### Fixed
* download logic improvements and ci test fixes. Stagging download fixes seperate from search features ([2d5c662](https://github.com/trvon/yams/commit/2d5c6625eb4e794c878441bb052911baf91169e0))

## [0.14.0](https://github.com/trvon/yams/compare/v0.13.1...v0.14.0) (2026-05-04)
### Highlights
- 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.
