0fc168d875 Improved LBT behaviour - CAD-to-RX, correct symbol times, better thresholds (#11137)
* LoRa LBT: fix SX128x/SX126x CAD encoding + slot model, ESP32 sleep race

Three fixes from the "are we really listening?" LBT audit:

- SX128x CAD: pass RADIOLIB_SX128X_CAD_ON_4_SYMB instead of the raw count 4.
  The raw value set bits 7:5 = 000, i.e. a 1-symbol scan, leaving LBT nearly
  blind on 2.4 GHz. Now runs the intended 4-symbol CAD.

- SX126x CAD / slot time: name the symNum value explicitly as CAD_ON_4_SYMB
  (identical 0x02 raw value, so no on-air change) and add a virtual
  getCadSymbolCount() so computeSlotTimeMsec() models the real ~4.5-symbol
  scan for the SX126x/LLCC68/STM32WL family only, leaving LR11x0/SX127x at
  their correct 2.5 symbols. Fixes the too-short contention-window slots.

- ESP32 light sleep: if the DIO1/RF95_IRQ line is already asserted just before
  esp_light_sleep_start(), skip the sleep so the main loop services the pending
  packet instead of stranding it for up to a full sleep chunk (the
  detachInterrupt-clears-the-GPIO-wake disarm race).

* LoRa LBT: keep software-poll preamble flags latched while idle (anti-stomp)

Finding #10 from the "are we really listening?" audit, LORA_DIO1_SOFTWARE_POLL
boards (meshnology-w10).

The 1 ms poll cleared latched PREAMBLE_DETECTED|HEADER_VALID whenever they were
the only bits set, so for the rest of a reception isActivelyReceiving() read idle.
A TX queued during the payload phase then passed the send gate and startTransmit
overwrote the shared chip buffer, losing the inbound packet.

That clear only exists to stop a noise preamble from permanently blocking our own
TX (starvation). Starvation can only happen when we actually have something to
send, so gate the clear on a non-empty txQueue. While the queue is empty the bits
stay latched, isActivelyReceiving() reports the in-progress packet, and a later TX
defers instead of stomping it. A queued TX still gets the escape hatch. The poll
cadence is a fixed 1 ms reschedule either way, so latched bits don't spin the loop;
readData() clears everything once a real RX_DONE arrives.

* LoRa LBT: optional RSSI energy second-gate before TX (default off)

Findings #4/#5 of the "are we really listening?" audit.

CAD only detects a preamble. A neighbour's packet whose preamble already aired -
during our own TX, a CAD scan, or a standby gap - is mid-payload and invisible to
CAD, so we key up on top of it. Add an RSSI energy check as a second listen-before-
talk gate in the TX-decision path: channelBusyByRSSI() compares the instantaneous
in-RX RSSI against the rolling noise floor (getNoiseFloor() + margin) and defers if
the channel is hot. It reads RSSI before isChannelActive()'s setStandby() via the
|| short-circuit, so the sample is taken while still in RX where GET_RSSI_INST is
valid - no mode juggling.

Orthogonal to CAD: CAD has processing gain and catches weak preambles below the
noise floor; RSSI catches strong energy at any packet phase, including the mid-
payload case CAD is blind to. Neither subsumes the other.

DEFAULT OFF. A mis-set threshold makes a node read "busy" on noise and stop
transmitting entirely, which is worse than the bug, so it must be tuned on hardware
before it ships live. Compiled out unless LORA_RSSI_LBT_MARGIN_DB is defined at
build time; when off it is a compile-time `return false` (zero behaviour change).
Fails open: returns not-busy unless in RX with a full noise-floor window and a sane
dBm reading, so it can never persistently silence a node.

Native build (gate off) links clean.

* LoRa LBT: RSSI margin profiler to tune RSSI_LBT_MARGIN_DB (default off)

Instrumentation to pick the #4/#5 RSSI second-gate margin from measured data
instead of guessing. Build with -DLORA_RSSI_LBT_PROFILE; compiled out otherwise.

It accumulates (RSSI - rolling noise floor) in two channel states:
- idle   (reuses updateNoiseFloor()'s existing RX sample, no extra SPI): the noise-
         jitter distribution. Its high tail is the floor the margin must clear.
- signal (decoded-packet RSSI, hooked in handleReceiveInterrupt): the real-traffic
         rise. Its low tail is the ceiling the margin must stay under.
A throttled log dump prints both distributions (min/mean/max + percentiles) and the
derived usable window (idle p99, signal p05).

Placement: the stats/histogram engine is a dependency-free, radio-agnostic header
(RssiProfiler.h) so it stays out of the core file and is testable on its own; the
two hooks and the RSSI/log I/O live on RadioLibInterface where the state is.

Independent of the gate flag (LORA_RSSI_LBT_MARGIN_DB) on purpose: profile first to
choose the margin, then build the gate on. Native build (profiler on) compiles clean.

* LoRa LBT: draft #3/#6 fixes behind MESHTASTIC_RADIOLIB_HAS_RESUME_RECEIVE (inactive)

Firmware side of the CAD->RX handoff (#3) and ISR_RX re-arm (#6) from the LBT
audit. Both need to re-arm RX WITHOUT the standby() that startReceive() forces
(which aborts an in-flight reception) - unavailable in stock RadioLib, provided by
resumeReceive() in NomDeTom/RadioLib@rxResume.

Guarded by MESHTASTIC_RADIOLIB_HAS_RESUME_RECEIVE, left UNDEFINED: against stock
RadioLib these paths compile out and behaviour is unchanged. Define it (via
build_flags) only when linking a RadioLib that has resumeReceive().

- resumeReceiveInPlace(bool startRx): base-class helper - iface->resumeReceive()
  (remap RX IRQ, optional SetRx, no standby) + re-attach the MCU ISR + base RX
  bookkeeping. One place, chip-agnostic via iface.
- #3: SX126x/LR11x0 isChannelActive() CAD exitMode -> GOTO_RX; the TX-decision path
  splits the busy check into rssi/cad flags and, on a CAD detect, hands the packet
  to RX via resumeReceiveInPlace(false) instead of startReceive(). Macro-off, the
  split is exactly the old `channelBusyByRSSI() || isChannelActive()` short-circuit.
- #6: ISR_RX re-arms via resumeReceiveInPlace(true).

Open (flagged in-code, for review + HW validation): whether re-issuing SetRx (#6)
disturbs an on-chip in-flight reception, and the #3 handoff's interaction with a
beacon-target packet on the home config.

* LoRa LBT #4: synthesize GPIO wake cause when light sleep is skipped

doLightSleep() skips esp_light_sleep_start() when a LoRa IRQ is already
asserted, but still read esp_sleep_get_wakeup_cause() unconditionally - so
the skip path returned the previous real sleep's cause (e.g. TIMER) and
missed the ESP_SLEEP_WAKEUP_GPIO branch that sets runASAP. Capture whether we
skipped and return a synthetic GPIO cause in that case so PowerFSM takes the
packet-service path. Reads the ESP-IDF cause only after an actual sleep.

* LoRa LBT #10: keep HEADER_VALID latched in the software IRQ poll

The LORA_DIO1_SOFTWARE_POLL anti-starvation escape hatch cleared both
PREAMBLE_DETECTED and HEADER_VALID whenever a TX was queued. HEADER_VALID is
evidence of a real inbound frame, so clearing it made isActivelyReceiving()
read idle mid-payload and let the queued TX stomp the frame. Gate the hatch on
a bare-preamble IRQ (PREAMBLE set, HEADER_VALID clear) and clear only
PREAMBLE_DETECTED. A stuck header still can't block TX forever - receiveDetected()
ages it out after maxPacketTimeMsec - and readData() clears everything on RX_DONE.

* LoRa LBT #3/#6: CAD->RX handoff + continuous-RX re-arm on stock RadioLib

Reimplements the two audit fixes that previously needed the NomDeTom/RadioLib
@rxResume fork (MESHTASTIC_RADIOLIB_HAS_RESUME_RECEIVE), using only stock
RadioLib, behind a new default-off flag MESHTASTIC_LBT_CAD_TO_RX. Per the
RadioLib maintainer's feedback, no new RX API is needed.

(GOTO_RX) with the RX IRQs pre-mapped in the scan config, so the chip's own
CAD->RX transition delivers RX_DONE with no library call in between. irqFlags
(status-enable) carries the CAD verdict + full RX set incl. PREAMBLE/HEADER so
isActivelyReceiving() can read them; irqMask (DIO trigger) carries the CAD
verdict + terminal RX events only - NOT PREAMBLE/HEADER, which would fire the
ISR mid-frame and run readData() on an incomplete packet. On detection it hands
off in place: clear the latched CAD verdict, re-attach the MCU ISR, mark
receiving - no standby (which would abort the packet just detected).

standby), so re-attach the MCU ISR instead of re-issuing SetRx (which could
disturb a second packet already arriving on-chip).

Removes resumeReceiveInPlace() and the fork macro. SX126x-only: LR11x0's
startChannelScan conflates irqFlags/irqMask (drives the DIO from irqFlags), so
it keeps the safe GOTO_STDBY path, re-arming on detect to stay coherent with
onNotify when the flag is on.

Default-off: needs on-hardware validation and assumes continuous RX (the
default preamble=16/minSymbols=8 degenerates startReceiveDutyCycleAuto to
continuous). Native builds pass both flag-off and flag-on.

* LoRa LBT #1: re-arm RX unconditionally when deferring a busy channel

The post-CAD/RSSI defer path wrapped its startReceive() re-arm in a
!hasTargetRadioSettings(txp) guard, so a beacon-target packet that hit a busy
channel took setTransmitDelay() with the radio left in standby. When the
beacon's target config coincides with the home config the radio is on the home
channel, so the node went deaf on home traffic until the next TX cycle - and
kept skipping the re-arm every cycle the channel stayed busy. Drop the guard:
re-arm unconditionally and keep listening while we wait to key up. A beacon's
job is to get a packet out, but it should still mirror the main RX path.

(No effect under MESHTASTIC_LBT_CAD_TO_RX, where the chip is already left in RX.)

* docs: fix RSSI profiler fences (MD040) + RAM figure, note negative-bin limit

- Tag the formula and sample-output fenced blocks as `text` so markdownlint
  MD040 passes.
- Correct the RAM figure: RssiDeltaStats is 148 bytes (12 scalar + 34*4
  histogram), so two instances are ~296 bytes, not ~280.
- Add a limitations note that all negative deltas collapse into bin[0], so a
  percentile landing there returns the minimum sample. This does not affect the
  margin (keyed off the always-positive idle p99) but can understate signal p05
  when a node decodes below-floor packets; never biases toward a smaller margin.

current positive-only layout (A), a cost-neutral re-centred layout with
negative-range resolution (B, recommended if signal p05 must be trusted),
wider full-range bins (C), more bins (D), and exact/off-box (E). Explains the
current choice and when to switch.

* LoRa LBT: move RSSI profiler + energy second-gate to listening-now-rssi

Split the RSSI work off this branch so the active CAD/sleep fixes and the #3/#6
CAD->RX rework can land without the tuning-dependent RSSI pieces. Removed here
(preserved intact on branch listening-now-rssi):
  - RSSI margin profiler: RssiProfiler.h, the LORA_RSSI_LBT_PROFILE hooks, and
    docs/rssi_lbt_margin_profiler.md.
  - RSSI energy second-gate: channelBusyByRSSI() and the LORA_RSSI_LBT_MARGIN_DB
    gate.

The pre-existing noise-floor sampler (updateNoiseFloor/getNoiseFloor, already on
develop and consumed by telemetry) is untouched. The TX-decision block reverts
to a plain CAD scan; #3/#6 (behind MESHTASTIC_LBT_CAD_TO_RX) and #1 unchanged.
Native build green.

* reduce to bare essentials

* LoRa LBT: calibrate CAD symbol count and detPeak against vendor data

NUM_SYM_CAD carried two incompatible meanings: computeSlotTimeMsec() read it
as a literal symbol count, while the drivers passed it into scanChannel(),
where symNum is a register encoding on SX126x/SX128x. On SX126x the raw 2
encodes CAD_ON_4_SYMB, so the chip has scanned 4 symbols since #5749/#5772
while the slot time was priced at 2.5 - a 1.8x mis-scaling of the CSMA
backoff unit, live since January 2025.

Give the constant one meaning (a literal count of 4) and have each driver
translate at its own call site. getCadSymbolCount() reports the real scan
length so slotTimeMsec matches it; RF95 overrides it because SX127x CAD is
fixed in hardware and its legacy scanChannel() takes no symNum.

AN1200.48 Table 1 recommends 4 symbols for SF9-SF12, which is where most
shipped presets sit, so 4 is the right target. The comment claiming 2 was
reading that note's SF7/SF8 row.

detPeak is calibrated per (SF, symbol count), and on LR11x0 per bandwidth
as well. Both LR drivers ran thresholds meant for a 2-symbol scan, leaving
them less sensitive than measured-best and biased toward missed detections.
Now sourced explicitly:

  LR20x0  LR20xx datasheet rev 2.2 Table 6-19, indexed by symbols x SF
  LR11x0  Semtech SWSD003 lr11xx/apps/cad/main_cad.c optimized_parameters,
          indexed by symbols x bandwidth x SF
  SX126x  RadioLib's SF+13, which sits at or below every AN1200.48 value and
          so errs toward deferring rather than transmitting

Combinations the vendor data does not characterise fall back to the RadioLib
default rather than guessing. LR2021 also pins fastCad, which scanChannel()
reads off the radio object rather than the config struct.

Also fix the 2.4 GHz slot term: (2 * sf + 3) / 32 is integer division that
truncates to 0 for every legal SF, so the AN1200.22 fractional term never
contributed anything.

