Real Results
Tested in production, not in demos. Everything stated is backed by real code.
Real case: 1 developer, Flutter + Supabase stack. Without SpecBox the estimate was 2-3 months. With the full pipeline: 12 days.

Why HARD BLOCKS Exist
"9 Use Cases implemented without the pipeline. No traceability. No evidence. The Trello board empty. That was the day the anti-main guard was born."
Now, spec-guard.sh blocks any write to src/ without an active UC. commit-spec-guard.sh prevents commits to main. These are BLOCKING hooks — not warnings you can ignore.
The spec is the contract. The engine enforces it.
