Through MCP (Priority: P1) + +As a downstream developer, I want one dedicated Traverse MCP server so that I can discover governed capabilities and workflows and invoke them through MCP without reimplementing Traverse runtime behavior. + +**Why this priority**: Your chosen architecture makes Traverse the runtime and MCP substrate under apps like `youaskm3`, so MCP must become a usable product surface rather than a theoretical future. + +**Independent Test**: Start the server in the first supported host mode, list the governed entrypoints it exposes, invoke at least one governed execution path, and verify the result is produced through runtime-authoritative behavior. + +**Acceptance Scenarios**: + +1. **Given** a local downstream client connects through the supported MCP host mode, **When** it lists available Traverse entrypoints, **Then** it receives a deterministic machine-readable description of the governed MCP surface. +2. **Given** a client invokes one governed capability or workflow-backed capability, **When** execution begins, **Then** the server delegates to Traverse runtime authority instead of bypassing runtime validation. +3. **Given** a requested execution fails validation or runtime checks, **When** the client inspects the MCP result, **Then** the failure remains structured and explainable. + +### User Story 2 - Expose a Rich but Product-Shaped MCP Surface (Priority: P1) + +As a downstream app or agent-tool developer, I want a richer MCP surface than bare discovery so that Traverse can support real product consumption rather than only low-level metadata inspection. + +**Why this priority**: The UMA Chapter 13 reference app proved that a richer MCP surface is more useful in practice, but Traverse needs that richness without inheriting chapter-specific semantics. + +**Independent Test**: Inspect the governed MCP toolset and verify that it includes Traverse-native discovery and execution plus a generic workflow-oriented convenience layer, without hard-coding expedition or chapter-specific scenario vocabulary into the core. + +**Acceptance Scenarios**: + +1. **Given** a client needs basic product operations, **When** it inspects the core MCP surface, **Then** it can list and describe capabilities and workflows, run them, and render execution artifacts. +2. **Given** a client wants a friendlier workflow-oriented surface, **When** it inspects the convenience layer, **Then** it sees generic entrypoint-oriented operations rather than chapter-specific scenario language. +3. **Given** the expedition example remains the first proving domain, **When** the client uses the convenience layer, **Then** the surface stays product-generic rather than domain-locked. + +### User Story 3 - Keep Traverse Runtime Authoritative Behind MCP (Priority: P1) + +As a platform steward, I want the MCP server to remain a thin façade over Traverse runtime authority so that validation, state transitions, trace semantics, and execution policy do not drift behind an MCP-specific execution path. + +**Why this priority**: The strongest architectural lesson from the UMA runtime model is that the runtime, not the transport surface, stays authoritative. + +**Independent Test**: Review one governed MCP execution path and verify that request validation, candidate selection, execution, runtime-state behavior, and terminal results still flow through the Traverse runtime model. + +**Acceptance Scenarios**: + +1. **Given** a client invokes MCP execution, **When** the server handles the request, **Then** it translates the request into governed Traverse runtime execution rather than directly running business logic. +2. **Given** the runtime emits terminal results and trace outputs, **When** the MCP server returns or renders those artifacts, **Then** it does not redefine their semantics. +3. **Given** future host modes are added, **When** they are proposed, **Then** this slice still preserves runtime-authoritative execution as a non-negotiable boundary. + +## Scope + +In scope: + +- first dedicated Traverse MCP server model +- first supported `stdio` host mode +- Traverse-native

