# K-13 — DoD oracle layers (tight-loop → heavy)
# Category: KEY (Phase F)
# Kapitel: 10 – Definition of Done und autonome Loops
# Anker: Orakel-Härte × Frequenz; teure Checks nicht in jeden Turn
# Orientierung: 16:9 landscape
# Didaktik: Pyramide/Schichten — billig&häufig oben, teuer&selten unten; verhindert Over-Invest in Heavy-Oracles.
# Caption (DE): Orakel nach Härte × Frequenz: billige Checks in den Loop, Heavy selten.

# Complements: K-07 (autonomous DoD loop) — does NOT replace it

--- PROMPT START ---
Create a premium layered pyramid (or stepped horizontal bands) infographic, 16:9 landscape, for a professional practice book chapter on Definition of Done oracles for coding agents.

OUTPUT SPECS:
- Aspect ratio: exactly 16:9 landscape
- Clean flat-vector editorial with soft depth; print-ready; high grayscale contrast
- NOT a photo, NOT a CI vendor dashboard screenshot

TOPIC:
DoD quality depends on oracle hardness × frequency. Put cheap fast checks in the tight loop; keep expensive heavy oracles rare. Wrong placement burns time and context.

TITLE (exact):
DoD oracle layers
SUBTITLE (exact):
hardness × frequency — invest where it pays

COLOR / STYLE:
- Background off-white #F8FAFC
- Navy #0B1F33 structure; slate #334155 labels
- Top layer: sweet-spot green #16A34A (tight-loop)
- Upper-mid: teal #0D9488 (slice DoD)
- Lower-mid: soft blue #2563EB (pre-merge / CI)
- Base: amber #D97706 to muted slate (heavy / rare)
- Flat vector; soft shadows; generous margins

COMPOSITION — FOUR LAYERS, TOP = MOST FREQUENT / CHEAPEST:

Layer 1 (apex / top band) — green:
"Tight-loop"
chips: "typecheck" · "scoped unit" · "scope-diff"
note chip: "cheap · every turn"

Layer 2:
"Slice DoD + contracts"
chips: "acceptance checks" · "API contracts"
note: "per vertical slice"

Layer 3:
"Pre-merge / CI"
chips: "diff-coverage" · "secrets scan"
note: "before integrate"

Layer 4 (base / widest) — amber/slate:
"Heavy"
chips: "mutation" · "fuzz" · "full E2E" · "performance"
note: "expensive · rare"

SIDE ANNOTATIONS (two vertical axis hints, short):
- Left or right arrow up: "frequency ↑"
- Opposite or same side arrow down on cost: "cost / latency ↓ toward top"
Optional third arrow: "invest priority → tight-loop first"

TYPOGRAPHY:
- English only; short labels; no paragraphs
- Max ~12 primary labels; chips may be smaller
- Never render meta prompt text as labels

ALLOWED TEXT (whitelist priority):
- Title / subtitle
- Layer titles: Tight-loop · Slice DoD + contracts · Pre-merge / CI · Heavy
- Chips listed above
- Axis notes: frequency ↑ · cost / latency ↓ · cheap · every turn · expensive · rare · invest priority → tight-loop first

VISUAL RULES:
- Pyramid OR equal-width stacked bands with clear hierarchy top→bottom
- Top must feel fast/light; base must feel heavy/wide
- Do not put Heavy at the top
- Do not invent fake metric numbers or vendor CI product names

NEGATIVE:
- robots, logos, neon, watermarks, German body text, fake percent SLAs

FINAL SELF-CHECK:
Four layers in order Tight-loop → Slice DoD → Pre-merge/CI → Heavy. Frequency high at top; cost high at base.
--- PROMPT END ---

# Follow-up edit:
# Force layer order top→bottom. Keep Heavy as base only.
# Axis arrows: frequency up, cost down toward top.
# SVG if layer order or chip set collapses.
#
# QA-Note 2026-08-15: JPEG from SVG; cost high at Heavy base; invest → tight-loop.
