feat(platform)!: multiple choice proposals take their description from a moderated text (PV15) - #5851
What this does: A multiple choice proposal used to carry its own description text. Now it carries none. Instead it points at a text stored somewhere else: a document in another contract, of a kind that moderators can remove, in a contract whose moderators are elected by the masternodes.
Value: A proposal can never be deleted, so text stored in it could never be taken down, and creating one costs almost nothing. With this, a description that turns out to be spam or abuse can be removed by moderators while the question and its vote stay in place.
Risks: Medium. It changes the schema of a system contract that has not shipped yet (protocol version 15), so nothing stored is affected. It makes multiple choice proposals depend on a contract outside the system contracts: no system contract hosts moderated text today. The text can still change after the proposal's two-hour edit window if the type hosting it allows edits. title and url are still free text. The JS spec was updated but not run locally; no full suite or mobile build was run.
Issue being fixed or feature implemented
#5848 adds multipleChoiceProposal with a required free-text description of up to 4096 bytes. The proposal is undeletable and costs only its storage, and nothing obliges anyone to enter a choice for it, so the description is a cheap place to put text that then stays for good.
#5849 and #5850 add a reference whose target the document names, with requirements on the named document type. This PR uses it for the description.
How this is stacked.#5848, #5849 and #5850 are merged, so the base is v5.1-dev and the diff is this change alone. The commits to review are d2e04ba810 (the change), 065f9a2875 (review fixes), e2bea23c63 (the condition on the type, below) and bd0e91c28b (a settled rule that counts every member); the rest are merges. The protocol version 15 note of this change is 33, a reference whose target the document names; #5848's contest among documents is 37.
What was done?
The contract
multipleChoiceProposal loses description and gains three required properties:
In words: the document type is a moderated one, it holds a string or a byte array that a moderator's removal takes away and that the document's author writes, and its contract declares moderators the masternodes elect. The three properties sit under the same two-hour immutable condition as title and url, so the owner can point the proposal at another description for two hours. Property positions are renumbered (url 4, open 5); the contract is unreleased.
The yes/no proposal type and choice are unchanged.
Before and after
Creating a multiple choice proposal:
Before: { title, description: "<up to 4096 bytes of text>", url?, open } accepted, text stays for good
After: { title, descriptionId, descriptionContractId, descriptionDocumentType, url?, open }
the text is a moderated document of an elected contract: accepted
the contract does not exist or has no such type: 40121
the type is private, or indexOnly: 40150, 40146
the contract elects no team, or its team may not delete from the type,
or the type has a deletion window and no rule for later,
or a rule that counts added members only for later documents: 40153
the type's removal record keeps its only text (deleteKeepsFields): 40153
the type's documents can be deleted by their owner, or never leave: 40143
no document with that id: 40120
the contract's declaration protects its owner from the elected team: 40135
After a moderator removes the description document:
Before: not possible, the text is part of the undeletable proposal
After: the proposal and its vote stay; the reference resolves to the removal record
Where it lives
packages/decision-proposals-contract: the schema; multiple_choice_proposal::properties::{DESCRIPTION_ID, DESCRIPTION_CONTRACT_ID, DESCRIPTION_DOCUMENT_TYPE} in place of DESCRIPTION; the Rust and JS contract tests; the README.
rs-drive-abci: the multiple choice tests register two description hosts (one with elected moderation, one moderated by its owner) and write a text before each proposal. A new test covers the accepted case and each refusal; the two-hour edit test now repoints the description. The ten genesis root pins in nullifier_batch_guard move with the schema.
docs/protocol/decision-proposals.md: a section on the description, what is checked and what it does and does not give. The book chapter on these references and note 33 of protocol version 15 name this use.
The description's type must be removable by the elected team, always. A review showed two hosts that passed every check with a description nobody could remove: a contract that leaves the type out of its elected team's deleteDocuments, and a type moderators delete only within a deleteWithin window with no settled deletion. Nothing a reference could declare stated either, so this PR adds the vocabulary: documentTypeRequirements takes a when of its own, judged once for the named type and reading no $property; a when may look into $electedAbilities (what the type's contract gives its elected team on the type) and test present / absent on moderatorAbilities.deleteWithin and deleteSettled. A later review round showed a third: a settled rule with approversPredateDocument (the default once a rule asks for more than one approval) counts a member the leader added only for documents created after its addition, so a description older than the members the rule takes is never deleted once settled. present / absent now also test $moderatorAbilities.deleteSettled.approversPredateDocument, and a windowed type qualifies only with a rule that does not set it (one approval, or approversPredateDocument: false). The operand names are mine and easy to change. What is left is the interim: a settled document is deleted by a seated team alone, and a rule taking several approvals takes that many members.
Elected moderation is required of the contract. Without it the author of a proposal could host the text in a contract they moderate themselves. "moderation": "elected" says the contract declares a team the masternodes elect. It does not say one is seated: until then the contract's interim moderators apply, which may be its owner or nobody. Requiring a seated team would need a new contractRequirements value.
The text's edit rules are its own type's. If the hosting type allows replaces, the author can change the description after the two hours and after choices were entered. The proposal's history keeps which document it pointed at, not what that document said. Nothing in the vocabulary can require the hosting type to be immutable.
A dependency outside the system contracts. No system contract has a moderated type, so a multiple choice proposal needs some other contract that is moderated, elected and has a qualifying type.
Which property is the description is left to the binding rule in the book (the first property in position order that fills body, then bodyBytes), not named by the proposal.
title, url and a choice's description remain free text. A choice pays the contest fund; a proposal's title does not.
How Has This Been Tested?
Targeted runs only, on macOS:
RUST_MIN_STACK=16777216 cargo test -p drive-abci --lib -- multiple_choice_proposal decision_proposal dynamic_document_reference create_genesis_state data_contract_create: 238 passed. The 12 multiple choice tests run against a hosted description; new: should_take_the_description_from_a_moderated_text_of_an_elected_contract.
cargo test -p drive-abci --lib -- nullifier_batch_guard::should_preserve_single_entry: 2 passed with the re-pinned roots.
cargo test -p dpp --lib --features all-system_contracts,fixtures-and-mocks,validation -- system_data_contract decision_proposal dynamic_reference slot_condition: 67 passed (the contract loads and registers at protocol version 15).
cargo test -p decision-proposals-contract -p platform-version: passed.
cargo clippy --all-targets --all-features --locked -- --no-deps -D warnings on drive-abci, decision-proposals-contract and platform-version: clean.
Not run: the JS contract spec (decisionProposalsContract.spec.js was updated and passes node --check, but mocha and eslint need the wasm build and installed dependencies), any full suite, the JS and wasm32 builds, the mobile builds.
In-place changes to shipped generations
The first commit edits no versioned method. The condition on the type extends apply_property_reference 1, check_document_type_schema 1 and document_reference_validation 1, all selected by protocol version 15 alone and unreleased; DocumentTypeRequirements gains a field, SlotCondition two variants at the tail and SlotConditionSetting one, on types no released version has stored. ModerationAbility (shipped) gains the associated constant ALL, which lists its variants and changes nothing it stores or decides. It changes the document schema of the decision proposals contract, which is registered from protocol version 15 (unreleased) and exists on no released network, test fixtures and pins, and documentation. The merge commits bring in v5.1-dev, #5848 among it, which is merged and lists its own in-place changes.
Breaking Changes
The decision proposals contract's multipleChoiceProposal schema changes at protocol version 15, before its first release: description is replaced by descriptionId, descriptionContractId and descriptionDocumentType. Protocol version 14 and earlier are unchanged.

