---

Note

Low Risk
Additive managed integration and config helpers with standard offline tests; no auth or provisioning behavior changes for existing providers beyond new registry dispatch.

Overview
Adds a WordPress.com Phase 1 catalog family for wordpress.com/site (wordpress-com provider, required plan, site_url output) with registry wiring, catalog gap test, and hermetic provision test; OUTPUT_FIELDS stay provisional until live discover.

Also extends stackless-provider-sdk with optional/required integer and boolean config readers for generated catalog adapters, documents catalog-first waves and exclusions in PROVIDER-WAVES.md / DECISIONS.md, and adds scripts/generate_catalog_integrations.py to scaffold remaining deployables (WordPress.com domain purchase remains excluded).

Codegen drops implemented registry rows

Medium Severity

The catalog generator’s IMPLEMENTED set omits wordpress.com/site even though this PR lands that adapter manually. The script rebuilds register_providers! from only hardcoded Clerk/Cloudflare rows plus newly generated services, so marking the service implemented later removes the wordpress-com registry row while providers/mod.rs is rewritten without wordpress_com, leaving stacks unable to resolve that provider.
