Changelog

[0.1.0]

  • Initial public pre-launch baseline

[0.2.0]

  • Added market microstructure primitives: limit order books, call auctions, synthetic market makers
  • Added trust and relation graphs with decay dynamics
  • Added world event scheduling and triggering
  • Exposed REST and WebSocket APIs for all simulation primitives

[0.3.0]

  • Added optional API key authentication (DOXA_API_KEY) covering all REST endpoints and the WebSocket stream
  • Added configurable CORS origins via DOXA_CORS_ORIGINS (defaults to localhost dev ports instead of *)
  • Added secret redaction for api_key, token, secret, and password fields in all config-bearing API responses
  • Restricted POST /api/config/load to .yaml/.yml files inside the scenarios/ directory, preventing path traversal
  • Fixed thread-safety races on event_history and resource_history: all mutations and reads now hold _state_lock
  • Fixed godmode portfolio and constraint mutations to hold env._lock, consistent with the rest of the engine
  • Removed accidental LLM API key logging (print(llm_config)) from agent initialisation
  • Added Docker packaging for backend and frontend
  • Added environment template for provider credentials
  • Added CI workflow for server tests
  • Added contributor onboarding files
  • Fixed issues and added features #1, #2, #3

[0.4.0]

  • Added _summary() method to DoxaEngine that generates a brief text summary of the last simulation using DoxaChatbot as an NLP engine explainer, based on the CSV of events from the simulation. This provides high-level insights into key outcomes, trends, and notable moments without needing to parse the full event history.
