…eDocument) `refersTo: permanentDocument` only accepts a document type with `canBeDeleted: false`, so a reply to a deletable comment, or a like on a deletable post, cannot declare what it points at. `deletableDocument` is its disjoint counterpart: same declaration (`contractId`, `documentType`, `propertyAgreement`), but the referenced type must ALLOW deletion (`ReferencedDocumentTypeNotDeletableError`, 40131, otherwise), so a declaration always states which guarantee the reference carries. `permanentDocument` is unchanged. Write time: the referenced document must exist and every agreement pair must hold, exactly as for `permanentDocument`. Afterwards the target may be deleted; nothing blocks that. What a WRITER may not do is leave the reference dead: every replace of the referring document re-validates a `deletableDocument` reference, touched or not, so a dead one has to be repointed at a document that exists or cleared. A writer gate is therefore only ever checked against the new target. An `immutable` reference can only be cleared, and only once its target is gone: the replace action records the identifier each removed property held, and the immutable check lets that one change through after reading state. The referring document can always be deleted. Reads: chained queries and composite by-id joins accept either kind as the join source. A `permanentDocument` source keeps the strict rule (a missing document is an invalid proof). A `deletableDocument` source leaves a deleted document out and REPORTS its id: `missing_outer_ids` on the chained result, one list per sub-query on the composite result, on the unproven wire (two new proto fields, regenerated clients), in the proof verifier's types, and as `missingOuterIds` / `missingIds` in the wasm SDK. The omission is proven: every derived id is a queried key, and grovedb refuses a proof without the coverage to show one present or absent (#4852), which the new adversarial tests pin on the tolerant path, where no assembly rule stands behind it. Also: allowed as an indexOnly member key; refused for `preallocated` (the trees would outlive the target); a property cannot switch kind on a contract update. A dead reference stays dead: since #4859 a document id commits to the nonce of its create transition, so a deleted id can not be created again and a reference means that one document or nothing.

…delete-by-type-03196d #4859 makes a document id single use from protocol version 14, and #4860 adds `refersTo: deletableDocument`. Both change how moderator deletion works: - A removed document id can not be created again, so a removal record is written once and never replaced. The replacement path goes: the read of an existing record in the transform, `replaces_existing`, and the identity the refund forfeiture spared. Forfeiting the whole batch is exact again. - For references a document type moderators can delete from is deletable, by anyone: a `permanentDocument` reference refuses it and a `deletableDocument` reference accepts it, at contract registration and at document write, the two checks #4860 left to this work. `StateError` discriminant 130 (after #4860's 129), changelog item 19. The gRPC clients and grovedb-structure.json are regenerated. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>

