THE TRUST VAULT ARCHITECTURE

Foundational Secure Repository Architecture for Human Digital Life in the Keyra Companion Ecosystem

Instrument: The Trust Vault Architecture

Function: Canonical architecture for the cryptographically secured repository of human digital life — enabling Companions, Digital Twins, Life Graphs, Family Trust Networks, Organization Graphs, KAAI Agents, and future digital economies to operate under human ownership and control

Version: 1.0 (Founding Architecture)

Status: Subordinate to the Human Sovereignty Charter; governed by the Companion Charter, Life Operating System, Human Digital Twin Architecture, Life Graph Architecture, Family Trust Network, Organization Graph Enterprise Companion Framework, and KAAI Standard

Core constraint: The Trust Vault belongs to the Sovereign Human. No platform, institution, or agent holds root authority over a Trust Vault by default.

Preamble

The digital age promised permanence and delivered ephemerality. Humans accumulated identity credentials across hundreds of accounts, memories across dozens of platforms, authorizations in opaque permission dialogs, relationships in proprietary graphs, assets in institutional silos, health records in incompatible portals, family archives in rented cloud buckets, and legacy intentions in scattered documents no executor can locate. Each system claims to store something for the human. None stores everything under human authority. None persists across vendor failure. None inherits without institutional gatekeeping. None answers a single question with integrity: Who owns this life, and who controls access to it?

Ownership without secure repository is theoretical. Sovereignty without encrypted persistence is rhetorical. Memory without governed retention is liability. Inheritance without vault architecture is chaos. The Human Sovereignty Charter establishes rights — ownership, control, portability, inspectability, deletion, revocation, inheritance. Rights require architecture that implements them when platforms dissolve, devices fail, humans die, and agents multiply.

This document defines the Trust Vault — the foundational secure repository architecture through which Keyra Companions, Human Digital Twins, Life Graphs, Family Trust Networks, Organization Graphs, KAAI-authorized agents, and future digital economies access, protect, and transmit human digital life under explicit constitutional governance.

The Trust Vault is not a product feature. It is not a folder. It is not a database owned by a vendor. It is the cryptographic substrate of human digital civilization — hierarchical in structure, federated in operation, local-first in execution, and global in interoperability potential.

It is designed for individuals today, families across generations, organizations under accountability, governments under law, and future generations who inherit digital life they did not create but deserve to receive intact.

Preamble — Historical Context

The history of digital storage is a history of misplaced trust. File systems stored bytes without semantics. Cloud storage stored objects without ownership. Password managers stored secrets without life context. Digital wallets stored value without memory. Knowledge bases stored information without authorization graphs. Each solved a fragment. None composed a life.

When artificial intelligence became persistent — companions that remember, agents that act, twins that represent — the fragment model collapsed. An agent cannot act responsibly without access to authorized secrets. A companion cannot serve without memory governed by retention policy. A family cannot inherit without vault partitions keyed to succession instruments. A court cannot subpoena what no standard repository holds. The Trust Vault closes the composition gap.

Preamble — Relationship to Founding Instruments

This Architecture is subordinate to the Human Sovereignty Charter. Where vault technical requirements appear to conflict with human sovereignty, human sovereignty prevails and vault implementations must be corrected. The Trust Vault integrates with the Life Graph Architecture (structure and references), Human Digital Twin Architecture (Twin persistence and key custody), Companion Charter (Companion-mediated vault access), Family Trust Network (Family Vault partitions), Organization Graph Enterprise Companion Framework (Enterprise Vault partitions), KAAI Standard (agent certificate storage, authorization signing keys), and Life Operating System (domain-scoped secure storage).

No single instrument owns the vault. The human owns the vault. The Life Graph indexes the vault. The Companion mediates human intent to vault operations. KAAI agents receive derived access through authorization chains rooted in vault-held keys. Together they form the Human Sovereignty Operating System for durable digital life.

Preamble — Normative Language

Throughout this document:

• MUST, MUST NOT, REQUIRED, and SHALL denote absolute requirements for Trust Vault conformance
• SHOULD and RECOMMENDED denote strong guidance with documented exceptions permitted only under human or institutional policy with audit
• MAY denotes optional capability
• Prohibited actions are void regardless of technical success; vault runtimes MUST reject them

Conformance is measured at three layers: constitutional (subordination to human authority), technical (encryption, key management, partition semantics), and operational (access audit, inheritance execution, incident response).

Preamble — Architectural Placement

The Trust Vault sits beneath human sovereignty and above application silos:

┌──────────────────────────────────────────────┐
│     Human Sovereignty Charter               │
├──────────────────────────────────────────────┤
│     Life Graph · Digital Twin · Companion   │

└──────────────────────────────────────────────┘

Applications are replaceable. Vault contents and keys are not — they belong to the human and persist across replacements.

Preamble — Scope of Support

The Trust Vault Architecture supports:

The Trust Vault serves:

• Individuals — personal vault root under sole human authority
• Families — federated family vault structures with governed sharing
• Organizations — institutional vault partitions subordinate to human members
• Governments — lawful access channels without root authority usurpation
• Future Generations — inheritance instruments, legacy vaults, succession execution

PART I — Definition

Section 1.01 — What Is a Trust Vault?

A Trust Vault is a cryptographically secured, hierarchically partitioned, human-rooted repository architecture — comprising Identity, Memory, Authorization, Relationship, Asset, Health, Family, Organization, Legacy, Companion, and Agent vault domains — through which a Sovereign Human stores, controls, inspects, exports, deletes, revokes, and inherits the artifacts of digital life under explicit constitutional governance.

The Trust Vault:

• Stores secrets and artifacts — credentials, documents, media, certificates, keys, configurations — encrypted at rest and in transit
• References structure externally — Life Graph holds metadata and edges; vault holds values and blobs
• Enforces authorization — every read, write, delete, export, and delegate requires validated grant chain
• Supports hierarchy — Personal, Family, Organization, Community, Legacy, National, and Global trust structures compose without merging sovereignty
• Enables inheritance — succession instruments, beneficiary edges, staged release, executor grants
• Audits access — immutable access logs with authorization references
• Persists across platforms — standard export packs; vendor-independent key custody model
• Operates local-first — primary replica on trusted device; federation for authorized sync

The Trust Vault is the secure persistence layer of the Human Sovereignty Operating System.

Section 1.01a — Trust Vault as Constitutional Implementation

The Human Sovereignty Charter declares rights. The Life Graph Architecture declares structure. The Trust Vault Architecture declares persistence — the material condition without which rights and structure evaporate when servers shut down, accounts suspend, or corporations restructure. A Sovereign Human whose Life Graph exists only on a vendor-hosted database does not possess sovereignty in any operational sense. A Sovereign Human whose keys are escrowed by default does not possess control in any cryptographic sense.

The Trust Vault therefore occupies a position analogous to land title registries in physical civilization — not glamorous, but foundational. Without title, property disputes become violence. Without vault, digital life disputes become platform support tickets that humans lose.

Section 1.01b — Actors Served by the Trust Vault

Each actor's relationship to the vault is defined, bounded, auditable, and revocable — except the human root, whose sovereignty is inalienable.

Section 1.02 — What Is Not a Trust Vault?

A Trust Vault is not:

• A cloud storage account — vendor-owned bucket with terms-of-service license masquerading as ownership
• A password manager — credential silo without memory, relationship, health, or inheritance semantics
• A digital wallet — value container without life-graph context or multi-domain composition
• A knowledge base — unstructured information store without authorization graph or sovereignty guarantees
• A file backup — byte replication without governance, retention policy, or access audit
• A platform profile — identity fragment owned by application operator
• A institutional record system — hospital or employer EHR/HRIS that holds copies but not human root authority
• A compulsory national database — centralized identity store without individual revocation and portability

If vault access cannot be revoked by the human root, it violates the Human Sovereignty Charter. If secrets appear in Life Graph plaintext, it violates the Life Graph Architecture. If inheritance executes without human-authorized instrument, it is not governed succession.

