Validation: arch-generic-checkout migration (#254)

Ticket

forgejo_admin/pal-e-api#254 — Migrate arch-generic-checkout to template-conformant architecture note. Board item #968 on board-pal-e-docs.

Environment

pal-e-docs production API (https://pal-e-docs.tail5b443a.ts.net). Content task — no deployment, no pod restart, no migration. Changes applied via mcp__pal-e-docs__update_note.

Checks

PASS — get_note_toc(slug="arch-generic-checkout") returns all 4 required template-architecture headings in order: Diagram, Components, Key Decisions, Related
PASS — Diagram section contains a sequenceDiagram mermaid fence (correct facet keyword for a data-flow note)
PASS — Components table has 6 rows (Parent, Email, westside-app, basketball-api, PostgreSQL, Stripe) with Component | Purpose | Notes columns
PASS — Key Decisions has 6 WHY-focused bullets covering token auth, DB-driven products, JSONB fields, Stripe Checkout, opt-out pattern, category filtering
PASS — Original prose preserved: Database Schema tables, API Endpoints table, Adding a New Product Type guide all retained as additional sections between Key Decisions and Related (allowed by template)
PASS — get_note_links(slug="arch-generic-checkout") returned zero inbound refs pre-migration — no link breakage risk. Slug unchanged.
PASS — Title updated to "Data Flow: Generic Checkout System" matching template naming convention for dataflow facet

Verdict

PASS — all 7 checks pass. The note is now template-conformant per template-architecture. The grandfather entry in check-note-template.sh can be removed in a separate follow-up PR (already scoped in the ticket's AC).

Discovered Issues

Follow-up (already scoped): Remove arch-generic-checkout from the grandfather list in hooks/check-note-template.sh (claude-custom). This was AC item in the original ticket and should be a small follow-up PR once the hook from PR #240 is validated.
