# Station 2: Assemble

> Building the unit from standard components: templates, skills, and protocols, with new fabrication as the exception.

The cheap station — and it stays cheap. On the pilot line, assembly of a working unit takes 49 seconds and \$0.37. The discipline of this station is not making assembly good; it is refusing to let assembly hide problems that belong upstream.

## Entry gate

Design's exit gate, intact: a red eval on record, a draft bill of materials, projected cost within target, and — for agents — the soul and contract documents.

## Standard work

Composition from standard parts: context files from templates, skills from the registry, tools from the toolroom, model bindings per the tiering table. One unit at a time — small batches until the process is proven — in an isolated workspace, by an assembly agent working from standardized work.

The rule that makes parts interchangeable at all: **never hand-fit, always fix the die.** A part that needs hand-fitting — a skill that only works with edits, a template that gets locally forked — is a defective *part*, and the defect report goes upstream to the parts process, not patched inline. Conventions are enforced during the build, not reviewed in afterward; the assembler follows the standard work or stops.

## Exit gate

One check, absolute: the unit assembles clean from parts plus BOM with **zero manual intervention**. Any manual touch is logged as a parts defect.

## Escalation

An assembler that stops on a confusing instruction is doing its job. Block before guess: ambiguity in the design goes back to Design; a part that will not compose without modification files a defect against the part and halts this unit until the die is fixed. Nothing is quietly patched to keep the line moving — quiet patches are how defective dies survive.

## Enforcement

No compilation-table row lands at this station; its gate is structural. The zero-manual-intervention rule is self-enforcing in kind: either the unit assembles from BOM alone or it does not, and the assembly log is the evidence. Every manual touch recorded there is an automatic defect report upstream.
