{{Info|title=Forking across time β the full demo|1=[[Sandbox/Version demo]] showed versioning. [[Sandbox/ModelFork]] showed forking. This page shows '''both β multiple sync cycles between an upstream and its downstream fork''' β using the most important data model ever conceived: the 7 colours of the rainbow.}}<br />
<br />
== Once upon a time... ==<br />
<br />
A '''Development Entity''' owned the canonical Rainbow Colour Model. Seven simple colours. Life was peaceful.<br />
<br />
Then '''Unicorn Dev''' appeared. Unicorns '''love''' rainbows. They forked the model immediately.<br />
<br />
Then the Development Entity went '''absolutely unhinged'''. Types changed. Colours were deleted. Random fields appeared out of nowhere.<br />
<br />
Unicorn Dev had to keep up β without losing their sparkle.<br />
<br />
== The cast ==<br />

=== Dev's frozen history ===<br />
<br />
* [[Sandbox/RainbowFork/Dev/ColourModel/1.0.0|v1.0.0 "The Classic"]] β 7 colours, all strings, the world made sense<br />
* [[Sandbox/RainbowFork/Dev/ColourModel/2.0.0|v2.0.0 "Tech Disruption"]] β types changed, colours deleted, chaos begins<br />
<br />
=== Unicorn's frozen history ===<br />
<br />
* [[Sandbox/RainbowFork/Prod/Unicorn/ColourModel/1.0.0|v1.0.0 "Born from Rainbows"]] β fork point, identical to Dev v1.0.0<br />
* [[Sandbox/RainbowFork/Prod/Unicorn/ColourModel/2.0.0|v2.0.0 "Getting Fancy"]] β custom fields added<br />
* [[Sandbox/RainbowFork/Prod/Unicorn/ColourModel/3.0.0|v3.0.0 "Sync Wave 1"]] β first selective sync from Dev v2.0.0<br />
