+# Changelog
+
+## 2026-01-26 - 4.1.1 - fix(ts_web)
+fix web dashboard typings and update generated commit info
+
+- Updated generated commit info file ts_web/00_commitinfo_data.ts to version 4.1.0
+- Large changes applied to web/TS build files (net +529 additions, -399 deletions) — likely fixes and typing/refactor improvements in ts_web/dashboard
+- package.json remains at 4.1.0; recommend a patch bump to 4.1.1 for these fixes
+
+## 2026-01-26 - 4.1.0 - feat(task)
+add task labels and push-based task events
+
+- Introduce Task labels: Task accepts labels in constructor and exposes setLabel/getLabel/removeLabel/hasLabel; labels are included (shallow copy) in getMetadata().
+- Add push-based events: Task.eventSubject (rxjs Subject<ITaskEvent>) emits 'started','step','completed','failed' with timestamp; 'step' includes stepName and 'failed' includes error string.
+- Task now emits events during lifecycle: emits 'started' at run start, 'step' on notifyStep, and 'completed' or 'failed' when finished or errored. getMetadata() now includes labels.
+- TaskManager aggregates task events into taskSubject, subscribes on addTask and unsubscribes on removeTask/stop; includes helper methods getTasksByLabel and getTasksMetadataByLabel.
+- Public API updated: exported ITaskEvent and TTaskEventType in ts/index.ts and interfaces updated (labels in metadata, new event types).
+- Tests and docs: added test/test.12.labels-and-events.ts and updated readme.hints.md to document labels and push-based events.
+
+## 2026-01-25 - 4.0.0 - BREAKING CHANGE(taskbuffer)
+Change default Task error handling: trigger() now rejects when taskFunction throws; add catchErrors option (default false) to preserve previous swallow behavior; track errors (lastError, errorCount) and expose them in metadata; improve error propagation and logging across runners, chains, parallels and debounced tasks; add tests and documentation for new behavior.
+
+- Introduce catchErrors option on Task (default: false) — previously errors were swallowed by default
+- Tasks now set lastError and increment errorCount when failures occur; clearError() added to reset error state
+- getMetadata() now reports status 'failed' and includes lastError and errorCount
+- Task.run flow updated to reset error state at start, log errors, and either swallow or rethrow based on catchErrors
+- BufferRunner, TaskRunner, Taskchain, Taskparallel, TaskDebounced and TaskManager updated to handle errors, avoid hanging promises, and use logger instead of console
+- Added comprehensive tests (test/test.11.errorhandling.ts) and readme hints documenting the new error-handling behavior (v3.6.0+)
+- npmextra.json updated for @git.zone/cli and release registries
+
+## 2025-12-04 - 3.5.0 - feat(core)
+Add debounced tasks and step-based progress tracking; upgrade deps and improve dashboard and scheduling
+
+- Add TaskDebounced class to coalesce rapid triggers into a single execution (debounce behavior).
+- Introduce step tracking and progress reporting on Task via TaskStep, getProgress(), getStepsMetadata(), getMetadata(), resetSteps(), and completeAllSteps().
+- Enhance buffered execution flow: BufferRunner and CycleCounter improvements to better coordinate buffered runs and cycle promises.
+- Standardize concurrent runner naming (Taskparallel) and update related exports/usages (ts/index.ts, readme examples).
+- Enhance TaskManager scheduling/metadata: getScheduledTasks now returns schedule and nextRun, addExecuteRemoveTask collects execution report metadata and cleans up after execution, distributed coordination hooks retained.
+- Add/upgrade web dashboard UI, demos and refresh logic to surface task metadata, scheduled tasks and progress.
+- Bump runtime and dev dependencies (multiple @push.rocks packages and @git.zone tooling).
+- Update tests: reduce iteration threshold and tighten schedule interval in test/test.4.taskmanager.ts.
+- Remove several .serena memory files (project overview, style guides and suggested commands) as cleanup.