refersTo: permanentDocumentonly accepts a referenced document type withcanBeDeleted: false. A reply to a deletable comment, a like on a deletable post, a bookmark of a deletable note cannot declare what they point at, so they get no existence check, nopropertyAgreement, no writer gate, no indexOnly member key and no provable join.This adds
refersTo: deletableDocument, the disjoint counterpart.permanentDocumentis unchanged, including its strict join rule.Builds on #4852, which pinned the proof soundness the join part relies on, and on #4859, which makes a document id single use: without it, the owner of a deleted target could create the same id again with different content and every existing reference would silently point at it.
What was done?
The target (dpp).
DeletableDocument { contract_id, document_type_name, property_agreement }is appended toDocumentPropertyReferenceTarget(@append_only, consensus-serialized inside errors). Same declaration shape aspermanentDocument; a sharedas_document_reference()accessor returns the declaration pluspermanent: bool, so call sites stop matching on the variant. Meta-schema v3 gains the enum value in place (PV14 is unreleased).Disjoint target types. A
permanentDocumentreference demands a type that forbids deletion (40122, as before); adeletableDocumentreference demands one that ALLOWS it, so the declaration always states which guarantee the reference carries. NewReferencedDocumentTypeNotDeletableError, state code 40131 (next free in the document band; 40128 to 40130 are taken), appended at the END ofStateErrorwith its discriminant (129) added to the frozen-discriminant test. Enforced at contract registration and at document write.Write time. The referenced document must exist and every
propertyAgreementpair must hold, exactly as forpermanentDocument.After the target is deleted. Nothing blocks the deletion and nothing cleans up after it. What a writer may not do is leave the reference dead:
deletableDocumentreference, touched or not. A dead one must be repointed at a document that exists, or cleared; leaving it, or pointing it at another missing document, fails withReferencedEntityNotFoundError(40120). This costs one document fetch per replace of such a document.{ "$ownerId": "$ownerId" }) is therefore never evaluated against a missing document: it is checked against the NEW target, or not at all once the reference is cleared.immutablereference cannot be repointed, so clearing is its only repair, and only once the target is really gone. The replace action now recordsremoved_identifier_fields(the identifier each removed top-level property held), andvalidate_state_v1's immutable check lets a removeddeletableDocumentreference through afterdeletable_document_reference_target_is_goneconfirms it from state. While the target exists, clearing still fails with 40128. Nested references get no carve-out (immutablelists top-level properties only).required+immutableleaves the document replaceable by nobody; it can still be deleted.Reads (rs-drive). Chained queries and composite by-id joins accept either kind as the join source.
permanentDocumentsource: unchanged. A missing document is corrupted state on the server and an invalid proof in the verifier.deletableDocumentsource: a deleted document is left out of the documents and its id is REPORTED:ChainedDocumentsResult::missing_outer_ids,CompositeDocumentsResult::sub_result_missing_ids(one list per sub-query, empty unless it is a by-id join), in first-appearance order.Wire and SDKs.
ChainedDocuments.missing_outer_ids = 3andCompositeDocuments.SubQueryResult.missing_ids = 3(unproven mode; the proven mode carries a proof and the verifier computes the same lists). Both dispatchers fill them; gRPC clients regenerated; proof-verifier result types carry them; rs-sdk mock codecs extended; wasm-sdk exposesmissingOuterIdsandmissingIds; wasm-dpp2 mirrors the new target and error code.Also. Allowed as an indexOnly
terminal(member key): it is an Item, not a Reference, so entries outlive a deleted target. Refused forpreallocated: the trees would outlive the target with other owners' entries inside (no new code, the binding matcher only acceptspermanentDocument). A property cannot switch between the two kinds on a contract update (the schema differ already refused it; test added for both directions). A dead reference stays dead: since #4859 a document id commits to the nonce of its create transition, so a deleted id can not be created again and a reference means that one document or nothing.Docs: book index-only chapter, js-evo-sdk README, meta-schema descriptions, join docs in rs-drive, rs-drive-proof-verifier, dash-platform-queries and wasm-sdk.
Notes for the reviewer:

On top of current
v4.2-dev(b924b25, includes #4859). Rebased twice: over #4856 (its only conflict was a generated Python client, resolved by regenerating every client from the merged proto), then over #4859 (clean; the new lifecycle tests neededset_id_for_creation, like the other test sites #4859 adjusted, because they reference the id of their local copy).contractId/propertyAgreement, member key accepted,preallocatedrefused, update cannot change kind, shared accessor,Display, frozen discriminants, meta validators. 36 targeted tests pass; a wider run (try_from_schema validate_update property::tests state_error meta_validators) passed 714 before the rebases.deletable_document_reference.rs(throughprocess_raw_state_transitions): write-time rules; 40131 at write time; repoint-or-clear after a real deletion, including "untouched replace fails" and "repointing at another missing document fails"; writer gate checked against the repointed target's owner; immutable reference clearable only once its target is deleted, never repointable, and not re-settable afterwards; a document with a dead reference can be deleted.

Breaking Changes
Consensus, within unreleased protocol version 14: a new
refersTotarget in meta-schema v3, a new state error (40131), and re-validation ofdeletableDocumentreferences on every replace. No effect on contracts that do not use the new target. The unprovengetDocumentsV1 response gains two repeated fields (additive).Checklist:
