cf-removal: bump 0.9.0 -> 0.10.0 + update docs
- prautoblogger.php: plugin header Version + PRAUTOBLOGGER_VERSION - CHANGELOG.md: Removed/Changed/Note/Cost impact/Migration sections - ARCHITECTURE.md: - drop 4 CF provider files from the file tree - drop 2 CF credential options from the wp_options table - drop CF Workers AI row from the External API Integrations table - flip Phase 3 placeholder from CF Workers AI registry to Runware - supersede ADR #16 with a one-line history note pointing at v0.10.0 - update ADR #17 tail to mention the removal readme.txt stable tag is stale (0.2.2) and clearly not maintained inline with real releases — leaving alone in this PR; fix belongs in a dedicated release-process cleanup.

### #17: Runware as default image backend (v0.9.0, Apr 2026)
|
||||
|
||||
After a comic-style A/B round in Apr 2026, FLUX.1 schnell via Runware was chosen as the default image backend. Cost is ~$0.0006/image vs ~$0.039/image for Gemini 2.5 Flash Image via OpenRouter (≈65× cheaper), and the looser schnell fidelity reads as editorial-cartoon style — a feature, not a bug, for our single-panel comic aesthetic. FLUX.1 dev (~$0.02/image, 28 steps) remains available as an opt-in for higher-fidelity runs. The Runware layer mirrors the OpenRouter split (interface + provider + support + pricing + batch), all under the 300-line cap. The batch class dispatches `imageInference` POSTs via `curl_multi_init/exec/select` — wall-clock time for the A/B pair drops to ≈ the slowest single image. A v0.9.0 one-time migration (`prautoblogger_migrated_default_image_v090`) flips sites still on the legacy default; explicit user selections are preserved. Cloudflare Workers AI remains as a legacy fallback in the registry.

|
||||
|
||||
### #16: Image generation via Cloudflare Workers AI (FLUX.1) — SUPERSEDED v0.10.0
|
||||
Kept here for history. Until v0.8.2 the default image backend was FLUX.1 schnell on Cloudflare Workers AI, routed via the Cloudflare AI Gateway for caching + unified telemetry. In v0.9.0 (2026-04-21) Runware FLUX.1 schnell became the default (65× cheaper, see ADR #17). In v0.10.0 (2026-04-21) the Cloudflare Workers AI provider was removed entirely — classes, settings, tests, and registry entries are gone; any CF user is migrated to `runware:100@1` on upgrade via `PRAutoBlogger_Migrate_Remove_Cloudflare_V0100::run()`. The Cloudflare AI Gateway in front of OpenRouter (ADR #15) is unaffected — it is a distinct integration.
|
||||
|
||||
### #16: Image generation via Cloudflare Workers AI (FLUX.1), via AI Gateway (v0.8.2+)
|
||||
The image-generation layer uses FLUX.1 [schnell] on Cloudflare Workers AI as its default model, chosen for its ~$0.0011/MP cost and 2–3 sec latency. FLUX.1 [dev] is a ~4× cost upgrade exposed as a dropdown for specific posts that warrant it. **v0.8.2+**: calls route through the Cloudflare AI Gateway (same gateway we already use for OpenRouter — `gateway.ai.cloudflare.com/v1/{account}/{gateway}/workers-ai/@cf/black-forest-labs/...`) for response caching, unified cost/latency telemetry, and rate limiting. The 2026-04-15 regression that caused the gateway route to 403 on Workers AI has been resolved upstream; verified by direct probe on 2026-04-21. A `prautoblogger_cf_image_via_gateway` toggle (default on) falls back to the direct `api.cloudflare.com/client/v4/accounts/{id}/ai/run/...` URL if the gateway regresses again. The provider lives behind `PRAutoBlogger_Image_Provider_Interface`, so switching to a different image API (DALL-E, Replicate) is a new class implementation plus a one-line swap in the pipeline wiring.
|
||||
|
||||
### #15: Optional Cloudflare AI Gateway in front of OpenRouter
|
||||
We already use Cloudflare for DNS/CDN on peptiderepo.com, so layering AI Gateway in front of OpenRouter is zero marginal infrastructure. It gives us response caching (meaningful for repeated classification/scoring calls), a unified cost/latency dashboard, rate limiting, and provider fallback — all of which we would otherwise have to build ourselves to satisfy the CTO cost-tracking rules. Kept as an opt-in URL setting (`prautoblogger_ai_gateway_base_url`) so the plugin still works unchanged out of the box and can be bypassed instantly if the gateway misbehaves. The gateway is a transparent OpenRouter-compatible proxy; no new provider class is needed, and the response parsing path (`usage`, `choices[0].message.content`) is unchanged.

