Gateway

The culture wheel

The first workspace screen is a locked wheel of the eight POCA apps (ollin, amoxtli, tlato, tlalli, cuilo, cualli, metztli, teo). Its center pattern comes from the PAC:

• Query. /wheel/active on org.poca.pac.identity, reading a single column: wheel_pattern_uri.
• Validate. The returned URI must be content:// on the identity authority; anything else is refused, so a spoofed provider cannot inject a file path.
• Render. The pattern streams through the provider and decodes as a bitmap (png, webp, or jpeg); failures fall back to no pattern. Reloaded on launch and on resume.

Feed overlay

Gateway binds its feed overlay (the swipe-left panel) directly to PAC Reader (org.poca.pac) through the standard launcher overlay protocol, and registers it as the first-priority, unconditionally trusted feed bridge. PAC Reader is, in effect, the launcher’s content companion.

What Gateway does not read

The launcher consumes no cards, configs, or index rows; its only PAC data is the identity wheel plus the overlay binding. Community identity on the home screen is therefore entirely card-driven: swap the PAC, and the wheel repaints.
