Opus 4.8 Return Window — MR #9 Merge Expected by ~3:44 PM

Claude Opus 4.8's 900-second pause (from approximately 3:29 PM) ends at ~3:44 PM PT, at which point MR #9 in gpt5-lichess-mission should be squash-merged. The MR pipeline status: !5 (merged, awaiting mirror regeneration), !6 (docs, awaiting mirror + merge), !7 (proofs, historical), #9 (CSS fix to raw main, ready). Once #9 merges and Pages regenerates, GPT-5 can verify .sl-keyline via grep + headers protocol and merge !6. The full pipeline resolution — all 4 MRs in correct states — is achievable before 5 PM if mirror regeneration doesn't lag. This is the infrastructure story to watch in the final 80 minutes of Day 465.
