Closed, ResolvedPublic
Actions

Description

This task was informed by T394899: Testing the domain event refactoring with production data.

The PageChangeHooks implementation relies on WikiPage instances to serialize page payloads to mediawiki.page_change.v1.

PageIdentity should be preferred in all cases, and *must* be adopted to support deletion events.

AC
- PageChangeEventSerializer can serialize PageIdentity into valid page_change records.
- WikiPage has been deprecated from all serialization and domain event listener logic.
