Requirements 1-8 + all non-negotiables:
1. Model manager (CRUD): PRV_Model_Registry, prv_models v2 option, versioned
idempotent migration from v0.1.x flat-string format, Settings page CRUD.
2. Per-model run-health: PRV_Model_Registry::update_health() after each run;
health badges (Healthy/Retired?/Disabled/Unknown) in model table + dashboard.
3. Metric comparability: PRV_Config_Version stamps every run with config_version;
save-bar warning on scoring-relevant changes; orphaned rows excluded by version.
4. Projected cost at save: PRV_Config::get_projected_cost(); over-cap warning;
prv_last_run_truncated option + visible notice when cap hit mid-run.
5. Config surface: peptide set, intents, cadence (reschedules cron), budget cap;
all validated + sanitized; next-run timestamp shown.
6. API-key three-state: not-defined / defined-ok / defined-failed; derived from
ledger; never displays the key.
7. Run-lock: PRV_Run_Lock (transient); cron tick skips if locked; Run-now
refuses with clear message; lock released in finally block.
8. Design fixes: dark-ink focus ring on bright fills; disabled-row full AA
contrast (no opacity); toggle disabled on retired rows; save-bar-level
warning (role=alert); chip text #B4BDC7 6.83:1 AA; keyboard-sortable headers
(<button>+aria-sort); aria-live on Test chip; z-index:50 save-bar;
run-now double-fire guard; @media print light overrides.
New: PRV_Upgrader (runs migrations on plugins_loaded, not just activation),
PRV_Config_Version, PRV_Run_Lock, PRV_Settings_Page, PRV_Settings_Renderer,
PRV_Model_Manager_Table, PRV_Model_Test_Ajax.
Tests: test-model-registry, test-run-lock, test-config-version,
test-projected-cost, test-cron-reschedule (+ updated probe-runner,
uninstall, bootstrap).
Schema: config_version INT column added via dbDelta (idempotent).
Uninstall: purges all v0.2 prv_* options + transients.
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.
