Saves the comprehensive OTA pipeline reference written by another
agent so future sessions don't lose the diagnostic flowchart or the
"three FW prerequisites" causal chain.
Tested live against current FW (v0.6.4): port 8032 reachable on both
sensors, scripts/ota-deploy.sh round-trip works, both nodes
successfully switched partitions (ota_0 ↔ ota_1) without USB+BOOT
dance. OTA is the supported path for future FW changes from this
session — sensor µs timestamp (ADR-106 open item), NVS persistence
of gain-lock (gap-analysis #5), and any larger FW work.
Kept whole (329 lines, over the usual 200 line cap for docs) because
the flowchart and pitfall table lose meaning if split. The cap is a
guideline for new project ADRs; a verbatim recipe is justified by
diagnostic value.
Catalogues, section-by-section against Pace's Part-2 article, every
ESPectre technique RuView has and does not have, plus a prioritized
roadmap (9 items, NVS persistence and FP-rate validation top of list).
Replaces the 8-item inline "open items" stub in espectre-techniques.md
with a 1-line forward link. Both files stay ≤ 200 lines per the docs
convention.
* ADR-101 raw-amplitude presence/motion classifier — per-node and
cross-node fusion logic, hysteresis, per-node UI surface
(`PerNodeFeatureInfo.classification` override).
* ADR-102 server-side NBVI subcarrier selection — formula, dead-zone
gate, ESPectre Step-1 quiet-window finder, why we split FULL vs
NBVI-subset broadband.
* ADR-103 persistent baseline + universal threshold normalization —
JSON schema v2 at `v2/data/baseline.json`, FULL-broadband over
NBVI for cross-restart stability, `norm_cv = cv / baseline_cv`
with universal 3×/6× gates, recording script workflow.
* Updated espectre-techniques.md to reflect the DONE items (Steps
1+2+4 of NBVI, baseline persistence, universal threshold) and the
remaining open items in priority order.
Each ADR ≤ 200 lines per the operator's docs convention; deep detail
lives in `docs/references/espectre-techniques.md` (also ≤ 200) which
the ADRs link to. README.md and CLAUDE.md unchanged (no extra
content added; existing >200-line state pre-dates this session).
* docs/references/espectre-techniques.md — catalogues every Pace
technique from Part-2 against what RuView has implemented, doesn't
have, or has differently. Includes ranked open-items list.
* sensing-server: revert feature_state path to vec![] amplitudes.
The previous fix made bars LOOK live by reissuing the last raw-CSI
vector on every feature_state tick — operator reported this made
the bars misleading (visually busy but unresponsive to movement).
raw.html already skips empty-amp updates so bars now refresh only
on actual fresh CSI, which is honest.
* raw.html: comment on the skip-empty branch for future-me.
