The flag is not a prediction. The flag is a verification artefact. The desk still labels the brief with a source class and a competitive impact note. The flag is an additional label, not a replacement. A brief with a flag is read the same way as a brief without a flag — the analyst weighs the impact, the schedule and the source. The flag only tells the reader that a continuity event has been logged for the team.
The flag's value is in the cumulative read. A team that carries a stand-in across three cycles is in a different competitive posture than a team that runs a stable roster. The flag makes that visible without forcing the reader to compare three briefs side by side. The desk has always published the underlying facts; the flag is a presentation layer that makes the facts easier to compare.
The flag is also a discipline for the desk. A flag that is not verified is a flag that does not get published. The desk would rather publish a brief without a flag than publish a brief with an unverified flag. The standing flag inherits the desk's editorial standard: the strongest source class wins, and the brief is updated in place when a correction lands.
