v0.9.2: GUI polish -- example dropdown, spinners, JSON+PDF download - #3
Merged
Conversation
Polish pass on the existing app/streamlit_app.py (not a rewrite); improve in place, no duplicated features. kernel_viewer core + its output untouched. - Example loader: it already auto-listed examples/*.npz (the spec's "hardcoded" assumption did not hold), so this just relocates it to a sidebar "Load Example Dataset" selectbox + button; the uploader stays in the main area. No second loader added. - st.spinner on the genuinely slow steps (load / classify / dashboard render / stateflow), with plain honest messages -- 4D classification is slow. - New "Download results" area: JSON reuses kernel_viewer.io.saver.save_report (single source of truth, not hand-serialized) and a one-page PDF of the SAME dashboard Figure already shown (matplotlib's own pdf backend; no new dep, no multi-page assembly). Both exposed as importable helpers report_json_bytes / dashboard_pdf_bytes so the headless smoke test can reach them. - New paths (example load, exports) stay inside the existing st.error handling. - Version -> 0.9.2. Verified: headless GUI smoke (AppTest) passes; JSON has regime/coherence/ exponent/features/notes; PDF starts with %PDF; both core suites green and kernel-viewer output byte-identical.
