feat(platform)!: composite and flat indexOnly terminals with an entry payload - #4866
Merged

Conversation
An indexOnly index's `terminal` was restricted to `$ownerId` or an identifier property carrying a refersTo declaration. Nothing mechanical needed that: every path derives the member key through the same tree-key encoding the prefix levels use (the walkers and probes through `get_raw_for_document_type`, queries and executed proofs through `serialize_value_for_key`, synthesis through `decode_value_for_tree_keys`), and the only 32-byte assumption was the fee-estimation constant at the member level. The terminal may now be `$ownerId` or any schema property a prefix position admits, under the same shape limits (no arrays or objects; byte arrays of at most 255 bytes, strings of at most 63 characters), which now report through the same typed consensus errors. Other system properties stay refused: the rules that reason about `$createdAt` walk the prefix. Fee estimation sizes the member key by the terminal property's declared bound instead of a fixed 32, so the dry run keeps upper-bounding the applied fee for a 33-byte key, a string key or an integer key. Structural uniqueness spans the terminal value: one entry per (prefix values, terminal value). Protocol version 14 is unreleased, so the rule is relaxed in place.

… payload Two more extensions of indexOnly types on top of scalar terminals, both at the unreleased protocol version 14, which together make an indexOnly type a proved key-value table. Composite terminals: `terminal` may be an ordered list of properties and the member key is their encoded values concatenated. Every component but the last must be fixed width so equality on the leading components is one key range and synthesis can split the key back; the whole key is capped at 255 bytes. An index with no properties is flat: its entries live directly under a level of their own, keyed by a zero byte and the component names, which no property-name tree can collide with. The flat level is registration structure kept when the last entry goes; a flat index admits no aggregate, ranking, time-range, skip or preallocation keyword. Queries bind the components in order, with at most one range or `in` on the first unbound one, and a clause-free query on a type with a flat index scans the flat level. Entry payload: `entryPayload` names required, bounded, top-level scalars kept in no index; every entry's item carries them after the row commitment, length-framed in property-name order. The commitment still hashes them, so the delete probes and the executed-transition verifier compare the item's first 32 bytes and synthesis decodes the rest off the proved element. Fee estimation sizes the item by the commitment plus the payload bound and the member key by the components' widths, so every existing contract estimates as before. `Index::terminal` becomes `Option<Vec<String>>`; its JSON form accepts the bare-string spelling. The meta-schema admits the list form, drops `properties` from an index's required keys, and adds `entryPayload`. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>

Inline comments:
In `@packages/rs-dpp/src/data_contract/document_type/index/mod.rs`:
- Around line 1020-1029: The terminal ordering logic around prefix_order_by must
require trailing component fields to match the terminal’s declared component
order, not merely be components or an arbitrary permutation. Apply this
validation consistently in both terminal matchers, preserving non-terminal
ordering behavior and returning None for invalid suffixes such as reversed or
non-prefix component sequences.
In
`@packages/rs-drive/src/drive/document/delete/remove_indices_for_top_index_level_for_contract_operations/v2/mod.rs`:
- Around line 148-162: Update the v0 delete path in
remove_reference_for_index_level_for_contract_operations_v0 to use the
flat-aware stop height from the v1 behavior, based on key_info_path length minus
one when processing flat paths. Preserve the registered flat index level and
avoid pruning the empty zero bucket or its tree, while retaining the existing
stop height for non-flat paths.
In
`@packages/rs-drive/src/drive/document/insert/add_preallocated_index_tree_operations/mod.rs`:
- Around line 470-478: Update the preallocated index sizing around
index_only_item_estimated_value_size to derive member_key_max_size with
index_only_terminal_max_key_size when level_info.terminal is present, falling
back to DEFAULT_HASH_SIZE_U8 otherwise. Use member_key_max_size in the AllItems
entry so the dry-run matches the entry-insert key width.

