+# UMA Pistis Pantheon Registry
+
+This document records the current human-readable naming registry for the local-first SourceOS/SociOS execution model discussed across the SourceOS-Linux and SociOS-Linux repos. It is intentionally *descriptive first* and is meant to guide follow-on contract work in `schemas/`, `openapi*.yaml`, and `asyncapi*.yaml`.
+
+The registry does **not** replace typed contracts. It explains where named platform concepts belong in the ecosystem and how they should map into the canonical contract layer.
+
+---
+
+## Why this document exists
+
+The current SourceOS/SociOS spec already defines the two-plane model, typed governance objects, workflow/provenance primitives, and the agent plane. What it does **not** yet do is capture the naming and repo-placement decisions for the local-first Linux platform being assembled across:
+
+- `SourceOS-Linux/sourceos-spec`
+- `SociOS-Linux/source-os`
+- `SociOS-Linux/agentos-spine`
+- `SociOS-Linux/workstation-contracts`
+- `SociOS-Linux/socios`
+
+This document makes those boundaries explicit so that future schema work stays additive and lands in the right repo.
+
+---
+
+## Canonical naming registry
+
+| Surface | UI name | Code slug | Primary role | Upstream home |

+
+---
+
+## Repo placement rules
+
+### 1. `sourceos-spec` is the canonical contract home
+
+Anything that needs a stable machine-readable shape belongs here first:
+
+- identity and attestation payloads for MICHAEL
+- PRAXIS action envelopes, verbs, witnesses, and replay semantics
+- ASHAMAAT consensus receipts, validator set records, and anchors
+- PHAROS / ARIADNE event channels and headers
+- IANUS corridor and path policy objects
+- Codex manifests, object references, anchors, and visibility labels
+- Kairos and Shiloh policy documents
+
+### 2. `source-os` is the immutable substrate
+
+Anything that is about Linux host posture, persistent encrypted volumes, OSTree roots, or local-first fallback posture belongs in `source-os` rather than the spec repo.
+
+### 3. `agentos-spine` is the integration/workspace assembly repo
+
+Anything that composes services, binds the UI shell, routes runtime surfaces, or assembles local-first + shared-mesh behavior belongs in `agentos-spine`.
+
+### 4. `workstation-contracts` is the lane and conformance gate
+
+Anything that defines execution-lane shape, validation, conformance, evidence collection, and build/release admissibility belongs in `workstation-contracts`.
+
+### 5. `socios` is opt-in automation only
+
+Anything involving community automation, CI/CD automation, catalog publication, signatures, or optional AI-assisted automation belongs in `socios` and must remain opt-in.
+
+---
+
+## Build and orchestration placement
+
+The upstream lane split should be treated as:
+
+- **Argo / Tekton**: orchestration and execution-lane control-plane tooling for GitOps, workflow execution, and pipeline admission.
+- **Foreman / Katello**: content, provisioning, build promotion, repository/content views, and image/package lifecycle management.
+
+These are complementary roles, not replacements for one another.
+
+### Practical interpretation
+
+- `workstation-contracts` should describe *what* a valid lane looks like.
+- Argo / Tekton should execute validated lanes.
+- Foreman / Katello should manage image/content promotion and provisioning inputs that validated lanes consume.
+- `socios` may automate portions of this stack, but only under Proof-of-Life + signed intent.
+
+---
+
+## Privacy and local-first stance
+
+The registry assumes the following operating posture:
+
+- local-first by default
+- shared mesh promotion only when human quorum and platform health gates pass
+- privacy-preserving analytics only when opt-in, with both k-anonymity and differential privacy controls
+- content-addressed and immutable history rather than destructive overwrite
+- proofs, provenance, and attestation always visible in viewer/search layers
+
+---
+
+## Follow-on contract work implied by this registry
+
+This document implies future additive contract work in `sourceos-spec` for at least:
+
+1. MICHAEL identity/attestation document(s)
+2. PRAXIS action/verb schemas
+3. ASHAMAAT receipt / validator / anchor schemas
+4. PHAROS/ARIADNE AsyncAPI channels + headers
+5. IANUS corridor/path/bridge policy shapes
+6. Codex manifest / edition / visibility contracts
+7. Kairos / Shiloh policy and gate objects
+8. ARGUS PHYLAX evidence / SLO / anomaly-attestation records
+
+---
+
+## Status
+
+This registry is a docs-first landing artifact. It is not yet normative over the existing schema catalog. It is intended to guide the next additive spec PRs.

+# ADR 9000: UMA Pistis ecosystem placement and lane split
+
+- Status: Accepted
+- Date: 2026-04-14
+
+## Context
+
+The SourceOS/SociOS repos already separate substrate, typed contracts, execution lanes, integration assembly, and opt-in automation. New local-first platform work introduced a human-readable naming layer (UMA Pistis, MICHAEL, PHAROS, PRAXIS, etc.) and an explicit requirement to preserve repo boundaries rather than collapse all work into one place.
+
+At the same time, the build/control stack needs a clear split:
+
+- Argo / Tekton for orchestration, pipeline execution, and GitOps-facing lane control
+- Foreman / Katello for provisioning, content, repositories, promotion, and image/package lifecycle management
+
+## Decision
+
+1. The named UMA Pistis concepts are documented in `docs/UMA_PISTIS_PANTHEON_REGISTRY.md` as the human-readable mapping layer.
+2. Machine-readable objects for those concepts must land first in `sourceos-spec` when they become normative contracts.
+3. Runtime/integration behavior belongs in `agentos-spine`; immutable Linux posture belongs in `source-os`; lane validation and conformance belong in `workstation-contracts`; optional automation belongs in `socios`.
+4. Argo / Tekton and Foreman / Katello are treated as complementary stack layers, not substitute choices.
+
+## Consequences
+
+### Positive
+
+- New platform vocabulary can be discussed and aligned upstream before full schema work lands.
+- Future contract additions have an explicit placement rule.
+- The build/content stack is described without confusing execution lanes with content promotion.
+
+### Negative
+
+- The registry adds one more docs layer that must be kept aligned with schemas.
+- Follow-on PRs are still required before these concepts become machine-enforced.
+
+## Follow-on work
+
+- Add MICHAEL, PRAXIS, ASHAMAAT, PHAROS/ARIADNE, IANUS, Codex, Kairos, and Shiloh contracts as additive schema/API changes.
+- Add workstation-contracts documentation clarifying Argo/Tekton lane execution versus Foreman/Katello content/provisioning.
+- Add agentos-spine docs explaining where CloudHaven / workspace composition belongs relative to these contracts.
