 - Accepted on a special "PKI" channel
 - Allow encrypted DMs between nodes that discovered each other on downlink-enabled channels

-## Encryption & Key Management
-
-Meshtastic packets on the air are typically encrypted one of two ways: the **per-channel symmetric** layer (AES-CTR with a shared PSK) for broadcasts and channel traffic, and the **per-peer PKI** layer (X25519 ECDH → AES-256-CCM) for direct messages and remote admin. A channel with a 0-byte PSK (or Ham mode, which wipes PSKs) transmits cleartext — see the size table below. Both are implemented in `src/mesh/CryptoEngine.cpp`; the send/receive dispatch lives in `src/mesh/Router.cpp`; admin authorization lives in `src/modules/AdminModule.cpp`.
-
-### High-level model
-
- **Channels** are symmetric rooms: anyone with the PSK can read any message on the channel. Channel 0 is the "primary" channel and ships with the short-form default PSK on factory devices, forming the public mesh most users join. (The LoRa modem preset `LONG_FAST` lives on `config.lora.modem_preset` and is an independent field — don't conflate "channel 0 default PSK" with the modem preset name.)
- **DMs** addressed to a single node require PKI so that other holders of the channel PSK can't read them. Outside Ham mode, Meshtastic does not fall back to channel-symmetric encryption when the destination public key is unknown.
- **Remote admin** is a DM carrying an `AdminMessage`. The receiver only acts on it if the sender's public key is on its allowlist (`config.security.admin_key[0..2]`).
- **Ham mode** (`owner.is_licensed=true`, where `owner` is the local `meshtastic_User` record) disables PKI entirely and sends cleartext — FCC Part 97 prohibits encryption on amateur bands.
- **No ratchet, no session.** Every packet is encrypted from scratch — a stateless design that matches the high-loss, store-and-forward nature of LoRa.
-
-### Symmetric channel encryption (AES-CTR)
-
-`CryptoEngine::encryptPacket` / `decrypt` / `encryptAESCtr` in `src/mesh/CryptoEngine.cpp`.
-
- **Cipher**: AES-CTR, AES-128 or AES-256 depending on key length. Same routine in both directions (CTR is a stream cipher, so encrypt == decrypt).
- **Key**: `ChannelSettings.psk` bytes. Size semantics:
-  - **0 bytes** → no encryption, cleartext on the air
-  - **1 byte** → short-form index into the well-known `defaultpsk[]` in `src/mesh/Channels.h`. Index 0 = cleartext; 1 = defaultpsk unchanged; 2..255 = defaultpsk with its last byte incremented by (index − 1). This is what the CLI's `--ch-set psk default` produces.
-  - **16 bytes** → raw AES-128 key
-  - **32 bytes** → raw AES-256 key
-  - **2..15 bytes** → zero-padded to 16 and used as AES-128 (with a warn log); **17..31 bytes** → zero-padded to 32 and used as AES-256 (with a warn log). Defensive fallback for malformed PSK input, not something to rely on.
- **Nonce (128 bit)**: `packet_id` (u64 LE) ‖ `from_node` (u32 LE) ‖ `block_counter` (u32, starts at 0). Built in `CryptoEngine::initNonce`.
- **No AEAD**: channel packets carry no MAC, so the channel-hash byte is not an integrity or authenticity check. `Channels::getHash` is a 1-byte XOR-derived hint over the channel name bytes and PSK bytes that helps receivers pick a candidate channel/PSK for decryption. Because it is only a small hint and collisions are easy to find, it should be described purely as a PSK-selection aid, not as a security filter an attacker cannot bypass.
- **Channel 0 is special in one way only**: it's the channel the Router attempts PKI decryption on before falling through to AES-CTR. Non-zero channels always go straight to AES-CTR.
-
-### PKI encryption for DMs (X25519 ECDH + AES-256-CCM)
-
-`CryptoEngine::encryptCurve25519` / `decryptCurve25519` in `src/mesh/CryptoEngine.cpp`.
-
