Reader Promise This release turns the repository from a pattern catalog into an online technical book for software engineers building agentic systems. It adds reader paths, logical chapter groups, diagrams, Mermaid/SVG visual coverage, production review artifacts, labs, capstones, Pagefind search, release evidence, and courtesy PDF/EPUB exports. Primary reader paths affected: - First-time path - Builder path - Lab path - Capstone path - Reference path - Publishing appendix Readers should be able to: - choose an agentic pattern by engineering concern; - understand state, policy, tools, approvals, traces, and evals; - run deterministic examples; - use labs and capstones as review material; - inspect release evidence before trusting the published book. 2.

Public GitHub Pages Evidence Public probe result on 2026-06-21: The public GitHub Pages site serves the current Astro book deployment from commit 4acc30b. The online reader, chapter routes, Pagefind assets, PDF, EPUB, templates, traces, and diagrams are reachable from the public URL. Observed URL results: - https://gturitto.github.io/Agentic-Systems-Patterns/ returned HTTP 200 and exposed the current online book homepage with 104 chapters. - https://gturitto.github.io/Agentic-Systems-Patterns/book/intro/ returned HTTP 200 and exposed the current Introduction chapter. - https://gturitto.github.io/Agentic-Systems-Patterns/book/publishing/how-to-read/ returned HTTP 200. - https://gturitto.github.io/Agentic-Systems-Patterns/book/hands-on-labs/ returned HTTP 200. - https://gturitto.github.io/Agentic-Systems-Patterns/book/capstone-projects/support-refund-agent/ returned HTTP 200. - https://gturitto.github.io/Agentic-Systems-Patterns/pagefind/pagefind.js returned HTTP 200 and served Pagefind 1.5.2. - https://gturitto.github.io/Agentic-Systems-Patterns/releases/Agentic-Systems-Patterns.pdf returned HTTP 200 with content-type application/pdf and content-length 6531709. - https://gturitto.github.io/Agentic-Systems-Patterns/releases/Agentic-Systems-Patterns.epub returned HTTP 200 with content-type application/epub+zip and content-length 1732089. - https://gturitto.github.io/Agentic-Systems-Patterns/capstone-assets/templates/lab-completion-worksheet.txt returned HTTP 200. - https://gturitto.github.io/Agentic-Systems-Patterns/capstone-assets/traces/support-refund-agent.trace.json returned HTTP 200. - https://gturitto.github.io/Agentic-Systems-Patterns/diagrams/agent-loop.svg returned HTTP 200. [x] Homepage loads with current online book shell. [x] Introduction loads. [x] How To Read This Book loads. [x] Sidebar navigation is present on public chapter pages. [x] Section pages load. [x] Search asset loads. [x] Search metadata and fallback data are present in the built pages. [x] Courtesy PDF downloads. [x] Courtesy EPUB downloads. [x] At least one worksheet downloads. [x] At least one diagram renders as an SVG asset. [x] At least one capstone trace artifact downloads. 6. Known Limitations - The draw.io CLI is not installed locally; committed SVG exports were validated instead. - Vite reported chunk-size warnings during book/site builds; builds completed and route/link checks passed. - Native framework examples are validation and comparison slices, not full framework tutorials. - Live model-provider paths require local credentials and are outside deterministic release verification. 7. Release Decision [x] Ready for public deployment verification. [x] Ship publicly after GitHub Pages evidence passes. [ ] Do not ship. Reason: The local release gate passed, the deployed site serves the current online reader, PDF, EPUB, search asset, templates, traces, and diagrams, and the book has concrete reader paths, labs, capstones, release checks, diagrams, and artifacts. Rollback action: Revert or redeploy the previous GitHub Pages artifact from the last known-good workflow run. Hold public announcement if any required URL, download, search index, or core reader path fails. Next editorial fixes: - Optional: capture fresh framework setup transcripts for launch appendix polish.
