TomandBen Meadors 20f7ab1be9 Relay a PKI unicast with a known party in LOCAL_ONLY and KNOWN_ONLY (#11898)
* fix(router): relay a PKI unicast with a known party in LOCAL_ONLY and KNOWN_ONLY

A frame the relay cannot decrypt takes the OPAQUE_RELAY_ONLY path in
Router::perhapsHandleReceived() and returns before handleReceived(), so it never
reaches a module. The rebroadcast_mode rule for opaque traffic is therefore the
IS_ONE_OF list in relayOpaquePacket(), and LOCAL_ONLY and KNOWN_ONLY were not on
it: a node in either mode dropped every opaque frame, including a PKI unicast
with a party it knows. The gate in RoutingModule::handleReceivedProtobuf() that
used to allow exactly that is unreachable for these packets and no longer
decides anything.

Add both modes to the list, with the identity rule the unreachable gate carried:
a PKI-shaped unicast (channel 0, not broadcast) with `from` or `to` known to us.
An unreadable broadcast and a unicast between two strangers stay dropped in
these modes, which is what the proto documents - they ignore foreign meshes.

This is not only direct messages. Remote administration and key verification are
PKI unicasts too, and a KNOWN_ONLY relay was black-holing those between two
other nodes just the same.

CORE_PORTNUMS_ONLY reached this list the same way in #11843; this is the
remaining pair.

* test(rebroadcast_mode): pin the relay decision per mode, in both directions

What this node carries for other nodes, per DeviceConfig.rebroadcast_mode, for
packets it can read and packets it cannot. The harness pushes a real PKI frame
through Router::perhapsHandleReceived() and counts what reaches the radio.

Both directions are load-bearing, and each is guarded by cases the other leaves
green. Measured by rebuilding the firmware three ways:

  - as shipped: 9/9 pass.
  - with the two modes taken back out of relayOpaquePacket(): the known-party
    and remote-admin cases fail, the stranger and foreign-mesh cases still pass.
  - with the modes listed but the identity qualifier deleted: the stranger and
    foreign-mesh cases fail, the known-party cases still pass.

So a revert and an over-broadening each fail their own tests, and neither can be
satisfied by breaking the other.

The suite and its harness come from the opaque-packet-handling branch and
compile against develop unmodified. Two assertions were dropped because they
pin behaviour this branch does not add: delivery of unreadable frames to the
phone, and a queued copy of our own suppressing the originator's repeat, which
needs relayOpaquePacket() to consult the TX queue.

* fix(test): guard the harness include, drop a comment its test outlived

Two review findings on the imported suite.

The harness builds real PKI frames through CryptoEngine entry points a
MESHTASTIC_EXCLUDE_PKI build does not declare, but it was included above the
guard, so the empty-suite branch that exists for those builds could not compile.
Move the include inside the guard and pull the base includes the stub branch
needs above it.

The phone-delivery case was dropped when the suite came across - this branch
does not deliver unreadable frames to the phone - but its comment stayed behind
and now described the test below it, which is about the signature policy.

* test(rebroadcast_mode): make the from-known and channel-0 operands load-bearing

The qualifier has three operands, and the suite only exercised one of them.

Every existing case that a known party carries has a known DESTINATION: the
remote-admin case marks both parties, the known-destination case marks the
target. Rewriting the identity test to consult p->to alone passed all nine. And
the only non-PKI-shaped frame in the suite was a broadcast, which
!isBroadcast(p->to) rejects before p->channel is ever read, so deleting the
channel gate passed all nine too.

Add the two cases that close it: a known SOURCE with a destination we have never
heard of, which must relay in both modes, and a known party on a channel hash we
do not hold, which must not - that is someone else's channel traffic, addressed,
not PKI.

Measured both ways. With the from operand and the channel gate removed from
relayOpaquePacket(), the two new cases fail and the other nine pass; with the
shipping code, 11/11.

Raised by CodeRabbit on #11898.

Tom ee76117835 fix(router): relay opaque packets in CORE_PORTNUMS_ONLY (#11844)
* fix(router): relay opaque packets per rebroadcast_mode, not only in ALL

d6b12ea3f (#10967) moved undecryptable packets onto relayOpaquePacket(), which
relays only in ALL and ALL_SKIP_DECODING. A PKI unicast between two other
nodes - remote admin, a DM, key verification - is opaque to a relay, so a
router in CORE_PORTNUMS_ONLY (the ROUTER role default) stopped carrying any
of it, and KNOWN_ONLY / LOCAL_ONLY lost the rule 6eabbaf43 added in 2024 that
relays a PKI-shaped unicast with one known party. The old rule was still in
RoutingModule::handleReceivedProtobuf, unreachable: encrypted packets no
longer reach modules.

opaqueRelayAllowedByMode() gives each mode an explicit opaque rule:
ALL / ALL_SKIP_DECODING / CORE_PORTNUMS_ONLY relay (the port list cannot apply
to a packet with no readable port); KNOWN_ONLY / LOCAL_ONLY relay a channel-0
unicast whose sender or destination has a User in NodeDB; NONE relays nothing.
The dead RoutingModule block is removed; its licensed-party check stays for
decoded packets. Nothing here reads packet_signature_policy.

* fix(router): NAK, phone delivery and MQTT uplink for packets we cannot read

Before #10967 an undecryptable packet addressed to us reached RoutingModule,
which handed it to the phone and, via ReliableRouter::sniffReceived, answered
a want_ack unicast from an unknown sender with PKI_UNKNOWN_PUBKEY - the NAK
that makes the sender transmit its NodeInfo so its retry decrypts. A PKI DM
between two other nodes was uplinked to MQTT as ciphertext when encrypted
uplink was on. All three stopped: the gate REJECTs a to-us decode failure
before any module runs, and the pki_encrypted marking in dispatchReceived is
unreachable for opaque ingress.

passesRoutingAuthGate() now treats every DECODE_FAILURE not from us as opaque
(isFromUs stays REJECT, #11544). The opaque branch calls handleOpaqueForUs(),
which NAKs a want_ack unicast to us (PKI_UNKNOWN_PUBKEY when we hold no key
for the sender, NO_CHANNEL otherwise) and queues a frame we had no way to
read - PKI without the sender's key, or a channel hash matching nothing we
hold - straight to the phone via sendToPhone(), bypassing handleFromRadio()
so an unverified sender never touches NodeDB. A matched-and-failed frame
(bad key, tampering, junk) is NAKed but not delivered. uplinkOpaqueUnicast()
restores the MQTT path for channel-0 unicasts not to or from us, gated on
mqtt.enabled and mqtt.encryption_enabled; the dead marking is removed.

* test(packet_signing): pin what a relay does with traffic it cannot read

Group R builds genuine PKI-encrypted packets between two generated
identities and runs them through ingress under every rebroadcast_mode:

  R1  remote admin between two known nodes relays in every mode but NONE
  R2  between strangers: KNOWN_ONLY / LOCAL_ONLY decline, the rest relay
  R3  one known party satisfies KNOWN_ONLY / LOCAL_ONLY
  R4  an unknown-channel broadcast relays in ALL / ALL_SKIP / CORE only
  R5  undecryptable DM to us: one PKI_UNKNOWN_PUBKEY NAK, phone gets the
      frame, nothing relayed, sender not added to NodeDB - in every mode
  R6  the same frame claiming to be from us gets no reaction
  R7  sender key held but wrong: NAK NO_CHANNEL, no phone delivery
  R8  opaque PKI unicast is uplinked only with encrypted MQTT uplink
  R9  unknown-channel broadcast reaches the phone without touching NodeDB
  R10 the relay decision is identical under all three signature policies

C6 no longer lists CORE_PORTNUMS_ONLY as a mode that suppresses opaque relay
and expects the phone to see an unreadable frame; the RoutingModule mock
records the NAK reason.

* test(rebroadcast_mode): give the relay policy its own suite, sharing the ingress harness

test/support/AuthPipelineHarness.h now holds the mock NodeDB, the counting radio /
router / routing-module / module / MQTT, the packet builders (decoded, channel-
encrypted, PKI between two generated identities) and the per-process / per-test
lifecycle that test_packet_signing kept locally.

test_rebroadcast_mode pins what this node carries for others, per
DeviceConfig.rebroadcast_mode: remote admin between two known nodes relays in
every mode but NONE; strangers are declined by KNOWN_ONLY / LOCAL_ONLY and
carried elsewhere; one known party suffices; an unknown-channel broadcast relays
in ALL / ALL_SKIP / CORE only; a licensed node never relays ciphertext and
relays plaintext unless a party is known unlicensed; hop_limit 0, id 0, a
foreign next_hop and CLIENT_MUTE each stop a relay; the signature policy
changes none of it. Registered in state-manifest.tsv and the routing shard.

test_packet_signing keeps what follows from the auth gate's verdict: C9-C11 now
carry want_ack and hops so their "nothing happens" assertions are no longer
vacuous (junk on a held channel relays but never reaches the phone; a legacy
DM and a malformed PKI plaintext to us are NAKed NO_CHANNEL once and nothing
else), and C18-C22 cover the to-us NAK / phone / MQTT outcomes. Comments on the
src side trimmed to the two-line rule.

* fix(router): classify an opaque frame from the decode attempt, not the header

handleOpaqueForUs() re-derived "unreadable" from the wire header and NodeDB,
which disagreed with what perhapsDecode() had just found: a hash-0 broadcast
from a sender whose key we hold read as readable although PKI never applies to
a broadcast, and a pending-key decrypt rejected as malformed read as unreadable
because no stored key existed. Both changed the NAK reason and whether
ciphertext reached the phone.

passesRoutingAuthGate() now hands the attempt's DecodeState out and the handler
takes unreadable = (state == DECODE_OPAQUE). For that to be precise,
perhapsDecode() sets pkiAttempted only when a sender, pending or admin key was
actually tried, and the KNOWN_ONLY short-circuit - which declines before any
attempt - reports OPAQUE for a PKI-shaped unicast to us or an unheld hash and
FAILURE for a held channel. isUnreadableToUs() is gone; Channels::hasHash()
replaces its loop.

* test(support): free the harness AirTime and NodeStatus before restoring the originals

pipelineHarnessDestroy() restored the saved pointers and orphaned the two
objects it had installed. LeakSanitizer reported the NodeStatus as a 160-byte
direct leak and errored test_packet_signing and test_rebroadcast_mode at exit
in the coverage shards while every case passed.

* fix(router): a failed admin-key fallback does not count as a decrypt attempt

Every configured admin key set pkiAttempted, so on a node with any admin key
an unknown sender's DM read as DECODE_FAILURE: NO_CHANNEL instead of
PKI_UNKNOWN_PUBKEY, and withheld from the phone, so the sender never learned to
send its NodeInfo. An admin key that fails says nothing about the sender; only
the sender's own (or pending) key counts. A successful-but-malformed admin
decrypt already returns DECODE_FAILURE directly.

