## 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.
Frontend
All frontend commands are run from the repository root using Task:
task frontend:dev— start Vite dev server (localhost:5173)task frontend:build— production buildtask frontend:test— run teststask frontend:test:watch— run tests in watch modetask frontend:lint— run ESLint + cycle detectiontask frontend:typecheck— run TypeScript type checkingtask frontend:check— run typecheck + lint + testtask frontend:install— install npm dependencies
For desktop app development, see the Tauri section below.
Layout
frontend/ is a workspace containing one or more apps. Today it holds the
PDF editor under frontend/editor/; new apps (the developer portal, etc.)
will sit alongside it as siblings. Shared tooling — package.json, node_modules,
.storybook/, ESLint, Prettier — lives at frontend/ so every app installs
once and lints with the same config.
Environment Variables
The editor's environment variables live in committed .env files at
frontend/editor/:
.env— used by all builds (core, proprietary, and as the base for desktop/SaaS).env.desktop— additional vars loaded in desktop (Tauri) mode.env.saas— additional vars loaded in SaaS mode
These files contain non-secret defaults and are checked into Git, so most dev work needs no further setup.
To override values locally (API keys, machine-specific settings), create an uncommitted sibling editor/.env.local / editor/.env.desktop.local / editor/.env.saas.local. Vite automatically layers these on top of the committed files.
Docker Setup
For Docker deployments and configuration, see the Docker README.
Tauri
All desktop tasks are available via Task. From the root of the repo:
Dev
task desktop:dev
This ensures the JLink runtime and backend JAR exist (skipping if already built), then starts Tauri in dev mode.
Build
task desktop:build
This does a full clean rebuild of the backend JAR and JLink runtime, then builds the Tauri app for production.
Platform-specific dev builds are also available:
task desktop:build:dev # No bundling
task desktop:build:dev:mac # macOS .app bundle
task desktop:build:dev:windows # Windows NSIS installer
task desktop:build:dev:linux # Linux AppImage
JLink Tasks
You can also run JLink steps individually:
task desktop:jlink # Build JAR + create JLink runtime
task desktop:jlink:jar # Build backend JAR only
task desktop:jlink:runtime # Create JLink custom JRE only
task desktop:jlink:clean # Remove JLink artifacts
Clean
task desktop:clean
Removes all desktop build artifacts including JLink runtime, bundled JARs, Cargo build, and dist/build directories.
