feat(PROMPT-MGMT-ARCH-WP-043) v1.0.0 — Prompt Management & Reporting App End-to-End Technical & Governance Architecture (2026-2030)

Adds the WP-043 reference for an AI prompt management & reporting application
that unifies advanced prompt engineering, AI safety governance, collaborative
refinement, variable linking, accessibility/onboarding, model registry binding,
RBAC for model operations, secure API key management, enhanced WORM audit
logging, distributed tracing for agent swarms, AI personas, prompt version
control, history & testing, template search, login UX improvements,
Markdown→HTML rendering with Tailwind, code syntax highlighting, signed PDF
export, and Firestore-backed report versioning.

Builds on WP-035..WP-042 lineage. Layered reference architecture (L0..L6):
identity & tenancy → edge → app API → model gateway → governance plane →
data plane → observability. Policy-as-code (OPA/Rego) with two-eyes/SoD;
CRDT (Yjs) co-editing; KMS-broker secret management with FIPS 140-3 root;
hash-chained Decision Envelopes anchored daily to Sentinel ICGC ledger;
OpenTelemetry GenAI semantic conventions for agent-swarm tracing;
WCAG 2.2 AA accessibility; passkey-first WebAuthn auth with step-up MFA.

Aligned with EU AI Act 2026 (Arts 9/10/13/14/50/53/55), NIST AI RMF 1.0,
ISO/IEC 42001/23894/27001/27701/5338, GDPR Arts 5/6/22/25/32/35,
WCAG 2.2 AA, SOC 2 Type II, OWASP LLM Top 10 (2025), FIPS 140-3,
OECD AI Principles.

Counts: 14 modules, 59 sections, 12 schemas, 16 code examples, 6 case studies,
22 supervisory KPIs, 9 RBAC roles, 6 data flows, 8 threats, 10 traceability
rows, 96 API routes (/api/prompt-mgmt-arch/*).

Sample KPIs: decision-traceability ≥ 99.95%; PII leakage ≤ 0.01%;
blocked-harm ≥ 99.5%; regression false-negative ≤ 0.5%; PDF export median
≤ 3s (p95 ≤ 8s); kill-switch ≤ 60s; MFA on sensitive scopes 100%;
faithfulness on golden RAG set ≥ 0.92; onboarding completion ≥ 80%.

Deliverables (in rag-agentic-dashboard/):
 - data/prompt-mgmt-arch.json (70.6 KB)
 - gen-prompt-mgmt-arch.py
 - gen-prompt-mgmt-arch-html.py
 - public/prompt-mgmt-arch.html (70.1 KB SPA dashboard, 71,761 bytes served)
 - server.js: 28 new /api/prompt-mgmt-arch/* route registrations

Validation: node -c server.js OK; PM2 rag-dash online; HTTP 200 on all
module roots (M1..M14), executive-summary, summary, counts, regimes,
personas, privacy, traceability, deployment, modules, kpis, rbac-roles,
data-flows, threats, schemas, code-examples, case-studies, plus all
sampled lookups (sections/M1-S1, personas/PERSONA-PE, kpis/KPI-01,
rbac-roles/ROLE-01, data-flows/DF-01, threats/TH-01,
schemas/promptTemplate, code-examples/CE-01, case-studies/CS-01);
10 negative-path checks return 404; dashboard HTML 71,761 bytes.
