- [ ] We should probably rename the Kill <Process> terminology to Close <Process> instead, across processes and agents.
- [ ] Exited shells are still being treated as active processes. They should be removed from the process list when they exit.
- [ ] Shells should be renamed to terminals. "New Terminal" etc.


# On Hold
- [ ] There's a unicode <?> being displayed in opencode [ON HOLD]
  - Investigated 2026-05-14: patterm passes ghostty grapheme codepoints
    through unchanged (vt/ghostty.go:452-462), so the `<?>` glyph is
    most likely the *host* terminal's font fallback for opencode's
    Nerd Font private-use codepoints, not a patterm substitution.
    Need a concrete reproduction (which codepoint, which host
    terminal/font) before changing rendering.
- [ ] After codex rips for like 15 minutes, the terminal becomes quite slow. [ON HOLD / VERIFYING]
  - 2026-05-14: Perf plan P1-P11 landed (see CHANGELOG). Needs a real
    long-running codex session to confirm whether the steady-state
    slowdown is gone or some hotspot remains. Capture a pprof if it
    still feels slow after ≥15 minutes — the structural drivers the
    audit named are all addressed, so a remaining symptom is a new
    one and probably wants fresh profiling.
