Reference Systems

Decades of UAP data are already classified under other systems. The reference systems make those classifications first-class data so historical and institutional records can be ingested without losing their original coding.

They are deliberately off the root barrel — the core import surface of origins is the OCS taxonomy. Reach them via subpaths:

import { HYNEK_SYSTEM, HYNEK_CATEGORIES } from '@disclosureos/origins/reference/hynek';
import { VALLEE_BEHAVIORS, VALLEE_INTERACTIONS } from '@disclosureos/origins/reference/vallee';
import { AARO_SYSTEM, AARO_CATEGORIES } from '@disclosureos/origins/reference/aaro';
import { GEIPAN_SYSTEM, GEIPAN_CATEGORIES } from '@disclosureos/origins/reference/geipan';
// or everything: '@disclosureos/origins/reference'

Hynek

J. Allen Hynek's close-encounter scale, extended with the proposed CE4–CE7 categories:

HYNEK_SYSTEM.RV;
// { category: 'RV', label: 'Radar-Visual',
//   description: 'Anomaly confirmed on radar and simultaneously by visual observation.' }

Vallée

Jacques Vallée's two-axis system: a behavior code (AN anomaly, FB flyby, MA maneuver, CE close encounter) crossed with an interaction level (1–5), plus the SVP credibility rating (source/site visit/possible-explanation digits).

import type { ValleeClassification, ValleeSVP } from '@disclosureos/origins/reference/vallee';

AARO

The Pentagon's All-domain Anomaly Resolution Office resolution categories — the vocabulary modern U.S. government reporting resolves cases into:

airborne_clutter · natural_atmospheric · usg_industry · foreign_adversary · other_scientific_discovery

GEIPAN

The French space agency's case-classification grades — the longest-running official civilian UAP investigation:

A (identified) · B (probably identified) · C (insufficient data) · D1/D2 (unidentified after rigorous analysis), with strangeness/consistency ratings.

Relationship to the OCS

Reference classifications and OCS claims answer different questions:

• Hynek/Vallée describe the phenomenology of the encounter (what kind of sighting it was) — not what caused it.
• AARO/GEIPAN record an institutional resolution status.
• The OCS organizes causal hypotheses with attributed confidence.

A record can carry all three: a Hynek RV coding from a 1960s catalog, a GEIPAN D1 status, and a modern OCS claim — none overwrites the others. Keep reference codings in your ingest mapping or the extensions bag, and express causal judgments as origin claims.
