Validation harness

Run a real historical bid through the engine and compare line-by-line. This is the proof point that the rulebook matches real-world pricing.

Historical bid payload

Paste a JSON payload with the bid's input (building, section, assemblies, objects) and actuals (final totals, and optionally per-line costs matched by line code or rule id). The engine runs the inputs and shows variance side by side.
