+rem ============================================================
+rem  Cyrene v2 local embedding server (llama.cpp) - Windows
+rem
+rem  Usage:
+rem    scripts\embed.bat             start (default)
+rem    scripts\embed.bat start       start llama-server on :11434
+rem    scripts\embed.bat stop        stop llama-server
+rem    scripts\embed.bat status      show status
+rem
+rem  Serves an OpenAI-compatible embeddings endpoint:
+rem    POST http://127.0.0.1:<port>/v1/embeddings
+rem  backed by Qwen3-Embedding-0.6B Q8_0 (dim 1024, CPU) - the model
+rem  .env EMBEDDING_API_URL / EMBEDDING_MODEL are expected to point at.
+rem  Cyrene only takes the real semantic path when this is up; otherwise it
+rem  logs "vector index unavailable, falling back to in-memory semantic".
+rem
+rem  The vector index itself lives in PostgreSQL + pgvector (DB_PG_URL):
+rem    docker compose -f docker-compose.dev.yml up -d pg
+rem
+rem  Overridable via environment:
+rem    LLAMA_DIR    (default %USERPROFILE%\apps\llama.cpp)
+rem    EMBED_MODEL  (default %USERPROFILE%\.models\Qwen3-Embedding-0.6B-Q8_0.gguf)
+rem    EMBED_PORT   (default 11434)
+rem  Logs: %USERPROFILE%\llama.log (+ llama.stdout.log)
+rem
+rem  ASCII-only + CRLF on purpose (cmd parsing is codepage/line-ending
+rem  sensitive); Windows tools are called by absolute System32 path so an
+rem  MSYS/MinGW PATH (Git Bash) cannot shadow them.