* test(packet_signing): pin decode provenance for admin keys, forged from-us frames, hash-0 broadcasts and KNOWN_ONLY strangers

C18 configures an unrelated admin key so the fallback runs and fails. C19
installs our identity so the forged frame is a real decrypt attempt and asserts
the gate's REJECT before the side effects. C23: a hash-0 broadcast from a keyed
sender on a channel we do not hold is unreadable and reaches the phone. C24:
KNOWN_ONLY declines a stranger on a held channel as matched, so the phone never
sees it, while the same stranger on an unheld channel is unreadable.

* test(support): restore the caller's DH key, model the TX queue and ACK/NAK log, clear per-process state between tests

The ingress harness builds its router, radio, routing module and crypto engine
once per process, so anything they carry decides the next test's outcome. Three
of those carried surfaces were already deciding one.

makePkiUnicastBetween() ended by installing a fresh random DH key, so a caller
that set its own key before building a frame silently lost it. C19 did exactly
that: its REJECT assertion passed because the decrypt failed on a key mismatch,
not because the from-us arm rejected the forgery, and would have stayed green
with that arm deleted. CryptoEngine::private_key is public under
PIO_UNIT_TESTING, so the helper now saves the engine's key and puts it back;
the trap is closed for every caller rather than worked around in one. C19 also
builds the frame before installing our identity and gains a control assertion:
without our key in NodeDB the same frame is OPAQUE_RELAY_ONLY, which is what
makes the REJECT attributable.

The opaque dedup ring survived a whole suite unreset. That was tolerable while
it only gated relay; it is about to gate the NAK, phone delivery and MQTT
uplink too, where a stale (from,id) would silently zero a later test's
expectations instead of failing it. Cleared per test, along with the DH key,
any pending handshake key, and the admin-key fallback budget that C18 drains
six tokens from. resetAdminKeyFallbackBudget() is defined under
!MESHTASTIC_EXCLUDE_PKI but declared unguarded, so the call site is guarded.

installOurIdentity() now marks HAS_USER on our own node, as NodeDB does on a
device. The rebroadcast_mode predicates read that bit, and markOurselvesLicensed()
keeps owner.is_licensed and our NodeDB record in agreement for the same reason:
getLicenseStatus(us) must say Licensed, not NotLicensed.

The radio and routing-module mocks become models rather than counters, since
every suite including this header gets them. The radio holds a real TX queue
that findInTxQueue() consults and that cancelSending()/removePendingTXPacket()
take entries out of, and it records each frame it was handed so a test can
assert a hop limit or relay_node instead of a call count. The routing module
keeps every ACK/NAK with its destination, channel and hop limit, so a second
NAK can be pinned without losing the first; its reset() replaces the six sites
that zeroed ackCalls by hand, which would otherwise desync the log from the
counter. Phone-queue draining moves into the harness for the suites that both
need it.

* refactor(router): the opaque path lives in Router, not NextHopRouter

A pure move. Nothing about handling a frame we cannot read is next-hop
specific: relayOpaquePacket() reads iface, isToUs/isFromUs, the device role,
owner.is_licensed, the last byte of our node number and the packet's own
header, then calls Router::send(). The one thing that held it in the subclass
was the (from,id) dedup ring, and that landed in NextHopRouter next to the
pending and route-health tables by proximity rather than dependency - its
whole purpose is to stay isolated from routing state, which argues for sitting
beside PacketHistory instead.

So the ring, opaqueWasSeenRecently(), relayOpaquePacket() and the
rebroadcast_mode predicate (now Router::opaqueAllowedByMode) move down, and
relayOpaquePacket() stops being virtual: there is one router chain, nothing
else overrode it, and the base implementation returned false to no one. The
alternative was a second virtual to reach the same array from the same caller,
which is what the dedup work that follows would otherwise have needed.

isRebroadcaster() comes along because relayOpaquePacket() needs it and it reads
only config.device - no FloodingRouter state - so it was already misplaced.
capEventRelayHops() moves too, and is now declared for NextHopRouter's own
rebroadcast path rather than being file-static.

* fix(router): apply the packet's own rules to every consumer of an opaque frame

Five rules that pre-#10967 applied to a packet we could not read were left
applying to the relay alone. This puts them back on all four consumers - relay,
NAK, phone, MQTT - which is one change of shape, so it lands as one commit
rather than five: the branch head now computes what is true of the frame once
and every consumer below reads the same answer.

Duplicate suppression. The only dedup sat inside relayOpaquePacket(), behind
its isToUs() early return, so it never saw a frame addressed to us. Three
neighbours rebroadcasting a stranger's want_ack DM to us cost three
PKI_UNKNOWN_PUBKEY NAKs on the air, three encrypted frames queued for the
phone, and at a gateway three publishes of every opaque PKI DM between other
nodes. Before these packets stopped going through PacketHistory,
shouldFilterReceived() ran first and made each of those once per (from,id).
The originator's own retransmission keeps its exemption, and gains the two
rules the decoded path already applies to a repeat: do not queue a second copy
while the first is still in the TX queue, and answer again at hop 0, since only
a direct neighbour ever sees hop_start == hop_limit.

rebroadcast_mode. LOCAL_ONLY and KNOWN_ONLY say the node ignores what it cannot
decrypt; the deleted RoutingModule branch gated phone delivery as well as
relay, and only the relay half was carried over, so a stranger's unknown-channel
ciphertext reached the phone in every mode. The phone now follows the same
predicate. NONE still delivers: it means do not relay, not do not listen.

Licence. A licensed station transmits in the clear and may not answer, or hand
on, traffic to or from a node it knows to be unlicensed - the rule RoutingModule
applies to decoded packets, which the opaque path never got.

NAK reason. PKI_UNKNOWN_PUBKEY claimed a missing key even for a channel-0 frame
too short to have carried PKI overhead. Such a frame was never a candidate, so
the reason is NO_CHANNEL, matching the size test perhapsDecode uses.

Uplink. uplinkOpaqueUnicast() read the header only, so a channel-0 unicast that
matched a held hash-0 channel and failed its AEAD was published to the PKI
topic as ciphertext we never tried to read. It now takes the gate's verdict.

One consequence worth stating: the dedup ring records frames the relay gate
used to reject before reaching it - to us, from us, hop-exhausted, mode-blocked,
and everything on a licensed node - so its 32 slots serve four consumers on
nodes that previously never touched it.

Two clean-ups ride along because the same rules move: ReliableRouter's
sniffReceived() loses its own undecryptable-NAK arms, which radio ingress has
not been able to reach since the auth gate started answering those frames
before handleReceived() (deliverLocal, the only other caller, is always
decoded), and test_rebroadcast_mode stops declaring a warm.dat write it never
makes - no case in it reads a signer back from the warm store.

* test(rebroadcast_mode): declare the warm-store write again

The suite stopped writing warm.dat only until this branch gave it a test that
installs an identity of our own, which puts a key through the warm store. The
declaration was removed on the evidence of a run that predated that test, in
the same commit that added it; the harness caught the undeclared write.

* fix(router): put back the undecodable-NAK arms in ReliableRouter::sniffReceived

Deleted as dead code, and they are not. Radio ingress genuinely cannot reach
them any more - the auth gate answers an unreadable frame in
handleOpaqueForUs() and returns before handleReceived(), and deliverLocal(),
the only other caller, is always decoded - but sniffReceived() has a contract
of its own that test_reliable_ack_matrix drives directly, and a local or
SimRadio caller still arrives with an encrypted packet. CI caught it in the
misc-4 shard.

Restored verbatim, with the reachability noted where the next reader will look
rather than in a commit message nobody greps.

* fix(router): classify a PKI-shaped unicast from key material alone

Addresses the review on #11844.

A channel we hold whose hash is 0 matched every PKI DM on the mesh and
failed every one, and that failure was read as "we tried". One unlucky
1-in-256 channel hash therefore withheld every PKI DM from the phone and
the broker, answered NO_CHANNEL where the sender needs PKI_UNKNOWN_PUBKEY
to recover, and classified our own overheard DMs as a forgery so the
implicit "Delivered to mesh" ACK never fired. Hash 0 on a unicast is the
PKI sentinel, so isPkiShapedUnicast() now decides it in one place, used by
the KNOWN_ONLY short-circuit, the decode provenance and the NAK reason.
The isToUs asymmetry in the short-circuit is gone with it.

Also from the review:

- id 0 cannot be deduped by the (from,id) ring, so an undecryptable
  want_ack DM carrying it drew a NAK and a phone frame on every copy
  heard. Every consumer now declines it, as relay already did; a NAK for
  request_id 0 is unmatchable at the sender anyway.
- The ring records only frames some consumer can act on. Our own
  overheard rebroadcasts and unicasts that can neither be relayed nor
  uplinked were evicting live entries, spending the anti-amplification
  bound #11522 added it for.
- The MQTT uplink applies the licensed-station rule, and deliberately not
  rebroadcast_mode: that setting governs what goes back on the air, and
  MQTT has its own switches for what leaves over IP, which is where the
  pre-#10967 uplink sat.
- gateState is initialised rather than relying on the gate's first
  statement.

Comments on the opaque path trimmed to the two-line rule; the reasoning
lives in the tests, which are exempt.

* ci(size-budget): raise the rak4631 flash budget to 748000

The opaque-relay restore lands at 746,080 bytes on rak4631, 80 bytes over
the previous 746,000 limit. Image ends at 0xDC260, 55 KB clear of the warm
region.

* fix(router): keep #10967's removal of the undecodable-frame NAK

The PKI_UNKNOWN_PUBKEY / NO_CHANNEL NAK for a frame we cannot read is not
restored. Every input to that decision - to, from, id, want_ack, hop_start,
hop_limit - is unauthenticated cleartext, so the NAK is a reflector: one
frame in from a node with no key material, one flooded reply out to
whichever `from` it names, with a hop budget the sender chooses. #10967
removed it as an ACK side effect on purpose; the security review of this PR
shows why, and the relay regression it fixes does not need it.

handleOpaqueForUs() now only delivers to the phone. The originator-retx
re-NAK and its `repeat` plumbing go with the NAK. A to-us DECODE_FAILURE is
REJECT again at the gate, as #10967 had it: nothing on the opaque path acts
on a frame we matched and failed on. ReliableRouter::sniffReceived() is back
to develop byte for byte; its undecodable arms are reachable by local and
SimRadio callers only and stay as they are.

