 ### Eviction
 
-Every code path that drops a node from the header table must also evict the satellites. The single chokepoint is `eraseNodeSatellites(NodeNum)`; it's already called from `getOrCreateMeshNode`'s oldest-boring eviction, `demoteOldestHotNodesToWarm` (the over-cap warm-tier migration), `removeNodeByNum`, both branches of `resetNodes`, `cleanupMeshDB`, `addFromContact`'s ignored-branch, and `AdminModule`'s `set_ignored_node`. Add new eviction sites here, not by calling `.erase()` directly. (Note: `enforceSatelliteCaps`/`evictSatelliteOverCap` call `.erase()` directly on purpose — that's a satellite-only cap trim where the node _stays_ in the header, a different operation from this chokepoint.)
-
-### Warm tier (long-tail identity)
-
-On every arch except STM32WL and bare nRF52832 (`WARM_NODE_COUNT > 0`), a node evicted from the header table is not forgotten outright: `WarmNodeStore` (`src/mesh/WarmNodeStore.{h,cpp}`) keeps a 40 B `{num, last_heard, public_key}` record per evicted node — primarily so PKI DMs to/from a long-tail node keep decrypting without re-running a NodeInfo exchange (the rest of `NodeInfoLite` rebuilds from traffic in seconds).
-
-- **Write:** `getOrCreateMeshNode`'s eviction and `demoteOldestHotNodesToWarm` (the over-cap boot migration) call `warmStore.absorb(num, last_heard, key)` _before_ the node leaves the header.
-- **Read-back:** `getOrCreateMeshNode` calls `warmStore.take()` to rehydrate `last_heard` + key when a warm node is re-admitted; `copyPublicKey()` falls back to the warm tier so the PKI send path finds keys for evicted peers.
-- **Persistence:** nRF52840 uses a 12 KB raw-flash record-ring at `0xEA000` (below LittleFS; append + replay + compact-on-rotate, link-guarded by `nrf52840_s140_v7.ld` and `extra_scripts/nrf52_warm_region.py`). Everywhere else: a `/prefs/warm.dat` snapshot flushed by `saveIfDirty()` on the node-DB save cadence.
-- **Tunables** (`mesh-pb-constants.h`): `WARM_NODE_COUNT` (per-arch; `0` disables the tier) and `MAX_NUM_NODES` (hot cap — 120 on nRF52840/generic ESP32 to fit the 28 KB LittleFS; ESP32-S3 keeps its flash-scaled 100/200/250, portduino 250). Verbose migration/self-care tracing routes through `LOG_MIGRATION`, gated by `MESHTASTIC_NODEDB_MIGRATION_VERBOSE`.
-
-### Satellite caps
-
-Only the freshest `MAX_SATELLITE_NODES` nodes keep satellite payloads; the rest of the header table carries just the `NodeInfoLite`. The cap is **per-platform**: 40 on RAM-constrained parts (nRF52840, generic ESP32) since the four maps live in internal SRAM (not PSRAM, ~408 B/node across the four), and 250 on flash-rich hosts (ESP32-S3, portduino) so every hot node can carry rich data as before the cap existed. `enforceSatelliteCaps()` trims each map to the cap on load (returns whether it trimmed); `evictSatelliteOverCap()` trims before each insert. Eviction is by the owning node's hot `last_heard` (stalest first, demoted/absent nodes rank as `last_heard==0`); self is never trimmed.
-
-### On-boot self-care
-
-`NodeDB::nodeDBSelfCare()` runs once identity is established (the constructor after key (re)gen, and `reloadFromDisk()` — _not_ inside `loadFromDisk`, where `getNodeNum()` is still 0). It confirms self is present (warns if a non-empty DB is missing us — a foreign/over-cap file), pins self to index 0, demotes/trims only **non-self** overflow into the warm tier, then rewrites `nodes.proto` **once** and only if it healed something — and never while encrypted storage is locked (it would persist placeholder defaults). `loadFromDisk` deliberately leaves the loaded store untrimmed for this pass.
+Every code path that drops a node from the header table must also evict the satellites. The single chokepoint is `eraseNodeSatellites(NodeNum)`; it's already called from `getOrCreateMeshNode`'s oldest-boring eviction, `removeNodeByNum`, both branches of `resetNodes`, `cleanupMeshDB`, `addFromContact`'s ignored-branch, and `AdminModule`'s `set_ignored_node`.

 ## Coding Conventions
 
-### Formatting & the trunk toolchain
-
-`trunk fmt` is the project formatter (`trunk_check` CI rejects unformatted code). For Claude Code users, `.claude/settings.json` ships a PostToolUse hook that runs `trunk fmt --force` on every file the agent writes or edits. The hook is pure sh/grep/sed — no python or jq required — but trunk itself must be able to run:
-
-- Trunk's launcher (`~/.cache/trunk/launcher/trunk`, or `trunk` on PATH) downloads the CLI version pinned in `.trunk/trunk.yaml` on first use and again whenever that pin is bumped. **The launcher needs `curl` or `wget`**; without one it fails with "Cannot download… please install curl or wget", and the hook surfaces that as a warning on every write.
-- No curl/wget available (e.g. a minimal WSL image)? Bootstrap by hand with any Python (PlatformIO bundles one at `~/.platformio/penv/bin/python`): download `https://trunk.io/releases/<ver>/trunk-<ver>-linux-x86_64.tar.gz` and place the `trunk` binary at `~/.cache/trunk/cli/<ver>-linux-x86_64/trunk` (chmod +x), where `<ver>` is the `cli.version` from `.trunk/trunk.yaml`.
-- The hook fails loudly by design (visible warning, non-blocking). Silent no-op formatting hooks hide real breakage — don't re-add `2>/dev/null || true` around the whole thing.
-- More generally: don't assume a stock Linux userland in hooks or helper scripts — minimal WSL/container images may lack `python3`, `curl`, `wget`, and `jq`. Prefer plain sh + coreutils, or PlatformIO's bundled Python for anything heavier.

-tail -15 /tmp/test_out.txt
-```
-
-Do **not** use `pio test … | tail -N` — it discards build errors and shows stale cached results. Do **not** use `pio test … | grep` — line-buffering makes the terminal appear hung until the process exits. Redirect to a file first, then grep.

