Scope

What's changed:

• Added entitlement-driven history filtering for directus_activity and directus_revisions, so reads are automatically constrained by activity_history_days and revisions_history_days.
• Introduced a reusable history-query resolver that controllers and services use to merge license-derived date filters into incoming queries without replacing caller-provided filters.
• Applied revision-history limiting through the related activity timestamp, so revision reads inherit the same date window via activity.timestamp.
• Updated the activity feed UI to surface the current history window when a positive activity-history limit is present.
• Updated revisions-related UI and license usage display so reviewers can see history entitlements directly from the licensing screen.
• Added backend and frontend coverage around the new query filtering and messaging behavior.

Potential Risks / Drawbacks

• The filter-merging logic sits in the read path for two system collections, so regressions could show up as missing history or unexpectedly empty result sets.
• A zero-day entitlement now intentionally denies all results, which is a sharp behavior change and worth verifying against product expectations.
• Time-window filtering depends on server time and inclusive _gte semantics, so off-by-one-day behavior near boundaries is something to watch.

Tested Scenarios

• Added service tests for activity and revisions reads under different history-limit configurations.
• Added frontend tests for the activity route notice and the revisions sidebar detail behavior.
• Extended license-page coverage by surfacing the new history entitlements in the usage grid.

Review Notes / Questions

• Special attention should be paid to whether every history-facing endpoint should use the same limiter semantics as readByQuery.
• The new helper caches resolved queries per query object; that is intentional, but it is worth a quick sanity check for unexpected reuse patterns.
• Reviewer eyes on the product copy for limited history would help, since it now appears in both activity and licensing contexts.