* LoRa LBT: drop audit-doc pointers and cross-chip asides from comments

The LBT comments referenced an external audit document by item number (#1,
#3, #3/#6, #10, and a see-.notes/lbt pointer), which means nothing to anyone
reading the tree on its own. They also described what sibling drivers do,
which goes stale silently the moment one of them changes and belongs in that
driver's own file anyway.

Keep the reasoning, drop the pointer and the comparison. Where a comment
explained a rule that genuinely spans drivers - NUM_SYM_CAD's register-
encoding caveat - state it as a rule rather than a roll-call of chips.

No behaviour change; comments only.

* LoRa LBT: don't index the LR11x0 CAD table with a 2.4 GHz bandwidth

The detPeak lookup picked its bandwidth row by range, so wideLora's 406.25 kHz
fell into the sub-GHz 500 kHz row - SWSD003's table is the sub-GHz LoRa modem
(BW enums 62.5-500), and 2.4 GHz is a separate modem with its own calibration.
Match the four bandwidths exactly instead, so anything unmatched falls back to
the RadioLib default rather than borrowing a row it has no claim to.

Those four are the whole sub-GHz set today - LR11x0::setBandwidth() rejects
anything else - so note that a newly unlocked bandwidth, or a symbol count
outside 2/4/8/16, needs a row adding here and fails silently if it doesn't get
one. Same note on LR20x0 for symbol counts above 4.

Also correct two citations. The 2.4 GHz slot term is the SX1280 datasheet's own
CAD duration formula, and the CAD symbol-count guidance is AN1200.77, not
AN1200.22 - which is "LoRa Modulation Basics" from 2015 and predates the part.
Record that SX1280 ignores detPeak/detMin/exitMode entirely: SetCadParams
carries only cadSymbolNum, and the PNR threshold lives in register 0x942.

* LoRa LBT: set the SX1280 CAD PNR threshold and scan 8 symbols

SetCadParams on this part carries only cadSymbolNum - detPeak/detMin in the
scan config are inert - so CAD sensitivity is governed entirely by register
0x942, which nothing was writing. The scan therefore ran at the chip's reset
value of 0x32, against the 19-36 that AN1200.77 Table 1 calibrates per SF and
bandwidth: at LONG_FAST wideLora the recommendation is 27 and we were using 50.
A threshold that high needs a much stronger correlation peak, so 2.4 GHz LBT
was under-detecting on top of the symbol-count bug already fixed.

Write the table value before each scan, indexed by bandwidth x SF. Unmatched
bandwidths write nothing and leave the chip's default, as on the LR parts.

This goes through our own Module rather than lora.writeRegister(), which
RadioLib keeps protected unless RADIOLIB_LOW_LEVEL unlocks raw register access
across every driver. SX128x::writeRegister() is a straight SPIwriteRegisterBurst
on the same Module we already own, and begin() has pointed spiConfig at the
0x18 WriteRegister opcode long before any scan runs, so the transaction is
identical - no subclass needed.

Also raise the CAD window from 4 to 8 symbols, matching RadioLib's own SX128x
default. AN1200.77 measures a longer window as moving P(Detection) further from
P(False Detection); its thresholds are stated to hold for any window duration,
so the table above is unaffected. NUM_SYM_CAD_24GHZ moves in step so the slot
time still reflects the real scan.

Not hardware-verified.

* LoRa LBT: hand CAD straight to RX on the LR parts

CAD exited to standby, and the busy-channel path then issued a full
startReceive() - which standbys the radio and re-enters RX from scratch,
throwing away the reception CAD had just detected. Both LR families expose a
CAD-to-RX exit mode that avoids the round trip, and it reaches the chip through
the public startChannelScan(cfg), so nothing here needs a library patch.

A note in an earlier commit claimed this was impossible because RadioLib
collapses irqFlags and irqMask into one set. That reasoning is SX126x's, where
irqMask is a status gate and an event omitted from it never latches at all.
The LR parts have no such gate: SetDioIrqParams takes a mask per interrupt pin
and SetDioIrqConfig maps IRQs to one DIO, while getIrqStatus() reads the status
bytes returned on every SPI transaction and consults no pin mapping. So the CAD
IRQ set now carries the verdict plus terminal RX events only - preamble and
header stay off the pin, where they would fire the ISR mid-frame and run
readData() on a partial packet - and isActivelyReceiving() still sees them.

rearmReceive() cannot be unconditionally standby-free the way SX126x's is.
cad_timeout 0 means "RX until one packet arrives, then standby", so the two
re-arm paths leave the chip in different states: already listening after the
handoff, back in standby after that packet's RX_DONE. It branches on a flag set
at detection and cleared on use, so the first re-arm skips the standby and the
next restores continuous RX. Forcing continuous RX through the timeout instead
is not reliable - RadioLib converts it to RTC ticks through a float divide, so
the 0xFFFFFF "no timeout" encoding is not addressable.

On a CAD false positive the chip now waits in single-shot RX rather than
returning to standby. Still listening, but a state the old code never entered.

Not hardware-verified.

* LoRa LBT: size the 2.4 GHz CAD slot per chip, not per band

computeSlotTimeMsec() branches on myRegion->wideLora, which is a region rather
than a part. LR1120 and LR2021 both run there, and both scan NUM_SYM_CAD
symbols - but that branch read the flat NUM_SYM_CAD_24GHZ, so raising it to 8
for SX128x moved the slot for two families whose scan never changed. At
LONG_FAST wideLora that priced ~22 ms of CAD against a ~10 ms scan.

getCadSymbolCount() exists precisely so the slot tracks the real scan, but only
the sub-GHz branch consulted it. Use it in both, and give SX128x an override
returning NUM_SYM_CAD_24GHZ. That constant stops being a fleet-wide 2.4 GHz
value and becomes what one driver reports; SX128x is unchanged at 8.78 symbols,
while the LR parts on 2.4 GHz drop from a wrong 8.78 to 4.78.

The error was conservative - slots too long, so throughput lost rather than
collisions caused - but it is the same scan/slot mismatch the rest of this work
removes.

* LoRa LBT: declare CAD symbols per chip and per band, 8 on 2.4 GHz

A 2.4 GHz region is shared: an LR1120 and an SX1280 can sit on the same mesh.
Leaving the LR parts at 4 symbols there while SX1280 scanned 8 gave them
different slot times, and so a different CSMA backoff scale between neighbours
- the cross-family asymmetry this branch removed for sub-GHz, reintroduced one
band up. Both LR families now scan 8 on 2.4 GHz, matching SX1280.

Rather than switch on the band inside a shared constant, each driver states its
own count for each band it works in, and derives the symNum it passes from the
same accessor - so the scan and the slot cannot drift apart:

  SX126x   4 sub-GHz
  SX128x   8 on 2.4 GHz
  LR11x0   4 sub-GHz, 8 on 2.4 GHz
  LR20x0   4 sub-GHz, 8 on 2.4 GHz
  RF95     2 sub-GHz, its CAD being fixed in hardware and not settable

NUM_SYM_CAD and NUM_SYM_CAD_24GHZ become base-class defaults nothing falls
through to; they now record the fleet convention rather than any part's
behaviour.

LR20xx Table 6-19 stops at 4 symbols, so an 8-symbol scan reuses that row -
the last measured point, erring high and so slightly less sensitive than a
true 8-symbol value. Noted at the table.

Also a comment pass over the branch: drop retrospective phrasing that describes
what the code used to do, cut trailing justification clauses, and fix comments
the per-band change left stale - one still claimed the LR parts scan fewer
symbols than SX1280 on 2.4 GHz, which is now the opposite of the truth.

* LoRa LBT: sweep up a CAD->RX handoff that delivers nothing

A handoff leaves the chip listening by its own exit mode, so nothing in the
driver arms the radio and no return value says whether it worked. If the
detection was false, or the exit mode was not honoured, the node waits in a
state we never verified - and on the LR parts that is single-shot RX, which
does not return to continuous listening on its own.

Stamp the handoff and let the existing ~1s poll re-arm if a whole max-length
airtime passes with no packet, the same bound receiveDetected() uses. Clearing
it on a real RX_DONE is obvious; clearing it in startSend() is not, but a TX
can intervene before any packet arrives and its completion re-arms RX anyway,
so leaving the marker set would have the poll re-arm a radio already listening.

Reads the clock through Time::getMillis(), the same source Throttle compares
against, so the site stays testable across the millis() wrap. 0 is the
"none outstanding" sentinel and is tested before the elapsed compare.

Also document on rearmReceive() that an override must never call the chip's own
startReceive() - its standby+SetRx aborts the packet CAD just detected, which
is the entire reason the override exists.

* define txen pin to allow sx128x testing

* LoRa LBT: bound the CAD->RX handoff in hardware, and re-arm after it delivers

cadTimeout only applies to the CAD->RX exit mode. Every driver on develop
exited CAD to standby, so the field was ignored and its value - 0, which no
datasheet defines - was dead data. Switching the exit mode to RX made it
load-bearing while the line itself never changed, so the diff showed nothing.

All three handoff parts now bound that RX at one max-length airtime, taken
from getPacketTime() so it tracks the preset. A detection that delivers
nothing expires to standby and raises TIMEOUT, already mapped to the pin, so
the existing ISR re-arms and the queued TX retries on its own backoff.
handleReceiveInterrupt() returns early on TIMEOUT without RX_DONE; otherwise
each dud detection would reach readData() and be logged as a bad packet.

That RX is single-shot, so the arm after it delivers must be a full one.
SX126x re-armed unconditionally without a standby, which left the chip in
standby while the interface believed it was listening - and nothing swept it,
since RX_DONE has already cleared the handoff stamp. A node that received a
handoff packet then went deaf until its next transmit. It now carries the
same cadHandedToRx flag the LR drivers already had.

Sourcing, since the parts disagree and RadioLib's uniform ChannelScanConfig_t
hides it: SX126x DS_SX1261-2 p98 (15.625us steps), LR11x0 UM Table 8-8
(31.25us), LR2021 lr20xx_driver cad_timeout_in_pll_step (31.25us, contra the
datasheet's "32 MHz periods"). RadioLib scales both LR parts as 30.52us, so
the programmed value lands ~2% long - harmless, and left for upstream.

Also marks the three SWSD003 cells at 2 symbols/BW500/SF10-12 as that SDK's
fallback rather than measurements.

* LoRa LBT: own the CAD->RX handoff in one place, and void it on standby

The handoff state was split across two classes: cadHandoffRxStart in
RadioLibInterface, cadHandedToRx in each of SX126x/LR11x0/LR20x0, whose
rearmReceive() overrides were byte-identical. Neither field was cleared by
setStandby(), so a standby taken while a handoff was outstanding could strand
cadHandedToRx set - and the next rearmReceive() would then re-attach the ISR to
a chip sitting in standby, marking the interface as receiving with no RX_DONE
ever to come and no recovery path. A stale cadHandoffRxStart was milder but
still re-armed the radio over whatever was arriving at the time.

Hold both in the base, arm them together in noteCadHandoffToRx(), clear both in
setStandby(), and collapse the three overrides into one non-virtual base
rearmReceive(). SX128x and RF95 never arm the flag, so they keep taking the
plain startReceive() branch. Document on isChannelActive() that a true return
must be followed by rearmReceive() - the invariant the whole scheme rests on.

Two fixes fall out of the shape:

- The handoff re-arm attaches a rising-edge ISR to a line that is not known to
  be low, unlike startReceive() which clears the IRQ status first. Follow it
  with checkRxDoneIrqFlag(), as startReceive() already does.

- checkCadHandoffTimeout() used one max-length airtime, the same figure the
  chip's own cadTimeout now uses, so the two expired together. Losing that race
  left a queued ISR_RX to run against flags the software path had just cleared,
  falling past the TIMEOUT guard into readData() on an empty buffer. Double it
  so the hardware always expires first; the backstop then only covers an RX
  whose timer stopped on a header that never completed.

* LoRa LBT: re-arm RX when a queued packet is dropped for tx_enabled=false

Pre-existing on develop, not introduced by this branch, but it is the same
failure this series exists to remove. TRANSMIT_DELAY_COMPLETED reaches
startSend() only through isChannelActive(), which leaves the chip in standby
for the transmit about to follow. When that transmit is then dropped because
LoRa TX is disabled, the early return frees the packet and returns without
arming anything: isReceiving stays false, so pollMissedIrqs() skips the radio
too, and the node is deaf until something else re-arms it.

Narrow - tx_enabled has to change between enqueue and dequeue, since send()
checks it as well - but the fix is one call on a path that already exists.

* LoRa LBT: say what the CAD slot time actually does per chip

Two comments in RadioInterface.h described intentions the code does not carry
out.

NUM_SYM_CAD/NUM_SYM_CAD_24GHZ claimed the per-band values keep the CW backoff
scale equal across a mesh. They do not: the slot has to match the scan each part
really runs, and RF95's CAD is fixed in hardware at 2.25 symbols while
SX126x/LR scan 4. A mixed sub-GHz mesh therefore runs two slot lengths, which
is correct per part and worth stating rather than implying otherwise.

The slotTimeMsec initializer runs during RadioInterface's own construction, so
the virtual getCadSymbolCount() it calls always resolves to the fallbacks here,
never a driver override. That is harmless only because applyModemConfig()
recomputes it before anything reads it - left as-is deliberately, since
initializing to 0 would make random(0, 2^CW) * slotTimeMsec fire an immediate
transmit if anything ever did read it early.

* LoRa LBT: set the SX128x CAD threshold at config time, not per scan

isChannelActive() looked up the AN1200.77 PNR row and wrote register 0x0942 on
every scan, but sf and bw only change in applyModemConfig(). That is an SPI
round trip between the channel scan and the transmit that follows it, on the
one path this file's own comments ask to keep short.

