Documents why Fix F crashed at cluster scale (qpa: +0.898 → -0.976
between step 371 and step 500 in alpha-rl-qrgjr v7), the structural
Bellman self-consistency constraint atom_max >= WIN/(1-γ) that makes
the resolution trade-off fundamental, and the design alternatives
considered (non-uniform atoms, adaptive γ, two-headed Q). Recommends
shipping A+B+C+D+E only — the pre-Fix-F design implements the
structurally-correct atom span via WIN-tracking EWMA.
No code change in this commit — design document only. Empirical
result from v8 (alpha-rl-vxbpq, SHA 6d4a962e5) will determine whether
deeper atom-resolution work (Options 4.C or 4.E) is justified.
