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 Peptide_Linker class scans generated HTML and wraps every mention
of a known peptide in a hyperlink to its /peptides/ database page.
Runs as post-processing in Publisher — no LLM involvement, 100% reliable.
Handles case-insensitive matching, hyphen/space variants, skips existing
<a> tags. Gracefully no-ops if PR Core is not active.
Removed prompt-based peptide linking from Content_Prompts (unreliable).

When any peptide from the PR Core database is mentioned in a generated
article, the first mention is now automatically linked to its /peptides/
page. Gracefully degrades if PR Core is not active.
Extracted all prompt construction into Content_Prompts (252 lines),
slimming Content_Generator from 324 → 162 lines. Both under 300.

New submenu page showing all article ideas from the content analyzer.
Displays title, type, relevance score, frequency, key points, and
keywords with type filtering and pagination. Gives live visibility
into the idea pipeline.

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.

Two-pronged fix for repeated article topics:
1. Feed last 30 days of published article titles into the LLM analysis
prompt with explicit "avoid these" instruction. Zero cost — just
extra context in an existing API call.
2. Replace keyword-overlap dedup (60% word match) with embedding-based
cosine similarity via sentence-transformers/all-MiniLM-L12-v2 on
OpenRouter. Catches rephrasings that keyword matching misses
(e.g. "BPC-157 dosing" vs "how much BPC-157 to take"). Falls back
to keyword matching if the embedding API is unavailable.
Cost: ~$0.00001 per generation run ($0.02/M tokens, ~500 tokens/run).
New files:
- class-semantic-dedup.php — Embedding cosine similarity + keyword fallback
- class-open-router-embedding-provider.php — OpenRouter /embeddings client

The pipeline previously ran all articles sequentially in a single PHP
process. On Hostinger, this timed out at ~120s — enough for 1 article
but not 2+. Now the pipeline generates article 1 in-process, then
queues articles 2..N as individual WP-Cron events. Each article gets
its own PHP process with its own execution time budget, so we can
generate any number of articles regardless of server time limits.
Architecture:
- Pipeline_Runner: orchestrate (collect+analyze+score) + first article,
then serialize remaining ideas to wp_options and chain cron events
- Article_Worker (new): focused single-article worker extracted from
the pipeline loop — content gen + editorial + publish
- Executor: new on_process_article_queue() handler for chained events;
status poller re-schedules orphaned queue jobs automatically
- Article_Idea: added to_array() for queue serialization

Both Image A and Image B now fire concurrently through a single
generate_image_batch() call instead of sequentially. Total wall-clock
time equals the slowest image (~20s), not the sum (~40s), which
eliminates the Image B timeout problem on Hostinger where
max_execution_time killed the cron before the second request finished.
New files:
- class-open-router-image-batch.php — curl_multi orchestrator
- generate_image_batch() added to image provider interface
Pipeline refactored: prompts built upfront, single batch call, results
processed per-key. Cloudflare provider gets a sequential fallback.
Tests updated for batch API. All files under 300-line cap.

Extract PRAutoBlogger_Generation_Lock (DB mutex) and
PRAutoBlogger_Ajax_Handlers (image/model/test AJAX) from the
482-line executor. Executor retains generation cron/AJAX + model
registry at 299 lines. Document background generation flow in
ARCHITECTURE.md.

and class-settings-fields-extended to the file tree. Update
descriptions for split files to reflect new responsibilities.

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.

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 a one-paragraph pointer at the top of ARCHITECTURE.md so any
engineer working in this single-app repo can find the cross-app
engineering reference material — Cloudflare AI Gateway routing,
OpenRouter account sharing, the interface pattern, image-generation
stack, social distributor choice — and the incident runbook for
cross-app failure modes (distributor down, LLM provider revoked,
budget burn runaway).
The referenced docs live in the CTO workspace at
`Peptide Repo CTO/docs/engineering/` as the canonical source. If
those docs need to be visible from app-only Cowork sessions later,
we'll mirror or move them to a shared mount.
No code changes. Pure docs.

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).

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

PullPush.io index was frequently stale/unavailable. Reddit RSS/Atom feeds
work reliably from datacenter IPs (Hostinger) where .json gets 403.
- RSS is now the primary source for post fetching
- .json endpoints kept as fallback for posts and sole source for comments
- Deleted class-pull-push-client.php
- Updated admin UI, test connection handler, docs, and ARCHITECTURE.md
