Guphub room roles

Make room roles control who speaks and who listens.

Interactive study

From the example below.

Why I’m interested

An audio room has a social structure before it has an audio connection. Hosts run the room, invited speakers talk, and listeners choose to listen. Guphub ties those roles to the permissions that control the microphone, so the product's rules and the audio system agree.

Progress

My local work includes a Rust control plane, native iOS and Android clients, LiveKit integration, and developer handoff. The browser example evaluates a room policy across hosts, speakers, listeners, and a closed room. The next integration compares those decisions with the actual grant contract.

The role decides who gets the microphone

Choose a role, then compare its publication permission with a closed room.

Choose an example

HostInvited speakerListenerRoom closed

One room, explicit audio roles

An open room permits its host and accepted speakers to publish audio. Listeners receive audio. Close the room and every role loses publication access.

Room: Open
Role: Host
Audio publication: Permitted

Result

can_publish_audio = true
room_open = true
invitation_accepted = true

One room, explicit audio roles

An open room permits its host and accepted speakers to publish audio. Listeners receive audio. Close the room and every role loses publication access.

Room: Open
Role: Invited speaker
Audio publication: Permitted

Result

can_publish_audio = true
room_open = true
invitation_accepted = true

One room, explicit audio roles

An open room permits its host and accepted speakers to publish audio. Listeners receive audio. Close the room and every role loses publication access.

Room: Open
Role: Listener
Audio publication: Denied

Result

can_publish_audio = false
room_open = true
invitation_accepted = false

Rust evaluates this policy for an imaginary room. The next integration matches these decisions to the Guphub control plane's LiveKit grants.

What comes next

Match the example decisions to the LiveKit grant contract and exercise the authentication path.

Implementation and credits

How do the room state and role control audio publication?

A Rust rule evaluates audio publication for an imaginary room and its roles.

Choose a role or close the room and inspect the audio publication decision.

Rust evaluates the browser policy example. LiveKit and native clients handle the audio product.

Collaborative Guphub work builds on an imported MVP. My local implementation covers the Rust backend, native clients, and developer handoff.
