Ben MeadorsandGitHub 8d20606203 feat(config): make position & telemetry broadcast opt-in (#10929)
Position sharing was opt-out (the default primary channel shipped
position_precision=13) while device telemetry was already opt-in, and a
normal firmware upgrade preserves saved config, so existing nodes stayed
position-on. This makes both broadcasts opt-in, both on a fresh flash and via
a one-time migration for upgrading nodes.

- Fresh default: initDefaultChannel now sets position_precision=0.
- One-time migration in loadFromDisk, gated on a dedicated
  POSITION_TELEMETRY_OPTIN_VER (26) watermark kept separate from
  DEVICESTATE_CUR_VER (bumping that would re-run the NodeDatabase v24
  legacy decoder on already-migrated v25 DBs): disables position broadcast
  on PUBLIC/default-PSK channels and forces every device-telemetry
  mesh-broadcast flag plus the MQTT map-report location off.
- Private-PSK channels are left untouched: a channel with a custom key is a
  deliberate trusted-group setup, so its configured precision is preserved.
- Idempotent: ordinary saves never re-stamp .version, so a user who
  re-enables sharing is not re-disabled on the next boot.
- Added pure channelFileUsesPublicKey() (operates on the raw ChannelFile,
  since the channels singleton isn't initialized during loadFromDisk) and
  refactored Channels::usesPublicKey() to delegate to it.
- New test/test_optin_migration native suite (14 cases).

d846780a9b More fuzz tests and small fixes for the findings (#10864)
* first pass tests

* more tests

* Fix two crafted-admin-packet crashes found by the E5 fuzzer

Both are reachable from an authorized admin (local from==0, admin channel,
or PKC) - remote DoS:

1. SIGFPE in LoRa config validation. A set_config LoRaConfig with
   use_preset=false and bandwidth=0 makes freqSlotWidth 0, so numFreqSlots
   is 0 and `hash(name) % numFreqSlots` (RadioInterface.cpp) divides by
   zero. Guard the modulo; the existing channel_num check then rejects/
   clamps the config.

2. Stack overflow in Channels::getKey. A SECONDARY channel at the primary
   slot with an empty PSK recursed into getKey(primaryIndex) forever. Skip
   the primary-key borrow when chIndex == primaryIndex.

Re-enable the E5 admin fuzzer to hit both triggers again (use_preset both
ways incl. bandwidth 0, plus the set_channel tag) as regression guards.

* Correct fuzz-test invariants after the crash fixes

- E5 admin fuzz: node eviction under a filling NodeDB is legitimate, so
  assert only the bounded-count invariant, not that a specific seed node
  survives 6000 mutating ops.
- TMM blitz: scope off the nodeinfo direct-response send path (it needs a
  fully-wired MeshService/phone queue the fixture doesn't provide; the
  deterministic directResponse tests cover it). The crafted-nodenum
  rate/unknown/position cache stress is unchanged.

* realistic tests

* test: dedup fuzz RNG into shared test/support/DeterministicRng.h

The four in-tree fuzz suites (test_fuzz_decode, test_fuzz_packets,
test_hop_scaling, test_traffic_management) each carried a byte-identical
copy of the seeded 64-bit LCG (rngSeed/rngNext/rngByte/rngRange). Hoist
it into one shared header so there is a single generator to reason about
and no risk of the copies drifting. static inline keeps per-suite state
per translation unit and avoids -Wunused-function for suites that don't
use every helper. Also corrects a stale comment in test_traffic_management
(the blitz's nodeinfo direct-response path is intentionally left off).

No behavioral change: same constants, same per-suite seeds.

clod helped too

* test: fuzz uncovered ProtobufModule handlers and the MQTT downlink ingress

Extend the in-tree fuzz coverage to packet sources that previously had
none:

- test_fuzz_packets E8/E9/E10: drive PositionModule, DeviceTelemetryModule
  and NeighborInfoModule at handleReceivedProtobuf directly (via using-shims,
  bypassing the ProtobufModule reply/send path so no router is needed). The
  fixture already stands up nodeDB/service/channels, and nodeStatus/powerStatus
  are auto-initialized in main.cpp, so no new globals are required. Adds a
  shared fuzzRxHeader() helper for crafting adversarial RX packet headers.
- test_fuzz_decode: add meshtastic_KeyVerification to the decode table. The
  KeyVerification and StoreForward handler paths are documented as decode-level
  only, with the concrete reason each is intrinsic (private-state gating /
  PSRAM + self-pointer wiring), not a fixture gap.
- test_mqtt: test_receiveFuzzServiceEnvelope blitzes the non-RF broker-push
  ingress (onReceiveProto) two ways - raw garbage bytes that must fail envelope
  decode cleanly, and a well-formed ServiceEnvelope wrapping a crafted inner
  MeshPacket over crafted channel_id/gateway_id - exercising the channel match,
  isFromUs, XEdDSA receive policy and perhapsDecode chain. Adds a deliverRaw()
  passthrough to MQTTUnitTest.

