## Description

Canonical AT completeness gate, research-anchored 7-category taxonomy (C1-C7) + 15-item mechanical checklist. Paradigm-neutral. Drives acceptance-designer reviewer verdict deterministically.

# AT Completeness Check, Canonical Taxonomy

Mechanical gate for acceptance-test completeness. Runs against any candidate AT set. Each unchecked item = potential gap. Verdict deterministic by count, not judgment.

**Provenance**: research-anchored 7-category taxonomy, paradigm-neutral. See `docs/research/at-edge-case-taxonomy-2026-05-19.md` for full literature review.

**Anchors** [1]-[14] reference research doc bibliography.

## Domain extensions

Project-specific AT-class specializations live as YAML overlays in `domain-extensions/` (sibling dir to this SKILL.md). The canonical 7-category taxonomy stays paradigm-neutral; domain overlays add `extra_checks` that the reviewer appends to the 15-item checklist for features opting in.

**When to add an extension**: project surfaces an AT-class that is a specialization of one or more canonical categories (typically C5 + C6) but not a new general category. Example: nWave IP/Privacy boundary = `public:false` mode flag (C5) + leak-in-output failure-contract (C6), lives in `domain-extensions/nwave-installer.yaml`, NOT in canonical taxonomy.

**Overlay schema** (`domain-extensions/<kebab-case-domain-id>.yaml`):

```yaml
name: <kebab-case-domain-id>
version: <semver>
applies_to: <project / package / feature-pattern>
extends_canonical: [C5, C6]      # which canonical categories this specializes
extra_checks:
  - id: <DomainID>a
    description: <what to verify>
    maps_to_canonical: C6
    mandatory: <bool>
```

**Opt-in per feature**, in `docs/feature/{id}/distill/at-completeness-extensions.yaml`:

```yaml
extensions: [nwave-installer]
```

Reviewer adds overlay's `extra_checks` to the canonical 15-item checklist for that feature only. Verdict thresholds scale with total item count.
