# Published navigation Windows prerelease

[v0.2.0-preview.navigation.20260911](http://217.177.34.108:3000/sorokin.oleg.edu/ARCADIA-Studio/releases/tag/v0.2.0-preview.navigation.20260911) is published as Gitea release 4 with `draft: false`, `prerelease: true`. Root's actual publish command ended successfully; final metadata, exact tag target and all three asset downloads passed at **2026-09-12 10:54:02.303380 UTC**. The publish PATCH began at 10:53:54.264100 UTC. The API's `publishedAt: 10:52:54Z` is the draft-creation timestamp and is not evidence of public visibility at that earlier time.

This is a bounded Windows development milestone, not final application acceptance. The [published validation](http://217.177.34.108:3000/sorokin.oleg.edu/ARCADIA-Studio/releases/download/v0.2.0-preview.navigation.20260911/VALIDATION.md) gives launch instructions, provenance, verification and known limitations; its exact bytes are also [archived](experiments/navigation-prerelease-publication-20260912/payload/publication/VALIDATION.md).

## Download and launch

Download the [Windows ZIP](http://217.177.34.108:3000/sorokin.oleg.edu/ARCADIA-Studio/releases/download/v0.2.0-preview.navigation.20260911/ArcadiaStudio-0.2.0-preview.navigation.20260911-x86_64-pc-windows-gnullvm.zip) and [checksum](http://217.177.34.108:3000/sorokin.oleg.edu/ARCADIA-Studio/releases/download/v0.2.0-preview.navigation.20260911/ArcadiaStudio-0.2.0-preview.navigation.20260911-x86_64-pc-windows-gnullvm.zip.sha256). Extract the complete ZIP into a writable folder and run `arcadia-studio.exe`, retaining `libunwind.dll` beside the executables. No Rust compiler or machine PATH change was required in the tested Windows runtime. Home and Engineering guide provide offline help. Copy all of `examples/release1` into a working area before opening its `project.arcadia`; keep its supporting evidence files.

Optional server from PowerShell in the extracted folder:

```powershell
.\arcadia-server.exe --bind 127.0.0.1:8080 --data-dir "$env:LOCALAPPDATA\ArcadiaStudio\server-data"
```

Consult `docs/server.md` and `docs/openapi.json` for server use. Cargo/Docker builds require the source checkout, not only the binary ZIP; `docs/windows-packaging.md` records build prerequisites. The binary uses the recorded development profile; optimized or reproducible binary output is not claimed.

## Exact published bytes and provenance

| Asset ID | Asset | Bytes | SHA256 |
| --- | --- | ---: | --- |

The 559-file package contains B183…8848 Studio, historical EFEE…E665 server and F456…E7D4 DLL. The tag points exactly to [802855f7e6f2f00a107a12196b458b267f586b8d](http://217.177.34.108:3000/sorokin.oleg.edu/ARCADIA-Studio/src/commit/802855f7e6f2f00a107a12196b458b267f586b8d), the reconstruction of all 500 raw desktop build inputs, including 15 measured newline restorations. The actual build captured `eeeaa126` plus the repair delta later committed as `33c6d83`; reconstruction is not the original build commit. The server retains its separately verified September 7 provenance and was not rebuilt from this tag. [Producer evidence](release-navigation-prerelease-preparation-20260911.md) and [independent review](release-navigation-prerelease-review-20260911.md) give exact binary hashes and source relationships.

## Publication sequence and retained failure

The initial tag preflight at 10:49:06–07 UTC refused because the published source branch moved. It did not reach tag push. Root's stored inspection found exactly three single-parent commits modifying only `AGENTS.md`, with inspected branch head `0c9ee1505774a0f64c5f3a58b0da64a4673d5000`. The independently reviewed adjustment pins that exact branch head separately from the unchanged `802855…` tag target, rather than accepting arbitrary descendants or moving source. [Source-advance review](experiments/navigation-prerelease-publication-20260912/payload/review/SOURCE-ADVANCE.md) preserves the evidence and narrow correction.

Root published acceptance records at `f5e1c734dadd6e0203288065dac7b2e3f140cacf` before release visibility and reports exact remote Git blob readback of both native and independent reports. The archived acceptance push receipt independently records the successful branch push; the blob readback is attributed to root's tool observation rather than invented as a separate raw receipt.

The fresh nonforce tag attempt passed at 10:52:41 UTC. Root created owned draft release 4, uploaded assets 10/11/12 and downloaded each for exact byte verification, finishing at 10:53:30 UTC. Publication downloaded and verified all assets again before changing visibility, then rechecked final metadata/tag/assets/download hashes. The terminal receipt at 10:54:02 UTC records success with the same three asset identities and public prerelease state. No foreign release adoption, replacement asset, forced tag or silent version substitution occurred in this sequence. Later fresh MCP metadata readback, shared records and integration are root-owned and are not claimed by this archive.

## Accepted scope and limitations

The corrected desktop gates recorded 755 passing tests, zero failed, one ignored, strict all-target Clippy, formatting and a matching development build. Independent artifact review passed 6,002 checks; packaged server review passed 1,801 checks including exact Unicode project persistence across restart. Server processes were explicitly terminated after acknowledged persistence (Windows exit 1); graceful drain and comprehensive API editing were not tested.

[Packaged native acceptance](release-navigation-prerelease-native-20260911.md) records real Windows Open of the four-source Unicode fixture, offline guide, F12, one lexical reference excluding prose/comments, Back, dirty/stale feedback, Undo, Apply and explicit Save. Exact model, identities, four reachable sources and four disk files matched. All 126 modules were under Windows or package paths. The original closure helper failed without capturing the Win32 error; a separate query established the same process creation exited with code 0 and unchanged ZIP/full package map. The original failure remains distinct. This package trial used a 1440×900 client and did not repeat the earlier minimum-size, 30-file engineering or corrected repair/rollback trials linked in [integrated navigation evidence](release-text-navigation-integrated-20260911.md).

Text alias rename is not implemented. Newer peer canvas/lifecycle work, full quantities/calculations/constraints, maintained model libraries, comprehensive OA/SA graphical/text/REST parity, remaining engineering workflows and final independent application review are not accepted by this release. Linux/WSL setup, diagnostics, builds and checks remain paused by the user.

## Preserved publication evidence

[Archive](experiments/navigation-prerelease-publication-20260912/README.md) preserves 34 original files (103,111 bytes), exact final notes/validation/bindings, initial historical adapter manifest/README, predecessor helpers, three static review stages, source inspection and failed/successful attempt records. An explicitly labeled reconstruction reproduces the initial reviewed E679…2C99 adapter hash; it is not represented as a retained original execution snapshot. The read-only archive verifier checks hashes and receipt relationships without importing publication code or accessing network, credentials, applications or original packages. No runtime, server, package or GUI tests were repeated during archival.