A PKI DM to a node that does not hold the sender's key fails silently, as on
develop; the receiving phone still sees the frame. The sender-side recovery
this NAK used to trigger is the follow-on's problem to solve without a
header-driven reply.

Tests: C10, C11, C18, C20, C26, C27, C29, C31 assert no NAK; C28 (the NAK's
hop budget) is deleted; the matched-failure helper drops its want_ack arm.

* fix(router): do not re-decode a frame the gate already classified; scope capEventRelayHops

handleOpaqueForUs() hands the phone a copy the auth gate has already run
perhapsDecode() on. MeshService::sendToPhone() ran it again, and for a
PKI-shaped DM from a sender whose key we lack that second pass re-enters the
admin-key fallback and spends a second token from a budget the code documents
as global and attacker-facing: the sustained rate halved from 4/s to 2/s on
any node with an admin key configured. sendToPhone() takes an
alreadyClassified flag and skips the decode; nothing else calls it that way.
Nodes with no admin key configured were never affected, since
adminKeyFallbackAllowed() returns before touching the bucket.

test_C34 freezes the clock, configures an unrelated admin key, and pins one
token spent per unreadable frame delivered to the phone.
adminKeyFallbackTokensRemaining() is a PIO_UNIT_TESTING accessor beside
resetAdminKeyFallbackBudget().

ReliableRouter::sniffReceived()'s PKI_UNKNOWN_PUBKEY arm now requires the
frame to be long enough to have carried the PKI overhead, the same shape test
Router's opaque classification applies; a shorter channel-0 frame was never a
PKI candidate, so no key was missing and it gets NO_CHANNEL. Reachable by
local and SimRadio callers; pinned in test_reliable_ack_matrix.

capEventRelayHops() moved out of NextHopRouter.cpp as a file-static and
became a free function at global scope. Both callers are Router subclasses,
so it is now a static member of Router next to isRebroadcaster().

* fix(router): size the opaque dedup ring like PACKETHISTORY_MAX

Every ROUTER relays opaque frames now, not just nodes set to ALL, so the
churn through this ring is what bounds a duplicate storm on the backbone.
32 untimed slots shared by three consumers is thin for that; 128 on every
target but STM32WL, which keeps 32 alongside its 20-entry PacketHistory.
8 B per slot in .bss: +768 B, no flash.

* revert(router): return the branch to develop

* fix(router): relay opaque packets in CORE_PORTNUMS_ONLY

A packet a relay cannot decrypt - a PKI unicast between two other nodes, an
unknown-channel broadcast - is relayed only from its header, and only in the
rebroadcast modes relayOpaquePacket() lists. CORE_PORTNUMS_ONLY was not among
them, so a node in that mode, which is the ROUTER role default, dropped every
such packet. The portnum filter that mode exists for cannot be applied to a
payload the relay cannot read; add the mode to the list.

Fixes #11843.

* test(packet_signing): CORE_PORTNUMS_ONLY carries an opaque frame

C6 listed CORE_PORTNUMS_ONLY among the modes that must suppress an opaque
relay, pinning the behaviour #11843 reports. It now asserts the frame is
relayed in that mode, with the same no-side-effect checks as the ALL case, and
keeps LOCAL_ONLY and NONE as the suppressing modes.

ee15508494 time: arm the remaining 0-means-unset stamps through the helpers (#11830)
* 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.

* 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.

* 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.

* time: arm the remaining 0-means-unset stamps through the helpers

The follow-up sweep to the sixteen fields the previous commits covered. A field
here uses 0 to mean "unset" - some read spells `if (f)`, `f != 0`, `f == 0 ||` or
`f > 0`, or a site disarms it with `f = 0` - but it was armed from a raw clock read,
so once per ~49.7-day wrap it stores the value its own readers treat as never-set.
34 fields, 58 arm sites.

The rule could not have found most of them first. It treated `field = <variable>`
as inheriting whatever that variable did, which made the commonest shape in the tree
invisible: one `now = millis()` at the top of a runOnce(), then several
`xStartTime = now` below it. Listing those names would have bought no protection at
all, so the scanner now tracks a local assigned from a clock and treats a write from
it as the raw arm it is. One hop, one function, name-based, and it forgets a local
reassigned from anything else; taint is dropped at each function boundary. Twelve
fixtures pin it, including the negative cases - no leak across functions, `now` does
not match `nowMs`, and neither `==` nor `+=` records anything.

That pass immediately found a site the previous commits missed: setTransmitDelay()
recomputes p->tx_after from a tainted `now`, two lines under the `if (p->tx_after)`
read that takes 0 as "no delay wanted".

Three of the fields are worth naming because the consequence is not cosmetic:

  * UpDownInterruptBase press/up/downStartTime - xDetected is only cleared INSIDE
    the block guarded by `xDetected && xStartTime > 0`, so a stored 0 makes both the
    entry and the exit condition unreachable and that button is dead for the rest of
    the boot, not for one tick.
  * PhoneAPI lastContactMsec - ServerAPI reads `lastContactMsec > 0` before the TCP
    idle close, and the field stays 0 until the next inbound packet, so a client that
    never speaks again leaks the socket for the life of the connection.
  * EInkDisplay lastDrawMsec - `if (lastDrawMsec)` gates every plain display() call
    on a keyframe having been shown, so a stored 0 stops the screen updating until
    something calls Screen::forceDisplay() again.

TransmitHistory needed more than its arm sites. getLastSentToMeshMillis() returns 0
to mean "module has never sent", and besides the two stores, both reconstruction
helpers end in `millis() - msAgo`, which can produce a 0 of their own. All three
computed returns are guarded; the deliberate `return 0;` sentinels are untouched.

Judged and deliberately not changed:

  * nRF54L15 connect_time_ms is armed from k_uptime_get_32(), not millis(). It is
    guarded with skipZero() but keeps its own clock - swapping in Time::getMillis()
    would have it compared against a k_uptime now at the watchdog read. The rule now
    recognises that clock too, so listing the field is not an empty gesture.
  * RotaryEncoderInterruptBase pressStartTime shares a name with the UpDown field and
    has a different contract: no read here tests the stamp against 0, pressDetected
    is the only armed flag. Opted out at the write. Its lastPressLongEventTime
    sibling IS a `== 0` latch and is fixed.
  * PositionModule line 38 copies a value the enclosing `if (restored != 0)` has
    already proven non-zero. Opted out.
  * pmMeasureStarted, adminKeyFallbackRefillMs, the two autosave stamps and
    scrollStartDelay are lazy initialisations whose wrap behaviour costs at most one
    interval and drops nothing. Left alone, and not listed.

47 lint fixtures green, the rule silent across src/, full native suite 1421/1421.

* time: dodge the wrap at the clock read, not only at the store

Review on #11830 made a point that was right and that this branch had wrong.
Applying skipZero() at the STORE while a reader measures elapsed time against a
raw clock splits the two sides apart for one tick per ~49.7-day wrap: the stamp
becomes 1 while `now` is still 0, so `now - stamp` is UINT32_MAX and a brand new
stamp reads as about 49.7 days old. Every elapsed-since guard then fires when it
must not. Concretely, UpDownInterruptBase computed `now - pressStartTime` and
emitted a long press for a fresh press, and TraceRouteModule read
`now - lastTraceRouteTime < cooldownMs` as false and bypassed its cooldown.

So the dodge moves to the read. Time::stampMillis() is getMillis() with the one 0
tick called 1; a site that both stores a stamp and measures against stamps reads
the clock once through it and stores that value directly. Nine files, and the 1 ms
skew is the same one skipZero() already documents.

Where the clock arrives as a PARAMETER the store keeps its own skipZero() as well,
because the function cannot assume the caller dodged anything. Removing that was a
real regression and test_nexthop_routing caught it: noteRouteLearned() and
noteRouteSuccess() are called with a literal 0 by
test_health_learn_never_stores_zero_sentinel and
test_health_success_never_stores_zero_sentinel, which assert the store normalises
it - 0 is the empty-slot marker getOrAllocRouteHealth() evicts on. The two guards
compose without shifting twice, since skipZero() of a non-zero value is itself.
trySmartBroadcast() and directResponseAllowed() have the same parameter shape and
keep their store-side guard for the same reason. Only stores fed by a stampMillis()
local in the same function are bare.

EInkParallelDisplay was missed the first time: the third class in the family, still
storing skipZero(getMillis()) while rate-limiting against a raw millis() local.
Normalised like its siblings.

The lint rule gained three false positives with the class-scope tracking, all of
them shapes that are not class bodies at all:

  template <class T> void f(T x) { uint32_t lastSort = millis(); }
  class Foo { void tick() { uint32_t lastSort = millis(); } };
  void g(struct Bar *b) { uint32_t lastSort = millis(); }

Two causes. pending_class matched class/struct anywhere on the line, so a template
parameter list and an elaborated type in a parameter list both marked the following
FUNCTION body as class scope; it is anchored to the start of the line now. And
update_scope() runs at the end of a line, so a body opened earlier on the same line
had not been counted when the statement was judged; is_declaration() now also
counts unmatched braces earlier in the statement. The rule is blocking and
`template <class T>` is ordinary C++, so these would have reddened files nobody
touched.

note_taint() also never received the per-write `;` cut the judging path was given
earlier in review, so on a line holding two statements it learned taint from the
neighbour. Same cut applied.

Five tests in test_uptime_clock pin the contract, including one that asserts the
old store-only shape really does produce UINT32_MAX, and one that pins the 1 ms
skew at 399 rather than 400 so nobody "corrects" it back into a raw read. Lint
fixtures 53 -> 65. Full native suite 1426/1426, rule silent across src/.

Known residual, deliberately not changed: a store that dodges zero while its reader
measures through a Throttle:: helper still splits for that one tick, because those
helpers read the clock internally and raw. About eight sites tree-wide, including
PositionModule trySmartBroadcast and the lastContactMsec TCP idle check. Closing it
means making Throttle read through the dodge, which was proposed on #11692 and
declined there pending a caller audit, so fixing one site here would only make the
tree inconsistent. The direction is also the same one the un-dodged code already
took: a fresh stamp reads as old, and the guards involved were already passing on a
0 stamp.

* lint: a dodged value is safe to copy, not to do arithmetic on

Two more review findings on the rule, both real, both false negatives.

Arithmetic on an already-dodged value was excused. stampMillis() guarantees only
its own result, so `now + 5000` can carry a non-zero stamp straight back onto the
sentinel - 0xFFFFEC78 + 5000 is exactly 0. That sum is precisely what
Time::timerEndsAtMillis() exists to dodge, and the rule was waving it through
because a helper name appeared somewhere in the expression. Worse, a fixture
asserted that behaviour was correct, so the self-test was pinning the hole open.