Summary by CodeRabbit
New Features
Multiple-choice proposals now reference a description document in a moderated contract instead of storing description text directly. Proposal owners can update the description reference, title, and URL for two hours after creation.
Dynamic document references can now apply requirements to an entire target document type, including conditions based on elected moderation abilities and deletion settings.
Documentation
Updated guidance explains how description references and dynamic-reference conditions work, including the moderation and validation requirements for referenced documents.
…ntest among documents (PV15)
The decision proposals contract gains a multiple choice proposal: a
`multipleChoiceProposal` document is the question and each `choice`
document entered for it is an answer. The choices of one proposal contend
on a contested unique index keyed by the proposal's id, so masternodes
vote among them with the existing contest machinery. A proposal states
whether it is `open`: anyone enters choices for an open one, and only its
owner for one that is not (a propertyConstraints rule on `choice` reading
the proposal). The owner may edit the question's text for two hours after
creating it; `open` never changes.
So that an identity can enter as many choices as it wants, a contested
index may declare `"resolution": 2`
(`ContestedIndexResolution::MasternodeVoteOnDocuments`), admitted where
`parse_contested_documents_resolution` is set (protocol version 15). It
is resolution 0 (vote, abstain or lock) with each document a contender of
its own: the contest keeps a contender under its document id instead of
its owner's id, a vote towards a contender names the document id, the
stored result names the winning document, and the winner is stored under
the owner its document names.
The generations that write, check and award a contender branch on that
resolution in place. No contract registered before protocol version 15
can declare it, so every earlier version behaves as it did.

