# Satoshium Suite Reconciliation — Interoperability Review Handoff Register **Date:** September 30, 2026 **Phase:** V — Final Reconciliation, Ratification & Close **Step:** 54 — Produce the Interoperability Review Handoff Register **Status:** COMPLETE — APPROVED --- ## Purpose This register defines the exact matters that must be examined during the upcoming **Satoshium Interoperability Review**. It is a handoff document. It does **not** perform the Interoperability Review. It does **not** reopen the institutional architecture settled during Suite Reconciliation. Its purpose is to preserve the boundary between: ```text Suite Reconciliation → defines roles, canonical objects, authority, semantic distinctions, relationship meanings, lifecycle boundaries, and whole-Suite architecture Interoperability Review → examines how independently governed institutions exchange, resolve, serialize, reference, hand off, and preserve governed information across institutional boundaries ``` The next review must consume the settled Suite architecture rather than redesign it. --- # Governing Handoff Rule > **Interoperability must preserve institutional identity, authority, provenance, canonical object ownership, relationship semantics, lifecycle distinctions, and historical traceability.** The Interoperability Review may determine: ```text interfaces reference contracts serialization schema compatibility resolution behavior handoff mechanics state propagation version propagation exchange constraints compatibility rules ``` It may not silently redefine: ```text institutional roles canonical object ownership authority boundaries relationship meanings lifecycle semantics Suite membership ``` --- # Settled Architecture the Review Must Treat as Fixed The Interoperability Review must begin with these decisions already settled: ```text Formal Suite institutions → 8 Atlas → Authoritative Intelligence → Jurisdiction Intelligence Package Navigator → Workflow Definition / Orchestration → Navigator Workflow Definition Certifier → Operational Certification → Certification Package Registry → Canonical Registration / Public Catalog → Satoshium Registry Entry (SREG) Chronicle → Historical Preservation → Chronicle Entry Anchor → Integrity Preservation → Integrity Reference Beacon → Discovery & Signals → Discovery Signal Attestor → Governed Attestation & Rule-Constrained Evaluation → Attestation → Trust Statement ``` The following distinctions are also settled and must not be reopened: ```text CONNECTION ≠ IDENTITY REFERENCE DOES NOT TRANSFER AUTHORITY REFERENCE ≠ DERIVATION ≠ SUPPORT AUTHORITY ≠ PROVENANCE CANONICAL CREATION ≠ LIFECYCLE ACTIVATION ≠ PUBLICATION VALIDATION ≠ CONFORMANCE VALIDATION ≠ EVALUATION VERIFICATION ≠ CERTIFICATION EVALUATION OUTCOME ≠ TRUST STATEMENT CONCEPTUAL SEQUENCE ≠ MANDATORY PIPELINE EXERCISED LINEAGE ≠ MANDATORY ARCHITECTURE ``` --- # IR-001 — Cross-Institution Reference Contract ## Review Question What is the minimum governed information that must accompany a cross-institution reference so the receiving institution can interpret it without absorbing source authority? ## Candidate Reference Context The existing Attestor Reference Profile provides a strong starting point: ```text Identifier Source Provenance Type Status Scope Relationship Authority ``` Additional context may be required where applicable: ```text Version Identity Lifecycle State Publication State Limitations Source-Specific Context Canonical Public Reference ``` ## Interoperability Review Must Determine ```text minimum required fields optional fields institution-specific extensions authority declaration behavior provenance requirements version/state representation limitation representation unknown / unavailable field handling ``` ## Must Preserve > **Reference does not transfer authority.** ## Status ```text DEFERRED TO INTEROPERABILITY REVIEW ``` --- # IR-002 — Machine Serialization & Schema Compatibility ## Review Question How should cross-institution references and shared exchange structures be represented machine-readably without forcing all institutions into one canonical schema? ## Review Must Examine ```text common reference envelope vs institution-specific payloads shared field names required vs optional fields identifier representation authority / provenance representation relationship serialization lifecycle / publication state serialization version representation unknown values unsupported values extension mechanisms backward compatibility validation expectations ``` ## Boundary A shared interoperability schema must not become a new canonical Suite object unless separately governed. ## Status ```text DEFERRED TO INTEROPERABILITY REVIEW ``` --- # IR-003 — Stable Identifier & Reference Resolution ## Review Question How should an identifier reliably resolve to the correct governed public or machine-readable representation over time? ## Review Must Examine ```text canonical identifier resolution human-readable resolution machine-readable resolution version-specific references current vs historical resolution superseded object resolution withdrawn object resolution moved public paths durable redirect behavior broken-link handling reference persistence ``` The review must also preserve: ```text matching numeric suffixes across institutions ≠ relationship ≠ lineage ≠ identity ``` ## Status ```text DEFERRED TO INTEROPERABILITY REVIEW ``` --- # IR-004 — Source-State & Version-Change Propagation ## Review Question When an upstream referenced object changes, what must a downstream institution know, preserve, detect, or reevaluate? ## Review Must Examine ```text source version change source lifecycle change source publication change source supersession source withdrawal source correction source identifier continuity material vs non-material source change historical evaluated state later source state downstream review trigger downstream reevaluation trigger downstream