 By default the app relies on radio events plus MeshCore auto-fetch for incoming messages, and also runs a low-frequency hourly audit poll. That audit checks both:
 
 - whether messages were left on the radio without reaching the app through event subscription
 - whether the app's channel-slot expectations still match the radio's actual channel listing
 
-If the audit finds a mismatch, you'll see an error in the application UI and your logs. If you see that warning, or if messages on the radio never show up in the app, try `MESHCORE_ENABLE_MESSAGE_POLL_FALLBACK=true` to switch that task into a more aggressive 10-second safety net. If room sends appear to be using the wrong channel slot or another client is changing slots underneath this app, try `MESHCORE_FORCE_CHANNEL_SLOT_RECONFIGURE=true` to force the radio to validate the channel slot is valid before sending (will delay sending by ~500ms).
+If the audit finds a mismatch, you'll see an error in the application UI and your logs.
+
+### Message Poll Fallback
+
+If you see that warning, or if messages on the radio never show up in the app, try `MESHCORE_ENABLE_MESSAGE_POLL_FALLBACK=true` to switch that task into a more aggressive 10-second safety net.
+
+### Force Channel Slot Reconfigure
+
+If room sends appear to be using the wrong channel slot or another client is changing slots underneath this app, try `MESHCORE_FORCE_CHANNEL_SLOT_RECONFIGURE=true` to force the radio to validate the channel slot is valid before sending (will delay sending by ~500ms).
+
+### Clock Wraparound
 
 `__CLOWNTOWN_DO_CLOCK_WRAPAROUND=true` is a last-resort clock remediation for nodes whose RTC is stuck in the future and where rescue-mode time setting or GPS-based time is not available. It intentionally relies on the clock rolling past the 32-bit epoch boundary, which is board-specific behavior and may not be safe or effective on all MeshCore targets. Treat it as highly experimental.
 
+### Private Key Export
+
+`MESHCORE_ENABLE_LOCAL_PRIVATE_KEY_EXPORT=true` enables `GET /api/radio/private-key`, which returns the in-memory private key as hex for backup or migration. The key is held in memory only (exported from the radio on connect) and is never persisted to disk. Only enable this on a trusted network when you need to retrieve the key.
+
+Import via `PUT /api/radio/private-key` is always available regardless of this setting — it is write-only and does not expose key material.
+
+The Radio Settings config export/import feature uses these endpoints. When export is disabled, config exports will omit the private key and show a notice.
+
 ## Contact Loading Issues
 
 RemoteTerm loads favorite and recently active contacts onto the radio so that the radio can automatically acknowledge incoming DMs on your behalf. To do this, it first enumerates the radio's existing contact table, then reconciles it with the desired working set.

+- The telemetry collection loop in `radio_sync.py` is unified: it iterates over both `tracked_telemetry_repeaters` and `tracked_telemetry_contacts`, dispatching to `_collect_repeater_telemetry` (type 2) or `_collect_contact_telemetry` (others). The daily check ceiling uses the combined count.
