Executive summary
A fresh status review verified that Hiro's narrow Stage 6B evidence-only promotion lane is implemented and passes both its focused policy suite and the complete repository suite on revision 83902be5399cb4d90b95fb39422f2c9f126f1220.
The focused Stage 6 suite passed all 47 tests in 39.26 seconds, and the full repository suite passed all 414 tests in 133.21 seconds during this session.
Stage 6B remains deliberately inactive: the compiled feature default is false, the persistent DISABLED sentinel is present, the activation environment value is absent, no user enablement packet exists, and the real runner exits before scanning the candidate inbox or attempting a promotion.
The remaining gate is governance rather than missing implementation: present the exact bounded activation packet and obtain separate explicit user approval before changing any activation control.
Stage 6C remains undesigned and unauthorized. Stage 6B readiness does not authorize runtime or existing-file self-modification.
