Remove unused Adafruit_SSD1306 library dependency

Move WiFi.onEvent(WiFiEvent) registration before createSSLCert() to
prevent a race where the ESP32 auto-reconnects during cert generation
and fires GOT_IP before the handler is attached, causing
onNetworkConnected() to never run and the TCP/HTTP API services to
never initialize when booting without USB serial.

Also call onNetworkConnected() from reconnectWiFi() on all platforms
(not just RP2040) as a safety net; it is already guarded by
APStartupComplete so it only runs once.

 - **`security.private_key` blanked via admin** → regenerates both halves (unless in Ham mode) and propagates the new public key via NodeInfo.
 
+## NodeDB Layout (v25)
+
+`DEVICESTATE_CUR_VER = 25`, `DEVICESTATE_MIN_VER = 24`. The on-device NodeDB was split in v25 into a slim header table plus four optional satellite stores. Older v24 saves auto-migrate at boot. Old training-data instincts (`node->user.long_name`, `node->position.latitude_i`, `node->is_favorite`, `node->device_metrics.battery_level`) are wrong now — the fields aren't there. Read this section before touching anything that walks `nodeDB->meshNodes`.
+
+### Slim `NodeInfoLite`
+
+`UserLite` is flattened onto `NodeInfoLite` (no nested sub-message); `position` and `device_metrics` are removed entirely (tags reserved). MAC address is dropped. Long names are capped at 25 chars (`max_size:25` in `deviceonly.options`); `hw_model` and `role` are `int_size:8`. Encoded size dropped from ~166 B → ~105 B per node.
+
+Booleans are bit-packed into `NodeInfoLite.bitfield`. **Do not read or write the bits directly** — use the inline helpers in `src/mesh/NodeDB.h`:
+
+```cpp
+nodeInfoLiteHasUser(n)                  // bit 5 — user fields populated
+nodeInfoLiteIsFavorite(n)               // bit 3
+nodeInfoLiteIsIgnored(n)                // bit 4
+nodeInfoLiteIsMuted(n)                  // bit 1
+nodeInfoLiteIsLicensed(n)               // bit 6 — Ham mode peer
+nodeInfoLiteIsKeyManuallyVerified(n)    // bit 0
+nodeInfoLiteHasIsUnmessagable(n)        // bit 8 — "is_unmessagable was sent"
+nodeInfoLiteIsUnmessagable(n)           // bit 7
+// via_mqtt is bit 2 (mask exposed; predicate uses the mask directly)
+
+nodeInfoLiteSetBit(n, NODEINFO_BITFIELD_IS_FAVORITE_MASK, true);  // setter
+```
+
+### Satellite stores
+
+Four `std::unordered_map<NodeNum, …>` members on `NodeDB`, each gated by its own build flag:
+
+| Map               | Value type                      | Build flag                         |
+| ----------------- | ------------------------------- | ---------------------------------- |
+| `nodePositions`   | `meshtastic_PositionLite`       | `MESHTASTIC_EXCLUDE_POSITIONDB`    |
+| `nodeTelemetry`   | `meshtastic_DeviceMetrics`      | `MESHTASTIC_EXCLUDE_TELEMETRYDB`   |
+| `nodeEnvironment` | `meshtastic_EnvironmentMetrics` | `MESHTASTIC_EXCLUDE_ENVIRONMENTDB` |
+| `nodeStatus`      | `meshtastic_StatusMessage`      | `MESHTASTIC_EXCLUDE_STATUSDB`      |
+
+Defaults are ON (i.e., maps **excluded**) for STM32WL only — see `src/mesh/mesh-pb-constants.h`. On every other arch all four maps are present. When excluded, the map member is absent and the corresponding accessors return `false`.
+
+All four maps are guarded by **`mutable concurrency::Lock satelliteMutex`** — concurrent access from receive threads, the phone API state machine, and the renderer is the rule, not the exception.
+
+### Accessor convention
+
+**Never hand out pointers into the maps.** Use the copy-out accessors on `NodeDB`:
+
+```cpp
+bool copyNodePosition(NodeNum, meshtastic_PositionLite &out)       const;
+bool copyNodeTelemetry(NodeNum, meshtastic_DeviceMetrics &out)     const;
+bool copyNodeEnvironment(NodeNum, meshtastic_EnvironmentMetrics &out) const;
+bool copyNodeStatus(NodeNum, meshtastic_StatusMessage &out)        const;
+```
+
+Each takes the lock, copies the value if present, returns `false` if the entry is absent or the DB is excluded. Pass-by-out-param is deliberate — pointer-style accessors would invite UAF and lock-leak bugs across the renderer. The "has any X" convenience predicates (`hasValidPosition` etc.) are implemented in terms of these.
