ReadonlyapplicationReadonlybloksWhether this app process has read its Bloks prism configuration
(MobileProcessBloksPrism): the platform renders the neutral control
palette until it has.
ReadonlycontextThe request context as declared by the request builder.
ReadonlydeviceReadonlyendpointReadonlyfeaturesResolved features: edge-derived defaults merged with the declared ones.
ReadonlyidentityResolved identity (analytics requests resolve to anonymous).
ReadonlynavigationThe navigation's wire values at render time (NavigationWire).
ReadonlynetworkThis process's own network session (AndroidNetworkSession), absent until the app opens one.
ReadonlynowRender time in epoch milliseconds.
ReadonlypigeonPigeon session id of the header layer (stable for the app-start window).
ReadonlyprocessThe one process fact the whole device/network header set reads: whether this
app process began with a stored session (MobileProcessStart). A process
that began logged out (the 448 post-login process and the 451 launch) sends none of x-ig-device-timezone,
x-ig-device-languages, x-fb-network-properties, x-ig-last-connection-type
or the x-fb-session-* pair, while every process that began with a stored
session does; the headers are absent by state otherwise.
ReadonlyrequestReadonlysaltx-ig-salt-ids of the user flows running at render time (MobileUserFlows); absent when none is sent.
ReadonlysessionReadonlystackOptional ReadonlytasosThe build's x-fb-tasos-td-config mobile-config string at render time
(AndroidTasosTdConfigParam, read through the MobileConfig model when the
request renders): absent when the platform registered no declaration and
empty when the account has no stored value — a line of the header is present
only while it is non-empty.
Optional ReadonlythrottlingThe throttling detector's report at render time (AndroidThrottlingDetector):
absent until the process's first throttling answer and in a process whose
CDN sends none.
Readonlyuser
Read-only view a header value provider renders from: the classified request (the resolver's three inputs plus the stack), the raw request, and the device/session/application state at render time.