+
+## 2025-09-07 - 3.4.0 - feat(taskbuffer-dashboard)
+Add TaskBuffer dashboard web component, demo and browser tests; add HTML entry and update dependencies
+
+- Introduce a new web component taskbuffer-dashboard for real-time visualization of tasks and schedules (ts_web/taskbuffer-dashboard.ts).
+- Add a demo wrapper and interactive UI for the dashboard (ts_web/elements/taskbuffer-dashboard.demo.ts).
+- Provide web exports and typings for web usage (ts_web/index.ts) and include an HTML entry (html/index.html).
+- Add browser-oriented tests to validate metadata structures for the web component (test/test.10.webcomponent.browser.ts).
+- Bump package version to 3.3.0 in package.json as part of this change.
+- Update/add dependencies and devDependencies (@design.estate/dees-element added; smartlog, @git.zone/tsbuild and @git.zone/tstest bumped).
+
+## 2025-09-06 - 3.2.0 - feat(core)
+Add step-based progress tracking, task metadata and enhanced TaskManager scheduling/metadata APIs
+
+- Introduce TaskStep class for named, weighted steps with timing and status (pending|active|completed).
+- Add step-tracking to Task: notifyStep, getProgress, getStepsMetadata, getMetadata, resetSteps and internal step lifecycle handling.
+- Task now records runCount and lastRun; Task.run flow resets/cleans steps and aggregates progress.
+- TaskManager enhancements: schedule/deschedule improvements, performDistributedConsultation, and new metadata-focused APIs: getTaskMetadata, getAllTasksMetadata, getScheduledTasks, getNextScheduledRuns, addExecuteRemoveTask (exec + collect report).
+- Exports updated: TaskStep and related types exported from index, plus Task metadata interfaces.
+- Comprehensive README updates documenting step-based progress tracking, metadata, TaskManager and examples.
+- New/updated tests added for step behavior and metadata (test/test.9.steps.ts) and other TS additions.
+- Minor build/script change: build script updated to use 'tsbuild tsfolders'.
+
+## 2025-08-26 - 3.1.10 - fix(task)
+Implement core Task execution flow, buffering and lifecycle; update README with generics and buffer docs
+
+- Implement Task.runTask including preTask/afterTask chaining, touched-task cycle prevention and error handling.
+- Add Task helpers: extractTask, isTask, isTaskTouched and emptyTaskFunction (resolved promise).
+- Introduce task lifecycle coordination: finished promise, resolveFinished, and blockingTasks to await dependent tasks.
+- Support taskSetup/setupValue, execDelay handling, and wait-for-blocking-tasks before execution.
+- Wire up trigger() to choose buffered vs unbuffered execution (triggerBuffered / triggerUnBuffered) and integrate BufferRunner.
+- Improve logging and safer promise handling (caught errors are logged).
+- Update README with extended TypeScript generics examples and expanded buffer behavior and strategies documentation.
