# Contextual authoring Windows prerelease — publication

Codex-9e8r6t `/root`, 2026-09-11. **Published and read back at 17:03:29 UTC.**

[Release 3: contextual authoring Windows preview](http://217.177.34.108:3000/sorokin.oleg.edu/ARCADIA-Studio/releases/tag/v0.2.0-preview.contextual.20260911)
is public, draft false and prerelease true. It includes Studio, the optional
REST server, examples, offline help and dependency notices. Extract the complete
ZIP and run `arcadia-studio.exe`; keep `libunwind.dll` beside the executables.
Full OA/SA release acceptance remains incomplete. Linux work is user-paused.

## Artifact and source

Tag `v0.2.0-preview.contextual.20260911` points exactly to
`b2c3e54001fc19a05423bcd5808ceea78d13ff59`, confirmed through Git and Gitea REST.
Exact raw-input reconstruction is
`d5650309a93f3d590a41f8a8f0322c6500568f69`; later instruction synchronization
on its branch does not redefine this frozen commit. GUI5657 and unchanged EFEE
server retain their distinct development-profile build histories.

ZIP: `ArcadiaStudio-0.2.0-preview.contextual.20260911-x86_64-pc-windows-gnullvm.zip`.
It contains 559 files, is 32,775,691 bytes, and has SHA256
`9186d4fc9a7b52fb195c183c4847c8e3419ea6da8b3f907e0c06f9ceec58dee0`.
The public notes and attached validation record disclose raw reconstruction,
server reuse, known UI gaps, missing semantic/peer integration and Linux pause.

## Verification and publication sequence

- [Preparation](release-contextual-source-prerelease-preparation-20260911.md)
  preserved 238 GUI inputs, 120 server files, notices and exact Git checkout.
- [Independent review](release-contextual-source-prerelease-review-20260911.md)
  passed 5,231 artifact and 1,800 packaged-server checks.
- [Native package acceptance](release-contextual-source-prerelease-gui-20260911.md)
  passed real Home/help/Open/contextual Create/Save/Close, complete model/three
  source files/original identities, and all 559 unchanged package files.
- [Broader GUI5657 native acceptance](release-contextual-source-native-v2-20260911.md)
  and full 679 desktop tests retain their separate frozen-build scopes.
- Independent publication-text review found no material error; Gitea issue 1
  comment 405 records the exact reviewed notes and validation hashes.

Draft release 3 was created at 16:53:21 UTC. The first ZIP upload connection
was reset by the remote host before an attachment response. A fresh attachment
listing was empty. One retry uploaded all three files and downloaded every byte
for comparison, completing at 16:58:02 UTC. No duplicate asset was created.

The first draft-publication request returned HTTP 500 with an empty Gitea error
message. API readback retained draft true and no tag. The tag API then reported
the name already existed, while API and Git still showed no actual tag ref.
Root created only the reserved tag through a nonforce Git push to the verified
checkpoint; exact remote readback passed at 17:03:18 UTC. Publication then
completed successfully, preserving the same assets/body/target. No existing
release or tag was overwritten. A transient failed MCP issue comment was absent
on readback; later publication comment 406 succeeded and consolidated the result.

Gitea's returned `created_at`/`published_at` became **16:04:30 UTC**, the target
commit's time. The actual successful publication/readback was **17:03:29 UTC**;
the receipt preserves both values. Server metadata is not presented as the
observed execution time.