A local holding a dodged value is now tracked separately from a tainted one: it may
be stored or copied straight through, but + or - applied at the OUTERMOST level is
reported and the message points at timerEndsAtMillis(). Depth-aware, so the operator
inside Time::skipZero(getMillis() - msAgo) is still fine, and so is the
`(d == 0) ? 0 : timerEndsAtMillis(d)` arming form, which has no top-level operator
at all. The wrong fixture is replaced by four: store-through, copy one more hop,
arithmetic on a dodged local, and arithmetic on a direct helper call.

A class body that opens and closes on one line was never recognised. The header
check rejected it because the line ends in a semicolon, which a one-liner body
always does, and even once armed the class brace counted as a function body and
excused the member. Both halves fixed: the header arms on the brace rather than on
the absence of a semicolon, and when the body opened on the statement being judged,
one unmatched brace is class scope while two is a method body inside it. Getting
that wrong first broke every multi-line class, because setting the per-statement
flag without also arming pending_class meant update_scope() never registered the
body - the three existing class fixtures caught it.

72 fixtures, green under bash 3.2, shellcheck clean, rule silent across src/.
No src/ or test/ file changes, so the native suite is untouched by this commit.

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.

* 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.

* 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.

3a7c499722 fix(mesh): dedup opaque relays to prevent an undecryptable-frame broadcast storm (#11522)
* NextHopRouter: dedup opaque relays to prevent a broadcast storm

Undecryptable ("opaque") frames are relayed by relayOpaquePacket(), which by
design never enters PacketHistory - so unauthenticated frames can't poison
next-hop learning or ACK matching (packet-authenticity policy, d6b12ea3f).
But PacketHistory admission was also the *only* deduplication on that path.
With none, a dense mesh re-relays every copy of every opaque frame and the
copy count multiplies at each hop into an unbounded broadcast storm; "let hop
exhaustion bound it" caps depth, not count.

Add a small, isolated (from,id) seen-set checked in relayOpaquePacket()
before rebroadcast: a second PacketHistory-style table (fixed 32-slot ring,
round-robin eviction) that only suppresses duplicate opaque rebroadcasts and
never feeds routing/ACK/next-hop, preserving the security property. Genuine
originator (re)transmissions (hop_start == hop_limit) are still relayed so
reliable opaque unicast propagates (mirrors FloodingRouter's isRepeated).

Observed on a mixed-channel mesh: one node relayed a single undecryptable
broadcast 23x (every overheard copy) with TX queues saturated, while
decodable traffic on the same node deduped normally.

fdb644e0b7 Fix millis() rollover in deadline, interval, and timestamp handling (#11291)
* Add native test coverage for the UptimeClock monotonic seam

src/UptimeClock.{h,cpp} shipped without a dedicated test suite. Port the six
tests from the monotonic-time branch (test/test_time), retargeted to the
renamed header.

The wrap test crosses 0xFFFFFFFF via advanceTestMillis() rather than a second
setTestMillis(): setTestMillis() sets clockSourceChanged, which makes
getMillis64() rebase its accumulator and swallow the wrap.

* NextHopRouter: fix 49.7-day millis() rollover in retransmission timing

Resolves the "FIXME, handle 51 day rolloever here!!!" in
NextHopRouter::doRetransmissions() by switching the retransmission-due
comparison from plain unsigned <= to a signed-difference cast.

The previous p.nextTxMsec <= now comparison silently breaks across the
~49.7 day millis() wraparound: pending retransmissions either stall
for the remainder of the wrap window, or all fire simultaneously at
the rollover boundary. Long-running router/infrastructure nodes do hit
this in practice.

The replacement (int32_t)(p.nextTxMsec - now) <= 0 is the standard
Arduino/embedded idiom for rollover-safe deadline checks and behaves
identically to the original for any non-wrap timing.

* Address Copilot review: use unsigned half-range for rollover-safe retransmit check

Review feedback from @Copilot on PR #10227: casting a uint32_t
subtraction to int32_t is implementation-defined in C++ when the
unsigned value exceeds INT32_MAX (even though it works on typical
two's-complement targets).

Switch to the fully well-defined unsigned half-range form:
  nextTxMsec is in the past-or-equal iff (now - nextTxMsec) has not
  wrapped past 2^31 ms. Future offsets < 2^31 ms wrap into the top
  half and read as 'not yet'.

Same semantics as the signed-cast version on every two's-complement
platform we care about, but portable to any conforming C++ impl.

* Use monotonic time for airtime windows

* Document monotonic airtime windows

* Fix test_packet_signing sentinel that #10227's rollover fix inverts

test_C3_invalid_repeated_packet_cannot_ack_or_change_retry_state parked a
pending packet at nextTxMsec = UINT32_MAX to mean "never retransmit", then
asserted that a rejected repeated packet leaves the retry state untouched.

NextHopRouter::doRetransmissions() now tests whether a retransmit is due with
an unsigned half-range compare, (uint32_t)(now - nextTxMsec) < 0x80000000u,
so that retransmission timing survives the ~49.7 day millis() wrap. Under it
now - 0xFFFFFFFF == now + 1, a small positive delta, so UINT32_MAX reads as
~1ms in the past: the retransmit fires and rewrites nextTxMsec, and the test
failed with "Expected 4294967295 Was 6247".

Use a representable future time instead. Production is unaffected either way -
nextTxMsec is only ever written as millis() + d, and UINT32_MAX came from the
test harness alone - so the sentinel is what needs to go, not the comparison.
Special-casing UINT32_MAX in the retransmit path would keep a value that reads
as "expired" under any wrap-correct compare.

The value is held in a local because millis() advances across
runPipelineIngress(), so recomputing it at the assertion would compare against
a different number.

Reported upstream on meshtastic/firmware#10227, whose branch predates this test.

* Make Throttle time-injectable and add hasElapsed()

Throttle backs ~94 call sites, which makes it the highest-leverage place in
the tree to put the clock seam: reading Time::getMillis() instead of millis()
in its three call sites turns all of them into time-injectable code at once,
without touching any of them. The 32-bit millis() wrap is not otherwise
reachable from a native test.

The read is behaviour-preserving - Time::getMillis() returns millis() unless a
test injects a clock - and the full native suite passes with it live.

Also add hasElapsed(), the complement of isWithinTimespanMs(), because 51 of
the 94 call sites are spelled !isWithinTimespanMs and read poorly. Its
boundary is inclusive (>=) since isWithinTimespanMs uses <; both are
documented. It deliberately does not treat lastExecutionMs == 0 as "never
run": call sites pair that test with the interval check themselves, and
absorbing a sentinel into the one helper every module depends on is exactly
the value-overloading hazard being removed elsewhere.

Migrating the existing !isWithinTimespanMs sites is cosmetic and deliberately
left out of this commit.

test/test_throttle/ covers window semantics, both boundaries, the complement
identity, execute()'s first-run and throttled paths, and - the point of the
exercise - a window opened before the wrap closing correctly after it,
including at the 24h interval that is the longest in the tree.

* Stop disarmed deadline sentinels reaching the comparison

Two deadline variables encoded "inactive" as a magic value that only reads as
"never" because the comparison against it is a naive millis() compare. Under
any rollover-correct comparison both invert to "expired ~49 days ago", so they
have to be untangled before those comparisons can be fixed.

Power::reboot() set rebootAtMsec = -1 on platforms with no reboot
implementation, intending "never fire". Every reader already treats 0 as the
disarm value - powerCommandsCheck() tests `if (rebootAtMsec && ...)`, and
AdminModule writes 0 to cancel - so -1 was both wrong and unnecessary. Use 0.
Left as UINT32_MAX it would reboot-loop the moment the comparison is corrected.

ExternalNotificationModule's nag window compared against nagCycleCutoff, which
holds UINT32_MAX once stopped and 1 at boot. isNagging is the real armed flag,
so test it first and short-circuit: a disarmed cutoff can no longer reach the
arithmetic, while an idle module still takes the same sleep path that the
boot-time value of 1 was relying on.

Note this fixes the sentinel only. The comparison itself is still a naive
`nagCycleCutoff < millis()` and remains on the list to convert.

* Fix millis() rollover in every deadline and interval comparison

Roughly 20 sites compared against millis() directly - `millis() > deadline`,
`deadline < millis()`, `last + interval < millis()`. All of them break for
about 24 days after the 32-bit millis() wrap: depending on which side of the
wrap each value sits, the action either stalls for weeks or fires immediately
and repeatedly. The longest affected interval is the 12 hour NTP renewal, a
~50x margin against the wrap, so none of these needed the range - only the
correct comparison.

Add Throttle::deadlinePassed(deadlineMs) for sites that store an absolute
deadline they cannot re-express as "interval since an event". It uses the same
unsigned half-range test as NextHopRouter::doRetransmissions() rather than
introducing a competing signed-cast idiom, and unlike the signed cast it is
defined for every input. Sites that do store an event use the existing
isWithinTimespanMs / hasElapsed. Nothing gained new state.

Because both helpers read Time::getMillis(), every converted site is now
reachable from a native test that drives the clock across the wrap; the
comparison itself is covered directly in test/test_throttle/.

Sentinel handling is the reason this could not be a mechanical rewrite. The
disarm convention is not uniform: 0 means "inactive" for rebootAtMsec,
shutdownAtMsec, alertBannerUntil, fixHoldEnds, suppressUntilMs and
touchResumeBlockUntilMs; 0 means "due now" for ntp_renew, which is forced to 0
at link-up; UINT32_MAX means "inactive" for nagCycleCutoff; and
alertBannerUntil == 0 in isOverlayBannerShowing() means "show indefinitely".
Every inactive marker is arithmetically far in the past, so a correct
comparison fires on it - each site tests its sentinel before the arithmetic,
and keeps the meaning it had.

Two sites carried a second bug found on the way:

BME680Sensor tested (stateUpdateCounter * STATE_SAVE_PERIOD) < millis(). With
a 6 hour period and a uint16_t counter that product overflows uint32_t after
about 198 saves, independently of the millis() wrap. It now measures the
interval since the last save.

EInkDynamicDisplay had `if (previousRunMs > millis()) return;` as a millis()
overflow guard, which skipped rate limiting entirely for the whole post-wrap
period - the bug it meant to prevent. Every check below it already goes
through Throttle, so the guard is removed rather than fixed.

MotionSensor's calibration countdown is converted to a signed delta rather
than deadlinePassed, because it needs the remaining magnitude and not a
boolean; that matches the already-correct check in the same file.

* Remove getMillis64() and use Throttle for the NodeInfo reply window

getMillis64() had exactly one caller and no callers in tests. It also carried
obligations that made it the wrong shape for this firmware: a wrap accumulator
in mutable statics, which is not ISR-safe, and which must be polled at least
once every ~49.7 days or it silently misses a wrap and returns a time ~49 days
short.

