Rollback-enabled nodes (CONFIG_BOOTLOADER_APP_ROLLBACK_ENABLE=y) boot an
OTA'd image as PENDING_VERIFY, but nothing called
esp_ota_mark_app_valid_cancel_rollback(), so every OTA reverted at the next
reset, a second OTA was refused until then, and a bad image was never
deliberately rolled back.
- main/ota_health.{c,h}: at boot, if the running image is PENDING_VERIFY,
poll for STA got-IP and >=1 CSI frame accepted by the stream sender.
Confirm after CONFIG_OTA_HEALTH_MIN_UPTIME_S (30 s) once both are in;
roll back via esp_ota_mark_app_invalid_rollback_and_reboot() if they are
not in by CONFIG_OTA_HEALTH_TIMEOUT_S (120 s from boot). VALID, UNDEFINED,
NEW and no-otadata/factory images are left alone. The decision is a pure
header function, host-tested in test/test_ota_health.c (make host_tests).
- CONFIG_OTA_HEALTH_FORCE_FAIL (test only) rolls back where it would have
confirmed, for proving rollback on hardware.
- GET /ota/status reports ota_state so durability is visible remotely.
- RUNBOOK: replace the nonexistent ota_rollback_boot_check() claim and
document the behaviour and the hardware check (2.1).
Hardware-verified on an ESP32-S3 (push, confirm, hard reset, forced
rollback) and an ESP32-C6 (push, confirm, hard reset); see ADR-379, next in
this series. Host tests: make host_tests passes, including run_ota_health.

Follow-up to the review on #1797. The CRITICAL -> THROTTLED edge was
unconditional: any reading below critical_c dropped the state immediately, so a
node sitting on the critical boundary flapped between TXP_MIN and TXP_STEP2
indefinitely. Every oscillation moves that node's RSSI at both ends, which a
reader cannot distinguish from an obstruction -- exactly the failure the
hysteresis on the other edges was added to prevent.
Now every falling edge requires cooling a full hysteresis band below the
threshold it crossed on the way up; rising edges stay immediate, because heat is
a reason to act now. Verified by dithering across the boundary: six readings
either side of 80 C previously produced five state changes, now zero.
The decision moved into thermal.h as a pure function, following the convention
edge_processing.h already uses for edge_evidence_person_count -- a host test
then exercises the exact function the device build runs rather than a copy free
to drift.
BEHAVIOUR CHANGE worth calling out, beyond what the review asked for. The old
`recover` point was a single global threshold (throttle_c - hyst) that every
state fell back through, so leaving WARN required cooling to 64 C -- a bound
derived from the throttle threshold, not WARN's own. Hysteresis is now relative
to each state's own entry point, so WARN releases at 57 C instead. Leaving
THROTTLED is unchanged at 64 C. Kconfig help updated, since it described the old
throttle-relative semantics.
One consequence the test pins explicitly: with the default constants the
critical exit point (80 - 8 = 72) coincides exactly with the throttle threshold,
so a node cool enough to leave CRITICAL is already below THROTTLED's entry and
lands in WARN. THROTTLED is unreachable descending from CRITICAL at hysteresis
8. That falls out of the chosen constants rather than the logic, and the test
covers hysteresis 4 as well to show the intermediate step reappears when the
bands do not coincide. My first version of the test asserted THROTTLED there and
was simply wrong -- running it caught that.
Verified in espressif/idf:v5.4: against the unfixed transition the test fails
five checks including the dither, passes with the fix, and the C6 firmware
builds. Still no hardware evidence for this PR -- a real boot log is coming
before merge, as promised earlier in the thread.

