Imani hesitated. Honesty was a family rule. "A little. Not because of him. Because the equation was lying."
Rhea almost smiled. "Equations don't lie. People do. Sometimes by accident. Sometimes because a broken problem teaches a lesson they think is useful."
"What lesson?"
"That some doors are meant to select," Rhea said. "Not to open."
Imani stared at the photograph of her grandmother. "That's not fair."
"No," Rhea said. "It isn't. Write down exactly what was on the board before you forget. Date. Time. Who was there. What he said. What you said. If this becomes a conversation with adults, memory will try to tidy itself."
Imani got her notebook. She wrote until her hand cramped. Rhea heated leftovers and made them both eat. Outside, a neighbor practiced trumpet poorly and with commitment. The ordinary world insisted on continuing.
At 8:42 p.m., Rhea's phone buzzed with an email from Halberd's parent portal.
Subject: Brief check-in regarding Imani's engagement in Algebra I
Rhea opened it. Imani watched her mother's face change by millimeters.
Mr. Ellery's message was polished. He praised Imani's "exceptional algebraic fluency." He noted that she had "publicly identified an intentional stressor problem designed to cultivate resilience." He suggested a "collaborative conversation about how we channel advanced readiness without disrupting classroom climate." He copied Dean Wexler. He used the word "fit" once, lightly, like a scarf draped over something sharp.
Rhea set the phone down. "They scheduled a fit conference," she said. "They just didn't use those words yet."
Imani's stomach dropped. "I only told the truth."
"I know," Rhea said. "Truth is not always the same currency as belonging. We are going to spend carefully."

The next morning the classroom looked the same and felt rearranged. Mr. Ellery erased yesterday's board before anyone arrived. The oval was gone. The broken equation was gone. In their place he had written a gentler warm-up: factoring that anyone diligent could finish. Imani sat in her seat with her backpack at her feet and tried to decide whether erasure was mercy or strategy.
"Good morning," Mr. Ellery said. His voice was even. "Yesterday we encountered a problem that was not solvable in the reals as written. That was intentional. Some of you may have found that unsettling. Mathematics sometimes is. Today we return to material that builds confidence."
Cole raised his hand. "So she was right?"
Mr. Ellery's pause was short enough to look like thoughtfulness. "Miss Quartey correctly identified that the expression, as presented, admitted no real solution. The pedagogical purpose was to observe approaches to impossibility. In the future, I will be clearer about when a problem is designed as a stressor."
Approaches to impossibility. Imani wrote the phrase in her notebook because it sounded like something adults said when they were building a hallway around a hole.
Rohan whispered, "He's covering."