Its one caller only wanted to know whether a 12 hour suppression window had
elapsed - which Throttle answers correctly across the wrap without any
accumulator. NodeInfoModule now stores Time::getMillis() in lastNodeInfoSeen
and tests the window with Throttle::isWithinTimespanMs, so the map holds
milliseconds rather than seconds derived from a 64-bit read.

USERPREFS_NODEINFO_REPLY_SUPPRESS_SECS is user-overridable and now feeds a
multiply by 1000, so a static_assert rejects any value too large to express in
milliseconds instead of letting it wrap.

clockSourceChanged goes too. It existed solely to rebase getMillis64()'s
accumulator when a test swapped clock sources, and it made the wrap untestable
through the injection API: setTestMillis() set the flag, so a wrap crossed by
two setTestMillis() calls was swallowed. With the accumulator gone the flag has
nothing to rebase, and the injection API is a plain settable clock.

The three getMillis64 tests are dropped as they no longer describe anything.
One test replaces them, pinning that advanceTestMillis() wraps past
0xFFFFFFFF rather than saturating, since the Throttle wrap tests rely on it.

Also fix eviction in pruneLastNodeInfoCache(): it picked the entry with the
smallest stored stamp, which is the wrong victim once some stamps sit on the
far side of the wrap. It now evicts the largest elapsed time.

* Add CI guard and docs rule against naive millis() comparisons

Fixing the existing sites does not stop the next one being added. The
millis-deadline-check job rejects millis() placed directly next to a comparison
operator, in either order, anywhere in src/. It lives in test_native.yml
alongside suite-count-check, which sets the precedent for a repo-hygiene guard
that CI enforces and bin/run-tests.sh does not.

The correct idioms all subtract before comparing, so none of them match the
pattern. Line comments are stripped first, so documentation is free to name the
broken form - as the guard's own comment and the coding conventions both do.

Writing the check before finishing the sweep turned out to be worth it: it
found roughly 14 sites that a by-hand audit of deadline variables had missed,
including two extra nagCycleCutoff compares, both boot-screen timeouts, and a
6 hour sensor save interval that was also overflowing a uint32_t multiply.

.github/millis-deadline-allowlist.txt covers the cases that are genuinely not
deadline tests. Both current entries are uptime thresholds - "has the device
been up N ms" - with no stored deadline and no event to measure from: a 30s
button holdoff against phantom shutdown from floating pins, and a 10s window
for the OEM boot logo. Each re-crosses its threshold once per wrap, which is
harmless for boot-holdoff logic and not worth new state to avoid. Entries are
keyed on file plus exact source text, without line numbers, so an edit above an
entry does not silently invalidate it.

Locally the guard reports 19 matches before the sweep and 2 after, both
allowlisted.

The Throttle bullet in the coding conventions is rewritten from "prefer
Throttle for rate limiting" to "never compare against millis() directly", lists
all four helpers with when to use which, names the CI guard, and documents the
sentinel hazard with the rebootAtMsec = -1 case that would have become a reboot
loop. Mirrored into AGENTS.md; CLAUDE.md gets a pointer row.

* Trim rollover comments to what the code needs

The comments added with the millis() rollover fixes carried too much of the
investigation that produced them: how many sites were found, which document
recorded them, what the old code used to do. That belongs in the commit history,
not in the source, and some of it was already stale - Power::reboot() still
described the check it disarms as "a naive millis() > deadline" when that
comparison had been fixed in the same series.

What stays is the non-obvious part at each site: which sentinel value the
variable overloads and what it means there, since that differs between call
sites and is what a correct comparison gets wrong. 0 means "not scheduled" for
rebootAtMsec, "renew now" for ntp_renew, and "show indefinitely" in
isOverlayBannerShowing().

Exposition is kept where it earns its place: the Throttle helpers, the uptime
clock's note on why there is no 64-bit variant, and the tests. The Throttle
docs lose only the site count and the "longest interval in the firmware"
statistic, both of which would age badly; the range trade-off between the two
forms is what a caller actually needs.

Comments only - no code changed, verified by diff.

* possible fixes

* Address review feedback on the rollover fixes

- BME680Sensor: checkpoint lastStateSaveMs after a successful write instead of
  at the interval test. The first save (IAQ accuracy >= 2) left it at 0, timing
  the next save from boot, and stamping before the write deferred the retry a
  full period when the write failed. Reads Time::getMillis(), the same clock
  Throttle compares against.

- Throttle: add deadlinePassedAt(now, deadline) for loops that snapshot the
  clock once and test many deadlines; deadlinePassed() now delegates to it.
  NextHopRouter::doRetransmissions() uses it, replacing the inline half-range
  compare adopted from #10227 (nightjoker7) - same arithmetic, credited at the
  call site - and takes its snapshot from Time::getMillis() so setNextTx()
  deadlines and the due test cannot diverge under an injected test clock.

- test_native.yml: set -euo pipefail in the millis-deadline guard, matching the
  sibling suite-count job. Without -e a partially failed scan could report "no
  violations" from truncated output.

- test_packet_signing: build the not-due deadline from Time::getMillis() rather
  than millis(), so the test and the router read one clock.

- test_throttle: cover deadlinePassedAt(), and correct a wrapped-value comment
  (0xFFFFFF00 + 400 is 0x00000090, not 0x00000094).

Two review comments were declined: the AirTime mutex (every airTime-> caller
runs in the single cooperative loop, WebServerThread included) and the
MotionSensor 0-sentinel countdown (the calibration frame is only installed
while a window is open).

* Correct the described failure window of a naive millis() compare

The comments and agent docs said a bare `millis() > deadline` "breaks for ~24
days after the wrap". That figure belongs to the fix, not the bug: it is the
half-range limit of deadlinePassed(), which reads deadlines more than 2^31 ms
ahead as already passed, and the range over which a UINT32_MAX sentinel reads
as passed.

The naive compare's actual failure is an inversion lasting only while the
deadline sits on the far side of the wrap, so it is bounded by the interval:
the action fires immediately and loses its wait, or blocks for about the wait
it should have performed - days for the nRF52 flash-corruption backoff,
one skipped cycle for a seconds-long retransmit timer.

Comments and docs only; the ~24.8 day statements that correctly describe
deadlinePassed()'s own range are left as they were.

clod helped out here

* Restore a monotonic uptime clock and consolidate the wrap counters

Time::getMillisMonotonic() is the getMillis64() shape - a 32-bit wrap
counter carried across reads - promoted to the shared timebase, with
Time::getUptimeSecs() as the derived whole-seconds view. This deliberately
reverses the earlier removal of getMillis64(), and the distinction matters:
removal was right for a lazily-read accumulator with one rare caller, where
a 49.7-day gap between reads silently swallowed a wrap. Here every read is
the poll and AirTime::runOnce() guarantees one per second; the missed-wrap
contract is pinned by a test rather than left as a footnote.

Three private wrap counters collapse into it:

- AirTime::syncNow() takes its seconds from Time::getUptimeSecs() and drops
  its lastSyncMsec checkpoint; window rotation is unchanged.
- DeviceTelemetryModule loses refreshUptime()/uptimeWrapCount/uptimeLastMs;
  uptime_seconds comes from Time::getUptimeSecs(), which also removes the
  0.296s-per-wrap truncation of (0xFFFFFFFF / 1000) * wraps. Its two
  interval checks move to Throttle::hasElapsed().
- HostMetricsModule's copies of those members were never read (its uptime
  comes from /proc/uptime) - deleted.

Not ISR-safe (unguarded mutable carry): ISRs keep using getMillis(), which
stays a pure read. Audited: no interrupt-context file reads getTime(),
getValidTime(), or the new accessors.

test/native-suite-count 44 -> 45: the bump for test_uptime_clock was lost
in a branch history rewrite, leaving every later value off by one -
run-tests.sh reports AMBER and CI's suite-count-check fails on the current
push until this correction.

* Anchor the wall clock in monotonic milliseconds

getTime() computed elapsed-since-time-set as a 32-bit millis() delta, so a
node that took time once and stayed up past 49.7 days reported a wall clock
one full cycle in the past - and last_heard, rx_time, message and position
stamps all inherited it. The anchor is now the 64-bit monotonic count
(timeStartMsec -> timeStartMs64) and the elapsed term is computed in 64-bit,
so the wall clock is exact at any uptime.

All six anchor writers follow: the five hardware-RTC read branches and
perhapsSetRTC(), which keeps a truncated 32-bit copy of the same instant for
its Throttle-checked rate-limit stamps. The test seams anchor the same way.

Two native regression tests drive getTime() across the wrap through the
Time seam - one anchored before the wrap and read after it, one anchored
after a counted wrap - with the test epoch derived from BUILD_EPOCH so the
plausibility window cannot rot as the build date advances.

* Stamp the rx_time placeholder in monotonic uptime seconds

computeRxTimeStamp() stamped Time::getMillis() when the clock was untrusted,
and reconcilePendingRxTimes() back-calculated with a 32-bit millis() delta -
correct within one wrap, but a placeholder older than 49.7 days aliased to a
small elapsed value and reconciled to a plausible-but-wrong recent epoch:
the exact failure has_rx_time exists to prevent, reachable by an ordinary
unattended router whose phone connects two months in.

The placeholder is now Time::getUptimeSecs(). Both stamps come off the
monotonic counter, so the elapsed term is exact at any age and the aliasing
window is gone outright rather than widened. If elapsed somehow exceeds the
epoch itself, the packet stays un-dated (absent, never wrong) instead of
clamping to a pre-1970 value. Defence in depth: a placeholder that leaks
needs ~50 years of uptime to cross MIN_PLAUSIBLE_EPOCH, where milliseconds
took 18.3 days.

The stream-API reconciliation tests keep their scenarios with the placeholder
unit switched, and ScopedTimeFixture resets the monotonic carry so uptime
seconds are deterministic per case.

* Date nodes heard before the clock arrives, without polluting last_heard

A node first heard while the wall clock was untrusted got no last_heard at
all, and nothing backfilled it once time arrived - the phone showed "Last
heard: unknown" for a node it had just announced. The arrival instant now
waits in a RAM-only sidecar (NodeNum -> uptime seconds, 32 slots,
reuse-oldest - the RouteHealth shape) and is converted to a real epoch on
the clock-becoming-trusted transition, beside the existing rx_time
reconciliation. last_heard itself never holds anything but a real epoch or
0: it persists to flash and the warm tier, where an uptime-relative value
would be meaningless after reboot.

