Piece 1 — Visuals - Add KPI bento bar (score tile with run-health pill, cost tile, last-run tile). Run-health pill shows 'All models healthy' / 'N model(s) degraded' / 'No run yet' sourced from PRV_Model_Registry health fields via collector. - Add config-change trendline marker: inline configMarker Chart.js plugin draws a vertical dashed orange line + pin at every config_version boundary. Legend swatch + annotation note appear when breaks exist. - Chart sits in fixed .prv-chartbox (300px); typeof-Chart guard + .prv-noscript fallback — cannot grow layout, degrades gracefully offline. - PRV_Dashboard_Renderer: new class owns bento tile + trendline rendering. PRV_Ai_Visibility_Panel is now a thin orchestrator (237 lines). - PRV_Ai_Visibility_Collector: trendline query now includes MIN(config_version) per run; collect() adds last_run_counts and config_versions to payload. - PRV_Admin_Page: get_dashboard_css() returns Assay dark palette CSS. Piece 2 — Deploy pipeline - .github/workflows/deploy.yml: on push to main, runs CI, rsyncs plugin to Hostinger PROD (excl. .git .github tests phpunit composer vendor phpcs *.md), purges LiteSpeed, health-checks (200/403). Standalone — not smoke-gated. DoD - Version 0.2.1 in header + constant; CHANGELOG, ARCHITECTURE, CONVENTIONS, CONTEXT all updated same commit. - tests/unit/test-dashboard-panel.php: 27 assertions. - Pre-push checks: no PHP built-in name shadows in bootstrap.php; all includes/*.php files <= 300 lines (max: 298).

# Architecture — PR Vision
|
||
|
||
**Version:** 0.2.1 | **Last updated:** 2026-06-14
|
||
|
||
---
|
||
|
||
## 1. Overview
|
||
|
||
`pr-vision` is an internal WordPress plugin that runs configurable server-side LLM probes to measure whether peptiderepo.com appears in AI citations across core peptide queries. It stores a time-series in a custom table and renders an admin dashboard (trendline + standings) and a full Settings page (model manager + probe config).
|
||
|
||
**v1 scope:** AI-visibility only. The collector/panel seam is present so future data categories can be added as new classes.
|
||
**v2 additions:** Model manager CRUD (no deploy needed), config-version tracking, run-lock, projected cost, API-key three-state, dark "Assay" Settings UI.

|
||
|
||
## 5. External API integrations
|
||
|
||
### Cloudflare AI Gateway
|
||
All LLM calls route through:
|
||
```
|
||
https://gateway.ai.cloudflare.com/v1/{PRV_CF_ACCOUNT_ID}/{PRV_CF_GATEWAY_ID}/openrouter
|
||
```
|
||
Falls back to direct OpenRouter when the constants are absent.
|
||
|
||
### Providers (v0.1 + v0.2 UI-managed)
|
||
|
||
| Provider | Model | Citation source |
|
||
|----------|-------|-----------------|
|
||
| PRV_Perplexity_Provider | `perplexity/sonar` | `citations[]` array |
|
||
| PRV_OpenRouter_Provider | any OpenRouter slug | annotations or inline URL regex |
|
||
|
||
Models are now managed via the Settings UI rather than hardcoded. The `prv_models` option is the source of truth; `PRV_Config::get_models()` delegates to `PRV_Model_Registry::get_enabled_slugs()`.
|
||
|
||
---
|
||
|
||
## 6. Collector / Panel seam
|
||
|
||
Same as v0.1.0 -- see CONTEXT.md for the extension guide.
|
||
|
||
---
|
||
|
||
## 7. Security
|
||
|
||
- Secrets read from `wp-config.php` constants at runtime -- never stored in DB.
|
||
- API key status shown in 3 states; key never displayed.
|
||
- All admin actions: `manage_options` check + nonce verification.
|
||
- All DB values escaped with `$wpdb->prepare()`.
|
||
- All HTML output escaped at render.
|
||
- AJAX `prv_test_model`: capability + nonce + 30s rate-limit transient.
|
||
|
||

|
||
|
||
## 8. Key decisions
|
||
|
||
| Decision | Rationale |
|
||
|----------|-----------|
|
||
| `prv_models_schema_version` for migration gate | Cheap option check; migration is idempotent and safe to call on every plugins_loaded without performance cost. |
|
||
| Config-version as hash + version-number | Hash detects changes; integer version is stable foreign key for run rows and chart annotations. Orphaned rows (NULL config_version or old version) are excluded from current-config scoring. |
|
||
| Run-lock as transient | WP transients work across all environments; TTL guards against stale locks from crashed runs; no separate table needed. |
|
||
| Projected cost from probe_count × fixed estimate | Conservative overestimate; avoids the need for per-model price config in v1; operator sees a safe upper bound. |
|
||
| Three-state API key (not two) | A defined-but-revoked key showed false-green in v1 (QA finding M4). The third state "defined, last run failed" closes that gap without ever displaying the key. |
|
||
| Sticky save-bar warning (not just card banner) | Card banner scrolls off; save-bar is always in viewport on a page with a tall model table (QA finding M2). |
|
