-An invalid `aggregate` arriving after mount is a rejected write, not a destroyed
-grid.
-
-The compiler's validation error was thrown synchronously out of the derivations
-layout effect, so it escaped the commit and React unmounted the grid subtree —
-measured as group rows 1 → 0 and a container of 0 bytes. Both doors into the
-derivations seam were fatal: a bad `aggregate` written through
-`setColumnAggregate`, and — the one every consumer can reach, with no pane, no
-grouping state and no knowledge of this feature — a bad `aggregate` on the
-`columns` prop on update.
-
-The update is now rejected whole: the row model keeps the derivations it already
-had, the grid stays interactive and keeps painting the values it was showing, and
-a later valid update still lands. The rejection is reported through `warnOnce`,
-keyed on the column, the fault location and the detail, so a second, different
-misconfiguration still warns instead of being swallowed by the first one's latch.
-
-Mount still throws, deliberately: there is no running grid to protect and a hard
-error surfaces a config bug at its cheapest moment.

+- An invalid `aggregate` arriving after mount is a rejected write, not a destroyed ([#550](https://github.com/cacheplane/pretable/pull/550))
+  grid.
+
+  The compiler's validation error was thrown synchronously out of the derivations
+  layout effect, so it escaped the commit and React unmounted the grid subtree —
+  measured as group rows 1 → 0 and a container of 0 bytes. Both doors into the
+  derivations seam were fatal: a bad `aggregate` written through
+  `setColumnAggregate`, and — the one every consumer can reach, with no pane, no
+  grouping state and no knowledge of this feature — a bad `aggregate` on the
+  `columns` prop on update.
+
+  The update is now rejected whole: the row model keeps the derivations it already
+  had, the grid stays interactive and keeps painting the values it was showing, and
+  a later valid update still lands. The rejection is reported through `warnOnce`,
+  keyed on the column, the fault location and the detail, so a second, different
+  misconfiguration still warns instead of being swallowed by the first one's latch.
+
+  Mount still throws, deliberately: there is no running grid to protect and a hard
