Analysis settings

Scope: All {{ report.summary.row_count | count }} records
Missing-value markers: {% for marker in report.config.missing_values %}{{ marker | tojson }} {% else %}None{% endfor %}
Missing-value comparison: Whitespace trimmed; case-sensitive
Value normalization: Trim: {{ 'enabled' if report.config.normalization.trim else 'disabled' }}; collapse internal horizontal whitespace: {{ 'enabled' if report.config.normalization.collapse_internal_whitespace else 'disabled' }}. Raw preview values are preserved.
Duplicate comparison: Exact raw values across every column
Type inference: At least {{ (report.config.type_inference.minimum_confidence * 100) | round(1) }}% agreement across present values; configured strict date formats, dot-decimal numbers and true/false. Leading-zero identifiers remain text.
Date detection: Orders: {{ report.config.date_detection.orders | join(', ') }}; separators: {% for separator in report.config.date_detection.separators %}{{ separator | tojson }} {% endfor %}; ambiguous order: {{ report.config.date_detection.ambiguous_order or 'inferred only from unambiguous column evidence' }}
Enum candidates: Text columns with at most {{ report.config.enum_detection.maximum_distinct_values }} values when the dataset has at least {{ report.config.enum_detection.minimum_row_count | count }} rows
String lengths: Very short through {{ report.config.string_analysis.very_short_max_length }}; short through {{ report.config.string_analysis.short_max_length }}; medium through {{ report.config.string_analysis.medium_max_length }}; long through {{ report.config.string_analysis.long_max_length }}; otherwise very long. Up to {{ report.config.string_analysis.examples_per_length }} examples per length are retained when the maximum is {{ report.config.string_analysis.length_distribution_max_length }} or less.
Value representation: Complete through {{ report.config.value_examples.full_distribution_max_distinct }} distinct values; otherwise a reproducible sample of {{ report.config.value_examples.candidate_sample_size }}
Row numbering: Data records start at 1, excluding the header. Quoted multiline values count as one record.
Preview selection: First {{ report.config.preview_rows }} records; raw values preserved
JSON format: {{ report.format_version }} - revision {{ report.format_revision }} (experimental)