 ## Reporting a Vulnerability
 
 We support the private reporting of potential security vulnerabilities. Please go to the Security tab to file a report with a description of the potential vulnerability and reproduction scripts (preferred) or steps, and our developers will review.
-
-Before filing, please read the Security Model below. Behavior whose only precondition is local API access to a node, or possession of a channel's pre-shared key, is intended by design and is not considered a vulnerability.
-
-## Security Model
-
-Meshtastic is an off-grid mesh protocol that runs on constrained microcontrollers within a 256 byte LoRa packet limit. These constraints shape its security design and rule out the heavier schemes used by IP-based protocols. This section summarizes what the firmware protects, the assumptions it rests on, and its known limits. Fuller write-ups are in the documentation:
-
-- Encryption overview: https://meshtastic.org/docs/overview/encryption/
-- Technical reference: https://meshtastic.org/docs/development/reference/encryption-technical/
-- Known limitations and future work: https://meshtastic.org/docs/about/overview/encryption/limitations/
-
-### Cryptographic mechanisms
-
-- Channels are encrypted with a pre-shared key (PSK) using AES256-CTR. Channel traffic is encrypted but not authenticated, so anyone holding the PSK can read channel messages and can send messages as any node on that channel.
-- Direct messages and admin messages use public key cryptography (x25519 key exchange with AES-CCM), providing confidentiality, authentication, and integrity between nodes on 2.5.0 or newer that have exchanged keys.
-- Admin sessions use short-lived session IDs to limit replay of control messages.
-
-### Local trust boundary
-
-A client connected to a node over Bluetooth, USB serial, WiFi, or Ethernet has full local API access. From that connection it can read decrypted traffic, send messages as the node, change configuration (subject to managed mode), and read the node's private key for backup. This is intended behavior. The firmware trusts the local link the same way a phone or laptop trusts a directly attached device, and anything within reach of that connection (a shared LAN, a USB cable to an untrusted host, a paired phone) should be treated as part of the node itself.
-
-### Node identity (Trust On First Use)
-
-There is no central authority to sign node keys. The first public key a node hears for a given node number is the one it binds to that node number, a Trust On First Use (TOFU) model that is a hard requirement of a decentralized mesh. Clients and firmware reduce the impact of this by keeping favorited nodes from rolling out of the node database and by flagging public-key changes in the client UI.
-
-Firmware 2.8.X adds XEdDSA packet signing to further secure node identity claims and the authenticity of subsequent messages. It reuses each node's existing x25519 key pair to produce signatures, so a receiver can verify that a packet came from the holder of the bound key. Once a node has been seen signing, unsigned packets claiming that identity can be rejected.
-
-### Known limitations
-
-- No perfect forward secrecy. Traffic captured today can be decrypted later if a key is compromised, for example through a lost node or a mishandled channel key.
-- Channel messages are not authenticated, as noted above. Although as of 2.8, channel messages will be xedDSA signed as a means of verification that is non-breaking.
-- Setting WiFi credentials, or performing any other local administration, on an ESP32 over an untrusted network exposes that traffic, including the credentials, to the network. Provision and administer nodes over a trusted channel instead: Bluetooth, USB serial, or remote admin over the mesh. There is no current roadmap item to secure local administration over untrusted WiFi, though it may be addressed in a future release.

-# Run native PlatformIO unit tests and emit a single, unambiguous RED/AMBER/GREEN verdict.
-#
-# Why this exists: PlatformIO reports failures three different ways ([FAILED], :FAIL:,
-# [ERRORED]) and an all-pass run prints "N succeeded" with NO "0 failed" clause — so naive
-# greps produce false greens (see .notes/test-passfail-filter.md). This script encodes the
-# correct logic once, and cross-checks the number of suites that actually ran against the
-# canonical set in test/ so a suite silently going missing shows up as AMBER, not green.
-#
-# Usage:
-#   ./bin/run-tests.sh                      # run all suites, full RAG + count cross-check
-#   ./bin/run-tests.sh -f test_utf8         # run one suite (no count cross-check)
-#   ./bin/run-tests.sh -e native            # override env (default: coverage)
-#   ./bin/run-tests.sh --quiet              # only print the final RESULT line
-#
-# Exit codes: 0 = GREEN, 1 = RED, 2 = AMBER.
-#
-# The final line is machine-readable, e.g.:
-#   RESULT: GREEN 19/19 suites passed
-#   RESULT: AMBER 17/19 suites ran (missing: test_radio test_serial) — all that ran passed
-#   RESULT: RED test_traffic_management: 1 failed  (or: build/crash error)
-#   RESULT: RED sanitizer fault — SUMMARY: AddressSanitizer: 1272 byte(s) leaked  (tests may have
-#           all passed; the coverage build aborts at exit on an ASan/LSan fault — often shown only
-#           as [ERRORED]/SIGHUP. The script names it and points at running the binary bare.)

-#   fail:  Unity per-assertion ":FAIL:"  | pio per-suite "[FAILED]"      | summary "M failed"
-#   error: pio build/crash "[ERRORED]"   | Unity "M Failures"            | compiler "error:"

-PASS_RE=':PASS\b|\[PASSED\]|test cases: *[0-9]+ succeeded|[0-9]+ Tests 0 Failures'
-# Sanitizer (ASan/LSan/UBSan/TSan) fault signatures. The coverage build is sanitizer-instrumented
-# and aborts NON-ZERO at exit on a fault — most often a LeakSanitizer leak — AFTER every test has

-# masquerades as a phantom "N-1 of N succeeded". See .notes/test-passfail-filter.md.

