# Integrated modeling and text authoring — Windows development preview
This preview brings together changes made since the September12 rename preview:
- Text workspace and preview-state fixes, plus source-preserving Tab/Shift+Tab
indentation with Undo/Redo.
- Saved Scenario arrangements, occurrence-specific Details and editable service
values, with clearer draft recovery and inspector actions.
- Multiple selection in ordinary and State diagrams; supported Process sibling
reordering and exact read-only navigation into reused Process contents.
- Allocation group assignment and explicit Arrange, plus direct OA/SA Allocation
drawing between a performer and compatible unallocated leaf work.
- Ordinary edge attachment controls, State bend editing and semantic port
presentation controls.
- Traceability-view guidance and cross-layer placement, transition review counts
and conflict guidance, and picker-first Escape handling.
Download the Windows x86-64 (`x86_64-pc-windows-gnullvm`) Studio ZIP and its
SHA256 companion. Verify the ZIP SHA-256, extract the entire folder and run
`arcadia-studio.exe`, keeping `libunwind.dll` beside both executables.
The package includes the optional REST server, examples, offline help and
dependency notices. Read `START-HERE.txt`, `docs/windows-packaging.md` and the
release's `VALIDATION.md`. Copy a complete example folder before editing; Save As
alone is not a copy of every referenced source/evidence file.
Use `docs/preview-human-checks.md` for feature checks. Supplemental State/
Traceability and Allocation/Process model kits provide small examples for the
new interactions. Their own README files identify their original fixtures and
expected operations. Report the package version from `package.json`, the model
and reproducible steps.
Source: **715036e132677dd2bc2fb37ed316d93dc9987aec**. Combined Windows gates
pass 2,200 tests with eight existing ignores and no failures, strict workspace
all-target Clippy and the individual desktop/server builds. All 29 required
regression cases passed. The distributed binaries come from the individual
Cargo build commands recorded in the [reviewed build evidence](http://217.177.34.108:3000/sorokin.oleg.edu/ARCADIA-Studio/src/commit/1a6f2e4f9e8e56a0b4eedd19723a0a0001260300/harness/reviews/prerelease37-final04-complete-20260924.md).
The supplemental combined desktop/server build also passed, but produced
different bytes; its binaries were not selected for this package. Individual
dependency events show differing feature sets; a sole cause is not established.
Verified Studio ZIP: **34,168,661 bytes**, SHA-256
`5554e32533e3cb2c33fb4143a5a0902733d5a8d47577303cb2842d268e7bc76d`.
Independent downloads verify this exact archive and all packaged files. Reviewed
Windows trials cover State bends and Undo/Redo, picker/tool cancellation, guide
rendering, Save and fresh-process reopen. Packaged REST checks verify conditional
writes, stale-write rejection and acknowledged-write persistence across an
owned forced restart. The attached `VALIDATION.md` links the exact raw evidence
and independent reviews, including a second Windows machine.
This remains an unfinished development-profile prerelease. Crossed Process
routes and multiline State labels can obscure text or endpoints. Aggregate
model removal, remaining Scenario group adapters, full public source8 support,
complete OA/SA acceptance and broad accessibility/DPI coverage remain unfinished.
Native automation does not cover every held-input gesture. Linux/WSL builds stay
deferred at the user's request. The private analysis-index work and post-freeze Scenario selection increment
are excluded. In State Edit transition, Escape dismisses the dropdown; use
explicit Cancel to close the form. See `VALIDATION.md` for bounded checks and
retained harness failures/recoveries.
