Template:TissueDB proposed swap notice

{{TissueDB proposed swap notice}} places a banner on a TissueDB material page stating that the material has been proposed as a substitute for another material but has not yet been validated by a pilot. It is part of the TissueDB project.

The notice exists to keep a proposal visibly distinct from a confirmed swap. A material swap only becomes official once a pilot has been run and a TissueDB Developer confirms it; until then the substitution is provisional, and this banner says so on the page itself rather than only in a tracking document.

Place the template at the top of the material page, above the Layout call.

{{TissueDB proposed swap notice|swap_for=[[TissueDB/Materials/Gelatin Mix|Gelatin]]}}

• Renders via {{Notice}} with the standard warning icon.
• Adds the page to Category:TissueDB proposed material swaps on transclusion. The category is applied by the template — the page does not need to add it.

• A proposed swap is not a swap. Do not record the substitution in the material swap registry, or state it as settled anywhere on the page, until a pilot has been run and a TissueDB Developer has confirmed it.
• Always set swap_for with a wiki link. The unset default reads "another material", which tells the reader nothing.
• Remove the notice when the swap is confirmed or rejected, and update the swap registry in the same edit. A stale provisional banner is worse than none, because readers stop trusting the banner.

For the current list, see Special:WhatLinksHere/Template:TissueDB proposed swap notice. Do not write the list here by hand. The list written on 19 July 2026 named three pages, and one of them was deleted on 27 July 2026, so the list was wrong and one of its links was broken.