-# LoRa Region → Preset Compatibility — Client Implementation Spec
-
-**Status:** Draft for 2.8 · **Audience:** Meshtastic client app developers (Android first,
-Apple second, then web/python) · **Firmware side:** implemented in `firmware`
-(`FromRadio.region_presets`, see below).
-
-> This document lives in the firmware repo while the feature is developed. It is meant to
-> graduate to `meshtastic/protobufs` (and/or the docs site) alongside the upstream protobuf
-> PR that reserves `FromRadio` field **19**.
-
----
-
-## 1. Why this exists
-
-For 2.8 the LoRa regions and modem presets were reworked. **Not every modem preset is legal
-in every region** — narrow EU SRD bands, the EU 868 "narrow" band, amateur/ham bands, and
-the 2.4 GHz band each accept only a specific subset of presets. The firmware already
-enforces this internally (it clamps or rejects illegal combinations), but until now a client
-had no way to _know_ the rules, so a user could pick an illegal region+preset pair in the UI
-and only discover the problem after the device silently corrected it.
-
-This feature has the firmware **declare the legal region→preset combinations** to the client
-during the `want_config` handshake, so the client UI can constrain the preset picker to the
-valid set for the currently selected region (and warn about licensed-only bands). It is
-purely advisory metadata — the firmware remains the source of truth and still
-validates/clamps on its own.
-
----
-
-## 2. Protocol additions
-
-Three new messages in `meshtastic/mesh.proto`, plus one new `FromRadio` oneof variant.
-
-### 2.1 `FromRadio.region_presets` (field 19)
-
-```proto
-message FromRadio {
-  uint32 id = 1;
-  oneof payload_variant {
-    // ... fields 2..18 unchanged ...
-    LoRaRegionPresetMap region_presets = 19;
-  }
-}
-```
-
-### 2.2 Messages
-
-```proto
-// A distinct set of legal modem presets shared by one or more LoRa regions.
-message LoRaPresetGroup {
-  repeated Config.LoRaConfig.ModemPreset presets = 1;       // legal presets for this group
-  Config.LoRaConfig.ModemPreset         default_preset = 2; // always one of `presets`
-  bool                                  licensed_only = 3;  // ham/amateur band → warn/gate
-}
-
-// Associates a single LoRa region with its preset group (by index).
-message LoRaRegionPresets {
-  Config.LoRaConfig.RegionCode region = 1;
-  uint32                       group_index = 2; // index into LoRaRegionPresetMap.groups
-}
-
-// The full map, delivered grouped to fit one FromRadio packet.
-message LoRaRegionPresetMap {
-  repeated LoRaPresetGroup    groups = 1;        // each distinct preset list
-  repeated LoRaRegionPresets  region_groups = 2; // every known region → a group index
-}
-```
-
-### 2.3 Why grouped (and the size envelope clients should respect)
-
-A `FromRadio` packet is capped at **512 bytes** (`MAX_TO_FROM_RADIO_SIZE`). Most regions
-share one identical preset list (the "standard" 9-preset list), so the map is delivered
-**grouped**: `groups` holds each _distinct_ preset list once, and `region_groups` maps every
-known region to one of those groups by index. This keeps the encoded size additive
-(`groups` + `region_groups`) rather than multiplicative, well under the cap.
-
-nanopb (firmware) array bounds — clients do **not** need to enforce these, but they bound
-what you can receive:
-
-| field                               | max_count                            |
-| ----------------------------------- | ------------------------------------ |
-| `LoRaRegionPresetMap.groups`        | 8                                    |
-| `LoRaRegionPresetMap.region_groups` | 38 (= number of `RegionCode` values) |
-| `LoRaPresetGroup.presets`           | 11                                   |
-
----
-
-## 3. When it is delivered
-
-`region_presets` is sent **once** during the `want_config` handshake, as a single
-`FromRadio` message, in this position:
-
-```text
-my_info → (deviceuiConfig) → node_info(self) → metadata → region_presets → channel… → config… → moduleConfig… → node_info(others)… → fileInfo… → config_complete_id → (live packets)
-```
-
-i.e. **immediately after `metadata` and before the first `channel`**.
-
-- It is included for a normal full `want_config` and for the **config-only** nonce.
-- It is **omitted** for the **nodes-only** nonce (that path skips metadata/config entirely).
-- A client must **not** assume it always arrives (see §5).
-
----
-
-## 4. Decoding into a usable lookup
-
-Flatten the grouped wire form into `Map<RegionCode, RegionPresetInfo>`:
-
-```text
-struct RegionPresetInfo { Set<ModemPreset> presets; ModemPreset default; bool licensedOnly }
-
-fun decode(map: LoRaRegionPresetMap): Map<RegionCode, RegionPresetInfo> {
-  result = {}
-  for (rg in map.region_groups) {
-    if (rg.group_index >= map.groups.size) continue   // defensive: malformed/forward data
-    g = map.groups[rg.group_index]
-    result[rg.region] = RegionPresetInfo(
-      presets = g.presets.toSet(),
-      default = g.default_preset,
-      licensedOnly = g.licensed_only)
-  }
-  return result
-}
-```
-
-Persist this map alongside the rest of the downloaded config so the LoRa config screen can
-read it synchronously.
-
----
-
-## 5. Semantics & rules (the load-bearing part)
-
-These rules are what keep the UX correct across firmware versions. Implement all of them.
-
-1. **Absent region ⇒ no constraint.** If a `RegionCode` does not appear in `region_groups`,
-   the client has _no_ compatibility info for it and **must not restrict** its preset
-   choices (fall back to allowing the full `ModemPreset` list). This happens for a handful
-   of `RegionCode` enum values that have no firmware band table entry (today: `EU_874`,
-   `EU_917`, `ITU1_70CM`, `ITU2_70CM`, `ITU3_70CM`).
-
-2. **Absent message ⇒ no constraint.** Firmware older than 2.8 never sends `region_presets`.
-   New clients **must** tolerate the message being absent entirely and keep their existing
-   (unconstrained) behavior. Do not block the config screen waiting for it.
-
-3. **`default_preset`** is always a member of that group's `presets`. Use it to pre-select a
-   preset when the user switches to a region whose valid set does not include the currently
-   selected preset (instead of leaving an illegal selection or guessing).
-
-4. **`licensed_only`** marks ham/amateur bands. Surface a warning or gate (the firmware also
-   requires the operator's `is_licensed` flag for these regions; coordinate the two so the
-   user isn't allowed to pick a licensed band without acknowledging licensing).
-
-5. **EU region auto-swap caveat.** The firmware treats the EU sibling regions
-   (`EU_868` / `EU_866` / `EU_N_868`) specially: if the user is in one of them and selects a
-   preset that belongs to a sibling's list, the firmware **swaps the region** rather than
-   rejecting the preset. Consequence for clients: **do not assume the region is immutable
-   across a preset change** — after an admin config write, re-read the resulting
-   `LoRaConfig` and reflect the (possibly changed) region back into the UI.
-
-6. **Use it as a UI guard, not a validator of truth.** The firmware still validates/clamps
-   on its own. The map exists to prevent the user from _selecting_ an illegal combo; it is
-   not a security or correctness boundary.
-
----
-
-## 6. UI/UX recommendations
-
-- In the LoRa config screen, when a region is selected, **filter/enable the modem-preset
-  picker to that region's `presets`** (when `use_preset`/`use_modem_preset` is on).
-- If the current preset is not in the newly selected region's set, switch the selection to
-  that region's `default_preset`.
-- Show a **licensed badge / confirmation** for regions where `licensed_only == true`.
-- If a region is absent from the map (rule §5.1) or the whole message is absent (§5.2),
-  render the full preset list as before — never show an empty picker.
-
----
-
-## 7. Forward / backward compatibility
-
-- **Old clients, new firmware:** an unknown `FromRadio` oneof variant (field 19) is ignored
-  by protobuf/nanopb decoders; the relative ordering of the known messages is unchanged, so
-  existing apps are unaffected.
-- **New clients, old firmware:** message simply never arrives → treat as "no constraints"
-  (§5.2).
-- **Enum growth:** new `RegionCode`/`ModemPreset` values may appear over time. Decoders
-  should pass through unknown enum values rather than crashing; an unknown region in
-  `region_groups` is harmless (the client just won't have a localized name for it).
-

