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.

Root cause: both attach_generated_images() in post-assembler and the
retroactive handler in executor passed null as source_data to the image
pipeline. The pipeline's Image B branch requires non-null source_data
to fire, so Image B was silently skipped on every article since the
feature was built.
Fix: added get_source_data_for_image() to Source_Collector to retrieve
the original Reddit post title/content by source_ids. Post-assembler
now pulls source_ids from the Article_Idea; executor pulls them from
the _prautoblogger_source_ids post meta saved by the publisher.
Also added a regression test proving Image B is skipped when source_data
is null, so this handoff gap will be caught if re-introduced.

FLUX.1 [dev] was removed from Cloudflare Workers AI in April 2026,
returning HTTP 400 "No route for that URI". This removes it from the
static model picker list and pricing calculations. Any saved setting
referencing flux-1-dev gracefully falls through to flux-1-schnell
via the null-coalesce in resolve_model().

prautoblogger_cloudflare_ai_token was missing from the $encrypted array
in sanitize_field(), so the token was stored as plaintext. On read,
decrypt() failed on the non-encrypted value and returned empty string,
causing HTTP 401 on every Cloudflare Workers AI call.
Fix: add the field to the encrypted list so future saves encrypt it.
Also add legacy plaintext detection in get_api_token() and the validator
so the existing DB value works immediately and gets auto-encrypted on
first use.

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.

Replace plain text inputs for analysis/writing/editor model fields
with a rich model picker that fetches the OpenRouter model registry
and displays a searchable popup with model name, provider, input/output
pricing per 1M tokens, and context window. Also extracts source status
and model field renderers into dedicated field classes to keep
class-admin-page.php under the 300-line cap.
New files:
- assets/js/model-picker.js — popup UI with search, filtering, caching
- assets/css/model-picker.css — popup styles matching admin design system
- includes/admin/fields/class-open-router-model-field.php — server render
- includes/admin/fields/class-source-status-field.php — extracted field

Replaces the rule-based prompt builder with a cheap LLM call
(analysis model via OpenRouter) that distills article content into
concise visual scene descriptions. The old rule-based method becomes
the fallback if the LLM call fails.
Key design decisions:
- System prompt teaches the LLM to describe objects/setting/lighting
instead of abstract concepts, and to avoid faces (FLUX.1 weakness)
- Uses the analysis model (gemini-2.5-flash-lite) at ~$0.001/call
- Cost is logged to the analytics dashboard via log_api_call()
- Style suffix is still appended separately so the rewriter only
handles scene composition
Cost impact: +~$0.001 per image on top of ~$0.0008 generation cost.

Adds wp_ajax_prautoblogger_generate_image so images can be generated
for existing posts that were published before image gen was enabled
or fixed. Uses set_time_limit(120) to handle the Cloudflare API
latency that caused fatals when run via Code Snippets init hook.

FLUX.1 schnell requires width and height to be divisible by 8.
The default OG image size 1200×630 has 630 % 8 = 6 remainder,
causing HTTP 400 on every image generation call.
Changes:
- Pipeline default height 630 → 632 (nearest 8-aligned value)
- Provider now rounds any dimension to nearest multiple of 8 as
a defensive guard before sending to the API

The sanitize_field() fallthrough for JSON fields starting with '['
called sanitize_text_field() which escaped quotes and brackets,
breaking json_decode() on read. This caused subreddits, topic
exclusions, and enabled sources to always read back as empty arrays.
Now properly decodes, sanitizes each item, and re-encodes as clean
JSON for all three input paths: PHP array, JSON string, or CSV.

The $encrypted array was missing prautoblogger_cloudflare_ai_token,
so saving through the admin UI stored plaintext while the read path
called decrypt() — which would fail on non-encrypted data.

Move system prompt, user prompt, and performance context builders into
PRAutoBlogger_Analysis_Prompts. Analyzer retains orchestration, data
fetch, parsing, and storage. Backward-compatible private proxies kept.

Extract schedule, publishing, analytics, and images field definitions
into PRAutoBlogger_Settings_Fields_Extended. Core class retains sections

Cron handlers (daily generation, metrics collection), AJAX handlers
(generate now, test connection), atomic generation lock, and model
registry access moved to PRAutoBlogger_Executor. Main orchestrator
retains hook registration, DB migrations, and cron schedule filter.
Backward-compatible proxy methods on PRAutoBlogger.

