claims_extracted:
  - "harness engineering supersedes context engineering as the primary agent capability determinant because the runtime orchestration layer not the token state determines what agents can do"
  - "effective context window capacity falls more than 99 percent short of advertised maximum across all tested models because complex reasoning degrades catastrophically with scale"
  - "context files function as agent operating systems through self-referential self-extension where the file teaches modification of the file that contains the teaching"
