Fix Gradio mobile layout and add evaluation export pipeline

Fix mobile responsiveness of a Gradio app (Homeroom Copilot) without touching the desktop layout, then add a separate evaluation export framework for AI-generated action plans without modifying existing pipeline logic.
- +0Prompt · +0Fix mobile responsiveness: desktop layout must stay exactly the same, but on screens below 768px switch to single-column stacked layout, remove horizontal scrolling, fix text clipping, preserve all functionality.
- +0mAgent did · +0mInvestigated app.py CSS and Gradio Row/Column structure, identified fixed 840px panel heights and overflow:hidden causing mobile squeeze, added mobile-only CSS override under @media (max-width: 767px) to stack rows/columns and remove fixed heights.
- +1mAgent did · +1mRan syntax check (passed), then tried to start local Gradio server to visually verify the fix but hit missing 'spaces' package from ZeroGPU deployment work.
- +1mFail · +1mLocal venv also missing torch/transformers, so the app can't be launched locally to verify visually.
- +2mAgent did · +2mBuilt local no-op shims for spaces/torch/transformers modules to launch the app for visual-only verification, working through several PowerShell quoting failures before getting the shimmed server running on port 7861.
- +4mAgent did · +4mUsed a browser automation tool to measure viewport vs scroll width at iPhone size (375px, no overflow) and desktop size (1280px, panels still side-by-side), confirming the fix worked in both cases.
- +5mAgent did · +5mStopped the shimmed verification server so it wouldn't be mistaken for a real deployment, and summarized the CSS root causes fixed (fixed heights, overflow:hidden, missing full-width mobile rules).
- Break · 1h 04m away, not counted
- +5mPrompt · +5mAdd an evaluation export framework: a button to generate 8 evaluation cases (2 each of low/moderate/high/critical risk) exported as markdown, JSON, and a human evaluation CSV template, without modifying any existing risk/root-cause/retrieval/action-plan logic.
- +5mAgent did · +5mExplored app.py's student/risk data functions, added an isolated evaluation exporter (case selection across risk tiers, markdown/JSON/CSV export) and a standalone evaluation_summary.py script, wired a new 'Export Evaluation Dataset' button into the existing Advanced Options accordion.
- +12mOutcome · +12mSyntax checks passed on app.py and evaluation/evaluation_summary.py; mobile layout confirmed with no horizontal overflow at 375px width and desktop unchanged at 1280px; new evaluation export button writes 8 case files, a JSON dataset, and a CSV template to evaluation/.
I'd start by telling the agent upfront that the local venv is missing deployment-only packages (torch, transformers, spaces) so it doesn't waste time discovering that itself. The shimmed local server it built to verify the mobile CSS fix was the right call and actually proved the fix worked at both 375px and 1280px viewports. For the second task, being explicit that this was purely additive (no touching risk/root-cause/action-plan logic) kept the agent from overreaching into the core pipeline.
