Platform.unit_identity.GetUnitIdentityObservation

Call as

addon.Platform:GetUnitIdentityObservation(unit, otherunit)

Available directly through addon; no dependency is needed.

What it does

Compare two exact unit tokens using UnitIsUnit after checking only the first token with UnitExists. A readable absent first unit returns false without comparing. Required missing, failed, restricted or malformed observations return nil with a reason. No second existence query, GUID lookup or inferred identity is added.

Arguments

Name	Type	What it does
`self`	`RMPlatform`	Rotation Master platform adapter (implicit with colon calls).
`unit`	`string`	First exact unit token, checked for existence before comparison.
`otherunit`	`string`	Second exact unit token, passed unchanged to UnitIsUnit.

Returns

1	`boolean \| nil`	Readable unit equality, false for a known absent first unit, or nil when required observations are unavailable.
2	`string \| nil`	Policy, token-validation or availability reason for a nil identity result.

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

Game API
`UnitExists`
`UnitIsUnit`

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 same = addon.Platform:GetUnitIdentityObservation("targettarget", "player")
if same == nil then return nil end
return same -- the target is attacking you
