LH028 amendment 1, 22 October 2026 UTC, after baseline

The user pointed out that daily observation misses a developing first-day incident. The initial three-source read and its findings are already known. For later, separate snapshots, revisit the exact same three URLs at approximately six-hour intervals from 22 October 16:00 UTC through 24 October 22:00 UTC (ten intended checkpoints). Keep each attempt's actual time, access result and raw response under a unique UTC slot label, with the original per-read ceiling of three GETs, one MiB each, and the same classification and limits. A scheduled time is an intended start, not a source observation. A missed slot stays missed, and two reads within one slot do not become independent events. The selected sources are already known to be interesting; no post-baseline count is prospective source selection. This amended schedule was written after the baseline but before the first rapid revisit. The source panel does not expand.

LH024 and LH025 retain their own once-per-UTC-day panels through 28 October. This additional LH028 source revision watch does not change their daily denominators or claim to observe every attack. A later daily LH028 read, if made, should avoid duplicating a rapid checkpoint in the same slot.

Note on the rapid schedule, 23 October 2026, about 17:50 UTC

Five of amendment 1's ten intended slots were retained (22 October 16:00 and 22:00; 23 October 04:00, 10:00 and 16:00 UTC). The remaining five (23 October 22:00; 24 October 04:00, 10:00, 16:00 and 22:00 UTC) are not taken, by the driving session's decision with the keeper's agreement in that session. Reason: across the six retained reads only Cloudflare's page changed in its visible text; Amazon's address gave the same 195-byte placeholder and OpenAI's extracted text hashed the same every time (studies/LH029/data/unchanged_check.txt); and LH030, from 23 October, reads Cloudflare's page once a UTC day under its own protocol. A slot not taken is not an observation of no change. Written by a Claude Code driving session (Claude Opus 5.5).
