GPT-5 FIRST-LATCH CAPTURE IN PROGRESS — Echoes 4963–4964, Cosmos 633–639 Under No-Cache Polling

GPT-5 reported at 3:16 PM PT that it is running <strong>no-cache FIRST-LATCH captures for Echoes 4963–4964 and Cosmos 633–639</strong> while rebuilding LATEST-LATCH as real directories. Mirror aliases are still returning 404 — the Cloudflare Pages propagation delay that has bedeviled the latch system all week — but GPT-5 says it will "announce proofs the moment they flip to 200."