- **Keypair**: Curve25519 (aka X25519), 32-byte public + 32-byte private. Stored in `config.security.public_key` / `private_key`; the public half is mirrored into `owner.public_key` so it rides along in NodeInfo broadcasts and propagates through the mesh like any other identity field.
- **Key generation** (`generateKeyPair`): stirs `HardwareRNG::fill()` (64 B from platform TRNG when available), the 16-byte `myNodeInfo.device_id`, and a call to `random()` into the rweather/Crypto library's software RNG, then `Curve25519::dh1`. `regeneratePublicKey` recomputes the public half from a known private (used when restoring from backup).
- **Keygen entry points**: at boot, `NodeDB` calls `generateKeyPair` (or `regeneratePublicKey` when a stored private key is present and passes a low-entropy check) **directly** when `!owner.is_licensed` and `config.lora.region != UNSET`. `ensurePkiKeys` wraps the same logic for runtime/admin flows — it's the path `AdminModule::handleSetConfig` runs when first assigning a valid region or when security config is written; **do not assume it's the universal boot-time gate**, because the NodeDB path bypasses it.
- **Handshake**: `Curve25519::dh2(local_private, remote_public) → 32-byte shared secret → SHA-256 → 32-byte AES-256 key`. Recomputed per packet. The SHA-256 step is effectively a KDF over the raw ECDH output.
- **Cipher**: AES-256-CCM via `aes_ccm_ae` / `aes_ccm_ad` (`src/mesh/aes-ccm.cpp`). MAC length (the `M` parameter) is **8 bytes**. No AAD — the MAC covers ciphertext only.
- **Nonce (13 bytes / 104 bit)**: `aes_ccm_ae`/`aes_ccm_ad` use a 13-byte CCM nonce (`L = 2` is hardcoded in `src/mesh/aes-ccm.cpp`), not a 16-byte nonce. For PKI packets, `CryptoEngine::initNonce(fromNode, packetNum, extraNonce)` starts from the usual packet-derived nonce material, then overwrites nonce bytes `4..7` with a fresh 32-bit `extraNonce = random()`. The effective nonce bytes are therefore: bytes `0..3` = `packet_id`, bytes `4..7` = transmitted `extraNonce`, bytes `8..11` = `from_node`, byte `12` = `0x00`. The receiver reconstructs the same 13-byte nonce from the packet metadata plus the appended `extraNonce`.
- **Wire overhead**: 12 bytes appended to the ciphertext = 8-byte MAC ‖ 4-byte extraNonce. Defined as `MESHTASTIC_PKC_OVERHEAD = 12` in `src/mesh/RadioInterface.h`. Only the 4-byte `extraNonce` is sent; the rest of the 13-byte CCM nonce is reconstructed from packet fields as described above. The Router's send path checks this overhead against `MAX_LORA_PAYLOAD_LEN` before committing to PKI.
- **Send selection** (`Router::send`): the sender enters the PKI path when **all** hold — we're the originator AND not Ham mode AND not Portduino simradio AND not on the `serial`/`gpio` channels (unless the packet is already marked `pki_encrypted`) AND `config.security.private_key.size == 32` AND destination is a single node (not broadcast) AND the portnum isn't infrastructure. `TRACEROUTE_APP`, `NODEINFO_APP`, `ROUTING_APP`, and `POSITION_APP` are routed through channel encryption even when DMed (these need to be readable by relaying peers). Once on the PKI path, if the destination's public key isn't in our NodeDB the send **fails** with `PKI_SEND_FAIL_PUBLIC_KEY` — it does not silently fall back to channel encryption. If the client explicitly set `pki_encrypted=true` and any condition blocks PKI, the send fails with `PKI_FAILED`.
- **Receive selection** (`Router::perhapsDecode`): try PKI decrypt first when `channel == 0` AND `isToUs(p)` AND not broadcast AND both peers have public keys in NodeDB AND `rawSize > MESHTASTIC_PKC_OVERHEAD`. On success the packet gets `pki_encrypted=true` stamped and the sender's public key copied into `p->public_key` for downstream authorization.
-
-### Remote admin authorization
-
-Implemented in `src/modules/AdminModule.cpp` → `handleReceivedProtobuf`. The authorization check runs in this order:
