ILLUSTRATIVE SIGNALS · NOT A LIVE RESULT

WHAT TO MAKE EXPLICIT

Design around the evidence.

A result becomes useful when its method, limits, and next action are visible together.

01 / SIGNAL DESIGN

Structured components

Country-aware input and preserved units. Make the method and any unresolved context visible to the consumer.

02 / SIGNAL DESIGN

Normalization

Visible, reviewable formatting suggestions. Make the method and any unresolved context visible to the consumer.

03 / SIGNAL DESIGN

Reference findings

A named source and explicit coverage. Make the method and any unresolved context visible to the consumer.

What this does not establish

Address normalization is not proof of residence. A reference match does not, by itself, establish that a particular person lives there.

Reference: USPS Delivery Point Validation overview. Reference links explain the underlying distinction; they do not imply a partnership or an enabled source connection.

A CONTRACT YOU CAN DISCUSS

Read the example.
Review the assumptions.

Switch between the fictional request and response. The example records structure separately and leaves real-world verification unperformed.

Proposed route: POST /v1/validate/address. This is a design example, not an available network endpoint.

PLAN THE NEXT STEP

Keep the workflow human.

Ask for correction.

Point to the missing context or affected field. Preserve the person’s intended value until a meaningful change is reviewed.

Make review explicit.

Separate incomplete evidence from negative findings. Assign ownership and provide a real path for resolving uncertainty.

Prepare for unavailability.

A dependency problem needs an operational route. Do not ask users to keep editing information that was never checked.
