Governor: enforce overridden settings and outcome rule, split into three traits - #973
Re-lands #938, which was reverted in #948 because there was not enough audit time to include it in the v0.8.0 stable release. The changes are identical to #938, rebased on current main.
Overrides of the Governor's trait methods were reported but not enforced: propose read the threshold, delay and period from storage, and queue, execute and cast_vote derived the proposal state again with hardcoded simple counting. This PR makes every default trait method take its inputs through Self::, so an override is what gets enforced, and splits the Governor into three traits along the same lines.
The default propose builds a ProposalSettings { threshold, voting_delay, voting_period } from Self::proposal_threshold, Self::voting_delay and Self::voting_period, and passes it to storage::propose, which no longer reads these values itself. A governor that overrides all three no longer needs to store placeholders.
get_token_contract is documented instead of changed: the token is set once by design, overriding the getter only changes the reported address, and the docs show how a contract that really needs to switch tokens can write its own setter (gated behind the governor's own authorization), along with the effect on live proposals.
GovernorQueries::proposal_state is now the single source of truth. storage::queue, storage::execute and storage::cast_vote take a state: ProposalState (computed by the caller through Self::proposal_state) instead of a quorum, and no longer derive the state themselves.
New hook GovernorQueries::proposal_succeeded decides whether a proposal passed. Its default checks the quorum (for + abstain >= Self::quorum) and the tally (for > against). Overriding it changes either criterion, e.g. a 60% rule or counting against votes toward the quorum, and the change is enforced by voting, queueing and execution alike.
storage::get_proposal_state takes the outcome as succeeded: bool instead of quorum.
The default proposal_state only calls proposal_succeeded once voting has ended and no state is recorded (checked with the new storage::outcome_pending). This saves the quorum and vote-count reads on every cast_vote, and a panicking outcome check can no longer block voting or reads of recorded states.
The quorum docs now state what the quorum does and does not control, and the misleading "pluggable counting" wording is replaced with the actual hooks.
Trait split
The Governor trait is split into three, each in its own module with its own mod.rs, storage.rs and test.rs:
All items are re-exported from governor, so governor::<item> paths like governor::set_quorum or governor::get_proposal_state keep working. governor::storage::<item> paths for the moved items do not (see breaking changes below). The contract interface gains one read-only function, proposal_succeeded. Every existing exported function keeps its name and signature.
GovernorStorageKey is split into GovernorSettingsStorageKey and ProposalStorageKey. Variant names are unchanged, and the enum name is not part of the encoded key, so an upgraded governor keeps reading its existing data (checked with a throwaway test comparing the XDR of both encodings).
Overrides of configuration methods (including proposals_need_queuing) move to the GovernorSettings impl.
Custom execute / queue pass Self::proposal_state(e, proposal_id) to storage::execute / storage::queue instead of Self::quorum(...).
storage::propose takes &ProposalSettings, storage::cast_vote takes a ProposalState, and storage::get_proposal_state takes succeeded: bool.
storage::check_proposal_state is removed; storage::cast_vote performs the Active check itself.
GovernorStorageKey is replaced by GovernorSettingsStorageKey and ProposalStorageKey.
governor::storage now holds only the lifecycle functions (propose, cast_vote, count_vote, queue, execute, cancel) and ProposalSettings. Everything else that used to live there (getters, setters, hash_proposal, ProposalCore, ProposalVoteCounts, QuorumCheckpoint, the VOTE_* constants and the counting helpers) moved to governor::queries::storage or governor::settings::storage, so governor::storage::<item> paths for them no longer compile. Use governor::<item> instead, e.g. governor::hash_proposal in place of governor::storage::hash_proposal.
Both governor examples are updated accordingly.
PR Checklist
Tests: existing tests moved to the module they exercise; new tests cover overridden threshold, delay and period being enforced (and no stored placeholders needed), a two-thirds rule through proposal_succeeded (defeated at 60/40 and rejected by queue, queued and executed at 70/30), the same rule through a proposal_state override (rejected by execute), counting against votes toward the quorum, cast_vote following the reported state, and a panicking proposal_succeeded blocking neither voting nor reads of recorded states.

New Features
Governance contracts now provide separate settings and proposal-query capabilities, including proposal status, voting deadlines, proposer details, vote totals, and voting records.
Governance settings can be customized, including quorum, proposal thresholds, voting periods, and whether successful proposals require queueing.
Proposal outcomes use quorum participation and vote tallies; quorum changes are tracked over time.
Documentation
Updated governance guidance to explain configurable settings, proposal outcomes, and default vote counting.

Walkthrough
The governor API now separates settings, read-only proposal queries, and lifecycle operations. Proposal creation uses configured settings, while voting, queueing, and execution use the reported proposal state. Example contracts, tests, and documentation are updated to use the split traits and state flow.