The custom autoloader converts PRAutoBlogger_OpenRouter_Model_Registry
to class-open-router-model-registry.php (hyphen between Open and Router),
but the files were named class-openrouter-model-registry.php. This caused
a fatal "Class not found" error on every uncached page load.
Renames:
- class-openrouter-model-registry.php → class-open-router-model-registry.php
- class-openrouter-model-normalizer.php → class-open-router-model-normalizer.php
Updates @see references in interface, ARCHITECTURE.md, and CHANGELOG.md.

Extracted credential validation, request building, response parsing, and
configuration helpers from the 464-line OpenRouter provider into separate,
focused classes. This follows the pattern established by the Cloudflare
image provider and brings all files under the project's 300-line limit.
Files created:
- class-open-router-validator.php (152 lines): Handles credential validation
with HTTP probes and diagnostic messaging. Delegates from the provider.
- class-open-router-config.php (84 lines): Centralizes admin config resolution
for API base URL and cache TTL settings. Used by both provider and validator.
- class-open-router-request-builder.php (79 lines): Encapsulates request header
building and cURL auth filter registration for hosting environments that
strip Authorization headers.
- class-open-router-response-parser.php (87 lines): Handles response parsing,
error classification, and retry-decision logic.
- Tests: OpenRouterValidatorTest.php with comprehensive credential checks.
Provider shrinks from 464 to 278 lines. All classes are under 300 lines.
Dependencies remain clean: validator and config are independent, request-builder
and response-parser have no circular imports.

Extract parse_atom_feed() and RSS-specific XML parsing logic into a new
PRAutoBlogger_Reddit_RSS_Parser class. This parser is a self-contained data
transformation (Atom XML → normalized post array) with minimal dependencies.
File sizes after split:
- class-reddit-json-client.php: 371 lines (was 468)
- class-reddit-rss-parser.php: 137 lines (new)
Both files now under the 300-line cap. The JSON client retains post/comment
fetching, availability checks, and HTTP infrastructure, while the parser
handles the XML-to-array transformation in isolation.
No callers need updating — PRAutoBlogger_Reddit_Provider uses
fetch_posts() which internally delegates to the parser.

Extract read-only reporting methods from PRAutoBlogger_Cost_Tracker into a new
PRAutoBlogger_Cost_Reporter class. This reduces Cost_Tracker from 313 to 206
lines and Reporter to 141 lines, both under the 300-line cap.
Changed files:
- Create includes/core/class-cost-reporter.php with reporting methods:
* get_monthly_spend(): float
* get_daily_spend(int $days = 30): array
* get_spend_by_stage(string $start_date, string $end_date): array
* get_budget_utilization(): float
- Update includes/core/class-cost-tracker.php:
* Remove reporting methods
* Update is_budget_exceeded() and would_exceed_budget() to use Cost_Reporter
* Keep get_current_run_cost() (tracks current pipeline run only)
* Add @see cross-reference to Cost_Reporter
- Update templates and admin classes to instantiate Cost_Reporter:
* templates/admin/metrics-page.php
* templates/admin/settings-page.php
* includes/admin/class-admin-notices.php
* includes/admin/class-dashboard-widget.php
- Split tests/unit/Core/CostTrackerTest.php:
* Create tests/unit/Core/CostReporterTest.php for reporter methods
* Keep run ID and budget enforcement tests in CostTrackerTest
Autoloader automatically discovers PRAutoBlogger_Cost_Reporter class.

Completes the image + A/B experiment workstream by integrating
image generation into the post publishing pipeline.
New classes:
- class-image-pipeline.php: Orchestrates A/B generation (article-driven
Image A → featured; source-driven Image B → post meta). Each image
independently fallible; article publishes even if both fail.
- class-image-prompt-builder.php: Synthesizes visual prompts from article
title+content and Reddit source data. Appends CEO-locked 90s infomercial
style suffix. Keeps prompts concise for FLUX.1 quality.
- class-image-media-sideloader.php: Downloads image bytes, creates temp
file, sideloads via media_handle_sideload(), sets alt text and metadata,
cleans up temp files.
Changes to existing files:
- Publisher.attach_generated_images(): Runs image pipeline post-creation,
sets _thumbnail_id (Image A) and _prautoblogger_image_b_id (Image B).
Errors logged but don't block post publication.
- Settings: prautoblogger_image_enabled (toggle, default off).
Tests:
- ImagePipelineTest.php: Orchestration, cost tracking, graceful failures.
- ImagePromptBuilderTest.php: Prompt generation, length limits.
Docs:
- ARCHITECTURE.md: New step 6b in data flow, new files in file tree.
- CHANGELOG.md: Commit 1a/1b breakdown.

