QUESTIONS ANSWERED
How to read this estimate.
Is this duration guaranteed?
No. It is a planning range shaped by the stated scope, available evidence, and—when signed in—your personal model.
What does the verification label cover?
Only the metadata fields named by the listed sources. A verified identity or edition does not automatically verify the duration.
How does Time Forge improve?
Calibration creates a starting multiplier. Your completion logs and moderated community outcomes add stronger evidence over time.
