These are four new 18.75T-token, two-phase priors for d768 seed 0. Phase 0 is 15T tokens (80%); phase 1 starts at step 8448 and is 3.75T tokens (20%). The quality assumption is monotonic: q4 is best, followed by q3, q2, q1, and q0.
The recipes are intentionally prior-driven. Earlier experiments inform the cumulative epoch cap: every cXXqY source stays at or below four epochs across both phases. Use the CSV weights verbatim; its 400 weight columns are the complete phase-0 and phase-1 mixtures.
Family shares are ordered code_agent / science_math / knowledge / low_value / general. Quality shares are ordered q0 / q1 / q2 / q3 / q4.
