flick Architecture and Gesture Loop

**A fast iOS simulator agent with a dynamic, indexed action space.**

Give it one micro-goal. [TypeSafe's Jev](https://typesafe.ai) picks an operation and an element. The simulator executes via [Facebook idb](https://github.com/facebook/idb). Built as a sub-second "reflex layer" for parent coding agents (Codex, Claude Code) driving mobile UIs.

**593 ms per decision cycle.** Zero screenshots in the loop, 7× faster than frontier LLMs, with calibrated probabilities on every action.

The action space

Every observation produces a cleaned, indexed element table from the iOS accessibility tree:

[1] Button       General                  · uid=com.apple.settings.general
[2] Button       Accessibility            · uid=com.apple.settings.accessibility
[3] SearchField  Search                   · value=Search
[4] Switch       Airplane Mode            · value=0
...

The operations are `TAP`, `TYPE_TEXT`, `SCROLL_UP`, `SCROLL_DOWN`, `WAIT`, `DISMISS_MODAL`, `DONE`, and `BLOCKED`. Only valid operations and targets are offered.
