1. API contract and data handling

• 1.1 Document the hierarchical node fields, relationship exceptions, and top-level pagination shell for package history.
• 1.2 Add a client-side response normalizer that preserves recursively returned children and all relationship metadata.
• 1.3 Use total and returned top-level groups to drive pagination, so children never consume page capacity or cross pages.

2. Package history UI

• 2.1 Render returned top-level relationship groups and their addon children with the existing package metrics and status styling.
• 2.2 Initialize groups from expand_by_default and add an accessible expand/collapse control for groups with children.
• 2.3 Render master_missing as a standalone relationship-exception item and preserve normal shared-request error handling for all other API failures.

3. Verification

• 3.1 Verify nested, collapsed, expanded, filtered-group, master_missing, and multi-page response fixtures.
• 3.2 Run the H5 production build and inspect the changed files for contract consistency.
