Summary

• ty 0.0.13 → 0.0.84. The new ty reports about 100 errors plus 11 warnings, and it now exits 1 on warnings too. It also matches # type: ignore[code] against its own rule names, so every mypy-coded ignore stopped suppressing anything. All of them are fixed at the root, with no new ignores, cast, Any or object. Both CI typecheck environments (with and without the neo4j extra) and the repo-wide pre-commit hook are clean, warnings included. The fixes include PropertyParams (a read-only Mapping) for query params, TypeIs/TypeGuard narrowing, a QueryingIngestorProtocol, a typed CypherAgent seam, ResultValue for fetched rows, and turning the TYPE_CHECKING-only deps protocols into plain classes.
• A real bug ty surfaced, in its own commit: in JavaTypeInferenceEngine, an @abstractmethod stub in JavaVariableAnalyzerMixin sat ahead of JavaMethodResolverMixin in the MRO. At runtime _resolve_java_method_return_type was the stub, which returns None, so the name-based return-type fallback (getter heuristics and friends) never ran.
• pymgclient 1.6 (supersedes build(deps): bump pymgclient from 1.5.2 to 1.6.0 #2332) and tiktoken 0.14 (supersedes build(deps): bump tiktoken from 0.12.0 to 0.14.0 #2331).
• TypeScript oracle → 6.0.3, not 7 (supersedes build(deps): bump typescript from 5.9.3 to 7.0.2 in /evals/oracles/ts_oracle #2323). TS 7 is the native port: its package exports only version plus typescript/unstable/*, so ts.ScriptTarget is undefined and all 21 oracle tests fail. 6.0.3 is the last release with the compiler API, and its output is byte-identical to 5.9.3 on 251 rxjs source files. Dependabot now ignores typescript >=7.
• syn 3 for the Rust oracle (supersedes build(deps): bump syn from 2.0.118 to 3.0.6 in /evals/oracles/rs_oracle #2328). syn 3 moved the negative-impl ! out of ItemImpl::trait_ into modifiers.polarity, a one-line change for the oracle, which ignored it anyway. Oracle output is byte-identical to the syn-2 build on syn's own sources (1.7 MB of output), on proc-macro2, and on a negative-impl case.
• C# frontend: MSBuild.Locator 1.11.2 and Roslyn 5.6.0 (supersedes build(deps): bump Microsoft.Build.Locator from 1.7.8 to 1.11.2 #2333 and Bump Microsoft.CodeAnalysis.CSharp.Workspaces from 5.0.0 to 5.9.0 #2334).
  • Locator ≥1.8 fails the build with MSBL001 because the transitive Microsoft.Build.Framework would ship its runtime assembly. Fixed with an explicit ExcludeAssets="runtime" reference.
  • Bump Microsoft.CodeAnalysis.CSharp.Workspaces from 5.0.0 to 5.9.0 #2334 bumped only CSharp.Workspaces, but each Roslyn package pins Workspaces.Common exactly, so the pair must move together.
  • Roslyn 5.9's Workspaces.MSBuild ships net10.0 only, while the frontend deliberately targets net8.0, so this stops at 5.6.0, the last line with net8.0. Dependabot now groups Microsoft.CodeAnalysis.* and ignores Roslyn >=5.9 and Microsoft.Build.Framework >=18.

#2330 (ty) is superseded too. #2240 (pip tree-sitter 0.26) was already superseded on main.

Demo

No user-visible change: dependency bumps plus type-level fixes. The few behaviour changes are defensive or internal, and each is pinned by a test:

• the Java return-type fallback
• cgr stats on a null label list
• the MCP client on a non-text reply
• semantic-search rows with malformed lines or labels

Type of Change

• Bug fix
• New feature
• Performance improvement
• Refactoring (no functional changes)
• Documentation
• CI/CD or tooling
• Dependencies

Test Plan

• Unit tests pass (uv run pytest -n auto -m "not integration"): 14180 passed. The two failures are TestCsharpGuard cases that need a prebuilt C# oracle DLL, which the sandbox's .NET 8 SDK cannot build (the oracle needs SDK ≥10). CI has it.
• New tests added, red before the fix and green after, with negative cases:
  • FunctionLocations.update
  • the Java fallback
  • stats null labels
  • MCP non-text content
  • semantic-search narrowing
  • unixcoder decode
  • Milvus kwargs
  • the ast-grep selector-less rule
  • split-import indentation
  • write-only-ingestor reads
  • Dependabot holds and groups
• Integration tests pass (make test-integration, requires Docker)
• Manual testing:
  • all C# tests (381) run against a real .NET 8 SDK on Roslyn 5.6 + Locator 1.11.2
  • TS/JS oracle tests (23) on TypeScript 6.0.3
  • Rust oracle tests (9) on syn 3
  • ty check exits 0 in both CI environments

Checklist

• PR title follows Conventional Commits format
• All pre-commit checks pass (make pre-commit)
• No hardcoded strings in non-config/non-constants files
• No # type: ignore, cast(), Any, or object type hints (this removes ~30 existing ignores and adds none)
• No new comments or docstrings: a few short comments explain why, where the reason isn't visible in the code (MRO shadowing, the Neo4j module-name typing, the MSBL001 exclusion)

📝 Walkthrough

Walkthrough

The pull request updates graph and agent type contracts, parser behavior, tool handling, and runtime value checks. It also changes oracle dependencies and Dependabot rules, with tests covering these updates.

