: true` for zero disk I/O (great for tests).
+
+#### Static Helpers
+
+Quick one-shot env var reads without creating an AppData instance:
+
+```typescript
+const isEnabled = await AppData.valueAsBoolean('FEATURE_FLAG');
+const config    = await AppData.valueAsJson<MyType>('CONFIG_JSON');
+const secret    = await AppData.valueAsBase64('ENCODED_SECRET');
+const url       = await AppData.valueAsString('API_URL');
+const port      = await AppData.valueAsNumber('PORT');
+```
+
+#### Instance Methods
+
+| Method | Description |
+|--------|------------|
+| `getKvStore()` | Returns the underlying `KeyValueStore<T>` |
+| `logMissingKeys()` | Logs and returns any required keys that are missing |
+| `waitForAndGetKey(key)` | Blocks until a key is present, then returns it |
+
+---
+
+## Security 🔐
+
+AppData automatically redacts sensitive values in its console logs. Keys matching patterns like `secret`, `token`, `password`, `api`, `auth`, `jwt`, etc. are truncated. JWT tokens (starting with `eyJ`) are also detected and shortened. Your actual stored values are never modified — only log output is redacted.
+
+---
+
+## Real-World Example 🌍
+
+```typescript
+import { Smartconfig, AppData, KeyValueStore } from '@push.rocks/smartconfig';
+
+interface CliConfig {
+  githubToken: string;
+  model: 'gpt-3' | 'gpt-4';
+  cache: { enabled: boolean; ttl: number };
+}
+
+// Tool-level config from .smartconfig.json
+const sc = new Smartconfig();
+const toolDefaults = sc.dataFor('mycli', { defaultModel: 'gpt-3' });
+
+// Env-mapped runtime config
+const appData = await AppData.createAndInit<CliConfig>({
+  requiredKeys: ['githubToken'],
+  envMapping: {
+    githubToken: 'GITHUB_TOKEN',
+    model: 'hard:gpt-4',
+    cache: {
+      enabled: 'boolean:ENABLE_CACHE',
+      ttl: 'hard:3600',
+    },
+  },
+});
+
+// Persistent user-level cache
+const cache = new KeyValueStore({
+  typeArg: 'userHomeDir',
+  identityArg: 'mycli-cache',
+});
+
+// Check mandatory keys
+const missing = await appData.logMissingKeys();
+if (missing.length > 0) {
+  console.error('Missing config — set these env vars and retry.');
+  process.exit(1);
+}
+
+const store = await appData.getKvStore();
+const settings = await store.readAll();
+console.log(`Model: ${settings.model}, Cache: ${settings.cache.enabled}`);
+```

+# 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)
