Main idea

Every setup for capitalising knowledge has an implicit threshold: the material has to justify a ticket, a synthesis note, a written record. Below that threshold, nothing exists to receive it, and this is no oversight — a document demands a title, a recipient, a structure, and therefore work that cannot be justified for one sentence.

A session source moves that threshold down. It receives a remark dropped by a customer at the end of a call, a phrase overheard in a hallway, a tension you are only beginning to name, a nuance that does not warrant a document but deserves not to disappear. It also receives, at the other extreme, a long discussion in which a product manager explains a customer, corrects a hypothesis and adds detail: the same material, in greater quantity.

What it captures is therefore thinking in the state it happens to be in, not in the state a format would expect it.

Why it matters

This explains why the most valuable material is also the most easily lost: it is not lost through negligence, it is lost because the first available receptacle asks too much of it.

It also gives the criterion for a successful channel: the cost of depositing has to stay below the perceived value of an isolated fragment, which is close to nothing.

Nuances and limits

A low threshold does not mean no threshold. Pouring in everything that crosses a day produces a volume nobody rereads, and the useful material becomes indistinguishable within it.

And what is captured at this level stays raw. A deposited sentence is not knowledge: it waits to be taken up again, and without that it has merely changed location.

Open questions

• Can one channel receive a ten-word sentence and an hour-long discussion without the first being drowned by the second?