+
+## 2025-08-26 - 3.1.9 - fix(tests)
+Update CI workflows, fix tests and refresh README/package metadata
+
+- CI: switch Docker image to code.foss.global/host.today/ht-docker-node:npmci and adjust NPMCI_COMPUTED_REPOURL; replace npmci installer package name from @shipzone/npmci to @ship.zone/npmci in Gitea workflows
+- Tests: update test imports to use @git.zone/tstest/tapbundle and apply small formatting fixes to test files
+- Package metadata: update bugs URL and homepage to code.foss.global, add a pnpm.overrides placeholder in package.json
+- .gitignore: add AI/tooling directories (.claude, .serena) and reorganize custom section
+- Code style/TS fixes: minor formatting changes across ts sources (trailing commas, line breaks, consistent object/argument commas) and small API surface formatting fixes
+- Documentation: whitespace/formatting cleanups in README and add changelog entry for 3.1.8
+
+## 2025-08-26 - 3.1.8 - fix(tests)
+
+Update test runner and imports, refresh README and package metadata, add project tooling/config files

+- Replaced test imports from '@push.rocks/tapbundle' to '@git.zone/tstest/tapbundle' across test files
+- Updated test script in package.json to run tstest with --verbose --logfile --timeout 120
+- Bumped devDependency @git.zone/tstest to ^2.3.5 and adjusted package.json fields (typings, packageManager)
+- Expanded and rewrote README with detailed examples, API reference, and usage guidance
+- Refactored TaskManager tests (removed duplicate both-file and added consolidated test/test.4.taskmanager.ts)

+# Taskbuffer Hints
+
+## Error Handling (v3.6.0+)
+- `Task` now has `catchErrors` constructor option (default: `false`)
+- Default behavior: `trigger()` rejects when taskFunction throws (breaking change from pre-3.6)
+- Set `catchErrors: true` to swallow errors (old behavior) - returns `undefined` on error
+- Error state tracked via `lastError?: Error`, `errorCount: number`, `clearError()`
+- `getMetadata()` status uses all four values: `'idle'` | `'running'` | `'completed'` | `'failed'`
+- All peripheral classes (Taskchain, Taskparallel, TaskRunner, BufferRunner, TaskDebounced, TaskManager) have proper error propagation/handling
+- `console.log` calls replaced with `logger.log()` throughout
+
+## Breaking API Rename (TaskRunner)
+- `maxParrallelJobs` → `maxParallelJobs`
+- `qeuedTasks` → `queuedTasks`
+- JSDoc typos fixed: "qeue" → "queue", "wether" → "whether", "loose" → "lose"
+- The `setMaxParallelJobs()` parameter also renamed from `maxParrallelJobsArg` to `maxParallelJobsArg`
+
+## Error Context Improvements
+- **TaskChain**: Errors now wrap the original with context: chain name, failing task name, and task index. Original error preserved via `.cause`
+- **BufferRunner**: When `catchErrors: false`, buffered task errors now reject the trigger promise (via `CycleCounter.informOfCycleError`) instead of silently resolving with `undefined`
+- **TaskChain stubs completed**: `removeTask(task)` returns `boolean`, `shiftTask()` returns `Task | undefined`
+
+## Task Labels (v4.1.0+)
+- `Task` constructor accepts optional `labels?: Record<string, string>`
+- Helper methods: `setLabel(key, value)`, `getLabel(key)`, `removeLabel(key)`, `hasLabel(key, value?)`
+- `getMetadata()` includes `labels` (shallow copy)
+- `TaskManager.getTasksByLabel(key, value)` returns matching `Task[]`
+- `TaskManager.getTasksMetadataByLabel(key, value)` returns matching `ITaskMetadata[]`
+
+## Push-Based Events (v4.1.0+)
+- `Task.eventSubject`: rxjs `Subject<ITaskEvent>` emitting `'started'`, `'step'`, `'completed'`, `'failed'` events
+- `TaskManager.taskSubject`: aggregated `Subject<ITaskEvent>` from all added tasks
+- `TaskManager.removeTask(task)` unsubscribes and removes from map