Move it to applyCadDetPeak(), called from reconfigure() after the sf/bw setters
it depends on, and from init() as well - init() does not route through
reconfigure(), so it needs its own call.

* ESP32: stop skipping light sleep forever on a stuck LoRa IRQ

The skip added earlier in this series returns instead of sleeping whenever
DIO1 already reads high, so the main loop can service the packet rather than
strand it for the sleep chunk. It had no bound: a line that latches high with
nothing clearing it makes every subsequent call skip too, and the node quietly
stops sleeping at all, announced only by a LOG_INFO each time.

Count consecutive skips - warn at 3, sleep through at 5, reset on any real
sleep. If the IRQ has survived five attempts the main loop is not going to
clear it, and never sleeping costs more than one stranded packet.

Also drop the LORA_DIO1_EXTENDED_IO branch in loraWakeIrqAsserted(): those
boards return from doLightSleep() before it is ever called.

* nrf52 promicro: gate the P1.06 TXEN pin, and add an optional SX1280 build

P1.06 was wired to SX126X_TXEN unconditionally earlier in this series, to drive
an external PA on a bench unit. That is not safe to ship: three envs share this
variant.h, and P1.06 is PIN_WIRE_SCL on the EasyProMicro pinout and
PIN_EINK_BUSY on the InkHUD one. The default builds go back to RADIOLIB_NC.

Put it behind -D PROMICRO_SX126X_TXEN, refused wherever the pin is already
claimed. The EasyProMicro arrangement has its own SX126X_TXEN on P1.00 in the
#else branch and never reaches this, so only the e-ink exclusion is needed.

The pin was wanted for SX1280 in the first place - every other SX128X line is
already assigned on this board and TXEN was the one missing - so add that too,
behind -D PROMICRO_SX1280 and a new nrf52_promicro_diy-sx1280 env. Both opt-ins
claim P1.06, so asking for both is an #error rather than a silent pick.

Costs about 10.7 KB: the image ends at 0xE5140, 19 KB clear of the warm region,
against 0xE2710 and 30 KB for the base env.

* LoRa LBT: fix two defects in the CAD->RX handoff found in review

Both reported by Copilot against 1fcd219af, both confirmed against the code as
it stands after the handoff was hoisted into RadioLibInterface.

rearmReceive() armed the MCU ISR before marking the interface as receiving. An
ISR firing in that window queues ISR_RX while isReceiving is still false, so
handleReceiveInterrupt() bails with "called while not in rx mode" and the packet
is dropped - the exact packet the CAD handoff existed to catch. Reversed, which
also makes this path match the order the drivers' own startReceive() has always
used: base state, then arm, then checkRxDoneIrqFlag().

noteCadHandoffToRx() stored Time::getMillis() raw, but 0 is the "no handoff
outstanding" sentinel that checkCadHandoffTimeout() tests before its elapsed
comparison. A handoff armed on the one millisecond per wrap where getMillis()
returns 0 reads as "none outstanding" and the backstop never fires. Step past
it to 1, the same hand-remap Throttle.h's own TODO records GPS.cpp using for
fixHoldEnds. One millisecond of error, once per 49.7 days.

* ESP32: wake on SX128X_DIO1, which five SX1280 boards define instead of LORA_DIO1

enableLoraInterrupt() only ever looked at LORA_DIO1 and RF95_IRQ. RadioInterface
builds an SX1280Interface from SX128X_DIO1, and several variants name the IRQ
pin only that way, or put it on a different pin from LORA_DIO1:

  tlora_v2_1_18          LORA_DIO1 undefined      SX128X_DIO1 26
  betafpv_2400_tx_micro  LORA_DIO1 undefined      SX128X_DIO1 4
  t-eth-elite            LORA_DIO1 16             SX128X_DIO1 8
  tlora_t3s3_v1          LORA_DIO1 33 // TCXO_EN? SX128X_DIO1 9
  tlora_t3s3_epaper      LORA_DIO1 33 // TCXO_EN? SX128X_DIO1 9

Every branch of the function is gated on defined(LORA_DIO1), so on the first two
it preprocessed to an empty function: esp_sleep_enable_gpio_wakeup() still
enabled GPIO as a wake class, but no pin was ever armed for the radio. On the
other three it armed the wrong pin - GPIO33 there being the line the variant's
own comment questions as TCXO_EN. Those boards could not be woken from light
sleep by an incoming packet; they waited out the 30s chunk and pollMissedIrqs()
recovered the latched RX_DONE about a second after waking. Delayed, not lost,
but deaf for the duration.

loraWakeIrqAsserted(), added earlier in this series, inherited the same blind
spot and was dead code on the two boards with no LORA_DIO1 at all - so the
skip-the-sleep fix never once fired on an SX1280.

Resolve the pin per radio in loraWakeDio1Pin() and use it for arming, polling
and teardown alike, so the three cannot drift apart again, and widen their
guards to accept either macro. Behaviour is unchanged wherever it already
worked: for any non-SX1280 radio the helper returns LORA_DIO1, including on
RF95 boards where the SOC_PM_SUPPORT_EXT_WAKEUP branch arms it regardless of
radio type. LORA_DIO1_EXTENDED_IO still short-circuits first.

Note this is a power-profile change for those five boards, not only a fix: they
gain a LoRa wake source they have never had, so on a busy channel their light
sleep will now be cut short by traffic like every other board's.

* LoRa LBT: trim three-line comments to the repo's two-line limit

copilot-instructions.md:340 says one or two lines; the P1.06 availability note
and the LR2021 DIO routing note were both three. CodeRabbit flagged both.

* LoRa LBT: trace the CAD scan, its exits and the handoff outcome

Eight short lines, all in the base class so they cost one set of strings
rather than one per chip driver. The scan logs arm/busy/free; the in-chip
GOTO_RX handoff logs started, then exactly one of pkt, empty, timeout or
void - so a dropped or double-counted handoff is visible by inspection.

void and timeout are LOG_WARN because both mean an invariant broke: a
standby discarded a live handoff, or the chip's own timer failed to fire
and the software backstop had to re-arm. The rest are LOG_DEBUG, so a node
at normal log level stays quiet unless something is actually wrong.

The two pre-existing handoff strings were 44 and 41 bytes of flash; cut to
"CAD>RX timeout" and "CAD>RX empty", they pay for most of the new set. The
shared "CAD" prefix does not dedup - only string suffixes merge - and
splitting it out behind a %s measured 8 bytes worse on Cortex-M once the
extra pointer argument per call site is counted.

Also fixes the delivered-packet trace, which sat above the TIMEOUT check
and so claimed a packet on a window that expired empty.

* LoRa LBT: restore the SX1280 CAD threshold after a chip-state recovery

The calibrated AN1200.77 PNR threshold moved from a per-scan register write to
a config-time one, so it now has to be re-applied wherever the chip's state is
rebuilt. recoverChipStateLoss() hardware-resets the chip and reprograms only
the modem params, which left a recovered SX1280 doing CAD against the vendor
default threshold until the next reconfigure() - and on a node whose config
never changes, that is the rest of its uptime.

* LoRa LBT: retire RX flags that plain RX never completes

Plain RX runs with no chip timeout (startReceiveDutyCycleAuto(16, 8)
falls back to RX_TIMEOUT_INF) and the DIO mask carries RX_DONE only, so
a PREAMBLE_DETECTED, HEADER_VALID or HEADER_ERR that never completes
stays latched until something re-arms RX. On a node with nothing to
send, nothing does. The CAD->RX handoff already has this recovery
(cadTimeout plus checkCadHandoffTimeout()); plain RX had none.

checkStaleRxFlags() is its twin on the ~1 s pollMissedIrqs() tick. It
notes when flags are first seen, and if no RX_DONE has consumed them one
max-length packet later:

- a header (valid or errored) re-arms RX. RX_DONE clears every flag in
  readData(), so a header still latched has no frame behind it. SX1280
  DS rev 3.3 section 16.2: a header error leaves RX wedged with no
  RX_DONE or timeout, and only a re-arm recovers it.
- a bare preamble is only cleared. ClearIrqStatus/ClearIrq changes the
  IRQ register alone on SX126x, SX1280, LR11x0 and LR20x0, so it never
  aborts a reception; startReceive() goes through standby and would.

HEADER_VALID is never cleared on its own: RadioLib's readData() reads
it at RX_DONE, and on LR2021 its absence reports the packet as header
damaged.

Skipped while a CAD handoff is outstanding (its own timeout owns that
RX) and while RX_DONE is pending. RF95 opts out: its carrier sense reads
modem status rather than latched flags, and SX127x maps neither
PREAMBLE_DETECTED nor HEADER_ERR.

The decision is staleRxFlagAction() in RadioInterface.h, pinned in
test_radio at both sides of the window and for each action.

* LoRa LBT: hold TX on a seen preamble instead of judging it by a deadline

receiveDetected() declared a bare PREAMBLE_DETECTED false once
2 * preambleTimeMsec passed without HEADER_VALID - about 8 ms at
SF7/BW500. Nothing reads the flags on that cadence: they are latched
status bits, never routed to DIO, and the only reader is the TX path,
once per CSMA backoff (0-56 ms at SF7/BW500). The verdict was usually
reached by a read older than its own deadline, and the queued TX went
out over the frame. Reported in #11933 by @jp-bennett, whose two-node
bench measured own TX a median 43 ms after the verdict, inside a ~102 ms
frame. This branch's longer CAD slot widens it to LONG_FAST: 0-308 ms of
backoff at CWmin against a 262 ms deadline.

A read that sees a bare preamble now clears PREAMBLE_DETECTED and holds
TX for one max-length airtime. The clear touches only the IRQ register
(ClearIrqStatus/ClearIrq on SX126x, SX1280, LR11x0, LR20x0), so it never
aborts a reception. Reads during the hold report busy, so the normal
random backoff still spreads retries, and any RX interrupt ends the hold
early. A preamble that fires again during the hold stays latched, and
the first read after it holds again: a source that keeps triggering keeps
deferring TX, one airtime at a time, while a single stale flag cannot
block it. HEADER_VALID is never cleared here - RadioLib's readData()
reads it at RX_DONE, and on LR2021 its absence reports the packet as
header-damaged - and keeps its one-airtime ageing.

The SX126x software IRQ poll routes its bare-preamble case through the
same hold instead of clearing on every tick while a TX is queued, which
would have released TX before the next read could see a refire.

That poll read the private txQueue directly, so meshnology_w10 - the
only env that defines LORA_DIO1_SOFTWARE_POLL - did not compile.
hasQueuedTx() exposes the one fact it needs.

#11937 addresses the same defect by deferring the verdict when the
previous read was stale; the two conflict in receiveDetected().

* LoRa: re-arm RX before logging the packet that just went out

After TX_DONE the chip sits in standby, deaf, until startReceive(). The ISR_TX
path used to log airtime ("Packet TX") and printPacket() the sent packet
first, which kept it deaf for ~2-5 ms more depending on where the log goes.
Measured on an nRF52 SX1262 bench node: the TX_DONE-to-RX gap drops from
~8.8 ms to ~3.7 ms with USB serial logging (~11.3 to ~6.2 ms with the log
also going to a phone over BLE).

completeSending() is split into detachSentPacket(), which clears sendingPacket
and runs packetReleased() so RX re-arms on the home config, and
finishSentPacket(), which does the airtime, counters, log and pool release.
setStandby() callers keep the combined completeSending().

* SX126x: keep the TCXO powered in standby

RadioLib leaves standbyXOSC off, so standby and the post-TX/RX fallback both
use STDBY_RC, which powers a DIO3-controlled TCXO down. Every SetRx and SetTx
after that first waits out the TCXO start-up delay programmed into the chip
(RadioLib's setTCXO() default, 5000 us). On an nRF52 SX1262 bench node the RX
start after TX_DONE took ~6.0 ms at SF7, SF9 and SF11 alike; with
setStandbyXOSC(true) it takes ~0.95 ms, and the TX_DONE-to-RX gap falls to
~1.1 ms together with the previous commit. The result held across the
periodic AGC reset.

Only boards that drive a TCXO from DIO3 change. The cost is the TCXO and XOSC
current while the chip sits in standby, which the firmware keeps brief;
duty-cycled RX still sleeps, and powers the TCXO down, between windows.

* LoRa: skip the periodic AGC reset while a packet is queued

resetAGC() ends in startReceive(), and trySetStandby() first runs
checkNotification() to drain pending events. With a packet queued that can be
TRANSMIT_DELAY_COMPLETED: CAD passes, startSend() keys up, and trySetStandby()
then puts the chip in standby over the transmission it just started.
completeSending() still reports the packet as sent and counts its airtime.
A bench node logged this twice in 20 minutes; one was a packet's last retry,
so it never went on air.

Skip the reset for this tick when a TX is queued. The queue drains within
seconds, and the reset comes round again on the next interval.

* GPS: re-enable on a LoRa config save only when the region was unset

#10386 keeps the GPS off until a region is set and turns it on when a LoRa
config save sets one. The check never looked at the old region, so a GPS the
probe had disabled ("GPS not detected; not present this boot") was
re-enabled by every LoRa config save, preset changes included, and the probe
ran again. The probe blocks the cooperative main loop: on a bench node with
no GPS fitted, TX_DONE handling stalled by 0.34-0.89 s on 4 of 9 packets
after a preset change, leaving the radio deaf in standby for that long.

* LR20x0: CAD exit to RX is 0x01 on the LR2021

RadioLib (510e00cf) defines RADIOLIB_LR2021_CAD_EXIT_MODE_RX as 0x02. The
LR2021 takes SetLoraCadParams exit modes 0x00 CAD only, 0x01 RX on
detection and 0x10 TX when clear, as the LR11x0 does, and refuses 0x02
with a processing error (-706). With the CAD>RX handoff passing 0x02,
every scan failed before the CAD ran and isChannelActive() reported the
channel clear: on a Seeed Mesh-Tracker X1, 539 scans against live
traffic gave no busy verdict, so the node transmitted with no carrier
sense.