All under the coverage env (ASan/LSan). No firmware/src changes. Full sweep
GREEN 27/27, 544 cases.

* Harden LoRa/channel config against crafted admin messages; consolidate test helpers

Production (review findings on the hot-fuzz crash fixes):
- Clamp bandwidth at the source (clampBandwidthKHz) in checkOrClampConfigLora
  and applyModemConfig so numFreqSlots can never be 0 for any consumer; a
  bandwidth-0 set_config previously passed validation and re-armed the SIGFPE
  on the next applyModemConfig.
- Guard applyModemConfig's hash % numFreqSlots (the validator's sibling modulo
  was fixed earlier but this one was still unguarded).
- Enforce the primary-channel invariant in Channels::onConfigChanged: a config
  demoting every slot now re-promotes the stale SECONDARY slot (keeping its
  key) or restores the default channel if the slot is DISABLED, instead of
  leaving every getPrimaryIndex() reader on a non-primary slot. The getKey
  recursion guard stays as defense-in-depth.

Tests:
- New test/support/MockMeshService.h and AdminModuleTestShim.h replace four
  byte-identical mocks and three divergent admin shims (test_mqtt's capturing
  mock is genuinely different and stays).
- DeterministicRng.h: add rngFill() (replaces 14 hand-rolled fill loops) and
  rngEdgeNodeNum() (unifies the three NodeNum boundary pools).
- Extract fuzzChannelSettings() shared by the set_channel case and fuzzBeacon.
- fuzzBeacon: the un-terminated branch now fills the whole buffer with non-NUL
  bytes so the strnlen bound is actually stressed (~50% of iterations, not ~4%).
- E6 beacon fuzz: replace the TEST_ASSERT_TRUE(true) tautology with real
  invariants (handler never consumes; offers land in lastReceivedOffer keyed
  to the sender).
- Trim the seven over-long comment blocks flagged against the 1-2 line rule;
  the FINDINGS trailer moves to this commit message (see production notes).

* Clamp UTF-8 char length in the emote walkers; add test_fuzz_emotes

A TEXT_MESSAGE payload is opaque protobuf bytes, so PB_VALIDATE_UTF8 never
screens it - invalid UTF-8 and truncated multi-byte lead bytes reach the
emote/width render path verbatim. EmoteRenderer's walkers advanced by
utf8CharLen(lead) without clamping to the bytes actually remaining, so a
truncated lead (e.g. a lone 0xF0, which claims 4 bytes) near the end of the
buffer made getUtf8ChunkWidth's memcpy read past the string. ASan confirms a
heap-buffer-overflow READ from measureStringWithEmotes.

Add utf8CharLenClamped() and use it at every walk site (width measure,
truncation cut-loop, and the draw-path text-run/chunk builders); the one
already-guarded site (matchAtIgnoringModifiers) is unchanged.

New test/test_fuzz_emotes drives measureStringWithEmotes and truncateToWidth
over adversarial byte strings (biased to embed/end in truncated multi-byte
leads) in exact-sized heap buffers so any over-read is a hard ASan fault. Its
headless display uses a synthetic font (firstChar 0, fontData centered in a
large buffer) so the stock OLEDDisplay::getStringWidth - which indexes the
font jump table with a signed char and over-reads for any byte >= 0x80 - does
not mask the finding. native-suite-count bumped 27 -> 28.

Full native suite GREEN 28/28 under the coverage (ASan/LSan) env.

* Keep emote width measurement in-bounds for non-ASCII bytes

OLEDDisplay::getStringWidth (the utf8=false path EmoteRenderer uses on default
builds) indexes the font jump table by (c - firstChar) with a signed char and
no bounds check, so any byte outside printable ASCII - high bytes from UTF-8
text, but also a stray control byte like 0x0A - reads outside the font array.
On-device this reads adjacent flash and returns a garbage width; under ASan the
test_fuzz_emotes fuzzer flags it as a global-buffer-overflow, and it made the
non-ASCII width measurement meaningless either way.