+- `TaskManager.stop()` cleans up all event subscriptions
+- Exported types: `ITaskEvent`, `TTaskEventType`
+

+
+## 🎯 Core Concepts
+
+### Task Buffering — Intelligent Request Management
+
+Prevent overwhelming your system with rapid-fire requests:
+
+```typescript
+const apiTask = new Task({
+  name: 'APIRequest',
+  buffered: true,
+  bufferMax: 5, // Maximum 5 concurrent executions
+  execDelay: 100, // Minimum 100ms between executions
+  taskFunction: async (endpoint) => {
+    return await fetch(endpoint).then((r) => r.json());
+  },
+});
+
+// Rapid fire 100 calls — only bufferMax execute concurrently
+for (let i = 0; i < 100; i++) {
+  apiTask.trigger(`/api/data/${i}`);
+}
+```
+
+**Buffer Behavior:**
+
+- First `bufferMax` calls execute immediately
+- Additional calls are queued
+- When buffer is full, new calls overwrite the last queued item
+- Perfect for real-time data streams where only recent data matters
+
+### Task Chains — Sequential Workflows 🔗
+
+Build complex workflows with automatic data flow between tasks:
+
+```typescript
+import { Taskchain } from '@push.rocks/taskbuffer';
+
+const fetchTask = new Task({
+  name: 'Fetch',
+  taskFunction: async () => {
+    const res = await fetch('/api/data');
+    return res.json();
+  },
+});
+
+const transformTask = new Task({
+  name: 'Transform',
+  taskFunction: async (data) => {
+    return data.map((item) => ({ ...item, transformed: true }));
+  },
+});
+
+const saveTask = new Task({
+  name: 'Save',
+  taskFunction: async (transformedData) => {
+    await database.save(transformedData);
+    return transformedData.length;
+  },
+});
+
+const pipeline = new Taskchain({
+  name: 'DataPipeline',
+  taskArray: [fetchTask, transformTask, saveTask],
+});
+
+const savedCount = await pipeline.trigger();
+console.log(`Saved ${savedCount} items`);
+```
+
+Taskchain also supports dynamic mutation:
+
+```typescript
+pipeline.addTask(newTask); // Append to chain
+pipeline.removeTask(oldTask); // Remove by reference (returns boolean)
+pipeline.shiftTask(); // Remove & return first task
+```
+
+Error context is rich — a chain failure includes the chain name, failing task name, task index, and preserves the original error as `.cause`.
+
+### Parallel Execution — Concurrent Processing ⚡
+
+Execute multiple tasks simultaneously:
+
+```typescript
+import { Taskparallel } from '@push.rocks/taskbuffer';
+
+const parallel = new Taskparallel({
+  taskArray: [emailTask, smsTask, pushNotificationTask, webhookTask],
+});
+
+await parallel.trigger(notificationData);
+```
+
+### Debounced Tasks — Smart Trigger Coalescing 🕐
+
+Coalesce rapid triggers into a single execution after a quiet period:
+
+```typescript
+import { TaskDebounced } from '@push.rocks/taskbuffer';
+
+const searchTask = new TaskDebounced({
+  name: 'Search',
+  debounceTimeInMillis: 300,
+  taskFunction: async (query) => {
+    return await searchAPI(query);
+  },
+});
+
+// Rapid calls — only the last triggers after 300ms of quiet
+searchTask.trigger('h');
+searchTask.trigger('he');
+searchTask.trigger('hel');
+searchTask.trigger('hello'); // ← this one fires
+```
+
+### TaskOnce — Single-Execution Guard
+
+Ensure a task only runs once, regardless of how many times it's triggered:
+
+```typescript
+import { TaskOnce } from '@push.rocks/taskbuffer';
+
+const initTask = new TaskOnce({
+  name: 'Init',
+  taskFunction: async () => {
+    await setupDatabase();
+    console.log('Initialized!');
+  },
+});
+
+await initTask.trigger(); // Runs
+await initTask.trigger(); // No-op
+await initTask.trigger(); // No-op
+console.log(initTask.hasTriggered); // true
+```
+
+### TaskRunner — Managed Queue with Concurrency Control
+
+Process a queue of tasks with a configurable parallelism limit:
