From 1d247fbca1200baee1227ceab542d25939acc6b8 Mon Sep 17 00:00:00 2001 From: Joshua King Date: Tue, 15 Sep 2026 16:30:36 -0400 Subject: [PATCH 1/3] Deactivation preserves every referencing row (Feature 03, task 2) Tests for the no-data-loss deactivation contract over the existing set_child_active business function: a child with a definition, instance and completion event keeps all three rows byte-identical through deactivate and reactivate, is excluded from (and restored to) the active list, and stays in the full list. A structural guard proves the no-delete property: no module carries DELETE targeting children and ChildrenDao exposes no delete-shaped method.