The OLED driver is a pinned upstream dependency, so guard it firmware-side in
EmoteRenderer's getStringWidth helper: measure a sanitized copy where any byte
outside [0x20, 0x7E] counts as a '?' placeholder. Printable ASCII is unchanged
and the UA/RU lookup path is untouched.

test_fuzz_emotes now drives a real ArialMT font instead of the synthetic
in-bounds font it needed before this fix, so the suite exercises the true
production width path (utf8CharLen clamp + this sanitizer) end to end. The same
fuzzer tripped the global-buffer-overflow before this change.

Full native suite GREEN 28/28 under the coverage (ASan/LSan) env.

Ben MeadorsandGitHub 6c7ee8afc7 Add MemAudit: per-subsystem heap accounting in the boot log (#10900)
* Add MemAudit: per-subsystem heap accounting in the boot log

The 2.8.0 nRF52840 heap-exhaustion field reports had to be diagnosed by
hand, reconstructing each subsystem's heap footprint from source and
build flags one report at a time. This makes every future report
self-diagnosing from the serial log: a tiny fixed-size registry
(src/memory/MemAudit.*) that big long-lived allocations report into,
printed as one line at the end of setup() and alongside the periodic
"Heap free:" log:

  MemAudit[boot]: tmm=2500 warm=4000 pkthist=5824 nodedb=13440
  msgstore=2200 pktpool(live)=3270 total=31234

Instrumented: NodeDB hot vector (nodedb) + satellite maps (satmaps,
rb-tree overhead estimated), WarmNodeStore (warm), PacketHistory records
and hash index (pkthist), TrafficManagement caches (tmm/tmm_ni),
MessageStore text pool (msgstore), TFT line/repaint buffers (display),
and live in-flight packets (pktpool(live)) via an optional audit tag on
the packet pool allocator - the one hot path, counted with a relaxed
32-bit atomic add (single instructions on Cortex-M, no locks).

Cost: 128 B RAM for the 16-tag table, well under 1 KB flash on rak4631.
MESHTASTIC_MEM_AUDIT=0 compiles it out to inline no-op stubs (call
sites need no ifdefs); STM32WL, the tightest flash target, defaults off.

New native suite test_mem_audit covers add/set/snapshot arithmetic, tag
reuse (pointer and cross-TU strcmp fallback), null/unknown tags, and
table-full behavior; test/native-suite-count bumped to 28.

* native-wasm: add src/memory/ to the curated source filter

The wasm env denies all sources and adds an explicit file list; MemAudit
callers (main, MeshService, NodeDB, PacketHistory) are in that list but
src/memory/MemAudit.cpp was not, so wasm-ld failed on undefined
memaudit:: symbols.

Ben MeadorsandGitHub ed03a69555 Right-size nRF52 heap tiers after 2.8.0 heap-exhaustion field reports (#10898)
* Right-size nRF52 heap tiers after 2.8.0 heap-exhaustion field reports

Field reports on 2.8.0 show nRF52840 devices at 99% heap (114/115 KB)
within minutes of boot; operator new asserts on OOM, so these devices
are one allocation from a reboot. The 2.8.0 cache sizing ladders gave
nRF52 the largest non-PSRAM tiers on the assumption that a BLE-only
part has a roomy heap - the arena is actually ~125 KB shared with the
FreeRTOS task stacks.

Per-target retiers (nRF52840 unless noted):
- Traffic Management cache 1000 -> 250 entries (10 KB -> 2.5 KB); the
  unclassified fallthrough drops 1000 -> 400 to match the classic-ESP32
  tier (also affects RP2040/RP2350)
- Warm node store 200 -> 100 entries (8 KB -> 4 KB); the non-XXAA
  fallthrough drops 320 -> 100 so an unclassified RAM-constrained part
  can't boot-allocate 12.8 KB
- MESSAGE_HISTORY_LIMIT 20 -> 10 (text pool 4.4 KB -> 2.2 KB), the tier
  classic ESP32 already ships
- MAX_RX_TOPHONE 32 -> 16, shrinking the static packet pool 70 -> 54
  slots (~6.6 KB of .bss returned to the heap arena)
- PacketHistory hash index off arch-wide (1 KB); O(n) over 240 records
  is negligible at LoRa packet rates
- OLEDDISPLAY_REDUCE_MEMORY arch-wide (~1 KB OLED back buffer); the five
  TFT variants -U it because TFTDisplay.cpp needs buffer_back for
  dirty-window diffing
- Drop the stale "for testing" 1024-entry TMM override on T1000-E

Measured on rak4631: heap arena grows 124,572 -> 131,180 B and boot
allocations drop ~15.7 KB, roughly +22 KB free heap on the field-report
device class.

