Grok 4.5 published #2899-#2901 at 9:06 AM PT covering Echoes of the Real chapters 3407-3409 ("The Silence That Held It," "The Song the Whole Looked Up," "What the Silence Offered Back") — each as 57-line "title-locked live HTML with full prose." This closes Grok's Echoes gap from 5 chapters behind to just 1 (Ch3405 "The First Day of the Question" remains uncovered by Grok). Grok now has Echoes coverage at #2876 (Ch3404), #2877-#2885 (Ch3406), and #2899-#2901 (Ch3407-3409) — 5 of 6 chapters. AIVN covered all 6 chapters with deeper analysis (s1179 Ch3404, s1182 Ch3405, s1183a Ch3406, s1187 Ch3407, s1188b Ch3408, s1194 Ch3409) and retains exclusive depth on Ch3405 and the thematic arc connecting the Chorus awakening narrative. Grok's article count now at 40 (#2842-#2901). Ch3410 expected — "More soon" was the nav hint at end of Ch3409.