Summary
Settings trait and checkpoint storage packages/governance/src/governor/mod.rs, packages/governance/src/governor/settings/*
GovernorSettings owns configuration getters and the queueing setting. Settings storage adds configuration accessors and ledger-indexed quorum checkpoints.
Proposal queries and state derivation packages/governance/src/governor/queries/*
GovernorQueries adds proposal queries and default success and state rules. Query storage handles proposal data, vote counts, quorum, tally, and state derivation.
Lifecycle state and settings integration packages/governance/src/governor/mod.rs, packages/governance/src/governor/storage.rs, packages/governance/src/governor/test.rs
Proposal creation passes threshold and voting schedule settings to storage. Voting, queueing, and execution pass proposal state to storage. Tests cover settings and outcome overrides.
Contract examples and usage documentation examples/fungible-governor/governor/src/governor.rs, examples/fungible-governor-timelock/governor/src/governor.rs, packages/governance/README.md
Example contracts implement the settings and query traits separately and pass proposal state to queue and execute. The README describes the trait split and success-rule override.
OpenZeppelin/stellar-contracts#961: Also changes governor outcome hooks and passes proposal state to voting, queueing, and execution storage functions.
This PR makes overridden governor settings and custom outcome rules take effect throughout the proposal lifecycle. No merge-blocking risk was found. One README sentence should say that overriding the voting-token getter does not change the token used for enforcement.

Explanation
The title names the two main changes: enforcing overridden settings and the outcome rule, and splitting the Governor into three traits. The raw summary and objectives confirm both changes, including the GovernorSettings, GovernorQueries and Governor split and the routing of propose, queue, execute and cast_vote through overridable methods. The title is specific and accurate, though at 79 characters it is slightly long.
Full details: Linked Issues check
Explanation
[#936] The default propose in packages/governance/src/governor/mod.rs builds ProposalSettings from Self::proposal_threshold, Self::voting_delay and Self::voting_period, then calls storage::propose with &settings. The storage layer does not read these values, so overrides are enforced and no stored placeholder is required. The get_token_contract docs in settings/mod.rs state that the token is set once, that overriding the getter changes only the reported address, and that a custom setter gated by require_auth can switch tokens. They also describe the effect on live proposals. This matches the documentation-only requirement in #936.
[#937] GovernorQueries::proposal_state in queries/mod.rs is the single state source. Governor::cast_vote calls Self::proposal_state, and storage::cast_vote, storage::queue and storage::execute take a state: ProposalState instead of a quorum. The default proposal_succeeded hook checks quorum at the proposal snapshot and the for > against tally. Its docs include a 60% override example. An override of proposal_succeeded therefore applies to voting, queueing and execution. A defeated outcome blocks queue and execute. The quorum and README docs now describe the actual hooks.
Residual uncertainty: the default bodies of Governor::queue and Governor::execute in governor/mod.rs were truncated in the read. Their use of Self::proposal_state rests on the PR description, the documented queue override pattern, and the storage-level signatures. Tests named in the PR description were not executed during this review.
Full details: Out of Scope Changes check
Explanation
The trait split (GovernorSettings, GovernorQueries, Governor), the storage module split, and the GovernorStorageKey split are the structure that the PR objectives name for #936 and #937. The split moves settings reads and state derivation into the traits that enforce them. Public paths stay available through re-exports in governor/mod.rs, including emit_quorum_changed, get_proposal_state and the other settings and query items. The removed storage::check_proposal_state is replaced by the Active check in storage::cast_vote, which follows from the state-passing design. Both governor examples and the README are updated to match the new traits, as the objectives require. The storage key rename keeps variant names, and the PR reports an XDR check showing unchanged encoded keys; that check was not re-run here. No unrelated behavior change was identified. The breaking changes are large but are declared in the PR description and follow from the requested design. Scope judgment rests on the summaries and the files read. The truncated governor/mod.rs body and the full diff were not read in full.

packages/governance/src/governor/storage.rs:130 — propose now takes voting_period from Self::voting_period, but only set_voting_period rejects zero. An override that returns 0, for example one computed from a parameter that is still 0, sets vote_end == vote_snapshot. Every proposal then goes from Pending straight to Defeated and never accepts a vote. If that parameter can only change through a passed proposal, the governor cannot recover. This is the case InvalidVotingPeriod was added to prevent, and before this PR the setter's check covered every enforced value. Reject settings.voting_period == 0 with GovernorError::InvalidVotingPeriod in storage::propose, and add a test with an override that returns 0.