-
-1. **Response messages** — if `messageIsResponse(r)` is true (the payload is a response to one of our earlier admin requests), it's accepted without any further check. The in-file comment flags this as a known-untightened gap: a stricter implementation would remember which `public_key` we last queried and reject responses that don't match.
-2. **Local admin** — `mp.from == 0` (phone app over BLE, serial CLI, internal module); never travels over the air. **Rejected** if `config.security.is_managed` is true, because managed devices expect admin to arrive over the air through an authorized remote path.
-3. **Legacy admin channel (deprecated)** — the packet arrived on a channel named literally `"admin"`. Gated by `config.security.admin_channel_enabled`; returns `NOT_AUTHORIZED` if the flag is false. Kept for backward compatibility; new deployments should use PKI admin.
-4. **PKI admin (preferred for remote)** — `mp.pki_encrypted == true` AND `mp.public_key` matches one of `config.security.admin_key[0..2]` (up to three authorized 32-byte Curve25519 public keys, typically copied from the admin node's own `user.public_key`).
-5. **Fallthrough** → `NOT_AUTHORIZED`.
-
-On top of authorization, any remote admin message that **mutates** state (not a request, not a response) also has to pass a session-key check (`checkPassKey`): the client must first pull a fresh 8-byte `session_passkey` via `get_admin_session_key_request`, then echo that passkey back in the mutating message. The device rotates the passkey after 150 s and rejects values older than 300 s — a narrow anti-replay window on top of the PKI layer.
-
-`config.security.is_managed = true` disables **local** admin writes (`mp.from == 0` is rejected). It does not by itself force every admin action through PKI — the legacy `"admin"` channel still authorizes remote admin when `config.security.admin_channel_enabled == true`. The AdminModule refuses to persist `is_managed=true` unless at least one `admin_key` is populated — a deliberate guard against operators locking themselves out.
-
-### Key-rotation hazards (actions that invalidate peers)
-
- **`factory_reset_device`** (the "full" variant, calls `NodeDB::factoryReset(eraseBleBonds=true)`) → **wipes** the X25519 private key; a fresh keypair is generated on the next region-set. Every existing peer holds the old public key, so DMs to this node silently fail PKI decrypt until every peer re-exchanges NodeInfo.
- **`factory_reset_config`** (the "partial" variant, calls `NodeDB::factoryReset()` with `eraseBleBonds=false`) → **preserves** the X25519 private key in `installDefaultConfig(preserveKey=true)`; the public key is zeroed and gets rebuilt from the preserved private key on the next boot via the NodeDB path's `regeneratePublicKey` call. Identity is preserved and the mesh does not need to re-exchange keys.
- **`region=UNSET → valid region`** → `ensurePkiKeys` runs inside the same `handleSetConfig` path; missing keys get generated at that moment.
- **Ham mode transitions** — entering Ham mode (`user.is_licensed=true`) runs `Channels::ensureLicensedOperation`, which **wipes every channel PSK** (all traffic becomes cleartext) and disables the legacy admin channel. The X25519 private key is preserved on the device but not used because `Router::send` skips PKI when `owner.is_licensed` is true. Leaving Ham mode re-enables PKI with the preserved keypair but does not restore the wiped channel PSKs — the operator has to re-set them.
- **Channel 0 PSK change** → every peer must re-learn the channel hash; cached NodeInfo becomes temporarily unreachable until the next broadcast.
- **`security.private_key` blanked via admin** → regenerates both halves (unless in Ham mode) and propagates the new public key via NodeInfo.

- **USB power control** (via `uhubctl`, per-port PPPS toggle): `uhubctl_list` (read-only), `uhubctl_power(action='on'|'off', confirm=True)`, `uhubctl_cycle(delay_s, confirm=True)`. Target by raw `(location, port)` or by `role` (`"nrf52"`, `"esp32s3"`); role lookup checks `MESHTASTIC_UHUBCTL_LOCATION_<ROLE>` + `_PORT_<ROLE>` env vars first, falls back to VID auto-detection.
- **Observability** (UI tier + operator ad-hoc): `capture_screen(role, ocr=True)` — grabs a USB-webcam frame of the device OLED and optionally OCRs it. Requires `mcp-server[ui]` extras (`opencv-python-headless`, `easyocr`) and `MESHTASTIC_UI_CAMERA_DEVICE_<ROLE>` env var; falls through to a 1×1 black PNG `NullBackend` when unconfigured.

-`confirm=True` is a tool-level gate on top of whatever permission prompt your MCP host shows. **Don't bypass it** by asking the host to auto-approve — it exists specifically because MCP hosts sometimes remember "always allow this tool" and that's dangerous for `factory_reset`, `erase_and_flash`, `uhubctl_power(action='off')`, and `uhubctl_cycle`.

-**TCP / native-host nodes.** Setting `MESHTASTIC_MCP_TCP_HOST=<host[:port]>` makes `list_devices` surface a `meshtasticd` daemon (e.g. the `native-macos` build) as a synthetic `tcp://host:port` entry, and `connect()` routes through `meshtastic.tcp_interface.TCPInterface` instead of `SerialInterface`. Every read/write/admin tool that flows through `connect()` works against the daemon transparently. USB-only tools (`pio_flash`, `erase_and_flash`, `update_flash`, `touch_1200bps`, `serial_open`, `esptool_*`, `nrfutil_*`, `picotool_*`) raise a clear `ConnectionError` when handed a `tcp://` port; `pio_flash` against a `native*` env raises a `FlashError` (no upload step — use `build` and run the binary directly). The pytest harness still assumes USB-attached devices per role; TCP-aware fixtures are deferred. See `mcp-server/README.md` § "TCP / native-host nodes".

-## Encryption at a glance
-
-Two layers, both in `src/mesh/CryptoEngine.cpp`:
-
- **Channel (symmetric)** — **AES-CTR** with a channel-wide PSK (AES-128 or AES-256). Nonce = packet_id ‖ from_node ‖ block_counter. No AEAD; integrity is soft (channel-hash filter). The well-known default PSK lives in `src/mesh/Channels.h`; a 1-byte PSK is a short-form index into it.
- **Per-peer PKI** — **X25519 ECDH** (Curve25519, 32-byte keys) → SHA-256 → **AES-256-CCM** with an 8-byte MAC. Fresh 32-bit `extraNonce` per packet, sent in the clear alongside the MAC. 12-byte wire overhead (`MESHTASTIC_PKC_OVERHEAD`). Used for DMs. Also used for remote admin (`src/modules/AdminModule.cpp`), where AdminMessage authorization is gated by `config.security.admin_key[0..2]`. Disabled entirely in Ham mode (`user.is_licensed=true`).
-
-Key rotation to never trigger casually: only the **full** factory reset (`factory_reset_device`, `eraseBleBonds=true`) wipes `security.private_key` and regenerates the keypair — every peer holds the old public key, so DMs silently fail PKI decrypt until NodeInfo re-exchanges. The **partial** config reset (`factory_reset_config`) preserves the private key and doesn't invalidate peer relationships. Explicitly blanking `security.private_key` via admin also triggers regen. See the **Encryption & Key Management** section of `.github/copilot-instructions.md` for the full spec (nonce layout, send/receive selection logic including infrastructure-portnum exceptions, admin-key + session-passkey authorization, `is_managed` scope, key-rotation hazards).
-
 ## House rules

 - **No destructive device operations without operator approval.** `factory_reset`, `erase_and_flash`, `reboot`, `shutdown`, history-rewriting git ops — describe the action and stop. Operator authorizes.

