Node selection only worked through the canvas click handler, but
onTouchStart calls preventDefault() to stop page scroll/zoom, which
also suppresses the browser-synthesized click. A single-finger touch
went straight into panning, so on phones and tablets tapping a node
did nothing: no selection, no popover, no way to open a document from
the graph.
Detect taps from the raw touch lifecycle instead: remember where the
single-finger touch started, cancel the tap once the finger moves more
than 10px or a second finger lands, and on release hit-test the start
point through the viewport transform and forward the result to
onNodeClick. Tapping empty space clears the selection, matching mouse
behaviour.
Covered with unit tests driving the handler through a stub canvas:
tap on node, tap on empty space, jitter within the slop threshold,
pan, pinch, and a tap through a zoomed/panned viewport.
## Summary
Addresses user feedback about the graph view: content in node popovers was hard-truncated at 100 characters with no way to read the full text or navigate to the document.
### Changes
**Scrollable popover content (no more truncation)**
- Removed the `truncate(content, 100)` call -- full content is now rendered in the popover
- Made the content area scrollable with `maxHeight: 100px` and `overflowY: auto`
- Increased version timeline entry truncation from 60 to 120 characters
- Increased version timeline container height from 120px to 160px
**"View document" in shortcuts panel**
- Added an eye icon + "View document" entry to the shortcuts panel (alongside existing arrow navigation)
- Clicking opens the Document Modal for the corresponding document
- Works for both document nodes (opens that document) and memory nodes (opens the parent document)
- Popover is automatically dismissed before the modal opens (prevents z-index overlap)
- Wired `onOpenDocument` callback through the full component chain: `page.tsx` -> `GraphLayoutView` -> `MemoryGraph` wrapper -> `MemoryGraphBase` -> `NodeHoverPopover`
**Shortcuts panel visual cleanup**
- Icon badges (`KeyBadge`) retain dark background and border for a keyboard-key badge look
- All icons (including the new EyeIcon) are uniformly wrapped in `KeyBadge` for consistent styling
- Removed background, border, and border-radius from the shortcuts panel container itself
- Widened shortcuts panel from 100px to 160px so navigation labels are fully visible
**Type safety improvement**
- Changed `MemoryGraphProps.colors` from `GraphThemeColors` to `Partial<GraphThemeColors>` to match actual usage (callers pass partial overrides that get merged with defaults)
- Replaced `as Partial<typeof import(...)>` cast with proper `satisfies Partial<GraphThemeColors>` using a direct type import
### Files changed
- `packages/memory-graph/src/components/node-hover-popover.tsx` -- scrollable content, EyeIcon + "View document" in shortcuts, KeyBadge styling, NavButton icon type broadened to `React.ReactNode`, all icons wrapped in KeyBadge
- `packages/memory-graph/src/components/memory-graph.tsx` -- popover dismissal wrapper (`handleOpenDocument`), prop forwarding
- `packages/memory-graph/src/types.ts` -- `onOpenDocument` prop on `MemoryGraphProps`, `colors` changed to `Partial<GraphThemeColors>`
- `apps/web/components/graph-layout-view.tsx` -- accepts and passes `onOpenDocument`
- `apps/web/components/memory-graph/memory-graph-wrapper.tsx` -- `onOpenDocument` in wrapper props, clean type import
- `apps/web/app/(app)/page.tsx` -- `handleOpenDocumentById` handler, wired to `GraphLayoutView`
## Testing
### Unit Tests (154/154 passed)
- **Command:** `cd packages/memory-graph && bun run test`
- **Result:** 9 test files, 154 tests passed (107 existing + 47 new)
- **New test file:** `packages/memory-graph/src/__tests__/node-hover-popover.test.tsx` covering:
- Layout constants (`SHORTCUTS_W=160`, `CARD_W=280`, `TOTAL_W` formula)
- Content area scrollability (`maxHeight:100`, `overflowY:auto`, `flex:1 1 auto`, no truncation)
- KeyBadge styles (has `backgroundColor: colors.controlBg`, has `border` with `colors.controlBorder`)
- Shortcuts panel styles (no `backgroundColor`, no `border`, no `borderRadius`)
- EyeIcon SVG component (`aria-hidden`, viewBox, path, circle, stroke)
- "View document" button render guard (`onOpenDocument && documentId`)
- `documentId` derivation (memory vs document node)
- VersionTimeline truncation limit (120 chars) and container maxHeight (160)
- `onOpenDocument` prop wiring
- NavButton icon prop type (`React.ReactNode`), all icons wrapped in KeyBadge
- `handleOpenDocument` wrapper in MemoryGraph (dismiss calls, ordering, useCallback deps)
### Build
- **Command:** `bun run --filter=@supermemory/memory-graph build`
- **Result:** Build succeeds, 0 errors
### Lint/Format
- **Command:** `bunx biome ci --changed --since=origin/main --no-errors-on-unmatched`
- **Result:** 6 files checked, no fixes applied, 0 errors
### Type Checking
- `packages/memory-graph`: 0 errors
- `apps/web`: 0 new errors introduced
### CI
- "CI - Type Check, Format & Lint" workflow passes
- "Claude Code Review" workflow fails due to repo config (`non-human actor: vorflux` not in `allowed_bots` list) -- not related to code changes

add lot of modifications
fix few things
- Switch to infinite query with viewport-triggered pagination (loads more when user zooms out 3x past node bounds)
- Remove maxNodes cap so all data renders
- Remove background color and dot pattern from graph
- Make document-memory edges light grey

## Summary
- Fixed memory graph stuck on "Loading graph data..." caused by field name mismatch after package rewrite (`memoryEntries` vs `memories`, `type` vs `documentType`)
- Improved MCP app UI to match console-v2 design: golden derives edges (#FBBF24), edge glow pass, node hover effects, dot mode at low zoom, vertical controls with keyboard shortcuts, expandable legend
- Synced local `memory-graph` edgeDerives constant with published npm version
## Test plan
- [ ] Run `cd apps/mcp && bun run dev`, connect via Claude Desktop
- [ ] Verify graph renders with golden derives edges and blue dashed extends edges
- [ ] Verify node hover/selection glow effects
- [ ] Verify Fit (Z), Center (C), zoom (+/-) keyboard shortcuts
- [ ] Verify legend expands/collapses
