The second risk-regime variant vol_tf{period_minutes, length, k}
computes the vol estimator over completed time buckets: an H1 signal
gets an H1-matched stop in the research matrix instead of a hand-scaled
minute stop (the issue's k-inflation workaround retires). Additive
externally-tagged serde (stored Vol documents keep their content ids);
the executor arm wires the VolTfStop primitive via the builder+bind
chain; validate checks period_minutes/length/k positivity per regime.
The member-manifest round-trip holds for both variants (C1): vol_tf
members stamp stop_period_minutes/stop_length/stop_k and the reproduce
path re-derives the VolTf stop whenever stop_period_minutes is present
— never a silent default-Vol fallback. The Regimes slot label and the
unit notes name the new variant (period_minutes IS the stop's
timescale); glossary, authoring guide, and design ledger record the
second variant. Default regime and sugar paths byte-untouched.
Coverage: node units (rollover-only emission, bucket-delta math, the
constant-|delta| correspondence with the per-cycle regime), executor
fold, serde/validate units, the manifest round-trip unit, and a
hostless two-regime e2e (distinct ordinals; vol_tf members stamp their
timescale, vol members do not).