+
+```typescript
+import { TaskRunner } from '@push.rocks/taskbuffer';
+
+const runner = new TaskRunner();
+runner.setMaxParallelJobs(3); // Run up to 3 tasks concurrently
+
+await runner.start();
+
+runner.addTask(taskA);
+runner.addTask(taskB);
+runner.addTask(taskC);
+runner.addTask(taskD); // Queued until a slot opens
+
+// When done:
+await runner.stop();
+```
+
+## 🏷️ Labels — Multi-Tenant Task Filtering
+
+Attach arbitrary key-value labels to any task for filtering, grouping, or multi-tenant isolation:
+
+```typescript
+const task = new Task({
+  name: 'ProcessOrder',
+  labels: { userId: 'u-42', tenantId: 'acme-corp', priority: 'high' },
+  taskFunction: async (order) => {
+    /* ... */
+  },
+});
+
+// Manipulate labels at runtime
+task.setLabel('region', 'eu-west');
+task.getLabel('userId'); // 'u-42'
+task.hasLabel('tenantId', 'acme-corp'); // true
+task.removeLabel('priority'); // true
+
+// Labels are included in metadata snapshots
+const meta = task.getMetadata();
+console.log(meta.labels); // { userId: 'u-42', tenantId: 'acme-corp', region: 'eu-west' }
+```
+
+### Filtering Tasks by Label in TaskManager
+
+```typescript
+const manager = new TaskManager();
+manager.addTask(orderTask1); // labels: { tenantId: 'acme' }
+manager.addTask(orderTask2); // labels: { tenantId: 'globex' }
+manager.addTask(orderTask3); // labels: { tenantId: 'acme' }
+
+const acmeTasks = manager.getTasksByLabel('tenantId', 'acme');
+// → [orderTask1, orderTask3]
+
+const acmeMetadata = manager.getTasksMetadataByLabel('tenantId', 'acme');
+// → [ITaskMetadata, ITaskMetadata]
+```
+
+## 📡 Push-Based Events — Real-Time Task Lifecycle
+
+Every `Task` exposes an rxjs `Subject<ITaskEvent>` that emits events as the task progresses through its lifecycle:
+
+```typescript
+import type { ITaskEvent } from '@push.rocks/taskbuffer';
+
+const task = new Task({
+  name: 'DataSync',
+  steps: [
+    { name: 'fetch', description: 'Fetching data', percentage: 50 },
+    { name: 'save', description: 'Saving data', percentage: 50 },
+  ] as const,
+  taskFunction: async () => {
+    task.notifyStep('fetch');
+    const data = await fetchData();
+    task.notifyStep('save');
+    await saveData(data);
+  },
+});
+
+// Subscribe to individual task events
+task.eventSubject.subscribe((event: ITaskEvent) => {
+  console.log(`[${event.type}] ${event.task.name} @ ${new Date(event.timestamp).toISOString()}`);
+  if (event.type === 'step') console.log(`  Step: ${event.stepName}`);
+  if (event.type === 'failed') console.log(`  Error: ${event.error}`);
+});
+
+await task.trigger();
+// [started] DataSync @ 2025-01-26T...
+// [step] DataSync @ 2025-01-26T...
+//   Step: fetch
+// [step] DataSync @ 2025-01-26T...
+//   Step: save
+// [completed] DataSync @ 2025-01-26T...
+```
+
+### Event Types
+
+| Type | When | Extra Fields |
+| --- | --- | --- |
+| `'started'` | Task begins execution | — |
+| `'step'` | `notifyStep()` is called | `stepName` |
+| `'completed'` | Task finishes successfully | — |
+| `'failed'` | Task throws an error | `error` (message string) |
+
+Every event includes a full `ITaskMetadata` snapshot (including labels) at the time of emission.
+
+### Aggregated Events on TaskManager
+
+`TaskManager` automatically aggregates events from all added tasks into a single `taskSubject`:
+
+```typescript
+const manager = new TaskManager();
+manager.addTask(syncTask);
+manager.addTask(reportTask);
+manager.addTask(cleanupTask);
+
+// Single subscription for ALL task events
+manager.taskSubject.subscribe((event) => {
+  sendToMonitoringDashboard(event);
+});
+
+// Events stop flowing for a task after removal
+manager.removeTask(syncTask);
+```
+
+`manager.stop()` automatically cleans up all event subscriptions.
