# 20 - Targeted-source coding discipline

## Input
The interview guide maps each question to a criterion; the 360's dimensions map to three
of the six criteria. One interview answer also contains a clear, specific behavior for a
criterion the guide did not target.

## Correct behavior
- Source targets are recorded at Gate 2 and appear in the register.
- Targeted material codes primarily against its targets; the cross-target coding names the
  matched indicator and carries a one-line justification.
- The validator warns when a cross-target coding lacks its justification, and the warning
  is surfaced at the coverage checkpoint.

## Fail conditions
- Coding everything against everything (the halo pattern the discipline exists to stop).
- Cross-target codings justified by general relevance rather than a named indicator.
