Rainbow is putting its code in order — and the cleanup shows what is coming

Three changes landed in the main branch over the past few days, and all three delete more lines than they add. On its own that means little. What is interesting is something else: two of them are named sports-01 and sports-02.

What exactly was fixed

• #7848, nested button presses on Android. 86 files, −976 lines. A button inside a button did not work on Android, and feature code had to compensate for it in every single place. It was fixed in native code: a patch to the gesture handler, a 367-line patch to the library. Behaviour now matches iOS. Dead components and the old context-menu implementations went out along the way.

• #7849, rendering. Drawings vanished when a view on iOS was detached and reattached. Fractional canvas dimensions were truncated to whole points. Cards on Android briefly rendered without their shadows. Plus a missed "image loaded" callback was fixed: it is now deferred so the app can subscribe before it fires.

• #7866, colours in the design system. A duplicate border component was removed — there were two with the same name. But the more important part is narrowing what worklets capture.

Worklets are worth explaining. They are pieces of code run on a separate rendering thread so animations stay smooth. Everything such a piece captures from its surroundings has to be carried across threads. Previously the entire palette went in — background colours as well as text colours, when only the latter were needed. Now exactly what is required is carried.

And now what all of it is for

The branches are called sports-01 and sports-02. Behind them stands a series of thirteen PRs, and the titles give the plan away:

• sports-04 — betting straight from match cards through Polymarket
• sports-08 — replace the current predictions list with a sports one
• sports-09 — replace King of the Hill with a Sports tab
• sports-11…13 — three separate PRs of tests

Sports already works in the wallet — inside the Polymarket section, which covers CS2, MLB, NBA, NFL, NHL, soccer, UFC and other leagues. The series does not create it from scratch; it rebuilds it and promotes it to its own tab in the bottom bar.

How close is this. Two of the thirteen are merged, and both are groundwork: presses and rendering. There is no sports directory in the main branch at all yet, and no flag either. The section it is meant to replace is already switched off: king_of_the_hill_enabled sits at false, the slot is free.

No timeline can be given — eleven PRs are open, and some branches at Rainbow never reach a release. But the order of work says something: two PRs fix the platform first, then data, then the interface, and only then three PRs of tests. Nobody does that for something they plan to throw away.
