Standard
Cause waits for a second source. Crew identity stays off the board. Congestion is not an attack.
A dark AIS track is a missing signal. It is not a story about why the signal went dark.
- Eight items. No peeking at the reason until the board is in.
- 6 clears the seat. 7 is Practitioner. 8 is Strategist.
- A seal is cut only after a pass, and only upward. The chain does not forget a lower seal.
