August 2025 saw a focused stability improvement in defisaver-positions-sdk by removing expired Pendle assets from STAKING_ASSETS to prevent stale APY data. This bug fix ensures APY metrics reflect only active assets, reducing noise in dashboards and downstream analytics, and lowering unnecessary data fetches. Impact: data integrity improved for yield dashboards, with more reliable APY reporting for users and partners. The change minimizes API calls for deprecated assets and reduces risk of stale analytics skewing decisions. Scope: small, targeted fix with low surface area, using the existing asset lifecycle logic.
