Renames Webwright to CUAWright and adds desktop support. Browser and desktop agents now use a unified structure under src/cuawright; the existing browser implementation remains under src/webwright for backward compatibility.

Changes

• Organize the canonical runtime into agents, config, environments, models, run, tools, and utils, with browser and desktop adapters.
• Share loop scheduling, model-call accounting, stateless Responses options, and image encoding. Preserve browser reflection gates, trajectory persistence, and compaction behavior; preserve desktop explicit submission, incomplete-command rejection, sanitized retries, and multi-phase budgets.
• Add cuawright web and cuawright desktop. Keep cuawright-web, cuawright-desktop, and the retained webwright command and Python imports.
• Keep OSWorld source validation, compatibility patches, setup, and official evaluation under run/benchmarks/osworld; keep the guest bridge under environments/desktop.
• Keep Skill Factory a separately installed optional cuawright-skill-factory distribution. Canonical addon imports are cuawright.skill_factory and cuawright.tools.skill_use; legacy addon imports resolve to the same modules when installed.
• Include unified core provenance in wheels and source archives. Keep the MIT browser license and imported desktop Apache-2.0 attribution.
• Update README migration/news, project map, desktop setup, skills, architecture documentation, packaging tests, and CI.
• Exclude private gateway configuration. Keep user-supplied endpoint URLs, credential paths, and proxy configuration paths out of public settings, with regression coverage.

Lines of code

Physical Python lines including blank lines and comments; YAML, documentation, assets, and the build hook excluded:

Area	Lines	Python files
Unified src/cuawright runtime	8,336	51
Retained src/webwright runtime	6,291	30
Base wheel total	14,627	81
Optional Skill Factory, including examples	3,808	21
Tests, including desktop release tests	4,482	26

These are final-tree counts, not lines newly added. Retaining the browser implementation increases packaged size for backward compatibility. Folder consolidation does not remove browser tools. The optional addon includes 1,509 lines of examples.

Validation

• Full source suite: 276 passed, including browser parity for submission, limits, format recovery, reflection gating, and compaction.
• Desktop suite against the installed wheel: 90 passed.
• Built core and optional-addon wheels and source archives.
• Clean wheel installation verified unified and legacy browser commands, desktop help, addon installation, legacy addon imports, provenance with the addon installed, and addon removal.
• Compile, whitespace, and desktop public-URL/credential checks passed.

Scope and limitations

Desktop support requires Python 3.12+ and externally provisioned OSWorld-V2 v2026.08.08, Ubuntu VM, Docker, tasks, assets, websites, and credentials. No live or paid OSWorld evaluation was run. Browser and desktop transports, messages, prompts, completion gates, and compaction policy retain their separate contracts. Repository URLs continue to reference the existing Webwright GitHub repository.