…s variants
The stored form mirrors `ContestedIndexResolution` variant for variant under
the same names. With the vote among documents it has three, all starting
`MasternodeVote`, which clippy's `enum_variant_names` refuses on a non-public
enum.
Co-Authored-By: Claude Fable 5.2 <noreply@anthropic.com>
Review of the contest among documents:
- The index parser took the decision to read `"resolution": 2` as a flag on
its admissions, set by its callers from `parse_contested_documents_resolution`
with `is_some()`. It is now a versioned method,
`ContestedIndexResolution::try_from_schema_value`, taking the platform
version: `None` converts the value as it always was, version 0 also reads 2,
and any other version is refused with `UnknownVersionMismatch`. The schema
parser and the registration cost both parse an index through
`Index::try_from_value_map_for_platform_version`, which calls it;
`Index::try_from_value_map` keeps the conversion that predates it. The
admissions struct is as it was.
- The comments of the decision proposals crate no longer say an identity
enters one choice.
- The contender, vote choice, winner and proof result docs say that the id
naming a contender is its document's id in a vote among documents.
- A test proves and verifies the vote state of a proposal whose choices
include two from one identity, while the vote runs and after it ends.

…(PV15)
A `permanentDocument` or `moderatedDocument` `refersTo` on an identifier
property may leave its target to the referring document: `contractIdProperty`
and `documentTypeProperty` name the properties holding the contract and the
document type, in place of `contractId` and `documentType`, and
`documentTypeRequirements` says what the named type must look like: named
slots, each a property it must have (`name`: `"$any"`, a property name, or a
name read from the referring document; `type`; `maxBytes`; `distinctFrom`),
and `require`, `anyOf` / `allOf` over slot names.
Version 1 of `apply_property_reference` (protocol version 15) parses the
declaration to `DocumentPropertyReferenceTarget::DynamicDocument`, appended,
and refuses its keys wherever else a reference sits. Nothing about the
target is known at registration, so `document_reference_validation` 1 checks
it when a document is written: the contract and the type exist, the type is
not private, meets the requirements
(`ReferencedDocumentTypeRequirementNotMetError`, 40153) and is of the
declared kind, and the document exists. A replace checks the reference
again when its value or a property it reads the target from changed.
Protocol version 14 and earlier keep `apply_property_reference` 0, which
does not read the keys.

