VALIDATION — 7-day smoke test, < $50

Prove there is paid demand before writing the full playbook. Total hard cost: €0–20 (domain optional; everything else is free tiers + fees only on actual sales).

The test

Sell the thing before it fully exists — with an honest “ships in 14 days” pre-order, plus a free lead magnet to measure top-of-funnel.

Setup (Day 1, ~2h of Joshua’s time; assets already built overnight)

Publish index.html to a Cloudflare Pages URL (free) — e.g. pflegegrad.unicorn.land or a Pages subdomain. No new domain needed (€0).
Gumroad product: pre-order at €69 launch price, “delivers 14 days after purchase, full refund any time before delivery.” Gumroad free; fees only on sales.
Free lead magnet on the same page: “5 Mistakes English-Speaking Parents Make at the MDK Assessment” — 1-page PDF, delivered via Gumroad €0 product (doubles as email capture).
Calendly link for the €150 call, live immediately (the call needs no product build — his knowledge exists today).

Distribution (Days 2–6, story-first, zero ad spend)

Day 0 (morning of Day 1): request to JOIN all Facebook groups on the README channel target list — approval lag is 1–3 days.
Day 2: Personal win story in the Berlin groups from the README channel list (#1–4) + 1 special-needs parent group (#5). No link in post; “DM me / link in comments” per group rules.
Day 3: Reddit — r/germany weekly question thread only (the sub removes self-promo; AMAs need prior mod approval). Fallback if even a story post is disallowed: comment-only participation per the README’s Reddit fallback (answer Pflegegrad/MDK/Widerspruch questions, link only on DM request).
Day 4: 3 warm contacts at international schools / parent networks — forwardable email (copy in README).
Day 5: Munich/Frankfurt/Hamburg expat groups (README channel list #6–7) + 1-2 diagnosis-specific English groups (FASD, autism).
Day 6: Follow-ups, answer every comment/DM.

Optional accelerant if organic stalls: €20 boosted post to expat-parents-in-Germany audience. Keeps total < $50.

Success thresholds (Day 7 readout)

Signal	Kill	Iterate	Green
Landing-page visits	< 100	100–300	> 300
Lead-magnet downloads / emails	< 15	15–40	> 40
Pre-orders (€69)	0	1–2	≥ 3
Call bookings (€150)	0	—	≥ 1
DMs asking case-specific questions	< 3	3–10	> 10

GREEN (≥3 pre-orders or ≥1 call + >40 emails): build the full playbook in week 2; the month-one plan in SPEC.md is live.
ITERATE (1–2 pre-orders, decent traffic): demand exists but price or promise is off. Test €49, or pivot the lead offer to the call (urgency buyers first).
KILL (0 pre-orders and <15 emails after 8+ group posts): refund anything, keep the lead magnet up as goodwill, archive. Cost of learning: ~€0 and ~6 hours.

Why this test is the cheapest true signal

Pre-orders are money, not opinions. Facebook likes and “this is so needed!” comments don’t count in any threshold above.
The call requires zero build — it can generate real revenue during the test itself.
Everything decays gracefully: if killed, the only artifacts are a free PDF that helps people and a landing page that cost nothing.

Rechtsberatung guardrail during the test

Every asset carries the disclaimer (drafted in README). In DMs, Joshua shares his experience and points to the resources; he does not tell anyone what to file. If someone needs actual legal advice, refer to VdK / SoVD (membership ~€6-8/mo includes Widerspruch representation) — mentioning this in the playbook is also a trust-builder.
