Owner-ratified 2026-07-20: authored code is the pipeline's primary
output, so plan execution takes the judgment model — but keeps the
in-loop effort tier (high, not xhigh): the implementer is the
most-dispatched per-task role and volume x wall-clock still governs
its thinking budget. Applies to the frontmatter pin and the three
implement-loop dispatches (impl, impl-fix-spec, impl-fix-qual).
The compiler-driven-edit arm deliberately keeps its implementer
dispatch at sonnet/high: compiler-enumerated propagation is
mechanical, and the arm's policy header pins its own tier.
