Adds a deny entry for `is-terminal` to stop it from secretly reappearing.
Restores the `is-terminal` patch for `is_terminal_polyfill` to have one less
external dependency.
This helps identify where the various functionalities are used, or rather, not
used. The `Ciphersuite` trait present in `patches/ciphersuite`, facilitating
the entire FCMP++ tree, only requires the markers _and_ canonical point
decoding. I've opened a PR to upstream such a trait into `group`
(https://github.com/zkcrypto/group/pull/68).
`WrappedGroup` is still justified for as long as `Group::generator` exists.
Moving `::generator()` to its own trait, on an independent structure (upstream)
would be massively appreciated. @tarcieri also wanted to update from
`fn generator()` to `const GENERATOR`, which would encourage further discussion
on https://github.com/zkcrypto/group/issues/32 and
https://github.com/zkcrypto/group/issues/45, which have been stagnant.
The `Id` trait is occasionally used yet really should be first off the chopping
block.
Finally, `WithPreferredHash` is only actually used around a third of the time,
which more than justifies it being a separate trait.

Updates `dalek_ff_group::Scalar` to directly re-export
`curve25519_dalek::Scalar`, as without issue. `dalek_ff_group::RistrettoPoint`
also could be replaced with an export of `curve25519_dalek::RistrettoPoint`,
yet the coordinator relies on how we implemented `Hash` on it for the hell of
it so it isn't worth it at this time. `dalek_ff_group::EdwardsPoint` can't be
replaced for an re-export of `curve25519_dalek::SubgroupPoint` as it doesn't
implement `zeroize`, `subtle` traits within a released, non-yanked version.
Relevance to https://github.com/serai-dex/serai/issues/201 and
https://github.com/dalek-cryptography/curve25519-dalek/issues/811#issuecomment-3247732746.
Also updates the `Ristretto` ciphersuite to prefer `Blake2b-512` over
`SHA2-512`. In order to maintain compliance with FROST's IETF standard,
`modular-frost` defines its own ciphersuite for Ristretto which still uses
`SHA2-512`.
For backwards compatibility, we now use as a patch (as prior done with
`ciphersuite`).
Removes `crypto-bigint 0.5` from the tree and shapes up what the next release
will look like.
Actually use the added `Allocations` abstraction
Start using the sessions API in the validator-sets pallet
Get a `substrate/validator-sets` approximate to compiling
Not only does this follow our general practice, the latest SCALE has a
possibly-lossy truncation in its current implementation for `enum`s I'd like to
avoid without simply silencing.
Enables representing IUMT within `StorageValues`. Applied to a variety of
values.
Fixes a bug where `Some([0; 32])` would be considered a valid block anchor.
The reasoning for it is documented with itself. The plan is to use it within
our header for committing to the DAG (allowing one header per epoch, yet
logarithmic proofs for any header within the epoch), the transactions
commitment (allowing logarithmic proofs of a transaction within a block,
without padding), and the events commitment (allowing logarithmic proofs of
unique events within a block, despite events not having a unique ID inherent).
This also defines transaction hashes and performs the necessary modifications
for transactions to be unique.
This does break borsh's definition of a Vec EXCEPT if the BoundedVec is
considered an enum. For sufficiently low bounds, this is viable, though it
requires automated code generation to be sane.