Section 1.03 — Distinctions Among Storage Systems

File Storage

File storage — local disks, network shares, object stores — persists named byte sequences without semantic ontology, authorization graph, retention governance, or inheritance workflow. Files do not know they are passports, memories, or medical directives. Access control is coarse — filesystem ACLs, bucket policies — not grant chains rooted in human sovereignty.

The Trust Vault may store file blobs as Memory or Document artifacts — but vault semantics transcend filesystem metaphors. A passport in the vault is an Identity artifact with expiration, renewal workflow, and inheritance rules — not merely passport.pdf.

Cloud Storage

Cloud storage — iCloud, Google Drive, Dropbox, S3 — offers convenience replication under vendor terms. The vendor typically claims license to operate, scan, and retain content. Export is adversarial. Account closure may forfeit access. Shared folders conflate visibility with ownership. Multi-generational inheritance is unsupported.

The Trust Vault may federate encrypted replicas to cloud custodians — but custodians hold ciphertext without root keys. The human holds keys. Custodianship is fiduciary, not proprietorship, per the Human Sovereignty Charter.

Password Managers

Password managers — 1Password, Bitwarden, LastPass — secure credentials with master password models. They excel at secrets but lack life context: no Memory governance, no Relationship vault, no Health partition, no Family inheritance, no Agent certificate lifecycle, no Companion configuration persistence. They are credential subsets, not life repositories.

The Trust Vault contains an Identity Vault that subsumes password manager function — with export interoperability to standalone password managers where humans prefer dual custody.

Digital Wallets

Digital wallets — Apple Wallet, crypto wallets, payment apps — store payment credentials, tickets, keys, and tokens. They optimize transaction velocity, not life continuity. They do not govern family memory, medical directives, or agent authorization chains. Asset vault integrations references wallet contents without conflating financial velocity with sovereign repository.

Knowledge Bases

Knowledge bases — Notion, Obsidian, enterprise wikis — store notes and documents with search and linking. They lack cryptographic sovereignty guarantees, standardized authorization graphs, KAAI audit integrations, and inheritance execution. Knowledge without vault governance is institutional or personal convenience — not constitutional persistence.

The Trust Vault indexes knowledge artifacts in Memory and Organization vaults with Life Graph edges — structured recall without plaintext secret leakage.

Trust Vaults (Generic industries Usage)

industries usage of "trust vault" often denotes institutional key escrow — HSM-backed secret storage for enterprises or certificate authorities. These vaults serve organizations, not sovereign humans. They rarely compose with family inheritance, companion memory, or personal health governance.

The Trust Vault Architecture defined here is human-rooted — institutional vaults are partitions subordinate to member sovereignty, not replacements for it.

Section 1.03a — Illustrative Scenario

Consider a sovereign professional: she holds passport and licenses in Identity Vault; career certificates and memberships linked; device trust keys for phone and laptop. Memory Vault stores photos, journals, conversation archives with retention policies — personal memories private, family events family_core federated to Family Memory Vault. Authorization Vault holds delegations to her Companion, KAAI scheduling agent, and attorney with quarterly review. Relationship Vault models family, colleagues, clients with trust scores. Asset Vault references property deed, vehicle title, investment accounts via encrypted refs. Health Vault stores immunization records, prescriptions, advance directive. Family Vault shares holiday archives with siblings under joint ownership rules. Organization Vault holds employment contracts and research notes — revoked on departure. Legacy Vault contains ethical will, video messages for children, Companion succession naming adult daughter as grant recipient.

When she travels, Companion requests passport ref — Authorization Engine validates trip context grant. When she is incapacitated, Emergency Vault releases medical directive to authorized spouse — audit notifies her when she recovers. When she dies, Inheritance Instrument executes — daughter receives Legacy Vault staged release; Organization Vault employment partition auto-revokes; Companion enters succession mode per Legacy instructions.

No platform owns the composite. She does.

Section 1.04 — Why Ownership Requires a Trust Vault

Ownership without repository is abstraction. The Human Sovereignty Charter declares absolute ownership of identity, memory, permissions, relationships, Digital Twin, and Life Graph. Implementation requires:

Without Trust Vault architecture, ownership rights remain declaratory — honored in charters, violated in practice.

Section 1.04a — Failure Scenarios Without Trust Vault

Scenario A — Platform dissolution: A photo service shuts down. Without vault export, decades of family memory vanish. With Trust Vault, encrypted replicas exist on human devices and designated custodians; memory refs in Life Graph resolve to surviving blobs.

Scenario B — Account suspension: A human is deplatformed without trial. Without vault sovereignty, identity credentials and authorization chains are inaccessible. With Trust Vault, local replica and portable keys preserve access independent of platform judgment.

Scenario C — Death without succession: A parent dies. Children possess no passwords. Platforms refuse access citing terms of service. Without Legacy Vault, ethical wills and medical history are lost. With governed inheritance, executor grants activate per instrument; staged releases reach intended beneficiaries.

Scenario D — Agent compromise: A shopping agent credential leaks. Without Authorization Vault, attacker gains standing API access. With KAAI certificate revocation rooted in vault, propagation invalidates agent access within SLA; audit reconstructs harm window.

Scenario E — Cross-border migration: A refugee flees jurisdiction. Cloud accounts geo-locked. Without portable vault, identity proof is stranded. With Trust Vault Export Pack on hardware key, credentials travel with the human.

Section 1.04b — Comparative Analysis: Pre-Vault vs Trust Vault

Section 1.04c — Implementation Roadmap for Humans

Typical individual timeline: 30–90 days for meaningful vault population; lifelong for legacy refinement.

Section 1.05 — Ecosystem integrations

The Trust Vault integrates with:

Section 1.06 — Temporal Horizon

The architecture is designed for three time horizons:

• Today — functional for individual vaults, family sharing, basic inheritance
• Tomorrow — multi-vault federation, agent proliferation, cross-border custody
• Future generations — century-scale legacy vaults, quantum-resistant migration, global trust infrastructure

Architectural decisions that optimize present convenience at the expense of generational sovereignty or cryptographic agility are rejected by this instrument.

Section 1.07 — Document Map

PART II — Sovereignty Principles

Section 2.01 — Ownership

The Sovereign Human owns the Trust Vault absolutely. Ownership includes all partitions, keys, artifacts, metadata, audit logs, and export packs. Ownership is inalienable — it may not be transferred to platforms, models, or agents. Custodianship of encrypted replicas confers no ownership interest.

Implementations MUST represent vault ownership in Identity Graph as Human → owns → TrustVaultRoot. No edge may assign Platform → owns → TrustVaultRoot without explicit human-initiated migration where human retains root.

Section 2.02 — Control

Control means the human determines who accesses what, when, under which conditions, and for how long. Control requires:

• Granular partition-level policies
• Time-bounded grants with automatic expiration
• Revocation propagation within defined SLA (RECOMMENDED: < 60 seconds for companion and agent grants)
• Human override of any automated access decision
• No silent elevation — scope expansion requires explicit human confirmation

Companions and agents mediate; they do not control. Control remains human-rooted.

Section 2.03 — Portability

The Sovereign Human MUST be able to export the complete vault — or selected partitions — in a standard Trust Vault Export Pack (TVEP) format without vendor gatekeeping. TVEP includes:

• Encrypted artifact bundles
• Life Graph structural export (or cross-reference manifest)
• Authorization graph snapshot
• Inheritance instrument copies
• Audit log excerpt
• Key material under human passphrase or hardware key — never vendor escrow by default

Portability MUST complete without network dependency where local replica exists. Cloud-only vaults without local export capability are non-conformant.

Section 2.04 — Inspectability

The human MUST inspect:

• All partitions and artifact metadata (titles, types, dates — not necessarily decrypted content in single view)
• All active grants and delegations
• All access logs pertaining to their vault
• All inheritance instruments and beneficiary designations
• All companion and agent vault permissions

Inspectability extends to authorized delegates — executors, guardians, compliance officers — within scope of their grants. Inspectability does not permit bulk surveillance of other humans' vaults.

