COMET v0.4.0

Added

• Obsidian-compatible callouts with custom titles, fold states, nested content,
  and compact GitHub-inspired presentation in the Milkdown note surface.
• Obsidian-style typed Properties controls for text, lists, numbers,
  checkboxes, dates, date-times, tags, and property links, with COMET-styled
  type selection, inline list editing and removal, Vault tag suggestions, and
  Properties undo and redo shortcuts.

Changed

• Replaced the Atomic／full-page CodeMirror note surface with Milkdown Crepe
  components for one shared reading and editing document.
• Isolated Codex host integration and Node.js runtime adapters into
  @comet/codex and @comet/runtime, keeping the MCP, Core, Task, Graph, and
  Markdown packages host-neutral.
• Unified active Milkdown editing controls with COMET interface typography and
  sizing, and added Callout to Crepe's existing slash menu.
• Unified Vault metadata, Graph links, Task metadata, and link integrity on the
  @comet/markdown remark AST projection and Obsidian wikilink extension.

Fixed

• Fixed Milkdown code block copy actions in MCP Apps hosts that reject iframe
  Clipboard API access, and aligned the Copy button with COMET control tokens.

Removed

• Removed the legacy markdown-it renderer, Obsidian renderer plugins, and
  duplicate regex-based Markdown link parser.

COMET v0.3.0

Added

• Native macOS directory picker for opening an existing Vault or selecting the
  parent directory for a new Vault.
• Properties-backed TODO board with todo, in-progress, and done columns,
  Markdown task creation, cross-column status updates, and card navigation to
  the existing note view.
• Explorer file and directory operations with inline rename, drag and drop,
  keyboard shortcuts, context menus, clipboard actions, and one-step undo for
  reversible COMET operations.
• Bundled obsidian-markdown agent guidance for Obsidian properties,
  wikilinks, embeds, and callouts. The complete upstream skill collection is
  tracked as the skills/obsidian-skills Git submodule at a pinned revision,
  while unsupported skills remain inactive.

Changed

• Resource creation now accepts typed frontmatter values such as tag arrays
  and merges them consistently with the configured new-note template.
• Task domain logic, board UI, styles, and tests now live behind the dedicated
  @comet/task package boundary instead of changing COMET core internals.
• Knowledge graph projection, visualization UI, styles, and tests now live
  behind the dedicated @comet/graph package boundary.
• Task cards reuse the existing Markdown Properties presentation instead of a
  separate task-only field renderer.
• Task board columns use the concise English labels To Do, In Progress,
  Done, and Unclassified.
• Markdown titles and Explorer rows now use the same move operation when
  renaming notes.

Fixed

• Removed resources are moved to the operating system trash instead of a
  Vault-local folder, with the trash runtime dependency packaged intact.
• Explorer accepts both Delete and the Backspace value emitted by the
  physical Delete key on macOS.
• Renaming a note now updates Explorer, Task, and Graph snapshots together,
  removes the old graph node, and rewrites matching wikilinks and Markdown
  links to the new path.
