Behaviour
| Fact | Value | Source |
|---|---|---|
| Fail-open | No verdict for any reason → entry admitted, marked "Not scored" with a reason; never marks spam without a clean verdict at or above threshold | plugin/src/SpamGate.php, INVARIANT tests |
| Never overturn | An entry another plugin already marked spam is left alone, no call made | same |
| Time budget | 3 s hard wall in the plugin; engine p95 target ≤ 1.5 s | spec 00 constraint 1 |
| Learning | Site owner's corrections become examples for that site's later submissions; no fine-tuning, no cross-customer model | spec 00 constraint 5 |
| Site profile | Built automatically from the site's public pages at activation, on manual re-crawl, and about every 60 days; nothing behind a login | backend/src/crawl/ |
| Field exclusion | Per-field opt-out; excluded values never leave the site; file uploads sent as name + label only | plugin/src/RequestBuilder.php |

Privacy posture
| Fact | Value | Source |
|---|---|---|
| Roles | The WordPress site is the controller; GravityAgent is a transient processor | CONTEXT.md, docs/legal/dpa.md |
| Content storage | No submission content is ever stored: not in a database, log, cache or backup; enforced by sentinel-leak tests on every table and the log sink | backend/test/decide.test.ts |
| Kept | Non-content decision records (ids, label, confidence, model, latency, tokens) for ~90 days; daily outcome counts; site profile and owner notes until deactivation | docs/legal/privacy.md |
| Training | Never; the LLM provider is used on Gemini API paid-tier terms that forbid it | docs/legal/subprocessors.md |
| Location | Stored data US-only (Cloudflare D1, ENAM); in-flight processing at the nearest Cloudflare edge and at Google | docs/legal/privacy.md §4 |
| Subprocessors | Cloudflare, Google (Gemini API), Firecrawl (crawl only), Freemius (paid checkout only) | docs/legal/subprocessors.md |
| Deletion | Deleting the entry deletes the content; deactivating the site deletes its profile and notes immediately | ticket 32 |
