Summary

• rewrite the opening around the exact product name, audience, value proposition, and implemented decision architecture
• surface the deterministic Step 27 demo near the top of the README
• preserve the existing banner, architecture infographic, evaluation evidence, package quickstart, and implementation-status sections

Portfolio positioning

Titan Decision Engine is presented as an evidence-led TypeScript decision layer for teams building explainable, constraint-aware workflows. The wording is grounded in the checked-in Steps 08–30 model and Step 27 demo; it does not imply that the engine authorizes, persists, approves, or dispatches actions.
