Migration: v0.16 → v0.17

v0.17 focuses on Protégé shell parity: menus, toolbars, dialogs, keyboard workflows, webview tab persistence, and named perspectives.

What changed

Command system

  • OntoCode registers a centralized command registry with enablement predicates (ontocode:hasOntology, ontocode:isDirty, ontocode:hasSelection, ontocode:reasonerRunning, …).
  • LSP exposes ontocore/listCommands, ontocore/getWorkspaceUiState, and dialog schemas for validated flows.
  • Catalog stats are available on getCatalogSnapshot (not only after index).
  • File / Edit / Active Ontology / Refactor / Reasoner / Tools / Window / Help menus surface every high-level OntoCode action.
  • Toolbar buttons for New, Save, Undo/Redo, Search, Reasoner Sync, Preferences, Metrics.
  • Default keybindings from the keyboard shortcuts catalog; conflict detection runs at activation.

Dialogs

  • Structured dialogs replace many InputBox/QuickPick flows: New Ontology, Export, Prefix Manager, Ontology Metadata, Create Entity, Delete (with impact), Search, Metrics, Reasoner Settings, Preferences hub.
  • Critical dialogs validate IRIs/prefixes/imports live and refuse invalid persistence.

Engine

  • Prefix and ontology-metadata patch ops; create-ontology scaffold; export/convert; active ontology state; merge/replace entity refactors.
  • Reasoner menu actions (Start / Synchronize / Classify / Consistency) all run the same classify path via runReasoner. Stop Reasoner clears UI running state only — an in-flight LSP request cannot be cancelled.

Layout

  • Panel serializers keep OntoCode webview tabs across VS Code reloads; transient entity/query/refactor payload is not restored (panels show a recovery message — reopen from commands).
  • Named perspectives: Modeling, Reasoning, Review (save / switch / reset) open the associated panel set.

Help

  • About, Plugin Info, Error Log, Diagnostic Export, and documentation links.

Breaking changes

None known in v0.17.0. New LSP methods are additive.
