Mini Whiteboard V1.2

Verified Windows release with a Mac preview. Hold a shortcut, move the pointer,
and release to place a whiteboard or capture a screenshot region.

Downloads and launch

  • Windows 10/11, x64: WinMiniWhiteboardV1.2.zip. Extract it, open the
    Mini Whiteboard folder, and run Mini Whiteboard.exe. Keep _internal with it.
  • macOS 14+, PREVIEW: MacMiniWhiteboardV1.2-Preview.zip. Extract on a Mac,
    move Mini Whiteboard.app to Applications and open it. Interactive Mac acceptance
    remains NOT RUN. The preview is ad-hoc signed and has not been notarized.

Both downloads include Python and Qt. Launch opens only a tray/menu-bar icon.
Windows is unsigned. If a trusted Mac download is blocked, use Apple's documented
Open Anyway process.

What changed

  • Windows Ctrl+Alt+W/S: point at the first corner, hold, move, then release
    W/S or any required modifier. W makes a board; S captures a locked screenshot
    board with Draw active. No initial board, second press, click/drag or minimum hold.
  • Mac: Control+Option+W/S, or the existing Command+Option+Shift+W/S preset,
    uses the same gesture. All four directions and negative desktop coordinates work.
  • Repeated activations and competing shortcuts cannot confirm/restart a hold.
    Escape/menu cancellation and invalid selections clear the preview. Remaining
    held S/W cannot switch the newly focused board's tool. Minimum board size stays
    160 x 100 logical units; screenshots below 4 x 4 desktop units cancel.
  • Text wraps naturally to a stored local width, with character fallback for URLs.
    Soft wraps leave plain text unchanged; Enter inserts a real newline. Editing,
    committed rendering and reopening match. Moves/transforms/window resizing keep
    the stored width. Tall text retains its content and follows the caret while editing.
  • Wrapped text hit testing avoids a Mac Qt stall from expanding every glyph's
    tolerance outline. Shaped glyph outlines still provide painted/erasure geometry.
  • Mac CI uses a free macos-15 runner. Deployment target, Info.plist and runtime
    minimum stay 14.0. No paid runner, spending or permission-policy changes.
  • F1/help, menus, current guides and the app-rendered placement GIF teach the new workflow.

Held-key defect investigation

The preserved V1.1 executable and source reproduced a board plus a renewed outline
under a hold with repeated key-down injections. MOD_NOREPEAT was already present;
the application accepted extra activation events as two-press confirmation/restart
and retained undersized anchors. V1.2 adds explicit hold/release latching and shared
ownership, and never restarts an invalid selection. A permanently unrecoverable
outline was not reproduced in the controlled diagnostic; later valid input recovered.

Actual verification

Release source: 08b3893.

  • Windows 11 build 26200, Python 3.12.14 x64: 191 discovered, 189 passed,
    2 Mac-only skips    ; final build gate 5.648 s.
  • 112 Windows native checks, 45 external-focus real input checks,
    25 packaged executable checks, plus 3 native Windows wrapped-editor tests.
  • Windows ZIP: 174 files, all CRCs and file SHA-256 values match the verified
    distribution; 17 verified dependency notice files; executable metadata 1.2.
  • Hosted Windows checks:
    191 discovered, 189 passed, 2 skips in 5.358 s; Python 3.12.10, Windows Server 2025.
  • Mac CI:
    191 passed in 9.471 s, repeated before packaging in 8.825 s. Actual runner:
    macOS 15.7.9 arm64, Universal2 Python 3.13.15, Qt/PySide6 6.11.2,
    PyInstaller 6.22.3, PyObjC 12.2.2.
  • Mac Universal2 bundle: 769 checks, signatures/linkage/symlinks/notices;
    limited Cocoa startup 8 s, exit 0; 375 ZIP entries, ditto extraction and
    full file/mode/symlink revalidation; 15 verified dependency notice files.
  • Both Actions artifact digests matched; the Mac-created inner ZIP was transferred
    unchanged. It was never extracted/recompressed as an app on Windows.
  • Existing performance workloads, screenshot display cache invariants, workflow
    lint, source compilation, dependency consistency and documentation links checked.

NOT RUN: interactive Mac shortcuts/releases/Escape, focus/menu/Spaces/TCC,
real Retina/multi-monitor behaviour; macOS 14 or Intel execution; physical mixed-DPI,
Windows 10/clean-machine deployment, hand-operated IME/context menus and extended use.
Universal2 structural validation does not establish execution on Intel or macOS 14.
