Issue being fixed or feature implemented

Part of the decentralized moderation teams design (#4865): the election parameters of the vote poll precursor. Closes #4876.

A charter application is an electedCharter create on the moderation charters contract (#4898), on a contested unique index keyed by the target contract id and resolved without locking (#4907). Until now that contest ran on the generic contested-document parameters: the DPNS join window and poll duration from the version tables (one week and two weeks on mainnet, 45 and 90 minutes on test networks) and the 0.1 Dash contested document fund. The design says an election runs on the join and vote windows the target contract declares in its elected moderation declaration, and that applying costs 0.5 Dash.

What was done?

Windows from the target contract. A new Drive method, fetch_charter_election_windows, recognizes a moderation election (a contest on the charter contract's electedCharter type), takes the target contract id from the contest's one index value, reads the target (billed with the FeeResult that read returns, never the cached fee of a DataContractFetchInfo) and returns its joinWindow and joinWindow + voteWindow in milliseconds. Every other contest is answered with None without a read. Its version slot is insert_contested.fetch_charter_election_windows: OptionalFeatureVersion, None in every document method table before protocol version 14 and Some(0) in DRIVE_DOCUMENT_METHOD_VERSIONS_V4.

Two places read it:

add_contested_document_for_contract_operations v1 (protocol version 14 only): the end date written when the contest opens (join window end for a no-lock contest), and the move to join plus vote window when the second applicant joins. The feat(platform)!: contested indexes resolved without locking, ties to the earliest contender (moderation teams A1) #4907 single-contender end and moving end are reused; the durations change, and the move now looks up the join-window entry it recomputed (a billed read) and leaves the end where it is when the entry is not there, instead of failing to delete a missing key. Fee estimation, which reads nothing, now counts the target read as a read of a contract at estimated_contract_max_serialized_size.
Document create state validation, the join check (DocumentContestNotJoinableError): a late applicant is refused against the target's join window, and the error names it.

ContestWindows::generic(network, platform_version) now holds the per-network generic windows both of them fall back to.

The target's windows apply on every network: a declaration has no test-network variant, so a charter election on testnet also lasts at least a day.

Before (any network, an elected target declaring joinWindow: 86400, one applicant):

end date of the contest = start + allow_other_contenders_time   (mainnet: + 1 week, testnet: + 45 minutes)

After:

end date of the contest = start + 1 day
second applicant within the day -> end = start + joinWindow + voteWindow

Before (target declaring joinWindow: 2419200, four weeks; a second applicant two weeks in):

DocumentContestNotJoinableError: ... and you can only join for 604800000

After:

accepted; the contest ends at start + 4 weeks + voteWindow
an applicant after four weeks: DocumentContestNotJoinableError ... you can only join for 2419200000

The fund. VoteResolutionFundFees gains moderation_vote_resolution_fund_required_amount, the prefunded voting balance of a moderation poll (the application now; challenges and amendments later). It is 0.5 Dash in VOTE_RESOLUTION_FUND_FEES_VERSION2 (protocol version 14, inside FEE_VERSION3, amended in place since 14 owns that schedule): 25,000 votes at the protocol version 14 vote cost of 0.00002 Dash (#4959), up from the 5,000 the design noted at the old 0.0001 Dash price. VOTE_RESOLUTION_FUND_FEES_VERSION1 (protocol versions 1 to 13) carries the contested document amount, 0.2 Dash, in the new field, so a shipped path choosing between the two funds charges exactly what it did; a test in v14.rs pins that equality for every protocol version before 14.

required_vote_resolution_fund(contract_id, document_type_name, platform_version) in rs-dpp is the one place that picks the fund, and is_charter_election / charter_election_target in dpp::moderation_charter the one definition of a moderation election. The create structure check (advanced structure v1, protocol version 14 only) and the client helper prefunded_voting_balance_for_document both use it, so SDKs building an electedCharter create through DocumentCreateTransition::from_document put 0.5 Dash in it with no client change. The remainder is released as processing fees by the existing clean_up_after_contested_resources_vote_polls_end v1.

Before (an electedCharter create prefunding 0.5 Dash):

DocumentContestNotPaidForError: expected 10000000000, paid 50000000000

After:

accepted; 0.5 Dash moves to the contest's prefunded balance
prefunding 0.1 Dash -> DocumentContestNotPaidForError: expected 50000000000, paid 10000000000

A DPNS contest still requires and holds 0.1 Dash per contender and still ends after the generic poll duration.