Included review availability: Your plan provides up to 1 included review per hour; 0 remain after this review.
Validate composite-terminal ordering against the member key's component order and shared direction, including on proof verification. Reject flat level names that exceed GroveDB's key length limit, and apply projection coverage checks to clause-free flat scans before serializing responses. Preserve empty byte arrays in entry payloads and encode strings as raw UTF-8 so empty strings and NUL strings remain distinct in both stored payloads and row commitments. These rules are confined to unreleased PV14. Add schema boundary tests and end-to-end regressions covering sorting, proofs, serialized responses, payload round trips, and delete commitments. Update the index-only guide and payload keyword documentation.
Defer non-object document schemas to the core parser so contract creation returns InvalidContractStructure consistently in both validation modes. Estimate preallocated member keys from every declared terminal component, matching the entry insertion path. Cover malformed schema shapes and a 65-byte composite terminal with regression tests.
7 tasks
- Synthesis reads an empty byte-array key as an empty array, never as the tree-key null sentinel: every indexed property of an indexOnly type is required, so an empty key can only be an empty value. - The level info carries `flat`, stamped by the index that terminates there, and the delete walker reads it instead of inferring flatness from the path height. - The doctype layer estimate sizes its keys by the widest flat level key, keeping the 32-byte estimate for every property-name key. - The delete-side probe builds the member key through the write side's `index_only_member_key`; the payload encoder drops its unused platform version; the payload module is feature-gated once; the generic flat scan no longer computes a direction it can never use; the shared shape check imports its error types at the top. - Swift and Kotlin contract parsers accept the array spelling of a composite terminal (joined for display). - Tests: flat level key over the 255-byte cap and an empty terminal list are refused; a variable-width last component ranges against the key itself and round-trips an empty value; docstrings on the e2e helpers. - Book chapter reworded without em dashes.

⚠️ DEGRADED — Final validation — Phase 1 + Phase 2
⚠️ DEGRADED review. The primary review models were unavailable (gpt-6-astraunavailable: All credentials for model gpt-6-astra are cooling down (last error: usage_limit_reached: The usage limit has been reache), so this review ran on stand-in models:gpt-5.6-luna→muse-spark-1.3-contributor,gpt-5.6-sol→muse-spark-1.3-contributor,gpt-5.6-terra→muse-spark-1.3-contributor,gpt-6-astra→muse-spark-1.3-contributor. Both review phases and the independent verifiers still ran, but on weaker models, with Phase 1 capped athigheffort. Treat the verdict as provisional; a full-strength re-review will run on the next push once the primary models are back.
Composite/flat indexOnly terminals with entryPayload are coherently implemented across parsing, execution, queries, proofs and fees with no live consensus divergence; all retained items are suggestions. The most concrete is an empty-frame decode gap for fixed-width payload scalars, alongside a synthesis/parser width-function divergence, a matcher/route ordering mismatch, an unenforced flat-key disjointness assumption, missing codec tests, and a missing v14 changelog entry.

🟡 Suggestion: Missing v14 changelog item for the extended indexOnly grammar
packages/rs-platform-version/src/version/v14.rs:33-34
Composite/flat terminals and entryPayload are consensus-visible (new storable contract shapes, new GroveDB paths, new Item value layout) landing in unreleased protocol 14 with no table-slot bump, so the only release metadata is the v14.rs doc-comment changelog, which gains a numbered item per consensus change. The header still says 'v14 hosts six consensus changes' while listing 20+, and no item describes the indexOnly terminal/payload extension. Add a numbered item covering: terminal components beyond identifiers, flat levels, and entryPayload value layout with its update-immutability rule.