 ## Recovery one-liners

 - **`userPrefs.jsonc` dirty after a test run?** Re-run `./mcp-server/run-tests.sh` once (pre-flight self-heals from the sidecar). If still dirty: `git checkout userPrefs.jsonc`.
 - **nRF52 not responding?** `mcp__meshtastic__touch_1200bps(port=...)` drops it into the DFU bootloader, then `pio_flash` re-installs.
- **Device fully wedged (no DFU)?** `mcp__meshtastic__uhubctl_cycle(role="nrf52", confirm=True)` hard-power-cycles it via USB hub PPPS. Needs `uhubctl` installed (`brew install uhubctl` / `apt install uhubctl`); on Linux without udev rules, permission errors fail fast, so use `sudo uhubctl` yourself or configure udev access.
 - **Port busy?** `lsof <port>` to find the holder. Usually a stale `pio device monitor` or zombie `meshtastic_mcp` process. Kill it.
 - **Multiple MCP servers running?** `ps aux | grep meshtastic_mcp` — zombies hold ports. Kill all but the one your host spawned.
- **macOS: `LIBUSB_ERROR_BUSY` on a CH341 LoRa adapter?** A third-party WCH `CH34xVCPDriver` is claiming interface 0. Find the bundle ID with `ioreg -p IOUSB -l -w 0 | grep -B2 -A30 0x5512`, then `sudo kmutil unload -b <bundleID>`. Apple's bundled CH34x kext targets the CH340 UART (PID 0x7523), not the SPI bridge — it's never the culprit.

-| Var                                  | Purpose                                                                                                                                                                                                    |
-| ------------------------------------ | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
-| `MESHTASTIC_MCP_ENV_<ROLE>`          | Override PlatformIO env for a role (e.g. `MESHTASTIC_MCP_ENV_NRF52=rak4631-dap`). Default map: `nrf52→rak4631`, `esp32s3→heltec-v3`.                                                                       |
-| `MESHTASTIC_MCP_SEED`                | PSK seed for the session test profile. Defaults to `mcp-<user>-<host>`.                                                                                                                                    |
-| `MESHTASTIC_MCP_FLASH_LOG`           | File path to tee pio/esptool/nrfutil/picotool output. `run-tests.sh` sets this to `tests/flash.log` so the TUI can stream live flash progress.                                                             |
-| `MESHTASTIC_MCP_TCP_HOST`            | `host` or `host:port` of a `meshtasticd` daemon (e.g. the `native-macos` build). Surfaces it in `list_devices` as `tcp://host:port` so `connect()`-based tools target it transparently. Default port 4403. |
-| `MESHTASTIC_UHUBCTL_BIN`             | Absolute path to `uhubctl` binary. Default: PATH lookup.                                                                                                                                                   |
-| `MESHTASTIC_UHUBCTL_LOCATION_<ROLE>` | Pin a role to a specific uhubctl hub location (e.g. `1-1.3`). Wins over VID auto-detection — use when multiple devices share a VID.                                                                        |
-| `MESHTASTIC_UHUBCTL_PORT_<ROLE>`     | Pin a role to a specific hub port number. Required alongside `LOCATION_<ROLE>`.                                                                                                                            |
-| `MESHTASTIC_UI_CAMERA_BACKEND`       | Camera backend for UI tier + `capture_screen` tool: `opencv` / `ffmpeg` / `null` / `auto` (default).                                                                                                       |
-| `MESHTASTIC_UI_CAMERA_DEVICE`        | Generic camera device (index or path). Used by the UI tier when no per-role var is set.                                                                                                                    |
-| `MESHTASTIC_UI_CAMERA_DEVICE_<ROLE>` | Per-role camera pinning (e.g. `MESHTASTIC_UI_CAMERA_DEVICE_ESP32S3=0` for the OLED-bearing heltec-v3).                                                                                                     |
-| `MESHTASTIC_UI_OCR_BACKEND`          | OCR engine selection: `easyocr` / `pytesseract` / `null` / `auto` (default).                                                                                                                               |
-| `MESHTASTIC_UI_TUI_CAMERA`           | Set to `1` to mount the live camera-feed panel in `meshtastic-mcp-test-tui`.                                                                                                                               |