Changes

Graph query contracts and ingestion

Layer / File(s)	Summary
Graph query and result contracts codebase_rag/types_defs.py, codebase_rag/services/*, codebase_rag/graph_query.py, codebase_rag/graph_updater.py, evals/*	Query parameters use the PropertyParams mapping type, and query-result types allow list-valued properties. These types are applied across graph protocols, adapters, and evaluation helpers. FunctionLocations.update accepts mappings or iterable key/value pairs and converts input before writing.
Graph reads and parser configuration codebase_rag/graph_updater.py, codebase_rag/exceptions.py, codebase_rag/parsers/definition_processor.py, codebase_rag/tests/test_write_only_ingestor_reads.py, codebase_rag/tests/test_pre_parse_without_parser_query.py	GraphUpdater checks whether an ingestor supports reads before issuing graph queries. Pre-parsing skips missing query or parser entries. Tests cover write-only ingestors and incomplete parser configuration.
Typed graph entry points codebase_rag/cli.py, codebase_rag/graph_cli.py, codebase_rag/structural_check.py	Graph CLI and structural-check paths use typed ingestors instead of untyped objects and dynamic attribute lookup.

Parser and source transformation updates

Layer / File(s)	Summary
Language parsing and name extraction codebase_rag/parsers/*	Parser code updates language lookup, identifier extraction, export handling, node checks, and checker-facing dependency types.
Import splitting and indentation codebase_rag/editing/imports.py, codebase_rag/tests/test_import_rewrite.py	A shared indentation helper is used when split imports are emitted for Python, JavaScript/TypeScript, and Rust. Tests cover nested and top-level imports.
Parser boundary behavior and tests codebase_rag/parsers/ast_grep_tier.py, codebase_rag/parsers/csharp/type_inference.py, codebase_rag/tests/test_ast_grep_rule_parsing.py, codebase_rag/tests/test_java_variable_analyzer_integration.py	Selector-free ast-grep rules return no matches. C# inference distinguishes in-progress calls from cached results. Tests cover ast-grep rules and Java return-type fallback behavior.

Agent and MCP tool integration

Layer / File(s)	Summary
Agent and tool typing codebase_rag/services/llm.py, codebase_rag/mcp/tools.py, codebase_rag/prompts.py, codebase_rag/tools/shell_command.py, evals/agentic_qa.py, codebase_rag/tests/test_cgr_instructions.py, codebase_rag/tests/test_llm_service_unit.py	Agent and tool parameters and return values use concrete generic types. The evaluation graph-tool path also checks that an ingestor is present.
MCP tool invocation codebase_rag/mcp/tools.py	Registry calls obtain tool callables through _plain_function. Workspace wrappers treat a non-string project value as absent.
MCP response validation codebase_rag/mcp/client.py, codebase_rag/tests/test_mcp_update_and_search.py	The MCP client reads response text only when the first result item is TextContent. Tests cover text and image result items.

Runtime validation and typed boundaries

Layer / File(s)	Summary
Runtime value checks and narrowing codebase_rag/cli.py, codebase_rag/tools/semantic_search.py, codebase_rag/tools/code_retrieval.py, codebase_rag/gloss*.py, codebase_rag/decorators.py, codebase_rag/crash_correlation.py, codebase_rag/types_defs.py, codebase_rag/tests/*	Stats formatting, semantic search, source retrieval, and gloss handling check result values before using them.
Backend health and connection errors codebase_rag/constants/security.py, codebase_rag/tools/health_checker.py, codebase_rag/stack/health.py	Memgraph errors use a typed alias. Neo4j health checks load exception types from the configured exceptions module.
Decoder and Milvus output types codebase_rag/unixcoder.py, codebase_rag/vector_store.py, codebase_rag/tests/test_unixcoder_unit.py, codebase_rag/tests/test_vector_store.py	UniXcoder validates decoded values as strings. Milvus client keyword arguments use a TypedDict with optional token and database fields.

Oracle dependency configuration

Layer / File(s)	Summary
Oracle versions and update rules .github/dependabot.yml, codebase_rag/parsers/csharp_frontend/roslyn/Frontend.csproj, evals/oracles/*, codebase_rag/tests/test_dependabot_config.py	Dependabot groups Roslyn packages and ignores specified version ranges. The TypeScript and Rust oracle dependencies change, as do Roslyn package versions. The Rust oracle adjusts its trait-implementation tuple pattern.

Security Architecture Review

Security architecture risk: 🟡 Moderate · up to 1e0c0

An incomplete language configuration can cause a changed file to lose its previously indexed definitions while the update appears to succeed. This depends on a configuration mismatch; the agent and tool changes do not appear to grant new access.

Retained concerns

• Medium · reliability · inferred: For a previously indexed changed file whose language remains configured as parseable but has no query entry, pre-parsing now skips the file. The update can then delete its old subtree, emit only a generic File node, and treat the run as successful. Repeated updates may not restore the missing definitions without a subsequent reindex.

Security review details

Security Blast Radius

• inferred — The conditional integrity impact is on graph data for changed files under an affected language configuration, and consequently on consumers of that graph. The evidence does not establish a new tenant boundary, credential exposure, or privilege escalation.

Security Findings and Attack Paths

• inferred — A source-file change can encounter the silent graph-data loss only if a language is configured in parsers but missing from queries. The evidence does not show that an untrusted source author can cause that configuration mismatch; no independently exploitable attack path was verified.

Trust Boundaries and Controls

• observed — Graph-read capability checks retain exception fallbacks that avoid treating unreadable file ownership as permission to delete. The agent contract changes do not alter the inspected prompt-to-agent call or tool construction.

Resilience and Maintainability Implications

• inferred — Pre-parsing is the failure boundary intended to preserve old subtrees when parsing cannot complete. Treating a missing query entry as a successful skip weakens that containment for the newly handled case.

Hardening Proposals

• proposed — Before deleting a changed file's old subtree, distinguish an intentionally unsupported language from a configured language missing its query entry. Fail or defer that file's update in the latter case, and verify the full delete-and-rebuild recovery transition.