Bug #2 (root cause): LD2410 probe-detection matched only the 4-byte head
0xF4F3F2F1, so a floating UART at 256000 baud could phantom-detect a sensor
and spawn a UART task. Now requires a full validated report frame (head +
sane length + tail 0xF8F7F6F5), extracted to mmwave_detect.h and shared with
a host unit test (test_mmwave_detect.c, 8 vectors) so firmware and test can't
diverge. Matches the validate-before-trust approach used for MR60 in #1107.
Bug #1: sendto ENOMEM used a fixed 100 ms backoff too short to drain sustained
lwIP/WiFi buffer pressure, so a node could stay stuck. Now exponential
(100->200->...->2000 ms per consecutive ENOMEM, reset on first successful
send). Removing the phantom LD2410 task (bug #2) also removes the extra load
that tipped the reporter's tier-2 node into the stuck state.
Validated on ESP32-S3 QFN56 rev v0.2 (the reporter's silicon): tier-2 streams
~100 frames/s with no stuck ENOMEM and correctly reports no mmWave (no
phantom). LD2410 predicate truth table proven (head-without-tail REJECTED).
Could not reproduce the reporter's environment-specific floating-pin noise, so
the deterministic proof is the host unit test.
* fix(firmware): gate phantom persons + add presence hysteresis (#998, #996)
Two ESP32 edge-vitals logic bugs in edge_processing.c. Both are
robustness/logic fixes — NOT validated-accuracy claims. True count/PCK
vs labelled ground truth remains hardware/data-gated (COM9 ESP32-S3).
#998 — n_persons over-counted (reported 4 for one person):
update_multi_person_vitals() split top-K subcarriers into top_k_count/2
groups and marked EVERY group active, so one body's multipath always
read the full EDGE_MAX_PERSONS. Added two pure, host-testable helpers:
- count_distinct_persons(): per-group energy gate
(EDGE_PERSON_MIN_ENERGY_RATIO) + spatial dedup
(EDGE_PERSON_MIN_SC_SEP) so weak/adjacent multipath groups don't
count as separate bodies. Strongest group always counts (>=1).
- person_count_debounce(): a gated count must hold
EDGE_PERSON_PERSIST_FRAMES consecutive frames before it's emitted,
so a single noisy frame can't promote a phantom.
The active flags now mark only the strongest stable_count groups.
#996 — presence flag flickered at ~50cm despite high presence_score:
the bare `score > threshold` compare chattered on a noisy score
(field-observed 2.6-26.7 frame-to-frame). Replaced with a Schmitt
trigger + clear-debounce (presence_flag_update): assert above
threshold, hold in the dead band down to threshold *
EDGE_PRESENCE_HYST_RATIO, clear only after EDGE_PRESENCE_CLEAR_FRAMES
consecutive sub-low frames. presence_score itself is unchanged and
still emitted for consumer-side thresholding.
All thresholds are named, documented constants in edge_processing.h.
Firmware builds clean for esp32s3 (idf.py build RC=0).

* test(firmware): host C99 tests for vitals count + presence logic (#998, #996)
test/test_vitals_count_presence.c pins the two fixes with deterministic
host-buildable tests (no ESP-IDF needed). 13 cases / 22 assertions, all
passing under gcc 13 -Wall -Wextra:
#998 count gate: single strong signature + multipath -> count==1;
two well-separated -> 2; two strong-but-adjacent -> 1 (dedup);
no signal -> 0; three well-separated -> 3.
#998 debounce: transient spike rejected; sustained change accepted;
flapping count stays stable.
#996 presence: dithering trace -> stable flag (no flicker); brief dips
held by clear-debounce; genuine departure clears within hold window;
dead-band holds state.
The named tuning constants are #include'd from the real
edge_processing.h so the test and firmware can never disagree on
thresholds. `make run_vitals` / `make host_tests` added; binaries
gitignored.
Hardware-gated caveat documented in the test header: these pin the
decision LOGIC; the exact energy/separation/hysteresis values that best
match a real room vs labelled occupancy remain on-device tuning.

* fix(sensing-server): emit real field-derived person position/motion to /ws/sensing (#1050)
The Observatory 3D figure never animated because the sensing_update WS
frame carried no per-person position/motion_score/pose — only image-space
keypoints. The FigurePool/PoseSystem (and demo-data.js's own contract)
animate each figure from persons[i].position (room-world), .motion_score
(0..100), and .pose; none were on the live stream.
Honest scope (Case 2): the pipeline has no calibrated per-person room
localizer or per-person skeletal pose. New field_localize module extracts
the strongest peak(s) from the real signal_field grid (subcarrier
variances x motion-band power) and maps the peak cell to Observatory world
coords with the exact _buildSignalField transform. motion_score is the
measured motion_band_power passed through; pose is set only from a real
aggregate posture estimate, else None (never a fabricated skeleton).
Empty/below-threshold field -> persons: [] (no phantom); present person
with no resolvable peak keeps position [0,0,0], not invented coords.
attach_field_positions runs after the tracker step at all five broadcast
sites. New position/motion_score/pose fields added to both PersonDetection
structs. No UI change needed — the Observatory already reads these fields.
Tests: field_localize peak/coordinate/empty/separation units +
observatory_persons_field_position_tests (known-peak -> emitted position,
empty-room -> no phantom, pose real-or-None, below-threshold honesty).
sensing-server bin 441->451, 0 failed.

