Definition
Locked role term. Expert in the role being filled. Runs the trainee through the week. Keeps their own section. Trusted to manage a known process. Supersedes [Area Trainer] per the same vocabulary-update lock as [Lead]. Shared disambiguation question with [Lead]: “when a gap shows up in the trainee, is this the trainee or the process?”
Explanation
The [Trainer] and the [Lead] split the same territory two different ways, and the split is deliberate. The [Trainer] is trusted, not audited, until the trainee graduates — that trust is what makes the training relationship work, because a trainee who suspects every rep is being scored trains differently than one who trusts the person teaching them. The [Lead] is the one who audits, but audits the process, not the [Trainer] themselves, which is exactly why the shared disambiguation question exists: when something goes wrong with a trainee, the question isn’t “did the Trainer fail” by default, it’s “is this the trainee or the process” — and only after that question gets answered does responsibility get assigned.
This is the second half of the vocabulary fix that also produced [Lead]: dropping “Area” from both role names once it started colliding in casual stage use. See [Lead] for the paired entry and [Training Ladder] for how [Trainer] sits as the second rung in the non-skippable progression that produces every role in the operation.
