Analysis

This is a ProseMirror schema validation error. The Tiptap listItem node (from StarterKit) has a content spec of "paragraph block*", meaning the first child must be a paragraph, optionally followed by other block nodes. A heading node as a direct child of listItem (especially as the first child) violates this constraint.

Root Cause

The LLM generated markdown where headings appear inside list items (e.g. - # Control gates represent custom innovation... or similar nested structure). When this markdown is converted to Tiptap JSON via md2json(), it produces a listItem containing a heading node, which is invalid per the schema.

How the content flows

1. LLM generates markdown — The enhance workflow (enhance-workflow.ts) streams markdown from the LLM
2. Markdown → JSON conversion — On completion, enhance-success.ts calls md2json(text) (from packages/tiptap/src/shared/utils.ts) which uses @tiptap/markdown's MarkdownManager.parse() to convert to Tiptap JSON
3. JSON stored — The result is stored as enhanced_notes.content via store.setPartialRow()
4. Editor renders — EnhancedEditor (session/components/note-input/enhanced/editor.tsx) reads the content via parseJsonContent() and passes it as initialContent to the Tiptap editor
5. Schema validation fails — ProseMirror's nodeFromJSON() calls checkContent() which throws "Invalid content for node listItem: <heading(...")

Key Files

File	Role
packages/tiptap/src/shared/utils.ts	md2json() — converts LLM markdown output to Tiptap JSON
packages/tiptap/src/shared/extensions/index.ts	Schema definition — StarterKit with heading levels 1-6, listKeymap disabled
apps/desktop/src/store/zustand/ai-task/task-configs/enhance-success.ts	Calls md2json() on LLM output and stores result
apps/desktop/src/session/components/note-input/enhanced/editor.tsx	Reads stored content and renders it in the Tiptap editor
apps/desktop/src/store/zustand/ai-task/task-configs/enhance-validator.ts	Early validator — checks for # prefix but doesn't validate nested structure

Potential Approaches

1. Sanitize md2json() output — Add a post-processing step in md2json() (in utils.ts, similar to the existing sanitizeMarks()) that walks the JSON tree and converts any heading nodes found inside listItem nodes into paragraph nodes with bold text (or just paragraphs). This is the most defensive approach.

2. Wrap editor content loading — In EnhancedEditor or parseJsonContent(), validate the JSON against the schema before passing to the editor (using the existing validateJsonContent() from schema-validation.ts), and if invalid, fall back to EMPTY_TIPTAP_DOC or attempt sanitization.

3. Prompt engineering — Adjust the enhance system prompt (rendered via templateCommands.render()) to explicitly instruct the LLM not to use headings inside list items. This reduces frequency but won't eliminate the issue.

4. Extend the listItem content spec — Modify the schema to allow headings in list items (e.g. "(paragraph | heading) block*"). This is risky as it changes the schema contract and may have knock-on effects.

Recommended: Option 1 (sanitize in md2json()) combined with Option 2 (validate before rendering) for defense in depth. The sanitizeMarks() function in utils.ts already shows the pattern for post-processing md2json() output.

Stack Trace Context

The undo-delete-D7wCGZIq.js filename in the stack trace is a Vite chunk hash — it bundles ProseMirror model code (checkContent, check) alongside other modules. The actual crash is in ProseMirror's node content validation, triggered during a React useEffect when the editor initializes with the invalid content.
