v0.2.0

[0.2.0] - 2026-07-23

Added

• Production semantic analysis for Go, Java, Kotlin, C#, Python, Rust, Swift,
  TypeScript/TSX, JavaScript/JSX, PHP, C, and C++.
• Typed CALLS, EXTENDS, IMPLEMENTS, OVERRIDES,
  METHOD_IMPLEMENTS, and DISPATCHES_TO relationships with cross-file
  resolution.
• Repository-scoped symbol search, source search, semantic vectors, hybrid
  retrieval, bounded graph traversal, and shortest paths.
• code, docs, and all source-search scopes.
• context symbol intelligence with source excerpts and typed direct
  relationships.
• impact reverse semantic dependency analysis with depth, confidence, and
  relationship details.
• check graph integrity, inheritance-cycle, import-cycle, and optional
  low-confidence relationship analysis.
• diff Git changed-line mapping to persisted symbols with aggregated impact
  and change causes.
• Non-mutating rename planning with identifier validation, conflict
  detection, semantic references, and exact textual candidates.
• Deterministic parser-inspection CSV and complete persisted-graph CSV export.
• Public Go Engine APIs for all supported library capabilities.
• Single-word CLI commands and matching stdio MCP tools.

Changed

• Rebuilt ingestion around one production analysis path shared by the Go
  library, CLI, and MCP.
• Isolated graph, symbol, source, and vector data per repository.
• Repository replacement now builds and atomically publishes a complete
  snapshot before retiring the previous snapshot.
• MCP is hosted by the CLI adapter and invokes only public Engine methods.
• Traversal results now include edges, relationship types, directions,
  confidence, and resolution reasons.
• Source search defaults to code and engineering configuration instead of
  unrestricted repository text.
• Updated README architecture diagram and English and Chinese user guides for
  the current engine capabilities.

Fixed

• Improved cross-file calls, interface implementations, inheritance, and
  method override resolution across all supported languages.
• Restored PHP Composer namespace, inheritance, implementation, override, and
  call resolution on large framework repositories.
• Fixed Go interface method sets and cross-file call chains.
• Fixed C# generic inheritance and explicit override handling.
• Fixed Python named imports and default-argument calls, Rust workspace
  imports, Swift package visibility and generic constraints, and C/C++ symbol
  resolution.
• Removed dangling community memberships, self imports, invalid self semantic
  relationships, and relationships with missing endpoints.
• Prevented one repository from locking unrelated repository data.
• Added a portable Windows source-search backend while preserving the public
  search behavior.

Removed

• Removed the obsolete community, ingestion, route, wiki, group, collection,
  and incremental-index implementations replaced by the production engine.
• Removed analysis-mode branching; language tuning now uses the single
  production path and optional local CSV validation.