republishing implications ``` The review must preserve the distinction: ```text Source State at Evaluation ≠ Later Source State ``` It must not silently rewrite the historical basis on which an earlier institutional determination was made. ## Status ```text DEFERRED TO INTEROPERABILITY REVIEW ``` --- # IR-005 — Navigator Workflow Handoffs ## Review Question What exactly does Navigator pass to a participating institution, and what does that institution return? ## Review Must Examine ```text workflow invocation context input references expected response structure institutional endpoint identification workflow-local state failure states timeout / unavailable states partial completion institutional rejection institutional output references completion reporting retry behavior handoff traceability ``` ## Must Preserve ```text Navigator owns → Navigator Workflow Definition → workflow-local orchestration state Participating institution owns → its canonical object → its institutional decision → its lifecycle → its publication ``` > **Workflow State ≠ Canonical Institutional State.** ## Status ```text DEFERRED TO INTEROPERABILITY REVIEW ``` --- # IR-006 — Registry Source-Object Exchange Mechanics ## Review Question How should Registry consume, reference, and maintain registration information about canonical source objects without duplicating or replacing those source objects? ## Review Must Examine ```text source identity resolution source institution declaration source version identity source lifecycle state source publication state source correction behavior source supersession behavior Registry metadata updates Registry metadata vs source metadata source unavailability source reference health registered-item historical continuity ``` ## Must Preserve ```text Source Institution → owns Source Object Registry → owns SREG ``` > **Registration does not transfer source authority.** ## Status ```text DEFERRED TO INTEROPERABILITY REVIEW ``` --- # IR-007 — Beacon Discovery Exchange Mechanics ## Review Question How should Beacon discover, reference, and expose governed source objects consistently across the Suite? ## Review Must Examine ```text stable source references source authority context source provenance source lifecycle state source publication state Discovery Metadata exchange Discovery Signal return to Navigator references to Registry references to Chronicle references to Anchor references to Certifier references to Atlas references to Attestor source-change reflection stale-discovery handling ``` ## Must Preserve ```text Discovery Signal → Beacon canonical object Discovery Metadata → supporting structure Discovery ≠ Verification ``` ## Status ```text DEFERRED TO INTEROPERABILITY REVIEW ``` --- # IR-008 — Attestor Governed-Input Ingestion ## Review Question How should Attestor ingest governed references from other institutions while preserving source authority and freezing the correct evaluation basis? ## Review Must Examine ```text mapping source object to governed reference required Reference Profile fields source authority declaration source provenance preservation copy vs reference behavior version identity source lifecycle state source publication state evaluation-basis snapshot source-state freezing post-evaluation source change detection reevaluation trigger unsupported source context external-source ingestion ``` ## Must Preserve ```text Referenced Authority ≠ Attestor Authority Source Object ≠ Attestation Evaluation Outcome ≠ Trust Statement ``` ## Status ```text DEFERRED TO INTEROPERABILITY REVIEW ``` --- # IR-009 — Common Relationship Serialization ## Review Question How should the settled relationship vocabulary be represented consistently across machine-readable institutional records? ## Settled Relationship Vocabulary ```text references derived-from supports evaluates results-in supersedes corrects related-to ``` ## Review Must Examine ```text relationship type field subject / object direction source identifier target identifier authority context relationship provenance effective time version scope relationship status relationship removal / supersession multi-hop relationships unknown relationship type handling ``` ## Must Preserve ```text Reference ≠ Derivation Reference ≠ Support Evaluates ≠ Results-In Supersedes ≠ Corrects ``` The review may standardize representation. It may not redefine meaning. ## Status ```text DEFERRED TO INTEROPERABILITY REVIEW ``` --- # IR-010 — External-System Interoperability Boundary ## Review Question How should Suite institutions interact with external systems while preserving the same authority and provenance discipline used internally? ## Review Must Examine ```text external source identity external authority declaration external provenance requirements external versioning external lifecycle/status mapping external source changes external identifier stability permitted copied fields reference-only fields evidence retention external schema mapping API use protocol use transport mechanisms authentication where applicable failure / unavailability behavior ``` ## Important Boundary The current Suite architecture does **not** require any particular: ```text external standard API transport protocol ``` The Interoperability Review may determine whether one or more are useful or necessary. It must not assume one in advance. ## Status ```text DEFERRED TO INTEROPERABILITY REVIEW ``` --- # IR-011 — Inter-Institution Validation Expectations ## Review Question When one institution consumes another institution's object or reference, what may it safely rely on about the source's Validation or Conformance state? ## Review Must Examine ```text whether Validation state is transmitted whether Conformance state is transmitted whether source validation evidence is referenced whether downstream institution revalidates structure locally how unknown Validation state is represented how stale Validation state is represented