+/**
+ * v0.36.0.0 (T16) — calibration footer for `gbrain recall` morning pulse.
+ *
+ * Pure formatter. Given an active calibration profile, returns the
+ * conversational block to prepend or append to the recall output:
+ *
+ *   Calibration this quarter:
+ *     Brier 0.18 (was 0.22 90d ago — improving).
+ *     Right on early-stage tactics, late on macro by 18 months.
+ *     Over-confident on team execution; under-calibrated on regulatory risk.
+ *
+ *   Threads you opened and never came back to:
+ *     · AI search platform differentiation         (17 months silent)
+ *     · International expansion playbook           (12 months silent)
+ *
+ * Cold-brain branch: returns empty string when no profile or
+ * insufficient resolved takes. The caller decides whether to prepend
+ * the block; cold-brain absence is the cleanest non-event.
+ *
+ * v0.36.0.0 ship state: opt-in via `gbrain recall --show-calibration`
+ * to keep R3 regression posture (existing recall text shape unchanged
+ * for users who don't pass the flag). v0.37 defaults to on.
+ *
+ * Trend computation: v0.36.0.0 has only ONE profile snapshot (the most
+ * recent generation). Trend ("was X 90d ago — improving/declining")
+ * arrives when we accumulate generated_at history.
