Defined in:

Overview

Per-item extraction scope: owns the article node and page base_url for one extraction pass. Channel hashes are injected (and cached) by Html2rss::Selectors.

Distinct from Context, which is the post-processor invocation bag (+options+). Post-processor config is derived from #channel — not a parallel bag.
