`pytest --pdb` shows it happening in the bit that adds foreign keys:
```

-> cursor.execute(

1096 >> cursor.execute(
1097 ""UPDATE sqlite_master SET sql = ? WHERE name = ?"",
1098 (new_sql, table_name),
1099 )
1100 cursor.execute(""PRAGMA schema_version = %d"" % (schema_version + 1))
1101 -> cursor.execute(""PRAGMA writable_schema = 0"")
1102 # Have to VACUUM outside the transaction to ensure .foreign_keys property
1103 # can see the newly created foreign key.

Unfortunately it's an error that occurs on Python versions that have defensive mode turned on, and it doesn't look like there's a way to turn that mode off.