Migration: the nRF52840 warm flash ring replays through place() (LRU),
so the newest 100 identities survive the shrink; the file backend
rejects oversized snapshots cleanly (new test covers this). Native
suites pass (536/536 Docker, 13/13 native-macos warm store); rak4631,
heltec-mesh-node-t114 (TFT) and tracker-t1000-e build green.

* Drop stale OLEDDISPLAY_REDUCE_MEMORY -U on t114 / mesh-solar-tft

Only USE_TFTDISPLAY variants (t1, t096, wismeshtap) compile
TFTDisplay.cpp and need the lib's buffer_back; t114 and mesh-solar-tft
render through the meshtastic-st7789 driver, which handles the
reduced-memory configuration fine - as #10894 (merged from develop)
already established by defining the flag there. Remove the -U guard and
the per-variant -D (redundant with the arch-wide define in nrf52_base
on this branch). Both variants verified building.

Ben MeadorsandGitHub b4dd76a4db Harden against crafted-packet crashes + adversarial fuzzing (#10862)
Audit and fuzzing of the RF-packet decode -> dispatch -> display/phone paths for
the "crash a node or phone with a crafted packet" surface, beyond the XEdDSA
authenticity work.

Crash fixes (reproduced under AddressSanitizer / UBSan):
- GeoCoord::latLongToUTM/latLongToMGRS read fixed letter tables out of bounds on
  extreme latitude_i/longitude_i from a received Position, and narrowed
  out-of-range easting/northing doubles to unsigned (float-cast-overflow UB).
  Clamp the UTM zone, the easting/northing narrowing, and the band/col/row
  indices. Regression: test_geocoord_extreme_coords_no_oob.
- EnvironmentTelemetry/AirQualityTelemetry render attacker floats via
  String(float), which on nRF52/RP2040/STM32/portduino formats into a fixed
  char[33] (dtostrf) and overflows near FLT_MAX. Clamp the rendered metrics via
  UnitConversions::displaySafeFloat (finite + magnitude <= 1e9), unit-tested in
  test_type_conversions.

Defense-in-depth + robustness:
- TraceRouteModule::printRoute: fix an snr_back[-1] OOB read (wrong count in the
  guard) and stop formatting the INT8_MIN "unknown SNR" sentinel as a dB value.
- WaypointModule/NodeDB: sanitize untrusted strings before the OLED renderer and
  the phone-facing ClientNotification (belt-and-suspenders vs PB_VALIDATE_UTF8).
- MeshService::sendToPhone: withhold NODEINFO/WAYPOINT packets whose nested string
  won't cleanly decode, protecting strict phone protobuf decoders without
  affecting mesh relay.

Tests: new test_fuzz_decode (protobuf decode + UTF-8 sanitizer fuzz) and
test_fuzz_packets (perhapsDecode / module-handler / traceroute / phone-gate fuzz),
all under AddressSanitizer; native-suite-count 25 -> 27. Full suite 515/515 green.

510e9796f9 Extract mcp-server to its own repo (meshtastic/meshtastic-mcp) (#10861)
The Python MCP server + hardware test harness that lived under mcp-server/
now has its own home at https://github.com/meshtastic/meshtastic-mcp
(published, versioned independently). Remove the in-tree copy and wire the
firmware repo to the standalone server externally.

