This ADR collects the immediate +fixes. + +### Fire 1 — Runaway ping zombies + +Live `ps` showed **250+ `/sbin/ping -i 0.040` processes** on the Mac, most +parented to PID 1 (orphans from prior server lifetimes) and **8 fresh +pings to `127.0.0.1` parented to the current server**. + +Root cause: a `cargo test --workspace` run sent UDP packets to +`127.0.0.1:5005` from `tests/multi_node_test.rs::test_multi_node_udp_send` +while the production server was bound to `0.0.0.0:5005`. The integration +test injects 55 synthetic frames with `node_ids = [1, 2, 3, 5, 7]`. Each +distinct `node_id` byte in a CSI magic packet triggered a fresh entry in +`NODE_ADDRS`, and the keepalive task spawned exactly one `ping` child +per entry. Combined with macOS not propagating parent death to children +(killed servers leave ping orphans), the count accumulated rapidly. + +### Fire 2 — Per-node feature divergence on node 2 + +Node 2 (192.168.0.100) showed `dominant_freq_hz: 0.05` vs node 1 (.101) +`6.30` — a 126× split in the same room. Pointed to stale gain-lock on +node 2 from a different AP/orientation. Cleared via +`POST /ota/recalibrate` (ADR-109) — sensor re-runs the 300-packet +calibration sampler at next boot. + +### Correctness issues (server auditor) + +* `run_wiflow_inference` hardcoded keypoint `confidence: 1.0` — lied about + data quality. Real signal: the runtime classifier's `confidence`. +* `wiflow_v1.rs` zero-pad path duplicated subcarrier index 0 instead of + zero-padding when < 35 finite subcarriers — comment said "zero the + rest", code did the opposite. +* `nbvi_history.clone()` cloned the entire 600-deep VecDeque (≈270 KB) on + every inference, while only the last 20 frames are used. +* `run_wiflow_inference` picked the node with longest history regardless + of recency — stale data from a dead sensor would keep producing pose. + +### UI issues (UI auditor) + +* `/` served a static API-index HTML page; users typing `localhost:8080` + never reached the SPA at `/ui/index.html`. +* `
` was empty; `app.js::SensingTab.mount` queried + `#sensing-container` and rendered into nothing — the Sensing tab was + permanently blank. +* `LiveDemoTab.fetchModels` unconditionally overwrote `activeModelId = + 'wiflow-v1'` whenever `/api/v1/info` reported `pose_estimation: true`, + even when the operator had just loaded an RVF model. Dropdown silently + flipped back to WiFlow on every refresh. + +### Docs issues (docs auditor) + +* `CHECKLIST.md` header: `head c827cde6`, count `43 Done` — stale + by 4 commits and 2 ADRs. +* `ADR-115 References` cited "ADR-100 — TP-Link WISP" (it's ADR-110) + and "ADR-108 / ADR-111" (ADR-111 doesn't exist — folded into ADR-109). +* `espectre-gap-analysis.md::Still open` table listed 8 items as open + that had already shipped (ADR-104, ADR-109, ADR-112, ADR-114). +* `ota-pipeline.md` documented OTA flashing but never mentioned + `/ota/set-target` (ADR-115) or `/ota/recalibrate` (ADR-109) — operator + hitting the "Mac moved networks" scenario wouldn't find the recovery + path. + +## Decisions + +### D1 — UDP receiver filters loopback before NODE_ADDRS + +`main.rs::udp_receiver_task` now rejects loopback, unspecified, multicast, +and broadcast source addresses before inserting into `NODE_ADDRS`. Packets +still parse and feed the classifier — only the keepalive registration +is gated. Defends against any local sender (tests, simulators, future +tooling) accidentally driving ping spawn. + +### D2 — Keepalive pre-reap at startup + +`main.rs::csi_keepalive_task` runs `pkill -f "/sbin/ping -i 0.040"` and +`pkill -f "/usr/bin/ping -i 0.040"` once at task entry. Cleans up +orphans from prior server lifetimes without operator action. Cost: two +`pkill` invocations at startup, ~10 ms total. Idempotent. + +### D3 — Real keypoint confidence + +`run_wiflow_inference` now stamps `confidence = amp_classify_from_latest` +runtime classifier confidence onto all 17 keypoints (was `1.0` hardcoded). +The lite-scale wiflow has no per-keypoint uncertainty head; this signal +is the most honest stand-in. Currently reading **0.037** on the live +deployment — accurate reflection of "wiflow output is saturated, don't +trust these coords". + +### D4 — Zero-pad fix in wiflow_v1 + +`build_input_from_history` now pushes `None` into `picks` for dead slots +and writes `0.0f32` into those rows. Prior code pushed `0usize` → all +unused channels read subcarrier-0 amplitudes, feeding the network 35× +the same signal. + +### D5 — Tail-clone optimisation + +`run_wiflow_inference` snapshots only the last 20 entries from +`nbvi_history` while holding the lock, not the full 600-deep deque. Lock +hold time dropped from ~µs * 600 to ~µs * 20 per tick. + +### D6 — `/` → `/ui/index.html` permanent redirect + +`main.rs::root_redirect` returns HTTP 308. API-index HTML moves to `/api` +for operators / curl debugging. Users typing the bare host land on the +SPA. + +### D7 — Sensing tab container restored + +`ui/index.html`: `
` now contains `
` matching `app.js::SensingTab.mount`'s query +selector. + +### D8 — LiveDemoTab WiFlow inject only when no model active + +`LiveDemoTab.fetchModels` wraps the `activeModelId = 'wiflow-v1'` +assignment in `if (!this.modelState.activeModelId)`. RVF model loads +keep their displayed name. + +### D9 — Multi-node test guards against external :5005 owner + +`tests/multi_node_test.rs::test_multi_node_udp_send` probes +`127.0.0.1:5005` with a transient bind; if the bind fails, the test +skips its UDP send rather than polluting whoever owns the port. Belt- +and-braces with the server-side filter (D1). + +### D10 — Docs sweep + +* `CHECKLIST.md`: header to `head 0ec1e4b0`, count to **47 Done**, + explicit note that ADR-111 is intentionally absent.
