Removes the zep-cloud dependency entirely and replaces it with a
local file-based graph store (LocalGraphStore) that persists nodes,
edges, and episodes as JSON files under uploads/graphs/{graph_id}/.
- Add backend/app/utils/local_graph_store.py: thread-safe JSON store
with keyword search, node upsert, and episode append
- Rewrite graph_builder.py: LLM-based entity/relationship extraction
from text batches, stored locally instead of sent to Zep Cloud
- Rewrite zep_graph_memory_updater.py: agent activities written as
episodes + searchable fact edges in local JSON
- Rewrite zep_entity_reader.py: reads nodes/edges from local JSON
- Rewrite zep_tools.py: keyword search on local JSON replaces
Zep semantic search; _local_search is now the primary path
- Update oasis_profile_generator.py: local store replaces Zep client
for entity context enrichment
- Update ontology_generator.py: generated code template uses
pydantic BaseModel instead of Zep EntityModel/EdgeModel
- Convert zep_paging.py to a no-op stub (pagination not needed)
- Remove ZEP_API_KEY from config.py, add GRAPH_STORAGE_DIR
- Remove ZEP_API_KEY guards from api/graph.py and api/simulation.py
- Remove zep-cloud==3.13.0 from requirements.txt and pyproject.toml

- Introduced the Report Agent module to facilitate the automatic generation of simulation analysis reports using LangChain and Zep, following the ReACT model.
- Added functionality for report outline planning, segmented content generation, and user interaction through a dialogue interface.
- Implemented new API endpoints for report generation, status checking, and retrieval, enhancing the overall reporting capabilities.
- Updated README.md to include detailed instructions on the new report generation features and API usage.
- Enhanced the project structure to accommodate the new report management functionalities, including report storage and retrieval mechanisms.
- Added support for a `max_rounds` parameter in simulation API, allowing users to limit the number of simulation rounds, improving control over simulation duration.
- Updated README.md to reflect the new `max_rounds` parameter and its usage in simulation requests.
- Enhanced error handling for `max_rounds` input validation to ensure it is a positive integer.
- Modified simulation runner and related scripts to incorporate `max_rounds` functionality, ensuring consistent application across Twitter and Reddit simulations.
- Improved logging to indicate when the number of rounds is truncated due to the `max_rounds` setting, enhancing traceability during simulation execution.
- Updated README.md to include new simulation scripts and configuration details for OASIS, including API retry mechanisms and environment variable settings.
- Added simulation management and configuration generation services to streamline the simulation process across Twitter and Reddit platforms.
- Introduced new API routes for simulation-related operations, including entity retrieval and simulation status management.
- Implemented a robust retry mechanism for external API calls to improve system stability.
