October 2025: Migration and test-data rename consistency fixed in fjordllc/bootcamp. Re-applied rename adjustments lost during a rebase; fixed capitalization in confirmation messages and emotion labeling in tests (e.g., 'negative' -> 'Negative', 'happy' -> 'positive'). Reverted an unnecessary rename in a past migration to restore original class/method names, avoiding unintended data modifications. Result: more reliable migrations, stable test expectations, and preserved application behavior.
