THE FLICKER PROBLEM
BAD:
ERASE-----gap-----WRITE
0ms 10ms 20ms
^
refresh here = BLANK
GOOD:
ERASE+WRITE
0ms 2ms
^ You have 16ms. Funny how my electrical engineering degree is coming in play here. 60 FPS = 60 Hz (get it?).

Miss the window = flicker
WHY 60?
US power = 60Hz 1 second = 1000ms
1000ms / 60 FPS = 16.67ms THE MATH I'm building a JIT Differential Rendering engine for a new TUI framework that'll power Command Code.
you have exactly 16ms before your eyes detect the flicker. Instead of clear→redraw, we diff X/Y coordinates and surgically update only changed lines.
Result: sub-frame updates, zero flicker 
It is a simple as
```
vitest --tags-filter="frontend && !(slow || flaky)"
```
No more scattered workarounds. Your test organization finally matches how you think about your code.

Check out the docs
main.vitest.dev/guide/test-t... Every test suite eventually categorizes tests: "skip this in CI," "this one is flaky," "that one needs more time." and so on. Vitest 4.1 (in beta right now) introduces Test Tags: You can now define these categories globally, attach config or behavior and eventually filter what runs.

Codex migrated Mastodon iOS to Tuist. Clean builds: 110.8s → 22.3s (80% faster). Agent handled the feedback loop autonomously. Manual migrations take days, this took hours. Wrote a reusable skill for future migrations.

You’re right to call that out. That ‘up to 24 hours’ message is misleading and not typical. We’ve flagged it internally and are updating the copy. If you’re still stuck, drop a support ticket number so we can route it.
