## What Replaces the **mocked** "Free PDF Editors" fleet card on the portal Usage page with live figures. Cost stays a literal `$0`; any figure that can't be computed renders **N/A** (never a misleading 0). | Metric | Self-hosted source | |---|---| | **Editors deployed** | total users (`UserRepository.count()`) | | **Active this month** | distinct `source=WEB` principals active in 30d (excl. `UI_DATA` polling), clamped ≤ deployed | | **PDFs edited** | cumulative `PDF_PROCESS` + `FILE_OPERATION` audit events that are **free UI runs** | ## Why the counting approach "Free operations = UI tool runs." Two dead ends first: - **Billing/PAYG is the wrong source** — it *deliberately discards* free ops (classified `BYPASSED`, no DB row); its tables only hold billable (API/AI/automation). - **Raw audit is also wrong** — a tool controller emits `PDF_PROCESS` for UI **and** API/AI/automation calls, and billable traffic exists on every tier. So the count is **audit filtered to free UI runs**. Audit events gain a `source` column, stamped from the always-on signal `BillingCategoryClassifier.classify(...) == BYPASSED` (not API-key auth, no `X-Stirling-Automation` header, not `/api/v1/ai/`) — zero billing-module coupling. Captured on the request thread (`AuditService.captureCurrentSource`), carried via MDC in `ControllerAuditAspect` (same propagation as `requestId`), persisted by `CustomAuditEventRepository`. The count filters `source = 'WEB'`. ## Endpoint `GET /api/v1/usage/fleet-stats` — admin-gated, EE-only. Returns `null` per field when EE auditing is off (→ N/A). ## Frontend - New `portal/api/fleetStats.ts` → `apiClient.local` (this instance's backend). - `FreePdfEditorsCard` rewired to `useAsync(fetchFleetStats)`; preview badge removed, `null`→"N/A", loading→"—". ## Tests `:proprietary:build` green — `FleetUsageControllerTest` (4) and `CustomAuditEventRepositoryTest` (+2 for source-from-MDC) pass; spotless clean. ## Notes / follow-ups - `deployed` currently counts all users incl. disabled — refine to enabled-only later. - **SaaS** (team-scoped endpoint + a `fleetStats.ts` override) is deferred to a follow-up riding the portal-SaaS layering PR #6900. - Depends on EE auditing running at `AuditLevel ≥ STANDARD` for the audit-derived figures; otherwise they show N/A.
