Add PRV_Cron_Guard: idempotent init-hook guard that re-schedules
prv_weekly_probe and prv_daily_prune when missing (e.g. after
an rsync deploy that bypasses the activation hook).
- New class: includes/core/class-prv-cron-guard.php
- Hooks on init; two wp_next_scheduled() checks on hot path
- Delegates to PRV_Cron::schedule() and PRV_Prune_Cron::schedule()
so recurrence + offset are always canonical (no inline divergence)
- Idempotent: no-op when events already scheduled
- PRV_Plugin::init(): wires PRV_Cron_Guard::register_hooks()
- Tests: tests/unit/test-cron-guard.php (missing, idempotent, recurrence)
- Bump version 0.3.0 -> 0.3.1 (header + PRV_VERSION constant + bootstrap)
- CHANGELOG: [0.3.1] entry
PR Vision
An internal WordPress plugin that runs weekly server-side LLM probes to measure whether peptiderepo.com is cited by AI assistants across core peptides.
v0.1.0 — AI-visibility dashboard only. Internal use; no public-facing output.
Purpose
GEO (Generative Engine Optimization) is peptiderepo.com's #1 strategic goal. This plugin provides the measurement instrument: weekly LLM probes → time-series storage → admin trendline + per-peptide standings.
The displayed metric is a directional proxy — API probes do not replicate the consumer ChatGPT/Gemini experience (different retrieval, personalisation, and system prompts), but they provide a consistent, trackable signal.
Required wp-config.php constants
// OpenRouter API key (sk-or-…) — required for all providers.
define( 'PRV_OPENROUTER_API_KEY', 'sk-or-YOUR_KEY_HERE' );
// Cloudflare AI Gateway routing (optional — falls back to direct OpenRouter).
define( 'PRV_CF_ACCOUNT_ID', 'YOUR_CF_ACCOUNT_ID' );
define( 'PRV_CF_GATEWAY_ID', 'YOUR_GATEWAY_NAME' );
Never commit these values. They are read at runtime from wp-config.php only.
Architecture
See ARCHITECTURE.md for the full file tree, data flow, and design decisions.
Admin page
Navigate to PR Vision in the WordPress admin sidebar (manage_options required).
The page shows:
- A proxy-metric disclaimer note.
- A Chart.js trendline of the visibility score across runs.
- A per-peptide standings table (cited?, our position, top competitor domains).
- Month-to-date cost vs. the monthly cap.
- A "Run now" button to trigger an on-demand probe run.
Scheduling
A weekly WP-Cron event (prv_weekly_probe) is registered on plugin activation and cleared on deactivation. Probe runs (cron or manual) respect the hard monthly budget cap.
Cost cap
Default cap: $5.00 USD/month (configurable via the prv_monthly_budget_usd option). The runner checks the month-to-date spend before each API call and stops gracefully when the cap is reached — partial runs are recorded, never over-spend.
Uninstall
Uninstalling the plugin drops the {prefix}prv_ai_visibility table and deletes all prv_* options. Deactivation only clears the cron schedule.
