feat(explorer): add Ontology Hub workspace — Registry, Loader, Entity Search & SKOS ( closes #518 )
...
Implements the first subissue of Ontology Hub (#517 ):
Frontend:
- New OntologyWorkspace with 6 tabs (Registry, Editor, Versions,
Alignments, Health, SHACL); active tab persisted in ontologyTab URL param
- OntologyManager: full registry CRUD with status/format badges, stats,
toggle/refresh/remove actions, search + filter toolbar, empty state CTA
- OntologyLoader: 3-tab modal — URL import with live preview, drag-and-drop
file upload, and Create New (from scratch / data / text)
- OntologySearch: debounced entity search with type filters and detail panel
showing superclasses, subclasses, domain/range, instance count
- SKOSVocabularyManager: recursive concept hierarchy tree, client-side
filtering, full SKOS annotation + relation detail panel
- Editor/Versions (subissue 2) and Alignments/Health/SHACL (subissue 3)
tabs render descriptive stub cards as placeholders
Backend:
- 12 new FastAPI endpoints under /api/ontology (registry, preview, load,
create, search, entity detail, SKOS schemes + concept detail, toggle,
refresh, remove)
- rdflib-based RDF parser supporting Turtle, RDF/XML, N-Triples, JSON-LD
- URL fetching via requests in asyncio.to_thread with 20 MB cap
- Registry stored in app.state.ontology_registry; route ordering prevents
literal paths being shadowed by /{uri:path} wildcards
Also: add playwright dev dependency for screenshot testing

feat(explorer): add Semantica Knowledge Explorer UI with full feature set
...
## Folder & Project
- Renamed `semantica-explorer/` → `explorer/` (cleaner path)
- Browser tab title: `Semantica Knowledge Explorer`
- Brand pill: `SEM` → `SKE` (tooltip: Semantica Knowledge Explorer)
- Nav rail label: `Explore` → `Knowledge Explorer`
- package.json name: `semantica-knowledge-explorer`
- Downgraded Vite 8 → Vite 5 for Node v20.17.0 compatibility
## App Shell
- Dynamic per-workspace kicker labels replacing static "Workspace" pill:
Graph Studio · Vocabulary Browser · Reasoning Engine · SPARQL Query ·
Decision Intelligence · Knowledge Audit · Graph Governance
## Enrich Workspace — 2 new tabs
### Entity Resolution tab
- Similarity threshold slider (0.50–0.99)
- Run Dedup Scan → POST /api/enrich/dedup
- Flagged pairs list with colour-coded score bars (red/amber/green)
- Expandable inline diff: primary vs duplicate side-by-side
- One-click Merge → POST /api/enrich/merge with logEvent dispatch
- Dismiss per pair; Clear all button
- Merge history sidebar pulled live from Registry store
### Registry tab (Document Registry)
- Live chronological audit log of all KG mutations in-session
- Colour-coded op-type badges: IMPORT · MERGE · ADD NODE · ADD EDGE ·
INFER · DELETE · EXPORT · VOCAB
- Filter pills to narrow by operation type
- Expandable JSON detail rows per entry
- Clear log button
- Entirely client-side via registryStore (no backend needed)
## Manage Workspace — 2 new tabs
### KG Overview tab
- Stats chips: total nodes, edges, graph density
- Node type breakdown bar chart (up to 8 types, colour-coded)
- Edge type breakdown bar chart from /api/graph/stats
- Top-10 most connected nodes ranked by degree
- Skeleton loading states + Refresh button
### Ontology Summary tab
- Read-only SKOS scheme tree (scheme → top concepts → narrower)
- Concept detail panel: labels, notation, description, narrower nav
- "Open Full Browser" button deep-links to Vocabulary Browser tab
## Decision Workspace polish
- CausalFlowDiagram: vertical node cards connected by relationship pills
- Outcome badges: colour-coded (green=approved, red=rejected, amber=deferred)
- Live filter input across decision ID, category, and outcome
- Animated skeleton loading while list fetches
## Graph Inspector polish
- PathFlowViz: clickable node chips connected by edge-type labels;
clicking a chip focuses that node in the canvas
- Link Prediction button shows spinner while computing
- Empty states for path trace and candidate links sections
## Registry dispatch — WebSocket
- ADD_NODE events → logEvent("add-node", …) in GraphWorkspace WS handler
- ADD_EDGE events → logEvent("add-edge", …) in GraphWorkspace WS handler
- Import, Export, Merge already dispatched logEvent on API response
## Graph visibility overhaul
### Edge colours (were nearly transparent, now clearly visible)
- edgeBackbone: rgba(…, 0.04) → rgba(…, 0.38)
- edgeStructure: rgba(…, 0.009) → rgba(…, 0.28)
- edgeInspection: rgba(…, 0.026) → rgba(…, 0.48)
- Muted edges: 0.009–0.02 → 0.12–0.26
- Focus edges: 0.16 → 0.42
### Edge sizes
- default minSize: 0.18 → 0.9 (always at least 1 pixel wide)
- path minSize: 1.8 → 2.4
- inactive/muted: hide:true → hide:false (dimmed not hidden)
### Node sizes
- default sizeMultiplier: 0.72 → 0.92
- default minSize: 0.68 → 3.5 (visible at all zoom levels)
- overview nodeScale: 0.66 → 0.88
- nodeTintMix (colour): 0.03 → 0.14
- nodeCoreMix (brightness): 0.52 → 0.72
### Label budget
- overview: 10 → 28 labels
- structure: 36 → 60 labels
- inspection: 80 → 120 labels
### Sigma settings
- renderEdgeLabels: false → true (relationship type on every edge)
- edgeLabelSize: — → 10
- labelRenderedSizeThreshold: 4 → 2
- labelDensity: 0.86 → 1.1
- hideLabelsOnMove: true → false (labels stay visible while panning)
- hideEdgesOnMove: true → false (edges stay visible while panning)
- minCameraRatio: — → 0.04 (prevents zooming inside a node)
- maxCameraRatio: — → 8 (graph stays visible when zoomed out)
### Zoom controls
- Added Zoom In (+) and Zoom Out (−) buttons to graph toolbar
- Smooth animated zoom via camera.animatedZoom / animatedUnzoom (200ms)
- Mouse scroll wheel clamped between minCameraRatio and maxCameraRatio
