== Discussion ==

     * Snowflake broker transition still pending.

     * Adding a snowflake transport to lyrebird
         * 
https://gitlab.torproject.org/tpo/anti-censorship/pluggable-transports/lyrebird/-/merge_requests/63
         * Squash PTs into Lyrebird: 
https://gitlab.torproject.org/tpo/anti-censorship/pluggable-transports/lyrebird/-/issues/40015
         * TODOs: add proxy support and event logging
         * We decide is a good idea to integrate the snowflake client 
into lyrebird
         * we are not removing the snowflake client from the snowflake 
proyect for now, we'll keep both until it becomes a burden.
         * only the snowflake client will be integrated in lyrebird, not 
the server

     * pion/webrtc v4 release is out
         * it has support to integrate with covert-dtls
         * on the beta testing there were some issues, we'll need to 
check if it works with the release or it needs work

     * split broker into components
         * there is an old MR with a WIP version of this change
         * we are still interested on it
         * cohosh will check with arlo if he can continue that work or 
we'll close it for now

             * Are there long-term actions we can take based on this work?

onyinyang: 2024-10-31
     Last week(s):
         - MR for troll-patrol integration for Lox bridge blockage detection
             - 
https://gitlab.torproject.org/tpo/anti-censorship/lox/-/merge_requests/263
             - improved on the graceful exit and blockage detection 
elements from last week
             - work is ongoing from vecna so will update this further 
when that's in a more complete state
         - discussed plans for dropping lox-wasm with browser team
         - test distributor implementation
     Next week:
         - Finish up test distributor implementation and deploy test 
distributor
         - update lox protocols to return duplicate responses for an 
already seen request
         - add issuer improvements to lox protocols
         - Work on outstanding milestone issues:
             in particular: 
https://gitlab.torproject.org/tpo/anti-censorship/lox/-/issues/69
             - key rotation automation

         Later:
         pending decision on abandoning lox wasm in favour of some kind 
of FFI? 
https://gitlab.torproject.org/tpo/applications/tor-browser/-/issues/43096):
             - add pref to handle timing for pubkey checks in Tor browser
             - add trusted invitation logic to tor browser integration:
https://gitlab.torproject.org/tpo/applications/tor-browser/-/issues/42974
         - improve metrics collection/think about how to show Lox is 
working/valuable
         - sketch out Lox blog post/usage notes for forum

     (long term things were discussed at the meeting!):
         - brainstorming grouping strategies for Lox buckets (of 
bridges) and gathering context on how types of bridges are 
distributed/use in practice
             Question: What makes a bridge usable for a given user, and 
how can we encode that to best ensure we're getting the most appropriate 
resources to people?
                 1. Are there some obvious grouping strategies that we 
can already consider?
                     e.g., by PT, by bandwidth (lower bandwidth bridges 
sacrificed to open-invitation buckets?), by locale (to be matched with a 
requesting user's geoip or something?)
                 2. Does it make sense to group 3 bridges/bucket, so 
trusted users have access to 3 bridges (and untrusted users have access 
to 1)? More? Less?
