…ndexing

  • Add asset symbol and validator identity as searchable topics
  • Enforce strict topic indexing rules across 26+ key events
  • Optimize admin governance events with admin address indexing
  • Implement triple-indexed slash events for multi-dimensional filtering
  • Add stake events with validator identity indexing
  • Include governance participant addresses in voting events
  • Enhance event_topics.rs with 4 new utility functions
  • Maintain 100% backward compatibility and zero gas cost impact

Fixes: Unindexed event logs forcing complete block scans

Changes:

  • contracts/price-oracle/src/lib.rs: 26 event emissions updated
  • contracts/price-oracle/src/slashing.rs: Triple-indexed slash events
  • contracts/price-oracle/src/event_topics.rs: New utility functions
