Epic 8 — Windows App (Rust + iced)
Goal: Fast, lightweight native Windows app -- single .exe, no runtime dependencies.
Story 8.9: Portable Mode
As a Windows user who uses a USB drive, I want CalcPad to run in portable mode when a marker file is present, So that I can carry my calculator and all its data on a USB stick without installing anything on the host machine.
Acceptance Criteria:
Given a file named portable.marker exists in the same directory as calcpad.exe
When the app launches
Then all data (sheets, settings, configuration) is stored in a data/ subdirectory alongside the .exe instead of in %APPDATA%
Given portable.marker does NOT exist alongside the .exe
When the app launches
Then the app uses the standard %APPDATA%\CalcPad\ directory for storage (normal installed mode)
Given the app is in portable mode
When the user creates sheets and changes settings
Then all changes are written to the local data/ directory
And no files are written to the system %APPDATA% or registry
Given the user copies the CalcPad folder (exe + portable.marker + data/) to a USB drive When the user runs calcpad.exe from the USB on a different Windows machine Then all sheets and settings from the original machine are available
Given the app is in portable mode When the auto-update feature checks for updates Then auto-update is disabled (or updates are downloaded to the portable directory) to avoid modifying the host system
