POST 
/v4/graph/traverse

One endpoint, nineteen canonical queries (TG-QRY-3). Set query and give the matching input:

query	returns	input (bold = required)
A1	trust summary of a DID	did
A2	governing chain: corporation + ecosystems	did
A3	service endpoints	did
A4	linked VPs and contained VTCs	did
A5	credentials the DID holds	did, ecsSchema
A6	credentials the DID issued	did, ecsSchema
A7	participants of the DID by role	did, role
B1	issuer recovery for a credential	did, credentialId
B2	holder recovery for a credential	did, credentialId
C1	schemas owned by an ecosystem	ecosystemId
C2	participating DIDs grouped by role	ecosystemId, role, credentialSchemaId
C3	ecosystem governance summary	ecosystemId
D1	credentials based on a schema	credentialSchemaId
D2	participating DIDs of a schema	credentialSchemaId, role
E1	DIDs operated by a corporation	corporationId
E2	ecosystems controlled by a corporation	corporationId
E3	corporation governance summary	corporationId
F1	path between two entities	from, to (EntityRef)
G1	validator chain, root to leaf	participantId

role: HOLDER, ISSUER, VERIFIER, ISSUER_GRANTOR, VERIFIER_GRANTOR, ECOSYSTEM. ecsSchema: ServiceCredential, OrganizationCredential, PersonaCredential, UserAgentCredential. EntityRef: {type, id} with type one of Did, Corporation, Ecosystem, CredentialSchema, Participant, EcsCredential, Vtc, LinkedVerifiablePresentation, ServiceEndpoint.

Collection queries take limit (1..500, default 100) and cursor. Non-ACTIVE participants appear in traversal with their true state while referenced (TG-ACT-1), search never returns them.

Errors (TG-ERR-1 envelope): INVALID_INPUT, UNKNOWN_QUERY, UNKNOWN_ID, UNKNOWN_FILTER_FIELD, INVALID_CURSOR.