Section 2.05 — Transparency

Vault operations MUST be transparent to the human:

• Access attempts — success and failure — logged
• Companion vault requests display purpose and scope before execution where latency permits
• Agent vault access cites Authorization Certificate chain
• Federation sync reports peer, partition, timestamp
• Inheritance preflight simulations available to living grantors

Opacity in vault access — hidden reads, undisclosed copies — is prohibited.

Section 2.06 — Deletion

The human MUST delete vault artifacts and partitions subject to:

• Shared memory policies declared in advance (Family Constitution may require consensus for joint partitions)
• Legal hold obligations human explicitly acknowledges
• Inheritance instruments that designate retention for beneficiaries

Deletion MUST propagate to authorized replicas within SLA. Implementations SHOULD support cryptographic erasure — key destruction rendering ciphertext unrecoverable. Deletion attestations MAY be stored in audit log for compliance.

Section 2.07 — Revocation

Every grant into the vault MUST be revocable by the human root or authorized delegate per scope. Revocation categories:

Revocation MUST NOT require vendor approval.

Section 2.08 — Inheritance

Inheritance is governed succession — not account transfer. The human MUST maintain Inheritance Instruments in Legacy Vault specifying beneficiaries, conditions, staged release, executor grants, and Companion succession. Inheritance execution MUST require:

• Valid cryptographic instrument
• Identity verification of beneficiaries per policy
• Audit trail
• Human institutional oversight where law requires

Default inheritance — platform-defined next-of-kin guessing — is prohibited.

Section 2.09 — Human Authority

Human authority is supreme within the vault stack. No agent, companion, family member, organization, or government holds standing root authority. Emergency and lawful access operate through exception channels with enhanced audit — not silent root keys.

Implementations MUST reject vault operations that cannot trace authorization to human root or valid inheritance instrument within bounded delegation depth.

Section 2.11 — Sovereignty Principle Enforcement

Enforcement mechanisms:

Violations MUST surface as errors — not silent degradation to platform defaults.

Section 2.12 — Tension Resolution

Principles occasionally tension:

• Transparency vs privacy — family member sees grant existence but not vault contents without read grant
• Deletion vs shared memory — joint policy pre-declared; anonymization option
• Portability vs DRM — licensed content exports with license refs; DRM objects flagged non-portable per issuer law
• Emergency vs control — emergency grants time-bounded; post-event human review mandatory

Resolution always favors human root authority after emergency expiry.

Section 2.10 — Principle Interaction Matrix

PART III — Vault Architecture

Section 3.01 — Hierarchical Trust Structures

The Trust Vault composes hierarchical trust structures — nested partitions with independent keys and policies, federated without sovereignty merge:

Global Trust Infrastructure (federation protocols)
└── National Trust Structures (lawful access overlays)
    └── Community Trust Structures (optional associations)
        └── Organization Trust Structures (enterprise partitions)
            └── Family Trust Structures (multi-generational federation)
                └── Personal Trust Vault (sovereign human root)
                    └── Legacy Vault (succession-designated)

Higher levels coordinate; they do not own lower levels. A family vault does not subsume individual vaults. An organization vault does not subsume personal identity.

Section 3.02 — Personal Trust Vault

The Personal Trust Vault is the root repository for a Sovereign Human. All other personal partitions — Identity, Memory, Authorization, Relationship, Asset, Health, Companion, Agent — nest within or federate from this root.

Properties:

• Single human root key (Keyra Key hierarchy)
• Default deny all external access
• Local-first primary replica
• Federation endpoints for family and organization sharing

Every human in the Ecosystem SHOULD possess a Personal Trust Vault — including minors under guardian custody of keys.

Section 3.03 — Family Trust Structures

Family Trust Structures federate Personal Trust Vaults per Family Trust Network instruments. Family Vault partitions — shared memory, joint documents, emergency chains — use:

• Threshold or consensus access for joint ownership
• Individual sovereignty preserved for non-shared partitions
• Inheritance edges crossing family boundaries with explicit beneficiary consent

Family structures are voluntary. Humans MAY participate in zero, one, or multiple family networks.

Section 3.04 — Organization Trust Structures

Organization Trust Structures provide Enterprise Vault partitions for institutional artifacts — policies, contracts, research, compliance, audit — linked to Organization Graph membership. Rules:

• Employment lifecycle triggers partition access review
• Personal vault never merged with enterprise vault
• Institutional keys subordinate to human member sovereignty for personal credentials

Section 3.05 — Community Vault

The Community Vault implements Community Trust Structures — neighborhoods, faith communities, cooperatives — MAY establish shared vault partitions for opt-in resources: emergency supplies coordination, shared calendars, cooperative assets. Community vaults lack authority over personal roots.

Section 3.06 — Legacy Vault

The Legacy Vault implements Legacy Trust Structures and designates post-mortem or incapacity succession. Legacy Vault operates as partition with:

• Pre-authorized executor grants inactive until trigger event
• Staged beneficiary release
• Companion and agent succession instructions

Legacy structures cross hierarchical boundaries — a Legacy Vault may release to family beneficiaries and revoke organization access simultaneously.

Section 3.07 — National Vault

The National Vault implements National Trust Structures and lawful government access without root key escrow. Models:

• Warrant channel — decrypted access per legal instrument, logged, notified to human where law permits
• Attestation federation — government verifies identity without bulk data collection
• Sector compliance — health, finance overlays per jurisdiction

National structures MUST NOT mandate single government master key to all citizen vaults. Sovereignty Charter prevails.

Section 3.08 — Global Trust Infrastructure

Global Trust Infrastructure — federation protocols, cross-border export standards, KAAI registry shards, trust attestation without data merge — enables interoperability at civilization scale. Global layer carries proofs and permissions, not centralized human secrets.

Section 3.09 — Vault Root Key Hierarchy

Keyra Root (hardware-backed human key)
├── Personal Partition Keys (derived)
├── Family Federation Keys (pairwise exchanged)
├── Organization Role Keys (employment-scoped)
├── Agent Delegation Keys (time-bounded)
└── Emergency Recovery Keys (Shamir optional)

Derivation MUST use approved KDF with domain separation per partition type.

Section 3.10 — Partition Taxonomy

Section 3.11 — Vault Lifecycle States

Section 3.12 — Custodian Model

Custodians — cloud providers, institutional hosts — operate under fiduciary constraints:

• Store ciphertext replicas only
• Never possess root keys by default
• Respond to lawful orders through warrant channel — not discretionary disclosure
• Maintain availability SLAs — 99.9% RECOMMENDED for paid custodian tier
• Participate in disaster recovery without accessing plaintext

Custodian contract terms MUST be subordinate to Human Sovereignty Charter. Custodian bankruptcy triggers automatic migration window — humans export without vendor cooperation prerequisite.

Section 3.13 — Vault Provisioning Ceremony

Recommended provisioning steps:

Provisioning SHOULD be memorable — humans understand they are establishing digital sovereignty, not creating another account.

PART IV — Identity Vault

Section 4.01 — Purpose

The Identity Vault stores credentials, attestations, and trust anchors that prove who the human is, what they are authorized to hold, and which devices act on their behalf. Identity artifacts enable Companions, agents, and institutions to authenticate without platform-specific silos.

Section 4.02 — Credential Classes

Biometric raw samples SHOULD NOT be stored in Identity Vault by default — only references to secure enclave templates where required.

Section 4.03 — Credential Lifecycle

Each credential artifact MUST maintain:

• issued_at, expires_at where applicable
• issuer Organization Graph reference
• renewal_workflow optional automation
• revocation_status
• Encrypted blob or structured field storage
• Life Graph IdentityCredential node cross-reference

Companion SHOULD surface expiration warnings per human policy — 90/30/7 day tiers RECOMMENDED.

Section 4.04 — Device Trust Credentials

Device Trust Credentials bind vault access to hardware-attested devices:

• Keyra Key on phone, laptop, security key
• Device registration with human approval
• Remote wipe revokes device keys without vault destruction
• New device registration requires existing trusted device or recovery workflow

Stolen device MUST NOT imply stolen vault root if device keys are partition-scoped.

