Discovery cards — GM keeps these until revealed

Receiver strip and timing marks

19:41 — two short pulses, pause, one long pulse; repeated twice. Text: DO NOT OPEN BEFORE DAWN. Direction field copied from current mirror labels: A to survey field. No independent origin entered. Circle observation and interpretation in different colors. Try this: Keep the actual message separate from the unverified direction field.

Mirror mark comparison

Factory sheet: crescent scratch identifies mirror A; unmarked mirror is B. Present gantry: crescent mirror carries label B; unmarked mirror carries label A. Mark the mismatch without moving an arm. Try this: Compare physical identity with current labels before choosing a repair.

Simultaneous terrace observation

Hill lamp at 19:41: two shorts, pause, one long, repeated twice. Receiver strip advances during exactly those pulses. When Sora covers the hill lamp briefly, the receiver strip pauses too. Stars remain visible throughout. Try this: Tap the two patterns together and test whether their pauses track each other.

Hill-station dispatch record

19:41 maintenance transmission to parts receiver: DO NOT OPEN BEFORE DAWN. Subject: sealed replacement-parts box; binder cures overnight. Pulse sequence: two shorts, pause, one long, repeated twice. Sent by Sora. No astronomical alert issued. Try this: Compare exact time, sequence, and wording with the observatory strip.

Elva’s temporary repair board

18:55 visitor protected from loose glass; both arms held. Temporary labels moved while damaged ties replaced. A tag hung on unmarked mirror; B on crescent mirror. Check factory marks before survey. Service order: pin frame, correct label arms, reopen shutter. Try this: Reconstruct the emergency change and arrange the safe correction steps.
