Finished intelligence from publicly available information, for watch floors, posts and teams forward.
A port-security mission at Varna watches the western Black Sea from its operations center, on Sentinel, with a patrol vessel offshore on TAK. At 05:35Z on 13 Oct 2026 a real public report relays the Bulgarian government's statement that overnight, drones struck two vessels off the coast, one sunk, rated HIGH. Inside the minute Sentinel publishes it to the common operating picture and, as a Cursor on Target event, to the patrol's TAK devices; Nemesis drafts three courses of action, and by 05:41Z the watch officer has sent the patrol to the search, each step logged. What follows arrives as confirmation: at 07:01Z the Prime Minister's update joins the thread, Bulgaria summons Russia's ambassador and asks NATO and EU partners for help with the investigation and for more air and maritime surveillance; at 09:51Z a report says eleven crew are missing; by 10:00Z seven updates and eight later reports have joined the story, each counted once. Illustrative mission, patrol, ratings and plan.

The first report leads the thread. Official statements and later reports join it as they land, so the watch follows one story.

Courses of action
When a report crosses a mission's tripwire, Nemesis drafts courses of action from the standing plan.
A HIGH report inside the western Black Sea watch area crossed the maritime tripwire. Three courses of action follow, drawn from the plan.
Send the plan's maritime advisory to flagged vessels and their agents in the corridor. Attach the report and its location. Ask for position reports every four hours.
Low. An advisory changes no transit plans and uses a channel already in the plan.
High. The advisory list and the channel are kept current in the plan.
Illustrative plan, tripwire and courses of action for a maritime watch, a different mission from the story above. The trigger is the real report of 13 Oct 2026, 05:35Z.
