## Report Generation

## Report File

Default output: `DOCUMENT-ACCESSIBILITY-AUDIT.md` in the project root.

## Required Sections

Every audit report MUST include these sections:

1. **Audit Information** - date, auditor, profile, scope, counts
2. **Executive Summary** - totals, pass rate, most common issue, effort estimate
3. **Cross-Document Patterns** - recurring issues, systemic failures
4. **Findings by File** - per-document issues with rule ID, severity, location, WCAG, impact, remediation
5. **Findings by Rule (Cross-Reference)** - rule-level aggregation across files
6. **What Passed** - acknowledge clean documents and categories
7. **Remediation Priority** - ordered by impact (Immediate / Soon / When Possible)
8. **Accessibility Scorecard** - per-document scores and grades
9. **Metadata Dashboard** - document properties health
10. **Confidence Summary** - breakdown by confidence level

### Optional Sections (include when applicable)

- **Template Analysis** - when batch scanning detects shared templates
- **Comparison Report** - when re-scanning against a baseline
- **CI/CD Recommendations** - when no config files exist

## Severity Scoring Formula

The score and grade in a rendered report come from
`skills/a11y-core/scripts/merge-findings.mjs` (weights critical 10, serious 5,
moderate 2, minor 1; confidence high 1.0, medium 0.7, low 0.4; grades A 90+,
B 80+, C 70+, D 60+, F below). The formula is in `kb-web-severity-scoring`.
Map a document checker's levels onto the canonical severities first
(`kb-severity-mapping`) rather than scoring errors and warnings directly.

## Score Grades

Each score band, with its grade and meaning.

| Score | Grade | Meaning |
|-------|-------|---------|
| 90-100 | A | Excellent - few barriers found |
| 80-89 | B | Good - some barriers found |
| 70-79 | C | Needs Work - many barriers remain |
| 60-69 | D | Poor - significant barriers |
| 0-59 | F | Failing - unusable with AT |

## Organization Modes

Each mode, with description and best for.

| Mode | Description | Best For |
|------|-------------|----------|
| By file | Group all issues under each document | Small batches (< 10 files) |
| By issue type | Group all instances of each rule across documents | Seeing patterns |
| By severity | Critical first, then serious, moderate, minor | Prioritizing fixes |

## VPAT/ACR Compliance Export

### Conformance Levels

Each level, with its criteria.

| Level | Criteria |
|-------|----------|
| Supports | No findings for this WCAG criterion across any document |
| Partially Supports | Some documents pass, some fail |
| Does Not Support | All or most documents fail |
| Not Applicable | Criterion does not apply to scanned document types |

### Supported VPAT Editions

The current ITI template is VPAT 2.5Rev (24 April 2025), as of October 2026.

- **VPAT 2.5 (WCAG)** - maps to WCAG 2.0, 2.1 and 2.2 criteria
- **VPAT 2.5 (508)** - maps to Revised Section 508 standards (WCAG 2.0 AA)
- **VPAT 2.5 (EU)** - maps to EN 301 549; the template still points at V3.2.1 (WCAG 2.1 AA)
- **VPAT 2.5 (INT)** - International edition (all three combined)

4.1.1 Parsing is obsolete in WCAG 2.2 and is never reported as a 2.2 failure.
For the 4.1.1 rows that 2.0 and 2.1 based tables still carry, follow
`skills/kb-legal-compliance-mapping/SKILL.md`. Date every ACR and say which
edition and standard versions it covers.

## Remediation Tracking

When comparing against a baseline audit report:

| Status | Meaning |
|--------|---------|
| Fixed | Issue was in previous report but is now resolved |
| New | Issue was not in previous report but appears now |
| Persistent | Issue remains from previous report |
| Regressed | Issue was previously fixed but has returned |

### Progress Metrics

- Issue reduction percentage: `(fixed / previous_total) * 100`
- Score change: `current_score - previous_score`
- Documents improved: count of documents with higher scores