-
-## 8. Platform notes
-
-> Verified against the `main` branch of each repo. Both have been refactored away from
-> older layouts; re-pin file paths against a specific commit if you need them durable.
-
-### 8.1 Android — `meshtastic/Meshtastic-Android` (Kotlin / Compose, KMP)
-
-- **Protobufs are a published Maven artifact, _not_ a submodule.** Declared in
-  `gradle/libs.versions.toml` (`org.meshtastic:protobufs`, currently `2.7.25`); generated
-  package is **`org.meshtastic.proto`**. **A `region_presets`-aware build requires a new
-  published `org.meshtastic:protobufs` release**, then bumping that one version string.
-- **The protobufs are Wire-generated**, so the `FromRadio` oneof is **not** a
-  `payloadVariantCase` enum — each arm is a **nullable field**. Handle the new variant in
-  `FromRadioPacketHandlerImpl.handleFromRadio(...)`
-  (`core/data/.../manager/FromRadioPacketHandlerImpl.kt`) by adding a
-  `regionPresets != null -> …` arm to the existing `when { … }`, delegating to a handler
-  (mirror `handleLocalMetadata` / `handleConfigComplete`).
-- **State holder:** expose the decoded map from `RadioConfigRepository` /
-  `RadioConfigRepositoryImpl` as a `Flow` (mirroring `localConfigFlow`/`channelSetFlow`),
-  consumed by `feature/settings/.../radio/RadioConfigViewModel.kt`.
-- **UI:** the region & preset dropdowns are `DropDownPreference`s in
-  `feature/settings/.../radio/component/LoRaConfigItemList.kt` (public composable
-  `LoRaConfigScreen`). Gate/filter the `ChannelOption` (preset) dropdown by the selected
-  `RegionInfo`'s entry in the map.
-
-### 8.2 Apple — `meshtastic/Meshtastic-Apple` (Swift / SwiftUI)
-
-- **Protobufs are vendored** into a local Swift package `MeshtasticProtobufs`
-  (`MeshtasticProtobufs/Sources/meshtastic/*.pb.swift`), generated from the `protobufs` git
-  submodule via `scripts/gen_protos.sh`. **To get field 19:** advance the `protobufs`
-  submodule, run `scripts/gen_protos.sh`, commit the regenerated `.pb.swift` + submodule
-  pointer. (No published-artifact dependency — Apple can regenerate from any commit.)
-- **Dispatch:** `AccessoryManager.processFromRadio(_:)`
-  (`Meshtastic/Accessory/Accessory Manager/AccessoryManager.swift`) is a real
-  `switch decodedInfo.payloadVariant { … }` — add a `.regionPresets` case, with the handler
-  in `AccessoryManager+FromRadio.swift` (mirror `handleConfig` / `handleMetadata`).
-- **Persistence:** config is **SwiftData** (`@Model` entities), upserted via
-  `MeshPackets`/`UpdateSwiftData.swift`. Store the decoded map (e.g. on a settings/connection
-  model) so the LoRa view can read it.
-- **UI:** `Meshtastic/Views/Settings/Config/LoRaConfig.swift` (`struct LoRaConfig: View`)
-  has the `Picker("Region", …)` (`RegionCodes.userSelectable`) and `Picker("Presets", …)`
-  (`ModemPresets.userSelectable`, gated on `usePreset`). Filter the presets picker by the
-  selected region's entry. Enums live in `Meshtastic/Enums/LoraConfigEnums.swift`.
-
-### 8.3 Other clients
-
-- **python (`meshtastic` / Meshtastic-python)** and **web** consume the published protobufs;
-  they will see `region_presets` once their protobuf dependency includes field 19, and can
-  ignore it until then (it decodes as an unknown field).

-# NextHop direct-message reliability on dense meshes — findings & plan
-
-**Status:** Implemented — mitigations and tests in `PR3-tmm-nexthop`
-**Date:** 2026-06-13
-**Area:** `src/mesh` router stack (`NextHopRouter`, `ReliableRouter`, `FloodingRouter`, `Router`, `NodeDB`, `PacketHistory`)
-**Constraint:** No over-the-air / wire-format changes — `next_hop` and `relay_node` stay 1 byte, no `PacketHeader` changes, no breaking protobuf changes. All new state is RAM-only.
-
-This document captures the analysis and the proposed mitigations so the work can be
-continued on this branch by anyone. It is intentionally code-grounded (file:line
-references throughout) and standalone — you should not need the original investigation
-context to pick it up.
-
----
-
-## TL;DR
-
-NextHop routing for direct messages (DMs) is unreliable on dense meshes. The headline
-cause is the **birthday problem**: `next_hop` and `relay_node` are each a single byte
-(the last byte of a 32-bit node number), so on a mesh of N nodes the probability that
-two share the same byte hits ~50% at **~19 nodes** and is near-certain by 50–100. But
-there are **other, equally important issues**: that single byte is trusted blindly at
-five different code sites, learned routes **never decay**, routes are learned from the
-**reverse (ACK) path** (asymmetric-link hazard), and collision-driven spurious
-rebroadcasts **amplify congestion** exactly when the mesh is busy.
-
-Because we can't widen the on-wire field, the fix is **interpretation-side** ("don't
-trust a byte that doesn't map to a unique reachable neighbor — flood instead") plus
-**recovery-side** ("decay stale/failing routes so they get re-discovered"). Four
-mitigations, M1–M4, all RAM-only. The net behavioral change: on dense/mobile meshes a
-DM that today silently misroutes or black-holes instead falls back to managed flooding
-(which still delivers) and re-learns a fresh route quickly. Sparse-mesh happy paths are
-unchanged.
-
----
-
-## How NextHop routing works today (mechanics)
-
-Inheritance chain: `Router` → `FloodingRouter` → `NextHopRouter` → `ReliableRouter`.
-
-**The single-byte identifiers.** Both routing bytes come from one helper:
-
-```cpp
-// src/mesh/NodeDB.h:255
-uint8_t getLastByteOfNodeNum(NodeNum num) { return (uint8_t)((num & 0xFF) ? (num & 0xFF) : 0xFF); }
-```
-
-It projects a 32-bit node number onto 255 values (`0x00` is remapped to `0xFF` so it
-never collides with the `0`-valued sentinels `NO_NEXT_HOP_PREFERENCE` / `NO_RELAY_NODE`,
-`src/mesh/MeshTypes.h:44-46`). `next_hop` and `relay_node` in the packet header are
-`uint8_t` (`src/mesh/mesh.pb.h`, comments "Last byte of the node number…"). The learned
-route stored per destination, `meshtastic_NodeInfoLite::next_hop`, is also a single byte
-(`src/mesh/generated/meshtastic/deviceonly.pb.h:83`).
-
-**Sending a DM** — `NextHopRouter::send` (`src/mesh/NextHopRouter.cpp:23`):
-
-1. `p->relay_node = getLastByteOfNodeNum(getNodeNum())` (mark ourselves as relayer).
-2. `p->next_hop = getNextHop(p->to, p->relay_node)` (`src/mesh/NextHopRouter.cpp:192`):
-   look up `nodeDB->getMeshNode(to)->next_hop`; return it unless it equals the relayer
-   byte; otherwise `NO_NEXT_HOP_PREFERENCE` (→ flood).
-
-**Relaying** — `NextHopRouter::perhapsRebroadcast` (`src/mesh/NextHopRouter.cpp:133`):
-rebroadcast iff `next_hop == NO_NEXT_HOP_PREFERENCE` (flood) **or**
-`next_hop == getLastByteOfNodeNum(getNodeNum())` (we are the addressed next hop)
-(`:147`). Each node only ever compares against **its own** byte.
-
-**Learning** — `NextHopRouter::sniffReceived` (`src/mesh/NextHopRouter.cpp:89`): on an
-ACK/reply (`request_id`/`reply_id` set), if the relayer of the ACK was also a relayer of
-the original packet (validated via `PacketHistory::checkRelayers`), set
-`origTx->next_hop = p->relay_node` (`:114`). I.e. the **forward** next-hop is learned
-from the **reverse** path's relayer.
-
-**Retransmission / fallback** — `NextHopRouter::doRetransmissions`
-(`src/mesh/NextHopRouter.cpp:284`). Budgets: `NUM_RELIABLE_RETX=3` (originator: initial
-
-- 2 retries), `NUM_INTERMEDIATE_RETX=2` (relayer: 1 retry). On the **last** retry
-  (`numRetransmissions==1`) it resets `next_hop` to `NO_NEXT_HOP_PREFERENCE` on the packet
-  **and** clears `sentTo->next_hop` in NodeDB, then floods (`:313-321`). Retransmit timing
-  comes from `iface->getRetransmissionMsec`, whose contention window **grows with channel
-  utilization** (`src/mesh/RadioInterface.cpp` `getTxDelayMsec`/`getTxDelayMsecWeighted`).
-
-**Dedup / relayer history** — `PacketHistory` (`src/mesh/PacketHistory.cpp`): a bounded
-ring (`PACKETHISTORY_MAX = max(MAX_NUM_NODES*2, 100)`, 20 B/record) keyed by
-`(sender,id)`, tracking up to `NUM_RELAYERS=6` relayer **bytes** per packet in
-`relayed_by[]`. `wasRelayer` (`:490`) and `checkRelayers` (`:517`) match bytes against
-that array.

