The pool needs the station's log, and it didn't answer.
No stand-in data is shown — this garden only grows from the real record.
Six degrees, on sealed ground only.
Pick two souls. The station walks the chain — and shows the receipt at every joint. Where no sealed trail exists, it says so honestly.
The nursery: sealed, but not yet rooted.
These plants are in the pool — every one carries at least one receipted string — but no sealed trail joins them to the mainland. The desk hunts one receipt each. The day one lands, that's a bridge.
An island is not a lesser plant — it is a plant whose paper trail hasn't been walked yet. The pool never invents a bridge to tidy the picture. Absence, shown honestly, is the desk's to-do list.
