To insert urgent tasks without renumbering existing phases, use a decimal phase insertion. This adds a new work item as a decimal phase (e.g., 72.1) between two existing integer phases, preserving the original sequence.

Decimal phase management is a project planning technique for inserting mid-milestone work into an existing roadmap. It calculates a decimal number between two integer phases to maintain chronological sequence without rewriting the overall plan.

To insert a new phase between existing milestones, provide the after-phase number and task description. The workflow verifies the phase number, calculates the decimal position, and updates the roadmap state consistently.

Yes, decimal phase insertion is designed specifically for roadmaps using integer phase numbering. It validates your existing phase sequence and applies safe fallbacks to ensure minimal disruption to the overall project plan.

Limitations include relying on roadmaps that strictly use integer phase numbering. The mechanism requires argument parsing and phase verification gates to pass successfully to prevent sequence disruption during mid-milestone discoveries.
