Settings & Model Catalog

# Configuration Directory Layout

Tacet stores settings, session logs, prompt history, and MCP definitions in the platform config directory:

• Unix / macOS: $XDG_CONFIG_HOME/tacet or ~/.tacet or ~/.config/tacet
• Windows: %APPDATA%\Tacet
• Configuration File: config.toml (contains default model package, theme settings, search provider)
• MCP Config: mcp.json (contains registered MCP server definitions)

# Standalone GGUF Vocabulary Tokenizer

`tacet-engine` includes a custom GGUF tokenizer that reads embedded vocabulary tensors directly from `.gguf` weight files without requiring external `tokenizer.json` files. This allows Tacet to load single-file model downloads seamlessly.

# Verified Default Catalog & Hardware Inference Floor

Before attempting model execution, Tacet performs binary capability checks to verify CPU vector extensions (AVX2, AVX512, NEON) and GPU acceleration backends (Metal, CUDA), preventing trade-offs of working engines for invalid downloads.