Section 4.05 — Authorization Credentials

Human signing keys for KAAI grants, inheritance instruments, and high-risk vault operations reside in Identity Vault signing partition — hardware-backed where available. Signing operations require explicit human confirmation or pre-authorized automation scope with audit.

Section 4.06 — Identity Federation

Identity Vault federates attestations — not secrets — to Organization Graph and Family Trust Network:

• Proof of employment credential without exposing unrelated identity artifacts
• Age attestation for minor autonomy milestones without full birth certificate disclosure
• Professional license verification for agent scope validation

Federation uses selective disclosure protocols — W3C Verifiable Credentials interoperable.

Section 4.07 — Scenario — International Relocation

Human relocates country. Identity Vault retains prior passport archive; adds new residence permit. Device trust keys persist. Organization credentials revoke old tax ID refs; add new. Companion updates Life Graph Place nodes. No platform account recreation required — vault portability preserves continuity.

Section 4.08 — Identity Vault Security Requirements

• Government ID artifacts MUST encrypt with Identity partition key — never sync plaintext
• Credential display in Companion UI MUST mask sensitive fields — full reveal requires explicit tap
• Renewal reminders MUST NOT leak credential contents to notification surfaces
• Export of Identity Vault REQUIRES human passphrase re-entry
• Third-party identity verification receives selective disclosure proofs — not vault dump

Section 4.09 — Multi-Jurisdiction Identity

Humans holding multiple national identities — dual citizenship, residency permits, refugee travel documents — maintain parallel credential sets with jurisdiction tags. Agents and institutions receive only credentials tagged for their jurisdiction context. Cross-border identity correlation without human grant is prohibited.

PART V — Memory Vault

Section 5.01 — Purpose

The Memory Vault stores life memories — events, conversations, photos, videos, documents, achievements, milestones, family stories — with governance over retention, ownership, transfer, and deletion. Memory is the substance of autobiography; the Memory Vault is its secure body.

Section 5.02 — Memory Artifact Types

Embeddings for semantic recall MAY be stored in vault or derived on-device — MUST NOT leak to third parties without grant.

Section 5.03 — Memory Governance

Memory Governance policies attach per artifact or collection:

• visibility — private, family_core, family_extended, designated_individuals
• retention — indefinite, time-bounded, event-triggered deletion
• derivation — whether embeddings, summaries, Twin training permitted
• transfer — export allowed, federation allowed, inheritance designated
• deletion — sole owner vs joint consensus rules

Policies MUST be inspectable and modifiable by authorized owners.

Section 5.04 — Memory Retention

Memory Retention rules:

• Indefinite — default for human-designated precious memory
• Rolling — e.g., delete conversation logs older than 2 years unless flagged
• Milestone-anchored — retain until child reaches age of majority
• Legal — retain per compliance tag with auto-deletion on hold release

Automated retention execution MUST log deletions in audit trail. Accidental deletion SHOULD be recoverable via grace period where policy permits.

Section 5.05 — Memory Ownership

Memory Ownership models:

• Sole — single human; full control
• Joint — multiple humans; write per Family Constitution
• Contributory — multiple creators; each retains deletion right over contribution
• Inherited — beneficiary receives ownership post-succession — not mere copy

Platform claim of memory ownership via terms of service is void in Ecosystem implementations.

Section 5.06 — Memory Transfer

Memory Transfer mechanisms:

• Export pack to beneficiary vault
• Federation share with time-bounded read
• Migration to Family Memory Vault with ownership reassignment

Transfer MUST NOT remove human copy without explicit relinquish action.

Section 5.07 — Memory Deletion

Memory Deletion honors:

• Sole owner immediate delete
• Joint owner consensus or Constitution dispute process
• Inherited memory — beneficiary may delete received copy; cannot delete originator's retained copy unless sole-copy bequeathed

Right to be forgotten in shared memory MAY require anonymization rather than destruction where other parties hold interest — policy declared in advance.

Section 5.08 — Scenario — Parent and Child Shared Album

Parents and child co-contribute to Family Memory Vault album. Child's contributions are contributory — child can delete own photos at any age. Parents hold joint curation over album structure. At autonomy milestone, child gains read_private on own childhood memories stored in parent vault copies — staged per Family Constitution. Inheritance designates album to all siblings with joint ownership — not platform transfer.

Section 5.09 — Memory Integrity

Memory artifacts SHOULD maintain:

• Content hash for tamper detection
• Provenance chain — capture device, timestamp, location if authorized
• Edit history where modifications permitted
• Deepfake detection signals where media — advisory, not authoritative

Memory integrity supports legal admissibility and family trust — disputed photos trace provenance.

Section 5.10 — Sensory Memory Classes

Beyond visual and textual memory, vault supports:

Sensory memory governance identical to visual — retention, visibility, inheritance apply uniformly.

PART VI — Authorization Vault

Section 6.01 — Purpose

The Authorization Vault stores authorizations, delegations, approvals, certificates, trust relationships, and authority structures that govern who may act on the human's behalf — within vault, Life Graph, Companion, and agent ecosystems.

Section 6.02 — Authorization Artifact Types

Section 6.03 — Authorization Ledger

The Authorization Ledger is append-only hash-chained record of grant, exercise, and revocation events:

• grant_id, grantor, grantee, scope, conditions, issued_at, expires_at
• exercise_id linking vault access logs
• revocation_id with propagation timestamp

Ledger replicas MUST sync to authorized auditors — human, compliance officer — without exposing vault content.

Section 6.04 — Authorization Graph

The Authorization Graph — subgraph of Life Graph — models authority relationships:

• Human → grants → Companion
• Human → delegates → Agent
• Guardian → grants → ChildCompanion (bounded)
• Executor → administers → LegacyVault (inactive until trigger)

Graph stores structure; Authorization Vault stores signed certificate blobs.

Section 6.05 — Delegation Graph

The Delegation Graph tracks multi-hop delegations:

• Human grants attorney → attorney grants paralegal agent → agent requests document
• Each hop MUST cite parent grant; depth limits configurable
• Revocation at root propagates to all descendants

Delegation without human anchor at root is prohibited per KAAI Standard.

Section 6.06 — Standing vs Per-Action Authorization

Section 6.07 — Scenario — Agent Purchasing Delegation

Human grants KAAI shopping agent standing authorization: $200/month household supplies, approved vendors, no alcohol. Authorization Vault stores certificate; Authorization Graph edges visible in Companion. Agent each purchase cites certificate; ledger appends exercise. Human revokes — agent certificates invalid within SLA. Attempted purchase after revocation MUST fail at vault settlement boundary.

Section 6.08 — Authorization Review Cadence

Standing grants MUST include review cadence:

Companion surfaces upcoming expirations. Expired grants lapse to deny — no silent renewal.

Section 6.09 — Witness and Quorum Authorization

High-risk grants — Legacy instrument modification, large asset disposition, Companion succession — MAY require witness co-signatures per KAAI Standard. Witness keys registered in Authorization Vault; witness revocation invalidates future quorum formation, not past valid instruments absent fraud proof.

PART VII — Relationship Vault

Section 7.01 — Purpose

The Relationship Vault stores relationship attestations, trusted contacts, guardian designations, dependent mappings, and intimacy-scoped artifacts that complement Relationship edges in Life Graph — emergency contacts, godparent letters, co-parenting agreements, professional references.

Section 7.02 — Relationship Categories

Section 7.03 — Relationship Governance

Governance rules:

• Relationship artifacts link to Life Graph Relationship edges — consistency REQUIRED
• Trust score updates reflect relationship vault events — betrayal, repair
• Adding trusted contact requires mutual attestation where policy demands
• Removing relationship revokes dependent grants automatically

Section 7.04 — Relationship Portability

Relationship Portability — Relationship Vault exports with Life Graph relationship subgraph. Humans migrating platforms carry relationship attestations — not dependent on platform friend graph.