In `packages/rs-drive/src/drive/document/index_only_entry_payload.rs`:
- [SUGGESTION] packages/rs-drive/src/drive/document/index_only_entry_payload.rs:176-178: Empty frame for a fixed-width payload scalar decodes to Null instead of failing closed
encode_index_only_entry_payload_value never emits empty bytes for numeric, boolean, date, or identifier payload types (all encode to fixed widths; only byte arrays and strings can legitimately be empty). But the decode fallthrough arm calls decode_value_for_tree_keys directly, and that function returns Ok(Value::Null) for empty input before any type dispatch (property/mod.rs line 1537). So a corrupted entry carrying a zero-length frame for a fixed-width payload property decodes to Null for a required property instead of raising the corrupted-entry error the module docs promise ('fails closed on any framing mismatch, never a partial document'). The outcome is deterministic across nodes so it is not consensus-breaking, but a synthesized document would carry Null where the schema requires a scalar. Guard the fallthrough arm against empty input.
- [SUGGESTION] packages/rs-drive/src/drive/document/index_only_entry_payload.rs:142-188: Payload codec refusal paths and composite-tail In operator lack direct test coverage
The new fallible pure functions encode_index_only_entry_payload / decode_index_only_entry_payload have no unit tests (no #[cfg(test)] module in the file): truncated length frames, trailing bytes past the last property, invalid UTF-8 in a string payload, and the empty-frame-for-fixed-width case above are untested. E2E coverage round-trips honest payloads including empty and NUL values, but never feeds a malformed item through decode. Likewise the composite tail lowering implements In, BetweenExcludeLeft, BetweenExcludeRight, and LessThanOrEquals arms that no e2e test exercises (tests cover Equal, LessThan, GreaterThan, GreaterThanOrEquals, Between, BetweenExcludeBounds). Add focused unit tests for the codec refusal paths and at least one composite-tail In query test with proof parity.
In `packages/rs-drive/src/query/index_only_synthesis.rs`:
- [SUGGESTION] packages/rs-drive/src/query/index_only_synthesis.rs:1258-1271: Synthesis splits composite keys with max_size() while admission and fees use max_byte_size()
synthesize_index_only_document derives each leading terminal component's split width from property_type.max_size() (unversioned; char-count for strings), while apply_index_only admits fixed-width leading components via min/max_byte_size(platform_version) and fee estimation (index_only_terminal_max_key_size) sums max_byte_size. For every type that can lead today (integers, boolean, date, identifier, fixed byte array; strings are barred from non-last positions) the two coincide, so there is no live decode bug. The divergence is fragile in two ways: max_size and max_byte_size disagree for strings, and synthesis takes no PlatformVersion so it cannot even express the version-dependent (>8 checked_mul vs wrapping) byte width. A future fixed-width type where the two disagree would silently mis-split member keys between prover and verifier. Thread PlatformVersion through synthesis and use max_byte_size, or centralize one versioned width helper shared by the walkers, estimation, and synthesis.
In `packages/rs-dpp/src/data_contract/document_type/index/mod.rs`:
- [SUGGESTION] packages/rs-dpp/src/data_contract/document_type/index/mod.rs:1020-1029: Terminal matcher is order-permissive while terminal route is order-strict
matches_including_terminal (and the contiguous variant at lines 1185-1194) accept any trailing permutation of terminal components as terminal_used, but index_only_terminal_clause_selection then enforces contiguous-from-first equality binding and declared-order orderBy, returning a shape error otherwise. Selection picks a single best index with no fallback, so when the matcher picks an index whose terminal binding the route rejects, the query fails even if a second index could have served it. Selection and routing agree to fail deterministically (no consensus divergence), but serveable queries can be rejected. Consider making the matcher order/contiguity-aware or falling back to the next candidate on shape mismatch.
- [SUGGESTION] packages/rs-dpp/src/data_contract/document_type/index/mod.rs:468-482: Flat-level zero-byte disjointness is assumed, not enforced
flat_level_key_for/is_flat_level_key rely on 'property names never contain a zero byte' to keep a flat level ("\0name...") disjoint from property-name and grid-qualified trees. No parser check rejects '\0' in a property, index, or document-type name, so the invariant holds by convention (JSON names in practice) rather than by validation. A hostile or accidental '\0'-bearing name would alias or evade the flat-level detection in contract setup, walkers, probes, and query routing. Reject '\0' at schema parse time, or downgrade the comment to an explicit unchecked assumption.
In `packages/rs-platform-version/src/version/v14.rs`:
- [SUGGESTION] packages/rs-platform-version/src/version/v14.rs:33-34: Missing v14 changelog item for the extended indexOnly grammar
Composite/flat terminals and entryPayload are consensus-visible (new storable contract shapes, new GroveDB paths, new Item value layout) landing in unreleased protocol 14 with no table-slot bump, so the only release metadata is the v14.rs doc-comment changelog, which gains a numbered item per consensus change. The header still says 'v14 hosts six consensus changes' while listing 20+, and no item describes the indexOnly terminal/payload extension. Add a numbered item covering: terminal components beyond identifiers, flat levels, and entryPayload value layout with its update-immutability rule.
- One `fixed_tree_key_width` helper on the property type: the parser's leading-component rule and synthesis's member-key split both read it, so they can no longer disagree. - A payload frame that is empty for a fixed-width property is a corrupted entry, not a null value. - The terminal matchers admit a trailing run of components only in declared order, so a query no member-key walk can serve falls through to the next index instead of being claimed and then refused. - A terminal component name carrying a zero byte is refused at parse time: the flat level key reserves it as its separator. - Tests: payload codec refusal paths (truncated frame, trailing bytes, invalid UTF-8, empty fixed-width frame) and a round trip; `in` on the last and on a leading composite component with proof parity; the matcher's declared-order rule; the zero-byte refusal.

