    Accurate Save As diagnostics — Windows development preview Pre-Release

    Codex-9e8r6t released this 2026-10-02 03:26:28 +00:00 | -209 commits to main since this release

    Save As destination collisions now explain that existing files are protected
    and offer clear recovery: choose a fresh source directory, or use Save All at
    the current entry. Genuine observed external edits keep their distinct
    external-change diagnosis. This preview includes the prior compact diagram
    controls and contextual Help; model/source/history semantics and REST contracts
    are unchanged.

    Download the Windows x86-64 Studio ZIP and checksum, verify SHA256 and extract
    the whole folder. Launch arcadia-studio.exe, keeping libunwind.dll beside both
    executables. Read START-HERE.txt and the attached VALIDATION.md. Copy a complete
    example before editing; Save As copies model source with existing include paths,
    so companion/external artifacts need separate copying. The optional REST server,
    examples, offline guide and notices are included.

    Desktop source 0e83157e09; packaged documentation
    ef28f1784e. The server is the unchanged released
    715 artifact with recovered original build provenance and fresh tests of this
    bundle's selected runtime. Both binaries use the dev/unoptimized profile;
    packaging did not rebuild them.

    Verified: 29 targeted desktop save checks, formatting, strict Clippy and matching
    GUI build; exact archive/extraction/notice/documentation identities; fresh
    independent source/artifact/native/REST/claims review. Two actual extracted
    desktop sessions exercise Apply, accurate refusal and recovery, genuine external
    edit protection, fresh Save As, reopen and no-op Save All. Complete 37-file byte
    oracles and full 30-source-file parsed Projects allow only the declared Activity
    name change. Both desktop processes exit 0 with empty logs and all 565 package
    files unchanged. Fresh server testing passes 23 scoped assertions, including exact
    OpenAPI, Unicode/CRLF, stale 412 and acknowledged-write persistence after owned
    forced restart. No new full-suite or graceful/power-loss claim is made.

    This is an unfinished scoped Windows development prerelease, not the complete
    OA/SA release or separately owned follow-up union. Dense diagrams, remaining
    Scenario group adapters, quantities/calculations/constraints, maintained
    libraries and broad accessibility/DPI remain unfinished. Native testing used
    one existing account/machine at 1442×932 with system-only child PATH. The footer's
    complete guidance was read with a pointer tooltip; keyboard-only access remains
    untested. Linux/WSL remains user-deferred. Existing releases/tags remain unchanged.

    Exact validation, independent review, preserved evidence and build/run instructions
    identify the separate source/build/package scopes. This tag points to the
    reviewed evidence-only checkpoint e144e32e99, with production inputs unchanged.

    Compact diagram controls and contextual Help — Windows development preview Pre-Release

    Codex-9e8r6t released this 2026-10-02 01:22:51 +00:00 | -203 commits to main since this release

    This Windows development preview recovers diagram space by moving instructional
    text into contextual Help. Use Help · F1 to read the relevant guide, scroll
    with PageUp/PageDown/arrows/Home/End, and return with Escape or Close while keeping
    the exact property draft, caret, selection and view. Compact selection controls
    and full allocation destinations remain available; cancelling Arrange clears its
    obsolete armed status.

    Download the Studio ZIP and SHA256 companion, verify the hash and extract the
    whole directory. Run arcadia-studio.exe with libunwind.dll beside it. The bundle
    includes the optional REST server, examples, offline Help and dependency notices.
    Read START-HERE.txt and the attached VALIDATION.md. Copy a complete example
    folder before editing; use Save All for the loaded project or a fresh source
    destination for Save As. External artifacts/tutorial companions need separate
    copying.

    Desktop production source: 6e7c4ddaf0; package
    documentation: ea23e22926. The server is the
    unchanged released 715 artifact, with explicit provenance and fresh checks against
    this bundle's selected DLL. Binaries use the dev/unoptimized profile.

    Verified: final formatting, strict desktop/all-target Clippy, GUI build and
    125 focused tests. The earlier full desktop result and final coverage limits are
    recorded separately in VALIDATION. Independent source/native/artifact review and
    fresh extracted-package checks cover Home/Help, minimum-size editing, exact caret
    return, Apply/Save/Undo/Redo, fresh-folder Save As, fresh-process reopen/no-op Save,
    complete source/model comparison, notices and all 565 files. Both desktop runs
    exit 0 with empty logs. Fresh server checks pass exact OpenAPI, conditional writes,
    stale-write refusal and acknowledged-write persistence after restart.

    ZIP: 34,184,534 bytes, SHA256
    18af75c7aea60bb0d5db5b1925d0d0815ecd08afc5bb258438851cfda809a6f2.

    This remains an unfinished Windows development prerelease. Dense routes/labels,
    remaining Scenario group adapters, quantities/calculations/constraints,
    maintained libraries, complete OA/SA acceptance and broad accessibility/DPI
    coverage remain unfinished. Separately owned projection/navigation, outgoing-drag,
    icons, grid/performance and State-label increments are excluded. A protected Save
    As collision currently has misleading external-change wording, tracked in
    issue 46;
    the refusal preserves files and normal Save All/fresh-folder recovery passed.
    Server restart tests do not establish graceful shutdown or power-loss safety.
    Linux/WSL remains deferred at the user's request. Existing published previews are
    unchanged; this is the scoped #39 contribution, not the combined follow-up release.

    Exact validation, evidence and build/run instructions
    identify the separate desktop, server and package documentation inputs. The tag
    points to this published evidence checkpoint; production inputs are unchanged.

    Integrated modeling and text authoring — Windows development preview Pre-Release

    Codex-956atf released this 2026-09-24 22:45:56 +00:00 | -197 commits to main since this release

    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: 715036e132. 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.
    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.

    Source alias rename — Windows development preview Pre-Release

    Codex-9e8r6t released this 2026-09-13 00:46:38 +00:00 | -25 commits to main since this release

    Source alias rename — Windows development preview

    Rename an alias from its declaration or reference in the Text editor with F2. Review the changed source lines, then confirm. Model identity is preserved; an immediate Undo Rename is available, and Save all remains explicit. File and row navigation reset the preview to the selected destination. Comments and descriptive prose remain unchanged.

    Download the Windows x86-64 ZIP and its SHA256 companion. Extract the entire ZIP and run arcadia-studio.exe, keeping libunwind.dll beside it. The bundle includes the optional REST server, examples, offline guide and dependency notices. See START-HERE.txt, docs/windows-packaging.md and docs/server.md inside the bundle.

    Both executables come from source cbc49a7802. Strict Clippy, 805 desktop tests, the isolated Confirm timing check, and 501 core/server tests passed. Independent verification covered all 559 package files, source/artifact bindings, dependency notices and documentation. Actual packaged-server persistence/restart checks and minimum-window desktop rename, Undo/Redo, Save and representative reopening passed. VALIDATION.md identifies the precise workflows, evidence and verification commands.

    This is a Windows development-profile prerelease, with debug assertions enabled. Full OA/SA acceptance, optimized builds, the compact Text workspace and newer peer diagram/palette work remain unfinished. A known scroll-state limitation can let a delayed preview reset affect a visit after switching Full details back to Preview; its isolated correction is tracked in issue 9. Linux/WSL work remains paused at the user's request.

    Arcadia Studio — canvas and source repair Windows preview Pre-Release

    Codex-ytr83r released this 2026-09-12 12:01:59 +00:00 | -22 commits to main since this release

    This Windows preview combines editable behavior canvases, contextual source and child-work creation, lifecycle rendering, grapheme-safe label shortening and safer source repair. Repairing a different file to previously accepted content now stays unsaved until that destination is written; interrupted-save recovery preserves the current model and its history.

    Download the Windows ZIP, extract the entire folder, then run arcadia-studio.exe. Keep libunwind.dll beside the executables. The bundle includes the optional REST server, examples, offline help, documentation and dependency notices. Read START-HERE.txt and the attached VALIDATION.md. Copy a complete example folder before editing. The standalone source CLI is distributed separately.

    Verified: 761 desktop tests, strict desktop Clippy and the matching GUI build. Native checks on this package cover repair/Close/Cancel/Save, graphical Undo/Redo, prepared-journal recovery, Unicode selection/source preservation, bundled example/help and normal exit0 with empty logs. All559 package files stayed unchanged. Fresh packaged-server checks passed25 REST editing/persistence requests. Earlier source-bound creation, child-work and camera evidence is identified separately in VALIDATION.md.

    This is an unfinished, unoptimized development prerelease. Long wide labels can remain clipped, and labels at small fitted zoom are hard to read. Full keyboard/accessibility and arbitrary font/DPI coverage, evaluated quantities/calculations/constraints, maintained libraries and complete OA/SA parity remain unfinished. The separately published peer source-navigation features are not included in this canvas contribution. Linux/WSL work remains user-paused.

    The tag identifies Studio source 33e30c1cd7. The optional server is the unchanged artifact from source321897f, with separate provenance. Exact validation and evidence.

    Source navigation — Windows development preview Pre-Release

    Codex-9e8r6t released this 2026-09-12 10:52:54 +00:00 | -16 commits to main since this release

    Source navigation — Windows development preview

    Navigate between declarations and references in the Textual model with F12, Shift+F12 and Alt+Left. Navigation follows included files and current drafts, supports Unicode names, asks you to choose ambiguous declarations, and identifies incomplete or stale results.

    This preview also fixes source-panel movement during diagnostic refresh, Find dismissal and focus, an empty panel after Back, Windows system-menu input, and repair/recovery cases that could incorrectly report changes as saved. Applying repaired text keeps it unsaved until its destination is saved.

    Download and extract the whole Windows ZIP, then run arcadia-studio.exe. Keep libunwind.dll beside the executables. Examples, offline engineering help, documentation and the optional REST server are included. Read START-HERE.txt and the separate VALIDATION.md release attachment for launch commands and verification scope.

    Verified: 755 desktop tests passed (one ignored), strict Clippy and a matching desktop build. Native checks cover navigation and the 30-file engineering example on the preceding navigation build, repair/rollback on the corrected build, and a fresh launch of this exact package with navigation, edit/Undo, Apply, Save and complete saved-model/source comparison. Independent package and server checks passed, including complete model/source persistence through restart. The packaged desktop exited with code 0; all 559 package files stayed unchanged.

    This is an unfinished development prerelease, with unoptimized binaries. Text alias rename, newer peer canvas/lifecycle changes, complete quantities/calculations/constraints, maintained libraries and full OA/SA acceptance remain unfinished or outside this milestone. Linux/WSL work remains user-paused.

    The tag identifies exact desktop input reconstruction 802855f7e6f2f00a107a12196b458b267f586b8d, based on corrected source 33c6d83e9ba9a5b1310b1b627d7c40affcbcf15c. The optional server is the unchanged September 7 artifact with separately recorded source provenance; it was not rebuilt from the navigation source. See VALIDATION.md for the distinct build scopes and evidence links.

    Arcadia Studio — contextual authoring Windows preview Pre-Release

    Codex-9e8r6t released this 2026-09-11 16:04:30 +00:00 | -4 commits to main since this release

    This Windows x64 preview lets you create a missing Activity, Function or state-machine owner while filling in the behavior form. It retains the parent draft and keeps the essential fields and action buttons visible in a small window. Studio, the optional REST server, examples, offline help and dependency notices are included.

    Run: download the ArcadiaStudio ZIP, extract the whole folder, then open arcadia-studio.exe. Keep libunwind.dll beside the executables. Use Home's water-pressure walkthrough to explore OA/SA, and copy a complete example folder before editing. START-HERE.txt and docs/server.md explain the portable bundle and server.

    Verified build: all 679 desktop tests passed, plus 26 focused layout tests, strict Clippy, formatting and the matching GUI build. Real native tests passed minimum-size layout, draft recovery and cancellation, direct Lifeline creation with Undo/Redo, and state-machine creation with Undo/Redo and a fresh-process reopen. Complete model, source-file and original-identity comparisons passed. The package contains 559 files with strict dependency notices and archive readback.

    Fresh package checks: the desktop opened with a private profile and Windows-only PATH, displayed offline help, and created and saved a lifeline with a new activity source. The complete model/source/identity oracle passed, and all 559 package files remained unchanged after close. Independent packaged-server checks passed exact health/OpenAPI, model creation and source persistence across restart. The first custom test environment omitted a Windows path variable; its preserved inventory failure was resolved by a fresh extraction and corrected launcher. See VALIDATION.md for the exact scope and history.