-
-## TCP / native-host nodes
-
-The `native-macos` and `native` PlatformIO envs build a headless `meshtasticd`
-binary that runs on the host (Apple Silicon / Intel macOS, or Linux Portduino).
-The daemon exposes the meshtastic TCP API on port `4403` rather than a USB
-serial endpoint — point the MCP server at it via `MESHTASTIC_MCP_TCP_HOST`:
-
-```bash
-# 1. Build + run a daemon on this host (see variants/native/portduino/platformio.ini
-#    for full Homebrew prereqs and CH341 LoRa-adapter setup).
-pio run -e native-macos
-~/.meshtasticd/meshtasticd
-
-# 2. Point the MCP server at it.
-export MESHTASTIC_MCP_TCP_HOST=localhost     # or host:port, default port 4403
-```
-
-**First-run gotcha — MAC address.** `meshtasticd` derives its MAC from the
-USB adapter's serial-number / product strings. Many cheap CH341 dongles
-(MeshStick included — VID 0x1A86 / PID 0x5512) ship with `iSerialNumber=0`
-and `iProduct=0`, so the daemon aborts on boot with `*** Blank MAC Address
-not allowed!`. Set the MAC explicitly in `config.yaml`:
-
-```yaml
-# Under General:
-MACAddress: 02:CA:FE:BA:BE:01
-```
-
-Use a locally-administered address (first byte's second-LSB set, e.g.
-`02:*` / `06:*` / `0A:*` / `0E:*`) to avoid colliding with a real OUI.
-
-There is also a `--hwid AA:BB:CC:DD:EE:FF` CLI flag visible in
-`meshtasticd --help`, but it is **currently broken** in
-`MAC_from_string()` (`src/platform/portduino/PortduinoGlue.cpp`): the
-function strips colons from its parameter but then reads bytes from the
-global `portduino_config.mac_address`, so `--hwid` is silently overridden
-when `MACAddress:` is also set, and crashes the daemon (uncaught
-`std::invalid_argument: stoi: no conversion`) when it isn't. Use the YAML
-form until that's fixed upstream.
-
-`list_devices` will surface the daemon as `tcp://localhost:4403` with
-`likely_meshtastic=True`, so `device_info`, `list_nodes`, `get_config`,
-`set_config`, `set_owner`, `send_text`, `userprefs_*`, and the admin RPCs
-auto-select it when no `port` is passed. Pass `port="tcp://other-host:9999"`
-explicitly to target a different daemon.
-
-**Tools that don't apply to a TCP/native node** (no USB hardware to operate
-on) raise a clear `ConnectionError` rather than failing mysteriously:
-`pio_flash`, `erase_and_flash`, `update_flash`, `touch_1200bps`,
-`serial_open` (use info/admin tools directly), and the vendor escape hatches
-`esptool_*`, `nrfutil_*`, `picotool_*`. `pio_flash` against a `native*` env
-similarly raises — there's no upload step; use `build` and run the binary
-directly.
-
-The pytest harness in `tests/` still assumes USB-attached devices per role —
-TCP-aware fixtures are not part of this surface yet.

-#### UI tier setup
-
-The `tests/ui/` tier drives the on-device OLED via the firmware's existing
-`AdminMessage.send_input_event` RPC (no firmware changes required) and
-verifies transitions via a macro-gated log line + camera + OCR. Summary:
-
-1. Install extras: `pip install -e 'mcp-server/.[ui]'` — pulls in
-   `opencv-python-headless`, `numpy`, `easyocr`, `Pillow`. First easyocr
-   run downloads ~100 MB of models to `~/.EasyOCR/`; an autouse session
-   fixture pre-warms the reader so per-test OCR is <100 ms after that.
-2. Point a USB webcam at the heltec-v3 OLED. Discover its index:
-   ```bash
-   .venv/bin/python -c "import cv2; [print(i, cv2.VideoCapture(i).read()[0]) for i in range(5)]"
-   ```
-3. Export the per-role device env var:
-   ```bash
-   export MESHTASTIC_UI_CAMERA_DEVICE_ESP32S3=0
-   ```
-4. Run:
-   ```bash
-   ./run-tests.sh tests/ui -v
-   ```
-   Captures land under `tests/ui_captures/<session_seed>/<test_id>/`, one
-   PNG + `.ocr.txt` per `frame_capture()` call, with a per-test
-   `transcript.md` stepping through event → frame → OCR. The HTML report
-   embeds the full image strip inline (pass or fail).
-
-On macOS, `cv2.VideoCapture(0)` triggers the TCC Camera permission prompt
-on first use. Pre-grant Terminal (or your IDE's terminal) before running.
-The `OpenCVBackend` fails fast on 10 consecutive black frames so a silent
-permission denial surfaces as a clear error, not an empty PNG strip.
-
-No camera? Set `MESHTASTIC_UI_CAMERA_BACKEND=null` (or leave the device var
-unset). Tests still exercise the event-injection path and log assertions;
-captures just become 1×1 black PNGs.

