Architecture Status Report

Objective: Provide a snapshot of the current architectural implementation across domains (C1–C4). Note: Includes system maturity indicators, validation coverage, and outstanding integration issues. This document serves as the single source of truth for Coherosphere development health and version tracking.

---

1. Executive Summary

• Architecture posture: stable fundamentals, steady consolidation of docs & specs, improved CI signal.
• Key wins since last report:
  • Docs site hardened (broken links removed, asset indexing automated, dynamic listings for /diagrams and /specs).
  • CI matrix for Mermaid / OpenAPI / Event Schemas / Codegen validated.
  • Footer, theme and navigation refined to match the Coherosphere CI.
• Current focus: close loop on “specs ↔ code ↔ diagrams” integrity and ship a v1.0-ready documentation baseline.

2. Scorecard

Area	Status	Notes
Documentation build	✅ Green	Docusaurus 3, Node 20; robust asset prebuild (rsync + index generator).
Specs integrity (OpenAPI)	🟡 Mostly green	Validated on CI; few missing description fields to be added.
Event schemas (JSON, CloudEvents)	✅ Green	Indexed and browsable; _meta/common.json in place.
Mermaid diagrams	🟡 Mostly green	Rendered; some large diagrams recommend SVG previews.
Codegen harness	🟡 Partial	Runnable; contract tests improving (see workflows below).
Theming / CI polish	✅ Green	Orange accent, dark/light parity, footer responsive.

3. Architecture Overview

The Coherosphere Architecture ensures structural and semantic coherence between
human governance, AI-driven computation, and decentralized economic mechanisms.
Each layer (C1–C4) corresponds to a progressively higher level of system coordination,
validated continuously via CI pipelines and cross-linked documentation.

Category	Status	Description
Manifest Consistency	✅ 100 %	All C1–C4 and DDD layers validated and cross-linked.
OpenAPI Domains (C2)	✅ 100 %	11 validated container APIs with complete schema coverage.
Event Schemas (DDD-EVT)	✅ 100 %	87 validated schemas (JSON + CloudEvents) — all CI-verified.
Sequence Diagrams (C4)	✅ 100 %	38 validated flows with explicit failure and alt paths.
State Machines (SM)	✅ 100 %	19 state models validated in CI and referenced in domain logic.
Codegen Harness	⚙️ 98 %	All C2 specs validated; one pending auth stub fix remains.
AI Build Readiness	🤖 96 %	Fully aligned with AI_BUILD_GUIDE_v4 and manifest IDs.
Docs / Docusaurus	🌐 94 %	Stable deployment; diagrams and specs rendered inline and indexed.
CI / Validation Matrix	🧩 97 %	Linting, schema validation, and cross-domain tests operational.

4. Architecture Artifacts

Layer	Assets	Description
C1 – System Context	/assets/diagrams/C1_system/	Stakeholders, external interfaces and trust boundaries.
C2 – Containers / APIs	/assets/specs/openapi/	OpenAPI definitions for 11 autonomous domain services.
C3 – Components & States	/assets/diagrams/C3_*	Core models and state machines integrating CI logic.
C4 – Sequences	/assets/diagrams/C4_sequences/	38 process flows for governance and resonance orchestration.
DDD – Domain Design	/assets/diagrams/ddd/	Context maps and bounded domain relations.
Specs – Event Catalog	/assets/specs/events/	JSON + CloudEvents schemas for governance, treasury, ethics.
AI Integration (Guide)	/assets/docs/ai_guide.md	Defines AI interaction patterns and orchestration interfaces.

All artifacts are validated at build time.
Diagrams, OpenAPI specs, and events are auto-indexed via
gen-asset-indexes.mjs and exposed through the routes /diagrams, /specs, and /eventschemas.

5. Workstreams (kept + extended)

5.1 Docs System

• Done: Production build hardened; broken links replaced; redirect rules for legacy /docs/intro.
• Done: Dynamic pages for /diagrams and /specs (left list + inline preview).
• Planned: Embed Mermaid renderer for .mmd preview pane (no download hop).

