SocketsHttpHandler does not exist in the browser: setting UseCookies or AllowAutoRedirect throws PlatformNotSupportedException, so a MarkdownServices created in a WebAssembly app failed in its static initializer. The browser now uses HttpClientHandler; the fetch API follows redirects itself, so the per-hop policy check applies on desktop only. Desktop behavior is unchanged.

…chors MarkdownView gets block-level mapping between Markdown source offsets and rendered positions, so an editor preview can sync its caret and scroll: - ScrollToSourceOffset(offset) scrolls to the deepest block containing the offset (list items and paragraphs inside quotes included). The result says why nothing moved: NoDocument, OutOfRange or LayoutPending. - GetSourceRange(TextPoint) and GetSelectionSourceRange() map a rendered point or the selection back to the source range of the blocks it covers. TextPoint.Offset is an offset in the segment's plain text, never a source offset, so emphasis and links cannot be mistaken for source columns. - CaptureAnchor() / RestoreAnchor() save the character at the top of the outer ScrollViewer plus its pixel displacement, so width, font or theme changes keep the reading position. Anchors are tied to the new MarkdownView.DocumentId (not the snapshot Generation, which also changes on Complete()), so an anchor never restores onto a different document. - SourceText.ToLocation / ToOffset define the line/column convention: UTF-16 code units, CRLF counts as 2 and is not normalised.

…e source Task checkboxes stay read-only by default. With MarkdownView.IsTaskInteractionEnabled, a click on the box (or Space/Enter once it has focus) raises TaskToggleRequested instead of changing anything: StreamMark never edits the source or the snapshot, the host decides, edits its own text and assigns it back. A rejected request leaves the screen unchanged. - ListItemBlock.TaskMarker holds the source range of "[ ]" / "[x]", taken from Markdig's TaskList span. It enters ComputeFingerprint as a position relative to the list item, so a list that merely shifts does not produce an Update. - TaskToggleRequestedEventArgs carries the marker range, current and requested state, DocumentId and snapshot Version; ApplyTo(source) replaces only the character inside the brackets, so indentation and CRLF are preserved. MarkdownView.IsCurrent(request) lets the host reject a stale request. - Requests are only raised for a complete snapshot, not while streaming. - Clicking the task text still selects text. Task items expose a CheckBox automation peer with IToggleProvider. Closes #7 Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com>
…ross a full-text replace MarkdownView.RefreshMarkdown(text) replaces the whole text without clearing the view. Assigning Markdown still means "a new document" and resets everything; StreamingDocument stays append-only. - The old content stays on screen until the new text is parsed. The view remembers StreamingDocument.Version at refresh time and does not apply a snapshot that has not caught up, so rapid A -> B -> C updates never show A or B once C is accepted. - SnapshotEdit aligns the old and new snapshots by content: common prefix and suffix, then a longest-common-subsequence match of what lies between (falls back to positional pairing above 1M block pairs). Blocks that only moved because text was added or removed before them become Update ops, so their views, layout and block state survive. No new DiffKind, so the three switches stay as they are. SnapshotDiff alone would treat every block after an insertion as removed and re-inserted. - BlockStateStore.Remap, SelectionRemap and the reading anchor follow the alignment. A selection endpoint inside a rewritten block is clamped to the paired new block; inside a deleted block it moves to the start of the next surviving block (or the document end), and a selection whose ends land on the same point is cleared. - StreamingDocument.Load is now atomic (clear, write and mark complete under one lock) so the worker can no longer pick up an incomplete intermediate snapshot between Reset and Complete. StreamingDocument.Version is exposed. - The Gallery NativeAOT smoke test checks the new alignment, task marker and line/column paths (0 IL warnings, all checks pass). - Notes the timing-sensitive LongCodeTests assertion as a known local flake.

Notes for review
dotnet test StreamMark.slnx(Core 196, Avalonia 371); the publish run's native build, build-test (linux / macOS / windows) and NativeAOT smoke jobs all passed, 0 IL warnings.tools/cpu-bench.shwas run once but is not a valid measurement: the machine was heavily loaded (idle scenario 7.5% instead of 0.0%). The streaming hot path only gained O(1) work, but the benchmark should be re-run on a quiet machine and compared withdocs/benchmarks.md.MarkdownViewonly (notTranscriptView); find highlights are not recomputed afterRefreshMarkdown; precision is block-level.🤖 Generated with Claude Code
