Community in practice

Small observations.
Shared understanding.

Useful change begins with people noticing, asking questions and sharing what they can document. Community work gives those contributions a careful path to review.

How to contribute
  1. 01

    Notice & document

    Keep the listing link, product identifiers, date and what you actually observed.

  2. 02

    Review with care

    Separate observations, source evidence and inference. A signal is a starting point for review.

  3. 03

    Learn & prevent

    Support proportionate action and better guidance. Correct the record when new evidence changes the picture.
