A building that promises reform and mostly delivers time.

means A prison, especially one run by a state or federal government for people convicted of serious crimes.

from Traces back to 'penitence' — Latin paenitentia, meaning repentance or regret for wrongdoing. The word entered English prison vocabulary through 'penitentiary houses,' institutions imagined in the 1700s as places of moral reform where inmates would reflect, repent, and emerge corrected — a hopeful theological label bolted onto what became, in practice, just the word for prison.