Pass 0x01, and warn when a scan fails rather than reporting it clear in
silence.

* LoRa LBT: take out the preamble hold on a seen preamble

Revert be3bf1f38. receiveDetected() judges a preamble by its two-preamble
deadline again, and the SX126x IRQ poll clears a bare preamble directly.
hasQueuedTx() stays: periodicRadioMaintenance() still uses it.

* SX126x: read the queued-TX state through hasQueuedTx() in the IRQ poll

957fbd3f5 restored the poll's direct txQueue.empty() read along with the
preamble clear. txQueue is private to RadioLibInterface, so meshnology_w10,
the only env that defines LORA_DIO1_SOFTWARE_POLL, no longer compiled.

* SX126x: retry a standby that reports a stale command timeout

After a CAD-to-RX handoff's bounded RX times out, the status byte that
comes back with the next SET_STANDBY still carries command status 0x3
(timeout). RadioLib reports that as RADIOLIB_ERR_SPI_CMD_TIMEOUT although
the chip took the command, so every "CAD>RX empty" was followed by a
failed standby, a failed RX start and a full chip re-init. Send
SET_STANDBY once more on that error; the second one sees a fresh status.

Measured on a CH341 host (SHORT_TURBO): chip re-inits went from 3 to 0,
and all 7 retries returned 0.

* feat(portduino): admin keys in config.yaml, beyond the protobuf's three

meshtasticd can now list the public keys authorized to administer the node
in its own config, as Security.AdminKeys, and list more than the three
config.security.admin_key holds. The host's file is the authority: it is
root-owned, so unlike the persisted protobuf an authorized remote cannot
rewrite it, and applyHostKeys() re-asserts it at boot and after every
remote write of the security config. A key removed from the file loses
access on the next boot instead of lingering in flash.

The protobuf array stays at three. It is not an arbitrary cap: a security
set_config already encodes to ~207 bytes against the 221 a PKC admin
packet can carry (233 payload bytes less 12 of PKC overhead), so a fourth
key would not fit in one admin message on any platform.

Four sites decided who may administer a node, each unrolling
admin_key[0..2] by hand - the PKC gate in AdminModule, the same gate in
DMShell, the is_managed guard, and the admin-key trial decrypt in
Router::perhapsDecode. They now share AdminKeys::isAuthorized(), so a key
source reaches all four at once, and enumeration skips empty slots rather
than trusting admin_key_count.

Each configured key costs one trial decryption per PKI packet from an
unknown sender, so the host list is capped at 16 and duplicates are
dropped. Files in config.d append to the list, one per operator. A key
that is not exactly 32 canonical base64 bytes stops meshtasticd rather
than silently authorizing something else, and --check reports it with its
line instead.

* test(portduino): config-check fixtures for Security.AdminKeys

bin/test-config-check.sh drives a built meshtasticd against the fixtures,
which is the only place the two process-level behaviours here are
reachable: what --check reports, and that a normal boot refuses the file.

A clean two-key list, a key three characters short of 32 bytes, and one
key written as a scalar instead of a list - the last two as errors under
--check and as a non-zero exit on a normal boot, since a truncated admin
key would authorize something other than what was written and a file
whose only key is unreadable would otherwise boot a node nobody can
administer. adminkeys-append/ pins the append-across-config.d rule by
value through --output-yaml, with the first key in config.yaml so the
effective list does not depend on the filesystem's order.

Jonathan BennettandClaude Opus 5 8c0abbd522 feat(portduino): BLE peripheral support via BlueZ for meshtasticd (Raspberry Pi) (#11396)
* feat(portduino): BLE peripheral support via BlueZ for meshtasticd on Linux

Adds the standard Meshtastic BLE service (toRadio/fromRadio/fromNum/logRadio)
to the Linux native target, so a Raspberry Pi running meshtasticd can be
paired and used over BLE like any other Meshtastic device.

Implementation: a new LinuxBluetooth backend registers a GATT application,
LE advertisement and pairing agent with bluetoothd over the org.bluez D-Bus
APIs, using sdbus-c++ (both the 1.x and 2.x major versions, via a small
compat shim - Debian bookworm/Ubuntu 24.04 ship 1.x, trixie/Fedora ship 2.x).
When the sdbus-c++ dev package is absent the whole backend compiles out via
__has_include, the same optional-dependency idiom as the ulfius webserver.

Threading follows the NimbleBluetooth model, simplified: the sdbus event
loop runs its own thread, and all PhoneAPI calls happen on the main thread.
Writes queue to the main loop; reads park the D-Bus reply and are completed
from the main thread after queued writes, so write-then-read clients see
their answer without any busy-waiting.

Enablement is a double opt-in: a new `Bluetooth:` config.yaml section
(Enabled, default false; AdapterId, default hci0) must turn BLE on for the
host, and the regular device config bluetooth.enabled must be on. The
config-check schema and fixtures cover the new section.

Pairing honors config.bluetooth.mode: NO_PIN maps to a NoInputNoOutput
just-works agent; RANDOM_PIN to DisplayOnly with the kernel-generated
passkey shown on screen/log via the existing BluetoothStatus plumbing.
FIXED_PIN falls back to random-passkey semantics with a warning - BlueZ
does not support forcing a passkey. PIN modes enforce
encrypt-authenticated-read/write on all mesh characteristics.

Packaging: install a D-Bus system policy so the meshtasticd user may talk
to org.bluez, add it to the bluetooth group, order the unit after
bluetooth.service, and add libsdbus-c++-dev to debian/rpm/docker/CI deps.

Verified in-container against a mock bluetoothd: registration flow, GATT
tree enumeration, advertisement properties, and a full config download
(ToRadio wantConfig -> 47 FromRadio packets) through the D-Bus bridge.
Real-hardware pairing/notify testing on a Pi still pending.

Known limitations (v1): meshtasticd must be restarted if bluetoothd
restarts; FIXED_PIN degrades to a random passkey; getRssi() returns 0
(same as nRF52).

* fix(portduino): BLE fixes from first real-hardware pass (Pi CM5 + RAK6421)

Findings from testing PR #11396 on a Raspberry Pi CM5 (Pi OS trixie,
BlueZ/sdbus-c++ 2.1 - the v2 compat path) with a RAK6421 HAT and an
Android phone:

- getMacAddr() leaked its HCI socket on every call and never closed it,
  and on failure returned without touching the caller's buffer - which
  getDeviceName() passed in uninitialized. Close the socket on all paths
  and cache the MAC after the first successful read; it cannot change at
  runtime and this now runs on every bluetoothd property read.
- getDeviceName() zero-initializes its MAC buffer, and LinuxBluetooth
  snapshots the name once at setup() on the main thread: the
  advertisement's LocalName getter runs on the D-Bus event-loop thread
  and getDeviceName()'s static buffer is not thread-safe.
- Restore NimBLE-style config-phase packet prefetch (depth 3). The
  initial port answered every FromRadio read with a D-Bus -> main-loop
  round trip, which made the config download noticeably slow; ReadValue
  now answers straight from the prefetch queue on the event-loop thread,
  with NimBLE's safety rules (never in STATE_SEND_PACKETS, writes always
  observed before reads, queue cleared on disconnect).
- Set advertising MinInterval/MaxInterval to 20-100ms (BlueZ >= 5.71;
  older versions ignore the properties). btmon showed the kernel default
  of 1.28s otherwise, and Android's background-connect scan windows are
  sparse enough that tap-to-connect took 8-14s; 20ms is the same floor
  NimBLE uses on ESP32.

Verified on hardware: scan, passkey pairing, connect, config download,
reconnect after bond wipe. Also diagnosed (no code change): the node
identity MAC comes from the RAK HAT EEPROM by design, so the BLE name
suffix follows the HAT rather than the BT adapter.

* fix(portduino): address CodeRabbit review on BLE support

- setBluetoothEnable: handle disable before the config gate, so a running
  BLE stack is always stoppable even after the device config turns
  Bluetooth off underneath it
- getMacAddr: read the adapter configured as Bluetooth.AdapterId instead
  of hardcoding hci0, falling back to hci0 for unparseable names
- systemd unit: Wants=bluetooth.service so bluetoothd is pulled up when
  present (After= only orders, it does not start it)
- debian/rpm: Recommends: bluez as the runtime contract for BLE
- dbus policy: document why the org.bluez rule is destination-wide
  rather than a per-interface allowlist

* fix(portduino): show the BLE pairing code on BaseUI screens

onDisplayPasskey published the passkey to bluetoothStatus and triggered
PowerFSM, but never called screen->startAlert(), so on BaseUI the code only
ever reached the log. BluetoothStatus has no BaseUI consumer -- only InkHUD's
PairingApplet and StatusLEDModule read it -- so a Pi driving a HUB75/OLED
panel showed nothing while BlueZ sat waiting for the user to type a code they
could not see. NimBLE and nRF52 draw it via startAlert(); this adds the
missing half for Linux.

The agent callbacks run on the sdbus event-loop thread while the screen is
owned by the main thread, so the passkey is handed over as a pending flag and
drawn from runOnce(), matching the existing disconnectCleanupPending pattern
rather than reaching into the screen from the event loop.

Dismissed on all four exits, so a stale code cannot stick on an always-on
panel: Paired -> true (newly watched in PropertiesChanged, which previously
only looked at Connected), agent Cancel, peer disconnect (moved out of the
lastGone branch so a peer leaving mid-pairing clears the code even when
another device is still connected), and doDeinit() -- applied inline there
because runOnce() may never be scheduled again after teardown.

Verified on a Pi 5 + BlueZ 5.66 in RANDOM_PIN mode: the code renders on a
HUB75 panel and clears once the phone completes pairing.

setup-native-test landed on develop while this branch was adding

bonds" for a clear that clearBonds() then declined to perform. isEnabled()
is only true after setup() completes, which routes that case to the
warning that says the bonds were left alone.

* style: reformat under clang-format 20

#11909 moved trunk from clang-format 16 to 20, which spaces C-style casts
differently and reindents the comment above the HAS_WIFI block. Both files
are ones this branch already touches, and trunk's fmt linter grades whole
files, so its check fails until they are reformatted. No behaviour change.

* fix(portduino): three BLE config and lifecycle fixes from review

Bluetooth config keys are now assigned individually rather than per section.
loadConfig() runs once for every file in config.d, so reading an absent key as
its default let a later file that named only one of them silently reset the
other: `AdapterId: hci1` alone turned Bluetooth off, and `Enabled: true` alone
dragged the adapter back to hci0. Only what a file actually states should
override what an earlier one set.

A backend that failed to come up is now retried. setup() can leave
linuxBluetooth non-null but disabled - bluetoothd not ready, adapter missing,
policy refusing - and every later enable then called resumeAdvertising(), which
returns immediately while disabled. A transient failure at boot kept BLE off
until the process restarted. doSetup() already opens with `if (enabled) return`
and tears the bus down on every failure path, so calling it again is safe.

Bluetooth.AdapterId is now checked for the hci<digits> form. LinuxBluetooth uses
the value verbatim as the BlueZ object path while the MAC fallback reads only
the leading hciN, so "hci1junk" looks plausible, yields a MAC, then finds no
adapter and BLE never comes up. Covered by a new fixture and suite case, which
is the kind of silent no-op that directory exists to catalogue.

Thomas Göttgens c29bd00971 Rewrite the MQTT region root topic only on the default broker (#11899)
* fix(mqtt): rewrite the region root topic only on the default broker

A region change rewrote any root starting with "msh", on any broker. Custom roots such as msh/home were clobbered, and private brokers had their topics moved even though a regional broker is regional already. An empty root, which MQTT treats as the default, was never updated.

Region changes now go through MQTT::applyRegionRootTopic(), which rewrites the root only on the default broker and only when the root is empty, the default, or a msh/<region> the firmware wrote itself.

* fix(mqtt): parse the broker address before the default-server check

Persist module config only when the root actually changed. Replace a stray NUL byte in the test with the \0 escape.

* fix(mqtt): count the regional roots as the default root topic

ae8dee9582 Fix: MQTT topic not updated when LoRa region changes (#10565)
* Initial plan

* Fix: update MQTT topics when LoRa region changes

When the LoRa region is changed via AdminModule::handleSetConfig,
moduleConfig.mqtt.root is updated (e.g. from msh/US to msh/EU_868)
but the running MQTT instance kept using the stale topic strings
(cryptTopic / jsonTopic / mapTopic) that were set at construction time.

Introduce MQTT::reinitTopics() which:
- resets the topic strings to their base values and prepends the
  current moduleConfig.mqtt.root, and
- disconnects from the broker so the next reconnect re-subscribes
  under the new topic prefix.

Call reinitTopics() from MQTT's constructor (replacing the inline
block) so the logic lives in one place, and call it from
AdminModule::handleSetConfig right after moduleConfig.mqtt.root is
rewritten on a region change.

Add a unit test (test_reinitTopicsUpdatesOnRegionChange) that verifies
both the updated subscriptions and the updated publish topic after a
simulated region change.

* Fix: call mqtt->reinitTopics() on region change via menuhandler

* Format MQTT test with trunk style

* fix(mqtt): drop undeclared jsonTopic refs in reinitTopics()

reinitTopics() assigned to a jsonTopic member that does not exist on this
branch (the MQTT class only has cryptTopic and mapTopic), so MQTT.cpp failed
to compile ("'jsonTopic' was not declared in this scope") and broke every
build that compiles it. Remove the jsonTopic lines so reinitTopics() rebuilds
exactly the topics the original constructor did.

Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>

* refactor(mqtt): simplify reinitTopics and its call sites

* fix(mqtt): rebuild topics in runOnce when the root changes

Replaces the per-call-site reinitTopics() calls. Also keep the device state and node database segments when the EU clamp swaps the region.

