zeekay 2faf6ed0df The wire is ZAP: no codec, no marshal, no parallel wallet
github.com/luxfi/codec is gone from this module — no import, no call, no
require. Nothing here marshals or unmarshals a transaction any more.

WHY IT BROKE. codec deleted its jsonrpc subpackage (1b67d6a, "delete dead
subpackages") while nine files imported it. It looked dead because the
PUBLISHED [email protected] still ships it, so only a workspace build — which
resolves codec from the local checkout — ever saw the break.

THE WIRE. A tx already carries its own ZAP encoding, so the codec was
re-deriving what the tx could hand over:
  txs.Codec.Marshal(txs.CodecVersion, &tx.Unsigned)  ->  tx.Unsigned.Bytes()
                                                          txs.UnsignedBytes(tx.Unsigned)
  txs.Codec.Marshal(txs.CodecVersion, tx)            ->  tx.Initialize()
  txs.Codec.Unmarshal(txBytes, &tx)                  ->  txs.Parse(txBytes)
  codec.Unmarshal(utxoBytes, &utxo)                  ->  utxo.ParseUTXO(...)
These are the same calls the node makes in txs.Tx.Sign. AddAllUTXOs no longer
takes a codec.Manager, and SortTransferableOutputs / state.Sort /
SortOperations no longer get one — upstream dropped the parameter.

PARALLEL IMPLEMENTATIONS, DELETED. wallet/chain/{p,x} carried a second copy of
the builder and signer beside the subpackages that already held them —
p/signer_visitor.go and p/signer/visitor.go were both 399 lines of the same
thing, and each defect had to be fixed twice. The flat files are gone; the
package keeps the facade it already had in wallet_exports.go, which re-exports
the subpackage. -4787 lines.

wallet/chain/c is deleted. Its whole reason to exist was a codec.Manager
scaffold for C-chain atomic-tx wire that nothing runs: NewWallet was passed
nil for it, and the builder was commented out. The two symbols anything used
move to where they are read — Account, a balance and a nonce off an EVM
client, and EVMKeychain, the geth-address half of a keychain. Wallet no longer
advertises a C() that only ever returned nil.

ALIGNED. XAssetID -> UTXOAssetID, matching runtime.Runtime and netrunner, which
already expected it. Keychain GetEth -> GetByEVM, EthAddrs -> EVMAddrs. warp
UnsignedMessage and Message collapsed into one flat Message, so a signature is
an Envelope rather than a second message type. netrunner's HealthResponse is
read as a field: the getter form is protobuf, behind //go:build grpc, and the
default build is ZAP-native.

VERIFIED on a machine with the native libraries: go build ./... exits 0 with no
codec require in go.mod, and go test ./... is 23 ok. Three packages still fail
to build their tests — profiles, wallet/keychain, wallet/primary — and all
three fail identically on the tree before this change: Consensus,
VerifyHybridSecp256k1MLDSA and isXChainNotEnabled are referenced by tests and
defined nowhere. evm failed there too and now passes.
