Summary

Quick edits to a project's instruction and notes files from the dashboard project view, plus a header regroup. Plan: plans/062-markdown-editor.md. PHASE 62 ACCEPTED 2026-10-10.

• Overview | Markdown toggle beside the project title. The header stays in both views and only the body swaps. Session actions (Continue control, New session tab) sit top-right; housekeeping (Copy update, Pin, Archive) is on the path row.
• File list: CLAUDE.md, AGENTS.md, .claude/CLAUDE.md, .logic-loop/board.md first, then root *.md, then docs/*.md (one level). Files over 1 MB and symlinks pointing outside the project are excluded.
• Editor: plain textarea with a syntax-colour layer behind it (headings by level, list markers, bold, code, links, @imports, fences, quotes, rules). ⌘S saves. Open in editor (Plan 061) sits beside the filename. Agent memory files carry a note that running agents pick up edits on /clear, /compact or a new session.
• Unsaved drafts are kept in memory (marked ●) when you switch files or tabs, instead of a discard prompt that can't catch leaving via a terminal tab. Quitting the app drops them.

Safety

• md_read / md_write accept a name only if it's in a fresh md_list result, then re-check it with pty::resolve_inside, so callers can't reach ../, nested or absolute paths.
• Saves are compare-and-swap against the exact text loaded. If the file changed on disk (e.g. an agent edited it), a banner offers Reload or Overwrite; nothing is clobbered silently. There is a small TOCTOU window between the compare and the write; accepted, and commented in the code.
• No preview: file content is only ever React text, never HTML (invariant 5).
• CRLF files round-trip byte for byte. UTF-8 only.

Verification

• cargo test --lib: 185 passed, 1 ignored (5 new in markdown.rs: list order/exclusions, outside symlink, unlisted/path names, CAS, non-UTF-8/oversize)
• npm run check (new markdown-editor:check: CRLF round-trip and highlighter alignment), npm run opencode:check, npx tsc --noEmit, npm run build, cargo clippy --all-targets -- -D warnings, git diff --check
• Built-app checks 111–120 passed (Codex computer use, plus maintainer confirmation of the /clear reload in 116). Results in docs/TESTING.md.

Not verified: Windows (CRLF default, editor launch); tracked in the ROADMAP Windows gap table.

Also in this PR: IDEAS entry "Half 1c" (diff pop-out falls back to unstaged changes), found during testing. Not implemented.