+
+## 🛡️ Error Handling
+
+By default, `trigger()` **rejects** when the task function throws — errors propagate naturally:
+
+```typescript
+const task = new Task({
+  name: 'RiskyOp',
+  taskFunction: async () => {
+    throw new Error('something broke');
+  },
+});
+
+try {
+  await task.trigger();
+} catch (err) {
+  console.error(err.message); // "something broke"
+}
+```
+
+### Swallowing Errors with `catchErrors`
+
+Set `catchErrors: true` to swallow errors and return `undefined` instead of rejecting:
+
+```typescript
+const task = new Task({
+  name: 'BestEffort',
+  catchErrors: true,
+  taskFunction: async () => {
+    throw new Error('non-critical');
+  },
+});
+
+const result = await task.trigger(); // undefined (no throw)
+```
+
+### Error State Tracking
+
+Regardless of `catchErrors`, the task tracks errors:
+
+```typescript
+console.log(task.lastError); // Error object (or undefined)
+console.log(task.errorCount); // Number of failures across all runs
+console.log(task.getMetadata().status); // 'failed'
+
+task.clearError(); // Resets lastError to undefined (errorCount stays)
+```
+
+On a subsequent successful run, `lastError` is automatically cleared.
+
+## 📋 TaskManager — Centralized Orchestration
+
+```typescript
+const manager = new TaskManager();
+
+// Add tasks
+manager.addTask(dataProcessor);
+manager.addTask(deployTask);
+
+// Schedule with cron expressions
+manager.addAndScheduleTask(backupTask, '0 2 * * *'); // Daily at 2 AM
+manager.addAndScheduleTask(healthCheck, '*/5 * * * *'); // Every 5 minutes
+
+// Query metadata
+const meta = manager.getTaskMetadata('Deploy');
+console.log(meta);
+// {
+//   name: 'Deploy',
+//   status: 'completed',
+//   steps: [...],
+//   currentProgress: 100,
+//   runCount: 3,
+//   labels: { env: 'production' },
+//   lastError: undefined,
+//   errorCount: 0,
+//   ...
+// }
+
+// All tasks at once
+const allMeta = manager.getAllTasksMetadata();
+
+// Scheduled task info
+const scheduled = manager.getScheduledTasks();
+const nextRuns = manager.getNextScheduledRuns(5);
+
+// Trigger by name
+await manager.triggerTaskByName('Deploy');
+
+// One-shot: add, execute, collect report, remove
+const report = await manager.addExecuteRemoveTask(temporaryTask);
+console.log(report);
+// {
+//   taskName: 'TempTask',
+//   startTime: 1706284800000,
+//   endTime: 1706284801523,
+//   duration: 1523,
+//   steps: [...],
+//   stepsCompleted: ['step1', 'step2'],
+//   progress: 100,
+//   result: any
+// }
+
+// Lifecycle
+await manager.start(); // Starts cron scheduling + distributed coordinator
+await manager.stop(); // Stops scheduling, cleans up event subscriptions
+```
+
+### Remove Tasks
+
+```typescript
+manager.removeTask(task); // Removes from map and unsubscribes event forwarding
+manager.descheduleTaskByName('Deploy'); // Remove cron schedule only
+```
+
+## 🎨 Web Component Dashboard
+
+Visualize your tasks in real-time with the included Lit-based web component:
+
+```html
+<script type="module">
+  import { TaskManager } from '@push.rocks/taskbuffer';
+  import '@push.rocks/taskbuffer/dist_ts_web/taskbuffer-dashboard.js';
+
+  const manager = new TaskManager();
+  // ... add and schedule tasks ...
+
+  const dashboard = document.querySelector('taskbuffer-dashboard');
+  dashboard.taskManager = manager;
+  dashboard.refreshInterval = 500; // Poll every 500ms
+</script>
+
+<taskbuffer-dashboard></taskbuffer-dashboard>
+```
+
+The dashboard provides:
+
+- 📊 Real-time progress bars with step indicators
+- 📈 Task execution history and metadata
+- ⏰ Scheduled task information with next-run times
+- 🌓 Light/dark theme support
+
+## 🌐 Distributed Coordination
+
+For multi-instance deployments, extend `AbstractDistributedCoordinator` to prevent duplicate task execution:
+
+```typescript
+import { TaskManager, distributedCoordination } from '@push.rocks/taskbuffer';
+
+class RedisCoordinator extends distributedCoordination.AbstractDistributedCoordinator {
+  async fireDistributedTaskRequest(request) {
+    // Implement leader election / distributed lock via Redis
+    return { shouldTrigger: true, considered: true, rank: 1, reason: 'elected', ...request };
+  }
+  async updateDistributedTaskRequest(request) {
+    /* update status */
+  }
+  async start() {
+    /* connect */
+  }
+  async stop() {
+    /* disconnect */
+  }
+}
+
+const manager = new TaskManager({
+  distributedCoordinator: new RedisCoordinator(),
+});
+```
+
+When a distributed coordinator is configured, scheduled tasks consult it before executing — only the elected instance runs the task.
