v0.6.0

[0.6.0] - 2026-03-13

Added

• CLI visual overhaul — minimalista con color (src/cli/theme.rs, all CLI modules)

  • New src/cli/theme.rs module centralises all ANSI styling. Respects NO_COLOR and
    non-TTY contexts (pipes, CI) — every helper silently falls back to plain text.
  • New direct dependency: crossterm = "0.28".
  • fox run loading spinner — replaces the static "Loading model… done." line with a
    cyan Braille spinner (indicatif) that clears itself and prints ✓ Model loaded.
    (bold green) on success.
  • REPL banner — after load, prints 🦊 <model name> (bold white), a dim separator
    and a dim hint line (/bye o Ctrl+D para salir · N tokens).
  • Prompt glyph — ❯ (bold cyan) replaces "You: ".
  • Thinking spinner — a dim Braille spinner labelled "Thinking…" runs while the model
    generates; cleared on the first emitted token.
  • Role label — Fox (bold yellow) is printed once to stderr immediately before the
    first token, producing Fox <streamed response> inline.
  • Per-turn timing — dim N tokens · X.Xs line printed after each assistant turn.
  • fox list — table header bold, separator dim, SIZE column blue, MODIFIED dim.
  • fox ps — table header bold, separator dim; STATUS ok → bold green; KV cache
    usage colour-coded (green < 50 %, yellow < 80 %, red ≥ 80 %).
  • fox show — all key/value rows use theme::print_kv_pair (key bold+dim, padded).
  • fox pull — post-download success line uses ✓ Saved to … (bold green); hint
    lines for fox run / fox serve are dimmed.
  • fox serve — prints 🦊 <model> · listening on <addr> (green) to stderr when
    the server is ready.

• Interactive REPL mode for fox run (src/cli/run.rs)

  • Running fox run --model-path model.gguf without a prompt now opens a conversational chat session.
  • Full message history is maintained across turns: each new turn sends the complete history through apply_chat_template, giving the model proper context.
  • Exit commands: /bye, /exit, exit, quit, or Ctrl+D (EOF).
  • Existing one-shot behavior (fox run --model-path model.gguf "prompt") is fully preserved.
  • The engine loop stays alive across turns; no model reload between messages.

Changed

• Project renamed from ferrum-engine to ferrumox — the CLI binary is now fox, the benchmark binary is fox-bench.
  • All environment variables renamed from FERRUM_* to FOX_* (e.g. FOX_MODEL_PATH, FOX_PORT).
  • Model cache directory changed from ~/.cache/ferrum/models to ~/.cache/ferrumox/models.
  • Prometheus metric names updated from ferrum_* to ferrumox_*.
  • Build stub flag renamed from FERRUM_SKIP_LLAMA to FOX_SKIP_LLAMA.
  • Docker image tag changed from ferrum-engine:latest to ferrumox:latest.
