Every repository, service, Blazor page/dialog, and test now uses
async/await. Single atomic diff; the codebase does not compile in
intermediate states.
- BaseRepository: LoadListAsync/LoadAsync/SaveAsync return Task<T>;
per-file locks use SemaphoreSlim so waiters can await; Save
serialises to a MemoryStream sync (XmlSerializer has no async
form), then File.WriteAllBytesAsync + sync File.Move.
- RepositoryCache.GetOrLoadAsync takes a Func<Task<List<T>>>.
- All 7 repository interfaces + implementations async.
- All service interfaces + implementations async (except vendor
IFxService and stateless IFxConverter / SettingsService).
- Every Blazor OnInitializedAsync switches to await base.
- Test suite fully async, 42 tests pass.
AccountRepository.EnsureAccountsFile keeps two .GetAwaiter().GetResult()
bridges because it runs from the constructor.
Null-render guard follow-up (folded in):
Blazor now renders the component once with fields at their initial
values while OnInitializedAsync awaits — so fields declared `= null!`
are actually null on that first render and things like
`accounts.GroupBy(...)` throw ArgumentNullException. Fixed across
Transactions, BalanceReport, BalanceSheetReport, ProfitLossReport,
DetailReport, Assets, Spendings, SpendingsOverTime, TransactionDialog,
TransactionSplitDialog, and BookingRuleDialog:
- Collection fields initialise to [] so first-render loops are empty.
- Single-object data fields become nullable; the razor wraps
consumption in `@if (field is null) { <p>Lädt…</p> return; }`.
- <PlotlyChart> guarded behind a null check on config/layout/data so
Plotly.Blazor's @bind doesn't see nulls.
- Header/footer strings initialise to "" instead of null!.
Architectural hygiene on a single-user local Blazor Server app: the
observed win is one File.ReadAllBytesAsync and one
File.WriteAllBytesAsync per Load/Save, and after PR D each file is
loaded at most once per SignalR circuit.

Add ILogger<ViewService> and log the match-count summary at the end
of MatchOpenBankTransactions: "Matched {Matched} of {Total} open bank
transactions". Completes item 18.
Also drop the ISettingsService [Inject] from Home.razor.cs that was
declared but never referenced.

New IFxConverter.ConvertToChf(amount, fromCurrency) and FxConverter
wrap the vendor IFxService and the FixerIo API key so callers stop
threading the key through every conversion. ViewService drops
IFxService and ISettingsService from its constructor and takes
IFxConverter instead; GetAccountViewList and GetBalanceSheetView no
longer read settingsService.GetSettings() per method.
FxConverterTestShould locks in the target-currency + API-key routing.
40 tests total, all passing.

Add Schaad.Accounting.Tests (xUnit + NSubstitute + Shouldly, net9.0)
wired into Accounting.sln with a direct Reference to
Schaad.Finance.Api.dll so it flows into the test binary.
Naming convention: file/class is <Subject>TestShould, each test method
is DoThisWhenThat. Reads as a sentence:
"ViewService test should sum activa and passiva totals separately when
getting balance view". All assertions use Shouldly (.ShouldBe,
.ShouldBeNull, .ShouldContain, ...) rather than xUnit Assert.*.
38 tests across seven files:
- ViewServiceTestShould: balance math (activa/passiva totals, per-
account balance from start balance + credits - debits, FX conversion
to CHF) and bank-transaction auto-matching (booking-rule text,
value-matching preference, same-accounts-last-month fallback,
open-transaction filter).
- TransactionRepositoryTestShould: FX round-trip against a temp XML
directory, unknown-id -> null, and the mutation-on-read regression
from PR A (a second Get on the same FX transaction used to divide
by FxRate again).
- FormattingTestShould: Swiss thousands separator, two-decimal
rounding, culture independence.
- RepositoryCacheTestShould: loader called once, per-key isolation,
invalidation forces reload, case-insensitive keys.
- AccountRepositoryTestShould: id assignment, in-place update,
currency defaulting, delete, bank-account lookup, bank-balance
update, and constructor re-run against an existing file.
- ChartServiceTestShould: honours settingsService.GetYear() without
mutating it (locks in PR E), account vs sub-class grouping
heuristic, skips empty accounts.
- FileServiceTestShould: CSV header + running balance for debit and
credit lines, ordering by BookingDate/ValueDate/Value, no in-place
value mutation (locks in PR A).
CLAUDE.md gains a `dotnet test` line. IMPROVEMENT_PLAN.md notes that
this landed as three PRs (G, H, I) and was squashed on request.
Also add `*.DotSettings.user` to .gitignore so Rider's per-user
solution settings don't get accidentally staged.
