## Download and run

ZIP: `ArcadiaStudio-0.2.0-preview.rename.20260912-x86_64-pc-windows-gnullvm.zip`,
33,074,937 bytes, SHA256
`d2433b5b384256b551672bf115bab40b3496aeee115e067922aedb5becf34d7e`.
Compare `Get-FileHash -Algorithm SHA256 <downloaded ZIP>` with this value and the
companion checksum file. Extract the entire ZIP into a fresh directory, then run
`arcadia-studio.exe`. Keep its sibling `libunwind.dll`; no compiler installation
is required by the packaged runtime dependencies.

In Text, place the caret on a declaration alias or typed reference and press F2.
Enter a valid replacement, request Preview, inspect the changed lines and confirm.
Save all writes the accepted transaction; immediate Undo Rename is also available.

For the optional server, run from the extracted directory:

```powershell
.\arcadia-server.exe --bind 127.0.0.1:8787 --data-dir .\server-data
```

`docs/server.md` describes authentication, API usage and deployment; `START-HERE.txt`
and `docs/windows-packaging.md` describe the bundle. No remote service deployment
is claimed by this release.

The simple GUI workflow tested first-key replacement and Text Undo, then Save,
model Undo/Save and Redo/Save. The representative workflow inspected all six
changed lines and row/file scroll destinations, tested dedicated Undo Rename,
Redo/Save, reopened and inspected the graphical alias. It did not test a
representative first key or reopen the simple fixture. The guide opened and was
readable at minimum size. Sixty-six capture states preserve 73 JPEGs; screenshots
and saved-state oracle results establish different aspects of acceptance.

GUI closure: `2026-09-13T00:26:58.697468Z`, exit 0, both output logs empty.
The two server children instead used intentional Windows termination after
persistence checks, both exit 1. That is not graceful-shutdown or crash evidence.
Independent archive and document reviews are included at the linked evidence homes.

## Rechecking the evidence and source

Each archive README identifies its stored verifier and exact extraction command.
Those Python standard-library verifiers check stored bytes, CRCs and historical
receipt relationships without executing the archived application helpers. Large
external package/source/cache artifacts are explicitly hash-referenced where
omitted. These are evidence verification tools, not reproducible-build claims.

The source gates used Rust/Cargo 1.98.1, Windows `x86_64-pc-windows-gnullvm`,
`clang.exe`, one Cargo build job and prepopulated locked offline dependencies.
Both binaries have opt level 0, debuginfo 0, debug assertions and overflow checks
enabled. Exact environment and commands are in the archived gate records.
From that source checkout with the recorded toolchain configured:

```text

cargo test --locked --offline -p oa-desktop --bin arcadia-studio -- --test-threads=1

```

## Remaining limitations

This is a development-profile Windows prerelease, not completed OA/SA or optimized
performance acceptance. Full Details -> Preview can reuse a preview visit identity,
allowing an earlier delayed scroll reset to affect that visit; the static P2 finding
and isolated correction are tracked in [issue 9 comment 743](http://217.177.34.108:3000/sorokin.oleg.edu/ARCADIA-Studio/issues/9#issuecomment-743).
It does not establish model/history corruption, and this trial did not exercise
the delayed-operation Details round-trip. The dense Text header, compact workspace,
inline annotations, palette and newer peer diagram work remain separate.
An older run's system-menu-triggered alias invalidation has an unproven cause;
border resizing in this trial does not prove it fixed. Capture pauses and process
lifetime are not native latency measurements. Comments/prose are intentionally
excluded from semantic alias changes. Linux/WSL work remains user-paused.
