Complete legacy-credits teardown ("Group 3"). The per-user/per-team
credit model is fully superseded by PAYG (`wallet_ledger`) — confirmed
no PAYG code references it. Authorized to also remove the `TeamCredit`
pool + its monthly reset.
## Frontend (saas)
- Deleted `saas/hooks/useCredits.ts`, `apiKeys/hooks/useCredits.ts`,
`types/credits.ts`, `apiKeys/UsageSection.tsx`.
- `UseSession.tsx`: removed credit members (`creditBalance`,
`creditSummary`, `hasSufficientCredits`, `updateCredits`,
`refreshCredits`, `fetchCredits`) + the credit types + global
credit-update callback. **Kept** `isPro`/`refreshProStatus` and the
Supabase auth subscription listener.
- `services/apiClient.ts`: removed the dead `x-credits-remaining`
handler + low-credit plumbing (token-refresh / PAYG / 401 logic
untouched).
- Credit refs removed from `ApiKeys.tsx`, `AppConfigModal.tsx`,
`auth/teamSession.ts`.
## Java (:saas)
**Deleted (15):** `UserCredit`(+repo),
`TeamCredit`(+repo)+`TeamCreditService`, `CreditService`,
`CreditHeaderUtils`, `CreditResetScheduler`, `CreditController`,
`CreditInterceptorConfig`, `UnifiedCreditInterceptor`,
`CreditSuccessAdvice`, `CreditErrorAdvice`, `CreditConsumptionResult` (+
the CreditController test).
**Edited — stripped legacy credit side-effects, preserved
auth/role/AI/PAYG logic:**
- `AiCreate`/`AiProxyController`: dropped the
`X-Credits-Remaining`/`X-Credit-Source` response header (its only
consumer, the desktop credit system, was already removed).
- `SaasTeamService`: dropped UserCredit/TeamCredit init on team-create +
seat-update.
- `SupabaseAuthenticationFilter` / `SupabaseSecurityConfig`: dropped
`getOrCreateUserCredits` on signup + the credit field/CORS header.
- `UserRoleService`: dropped `resetCycleAllocationForRoleChange`;
`ROLE_PRO_USER` grant/revoke preserved.
- proprietary `UserRepository`: dropped
`findUsersWithApiKeyButNoCredits()`.
- Tests updated to drop credit mocks/refs.
## Kept / scope
- `isPro` / `is_pro` RPC / `ROLE_PRO_USER` (that's the separate Group-4
/ EE effort) and **all PAYG** are untouched.
- **No DB tables dropped.** `user_credits`/`team_credits` stay until a
later **gated** migration — which this PR unblocks (the JPA entities
that pinned them are gone).
## Verify
`:saas:compileJava` + `:saas:compileTestJava` pass; FE `tsc --noEmit`
(saas) + eslint clean; 0 stray artifacts; no residual source refs to the
deleted classes.
## Follow-up (not in this PR)
`ErrorTrackingService` (+
`UserErrorTracker`/`ProcessingErrorType`/`CreditsProperties`) is now a
dead island — its only callers were the deleted interceptors. Safe to
delete, but it cascades beyond the credit scope, so it's a separate
tidy-up.

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.
