Cycle-close audit over the feature trio 75bfb93..d1b3a3d (#261#260#262). Architect verdict: clean — C1 (both stop variants and the
per-instrument cost round-trip through the manifest), C2 (rollover-only
emission), C18 (scalar cost wire form byte-identical; VolTf additive),
the four-scalar discipline (SessionFrankfurt bakes the timezone, no
string kind), and the match-arm lockstep across all four RiskRegime/
StopRule sites all hold; commit bodies match the diff. One low drift
item — the repeated 60·10^9 ns-per-minute literal in vol_tf_stop.rs —
fixed here as NS_PER_MINUTE rather than carried.
No regression scripts are configured (the architect is the sole gate);
full workspace suite green, clippy clean. Spec and plan working files
discarded per the audit lifecycle.