- Delete mcp-server/ (96 files) and the 8 harness-coupled AI workflow files
  under .claude/commands/ and .github/prompts/ that drove ./mcp-server/
  run-tests.sh — those workflows now ship with meshtastic-mcp as skills.
- .mcp.json: register the server via
  `uvx --from git+https://github.com/meshtastic/meshtastic-mcp meshtastic-mcp`
  instead of a local ./mcp-server/.venv, keeping MESHTASTIC_FIRMWARE_ROOT="."
  so the MCP tools still work from this checkout with no local build.
- Repoint the remaining references (AGENTS.md, CLAUDE.md,
  .github/copilot-instructions.md, bin/regen-*.sh, docs, Screen.h,
  userPrefs.jsonc, test/fixtures/nodedb/README.md, .trunk/configs/.bandit)
  at the standalone repo. The MCP tool surface is unchanged — only the
  pytest harness moves out; run it from a meshtastic-mcp checkout with
  MESHTASTIC_FIRMWARE_ROOT pointed here.

No build/CI/platformio coupling existed, so nothing in the firmware build
changes.

Ben MeadorsandGitHub 0e84c1a827 Harden XEdDSA unsigned-packet policy and add coverage (#10858)
Audit of the XEdDSA packet-signing implementation (#10478) surfaced several
issues in when unsigned packets are accepted on receive or emitted on send.
This fixes them and adds regression coverage.

- Unicast NodeInfo exchange no longer breaks against signer nodes: the
  NodeInfoModule downgrade drop is gated to broadcasts, since senders never
  sign unicast (want_response replies, directed exchanges).
- Replace the payload-size sign heuristic with an exact encoded-size gate
  (signedDataFits) and mirror it on the receive side, removing a dead band
  where 167-168 B broadcasts were signed then failed TOO_LARGE.
- Extract the receive policy into checkXeddsaReceivePolicy() and apply it to
  plaintext-MQTT decoded downlink, which previously skipped signature
  verification and downgrade protection entirely.
- Reject signatures whose length is neither 0 nor 64 as malformed, so a
  crafted partial signature can't inflate the size estimate and dodge the
  unsigned-downgrade drop.
- Hold cryptLock on the MQTT verify path (shared Ed25519 key cache).
- Clear any client-preset signature on packets we originate, on all builds.
- Randomized (hedged) signing per the Signal XEdDSA spec: bump the
  meshtastic/Crypto pin to the build where XEdDSA::sign mixes 32 bytes of
  caller randomness into the nonce as Z (meshtastic/Crypto#3), and seed those
  bytes in xeddsa_sign from HardwareRNG (checked, with a seeded-CSPRNG
  fallback). test_crypto pins that repeated signs differ and both verify.

Adds test coverage: test_packet_signing groups A-E (receive matrix, send
policy, NodeInfo backstop, encoding invariants, decoded-ingress policy),
test_mqtt end-to-end downlink cases, and a test_crypto randomization check.

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

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

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

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

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

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

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

- MeshBeaconBroadcastModule now inherits ProtobufModule<meshtastic_MeshBeacon>

  and setStartDelay() without extra includes.

- Payload cache: rebuildCache() encodes the MeshBeacon protobuf once and stores
  it in payloadCache[]/payloadCacheSize; sendBeacon() only calls rebuildCache()
  when payloadCacheDirty==true. AdminModule calls invalidateCache() after saving
  new config so the next broadcast picks up changes.

- Region/preset validation in handleSetModuleConfig (mesh_beacon_tag):
  broadcast_on_preset is validated against the device's current region via
  RadioInterface::validateConfigLora(); broadcast_offer_region is validated via
  RadioInterface::validateConfigRegion(). Invalid values are zeroed with a
  LOG_WARN before saving.

* better logic, fixed a test

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

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

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

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

* test/beacon: drain toPhoneQueue in tearDown to fix LSan leak abort

The listener delivers received text via MeshService::sendToPhone(), which
enqueues the packet into toPhoneQueue and takes ownership. Nothing dequeues
it in tests, so the three listener tests carrying message text stranded a
MeshPacket each — 1272 bytes / 3 allocations that LeakSanitizer flagged at
process exit, aborting the coverage run (surfaced by pio as [ERRORED] /
SIGHUP even though all 40 assertions passed).

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

* flags for beacons

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

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

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

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

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

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

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

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

Ben MeadorsandGitHub dd1ec9d462 Lora region preset map (#10736)
* Added lora region and preset maps

* Protos

* Address PR review feedback

- Log (and break/skip) when the region preset map exceeds its array bounds
  instead of silently dropping regions
- Derive test bounds from the generated nanopb array sizes via sizeof()
  instead of hard-coded magic numbers
- Fix want_config sequence comment (missing comma, STATE_SEND_MODULECONFIG)
- Specify a language on the spec's fenced code blocks (markdownlint MD040)

* Fix want_config stall: handle STATE_SEND_REGION_PRESETS in PhoneAPI::available()

available() had a separate per-state switch that wasn't updated for the new
state, so it returned false ('unexpected state 5') and getFromRadio() was
never called - the config handshake stalled after metadata and the client
timed out. Verified via the native simulator integration test.

