Note that [§ 4.17](https://zips.z.cash/protocol/protocol.pdf#chainvaluepoolbalances) ‘Chain Value Pool Balances’ already defines "transparent chain value pool balance".

"Total input value" is defined in § 7.1.2 ‘Transaction Consensus Rules’. ZIP 271 does not currently specify this change.

This needs to be compatible with quantum resilience.

Reconsider note selection and pool-crossing policy to favour migration to Orchard

Currently `propose_transaction` implements a best-effort policy to avoid pool-crossing, as follows: ```rust /// Performs input selection and returns a proposal for transaction construction including /// change and fee outputs. ///...

Rename them to `TxVersion::{V3,V4,V5}`. See https://github.com/zcash/librustzcash/pull/1718/files#r2056681390 for rationale.

This representation would be normalized (unlike the current one that requires an additional integer overlapping the bits of the big-endian index), easily sortable in SQL, and easy to check in...

librustzcash_sapling_generate_r generates alpha from 64 rather than 80 bytes of randomness

This is mainly a technicality; 64 bytes should be sufficient for security and the resulting alpha will be adequately uniform. However, it was specified as 640 bits, i.e. 80 bytes...
