== 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

== Reading group ==
* We will discuss "" on
*
* Questions to ask and goals to have:
* What aspects of the paper are questionable?
* Are there immediate actions we can take based on this work?
* Are there long-term actions we can take based on this work?
* Is there future work that we want to call out in hopes
that others will pick it up?

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?