* fix(mqtt): refresh topics in onSend when the root changed

Rename the region change test to underscore-separated segments.

80cfa52665 Add zero guards on time calculations where they were missing (#11692)
* time: add skipZero/safeMillis/timerEndsAtMillis helpers

skipZero() steps a millis value past 0, since stored stamps and deadlines
conventionally use 0 for "unset" and the one tick per ~49.7-day wrap that
lands on 0 would otherwise read as never-set.

safeMillis() covers a bare stamp; timerEndsAtMillis(delayMs) covers a
deadline, where the sum is what has to dodge 0 - a non-zero read plus a
delay lands there once per wrap - so it is not safeMillis() + delayMs.

* time: replace hand-rolled zero-dodging with the UptimeClock helpers

PacketHistory rxTimeMsec, EncryptedStorage s_lastFailMillis (stamps), and
SGM41562 lastRefreshMs_ / NextHopRouter learnedAtMsec (ternary stamps) each
hand-rolled skipZero() in place; swap in safeMillis()/skipZero() directly.

HapticFeedback pulseOffAt/delayedPulseAt and GPS fixHoldEnds hand-rolled the
deadline form - millis() + delay, then remap a 0 result to 1 - swap in
timerEndsAtMillis(delay).

No behavior change; each site keeps the value it already computed.

* time: guard the remaining 0-means-unset deadline/stamp writes

rebootAtMsec, shutdownAtMsec, and NotificationRenderer::alertBannerUntil are
all read back with a bare == 0 / != 0 check for 'not scheduled', but every
write site computed millis() + delay (or a bare millis() stamp) with no
guard against landing exactly on 0 - the same wrap hazard skipZero() exists
for, just never applied here.

Route every rebootAtMsec/shutdownAtMsec/alertBannerUntil write through
timerEndsAtMillis()/safeMillis(); RadioLibInterface's reboot-on-stuck-tx
sums an already-captured stamp rather than "now", so it goes through
skipZero() directly instead.

No behavior change outside the ~1-in-2^32 wrap window each site was
already exposed to.

* time: guard three more 0-means-unset deadline writes

ntp_renew (ethClient.cpp), suppressTouchTapUntilMs (Events.cpp), and tx_after
(RadioLibInterface.cpp) all read back 0 as a real state - forced NTP renewal,
no suppress window active, no TX delay armed, respectively - but each arm
site wrote a bare millis()/getMillis() + delay with no guard against the sum
landing exactly on 0.

Route each through Time::timerEndsAtMillis(). No behavior change outside the
wrap window each site was already exposed to.

Refresh the Throttle.h TODO list to note ntp_renew is converted too.

* motion: guard the calibration deadline and use Throttle::deadlinePassed

endCalibrationAt's arm site wrote millis() + calibrateFor with no guard
against landing on 0, the same value finishCalibrationIfExpired()/
drawFrameCalibration() treat as "not calibrating". Route it through
Time::timerEndsAtMillis().

Also swap finishCalibrationIfExpired()'s hand-rolled (int32_t)(now - deadline)
< 0 for Throttle::deadlinePassed(): same wrap-safe comparison the codebase
already provides, without the signed-cast pattern Throttle.h documents as
implementation-defined past INT32_MAX, and it drops the file's last direct
millis() call in favor of the Time:: wrapper the rest of it already uses.

* time: fix Throttle::execute()'s own zero-dodging

Both places execute() writes *lastExecutionMs - the first-ever-run branch
and the regular update - used bare Time::getMillis() with no guard against
landing on 0, which is the exact sentinel this function reads back as
"never run" one line above. A hit there makes the next call re-fire
immediately instead of respecting minumumIntervalMs.

Capture now via Time::safeMillis() once; every use downstream (the elapsed
comparison, the stored value) is then safe by construction instead of
needing the guard reapplied at each write.

* revert some safeMillis cases where overflow is a bad thing

* test(uptime): pin skipZero/safeMillis/timerEndsAtMillis at the wrap boundary

Covers the zero case, an ordinary nonzero value, and a sum that lands
exactly on 0 from a nonzero start - the case timerEndsAtMillis() exists
for, and the one the prior suite had no direct coverage of.

* time: restore the route-health write normalization and put it on one clock

noteRouteLearned()/noteRouteSuccess() lost their `now ? now : 1` normalization,
leaving learnedAtMsec able to store 0 - which getOrAllocRouteHealth() reads as an
ever-growing age, making the slot the first eviction candidate and permanently
stale. Normalize at the write, where the block comment already says it happens,
so every caller is covered rather than just today's two.

Both callers, the two isRouteStale() sites and doRetransmissions() now read
Time::getMillis(), so the stamp and every comparison against it share a clock.
doRetransmissions() goes back to getMillis(): its `now` feeds only comparisons,
never a 0-sentinel field, so skipping zero there only cost accuracy.

* time: read the haptic, InkHUD and calibration deadlines on the write's clock

These three deadlines were converted to Time::timerEndsAtMillis() on the write
side while their reads stayed on millis(), so each spanned two clocks and would
fire immediately or never under an injected test clock. Convert the reads to
match: HapticFeedback::scheduleNext()/runOnce(), the InkHUD tap-suppression
window, and the calibration countdown's read-back of screen->getEndCalibration().

MotionSensor's sampledAtMs is left alone - its write and read are both millis()
and consistent already.

* time: correct the sentinel notes to match what the code actually does

The Throttle.h enumeration claimed the remaining timerEndsAtMillis() callers
"already dodge the sentinel", which reads as a completeness claim the same branch
contradicts: RadioLibInterface's tx_after and activeReceiveStart are both 0=unarmed
and both still arm from bare millis(). Name them instead, so the deadline-type
conversion has the real list. The ntp_renew entry now separates a deliberate 0
("due now", forced at link-up) from a computed one, which is what changed there.

The three TODO(elapsed-stamp) blocks ran four and five lines against the repo's
one-or-two rule, and two of them argued their case wrongly. Throttle.cpp implied
safeMillis() simply doesn't help; in fact neither store is safe on the wrap tick -
the 1 underflows a same-instant read, the 0 re-takes the never-run branch - which
is the symmetry worth recording. PacketHistory.cpp called its dodge "reflecting
the previous pattern" when it is load-bearing: rxTimeMsec 0 means "empty slot"
(PacketHistory.h:21) and insert() drops a record stamped 0 outright, so without it
a packet arriving on the wrap tick is never stored and loses its dedup.

Also picks up trunk fmt's trailing-whitespace fix in Throttle.cpp and the comment
realignment in SGM41562.cpp that this branch's added comment knocked out.

* test(nexthop): pin the route-health stamp against the 0 sentinel

The uptime suite covers skipZero/safeMillis/timerEndsAtMillis themselves, but
nothing covered a call site, so the branch deleted noteRouteLearned()'s
normalization and stayed green. None of the existing route-health tests pass 0 as
`now` - they use 1000, learnAt, or millis() - (TTL + 5000) - which is exactly the
gap the regression went through.

Both new tests fail with "Expected 0 to be not equal to 0" when the skipZero() is
backed out of NextHopRouter, and pass with it. noteRouteSuccess() only refreshes
an existing record, so its twin learns a route first to reach the write.

Also drops a self-referential assertion in the uptime suite: comparing
getMillis() against safeMillis() passes even if safeMillis() does no dodge at
all, so it now asserts the literal.

* discard safemillis for skipzero (better semantics and therefore maintainability) and make consistent use of getmillis where it is called (to permit testing)

* more wrapzero safety

* STM gets some too

* time: stop the next 0-means-unset deadline being armed from raw millis()

The fields this branch armed through Time::timerEndsAtMillis() / Time::skipZero()
are the kind that get added by copy-paste: `rebootAtMsec = millis() + N` appears
at twenty-odd sites across six files, and the next module to defer a reboot will
be written from one of them. Nothing catches the mistake afterwards - the sum
lands on 0 for one tick per ~49.7-day wrap, so a test run, a soak and a bench
session all pass while a pending reboot, shutdown, DFU jump or banner expiry is
silently dropped.

Two guards, at the two places it can go wrong.

The helpers themselves: skipZero() is constexpr, so its contract is now pinned by
static_assert in the header rather than only by test_uptime_clock. The asserts are
chosen against the two plausible rewrites - `ms | 1` perturbs every even value and
`ms + 1` turns the last tick of the wrap into the 0 the function exists to avoid.
Both compile, and both pass a test that only checks skipZero(0); each trips a
distinct assert here, naming the failure mode.

The call sites: bin/lint-unset-sentinel-millis.sh flags a sentinel field in src/
assigned from a raw millis()/getMillis() read, and names the helper to use. It is
name-driven because the 0 contract is declared in src/main.h and enforced in six
other files, so no single-file scan can infer it; every one of the thirteen fields
was checked to actually test against 0 before being listed. nagCycleCutoff and
LinuxJoystick's nextRepeatX/nextRepeatY are deliberately absent - their unset state
is a separate bool - and the nine remaining `millis() + x` sites in src/ are locals
that never store 0 for anything to misread.

Blocking, unlike its note-level neighbours: there is no run-time enforcer to pair
with, and the tree has zero violations today, so gating costs nothing. Scoped to
src/ so test_uptime_clock can keep building raw wrap values on purpose.
bin/test-lint-unset-sentinel-millis.sh pins the scanner against 23 fixtures -
reads, disarms, shadowing locals, comments, string literals and the already-fixed
forms all have to stay quiet.

* time: guard the four 0-means-unset stamps this branch had missed

Sweeping src/ for the `if (stamp && <deadline check>)` idiom - the shape that
makes 0 mean "unset" - turned up four stamps still armed from a raw clock read,
so the new lint rule would have had to either ignore them or go red on checkout.
Each is the same one-tick-per-wrap hole the rest of the branch closes:

  * TrackballInterruptBase lastInterruptTime, armed in all four ISR handlers and
    explicitly disarmed to 0 at the threshold reset. getMillis() is the ISR-safe
    read by construction - it compiles to millis() outside PIO_UNIT_TESTING - and
    skipZero() is pure, so neither adds anything to interrupt context.
  * NeighborInfoModule lastSentReply, read as `if (lastSentReply && ...)` before
    the 3-minute reply throttle. Needed the UptimeClock.h include.
  * PositionModule lastSentReply, same throttle; already on the injectable clock
    but still missing the guard.
  * NodeDB lastSort, whose own read spells the sentinel out as `lastSort == 0 ||`.

On the wrap tick each would read as never-stamped: a trackball debounce window
lost, a neighbour or position reply sent inside the throttle it was meant to
respect, one extra NodeDB sort. Cheap individually, which is why they were missed.

All four are now listed in bin/lint-unset-sentinel-millis.sh, so the rule covers
every field in the tree that actually tests against 0 rather than a subset, and
the header records the eight stamps left off for the opposite reason - their unset
state is a separate flag (isNagging, busyTx, heldX/heldY, formatted_this_boot,
heartbeat, gotwind, haveSample, lastIaqValid), so 0 is a value they may legally
hold. The rule is silent across src/ on this tree.

Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

* lint: let a site opt out of the sentinel rule, with its reason on the record

The rule is blocking, so it needs an escape hatch for the site where 0 genuinely
is a legal timestamp - and the hatch should cost something, or it becomes the
first thing anyone reaches for. `unset-sentinel-ok: <reason>` in a comment on the
write, or on a comment line above it, suppresses that one statement:

  // unset-sentinel-ok: busyTx carries the armed state, so 0 is a legal stamp here
  lastTxStart = Time::getMillis();

The reason is mandatory. A bare `unset-sentinel-ok`, or a colon with nothing
after it, is reported instead of honoured - with a message saying so - so the
only way to silence a site is to write down why it is safe. trunk-ignore still
works, but this states the justification at the write and also applies when the
script runs outside trunk.

The marker is read from comment text collected during the same character-level
pass that strips comments and literals, not by re-scanning the raw line. That is
what keeps it out of reach of data: LOG_DEBUG("unset-sentinel-ok: ...") mutes
nothing, because a string literal is not a comment. It is also consumed by the
statement it was written for, so it cannot leak onto the next write - while still
carrying across any number of intervening comment lines to the statement below,
which is where a real justification wants to be written.

Twelve fixtures added for the new behaviour: both comment styles, block and
multi-line block comments, the bare form, the marker-in-a-string cases, and three
leak cases. 35 total, all green, under bash 3.2 as well.

Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

* lint: watch the separate-flag stamps too, with their exemption stated at the write

The nine stamps whose armed state lives in a companion boolean were previously
just absent from the rule's list, which meant the reasoning for leaving them out
existed only as prose in a shell script. They are now listed and individually
opted out at the write, naming the flag that actually carries the armed state:

  // unset-sentinel-ok: haveSample carries the armed state, so 0 is a legal stamp
  lastSampleMs = Time::getMillis();

The point is what happens later. If someone rewrites `if (haveSample && ...)` as
`if (lastSampleMs && ...)`, the field has silently acquired the 0 contract; with
the opt-out sitting at the write, the claim to re-examine is in front of whoever
makes that edit instead of buried in bin/.