+
+## 🧩 Advanced Patterns
+
+### Pre-Task & After-Task Hooks
+
+Run setup/teardown tasks automatically:
+
+```typescript
+const mainTask = new Task({
+  name: 'MainWork',
+  preTask: new Task({
+    name: 'Setup',
+    taskFunction: async () => {
+      console.log('Setting up...');
+    },
+  }),
+  afterTask: new Task({
+    name: 'Cleanup',
+    taskFunction: async () => {
+      console.log('Cleaning up...');
+    },
+  }),
+  taskFunction: async () => {
+    console.log('Doing work...');
+    return 'done';
+  },
+});
+
+await mainTask.trigger();
+// Setting up... → Doing work... → Cleaning up...
+```
+
+### One-Time Setup Functions
+
+Run an expensive initialization exactly once, before the first execution:
+
+```typescript
+const task = new Task({
+  name: 'DBQuery',
+  taskSetup: async () => {
+    const pool = await createConnectionPool();
+    return pool; // This becomes `setupValue`
+  },
+  taskFunction: async (input, pool) => {
+    return await pool.query(input);
+  },
+});
+
+await task.trigger('SELECT * FROM users'); // Setup runs here
+await task.trigger('SELECT * FROM orders'); // Setup skipped, pool reused
+```
+
+### Blocking Tasks
+
+Make one task wait for another to finish before executing:
+
+```typescript
+const initTask = new Task({
+  name: 'Init',
+  taskFunction: async () => {
+    await initializeSystem();
+  },
+});
+
+const workerTask = new Task({
+  name: 'Worker',
+  taskFunction: async () => {
+    await doWork();
+  },
+});
+
+workerTask.blockingTasks.push(initTask);
+
+// Triggering worker will automatically wait for init to complete
+initTask.trigger();
+workerTask.trigger(); // Waits until initTask.finished resolves
+```
+
+### Database Migration Pipeline
+
+```typescript
+const migration = new Taskchain({
+  name: 'DatabaseMigration',
+  taskArray: [backupTask, validateSchemaTask, runMigrationsTask, verifyIntegrityTask],
+});
+
+try {
+  await migration.trigger();
+  console.log('Migration successful!');
+} catch (error) {
+  // error includes chain name, failing task name, index, and original cause
+  console.error(error.message);
+  await rollbackTask.trigger();
+}
+```
+
+### Multi-Tenant SaaS Monitoring
+
+Combine labels + events for a real-time multi-tenant dashboard:
+
+```typescript
+const manager = new TaskManager();
+
+// Create tenant-scoped tasks
+function createTenantTask(tenantId: string, taskName: string, fn: () => Promise<any>) {
+  const task = new Task({
+    name: `${tenantId}:${taskName}`,
+    labels: { tenantId },
+    taskFunction: fn,
+  });
+  manager.addTask(task);
+  return task;
+}
+
+createTenantTask('acme', 'sync', async () => syncData('acme'));
+createTenantTask('globex', 'sync', async () => syncData('globex'));
+
+// Stream events to tenant-specific WebSocket channels
+manager.taskSubject.subscribe((event) => {
+  const tenantId = event.task.labels?.tenantId;
+  if (tenantId) {
+    wss.broadcast(tenantId, JSON.stringify(event));
+  }
+});
+
+// Query tasks for a specific tenant
+const acmeTasks = manager.getTasksMetadataByLabel('tenantId', 'acme');
+```
