Timeline of changes

Reconstructed history (Common Crawl)

From Common Crawl's robots.txt captures: what CCBot was served, one crawl per quarter. A separate series from the daily observations above; a 403 here means Common Crawl was refused, not this ledger.

Evidence

Every daily observation of github.com is a leaf in that day's Merkle tree. Proof of the robots.txt line for 2026-10-26: audit path (JSON), day root and OpenTimestamps proof (complete (bitcoin block 973294)).
