docs(sleep): definitive clean results — Sonnet->Haiku 3/3 seeds 0->1.00

Browse Source 
Strong-optimizer/weak-target (Sonnet -> Haiku), fully isolated:
  brief-writer, advisor, thorough-analyst all 0.00 -> 1.00 on held-out.
thorough-analyst shows 2-night convergence (0.33 -> 1.00). Codex self-optimized
brief-writer also 0 -> 1.00.

Key finding answering the optimizer/target-split request: the OPTIMIZER MODEL is
decisive — weak Haiku-as-optimizer is flaky (0 or 1.0 across runs), strong
Sonnet-as-optimizer reliably hits 1.0 on every seed. Raw logs under docs/sleep/raw/.
