This reverts commit cdbc2d0. The bump was a judgment call without
evidence, and the planner design intent argues the other way: the plan
Iron Law is "EVERY STEP THAT CHANGES CODE INCLUDES THE CODE" and tasks
are sized so a subagent executes one "without judgement calls outside
its remit" (planner/SKILL.md) — the planner exists precisely to remove
design latitude from the implementer, which points at sonnet, not opus.
opus is only justified to the degree real plans leave slack (RED-step
invention, tree reconciliation, review repair), and that slack is
measurable, not felt. Restore sonnet/high; a future bump should be
grounded in the loop metrics (spec re-loop count, quality
changes_requested rate, end-verify BLOCKED rate) via postmortem, not a
gut call. The four fable gates (b591e75) are untouched.
