Mockup of The Lobby, the reading case from the 4 Sep room: a threshold card with three names, Okafor's statement on paper with the ask above it, every tap answered by Okafor and never graded by the app, the receipt low on the page, the Bluebook item one tab away, and the record the case wrote.

01 · the threshold
Case 7 · the Vance gallery
11:40 p.m. One frame empty. Three people in the building.
OKAFOR
night guard
statement
PRIYA
cleaner

DALE
courier
one word
tap a name · the statement slides out of the folder
Names heavier than sentences. The eye lands on the three names, not on a block of text. The two gold pips are the cap the Learning Scientist asked for: two wrong lines and Okafor stops answering. Nothing on this card says what the case is testing.
02 · the statement, before any tap
Case 7 · Okafor
He says he never left the lobby. Tap the sentence that proves he did.
One line in his own words. The rest is scenery.
STATEMENT · OKAFOR, T.3rd · 23:58
I came on at ten. Lobby’s cold, so I watched the floors on the monitors, not on foot. Half past eleven, the freight elevator ran. Nobody uses it that late. I stayed put. By the time I’d got my hands warm on the second-floor radiator, it was quiet again.
The folderThe item
The ask sits above the paper, so the reader enters the statement already hunting. The statement is the document layer: serif, on paper, in Okafor's voice, with a sergeant's typed header. Nothing sits under the sentences being worked. The two tabs hang off the paper at low weight: the folder (his file, the shift sheet, the floor plan) and the item, which is the same case in the test's own shape, one tap away.
03 · the wrong tap
Case 7 · Okafor
He says he never left the lobby. Tap the sentence that proves he did.
STATEMENT · OKAFOR, T.3rd · 23:58
I came on at ten. Lobby’s cold, so I watched the floors on the monitors, not on foot. Half past eleven, the freight elevator ran. Nobody uses it that late. I stayed put. By the time I’d got my hands warm on the second-floor radiator, it was quiet again.
OKAFORElevator ran. Never said I was in it.
The folderThe item
Two things happen, in this order. The tapped line greys, which is the plain signal §7.3 requires and is all the app ever says. Then Okafor answers, in monospace because a person is speaking, and the answer is his defence rather than a verdict. One pip goes out. The record logs the sentence, not the miss: tapping the elevator means the reader inferred that someone moved, not that Okafor did.
03b · the second wrong tap
Case 7 · Okafor
He says he never left the lobby. Tap the sentence that proves he did.
STATEMENT · OKAFOR, T.3rd · 23:58
I came on at ten. Lobby’s cold, so I watched the floors on the monitors, not on foot. Half past eleven, the freight elevator ran. Nobody uses it that late. I stayed put. By the time I’d got my hands warm on the second-floor radiator, it was quiet again.
OKAFORHe’s done talking tonight.
Close the folder
the case stays open · the folder remembers both lines
This frame is the conflict, drawn. Two wrong and he stops, which the Learning Scientist wanted so that tapping every line is not a strategy. Spec §7.2 says closing has to be at least as easy as continuing, so the only action left is to close the folder, quietly, with no loss copy. The phone version resolves this with a rescue text from a character the student earned in an earlier case (Priya: “lol he literally told you where he was”). The folder version has no earned character yet. Card c32 on the review carries the decision: drop the cap, or bring the rescue with it.
04 · the right tap
Case 7 · Okafor
He says he never left the lobby. Tap the sentence that proves he did.
STATEMENT · OKAFOR, T.3rd · 23:58
I came on at ten. Lobby’s cold, so I watched the floors on the monitors, not on foot. Half past eleven, the freight elevator ran. Nobody uses it that late. I stayed put. By the time I’d got my hands warm on the second-floor radiator, it was quiet again.
Caught him on the radiator.Third one this week.
OKAFOR…Second floor. Yeah.
The folderThe item
Two tempos. The paper was still while the reader thought. The commit gets a beat of silence, then Okafor's concession, then the strike-through lands a beat after he speaks. The receipt is small type, low on the page, at the paper's own grain, worded in character. “Command of evidence. Cited.” was struck by Beckett as the test talking. The item tab lights up now: the four-card form is available after the tap, never under the sentence during it.
05 · the item tab · the same case in the test’s shape
Case 7 · the itemone tap away
The following is from a night guard’s statement. I came on at ten. Lobby’s cold, so I watched the floors on the monitors, not on foot. Half past eleven, the freight elevator ran. Nobody uses it that late. I stayed put. By the time I’d got my hands warm on the second-floor radiator, it was quiet again.
The guard claims he never left the lobby. Which quotation from the statement most directly undermines that claim?
A“Lobby’s cold, so I watched the floors on the monitors, not on foot.”
B“Half past eleven, the freight elevator ran.”
C“By the time I’d got my hands warm on the second-floor radiator, it was quiet again.”
D“Nobody uses it that late.”
the paper is test-shaped · vertical A–D · your tap is already marked
Why this tab exists. The principles keep the real item in Bluebook shape in view or one tap away, and the room deferred the four cards to after the arrest, which is further than that. This is the reconciliation: the same item, the test's own stem and register, reachable during the case, with the sentence the reader tapped already marked as C. It is a receipt in the test's shape rather than a second question. March has these.
06 · the record it wrote · never shown to the student
what the folder knows after case 7
operation · textual evidence
tapped, in order · elevator → radiator
elevator · inferred someone moved, not Okafor
tabs pulled · folder (shift sheet) before the tap
opened, untapped · no
next · Priya, cleared or charged · interleaved with a mastered operation
stays on the phone · picks Thursday · nobody reads it
One full case plus the record it wrote is what the Learning Scientist said was enough to diagnose. The operation is hidden from the student. The chosen wrong line is the diagnostic. Opened-but-untapped is its own state, kept apart from two wrong, and nothing texts anyone about it. Any parent-sharing setting shows on the corkboard like a pin, not here.