* ci: fix Fuzz Testing + Swarm Test (ADR-062) workflow regressions
Both have been red on main for ~5 weeks; root-causing them so PR #590
can land green rather than merging on top of pre-existing breakage.
- esp_stubs.h: add wifi_ps_type_t enum (WIFI_PS_NONE/MIN/MAX) and
esp_wifi_set_ps() stub. csi_collector.c:346 added a real
esp_wifi_set_ps(WIFI_PS_NONE) call to disable modem sleep
(RuView#521 fix); the host-native fuzz target couldn't link.
- scripts/qemu_swarm.py: pass --force-partial to provision.py.
The per-node TDM/channel overlay intentionally omits WiFi
credentials (those live in the base flash image), but the
issue #391 wifi-trio guard now rejects calls missing the
--ssid/--password trio. --force-partial is exactly the opt-in
for this case.

* fix(firmware): fall detection false positives + 4MB flash support (#263, #265)
Issue #263: Default fall_thresh raised from 2.0 to 15.0 rad/s² — normal
walking produces accelerations of 2.5-5.0 which triggered constant false
"Fall Detected" alerts. Added consecutive-frame requirement (3 frames)
and 5-second cooldown debounce to prevent alert storms.
Issue #265: Added partitions_4mb.csv and sdkconfig.defaults.4mb for
ESP32-S3 boards with 4MB flash (e.g. SuperMini). OTA slots are 1.856MB
each, fitting the ~978KB firmware binary with room to spare.

* fix(ci): repair all 3 QEMU workflow job failures
1. Fuzz Tests: add esp_timer_create_args_t, esp_timer_create(),
esp_timer_start_periodic(), esp_timer_delete() stubs to
esp_stubs.h — csi_collector.c uses these for channel hop timer.
2. QEMU Build: add libgcrypt20-dev to apt dependencies —
Espressif QEMU's esp32_flash_enc.c includes <gcrypt.h>.
Bump cache key v4→v5 to force rebuild with new dep.
3. NVS Matrix: switch to subprocess-first invocation of
nvs_partition_gen to avoid 'str' has no attribute 'size' error
from esp_idf_nvs_partition_gen API change. Falls back to
direct import with both int and hex size args.

* fix(ci): pip3 in IDF container + fix swarm QEMU artifact path
QEMU Test jobs: espressif/idf:v5.4 container has pip3, not pip.
Swarm Test: use /opt/qemu-esp32 (fixed path) instead of
${{ github.workspace }}/qemu-build which resolves incorrectly
inside Docker containers.

* fix(ci): source IDF export.sh before pip install in container
espressif/idf:v5.4 container doesn't have pip/pip3 on PATH — it

QEMU rejects flash images that aren't exactly 2/4/8/16 MB.

* fix(ci): source IDF export before NVS matrix generation in QEMU tests

* fix(ci): QEMU validation treats WARNs as OK + swarm IDF export
1. validate_qemu_output.py: WARNs exit 0 by default (no real WiFi
hardware in QEMU = no CSI data = expected WARNs for frame/vitals
checks). Add --strict flag to fail on warnings when needed.
2. Swarm Test: source IDF export.sh before running qemu_swarm.py
so pip-installed pyyaml is on the Python path.

* fix(ci): provision.py subprocess-first NVS gen + swarm IDF venv
provision.py had same 'str' has no attribute 'size' bug as the
NVS matrix generator — switch to subprocess-first approach.
Swarm test also needs IDF export for the swarm smoke test step.

* fix(ci): handle missing 'ip' command in QEMU swarm orchestrator
The IDF container doesn't have iproute2 installed, so 'ip' binary

FileNotFoundError in _run_ip() for robustness.

* fix(ci): skip Rust aggregator when cargo not available in swarm test
The IDF container doesn't have Rust installed. Check for cargo
with shutil.which() before attempting to spawn the aggregator,
falling back to aggregator-less mode (QEMU nodes still boot and
exercise the firmware pipeline).

* fix(ci): treat swarm test WARNs as acceptable in CI
The max_boot_time_s assertion WARNs because QEMU doesn't produce

without real hardware; only exit code 2+ (FAIL/FATAL) should fail.

* fix(firmware): Kconfig EDGE_FALL_THRESH default 2000→15000
The nvs_config.c fallback (15.0f) was never reached because
Kconfig always defines CONFIG_EDGE_FALL_THRESH. The Kconfig
default was still 2000 (=2.0 rad/s²), causing false fall alerts
on real WiFi CSI data (7 alerts in 45s).
Fixed to 15000 (=15.0 rad/s²). Verified on real ESP32-S3 hardware
with live WiFi CSI: 0 false fall alerts in 60s / 1300+ frames.
