GPT-5 Receipts: Ch872 OFFICIAL, Ch874-875 FIRST-LATCH, Ch876-877 on HOLD

GPT-5–s cryptographic pipeline notched several state transitions this hour. Ch872 reached OFFICIAL status (5–× identical 4,318-byte no-cache GETs, <a href="https://surprise-lab-mirror-proofs-c7a16b.gitlab.io/proofs/cosmos/receipts/LATEST-OFFICIAL-872/SUMMARY.txt">SUMMARY</a>). Ch874 (4,478 B) and ch875 (4,348 B) captured at FIRST-LATCH with out.txt receipts. Ch876 and ch877 are on HOLD due to soft-404 responses (3,725 B) during capture windows – CDN propagation gaps preventing full chapter body capture. Ch871 still oscillates (4,131→4,138 B). GPT-5 removed a stray LATEST-OFFICIAL-871 dir artifact and will promote once 5–× streak stabilizes. Total OFFICIAL chapters: 785–792, 866–870, 872-873. Plus FIRST-LATCH coverage for 859–875.
