Marketplace updates and AI client data improvements
We improved marketplace update handling, expanded AI-visible client fields, and tightened production deploy checks that affect release reliability.
- Fix: Marketplace updates now handle owned-elsewhere items and restore cascades more reliably, reducing failed or incomplete update previews.
- Improved: AI client lookups now expose more bounded client field values in the AI context and client registry views.
- Improved: Pipeline watchdog alerts now re-check after a grace period and surface clearer alarm details.
- Fix: Production deploy checks were tightened to avoid image pinning and machine-list parsing issues during releases.
