Myers diff algorithm (1986)

The published algorithm behind every diff tool you have used. The model summarises what the diff found; it does not do the finding, because arithmetic should not be guessed.

* About that monthly figure

It is an estimate at the scale one student reaches, not a quote. Before anything goes live, week three sets a ceiling:

A hard spending cap on every provider account, set before the project goes live.
A billing alert at half the cap, so nothing is a surprise.
Free tiers first: every project in this list is designed to sit inside one at student scale.
A kill switch: how to take the project offline in one step if the numbers move.
