Bound the assignment, not the answer
Every assignment supplies a role, cutoff, decision, source neighborhood, and handoff. Learners still own definitions, methods, uncertainty, and recommendations.
PEDAGOGICAL OPERATING STANDARD
Practice judgment before the stakes rise.
The Analyst is the simulation; Meridian Living Systems is the fictional employer that makes the work cohere. Each assignment changes the role and decision while the organization, source systems, definitions, and operating history remain consistent. The world is controlled enough to teach from, but the analytical choices remain real. It can support college and university courses, workforce programs, professional training, or structured self-study.
Make Python earn its place
SQL establishes governed evidence. Python handles work that benefits from programmatic analysis: visualization, inference, temporal validation, simulation, modeling, and error analysis.
Preserve useful mess
The estate contains declared source behavior—multiple clocks, sparse observations, fanout risk, delayed labels, technical replays, selection effects, and shifting populations. These are mechanisms, not random corruption.
Permit responsible refusal
A defensible result may be hold, monitor, shadow, collect better labels, or decline deployment. The simulation never requires false certainty to feel complete.
Separate mechanics from judgment
The current workbench captures successful runs with executed-code hashes, flags outputs that predate later worksheet edits, hashes exported files, and records explicitly bound non-empty handoff files. Instructors evaluate artifact quality, grain, time validity, analytical meaning, causal language, risk posture, and decisions.
Leave work another analyst can inspect
The submission contains code, queries, notes, evidence, outputs, run records, data revision, runtime versions, and content hashes. Reproducibility is part of the work product.
MECHANICALLY RECORDED
Successful browser runs with executed-code hashes, captured displayed outputs, stale-output status, runtime and data revisions, explicitly bound non-empty handoff files, and whether exported contents still match their saved hashes. These are not correctness certificates.
HUMAN-REVIEWED
Question framing, statistical reasoning, model choice, uncertainty, business consequences, causal restraint, communication, and whether the recommendation deserves action.
DELIVERY OPTIONS
Templates, small fixtures, query contracts, fold utilities, and explicit reconciliation prompts.
Data neighborhood, cutoff, deliverable contracts, and hints for mechanically detectable failure modes.
Executive request, source estate, workbench, and handoff requirements. The analytical route remains learner-owned.
These are selectable workbench settings. Supported mode supplies assignment-specific starters, Guided mode supplies a general investigation frame, and Independent mode opens with a nearly blank worksheet. Each mode keeps a separate local draft so a learner can make a deliberate fresh attempt without overwriting earlier work.
TEACHING AND ASSESSMENT
OPEN INSTRUCTOR DESK →The low-profile instructor desk holds sequencing guidance, the human-review boundary, a local submission viewer, and spoiler-separated assignment notes. None of those materials are required for self-directed use.