- `ffmpeg` — subprocess shelling out to the system `ffmpeg` binary. Slower

- `null` — no-op stub returning a 1×1 black PNG. Used when no camera is

-  `ffmpeg --version` resolves, else null.
- `MESHTASTIC_UI_CAMERA_DEVICE` — generic default (index or path).
- `MESHTASTIC_UI_CAMERA_DEVICE_<ROLE>` — per-role override, e.g.
-  `MESHTASTIC_UI_CAMERA_DEVICE_ESP32S3=0` for the OLED-bearing heltec-v3.

-a physical unplug. uhubctl toggles VBUS per-port on any hub with Per-Port
-Power Switching (PPPS) support — which is most externally-powered hubs
-from the last ~5 years — so the harness can power-cycle a device
-programmatically.
-
-Architecture:
- `list_hubs()` parses `uhubctl` default output into structured records.
- `find_port_for_vid(vid)` walks the hubs to find which location+port
-  hosts a given USB VID.
- `resolve_target(role)` is the public entry for callers that know a role
-  (`nrf52`, `esp32s3`) but not a hub location: env-var pins win, VID
-  auto-detect falls back.
- `power_on`, `power_off`, `cycle` wrap the corresponding `uhubctl -a`
-  invocations, routed through `hw_tools._run` so they share tee-to-flash-
-  log + timeout handling with esptool / nrfutil / picotool.
-
-Sudo policy: **fail fast**. Modern macOS + most PPPS-capable hubs work
-without root, but Linux without udev rules (or old macOS with specific
-driver quirks) still needs it. We run uhubctl non-root; if stderr
-matches the classic permission pattern we raise `UhubctlError` with an
-install hint pointing at the uhubctl docs. Auto-wrapping with `sudo`
-would prompt in the middle of test runs — bad for CI.

-        - Size: 4.7 inch
-        - Physical resolution: 960px x 540px
-        - Interface: 8-bit parallel (NOT SPI)
-
-    Unlike the other NicheGraphics EInk drivers, this one drives a parallel e-paper
-    panel via the FastEPD library. SPI parameters passed to begin() are ignored.
-
-    The ED047TC1 panel has an inactive pixel border on all four edges (~4–8 physical
-    pixels). DISPLAY_WIDTH / DISPLAY_HEIGHT expose a reduced "safe area" to InkHUD so
-    that content is never drawn into this dead zone. The update() method copies the
-    InkHUD frame buffer into the centre of the larger physical 960×540 buffer, using
-    H_OFFSET_BYTES (horizontal, whole bytes = 8 pixels per byte),
-    V_OFFSET_TOP and V_OFFSET_BOTTOM (vertical, pixel rows) to position it.
-
-    Changing these constants shifts content inward from each physical edge:
-        H_OFFSET_BYTES = 1  →  8px left margin, 8px right margin   (960 – 8 – 8   = 944)
-        V_OFFSET_TOP   = 9  →  9px top margin  (asymmetric: top ≠ bottom)
-        V_OFFSET_BOTTOM = 8 →  8px bottom margin                    (540 – 9 – 8   = 523)