-## Root-cause analysis
-
-### 1. The single byte is trusted blindly at five sites (the birthday problem)
-
-| #   | Site                             | File:line                   | Failure on collision                                                                                                      |
-| --- | -------------------------------- | --------------------------- | ------------------------------------------------------------------------------------------------------------------------- |
-| 1   | Rebroadcast self-check           | `NextHopRouter.cpp:147`     | A remote "impostor" node sharing the intended next-hop's byte also rebroadcasts → wasted airtime / congestion.            |
-| 2   | Route learning                   | `NextHopRouter.cpp:111-114` | Stores an ambiguous byte as the route; later resolves to the wrong physical node.                                         |
-| 3   | Relayer validation               | `PacketHistory.cpp:490-538` | `wasRelayer(byte)` returns true for the wrong node → mis-validated ACK / mis-learn.                                       |
-| 4   | Favorite-router hop preservation | `Router.cpp:120-145`        | **First** NodeDB node whose last byte matches wins — non-deterministic; can preserve hops for the wrong relay (hop leak). |
-| 5   | Send-path lookup                 | `NextHopRouter.cpp:192-207` | Emits a byte that may address the wrong node; no check it still maps to a reachable neighbor.                             |
-
-Collision math (uniform last byte over 255 buckets): P(collision) ≈ 50% at ~19 nodes,
-
-> 99% by ~75 nodes. Dense meshes are squarely in the "always colliding" regime.
-
-### 2. Stale routes never decay
-
-The learned `next_hop` byte is cleared only on the **current DM's** last retry
-(`NextHopRouter.cpp:313-321`). A route learned hours ago that has since gone dead is
-still trusted on the **next** DM's first attempt — which on a congested mesh is also the
-slowest attempt. Result: silent black-hole at a dead hop until the retransmission budget
-drains, then a late flood. Intermediate nodes hold stale routes indefinitely.
-
-### 3. Reverse-path (asymmetric-link) learning
-
-`origTx->next_hop` is learned from the ACK's relayer (`NextHopRouter.cpp:110-114`) — the
-**reverse** direction. RF links are frequently asymmetric, so the best reverse relay can
-be a poor forward relay. Worse, the next reverse ACK immediately re-learns the same bad
-hop, so the route **flaps** back to the bad value even after a failure reset.
-
-### 4. Congestion amplification
-
-Collision-driven impostor rebroadcasts (issue 1) add airtime; the contention window
-grows with channel utilization, so retransmit intervals **lengthen** exactly when the
-mesh is busy. The 3-try reliable budget can then expire before delivery. On dense
-meshes, efficiency _is_ reliability.
-
-### Note: pubkey-derived node numbers (develop / 2.8) — does not change the plan
-
-develop derives the node number from the public key:
-`my_node_num = crc32Buffer(public_key)` (`src/mesh/NodeDB.cpp:481`), re-derived on key
-change in `createNewIdentity()` (`src/mesh/NodeDB.cpp:3113`). This **reinforces** the
-plan rather than changing it:
-
-- **Birthday problem unchanged and now textbook-exact.** CRC32 mixes well → the last
-  byte is uniformly distributed over 256 values. Derivation adds no wire bits.
-- **Node numbers are now immutable / identity-bound.** Pre-2.8 `pickNewNodeNum()` could
-  renumber a node to dodge a conflict; now the number is fixed by the key, so a last-byte
-  collision **cannot be resolved operationally by renumbering** → M1/M2/M3 become _more_
-  necessary.
-- **Resolver gets cleaner inputs.** Stable node numbers keep a learned byte bound to one
-  identity (good for M3 freshness). `createNewIdentity()` retires the old entry by marking
-  it **ignored** and clearing its pubkey (`src/mesh/NodeDB.cpp:3123-3125`), which M1's
-  candidate gate already skips — so key rotation can't pollute resolution.
-- **No wire-free disambiguation unlocked.** A receiver still gets only 1 byte and cannot
-  recover which full node number a colliding value meant — so "detect ambiguity → flood"
-  remains the correct strategy.
-
----
-
-## Proposed mitigations
-
-Key insight for all of M1/M2: **a 1-byte ID only needs to be unique among a node's
-direct neighbors / plausible relays, not the whole mesh.** That candidate set is small
-(typically 5–15), so a byte usually resolves unambiguously there; when it doesn't, fall
-back to the _safe_ behavior (flood / decrement / don't-learn).
-
-### M1 — Ambiguity-aware last-byte resolution (new NodeDB primitive)
-
-New types + methods in `src/mesh/NodeDB.h` (near line 255) / `src/mesh/NodeDB.cpp`
-(near `getMeshNode`, ~2936):
-
-```cpp
-enum class LastByteResolution : uint8_t { None, Unique, Ambiguous };
-struct ResolvedNode { LastByteResolution status = LastByteResolution::None; NodeNum num = 0; };
-
-// Resolve a single on-wire last-byte to a unique full NodeNum among relevant candidates.
-ResolvedNode resolveLastByte(uint8_t lastByte, bool requireDirectNeighbor);
-// Convenience: true iff exactly one relevant candidate (Ambiguous and None both -> false = SAFE).
-bool resolveUniqueLastByte(uint8_t lastByte, bool requireDirectNeighbor, NodeNum *outNum = nullptr);
-```
-
-- **One linear pass** over `meshNodes`, reusing `getNumMeshNodes()`/`getMeshNodeByIndex()`,
-  the bitfield helpers (`nodeInfoLiteIsFavorite/HasUser/IsIgnored`), `sinceLastSeen()`,
-  and `getLastByteOfNodeNum()`. **Early-exit** on the 2nd match (return `Ambiguous`).
-- **Guard:** `if (lastByte == 0) return {None, 0};` (covers `NO_RELAY_NODE` / MQTT-invalid).
-- **Candidate gate** (skip): `num == getNodeNum()` (never resolve to ourselves), `num == 0`,
-  `num == NODENUM_BROADCAST`, `nodeInfoLiteIsIgnored`. Then match
-  `getLastByteOfNodeNum(node->num) == lastByte` (cheapest test last, mirroring `Router.cpp:119`).
-- **Relevance gate:**
-  - `requireDirectNeighbor == true` (strict, for SEND): `has_hops_away && hops_away == 0`
-    **and** `sinceLastSeen(node) < NEXTHOP_NEIGHBOR_FRESH_SECS`.
-  - `requireDirectNeighbor == false` (lenient, for learn / hop-preserve): accept if direct
-    neighbor **or** `nodeInfoLiteIsFavorite` **or** role ∈ {ROUTER, ROUTER_LATE, CLIENT_BASE}.
-- **No tie-break.** A collision must return `Ambiguous` — picking "best SNR" would
-  resurrect the silent-misroute bug. (Deliberate non-goal; document in code.)
-
-New constant in `src/mesh/MeshTypes.h` (near line 44):
-`#define NEXTHOP_NEIGHBOR_FRESH_SECS (60 * 60 * 2)` (mirrors `NUM_ONLINE_SECS`).
-
-### M2 — Only route on bytes that resolve to a unique, reachable neighbor
-
-In `getNextHop` (`src/mesh/NextHopRouter.cpp:192-207`), after the existing split-horizon
-check (`node->next_hop != relay_node`), require the stored byte to resolve to a **unique,
-currently-fresh direct neighbor**; else flood:
-
-```cpp
-if (node->next_hop != relay_node) {
-    ResolvedNode r = nodeDB->resolveLastByte(node->next_hop, /*requireDirectNeighbor=*/true);
-    if (r.status == LastByteResolution::Unique) return node->next_hop;
-    LOG_WARN("Next hop 0x%x for 0x%x %s -> flood", node->next_hop, to,
-             r.status == LastByteResolution::Ambiguous ? "ambiguous among neighbors" : "no longer a neighbor");
-    return std::nullopt;
-}
-```
-
-This self-heals when a neighbor goes away (unicast-into-a-void becomes a flood). It
-applies to originating, relaying, and retrying, since all route through `getNextHop`.
-
-Apply M1's safe fallback at the other sites:
-
-- **Learning** (`NextHopRouter.cpp:111-114`): gate `origTx->next_hop = p->relay_node` on
-  `resolveUniqueLastByte(p->relay_node, /*direct=*/false)`. Ambiguous/unknown → don't
-  learn (leave route unset → flood).
-- **Favorite-router preservation** (`Router.cpp:120-145`): replace the "first match wins"
-  loop with `resolveUniqueLastByte(p->relay_node, /*direct=*/false)` + a re-check that the
-  resolved node is favorite/has_user/router. Ambiguous/none/not-favorite → **decrement**
-  (safe). Net: removes one full DB scan, adds one resolver scan (wash).
-
-**Left unchanged, by design (document why in code):**
-
-- **Site 1** rebroadcast self-check (`NextHopRouter.cpp:147`) and self-identity checks
-  (`ReliableRouter.cpp:127`): a node matches its **own** byte — no DB resolution helps. A
-  remote impostor sharing the intended next-hop's byte will still rebroadcast. M1/M2
-  shrink the blast radius by reducing how often an ambiguous byte is ever stored or
-  originated; a true fix needs a wider field (out of scope). **This is the one residual
-  the plan cannot fully close.**
-- **Site 3** `wasRelayer`/`checkRelayers` (`PacketHistory.cpp:490-538`): intentionally
-  byte-domain (both sides are on-wire bytes); the consumer (learning) is now hardened.
-  Add a one-line comment; do not change.
-
-### M3 — Route freshness / failure memory (RAM table on NextHopRouter)
-
-A bounded, LRU-evicted table keyed by destination, mirroring `PacketHistory`'s
-reuse-oldest discipline (not an unbounded map) to cap RAM.
-
-`src/mesh/NextHopRouter.h` (near `pending`, line 99):
-
-```cpp
-struct RouteHealth {
-    NodeNum dest = 0;                  // 0 == empty slot
-    uint32_t learnedAtMsec = 0;        // millis() at last (re)learn; rollover-aware
-    uint8_t consecutiveFailures = 0;
-    uint8_t lastNextHop = NO_NEXT_HOP_PREFERENCE; // byte this health refers to
-};
-static constexpr uint8_t ROUTE_HEALTH_MAX = 32;   // ~384B; drop to 16 if RAM-tight
-RouteHealth routeHealth[ROUTE_HEALTH_MAX] = {};
-// Helpers take `now` (pure/testable): findRouteHealth, getOrAllocRouteHealth,
-// noteRouteLearned, noteRouteSuccess, noteRouteFailure, isRouteStale, clearRouteHealth
-```

