A short architecture article. The technical reference supports the topic; hypothetical scenarios and assessment proposals are editorial analysis, not accounts of personal implementations.

## The architecture decision

When one service calls another, application identity can obscure who initiated the operation. This complicates rules depending on users and resources.

## Practical application

Editorial proposal: trace a journey and mark where context is created, validated and propagated. For a hypothetical order, distinguish service authority from authorization to act on that order.

## How to verify

Test destination services through alternative paths with missing or inconsistent context. Record expected decisions and audit evidence. Avoid implicit trust in every internal call and preserve accountability across teams.
