|
//
|
|
// - txs.GenesisCodec registers BOTH the v0 (v1.23.x Apricot/Banff)
|

// and v1 (current) tx slot maps, so it can decode v0-prefixed
|
|
// cached-genesis blobs that pre-date the codec bump. block.Genesis
|
|
// Codec carries only the v1 slot map and errors on prefix=0 with
|
|
// codec.ErrUnknownVersion — exactly the failure mode that broke
|
|
// v1.28.0 testnet canary at first-byte parse of
|
|
// <data>/genesis.bytes.
|
|
// - The outer Genesis struct itself has no slot ID; all version-
|
|
// sensitive data lives in the embedded []*txs.Tx (validators,
|
|
// chains). Decoding via txs.GenesisCodec is therefore exactly the
|
|
// dispatch we need — version is taken from the 2-byte wire prefix
|
|
// and routed to the v0 or v1 tx slot map.
|
|
// - Marshal at CodecVersion (== v1) is unchanged: the v1 slot map in
|
|
// txs.GenesisCodec is byte-for-byte identical to the v1 slot map in
|
|
// block.GenesisCodec (both come from registerV1TxTypes).
|
|
//
|
|
// All write paths (Genesis.Bytes, New, static_service) MUST continue to
|
|
// use CodecVersion. v0 is a READ-ONLY decoder.
