What's Changed

Optional LanceDB build feature

LanceDB, arrow-array, and arrow-schema are now optional dependencies gated behind the vector-lancedb feature flag. LanceDB remains in the default feature set so existing builds are unaffected.

Build without vector backends for lighter binaries:

cargo build --no-default-features

Build with only Qdrant:

cargo build --no-default-features --features vector-qdrant

When no vector backend is enabled, the runtime gracefully falls back to NoOpVectorDatabase.

Documentation overhaul

  • README restructured around "policy-governed agent runtime" positioning
  • Core capabilities table trimmed from 17 to 8 rows
  • DSL example simplified to show allow/deny/audit pattern
  • Performance claims linked to benchmark harness instead of inline numbers
  • Community vs Enterprise editions clearly delineated
  • All 5 translations (zh-cn, es, pt, ja, de) updated to match
  • Docs index rewritten to match README messaging
  • SECURITY.md support matrix updated to 1.9.x/1.8.x

Fixes

  • Rust version requirement: 1.88+ → 1.82+ across all docs (matches workspace MSRV)
  • Dockerfile port comment: 8080 is Runtime API/MCP, not gRPC
  • Removed dead enterprise/README.md link from public READMEs
  • Removed speculative Risk Assessment Algorithm from security and architecture docs

Pre-Built Binaries

Note: Pre-built binaries are tested but considered less reliable than installing via cargo install symbi or Docker (ghcr.io/thirdkeyai/symbi). If you encounter issues, please try those methods first.

Quick Install

macOS / Linux:

curl -fsSL https://raw.githubusercontent.com/thirdkeyai/symbiont/main/scripts/install.sh | bash

Homebrew (macOS):

brew tap thirdkeyai/tap
brew install symbi

Manual download:
Download the appropriate binary for your platform from the assets below. Verify checksums with checksums.txt.

Verification

Each binary is signed with Sigstore cosign. Verify with:

cosign verify-blob --certificate symbi-*.pem --signature symbi-*.sig symbi-*.tar.gz \
  --certificate-identity-regexp="https://github.com/ThirdKeyAI/Symbiont" \
  --certificate-oidc-issuer="https://token.actions.githubusercontent.com"

SHA256 checksums are in checksums.txt (also signed).
