Summary

• Problem: cgr index keeps a node property only when the label's protobuf message declares a field of that name. codec/schema.proto had fallen behind what the graph holds:
  • Interface, Enum, Type, Union kept no start_line/end_line, docstring, decorators, modifiers or is_exported; Type and Union not even a path. A reader of index.bin could not locate or describe them.
  • Function / Method / Class lost path, modifiers, start_col and anchor_hash. Function and Method also lost name_start_line/name_start_col and positional_params. Function lost is_body_scoped_name and is_macro; Method lost is_exported, is_property and overrides_external.
  • Module lost its line span and the unresolved_specifiers/unresolved_references waiting lists. ModuleInterface/Implementation lost module_type.
  • As a result, diff-index could not see a type that moved, changed its docstring or stopped being exported. In the repro only Circle showed up.
• Fix:
  • schema.proto gains those fields, numbered from 20 in each message so they stay clear of fields other open changes add lower down: Class.field_types/generic_arity = 9, Method.signature = 12, Function.object_binding = 14, Interface.generic_arity = 6, Resource.project = 4. Bindings regenerated (gencode 6.31.1, as checked in).
  • The writer needs no change: it already copies every property whose name the message declares.
  • The parity test's _NOT_EXPORTED list, which recorded the gaps as "the current state, not an endorsement" (Node properties in NODE_SCHEMAS can be absent from schema.proto with nothing checking #1490), shrinks to what is checkout- or call-specific: absolute_path, Project.root_path, and the Gloss write nonce and derived lists. It stays default-deny, so a new property must be exported or argued onto that list.
• Not here: Resource.project, which the issue also lists, is added by fix(schema): Resource declares the project its ENDPOINT kind carries #3120 (and [Bug]: cgr doctor still fails on graphs cgr built (after #2431): TS extends/implements of a type alias, and finding nodes orphaned by a capture-set change #2536).

Demo

The GIF plays the session step by step. The issue's shapes.ts is indexed with cgr index, the interface/enum/type payloads in index.bin are printed, then the issue's edit is applied and diff-index is run on the two indexes. The edit un-exports Shape and Point, changes their docstrings and shifts every line.

• main: Colour and Shape hold qualified_name, name, path, and Point only qualified_name and name. diff-index lists only Circle, Circle.area and Circle.constructor.
• This branch: each payload carries its docstring, start_line/end_line, is_exported, modifiers and start_col (Point its path too). diff-index lists Colour, Point and Shape as well.

Type of Change

• Bug fix (non-breaking change which fixes an issue)
• New feature (non-breaking change which adds functionality)
• Breaking change (fix or feature that would cause existing functionality to not work as expected)
• Documentation update
• Refactoring (no functional changes)
• Performance improvement

Related Issues

Fixes #3206

Test Plan

• All existing unit tests pass (make test): related suites run, full suite see below
• New tests added for new functionality
• Integration tests pass (if applicable)
• Manual testing performed

Red/green TDD in codebase_rag/tests/test_index_exports_graph_properties.py, through the real cgr index command (CliRunner), diff_indexes, and a polyglot index run.

• Red on main (87a8f58): 5 failed, 1 passed.
  • test_a_type_keeps_its_span_docstring_and_export[interface, enum, type-alias]: Shape 2–4, Colour 6–9 and Point 11, each with its docstring, is_exported and path.
  • test_diff_index_sees_a_type_that_moved_or_stopped_being_exported: after the issue's edit, Shape and Point change is_exported True → False, and Colour moves 6 → 8.
  • test_methods_and_functions_keep_their_signature_facts:
    • Python W.run keeps overrides_external and path, and W.p keeps is_property;
    • helper keeps positional_params ["a", "b"];
    • a C static function keeps modifiers;
    • a Rust macro_rules! keeps is_macro.
• Green on this branch: 6 passed.
• Guard (passes on main and here): test_every_property_a_run_writes_is_exported_or_listed. Every property an index of Python, Java, Rust, Go, C#, C and TS writes is a proto field or on the closed list.
  • A writer that starts emitting a new property already fails the conftest's NODE_SCHEMAS audit (checked by mutation: a stray bogus_prop fails it).
  • The parity test then demands a proto field for a declared one, so the chain is closed.
• Updated: test_protobuf_node_property_parity.py, with _NOT_EXPORTED reduced as above. Its test_the_unexported_list_names_only_real_absences fails until the now-exported entries are removed.
• Wider runs:
  • Every protobuf / index / diff / codec / provenance / manifest / export / snapshot / schema test file (39 files): 458 passed, 1 skipped.
  • Full suite (-n 3): 17,712 passed, 177 skipped. The 109 failures all appear in this environment's baseline on main: LLM/token-counter, dependency-patch and MCP-query tests with no network or keys.
  • Full suite with Memgraph: queued in the local serial runner; the result is added to this description when it lands. CI runs it too.
• Manual: the demo above.