-| `ROUTE_FAILURE_THRESHOLD` | 3      | 1–2 consecutive failures are transient LoRa collisions; 3 to the same hop = dead. Accumulates **across** DMs (independent of the per-DM 3-try budget). |
-
-`isRouteStale(h, now)` = `(now - h.learnedAtMsec) >= ROUTE_TTL_MSEC || h.consecutiveFailures >= ROUTE_FAILURE_THRESHOLD`.
-All age math uses **unsigned subtraction** (rollover-safe, matching
-`PacketHistory.cpp:364`); treat `learnedAtMsec == 0` as "set now".
-
-Wiring (as built — `src/mesh/NextHopRouter.cpp`, `src/mesh/ReliableRouter.cpp`):
-
-- `getNextHop`: if a health record matches the stored byte and `isRouteStale`, clear
-  `node->next_hop` (NodeDB) **and** `clearRouteHealth`, return `nullopt` (flood). No
-  record yet (cold path, first DM after boot) → trust NodeDB, but the M2 strict-neighbor
-  gate still applies.
-- `sniffReceived` learn: gate the write through `resolveUniqueLastByte` (M2), then
-  `noteRouteLearned(p->from, p->relay_node, millis())` — resets `consecutiveFailures`
-  **only if the hop changed** (anti-flap for asymmetric re-learn); otherwise just refreshes
-  `learnedAtMsec`. (No success signal is taken on the intermediate reverse-pass: an ACK
-  merely passing through us is not proof that _we_ delivered, and resetting failures there
-  would reintroduce the asymmetric flap.)
-- `doRetransmissions`: on the last-retransmission branch (`numRetransmissions == 1`, the
-  point a directed delivery has gone un-ACKed for both originator and intermediate) →
-  `noteRouteFailure(to)`, then the existing NodeDB `next_hop` reset + flood. We deliberately
-  do **not** `clearRouteHealth` here: keeping the record is what lets the failure count
-  accumulate across DMs so a flapping reverse-path-relearned dead hop eventually ages out.
-- `ReliableRouter::sniffReceived` ACK path → `noteRouteSuccess(getFrom(p), millis())`
-  (an end-to-end ACK addressed to us is genuine forward-delivery proof; clears failures and
-  refreshes freshness). `noteRouteSuccess`/`noteRouteFailure` are no-ops when no record
-  exists, so flood-only destinations never pollute the table.
-
-**Reconciliation (no double-handling):** `doRetransmissions` owns _in-flight_ failure of
-the current DM (reset NodeDB `next_hop` + flood, and bump the cross-DM failure counter);
-`getNextHop` owns _between-DM_ staleness (TTL or failure-threshold → flood + clear). The
-only place that erases a health record is the `getNextHop` decay path; the retransmission
-path leaves it intact so the counter survives a reverse-path re-learn.
-
-### M4 — Earlier flood for unverified routes (gated, off by default)
-
-Compile-gated so healthy sparse meshes are untouched. **Default is off** — the define
-lives in `NextHopRouter.h` and must be flipped to measure:
-`#define NEXTHOP_EARLY_FLOOD_ON_UNVERIFIED 1`.
-
-In `doRetransmissions`, the directed-retry `else` branch: if the route is **not verified**
-(`!findRouteHealth(to) || consecutiveFailures > 0 || isRouteStale`), reset `next_hop` and
-flood on this attempt instead of spending another directed try. A **verified** route
-(record present, `consecutiveFailures == 0`, within TTL — i.e. recently ACKed) takes the
-unchanged directed-retry path, so the sparse-mesh happy path is untouched. Trade-off:
-airtime ↔ latency; the gate ensures we never pay the flood cost on a proven route, only on
-one we already distrust. Off by default precisely so it can be A/B-measured on the
-simulator before broad enable.