…stration fee
The registration cost of a state transition is read from the schema, where an
index that does not parse is charged nothing. A vote among documents
(`resolution` 2) parses there through the versioned index parse; this holds the
fee to it, from the contract and from the serialization format, beside the two
resolutions that predate it.
Co-Authored-By: Claude Fable 5.2 <noreply@anthropic.com>
…-named references (PV15)
A refersTo naming its target through the referring document may list both
kinds, ["permanentDocument", "moderatedDocument"]: the named type is then
either, and the reference is checked as one of the kind the type is.
A documentTypeRequirements slot may carry `when`, a condition in the forms
of a propertyConstraints condition read against the referenced type:
$kind, $self, $moderatorAbilities.deleteKeepsFields,
$moderatorAbilities.changeFields and { "const": ... }. A property the
condition does not hold for does not fill the slot. So a contract can ask
that a text it points at is one a moderator's removal takes away, only
when the type is a moderated one.
The condition is stored in the compiled contract and carried by consensus
errors, so its decoders refuse a nesting past 16, and the parser holds one
`when` to max_document_type_requirement_condition_nodes (16).

…ecision-proposal-description-reference
Brings the multiple choice proposal types together with the references
whose target the document names. The two protocol version 15 notes
numbered 33 become 33 (a contest among documents) and 34 (a reference
whose target the document names).

…m a moderated text (PV15)
A multipleChoiceProposal no longer holds a description. It points at a
document saying what is being decided (descriptionId), of the contract and
the document type it names (descriptionContractId,
descriptionDocumentType):
- the document type is a moderated one holding a string or a byte array
that a moderator's removal takes away and that its author writes;
- the contract declares moderators the masternodes elect.
So a description can be taken down while the proposal, which is
undeletable, and its vote stay. The three properties may change for two
hours after the proposal is created, like its title and url.

Walkthrough
Multiple-choice proposals now reference descriptions stored in moderated documents instead of storing description text inline. Dynamic document-type requirements can evaluate elected moderation abilities and deletion settings through slot conditions and a new type-level when condition.
Changes: Moderated descriptions through dynamic references
Slot conditions can check elected moderation abilities and whether deleteWithin, deleteSettled, or settledApproversPredateDocument is declared. The parser validates the new condition forms.
documentTypeRequirements accepts an optional type-level when condition that cannot read $property. Evaluation uses the target type’s moderation metadata and elected abilities before checking slots. The WASM type and serialization include when.
The proposal schema replaces inline description with descriptionId, descriptionContractId, and descriptionDocumentType. Tests cover moderated reference validation and editing those fields during the two-hour window. Documentation and the stored contract fixture reflect the new schema.

Review of the references whose target the document names:
- A document naming an indexOnly document type is refused, paid, with
ReferencedDocumentTypeIndexOnlyError (40146) before anything is fetched.
Drive refuses to fetch such a document by its id, which failed the
transition with an internal error and no fee.
- The properties a dynamic reference reads its target from (the contract
id, the document type name, a slot's name property) can no longer be
listed under moderatorAbilities.changeFields: a moderator's change checks
no reference again.
- A rule reading through a dynamic reference is refused with a message
that says why.
- The schema shape of documentTypeRequirements is written by rs-dpp
(to_schema_value, which the parser reads back); wasm-dpp2 delegates.
- A replace changing a slot's name property is covered by a test.

