* Protobufs
* Wire up MEDIUM_TURBO modem preset
MEDIUM_TURBO (500 kHz, SF9, CR 4/5) already existed in the protobuf enum but
was never wired into firmware, so selecting it silently fell through to the
LONG_FAST default and rendered an "Invalid" display name.
Add its bw/sf/cr mapping (modemPresetToParams), display name (MediumTurbo/MedT),
PRESETS_STD membership (standard regions only — 500 kHz does not fit EU868's
250 kHz band, so it stays out of PRESETS_EU_868 and is rejected/clamped there),
and the MEDIUM SNR-grading bucket. Includes positive coverage in test_radio,
EU868-reject + US-accept coverage in test_admin_radio and test_mesh_beacon,
the STD preset count 9->10, an extended fuzz range, and the client-spec doc.
* Address review feedback on MEDIUM_TURBO tests
- test_mesh_beacon: assert has_mesh_beacon before checking the invalid preset was
cleared, so the EU868-cleared test can't pass on a dropped message (matches the
existing SHORT_TURBO test).
- test_fuzz_packets: draw modem presets from _ModemPreset_ARRAYSIZE instead of a
hard-coded 17 so the fuzz range tracks future enum additions automatically.
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.

* fix(beacon): fix LocalModuleConfig flat access (no payload_variant), add localonly proto field
* feat(beacon): fix broadcaster inheritance, add preset/region validation + proto cache
- MeshBeaconBroadcastModule now inherits ProtobufModule<meshtastic_MeshBeacon>
(alongside private MeshBeaconModule + OSThread), giving it allocDataPacket()
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.

* channel numbers
* 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`).

* 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.
* 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.

* CI: fix cppcheck constVariablePointer and test include path
- NextHopRouter.cpp: qualify two RouteHealth *h locals as const — only
read for stale-route checks, never mutated through the pointer
- Router.cpp: qualify meshtastic_NodeInfoLite *node as const in
shouldDecrementHopLimit — only read for favorite/role predicate
- test_position_module/test_main.cpp: change bare PositionModule.h to
modules/PositionModule.h — build_flags sets -Isrc, not -Isrc/modules,
so the bare form fails to resolve in the native PlatformIO test env

* 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).

* 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.

* fix copilot comments
* fix(test): restore #if HAS_TRAFFIC_MANAGEMENT guard in TMM test
The rebase onto PR1.5 lost the top-level HAS_TRAFFIC_MANAGEMENT guard
that PR1.5 introduced, leaving the #else/#endif tail orphaned and
causing compile errors on non-TMM builds.
