description	Distinguish in-scope iteration from additional services and authorize the difference, so unbilled changes don't erode the fee. Reach for this when the design keeps changing.

Skill: Control scope creep

Unbilled scope changes erode the fee silently.

Step 1 — Define the baseline scope

What the fee covers, by phase (§3 #2).

Step 2 — Flag the creep

Identify out-of-scope options and changes.

Step 3 — Authorize additional services

Route the change to an additional-services authorization.

Step 4 — Protect the gate

Don't advance phases without approval (§3 #6).

Output

A scope baseline, flagged creep, an additional-services path, and a protected gate.
