8080 is a very common, collision-prone port. 8760 (hours in a year) is an uncommon default that also avoids Home Assistant's 8123. Applied across Dockerfile (ASPNETCORE_URLS/EXPOSE), compose (mapping + healthcheck), the Unraid template, README and a code comment. The METERVAULT_PORT host override still works.

Complete the SDD §8 dashboard views that were deferred at the M5 boundary,
and fix a shipping bug that left the Docker demo empty.
Bug: "Load reference data" created meters/tank/tariffs but imported zero
readings in Docker. Root cause: sampledata/ was excluded by .dockerignore and
never copied into the build stage, so the App csproj's linked Content glob
resolved to nothing at publish time; ReferenceDataImporter then silently
skipped the missing CSVs after already writing its marker meter, leaving the
DB permanently "loaded" but empty.
- .dockerignore: stop excluding sampledata/
- Dockerfile: COPY sampledata/ into the build stage
- ReferenceDataImporter: fail-fast (validate CSVs exist before the marker
meter) and throw instead of silently skipping a missing file
- Program.cs + MeterVaultOptions: opt-in MeterVault__SeedReferenceData
(compose METERVAULT_SEED=true) for a one-command populated demo
New SDD §8 panels (read models in Infrastructure/Dashboard, Blazor pages):
- §8.4 Solar/PV (/solar): generation from GenerationCounter meters;
self-consumption / autarky % / self-consumption % / savings derived from
meters tagged total_load & grid_import via Meter.Meta role config
(MeterRoles/MeterMeta) — nothing hardcoded by name.
- §8.5 Oil/consumable (/consumables): tank level (cm→L calibrated), fill
gauge, deliveries log, burner runtime, effective L/h (fixed/empirical),
forecast-to-empty, tariff cost, monthly series.
- §8.6 Meter detail (/meters/{id}): raw readings, normalized consumption,
source status, tariff timeline, events, measured-vs-estimated markers.
- Reusable SeriesChart component; nav links; Meters list rows link to detail.
Tests: MeterMetaTests (Core, +10); DashboardRenderTests extended to assert the
three panel services compute real figures and the new routes render (108 total,
all green). Live-verified in Docker: seed imports 302 readings / 347 consumption
rows; panels render (generation 16,481 kWh, oil 3,967 L) cross-checking the DB.

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).

- PayloadExtractor: dot-path value/time extraction (Tasmota ENERGY.Total, bare scalars).
- MqttTopicMatcher: standard +/# wildcard matching.
- IngestionService: scale/offset, idempotent upsert on (meter_id, time), and a spurious-
decrease guard for monotonic registers (allowed only with a reset/swap event) + source
last-seen status.
- MqttMessageRouter + MqttIngestionWorker (MQTTnet 5): per-endpoint persistent connections,
topic subscription, graceful degradation; secrets resolved by env-var reference.
- Home Assistant: HaStateClient (REST /api/states parse) + HomeAssistantWorker polling on
each source's interval. HA-via-MQTT also works through the MQTT path.
- Ingestion workers gated by MeterVault:EnableLiveIngestion (off in tests).
85 tests green (53 Core + 32 integration): Tasmota payload → reading verified end to end.
Follow-up (polish): HA WebSocket push (state_changed) as an alternative to REST poll;
source-topic index caching in the router.
