The library

Questions about retirement, worked through historical examples. Every figure is computed in the open and names its source and its date. Where a number cannot be regenerated from what is published, it is not used.

Every amount and date is regenerated from the code that produced it by an automated test suite, and the build fails when a published figure and the code disagree. Each article carries its own calculation code and fixed input data, and says what was checked against them.

These checks establish agreement with the stated data and assumptions. They do not predict future results. The writing was reviewed by several AI readers, including one built by a different company than the one that drafted it. It has not been reviewed by a financial professional.

There will be more of these. Leave an address and I will write when the next one is published.
