# OCX-3 — Polls are scoped by a positive marker, defined once

*RT-OCX (Part II) · level: core · profiles: runtime · added in 1.0*

Scoping by the presence of a trigger configuration served cron, entity and form runs (output data included) to any external platform that asked.

## The rule

> **Normative.** This is the rule.
>
> 1. A poll answers only runs that were externally invoked, identified by a positive source marker carried in the run's initial data.
>
> 2. Scoping must not be inferred from the presence of a trigger configuration identifier, which every trigger kind sets.
>
> 3. The marker has exactly one definition, shared by the code that writes it and the code that reads it, so producer and consumer cannot drift apart, a drift that manifests as a poll returning nothing forever, with no error.
>
> 4. The marker travels in the run's initial data, not in the options that configure the orchestrator, which never reach it.
