# TrustCarry Protocol v0.3 — Research Claim 057

**Sealed record identifier.** `kaal:research-claim:persona-protocol-v0.3:057`

**Author-affirmed research claim.** A Persona record should be owned by its subject rather than its host, while append-only integrity should be reconciled with privacy through tombstones, encryption, restricted stores, and selective disclosure.

**Status.** Public research record. Not yet eligible for the published-source scholarly claim layer.

**Claim type.** design

**Holds when.**

- Persona Protocol v0.3 as proposed; not an adopted standard

**Protocol.** TrustCarry Protocol v0.3, historically titled and aliased as Persona Protocol v0.3.

**Supporting passage from Persona Protocol v0.3.**

> Two constraints follow. First, the record must be owned by its subject rather than by a host. On centralized platforms, "users earned their reputation but do NOT own reputation," and an account deletion destroys years of history with "near zero ability to reclaim the data," while scores remain "trapped in Silos" with no path to aggregation across platforms (Calcaterra, Kaal, and Sivalingam 2018, claims 3266953-009 and 3266953-010). Portability of the evidence commitment is the remedy. Second, append-only integrity does not justify indefinite public exposure. Tombstones, encryption, restricted stores, and selective disclosure preserve accountability without making sensitive content universally public.

**Source locator.** Line 224 of the sealed v0.3 source.
