Changelog

• WikiSyncService: promote DeriveTitleFromFilename and SanitizeFilename from

private to internal static; add 7 tests covering extension stripping, dash-to-

space conversion, space-to-dash conversion, invalid char replacement, and

round-trip consistency.

• MediaLibraryWatcher: promote ShouldIgnore and ShouldIgnoreDir from private to

internal static; add 11 tests covering hidden files, .DS_Store, temp files,

tilde backups, hidden directory segments, empty/dot paths, and normal files.

• FileService.DetectMimeType: already internal static; add 20 tests via

TestCase attributes covering images, documents, media, text, unknown

extensions, no extension, and case insensitivity.

• Add InternalsVisibleTo for PrivStack.Plugin.Files.Tests in Files csproj

(Notes csproj already had it).

Extract pure logic from infrastructure classes for testing:

• TaskToNoteService.BuildBlocksFromMarkdown: changed from private to internal static,

added InternalsVisibleTo for Tasks.Tests. 9 tests covering headings (all 3 levels),

paragraphs, multi-line joining, blank line separation, bullet lines as paragraph text,

empty input fallback, mixed content sequencing, and unique block IDs.

• DocxExportService.GetImageDimensions and ParseJpegDimensions: changed from private to

internal static. 4 tests covering valid PNG dimension parsing, valid JPEG SOF0 parsing,

unrecognized format defaults, and direct ParseJpegDimensions extraction.

Refactor ImapSyncService to expose pure static methods for testing:

• Extract ClassifyFolder(FolderAttributes, string) as internal static

overload; the private IMailFolder overload delegates to it

• Change MapSecurity from private to internal static
• MapProviderToConnectionId was already internal static

Add 22 tests in ImapSyncServiceTests covering:

• ClassifyFolder: attribute-based and name-based classification for all

folder types (Inbox, Sent, Drafts, Trash, Junk, Archive, Starred,

All, Category, Other)

• MapProviderToConnectionId: Gmail->google, Outlook->microsoft, and

throws for unsupported providers

• MapSecurity: all three EmailSecurityMode variants

MapToEmailMessage skipped — requires constructing MailKit's

IMessageSummary with internal/sealed Envelope types, not worth the

fragility for a straightforward field-mapping method.

Replace hover-visible up/down/remove buttons in BulletListEditor,

NumberedListEditor, and TaskListEditor with:

• Drag-to-reorder: hold and drag the list marker (bullet, number, or

checkbox) to reorder items within the same parent list. Uses Avalonia

DragDrop with 5px threshold, drop-above/drop-below indicators, and

same-parent validation to prevent cross-list moves.

• Right-click context menu: "Delete List Item" on each row, reusing

existing RemoveItem logic.

Also fixes FocusItemAtFlatIndex to handle both Grid and StackPanel

children of rowBorder (the StackPanel case occurs when ChildBlocks

are present).

Removed: CreateReorderButton, MoveItemUp, MoveItemDown methods and

all reorder-controls/reorder-btn AXAML styles.

Remove root-level left margin from BulletListEditor (20px),

NumberedListEditor (16px), and TaskListEditor (24px) ItemsPanel

containers. Top-level list items should align with other block content

(headings, paragraphs) — the BlockWrapper handle gutter already

provides the left offset. Nesting still works via depth * 24 on each

item row.
