    Save As destination collisions now explain that existing files are protected
    and offer clear recovery: choose a fresh source directory, or use Save All at
    the current entry. Genuine observed external edits keep their distinct
    external-change diagnosis. This preview includes the prior compact diagram
    controls and contextual Help; model/source/history semantics and REST contracts
    are unchanged.

    Download the Windows x86-64 Studio ZIP and checksum, verify SHA256 and extract
    the whole folder. Launch arcadia-studio.exe, keeping libunwind.dll beside both
    executables. Read START-HERE.txt and the attached VALIDATION.md. Copy a complete
    example before editing; Save As copies model source with existing include paths,
    so companion/external artifacts need separate copying. The optional REST server,
    examples, offline guide and notices are included.

    Desktop source 0e83157e09; packaged documentation
    ef28f1784e. The server is the unchanged released
    715 artifact with recovered original build provenance and fresh tests of this
    bundle's selected runtime. Both binaries use the dev/unoptimized profile;
    packaging did not rebuild them.

    Verified: 29 targeted desktop save checks, formatting, strict Clippy and matching
    GUI build; exact archive/extraction/notice/documentation identities; fresh
    independent source/artifact/native/REST/claims review. Two actual extracted
    desktop sessions exercise Apply, accurate refusal and recovery, genuine external
    edit protection, fresh Save As, reopen and no-op Save All. Complete 37-file byte
    oracles and full 30-source-file parsed Projects allow only the declared Activity
    name change. Both desktop processes exit 0 with empty logs and all 565 package
    files unchanged. Fresh server testing passes 23 scoped assertions, including exact
    OpenAPI, Unicode/CRLF, stale 412 and acknowledged-write persistence after owned
    forced restart. No new full-suite or graceful/power-loss claim is made.

    This is an unfinished scoped Windows development prerelease, not the complete
    OA/SA release or separately owned follow-up union. Dense diagrams, remaining
    Scenario group adapters, quantities/calculations/constraints, maintained
    libraries and broad accessibility/DPI remain unfinished. Native testing used
    one existing account/machine at 1442×932 with system-only child PATH. The footer's
    complete guidance was read with a pointer tooltip; keyboard-only access remains
    untested. Linux/WSL remains user-deferred. Existing releases/tags remain unchanged.

    Exact validation, independent review, preserved evidence and build/run instructions
    identify the separate source/build/package scopes. This tag points to the
    reviewed evidence-only checkpoint e144e32e99, with production inputs unchanged.
