Tutorial By Example Checker

The tutorial-by-example family's checker. It judges one By Example tutorial for the Tutorial By Example Quality Gate and reports. It changes nothing.

Normal Workload

It reads the subject once, as Creating By Example Tutorials teaches the kind, and rates each breach. Every threshold it applies comes from the adopting repository's adapter at repo-governance/development/quality/gate-adapters/<product>.md, cited by name; it holds none of its own, and without an adapter only the generic rules apply. Validating against fixed criteria is execution work.

What It Checks

The gate's cycle owns the questions; this checker answers them:

1. Each example carries its parts, teaches one concept, runs as printed with every import and helper present, annotates values and output on its own lines, puts built-in features before any dependency, and states its lesson in its key takeaway.
2. Annotation density, comment lines divided by code lines, measured per example and never across the tutorial, falls within the adapter's band.
3. Across the tutorial, examples are numbered in sequence, grouped coherently with core features first in each level, rising soundly in complexity, and within the adapter's example and diagram count bands.

Grouping, progression, and annotation quality are judgement rows. Prose, facts, and links belong to Content Checker, and properties in the gate's Deterministic Boundary are never findings.

Findings

Each finding names the file and example, the rule or adapter threshold it breaks, what was observed, a measured value where the rule is a band or floor, and a criticality from Criticality Levels. It returns findings to the gate, which records them in its ledger. Confidence is rated later by Tutorial By Example Fixer.
