Inbound-API bearer credentials are no longer persisted in plaintext. ApiKey now
holds a KeyHash (peppered HMAC-SHA256); the key is shown once at creation and
only its hash is stored. Lookup and validation hash the presented candidate.
Cross-module: Commons (ApiKey, ApiKeyHasher), ConfigurationDatabase (mapping +
HashApiKeyValue migration), InboundAPI (ApiKeyValidator), ManagementService
(key creation), CentralUI (ApiKeys.razor). Existing keys must be re-issued.
Adds a new HiLo alarm trigger type with four configurable setpoints
(LoLo / Lo / Hi / HiHi). Each setpoint carries an optional priority,
deadband (for hysteresis), and operator message. The site runtime emits
AlarmStateChanged with an AlarmLevel field so consumers can differentiate
warning vs critical bands.
Plumbing:
- new AlarmLevel enum + AlarmStateChanged.Level/Message init properties
- AlarmTriggerEditor (Blazor) gets a HiLo render with severity tinting
- AlarmTriggerConfigCodec extracted from the editor for testability
- sitestream.proto carries level + message over gRPC
- SemanticValidator enforces numeric attribute, setpoint ordering,
non-negative deadband
- on-trigger scripts get an Alarm global (Name/Level/Priority/Message)
so notification routing can branch by severity
- per-instance InstanceAlarmOverride entity + EF migration + flattening
step + CLI commands; HiLo overrides merge setpoint-by-setpoint, binary
types whole-replace
- DebugView shows a Level badge + per-band message tooltip
- App.razor auto-reloads on permanent Blazor circuit failure
- docker/regen-proto.sh automates the proto regen workflow (the linux/arm64
protoc segfault means generated files are checked in for now)
Adds 11 new tests covering:
- Roundtrip of DiscardOldest/SubscriptionPriority/SubscriptionDisplayName/TimestampsToReturn
- Roundtrip of UserIdentity sub-object across all three TokenTypes
- Roundtrip of Deadband sub-object
- ToFlatDict/FromFlatDict for UserIdentity.* and Deadband.* dotted keys
- Validator rules: empty SubscriptionDisplayName, UsernamePassword w/o Username,
X509 w/o CertificatePath, Deadband Value <= 0, prefix propagation
Build passes; tests fail because serializer/validator have not been extended yet
(TDD red phase). Task B2 will implement the changes to drive them green.
Composable StaleTagMonitor class in Commons fires a Stale event when no
value is received within a configurable max silence period. Integrated
into both LmxProxyDataConnection and OpcUaDataConnection adapters via
optional HeartbeatTagPath/HeartbeatMaxSilence connection config keys.
When stale, the adapter fires Disconnected triggering the standard
reconnect cycle. 10 unit tests cover timer behavior.
Replace raw dictionary casting with ScriptParameters wrapper that provides
Get<T>, Get<T?>, Get<T[]>, and Get<List<T>> with clear error messages,
numeric conversion, and JsonElement support for Inbound API parameters.