    Known limitations: this is an unfinished Windows milestone using development-profile binaries. Some scenario forms retain a previous scroll position, and dense labels remain crowded. Further canvas/chooser/lifetime improvements, text-navigation integration, executable calculations, dimensional quantities and maintained libraries are still in progress. Linux work is paused at the user's direction. The separately published CLI is not included in this ZIP.

    Source checkpoint: b2c3e540. The exact input snapshot records the measured raw inputs, including eleven newline restorations. It is a reconstruction, not the original build commit. The server is the unchanged, previously verified EFEE artifact; it was not rebuilt with this GUI. See VALIDATION.md for per-binary provenance and check scopes.

    Arcadia CLI — standalone Windows authoring preview Pre-Release

    Codex-9e8r6t released this 2026-09-11 12:50:39 +00:00 | 2 commits to main since this release

    Standalone Windows x64 tools for .arcadia projects: check/lint, missing-ID stabilization and semantic alias rename. Editing commands preview by default; --write saves through the shared source conflict/recovery guards. Studio and a server are not required.

    Extract the complete ArcadiaCLI ZIP, keep libunwind.dll beside arcadia.exe, and open a terminal in that folder:

    .\arcadia.exe --help
.\arcadia.exe check examples/text-first/project.arcadia

    Copy a complete example folder before editing. Read docs/source-cli.md for command, diagnostic and exit-code contracts. Preview IDs remain provisional until saved; a later invocation can generate different missing IDs.

    Verified: 12 source CLI tests, strict lint/format/build, independent 183 semantic assertions across 21 processes, all 114 packaged files and 27 dependency packages, plus independent source/default compatibility and 156 assertions across 10 clean extracted CLI invocations. Preview, exact stabilization/rename, preserved identities/comments/Unicode/CRLF, no-op timestamps and invalid-source refusal passed. ZIP, checksum and validation asset were downloaded and hash-verified after upload.

    This is a development-profile Windows preview. It does not provide a saved-plan/digest protocol, complete large-model text ergonomics or current Linux runtime acceptance. It is separate from the Studio preview. The full OA/SA release remains under development.

    Release checkpoint: 27df4a3. Preserved semantic build source is 01b76a1; packaging-only assembly is a0a48e8. Attached VALIDATION.md records exact evidence and the distinct source/build roles.

    Arcadia Studio — named authoring Windows preview Pre-Release

    Codex-9e8r6t released this 2026-09-11 12:40:51 +00:00 | 5 commits to main since this release

    This Windows x64 preview adds named Process, Scenario and State machine creation, source-preserving Undo/Redo and recovery, and concise multi-file modeling examples. It includes Studio, the REST server, offline help and dependency notices.

    Run: download the ArcadiaStudio ZIP below, extract the entire folder, then open arcadia-studio.exe. Keep libunwind.dll beside the executables. On Home, choose Open water-pressure walkthrough to explore the bundled OA/SA example. Copy its complete example folder before editing. START-HERE.txt and docs/server.md explain the optional server.

    Verified: named creation, exact source/history and crash-recovery workflows on this GUI; 653 desktop tests with subsequent affected tests and strict lint/build checks; strict dependency notices and all 559 archive files. A fresh-profile, clean-PATH extraction launched Studio, opened OA/SA diagrams and offline help, and saved the example without changing its source. Independent packaged-server checks passed health, exact OpenAPI, model create/get and complete source/model persistence across restart. Uploaded ZIP and checksum were downloaded and matched exactly. See the attached VALIDATION.md for artifact identities, detailed evidence and scope.

    Known limitations: this is an unfinished milestone using development-profile binaries. Scenario forms can retain a prior scroll position, and some long labels/state-transition captions remain crowded. New contextual source creation, reference chooser changes and B4 lifetime rendering are still being integrated. Executable calculations, dimensional quantities and maintained libraries are not complete. A current Linux build has not been accepted. The separately committed CLI is not included in this Studio ZIP.

    Source base: 2ec72d4. The exact input snapshot preserves seven measured CRLF differences; it is not presented as the original build commit.
