Phase 7 (AUD-149), cheapest first. - internal/brand: vendored Simple Icons path data (CC0) for 50 marks, looked up by the technology label the content already uses. Inline SVG, 16 px, currentColor, no request and no font. tools/gen_brand_icons.sh regenerates it. - Six hand-drawn area icons replace the two-letter badges in the nav and on the landing cards; the evidence index gets a seventh. - TechChips renders a mark where one exists and plain text where one does not, so a missing icon reads as a decision rather than a broken image. - Client wall: 45 names as one typeface, one size, one grid of equal tiles, and the reason for no logo collage written on the page. No mark invented. - Two diagrams, authored in-repo: homelab topology (platform-network.md) and the RAG pipeline (ai-rag-corpus.md), each referenced from the page it explains. - Content images now carry intrinsic width/height, loading="lazy" and decoding="async" at render time; a site test fails the build if an image ships without them. - Topbar is two rows at desktop: the area names plus marks no longer overlap the search form (Lighthouse target-size was failing at 1440 px). - Favicon, so the browser stops requesting a missing /favicon.ico. Satisfies: logos on every area page, area icons in nav and cards, two diagrams referenced from their pages, images sized and lazy, Lighthouse >= 95 held.

Ingest and index are live; the diagram below shows both sides, and the query path is labelled as the design it is until Phase 5 ships.
What the artefact is
The ingest and query path: documents are chunked and tagged with metadata at ingest, stored in Qdrant, and filtered on that metadata before a similarity search runs. The LangGraph graph has four nodes; the fourth decides whether the answer can be given from what was retrieved.
What it proves
Retrieval designed around payload filtering and a hard stop, plus the reasoning for moving off ChromaDB — heavier footprint and weaker filtering — recorded as a decision rather than a migration.
The pipeline
The separating line is the design decision: metadata is written at ingest, so the query can filter by area, level and source before it pays for a similarity search. The fourth node is the hard stop — an answer that cannot be supported by what was retrieved is refused rather than improvised.
When it is delivered
Ingest is delivered and measured (this site's own corpus, Phase 4). The query path is delivered in Phase 5; the streaming console is the visitor-facing half of it.