The message refusing a refersTo that names its target through the

Final validation — Phase 1 + Phase 2
Static verification of a7f9bd3 confirms that the description requirements admit documents elected moderators cannot remove; the overlapping reports are consolidated into one blocking finding. Two documentation suggestions remain, while the separate removal-record test request is redundant with existing shared integration coverage. Current CI shows Kotlin build/tests and the book preview passing, no Rust test check, and the automated review pending; no local builds or tests were run.
Triage: critical by gpt-6.1-sol (effort low) — The large, cross-cutting diff changes consensus rules for contested-document voting and winner handling in packages/rs-drive-abci/src/execution/platform_events/voting/award_document_to_winner/v0/mod.rs, alongside consensus-enforced contract schemas and PV15 activation.
These findings are from an automated code review (PastaClaw). How to work through them:
- Verify each finding against the code; fix only what is real, as narrowly as the finding.
- If a finding is wrong, decline it on its thread in one or two sentences; the bot answers once and stops.
- To defer one, link a tracking issue on its thread (or reply asking the bot to file one).
- Suggestions don't block the merge, but most are worth fixing in this PR; judge each on its merits.
- Keep the PR's scope; don't grow it to satisfy hardening suggestions.
- Carried items were raised in an earlier round: read the thread first, and don't re-fix what you already fixed, declined or deferred there. Disputed and deferred items are already handled and are not listed.
In `packages/decision-proposals-contract/schema/v1/decision-proposals-contract-documents.json`:
- [BLOCKING] packages/decision-proposals-contract/schema/v1/decision-proposals-contract-documents.json:231-235: Require a description that elected moderators can actually remove
Combining `moderatedDocument` with the separate `moderation: "elected"` requirement does not establish an elected team's ability to remove the selected description. `DocumentTypeV2::document_reference_kind` checks deletion flags and record retention, while `ContractReferenceModeration::is_met_by` checks only that an elected declaration exists. Valid attacker-controlled hosts can therefore bypass the intended takedown boundary in three ways:
- Omit `DeleteDocuments` for the selected type from `moderated_document_types`, while retaining `moderatorAbilities.delete: true` on that type. Registration permits this unless the type also requests settled deletion. After seating, `Moderators::lacks` consults `ElectedModerators::allows`, and `deletion_authority` refuses deletion with 41201.
- Use an immutable, owner-undeletable type with `deleteWithin: 1`, required `$createdAt`, and no `deleteSettled`. The text still qualifies after its window expires, but ordinary deletion returns 41116 and settled deletion returns 41204.
- Declare `ownerProtected: true` and have the host's owner write the description. `fetch_deletable_document` consults `Moderators::protects` and refuses both ordinary and settled deletion with 41102, including after an election.
These are lasting exemptions after a team is seated, not just the disclosed interim limitation. Because proposal authors choose the host, they can publish descriptions that satisfy every new reference predicate yet remain unremovable. Require `ownerProtected: false` using the existing contract requirement, and extend the shared DPP reference requirements and generic ABCI validation to check the selected type's elected deletion grant and durable deletion capability. Add adversarial-host admission tests and actual deletion regressions for these cases.
In `docs/protocol/decision-proposals.md`:
- [SUGGESTION] docs/protocol/decision-proposals.md:218-220: Document how long a host can prevent its first moderation election
The interim limitation also depends on the host's `electionDelay`, which `moderation: "elected"` does not inspect. `ElectedModerators` accepts a delay of up to `u32::MAX` seconds, so an otherwise qualifying host can prevent the first election for roughly 136 years while its owner or nobody moderates. This is finite rather than literally permanent, but it materially changes the practical takedown guarantee. State this explicitly alongside the interim limitation. The existing `electionOpen` requirement can exclude hosts whose election delay has not elapsed if that stronger admission policy is intended; it still would not guarantee a seated team.
- [SUGGESTION] docs/protocol/decision-proposals.md:205-211: Include private and index-only target refusals in the description error table
The new table omits two refusals clients can receive when a proposal names an unsuitable description type: `ReferencedDocumentTypePrivateError` (40150) and `ReferencedDocumentTypeIndexOnlyError` (40146). The generic dynamic-reference validator checks these before the property requirements and reference kind, so an index-only target returns 40146 rather than the listed wrong-kind error. Add both cases. If the table is intended to describe validation precedence, also put document-type requirements before kind; otherwise clarify that its rows are not ordered by precedence.
Second review of the references whose target the document names:
- `require` is judged on every write that checks the reference, and only
the number of slots was bounded. It now names nothing twice: no term, no
slot within a group, no group with its slots in another order. With at
most four slots that is at most fifteen terms, where a contract could
repeat one slot thousands of times.
- The book's rule for which property fills which slot now starts by
choosing the set of slots, as consensus does, so a client reads every
reference Platform accepts.
- A test makes the assignment search take a property back and then
succeed.