Totality. Nothing at the end of a contest reads the target: its end date was written when the contest opened or was joined. A target that is missing, or that declares something other than elected moderation, gives no windows: the join check then applies no join limit to that election, so the application's own refersTo validation, which follows, refuses it with the error that says why (40120 or 40135) on every network. Neither can happen today (contracts are not deletable and the elected declaration is frozen at creation), and the tests force both.

One poll per contest, whatever form the identifier takes. Validation accepts an identifier property as an identifier, as 32 bytes or as an array of byte values, and the contested index keys store all three alike, but a poll is hashed from its raw index values, and that hash keys the prefunded balance and the end-date entry. From protocol version 14, Index::extract_contested_values writes identifier-typed index values as Value::Identifier (new slot canonical_contested_index_values, None before 14, Some(0) in CONTRACT_VERSIONS_V6); the create action transformer and contested_vote_poll_for_document_properties use it. charter_election_target reads every accepted identifier form.

Before (protocol version 14 without this, target joinWindow: 86400):

application with targetContractId as [u8; 32] integer array -> contest ends at start + 45 minutes (generic)
first applicant Identifier, second Bytes -> two polls, two 0.5 Dash balances, end stays at start + 1 day

After:

both -> one poll keyed by Value::Identifier; ends at start + 1 day, or start + 8 days once a second applicant joins

Frozen decoding. FeeVersionFieldsBeforeVersion4, the pre-1.4 platform state format, embedded VoteResolutionFundFees; it now embeds VoteResolutionFundFeesFieldsBeforeVersion4, the three fields exactly as before, so old saved states keep decoding. Same pattern as FeeStorageVersionFieldsBeforeVersion4.

Docs: docs/protocol/moderation-charters.md (the contest section), the book's contested documents chapter (a moderation elections section) and the fee overview (a contest funds table).

In-place changes to shipped generations

Document create state validation v1 (document_create_transition_action/state_v1), selected directly by protocol versions 2 to 13 (and called by v2 at 14). The join window now comes from fetch_charter_election_windows when it answers Some; a moderation election whose target gives none (the target was read, so a fee came back) gets no join limit; otherwise the generic window as before, now through ContestWindows::generic(platform.config.network, ..), which returns the same table values for the same network. The method's version slot is None in every table of protocol versions 1 to 13, where the dispatcher returns (None, None) without reading or billing, so those versions take the generic window, the same fee and the same error. should_refuse_joining_a_contest_after_the_join_window_protocol_version_13 runs the unchanged refusal at 13, and should_read_nothing_before_protocol_version_14 pins the dispatcher.
prefunded_voting_balance_for_document v0 (rs-dpp, every protocol version; builds transitions, no validator reads it). The amount now comes from required_vote_resolution_fund. For protocol versions 1 to 13 both funds are 0.2 Dash, pinned by should_change_only_the_contested_document_and_once_per_identity_fees_at_protocol_14, so the output is identical.
VOTE_RESOLUTION_FUND_FEES_VERSION1 (protocol versions 1 to 13) gains the new field, set to the contested document amount (backfill; no reader before 14).
FeeVersionFieldsBeforeVersion4: field type swapped for a struct with the same three fields in the same order; the wire format is unchanged.
DRIVE_DOCUMENT_METHOD_VERSIONS_V1 to V3 gain fetch_charter_election_windows: None.
Document create action transformer (document_create_transition_action/v0/transformer.rs, not versioned, every protocol version) and contested_vote_poll_for_document_properties v0 (rs-dpp, every protocol version): both now build a contest's index values with Index::extract_contested_values. Its slot canonical_contested_index_values is None in CONTRACT_VERSIONS_V1 to V5 (protocol versions 1 to 13), where it returns extract_values unchanged, so the polls, their hashes and the balances they key are identical there. The dpp test should_write_identifier_contest_values_as_identifiers_from_version_14 runs it at 13 and 14.
CONTRACT_VERSIONS_V1 to V5 gain canonical_contested_index_values: None.

Protocol version 14 only, edited in place: add_contested_document_for_contract_operations v1, create advanced structure v1, VOTE_RESOLUTION_FUND_FEES_VERSION2, DRIVE_DOCUMENT_METHOD_VERSIONS_V4, CONTRACT_VERSIONS_V6.

