The code is already up. The target is not.
A classic QR code is a dead address. If the campaign, the menu, the app store link or the end date changes, you reprint — or the code points at nothing. Here it always points at the same endpoint. What comes after that you change while the paper hangs on the wall.
- Where it hangs
- Everywhere something has already been printed: packaging in the shops, a poster in town, a sticker on the table.
- Why the paper stays
- Packaging is the most expensive medium you cannot call back. City posters are rarely taken down when the show is over. A 404 on an election poster is a statement of its own.

Ruleset version

The ruleset
An edit writes a new version. Rollback is a pointer.
Not a description of what the engine could do — this is the text a code carries. The first matching rule wins, and the last one always matches.

}The earlier version stays where it is, one click back. No data recovery project — and it takes effect in under a second.
Also
Same code, later truth.
- Job poster
- The position is filled → speculative application. The poster stays at the stop.
- Wine label
- The vintage is sold out → the shop of the current one.
- Recall
- In the shops already, and the warning page is live the same day.
