+# Changelog
+
+## 2026-02-15 - 6.0.0 - BREAKING CHANGE(constraints)
+make TaskConstraintGroup constraint matcher input-aware and add shouldExecute pre-execution hook
+
+- Rename ITaskConstraintGroupOptions.constraintKeyForTask -> constraintKeyForExecution(task, input?) and update TaskConstraintGroup.getConstraintKey signature
+- Add optional shouldExecute(task, input?) hook; TaskManager checks shouldExecute before immediate runs, after acquiring slots, and when draining the constraint queue (queued tasks are skipped when shouldExecute returns false)
+- Export ITaskExecution type and store constraintKeys on queued entries (IConstrainedTaskEntry.constraintKeys)
+- Documentation and tests updated to demonstrate input-aware constraint keys and shouldExecute pruning
+
+## 2026-02-15 - 5.0.1 - fix(tests)
+add and tighten constraint-related tests covering return values, error propagation, concurrency, cooldown timing, and constraint removal
+
+- Tightened cooldown timing assertion from >=100ms to >=250ms to reflect 300ms cooldown with 50ms tolerance.
+- Added tests for queued task return values, error propagation when catchErrors is false, and error swallowing behavior when catchErrors is true.
+- Added concurrency and cooldown interaction tests to ensure maxConcurrent is respected and batch timing is correct.
+- Added test verifying removing a constraint group unblocks queued tasks and drain behavior completes correctly.
+
+## 2026-02-15 - 5.0.0 - BREAKING CHANGE(taskbuffer)
+Introduce constraint-based concurrency with TaskConstraintGroup and TaskManager integration; remove legacy TaskRunner and several Task APIs (breaking); add typed Task.data and update exports and tests.
+
+- Add TaskConstraintGroup class with per-key maxConcurrent, cooldownMs, and helper methods (canRun, acquireSlot, releaseSlot, getCooldownRemaining, getRunningCount, reset).
+- Task generic signature extended to Task<T, TSteps, TData> and a new typed data property (data) with default {}.
+- TaskManager now supports addConstraintGroup/removeConstraintGroup, triggerTaskConstrained, queues blocked tasks, drains queue with cooldown timers, and routes triggerTask/triggerTaskByName through the constraint system.
+- Removed TaskRunner, plus Task APIs: blockingTasks, execDelay, finished promise and associated behavior have been removed (breaking changes).
+- Exports and interfaces updated: TaskConstraintGroup and ITaskConstraintGroupOptions added; TaskRunner removed from public API.
+- Updated README and added comprehensive tests for constraint behavior; adjusted other tests to remove TaskRunner usage and reflect new APIs.
+
+## 2026-02-15 - 4.2.1 - fix(deps)
+bump @push.rocks/smartlog and @types/node; update dependency list version and license link in docs
+
+- package.json: update @push.rocks/smartlog from ^3.1.10 to ^3.1.11
+- package.json: update @types/node from ^25.1.0 to ^25.2.3
+- readme.hints.md: update 'Dependencies (as of v4.1.1)' to 'Dependencies (as of v4.2.0)' and reflect bumped dependency versions
+- readme.md: change license link text to '[LICENSE](./license.md)'
+
+## 2026-01-29 - 4.2.0 - feat(ts_web)
+support TC39 'accessor' decorators for web components; bump dependencies and devDependencies; rename browser tests to .chromium.ts; move LICENSE to license.md and update readme
+
+- Convert web component class fields to use the TC39 'accessor' keyword in ts_web/taskbuffer-dashboard.ts to be compatible with @design.estate/dees-element v2.1.6
+- Bump @design.estate/dees-element to ^2.1.6 and update devDependencies (@git.zone/tsbuild, @git.zone/tsbundle, @git.zone/tsrun, @git.zone/tstest, @types/node) to newer versions
+- Replace test/test.10.webcomponent.browser.ts with test/test.10.webcomponent.chromium.ts and update testing guidance in readme.hints.md to prefer .chromium.ts
+- Move LICENSE file content to license.md and update readme.md to reference the new license file
+- Small test cleanups: remove obsolete tslint:disable comments
+
+## 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)
+- Added development/project tooling and metadata files (.claude settings, .serena project/memories) to aid local development and CI

+# Taskbuffer Hints
+
+## Task Constraint System (v5.0.0+) — Breaking Changes
+- **`TaskRunner` removed** — replaced by `TaskManager` + `TaskConstraintGroup`
+- **`blockingTasks` removed** from `Task` — use `TaskConstraintGroup` with `maxConcurrent: 1`
+- **`execDelay` removed** from `Task` — use `TaskConstraintGroup` with `cooldownMs`
+- **`finished` promise removed** from `Task` — no longer needed
+- **`Task` generic signature**: `Task<T, TSteps, TData>` (3rd param added for typed data)
+
+### Task.data
+- `Task` constructor accepts optional `data?: TData` (defaults to `{}`)
+- Typed data bag accessible as `task.data`
+
+### TaskConstraintGroup
+- `new TaskConstraintGroup<TData>({ name, constraintKeyForExecution, maxConcurrent?, cooldownMs?, shouldExecute? })`
+- `constraintKeyForExecution(task, input?)` returns a string key (constraint applies) or `null` (skip). Receives both task and runtime input.
