I marked the owner line on every account card and still hesitated when the owner was a program rather than a person. Han let that hesitation stay on the table until evening five. The review sheet I took home is the first page I have been able to reread without a glossary open.
Naomi Cho came to Jinju for a research term and arrived at the library with a printout of an account she had been told to “just read.” The owner field was the system program. She had been treating it as the name of an exchange clerk. Evening one did not touch her printout. Han spent it on lamports, because Naomi’s notes had already dropped nine zeros once.
On evening two her printout finally reached the table, secret values already crossed out before she left her lodging. The group read address, owner, lamports, executable, data length. Naomi’s account was not executable and the data field was empty. That dull fact was the useful one: she stopped looking for a hidden program inside an ordinary SOL account.
Evening three was the hard night. A sample transaction was missing one signer, and Naomi argued that the other instructions could still settle. They could not. She said later that the argument, not the definition, is what she remembers. Evenings four and five put the instruction list and the owner rule next to each other. Evening six calculated two rent minimums from Han’s sheet and named the clusters without asking anyone to visit them.
She still writes to the desk when a token-account question appears, and she is told, politely, that the token shelf is a desk hour and not a seventh evening of the public series. She calls that boundary fussy, and she also calls it the reason she finished.
