Conway-era governance MCP tools, key-credentialed (script credentials
deferred to Phase 6).
aldabra-core/src/governance.rs (new ~500 LOC):
- DRepTarget enum + parse_drep_target (handles bech32 drep1.../
drep_script1... + named 'abstain' / 'no_confidence')
- build_signed_vote_delegation — Certificate::VoteDeleg(stake_cred,
drep), reuses the dual-witness 2-pass-fee pattern from stake.rs.
Optional register_first prepends StakeRegistration.
- build_signed_drep_registration — Certificate::RegDRepCert with
optional CIP-100/119 anchor + 500 ADA deposit
- build_signed_drep_deregistration — Certificate::UnRegDRepCert with
refund-aware change calc (deposit returns to wallet)
- DREP_REGISTRATION_DEPOSIT_LOVELACE constant (500 ADA, mainnet)
Made stake_key_as_payment_proxy pub(crate) so governance.rs can reuse
the stake-key-as-witness trick.
aldabra-mcp/src/tools.rs:
- wallet_vote_delegate (drep + register_first)
- wallet_drep_register (optional anchor_url + anchor_data_hash_hex)
- wallet_drep_deregister (no args)
3 unit tests on parse_drep_target + DRepTarget→DRep round-trip.
Phase 6 (vote_cast for DReps voting on Conway gov actions) blocked
on extending Sulkta-Coop/pallas-txbuilder to thread voting_procedures
through StagingTransaction (currently TODO at conway.rs:254). Same
pattern as the aux_data + certificates patches already in the fork.
Estimated ~300-500 LOC fork patch + ~400 LOC vote-cast builder. Surface
to Cobb before starting.
