CRIT-1: request_log prepends prefix on every call; per-byte loop in γ
sketch would emit 32 prefix-only lines. Fix: snprintf buffered emit.
CRIT-2: γ dump block missing null guard on destination_data[]; the
plan's env-var check is outside the current_slot != NULL guard. Fix:
nest the dump inside the existing slot-null guard.
IMP-1: "stale residue from prior decode" not eliminated as alternative
explanation for the 16x32 patch. Add memset-zero-before-QBUF experiment
to Phase 7 to discriminate.
IMP-2: γ-first defensible but on IMP-1 grounds, not the
three-signature argument (which is weaker than stated).
IMP-3/4 placement clarifications. MIN-1/2/3 cosmetic.
5 mechanical amendments locked for Phase 6. γ-first strategy stands.
