Supabase RLS design template pack
¥9,800 (tax incl.)
A copy-paste template pack that keeps your Supabase Row Level Security from shipping in the "authenticated, but rows unscoped" state. Beyond the basics my free RLS policy generator covers, it bundles what real projects need: multi-tenant design, role-based (RBAC) policies, the service_role boundary, WITH CHECK/USING pitfalls, and pgTAP test scaffolds — with usage commentary.
Format: メール納品（Markdown・コピペ可能なSQLテンプレート付き）

Product FAQ
- How is this different from the free RLS policy generator?
- The free tool generates the single-table basics (owner scoping etc.). This pack covers what comes next — multi-tenant design, RBAC, the service_role boundary, WITH CHECK/USING pitfalls, and pgTAP tests — as a full set with usage commentary.
- How is it delivered after purchase?
- Within a few minutes of completing Stripe checkout, the full content (Markdown with paste-ready SQL) is emailed to the address you registered. Contact me if it doesn't arrive.
- Is there an English edition?
- The product description is available in English, but the content itself is Japanese (as of v1). The SQL templates are usable as-is.
An execution manual: what to check, how, and what counts as a pass
Web app security audit checklist Pro
¥6,800 (tax incl.)

Format: メール納品（Markdown・監査手順＋合格基準つきチェックリスト）
What's inside
- 1. Authorization & IDOR (vertical & horizontal privilege escalation)
- 2. Authentication & session management
- 3. Input validation & injection

Pre-engagement checklist Pro: estimates, contracts, and acceptance
¥3,000 (tax incl.)
The practical extension of the free "20 questions to gauge a vendor." It turns the stages beyond technical vetting into checklists: how to read an estimate (line-item red flags), contract clauses (ukeoi/jun-inin, IP, non-conformity liability), avoiding black-box delivery, acceptance testing, and operational handover.
