CR: Tmux Config Evolution — Risk & Communications

Risk Assessment

Risk	Likelihood	Impact	Mitigation
Breaking existing keybindings	Medium	Medium	Test each change in isolation, per-phase commits enable surgical rollback
Plugin removal causing workflow regression	Low	Medium	Install tmux-thumbs before removing tmux-copycat in same commit
AsciiDoc docs diverging from markdown	Low	Low	Parallel only — markdown stays until user explicitly deprecates
tmux-thumbs Rust compilation failure	Low	Low	Fallback to tmux-fingers (Python) or skip replacement