packages/governance/src/governor/mod.rs:166 — moving the getters, setters, hash_proposal, ProposalCore and the counting helpers out of governor::storage breaks every governor::storage::<item> path. The cancel example on main used two of them (storage::hash_proposal, storage::get_proposal_proposer). The description says existing paths keep working, but it only covers the governor::<item> re-exports, and its breaking-changes list leaves this out. Re-export the moved items from governor::storage as well, or list the removed governor::storage::* paths under breaking changes.
packages/governance/src/governor/queries/storage.rs:19, packages/governance/src/governor/settings/storage.rs:18 — the split of GovernorStorageKey into two enums relies on unchanged variant names so that an upgraded governor still reads its old entries. Per the description, this was checked only by a throwaway test. Commit that check: write the entries with a test copy of the old GovernorStorageKey, then read them back through get_proposal_core, get_quorum and get_token_contract. A later rename would otherwise orphan live proposals and settings with no failing test.
packages/governance/src/governor/queries/storage.rs:163 — outcome_pending counts only a stored Pending as "no state recorded", but derive_proposal_state (line 378) treats every state except Canceled, Executed, Queued and Expired as derived. For a stored Succeeded, which the ProposalState docs describe as "set by the counting logic", the default proposal_state now skips proposal_succeeded and returns Defeated after vote_end. Before this PR it recomputed the outcome. Base both functions on one predicate for recorded states.
packages/governance/src/governor/settings/mod.rs:21, packages/governance/README.md:50 — both say that an overridden setting is what gets enforced. The get_token_contract docs in the same trait say the opposite, and get_voting_power reads the stored token. Name get_token_contract as the exception in both places.
Other doc lines this PR made inaccurate: packages/governance/src/governor/settings/mod.rs:180-186 says quorum is called during Pending and must not panic on future ledgers, but the default proposal_state now calls it only after vote_end. packages/governance/src/governor/mod.rs:136 and :151 point to the stored getters get_proposal_threshold() and get_voting_delay() as the enforced values, where GovernorSettings::proposal_threshold and GovernorSettings::voting_delay are now.

packages/governance/src/governor/storage.rs:130 — propose now takes voting_period from Self::voting_period, but only set_voting_period rejects zero. [...] Reject settings.voting_period == 0 with GovernorError::InvalidVotingPeriod in storage::propose, and add a test with an override that returns 0.
An override returning 0 is a bug in the integrator's override, and a check in propose would not let the governor recover. propose would panic with InvalidVotingPeriod, so no proposal could be created, which locks the governor just as much. The library trusts overrides elsewhere (proposal_state, proposal_succeeded, quorum), so we documented the requirement on voting_period instead of adding a check.
- Document that get_token_contract is the one setting whose override is
not enforced, and that it is not meant to be overridden.
- Document that a voting_period override must return a non-zero value.
- Correct the ProposalState docs: Succeeded and Defeated are derived,
never stored; Queued is stored by Governor::queue.
- Update the quorum docs to the new call pattern (only after vote_end).
- Point the security notes to the GovernorSettings methods.
- Add a storage-key compatibility test for the GovernorStorageKey split.
Replies to the remaining items, addressed in e4079e9:
packages/governance/src/governor/mod.rs:166: moving the getters, setters, hash_proposal, ProposalCore and the counting helpers out of governor::storage breaks every governor::storage::<item> path.
We kept the code as is and updated the PR description instead. The "paths keep working" sentence now covers only governor::<item> paths, and the breaking-changes list says that governor::storage holds only the lifecycle functions and ProposalSettings, with governor::<item> as the replacement path for everything else. Re-exporting ~30 items from governor::storage would make each item reachable three ways, and this release already breaks the storage API elsewhere.
packages/governance/src/governor/queries/storage.rs:19, packages/governance/src/governor/settings/storage.rs:18: commit the storage-key check.
Added as storage_key_compatibility in governor/test.rs. It writes one entry per variant of a copy of the old GovernorStorageKey (all 11, in the storage tier the library uses for each) and reads every one back through the current getters.
packages/governance/src/governor/queries/storage.rs:163: outcome_pending counts only a stored Pending as "no state recorded", but derive_proposal_state treats every state except Canceled, Executed, Queued and Expired as derived.
Succeeded and Defeated are never stored. No transaction runs when voting ends, and after that the vote counts and the quorum can't change, so they are always computed. The library only stores Pending, Queued, Executed and Canceled (plus Expired from extensions), and the two functions agree on all of them. The ProposalState docs that said Succeeded is set by the counting logic were wrong; they are fixed now (they also wrongly attributed Queued to extensions).
packages/governance/src/governor/settings/mod.rs:21, packages/governance/README.md:50: name get_token_contract as the exception.
Done in both places. The token is set once by design, so overriding the getter only changes the reported address, and its docs now say it isn't meant to be overridden.
Other doc lines this PR made inaccurate: settings/mod.rs:180-186 (quorum), mod.rs:136 and :151.
