You insert urgent tasks by adding a decimal phase number, such as 72.1, between existing integer phases. This preserves the original roadmap sequence while accommodating mid-milestone discoveries without renumbering future phases.

Decimal phase management is a technique of labeling inserted tasks with decimal numbers within an integer-phase milestone roadmap. It allows mid-milestone updates to add urgent work between consecutive phases while keeping the original sequence intact.

Add a decimal phase by providing the target after-phase number and a description as arguments. The workflow validates the target phase exists, computes the correct decimal label, and updates the roadmap to slot the urgent work into the sequence.

Decimal phase insertion applies to roadmaps with integer phases. It validates the target phase and computes a new decimal label, but it is designed for integer-phase roadmaps rather than those already containing fractional phases.

The insertion workflow validates the target phase before processing. If the provided after-phase number does not exist in the roadmap, the validation fails and the decimal phase label is not computed or inserted.
