+"""Repair Yahoo adj-close / event-date misalignment (see
+scripts/scan_adj_misalign.py).
+
+For a hit date D (adj spikes, close flat, price drops later) the repair is
+purely arithmetic and leaves cumulative returns unchanged:
+
+  r(t) = adj(t)/close(t);  k = r(D)/r(D-1)          # the bogus spike
+  f   = 1 - 1/k                                      # dist fraction Yahoo applied
+  d   = f * close(D-1)                               # implied per-share dist
+  E   = first t > D with close(t) < close(t-1) - 0.5*d   # true ex-div date
+  for t in [D, E):  adj(t) *= (1 - f)                # restore pre-event ratio
+
+For t before D and from E on the series is already consistent, so only the
+[D, E) window is patched. The patch is written as a 'history' correction
+(overrides/corrections/{SYM}.json, merged, with a note), so it survives
+re-downloads that rewrite the raw CSVs with the same Yahoo values.
