How to persuade AI to do some basic things in a very different ruleset?

In my Sim ruleset I have two problems with AI.
1. In Tribal government, Settlers are replaced by Tribe, a slightly more flexible unit that does have all properties of Settlers (and some additional ones). However, the AIs seem to refuse to build them and once I encounter them, they are left with the exact number of cities as was the number of initial Tribes that were given to them at the start of the game. Any idea how to make them build Tribes?
2. The game starts with no Palace. In order to progress to Despotism, the nation needs to build a Palace. But the AIs are not aware of this and they remain in Tribalism the whole time. I'm open to all suggestions about how to solve or go around this. Any way to give AIs an automatic palace?

I didn't dig the code, but maybe just having military capacities rules them out of civil production advisor. All I can pretend without core rewriting or great ruleset changes is replacing some warriors AIs build on tribes by a script.
About the palace, likely AI does not consider building->government dependencies. Give, like, some production bonus to AI Palace to make it understand it's useful.

Which freeciv version we're talking about? Unhardcoding "Settler" capabilities to (action enabler controlled) actions might have changed the criteria of what the advisor considers potential city building units.
btw. if you currently have a 3.0 ruleset, it should be relatively easy to test how things behave in 3.1. Just run 3.1 freeciv-ruleup for your 3.0 ruleset, and load resulting ruleset to 3.1.
For the Palace issue, I recommend to open a ticket to request that AI would consider (value) buildings that are government dependencies at least in the future versions.

Thanks.
The version is Fc21, so based on 3.0 so I don't know what changes affected what.

So, the requirement for effects that will work only for AIs is
"AI", ... , "Player"
where "..." is the AI difficulty level?
Also, I checked action enablers. Everything related to building cities requires the "Cities" flag, and Tribe has that.

So, what are those properties? Hard to comment what in them may make AI not to consider units for building cities without knowing what the units are.

Seems like yes. And a problem is that version compiled with --enable-debug has different list of AI levels, and "None" value is
not supported for it. I have requested "PlayerState" requirement in some ticket that should also tell if the player is AI controlled at all.

Hmm... Want for city founders is calculated in ai/default/aisettler.c:contemplate_new_city() and then put into city build consideration in ai/default/daidiomestic.c:domestic_advisor_choose_build(). Likely they both should understand which of the units is appliable, can't say what's the problem without running the ruleset in a debugger.

If you's like to try, this is the version of the ruleset for 2.6. The problem existed there, too.
