All passed with no failures.\n\n## Nine-Requirement Pass/Fail Checklist\n\n1. Define a Rust transport PoC with distinct forward and return-path interfaces, stream/session IDs, packet sequence numbers, bounded send/receive windows, retransmission state, and deterministic configuration.  \n   **Status: PASS**  \n   Evidence: src/lib.rs, src/simulation.rs, src/wire.rs implement session-tagged frames, bounded windows (window=64), sequence numbers, deterministic seeds. See `cargo test` output (15/15 passed) and `cargo run` output showing deterministic scenarios.\n\n2. Implement a unidirectional-aware ACK scheme using cumulative/range acknowledgments grouped into epochs, with ACK-rate caps and explicit handling for loss, duplication, delay, and reordering on the return path.  \n   **Status: PASS**  \n   Evidence: src/ack.rs (ack_state_merges_reordering_and_ignores_duplicates, ack_state_enforces_rate_and_memory_bounds tests pass), src/wire.rs (data_and_ack_frames_round_trip test). `cargo test` confirms.\n\n3. Implement sender congestion and loss control that does not treat delayed return-path ACKs as immediate forward-path congestion: ACK-delay accounting, packet/time loss thresholds, bounded recovery, retransmission scheduling, and fairness/backpressure limits.  \n   **Status: PASS**  \n   Evidence: reverse_path_bottleneck scenario in `cargo run` output: asymmetric shows rtx=453 vs naive rtx=805 and timeouts=805; min_cwnd=2 vs naive min_cwnd=1. simulation::tests pass.\n\n4. Implement deterministic seeded RDV jitter queues with configurable delay distributions and safety bounds, so timing masking is reproducible and does not create unbounded latency or memory growth.  \n   **Status: PASS**  \n   Evidence: src/jitter.rs (jitter::tests pass: delays_are_seeded_and_bounded, queue_refuses_growth_past_packet_bound, queue_releases_in_time_then_key_order). high_seeded_jitter scenario in `cargo run`: max_jitter_queue=32 bounded. timing_linkability shaped=0.594.\n\n5. Integrate the transport, ACK, congestion/loss, and jitter components into a single deterministic simulation harness that runs the complete scenario matrix.  \n   **Status: PASS**  \n   Evidence: src/simulation.rs (simulation::tests::asymmetric_sender_completes_the_required_matrix, baseline_is_deterministic pass). `cargo run` executes full matrix (9 scenarios + udp_loopback).\n\n6. Provide an end-to-end localhost UDP demonstration using four distinct sockets (forward data path + separate return ACK path) that completes 16 sequences within configured time.  \n   **Status: PASS**  \n   Evidence: udp_loopback in `cargo run` output: completed=true sent=16 received=16 ack_datagrams=3 max_receiver_packets=16.\n\n7. Demonstrate that the asymmetric transport avoids the ACK collapse and RTT leak exhibited by the naive baseline under asymmetric paths, high jitter, loss, and reordering.  \n   **Status: PASS**  \n   Evidence: All asymmetric scenarios in `cargo run` complete faster with fewer rtx/timeouts than naive (e.g., reverse_path_bottleneck: asymmetric 52410ms vs naive 122870ms). timing scores and 15 tests pass.\n\n8. Include `cargo fmt --check`, `cargo clippy --all-targets -- -D warnings`, `cargo test`, and documented example/benchmark commands that all pass cleanly.  \n   **Status: PASS**  \n   Evidence: \n   - `cargo fmt --check`: (no output, exit 0)\n   - `cargo clippy --all-targets -- -D warnings`: Finished dev profile, no warnings\n   - `cargo test`: 15 tests passed\n   - `cargo run`: full output captured above showing all scenarios and udp_loopback + timing scores.\n\n9. Ensure the PoC produces reproducible timing-linkability evidence (raw vs shaped scores) without claiming production privacy properties.  \n   **Status: PASS**  \n   Evidence: `cargo run` final line: timing_linkability: raw=1.000 shaped=0.594 metric=absolute_gap_correlation. README.md documents the metric and that it is evidence for the harness, not a privacy claim.
