Streaming and committed markdown list rendering can diverge

[Juliusolsson05]

Problem

A saved debug note reports weird bullet/list rendering, but the captured HTML contains valid list DOM. This points to visual styling or streaming-vs-committed markdown differences rather than markdown parse failure.

Evidence

Bundle:

~/.config/agent-code/debug-bundles/manual/2026-06-14T13-59-16-931-4757ae44

• Note reports weird bullet/list rendering.
• html-clean.html contains valid <ol> / <li> structure for the visible numbered list.

Suspected Paths

• Streaming markdown uses remarkGfm plus remarkBreaks.
• Committed markdown uses GFM through Prose.
• .prose-theme manually restores list styles and indentation.

Relevant paths:

• src/renderer/src/features/feed/lib/remark-plugins.ts
• src/renderer/src/features/feed/ui/markdown/Prose.tsx
• src/renderer/src/styles.css

Expected

Streaming and committed prose should render list indentation and markers consistently. If the original weirdness was raw compaction XML being rendered as markdown, fixing compaction tagging may resolve part of this symptom.

Lightly linking this to #172. The new rendering engine may reduce streaming-vs-committed markdown divergence if both paths share the same typed row/render surface, but this issue may still be pure markdown/style parity.

After #172 lands, re-test this bundle. If list DOM is still valid but visual output differs, keep this as a focused markdown/CSS issue rather than a feed ownership issue.
