Design the Production System and the Work

Turn workflow, data, model behavior, explicit rules, UI, persistence, controls, deployment constraints, and team ownership into one executable system design.

Coming weekly after Episode 1. Target runtime: 45 to 55 minutes.

Questions this episode answers

Design the whole system before local decisions drift apart.

These are the questions the episode keeps returning to across product, engineering, evaluation, and ownership.

System question

Does the architecture show the complete path from input to decision rather than only the model call?

Leadership question

Are frontend, backend, QA, and product working from the same finding and evidence contracts?

Production question

Have security, latency, cost, observability, and recovery changed the design before implementation spreads?

What you’ll see

What Episode 3 shows.

The walkthrough stays anchored to real artifacts and the decision each one supports.

01Complete system path

Input → perception → rules → assurance → scoring → review → output.

02Model boundary

Where probabilistic interpretation ends and deterministic application logic begins.

03Frontend/backend contract

Request, response, evidence, progress, error, score, and review-state structures.

04Persistence + audit trail

Runs, rules, findings, evidence, decisions, and versions that make a result traceable.

05Deployment boundary

Environment, secrets, retention, security, and operational constraints that affect architecture.

06Dependency graph

How PM, UX, FEE, BEE, Test/QA, and FDE work overlap instead of moving through a waterfall.

Concrete 77 Rules evidence

The contract matters more than which team drew the box.

77 Rules converts model interpretation into structured evidence, explicit findings, deterministic scoring, and review state. That makes the frontend/backend boundary inspectable instead of coupling the interface directly to free-form model output.
