Scheduled transfers that have not yet landed, counting down to the block they execute at. `ReversibleTransfers` is the most distinctive thing this chain does and the observer said nothing about it. The only view here built from both halves, each authoritative about a different thing. State — `PendingTransfers` — says what is still pending: a cancelled or executed transfer is simply gone from the map, and that absence beats replaying every event since genesis and reconstructing the set, which fails silently. The event index says when each is due, because `TransactionScheduled` carries `execute_at` and, contrary to what the issue assumed, the stored struct does not. A transfer scheduled before the index reaches shows as pending with an unknown deadline rather than being dropped for half a story. Enumerating a map needs the prefix and `state_getKeysPaged` — there is no list, only keys derived from the things in it — and recovering a key from a storage key needs the hasher to have kept it. `Blake2_128Concat` and `Twox64Concat` do, `Twox128` and friends do not, so `key_offset` is `None` there rather than a guess. Verified against a populated map since the target one is empty: `System::Account` enumerates, its keys decode back to accounts, and the balances read. `execute_at` is a `DispatchTime<BlockNumber, Moment>` — an enum, so reading the wrong arm would show a millisecond timestamp as a height. Time remaining is an estimate from a block interval that moves; the block count is the fact and the page says so. The page reads "nothing is in flight" today, correctly and deliberately: zero of this pallet's six calls have been dispatched on mainnet. It exists before the first one because catching the first one is the point. CLAUDE.md gains the workflow this was the first of — issue first, closed by the commit, and corrections recorded as comments on the issue rather than as surprises in a diff.
