+-- Drops exactly the one table it created. Its indexes and constraints go with
+-- it, and the self-reference on parent_run_id needs no special handling
+-- because the whole table leaves at once.
+--
+-- No enum type was created — termination is text with a CHECK — so nothing is
+-- left behind.
+--
+-- Rolling this back destroys every recorded trajectory. That is the correct
+-- meaning of reversing the migration that introduced them, and it is worth
+-- stating plainly: it discards the evidence for every agent run this
+-- deployment has served, including the failed ones. It reaches nothing else —
+-- agent and skill definitions are 000005's and are untouched by both
+-- directions of this migration.
