I suspect the term 'out of bounds' is a Traditional one, so I'm sure our Trads here will churp in. Your stellium in Scorpio in 5th makes a strong focus on 5th house matters. Mars conj sun suggests a strongly 'wilful' person and mars conj mercury can suggests forceful speech and arguementativeness. Thankfully Uranus is out of orb to sun, cos that would be explosive. Planets to close to sun (combust again Trad term) suggest it somehow weakens the strength of sun's rays --
Mercury and mars should be interpreted as if in 6th house cos they are within 5' orb of 6th house cusp going anti clockwise and are more effective in this house. Same with Jupiter conj 12th house cusp which weakens the expressions of Jupiter cos it's a 'cadent' house.
Houses: angular houses 1/7 4/10 the energies of planets placed here are obvious cos it's your 'shop window' visible for everyone to see. Next the succeedent houses 2/8 & 5/11 the energies in these houses are not in shop window the are in the shop, but stood behind the counter, ready to come out when needed. Lastly, cadent houses 6/12 & 3/9 these houses/planets are not in shop window or stood behind the counter, they are in the back storeroom and only come out when 'triggered' or an emergency and much harder to recognise and access...
The houses are like the backdrop of a stage, the setting if you like, the planets are like actors and the aspects are how the planets behave in that settings/stage....
This stellium is also involved in T Square configuration. Pluto is also a singleton ie: only planet in air element, which the chart lacks
T Pluto conj natal venus in 7th should bring intense romance prob with issues of control or manipulation. Have you felt this energy yet??
