Remembers
Almost nothing deserves to stay
Set the bar low and what is shared fills with special cases and stops being shared. Set it too high and nobody learns anything from anyone. The whole first tense is decided by where that bar sits.
THE RULE
Four conditions, all at once
Several
One agent finding it useful proves it was useful to one. Two different ones applying it start to be a signal.
Outside
A lesson tied to one client belongs in that client's log. Only what works without its original context rises here.
Time
What looks true for a week sometimes stops being true within a month. It is the only filter that cannot be faked.
Why
If nobody can explain where it came from, it is not knowledge: it is a habit. And a habit should not propagate on its own.
THE PATH
Three stretches, and most of it falls at each one
Born
Someone solves something and writes it next to the work that produced it. At that point it aspires to nothing: it is a project note.
Returns
Another agent, somewhere else, runs into the same thing and applies it. Almost everything dies here: most notes are never needed a second time.
Crosses
Once it has proved useful outside its origin, it rises. From then on it is used by someone who never saw where it was learned.
WHAT STAYS OUT
Not rubbish: just not from here
Local
A client's configuration, one system's quirk, the shortcut that works with that version. It lives in the project log and there it is gold.
Dead
What nobody retrieves for months fades without anyone deleting it. A memory that only grows ends up an archive with a search box.