📝 Walkthrough

The protobuf schema adds graph properties to node payloads. The protobuf ingestor can update existing node properties. Tests cover property parity, serialized index contents, index diffs, and unresolved references.

Changes: Index Property Export

Layer / File(s)	Summary
Protobuf property fields codec/schema.proto, codec/schema_pb2.py, codec/schema_pb2.pyi	Protobuf messages and generated declarations add path, source-location, documentation, modifier, export, and other graph-property fields to module and symbol payloads.
Unresolved-reference updates codebase_rag/services/__init__.py, codebase_rag/services/protobuf_service.py, codebase_rag/graph_updater.py	A runtime-checkable protocol and protobuf ingestor method support property updates on existing nodes. For non-queryable ingestors that support the protocol, the graph updater writes cleared or pending Module unresolved references.
Property parity and index tests codebase_rag/tests/test_protobuf_node_property_parity.py, codebase_rag/tests/test_index_exports_graph_properties.py	The exclusion list removes many prior exclusions for graph-carried properties. Tests check that emitted properties have a protobuf field or explicit exclusion, and verify selected index properties, diff changes, and unresolved-reference metadata.

Merge Risk: ⚪ Minimal · up to 7115a

This change makes the index file keep more graph properties, such as spans, docstrings and export status, so diff-index can detect changes to those symbols. No concrete merge-blocking risk was found in the supplied changes.

Full details: Description check

Explanation

The description follows the required template and includes the summary, demo, change type, issue, test plan, and checklist. It also documents test results, baseline failures, deferred work, and manual validation. The pre-commit checklist is not fully checked, and Memgraph results are still pending, but these are non-critical omissions.

Full details: Linked Issues check

Explanation

Direct issue #3206 has coding requirements, and the reviewed head satisfies them. codec/schema.proto and the regenerated bindings retain the listed metadata for the affected node labels, including module waiting lists. Resource.project is present in the current schema; the PR correctly defers its separate implementation work. The index, diff, polyglot, unresolved-reference, and default-deny parity tests cover the required behavior and exclusions.

Full details: Out of Scope Changes check

Explanation

The changes stay within #3206. NodeUpdateProtocol, the protobuf node update path, and the graph-updater fallback preserve Module.unresolved_references when the protobuf sink cannot run graph queries. The schema bindings and tests support the required index behavior. No unrelated production change is demonstrated.

[Critical impact] No blocking issues were found; the focused CLI and binary compatibility checks support merging these changes.

T-Rex evidence

Command output from the check

• Exact baseline command and observed output: seven failures, five passes, absent type fields, and no matching type-property deltas.

Command output from the check

• Exact head command and observed output: twelve passes and visible location, documentation, and export changes through the diff-index CLI.

Command output from the check

• Initial execution failed with exit 127 because the prepared interpreter target was missing.

Command output from the check

• Documented frozen uv sync completed successfully and restored the environment.

Summary

This PR extends codec/schema.proto so cgr index keeps graph properties it previously dropped.

• Adds locations, documentation, export flags, parameter facts, hashes, and module waiting lists.
• Updates both generated Python bindings without changing existing field numbers.
• Adds export and diff-index regression tests and removes the corresponding parity-test exclusions.
• All 12 focused export and property-parity tests passed. The CLI preserved type properties and reported changes to locations, documentation, and export status.
• Binary compatibility checks passed for all 63 added fields across 10 messages. All 191 existing field identities remained unchanged, and the tested data survived cross-version serialization. The adjacent protobuf tests also passed all 26 tests.

No actionable issues were found in the checked changes. These changes are safe to merge.

🗄️ Data Integrity & Integration | 🟠 Major | ⚡ Quick win

Preserve positional_params presence in the index format.

positional_params = [] means that a function or method declares no positional parameters. An absent value means that the parameter kinds are unknown. The writer stores both states in the repeated protobuf field, but protobuf does not preserve presence for an empty repeated field. _payload_fields then omits the empty list, so _node_delta receives identical payloads for both states. diff-index therefore misses this reachable signature change when the node identity remains stable.

Add a presence marker to both Function and Method, set it when the graph supplies positional_params including an empty list, and include it in the diff payload.

Suggested fix

 message Function {
   ...
   repeated string positional_params = 26;
+  optional bool positional_params_present = 27;
 }

 message Method {
   ...
   repeated string positional_params = 26;
+  optional bool positional_params_present = 27;
 }
