Changelog

Implements document-like selection across block boundaries in the block

editor. Double-tap Cmd+A selects all blocks (first tap selects within

the focused block, second escalates to all blocks). Shift+Click extends

selection from the anchor block to the clicked block. Selected blocks

receive a visual highlight overlay via the block-cross-selected CSS class.

Cmd+C copies aggregated text from selected blocks separated by blank

lines. Cmd+X copies and deletes. Delete/Backspace removes selected

blocks. Escape or clicking into a single block clears the selection.

Typing any character also dismisses the selection.

State is managed via CrossBlockSelection record on NotesViewModel with a

static event that BlockWrapper instances subscribe to for highlight

updates. No SDK or UI.Adaptive changes required.

When a dataset chart query fails with a binder or aggregation error,

the loader now sends a ChartQueryErrorMessage to the shell's

DatasetInsightOrchestrator for AI-assisted correction. The AI returns

a fixed chart config which is retried once. Recovery has a 15-second

timeout and only attempts one retry to prevent infinite loops.

Notes plugin version bump to 1.56.0.

Add ChartQueryErrorMessage to SDK for cross-boundary error recovery

communication. When a chart's dataset query fails (e.g., missing

aggregation on GROUP BY), the orchestrator receives the error context,

sends it to the AI for a corrected chart config, and retries once.

Add intermediate progress updates to the insight generation pipeline

so users see status at each stage: sending to AI, processing response,

generating chart datasets, and saving to Notes.

SDK version bump to 1.59.0 for new message type.

Flatten sidebar item styling (smaller icons, tighter margins) to match

Notes' minimal aesthetic. Add hover-reveal (x) delete buttons on Views

and AI Generated list items. Extract delete logic into partial class

DataViewModel.Delete.cs with async reference search — on delete request,

the overlay now checks for cross-plugin entities referencing the dataset

via SDK SearchAsync and displays clickable navigation links before

confirming. Add DatasetReference model, wire IPrivStackSdk through

DataPlugin. Bump version to 1.20.0.

Integrate the 3D embedding space visualization as a second tab in the

Graph plugin. New EmbeddingDataService calls the rag_fetch_all FFI,

projects 768-dim embeddings to 3D via random projection, and computes

pairwise cosine similarity edges above a configurable threshold.

EmbeddingSpaceViewModel manages loading, parameters (similarity threshold,

max points, max neighbors, auto-rotate), entity type filtering, and

selection state. GraphViewModel gains GraphTab enum and ActiveTab property.

GraphView.axaml adds a tab strip with Knowledge Graph / Embedding Space

tabs, per-tab sidebar controls, and per-tab footer stats. GraphView

code-behind handles tab switching with lazy control creation.

GraphPlugin version bumped to 1.1.0, Desktop to 1.58.0.
