source/ai/props 9/17 -> 10/17 from codex/props-full-admission-20260729,
found by branch_sweep.
Sweep hygiene note, learned here: the sweep's reported verdicts must be
re-verified before adoption. Its render/render row claimed
"exact 9 residual 0 unwritten 0" where re-running the gate on that same
blob gives exact 0 / unwritten 13 - far worse - so that row was a
measurement artifact and was not adopted. Only props reproduced.
Also measured and worth recording: an optimization-flag matrix on
circular_queue (/Ox, /O1, /Ob2, /Oi, /Og /Oi /Ot /Ob1, /Gf, /GF, /Oa,
/Ow, /Op, /QIfist, /Ot /Og) leaves /O2 as the clear best at 7/8 exact -
every alternative drops to 0-6/8. Flags are exonerated for that unit, so
its shared-zero-register residual is not flag-driven.
