 **Goal:** Shrink the homepage's dark proof band to the five third-party Airworthiness rows, and add a bold "No runtime." band (copy left, two vertical flow diagrams right) between the architecture diagram and the Fork-us band, plus one FAQ entry.
 
-**Architecture:** Section 1 is a deletion: the two checklist columns and three self-reported rows leave `lib/preflight-checklist.ts`, `PreflightChecklist.tsx`, and `landing.css`, and the guards shrink with them. Section 2 is a new client-free server component `NoRuntimeBand.tsx` that reads every string from a new `NO_RUNTIME_BAND` object in `lib/positioning.ts`, draws the flows in plain HTML/CSS, and is pinned by a unit spec, the spine e2e, and a new measuring e2e. Section 3 adds one FAQ item.

Section 2 is a new `NoRuntimeBand.tsx` (`'use client'` only for the tracked link, like `OpenSourceStrip.tsx`) that reads every string from a new `NO_RUNTIME_BAND` object in `lib/positioning.ts`, draws the flows in plain HTML/CSS, and is pinned by a unit spec, the spine e2e, and a new measuring e2e. Section 3 adds one FAQ item.
 
 **Tech Stack:** Next.js app in `apps/website` (React server components, `'use client'` only where hooks are used), Vitest + Testing Library (jsdom), Playwright e2e, plain CSS in `apps/website/src/styles/landing.css`, Nx targets.

 # The trust band shrinks, and a No-runtime band lands after the architecture diagram
 
 **Date:** 2026-09-11
-**Status:** Approved in conversation, awaiting written review
+**Status:** Implemented on `blove/homepage-trust-no-runtime` (§2.2 figures and §3.1/§5 runway decision record what shipped)
 **Branch:** `blove/homepage-trust-no-runtime`
 **Supersedes:** the two-column checklist in `2026-09-08-preflight-checklist-design.md` §2 (the Airworthiness block survives; the Threadplane and Yours columns do not)
