related Codex Peer Context Records
Remote peer's Presence records are added to the remote peer context object (BlockExcPeerCtx) in one place only: BlockExcEngine.blockPresenceHandler.

We remove the records in BlockExcEngine.blockPresenceHandler (as part of filtering out irrelevant records), when canceling blocks (in response to receiving new block deliveries), and in the BlockExcEngine.blockPresenceHandler itself.

[!question] isn't the last one (calling cleanPresence in BlockExcEngine.blockPresenceHandler) a duplicate of resolveBlocks which calls cancelBlocks, which also calls cleanPresence ).`
