Mini Whiteboard V1.2.1 — Windows release + macOS preview

Mini Whiteboard V1.2.1

Windows bug-fix release with a clearly labelled macOS 14+ preview.

What changed

• Blank textbox dismissal: an outside press previously finished the editor
  and then reached the active Text tool, creating another blank editor. Empty
  and whitespace-only drafts now dismiss without starting a canvas action,
  adding history or clearing redo. A separate next click immediately creates text.
• Clearing existing text removes it in one undoable operation, restoring its exact
  content, width, transforms, masks, colour and stacking on undo.
• Old editor callbacks cannot close a replacement session. Single/double-click
  dismissal follows one input owner. Meaningful Text-mode continuation still
  commits and starts/edits the next textbox with one click, including a panned view;
  that press cannot activate an old transform handle.
• Editor context menus remain usable while embedded in the transformed view.
  Closing their menu with an outside click restores editor focus. Palette dismissal
  no longer replays a click into text creation or another canvas tool.
• Escape detection resets for a fresh global hold after idle. V1.2 hold → move →
  release creation, repeat protection, wrapped text and screenshot caching remain.
• Documentation is consolidated into usage, contribution, release, testing and
  dependency/source guides.

Verification

Check	Actual result
Windows 11 build 26200, Python 3.12.14 x64	213 discovered: 211 passed, two Mac-only skips; build gate 6.343 s
Windows native GUI/controller regressions	111 checks passed; one 1920×1080 display at 100%
External-focus W/S hold/release	49 native-input checks passed, including creation from an editor and cancellation with a popup
Native textbox audit	18 checks passed; reported loop reproduced before the fix; whitespace, rapid cycles, menus/focus, palette and deletion/undo checked
Other application clicks	Eight supplementary native assertions passed with an owned separate process; blank/nonempty edits finish and the clicked button acts once
Final Windows executable	34 packaged checks passed, including native blank dismissal, next-click typing, deletion/undo/redo and palette dismissal
Windows ZIP/notices	174 files; every CRC and file SHA-256 matches the verified build; 17 notice hashes verified; strings 1.2.1, numeric/manifest 1.2.1.0
Hosted Windows CI	213 discovered, 211 passed, two skips in 6.771 s; Windows Server 2025, Python 3.12.10 x64
Mac CI	All 213 passed in 13.697 s; repeated before build in 8.579 s
Mac actual builder	macOS 15.7.9 arm64; Universal2 Python 3.13.15; Qt/PySide6 6.11.2, PyInstaller 6.22.3, PyObjC 12.2.2
Mac bundle and startup	Universal2, 769 checks; eight-second Cocoa startup, normal termination, exit 0; minimum target/runtime/plist 14.0
Mac archive/notices	375 entries, ditto extraction plus full file/mode/symlink and bundle revalidation; 15 notice hashes verified
Mac transfer	Both Actions artifact digests verified; inner Mac-created ZIP transferred unchanged through Windows
Other checks	28 screenshot performance cases; screenshot cases retained one cache build and zero source paint/decode/geometry work; workflow lint, compilation, dependencies and documentation/source-archive links passed

The focused automated audit covers blank/whitespace drafts, existing deletion,
press/move/release, rapid/double clicks, stale callbacks, menus, other targets,
panned/transformed editing, lifecycle and history. Scripted checks use owned
windows/processes. They do not establish a full hand-operated acceptance pass.

NOT RUN: interactive Mac global shortcuts/Escape, focus/menu/Spaces,
Screen Recording permission/capture and Retina/multi-monitor acceptance;
execution on macOS 14 or Intel; physical mixed-DPI Windows arrangements,
Windows 10/clean-machine deployment, hand-operated IME/RTL/emoji and prolonged use.
Universal2 validation does not prove Intel execution. Mac remains a preview.