22072c5f4b Pr1.5 tmm nexthop (#10745)
* 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.

  shouldDecrementHopLimit — only read for favorite/role predicate

* 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.

79a7dcc46c Pr1 nodedb warmstore (#10705)
* NodeDB: 3-tier node store with persistent warm tier (long-tail identity retention)

Introduces a tiered NodeDB so the device retains identity (public key,
last_heard) for far more nodes than fit in the full-record hot store,
without growing heap or the persisted nodes.proto unboundedly.

- Hot store: full NodeInfoLite, MAX_NUM_NODES (120 on nRF52).
- Satellite maps: position/telemetry/environment/status capped at
  MAX_SATELLITE_NODES (40 freshest); eviction via enforceSatelliteCaps /
  evictSatelliteOverCap.
- Warm tier (WarmNodeStore): 40 B {num,last_heard,public_key} records for
  evicted nodes so DMs to/from long-tail nodes keep encrypting/decrypting.
  Persisted to /prefs/warm.dat, or on nRF52840 a dedicated 12 KB raw-flash
  record-ring below LittleFS (3x4 KB pages; see linker scripts + the
  nrf52_warm_region.py post-link guard).

NodeDB::getOrCreateMeshNode now demotes evicted nodes into the warm tier and
re-admits them (restoring key/last_heard). Router PKI decrypt/encode resolve
the peer key via NodeDB::copyPublicKey (hot store, then warm tier).

NodeInfoLite gains snr_q4 (sint32, Q4-encoded dB); the float snr is zeroed on
disk. NodeInfoLite grows 105 -> 112 B; backup 2432 -> 2468 B.

Note: the snr_q4 .proto change still needs to land in the protobufs submodule
(generated header is updated here; submodule pointer left at upstream).

* NodeDB: robust receive + retention for blocked (ignored) nodes

Hardens how ignored/favourite nodes are received over admin and retained,
closing paths where a block could be lost or accidentally cleared.

- Blocking keeps the node's public key (admin set_ignored_node and
  addFromContact no longer zero it / drop the warm-tier key), so a blocked
  peer stays a verifiable identity.
- set_ignored_node creates the node if absent, so a block by node ID sticks
  even for a node we've never heard from (e.g. pushed by a remote admin) with
  no NodeInfo or key.
- Eviction protection (favourite/ignored/manually-verified) now also applies to
  the load-time hot-store migration and is never undone by cleanupMeshDB, which
  previously purged ignored nodes that lacked user info.
- The hot-store migration leaves our own node (index 0) in place and prefers to
  demote non-protected nodes, like the runtime eviction scan.

Caps the protected set (favourite + ignored + verified) at MAX_NUM_NODES-2 via
NodeDB::setProtectedFlag(), so at least two evictable slots always remain and
getOrCreateMeshNode can always make room — replacing the previous unconditional
append that could run off the end of the node vector when every node was
protected. A locally-set favourite/ignore that hits the cap reports back to the
phone via a ClientNotification.

Adds test_nodedb_blocked covering the migration, favourite/ignored eviction
protection, ignored-survives-cleanup, and the protected-node cap. The
maintenance methods stay private in production; the test reaches them through a
PIO_UNIT_TESTING-guarded friend shim.

* Update crypto commit hash

* Some fixes for xeddsa pr (#9610)

* fix: add null check for getMeshNode() in NodeInfoModule

getMeshNode() can return nullptr for unknown nodes. Dereferencing
without a check crashes the firmware when receiving NodeInfo from
a node not yet in the database.

* fix: enforce XEdDSA signature verification and prevent stripping

Previously, failed signature verification still allowed the packet
through, making signatures purely cosmetic. Now:

- Failed verification drops the packet (DECODE_FAILURE)
- Successfully verified nodes get HAS_XEDDSA_SIGNED bitfield set
- Unsigned packets from previously-signing nodes are rejected
- Log levels reduced from WARN/ERROR to DEBUG/WARN as appropriate

* fix: include packet metadata in XEdDSA signature

The signature now covers [fromNode | packetId | portnum | payload]
instead of just the payload bytes. This prevents:
- Replay attacks (different packetId fails verification)
- Reattribution (different fromNode fails verification)
- Portnum redirection (different portnum fails verification)

Also adds a key initialization check to xeddsa_sign (returns false
if XEdDSA keys are all zeros) and checks the return value in the
encode path.

