python-rich-table-column-overflow
Done. I diagnosed the bug in the real Chimera repo, applied the fix, verified it, and wrote the self-contained solution.
Deliverable: ~/chimera-rich-table-overflow-fix.md
src/chimera/cli/main.py's models() built one Rich column per category. The real catalog has 32 categories + 3 fixed = 36 columns, so at 80 cells Rich crushed every column to width 1 and dropped the model names entirely. formations() also dumped raw json.dumps(...) into table cells. The module console silently forced width 200 when piped, hiding the bug from tests while real TTYs (80 cols) broke.
