The operating core is sovereign. SIGNAL Credits are a courtesy, never a cage.
Most SaaS gates capability behind a subscription. We don't. Every engine, every pattern, every Trust Mark tier is available at $0. SIGNAL Credits buy optional AI polish — your business runs end-to-end without spending a credit.
Credits expire when? Never.
Credits do not buy the cycle, the diagnostic, the pattern selection, the catalog hydration, the Trust Mark, the spine reminders, the Today Board, or the override rights. Those are free, forever.
Credits sharpen tone on outputs the system already produced.
Free-model copy unavailable while the engine reconnects. The $0 capability floor still applies.
The Free Gate tier is free, permanently, and you do not need a credit card to start. The Free Gate is $0 forever. No credit card is required.. Paying for a higher tier buys more volume and more leverage — it never unlocks a capability we were holding back.
