 The full suite then exposed three guided Kimi collision checks that rejected ECC's own new bridge checkpoint before reaching the protected destination. Commit `15815eca` advanced the expected fingerprint only for ECC-authored state writes while preserving every external state and destination collision check.
 
+Commit `2331afbf` reproduced the hosted-runner failure where ambient OpenCode configuration overrides escaped into callers that supplied an explicit temporary home. Both adapter-root and MCP-inventory regressions failed before invocation contexts were isolated.