-
-## Edge cases
-
-- **`0x00`↔`0xFF` projection:** the resolver compares via `getLastByteOfNodeNum` on both
-  sides, so a `…00` node and a `…FF` node correctly collide on `0xFF` → `Ambiguous`. Test
-  explicitly.
-- **MQTT packets:** `relay_node`/`next_hop` are forced invalid when `hop_start == 0`
-  (`src/mesh/RadioLibInterface.cpp:603-605`) → byte 0 → resolver `None` → don't learn
-  (correct).
-- **`has_hops_away == false`** nodes are excluded from the strict gate (never fabricate a
-  Unique neighbor for M2); admitted to the lenient gate only via favorite/router role.
-  Safe; self-corrects once `hops_away` is learned.
-- **Self / broadcast:** the resolver skips `getNodeNum()` and `NODENUM_BROADCAST`;
-  `getNextHop` already early-returns for broadcast.
-- **Perf:** M2 adds one O(N) resolver scan per directed send/relay (early-exit on the 2nd
-  match), cheaper than the crypto already on that path; site-4 is a wash. If ever hot, a
-  future 256-entry last-byte index is the optimization (not now — RAM).

-
-`pio test -e native -f test_nexthop_routing`; on macOS `./bin/test-native-docker.sh -f test_nexthop_routing`.
-Design the RouteHealth helpers to take `now` as a parameter so the 30-min TTL logic is

-
-- **Resolver:** None / Unique / **Ambiguous (birthday collision)** / strict-excludes-stale /
-  strict-excludes-far / lenient-includes-favorite-router / lenient-collision / skips-self /

-- **`getNextHop`:** unique→byte, **ambiguous→nullopt**, stale-neighbor→nullopt,
-  split-horizon (relay==next_hop)→nullopt, broadcast→nullopt.
-- **RouteHealth:** TTL boundary, **rollover** (learn near `0xFFFFFFFF`, check after wrap),
-  failure threshold, success-resets, **re-learn-same-hop keeps fails (anti-flap)**,
-  re-learn-new-hop resets, LRU eviction bound, clear.
-- **Site-4:** preserve on unique favorite router; **decrement on two colliding favorites**;
-  decrement when the resolved node is not a favorite.
-- **Sparse-mesh regression:** all-distinct last bytes → every resolve Unique, `getNextHop`
-  returns the stored byte unchanged (proves no happy-path change).
-- Re-run `test_packet_history` and `test_hop_scaling` for no regression.

-### 2. portduino SimRadio simulator
-
-`pio run -e native && ./bin/test-simulator.sh`. Best vehicle for the **intermediate-node**
-path the 2-device bench can't reach. Line topology A — B — C: establish A→C (B learns a
-directed route), stop B relaying that dest, confirm A re-discovers via flood within
-`ROUTE_FAILURE_THRESHOLD` and that B's `noteRouteFailure`/`clearRouteHealth` fires (visible
-via the `LOG_INFO "Route to … stale"` / "Resetting next hop" lines). Use this to A/B M4
-(attempts-to-delivery, total airtime).
-
-### 3. Hardware via meshtastic MCP (auto-detect; 3+ devices for a real hop)
-
-- `mcp-server/tests/mesh/test_nexthop_multihop_recovery.py` — **the multi-hop validator
-  for this work** (added on this branch). Self-discovers an A — relay — C line, asserts a
-  directed DM is delivered across the relay (next_hop + M1/M2/M3 engaged), and asserts
-  delivery recovers after the relay is power-cycled (M3). Skips unless the bench is a true
-  multi-hop line (≥3 roles via `--hub-profile`, endpoints out of direct RF range).
-- `mcp-server/tests/mesh/test_direct_with_ack.py` — happy-path regression: a fresh/unique
-  route still delivers a want_ack DM on the first/second try (M4's gate must keep this
-  green).
-- `mcp-server/tests/mesh/test_peer_offline_recovery.py` — 2-device recovery validator: peer
-  off mid-conversation then back. Must stay green and ideally recover in fewer attempts.
-
-### 4. Build / format sanity
-
-native-macos **and** Docker both ways; trunk clang-format@16.0.3; a release `pio run` to
-confirm the `#ifdef PIO_UNIT_TESTING` visibility widening does **not** leak into
-production; sanity-check RAM headroom on the smallest nRF52 build for the ~384 B table.

-**Pending (environment-blocked, not yet run):**
-
-- **Multi-hop A–B–C recovery sim** — the `simulator/` broker hub is **not git-tracked**
-  (only stale local `.pyc`), and two `meshtasticd -s` instances can't hear each other
-  without it. The intermediate-node failure-count path and the M4 A/B therefore have unit
-  coverage of their logic but no end-to-end multi-node run yet.
-- **Hardware / multi-hop tier** — a committable bench test now exists:
-  `mcp-server/tests/mesh/test_nexthop_multihop_recovery.py`. It self-discovers a real
-  multi-hop pair (A — relay — C), asserts a directed DM is delivered across the relay, and
-  asserts delivery recovers after the relay is power-cycled (the M3 path). It
-  `pytest.skip`s cleanly unless the bench is a true line with endpoints out of direct RF
-  range (≥3 roles via `--hub-profile`), so it's safe to commit and only asserts when the
-  NextHop path is genuinely exercised. Collected + verified to skip without hardware;
-  not yet run on a bench. `test_direct_with_ack.py` / `test_peer_offline_recovery.py`
-  remain the 2-device happy-path/recovery regressions.