how source-specific rules remain source-specific ``` ## Must Preserve ```text Valid ≠ True Validation ≠ Conformance Source Validation ≠ Downstream Institutional Determination ``` ## Status ```text DEFERRED TO INTEROPERABILITY REVIEW ``` --- # IR-012 — Cross-Institution Historical Traceability ## Review Question What minimum cross-institution trace must exist so a downstream object can be reconstructed historically? ## Review Must Examine ```text source identifier source version source state at use timestamp of use relationship type provenance authority context workflow context where relevant later source changes correction history supersession history ``` The goal is reconstructability without duplicating entire source records. ## Status ```text DEFERRED TO INTEROPERABILITY REVIEW ``` --- # IR-013 — Failure, Partial Availability & Unknown-State Handling ## Review Question How should interoperability behave when an institution, object, reference, or required field is unavailable? ## Review Must Examine ```text source unavailable reference unresolved version unavailable required field unavailable authority unknown provenance incomplete schema unsupported relationship unresolved institution offline partial response stale cached representation temporary transport failure ``` ## Must Preserve > **UNKNOWN ≠ SUCCESS** And: > **NOT-TESTED ≠ PASS** ## Status ```text DEFERRED TO INTEROPERABILITY REVIEW ``` --- # IR-014 — Cross-Institution Compatibility Versioning ## Review Question How should interoperability contracts evolve without silently breaking existing production objects or references? ## Review Must Examine ```text reference-profile versioning schema versioning compatibility ranges forward compatibility backward compatibility deprecated fields new controlled values unsupported versions migration behavior historical record preservation ``` ## Boundary Compatibility versioning must not mutate historical canonical objects merely to match a newer interface. ## Status ```text DEFERRED TO INTEROPERABILITY REVIEW ``` --- # IR-015 — Interoperability Security & Trust Boundary ## Review Question What interoperability controls are needed so exchanged references cannot falsely imply authority, provenance, validation, or institutional endorsement? ## Review Must Examine ```text source authenticity reference integrity tampered payload detection false authority claims false provenance claims identifier spoofing stale reference substitution untrusted external input schema manipulation relationship-type manipulation ``` ## Boundary Security mechanisms may protect exchange. They do not create substantive institutional authority. ## Status ```text DEFERRED TO INTEROPERABILITY REVIEW ``` --- # Explicitly Out of Scope for Interoperability Review The following matters are settled and should not be reopened merely because implementation details are being reviewed: ```text formal Suite roster Aegis boundary institutional roles canonical object ownership Atlas canonical package model Navigator canonical object Certifier canonical object Registry SREG identity Chronicle Entry identity Anchor Integrity Reference identity Beacon Discovery Signal identity Attestor Attestation / Trust Statement identities SYS-* vs SREG-* authority boundaries Authority ≠ Provenance Reference does not transfer authority Connection ≠ Identity Reference ≠ Derivation ≠ Support Canonical Creation ≠ Lifecycle Activation ≠ Publication Validation ≠ Conformance Verification ≠ Certification Evaluation Outcome ≠ Trust Statement Conceptual Sequence ≠ Mandatory Pipeline Exercised Lineage ≠ Mandatory Architecture ``` If an implementation proposal appears to require changing one of these settled points, that is not an ordinary interoperability implementation decision. It must be explicitly escalated as an architectural conflict. --- # Expected Interoperability Review Deliverables The next review should determine whether the following formal records are warranted: ```text Suite Interoperability Reference Contract Cross-Institution Reference Profile Interoperability Schema / Serialization Standard Identifier & Reference Resolution Model State / Version Propagation Model Navigator Handoff Contract Registry Exchange Model Beacon Exchange Model Attestor Governed-Input Ingestion Model Relationship Serialization Standard External-System Interoperability Boundary Failure / Unknown-State Handling Standard Compatibility / Versioning Model ``` The exact names may change during that review. The subjects should not be silently omitted. --- # Interoperability Review Entry Conditions The next review may begin because Suite Reconciliation has established: ```text institutional roles → coherent canonical objects → coherent controlled terminology → coherent authority boundaries → coherent relationship semantics → coherent lifecycle / publication semantics → coherent operational status → coherent ``` The remaining work is therefore primarily: ```text technical exchange compatibility serialization resolution handoffs state propagation version propagation failure behavior ``` rather than institutional redesign. --- # Handoff Summary ```text Suite-level architecture requiring reopening → NONE Detailed interoperability matters → IDENTIFIED Authority redesign required → NO Canonical object redesign required → NO Relationship-semantic redesign required → NO Primary next-review focus → References → Schemas → Serialization → Resolution → Handoffs → State / Version Propagation → Compatibility → Failure Handling → External Boundaries ``` --- # Final Disposition # INTEROPERABILITY REVIEW HANDOFF REGISTER — COMPLETE — APPROVED This register defines what the upcoming Interoperability Review must examine while explicitly preserving the architectural decisions completed during Suite Reconciliation. The handoff is intentionally bounded: > **Examine how the institutions interoperate. Do not redesign what the institutions are.**