+
+Writers go through `setNodeStatus`, `updatePosition`, `updateTelemetry` (which dispatches on `which_variant` for device vs environment metrics) — these own the lock and the eviction hooks.
+
+### 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, `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.
+
+### Sync flow: thin NodeInfo + post-COMPLETE_ID replay (no opt-in)
+
+There is no capability flag and no special "gradient" nonce. The **default** sync flow is:
+
+1. Config / module-config / channel / metadata segments (same as before).
+2. `STATE_SEND_OWN_NODEINFO` — **our own** NodeInfo, still bundled with our position and device_metrics (because the replay snapshot excludes our own NodeNum). Emitted via `ConvertToNodeInfo(lite)`.
+3. `STATE_SEND_OTHER_NODEINFOS` — every other peer's NodeInfo, **always thin** (no `position`, no `device_metrics`). Emitted via `ConvertToNodeInfoThin(lite)`.
+4. `STATE_SEND_FILEMANIFEST` → `STATE_SEND_COMPLETE_ID` — the phone sees `config_complete_id` and treats sync as done.
+5. `STATE_SEND_PACKETS` — live mesh packets, with a trailing replay drain interleaved. The replay drain walks four cached satellite stores in order (positions → telemetry → environment → status) and emits each cached entry as an ordinary `MeshPacket` on the matching portnum (`POSITION_APP`, `TELEMETRY_APP` device + environment variants, `NODE_STATUS_APP`). These are indistinguishable on the wire from live mesh traffic, so clients need no special handling — any code that already updates UI on `POSITION_APP` etc. works.
+
+`PhoneAPI::sendConfigComplete()` arms `replayPhase = REPLAY_PHASE_POSITIONS` for default/full sync and `SPECIAL_NONCE_ONLY_NODES`, while `SPECIAL_NONCE_ONLY_CONFIG` skips replay. The drain runs inside `STATE_SEND_PACKETS` via `popReplayPacket()`, lower priority than live traffic. When all four phases drain, `replayPhase` flips back to `REPLAY_PHASE_IDLE` and the snapshot vectors get `shrink_to_fit`ed.
+
+STM32WL and any other build with all four `MESHTASTIC_EXCLUDE_*DB` flags set produces zero replay packets — `popReplayPacket` advances through each phase in microseconds without emitting anything.
+
+Special nonces that still mean something:
+
+- `SPECIAL_NONCE_ONLY_CONFIG` (69420) — skip node sync entirely, just config.
+- `SPECIAL_NONCE_ONLY_NODES` (69421) — skip config segments, jump straight to `STATE_SEND_OWN_NODEINFO`. Still gets the post-COMPLETE_ID replay drain.
+
+There are no other reserved nonces; everything else is a fresh random `want_config_id` from the client.
+
+### v24 → v25 migration
+
+The legacy migration code lives in **`src/mesh/NodeDBLegacyMigration.cpp`**, not in `NodeDB.cpp`. It owns the `meshtastic_NodeDatabase_Legacy` callback and `NodeDB::migrateLegacyNodeDatabase()`. The legacy proto descriptor is `protobufs/meshtastic/deviceonly_legacy.proto` (only included by the migration TU). The boot path peeks the file's leading version tag, runs the migration if `version < 25`, then re-saves in v25 layout. The legacy descriptor is scheduled for removal once `DEVICESTATE_MIN_VER` is bumped.
+
+### Read-site rules of thumb
+
+- Never `node->position.X` / `node->device_metrics.X` — those fields no longer exist. Pull from the satellite map via `copyNodePosition` / `copyNodeTelemetry`.
+- Never `node->user.long_name` — `long_name`, `short_name`, `public_key`, `hw_model`, `role`, `macaddr` (gone), `is_licensed`, `is_unmessagable` are flat on `NodeInfoLite`.
+- Never `node->is_favorite` / `node->is_ignored` / `node->via_mqtt` / `node->is_key_manually_verified` — use the bitfield helpers.
+- Never assume `nodeDB->getMeshNode(num)->position.time` — call `copyNodePosition` and check the return.
+- Don't lock `satelliteMutex` yourself in renderer code; the copy-out accessors already do.
+
+Unit tests for the conversion layer live in `test/test_type_conversions/test_main.cpp` (Unity) — bitfield round-trips, `long_name` truncation, thin-vs-full conversions. Add cases there when extending the schema.

