From 46ae11531c95cc658710b18109880bc047eac9ee Mon Sep 17 00:00:00 2001 From: ruvnet Date: Sun, 3 May 2026 16:51:17 -0400 Subject: [PATCH] test(hailo): Pi-gated integration test locks in iter-163 throughput (iter 172) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Iter-165 leftover #4 closed. New crates/ruvector-hailo-cluster/tests/pi_hardware_integration.rs runs three end-to-end tests against a real Pi worker, gated on RUVECTOR_TEST_PI_HOST being set. Without the env var all three tests skip cleanly so default cargo test is unaffected. Tests: pi_worker_returns_real_semantic_vectors Embeds the same three reference phrases the iter-167 worker self-test uses; asserts sim(dog,puppy) > sim(dog,kafka) with a margin > 0.10. Catches encoder degeneration that iter-167's in-process check would miss (e.g. corrupt model in a deploy push that bypassed install.sh). pi_worker_throughput_above_floor Sequentially embeds 30 sentences, asserts >= 5 embeds/sec. Floor lets a Pi 4 (~3-4/sec estimated) fail loudly while Pi 5 cpu-fallback (7/sec) and NPU (67/sec) pass. pi_worker_handles_padding_and_truncation Empty string + 200-repeat long string both produce finite 384-dim vectors. Shape contract regression gate. Run live against cognitum-v0 (Pi 5 + AI HAT+ NPU worker on 50051): Pi cognitum-v0:50051: sim(dog,puppy)=0.5019 sim(dog,kafka)=0.2692 Δ=+0.2327 Pi cognitum-v0:50051: 30 embeds in 1.36s = 22.0 embeds/sec test result: ok. 3 passed; 0 failed; 0 ignored The 22/sec is single-threaded sequential (no client concurrency); matches the iter-163 single-thread profile. Concurrent dispatch hits the iter-163 67.3/sec ceiling. Default cargo test on x86 dev box: 3 tests skip cleanly with the "set RUVECTOR_TEST_PI_HOST" message — CI safe. Iter 172 closes the agreed "Clean Exit" sprint. Remaining items (mask-aware HEF, sysroot cross-build, real calibration corpus, multi-network HEF) are research / strategic decisions left as future work.
