Adds a minimal amount of packages. Does add decent complexity. Avoids having
constants which aren't exact, due to things like the quadratic memory cost, and
the issues with such estimates accordingly.
It had sequential async calls with complexity O(n), with a variety of redundant
calls. There was also a constant of... 4? 5? for each item. Now, the total
sequence depth is just 3-4.
Completes the `Executed` enum in the router. Adds an `Escape` struct. Both are
needed for testing purposes.
Documents the gas constants in intent and reasoning.
Adds modernized tests around key rotation and the escape hatch.
Also updates the rest of the codebase which had accumulated errors.
This isn't necessary. Because we just log the error, we never match off of it,
we don't need any structure beyond String (or now Debug, which still gives us
a way to print the error). This is for the ergonomics of not having to
constantly write `.map_err(|e| format!("{e:?}"))`.
Renames `label` to `round` since `Label` was renamed to `SigningProtocolRound`.
Adds some more context-less validation to transactions which used to be done
within the custom decode function which was simplified via the usage of borsh.
Documents in processor-messages where the Coordinator sends each of its
messages.
It's not only helpful (to easily check where Serai's view of the external
network is) but it's necessary in case of a non-trivial chain fork to determine
which blockchain Serai considers canonical.
We read from it but never writ to it.
It was used to check we didn't flag a block as notable after reporting it, but
it was called by the scan task as it scanned a block. We only batch/report
blocks after the scan task after scanning them, so it was very redundant.
It's only there to make the VariantSignid unique across Sessions. By localizing
the VariantSignid to a Session, we avoid this, and can better ensure we don't
queue work for historic sessions.
This is incomplete at this time. The logic is fine, but needs to be moved to a
distinct location to handle singular blocks which produce multiple Batches.