+target directory and rewrites every `meshtastic` reference (imports, dotted
+attribute access) to use the new namespace (e.g., `meshtastic_v25`).
+
+Why: the .proto files declare `package meshtastic;`, so protoc emits

+`meshtastic` package which other parts of the mcp-server depend on. Renaming

+"""Deterministic seed-data generator for the fake NodeDB fixture pipeline.
+
+Writes a JSONL file describing N fake-but-realistic Meshtastic peers.
+The output is hand-editable and committed; a sibling compile step
+(bin/seed-json-to-proto.py) turns it into a binary `meshtastic_NodeDatabase`
+v25 protobuf with fresh "now-relative" timestamps.
+
+Determinism contract:
+  Same --seed -> byte-identical JSONL output, regardless of wall clock.
+  All timestamps are stored as `*_offset_sec` (seconds before "now"); the
+  compile step resolves them to absolute epochs at compile time.
+
+Structural fields covered:
+  * NodeInfoLite header: num, long_name, short_name, hw_model, role,
+    public_key, snr, channel, hops_away, next_hop, bitfield flags
+  * PositionLite: lat/long Gaussian around --centroid, altitude, source
+  * DeviceMetrics: battery/voltage/util/uptime
+  * EnvironmentMetrics: temp/humidity/pressure/iaq
+  * StatusMessage: error_code (usually zero)
+
+Active-board allow-list:
+  hw_model values are restricted to the intersection of
+    (a) variants with `custom_meshtastic_support_level = 1` in
+        variants/*/*/platformio.ini, AND
+    (b) values present in the `HardwareModel` enum in mesh.proto.
+  See HW_MODEL_WEIGHTS below. Deprecated boards (legacy TLORA / Heltec V1-2 /
+  classic TBEAM / TBEAM_V0P7 / Nano G1 / etc.) and fuzzer-only sentinels
+  (PORTDUINO, ANDROID_SIM, DIY_V1, ...) are excluded.
+
+Active-role allow-list:
+  Excludes ROUTER_CLIENT (deprecated v2.3.15) and REPEATER (deprecated v2.7.11).

+"""Fake NodeDB fixture push — Portduino file copy + hardware XModem upload.
+
+The fixture pipeline is two-stage:
+  1. `bin/gen-fake-nodedb-seed.py` produces a deterministic JSONL describing N
+     fake-but-realistic peers. Committed under `test/fixtures/nodedb/`.
+  2. `bin/seed-json-to-proto.py` compiles JSONL → binary v25 NodeDatabase
+     protobuf with fresh wall-clock timestamps.
+
+This module exposes `push_fake_nodedb(...)`, the MCP tool that:
+  - target="portduino": compiles the JSONL into the device's prefs dir on
+    the local filesystem (`~/.portduino/<config>/prefs/nodes.proto`).
+  - target="hardware":  compiles to a temp file, then streams it over the
+    XModem protocol (via the meshtastic SerialInterface/BLEInterface +
+    `meshtastic.xmodempacket` pubsub topic) to `/prefs/nodes.proto` on the
+    device. Triggers a reboot so the firmware loads the new state on next
+    boot.
+
+XModem wire details (mirrors firmware impl at src/xmodem.cpp:115-260):
+  * 128-byte chunks; final chunk padded to 128 B with 0x1A (SUB) bytes.
+  * CRC16-CCITT (poly 0x1021, init 0x0000).
+  * SOH/seq=0 carries the destination filename in `buffer.bytes`. ACK if
+    `FSCom.open(filename, FILE_O_WRITE)` succeeds; NAK otherwise.
+  * SOH/seq≥1 carries a 128-byte chunk. ACK = advance; NAK = retransmit.
+  * EOT after the last chunk flushes + closes the file on-device.
+
+Hardware push requires `confirm=True` (mirrors factory_reset / erase_and_flash
+in the .github/copilot-instructions.md "never do these without asking" list).

+//                      deleted or the kThemes[] array is reordered.
+//   visible          - controls whether a theme appears in the picker menu.
+//                      Hidden themes can still be restored and applied if their

+// To retire a theme without breaking saved configs:
+//   - Preferred: keep the entry and set visible=false so existing saved
+//     uniqueIdentifier values still resolve to the same theme.
+//   - If you remove the entry, resolveThemeIndex() falls back to DefaultDark
