Good day!

On emerge and other operations, I see the next sequence of actions:
1. Packages state is pulled (repositories, `/etc/portage/package.accept_keywords`, etc.). This is versions of the packages, the USE flags, the arch keywords, etc. 2. User demands are pulled (`@world`, `/etc/portage/package.use`, etc.). These demands are
required version of the packages, the USE flag demands, etc. 3. They are pushed to the SAT resolver. 4. The decision is made. (The new full tree, "diff" for the tree - it doesn't matter here.)
Questions:
1. Am I correct?

The directive you may have specified in ACCEPT_KEYWORDS in your /etc/portage/ make.conf, over-written by any package specific stable ARCH or testing ~ARCH entries you have added in your /etc/portage/package.accept_keywords will determine if a package version is selected to be emerged as stable or testing.

https://wiki.gentoo.org/wiki/ACCEPT_KEYWORDS

The default USE flags for any package are determined by your chosen profile (eselect profile list) and they are in turn overwritten by any optional USE flags you have set for all packages in /etc/portage/make.conf, or for individual packages in /etc/portage/package.use

https://wiki.gentoo.org/wiki/USE_flag https://wiki.gentoo.org/wiki//etc/portage/package.use

2. Are there some tools (or projects for such tools) to show:
2a. the result and the sources of the p.1
(e.g., "there
are `=mail-client/claws-mail-{3.21.0-r1,4.2.0-r3,4.3.0-r2,9999}` from `::gentoo`; the applied keyword `amd64` for `=mail-client/claws-mail-4.2.0-r3` came from `/etc/portage/package.accept_keywords:17`") and
2b. the result and the sources of the p.2
(e.g. "the user input is: `=mail-client/claws-mail-4.2.0-r3`;
the USE flag demand `mail-client/claws-mail[smime]` came from `/etc/portage/package.accept_keywords:2`")
Thanks!

Sincerely,
Alexander Kurakin.

There are various tools besides the output of 'emerge -pv <package>' which
will indicate the version you are about to install and the USE flags to be configured for it. As a minimum I use these:

app-portage/gentoolkit
app-portage/portage-utils

but there are more to choose from:
