Editing a meter (any admin dialog, select dropdown, snackbar, dark-mode toggle)
did nothing: pages declared @rendermode InteractiveServer individually, but
MainLayout — which hosts MudDialogProvider/MudPopoverProvider/MudSnackbarProvider
— was rendered by <Routes>, which was static. Inline MudDialogs and MudSelect
popovers render through those providers, so with the providers non-interactive no
dialog could ever open.
Set the render mode on <Routes> and <HeadOutlet> in App.razor (global
interactivity) and removed the now-redundant per-page @rendermode declarations
(they would otherwise throw "parent already has a render mode").
Why it slipped through: the integration render tests only issue a GET (static
prerender), which never exercises the SignalR circuit. Verified this fix with a
real headless-browser run (Playwright): the meter edit dialog opens and the
"Sub-meter of (upstream meters)" multi-select opens with options — proving the
layout providers are now interactive. 116 tests still green.

Three requested phases.
1) Admin section (SDD §8.7) — MudBlazor inline-dialog CRUD, consistent pattern,
delete guards, snackbar feedback, shared Confirm helper:
- Energy types: create/edit/delete (blocks delete when meters reference it).
- Meters: create/edit/delete; recomputes consumption when mode/baseline
changes (NormalizationService over a fresh factory context, in a tx);
delete cascades data (consumption+readings are Restrict → removed first).
- A meter's ingest sources: manage on the meter-detail Sources tab
(add/edit/delete MQTT/Tasmota/HA sources with typed config).
- Tariffs: full CRUD (scope/component/value/validity).
- Cost categories: CRUD + member management (meter or energy-type members).
- Connectors: ingestion_endpoint CRUD (MQTT broker + Home Assistant);
secrets referenced by env-var name only, never stored.
- Settings: read-only effective-config view (settings are env-driven and
reproducible, so an editable form would change nothing — kept honest).
PV role is now editable on meters (MeterMeta.SetRole can clear a role).
2) Read Home Assistant — extracted a shared public HaEndpointConfig (was a
private record in the worker), added HaConnectionTester (powers the connector
"Test connection": checks base URL + env-resolved token, optionally reads one
entity). Configuring an HA connector + an HA source on a meter drives the
existing REST-poll worker end to end. (WebSocket push stays a future
optimization; REST poll already reads HA.)
3) Wiring/placeholder audit — swept every OnClick/Href: all handlers are real,
all internal links resolve to real routes, no TODO/stub/placeholder code.
Fixed one genuine gap: MainLayout had no drawer toggle, so the nav was
unreachable on narrow screens — added a hamburger button.
Tests: +6 (MeterMeta.SetRole role-removal; HaConnectionTester fail-closed
guard branches with a throwing HttpClientFactory proving no network on bad
config); render test now covers all admin routes. 69 Core + 45 Integration =
114 green. Live-verified in Docker: all admin pages 200, drawer toggle present,
Settings shows real effective config.

Correctness/data:
- Fix demo cost double-count: reference importer no longer imports the Kosten Strom/Wasser
columns for categories that are metered (only Heizung), so Wasser rollup is 70€ not 140€.
- Spurious-decrease guard: only a reset/swap in the window (prevReading, thisReading] explains
a decrease — an old historical reset no longer permanently disables the guard.
- Gate swap auto-detection on MappingProfile.DetectCumulativeSwaps (flag was ignored).
- Prorate basePrice by bucket length (day/month/year); guard virtual expressions against NaN/Inf.
Concurrency/infra:
- Blazor: register a DbContextFactory; CostService/DashboardService and the read pages now use
short-lived per-operation contexts (no shared circuit DbContext); guard Trends re-entrancy.
- /events: wrap event insert + consumption recompute in one transaction (atomic); 404 (not 500)
on unknown meter.
- MQTT worker: subscribe to newly-added topics on each tick; move client cleanup into finally.
- Migrations: CREATE MATERIALIZED VIEW IF NOT EXISTS + if_not_exists on CAgg/compression/
hypertable calls (re-run-safe after a mid-migration crash).
- HA worker: prune stale poll-schedule entries; export: null dangling ImportBatchIds on restore.
API/security:
- API fail-closed by default: with no keys and AllowAnonymousApi off, /api/v1 returns 401
(protects /export and /import). New MeterVault:AllowAnonymousApi opt-in.
- Cap /readings batch at 5000; report ignored (unknown-meter) count; enums as strings in JSON.
+4 regression tests (guard window, API closed, /events 404, no demo double-count). 98 tests
green; Docker deploy re-verified healthy with the API fail-closed.
