Estimate Assemble

Estimate — Assemble estimate.json

Assembler unit. The Estimate phase reads design.json, applies the layered pricing source (cached anchors), computes a coarse monthly magnitude, and writes inline within (Step 4). This unit records the artifact-level contract for the phase: it is the single creator of , and its postconditions (declared on the phase) are the phase’s completion gate. See § Step 4 for the estimate.json shape (monthly_magnitude_usd, pricing_source, assumptions, note) and the magnitude-only determinism caveat.
