- CI (release.yml/build.yml): remove fetch-nym + AWS_LC_SYS_PREBUILT_NASM; the default cargo build --release is Tor/arti only now (nip44 fetch kept). - Cargo.toml: nym-sdk is optional behind the `nym` feature so the default build never pulls it. - Delete the dead Nym-era probes (xrelay_smoke, connect_timing, tunnel_measure) that referenced the removed Nym API and broke `cargo test`. - Untrack the internal E2E harnesses (e2e.rs, nostr_e2e.rs) via .gitignore; gate `mod e2e` behind the `e2e-internal` feature so clones still compile. - Refresh stale Nym comments in build.rs and the build scripts.
