## [v0.7.11] - Unreleased

### Added
- MCP `graph` tool for knowledge graph queries (parity with CLI `yams graph`).
- Graph: snapshot-scoped version nodes, `contains` edges for file→symbol, `--dead-code-report`.
- Graph prune policy (`daemon.graph_prune`) to keep latest snapshot versions.
- Download CLI: progress streaming (human/json) via DownloadService callbacks.
- Symbol-aware search ranking: definitions rank higher than usages (`YAMS_SYMBOL_WEIGHT`).
- Zig language support: functions, structs, enums, unions, fields, imports, calls.

### Performance
- IPC latency reduced from ~8-28ms to ~2-5ms (connection pooling, async timers, cached config).
- Post-ingest throughput: dedicated worker pool, adaptive backoff, batched directory ingests.

### Fixed
- Compression stats now persist across daemon restarts (`Storage Logical Bytes` vs
  `CAS Unique Raw Bytes` now show correct values).
- CLI rejects ambiguous subcommands (e.g., `yams search graph` → use `--query`).
- `--paths-only` search now returns results correctly.
- `yams watch` waits for daemon ready; always ignores `.git` contents.
- Expanded prune patterns for build artifacts and language caches.
- Fixed ONNX model loading deadlock on Windows (single-flight pattern, recursive mutex).
- Streaming: 30s chunk timeout, backpressure stops producer on queue overflow.
- `yams add` returns immediately; hash computed async during ingestion.
- Replaced experimental Boost.Asio APIs with stable `async_initiate` (fixes TSAN races).