Functional Requirements + +- **FR-001**: Traverse MUST define one dedicated MCP server model as a first-class product surface. +- **FR-002**: The first supported MCP host mode MUST be `stdio`. +- **FR-003**: This slice MUST explicitly allow future host modes later without making them part of the first implementation requirement. +- **FR-004**: The MCP server MUST remain a thin façade over Traverse runtime execution. +- **FR-005**: MCP requests that trigger execution MUST be translated into governed Traverse runtime requests rather than directly executing business logic inside the server. +- **FR-006**: The MCP server MUST expose Traverse-native core operations for discovery and description of governed capabilities and workflows. +- **FR-007**: The MCP server MUST expose Traverse-native execution operations for both direct capability execution and workflow-backed capability execution. +- **FR-008**: The MCP server MUST expose a generic workflow-oriented convenience layer for entrypoint-style discovery, description, execution, and execution-artifact rendering. +- **FR-009**: The convenience layer MUST remain product-generic and MUST NOT hard-code chapter- or domain-specific scenario semantics into the core server contract. +- **FR-010**: The first dedicated MCP server MUST support exposure of governed WASM-hosted capabilities or agents through approved manifests and contracts. +- **FR-011**: The MCP server MUST preserve governed validation before execution begins. +- **FR-012**: The MCP server MUST preserve machine-readable runtime failure behavior when validation or execution fails. +- **FR-013**: The MCP server MUST support rendering one structured execution artifact, such as a trace-derived or terminal-result-derived report, through the MCP surface. +- **FR-014**: The MCP server MUST expose enough machine-readable metadata for a downstream client to identify what is invocable and what input shape it expects. +- **FR-015**: The MCP server MUST remain aligned with the downstream-consumer contract and MCP validation slices rather than redefining them separately. +- **FR-016**: The first server implementation MUST be broad enough to feel product-usable and MUST NOT stop at discovery-only metadata inspection. +- **FR-017**: Approved implementation under this slice MUST be decomposable into multiple production-grade tickets with independent validation, not one unreviewable monolith. +- **FR-018**: Approved implementation and validation under this slice MUST be checked against this governing spec before merge. + +## Non-Functional Requirements + +- **NFR-001 Runtime Authority**: Validation, execution, state transitions, and terminal semantics MUST remain runtime-authoritative behind the MCP façade. +- **NFR-002 Determinism**: Discovery ordering, entrypoint description, execution behavior, and failure reporting MUST remain deterministic for equivalent inputs and registry state. +- **NFR-003 Product Boundary**: The first dedicated MCP server MUST stay product-shaped and reusable, not chapter-shaped or demo-specific. +- **NFR-004 Explainability**: MCP-visible outputs for execution, failure, and rendered artifacts MUST remain explainable without private internal logs. +- **NFR-005 Testability**: The dedicated server model MUST be specifiable and implementable in slices that support deterministic local and CI validation. +- **NFR-006 Portability**: The server model MUST preserve portability of governed WASM-hosted capabilities and agents across supported Traverse hosts, even though the first server host mode is `stdio`. +- **NFR-007 Maintainability**: Core Traverse-native operations and convenience-layer operations MUST remain separable so future surface growth does not pollute the core server boundary. + +## Non-Negotiable Quality Gates + +- **QG-001**: Traverse MUST NOT present the first dedicated MCP server as authoritative for execution logic; Traverse runtime remains authoritative. +- **QG-002**: The first dedicated MCP server MUST NOT depend on undocumented app-specific glue or private repo semantics. +- **QG-003**: The first dedicated MCP server MUST

entrypoint-shaped façade over core Traverse semantics. +- **MCP Entrypoint Record**: One machine-readable description of an invocable governed capability or workflow-backed capability exposed through the server. +- **MCP Rendered Artifact**: One structured report or trace-derived representation returned by an MCP operation without redefining the underlying runtime semantics. + +## Success Criteria + +- **SC-001**: Traverse has one explicit governed model for a dedicated MCP server package rather than only MCP foundation pieces. +- **SC-002**: A downstream client can understand the first server host mode, core operations, convenience operations, and runtime-authoritative boundary from this spec alone. +- **SC-003**: The first implementation can be split into multiple production-grade tickets

Story 1 - Register and Sync Trusted Peers (Priority: P1) + +As a Traverse operator, I want to register trusted peers and manually sync registry state so that distributed Traverse instances can

on a remote peer to be invoked through the owning peer so that federation is useful as a real end-to-end execution path, not just a registry mirror. + +**Why this priority**: Federation must deliver a real cross-peer call path; otherwise it only proves discovery and state replication. + +**Independent Test**: A reviewer can verify that a discovered remote capability is routed to its owning peer, that the result or failure is returned, and that trace provenance is preserved. + +**Acceptance Scenarios**: + +1. **Given** a capability is registered on peer B and synced to peer A, **When** peer A invokes that capability, **Then** the request is routed to peer B and the response is returned with cross-peer provenance. +2. **Given** the owning peer is unavailable, **When** peer A invokes the remote capability, **Then** the failure is explicit, retryable if policy allows, and the trace records the reason. + +### User Story 3 - Trust, Visibility, and Auditability Across Peers (Priority: P2) + +As a federation steward, I want remote registry entries to be validated against local approved specs and tracked with audit evidence so that federation remains governable and explainable over time. + +**Why this priority**: The federation model needs a durable trust story and reviewable evidence so the system can grow without becoming opaque. + +**Independent Test**: A reviewer can confirm that remote entries are validated before acceptance, peer visibility is exposed, and conflicts or rejections produce audit evidence. + +**Acceptance Scenarios**: + +1. **Given** a remote registry entry from a trusted peer, **When** it is synced, **Then** the entry is validated against the local approved spec registry before acceptance. +2. **Given** a sync detects a divergent or conflicting entry, **When** the sync completes, **Then** the conflict is reported with audit evidence instead of being silently hidden. +3. **Given** an operator inspects federation state, **When** they query peers and

