The save picker used to return only TryGetLocalPath(), so a target without a
local path looked like a cancel and nothing was written. The dialog service now
hands back an opener for the chosen file. The picker call is inside the error
handler, and the workspace is read before the target is opened, so a failed read
leaves an existing file untouched.
A failed read on a UI path (sort change, clear, refresh after a write, opening a
card, the tag picker, the tags tab) used to escape as an unhandled exception.
Reads now run before the view is cleared and report Error_Read_* instead; the
active filter changes only once its query has run. DataWritten and TagsChanged
fire only after a successful refresh, so a broken database shows one dialog.
With .ykanban present but ykanban.db gone, opening used to create an empty
database and show an empty board without any hint. It now throws
WorkspaceDatabaseMissingException and shows the open-failed page, telling the
user to restore a backup or delete .ykanban and initialize again.
- board: columns in id order, per-column sort via config, column width presets (240/320/480) and custom 160-720
- column header new-card and edit/delete menu; card menu delete and move-to-column
- card editor as one unit of work with dirty check and discard confirmation; nested tag picker writes new tags immediately
- schema constraint violations mapped to typed exceptions and shown inside the modal
- dialog service with owner stack so nested modals center on their parent and get FlowDirection
- repository: filtered GetCards, CountCards; view-model tests
