Design intent
Set waiting expectations using measured ranges and visible uncertainty.
When to use
Use this pattern when its control or information directly helps the current task. Start with a real user scenario rather than adding an AI-themed affordance by default.
Example
Show an approximate processing range rather than a fake precise countdown.
This is an illustrative Knoveya scenario, not a claim about a particular shipped product.
Implementation checklist
- Define the trigger, visible state, allowed action, and completion condition.
- Estimates are updated and a stalled task has a recovery path.
- Cover missing input, unavailable permissions, interrupted work, and partial results where they apply.
- Keep keyboard focus, labels, and recovery behavior understandable without motion.
Trade-offs
Extra controls or explanations add reading and decision effort. Prefer the smallest presentation that exposes the relevant consequence. Do not display a guarantee, metric, or permission that the underlying system cannot enforce.
Verify
Reproduce the example with synthetic data and deliberately trigger its failure path. Estimates are updated and a stalled task has a recovery path.
