The complete package includes:

• x64 and x86 ATC executables;
• x64 and x86 launchers;
• application icons, PDF/update icons and package resources;
• script examples;
• To solve examples;
• user functions;
• string examples;
• English and Portuguese documentation in Markdown, PDF and DOCX where available;
• professional RELEASE_HISTORY.txt with all 66 historical release entries preserved;
• GPL-3.0 license file;
• README, VERSION, SOURCE and checksums files.

Known limitations

• ATC is not a full general-purpose CAS.
• Some symbolic behavior exists only where explicitly implemented and tested.
• Windows 11 console rendering still benefits from manual validation across console hosts.
• Some external UI flows and long-running interactive tools remain manual validation targets.
• GitHub Actions remains inactive. The proposed workflow is documented, but the legacy v141_xp toolset may require a self-hosted Windows runner.

Validation summary

• x64 Release: 0 warnings, 0 errors.
• x86 Release: 0 warnings, 0 errors.
• Full regression x64: 377 passed, 0 failed.
• Matrix parallelism x64/x86: 10 passed, 0 failed.
• Script benchmark x64: 4 passed, 0 failed.
• Complete package validation: passed.
• Complete package ZIP extraction: passed.
• Complete package smoke checks: x64 and x86 2+2+2 returned #0=6.
