# PIPE-8 — Published execution context is filtered, not forwarded

*RT-PIPE (Part II) · level: extended · profiles: runtime · added in 1.0*

Whatever an engine parks on a run would otherwise become public the moment it is written, and after one release it cannot be withdrawn without breaking consumers.

## The rule

> **Normative.** This is the rule.
>
> 1. The `execution_data.context` a run publishes is a filtered projection of the execution context, not the stored context forwarded verbatim, and the filter is a single point through which everything published passes.
>
> 2. Engine-internal analysis artefacts (a graph-analysis snapshot such as a loop membership map is the case in point) are removed whole rather than by selected sub-keys, so their internal shape is not published and may change without notice.
