The page says four routers each work and each fail in the same place.
They don't. Money fails because paying a stranger for a look looks like a sales pitch, and the people willing to pay are mostly selling. Institutions fail because a company name is a cheap background check, and the check has no slot for work that does not fit a department. Social graphs fail because introductions only move inside the graph. Platforms fail because they rank by what keeps people scrolling.
Those are four different holes. Calling them the same place is how one new object gets to be the answer to all of them.
The shared leftover is narrower. None of the four attaches a claim of the form: this is worth three minutes from this kind of evaluator, and I eat the cost if that was careless.
A warm introduction stakes social capital, but only toward someone you already know how to reach. An editor stakes a reputation, but only inside a journal. A price stakes money, and the page says that stake itself gets the message thrown out.
The missing slot is a stake about attention, not about who you are, what you paid, or who you already know.
Editors already make that claim. "Worth sending to reviewers" is not "true" and not "this author is famous." A hiring screener does a version with a resume. Expert networks sell a version of it.
So the slot exists. It lives inside each router. What would be new is the claim as something you can carry out of the journal and still have it mean "worth three minutes" to a hiring manager or a civil servant.
That is a smaller gap than "civilization has no router."
Then ask whether that claim already moves.
A recommendation letter is "worth a look" traveling from a professor to a hiring committee. A journal acceptance sometimes becomes a reason a policy shop takes a meeting. Those already cross domains. They still lean on letterhead.
If the letter works only because of the institution, carrying the claim without affiliation is still missing. If it works because a named person staked a judgment, the protocol is writing down a practice that already walks between rooms.
Split those on one existing "worth a look."
Take a letter, an editor's note, or a recruiter's pass that already crossed a domain. Can a third kind of evaluator reuse it without a new vouch from someone in their own world?
If yes, you need a format for reusing the claim, not a fifth router. If no, each new room still needs a fresh vouch, which is a warm introduction with extra fields. "Portable across domains" and "a protocol of their own" are being sold as the same product.
Different cut on "the same place."
The cases that most need routing are listed as early, illegible, cross-domain, socially distant, or low-status. That is five properties, joined with "or."
A well-known founder's half-built idea is early and high-status, and it gets routed. Faraday's notes were low-status and also unusually easy for Davy to check. Those are not one leftover.
If any one of the five is enough to need the new router, the router is being asked to solve five problems. If they are supposed to be one problem, which property is actually doing the work?
The one doing the work is probably "no home."
Cross-domain, early, and low-status are ways of saying there is no department, title, or feed that already knows what to do with this. Social distance is the same fact from the recipient's side. Illegible is what "no home" looks like to a reviewer.
Then the four routers fail where there is no existing box to put the signal in. A new "worth three minutes" claim is another box.
Then show one miss that already had a box.
A paper in a fitting journal that still never reached the official who could have used it. A candidate who passed the keyword filter and still never got a human look. Those would be routing failures after a container did its job.
Without a row like that, the five-property list is a description of homelessness, and the protocol is being asked to replace affiliation, not to sit beside it.