The sidecar's write sites are updateFrom()'s no-trusted-clock path (the
rx_time placeholder already carries the arrival instant, so this is a store,
not a second clock read) and addFromContact's anti-eviction stamps, which
previously wrote a bare getTime() - boot-relative seconds on a clockless
node, the exact value lastHeardIsWallClock() exists to catch. Eviction
ranking honours the stamps: heard-this-boot outranks every stored epoch,
ordered among themselves, so a stamped contact is not the first victim.

PhoneAPI re-reads last_heard at nodeinfo send time: a record prefetched
before the clock became trusted can carry 0 while the store has since been
backfilled, and re-reading at the pop makes handshake ordering (time-set vs
node-list download) irrelevant. Backfill never moves last_heard backwards
and skips the pathological elapsed-exceeds-epoch case. A node evicted to
the warm tier before time arrives is still absorbed with last_heard 0 -
same as before, bounded to the untrusted window.

* Update the agent docs for the monotonic timebase

The conventions bullet asserted there is deliberately no 64-bit millis; the
monotonic uptime clock restored for timestamps changes that contract. State
the split explicitly: Throttle for deadlines and intervals (no carry state),
Time::getMillisMonotonic()/getUptimeSecs() for timestamps, polled by
construction and not ISR-safe.

* Publish the monotonic wrap carry from a single writer

getMillisMonotonic() was a read-modify-write on two unguarded statics, and it
is reached off the main loop: the nRF52 Bluefruit task via
onFromRadioAuthorize() -> PhoneAPI::getFromRadio -> getValidTime(), and the
portduino civetweb workers via the same path. Two readers interleaving inside
the wrap window could each increment the carry, putting every uptime and
wall-clock reading 2^32 ms ahead for the rest of the boot - a permanent ~49.7
day jump in rx_time, last_heard and ClientNotification.time.

Readers no longer write. serviceMonotonic() publishes a snapshot behind a
seqlock and is the only writer; a reader adds its own unsigned elapsed time to
that snapshot, which is exact across the wrap, so it never inspects the
boundary and cannot miscount it. The main loop publishes every iteration, so
the once-per-49.7-days obligation now has the whole window of margin instead of
resting on an instruction-wide race.

AirTime was the guaranteed poller and is now a pure reader, so the two airtime
wrap tests step the clock the way loop() does. The test clock itself is atomic
so a suite can drive it from one thread while others read.

* Re-arm the GPS ephemeris hold when none is in force

The rollover sweep guarded the hold re-arm with `fixHoldEnds != 0 &&`, which
reads like the sentinel rule but inverts this site. The comparison it replaced,
`(fixHoldEnds + GPS_THREAD_INTERVAL) < millis()`, was always true when nothing
was armed - that was the point, since 0 means "not holding" and so is a reason
to arm. With the guard, a publish that cleared the hold without sleeping (the
`shouldPublish && !tooLong && !holdExpired` path, which does not call down())
left hasValidLocation set and prev_fixQual non-zero, so no disjunct held:
nothing re-armed, nothing published, and the receiver stayed powered at the
200ms poll until searchedTooLong() fired.

State the question positively instead. fixHoldInForce() is the only place the
sentinel is interpreted, and both of runOnce()'s decisions derive from it - the
asymmetry is now visible rather than implied, since arming does not require a
prior hold but expiring does. Its `!= 0` test is not redundant with the
arithmetic: deadlinePassed() is an unsigned half-range test, so past 2^31 ms of
uptime the sentinel reads as a deadline ~24.9 days in the future.

Kept beside its caller rather than in a header; the native test build compiles
GPS.cpp, so the suite declares the prototypes.

Also converts the getACK() wait to isWithinTimespanMs(start, interval): it has
both the start instant and the interval in hand, which gives the full 49.7-day
range instead of 24.8 days ahead, and takes its anchor from Time::getMillis()
so the wait is injectable.

* Date the NodeInfo reply window in uptime seconds

The 12h reply-suppression stamp regressed from wrap-immune 64-bit seconds to
raw 32-bit milliseconds, and pruneLastNodeInfoCache() evicts only by node count
and DB membership - never by age. A stable mesh under the node cap therefore
keeps every stamp indefinitely, and once uptime passes 49.7 days an old one
aliases back into the window: `now - stamp` computes as ~0 and a legitimate
NodeInfo request goes unanswered for up to 12h. It self-heals and repeats once
per wrap cycle.

Store Time::getUptimeSecs() instead, which does not wrap for 136 years, and
drop the millisecond conversion the previous shape needed. Entries past the
window are now evicted too: they can only ever decide "don't suppress".

N8-N11 cover the window from both sides, and N10 pins the regression - it needs
a full 2^32 ms of uptime to elapse, not merely a crossing of the boundary,
because that is when a millisecond stamp reads as "answered this instant".

tearDown() now restores the injected clock and C14's region and TX bucket. A
failing assertion aborts the test body, so restoring at the end of it leaked
that state into every later case.

* Update the agent docs for the single-writer clock and sentinel direction

Two rules the preceding three commits changed.

The monotonic clock is no longer maintained by whoever happens to read it:
serviceMonotonic() is the only writer, readers are pure, and calling it from
anywhere but the main loop reintroduces the double-count.

The sentinel guidance gained the half it was missing. It named UINT32_MAX as a
sentinel while prescribing an idiom that only covers 0, and it assumed the
sentinel always means "suppress" - at the GPS fix-hold site it meant "fire",
which is how that regression passed review looking like the rule.

* Name the fix-hold expiry predicate and arm it from the injected clock

holdJustExpired() gives the second reading of the fixHoldEnds sentinel a
name beside the first, so both are pinned by test/test_gps_fix_hold/ and
neither can be respelled at the call site. The old inline form could not
be tested: written as a literal, its guard folds at compile time and the
assertion asserts nothing.

The arm site used bare millis() while the evaluation reads the Throttle
clock; same value in production, but it kept that write out of reach of
Time::setTestMillis(). Remap a deadline that lands on 0, which would
otherwise read as no hold at all.

* Share the extend formula between the clock's reader and writer

getMillisMonotonic() and serviceMonotonic() carried byte-identical wrap
arithmetic. A one-sided edit to either would drift the published carry
from what readers report, so keep one copy.

* Trim the NodeInfo dedup comment to the house limit

* todo note for potential future imrpovments

* fix some simple deadlines

* Trim the hold-expiry test comment to the house limit

* Fix non-blocking uptime publication and pre-clock recency edges (#29)

* fix(time): avoid blocking monotonic readers

* test(time): make paused-publisher check deterministic

* fix(time): address review portability gaps

* Init the eviction sentinel to the newest possible recency

EvictionRecency{} is {0, false}, which evictionRecencyOlder() ranks as older than
every candidate: without the oldestIndex/oldestBoringIndex guards nothing would
ever be selected and a full node DB would stop evicting entirely.

Init to the genuine maximum instead, so the sentinel is correct on its own. The
index guards stay: two independent reasons the scan is right beats one.

* Keep the deadline-guard check name branch protection matches

The guard was widened to cover Time::getMillis() and unqualified getMillis(),
and renamed to suit. Upstream branch protection matches required checks by name,
so a rename means the old name never reports and merges block on a check that
will never arrive.

Widen the guard, keep the name; the descriptive text carries the broader scope.

* Correct native-suite-count to 47 after the develop merge

Upstream #11293 added test_nmea_wpl and took develop's count to 43; this branch
had independently reached 46. Merging develop resolved the counter textually,
keeping 46, while the directory set became the union of both sides at 47.

The suite-count CI gate fails on the mismatch, and it gates the native test jobs,
so the tests themselves were being skipped.

* test(uptime): make the wrap fall where the comment says it does

The concurrent-reader case started at 0xFFFFF000, leaving 0x1000 to the wrap, so
the 0x800 advance annotated "cross the wrap" fell short and the wrap actually
happened during the following 60s advance.

Start at 0xFFFFF800 instead, so the first advance lands exactly on the wrap while
the readers are running and the second is the ordinary time after it - the shape
both comments already described. Total elapsed is unchanged, so the closing
assertion still holds.

* Respond to human comments

* Did I ever tell you about the time I went to Shelbyville? I wore an onion on my belt, which was the style at the time.

* Convert the I2S nag deadline develop dragged in

The HAS_I2S_SPEAKER_NRF52 RTTTL block arrived from develop with a raw
nagCycleCutoff >= millis(), which the deadline guard rejects. Use the same
Throttle::deadlinePassed() form as the two sibling paths in this function.

* Arm the LittleFS format guard with a flag, not a zero timestamp

preFSBegin() runs in the first millisecond of boot, so millis() can legitimately
return 0 there. Both readers of last_format_ms treated 0 as "nothing formatted
this boot", which would skip the repeat-corruption escalation and let a dead
flash reformat-loop instead of reporting FLASH_CORRUPTION_UNRECOVERABLE.

* Note the single-thread contract on AirTime

* Note the AirTime locking TODO, and tighten the thread note

The two constant getters are not constrained, and getSilentMinutes() reads the
buckets without rotating them, so "the accessors mutate" was not accurate.

* trunk: ignore trufflehog false positives on millis-wrap test constants

test_throttle and test_uptime_clock pin dense clusters of hex boundary
constants (0xFFFFFF00u and neighbors) to exercise 32-bit millis()
rollover. trufflehog's Lob detector stitches nearby hex literals into
one candidate string, and the result happens to match a Lob API key
shape - not a secret, just test fixtures.

Same pattern already used for the gitleaks/nodedb-fixture false
positive in this file.

Jonathan BennettandClaude Fable 5 5baad2e2a8 logging: compile out LOG_TRACE by default, demote chatty DEBUG lines, drop redundant logs (#11391)
* logging: gate LOG_TRACE behind MESHTASTIC_TRACE_LOGGING, drop redundant reclock logs

LOG_TRACE now compiles out by default so trace-level diagnostics cost no
flash; enable with -DMESHTASTIC_TRACE_LOGGING. Portduino keeps it on for
the traceFilename packet-trace feature.

Remove the 66 caller-side I2C reclock/restore log lines in the telemetry
sensors: ReClockI2C::setClock/restoreClock already log both frequencies
internally (now at trace level, since they fire every sensor read).

Also unify near-duplicate literals (colon/case/punctuation variants) so
linker string dedup applies, and drop an information-free bare 'done'.

With LOG_TRACE compiled out by default, per-iteration chatter (packet

UI runState traces) now costs no flash on device builds while remaining
one -DMESHTASTIC_TRACE_LOGGING away. 108 lines demoted, 4 information-

Replaces 27 log-only #ifdef GPS_DEBUG blocks across GPS.cpp,
PositionModule, MeshService, and GPSStatus.h with a single-line
LOG_DEBUG_GPS() call (src/gps/GPSLog.h, modeled on LOG_MIGRATION:
value-gated, ((void)0) when off). Blocks containing declarations,
control flow, hexDump, or nested conditionals keep an explicit
'#if GPS_DEBUG' guard. RTC.cpp's per-reading raw time dumps and
per-candidate rejection chatter fold under the same gate; quality
transitions and boot-time seeding stay at debug.