## [0.10.0] — 2026-04-21
|
||||
|
||||
### Removed
|
||||
|
||||
- **Cloudflare Workers AI as image provider.** The four `class-cloudflare-image-*`
|
||||
provider files are gone along with their unit tests and the three
|
||||
CF-specific options (`prautoblogger_cloudflare_ai_token`,
|
||||
`prautoblogger_cloudflare_account_id`, `prautoblogger_cf_image_via_gateway`).
|
||||
Runware FLUX.1 schnell produces equivalent-quality output at ~65×
|
||||
less cost and eliminates a duplicated settings surface. The
|
||||
`flux-1-schnell` registry entry that mapped to the CF provider is
|
||||
removed; the legacy slug now resolves to an empty provider (caught
|
||||
by the migration).
|
||||
|
||||
### Changed
|
||||
|
||||
- **Sites on any `cloudflare` image provider auto-migrate to
|
||||
`runware:100@1` on upgrade.** New migration
|
||||
`PRAutoBlogger_Migrate_Remove_Cloudflare_V0100::run()` runs from
|
||||
`admin_init` once per site. Detects three legacy shapes: registry-
|
||||
derived provider `cloudflare`, `prautoblogger_image_provider` option
|
||||
set to `cloudflare`, or the legacy slug `flux-1-schnell`. Sets
|
||||
`prautoblogger_image_provider` + `prautoblogger_image_model` to the
|
||||
Runware schnell pair and deletes the three dead CF options. Idempotent
|
||||
via `prautoblogger_migrated_remove_cloudflare_v0100` flag — running
|
||||
twice is a no-op and will not clobber a post-migration manual choice.
|
||||
- **Image provider dispatch fallback is now Runware, not Cloudflare.**
|
||||
`PRAutoBlogger_Image_Pipeline::create_default_provider()` returns
|
||||
`PRAutoBlogger_Runware_Image_Provider` for any unrecognised
|
||||
`prautoblogger_image_provider` value. An unmigrated install still
|
||||
gets a working pipeline instead of a fatal.
|
||||
|
||||
### Note
|
||||
|
||||
- **Cloudflare AI Gateway fronting OpenRouter is unaffected.** The
|
||||
`prautoblogger_ai_gateway_base_url` + `prautoblogger_ai_gateway_cache_ttl`
|
||||
options, their settings fields, `class-open-router-config.php`
|
||||
gateway resolution, and `class-open-router-request-builder.php`
|
||||
`cf-aig-cache-ttl` headers are all intentionally untouched. The AI
|
||||
Gateway is a proxy/cache layer in front of OpenRouter and is
|
||||
orthogonal to the CF Workers AI image provider removal. The
|
||||
migration test asserts this invariant explicitly.
|
||||
|
||||
### Cost impact
|
||||
|
||||
Zero recurring spend from CF Workers AI image generation (the
|
||||
peptiderepo.com install was still on CF as recently as v0.8.2 — see
|
||||
commit `80a7e11`). No new prompt tokens, no change in model mix for
|
||||
sites already on Runware or OpenRouter.
|
||||
|
||||
### Migration checklist (for anyone else running this plugin)
|
||||
|
||||
1. On first admin_init after upgrade, the migration will flip
|
||||
`prautoblogger_image_provider` to `runware` and
|
||||
`prautoblogger_image_model` to `runware:100@1` if you were on CF.
|
||||
2. **Set `prautoblogger_runware_api_key`** in Settings → Images if you
|
||||
hadn't already — image generation will fail until it is set.
|
||||
3. The CF API token + account ID options are deleted by the migration;
|
||||
you don't need to do anything.
|
||||
4. If you want to switch back to OpenRouter (Gemini) instead of
|
||||
Runware, just change the Image Model picker after the migration
|
||||
has run.
