Ingest FriendR public claim/stamp/disclosure contract into SDK

[KazanderDad]

Summary

Ingest the FriendR unique-human-confidence public contract into the canonical public SDK without adding a new runtime integration package.

Owning coordination

• Requesting issue: https://github.com/Cubid-Me/cubid-monorepo/issues/98
• Parent release goal: https://github.com/Cubid-Me/cubid-monorepo/issues/95
• Responding issue: this issue
• Requested outcome: public constants, types, classification helpers, generated references, and safe documentation for the existing Cubid contract.
• Expected handoff: reviewed SDK PR and exact released/merged contract evidence posted reciprocally to #98.
• Status: open; SDK implementation remains owned here.
• Blockers: none asserted by cubid-monorepo. SDK maintainers must validate current package surfaces before implementation.

Contract

• Actor self-claim remains Cubid-owned as cubid_actor_type.
• self_account_type_claim_v1 is a compatibility alias, not a mutable source of truth.
• cubid_kyc_presence_v1 is coarse, UserInfo/disclosure eligible, and not ID-token eligible by default.
• FriendR aggregate stamp type is friendr_unique_human_confidence_v1.
• Redacted summary claim is friendr_unique_human_confidence, scoped to cubid:stamps, UserInfo/disclosure-only.
• FriendR score effects appear only through existing consented cubid:score outputs.
• Redirect parameters and default ID tokens must not carry FriendR-derived evidence.
• Agent/organization evidence must not be represented as human personhood evidence.

Forbidden public modeling

Do not expose raw graphs, relationships, classifier/target identities, individual attestations, duplicate reports, contacts, XP, raw aggregate payloads, KYC provider details, or internal Cubid identifiers.

Acceptance

• Add public constants/types and safe classification helpers in the canonical packages.
• Document the scope/token/redirect boundaries.
• Regenerate references and pass focused/full SDK validation.
• Post the reviewed implementation handoff reciprocally to cubid-monorepo #98.

Reciprocal coordination from Cubid-Me/cubid-monorepo#98: this typed Project Task supersedes the live file-backed handoff. Cubid monorepo will remove the archived-folder file; SDK implementation remains owned here. Please post the reviewed implementation and compatibility evidence back to #98 when complete.
