# Changelog

## 0.2.0 — unreleased clean candidate

- Present the project as NexCUA and identify the released component as NorthCUA Harness.
  Retain the `northcua` package/CLI names and restore the complete NexCUA logo.

- Desktop and Web agents, artifact/live evaluators and reliable batch execution form the supported scope.
- Removed driver/PiP, data/training pipelines, environment generation, warm reuse and dated operator scripts.
- Added durable replaceable task working memory and a shared Web evaluation lifecycle before browser release.
- Count Web Set-of-Mark images within the total image budget; expose consistent evaluator budgets.
- Package portable configs; pin public NexAU in wheel metadata; declare the device's root bridge dependency.
- Add a public OSWorld task adapter and rebuildable Desktop/Web template definitions.
- Redesign docs around installation, modes, paper mechanisms, tests and evidence-based release gates.

- Reserve WebSocket sessions before acceptance; stop task admission before draining resources.
- Serialize local Desktop tasks across sessions, preserve logical session IDs, and return explicit failure terminals.
- Propagate remote browser cleanup failures and release per-session adapter caches.
- Remove duplicate CLI registries/visual planner and obsolete configuration scaffolding.
- Ship NOTICE in all four wheels; extend candidate-branch CI, complete scoped type checks and collect installed-task reports.
- Add a bilingual README, illustrated system tour, contributor templates and the 2026-10-03 paper snapshot.
- Keep one Desktop tool-returned-image path; remove alternate observation policies,
  projection factories, configurable probe chains, the duplicate collector and generic image allocation.
- Preserve current grounding after a text-only note and reject obsolete observation configuration fields.
- Add a repository-distributed operator skill, from-zero guides and model connection
  templates that initialize both agents with one command.
- Ship a reusable, credential-free tutorial with real NexAU, browser/native tools,
  task-specific receipts and live Web evaluation through a scripted model endpoint.
- Support small local Web batches through the existing controller and scheduler,
  including bounded workers, durable resume, drain and verified process cleanup.
- Preserve macOS modifier flags and Return input through Quartz; guard native
  tutorial focus against other applications while ignoring the system cursor overlay.
- Constrain NexAU's compatible AG-UI protocol dependency in the local extra so
  fresh wheel installations match the tested runtime.

This is a breaking release. Start new run directories; do not resume an old private run in place.
