If the AI machinery making or inspecting a product also decides when to stop, we've given it control of the process as well as the work. Manufacture, inspection, and repair form the core loop in a deterministic pipeline, with any other required stages placed before, after, or between them. The pipeline supplies each stage with recorded inputs and follows its recorded outcome, including routing a repaired product back toward inspection. The assigned models can still make the product, record inspection observations, and correct defects; they don't set the acceptance rules or decide what happens next.

Before work begins, we record the criteria and inspection methods used to judge a product; together they form its acceptance basis.

Manufacturing works at scale because every part doesn't have to be identical; it has to satisfy its specification within limits set for the job. Those limits make it possible to use made-to-spec parts with confidence. Cognitive products need the same freedom: two reports can use different wording and both be acceptable, while an unsupported conclusion can put either one outside tolerance.

We start by naming a characteristic of the product which inspection can examine. A requirement states what that characteristic must satisfy, while tolerance defines how much variation is permitted. A finding outside that tolerance blocks release. The requirement and tolerance applied to one characteristic form an acceptance criterion; the complete set of criteria and inspection methods is the product's acceptance basis.

This isn't left as a general instruction such as “production quality.” Each characteristic reaches inspection with a stable identity, its requirement, whether it applies, the permitted variation, and the method used to assess it. A tighter tolerance can make the same finding block release, but the selected tolerances are recorded before the run and aren't changed by the inspecting model.

The product assignment describes what manufacture is expected to produce: the product's intended use, the source material it may rely on, the required characteristics, and the boundary within which the stage may work. Those requirements belong to the product, so changing the machinery or instructions does not quietly change the standard the result must meet.

The manufacturing method describes how the stage will attempt the work. It identifies the instructions, model or other machinery, tools and permissions, operating conditions, resource limits, known limitations, and the output the stage must return. A different method may be faster, cheaper, or more likely to produce an acceptable first revision; it still manufactures the product defined by the assignment.

Manufacture receives the applicable requirements so it knows what it is trying to make, but it does not decide whether its own result is acceptable or which failures would prevent release. When the stage finishes, the production record identifies the product revision it made and records what actually happened during that attempt. Other stages may then transform or validate the product before inspection; if one of them changes it, inspection receives the resulting revision rather than the original manufacturing output.

Manufacture has produced a product, but we still need to establish whether the product meets its acceptance basis. Inspection receives a specific product revision, together with the characteristics and requirements the product must satisfy and the source material needed to make those judgments. The inspecting model examines the product revision and records what it finds for each characteristic, including the supporting evidence and whether the requirement is satisfied, unsatisfied, or unresolved. Results from other stages, such as tests, calculations, or record validation, can also be supplied as supporting information.

Tolerance lets us specify which defects are acceptable for a particular product. A defect records where a characteristic has failed to meet its requirement; depending on the declared tolerance, the defect may be recorded without preventing release or may block release until the defect is corrected.

Manufacture, inspection, or repair may uncover a defect in the source material, such as missing evidence or conflicting information. The process records the defect and applies the declared tolerance to determine whether work can continue or must stop.

Repair receives the rejected product revision, the recorded defect, and the source material used to manufacture the product. Repair uses the source material to check the correction against the information the product was meant to rely on, rather than rewriting only the part inspection flagged. The inspection record also shows which requirements were satisfied, so repair can concentrate on the defect without losing work that was already sound. A record saying only “failed inspection” would force repair to rediscover the problem before making the correction.

Repair produces a new revision of the rejected product and records what changed. The rejected product revision and failed inspection remain unchanged. Other stages may process the repaired product before reinspection. If another stage changes the product, inspection receives the resulting product revision.

The pipeline doesn't ask a model what to do next. The pipeline reads the recorded outcome from the current stage and follows a route defined before the run. The declared route determines which product revision and records the next stage receives.
