+# Quick 260723-lvg: "Jetzt abrufen"-Button für Ausschreibungs-Radar Summary
+
+Added a manual "Jetzt abrufen" poll trigger to the Ausschreibungs-Radar module,
+analogous to DKV's "Jetzt prüfen"/check-now. Backend: one admin-gated
+`POST /modules/tender-radar/poll-now` endpoint that runs
+`TenderIngestionService.pollDueSources()` immediately. Frontend: a
+`PollNowButton` in the tender-radar page header next to the settings gear,
+using the DKV spinner/disabled button pattern, refetching the result list on
+success via a `refreshKey` bump, with i18n error handling on failure.
+
+## Tasks Completed
+
+### Task 1: Backend admin-gated POST /poll-now endpoint + controller spec
+- Injected `TenderIngestionService` as the LAST constructor param on
+  `TendersController` (declared optional `?:` in TypeScript so all 7-arg
+  existing spec call sites still type-check; NestJS DI always resolves it
+  in production since it's already a provider in `tenders.module.ts`).
+- Added `pollNow()` handler: `@Post('poll-now')`, `@Roles(Role.ADMIN,
+  Role.SUPER_ADMIN)`, declared immediately after `getSourceConfig()` — well
+  before `@Get(':id')` (route-order Pitfall 5). Body: awaits
+  `pollDueSources()`, returns `{ ok: true }`. No try/catch — the service
+  never throws (catch-and-log per tick + per source).
+- Added `makeFakeIngestionService()` helper + a new describe block asserting
+  delegation, return shape, and `@Roles` metadata via
+  `Reflect.getMetadata(ROLES_KEY, TendersController.prototype.pollNow)`.
+- Added a route-declaration-order regression test (`pollNow` index <
+  `getTender` index) to the existing "route declaration order" describe
+  block.
+- Commit: `7502f97`
+
+### Task 2: Frontend PollNowButton, pollNow client, refetch wiring + i18n
+- `pollNow()` client in `tender-radar-api.ts` — `POST
+  /modules/tender-radar/poll-now`, `credentials: 'include'`, throws on
+  non-2xx, mirrors DKV's `checkNow` client shape.
+- New `PollNowButton.tsx` (self-contained, `'use client'`): copies the DKV
+  `SpinnerIcon`, renders the primary button with the DKV opacity/disabled
+  states, shows a dismissible destructive-text error line on failure. Props:
+  `{ onPolled?: () => void }`.
+- `page.tsx`: added `refreshKey` state, wrapped the settings gear `<Link>`
+  and `<PollNowButton onPolled={...}>` in a right-side flex cluster inside
+  the existing header row, passed `refreshKey` into `<ResultsList>`.
+- `ResultsList.tsx`: accepts an optional `refreshKey` prop
+  (`{ refreshKey = 0 }: { refreshKey?: number } = {}`), added to the `load`
+  `useCallback` dependency array alongside `paramsKey`.
+- `de.json`/`en.json`: added `tenderRadar.page.pollNow`, `pollNowTitle`,
+  `polling`, `pollError`, `pollErrorDismiss` to both locales (parity spec
+  green).
+- New `PollNowButton.test.tsx`: render/label test, click→pollNow→onPolled
+  test, pending-spinner/disabled test (deferred promise), rejection→error
+  copy→no-onPolled test.
+- Commit: `bdaf154`
+
+## Semantic Honesty
+
+No `force` parameter was added to `pollDueSources()` — out of scope per the
+plan. The button labels honestly communicate "fällige Quellen jetzt abrufen"
+(fetch DUE sources now): `pollNowTitle` / EN `Fetch due sources now`. A
+`'day'`-granularity source (e.g. `doe-opendata`) that already ingested
+today's batch is a structural no-op on this click, by design.
+
+## Deviations from Plan
+
+### Auto-fixed Issues
+
+**1. [Rule 3 - Blocking issue] Made `tenderIngestionService` constructor param optional**
+- **Found during:** Task 1, `npx tsc --noEmit` after the vitest run passed
+- **Issue:** The plan's approach of appending `TenderIngestionService` as a
+  required (non-optional) 8th constructor param compiles fine at the type
+  level for new call sites, but breaks TypeScript compilation for every
+  pre-existing 7-arg `new TendersController(...)` call in
+  `tenders.controller.spec.ts` (36 call sites) — vitest itself doesn't type-check
+  so the test run was green, but `tsc --noEmit` caught it (`TS2554: Expected
+  8 arguments, but got 7`).
+- **Fix:** Declared the param optional (`tenderIngestionService?:
+  TenderIngestionService`) and used a non-null assertion (`this
+  .tenderIngestionService!.pollDueSources()`) inside `pollNow()` — safe
+  because NestJS DI always resolves and injects this provider in production
+  (already registered in `tenders.module.ts`); only unit tests that never
+  call `pollNow()` omit it.
+- **Files modified:** `apps/api/src/tenders/tenders.controller.ts`
+- **Commit:** `7502f97`
+
+No other deviations — plan executed as written otherwise.
+
+## Test Results
+
+- API: `cd apps/api && npx vitest run` → 393/393 passed (was 390/390; +3 new:
+  delegation, roles metadata, route-order guard).
+- API: `cd apps/api && npx tsc --noEmit -p tsconfig.json` → clean.
+- Web: `cd apps/web && npx vitest run` → 155/155 passed (was 151/151; +4 new
+  PollNowButton tests).
+- Web: `cd apps/web && npx tsc --noEmit` → clean.
+- Targeted verify command (`PollNowButton.test.tsx` + `ResultsList.test.tsx`
+  + `tenderRadar-parity.spec.ts`): 15/15 passed.
+
+## Known Stubs
+
+None.
+
+## Threat Flags
+
+None beyond the plan's own threat register (T-lvg-01/02/03), which is fully
+addressed: `@Roles(ADMIN, SUPER_ADMIN)` gates the new route, no per-body
+privilege input, generic i18n error copy on 403.
