"""Generic UPGRADE tier (Phase 1d DG2) — recipe-agnostic.

The orchestrator deployed the PREVIOUS published version once; this tier upgrades it IN PLACE
(abra app upgrade) to the target (VERSION env, else newest published) on the same live deployment,
then asserts it reconverges and still serves. Data-continuity is a recipe overlay (test_upgrade.py),
not the generic — the generic verifies the upgrade mechanism + still-serving."""
