Module quality_report 

Data Quality results read as a report: what is likely wrong, what depends on intent, and which columns have nothing to report.

Derived from DataQualityResults whenever it is drawn, so the engine, the session cache and the evidence drill-in keep working on observations; a finding only groups and ranks them.

Structs

Check

One check the run makes: what it looks for, how far it reached, what it found. The list is the answer to “checked for what?” when nothing turned up.

Coverage

How far the findings reach, beside them on every report: the checks that ran and what they read, the ones that did not and why, the rows behind the numbers, and what else bounds them. From what the run measured and saw; nothing here reads.

Finding

FindingsView

How the findings list is narrowed and ordered. Presentation only: it reads the report on screen, and nothing is measured again.

QualityReport

Enums

EvidenceRows

The rows behind a finding.

FindingOrder

The order findings are listed in within each severity.

Outcome

What one check found: nothing, something, nothing because there was nothing for it to look at, or nothing because this run could not look.

Severity

Constants

CHECKS_SHOWN

How many checks the collapsed list shows before “more”.

INTENT_CHECK

The check the declared intent makes, by the name the Checks list gives it.

INTENT_TITLES

The findings the declared intent makes.

THIN_SEGMENT_ROWS

A segment with fewer sampled rows than this is thin: only a large change in it clears the sampling noise, and a clean one says little.

Functions

advice

What a finding means for the data and what to do about it, a fragment a line. The reader knows what a null is; this says only what is particular.

build_report

check_choices

The checks that made a finding in report, each with how many, most important first.

checks

Every check, most important first.

column_choices

The columns a report can be narrowed to, each with how many findings name it, in the results’ column order.

columns_label

Column names joined until width, then “+N” for the rest.

coverage

describe

The finding’s numbers in a fragment, then the evidence that makes it concrete: the values, the spellings, the files.

percent

verdict

Headline counts, one line: the answer before the evidence.