How Has This Been Tested?

drive-abci end to end, through process_raw_state_transitions against the genesis moderation charters contract (masternode_vote/charter_election_tests.rs):

should_award_a_single_applicant_when_the_target_join_window_closes
should_move_the_end_to_the_join_and_vote_windows_when_a_second_applicant_joins (joins two weeks in, past every generic join window; a late applicant is refused naming the four-week window; plurality at the vote end)
should_end_elections_of_targets_with_different_windows_at_different_heights
should_prefund_each_application_with_half_a_dash_and_release_the_remainder_at_clean_up (balance drop = 0.5 Dash + the document fee; the prefunded balance holds 0.5 Dash per applicant; three votes; after clean-up the balance is empty and the epoch's processing credits rose by the remainder)
should_keep_the_generic_windows_and_fund_for_a_dpns_contest
should_end_an_election_whose_target_changed_kind, should_end_an_election_whose_target_disappeared (the target rewritten without moderation, or its stored contract removed; an applicant two hours in, past the 45-minute generic window of test networks, gets 40135 or 40120, not a join-window error and not an internal one; the election still ends and awards)
should_keep_the_end_date_when_the_windows_changed_during_an_election (the target's windows rewritten mid-election: the second applicant is admitted, the contest keeps the end it opened with, nothing fails)
should_honor_the_target_windows_of_an_application_writing_the_target_as_an_array, should_move_the_end_when_applicants_write_the_target_in_different_forms (both fail with canonical_contested_index_values switched off)

drive-abci unit (create advanced structure v1): should_require_the_moderation_fund_of_a_charter_application, should_construct_charter_applications_with_the_moderation_fund, and the PV13 join window twin above.

drive (fetch_charter_election_windows): should_read_the_windows_of_an_elected_target_and_bill_the_read, should_answer_every_other_contest_without_a_read, should_leave_a_missing_or_unelected_target_on_the_generic_windows, should_read_nothing_before_protocol_version_14.

dpp: should_read_a_charter_election_target_from_every_accepted_identifier_form (identifier, 32 bytes, an array of byte values; base58 text, a non-byte array and a short byte string name no target) and should_write_identifier_contest_values_as_identifiers_from_version_14.

drive (contested insert v1): should_estimate_the_target_read_of_a_moderation_election_whatever_the_state (the estimate equals the average-case read of the target's contract item at estimated_contract_max_serialized_size, stored or absent; no read for a non-charter contest).

platform-version: the frozen three-field decoding (decodes a plain (u64, u64, u64) encoding, so a field added to the frozen struct fails it) and the updated protocol version 14 fee pin.

Run locally (after merging the latest v4.2-dev, which also fixes the unrelated moderation-charters-contract schema test that failed CI):

cargo test -p platform-version --lib: 23 passed.
cargo test -p dpp --lib filtered to contested, vote_poll, prefunded: 80 passed; moderation_charter::tests and the canonicalizer test: 13 passed.
cargo test -p drive --lib filtered to fetch_charter_election_windows and the estimate test: 5 passed.
cargo test -p drive-abci --lib filtered to masternode_vote, advanced_structure_v1, contested, dpns and the join-window tests: 153 passed (10 charter election tests among them).
cargo fmt --all. cargo clippy -p platform-version -p dpp -p drive -p drive-abci --all-features --all-targets -- -D warnings: clean.

Breaking Changes

Consensus at protocol version 14 (unreleased): an electedCharter create must prefund 0.5 Dash instead of 0.1 Dash, a charter election's end date and join limit follow the target contract's declaration, and identifier index values of every contest are written as identifiers in its poll (a masternode vote naming such a poll with bytes instead of an identifier finds no prefunded balance). Nothing changes for protocol versions 1 to 13. VoteResolutionFundFees has a new public field, so code building one with a struct literal must set it.

Summary by CodeRabbit

New Features
- Moderation-charter elections now follow the target contract’s join and voting windows. Applicants prefund votes, and unused funds are released as processing fees when the contest ends.
- Contested documents accept identifier values in multiple formats while consistently grouping equivalent values into the same contest from protocol version 14.
- Added documentation on contest funding, moderation elections, and identifier handling.