Every exemption was checked against its real read sites before being written, and
three candidates did not survive that check. They stay off the list, because
listing one would mean stamping an opt-out over a claim that does not hold:

  * nagCycleCutoff. handleInputEvent reads `if (nagCycleCutoff != UINT32_MAX)`
    without consulting isNagging, so at that read the field is its own armed flag
    with UINT32_MAX as the sentinel - and the arm at ExternalNotificationModule
    .cpp:521 can land exactly there. skipZero() cannot help: it lifts 0 to 1 and
    leaves UINT32_MAX alone, which UptimeClock.h's own static_assert pins. There
    is also a live boot-state bug behind this - the in-class initializer is 1
    while isNagging starts false - and fixing the read is a behaviour change that
    belongs in its own PR.
  * TouchScreenBase::_start. Overloaded as an event stamp AND a `+ 30000`
    suppression deadline compared by signed subtraction, so a near-zero value
    reads as "long ago" rather than "armed 30s out" and LONG_PRESS re-fires.
    skipZero() does not fix this one either: 1 reads as long-ago exactly as 0
    does. It needs the stamp and the deadline held separately.
  * StoreForwardModule::retry_delay. No reads at all today, so nothing misbehaves
    yet; exempting it now would pre-approve the raw arm for whoever implements the
    retry its own comment promises.

The rule is silent across src/ on this tree, and the header records all three
rejections so the next person does not have to re-derive them. The self-test's
negative fixture no longer uses nagCycleCutoff as its example of a safely
unlisted field - that would have encoded the opposite of what the header says.

* fix(time,lint): guard the recomputed tx_after, and judge one write at a time

Two review findings, both real.

setTransmitDelay() recomputes p->tx_after from a clamp of three candidates, and
that recomputation was still raw. Two lines above it, `if (p->tx_after)` is the read
that takes 0 as "no delay wanted", so a clamp landing on 0 drops the CSMA backoff
and the packet goes out immediately instead of after its computed delay. The first
arm site in this function was already guarded; this one was missed because the
value is not a plain `now + delay` and so does not fit timerEndsAtMillis() - it
takes skipZero() instead.

The narrowing order matters here and is spelled out at the site: add_delay is
unsigned long, 64-bit on the portduino host, so the clamp can exceed UINT32_MAX
there. skipZero() on the wide value would pass 0x100000000 through as non-zero and
the store to this uint32_t field would then truncate it back to the 0 being
avoided, so the cast comes first.

The lint rule judged each write by the wrong text. rhs was taken from the write to
the end of the accumulated statement, so a neighbour on the same line decided the
verdict - and it was wrong in both directions:

  rebootAtMsec = millis() + 5; shutdownAtMsec = Time::timerEndsAtMillis(10);
      the later helper call suppressed a genuine raw arm

  rebootAtMsec = otherDeadline; shutdownAtMsec = millis();
      the later millis() reported a safe copy

rhs is now cut at its own semicolon. Six fixtures cover it, including both cases
above, two raw writes on one line, two helper writes on one line, and a statement
split across lines, which must still see its whole right-hand side. 41 fixtures
total, green under bash 3.2.

Garth Vander HouwenandThomas Göttgens 83198c1cbb fix(pki): reject a restored pre-2.8 low-entropy key at set time, explain the swap (#11686)
* fix(pki): reject a restored pre-2.8 low-entropy key at set time, explain the swap

Restoring/setting a private key is a private-key change: the public key is
*generated* from it. The low-entropy blacklist check in generateCryptoKeyPair
runs against the stored public_key at entry, which is empty on a bare key
restore — so a known pre-2.8 weak key derived from the provided private key was
never caught at set time. It was only detected on the next boot (once the weak
public key had been persisted and re-checked), which looks to the user like
their saved key silently "did not stick", and their node number
(== crc32(public_key)) had quietly changed too.

- NodeDB::generateCryptoKeyPair: in the provided-private-key branch, re-check
  the *derived* public key against LOW_ENTROPY_HASHES. If it matches, replace it
  with a fresh secure keypair and set keyIsLowEntropy so the reason is surfaced.
- AdminModule set-config(security): when the restore path regenerated a rejected
  low-entropy key, send a client warning at set time explaining the key can't be
  restored and the node number changed. Scoped to that branch so a stale flag
  from a boot-time regeneration can't fire on unrelated security sets.

No protobuf changes; reuses the existing ClientNotification warning path.

Signed-off-by: Garth Vander Houwen <garthvh@yahoo.com>

* fix(pki): gate low-entropy restore warning on successful keygen

generateCryptoKeyPair returns false on an unset LoRa region before
resetting keyIsLowEntropy, so the set-time warning could fire on a stale
flag. Capture the return value and require both.

Shorten the rationale comments to two lines each.

* fix(pki): clear key sizes when a restored private key derives nothing

The provided-private-key branch sets private_key.size and public_key.size
to 32 before regeneratePublicKey() runs. On failure it returned false with
both sizes still set, and AdminModule persisted that pair; every later
keygen then re-derived from the same dead key. Clear both on the failure
path so the next keygen mints a fresh identity.

Add test_admin_radio coverage for the set-time restore path: a derived
low-entropy key warns and rotates, a stale keyIsLowEntropy flag with
keygen blocked does not warn, and a failed derivation clears both sizes.

* fix(pki): validate a restored public key that is itself blacklisted

A restore supplying both private_key and public_key reached neither keygen
branch, so a whole pre-2.8 low-entropy pair was accepted and persisted at
set time and only caught on the next boot. Re-derive when the supplied
public key is blacklisted, which routes it through the same rejection and
warning as the bare-private-key restore. A non-blacklisted keypair import
is unaffected.

Install the test crypto stub through a helper and drop it in
restoreAdminRadioGlobals(), so a failed assertion's longjmp cannot leak a
freed engine into later tests.

* fix(pki): only warn about a swapped key when one was actually swapped

keyIsLowEntropy is set from the stored public key at function entry, so a
restore whose supplied public key is blacklisted set it even when keygen
merely re-derived the public key from a private key that was kept. The
warning then claimed a new key had been generated and the node number
changed, which was only half true. Gate it on the private key actually
being replaced.

* fix(pki): re-check a freshly minted keypair against the blacklist

Both mint sites called crypto->generateKeyPair() once and trusted the
result, so an entropy source still producing known-weak keys could persist
another blacklisted identity. Route both through a helper that re-checks
and retries a bounded number of times, then logs if it cannot do better.

Pass the caller's own copy of the private key to generateCryptoKeyPair()
instead of config.security.private_key.bytes, which aliased the memcpy
destination inside it.

* fix(pki): fail keygen when every replacement stays blacklisted

generateBlacklistCheckedKeyPair() logged an error after exhausting its
retries but left the compromised keypair in place and its callers marked
the keygen successful, persisting exactly the identity the check exists to
reject. Return a flag, clear both key sizes on exhaustion, and abort both
callers so the next keygen starts clean.

Match the declaration guard to the definition's, and derive the expected
mint count in the retry test from the configured one.

* refactor(pki): drop the keygen retry loop, fail on the first weak mint

Retrying cannot help: an entropy source that lands on one of the twelve
blacklisted keys is broken, and a second call to it produces the same
result. With real entropy the odds are ~2^-250, so the loop never runs
twice in practice either. Check once and fail, which is the same guarantee
in a third of the code.

* fix(pki): check the derived key on the stored-private-key path too

factory_reset_config keeps the private key and clears the public one, so
the entry check sees no stored key, reports "not low entropy" and takes the
regenerate branch, which adopted whatever it derived. A preserved pre-2.8
key was therefore accepted for a whole boot cycle before the next boot
caught it - the same silent revert this PR exists to remove.

Hoist the post-derive blacklist check into a helper and use it on both
derive paths.

* fix(pki): clear key sizes when stored-private derivation fails too

The stored-private-key path set public_key.size to 32 up front and left it
there when regeneratePublicKey() failed, so config claimed a pair the node
never got - the same defect already fixed on the provided-key path.

Both paths now derive through one helper that clears on failure and vets
the derived key, replacing the separate blacklist-replace helper.

Andrew Yong 3c04a79031 fix(stm32wl): improve reboot-to-DFU reliability (#11698)
- In enter_dfu, arm enterDfuAtMsec = millis() + 5s and return instead of
  resetting inline; the want_response ACK then goes out the normal path
  and Power::powerCommandsCheck() calls enterDfuMode() at the deadline.
  Nudge the deadline off 0 in the rare case the addition wraps to it,
  since powerCommandsCheck() reads 0 as unarmed. The delay is the
  client's detach window - and the margin a WebSerial web flasher needs
  (meshtastic/web-flasher#426).
- In enterDfuMode(), stop the GPS and drain/end every configured UART
  before the reset. The ROM bootloader autobauds off the first byte on
  USART1 (PB6/PB7) or USART2 (PA2/PA3), and on every WL variant a
  console UART or the GPS stream sits on those pins. Factor the drain
  into quiesceSerial() and reuse it in cpuDeepSleep().
- Move earlyBootCheck from constructor(101) to .preinit_array, ahead of
  the core's premain()/SystemClock_Config() whatever the link order, and
  reset RCC before jumping to system memory.

The handler used to reset the MCU inline, before the ACK was sent and
while the client still held the console UART. The STM32WL ROM bootloader
autobauds off the first byte received; a stray byte during the handoff
(a trailing protobuf frame, a port-close DTR/RTS glitch) desynced it and
left the device unreachable at any baud until a hard reset.

STM32WL only: every hunk is behind #if defined(ARCH_STM32) or lives in
main-stm32wl.cpp. nrf52, rp2040 and the rest are unchanged.

Known limitation: gps->disable() only issues a UBX sleep command, so a
non-u-blox or otherwise free-running GPS with no hardware enable/standby
pin keeps transmitting on its UART past this point. If that UART is
USART1 (PB6/PB7) or USART2 (PA2/PA3), the ROM bootloader can still
autobaud onto the GPS stream instead of the host. New STM32WL hardware
designs should keep GPS UARTs off those two bootloader-autobaud pins, or
provide a way to power down or hold the GPS in reset before DFU.

Ben Meadors 47db0e3020 fix(admin): don't disable BLE on config paths that never reboot (#11651)
Three places took BLE down and left nothing to bring it back. The nRF52
auto-re-advertise bug masked them by restoring advertising ~1s later; with
that fixed (#11650) the outage is real, lasting until the next PowerFSM
transition - up to screen_on_secs, 10 minutes on a default client.

- restore_preferences passed 1000 to reboot(), which takes seconds, arming
  the reset ~16.7 minutes out instead of the intended ~1s. With BLE disabled
  for a pending reboot the node was unreachable for that whole window. Use
  DEFAULT_REBOOT_SECONDS and disable before arming, matching the factory and
  nodedb reset paths.
- mesh_beacon sets shouldReboot=false but was not in the list that spares a
  variant from the blanket disable, unlike statusmessage. Add it.
- MQTT and Serial disable BLE inside their own case, bypassing the
  transaction check above them. Inside an edit transaction saveChanges()
  defers the reboot, so BLE went down with no restore - reachable today by
  importing a device profile containing either module config.

Build: heltec-mesh-node-t096. Tests: test_module_config 3/3.

Ben Meadors 7afd270f39 Gut beacon send-as-node and consolidate TX onto broadcast_targets (#11646)
* Gut beacon send-as-node and consolidate TX onto broadcast_targets

Two MeshBeaconConfig changes, both against fields that never reached a tagged
release, so there is no migration for existing nodes.

broadcast_send_as_node let a client name a node ID to send beacons AS, rewriting
the packet's `from`. Firmware never applied it - the assignment was commented
out, so `from` was always the local node and the field was a settable, persisted
no-op. It was also unsound as designed: rewriting `from` forges no signature, it
only makes isFromUs() false, so perhapsEncode() skips XEdDSA signing and
receivers get an unsigned packet attributed to another node.

broadcast_on_channel / broadcast_on_region / broadcast_on_preset were a second
way to name a beacon destination alongside broadcast_targets, chosen silently on
whether broadcast_targets was empty. The comments claimed the two were
equivalent; they were not. An inline ChannelSettings carries name and PSK, so
broadcast_on_channel could transmit on a channel absent from the node's channel
table, which channel_index cannot express. That is dropped deliberately - the
channel must exist on the node.

Empty broadcast_targets now synthesises one target on the running preset and
region over the primary channel, matching what the scalar path produced when
left unset, so an otherwise unconfigured node still beacons.

The USERPREFS_MESH_BEACON_ON_* keys go with the fields. A preconfigured build
that still defines one now fails at compile time with a pointer to the
USERPREFS_MESH_BEACON_TARGET_0_* equivalents, rather than silently losing its
beacon channel. The replacement names a channel-table slot, so such a build must
also provision that channel.

MeshBeaconConfig shrinks 324 -> 240 bytes and ModuleConfig 328 -> 244, against
the 512-byte MAX_TO_FROM_RADIO_SIZE ceiling that FromRadio sits 2 bytes under.

The protobufs submodule points at a branch carrying both proto changes; it needs
re-pointing to master once meshtastic/protobufs#1047 and #1048 merge.

* Point protobufs submodule at master now that the beacon protos are merged

meshtastic/protobufs#1047 and #1048 are in master, so drop the temporary
beacon-proto-integration pin. MeshBeaconConfig stays 240 bytes and ModuleConfig
244, unchanged from the integration branch.

The bump also picks up master's unrelated additions: the MESHNOLOGY_W12 and
MESHPAGER_X2 hardware models, and a ground-speed unit correction in Position.

AustinandClaude Opus 5 514b476189 feat(admin): append the optional ham long_name to the call sign (#11612)
* feat(admin): append the optional ham long_name to the call sign

HamParameters gained a long_name field (meshtastic/protobufs#941) that
handleSetHamMode never read, so a client that sent one still ended up with a node
named after the bare call sign. Join it behind the call sign with the "//"
separator hams already use on the air: call_sign "N0CALL" plus long_name "Attic
Heltec" becomes "N0CALL//Attic Heltec". An absent long_name keeps the previous
call-sign-only name, which is what the on-device region picker still sends.

Being cosmetic, long_name stays out of the whitespace-only rejection that guards
call_sign and short_name: a blank one is dropped rather than costing the operator
the whole licensing request over a stray space, which that path would report only
as a LOG_WARN and so would be invisible from the app. The composed name is
finished with clampLongName() rather than a bare sanitizeUtf8(), matching
handleSetOwner and NodeDB: the proto caps the parts at 7 + 2 + 14 bytes, inside
the 24-byte local budget, and clampLongName is the backstop if either cap moves.

