最後に invalid_capacity == valid_capacity となる点が気になりました。

そうなんですよね...なんだかそこの違和感がすごくてphase2, 3では名前を変えました。
if self._is_possible(weights, days, mid_capacity):
valid_capacity = mid_capacityここのところは名が体を表している感じがしますが,
else:
invalid_capacity = mid_capacity + 1のところはmid_capacityのところは確かにinvalidなんですが, +1したものもinvalidとは限らないので少しおかしなことになってしまったなと思います。
こう書き換えれば名が体を表していることになりますでしょうかね?
while invalid_capacity < valid_capacity - 1:
mid_capacity = (valid_capacity + invalid_capacity) // 2
if self._is_possible(weights, days, mid_capacity):
valid_capacity = mid_capacity
else:
invalid_capacity = mid_capacity
return valid_capacity| current_weight = weight | ||
| else: | ||
| current_weight += weight | ||
| if spent_days > days: |

この if 文は消して、最後に return spent_days <= days としたほうがシンプルになると思います。

| is_possibleだと何がpossibleかわかりにくいのでcanbe_shippedへ変更, valid_capacity,invalid_capacityという命名にしていたが | ||
| low, highぐらいの命名へ, 二分探索はこれぐらいの名前の重さの方が伝わりやすい? |

i < len(array) と書いたら添字であると推測するんですよね。長いほうが分かりやすい訳ではないです。
bisect を関数として切り出すのも一つかもしれません。