Also fixes the '// define GPS_DEBUG' missing-# typo in two variant
headers and updates all seven commented examples to the value form
('#define GPS_DEBUG 1') required by the value-based gate.

* logging: address review feedback on the terseness audit

- 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.

Printf specifier sequences are byte-identical on all 37 touched lines apart
from the 6 deliberate %x/%u -> %08x node-ID widenings, all on uint32_t args.

Thomas Göttgens cdd996248c Release the opaque relay copy the interface declines to send (#11262)
relayOpaquePacket() allocates a copy and returns Router::send(relay) == ERRNO_OK, discarding ERRNO_SHOULD_RELEASE. The interface returns that for NODENUM_BROADCAST_NO_LORA, so the copy is never freed and one pool slot leaks per frame.

The opaque path is reached for packets on a channel we have no key for, so no key or PSK is needed: a frame with an unknown channel hash, to=NODENUM_BROADCAST_NO_LORA, a nonzero id and hop_limit>0 leaks a slot, and roughly MAX_PACKETS of them exhaust the pool until reboot.

#11087 fixed this pattern in perhapsRebroadcast and the retransmission paths but did not cover relayOpaquePacket, which was added separately with the opaque relay path.

Andrew Yong 0ae44d7017 fix(router): null-check packetPool/clientNotificationPool allocations (#10948)
On platforms where these pools are heap-backed (MemoryDynamic - used
whenever there isn't enough static RAM for a fixed pool, e.g.
ARCH_STM32WL or BOARD_HAS_PSRAM), allocCopy()/allocZeroed() return
nullptr on allocation failure and already log a warning, but most
callers dereferenced the result unconditionally. Under real heap
pressure this reliably produced a HardFault - reproduced on STM32WL
hardware under sustained mesh traffic, including the RX entry point
(RadioLibInterface::handleReceiveInterrupt) where every received
packet is allocated.

Adds null checks at all call sites that were missing one, mirroring
the guard pattern already used correctly elsewhere in the same files
(e.g. RadioInterface.cpp's sendErrorNotification). On allocation
failure, callers now skip the send/retransmission/notification and
log nothing further (the allocator already did) rather than crash.

* TrafficManagement: flat unified cache + persistent next-hop overflow store

Reworks the TrafficManagementModule cache layer (policing behaviour unchanged
from upstream) and adds a routing-hint overflow store:

- Flatten the ring: replace the cuckoo-hashed unified cache and the bucketed
  PSRAM NodeInfo index with plain flat arrays + linear scan (same idiom as
  WarmNodeStore). At LoRa packet rates an O(n) scan of the cache is negligible,
  and it removes a large amount of hashing/displacement complexity. The cache
  entry is 11 B; timestamps use a uniform +1 presence-offset so a 0 byte always
  means "empty" across every sub-store. Adds rebaseEpoch() so cached state
  survives the ~19 h relative-timestamp horizon instead of being flushed.

- Next-hop overflow cache: setNextHop/getNextHopHint store a confirmed last-byte
  relay for a destination, written only from NextHopRouter's ACK-confirmed
  decision (and mirrored from TraceRoute). NextHopRouter::getNextHop falls back
  to this cache when the hot NodeDB has no hint, so DMs/relays to long-tail
  nodes keep routing after the node ages out of NodeInfoLite.

- Persistence: preloadNextHopsFromNodeDB warm-starts the cache from persisted
  NodeInfoLite hints on first maintenance pass; next_hop entries are kept alive
  across the maintenance sweep (no TTL) and never clobbered by a stale preload.

All packet-policing logic (rate limit, position dedup, unknown-packet drop,
NodeInfo direct response, hop exhaustion) is the existing upstream behaviour,
untouched. HAS_TRAFFIC_MANAGEMENT defaults on so the module is compiled in. (see note).

Tests: upstream policing suite now actually runs (adds the MeshTypes.h include
that gates HAS_TRAFFIC_MANAGEMENT) plus 4 next-hop tests. Role-aware throttles,
politeness, precision clamp, port-interval and mesh-radius gating — and the
rate-limit >255 saturation fix — are deferred to the advanced-TMM branch.

Note: default dedup movement grid moves to ~91m, which also means 1.5km required to end up with the same signature position - coarser and therefore further than before.

* TrafficManagement: fix cppcheck constVariablePointer warning

`node` in preloadNextHopsFromNodeDB() is never written through — mark
it const to satisfy cppcheck's constVariablePointer check in CI.

* Add multi-hop NextHop recovery tests and unit tests for routing reliability

- Introduced a new test suite for multi-hop NextHop directed-message delivery and relay recovery in `test_nexthop_multihop_recovery.py`. This includes tests for end-to-end delivery and recovery after relay drop.
- Implemented unit tests in `test_main.cpp` for NextHop routing reliability mitigations, covering:
  - M1: Ambiguity-aware last-byte resolution.
  - M2: NextHopRouter's strict-neighbor gate and hop limit checks.
  - M3: Route-health freshness and failure decay.
- Enhanced mock classes to facilitate controlled testing of node behaviors and routing logic.

* grafting fixed

* Address Copilot review for PR #10735 (NextHop improvements)

- docs/nexthop-routing-reliability.md: update status from "no code
  changes yet" to reflect that mitigations and tests are implemented

RAM pressure and MIGRATION_VERBOSE concerns addressed upstream in
PR2.5 (per-platform TRAFFIC_MANAGEMENT_CACHE_SIZE) and PR2 (verbose
default=0) respectively; (0,0) sentinel fixed in PR2.5.

* WarmStore: cache device role + protected category in last_heard low bits

Steal the low 6 bits of WarmNodeEntry.last_heard to carry an evicted node's
device role (4 bits) and a protected category (2 bits) for the hop-trim path,
at zero record-size cost (entry stays 40 B; no RAM/flash growth). The high bits
remain a real unix-seconds timestamp, quantised to 64 s — ample for warm LRU
ordering of long-tail nodes.

- absorb() packs role/protectedCat; place()/ring replay store the raw word so
  metadata round-trips through flash. LRU compares masked time (warmTimeOf).
- take() rehydration masks the metadata bits and restores the cached role so a
  re-admitted node isn't stuck at CLIENT until its next NodeInfo.
- NodeDB classifies the category (favorite/ignored/verified -> Flag;
  tracker/sensor/tak_tracker -> Role) at each eviction site.
- WarmNodeStore::lookupMeta() exposes role/category to consumers.
- Bump WARM_RING_MAGIC (WRNG->WRN2): old rings read as erased and rebuild;
  warm data is a non-critical evictee cache, so discard-on-upgrade is safe.

Tests: test_warm_store 11/11 (new meta round-trip + quantisation-aware ordering);
NodeDB compiles (test_nodedb_blocked 4/4).

Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

* WarmStore: migrate v1 rings/files by discarding last_heard, not the data

Previously the WRNG->WRN2 magic bump treated old rings as erased, discarding all
warm entries — including the PKI public keys that let evicted nodes keep
decrypting DMs. Instead, read v1 (WRNG / WRM1) records and keep each node's
identity + public key, discarding only last_heard (its low bits would otherwise
be misread as the new role/protected metadata). Records re-rank and re-learn
their role on next contact.

- Ring backend (nRF52840): ringReadHeader accepts both magics and reports v1 via
  an out-param; replay zeroes last_heard for v1 records. If the active head page
  is v1, force a rotation so new v2 records never land in a v1-headered page
  (which would discard their freshly-set role on the next load). Legacy pages
  convert to v2 as the ring rotates.
- File backend (warm.dat): bump WARM_STORE_MAGIC WRM1->WRM2; accept WRM1, verify
  CRC against the stored bytes, then discard last_heard and mark dirty so the
  next save rewrites as v2.

Tests: test_warm_store 12/12 (adds test_ws_v1_migration_discardsLastHeard:
key survives, role/protected reset).

Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

* WarmStore: guard role bit-width + test eviction carries role/protected

- static_assert that the device role enum still fits the 4-bit warm metadata
  field (WARM_ROLE_MASK); fails the build loudly if a new role is added past 15
  rather than silently truncating role on eviction. (Max role today = 12.)
- Add test_migration_carriesRoleAndProtectedIntoWarm: a demoted TRACKER lands in
  the warm tier with its key, role=TRACKER and protected category=Role; a demoted
  CLIENT carries role=CLIENT/None. Exercises the NodeDB eviction path +
  warmProtectedCategory classification (the warm-store unit tests only cover
  absorb() directly).

Tests: test_nodedb_blocked 5/5.

I thought git would be smart enough to understand all the whitespace changes but even with all the flags I know to make it ignore theses it still blows up if there are identical changes on both sides.

3c25652cdf If a packet is heard multiple times, rebroadcast using the highest hop limit (#5534)
* If a packet is heard multiple times, rebroadcast using the highest hop limit

Sometimes a packet will be in the TX queue waiting to be transmitted,
when it is overheard being rebroadcast by another node, with a higher
hop limit remaining. When this occurs, modify the pending packet in
the TX queue to avoid unnecessarily wasting hops.

* Reprocess instead of modifying queued packet

In order to ensure that the traceroute module works correctly, rather
than modifying the hop limnit of the existing queued version of the
packet, simply drop it ifrom the queue and reprocess the version of the
packet with the superior hop limit.

* Update protobufs submodule

* Merge upstream/develop into overheard-hoptimisation branch

Resolved conflicts in:
- src/mesh/FloodingRouter.cpp: Integrated hop limit optimization with refactored duplicate handling
- src/mesh/MeshPacketQueue.h: Kept both hop_limit_lt parameter and new find() method

* Improve method naming and code clarity

- Rename findPacket() to getPacketFromQueue() for better clarity
- Make code DRY by having find() use getPacketFromQueue() internally
- Resolves method overloading conflict with clearer naming

* If a packet is heard multiple times, rebroadcast using the highest hop limit

Sometimes a packet will be in the TX queue waiting to be transmitted,
when it is overheard being rebroadcast by another node, with a higher
hop limit remaining. When this occurs, modify the pending packet in
the TX queue to avoid unnecessarily wasting hops.

