Summary

GET /qr — Czech QR Platba PNG endpoint; ports Python's qr_code() exactly: account validation (^[A-Z]{2}\d{2,34}$|^\d{1,16}/\d{4}$), amount clamping [0, 10M], * stripping, SPD string format. New dep: github.com/skip2/go-qrcode.
GET /sync-bank — runs Fio sync → infer payments for the current year, captures output into the sync.tmpl page with a success/error banner. Wired via web.ActionHandlers{BankSync} closure in serverCmd, which also calls FlushCache after a successful run.
GET /flush-cache + POST /flush-cache — confirmation form (GET) + action (POST) that deletes cache files and shows the deleted count.
GET /version — JSON alias of /api/version (Python parity; same {tag, commit, build_date} shape).
FlushCache() (int, error) added to membership.Sources interface; implemented on realSources via cache.FileCache.Flush(); stubbed on all test fakes.
15 new tests: TestQRBuildSPD (9 table cases), TestServeQR, TestServeFlushCacheGET, TestServeFlushCachePOST, TestServeSync, TestServeVersion.

Test plan

cd go && go test ./... — all green
go run ./cmd/fuj server → open http://localhost:8080
/adults → click Pay on an unpaid month → modal shows QR image; scan with a Czech banking app
Direct: /qr?account=2702008874/2010&amount=700&message=Test → PNG renders
Nav → Sync Bank Data → page shows captured log + green banner
Nav → Flush Cache → button → success banner with file count
/version in browser → JSON {tag, commit, build_date}
/api/version still returns identical JSON (parity check)
Adults / juniors / payments still render without regressions

## Summary - **`GET /qr`** — Czech QR Platba PNG endpoint; ports Python's `qr_code()` exactly: account validation (`^[A-Z]{2}\d{2,34}$|^\d{1,16}/\d{4}$`), amount clamping `[0, 10M]`, `*` stripping, SPD string format. New dep: `github.com/skip2/go-qrcode`. - **`GET /sync-bank`** — runs Fio sync → infer payments for the current year, captures output into the `sync.tmpl` page with a success/error banner. Wired via `web.ActionHandlers{BankSync}` closure in `serverCmd`, which also calls `FlushCache` after a successful run. - **`GET /flush-cache` + `POST /flush-cache`** — confirmation form (GET) + action (POST) that deletes cache files and shows the deleted count. - **`GET /version`** — JSON alias of `/api/version` (Python parity; same `{tag, commit, build_date}` shape). - **`FlushCache() (int, error)`** added to `membership.Sources` interface; implemented on `realSources` via `cache.FileCache.Flush()`; stubbed on all test fakes. - **15 new tests**: `TestQRBuildSPD` (9 table cases), `TestServeQR`, `TestServeFlushCacheGET`, `TestServeFlushCachePOST`, `TestServeSync`, `TestServeVersion`. ## Test plan - [ ] `cd go && go test ./...` — all green - [ ] `go run ./cmd/fuj server` → open http://localhost:8080 - [ ] `/adults` → click **Pay** on an unpaid month → modal shows QR image; scan with a Czech banking app - [ ] Direct: `/qr?account=2702008874/2010&amount=700&message=Test` → PNG renders - [ ] Nav → **Sync Bank Data** → page shows captured log + green banner - [ ] Nav → **Flush Cache** → button → success banner with file count - [ ] `/version` in browser → JSON `{tag, commit, build_date}` - [ ] `/api/version` still returns identical JSON (parity check) - [ ] Adults / juniors / payments still render without regressions 🤖 Generated with [Claude Code](https://claude.com/claude-code)
