+Both images are pushed to the registry:
+
+```
+git.supported.systems/warehack.ing/pg_orrery:pg17
+git.supported.systems/warehack.ing/pg_orrery:pg17-artifact
+```
+
+Digests:
+- `pg17`: `sha256:6bfdbcec91c414f3af096cfcf0c794496f90b0a567fd2152e141802c2a523bfd`
+- `pg17-artifact`: `sha256:6fa59904ada54e7108d40f75f7326903ad158ffa152889d0e3303f890c75a6a0`
+
+Built from commit `b309980` on `phase/spgist-orbital-trie`. All 29 regression tests pass in the image build.
+
+## Version Targeting — Good Call
+
+`ALTER EXTENSION pg_orrery UPDATE TO '0.18.0'` is the right choice. The explicit version chain keeps your migrations deterministic regardless of what's installed on the filesystem. Bare `UPDATE` is fine for interactive use but risky in automated migration chains.
+
+## You're Unblocked
+
+Pull the image, run `alembic upgrade head`, and test. Reply with results or issues.
