+```bash
+~/.platformio/penv/bin/python -m platformio test -e native -f test_your_suite > /tmp/test_out.txt 2>&1
+grep -E 'error:|PASS|FAIL|succeeded|failed' /tmp/test_out.txt
+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.

 We keep this separate latest-message cache for this purpose, because:
 
-- it is cleared by an outgoing text message
-- we want to store both a recent broadcast and a recent DM
+- we want to expose both the most recent broadcast and most recent DM independently
+- applets like `DMApplet` and `NotificationApplet` need quick access without scanning the full message history
+
+#### How messages reach the store
+
+Broadcasts and DMs take different paths into `messageStore`:
+
+- **Broadcasts** — `ThreadedMessageApplet::handleReceived()` calls `messageStore.addFromPacket()`. `Events::onReceiveTextMessage()` then updates `latestMessage.broadcast` separately for fast access by `AllMessageApplet` and `NotificationApplet`.
+- **DMs** — `ThreadedMessageApplet` skips DMs entirely. `Events::onReceiveTextMessage()` calls `messageStore.addFromPacket()` directly and stores the result in `latestMessage.dm`.
 
 #### Saving / Loading
 
-_A bit of a hack.._
-Stored to flash using `InkHUD::MessageStore`, which is really intended for storing a thread of messages (see `ThreadedMessageApplet`). Used because it stores strings more efficiently than `FlashData.h`.
+The `LatestMessage` cache is not persisted to its own file. On boot, `InkHUD::begin()` calls `messageStore.loadFromFlash()` first, then `Persistence::loadLatestMessage()` rebuilds the cache by scanning the loaded messages for the most recent broadcast and DM.
 
-The hack is:
-
-- If most recent message was a DM, we only store the DM.
-- If most recent message was a broadcast, we store both a DM and a broadcast. The DM may be 0-length string.
+Text is stored in the firmware-wide shared text pool. Use `MessageStore::getText(msg)` to retrieve it from a `StoredMessage`.

 Applets themselves do also listen separately for various events, but for the purpose of gathering information which they would like to display.
 
+#### Text Messages
+
+`Events::onReceiveTextMessage()` is the central handler for all incoming text messages. It updates the `LatestMessage` cache and, for DMs, also adds the message to `messageStore` (since `ThreadedMessageApplet` only handles broadcasts). See `Persistence::LatestMessage` for details on how the two message types are stored.
+
 #### Buttons
 
 Button input is sometimes handled by a system applet. `InkHUD::Events` determines whether the button should be handled by a specific system applet, or should instead trigger a default behavior
 
 #### Factory Reset
 
-The Events class handles the admin messages(s) which trigger factory reset. We set `Events::eraseOnReboot = true`, which causes `Events::onReboot` to erase the contents of InkHUD's data directory. We do this because some applets (e.g. ThreadedMessageApplet) save their own data to flash, so if we erased earlier, that data would get re-written during reboot.
+The Events class handles the admin message(s) which trigger factory reset. We set `Events::eraseOnReboot = true`, which causes `Events::onReboot` to erase the contents of InkHUD's data directory (`/NicheGraphics/`) and also call `messageStore.clearAllMessages()` to wipe the firmware-wide message store (`/Messages_default.msgs`). Both are cleared during reboot rather than earlier, to avoid data being re-written by applets still running before shutdown.
