Three-step flow

How it works

Read current public company-level facts for an explicit watchlist.
Store one named baseline and compare watched fields on later runs.
Emit observed changes and source failures for downstream review.

Copyable starting point

Example input

{
  "companyNumbers": ["02050399"],

}

Decision boundary

No officer or PSC profiles, birthdays, or private databases.
Does not predict insolvency or provide a credit or legal decision.
A first baseline is setup evidence, not a warning.
Source failures are visible and are not billed as successful checks.
Check the current Store price in your own account before scheduling.
