Create a central radial overview diagram, 16:9 landscape, for a professional practice book about coding-agent knowledge management.

TOPIC: Knowledge layer for coding agents — agent in the center, memory tiers and external knowledge around it, with select and write-back flows.

GLOBAL STYLE:
- clean circular / radial layout; flat design; muted professional colors
- navy (#0B1F33), teal (#0D9488), soft blue, green, amber, violet accents; off-white background
- minimal English labels; high readability; print grayscale-safe
- no brand logos; no robot mascots; no neon

QUALITY GUARDRAILS:
- every visible word correctly spelled English; max ~12 short labels total
- generic coding agent icon only (abstract harness/node), no vendor packaging
- no fake product UI screenshots

Title text exactly: "Knowledge layer for coding agents"
Subtitle: "outside the window · on demand"

CENTER:
- abstract geometric "coding agent" node only — NO robot, NO astronaut, NO face, NO mascot
- subtitle under node exactly: "LLM and harness" (correct spelling; never "anl")

AROUND CENTER (four connected memory cards / arcs) — labels EXACTLY:
1. Working — "context now"
2. Episodic — "Handoff · Progress"  (never put Skills/DoD on Episodic)
3. Semantic — "AGENTS.md · facts"
4. Procedural — "Skills · DoD"

PLUS one external card slightly outside the ring:
- "External KB" (docs / wiki / MCP resources)

FLOWS:
- at most two teal arrows labeled "Select" (inward)
- at most two navy arrows labeled "Write-back" (outward)
- never more than four flow arrows total

BOTTOM STRIP:
"not a product · a discipline for durable knowledge"

MOOD: system map, calm, book-quality editorial.
ASPECT: 16:9.
NEGATIVE: no neon, no mascots, no watermarks, no vendor logos, no vector-DB marketing claims, no German labels.
--- PROMPT END ---

# Follow-up edit:
# Keep agent center, four tiers, external KB.
# Select arrows ONLY inward (External KB → agent, Semantic → agent).
# Write-back arrows ONLY outward (agent → Episodic, agent → Semantic).
# Never point Select at External KB.