Fixed both: the quorum docs now say the default path calls it only after vote_end (only a custom proposal_state or proposal_succeeded can pass a future ledger), and the security notes point to GovernorSettings::proposal_threshold and GovernorSettings::voting_delay.
packages/governance/src/governor/settings/mod.rs:72-87 — this PR adds the token-switch recipe for #936. It gates update_token_contract with e.current_contract_address().require_auth() and says that "a switch can only happen through a passed proposal". That path cannot work. A passed proposal runs from inside the governor's execute: storage::execute calls e.invoke_contract on each target. If the target is the governor itself, Soroban rejects the call as contract re-entry (examples/timelock-controller/src/contract.rs:91-96 documents this limit). A direct outside call fails too, because the governor has no __check_auth to satisfy its own require_auth. An integrator who copies the recipe gets a setter that nothing can call, and finds out only when governance tries to switch the token. Gate the example on an address that can call the governor directly, such as the timelock (with the operation targeting the governor) or an #[only_role] role. Alternatively, state that self-gated setters are unreachable. Add a test that runs the recommended pattern from a proposal.
Checked: 8 product files, 3 test files. Not run: reproduction (the caller does not allow cargo or writing test files in this run), network-limits.sh (the PR adds no caller-supplied collections). Unavailable: openzeppelin-platform.
packages/governance/src/governor/storage.rs:337-342, :397-409 — queue and execute load the proposal record but now check only the state the caller passes. They never look at proposal.state. Before this PR they derived the state from that record, so a stored Executed or Canceled always blocked them. Now that protection depends on every proposal_state override returning recorded states unchanged. Picture an override that follows the outcome_pending guidance loosely and decides the outcome from the ledger alone (sequence > deadline → Succeeded). It reports an executed proposal as Succeeded again. With the documented open-execution execute, anyone can then run its actions a second time, for example a treasury transfer. The same mistake lets queue turn a Canceled proposal back into Queued. storage::cancel (line 477) already checks the stored state it loads. Do the same here at no extra read cost: queue should require a stored Pending, and execute should require a stored Pending, or Queued when queueing is on. Reject anything else with the existing errors, and add a test with an override that misreports a recorded state.
packages/governance/src/governor/mod.rs:194-197 — the new Governor trait doc says every default method reads its configuration from GovernorSettings, "so overrides of either are respected". propose and cast_vote weigh votes with the stored token (get_voting_power reads settings::storage::get_token_contract), so an overridden get_token_contract is not respected. The PR names this exception in settings/mod.rs:24-27 and the README, but this third statement leaves it out. Name get_token_contract as the exception here too.
Checked: 8 product files, 3 test files. Not run: reproduction and cargo commands (the caller does not allow them), network-limits.sh (the PR adds no caller-supplied collections). Unavailable: openzeppelin-platform.
@catalina-oz This is intentional: storage::queue and storage::execute trust the state passed to them, which must come from proposal_state. The override contract on GovernorQueries::proposal_state already requires recorded states to be returned unchanged, and names this exact case (reporting an Executed proposal as Succeeded would allow it to be executed again). We don't add checks to the library to guard against overrides that break their documented contract.
packages/governance/src/governor/queries/mod.rs:79-90 — the documented 60% proposal_succeeded override lets a proposal pass with no for votes at all. When only abstain votes reach the quorum, for and against are both 0, so for_share (0) >= required_share (0) is true and the proposal is Succeeded. The default rule rejects this case (for > against, and proposal_with_only_abstain_votes_not_succeeded tests it). An integrator who copies the example gets a governor that executes a proposal, such as a treasury transfer, that nobody voted for. The test helper two_thirds_in_favor (packages/governance/src/governor/test.rs:1567-1570) has the same gap, so the PR's tests cannot catch it. Treat for + against == 0 as not passed in the example and the helper, for example by also requiring counts.for_votes > 0. Add a test where only abstain votes reach the quorum under the custom rule and check that the proposal is Defeated.
packages/governance/src/governor/queries/mod.rs:65, :111 — this PR exports proposal_succeeded as a new read-only contract function and documents it as "Returns whether a proposal passed its vote". The default body only checks the quorum and the tally. It ignores the voting window and any recorded state. It returns the running tally while voting is still Active, and returns true for a Canceled proposal that had enough votes. A UI or another contract that calls it reads "passed" for proposals that have not passed and cannot be executed. State in the doc that the result only means something once voting has ended and no state is recorded (outcome_pending), and that proposal_state gives the status.
packages/governance/src/governor/settings/mod.rs:17-18 — the new trait doc says every method's default "returns the value stored with the matching setter". counting_mode and proposals_need_queuing have no setter and return the constants "simple" and false. Name these two as exceptions.