Clive BlackledgeandClaude Opus 5 389559bddb fix(NodeDB): re-derive my_node_num when ensurePkiKeys() mints the identity keypair (#11426)
* fix(pki): re-derive NodeNum when setting a region mints the identity key

A node's mesh address is derived from its identity key:

    my_node_num == crc32Buffer(config.security.public_key.bytes, 32)

NodeDB::createNewIdentity() is what establishes that, and NodeDB::
generateCryptoKeyPair() is the only thing that called it.

CryptoEngine::ensurePkiKeys() generates or re-derives the keypair and writes
security.public_key, security.private_key and user.public_key - but never
re-derives my_node_num. Boot-time keygen is suppressed while the LoRa region is
UNSET (generateCryptoKeyPair()'s regionBlocksKeygen guard), so on a fresh device
my_node_num is still the MAC-derived value from pickNewNodeNum(). The user then
sets the region - the stock onboarding flow - ensurePkiKeys() mints a key, and
the invariant is broken.

The node then signs its broadcasts (Router.cpp signs when !pki_encrypted &&
(owner.is_licensed || isBroadcast(p->to))). Every receiver runs
verifyFirstContactNodeInfo, fails crc32Buffer(user.public_key) != p->from, and
drops the NodeInfo. The node's identity beacons are invisible to the mesh.

Nothing reboots to repair it: AdminModule sets requiresReboot = false for LoRa
changes ("All LoRa radio changes apply live via configChanged observer") and
MenuHandler ends at service->reloadConfig(changes).

Four call sites reached ensurePkiKeys():

  1. AdminModule set_config LORA, region first set   (phone app - the common path)
  2. MenuHandler applyLoraRegion                     (on-device region picker)
  3. InkHUD MenuApplet applyLoRaRegion               (schedules a reboot, so it
                                                      self-healed at next boot)
  4. portduino wasm wasm_set_region

The reference implementation was already in the tree: the *licensed* branch of
call site 1, thirteen lines below the broken unlicensed one, calls
nodeDB->generateCryptoKeyPair() (which reaches createNewIdentity()) and widens
the persisted mask with SEGMENT_DEVICESTATE | SEGMENT_NODEDATABASE.

Rather than repeat that at four call sites, the key-mint is routed through one
chokepoint that owns both halves of the identity: NodeDB::ensurePkiIdentity()
calls crypto->ensurePkiKeys() and then createNewIdentity(). It lives in NodeDB
because createNewIdentity() operates on the devicestate/node-DB globals, which
CryptoEngine deliberately does not touch - ensurePkiKeys() takes the security
config and user by reference precisely so it stays free of that dependency, and
it is unit-tested against a standalone CryptoEngine.

ensurePkiIdentity() returns true only when my_node_num actually moved
(createNewIdentity() early-returns when the key is unchanged, so a repeat region
change does not disturb the self entry or force a needless flash write). Callers
use that to widen their save mask; my_node_num lives in devicestate and the self
row moves in the node DB, so both segments must be persisted or the fix would
revert at the next boot. SEGMENT_CONFIG, which carries the key itself, is
already unconditional on all four paths.

The InkHUD reboot is left as-is. It is now redundant for this invariant, but it
covers the rest of that menu's behaviour and a redundant reboot is not a bug.

Adds test_handleSetConfig_persistsUnlicensedFirstRegionIdentity, the unlicensed
twin of the existing licensed test, asserting both the segment mask and
my_node_num == crc32(public_key).

Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

* style(NodeDB): trim identity-recovery comments and guard the WASM nodeDB deref

Two review asks, no behaviour change on any built target.

Copilot flagged the unguarded nodeDB deref in the WASM region setter; it is the
only ensurePkiIdentity() call site that did not check the pointer first.

The rest is comment length. AGENTS.md:83 caps code comments at two lines, and the
identity-recovery comments across the four call sites plus the NodeDB.h doc block
ran to four and six lines. The rationale they carried is in the commit messages
and the PR body, which is where AGENTS.md says it belongs.

The PR's own fix in AdminModule.cpp is deliberately untouched.

* fix(NodeDB): keep the identity move authoritative when the self record cannot be created

createNewIdentity() removes the old node entry and assigns myNodeInfo.my_node_num
before it tries to create the row for the new number. If getOrCreateMeshNode()
came back null it returned false, so the first-region callers left
SEGMENT_DEVICESTATE and SEGMENT_NODEDATABASE out of the save mask.

The number had already moved in RAM at that point, and the freshly minted key
goes to flash under SEGMENT_CONFIG regardless. The next boot therefore reloads
the old number alongside the new key, which is exactly the
crc32(public_key) != my_node_num break this path exists to prevent, reached
through the error branch instead of the happy one.

Rolling the number back is not an option either, since the key has already been
replaced by the time this runs. So the move is now reported as the fact it is and
the missing self record is logged separately; getOrCreateMeshNode() will recreate
that row on the next contact. Reachable when the self record is absent and the
table is full of protected nodes.

Reported by CodeRabbit on #11426.

- Node/packet IDs use the repo's 0x%08x convention in NextHopRouter,
  NodeDB, AdminModule and CannedMessageModule. The sibling log in each
  if/else pair is converted too, so a pair isn't split across two formats.
  next_hop stays 0x%x - it's the last-byte relay hint, not a NodeNum.
- RTC: the read-path and set-path "not found" warnings were byte-identical,
  so the linker deduped them and the log couldn't say which one fired.
  Split into "RTC read:" / "RTC set:". (The four sites live in mutually
  exclusive #ifdef branches, so the RTC family was never ambiguous.)
- SCD4X getAmbientPressure()/setAmbientPressure() logged "altitude", and
  SCD30 getASC() logged "Can't send command" for a read. Both now name the
  operation they actually perform.
- LOG_ERROR already carries the level: ". Error: %u" -> ", rc=%u" (matching
  the existing rc=%d house style) and "Error executing X()" -> "X() failed".
- Typos and wording: "OTA partiton.  (Reason" -> "OTA partition (reason",
  "CST3530 not response ~" -> "CST3530 no response", "Packet received with
  to: of 0" -> "to=0", HostMetrics "Error decoding" -> "Can't decode", and
  the dangling ": " on the NextHopRouter retransmission line.

03e6b80989 Serial config validation (#11339)
* fix(serial): validate serial module config on every platform

AdminModule guarded the serial config validation by architecture but not the
assignment beneath it:

    #if ARCH_ESP32 || ARCH_NRF52 || ARCH_RP2040
        if (!SerialModule::isValidConfig(...)) return false;
        disableBluetooth();
    #endif
        moduleConfig.serial = c.payload_variant.serial;

So on every other platform an admin "set module config: serial" stored a config
the firmware rejects on ESP32. override_console_serial_port combined with
DEFAULT, SIMPLE, TEXTMSG or PROTO is accepted and persisted today.

Two families are affected, for different reasons:

  - portduino/meshtasticd, where the validation did not exist at all:
    isValidConfig was a static member of SerialModule, and that class is inside
    the same architecture guard, so `nm` finds no such symbol in the native
    object.
  - STM32WL (rak3172, wio-e5, CDEBYTE_E77-MBL, russell), where it existed and
    was never called: the class guard includes ARCH_STM32WL and the AdminModule
    call site did not.

Validation is pure config logic with no serial hardware behind it, so it moves
out of the class and out of the guard as a free serialConfigIsValid(). Its only
external references - clientNotificationPool, service, getValidTime - are
already unguarded elsewhere, so it links on every target. AdminModule's include
of SerialModule.h is unguarded for the same reason; the class itself stays
guarded inside the header. Only disableBluetooth() remains architecture-specific.

This changes what meshtasticd and the STM32WL targets accept: a host relying on
the unvalidated path (override_console_serial_port with a mode other than NMEA,
CalTopo or MS_CONFIG) is now rejected, as it already is on ESP32.

test/test_serial has asserted nothing since it was added in 28aeb0f09e
(2025-07-26): its body is behind the same guard, so on portduino it logged a
warning and ran zero assertions while counting as one of the canonical suites.
Enabling it showed the code did not even compile - its designated initializers
list .override_console_serial_port before .mode, which is not declaration order,
and C++ requires that. PlatformIO only builds test/ for the native env, so no
build had ever compiled these lines. Reordered; all nine now run and pass.

Ben Meadors ae16c052d5 Time out an abandoned admin edit transaction (#11254)
begin_edit_settings sets a bool that only the matching commit ever
clears. If the commit never arrives -- the client dropped its link
partway through a bulk config import, or went away entirely -- the
transaction stays open indefinitely, and every later config write from
any client is applied to RAM, acknowledged, and then never saved. The
writes look successful and are visible in get_config, but the node
reverts all of them at the next boot, and only a reboot clears it.

Give the transaction a one minute idle timeout. Each deferred write
restarts the clock, so the window bounds the gap between writes rather
than the length of the edit; a bulk import sends them milliseconds
apart. The next admin message after it lapses retires the transaction,
persisting the segments it had deferred and flushing the warnings it was
holding. The check runs after the auth gates and before the switch, so
every case sees consistent state and the recovery's flash write happens
in the main loop rather than a disconnect callback.

It saves rather than rolls back because there is nothing to roll back
to: each write already took effect in RAM and was acknowledged, so the
transaction only ever deferred the save. That also makes an early expiry
cheap -- the worst case for a client that really was still going is that
its remaining writes are saved individually instead of batched. Closing
on disconnect instead was tempting, but the reporter's captures show iOS
dropping and reconnecting within half a second several times per
session, which would abort imports that currently survive the blip.

Also drops the file-scope hasOpenEditTransaction, shadowed by the class
member at every use site and referenced nowhere else in the tree.

Ben Meadors 5c5cb094e6 fix(admin): stop the admin dispatcher from overflowing the ESP32 loopTask stack (#11239)
AdminModule::handleReceivedProtobuf carried a 3008-byte stack frame - 37% of
the 8 KB Arduino loopTask stack. GCC inlines the eight handleGet* helpers into
it, each of which builds a whole meshtastic_AdminMessage (480 B), so the
dispatcher reserved a slot for every one of them at once even though only one
case ever runs. Two more full AdminMessages lived directly in the function.

That left any admin write short of stack for what runs beneath it:
NodeDB::saveToDisk -> saveProto -> pb_encode -> SafeFile -> LittleFS -> flash.
On heltec-v4 the canary fired at 7824 of 8192 bytes while writing
/prefs/config.proto, so no setting ever persisted and the device rebooted.

Mark the response builders NOINLINE and move the module-API and observer
responses into their own functions. Pure refactor; measured on heltec-v4 the
dispatcher frame drops 3008 -> 384 bytes, taking the crashing path from 368
bytes of headroom to 2992.

* Pin admin responses to the stored peer key and request id

noteOutgoingAdminRequest derived its PKC pin from p.public_key, which nothing
populates on the outgoing path, so keyValid was false for every client request
and the pin never engaged. The accepted-response predicate reduced to an
unauthenticated from plus variant and subtype.

Resolve the destination key from NodeDB the way perhapsEncode does, and pin it
only when the request would actually be PKC-encrypted. Extract that condition
from perhapsEncode as wouldEncryptWithPKC so both use one predicate. Also
record the request's packet id and require the response to echo it.

Resolve conflicts against the NodeDB signer/key primitives (#11050) and the
admin-key PKI decrypt budget (#11100).

- NodeDB: drop this branch's hasSeenXeddsaSigner in favour of develop's
  isKnownXeddsaSigner. They answer the same question, but develop's reads the
  dedicated warm signer bit (warmSignerOf) rather than the WarmProtected
  category, and TrafficManagementModule already depends on it. Keep develop's
  copyPublicKey/copyPublicKeyAuthoritative, isVerifiedSignerForKey and
  commitRemoteKey/KeyCommitTrust.
- checkXeddsaReceivePolicy: keep this branch's Strict/Balanced/Compatible
  policy, which is a superset of develop's balanced-only downgrade gate, and
  call isKnownXeddsaSigner from it. develop's !pki_encrypted term is dropped
  because the policy returns early for PKI packets before that check.
- perhapsDecode: keep develop's key resolution (NodeDB then pending-key, only
  for real PKI candidates) plus its admin-key token bucket, and re-apply this
  branch's pkiAttempted flag feeding the DECODE_OPAQUE verdict. Keep both
  passesRoutingAuthGate and adminKeyFallbackAllowed/Refund.
- test_A17: model eviction the way NodeDB actually does it, passing the warm
  signer bit as well as the XeddsaSigner category, since isKnownXeddsaSigner
  reads the former.

Native suite: 38 suites, 743/743 cases, no sanitizer findings.

Ben Meadors 5cf346311c fix: don't wipe admin keys when regenerating the keypair (#11088)
A client's "regenerate keys" action sends a blank SecurityConfig carrying
only the new private key rather than the config it read from the device,
so assigning it wholesale cleared admin_key, is_managed, serial_enabled,
debug_log_api_enabled, admin_channel_enabled and packet_signature_policy.
Losing the admin keys locks the owner out of remote admin with no recourse
but a physical connection to the node.

Detect that bare-rotation shape and swap in just the keypair, leaving the
rest of the security config intact. Deliberately clearing admin keys still
works through a SET that leaves the private key alone.

* Stop accelerometer thread when double-tap/wake-on-motion disabled at runtime

double_tap_as_button_press and wake_on_tap_or_motion are applied live: the
OFF->ON edge calls accelerometerThread->start(), but there was no ON->OFF
branch, so turning either flag off left the sensor thread running (polling
I2C, drawing power) until reboot. Worse, because enabled stayed true, a later
OFF->ON edge was a no-op (the enabled==false guard blocked re-start), leaving
the feature un-restartable without a reboot.