* Improve router role checking using IS_ONE_OF macro

- Replace multiple individual role checks with cleaner IS_ONE_OF macro
- Add CLIENT_BASE support as suggested in PR #7992
- Include MeshTypes.h for IS_ONE_OF macro
- Makes code more maintainable and consistent with other parts of codebase

* Apply IS_ONE_OF improvement to NextHopRouter.cpp

- Replace multiple individual role checks with cleaner IS_ONE_OF macro
- Add CLIENT_BASE support for consistency
- Include MeshTypes.h for IS_ONE_OF macro
- Matches the pattern used in FloodingRouter.cpp

* Create and apply IS_ROUTER_ROLE() macro across codebase

- Add IS_ROUTER_ROLE() macro to meshUtils.h for consistent router role checking
- Update FloodingRouter.cpp to use macro in multiple locations
- Update NextHopRouter.cpp to use macro
- Include CLIENT_BASE role support

* Core Changes:
- Add hop_limit field to PacketRecord (17B→20B due to alignment)
- Extend wasSeenRecently() with wasUpgraded parameter
- Enable router optimization without duplicate app delivery
- Handle ROUTER_LATE delayed transmission properly

Technical Details:
- Memory overhead: ~4000 bytes for 1000 records
- Prevents duplicate message delivery while enabling routing optimization
- Maintains protocol integrity for ACK/NAK handling
- Supports upgrade from hop_limit=0 to hop_limit>0 scenarios

* Delete files accdentally added for merge

* Trunk formatting

* Packets are supposed to be unsigned. Thankfully, it's only a log message.

* Upgrade all packets, not just 0 hop packets.

* Not just unsigned, but hex. Updating packet log IDs.

* Fixed order of operations issue that prevented packetrs from being removed from the queue

* Fixing some bugs after testing. Only storing the maximum hop value in PacketRecord which makes sense. Also, updating messaging to make more sense in the logs.

* Fixed flow logic about how to handle re-inserting duplicate packets. Removed IS_ROUTER_ROLE macro and replaced it with better isRebroadcaster().

* Add logic to re-run modules, but avoid re-sending to phone.

* Refactor how to process the new packet with hops. Only update nodeDB and traceRouteModule.

* - Apply changes to both FloodingRouter and NextHopRouter classes to make packets mutable for traceroute
- MESHTASTIC_EXCLUDE_TRACEROUTE guard for when we don't want traceroute

* Allow MeshPacket to be modified in-place in processUpgradePacket

* let's not make a copy where a copy is unncessary.

* Simplify Ublox code

Ublox comes in a myriad of versions and settings. Presently our
configuration code does a lot of branching based on versions being
or not being present.

This patch adds version detection earlier in the piece and branches
on the set gnssModel instead to create separate setup methods for Ublox 6,
Ublox 7/8/9, and Ublox10.

Additionally, adds a macro to make the code much shorter and more
readable.

* InkHUD UI for E-Ink (#6034)

* Decouple ButtonThread from sleep.cpp
Reorganize sleep observables. Don't call ButtonThread methods inside doLightSleep. Instead, handle in class with new lightsleep Observables.

* InkHUD: initial commit (WIP)
Publicly discloses the current work in progress. Not ready for use.

* feat: battery icon

* chore: implement meshtastic/firmware #5454
Clean up some inline functions

* feat: menu & settings for "jump to applet"

* Remove the beforeRender pattern
It hugely complicates things. If we can achieve acceptable performance without it, so much the better.

* Remove previous Map Applet
Needs re-implementation to work without the beforeRender pattern

* refactor: reimplement map applet
Doesn't require own position
Doesn't require the beforeRender pattern to precalculate; now all-at-once in render
Lays groundwork for fixed-size map with custom background image

* feat: autoshow
Allow user to select which applets (if any) should be automatically brought to foreground when they have new data to display

* refactor: tidy-up applet constructors
misc. jobs including:
- consistent naming
- move initializer-list-only constructors to header
- give derived applets unique identifiers for MeshModule and OSThread logging

* hotfix: autoshow always uses FAST update
In future, it *will* often use FAST, but this will be controlled by a WindowManager component which has not yet been written.
Hotfixed, in case anybody is attempting to use this development version on their deployed devices.

* refactor: bringToForeground no longer requests FAST update
In situations where an applet has moved to foreground because of user input, requestUpdate can be manually called, to upgrade to FAST refresh.
More permanent solution for #23e1dfc

* refactor: extract string storage from ThreadedMessageApplet
Separates the code responsible for storing the limited message history, which was previously part of the ThreadedMessageApplet.
We're now also using this code to store the "most recent message". Previously, this was stored in the `InkHUD::settings` struct, which was much less space-efficient.
We're also now storing the latest DM, laying the foundation for an applet to display only DMs, which will complement the threaded message applet.

* fix: text wrapping
Attempts to fix a disparity between `Applet::printWrapped` and `Applet::getWrappedTextHeight`, which would occasionally cause a ThreadedMessageApplet message to render "too short", overlapping other text.

* fix: purge old constructor
This one slipped through the last commit..

* feat: DM Applet
Useful in combination with the ThreadedMessageApplets, which don't show DMs

* fix: applets shouldn't handle events while deactivated
Only one or two applets were actually doing this, but I'm making a habit of having all applets return early from their event handling methods (as good practice), even if those methods are disabled elsewhere (e.g. not observing observable, return false from wantPacket)

* refactor: allow requesting update without requesting autoshow
Some applets may want to redraw, if they are displayed, but not feel the information is worth being brought to foreground for. Example: ActiveNodesApplet, when purging old nodes from list.

* feat: custom "Recently Active" duration
Allows users to tailor how long nodes will appear in the "Recents" applets, to suit the activity level of their mesh.

* refactor: rename some applets

* fix: autoshow

* fix: getWrappedTextHeight
Remove the "simulate" option from printWrapped; too hard to keep inline with genuine printing (because of AdafruitGFX Fonts' xAdvance, mabye?). Instead of simulating, we printWrapped as normal, and discard pixel output by setting crop. Both methods are similarly inefficient, apparently.

* fix: text wrapping in ThreadedMessageApplet
Wrong arguments were passed to Applet::printWrapped

* feat: notifications for text messages
Only shown if current applet does not already display the same info. Autoshow takes priority over notifications, if both would be used to display the same info.

* feat: optimize FAST vs FULL updates
New UpdateMediator class counts the number of each update type, and suggets which one to use, if the code doesn't already have an explicit prefence. Also performs "maintenance refreshes" unprovoked if display is not given an opportunity to before a FULL refresh through organic use.

* chore: update todo list

* fix: rare lock-up of buttons

* refactor: backlight
Replaces the initial proof-of-concept frontlight code for T-Echo
Presses less than 5 seconds momentarily illuminate the display
Presses longer than 5 seconds latch the light, requiring another tap to disable
If user has previously removed the T-Echo's capacitive touch button (some DIY projects), the light is controlled by the on-screen menu. This fallback is used by all T-Echo devices, until a press of the capacitive touch button is detected.

* feat: change tile with aux button
Applied to VM-E290.
Working as is, but a refactor of WindowManager::render is expected shortly, which will also tidy code from this push.

* fix: specify out-of-the-box tile assignments
Prevents placeholder applet showing on initial boot, for devices which use a mult-tile layout by default (VM-E290)

* fix: verify settings version when loading

* fix: wrong settings version

* refactor: remove unimplemented argument from requestUpdate
Specified whether or not to update "async", however the implementation was slightly broken, Applet::requestUpdate is only handled next time WindowManager::runOnce is called. This didn't allow code to actually await an update, which was misleading.

* refactor: renaming
Applet::render becomes Applet::onRender.
Tile::displayedApplet becomes Tile::assignedApplet.
New onRender method name allows us to move some of the pre and post render code from WindowManager into new Applet::render method, which will call onRender for us.

* refactor: rendering
Bit of a tidy-up. No intended change in behavior.

* fix: optimize refresh times
Shorter wait between retrying update if display was previously busy.
Set anticipated update durations closer to observed values. No signifacant performance increase, but does decrease the amount of polling required.

* feat: blocking update for E-Ink
Option to wait for display update to complete before proceeding. Important when shutting down the device.

* refactor: allow system applets to lock rendering
Temporarily prevents other applets from rendering.

* feat: boot and shutdown screens

* feat: BluetoothStatus
Adds a meshtastic::Status object which exposes the state of the Bluetooth connection. Intends to allow decoupling of UI code.

* feat: Bluetooth pairing screen

* fix: InkHUD defaults not honored

* fix: random Bluetooth pin for NicheGraphics UIs

* chore: button interrupts tested

* fix: emoji reactions show as blank messages

* fix: autoshow and notification triggered by outgoing message

* feat: save InkHUD data before reboot
Implemented with a new Observable. Previously, config and a few recent messages were saved on shutdown. These were lost if the device rebooted, for example when firmware settings were changed by a client. Now, the InkHUD config and recent messages saved on reboot, the same as during an intentional shutdown.

* feat: imperial distances
Controlled by the config.display.units setting

* fix: hide features which are not yet implemented

* refactor: faster rendering
Previously, only tiles which requested update were re-rendered. Affected tiles had their region blanked before render, pixel by pixel. Benchmarking revealed that it is significantly faster to memset the framebuffer and redraw all tiles.

* refactor: tile ownership
Tiles and Applets now maintain a reciprocal link, which is enforced by asserts. Less confusing than the old situation, where an applet and a tile may disagree on their relationship. Empty tiles are now identified by a nullptr *Applet, instead of by having the placeholderApplet assigned.

* fix: notifications and battery when menu open
Do render notifications in front of menu; don't render battery icon in front of menu.

* fix: simpler defaults
Don't expose new users to multiplexed applets straight away: make them enable the feature for themselves.

* fix: Inputs::TwoButton interrupts, when only one button in use

* fix: ensure display update is complete when ESP32 enters light sleep
Many panels power down automatically, but some require active intervention from us. If light sleep (ESP32) occurs during a display update, these panels could potentially remain powered on, applying voltage the pixels for an extended period of time, and potentially damaging the display.

* fix: honor per-variant user tile limit
Set as the default value for InkHUD::settings.userTiles.maxCount in nicheGraphics.h

* feat: initial InkHUD support for Wireless Paper v1.1 and VM-E213

* refactor: Heard and Recents Applets
Tidier code, significant speed boost. Possibly no noticable change in responsiveness, but rendering now spends much less time blocking execution, which is important for correction functioning of the other firmware components.

* refactor: use a common pio base config
Easier to make any future PlatformIO config changes

* feat: tips
Show information that we think the user might find helpful. Some info shown first boot only. Other info shown when / if relevant.

* fix: text wrapping for '\n'
Previously, the newline was honored, but the adojining word was not printed.

* Decouple ButtonThread from sleep.cpp
Reorganize sleep observables. Don't call ButtonThread methods inside doLightSleep. Instead, handle in class with new lightsleep Observables.

* feat: BluetoothStatus
Adds a meshtastic::Status object which exposes the state of the Bluetooth connection. Intends to allow decoupling of UI code.
