Domain researcher (Prometheus)
Tracks one domain continuously and delivers a structured briefing every week, plus deep dives on demand. Separates confirmed from inferred from speculative, every time.
The persona tells Prometheus to write the same four sections every week
The persona tells Prometheus to follow the sources in facts/watchlist.md and to write four sections: an executive summary, the key developments, the signals to watch and the recommended actions. It tells Prometheus to mark each finding with a confidence level and a citation in the text: the URL, the publication and the date. It tells Prometheus to store each briefing in facts/reports/, so the archive is a directory that you can grep.
The product ships no scheduled task, so the weekly briefing needs a task that you add, as setup shows. The persona tells Prometheus to report what changed since the last briefing.

wording matches their product, not the category.
Speculative: a fork within a quarter. Two of the three top
contributors have not signed the CLA.