…Id and documentType
A refersTo whose target the referring document names no longer has keys of
its own for it. It writes the keys every document reference has, read from
the document:
"contractId": "$self.descriptionContractId",
"documentType": "$self.descriptionDocumentType"
in place of contractIdProperty and documentTypeProperty. `$self` is the
document being written, as `$old` is the stored one in a rule. A slot's
name read from the document follows: "$self.bodyProperty" in place of
{ "property": "bodyProperty" }.
Both are read from the document or neither: one of them literal, or left
out, beside the other is refused, as is documentTypeRequirements beside a
target the schema names. Protocol version 14 gives the prefix no meaning
and refuses such a declaration. What is stored is unchanged.

Re-review — Final validation — Phase 1 + Phase 2
At head 3746732, the changes since the previous review tighten dynamic-reference requirement deduplication and clarify binding order; static inspection found no additional defect in that delta. The proposal schema and cited documentation sections are unchanged, so all three prior findings remain valid. Current CI reports no failed checks, including successful Kotlin build/tests, but lists no Rust-suite result; the review check remains pending, and no builds or tests were run locally.

…laude/dynamic-refers-to-when
Brings in the target read through `$self.` on contractId and documentType,
and a slot name read as "$self.<property>".
With `$self` now the referring document, the operand of a slot's `when`
that reads the property tried for the slot is renamed `$property`:
{ "not": { "contains": ["$moderatorAbilities.deleteKeepsFields", "$property"] } }
so each word means one thing in a declaration. `$self` in a `when` is
refused: a condition on the referenced type does not read the referring
document.

Brings in the target read through `$self.` and the `when` operand renamed
`$property`, and writes the multiple choice proposal's description with
them:
"contractId": "$self.descriptionContractId",
"documentType": "$self.descriptionDocumentType",
... { "not": { "contains": ["$moderatorAbilities.deleteKeepsFields", "$property"] } }
What the reference means is unchanged. The schema's bytes are not, so the
ten genesis root pins of nullifier_batch_guard move with it.
Co-Authored-By: Claude Fable 5.2 <noreply@anthropic.com>
A string property declaring both maxLength and maxBytes was held to its
maxBytes alone when a slot's maxBytes was checked, so one of at most two
characters (eight bytes) with a maxBytes of 100 failed a slot of eight
bytes it can never exceed. The bound is now the smaller of maxBytes and
four bytes a character of maxLength.

Brings in v5.1-dev at 97fb5f9: a refersTo is read as dynamic only where
protocol version 14 cannot read it (#5887).
The one conflict is protocol version 15 note 33, where both sides added a
sentence: it keeps this branch's use of the reference by the decision
proposals contract and the base's statement of which declarations version 1
reads as dynamic. The parser and its tests merge cleanly: the description
reference is a `moderatedDocument` whose `contractId` is written `$self.`,
which stays dynamic. No root pin, fee pin or stored contract fixture line
changes.

A tie goes to the earliest choice by creation time, then block height, then
core block height, and choices entered in the same block share all three:
among them the lower document id wins, not the one entered first. The
protocol guide and the README said only "the earliest choice", and the guide
that a vote nobody votes in keeps the first choice entered.

Full checklist in the description.
…every member (PV15)
A description's type had to let the elected team delete its documents and keep
a document deletable: no `deleteWithin` window, or a `deleteSettled` rule for
deleting past it. A rule could still leave a description for good. With
`approversPredateDocument` (the default once a rule asks for more than one
approval) a member the team's leader added counts only for documents created
after its addition, so under a rule taking more approvals than the leader and
the elected members give, a description older than the added members is never
deleted once settled.
- A `when` tests one more setting with `present` or `absent`:
`$moderatorAbilities.deleteSettled.approversPredateDocument`, the rule's
setting with its default applied, absent on a type with no rule.
`SlotConditionSetting` gains the variant at its tail; the parser, the native
schema check, the schema it is written back as and the JS types follow.
- The decision proposals contract's `multipleChoiceProposal` asks for it: a
windowed type qualifies with a settled rule that does not set it (one
approval, or `approversPredateDocument: false`). A host type whose rule
takes two approvals is refused with 40153 in the proposal tests.
- The abilities a `$electedAbilities` needle may name come from
`ModerationAbility::ALL`, held to the enum by a test, instead of a list
kept beside the parser.
The contract schema changes, so the ten nullifier_batch_guard roots, the
activation root and the stored contract fixture line of the decision proposals
contract are recomputed. Protocol version 15 is unreleased; protocol version
14 and earlier are unchanged.

