Compared with the previous archived version (#1020 to #2941). Text is normalized before comparing: dates, counters and tokens show as ‹date›, ‹count›, ‹tok›, and noise-only edits are hidden. Rewindex shows changed passages with a few words of context, not a copy of the page. View the live page (opens in new tab).
Archive proof
Rewindex commits each page capture it captures to a daily checkpoint, chains it to the day before, and has the checkpoint timestamped by FreeTSA and DigiCert. That proves these records existed by then and have not been changed since, by anyone, Rewindex included.
LangChain added a trust-page notice stating that compromised LiteLLM and PHP components were absent from its environment or products, with no impact to services or customer data, plus a Certificate of Insurance (COI) - 2026 document. Text announcing the 2026 SOC 2 Type II report was removed; the diff does not establish that the report itself became unavailable.