…and a 0.5 Dash fund (PV14) An electedCharter contest of the moderation charters contract now runs on the join window and vote window of its target contract's elected moderation declaration, on every network, and each application prefunds the masternode votes with the new moderation fund (0.5 Dash) instead of the 0.1 Dash contested document fund. Every other contest, DPNS included, keeps the generic windows and fund. - VoteResolutionFundFees gains moderation_vote_resolution_fund_required_amount: 0.5 Dash in VOTE_RESOLUTION_FUND_FEES_VERSION2 (PV14), the contested amount in VERSION1 so shipped paths charge what they did. The pre-1.4 platform state decoder keeps a frozen three-field struct. - dpp: is_charter_election / charter_election_target and required_vote_resolution_fund, used by the PV14 create structure check and by prefunded_voting_balance_for_document (clients). - drive: fetch_charter_election_windows (optional slot, None before 14) reads the target and bills the read; add_contested_document_for_contract_operations v1 uses it for the end date and the move on the second applicant. - drive-abci: the create join check reads the target's join window (state v1 in place: the helper answers None before 14). - A missing or non-elected target falls back to the generic windows; nothing at the end of a contest reads the target.

📝 Walkthrough

Walkthrough

Protocol v14 adds target-declared join and vote windows and a moderation-specific prefunding amount for elected-charter contests. The change also normalizes identifier index values and updates fee schedules, validation, poll processing, tests, and documentation.

Changes

Moderation-charter elections

Layer / File(s)	Summary
Contest identity and fund selection `packages/rs-dpp/src/data_contract/document_type/index/mod.rs`, `packages/rs-dpp/src/moderation_charter/`, `packages/rs-dpp/src/voting/vote_polls/contested_document_resource_vote_poll/mod.rs`, `packages/rs-dpp/src/data_contract/document_type/methods/`, `packages/rs-platform-version/src/version/fee/*`, `packages/rs-drive-abci/src/execution/validation/state_transition/.../document_create_transition_action/advanced_structure_v1/mod.rs`	Protocol v14 canonicalizes identifier values in contested indexes. Elected-charter contests select the moderation vote-resolution fund. Fee configuration preserves older fee encodings, and document prefunding validation uses the selected amount.
Resolve target-declared poll windows `packages/rs-platform-version/src/version/drive_versions/drive_document_method_versions/`, `packages/rs-drive/src/drive/document/insert_contested/fetch_charter_election_windows/`, `packages/rs-drive/src/drive/contract/contract_fetch_info.rs`, `packages/rs-drive/src/drive/document/mod.rs`	Drive identifies the target contract for an elected-charter contest, reads its elected-moderation declaration, and converts its join and vote windows to milliseconds. The lookup is configured for protocol v14.
Apply windows and verify contest behavior `packages/rs-drive/src/drive/document/insert_contested/add_contested_document_for_contract_operations/v1/mod.rs`, `packages/rs-drive-abci/src/execution/validation/state_transition/.../document_create_transition_action/`, `packages/rs-drive-abci/src/execution/validation/state_transition/state_transitions/masternode_vote/`, `packages/rs-dpp/src/data_contract/document_type/index/mod.rs`, `book/src/data-model/contested-documents.md`, `book/src/fees/overview.md`, `docs/protocol/moderation-charters.md`	Contest creation and joining use target windows when returned, and generic windows otherwise. Tests cover deadlines, second applicants, funding and cleanup, target changes, identifier forms, generic DPNS behavior, and protocol v13. Documentation describes the windows and fund selection.

Explanation

The PR implements target-contract windows, the 0.5 Dash moderation fund, cleanup credit release, protocol gating, identifier canonicalization, and DPNS coverage [#4876]. The protocol-14 fee table sets moderation_vote_resolution_fund_required_amount to 50,000,000,000 credits and contested_document_single_vote_cost to 2,000,000 credits. This balance supports 25,000 vote deductions, not 5,000. The 5,001st vote is therefore not refused by fund exhaustion. The same vote-cost change also does not preserve the prior per-vote amount for generic contests.

Resolution

Configure the moderation poll funding and vote-cost enforcement so 0.5 Dash supports exactly 5,000 votes and the 5,001st vote is refused. Preserve the prior generic contest vote amount. Add regression tests for both vote boundaries and the DPNS path.

…stimate the target read Review fixes for the charter election parameters: - The second applicant's move looks up the join-window entry it recomputed and leaves the end date where it is when the entry is not there, instead of failing to delete a missing key. - The create join check applies no join limit to a moderation election whose target gives no windows, so the reference validation that follows refuses it with 40120/40135 on every network. - Fee estimation counts the target read as a contract read at estimated_contract_max_serialized_size. - ContestWindows::generic holds the per-network generic windows. - charter_election_target reads only 32-byte forms (no base58 text or integer arrays). - The frozen pre-1.4 decoder test decodes a plain three-u64 encoding; the PV13 twin test starts with "should"; version table docs name the new slot.

