Cloudflare's Workers AI FLUX.1 schnell content filter sometimes rejects peptide-comic prompts as NSFW (HTTP 400, errors[].code === 3030). On 2026-04-20 this produced a silent publish-without-featured-image for post #650 ("Semaglutide vs Tirzepatide") — the LLM-rewritten scene tripped the filter and we had no recovery path. New behaviour: on a 3030 response, the Cloudflare provider throws a typed PRAutoBlogger_Image_NSFW_Blocked exception. The batch wrapper catches it and tags the per-slot result with `error_type: nsfw_blocked`. Image_Pipeline hands the results to a new PRAutoBlogger_Image_NSFW_Retry helper, which reruns the blocked slot once with a sanitized fallback prompt (title + style suffix, no LLM rewrite). On success the retry result replaces the error entry; on a second block, a WARNING is logged and the pipeline publishes without that image — same terminal behaviour we had before, just explicit. Files: - New providers/class-image-nsfw-blocked.php — typed exception. - providers/class-cloudflare-image-support.php — is_nsfw_error() + throw_if_nsfw() helpers. - providers/class-cloudflare-image-provider.php — calls throw_if_nsfw inside the 4xx branch; batch catches the typed exception and marks the result with error_type. - core/class-image-prompt-builder.php — new public build_fallback_prompt shim so the retry layer can reach the rule-based fallback without going through the LLM path. - New core/class-image-nsfw-retry.php — single-shot retry helper. - core/class-image-pipeline.php — invokes the retry between batch completion and per-slot processing. - admin/class-settings-fields-extended.php — new toggle `prautoblogger_image_nsfw_retry` (default on) in the Images section. Tests: - CloudflareImageProviderTest — 3030 response throws NSFW exception; batch tags the per-slot result with `error_type: nsfw_blocked`. - ImagePipelineTest — retry succeeds when provider returns a good result on the second call; retry is skipped when the setting is off. Cost impact: worst-case an extra Cloudflare call per NSFW-blocked slot (~$0.000834). Current incidence ~2% of generations; ~+$0.00002 per generation amortized. Immaterial. Uninstall: new option covered by the existing prautoblogger_% LIKE sweep in uninstall.php. Part of the v0.8.0 image bundle (issues from thread image-mime-bug).
