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.

Add class-executor, class-post-assembler, class-analysis-prompts,
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