Add the symmetric ON->OFF branch in both handlers. When a flag goes true->off
and the other consumer of the shared thread is also off, call
accelerometerThread->disable() (stops runOnce polling and clears enabled so a
later re-enable can start() again). Each branch checks the other flag first so
disabling one feature never stops the sensor while the other still needs it.

* Keep accelerometer thread running when its sensor drives the compass

* Guard accelerometer thread config toggles against a null thread pointer

* AdminModule: factor shared accelerometer start/stop into a helper

The device and display config handlers had mirror-image blocks reconciling the
shared accelerometer thread. Extract reconcileAccelerometerThread(wasOn, nowOn,
otherFeatureOn) so the null guard, edge logic, compass (providesHeading) guard,
and rationale live in one place; each call site is now a single call. Behavior
is unchanged. Also drops the redundant per-field assignment that the
whole-struct `config.device = ...` / `config.display = ...` overwrites anyway.

* Use hardware RNG for session passkey and PKC extra nonce

The admin session passkey and the Curve25519 extra nonce were drawn
from Arduino random(), which is not a CSPRNG. Source them from
HardwareRNG::fill, mirroring the signing path, and fall back to the
seeded CSPRNG (CryptRNG) only when no hardware source is available.

* AdminModule: make session passkey expiry rollover-safe

session_time was compared as millis()/1000 seconds with additive
thresholds, which breaks across the millis() wrap and could keep a stale
admin session key valid. Store session_time in millis() and use
Throttle::isWithinTimespanMs for the 150s refresh and 300s validity
windows.

* AdminModule: track session passkey validity with an explicit flag

session_time == 0 was used as the uninitialized sentinel, but millis()
is legitimately 0 in the first millisecond of uptime, so a passkey
issued then would be treated as no session. Use a dedicated
session_passkey_valid flag instead.

* AdminModule: camelCase the session passkey validity flag

Thomas Göttgens 8147970957 AdminModule: only accept admin responses to requests we sent (#11024)
* AdminModule: only accept admin responses to requests we sent

An admin *_response short-circuited the auth and session-passkey checks that gate
every other admin message, so any node could deliver one. On a channel the module
listens to unauthenticated, a get_module_config_response drives the remote-hardware
pin handler with attacker-supplied values.

Track the destination of outgoing admin requests (per remote, with the pinned PKC
key when there is one) and accept a response only from a node with a matching
outstanding request, inside the same window as the session passkey. Local (from == 0)
admin is unchanged; PhoneAPI already gates it.

Also fix the response dispatch: get_module_config_response.which_payload_variant is a
ModuleConfig oneof tag, but it was compared against the AdminMessage ModuleConfigType
enum (different numbering), so the handler never ran. Compare against the oneof tag.

* AdminModule: rollover-safe request window, bind response to request type

Two review refinements to the request/response pairing:

Use Throttle::isWithinTimespanMs for the outstanding-request expiry instead of
comparing millis()/1000 sums, which mis-expired across the millis() rollover.

Bind each accepted response to a request type actually sent to that node. Each
outstanding record now carries a bitmask of the response variants its requests
authorize, so a get_owner request no longer admits a get_module_config response.
The mask accumulates per remote, so a client may still pipeline several request
types to one node and have every answer accepted.

* AdminModule: track admin requests per-request, not per-node

Reworks the outstanding-request table so each request is its own entry with its own
expiry window and pinned key, replacing the per-node bitmask that shared one timestamp
and one key across every response variant.

That sharing let a later request to the same node extend an earlier one's window and,
worse, clear its PKC pin: an unpinned request cleared keyValid, so a plaintext response
to an earlier PKC-pinned request was then accepted. Per-request entries keep each pin
intact. Identical requests are de-duplicated (a client may fetch several config subtypes,
all answered by one response variant) and eviction compares elapsed time, which is
rollover-safe.

Test: a pinned request's response still requires its key after an unpinned request to the
same node.

* AdminModule: match module-config subtype and consume answered requests

Two refinements to the request/response pairing:

Only remote_hardware get_module_config_response mutates state (the pin table), so it
must answer a request for that exact ModuleConfigType, not just any module-config
request. Each entry records the requested subtype and the gate checks it.

A matched request is now consumed on accept, so a node cannot replay a state-mutating
response within the window. Because one request yields one response, request de-dup is
dropped (a client's N indexed get_channel requests are N entries, each consumed once).

Tests: a non-remote-hardware request does not admit a remote_hardware response, and a
second copy of an answered response is rejected.

Andrew YongandBen Meadors b71c1adb26 stm32wl: add hardware RTC support (rak3172) (#10961)
* stm32wl: add hardware RTC support infrastructure

Wires the STM32WL chip's internal RTC (running off the LSE 32.768kHz
crystal) into meshtastic's existing time-of-day framework
(perhapsSetRTC()/readFromRTC()), following the same pattern already
used for I2C RTC chips (RV3028, PCF8563/85063, RX8130CE).

LSE is started and polled manually before ever calling into the
STM32RTC library, with our own bounded timeout - the library's own
internal LSE startup path has no bounded fallback and hangs forever
via Error_Handler() if the crystal never locks, so this is required
for a board with a missing/faulty crystal to boot normally rather
than hang.

Gated behind a new HAS_LSE variant flag (currently unset everywhere,
so this is inert until a variant opts in - see follow-up commit).

* gps: qualify RTC.h includes to avoid case-insensitive filesystem collision with STM32RTC

The stm32duino STM32RTC library (added to lib_deps in a follow-up
commit) ships its own src/rtc.h. On case-insensitive filesystems
(the macOS default), an unqualified #include "RTC.h"/<RTC.h> from
any file outside src/gps/ resolves to the library's rtc.h instead of
src/gps/RTC.h, since PlatformIO's LDF puts lib_deps include paths
ahead of the project's own -Isrc/gps.

Qualify every include as gps/RTC.h so it can't collide with any
same-named header a future dependency might ship, regardless of
filesystem case sensitivity. Purely mechanical, no behavior change.

Ben Meadors 0488a46a3c fix: stop unexpected NodeNum regeneration from PKI key loss (#10808)
* fix: stop unexpected NodeNum regeneration from PKI key loss

A node's NodeNum is derived from its PKI public key
(my_node_num == crc32(public_key)), so it changes only when the keypair is
regenerated -- which happens only when a keygen path runs while
config.security.private_key.size != 32. Two paths could trigger that without
the user intending a new identity:

1. Boot: loadFromDisk() collapsed every non-success loadProto() result for the
   config file into installDefaultConfig() (preserveKey=false), which memset()s
   config and wipes the private key. loadProto() distinguishes DECODE_FAILED
   (file present but undecodable/undecryptable) from OTHER_FAILURE (absent), so
   a transient/corrupt read silently minted a new identity. A new
   configDecodeFailed flag now gates the boot keygen and the boot config-save
   directly (not via region, so it survives the userprefs/region overrides that
   run later in loadFromDisk): identity is frozen, the unreadable file is left
   intact for a later clean boot to recover, and the node boots radio-silent
   (region UNSET, TX off). A genuinely-absent config still gets defaults + keygen.

2. AdminModule security SET: config.security = c.payload_variant.security
   wholesale-clobbered the keypair, then regenerated whenever the incoming
   private_key.size != 32. A client editing an unrelated security field without
   round-tripping the private key would re-mint identity. The existing keypair
   is now preserved when the incoming config omits it; first provisioning and
   key import are unchanged. Intentional reset goes through factory_reset.

Native PlatformIO unit suite (Docker): 499/499 test cases pass.

* test: cover security keypair preservation; clarify load-failure comment

Addresses PR review feedback:
- Add native unit tests (test_admin_radio) asserting handleSetConfig preserves the
  existing identity keypair when a security SET omits the private key, and applies a
  full supplied keypair (key import). Guards against reintroduced NodeNum/keypair
  regeneration. AdminModuleTestShim (now a friend) defers saves so the lightweight
  harness doesn't saveToDisk an uninitialized node database.
- Clarify the non-DECODE_FAILED config-load comment: OTHER_FAILURE / NO_FILESYSTEM
  cover an absent or unopenable file, not just first boot.

* beacon: encrypt on the beacon channel PSK; fix split note

When broadcast_on_channel overrides the primary channel's name/PSK, the
beacon was encrypted with the PRIMARY PSK: perhapsEncode keys encryption
off the primary slot, but the radio-thread channel switch happens only
after encryption. sendBeaconPacket() now installs the beacon channel into
the primary slot for the synchronous duration of send() (cooperative
threading => no interleaving) so encryption/hash use the beacon channel,
then restores it. A shared beaconChannelSettings() helper builds the
channel for both the encrypt-time swap and the RF-time swap so the
key+hash cannot drift.

Also: correct the legacy-split comments (both packets go out on the same
beacon radio settings, not the normal config) and merge the two
consecutive `if (hasText)` blocks in the listener (cppcheck
duplicateCondition).

Tests: add channelPskOverride_swapsBeaconChannelAndRestores and
noChannelOverride_doesNotSwapPrimary; MockRouter snapshots the primary
channel at send() time.

process exit, aborting the coverage run (surfaced by pio as [ERRORED] /
SIGHUP even though all 40 assertions passed).

Drain the phone queue in tearDown (getForPhone()/releaseToPool) so the
packets return to packetPool. Suite is now GREEN with no sanitizer abort.

* legacy hop override for zero-hoppers

* ever more beacons

* beacon: comment out broadcast_send_as_node pending further review

Functionality preserved in comments with full signing/has_bitfield notes
for when it is re-enabled. Proto tag 3 retained on the wire.

* test/beacon: fix fromIsCustomNodeWhenSet now that send-as-node is disabled

broadcast_send_as_node is commented out; from is always the local node.
Update the test assertion and doc comment to match current behaviour.

* flags for beacons

* beacon: do more with less — slot-index targets + validation

Multi-target beacons embedded a full ChannelSettings in every BroadcastTarget,
blowing ModuleConfig past the 512-byte BLE FromRadio budget so the firmware would
not compile. Targets now reference an existing channel-table slot by channel_index
and the broadcaster resolves it via channels.getByIndex() at TX time. Net effect:
the same multi-target capability for a fraction of the bytes —
FromRadio 609 -> 510 B, MeshBeaconConfig 596 -> 324 B, AdminMessage 615 -> 511 B.

- proto: BroadcastTarget.channel (embedded) -> channel_index (uint32 ref); regen all
  generated headers (size constants propagate to admin/localonly/deviceonly/mesh).
- broadcaster: resolve channel_index from the channel table; an out-of-range or blank
  slot falls back to the default channel for the target preset rather than borrowing
  the primary's name/PSK.
- AdminModule: validate broadcast_targets entries on write (region/preset sanitised
  like the single-target fields; channel_index range-checked).
- userPrefs: TARGET_<n>_CHANNEL_{NAME,NUM,PSK} collapse to a single CHANNEL_INDEX.
- docs: two-step (set_channel -> set_module_config) multi-target setup, inline-vs-
  reference distinction, and single-/multi-target are equal (not "legacy") options.
- tests: target validation + channel-index resolution incl. blank-slot fallback
  (47/47 green on `./bin/run-tests.sh -e native -f test_mesh_beacon`).

* throttling after reboot

* address copilot review

* simplify

* fix(beacon): use 0x%08x for node/packet IDs in logs; register test suite

The %#08lx log specifiers passed uint32_t (NodeNum/PacketId) to a %lx
length modifier — undefined behaviour on 64-bit (native test) targets and
non-standard width. Switch to the project-standard 0x%08x. Also bump
test/native-suite-count to 25 for the added test_mesh_beacon suite.

clod helped too

* copilot & clarity
clod helped too

* refactor(beacon): use auto for the sanitized config copy

clod helped too

* fix(beacon): guard empty-payload sends; gate has_mesh_beacon on build flag; document ISR_TX pre-switch

Clive BlackledgeandBen Meadors 98fa4a67db [feature] Free a little memory used by bluetooth if wifi is enabled or bluetooth is disabled (#10398)
* esp32: release BTDM heap when Bluetooth inactive

Release ESP-IDF BTDM memory after config load when Bluetooth is disabled or WiFi is enabled, recovering heap on ESP32 targets where BLE won’t be used for this boot.

* Address BT memory release review comments

TomandClaude Sonnet 4.6 c51c01607d Traffic Management module: dedup, rate limiting, role-aware policing (#10706)
Adds the Traffic Management module (TMM) plus the NodeDB/warm-store and
next-hop foundations it builds on:

- Unified per-node cache (flat array, 8-bit relative ticks) shared by all
  features; role-aware throttles for tracker / lost-and-found.
- Position deduplication: drop unchanged position rebroadcasts within a
  configurable interval; precision driven off the channel ceiling (clamped to
  the public-key max on well-known channels). Enabled by default at 11h.
- Per-node rate limiting and unknown-packet filtering (config-driven; a
  non-zero companion field enables each feature -- no bool toggles).
- NodeInfo direct response from cache with role-based hop clamps.
- Persistent next-hop overflow store: confirmed hops have no TTL, are seeded
  from NodeInfoLite at boot, and survive hot-store eviction.
- Three-tier sender-role resolution (hot NodeInfoLite -> warm store -> TMM
  cache). Role is cached write-time (seeded on first track, refreshed from
  NodeInfo), pins its cache entry like a next-hop hint, and is evicted last.
- Warm store caches device role + protected category across reboot/eviction.
- PositionModule stationary floor for tracker / lost-and-found.
- PSRAM gating for warm/satellite/TMM cache sizes; STM32WL excluded.

Protobufs: TrafficManagementConfig trimmed to the five uint32 fields actually
used; submodule repointed to protobufs develop.