Section 7.05 — Relationship Succession

Relationship Succession on incapacity or death:

• Guardian edges activate per legal instrument
• Trusted contact emergency grants evaluate against current trust scores and Constitution
• Dependent humans receive notification via authorized channels

Relationship succession MUST NOT auto-grant financial or health write access without explicit instrument.

Section 7.06 — Scenario — Blended Family

Divorce dissolves marriage edge. Relationship Vault auto-revokes partner access to individual partitions per Family Constitution. Co-parenting agreement remains in Relationship Vault — governs child pickup grants. Children's Relationship Vaults retain both parent edges with scoped visibility. New partner adds relationship only with child age-appropriate consent process per policy.

PART VIII — Asset Vault

Section 8.01 — Purpose

The Asset Vault stores records pertaining to digital and physical assets — property, vehicles, financial accounts, insurance, contracts, intellectual property — with encrypted references to institutional systems and ownership documentation.

Section 8.02 — Asset Classes

Life Graph holds Asset nodes; Asset Vault holds sensitive values and document blobs.

Section 8.03 — Ownership Framework

Ownership attestation:

• owner human or joint designation
• beneficiary inheritance edges
• lien or encumbrance tags
• valuation optional with source and date

Joint assets require multi-signature for disposition grants per policy.

Section 8.04 — Digital Asset integrations

Digital assets — software licenses, media libraries, cryptocurrency — integrate without conflating wallet velocity with vault sovereignty:

• Wallet keys MAY reside in Asset Vault signing partition
• Transaction history summarized in Life Graph; details in vault
• Smart contract authorizations reference KAAI grants

Section 8.05 — Scenario — Estate Inventory

Executor receives administrative grant to Asset Vault inventory partition — views asset list, document refs, beneficiary designations — without immediate transfer of financial credentials. Staged release delivers account recovery instructions to beneficiary per Legacy Vault schedule. Audit logs all executor access. Human living grantor may revoke executor designation until trigger event.

PART IX — Health Vault

Section 9.01 — Purpose

The Health Vault stores health records, prescriptions, appointments, medical directives, emergency contacts, and care instructions under heightened governance — HIPAA-aligned overlays, clinician grant channels, patient-sovereign defaults.

Section 9.02 — Health Artifact Types

Section 9.03 — Healthcare Governance

Rules:

• Patient is root authority — clinicians receive time-bounded grants
• Break-glass emergency access logs and notifies patient when capable
• Research use requires explicit consent artifact — not blanket platform license
• Minor health vault under guardian key with autonomy progression

Section 9.04 — Companion and Agent Access

Health Companion agents — if authorized — read Health Vault within clinical advisory scope. Diagnostic agents MUST NOT write diagnoses to vault without licensed human clinician attestation. Medication reminders read prescription partition — no wholesale record export.

Section 9.05 — Federation with Providers

Provider Organization Graph nodes receive federated copies of records they generate — human retains master vault copy. Provider departure does not delete human vault.

Section 9.06 — Scenario — Emergency Room Visit

Human unconscious. Emergency Vault releases advance directive and allergy list to ER clinician via break-glass channel — temporary read, 24-hour expiry, audit notifies spouse and patient on recovery. Full Health Vault remains sealed. Clinician writes encounter summary to vault with patient retroactive approval request.

PART X — Family Vault

Section 10.01 — Purpose

The Family Vault aggregates family-governed partitions — records, memories, documents, instructions, archives, legacy assets — federating across Personal Trust Vaults per Family Trust Network instruments.

Section 10.02 — Family Vault Partitions

Section 10.03 — Family Vault Governance

Per Family Trust Network:

• Each member retains personal vault sovereignty
• Family partitions require explicit opt-in
• Family Constitution defines default templates — adoption requires affirmative consent
• Departure from family network triggers partition disconnection per policy — not data hostage

Section 10.04 — Co-Ownership Models

Section 10.05 — Cross-Generational Access

Grandparent read grant to family memory — teen write_private to own journal — child guardian_write for medical — autonomy milestones adjust automatically per Life Graph event triggers.

Section 10.06 — Scenario — Family Constitution Adoption

Family of five adopts Family Constitution template v2.1 — defines partition defaults, dispute resolution, inheritance staging. Constitution stored in Family Vault; signatures in Authorization Vault. Implementation activates Family Memory and Emergency partitions. Member declining Constitution participates in zero shared partitions — sovereignty preserved.

PART XI — Organization Vault

Section 11.01 — Purpose

The Organization Vault stores institutional artifacts — policies, contracts, research, knowledge, institutional memory, compliance records, audit trails — for organizations participating in the Organization Graph Enterprise Companion Framework. Organization vaults serve institutions while remaining subordinate to member human sovereignty for personal data.

Section 11.02 — Organization Vault Partitions

Section 11.03 — Organization Governance

Rules per Organization Graph:

• Employees hold personal Trust Vaults — never merged with Organization Vault
• Work credentials in Institutional Identity partition — revoked on departure
• Personal credentials, health, family vaults unaffected by employment termination
• Org Companion accesses Organization Vault within employment grant — not personal vault

Section 11.04 — Institutional Memory

Institutional memory — decisions, meetings, project history — stored with provenance:

• Author human reference
• Retention per regulatory sector
• Export for litigation hold with court order — personal vaults excluded unless relevant

Section 11.05 — Compliance and Audit

Compliance Vault maintains:

• Cross-reference to human authorization for agent actions in org context
• KAAI-LOG institutional shard
• Quarterly attestation reports for boards and regulators

Audit Vault is append-only — deletion prohibited except per legal destruction schedule with certificate.

Section 11.06 — Scenario — Employee Departure

Employee resigns. Organization Vault revokes all institutional grants within 24 hours. Employment contract moves to archived with legal retention tag. Personal research notes authored by employee — if contributory ownership — export to employee personal vault per IP policy. Org Companion loses access to employee personal Twin — employment edge removed.

Section 11.07 — Sector Overlays

Organization Vault implementations MAY activate sector-specific overlays:

Sector overlays MUST NOT weaken employee personal vault sovereignty.

Section 11.08 — Knowledge Continuity

When institutions dissolve — startup failure, merger, nonprofit closure — Organization Vault knowledge partitions export per wind-down policy. Employee-contributed personal knowledge returns to personal vaults. Institutional memory without human author attribution enters public archive only with explicit license — not default platform claim.

PART XII — Legacy Vault

Section 12.01 — Purpose

The Legacy Vault stores digital wills, inheritance instructions, family histories, life lessons, voice and video archives, personal messages, and companion succession designations — the intentional transmission of self across mortality.

Section 12.02 — Legacy Artifact Types

Section 12.03 — Legacy Architecture

Legacy Vault operates as inactive-until-trigger partition:

• Living human retains full control and revocation
• Preflight simulation shows beneficiary experience without premature release
• Trigger events: death certificate attestation, incapacity declaration, manual executor activation with quorum
• Multi-signature trigger RECOMMENDED — attorney + family executor + platform attestation

Section 12.04 — Companion Succession

Companion succession specifies:

• Successor human grant recipient
• Memory scope transfer vs archive-only
• Personality configuration inheritance bounds — successor may not be compelled to accept
• Retired Companion audit package for beneficiary review

Companion MUST NOT become autonomous heir — it serves successor human under new grant.

Section 12.05 — Staged Release

Stages enforceable cryptographically — premature decryption MUST fail.

Section 12.06 — Scenario — Multi-Beneficiary Legacy

Parent designates three children as Legacy beneficiaries with staggered releases — ethical will at death, financial instructions at probate completion, personal videos at each child's 30th birthday. Executor receives administrative grant only. Child attempting early access receives denial with audit entry. Parent updates Legacy Vault while living — prior staged versions archived with version chain.

Section 12.07 — Legacy Vault and Legal Instruments

Legacy Vault complements — does not replace — legal estate instruments:

• Digital will artifact references legal will document hash
• Executor grants align with probate court authority where applicable
• Beneficiary identity verification may require legal attestation in high-value estates
• Conflict between Legacy Vault and court order resolves per jurisdiction — human should reconcile during life

Implementations SHOULD support attorney co-signature workflows and notarization metadata attachment.

