The contenteditable + CodeJar + Prism approach (Tasks 1-12 + 4 smoke
fixes shipped this session) hit too many contenteditable edge cases to
ship:
- Copy collapses multi-line selections to one line (Selection.toString()
doesn't reliably reconstruct newlines across Prism's tokenized <span>
topology).
- Enter sometimes requires two presses + cursor color shifts (caret
lands "between" sibling tokenized spans; first Enter shifts it into
a real text node, second actually inserts).
- Cascade of earlier bugs already fixed (cursor jumped to start, then
end; popup-accepted-quote duplicated; popup didn't accept at
end-of-line) were all symptoms of the same root cause: manual Range
API manipulation against tokenized contenteditable DOM is unreliable.
Exiting the sunk-cost path before more fixes accrue. The next attempt
will be a fresh brainstorming session weighing CodeMirror 6 (battle-
tested, accepts a one-time bundler step) vs textarea-overlay (real
<textarea> for editing, passive <pre> highlight, no contenteditable).
Kept (informs the next attempt):
- spec + plan documents in docs/superpowers/
- Playwright scaffolding (conftest + smoke test) + dev deps + e2e marker
- scripts/dev-server.py (independent of editor approach)
- AGENTS.md sandbox + Chromium Mach-port notes
Removed:
- editor JS (editor.js, srccfg-grammar.js)
- editor CSS (editor.css)
- vendored CodeJar + Prism + README
- srccfg vocab data
- editor partial (_editor_assets.html)
- template wiring (data-editor-language attributes, asset partial includes,
files-editor language <select>)
- files-overlay.js editor bridge (setEditorContent helper, dropdown
listener, filename-handler auto-redetect, dropdown reset)
- tokens.css syntax-color additions (dead without the editor)
- form-contract tests in test_blueprints.py + test_script_overlay_routes.py
- the editor-specific Playwright test (test_editor.py)
- create-blueprint modal trim that was tied to editor UX (Arguments +
Config textareas restored)