peers. +- **FR-003**: Traverse MUST expose peer listing and sync status to operators and agents. +- **FR-004**: Traverse MUST validate remote registry entries against the local approved spec registry before accepting them. +- **FR-005**: Traverse MUST federate capability, event, and workflow registry entries through the first governed sync path. +- **FR-006**: Traverse MUST route a discovered remote capability invocation to the owning peer. +- **FR-007**: Traverse MUST preserve cross-peer trace provenance for routed invocations. +- **FR-008**: Traverse MUST produce explicit failure evidence when the owning peer is unavailable. +- **FR-009**: Traverse MUST report conflicts or divergent registry entries with audit evidence. +- **FR-010**: Traverse MUST preserve public/private visibility rules across peers and deny unauthorized access to private registry entries. +- **FR-011**: Approved implementation under this slice MUST be checked against the governing federation spec before merge. +- **FR-012**: Future federation extensions beyond this slice MUST be split into separate tickets rather than expanded in place. + +### Key Entities *(include if feature involves data)* + +- **FederationPeer**: A trusted Traverse instance participating in federation, identified by peer identity and trust metadata. +- **PeerRegistrySnapshot**: A synchronized view of the capability, event, and workflow registry entries received from a peer. +- **FederationSyncSession**: A single manual sync operation with outcome, timing, and validation evidence. +- **FederatedInvocation**: A routed request sent to the owning peer and the resulting response or failure. +- **TrustRecord**: The approved relationship that allows a peer to participate in federation. +- **ConflictRecord**: Audit evidence that records divergent or conflicting registry entries. +- **CrossPeerTraceProvenance**: Evidence showing which peer owned the invocation and how the result returned. + +## Success Criteria *(mandatory)* + +### Measurable Outcomes + +- **SC-001**: A reviewer can register a peer, run a manual sync, and verify the peer and sync outcome without reading implementation code. +- **SC-002**: A discovered remote capability can be invoked through the owning peer and return a recorded response or explicit failure. +- **SC-003**: Remote entries are accepted only after local approved-spec validation, and rejected entries produce reviewable evidence. +- **SC-004**: Peer list, sync status, and conflict evidence are visible through the supported operator surface. +- **SC-005**: Cross-peer provenance is present in routed invocation evidence and can be reviewed after the call completes. + +## Assumptions + +- The first governed federation slice is peer-to-peer and does not require a central coordinator. +- The first supported sync path is manual and on-demand. +- The first supported transport path is explicit and reviewable rather than inferred from internal implementation structure. +- Future improvements such as automatic sync, streaming updates, and central coordination will be tracked as separate tickets. +- The federation model must stay compatible with the approved spec registry and the existing runtime/tracing model. + +## Governing Relationship + +This specification is intended to govern the following open issues: + +- #213 Implement multi-instance registry federation +- #214 Implement cross-instance capability invocation +- #215 Distributed governance and trust model + +This specification is governed by: + +- `001-foundation-v0-1` +- `019-downstream-consumer-contract` +- `020-downstream-integration-validation` +- `021-app-facing-operational-constraints` + +This specification also preserves the current bounded future-work model: + +- [#236](https://github.com/enricopiovesan/Traverse/issues/236) automatic federation sync after peer registration +- [#237](https://github.com/enricopiovesan/Traverse/issues/237) central federation coordinator +- [#238](https://github.com/enricopiovesan/Traverse/issues/238) federation conflict auto-resolution policy +- [#239](https://github.com/enricopiovesan/Traverse/issues/239) streaming federation sync transport + +coordinator behavior, automatic sync, streaming updates, and other nonessential federation extensions remain future tickets From c0a0eaad0f29b414a92dbe0eb3c3c565e98b6a11 Mon Sep 17 00:00:00 2001 From: Enrico Piovesan Date: Fri, 10 Apr 2026 11:21:58 -0600 Subject: [PATCH 5/7] Expand workflow
