Moved the search and embedding stack further toward the Simeon backend, including PHSS vector search support, topology and clustering work, and continued removal of legacy HNSW paths. - Improved write-path coordination, repair and rebuild behavior, and daemon readiness under load. - Added storage health checks, corruption detection, and broader instrumentation and tuning for memory-constrained systems. ### Breaking Changes - Embeddings no longer center on ONNX Runtime by default. YAMS now prefers the lighter Simeon path, which reduces resource usage but requires AVX or NEON support. - ONNX Runtime support was later reinstated as an alternate path, but Simeon remains the default direction in this release. ### Notable Fixes - Fixed daemon status and readiness regressions, SocketServer loop fragility, MCP router issues, and DB optimize repair handling. - Reduced memory pressure in repair and search paths and tightened batching for topology and rebuild work. - Cleaned up release and packaging regressions, including build-artifact leakage and platform-specific CI issues that affected release confidence. ### Security - Expanded Opengrep coverage and addressed storage correctness, underflow-related bugs, and repair subsystem scanning issues. - Tightened related hook and script behavior used in repo security checks. ### Performance - Improved idle memory reclamation, ingestion throughput, startup behavior, and compressed R2 transport behavior. ### Full Details - See `CHANGELOG.md` in this PR for the full commit-level history. --- This PR was generated with [Release Please](https://github.com/googleapis/release-please).
