feat(dao): proposal_vote.rs builder — Phase 3 unsigned tx
Mirrors proposal_create's shape: 3 inputs (stake script + proposal script + funding wallet), 2 reference inputs (stake validator + proposal validator), 2 outputs (mutated stake + mutated proposal + maybe change), 2 plutus spends (PermitVote + Vote tag), no mints. Pre-flight matches every Plutarch validator check from Agora/Proposal/Scripts.hs PVote (~L484) + Stake/Redeemers.hs ppermitVote (~L196): - voter pkh is owner OR delegatee - proposal status == VotingReady - stake doesn't already have Voted lock for this proposal_id - stake.staked_amount >= proposal.thresholds.vote (single-stake v1) - result_tag is in proposal.votes keys (== effects keys) - validity upper bound inside [starting_time + draft_time, starting_time + draft_time + voting_time] New stake datum prepends the Voted lock per paddNewLock = pcons. New proposal datum increments votes[result_tag] by stake amount; all other fields preserved bit-exact since validator does record `==`. Voted.posix_time = caller-supplied validity_upper_ms — matches PFullyBoundedTimeRange _ upperBound the validator extracts. Caller (MCP tool) computes ms-from-slot via mainnet Shelley genesis. 9 unit tests covering happy path + every preflight reject + delegated voter accepted.

//! Build a `dao_proposal_vote` transaction.
|
||||
//!
|
||||
//! This is the second DAO write path. The tx shape:
|
||||
//!
|
||||
//! - **Inputs**:
|
||||
//! - The voter's stake UTxO (Plutus spend, redeemer = `PermitVote`).
|
||||
//! - The target proposal UTxO (Plutus spend, redeemer = `Vote(result_tag)`).
|
||||
//! - One wallet UTxO funding fees + min-UTxO for the new outputs.
|
||||
//! - **Collateral input**: a separate ADA-only ≥5 ADA wallet UTxO.
|
||||
//! - **Reference inputs**:
|
||||
//! - Stake validator script.
|
||||
//! - Proposal validator script.
|
||||
//! - **No mints** — vote is a state transition only.
|
||||
//! - **Outputs**:
|
||||
//! - New stake UTxO at `stakes_addr`. Datum = old StakeDatum with a
|
||||
//! fresh `Voted { result_tag, posix_time = validity_upper_ms }`
|
||||
//! lock **prepended** to `locked_by` (per Agora's `paddNewLock = pcons`).
|
||||
//! StakeST + gov-token quantity preserved.
|
||||
//! - New proposal UTxO at `proposal_addr`. Datum = old ProposalDatum
|
||||
//! with `votes[result_tag] += stake.staked_amount`. Everything else
|
||||
//! preserved bit-exact (validator does record `==`).
|
||||
//! ProposalST preserved.
|
||||
//! - Wallet change.
|
||||
//!
|
||||
//! ## What the validator enforces (must match)
|
||||
//!
|
||||
//! From `Agora/Proposal/Scripts.hs` `PVote` branch (~line 484):
|
||||
//!
|
||||
//! 1. Stakes input: at least one. Sum of staked_amount ≥ thresholds.vote.
|
||||
//! 2. None of the input stakes already have a Voted lock for this proposal.
|
||||
//! 3. Status is `VotingReady`.
|
||||
//! 4. Tx validity range fully inside `[starting_time + draft_time,
|
||||
//! starting_time + draft_time + voting_time]`.
|
||||
//! 5. Validity range width ≤ `voting_time_range_max_width` (Sulkta: 30min).
|
||||
//! 6. result_tag is a key already in `proposal.votes`.
|
||||
//! 7. Output proposal datum equals input datum with **only**
|
||||
//! `votes[result_tag] += sum(staked_amount)` and everything else identical.
|
||||
//!
|
||||
//! From `Agora/Stake/Redeemers.hs` `ppermitVote` (~line 196):
|
||||
//!
|
||||
//! 8. Owner OR delegatee signs.
|
||||
//! 9. Single stake input (`pisSingleton # ctxF.stakeInputDatums`).
|
||||
//! 10. Output stake datum equals input with only `locked_by` mutated to
|
||||
//! `pcons NEW_LOCK old_locks`.
|
||||
//! 11. The new lock's `posix_time` is the **upper bound** of validity range
|
||||
//! (`PFullyBoundedTimeRange _ upperBound`).
|
||||
//!
|
||||
//! ## What's NOT in v1
|
||||
//!
|
||||
//! - **Multi-stake voting** — per the validator, `pfoldMap` over stakes
|
||||
//! means several stakes can chip in to clear the threshold. v1 supports
|
||||
//! single-stake votes only (matches the `pisSingleton` check on the
|
||||
//! stake side anyway). Multi-stake bundling lands in Phase 4b alongside
|
||||
//! cosign.
|
||||
//! - **Delegated voting (`delegatedTo`)** — handled by the validator
|
||||
//! (`pisSignedBy True` accepts the delegatee), but the builder
|
||||
//! currently doesn't expose a "vote on someone else's stake" arg. Add
|
||||
//! later if real users want it.
|
||||
//! - **Vote retraction** — `RetractVotes` redeemer path is its own builder
|
||||
//! (Phase 4 follow-up).
