01
An investigation begins with a question.
More documents do not necessarily make a situation clearer. Records about the same subject may have different dates and purposes, while relevant information may be distributed across several sources. Defining what needs to be understood establishes a basis for reading them.
HARBINGER investigates facts and evidence in documents and data. The work extends beyond finding a sentence to examining its claims, assumptions, related subjects, and time. The investigation question helps distinguish what has been covered from what remains outside the current review.

Comparison reveals what a difference means.
When a value changes, first establish whether the records describe the same thing. Different subjects, dates, units, or scopes can make a simple difference look like a change in the underlying situation. Separating observation from interpretation makes the next question more precise.
An investigation includes more than records that agree. Conflicting claims, records that challenge an explanation, and unknowns matter too. Together, they show which evidence supports the current analysis and what new information could change it.

The result becomes a starting point for further review.
HARBINGER can structure evidence, conflicts, assumptions, unknowns, and proposed next investigations. A reader can follow what has been examined and which questions remain, alongside the analytical conclusion.
When new material arrives, its differences and their effects on earlier analysis can be reviewed. Investigation therefore continues beyond a single summary, supporting a renewed understanding of the situation as conditions change.
