# enumerate-dimension-values

## Purpose

Enumerate meaningful values or levels for a dimension or factor, including representative, experimental, boundary, pathological, or adversarial coverage.

## Input contract

```yaml
required: [dimensions, value_schema, mode]
optional: [ranges, spacing_strategy, domain_constraints, baseline_values]
constraints: [values are typed to the dimension; mode determines representative, experimental, boundary, pathological, or adversarial coverage]
```

## Procedure

1. Validate each dimension's type, range, units, and constraints.
2. Generate representative values and caller-requested boundary or extreme values.
3. For experimental mode, apply the supplied spacing strategy and preserve factor comparability.
4. Deduplicate and annotate rationale, provenance, and expected coverage.
5. Return the value set per dimension.

If the dimension values are ready for controlled combination, consider `construct-design-matrix` as the next tactic.
If the values define plausible perturbations around a conclusion, consider `assess-sensitivity` as the next tactic.

## Output contract

```yaml
produces: [dimension_value_sets, boundary_cases, spacing_annotations, coverage_rationale]
delta_fields: [findings, evidence_updates, decisions, uncertainties]
```

## Quality gates

- Preserve the source representative enumeration of 3-5 values per parameter when that mode is selected.
- Preserve experimental factor levels of 2-5 levels with an explicit spacing strategy.
- Boundary/extreme mode must include the caller-defined boundary, pathological, distribution-shift, rare-combination, or scale-extreme cases; do not invent a fixed case count.

## Parameterization

The caller must provide dimensions and types, valid ranges and units, enumeration mode, spacing strategy, baseline values, and domain constraints. If experimental mode is used, provide factor roles and the intended comparison design.

## Failure and counterexamples

Reject values outside declared domains, levels without units or semantics, or pathological cases presented as representative defaults.
