Core.health_forecast_conditions.readField

Call as

Core.health_forecast_conditions.readField(platform, object, key)

Record the dependency Core.health_forecast_conditions.readField, then call it by that name. A namespaced call does not pass self: use a colon call or pass the object yourself.

What it does

Reads object[key] for the health-forecast conditions without letting a restricted value, a non-table object or an index error escape.

Arguments

Name	Type	What it does
`platform`	`RMPlatform`	Platform whose CanReadValue decides readability.
`object`	`any`	Table to read, such as a damage history record.
`key`	`any`	Key to read.

Returns

1	`any`	The field's value (possibly nil), or nil on failure.
2	`string \| nil`	Reason on failure: restricted-value, invalid-health-forecast-data or health-forecast-data-error.

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.

It reads no game API directly.

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.

How the addon calls it

Core.health_forecast_conditions.GetConditionHealthForecast
```
current,why=readField(platform,provider,'current')
```
