From 2f331ad3a4e8fb270dec06aa58d5cbbef85df4a2 Mon Sep 17 00:00:00 2001 From: ruvnet Date: Sat, 2 May 2026 14:45:48 -0400 Subject: [PATCH] feat(mmwave-bridge): cluster sink via embed RPC + ADR status updates (iter 116-117) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Iter 116 — wire `ruvector-mmwave-bridge` into the cluster's embed RPC: --workers cluster sink (same semantics as embed/bench) --dim expected vector dim (default 384) --fingerprint worker-fingerprint enforcement --allow-empty-fingerprint bypass the §2a empty-fp gate Each decoded radar event is converted into a short natural-language description ("heart rate 72 bpm at radar sensor", "person detected at radar sensor", etc.) and posted to the cluster via the existing embed RPC. The cluster's full security stack — §1b mTLS, §2a fp+cache gate, §3b rate-limit interceptor — applies to this traffic with no additional code in the bridge. Plaintext gRPC for now (Tailscale encrypts the wire); the existing `tls` feature on the cluster crate applies to the bridge by inheritance once the operator turns it on. Verified end-to-end live: $ ruvector-hailo-fakeworker (background, port 58213, dim=4, fp:demo) $ ruvector-mmwave-bridge --simulator --rate 5 \ --workers 127.0.0.1:58213 --dim 4 --fingerprint fp:demo ruvector-mmwave-bridge: cluster sink active — 1 worker(s), dim=4, fp="fp:demo" ruvector-mmwave-bridge: simulator mode @ 5 Hz (no hardware required) ruvector-mmwave-bridge: posted text="breathing rate 12 bpm at radar sensor" dim=4 ok ruvector-mmwave-bridge: posted text="heart rate 67 bpm at radar sensor" dim=4 ok ruvector-mmwave-bridge: posted text="nearest target distance 106 cm at radar sensor" dim=4 ok ruvector-mmwave-bridge: posted text="person detected at radar sensor" dim=4 ok … 10 successful embed RPCs in 2 seconds — full pipeline (radar event → NL description → gRPC → fakeworker → vector returned) works. Failures don't kill the bridge: cluster post errors get logged but JSONL events keep flowing on stdout, so a downstream consumer that doesn't depend on the cluster (jq pipeline, log scraper) keeps working even when the cluster is down. Iter 117 — ADR documentation pass: ADR-167 (Hailo NPU embedding backend): comprehensive iter-99-116 status table — what shipped, what's HEF-blocked, what's deferred. Original iter-15 validation snapshot preserved as historical context. ADR-168 (cluster CLI surface): adds `ruvector-mmwave-bridge` as the sixth bin (sensor: 60 GHz mmWave radar UART → cluster embed RPC). ADR-172 (security review): "Implemented (modulo cross-ADR + HEF-blocked items)" — 2/4 HIGH ✓, 6/8 MEDIUM ✓, all 4 unshipped items are legitimately blocked/out-of-scope (cross-ADR §7a/§7b or HEF-gated §6a or doc-only §1d). Iter table 99→111 captures each landing commit. ADR-174 (thermal): partially implemented — CLI + service + install + 6 tests shipped iter 91-98. Per-workload Unix-socket subscriber deferred until the HEF compile lands and there's a real thermal load to manage. Validation: 132 host tests + composition test green. Clippy --all-targets -D warnings clean for default and tls feature configs.