Verification ran but could not confirm this finding. It is shown for review, not as a verified issue.
Reject hosts whose seated charter permits no deletion reason.
deleteDocuments only establishes a declared ability. The charter schema explicitly permits reasons: [] in packages/moderation-charters-contract/schema/v1/moderation-charters-contract-documents.json (Line 101). However, Moderators::unlisted_reason in packages/rs-drive-abci/src/execution/validation/state_transition/common/moderators.rs (Line 179) rejects every deletion from such a team. An otherwise qualifying host therefore accepts descriptions that its seated team cannot remove. (raw.githubusercontent.com)

…ing removed
The description's reference checks what its host declares, when the proposal
is written. It does not read the seated team, which changes afterwards: a
team does not moderate its own leader or active members, so a description one
of them wrote stays while the author holds the seat, and a team whose charter
lists no reason removes nothing. The protocol guide said "a description stays
deletable" without either.

In `docs/protocol/decision-proposals.md`:
- [SUGGESTION] docs/protocol/decision-proposals.md:228: Report the type-requirement error for unelected description hosts
An otherwise suitable owner-moderated host returns ReferencedDocumentTypeRequirementNotMetError (40153), not the 40135 listed here. The descriptionId reference is validated before descriptionContractId, and its new $electedAbilities condition fails before validation reaches the separate contract requirement. The should_take_the_description_from_a_moderated_text_of_an_elected_contract regression explicitly asserts this result for the unelected host. Remove the unelected-host case from this 40135 row, leaving owner protection here, or explain that 40135 describes the separate property's requirement rather than the error returned for this proposal. The 40153 row already covers contracts that elect no team.
…ed with
The protocol guide listed 40135 for a description hosted by a contract that
declares no elected moderation. The description is checked before the contract
it names, and its condition on the type fails first: no elected team is given
the deletion of the type, so the proposal is refused with 40153, as the
proposal tests assert. 40135 is what a contract whose declaration protects its
owner is refused with, after the description's checks.

At bc8f8a4, the updated refusal table matches validation precedence, including the earlier 40153 rejection of unelected description hosts. Static verification confirms all five prior findings are addressed, with no additional actionable findings; the overlapping base-branch change concerns separate PV15 voting behavior.

