Explanation
- Explain the mask digits. The version nibble (13th hex digit) of each GUID, read in order, gives
8688748621558088434416. Exactly this sequence comes out ofnew Random(770).Next(9): the per-post millisecond seed of the mask generator. The other 30 hex digits of each GUID areGuid.NewGuid()output and carry no message. - Explain the count. Grouped in Before the scheduler: before the scheduled app (Jun 26 2012): sparse single tool runs / hand lists (o5o4o, jbucr, jkuyr), 2011 genuine-v4 lists; no long-lived count stream to fit
- Conclusion. Filler. The content is fully explained by the two RNGs.