Section 12.08 — Values Transmission

Legacy Vault MAY encode Values nodes — ethical principles, religious commitments, political philosophies, charitable intentions — as structured artifacts inheriting to beneficiary Life Graphs. Values transmission is voluntary; beneficiaries may accept, modify, or archive without obligation to conform.

PART XIII — Companion Vault

Section 13.01 — Purpose

The Companion Vault stores companion identity, memory references, configurations, evolution history, trust scores, and lifecycle data — enabling Companion persistence across devices and generations without platform lock-in.

Section 13.02 — Companion Vault Contents

Section 13.03 — Companion Identity Persistence

Companion identity MUST survive:

• Device replacement — restore from vault backup
• App reinstallation — rebind to same Companion ID
• Model provider change — configuration migrates; model is replaceable

Companion identity MUST NOT be reassigned to different human without explicit export-import migration audit.

Section 13.04 — Memory Reference Architecture

Companion Vault stores references, not primary memory:

• Reduces duplication and divergence
• Memory governance remains in Memory Vault
• Companion requests resolve refs through Authorization Engine

Section 13.05 — Evolution History

Evolution history logs:

• Capability expansions with human approval timestamps
• Model version changes
• Policy template updates
• Trust score adjustments with causality

Beneficiary reviewing Companion succession inspects evolution history before accepting grant.

Section 13.06 — Scenario — Teen Autonomy Transition

Child Companion at age 13 transitions per Family Constitution. Companion Vault splits configuration — parental oversight features archive; teen-private memory refs rebind to teen's Personal Memory Vault. Same Companion ID persists — continuity of relationship. Parent read grants narrow per policy. Evolution history records transition event.

PART XIV — Agent Vault

Section 14.01 — Purpose

The Agent Vault stores KAAI agent identity, certificates, permissions, delegations, audit logs, trust scores, and retirement records — implementing agent persistence and accountability per KAAI Standard.

Section 14.02 — Agent Vault Contents

Section 14.03 — Agent Identity

Each authorized agent registered in human or organization Agent Vault:

• Unique Agent ID
• Purpose declaration
• Owner and sponsor references
• Class certification tags

Unregistered agents MUST NOT receive vault access.

Section 14.04 — Permission Storage

Agent permissions stored as signed certificates — not implicit API keys. Certificate fields:

• Scope enumeration
• Resource partition bindings
• Temporal bounds
• Condition predicates
• Human authorization root signature

Section 14.05 — Agent Audit Logs

Agent Audit Logs — Agent Vault maintains KAAI-LOG hash chain replicas:

• Correlatable with vault access logs
• Exportable for legal discovery
• Retained per human policy — minimum 7 years RECOMMENDED for financial agents

Section 14.06 — Agent Trust Scores and Agent Retirement Records

Agent Trust Scores history and Agent Retirement Records — retirement workflow:

Zombie agents — active certificates without owner review — SHOULD trigger trust decay alerts.

Section 14.07 — Scenario — Compromised Agent

Anomaly detection flags agent behavior. Human revokes Authorization Certificate via Companion. Agent Vault propagates revocation; KAAI registry updates. Vault access attempts fail. Audit reconstructs compromise window. Replacement agent registers with new Agent ID — no certificate reuse.

Section 14.08 — Agent Vault Federation

Organization Agent Vaults federate with human personal Agent Vaults when employment grants authorize:

• Work agent certificates stored in Organization Vault
• Personal agent certificates remain in personal Agent Vault
• Cross-boundary agent action requires explicit scope in both vaults
• Departure severs federation — work agents retire or transfer to org ownership

Section 14.09 — Agent Class Storage Requirements

Higher classes demand richer vault persistence — not optional logging.

PART XV — Encryption Architecture

Section 15.01 — Encryption Principles

All Trust Vault implementations MUST encrypt:

• Data at rest — all partitions
• Data in transit — all federation and sync
• Data on device — local replica encryption mandatory
• Metadata where feasible — partition listings, artifact titles

Encryption without human key custody is non-conformant.

Section 15.02 — At-Rest Encryption

At-rest model:

• AES-256-GCM or successor AEAD RECOMMENDED for blob encryption
• Per-artifact content keys encrypted with partition keys
• Partition keys derived from human root via HKDF with domain labels
• Unique nonce per write

Section 15.03 — In-Transit Encryption

In-transit requirements:

• TLS 1.3 minimum for network federation
• End-to-end encrypted sync payloads — custodian sees ciphertext only
• Certificate pinning for vault federation endpoints RECOMMENDED

Section 15.04 — Device Encryption

On-device storage:

• OS-level full-disk encryption assumed baseline
• Additional vault-layer encryption with Keyra Key binding
• Secure enclave for root key operations where hardware available
• Memory encryption for hot cache during active Companion sessions

Section 15.05 — Keyra Key

Keyra Key is the human-root cryptographic identity:

• Hardware-backed where available — TPM, Secure Enclave, HSM card
• Biometric or PIN unlock local — never transmitted
• Derives partition keys — never exports raw root to cloud
• Recovery via human-configured Shamir shares or recovery codes in Identity Vault

Loss of Keyra Key without recovery material implies vault inaccessibility — implementations MUST warn at setup.

Section 15.06 — Hardware Security

Hardware security requirements:

• Root key operations in secure element where device supports
• Side-channel resistant implementations for mobile
• Optional hardware security module for high-net-worth legacy configurations

Section 15.07 — Quantum-Resistant Strategy

Quantum-resistant migration strategy:

• Hybrid classical + post-quantum algorithms for key encapsulation during transition era
• Crypto-agility — cipher suite negotiation without vault format breakage
• Periodic risk assessment RECOMMENDED — NIST PQC standards adoption timeline
• Re-encryption campaigns when human unlocks vault — lazy migration acceptable

Long-horizon Legacy Vaults MUST document encryption generation in metadata for future migration.

Section 15.08 — Key Rotation

Rotation policies:

• Device keys — on compromise or annual
• Agent delegation keys — on revocation or expiry
• Human signing keys — human-initiated with overlap period
• Partition keys — on policy change or suspected exposure

Rotation MUST preserve access to historical ciphertext via key escrow chain internal to vault — not vendor escrow.

Section 15.09 — Encryption Compliance Profiles

Profiles compose — human selects at provisioning; may upgrade without vault recreation.

Section 15.10 — Breach Response

On suspected key compromise:

Breach response MUST complete core rotation within 15 minutes for consumer tier.

PART XVI — Access Architecture

Section 16.01 — Access Principles

Vault access operates default deny. Every access request evaluates:

Section 16.02 — Human Access

Human access via Keyra Key unlock:

• Full inspectability of owned partitions
• Grant and revoke authority
• Export and delete authority
• Inheritance instrument management

Human access cannot be suspended by platform — only by legal instrument human can challenge.

Section 16.03 — Companion Access

Companion access:

• Mediated through Authorization Engine
• Scoped to grants — memory write, credential read for travel, etc.
• Display purpose to human for high-sensitivity operations
• Companion MUST NOT hold standing root key

Section 16.04 — Family Access

Family access per Family Trust Network:

• Joint partition access per co-ownership model
• Guardian access to minor partitions — bounded, auditable
• Elder care grants — time-bounded, revocable by elder
• No family-wide master password

Section 16.05 — Organization Access

Organization access:

• Employment-scoped grants to Organization Vault only
• Institutional agents access via KAAI certificates — not employee personal vault
• Termination revokes org grants automatically

Section 16.06 — Government Access

Government access channels:

• Lawful warrant or court order presented through standardized interface
• Decryption occurs only for specified partitions and duration
• Human notification where law permits
• Challenge mechanism preserved
• No bulk surveillance backdoor — architectural prohibition

Section 16.07 — Emergency Access

Emergency access:

• Pre-registered Emergency Vault grants
• Break-glass clinical access with 24–72 hour expiry typical
• SOS triggers notify trusted contacts before wide release where latency permits
• Post-emergency audit mandatory — human reviews all accesses

Section 16.08 — Access Decision Matrix

Section 16.09 — Scenario — Layered Access Request

KAAI calendar agent requests health appointment read. Authorization Engine checks: agent certificate valid, scope includes health.appointment.read, human standing grant active, trust score above threshold. Companion presents summary to human for first access each month per policy. Access logged. Human later revokes health scope — subsequent requests fail.

