+* preserve replay tool history and protect transcript publication ([6e2d24c](https://github.com/rynfar/meridian/commit/6e2d24ce47af8d595ca6eb854d029fadd896d199))
+* preserve safe appended context and deliver resume deltas atomically ([9d28328](https://github.com/rynfar/meridian/commit/9d2832885686b20f9a09326d2ff22afddf12a06c))
