 *AI-generated and human-written software architecture MUST follow secure-architecture principles. Authoritative rules: `constitution.md`, Principle XIII. Core principles: trust boundaries (validate all input at system boundaries), defense in depth (at least two independent security layers), least privilege (minimum required permissions), fail-safe defaults (deny by default), attack surface reduction (disable unused features), separation of concerns (auth/logging/validation as cross-cutting concerns), secure configuration (secrets in secret stores, never in code or Git), supply-chain security (verified registries, lock files, no known-vulnerable dependencies). Principles XII + XIII together form the complete secure-development approach: XII = tactical code-level security, XIII = strategic architecture-level security. Changes require a joint update across `constitution.md`, `.specify/memory/constitution.md`, and all four agent guidance files.*

+### XX. General iSAQB / arc42 Architecture Governance
+
+Software architecture MUST be treated as explicit design evidence when a
+change affects structure, interfaces, quality attributes, runtime behavior,
+deployment, or long-term maintainability. Security-specific architecture stays
+under Principle XIII; this principle covers general architecture reasoning.
+
+Mandatory rules:
+- Architecture work SHOULD follow iSAQB/CPSA-F method discipline and use
+  lightweight arc42-compatible documentation where useful.
+- Architecturally significant decisions MUST be documented as ADRs or
+  architecture decision records.
+- Quality attributes MUST be expressed as concrete scenarios with stimulus,
+  environment, response, and measurable response criteria. Generic words such
+  as "fast", "maintainable", or "scalable" are insufficient on their own.
+- System context, building blocks, runtime behavior, and deployment constraints
+  MUST be documented when they materially affect the design or future change
+  decisions.
+- Architecture risks and technical debt MUST be recorded with owner, impact,
+  mitigation, and review trigger when they affect delivery or operation.
+- Architecture documentation MUST remain proportional: enough to support
+  review, onboarding, maintenance, and later change decisions without turning
+  every small implementation detail into a formal architecture artefact.
+
+Evidence defaults:
+- General architecture evidence lives in `docs/architecture/`.
+- ADRs for general architecture default to `docs/architecture/adr/`.
+- Use the templates `architecture-vision-template.md`,
+  `context-view-template.md`, `building-block-view-template.md`,
+  `runtime-view-template.md`, `deployment-view-template.md`,
+  `architecture-decision-template.md`, `architecture-risks-template.md`, and
+  `quality-scenarios-template.md` when the corresponding artefact applies.
+- Security architecture evidence remains in `docs/security/`; if a decision is
+  both general and security-relevant, cross-link the records instead of
+  duplicating divergent content.
+
+**Rationale**: iSAQB and arc42 provide a lightweight, reviewable way to keep
+architecture decisions visible. Making general architecture evidence explicit
+prevents structural drift while leaving security-specific controls in the
+dedicated secure-architecture principles.