PART XVII — Vault Inheritance

Section 17.01 — Inheritance Philosophy

Vault inheritance is succession of authority and artifacts — not account hijacking. The deceased or incapacitated human's sovereignty transfers according to Inheritance Instruments — never according to platform default, inactive account policy, or agent inference.

Section 17.02 — Family Inheritance

Family Inheritance succession workflows:

• Spouse receives Emergency and Health partitions per instrument
• Children receive staged Legacy releases
• Family Vault joint partitions resolve per Family Constitution — buyout, distribute, or maintain
• Guardian succession for dependent minors — court orders integrated

Section 17.03 — Companion Inheritance

Companion Inheritance succession per Section 12.04:

• Designated human receives Companion grant
• Companion Vault exports to successor's vault
• Retired Companion enters read-only archive mode for audit period
• No autonomous Companion self-succession

Section 17.04 — Agent Inheritance

Agent Inheritance succession:

• Human-owned agents retire on death unless instrument designates successor administrator
• Successor human must affirm agent grants — no automatic continuation
• Organization agents persist under institutional ownership — personal agent delegation ends

Section 17.05 — Organization Succession

Organization succession:

• Institutional vault governed by corporate continuity plan
• Employee personal vaults unaffected
• Org keys rotate per board resolution — human member vaults independent

Section 17.06 — Emergency Succession

Emergency succession during incapacity:

• Pre-designated healthcare proxy receives Health Vault break-glass grant
• Financial agent grant activates per durable power of attorney artifact in Legacy Vault
• Duration bounded — periodic review while incapacity continues
• Recovery restores full human authority — emergency grants auto-revoke

Section 17.07 — Legacy Execution

Legacy execution workflow:

Section 17.08 — Inheritance Anti-Patterns

Prohibited:

• Platform claiming inactive account assets after timeout
• AI inferring beneficiaries without instrument
• Family member accessing personal partitions without grant
• Executor exceeding administrative scope
• Premature Legacy release without trigger validation

Section 17.09 — Scenario — Simultaneous Spouse and Child Beneficiaries

Deceased designates spouse as primary Health and Emergency beneficiary; children receive Legacy Vault staged messages. Executor — sibling — receives inventory grant only. Trigger fires. Spouse verifies identity, receives health partitions immediately. Children receive notification of pending staged releases. Executor accesses asset inventory — cannot transfer financial credentials without separate financial instrument. Audit published to all adult family members.

Section 17.10 — Inheritance Dispute Resolution

When beneficiaries contest Legacy instrument:

• Vault enters dispute state — no new releases
• Last-known valid instrument version locked with hash proof
• Court order artifact MAY authorize alternate release — logged
• Mediation grants — read-only instrument view for neutral third party — human-configured
• Companion MUST NOT adjudicate disputes — presents facts only

Dispute resolution preserves audit integrity — no silent overwrites during conflict.

Section 17.11 — Minor Beneficiary Custody

Minor beneficiaries receive vault partitions under guardian key custody:

• Staged releases hold in escrow until autonomy milestone
• Guardian administers but does not own beneficiary-designated artifacts
• At majority, custody transfers to beneficiary Keyra Key ceremony
• Guardian access revokes automatically unless separate care grant exists

PART XVIII — Multi-Vault Architecture

Section 18.01 — Multi-Vault Composition

A Sovereign Human operates multiple vault domains simultaneously — Identity, Memory, Authorization, Relationship, Asset, Health, Family, Organization, Legacy, Companion, Agent — unified under Personal Trust Vault root with federation to external structures.

Section 18.02 — Inter-Vault Interactions

Section 18.03 — Federation Model

Federation model — vaults sync authorized subsets without central merge:

• Pairwise key exchange between family members
• Organization federation via employment edge
• Selective disclosure to government attestation services
• No global vault database of human secrets

Federation protocol requirements:

• Conflict resolution favors human explicit edit
• Vector clocks per artifact version
• Revocation propagates across federation edges within SLA

Section 18.04 — Reference Resolution Flow

Standard resolution flow (per Life Graph Architecture):

Section 18.05 — Cross-Vault Transactions

Cross-vault transactions — e.g., designating memory artifact as legacy asset — atomic where possible:

• Single human signature binds both partitions
• Rollback on partial failure
• Audit records cross-partition linkage

Section 18.06 — Vault Boundary Violations

Implementations MUST detect and reject:

• Agent reading Health Vault via Memory grant scope laundering
• Organization agent accessing Family Vault through employment credential
• Companion elevating scope without human confirmation
• Federation peer requesting partition outside exchange agreement

Section 18.07 — Scenario — Divorce and Vault Federation

Divorce event updates Life Graph marriage edge. Multi-vault orchestration:

• Relationship Vault revokes partner trusted contact grants
• Family Vault joint partitions enter dispute resolution per Constitution
• Authorization Vault invalidates partner delegations
• Memory Vault shared albums split per contributory ownership
• Asset Vault joint property enters disposition workflow
• Organization Vault unaffected — personal employment vaults independent
• Legacy Vault beneficiary designations human updates when ready

Single life event — coordinated vault response.

Section 18.08 — Multi-Vault Orchestration Engine

Implementations SHOULD provide a Vault Orchestration Engine — event-driven coordinator that applies cross-partition policies when Life Graph events fire:

Orchestration executes human-configured policies — never autonomous vault mutation without policy anchor.

Section 18.09 — Federation Trust Boundaries

Federation peers operate at declared trust tiers:

Peers MUST NOT request access above their tier. Violations trigger trust decay and federation suspension.

PART XIX — On-Device Architecture

Section 19.01 — Local-First Principle

The primary Trust Vault replica SHOULD reside on the Sovereign Human's trusted device — local-first operation ensures sovereignty survives network partition, vendor outage, and jurisdictional blocking.

Section 19.02 — Local Vault

The Local Vault on-device structure:

Section 19.03 — Local Encryption

Local Encryption stack:

• Root key in secure enclave
• Warm and cold stores encrypted with derived partition keys
• Hot cache cleared on session lock
• Remote wipe destroys local keys — federation replicas remain ciphertext without key

Section 19.04 — Local Memory

Local Memory — Companion memory operations:

• Semantic recall indexes on-device where possible
• Embeddings derived locally from authorized Memory Vault refs
• No cloud inference on vault plaintext without explicit grant

Section 19.05 — Local Graph

Local Graph — Life Graph replica co-located with vault:

• Structural queries local — sub-second for household scope
• Secret resolution local when artifact local
• Federation fetch for remote family/org artifacts with auth

Section 19.06 — Local Twin

Local Twin — Digital Twin state:

• Twin parameters and authorized models in vault partition
• Inference on-device where hardware sufficient
• Cloud inference requires encrypted ephemeral payload — default off

Section 19.07 — Local Authorization Cache

Local Authorization Cache:

• Active grants cached for performance
• Revocation propagates to cache within SLA
• Cache miss triggers vault Authorization Ledger read
• Stale cache MUST NOT authorize high-risk operations

Section 19.08 — Edge Architecture

Edge devices — wearables, home assistants, vehicles — hold scoped vault shards:

• Minimal secret subset for device function
• Device keys in Identity Vault device trust partition
• Compromise isolates shard — not root vault

Section 19.09 — Sync Topology

[Trusted Phone — primary replica]
    ↔ encrypted sync ↔ [Trusted Laptop]
    ↔ encrypted sync ↔ [Family member — authorized partition]
    ↔ encrypted sync ↔ [Custodian cloud — ciphertext only]
    ↔ [Edge devices — scoped shards]

Section 19.10 — Scenario — Offline International Travel

Human travels without network. Local vault serves passport ref, offline maps, health allergy list, emergency contacts. Companion operates fully. Memory captures journal entries — queue for federation sync on reconnect. Authorization cache honors standing grants. High-risk financial operation blocked — requires online human confirmation per policy. Sovereignty uninterrupted by connectivity.

