* fix(image-pipeline): surface per-image failures in the event log
Two gaps made posts 650/657 appear to silently "lose" their featured
images on 2026-04-20:
1. The batch provider tagged each failed key with ['error' => ...] but
the ERROR log line it emitted didn't identify which key failed, so
operators couldn't tell image_a from image_b in the event log when
one of two parallel requests died.
2. Image_Pipeline::process_image_a/_b folded the per-key error into
$result['errors'] and returned silently, with no WARNING row. Ops
only learned about the miss when the outer catch in the caller fired
— and on the 2026-04-20 incident that outer catch didn't fire, so
nothing was logged at all except an unrelated pricing warning.
Fix:
- class-open-router-image-batch.php: collect_result() takes the request
key as its first argument and every Logger::error message reads
'OpenRouter batch image gen <class> for key "<key>": <detail>'.
Matches the shape of OpenRouter_Image_Support::log_retry.
- class-image-pipeline.php: process_image_a and process_image_b now
emit a Logger::warning('image_pipeline') row whenever $image_data is
missing or carries an error key, in addition to pushing to
$result['errors']. The warning fires whether or not the outer catch
runs.
Test: ImagePipelineTest::test_partial_batch_failure_emits_warning_log_row
mocks $wpdb, runs the pipeline with image_a erroring, and asserts at
least one warning/image_pipeline row was inserted.
No behavior change beyond logging; cost impact zero.

* feat(images): retry Cloudflare NSFW-blocked prompts with a sanitized fallback
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.

* feat(images): expose rewriter system prompt as admin setting
CEO feedback: every generated image is anchoring on the cartoon
peptide-with-arms-and-legs character because the hardcoded rewriter
system prompt both lists "anthropomorphized molecules" first in its
primer and ships a few-shot example that literally shows one. The ask
is to give CEO the lever without a code change.
Adds `prautoblogger_image_prompt_instructions` (textarea) in the
Images section. Default value is the existing REWRITER_SYSTEM_PROMPT
constant verbatim, so behaviour is unchanged on upgrade until someone
edits it. `Image_Prompt_Builder::rewrite_via_llm()` reads the option
at call time via a new `resolve_system_prompt()` helper and falls back
to the constant if the option is blank or whitespace-only, so a saved
empty value cannot brick image generation.
Const visibility flipped from `private` to `public` so the settings
field can reference it directly as the field default.
Tests:
- `test_rewrite_uses_setting_when_present` — option set, assert the
LLM's system message equals the option content.
- `test_rewrite_falls_back_to_default_when_setting_empty` — option
whitespace, assert the LLM's system message equals the constant.
Uninstall: new option covered by the existing prautoblogger_% LIKE
sweep in uninstall.php.
Cost impact: none by default. Future CEO edits will change prompt
length; current default is ~180 tokens, budget impact linear from
there.

* feat(images): collapse Image Provider + Image Model into a single dropdown
Until now, Image Provider and Image Model were two independent selects
in the admin UI. That let the CEO set Model=flux-1-schnell while
Provider was still openrouter — OpenRouter has no such model so every
image gen on posts 650/657 on 2026-04-20 returned HTTP 400, and the
article published without a featured image.
v0.8.0 removes the Image Provider field from the admin UI entirely.
The provider is now derived from the model's entry in the registry
every time the model is saved. A new
PRAutoBlogger_Image_Model_Registry::provider_for() helper centralises
the mapping, so admin save, the on-upgrade migration, and future
callers all read from one place.
On save, PRAutoBlogger_Admin_Page::sanitize_image_model() validates
the submitted slug against the registry:
- Known slug: persist it, and update `prautoblogger_image_provider` to
the paired provider as a side-effect.
- Unknown slug: add_settings_error with a clear message, and return
the previously-saved value so the site stays on a working model.
A one-shot v0.8.0 migration in
PRAutoBlogger::on_check_db_version() derives the provider from the
currently-saved model on first admin_init after the plugin is updated.
This auto-heals sites that were running mismatched pairs before the
upgrade, without requiring the admin to re-open settings.
`prautoblogger_image_provider` option key is preserved — all existing
reads in the pipeline, cost tracker, and validators continue to work
unchanged.
Tests (Services/ImageModelRegistryTest):
- Every registry entry has an id and a provider in {openrouter, cloudflare}.
- provider_for() returns the paired provider for a known slug.
- provider_for() returns '' for unknown/empty slugs.
Cost impact: none.
Migration idempotent via the `prautoblogger_migrated_image_provider_v080`
flag. Uninstall sweeps it along with every other plugin option.

