So that "stateless vs builder-adversary" and "lean vs stateless" isolate context
hygiene / review granularity WITHOUT the confound of the minimal prompts' reduced
testing pressure (which we found cuts ~25% of test methods). stateless = orig +
context hygiene; lean = orig + context hygiene + per-gate review. min stays the
pure minimal-prompt variant (isolates verbosity vs orig).

Same pattern + AI-as-adversary verification as builder-adversary-min, but the
role prompts add CONTEXT HYGIENE: /compact at every checkpoint (lossless — state
is on disk), read diffs not trees, spill bulk output to files, adversary loads
only {plan, STATUS, diff}. Loop agents non-resumed → fresh session per phase.
Targets cache-read (the dominant cost in a long loop) without changing what the
agents do or how they verify.
