Shared usage-metering helpers for hosted-model features (FAQ generation, AI
|
|
ticket investigations). Whether a run counts against the org's message budget,
|
|
and how many credits remain, is the same question for every hosted-model
|
|
feature — kept here so each feature doesn't reimplement (or drift from) it.
|
|
|
|
OSS/self-hosted builds have no enterprise module: nothing is metered and
|
|
nothing is blocked (fail open).
