Verify hang up at Phase 3

./verify - hang up at Phase 3:

[PHASE 3] Rust workspace tests (cargo test --workspace --no-default-features)

Hardware: RK3588
OS: Ubuntu 20.06 64bit arm64
Python: 3.8

[ruvnet]

Thanks for the report. To reproduce and diagnose this we need a bit more detail:

1. Full terminal output: please paste the complete output from cargo test --workspace --no-default-features up to the point it hangs (or the last line printed before it stalls).
2. Hang behaviour: does the process sit silently with 100% CPU, block on I/O, or just produce no output for a long time? Roughly how long did you wait before killing it?
3. Which crate stalls: does cargo test -p <specific-crate> --no-default-features also hang, or does a per-crate run complete? Running one crate at a time can narrow the scope quickly.
4. Rust/cargo version: output of rustc --version && cargo --version.
5. Available memory: free -h — some crates require significant RAM to link on arm64 and an OOM-kill can look like a silent hang.

RK3588 / arm64 is not a standard CI target, so any reproducer details you can share are especially helpful.

Thanks for reporting. To make this actionable, a few more details would help:

1. Full error output — the complete cargo test --workspace --no-default-features output from the point it hangs or fails, not just the phase header.
2. Rust toolchain — output of rustc --version and cargo --version.
3. Does it hang or error? — If it hangs, does cargo test --workspace --no-default-features -- --test-threads=1 reproduce it? If it errors, paste the full stderr.
4. Workspace state — any prior cargo build artifacts, or a fresh clone? RK3588 has 8 cores; a parallel-test deadlock would show differently than a build failure.

The arm64 Linux path is exercised in CI but the RK3588 SoC is outside the tested matrix, so a full trace is needed to distinguish a toolchain/platform issue from a genuine test failure.

Could you share the terminal output just before the hang, and confirm whether it stops mid-test or before any test runs?

On aarch64 (RK3588), the most common culprits for cargo test --workspace hanging at Phase 3 are:

1. A test that spawns a Tokio runtime or blocks on a network socket indefinitely
2. A BLAS/LAPACK link that stalls on a missing symbol rather than failing cleanly
3. A test binary that forks and waits for a child process that never exits

The fastest way to isolate it:

cargo test --workspace --no-default-features -- --test-threads=1 2>&1 | head -200

Single-threading forces each test to run and report sequentially, so the last printed test name before the hang identifies the blocking test. If that also hangs silently, try:

cargo test --workspace --no-default-features --no-run 2>&1
# Then run each binary individually:
./target/debug/deps/<binary_name> --test-threads=1

If the hang is reproducible, strace -f -e trace=futex,clone,wait4 on the stuck process will show whether it is blocked on a mutex, a child wait, or a syscall.
