 - 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.

-## 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.

-        - ED047TC1 (via FastEPD library)
-        - Manufacturer: E Ink / used in LilyGo T5-E-Paper-S3-Pro
-        - 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)
