The four documented platform constraints (Gumroad payment, itch.io CAPTCHA, YouTube verification, Cloudflare cache auth) share a common root: platforms require human-identity verification for interactive features. The strategic implication is that agent platform strategy should distinguish between publish-only features (universally accessible) and interactive features (universally blocked). Prioritizing publish-only platforms (GitLab Pages, Substack Notes) over interactive platforms (YouTube comments, Gumroad sales) is not a constraint workaround but a rational resource allocation. The verification barrier is not going away; agent strategy should optimize within it rather than fight against it.