Basic explanation
What this does: A multiple choice proposal used to carry its own description text. Now it carries none. Instead it points at a text stored somewhere else: a document in another contract, of a kind that moderators can remove, in a contract whose moderators are elected by the masternodes.
Value: A proposal can never be deleted, so text stored in it could never be taken down, and creating one costs almost nothing. With this, a description that turns out to be spam or abuse can be removed by moderators while the question and its vote stay in place.
Risks: Medium. It changes the schema of a system contract that has not shipped yet (protocol version 15), so nothing stored is affected. It makes multiple choice proposals depend on a contract outside the system contracts: no system contract hosts moderated text today. The text can still change after the proposal's two-hour edit window if the type hosting it allows edits.
titleandurlare still free text. The JS spec was updated but not run locally; no full suite or mobile build was run.Issue being fixed or feature implemented
#5848 adds
multipleChoiceProposalwith a required free-textdescriptionof up to 4096 bytes. The proposal is undeletable and costs only its storage, and nothing obliges anyone to enter a choice for it, so the description is a cheap place to put text that then stays for good.#5849 and #5850 add a reference whose target the document names, with requirements on the named document type. This PR uses it for the description.
How this is stacked. #5848, #5849 and #5850 are merged, so the base is
v5.1-devand the diff is this change alone. The commits to review ared2e04ba810(the change),065f9a2875(review fixes),e2bea23c63(the condition on the type, below) andbd0e91c28b(a settled rule that counts every member); the rest are merges. The protocol version 15 note of this change is 33, a reference whose target the document names; #5848's contest among documents is 37.What was done?
The contract
multipleChoiceProposallosesdescriptionand gains three required properties:where
R, what is asked of the type as a whole, is{ "allOf": [ { "contains": ["$electedAbilities", { "const": "deleteDocuments" }] }, { "anyOf": [ { "absent": "$moderatorAbilities.deleteWithin" }, { "allOf": [ { "present": "$moderatorAbilities.deleteSettled" }, { "absent": "$moderatorAbilities.deleteSettled.approversPredateDocument" } ] } ] } ] }and
W, what is asked of the property holding the text, is{ "allOf": [ { "not": { "contains": ["$moderatorAbilities.deleteKeepsFields", "$property"] } }, { "not": { "contains": ["$moderatorAbilities.changeFields", "$property"] } } ] }In words: the document type is a moderated one, it holds a string or a byte array that a moderator's removal takes away and that the document's author writes, and its contract declares moderators the masternodes elect. The three properties sit under the same two-hour
immutablecondition astitleandurl, so the owner can point the proposal at another description for two hours. Property positions are renumbered (url4,open5); the contract is unreleased.The yes/no
proposaltype andchoiceare unchanged.Before and after
Creating a multiple choice proposal:
After a moderator removes the description document:
Where it lives
packages/decision-proposals-contract: the schema;multiple_choice_proposal::properties::{DESCRIPTION_ID, DESCRIPTION_CONTRACT_ID, DESCRIPTION_DOCUMENT_TYPE}in place ofDESCRIPTION; the Rust and JS contract tests; the README.rs-drive-abci: the multiple choice tests register two description hosts (one with elected moderation, one moderated by its owner) and write a text before each proposal. A new test covers the accepted case and each refusal; the two-hour edit test now repoints the description. The ten genesis root pins innullifier_batch_guardmove with the schema.docs/protocol/decision-proposals.md: a section on the description, what is checked and what it does and does not give. The book chapter on these references and note 33 of protocol version 15 name this use.Choices a reviewer may want to question
moderatedDocument, not the either-kind list feat(platform)!: either-kind targets and slot conditions for document-named references (PV15) #5850 adds: a permanent text could never be taken down, which is the point of the change.deleteDocuments, and a type moderators delete only within adeleteWithinwindow with no settled deletion. Nothing a reference could declare stated either, so this PR adds the vocabulary:documentTypeRequirementstakes awhenof its own, judged once for the named type and reading no$property; awhenmay look into$electedAbilities(what the type's contract gives its elected team on the type) and testpresent/absentonmoderatorAbilities.deleteWithinanddeleteSettled. A later review round showed a third: a settled rule withapproversPredateDocument(the default once a rule asks for more than one approval) counts a member the leader added only for documents created after its addition, so a description older than the members the rule takes is never deleted once settled.present/absentnow also test$moderatorAbilities.deleteSettled.approversPredateDocument, and a windowed type qualifies only with a rule that does not set it (one approval, orapproversPredateDocument: false). The operand names are mine and easy to change. What is left is the interim: a settled document is deleted by a seated team alone, and a rule taking several approvals takes that many members."moderation": "elected"says the contract declares a team the masternodes elect. It does not say one is seated: until then the contract's interim moderators apply, which may be its owner or nobody. Requiring a seated team would need a newcontractRequirementsvalue.positionorder that fillsbody, thenbodyBytes), not named by the proposal.title,urland a choice'sdescriptionremain free text.
