app/ui/analysis_screen.py

"""Screen 5: Analysis.

Shows the fit assessment as a set of clean cards — verdict, score,
strengths, concerns, connects guidance, and the best proposal angle. All
API work happens in the services; this screen only reads their results
and renders them.

The analysis is keyed on the current opportunity's job fingerprint. When
the confirmed job details change (a new screenshot, edited fields) the
fingerprint changes and the match / score / recommendation are
regenerated, so a previous opportunity's scores can never carry over. A
"Re-run Analysis" button forces a fresh pass for the same opportunity.

Provider/model labels, task names, prompt sizes, the job fingerprint,
evidence IDs, and raw error text are hidden unless ``SHOW_DEBUG_PANEL=true``.