Section 19.11 — Device Replacement Workflow

When human acquires new primary device:

Replacement MUST NOT require cloud vendor unlock if local backup or family recovery shard exists.

Section 19.12 — Resource Constraints

On-device vault on constrained devices — low storage, limited RAM — MAY operate tiered mode:

• Hot Identity and Health partitions local
• Cold Memory blobs custodian-backed with local index
• Graph structure always local — refs resolve to fetch on demand

Tiered mode is degradation of convenience — not sovereignty. Human controls tier policy.

PART XX — Future Scale

Section 20.01 — Scale Dimensions

The Trust Vault Architecture MUST scale across:

Section 20.02 — Sharding Strategy

Personal vaults shard by human root — no global secret database. Federation protocols route authorized requests without centralizing ciphertext. Regional custodians hold replicas respecting data residency.

Section 20.03 — Global Trust Infrastructure

At civilization scale, Global Trust Infrastructure provides:

• Cross-border inheritance recognition protocols
• KAAI registry federation
• Trust attestation without data merge
• Quantum migration coordination
• Disaster recovery mesh — no single jurisdiction owns all keys

Section 20.04 — Future Digital Economies

Companion Economies per Human Sovereignty Charter require vault support for:

• Asset attestations and proof of ownership
• Transaction authorization credentials
• Value-transfer audit chains
• Inheritance of digital economic rights

Economic activity without vault-backed authorization is ungoverned commerce.

Section 20.05 — Generational Persistence

Century-scale requirements:

• Format migration without semantic loss
• Legacy Vault encryption generation tracking
• Beneficiary chains across great-grandchildren never born
• Cultural memory preservation in Family Archive partitions
• Companion evolution history readable by historians with beneficiary grant

Section 20.06 — Performance Targets

At scale:

• Local vault operations — sub-100ms for credential retrieval
• Federation sync — incremental, authorized-only
• Inheritance execution — complete within 72 hours of validated trigger for standard estates
• Revocation propagation — global registry < 60 seconds for agent certificates

Section 20.07 — Inequality and Access

Architecture MUST NOT assume universal latest hardware. Conformant implementations SHOULD support:

• Low-cost devices with secure element minimum
• Community custodian models for humans without personal devices
• Guardian-assisted vaults for minors and incapacitated humans
• Humanitarian recovery protocols — without weakening cryptography for others

Section 20.08 — Civilizational Stakes

Societies that centralize human secrets in platform monopolies sacrifice sovereignty for convenience. Societies that abandon vault architecture inherit digital amnesia. The Trust Vault at scale is infrastructure for digital civilization — as essential as property records, as personal as memory, as enduring as lineage.

Section 20.09 — Population Scenarios

Scenario — Billion-device mesh: Each human operates 3–5 trusted devices plus edge shards. Federation sync incremental — only changed artifacts since last vector clock. Global registry shards by geographic region — no single query path for all human vaults.

Scenario — Agent explosion: Average human authorizes 20–50 agents — shopping, health, finance, travel, home, work. Agent Vault partition sizes remain bounded via certificate compression and retired agent archival. Trust decay retires unused agents automatically after policy inactivity threshold.

Scenario — Generational handoff: Great-grandparent Legacy Vault releases to great-grandchild never met in life. Staged video message plays on 18th birthday. Companion succession declined by beneficiary — archive mode preserves great-grandparent's Companion as historical artifact with read grant.

Section 20.10 — Research and Standards Alignment

Trust Vault Architecture aligns with emerging standards:

• W3C Decentralized Identifiers for vault root identity refs
• W3C Verifiable Credentials for selective disclosure
• NIST SP 800-series for cryptographic modules
• HL7 FHIR for Health Vault interoperability overlays
• ISO 27001 for custodian operational security

Alignment is interoperable, not dependent — vault sovereignty survives standards evolution via format migration layers.

PART XXI — Closing Declaration

Section 21.01 — On Ownership

Humans deserve to own their digital lives — not rent them from platforms that change terms, merge without consent, or dissolve with shareholder decisions. Ownership requires repository architecture that persists, encrypts, exports, and answers to the human root. The Trust Vault exists so ownership is engineering reality — not marketing language.

Ownership matters because without it, humans are tenants in their own stories.

Section 21.02 — On Memory

Memory is identity extended through time. A child's drawing. A wedding vow recording. A parent's advice never written down but spoken to a Companion. When memory lives on platforms that claim license, humans forfeit the past. When memory scatters without governance, humans lose themselves. Memory must be stored with intention, shared with consent, retained with policy, deleted with dignity, inherited with love.

Memory matters because a human without memory is a stranger to themselves — and to those who love them.

Section 21.03 — On Inheritance

Biological life ends. Digital life need not end in chaos. Children should not hack deceased parents' accounts. Executors should not beg platforms for access. Beneficiaries should not discover ethical wills in inaccessible formats. Inheritance must be designed, signed, staged, audited, and executed — with the same seriousness as property law, because digital life has become property of the soul.

Inheritance matters because death is certain and digital abandonment is preventable.

Section 21.04 — On Sovereignty

Sovereignty is the right to control one's existence — to grant, revoke, inspect, delete, and port. Sovereignty without vault architecture is a charter without courts. The Trust Vault is where sovereignty becomes operational — every access logged, every key human-rooted, every agent subordinate, every institution a guest.

Sovereignty matters because power without accountability corrupts — and unarchitected digital power corrupts absolutely.

Section 21.05 — On Technology and the Human Person

Technology promised to remember everything and delivered amnesia when vendors failed. It promised connection and delivered extraction. It promised assistance and delivered dependency without control. This ends here. Technology should serve the whole human life — identity, memory, health, family, work, legacy — under human authority, across devices, across generations, across mortality.

Section 21.06 — Timeless Commitment

We declare the Trust Vault Architecture the canonical secure repository framework for human digital life in the Keyra Companion Ecosystem — and a reference for any civilization that dares to treat humans as sovereign persons rather than data subjects.

The vault is not a folder. The vault is a trust. The trust belongs to the human. Always.

Section 21.07 — Invocation

To every human establishing their first vault: you claim what was always yours. To every parent archiving a child's milestones: you preserve what time would steal. To every elder preparing legacy: you extend love beyond breath. To every implementer building storage: map every byte to sovereignty — or do not build. Demand architecture worthy of human life.

Section 21.08 — Canonical Status

This instrument joins the founding frameworks of the Keyra Companion Ecosystem as the authoritative reference for secure repository architecture — Identity, Memory, Authorization, Relationship, Asset, Health, Family, Organization, Legacy, Companion, and Agent vaults; encryption and access; inheritance and federation; on-device persistence and global scale — for the century ahead and beyond.

Implementers of storage, sync, credential, health, estate, and agent systems must map every capability to explicit sections of this framework. Features without vault governance mapping are design defects. Features that weaken human root authority for institutional convenience are constitutional violations.

Researchers studying digital identity, cryptography, health informatics, estate law, gerontology, and human-computer interaction will find here a synthesis point — not replacing disciplinary knowledge, but translating it into durable architecture that engineers can build, auditors can verify, and humans can inherit.

Section 21.09 — On the Century Ahead

This framework is written for humans not yet born — whose great-grandparents today provision their first vaults. Cryptographic algorithms will change. Devices will change. Companions will evolve beyond present imagination. The invariants must not change: human root authority, encrypted persistence, governed access, portable export, dignified inheritance. Implementation may evolve; principles endure.

The Trust Vault is the ark — not of species, but of personhood across the digital flood.

Section 21.10 — Final Affirmation

We affirm that every human — infant, elder, refugee, billionaire, anonymous, celebrated — deserves a permanent trusted repository of their digital life, governed by their authority, accessible across mortality's threshold to those they love.

This is not a privilege of the technical elite. It is infrastructure of human dignity in the computational age.

The vault belongs to the human. The human belongs to themselves. Always.
