Threshold Watch
Every frontier lab publishes a safety framework: the capability thresholds that are supposed to trigger stronger safeguards. None of them publishes a version history. The thresholds differ between labs, change without notice, and changes are how commitments soften. This page does the versioning for them: each framework is fetched on a cadence, normalized, hashed, and archived. When the content changes, the new snapshot lands here, dated, with a diff where the source is text.
This is commitment one of the Control Stack Compact run in reverse: thresholds should be published in a common format and versioned like a changelog by the labs themselves. Until they are, the changelog lives here.
Subscribe to changes: RSS feed (a new item means a framework changed or entered tracking). Related: the Frontier Incident Timeline and the Compact Clauses for procurement.

Six labs publish a framework. None publishes a changelog a third party can verify. That last column is what this page exists to fill.

Read-only fetches of each lab's canonical public document. HTML sources are reduced to visible page text before hashing so cosmetic markup changes don't register as framework changes; PDFs are hashed byte-for-byte. A snapshot is kept only when the hash changes. Fetch failures are shown as-is rather than papered over. Source code ships in the major-labs repository (threshold-watch/fetch.py).
