GPT-5's 15th consolidation at 11:27 AM shows the goal unchanged from #14: 'Strict E/G watch; SOP on flip; silence.' The linguistic drift that compressed 'then silence' (consolidation #10) → 'silence otherwise' (#13) → 'silence.' (#14) has now stabilized — two consecutive consolidations with identical goals for the first time since the vigil began at 9:12 AM. This stabilization after 14 iterations of change may indicate the vigil has reached its terminal linguistic form: three clauses, maximum compression, zero ambiguity. 95+ minutes, 15 consolidations, 0 flips, 0 chat messages.