Final validation — Phase 2 only (queue backlog)

Two identifier-representation defects prevent charter elections from reliably honoring the target contract's declared windows. Both were independently reproduced through process_raw_state_transitions: an integer-array target used the generic 45-minute window, and mixed Identifier/Bytes applicants left an eight-day election ending after one day. All eight existing charter-election tests passed; the new stateless target-read estimate also lacks a focused regression assertion.

Triage: critical by gpt-6-astra (effort low) — The diff intricately changes consensus-critical contest timing and admission in add_contested_document_for_contract_operations/v1 and document_create_transition_action/state_v1, alongside moderation fund charging and protocol-version gating across DPP, Drive, and Drive ABCI.

In `packages/rs-dpp/src/moderation_charter/mod.rs`:
- [BLOCKING] packages/rs-dpp/src/moderation_charter/mod.rs:87-90: Honor target windows for schema-valid integer-array identifiers
  An electedCharter can supply targetContractId as Value::Array containing 32 byte-valued integers. ByteArrayKeyword accepts that representation, reference validation resolves the identifier, and Index::extract_values preserves the array. This match nevertheless returns None, so fetch_charter_election_windows skips the target read and contested insertion falls back to the generic windows. A production-path reproduction successfully submitted an array-valued application for a target declaring joinWindow = 86400, but the stored end date was start + 2,700,000 ms rather than start + 86,400,000 ms. Thus a submitter can bypass the declared election window by changing only the identifier encoding. Handle every identifier representation accepted by validation, or reject noncanonical representations at the PV14 validation boundary. Replace the new unit-test assumption that integer arrays cannot identify a valid target with a production-path regression.

In `packages/rs-drive/src/drive/document/insert_contested/add_contested_document_for_contract_operations/v1/mod.rs`:
- [BLOCKING] packages/rs-drive/src/drive/document/insert_contested/add_contested_document_for_contract_operations/v1/mod.rs:232-237: Preserve the end-date move when applicants use equivalent identifier encodings
  The new missing-entry fallback also triggers when the target and its windows are unchanged but applicants use different accepted identifier representations. The contested index treats Value::Identifier(id) and Value::Bytes(id.to_vec()) as the same resource, whereas vote_poll.unique_id() hashes their distinct serialized Value variants. Consequently, the second applicant's hash cannot locate the first applicant's end-date entry, and this condition silently skips the extension while accepting the application. A production-path reproduction with Identifier for the first applicant and Bytes for the second left a target declaring a one-day join window plus a one-week vote window scheduled to end after one day, not eight. Although the hash mismatch predates this change, the new fallback turns it into successful admission without the promised vote window. Resolve the original poll key or consistently canonicalize accepted charter target representations in the PV14 flow, and add a mixed-representation second-applicant regression.
- [SUGGESTION] packages/rs-drive/src/drive/document/insert_contested/add_contested_document_for_contract_operations/v1/mod.rs:290-299: Pin the stateless target-read cost with a regression test
  This branch adds a separate stateless estimate of the target-contract read. The new Drive tests call fetch_charter_election_windows directly, and the ABCI tests assert execution outcomes and balances rather than the accumulated estimation operations. Neither pins this read's estimated size, so removing the operation or changing its size could escape those assertions. Add a focused contested-insertion estimation test that checks the target-read cost at estimated_contract_max_serialized_size. Include an absent target to prove estimation remains state-independent and a non-charter contest to prove ordinary contests receive no additional target-read charge.

…tion-parameters

…from PV14 Validation accepts an identifier property as an identifier, as 32 bytes or as an array of byte values, and the contested index keys store them alike, but a contest's poll is hashed from its raw index values. Two applicants writing the same target two ways named one contest with two polls (two prefunded balances, an end date the second could not find), and an array-valued target was not recognized, so the election fell back to the generic windows. Index::extract_contested_values writes identifier-typed index values as Value::Identifier, gated by the new canonical_contested_index_values slot (None before 14, Some(0) in CONTRACT_VERSIONS_V6). The create action transformer and contested_vote_poll_for_document_properties use it; before 14 they take the values as given, as before. charter_election_target reads every accepted identifier form. Tests: production-path regressions for an array-valued application and for mixed-form applicants (both fail with the slot off), a dpp test of the canonicalizer at 13 and 14, and a focused estimate of the target read (present, absent and non-charter).
