Struct WhyInputs 

pub struct WhyInputs<'a> {
    pub base: &'a str,
    pub key: &'a str,
    pub slices: Option<&'a SliceSet>,
    pub roster: Option<&'a BTreeMap<String, Vec<String>>>,
    pub entities: Option<Option<&'a DeclaredEntities>>,
    pub admin_answered: Option<usize>,
    pub storages: Option<&'a [StorageInfo]>,
    pub stored: Option<&'a StoredLookup>,
    pub wire: Option<&'a WireWatch>,
}

Everything the ladder judges, each ingredient honest about whether it was obtained. None always means not fetched — the rung it feeds answers NotAsked, never NotEstablished.

Fields

base: &'a str

key: &'a str

The key or selector as asked (params tolerated; stripped for algebra).

slices: Option<&'a SliceSet>

None = no registry was loaded (distinguishable from a loaded set that covers nothing — the crate::model::facts rule).

roster: Option<&'a BTreeMap<String, Vec<String>>>

None = the liveliness sweep was not made or failed.

entities: Option<Option<&'a DeclaredEntities>>

Outer None = the sweep was not made or failed; Some(None) = made, and no admin space answered (adminspace.enabled defaults off) — unknown, never zero (RFC 09 §5.1 O4).

admin_answered: Option<usize>

topology().answered — how many admin root docs replied. None = the sweep was not made or failed.

storages: Option<&'a [StorageInfo]>

None = the storage sweep was not made (or the admin space that would answer it did not).

stored: Option<&'a StoredLookup>

None = the bounded value GET did not run.

wire: Option<&'a WireWatch>

None = no listen window was requested (the default; O4 says so).
