Nobody keeps a record of what they assembled

You wire up a product from a dozen third-party services in a matter of days, then move on. The charges you can't attribute, the free tiers you breach without warning, the providers that reprice or ship breaking changes — none of it arrives as a crisis, it just accumulates. Interstitium is the record: every project, every service it depends on, what each one costs, and a weekly account of what changed.
