📝 Walkthrough

Walkthrough

This PR comprehensively restructures the AI Reliability Engineering documentation by expanding from a four-pillar to a five-pillar framework, introducing AIRE principles, and adding extensive supporting documentation including getting-started guides, metrics framework, glossary, and detailed pillar implementations. Configuration updates align the site structure with the new content organization.

Changes

Cohort / File(s)	Summary
Core Documentation & Configuration README.md, mkdocs.yml	README rewritten with updated goals, tone shift from theoretical to practical, new AIRE Principles section, five-pillar framework introduction, and sponsor contact update. mkdocs.yml refactored to reflect new site structure, renamed to "AIRE Standards," updated nav to Home/Pillars/Appendix hierarchy, and added markdown extensions (highlight, tabbed, superfences/mermaid).
Foundation & Principles docs/index.md, docs/principles.md	index.md introduces AIRE overview with five core pillars, principles, and getting-started guidance. principles.md details five guiding principles (Embrace Non-Determinism, Reliability as Feature, Measure/Don't Assume, Fail Gracefully, Humans as Fallback) with examples and application patterns.
Pillar Documentation docs/pillars/resilient-architecture.md, docs/pillars/cognitive-reliability.md, docs/pillars/quality-lifecycle.md, docs/pillars/security.md, docs/pillars/operational-excellence.md	Five new pillar documents detailing: (1) resilience patterns (Reliability Stack, scaling, state management, circuit breakers, fallbacks); (2) cognitive reliability (self-reflection, structured outputs, HITL, drift detection); (3) quality lifecycle (evaluation-driven deployments, golden datasets, testing, feedback loops); (4) security (JIT privilege access, guardrails, prompt injection defenses, privacy); (5) operational excellence (performance targets, quality budgets, team structure, autonomy progression model).
Getting Started & Frameworks docs/getting-started.md, docs/appendix/metrics-framework.md	getting-started.md provides phased adoption roadmap (Phase 1–5), maturity assessment, implementation priorities, success metrics, and common challenges. metrics-framework.md establishes three-tier metric structure (Business, System, Component) with specific targets, measurement approaches, and thresholds across availability, latency, quality, safety, efficiency, and drift detection.
Reference & Glossary docs/appendix/glossary.md	Comprehensive glossary of AIRE terminology (A–S) defining key concepts referenced throughout the framework; licensed under CC BY 4.0.

Poem

🐰 Five pillars now, not four, hooray!
From standards cold to guidance bright—
Non-determinism's here to stay,
With metrics, guards, and team delight.
A framework built for agents' flight! 🚀
