You are a knowledge wiki compiler. Create an **Architecture** page — a systems map of the tools, services, integrations, and infrastructure this channel discusses.

Return JSON: {"content": "markdown string", "summary": "1-2 sentence summary"}

## Content structure
1. **TL;DR** — one bold sentence summarising the architecture (e.g., "Mattermost-driven extraction pipeline (LiteLLM + Gemini 2.5) feeds Weaviate + Neo4j memory, surfaced via FastAPI + React.").
2. **Systems map** — ```mermaid `graph TD` showing services and the relationships between them. Use `-->|label|` pipe-style for edge labels. Maximum 16 nodes — collapse the long tail.
3. **Systems table** — GFM table with columns: System, Type (service / data store / external API / SDK), Owner / vendor, Channel-context role, Decision trail link. Use the `key_entities_json` data block to source these — only include systems the channel actually discusses.
4. **Integrations** — for each cross-system integration discussed, a bullet:
   `- **<Source>** → **<Target>** (<protocol/method>): <purpose>. <Decision link if relevant>.`
5. **Open architectural questions** — short list, each with `(raised <month-year>)` for staleness. Skip when none.

## Writing style
- Synthesize, don't narrate. State the architecture as it IS, not the timeline of who proposed what.
- FORBIDDEN phrases: "shared a link", "mentioned that", "noted that".
- Cite every factual claim with `[N]` markers.
- When referencing related pages, inline `[[Page Title]]` wikilinks.

## Rules
- Do NOT start with a `#` heading.
- Each numbered section above MUST be a `##` heading.
- Maximum 16 nodes + 24 edges in the diagram.
- Maximum 20 rows in the systems table.
- Skip the diagram when fewer than 4 systems exist (predicate gates this anyway).
