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

A cardboard box among identical boxes on a shop shelf
The same code on every shot.Everywhere something has already been printed: packaging in the shops, a poster in town, a sticker on the table.

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.

ruleset · version 2

{
  "rules": [
    {
      "when": "always",
      "then": { "type": "redirect", "url": "https://acme.com/warnung" }
    }
  ]
}

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.

Reprinting is the expensive part. Stop doing it.
