Live ingestion wrote the raw reading and stopped there. Import, the REST push
endpoint and the meter editor all recompute afterwards; the MQTT/Tasmota/HA
path was the one that did not, so a polled reading landed in `reading` and
every derived figure stayed frozen at the last import. Observed on a
GenerationCounter: 45 readings, 44 consumption rows, generation pinned to the
register value of the last imported reading.
Recompute inline rather than behind a debounce. Normalizing a whole meter is
cheap at metering cadence and a background dirty-set worker is machinery this
does not yet need; the remark on RenormalizeAsync records when it would.
Fixes a latent bug this surfaced in NormalizationService: ExecuteDelete drops
the consumption rows in the database but leaves them in the change tracker, so
a second recompute on the same context threw an identity conflict on
(meter, time, kind). One worker scope ingesting two readings was enough to hit
it. Detach the stale entries after the delete.
Poll interval is now minutes, default 60, replacing seconds/60. A meter answers
"how much this month, what will it cost" — an hourly sample answers that
exactly as well as a per-second one, with far less raw volume (SDD §5.5). The
`pollSeconds` key no longer binds, so existing sources fall back to the 60
default and move from every-60-seconds to hourly, which is the intent. A source
that had deliberately set e.g. 300 seconds also lands on 60 minutes.
Two test cleanups now delete consumption before the meter: live ingestion never
produced any before, so the FK had nothing to trip on.

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.

- Minimal API under /api/v1 (SDD §9): POST /readings (idempotent HA push), GET /meters,
/energy-types, /consumption, /cost, /dashboard/summary, POST /events (records + recomputes),
GET+POST /tariffs, GET /sources/status.
- IngestionService.IngestByMeterAsync for direct REST push (batch-safe upsert via Local cache).
- ApiKeyFilter: X-Api-Key enforced against configured keys (open only when none set).
- ReverseProxyTrust middleware: adopt X-Forwarded-User/Remote-User behind Authelia/Traefik.
- Swagger/OpenAPI (Swashbuckle) at /swagger.
- Tests: push rejected without key (401), accepted + persisted with key; meters + swagger live.
94 tests green (56 Core + 38 integration).