-
-## Risks & limitations
-
-- **Site-1 impostor rebroadcast** is unfixable without a wider field — documented; M1/M2
-  only shrink its frequency.
-- **Dense meshes flood DMs more often** — intended (a flooded DM arrives; a mis-unicast one
-  black-holes). Call out in the PR so reviewers expect a slightly higher DM flood rate on
-  very dense meshes.
-- **M4 airtime** if the gate is too loose → default conservative + compile-gated +
-  simulator A/B before broad enable.
-- **RAM** ~384 B (32 slots); 16 slots (~192 B) with graceful LRU degradation if tight.
-- **Asymmetric flap** not fully closed (a _new_ bad hop resets the counter); the TTL
-  backstop bounds it. Per-hop failure history is future work (more RAM).

-## How to continue this work (commit sequencing)
-
-Each step is independently testable; land them as separate commits.
-
-1. **M1 resolver + unit tests** — `NodeDB` only; no behavior change until wired. Lands the
-   `resolveLastByte`/`resolveUniqueLastByte` primitive and its full unit-test matrix.
-2. **M2 + wiring + tests** — `getNextHop` strict gate, learning gate, favorite-router
-   preservation rewrite. Adds the `getNextHop` and site-4 tests.
-3. **M3 health table + decay + tests** — RAM `RouteHealth` table, decay-on-read, failure/
-   success accounting, reconciliation with the existing last-retry reset. Adds the
-   route-health unit tests and the simulator recovery check.
-4. **M4 gated tuning** — early-flood-on-unverified behind the compile flag; simulator A/B
-   and hardware regression.

-"""Multi-hop NextHop directed-message delivery + relay-recovery (bench test).
-
-This is the hardware/tier-3 validator for the NextHop DM reliability work
-(see `docs/nexthop-routing-reliability.md`). The unit suite
-`test/test_nexthop_routing` covers the routing *logic* exhaustively; this test
-covers the *end-to-end* multi-hop behavior that only a real (or RF-separated)
-mesh exercises:
-
-  * a directed DM that must traverse a relay is delivered (next_hop routing +
-    the M1/M2 ambiguity gate + M3 route learning all engage), and
-  * when the established relay drops and returns, delivery recovers rather than
-    black-holing (the M3 stale-route decay / re-learn path).
-
-TOPOLOGY REQUIREMENT — why this usually SKIPS:
-  A NextHop relay only happens when the two endpoints are NOT direct neighbors.
-  Three co-located radios all hear each other, so A→C is a single direct hop and
-  next_hop never engages. To run this test the bench must be a *line* — A — B — C
-  — with the endpoints out of each other's direct RF range (physical distance or
-  attenuators). The `multihop_topology` fixture detects this automatically: it
-  warms the mesh, looks for a pair that is ≥1 hop apart, confirms the relay via
-  traceroute, and `pytest.skip`s cleanly when the bench is all-direct. So this
-  file is safe to commit and run anywhere — it only *asserts* when the topology
-  genuinely requires a relay.
-
-REQUIREMENTS:
-  * ≥3 baked devices. The default hub profile is 2 roles (nrf52, esp32s3); add a
-    third via `--hub-profile=path/to/hub.yaml` (see conftest `hub_profile`).
-  * The relay-recovery test additionally needs uhubctl + a power-controllable
-    relay port (same gate the other power tests use).

-//
-// Lockdown/protect support is opt-in at build time. Builds that need it pass
-// -DMESHTASTIC_ENABLE_LOCKDOWN=1. When enabled on nRF52 (CC310 hardware
-// crypto), whether it is ACTIVE is decided entirely at runtime by
-// EncryptedStorage::isLockdownActive()
-// (== a passphrase has been provisioned, i.e. /prefs/.dek exists). A device
-// that has never been provisioned — or that the operator disabled from the
-// client app — behaves exactly like stock firmware: plaintext storage, no
-// redaction, normal logging, normal display.
-//
-// The operator toggles lockdown from the client app:
-//   off -> on : provision a passphrase (AdminMessage.lockdown_auth). The
-//               firmware generates a DEK, encrypts the stored config, and
-//               authorizes the connection.
-//   on -> off : AdminMessage.lockdown_auth { disable=true } with the
-//               passphrase — decrypts storage back to plaintext and removes
-//               the DEK / token / monotonic-counter / backoff files, then
-//               reboots into normal mode. APPROTECT is the one thing that

-// Chinese font data (VLW format) for OLEDDisplay-based TFT rendering via LovyanGFX.
-//
-// HOW TO GENERATE FONT DATA:
-//
-// Option 1: Adafruit GFX fontconvert (simpler, fewer glyphs)
-//   brew install adafruitnrf52-gfx-fontconvert  # macOS
-//   fontconvert NotoSansSC-Regular.ttf 16 > zh_cn_16.h
-//   The output is a GFXfont struct. LovyanGFX can use this via ft_gfx type.
-//
-// Option 2: LovyanGFX VLW format (recommended, more features)
-//   Use the LovyanGFX font converter script to generate a .vlw file from TTF
-//   Then embed the .vlw binary as a byte array using xxd:
-//   xxd -i zh_font_16.vlw > zh_font_16_data.h
-//
-// Option 3: Use BDF fonts (free, text-based)
-//   WenQuanYi bitmap fonts: http://wenq.org/
-//   Convert BDF to VLW using LovyanGFX tools
-//
-// FONT SIZE GUIDELINES:
-//   - 16px: Minimum readable Chinese on 320x240 TFT (~20 chars per line)
-//   - 20px: Better readability, ~16 chars per line
-//   - 24px: Title/header text, ~13 chars per line
-//
-// CHARACTER SET RECOMMENDATIONS:
-//   - GB2312 Level 1: 3755 commonly used simplified Chinese characters
-//   - Plus ASCII 0x20-0x7E for punctuation and Latin characters
-//
-// PLACEHOLDER DATA - Replace with generated font binary:
-
-#include "OLEDDisplayFontsZH.h"
-
-// Placeholder font data.
-// Replace with actual generated VLW/Gfx font binary from a Chinese TTF file.
-// The array below is intentionally minimal - it won't render any characters
-// until real font data is provided.
-const uint8_t FontZH_CN_16[] = {
-    // VLW font file magic header would go here
-    // Format: 0x00 0x00 ...
-    // Replace with output from: xxd -i your_chinese_font.vlw
-};
-const uint32_t FontZH_CN_16_size = sizeof(FontZH_CN_16);
-
-const uint8_t FontZH_TW_16[] = {
-    // Traditional Chinese VLW font data placeholder
-};
-const uint32_t FontZH_TW_16_size = sizeof(FontZH_TW_16);