+- `shouldExecute(task, input?)` — optional pre-execution check. Returns `false` to skip (deferred resolves `undefined`). Can be async.
+- `maxConcurrent` (default: `Infinity`) — max concurrent tasks per key
+- `cooldownMs` (default: `0`) — minimum ms gap between completions per key
+- Methods: `getConstraintKey(task, input?)`, `checkShouldExecute(task, input?)`, `canRun(key)`, `acquireSlot(key)`, `releaseSlot(key)`, `getCooldownRemaining(key)`, `getRunningCount(key)`, `reset()`
+- `ITaskExecution<TData>` type exported from index — `{ task, input }` tuple
+
+### TaskManager Constraint Integration
+- `manager.addConstraintGroup(group)` / `manager.removeConstraintGroup(name)`
+- `triggerTaskByName()`, `triggerTask()`, `addExecuteRemoveTask()`, cron callbacks all route through `triggerTaskConstrained()`
+- `triggerTaskConstrained(task, input?)` — evaluates constraints, queues if blocked, drains after completion
+- Cooldown-blocked entries auto-drain via timer
+
+### Exported from index.ts
+- `TaskConstraintGroup` class
+- `ITaskConstraintGroupOptions` type
+
+## 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, BufferRunner, TaskDebounced, TaskManager) have proper error propagation/handling
+- `console.log` calls replaced with `logger.log()` throughout
+
+## 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`
+
+## Project Structure
+- Source in `ts/`, web components in `ts_web/`
+- Tests in `test/` - naming: `*.node.ts`, `*.chromium.ts` (preferred), `*.both.ts`
+  - Note: `*.browser.ts` is deprecated, use `*.chromium.ts` for browser tests
+- Logger: `ts/taskbuffer.logging.ts` exports `logger` (ConsoleLog from smartlog)
+- Build: `pnpm build` (tsbuild tsfolders)
+- Test: `pnpm test` or `tstest test/test.XX.name.ts --verbose`
+
+## Web Components (ts_web/)
+- Uses `@design.estate/dees-element` with TC39 decorators
+- Decorators require the `accessor` keyword:
+  ```typescript
+  @property({ type: String })
+  accessor myProp = 'default';
+
+  @state()
+  accessor count = 0;
+  ```
+
+## Dependencies (as of v4.2.0)
+- `@design.estate/dees-element` ^2.1.6 - TC39 decorators with `accessor` keyword
+- `@push.rocks/lik` ^6.2.2 - Data structures
+- `@push.rocks/smartdelay` ^3.0.5 - Delay utilities
+- `@push.rocks/smartlog` ^3.1.11 - Logging
+- `@push.rocks/smartpromise` ^4.2.3 - Promise utilities
+- `@push.rocks/smartrx` ^3.0.10 - RxJS wrapper
+- `@push.rocks/smarttime` ^4.1.1 - Time/cron utilities
+- `@push.rocks/smartunique` ^3.0.9 - Unique ID generation
+- `@git.zone/tsbuild` ^4.1.2 - Build tool
+- `@git.zone/tsbundle` ^2.8.3 - Bundler (for browser tests)
+- `@git.zone/tsrun` ^2.0.1 - TypeScript runner
+- `@git.zone/tstest` ^3.1.8 - Test runner (supports `.chromium.ts` files)
+- `@types/node` ^25.2.3 - Node.js type definitions