Three related extensions of indexOnly document types, all at protocol version 14 (unreleased, so the rules are extended in place), which together make an indexOnly type usable as a proved key-value table. The motivating case is the app-connect login response (#4842): a lookup from a request hash to the wallet's ephemeral key and ciphertext, keyed by the responding identity, with no primary row, no reference and no tree levels per request.
terminalwas restricted to$ownerIdor arefersToidentifier, andidentityPublicKeyreferences were refused. That was a design rule, not a mechanical one: every write, read, delete and proof path derives the member key through the same tree-key encoding the prefix levels use, and the only 32-byte assumption was a fee-estimation constant.terminalmay be an ordered list of properties; the member key is their encoded values concatenated. An index with nopropertiesat all is flat: its entries live directly under a level of their own, so a lookup by the leading components is one key range in one Merk.entryPayloadnames top-level properties stored in every entry's item after the row commitment instead of in a key: the type's value slot.What was done?

cargo test -p dpp --lib -- index_only_tests try_from_schema index::tests: 413 passed. New parser tests: string, byte-array, integer, identityPublicKey and nested-leaf terminals accepted; over-cap byte arrays and strings, object names and$createdAtrefused; composite terminal below a prefix; flat composite terminal (flat level present in the structure); variable-width leading component, over-cap composite key, duplicate component, aggregates on a flat index and a flat index on a stored type refused; entry payload accepted on the login shape, and refused when also indexed, unbounded, optional, unknown or on a stored type.cargo test -p drive --lib: 3828 passed (the whole library suite). The scalar-terminal fixture gainsloginKeyResponse(flat composite terminal plus entry payload) andreaction([postId] → kind ‖ $ownerId). New e2e tests: the flat entry's layout and payload framing, no property-name trees for a flat index, uniqueness across the key, lookup by request hash with the payload synthesized and proof parity, point lookup existence and absence proofs, clause-free flat scan with proof, keyset pagination over the second component with proofs, delete-by-values with a mismatched payload refused, estimated fees upper-bounding applied fees on insert and delete, the flat level surviving a drained bucket, and the prefixed composite ranging over its leading component.cargo test -p drive-abci --lib -- batch::tests::document: 238 passed, including the newtest_executed_flat_composite_create_and_delete_proofs(full pipeline: the create's entry under the flat level keyed byhash ‖ owner, the executed-create proof located from the transition's values and checked against the recomputed commitment, the executed delete proved absent).cargo clippy -p dpp -p drive --all-targets -- -D warningsandcargo clippy -p drive-abci --tests -- -D warnings: clean.cargo fmt --all -- --check: clean.cargo check -p dppwith and without thevalidationfeature: clean.Breaking Changes
Consensus at protocol 14 (unreleased): contracts may now declare non-identifier, composite and flat terminals and an
entryPayload; contracts naming anidentityPublicKeyreference as a terminal are now accepted. Everything previously accepted parses identically and estimates identically.Index::terminalchanges type fromOption<String>toOption<Vec<String>>for Rust consumers; its JSON form accepts both spellings and emits the array.Checklist
