+# Changelog
+
+## 2026-03-24 - 6.1.0 - feat(docs)
+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
+- Added .claude/settings.local.json to provide local Claude permissions and tooling allowances for development/CI helpers
+
+## 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.
+- Introduced .claude/settings.local.json with updated permissions for local development.
+
+## 2025-08-15 - 5.3.0 - feat(AppData)
+Refactor AppData class for declarative env mapping and enhanced static helpers
+
+- Introduced a singleton Qenv provider to optimize environment variable resolution.
+- Centralized type conversion logic with utility functions for boolean, JSON, base64, number, and string conversions.
+- Replaced complex switch statements with a composable, declarative mapping pipeline for processing envMapping.
+- Enhanced logging during AppData initialization to clearly report key processing and overwrite operations.
+- Added new static helper methods for environment variable access (valueAsBoolean, valueAsJson, valueAsBase64, valueAsString, valueAsNumber).
+- Fixed boolean conversion issues and ensured backward compatibility with the deprecated 'ephermal' option.
+
+## 2025-08-15 - 5.2.0 - feat(AppData)
+Major refactoring of AppData class for improved elegance and maintainability
+
+- **New Features:**
+  - Added static helper methods for direct environment variable access:
+    - `AppData.valueAsBoolean()` - Convert env vars to boolean
+    - `AppData.valueAsJson()` - Parse env vars as JSON
+    - `AppData.valueAsBase64()` - Decode base64 env vars
+    - `AppData.valueAsString()` - Get env vars as string
+    - `AppData.valueAsNumber()` - Parse env vars as number
+  - Enhanced logging for AppData initialization and key processing:
+    - Shows which storage type is being used (custom, ephemeral, auto-selected)
+    - Logs each key being processed with its spec type
+    - Reports success/failure for each key with type information
+    - Provides summary statistics of processed keys
+
+- **Architecture Improvements:**
+  - Replaced 100+ line switch statement with declarative pipeline architecture
+  - Introduced centralized type converters and transform registry
+  - Implemented composable transform pipeline: `parseMappingSpec()` → `resolveSource()` → `applyTransforms()`
+  - Added singleton Qenv provider to reduce allocations
+  - Reduced code complexity by ~70% while maintaining 100% backward compatibility
+
+- **Bug Fixes:**
+  - Fixed boolean conversion to properly handle both string and boolean inputs
+  - Added `ephemeral` option (correctly spelled) while maintaining backward compatibility with deprecated `ephermal`
+
+- **Performance:**
+  - Optimized environment variable resolution with shared Qenv instance
+  - Reduced object allocations in static helpers

-## Usage
+## Install 📦
 
-Use TypeScript for best in class instellisense.
+```bash
+npm install @push.rocks/smartconfig --save
+# or
+pnpm add @push.rocks/smartconfig
+```
 
-## Using npmextra for managing toolconfigs
+## Quick Start ⚡
 
-The main purpose of npmextra is to configure different tools using one npmextra.json. This way complex setups avoid additional complexity caused by too many configuration files.
+```typescript
+import { Smartconfig, AppData, KeyValueStore } from '@push.rocks/smartconfig';
 
-npmextra.json
+// 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());
+```
+
+## 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
+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,
+});
+```
+
+**`.smartconfig.json`** example:
 
 ```json
 {
-  "sometool": {
+  "prettier": {
-    "defaultKey1": "awesomeValueFromConfig"
+    "semi": true,
+    "printWidth": 120
+  },
+  "eslint": {
+    "extends": "@company/eslint-config"
   }
 }
 ```
 
-```typescript
+Values from the file override the defaults you pass in. Missing keys fall back to your defaults.
-import { Npmextra } from 'npmextra';
 
-let myNpmExtra = new Npmextra('my/path/to/cwd'); // cwd argument is optional
+**Properties:**
-mergedData = myNpmExtra.dataFor('sometool', {
+- `smartconfigJsonExists: boolean` — whether `.smartconfig.json` was found
-  // gets merged with whatever is in the configfile
+- `smartconfigJsonData: any` — the parsed JSON contents
-  defaultKey1: 'defaultValue1', // so this will get overwritten with "awesomeValueFromConfig"
+
-  defaultKey2: 'defaultValue2', // this one will pass through unaltered
+**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 { KeyValueStore } from '@push.rocks/smartconfig';
+
+interface Settings {
+  username: string;
+  theme: 'light' | 'dark';
+}
+
+// Store in ~/.smartconfig/kv/
+const kv = new KeyValueStore<Settings>({
+  typeArg: 'userHomeDir',
+  identityArg: 'myApp',
+  mandatoryKeys: ['username'],
 });
+
+await kv.writeKey('username', 'jane');
+await kv.writeKey('theme', 'dark');
+
+const user = await kv.readKey('username'); // 'jane'
+const all = await kv.readAll();            // { username: 'jane', theme: 'dark' }
+
+// React to changes
+kv.changeSubject.subscribe((data) => console.log('changed:', data));
 ```
 
-### Tools that already use the config feature of npmextra
+**Storage types:**
 
-- [npmts](https://www.npmjs.com/package/npmts)
+| `typeArg` | Where it goes | Use case |
-- [npmci](https://www.npmjs.com/package/npmci)
+|-----------|--------------|----------|
-- [npmdocker](https://www.npmjs.com/package/npmdocker)
+| `'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 |

+```typescript
+import { AppData } from '@push.rocks/smartconfig';
+
+interface Config {
+  apiUrl: string;
+  apiKey: string;
+  features: {
+    analytics: boolean;
+    payment: boolean;
+  };
+  redis: {
+    host: string;
+    password: string;
+  };
+}
+
+const appData = await AppData.createAndInit<Config>({
+  requiredKeys: ['apiKey'],
+  envMapping: {
+    apiUrl: 'API_URL',                        // plain env var
+    apiKey: 'hard:dev-key-123',               // hardcoded fallback
+    features: {
+      analytics: 'boolean:ENABLE_ANALYTICS',  // converts "true"/"false" → boolean
+      payment: 'hard_boolean:true',           // hardcoded boolean
+    },
+    redis: {
+      host: 'REDIS_HOST',
+      password: 'base64:REDIS_PASSWORD_B64',  // base64-decode at load time
+    },
+  },
+  overwriteObject: {
+    apiUrl: 'http://localhost:3000',           // force override after env mapping
+  },
+});
+
+const store = await appData.getKvStore();
+const url = await store.readKey('apiUrl');
+```
+
+#### Mapping Prefixes
+
+| 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"` |
+
+Suffix detection also works: a mapping ending in `_JSON` or `_BASE64` triggers the corresponding transform automatically.
+
+#### 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)
