- in code: code-level context

- in commits: changeset-level context

- in jira: if you need to provide changeset-level context, point them to the MR/commit log

- in confluence: high-level documentation

- in daily standups: status update; if you need to provide changeset-level context, point them to the MR/commit log

- in release notes: generate automatically from commit log

IMO duplication in documentation should be treated the same as in code – it should be avoided as much as possible.
