Version: 1.0.0
Status: Adopted
Date: 2026-08-02

1. Purpose

SensOS Open Standards are organized into RFC namespaces. Existing namespaces remain unchanged. Two new namespaces are introduced:

NamespaceRole
RFC-MMMeaning Mapper product specification
RFC-ITMImplementation traceability & evidence (cross-cutting)

Canonical draft corpus (engineering workspace): RFCv3_draft/rfc/.

2. Namespace architecture

RFC-PROCESS / RFC-ARCH

        ├── RFC-CORE
        ├── RFC-HEXT
        ├── RFC-HEKB
        ├── RFC-MCP
        ├── RFC-CAL
        ├── RFC-SensOS
        ├── RFC-MM      ← Meaning Mapper product (NEW)
        └── RFC-ITM     ← Traceability (NEW, cross-cutting)

Unchanged namespaces: CORE, HEXT, HEKB, MCP, CAL, SensOS, ARCH, PROCESS.
Do not rename or renumber existing RFCs.

3. RFC-MM roadmap

RFCTitle
RFC-MM001Meaning Mapper Architecture
RFC-MM002Meaning View ABI
RFC-MM003Meaning Payload Schema
RFC-MM004Meaning Runtime Bridge
RFC-MM005Meaning Mapper Service API
RFC-MM006Provider SPI (future)
RFC-MM007Conformance Test Suite (future)
RFC-MM008Certification (future)
RFC-MM009Streaming Protocol (future)
RFC-MM010MCP Integration (future)

Reference service: Meaning Mapper.

4. RFC-ITM roadmap

RFCTitle
RFC-ITM001Implementation Traceability Framework
RFC-ITM002Evidence Format
RFC-ITM003Repository Mapping
RFC-ITM004Implementation Readiness Matrix
RFC-ITM005Certification Traceability

RFC-ITM is independent of products. It applies equally to CORE, HEXT, HEKB, MCP, CAL, SensOS, Meaning Mapper, and future products.

5. Legacy RFC-SA → RFC-MM

RFC-SA001–005   (historical)

       ▼ Superseded
RFC-MM001–005   (canonical)

RFC-SA005SupersededRFC-MM005

Historical RFCs remain archived for traceability. They MUST NOT drive new architecture.
