Platform.role.GetInspectRoleObservation

Call as

addon.Platform:GetInspectRoleObservation(unit)

Available directly through addon; no dependency is needed.

What it does

Observe a selected unit role on probe- and restricted-policy clients without issuing inspection requests. Known unit absence returns false. Prefer the callable modern inspection API, with legacy fallback only when that callable is absent; a selected failure never falls through. Require a positive finite integral specialization ID and consume only role return five from the exact one-argument GetSpecializationInfoByID call. Missing, failed, restricted or malformed required facts are unavailable; readable nonempty future role strings remain exact.

Arguments

Name	Type	What it does
`self`	`RMPlatform`	Rotation Master platform adapter (implicit with colon calls).
`unit`	`string`	Selected nonempty unit token; unchanged native argument.

Returns

1	`string \| boolean \| nil`	Known nonempty role string, false for known absent unit, or nil when unavailable.
2	`string \| nil`	Policy, capability or required-observation availability reason.

Editions

Built In helpers are registered on every edition. What differs is the game API they read; where one is missing the helper falls back or returns nil with a reason.

Not available on that edition (the reason is in the tooltip)
Only while Blizzard's deprecation fallbacks are on

Secret values (Retail and Forever)

On Retail and Forever the game hands addons secret values. This helper checks what it reads (addon.Platform:CanReadValue) and returns nil with a reason such as restricted-value instead of a secret it cannot compare. Treat nil as unavailable, not as false.

Example

local role = addon.Platform:GetInspectRoleObservation("target")
if role == nil then return nil end
return role == "HEALER"
