Struct Facts 

pub struct Facts {

    pub has_mail_binary: bool,
    pub has_docs_binary: bool,
    pub has_graph_binary: bool,
    pub mail_accounts: Option<usize>,
    pub docs_accounts: Option<usize>,
    pub slack_linked: Option<bool>,
    pub props: Option<Props>,
    pub provider_credential: bool,
    pub config_file: bool,
    pub local_probe: LocalProbe,
    pub scheduler_installed: bool,
    pub trigger_count: usize,
    pub charter: CharterState,
    pub declined: BTreeSet<String>,
}

Everything the impure half gathered, so plan can stay a function.

A struct rather than a pile of arguments because it is going to grow, and because a caller that has to remember the order of six booleans will eventually get one wrong in a way that reads as a working install.

Fields

has_mail_binary: bool

Which helper binaries are on PATH. A crates.io install gets each from its own cargo install, so “is it in the workspace” is the wrong question — presence on PATH is the one that matters.

has_docs_binary: bool

has_graph_binary: bool

mail_accounts: Option<usize>

Whether any account/credential store has something in it. None where the directory could not be read — see Status::Unknown.

docs_accounts: Option<usize>

slack_linked: Option<bool>

props: Option<Props>

What the default provider’s server said about itself, when it is local and answered.

provider_credential: bool

Whether the configured provider has a usable credential.

config_file: bool

Whether a global config file exists at all.

Config::load_global tolerates its absence and returns defaults, which is right — mecha must work before anybody has written one — but it meant a new install was never told the file exists or where it lives, and the first thing anyone needs to change lives in it.

local_probe: LocalProbe

What the loopback probe found — including whether it ran at all.

See LocalProbe. The point of the probe is to turn “anthropic has no usable credential” into “there is a server running right here, shall I write it down”, which is the difference between a remedy and a diagnosis.

scheduler_installed: bool

Whether a trigger scheduler is running or installed.

trigger_count: usize

charter: CharterState

What the owner’s charter is doing, read through the ordinary loader.

declined: BTreeSet<String>

Step ids the owner has said they do not want, from read_declined.

An unreadable store yields an empty set rather than a failure, and the direction is deliberate: showing a step somebody declined is a nuisance, hiding one they never declined is a silently incomplete install. This is the one place in this module where unknown resolves towards more noise, because here noise is the safe side. setup says out loud that the store could not be read — on stderr, and before the --json return, so the scriptable surface carries it too and stdout stays a parseable array.
