Findings + review doc: docs/reviews/001-implementation-review.md (the
alkcall house pattern). Closes tunnels/review-core-crates and
tunnels/review-impl.
Findings:
- U-1 [major, NOT fixed] — the local UDP adapter is not the framed
adapter ADR-003 mandates: codec-framed bytes reach real targets,
empty datagrams are EOF-shaped at the adapter (tunnel teardown),
>8 KiB datagrams split, unframed target-initiated datagrams are
dropped. Executable-pinned by real-socket probes (temporary test,
deleted after the run). Remediation task: tunnels/fix-udp-framed-adapter.
- C-1 [major, fixed] — AcceptQueue::pop lost wakeup in the
check→register window (open op hangs to the establishment bound);
fixed via the tokio notify_waiters contract (Notified created before
the check each iteration) + multi-thread regression test.
- N-4/N-5/N-7/N-8/N-9/N-10/N-11 [minor, fixed] — serialize TunnelParams
in open_reverse_channel; stale doc ref; broken doc link; root
re-exports (TunnelParams/Substrate/tunnel_open_spec/OP_TUNNEL_OPEN);
README (publish dry-run was failing on the missing readme); harness
comment; pump_against UDP framing doc note.
- N-2 retracted by executable falsification (codec buffering is
bounded by construction); N-6 non-finding with rationale.
Verified: 63 tests default / 70 with --features local, 3x repeat-run
clean both configs; clippy -D warnings (all-targets + wasm32); fmt;
doc warning-free; wasm32 check; cargo publish --dry-run passes.
