Each bundle is selected and prepared for the audience rather than published raw. Depending on what the week's investigations covered, it may include:
- deep dive research notes behind the week's investigations
- the important evidence and the primary sources it came from
- charts and supporting material used on air
- the principal facts and the assumptions they rest on
- the material uncertainties
- the questions that remain open
- developments that could change the picture
- links to the relevant shows
Not every episode produces a research note. Where a week's work does not warrant one, the bundle says so rather than padding itself out. There is no obligatory market preview, no chart for the sake of a chart and no reading list to fill space.
