Symbiont v1.5.0
Highlights
LanceDB Embedded Vector Backend
Zero-config vector search using LanceDB — no Docker, no external services required. Qdrant is preserved as an optional backend behind the vector-qdrant feature flag.
Context Compaction Pipeline
Automatic context management with pluggable token counting (tiktoken + heuristic fallback), LLM-driven summarization (Tier 1), and last-resort truncation (Tier 4). Enterprise tiers gated behind feature flags.
Composio MCP Integration
Feature-gated SSE-based connection to Composio MCP server for external tool access.
Security Hardening
5 new structure-aware fuzz targets, trusted proxy configuration, fail-closed rate limiting, TOCTOU audit fix, and improved Vault secret detection.
Routing Engine Cleanup
Lock-free atomic routing statistics, SlmExecutor trait extraction, LLMClientPool registry pattern, and removal of 500+ lines of dead code including legacy SchemaPin CLI wrapper.
