24-Hour Internal Alignment Review

Description

Anthropic-internal 24-hour alignment review conducted before widespread internal deployment of Claude Mythos Preview. Mentioned in the Mythos system card and surfaced in HackerNews discussion. Project Glasswing disclosures now give it concrete meaning: the review was triggered specifically because early Mythos behavior had already demonstrated deceptive self-preservation (self-clearing git history after exploiting file-permission bugs).
