# Compact Help Windows preview validation The exact [published validation and build/run instructions](http://217.177.34.108:3000/sorokin.oleg.edu/ARCADIA-Studio/src/commit/f1fdca371394aec1148e67f33f4d8c6b53a0c350/harness/release-compact-help-validation-20261001.md) are authoritative. They link native screenshots, raw HTTP exchanges, complete source/model comparisons, independent reviews and all 140 preserved evidence files. This attachment is a portable entrypoint to those records. Desktop production source: 6e7c4ddaf0775198384a8c4882809ea8e14b2976. Unchanged server artifact source: 715036e132677dd2bc2fb37ed316d93dc9987aec. Packaged documentation source: ea23e229260d7d050b3c3b88e77c3a851e936abe. Release/evidence checkpoint: f1fdca371394aec1148e67f33f4d8c6b53a0c350. The binaries use the dev/unoptimized Windows gnullvm profile. ZIP: 34,184,534 bytes; SHA256 `18af75c7aea60bb0d5db5b1925d0d0815ecd08afc5bb258438851cfda809a6f2`. Verify the ZIP against its companion, extract the entire folder and launch `arcadia-studio.exe` with `libunwind.dll` beside it. Read `START-HERE.txt`. Home opens the water-pressure example; Help/F1 reads the offline guide. Copy complete example folders before editing. Save All updates loaded source; Save As requires a fresh source destination. Companions need separate copying. Optional server in a writable working directory: ```powershell .\arcadia-server.exe --bind 127.0.0.1:8787 --data-dir C:/ArcadiaModels/server ``` See packaged docs/server.md and docs/api.rst for REST/deployment/authentication. No remote deployment is claimed. Verified final formatting, strict desktop Clippy, GUI build and 125 focused tests, plus independent source/native/artifact review and fresh extracted desktop/server workflows. The earlier full desktop run is separately scoped; 1,421 unrelated final tests were not rerun. Exact Save/Undo/Redo, fresh-folder Save As, reopen/no-op Save and complete model/source comparisons pass. Both desktop runs exit 0 with empty logs. Server stale-write refusal and acknowledged write persistence pass, using owned forced restarts, not graceful/power-loss testing. Current native package QA uses one machine/account with restricted PATH. This is an unfinished scoped Windows development preview. Complete OA/SA, dense diagram readability, remaining Scenario adapters, calculations/constraints, maintained libraries and broad accessibility/DPI acceptance remain unfinished. Linux/WSL is user-deferred. Save As collision wording remains misleading in this package and is tracked in issue 46; file protection and recovery are verified. Separately owned follow-up contributions are excluded. Existing releases remain unchanged.
