The Residual Forge method

Quality is the gate. Savings are the result.

A cheaper model is not an optimization if it breaks the job. Residual Forge separates measurement, experimentation, and approval so efficiency claims survive scrutiny.

Three moves

Trace. Test. Decide.

Trace

Expose the unit economics of the full successful workflow—not merely one request.

Test

Change one meaningful lever at a time and retain failures alongside wins.

Decide

Recommend only candidates that clear quality, security, latency, and rollback requirements.

Candidate acceptance rule

Five gates between an experiment and a recommendation.

Mandatory requirements

Every schema, factual, safety, and task-completion requirement must pass.

Declared quality threshold

The acceptance rule is agreed before candidate results are reviewed.

Comparable cases

Baseline and candidate routes run on the same approved evaluation set where technically possible.

Honest economics

Cost is measured per successful run, with rates, volume assumptions, retries, and uncertainty disclosed.

Operational control

Limitations, data handling, monitoring needs, and a rollback path are part of the decision.

Typical levers

Only what the evidence makes relevant.

Built-in restraint

The diagnostic does not change production, train a foundation model, review unapproved confidential data, or certify security or compliance. It produces a decision package; implementation is a separate engagement.
