Every explorer shows what happened on a chain. None shows the difference
between what a chain can do and what it has done, because none holds the
runtime's declared surface next to the activity. We already hold both, so this
is a join rather than new indexing.
quantus v152 6 of 58 dispatchables used
heisenberg v148 6 of 58 — and a different six
The gap is the interesting half. ReversibleTransfers, TechReferenda, Vesting
and Preimage are shipped, documented and untouched; "this chain has governance
nobody has used" is a different statement from "this chain has no governance",
and only one of them appears on a list of what happened. Unused calls keep their
signature and their docs, both read from the chain rather than a source tree,
and are dimmed rather than hidden.
Two chains on the same runtime family diverging is the other thing it surfaces:
mainnet has exercised the wormhole batch verifiers and nothing else, while
Heisenberg has a whole multisig lifecycle and no wormhole traffic.
`/:chain/call/:pallet/:call` is the feed behind a row — who dispatched it, with
what arguments, and whether it worked. Nothing is written per call type: the
arguments render through the same `Payload` as everything else, so a pallet
added next year gets a row on the index when the runtime declares it and a
working page the moment somebody uses it.
`BlockExtrinsic` gained `height` and `at`, which are redundant on a block's own
page and the entire point on a feed where every row is a different block.
