+/**
+ * Store and forward ++ module
+ * There's an obvious need for a store-and-forward mechanism in Meshtastic.
+ * This module takes heavy inspiration from Git, building a chain of messages that can be synced between nodes.
+ * Each message is hashed, and the chain is built by hashing the previous commit hash and the current message hash.
+ * Nodes can request missing messages by requesting the next message after a given commit hash.
+ *
+ * The current focus is text messages, limited to the primary channel.
+ *
+ * Each chain is identified by a root hash, which is derived from the channelHash, the local nodenum, and the timestamp when
+ * created.
+ *
+ * Each message is also given a message hash, derived from the encrypted payload, the to, from, id.
+ * Notably not the timestamp, as we want these to match across nodes, even if the timestamps differ.
+ *
+ * The authoritative node for the chain will generate a commit hash for each message when adding it to the chain.
+ * The first message's commit hash is derived from the root hash and the message hash.
+ * Subsequent messages' commit hashes are derived from the previous commit hash and the current message hash.
+ * This allows a node to see only the last commit hash, and confirm it hasn't missed any messages.
+ *
+ * Nodes can request the next message in the chain by sending a LINK_REQUEST message with the root hash and the last known commit
+ * hash. Any node that has the next message can respond with a LINK_PROVIDE message containing the next message.
+ *
+ * When a satellite node sees a new text message, it stores it in a scratch database.
+ * These messages are periodically offered to the authoritative node for inclusion in the chain.
+ *
+ * The LINK_PROVIDE message does double-duty, sending both on-chain and off-chain messages.
+ * The differentiator is whether the commit hash is set or left empty.
+ *
+ * When a satellite node receives a canonical link message, it checks if it has the message in scratch.
+ * And evicts it when adding it to the canonical chain.
+ *
+ * This approach allows a node to know whether it has seen a given message before, or if it is new coming via SFPP.
+ * If new, and the timestamp is within the rebroadcast timeout, it will process that message as if it were just received from the
+ * mesh, allowing it to be decrypted, shown to the user, and rebroadcast.
