§ 01
The problem
A new hire asks where the travel policy lives. A support agent asks which plan includes exports. A dispatcher asks what was agreed with one customer in 2024.
Someone knows. It is usually the person who is busy. Ostler is the colleague who has read everything and always tells you where.

Why every answer has a number
Typical assistant
Customers can leave with 30 days’ notice and will not be billed for the remaining months.
Sounds right. Is it? You would have to go and check. Most people will not.
Ostler
Customers must give 60 days’ written notice.¹ Annual plans are still billed for the remaining months.²

Why every answer needs a footnote
An answer without a source is a guess with good manners. Here is how we decided that citations are the product, not a feature.

How we check that a source really says what we claim
A citation that points at the wrong page is worse than no citation. This is the checking step we run before an answer is shown.
