name: federation-peer-rust

# Builds + tests the v3/crates/ruflo-federation-peer crate (ADR-120
# Step 3). Triggers only on changes to the crate or this workflow.
# Two jobs:
#
#   stable-noop  — cargo build + cargo test without --features native.
#                  Verifies the trait surface compiles in a tree that
#                  doesn't have the upstream crate deps materialized.
#
#   stable-native — cargo check --features native. Pulls in
#                   midstreamer-quic@0.2.1 + aimds-*@0.1.1 from
#                   crates.io. Type-checks only (the placeholder impls
#                   don't yet exercise the upstream APIs).
