* Add support for non-ASCII characters in LLM prompts
- Add ensure_ascii parameter to Graphiti class (default: True)
- Create to_prompt_json helper function for consistent JSON serialization
- Update all prompt files to use new helper function
- Preserve Korean/Japanese/Chinese characters when ensure_ascii=False
- Maintain backward compatibility with existing behavior
Fixes issue where non-ASCII characters were escaped as unicode sequences
in prompts, making them unreadable in LLM logs and potentially affecting
model understanding.
* Remove unused json imports after replacing with to_prompt_json helper
- Fix ruff lint errors (F401) for unused json imports
- All prompt files now use to_prompt_json helper instead of json.dumps
- Maintains clean code style and passes lint checks
* Fix ensure_ascii propagation to all LLM calls
- Add ensure_ascii parameter to maintenance operation functions that were missing it
- Update function signatures in node_operations, community_operations, temporal_operations, and edge_operations
- Ensure all llm_client.generate_response calls receive proper ensure_ascii context
- Fix hardcoded ensure_ascii: True values that prevented non-ASCII character preservation
- Maintain backward compatibility with default ensure_ascii=True
- Complete the fix for issue #804 ensuring Korean/Japanese/Chinese characters are properly handled in LLM prompts
* Prepare code
* Fix tests
* As -> AS, remove trailing spaces
* Enable more tests for FalkorDB
* Fix more cypher queries
* Return all created nodes and edges
* Add Neo4j service to unit tests workflow
- Introduced Neo4j as a service in the GitHub Actions workflow for unit tests.
- Configured Neo4j with appropriate ports, authentication, and health checks.
- Updated test steps to include waiting for Neo4j and running integration tests against it.
- Set environment variables for Neo4j connection in both non-integration and integration test steps.
* Update Neo4j authentication in unit tests workflow
- Changed Neo4j authentication password from 'test' to 'testpass' in the GitHub Actions workflow.
- Updated health check command to reflect the new password.
- Ensured consistency across all test steps that utilize Neo4j credentials.
* fix health check
* Fix Neo4j integration tests in CI workflow
Remove reference to non-existent test_neo4j_driver.py file from test command.
Integration tests now run via parametrized tests using the drivers list.

* Add OPENAI_API_KEY to Neo4j integration tests
Neo4j integration tests require OpenAI API access for LLM functionality.
Add the secret environment variable to enable these tests to run properly.

* Fix Neo4j Cypher syntax error in BFS search queries
Replace parameter substitution in relationship pattern ranges (*1..$depth)
with direct string interpolation (*1..{bfs_max_depth}). Neo4j doesn't allow
parameter maps in MATCH pattern ranges - they must be literal values.
Fixed in both node_bfs_search and edge_bfs_search functions.

* Fix variable name mismatch in edge_bfs_search query
Change relationship variable from 'r' to 'e' to match ENTITY_EDGE_RETURN
constant expectations. The ENTITY_EDGE_RETURN constant references variable
'e' for relationships, but the query was using 'r', causing "Variable e
not defined" errors.

* Isolate database tests in CI workflow
- FalkorDB tests: Add DISABLE_NEO4J=1 and remove Neo4j env vars
- Neo4j tests: Keep current setup without DISABLE_NEO4J flag
This ensures proper test isolation where each test suite only runs
against its intended database backend.

* fix: remove global DEFAULT_DATABASE usage in favor of driver-specific
config
Fixes bugs introduced in PR #607. This removes reliance on the global
DEFAULT_DATABASE environment variable. It specifies the database within
each driver. PR #607 introduced a Neo4j compatability, as the database
names are different when attempting to support FalkorDB.
This refactor improves compatability across database types and ensures
future reliance by isolating the configuraiton to the driver level.
* fix: make falkordb support optional
This ensures that the the optional dependency and subsequent import is compliant with the graphiti-core project dependencies.
* chore: fmt code
* chore: undo changes to uv.lock
* fix: undo potentially breaking changes to drive interface
* fix: ensure a default database of "None" is provided - falling back to internal default
* chore: ensure default value exists for session and delete_all_indexes
* chore: fix typos and grammar
* chore: update package versions and dependencies in uv.lock and bulk_utils.py
* docs: update database configuration instructions for Neo4j and FalkorDB
Clarified default database names and how to override them in driver constructors. Updated testing requirements to include specific commands for running integration and unit tests.
* fix: ensure params defaults to an empty dictionary in Neo4jDriver
Updated the execute_query method to initialize params as an empty dictionary if not provided, ensuring compatibility with the database configuration.

- Replaced MyPy with Pyright in configuration files and CI workflows.
- Updated `pyproject.toml` and `uv.lock` to reflect new dependencies and versions.
- Adjusted type hints and fixed minor code issues across various modules for better compatibility with Pyright.
- Added new packages `backoff` and `posthog` to the project dependencies.
* Update CI workflows to install all extra dependencies for type checking and unit tests
* Update dependencies in uv.lock to replace MyPy with Pyright and add nodeenv package. Adjust type hinting in config.py for compatibility with Pyright.
