13.1 Platform spec home
Start at /platform-spec/—domains, areas, features, and reader chrome.
Platform spec home
Open /platform-spec/. That is the normative front door—no version prefix in the URL, Git as the axis (Release policy).
Use the home page to select the domain that owns a question, not to infer a rule from a tile title. Each domain leads to areas and feature hubs where the governing material is linked.

Reader chrome
Section titled “Reader chrome”Platform-spec pages use dedicated reader UI (tabs, ADRs, architecture graphs)—not the book’s chapter rail. Expect:
- Current document / Articles / ADRs / Architecture tabs on feature hubs

Book vs spec
Section titled “Book vs spec”| Need | Go to |
|---|---|
| Tutorial voice, workflows | /book/ |
| Enforceable contracts | /platform-spec/ |
| CLI flag lists | /book/reference/cli/ |
When a page is marked Proposed, treat it as a design or work-in-progress signal rather than silently relying on it as a stable guarantee. The specification authority guidance explains how authority and maturity are presented.
