feat: cross-domain relationship discovery — Capability-Schicht-Entwurf (CRA P1)
Stufe 1+2 der Ontologie-Entdeckung (User-Schaerfung #54): nicht Aehnlichkeit sondern STRUKTURELLE Beziehung. 93 Obligations -> BGE-M3 -> 101 cross-family Paare -> Opus klassifiziert in 8 Kategorien (genau eine je Paar). - scripts/obligation_discovery/cross_domain_pairs.py (Stufe 1, key-frei) - scripts/obligation_discovery/classify_relationships.py (Stufe 2, Opus) - obligations/cross_domain_relationships.json: 16 SHARED_CAPABILITY -> 8 Capabilities (mfa/session/transport-tls/code_signing/anomaly_detection), 23 SUPPORTED_BY (Hubs: vuln_identification_inventory<-SBOM-Familie 5x, vuln_remediation_patching 5x), 1 SAME_OBLIGATION (vuln_remediation_patching == provide_security_updates, MERGE-Kandidat), 42 OVERLAP_ONLY sauber verworfen. Erstentwurf der Capability-Schicht (Phase 4). Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>

Kategorien (genau EINE; bei Mehrdeutigkeit gilt diese Prioritaet):
|

1 SAME_OBLIGATION — dieselbe rechtliche Pflicht, nur pro Domaene anders formuliert -> MERGE-Kandidat.
|
||||
2 SUPPORTED_BY — A ist domaenenspezifische Auspraegung/Teilfall von B ODER A traegt zur Erfuellung von B bei. RICHTUNG angeben.
|
||||
3 SHARED_CAPABILITY — beide werden durch DIESELBE technische Faehigkeit erfuellt (z.B. MFA, TLS-Verschluesselung, digitale Signatur, Session-Management, Patch-Management, Logging-Pipeline). capability_name (snake_case) angeben.
|
||||
4 SHARED_PROCEDURE — beide ueber denselben operativen Prozess erfuellt, ohne gemeinsames technisches Artefakt.
|
||||
5 SHARED_EVIDENCE — beide erzeugen/nutzen denselben Nachweis (Audit-Log, SBOM, Release Notes). evidence_name angeben.
|
||||
6 SHARED_GUIDANCE — beide berufen sich auf denselben externen Standard (NIST/OWASP/ISO), sonst distinkt.
|
||||
7 OVERLAP_ONLY — nur oberflaechliche Wort-/Themenueberlappung, keine echte strukturelle Beziehung.
|
||||
8 UNRELATED — Falsch-Positiv der Embedding-Naehe.

{"results":[{"i":0,"relation":"SHARED_CAPABILITY","direction":"a->b|b->a|none","capability_name":"","evidence_name":"","reason":"max 18 Woerter"}]}
|
||||
Regeln: relation = genau eine der 8 Strings. direction nur bei SUPPORTED_BY, sonst "none".
|
||||
capability_name NUR bei SHARED_CAPABILITY (sonst ""), evidence_name NUR bei SHARED_EVIDENCE (sonst "").
|
||||
Sei streng: SHARED_GUIDANCE/OVERLAP_ONLY/UNRELATED grosszuegig nutzen; SAME_OBLIGATION nur bei echter Deckungsgleichheit.
