Summary

AI summary

TelemetryBus.close() now correctly cleans up listeners by using named arrow functions.

Full changelog

Fixed

  • startServer edge interceptor returns server: null typed as Server. Changed type to Server | null, removeds any cast.
  • TokenEconomics overhead ratio reports 0 when ALL blocks are overhead. Now returns Infinity for 100% overhead.
  • ToolContract.materializeBehavior fingerprint condition gate included schema keys. Changed to check static rules only.
  • Static rules silently discarded when dynamic rules coexist. Composite fingerprint 'dynamic:' preserves static rule integrity.
  • TelemetryBus.close() uses wrong function reference for emoveListener. Named arrow function references for correct cleanup.

Tests

27 regression tests added across 4 new test files. Full suite: 4390 tests passing, 0 regressions.