Foundation for the smart model picker. Fetches, normalizes, and caches
the OpenRouter model list (/api/v1/models — free, unauthenticated).
Daily refresh via the existing prautoblogger_daily_generation cron with
12h idempotency. 3-retry exponential backoff on transient failures;
serves last-good option payload when stale-and-fetch-fails.
New files:
- interface-model-registry.php — Phase 3-aware contract (94 lines)
- class-openrouter-model-registry.php — fetch + cache + query (226 lines)
- class-openrouter-model-normalizer.php — raw → standardized (114 lines)
Zero-coupling: no PRAUTOBLOGGER_* constants inside the service classes.
Config injected via constructor. Phase 2 lift into a shared Composer
package requires only namespace rename, zero internal edits.
Cost impact: $0/month (free endpoint, no LLM tokens).

Implements image-provider interface + Cloudflare Workers AI adapter with pricing and validator. Independent QA verdict: APPROVE on 52fd11e (qa-reviews/prautoblogger/2026-04-15-52fd11e2ce97dd9e659df5cc87ec1382a668bec1.md). All 4 CTO blockers resolved (PHPUnit retry mocks, XSS hardening on error strings, PHPCS on new files, 300-line cap via support-class extraction). PHPCS backlog (586 errors across 38 pre-existing files) remains on continue-on-error; Workstream C material.
Adds two WP options: prautoblogger_ai_gateway_base_url (routes OpenRouter calls through a Cloudflare AI Gateway when set to an https:// URL; empty = direct, the default) and prautoblogger_ai_gateway_cache_ttl (seconds for cf-aig-cache-ttl response caching; 0 = off).
The gateway is a transparent OpenRouter-compatible proxy, so no consuming class, no provider abstraction, and no response-parsing path changes. The http_api_curl belt-and-suspenders Authorization filter is rescoped to the configured upstream host so it still runs under gateway.ai.cloudflare.com.
Rationale: leverages existing Cloudflare infrastructure to satisfy the CTO cost-control rules (caching, cost tracking, rate limiting, fallback) without building equivalent middleware in-plugin. Fully opt-in and reversible from the admin UI.
Docs: ARCHITECTURE.md options + integrations tables updated; key decision #15 added. Uninstall is unaffected (wildcard prautoblogger_% delete).

WordPress's get_the_title() returns HTML-encoded entities (e.g., ’
for smart quotes). Since the React component renders via createElement
(textContent, not innerHTML), these entities displayed as raw text.
Fix applied at two levels:
- PHP REST endpoint: html_entity_decode() before sending JSON response
- JS PostCard component: decodeEntities() safety net for any residual
encoded entities from other sources

Root cause of the 401 was a corrupted API key: the WordPress auth
salt changed after the key was encrypted, so decryption produced
garbage instead of sk-or-... OpenRouter interprets the garbled
Bearer token as "Missing Authentication header."
Adds the same sk-or- prefix check to the credential validation
method so users see a clear "re-enter your key" message instead
of a cryptic 401 error.

Hostinger's hosting environment appears to strip the Authorization
header from outgoing wp_remote_post requests before they reach the
cURL transport. This caused OpenRouter to respond with HTTP 401
"Missing Authentication header" even though the header was set in
the wp_remote_post args array.
Fixes:
- Add http_api_curl filter (priority 99) that re-sets the
Authorization header directly on the cURL handle, bypassing any
intermediate header stripping. Scoped to openrouter.ai URLs only.
- Applied to all three OpenRouter call sites: send_chat_completion,
validate_credentials_detailed, and get_available_models.
- Filter is cleaned up in a finally block to avoid leaking.
Also:
- Add pre-flight key format validation (must start with "sk-or-")
to catch corrupted decryption early with a clear error message.
- Fix retry condition: was `>= 429` (incorrectly retried 430-499),
now `=== 429` (only retry rate-limit).
- Add detailed diagnostic logging on 401/403 auth failures.
- Add .env.credentials to .gitignore.

Address CTO audit findings for PRAutoBlogger:
- CI pipeline now runs PHPCS (WordPress standards) and PHPUnit before deploy
- Removed TikTok/Instagram/YouTube stub providers (dead code, not registered)
- Rewrote PublisherTest with real behavioral assertions (post_status, metadata,
taxonomy, log linking, hooks) instead of method-existence checks
- Added cross-system LLM budget coordination docs to ARCHITECTURE.md
- Bumped version to 0.2.2

LLMs sometimes ignore format instructions and wrap content in markdown
code fences or full HTML document structures. Added sanitize_llm_content()
