Build a `dao_proposal_retract_votes` transaction. +//! +//! Retract one stake's locks for a given proposal. Pairs with the proposal +//! being spent under `UnlockStake`. Two distinct effects depending on the +//! proposal's current status: +//! +//! - **Proposal in `VotingReady` (and within voting window)**: removes the +//! stake's `Voted` lock for that proposal AND subtracts the stake's +//! `staked_amount` from `proposal.votes[voted_tag]`. Stake's +//! `Created`/`Cosigned` locks for that proposal are kept. +//! - **Proposal in `Finished`**: removes ALL locks for that proposal_id +//! (Voted + Created + Cosigned). Proposal datum is unchanged. This is the +//! path that finally lets a stake become unlocked + destroyable after a +//! proposal has resolved. +//! - **Proposal in any other status / outside voting window**: removes only +//! `Voted` locks, AND only if the lock's cooldown has elapsed +//! (`createdAt + minStakeVotingTime ≤ tx_lower_ms`). Proposal datum is +//! unchanged. Useful for unlocking a stake on a `Locked` proposal whose +//! voting closed but isn't fully `Finished` yet. +//! +//! ## Tx shape +//! +//! - **Inputs**: +//! - The voter's stake UTxO (Plutus spend, redeemer = `RetractVotes`). +//! - The target proposal UTxO (Plutus spend, redeemer = `UnlockStake`). +//! - One ada-only wallet UTxO for funding. +//! - **Collateral input**: separate ada-only ≥5 ADA wallet UTxO. +//! - **Reference inputs**: +//! - Stake validator script. +//! - Proposal validator script. +//! - **No mints**. +//! - **Outputs**: +//! - New stake UTxO at `stakes_addr`. Datum = old StakeDatum with +//! `locked_by` filtered per the rules above. StakeST + gov-token qty +//! preserved. +//! - New proposal UTxO at `proposal_addr`. Datum is either: +//! - votes-mutated copy of input datum (only if VotingReady + in +//! voting window — matches `shouldUpdateVotes` in `Agora/Proposal/ +//! Scripts.hs:601-611`), +//! - or bit-identical copy of input datum (every other case). +//! ProposalST preserved. +//! - Wallet change. +//! +//! ## What the validator enforces (must match) +//! +//! From `Agora/Stake/Redeemers.hs:326` `pretractVote`: +//! +//! 1. ProposalContext is `PSpendProposal proposal UnlockStake currentTime` +//! — i.e. the same tx must spend a proposal under UnlockStake. +//! 2. Owner OR delegatee signs. +//! 3. Output stake datum equals input with only `locked_by` mutated to the +//! filtered list. +//! 4. Filter rule (per `premoveLocks` at `Stake/Redeemers.hs:284`): +//! - Voted lock for proposal_id: removed iff +//! `(mode = RemoveAllLocks)` OR +//! `(createdAt + minStakeVotingTime ≤ lowerBound)`. +//! If not in either case, validator errors. +//! - Created/Cosigned lock for proposal_id: removed iff +//! `mode = RemoveAllLocks`. +//! - Mode = `RemoveAllLocks` if proposal is `Finished`, else +//! `RemoveVoterLockOnly`. +//! +//! From `Agora/Proposal/Scripts.hs:569` `PUnlockStake` branch: +//! +//! 5. Every spent stake input must have `locked_by` containing at least one +//! lock for this proposal_id (i.e. `pgetStakeRoles` must NOT return +//! `PIrrelevant`). Pre-flighted client-side. +//! 6. If `currentStatus == VotingReady && tx-validity inside voting period`: +//! proposal output votes = `pretractVotes` over input stakes (subtract +//! each voter stake's amount from its voted tag). Other proposal fields +//! bit-identical. +//! 7. Otherwise: proposal output = bit-identical copy of input. +//! 8. Validity range width ≤ `votingTimeRangeMaxWidth`. +//! +//! ## What's NOT in v1 +//! +//! - **Multi-stake retraction** — `pretractVotes` over multiple stakes is +//! what the proposal validator supports; v1 supports a single stake to +//! match the rest of our builder family. +//! - **Selecting which lock to retract when a stake has multiple voted +//! locks for the same proposal_id** — that shouldn't happen (the voter +//! path prevents double-vote), but if it ever does, we retract all of +//! them together. + +use pallas_codec::minicbor; +use pallas_crypto::hash::Hash; +use pallas_txbuilder::{BuildConway, Input, Output, ScriptKind, StagingTransaction}; + +use crate::agora::proposal::{ProposalDatum, ProposalRedeemer, ProposalStatus, ProposalVotes}; +use crate::agora::stake::{Credential, ProposalAction, ProposalLock, StakeDatum, StakeRedeemer}; +use crate::config::{DaoConfig, DaoNetwork}; +use crate::error::{DaoError, DaoResult}; + +use super::proposal_create::{ + parse_address, parse_script_hash, parse_tx_hash, ReferenceUtxo, StakeUtxoIn, WalletUtxo, + MIN_COLLATERAL_LOVELACE, PROPOSAL_CREATE_SPEND_EX_UNITS as RETRACT_SPEND_EX_UNITS, + SCRIPT_OUTPUT_MIN_LOVELACE, VALIDITY_RANGE_SLOTS, +}; +use super::proposal_vote::ProposalUtxoIn; + +/// Wallet-change min-UTxO floor.

Build a `dao_proposal_vote` transaction. +//! +//! This is the second DAO write path.

Datum = old StakeDatum with a +//! fresh `Voted { result_tag, posix_time = validity_upper_ms }` +//! lock **prepended** to `locked_by` (per Agora's `paddNewLock = pcons`). +//!

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.

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 +//!
