Understanding reported signals and cadence.

Is every signal a confirmed strategic shift?: No. A reported event and an interpretation of its significance are different things. Check the original source and distinguish the facts from the analysis.
Will a Watchlist send a briefing every day?: Monitoring runs daily by default. If no relevant new findings are available, Polaris7 does not create or send an empty briefing.
