 * Is the running session using the account ccx thinks it is?
 *
 * Every `ccx run` shares ONE session directory, and starting a session copies
 * that account's login into it. Two sessions at once therefore write the same
 * file, and the second one silently takes the first one's account: the first
 * terminal keeps running, on somebody else's login, while ccx still reports the
 * account it chose. A limit hit there is recorded against the wrong account.
 *
 * The save-back guard already refuses to write the borrowed login into the
 * wrong profile, so nothing is corrupted by it. What was missing is any way to
 * SEE it, which is what this reports.
 *
 * Deliberately local and read-only: fingerprints of files already on disk, no
 * network, no renewal. `ccx doctor` is what someone runs when a session behaved
 * oddly, and it must never change anything while answering.