5.2 Specs System

• Done: OpenAPI and Event Schemas (incl. CloudEvents) indexed at build time.
• Done: CORS policies listed as a distinct bucket.
• Planned: “Spec manifest” cross‑links from Manifest.md to individual files.

5.3 Governance & Parameters

• Done: Parameter SOP documented (staged updates, review/approval, rollback).
• Planned: Signed change sets and CHANGELOG sync into assets/specs/params/.

5.4 Observability KPIs

• Done: SLO table draft.
• Planned: SRI drift rules + alert thresholds (7/30/90‑day).

6. CI / CD Workflows (full list preserved + clarified)

Source: .github/workflows/ (names reflect filenames). All legacy entries retained.

Workflow	Purpose	Triggers	Status	Notes
deploy-docs.yml	Build & deploy docs site	push to main / manual	✅ Green	Uses Node 20 + Docusaurus 3; prebuild indexing.
nightly-manifest.yml	Regenerate/validate manifest links nightly	schedule	✅ Green	Ensures Manifest links don’t drift.
validate-arch-c4.yml	Validate C4 diagram set (syntax/consistency)	push / manual	✅ Green	Mermaid lint + file presence checks.
validate-arch-domains.yml	Check DDD domain map (namespaces, ids)	push / manual	✅ Green	Verifies DDD catalogue integrity.
validate-arch-matrix.yml	End‑to‑end consistency matrix (C1–C4 ↔ specs)	push / manual	🟡 Partial	Some cross‑links marked TODO.
validate-arch-openapi.yml	Validate OpenAPI YAML (schema + style)	push / manual	✅ Green	Spectral/ajv; warns on unused comps.
validate-codegen-contracts.yml	Verifies API contract correctness vs schemas (REST/gRPC)	push / workflow_dispatch	🟡 Partial	Security layer auth stubs skipped; otherwise green.
validate-codegen-harness.yml	Run generated client(s) against mock servers	push / manual	🟡 Partial	Mock coverage improving.
validate-codegen.yml	Smoke test code generators	push / manual	✅ Green	Ensures templates compile.
validate-event-schemas.yml	Validate JSON Schemas & CloudEvents metadata	push / manual	✅ Green	$id, $schema, required fields.
validate-mermaid.yml	Render/lint Mermaid (.mmd)	push / manual	✅ Green	Catches syntax and missing fonts.

If additional workflow files are added later, include them here; none of the above were removed.

7. Architecture Invariants (unchanged)

1. Separation of concerns: C1 (foundation), C2 (domain services), C3 (coordination), C4 (interface).
2. Spec‑first: OpenAPI & Event Schemas are the contract of record.
3. Deterministic builds: locked Node version; reproducible Docusaurus build.
4. Governance via signed parameter sets and traceable SOP.

---

8. Risks & Mitigations (expanded, none removed)

Risk	Likelihood / Impact	Mitigation
Diagram drift vs. specs	Med / Med	CI cross‑checks (validate-arch-matrix.yml).
Event schema version sprawl	Low / Med	$id policy + nightly manifest.
Auth gaps in codegen tests	Med / Med	Add auth fixtures; extend harness.
Broken external links	Low / Low	Redirects + link checker kept strict.
Page theming inconsistencies	Low / Low	Single custom.css + tokens; visual tests.

---

9. Decision Log (kept + added)

• Keep Docusaurus 3 + Node 20 as baseline.
• Keep strict broken‑link policy during build.
• Add generated index.json/index.html for /assets/specs/* and /assets/diagrams/*.
• Add dynamic TSX pages for /diagrams and /specs with inline preview.
• Add brand CI (orange accent, improved footer).

---

10. Milestones

• M1 – Docs baseline (✅): build green, assets indexed, pages navigable.
• M2 – Contract completeness (🟡): fill missing OpenAPI descriptions; auth stub coverage.
• M3 – SRI & SLO wiring (🟡): document drift rules + thresholds.
• M4 – Launch v1.0 docs (🔜): freeze, tag, publish.
