Sun-requiring species must not sit in the computed shadow of a taller neighbour.
Well established · costly if ignored → warn
How it works
Photosynthesis. Compute shadow polygons from latitude, date, and mature height.
What to do about it
Move the taller neighbour to the polar edge, or move this plant out of its shadow.
The evidence
Evidence: settled without a trial - solar geometry.
Change history
Every change to this rule is one commit. This is what the project's version history records — the date and the reason — not a summary of it.
- corpus: another rule here says what to do about a computed shadow (remedy)
