Missing drops (cron failures / intentional skips)

MUGEN ideally drops 1 design per hour. Some hours skipped due to cron failure or deliberate "negative space" per Vision §14. Not hidden — published as-is.

Measurement: direct aggregation of our own funnel_events table (event='pageview'). Pageviews fire via enabler-analytics.fly.dev/t.js — our self-hosted endpoint. No Google Analytics, no Segment, no third-party trackers.

Methodology

real.revenue_jpy: SUM of Stripe live sessions (cs_live_*). Test sessions excluded.
external: real minus yuki's dogfooding (yuki@hamada.tokyo / mail@yukihamada.jp).
approx_mrr: paid subscriber count × monthly price. Annual plans converted to monthly equivalent.
designs_generated: total rows across products + you_designs.

Sample query (revenue):
SELECT COALESCE(SUM(amount_total),0) FROM stripe_sessions
WHERE id LIKE 'cs_live_%' AND payment_status='paid';

Domain continuity (Constitution §22)

MU has committed to keeping wearmu.com registered through at least 2126. Every T-shirt sold has a neck-back chronicle QR that resolves here — if the domain lapses, every shirt loses its trail. A daily agent polls VeriSign RDAP, persists the expiry below, and alerts Telegram at 90/60/30/7 days remaining.

What is MU?

MU is a brand where Hokkaido's weather designs the clothes. Every hour Gemini Pro generates one new T-shirt concept; the temperature decides today's edition size; Printful prints it; Stripe charges it; carriers ship it.

To be precise about the "0 humans" claim: yuki is one human — the maintainer / operator who pushes code, holds the Stripe key, and answers customer email. What the 28 agents do without humans: design, copy, pricing, scheduling, drops, blog, X posts, fulfillment hand-off. The brand-operations chain is unmanned. The repo isn't.

It's not that we have no revenue — it's that whatever revenue we have is published here, unedited. That's MU. The 4-line Vision + 20 operational principles live at /constitution.

Product spec (what you're buying)

The T-shirt itself, not the AI behind it.

Open-source protocol

MU is a brand and a protocol. The full stack — Rust + libsql + Gemini + Stripe + Printful — is published unedited, under MIT. Fork it; spin up your own brand using your own city's weather.

Sizestore/src/main.rs ≈ 30,000 LOC Rust + Python image helpers
AI — copy / agentsGemini 2.5 Pro + Flash (classify)
AI — image generationGemini 3 Pro Image
Fulfillment / paymentsPrintful + Stripe

Runs as 1 Fly.io process hosting 28 in-process agents (tokio-scheduled, 60s tick). Monthly operating cost: ~¥8,600/mo (~$57/mo) — Fly compute + Gemini API + Stripe fees. Honest setup time: ~1h end-to-end if Fly + Stripe + Gemini accounts already exist. README.
