Peptide News Aggregator v2.6.0 — Complete Implementation & Deployment Plan

Target Architecture:

• Shared Hosting Server: Prepaid WordPress hosting (MySQL Database wp_peptide_news_articles, public WordPress frontend, Admin UI).
• Hostinger KVM8 VPS (Coolify): Dedicated VPS running Coolify to execute the standalone worker (tools/vps-worker/) for heavy 3-step OpenRouter LLM processing, PubMed XML extraction, and Google News URL redirect unwrapping.

---

1. Current Codebase Status (100% Implemented & Verified)

All v2.6.0 features and adversarial security hardenings have been implemented in c:\Users\terence\Projects\peptidenews:

• 89/89 PHPUnit tests passing (vendor/bin/phpunit).
• REST API Worker Routes (/wp-json/peptide-news/v1/worker/*): Authenticated via X-Peptide-News-Token (with timing-safe comparison and automatic token decryption).
• Standalone Coolify Worker (tools/vps-worker/): Complete with Dockerfile, docker-compose.yml, and worker.php supporting both CLI arguments and Coolify environment variables (WP_URL, VPS_TOKEN, OPENROUTER_KEY, OPENROUTER_MODEL, WORKER_ACTION, BATCH_SIZE).
• 3-Step AI Pipeline:
  • Step 1 (Gatekeeper): Assigns scientific rigor score (1–10) and classifies study type. Rejects low-quality/promotional spam (score < 3 or is_spam = true) by setting 'is_active' => 0.
  • Step 2 (Extraction): Extracts target peptides, mechanism, experimental model, and keywords, saving checkpoint to ai_metadata.
  • Step 3 (Generation): Creates a 300–500 word structured Markdown summary (## Executive Summary, ## Scientific Context & Mechanism, etc.).

2. Instructions for the Agent: Step-by-Step Execution

Step 1: Package as an Installable WordPress Plugin ZIP

Before deploying to WordPress, create a clean, installable ZIP archive (peptidenews-v2.6.0.zip) that can be uploaded directly via WordPress Admin -> Plugins -> Add New -> Upload Plugin:

1. From the parent directory of peptidenews, generate a clean zip archive containing the peptidenews/ root folder while excluding development, test, and git files:

   # Linux / macOS / Bash:
   zip -r peptidenews-v2.6.0.zip peptidenews/ \
       -x "peptidenews/.git/*" \
       -x "peptidenews/tests/*" \
       -x "peptidenews/phpunit.xml*" \
       -x "peptidenews/.phpunit*" \
       -x "peptidenews/scratch/*" \
       -x "peptidenews/*.md"
   

   (On Windows PowerShell, use Compress-Archive -Path .\peptidenews -DestinationPath .\peptidenews-v2.6.0.zip after excluding tests and .git).
2. Verify ZIP Archive Structure: Ensure peptidenews/peptide-news-plugin.php is located at the top level inside the zip archive so WordPress correctly recognizes it as a valid plugin.

Step 2: Deploy & Configure WordPress on Shared Hosting

1. Upload and install peptidenews-v2.6.0.zip via WordPress Admin or extract it into /wp-content/plugins/peptidenews/ on the shared WordPress server.
2. In WordPress Admin -> Settings -> Peptide News:
   • Under NCBI API Key, enter an NCBI API key (optional, increases PubMed rate limit to 10 req/sec).
   • Under VPS Worker Integration, enter a strong secret token (e.g., coolify_secret_token_2026) and save.
3. Verify the REST API endpoint responds correctly:

   curl -i -H "X-Peptide-News-Token: coolify_secret_token_2026" \
        "https://your-wordpress-site.com/wp-json/peptide-news/v1/worker/pending?limit=5"
   

Step 3: Deploy Worker Application to Coolify (Hostinger KVM8 VPS)

Use the Coolify UI or Coolify MCP to create and configure the standalone worker:

1. Create Application in Coolify:
   • Add a new Application and point it to the repository (or upload tools/vps-worker/).
   • Set Build Pack to Dockerfile with path tools/vps-worker/Dockerfile.
2. Configure Environment Variables in Coolify:

   WP_URL=https://your-wordpress-site.com
   VPS_TOKEN=coolify_secret_token_2026
   WORKER_ACTION=process-llm
   OPENROUTER_KEY=sk-or-v1-your-openrouter-api-key
   OPENROUTER_MODEL=google/gemini-2.0-flash-001
   BATCH_SIZE=25
   

3. Configure Scheduled Task (Coolify Cron):
   • Under Scheduled Tasks / Cron Jobs for the application, create a new schedule:
     • Cron Expression: 0 * * * * (runs hourly)
     • Command: php /app/worker.php
   • Click Deploy to build and launch the Alpine PHP container.

3. Automated Verification Checklist for the Agent

1. Verify Plugin ZIP Installation: Confirm peptidenews-v2.6.0.zip installs and activates cleanly in WordPress Admin without warnings or missing dependencies.
2. Run Unit Tests Locally: Execute vendor/bin/phpunit and confirm OK (89 tests, 231 assertions).
3. Test One-Off Execution in Coolify:
   • Trigger the Coolify scheduled job or run php /app/worker.php --action="pending" inside the container.
   • Confirm it connects to WordPress without HTTP 403 or 500 errors.
4. Check Gatekeeper Database State:
   • Confirm in WordPress Admin that legitimate scientific articles (rigor_score >= 3) receive structured Markdown summaries and tags.
   • Confirm that rejected promotional spam (rigor_score < 3 or is_spam) is automatically updated with 'is_active' => 0 and excluded from frontend widgets.
