Main idea

A flash card that is no longer a pillar goes in the trash. No archiving, no "superseded" marker, no trace of what has stopped mattering: the active deck maintains itself by removal.

This is not a failure. A card may have been right for a period, may have accompanied a transition or a discovery, may have been carried by a brilliant formulation more than by a durable truth. A personal pillar can be provisional without having been weak.

The rule runs head-on against the one that governs a note base, where nothing is deleted: a superseded note stays in place and points to the one that takes over, because it explains why you used to think that. Both rules are right in their own order. The base keeps the trace, that is its function; the deck carries what counts now, and keeping the old there would destroy precisely what it exists to tell you.

Why it matters

It lifts the inhibition that freezes these setups: you hesitate to remove because removing seems to disavow. Naming removal as a normal operation is what makes upkeep possible.

And it avoids a methodological mistake: importing the base's archiving doctrine into the deck, on the grounds that it is rigorous elsewhere.

Nuances and limits

Removal is irreversible, and a card goes out on an impression of the moment as much as on a fact. You sometimes lose a formulation you will not find again.

There is a recourse, though: what deserved to be kept can be kept in the note base, which throws nothing away. What disappears is the status, not necessarily the trace.

Open questions

• Should a removed card leave a note in the base, or does removal lose its sharpness the moment it produces an artifact?
