## Shared terminology and scenario fragments


### S01. Single Person With One Local Account

Frozen source: [scenarios/ScenarioTests.md](../source/scenarios/ScenarioTests.md) lines 13–24; SHA-256 `0040dd866009ad1199e89f89267e3aab86894859f6ae6d07f393e4f0b8cdb6f5`.
Historical wording; this is not a current model definition.

```text
## S01. Single Person With One Local Account

Expected representation: one Natural Person, one Account in an application
Scope, one local Identifier, one Profile, and one Membership or access
relationship if the account belongs to a group.

Checks:

- The person is not identical to the account.
- The profile is not the credential.
- Authorization can project the account or subject into a Principal.

```

### Conflict: User

Frozen source: [terminology/TerminologyConflictMap.md](../source/terminology/TerminologyConflictMap.md) lines 6–28; SHA-256 `03cc685a840d47b36bf124aa8c1465216dfcb1c463f911dbe5e934b7fa81e3b6`.
Historical wording; this is not a current model definition.

```text
## Conflict: User

Problem: `user` can mean a person, account, login credential holder,
application profile, authorization subject, or product-facing actor.

Source evidence:

- SCIM User = provisionable Identity Record (`scim-rfc7643-rfc7644.md`)
- Keycloak/ZITADEL User = Account with credentials (`keycloak-organizations.md`,
  `zitadel-organizations-projects.md`)
- OpenFGA `user:` tuple prefix = Authorization Principal id (`openfga-modeling.md`)
- OIDC End-User = implied Natural Person, not modeled (`oidc-core-subject-identifiers.md`)

Canonical stance: do not use `user` as a root concept.

Current mapping rule:

- Provisioning record (SCIM/LDAP) → Identity Record
- Login-enabled product record → Account
- Public/local display → Profile
- Access evaluation → Principal or Authenticated Subject
- Human being → Natural Person

```

### Conflict: Identity

Frozen source: [terminology/TerminologyConflictMap.md](../source/terminology/TerminologyConflictMap.md) lines 29–43; SHA-256 `acf3297ff3ac425a535639c97c8e9368833d0e4e78225679263bcd5ab6ecbbed`.
Historical wording; this is not a current model definition.

```text
## Conflict: Identity

Problem: `identity` can mean selfhood, a directory record, an issuer-bound
subject, a set of claims, a DID, a credential, a profile, or an account.

Source evidence:

- Kratos Identity = traits + credentials (`ory-kratos-keto.md`)
- OIDC developers conflate `sub` with "identity" (`oidc-core-subject-identifiers.md`)
- DID is identifier, not identity record (`did-core.md`)
- VC credentialSubject = claims about subject (`vc-data-model-2.md`)

Canonical stance: avoid bare `identity`. Prefer Identity Record, Identifier,
Claim, Credential, Profile, Persona, or Synonymity Assertion.

```

### Conflict: Subject, Principal, Actor

Frozen source: [terminology/TerminologyConflictMap.md](../source/terminology/TerminologyConflictMap.md) lines 60–79; SHA-256 `5f7282450703c7ab38c6d6b044bf99731c274974dd8ece1785de74bdc1365feb`.
Historical wording; this is not a current model definition.

```text
## Conflict: Subject, Principal, Actor

Problem: protocols, authorization engines, and social models overload these terms.

Source evidence:

- OIDC Subject = issuer-scoped identifier (`oidc-core-subject-identifiers.md`)
- SAML Principal = authenticated subject in assertion (`saml-nameid-federation.md`)
- Cedar Principal = typed entity in authorization request (`cedar-principal-action-resource-context.md`)
- Zanzibar/OpenFGA Subject = opaque authz participant (`zanzibar-rebac.md`)
- ActivityPub Actor = server-hosted social entity (`activitypub-actors-followers.md`)
- FOAF Agent = actionable entity, includes Person (`foaf-agent-person-group-onlineaccount.md`)
- GDPR Data Subject = natural person (`gdpr-pseudonymization.md`)

Canonical stance:

- Actor = conceptual participant
- Authenticated Subject = issuer/protocol view
- Authorization Principal = decision-engine projection

```

### Conflict: Identifier, Credential, Claim

Frozen source: [terminology/TerminologyConflictMap.md](../source/terminology/TerminologyConflictMap.md) lines 150–162; SHA-256 `ff9f6502a126229aa65ea20817e698285a74df128aa35ea286cf24f87462216e`.
Historical wording; this is not a current model definition.

```text
## Conflict: Identifier, Credential, Claim

Problem: tokens and documents bundle all three.

Source evidence:

- OIDC ID Token contains sub (identifier) and claims (`oidc-core-subject-identifiers.md`)
- VC = signed claims with proof (`vc-data-model-2.md`)
- DID verification method = cryptographic credential (`did-core.md`)
- SAML AttributeStatement = claims; NameID = identifier (`saml-nameid-federation.md`)

Canonical stance: identifier refers; credential proves; claim states.

```

### Conflict: Synonymity, Linking, Matching, Merge

Frozen source: [terminology/TerminologyConflictMap.md](../source/terminology/TerminologyConflictMap.md) lines 163–177; SHA-256 `a714d30d2c1bedfcfe3020fa277c5a6226ec408eebd65efc33aadcba9b825ddf`.
Historical wording; this is not a current model definition.

```text
## Conflict: Synonymity, Linking, Matching, Merge

Problem: systems collapse probabilistic matches, verified links, and destructive
merges into one feature.

Source evidence:

- Probabilistic matching → weak assertion (`deterministic-vs-probabilistic-matching.md`)
- OIDC iss+sub binding → strong scoped assertion (`oidc`, `synonymity-assertions` notes)
- Schema.org sameAs = weak web equivalence (`schema-org` note)
- GDPR cross-linking raises identifiability risk (`gdpr-pseudonymization.md`)
- MDM golden record merge = downstream anti-pattern (`deterministic` note)

Canonical stance: synonymity is scoped, evidenced, revocable assertion.

```

### Conflict: Issuer

Frozen source: [terminology/TerminologyConflictMap.md](../source/terminology/TerminologyConflictMap.md) lines 191–203; SHA-256 `e7ca901947a8931fb1c427fa217f22bac361c15aa6c57da67580d799676980a7`.
Historical wording; this is not a current model definition.

```text
## Conflict: Issuer

Problem: issuer means OIDC OP, VC issuer, SAML IdP, or CSP.

Source evidence:

- OIDC iss claim defines subject namespace (`oidc-core-subject-identifiers.md`)
- VC issuer signs credential (`vc-data-model-2.md`)
- NIST CSP performs proofing (`nist-800-63-4.md`)

Canonical stance: Issuer = Scope authority + Trust Relationship; specify protocol
role when mapping.

```

### subject

Frozen source: [terminology/TerminologyInventory.md](../source/terminology/TerminologyInventory.md) lines 25–25; SHA-256 `904b2af8c84d271ad315098c387b00d51eef6463d3d4343c16469844f65f9cd5`.