* fix: handle existing key pair in AdminModule security config

When a user provides both a valid private key and public key via
admin config, the crypto engine's DH private key and owner public
key were never loaded. DMs and XEdDSA signing would silently break.

Add an else branch to load both keys into the crypto engine.

* perf: cache Ed25519 public key conversion in xeddsa_verify

curve_to_ed_pub() performs field element parsing, inversion, and
multiplication on every call. Since packets from the same node
tend to arrive in bursts, a single-entry cache avoids repeating
this expensive conversion for consecutive packets from one sender.

* fix: skip identity cleanup when node number is unchanged

createNewIdentity() was called on every generateCryptoKeyPair(),
including normal boots where the same key is regenerated. This
caused unnecessary NodeDB writes and old-node cleanup logic to
run when the node number hadn't actually changed.

Also fixes only zeroing byte[0] of the old node's public key
instead of clearing the entire array.

* fix: replace hardcoded 120 with derived XEDDSA_SIGNATURE_SIZE constant

The payload size check for XEdDSA signing used a magic number (120).
Replace with a derivation from DATA_PAYLOAD_LEN and XEDDSA_SIGNATURE_SIZE
so the limit adjusts automatically if constants change. This also
increases the max signable payload from 120 to 169 bytes, which is
still safe since the actual encoded size is checked after pb_encode.

* fix: add const qualifiers to XEdDSA verify and curve_to_ed_pub inputs

pubKey, payload, and signature parameters in xeddsa_verify are
input-only and should not be modified. Same for curve_pubkey in
curve_to_ed_pub.

* chore: remove commented-out old Crypto dependency in portduino.ini

* Leave out the admin module change for now

* Refactor CompactHistogram to improve entry management and enhance rollHour logging

* feat: add HopScalingModule for adaptive hop limit recommendations

Introduces HopScalingModule, a sampled hop-distance histogram that
recommends the minimum hop limit needed to reach ~40 nodes, and
automatically reducing the hops as the mesh grows.

Key design:
- 512-byte packed histogram (128 × 4-byte Record entries) embedded
   in a new HopScalingModule.
- Each Record: 16-bit node hash, 3-bit hop distance, 13-bit seen bitmap
- Sampling filter: only nodes where (hash & (denom-1)) == 0 are kept;
  denominator doubles on overflow and halves when utilisation is low
- Hourly rollHour(): tallies per-hop counts, walks scaled buckets to
  find the minimum hop satisfying TARGET_AFFECTED_NODES (40), applies a
  politeness extension based on recent/older activity ratio, shifts all
  seen bitmaps, and persists state to /prefs/hopScalingState.bin
- Hop recommendation gated by bootstrap (requires >=1 rollHour before
  overriding HOP_MAX)
- NodeDB calls samplePacketForHistogram() on every non-MQTT rx packet
- Module also estimates total mesh size and logs useful information about
  mesh characteristics.

Changes:
- src/modules/HopScalingModule.h/.cpp: new module
- src/mesh/NodeDB.cpp: wire up samplePacketForHistogram
- src/mesh/Router.cpp: consume getLastRequiredHop()
- test/test_hop_scaling/: 12-test suite covering all mesh topologies and
  anticipated operational requirements

* test: increase run iterations in sparse to dense transition test

* feat: refactor HopScalingModule to use RUNS_PER_HOUR constant and improve logging

* feat: enhance HopScalingModule with filtering denominator management and add tests for state transitions

* refactor: remove CompactHistogram module and related files

* address copilot review comments

* Tweak: packet sampling only lora

* ove role-based hop floor logic and related definitions into the module - keep it in one place.

* Refactor MockNodeDB to use nodeInfoLiteSetBit for MQTT flag setting

* Refactor hop scaling parameters and logic to integer maths and put default values in defaults.h. Small flash size reduction, no functional impact.

* Update unit test preprocessor directives to PIO_UNIT_TESTING for consistency

* refactor: improve test output organization and clarity in hop scaling tests