* chore(v0.8.0): version bump + CHANGELOG + ARCHITECTURE.md for image bundle
Bump plugin header and PRAUTOBLOGGER_VERSION 0.7.3 → 0.8.0. Minor bump
because Commit D removes the Image Provider dropdown from admin (a
UX-visible change), not a patch.
CHANGELOG:
- Changed: collapsed Image Provider + Model dropdowns; provider derived.
- Added: Image Prompt Instructions setting; Retry NSFW-Blocked Images
setting.
- Fixed: silent per-image failures in the event log.
ARCHITECTURE.md:
- Stage 6b (Image Pipeline) callout now describes provider derivation
and the NSFW-retry fallback path.
- wp_options table lists the four new/changed keys
(`prautoblogger_image_provider` as derived, new
`prautoblogger_image_prompt_instructions`,
`prautoblogger_image_nsfw_retry`, and the one-shot migration flag
`prautoblogger_migrated_image_provider_v080`).
DB schema unchanged — no PRAUTOBLOGGER_DB_VERSION bump needed.
Final commit of the v0.8.0 image bundle (thread image-mime-bug).

New "Display" admin section with three settings:
- Article Font (7 choices + theme default, Google Fonts loaded on demand)
- Article Font Size (px, 0 = theme default)
- Table Borders (toggle, on by default — adds borders, padding, striping)
Inline CSS injected via wp_head only on singular posts with
_prautoblogger_generated meta — zero impact on other pages.
Extracted Image_Model_Registry to keep settings-fields-extended under
300 lines.
Bump 0.6.3 → 0.7.0.

New data source that sends a configurable research prompt to a
reasoning-capable model (Grok 4.1 Fast, DeepSeek-R1, etc.) to identify
trending topics, content gaps, and emerging questions. Findings feed
into the content analyzer alongside Reddit data, combining real-time
community signals with deep knowledge-base research.
New admin settings: Research Model picker, Research Prompt textarea,
and LLM Deep Research toggle in Enabled Sources.

Enables reasoning-capable models (Grok 4.1 Fast, DeepSeek-R1, etc.)
via new admin settings: Enable Reasoning toggle and Reasoning Effort
selector. Provider auto-injects reasoning params when enabled; callers
can override per-call via options array. Response parser captures
reasoning_tokens and reasoning_content for visibility.

Three fixes in one:
1. Duplicate image: prepend_caption_to_post() was embedding the full
image + caption as a <figure> block, but the theme already displays
the featured image. Now only the caption text is prepended — no
second copy of the image.
2. Hardcoded model names: removed all FLUX.1/FLUX.2 references from
model-agnostic code (pipeline, prompt builder, sideloader, OpenRouter
provider, interface, admin labels). The Cloudflare provider still
references FLUX since it specifically wraps that model family.
3. Test alignment: OpenRouterImagePricingTest was asserting against
removed models (flux-2-pro, seedream). Updated to match current
COST_PER_IMAGE entries (Gemini Flash, GPT-5 Image).

Three issues found in activity logs:
1. Image model IDs stale — FLUX and Seedream removed from OpenRouter.
Updated to current models: Gemini 2.5/3.1 Flash Image, Gemini 3 Pro
Image, GPT-5 Image/Mini. Default changed to gemini-2.5-flash-image.
2. openrouter/free router wraps upstream 429 errors in HTTP 200 body
with error object. Both text and image response parsers now detect
this pattern and surface a proper RuntimeException.
3. Image request used modalities: ["image"] but Gemini needs
["image", "text"]. Updated to include both.

Replaces Cloudflare Workers AI (FLUX.1 schnell) as the default image
provider with OpenRouter, which offers FLUX.2 Pro, Seedream 3.0,
Gemini Flash Image, and GPT Image 1 at comparable or better pricing.
- New provider class (3-file split: provider, pricing, support) reuses
the existing OpenRouter API key and Cloudflare AI Gateway
- Admin settings: new Image Provider dropdown (openrouter/cloudflare),
model picker shows all available image models from both providers
- Image pipeline auto-selects the configured provider at construction
- Cost logging now uses actual model name instead of hardcoded flux-1-schnell
- Default model changed to black-forest-labs/flux-2-pro ($0.03/image)
- Unit tests for pricing resolution and provider response parsing
Cost impact: FLUX.2 Pro at $0.03/image vs schnell at $0.0007/image —
~43x more expensive per image, but dramatically better quality. At 2
images/article × 1 article/day = ~$1.80/month. Seedream 3.0 ($0.003)
available as a budget alternative.

Apply the same interactive model picker UI to the image model field.
Since Cloudflare models don't come from OpenRouter's registry, the
two FLUX models are embedded as static data in the page config and
the JS popup renders cost-per-image instead of token pricing.
