Quantlib bootstraping fails on 5y swap
You're not the first to trip on this, and unfortunately the fact that the provided example is from a different era doesn't help.
Quite simply, you're not writing rates correctly. The 5-years swap ...

Quantlib-Python: use zero rates to get the originally bootstrapped curve
To retrieve the original curve, you need to use the same key tenors of the original curve and with the same interpolation. For instance, when you create the original curve as:

What is Dual Curve Bootstrapping? And how to do it, with an example?
A multi-curve means that you observe the discounting instruments (such as fed funds) and projection (libor, swap curve) and solve for all of them simultaneously; as opposed to bootstrapping separately ...

Bootstrap with QuantLib: Fair Swap or zero NPV
The problem is that you are not pricing the same thing, and for two reasons:
The vanilla instruments you are pricing should start on spot date and have a maturity with that start as reference

Estimating a Yield Curve in a country without Bond Stripping
You do not need zero rates to estimate a parametric
model of the yield curve, such as Nelson-Siegel.
Suppose for instance that you have a cross-section of
bond prices. Then:

No, you can't. You can never deduce the 3M/6M basis spread from 3 month instruments alone.

Why would a 15Y swap index=EUR3M and discount=OIS, show only a EUR3M-delta at 15Y
