Stratara.ServiceDefaults
Derived. The behaviour described here is specified under
openspec/specs/. Those specifications are the source; this page explains and illustrates them.
License: MIT.
Cross-host observability defaults for the Stratara stack. Reference from every host (API, worker) to get OpenTelemetry + Serilog wired up with sensible defaults.
What's in the box
| Extension | Purpose |
|---|---|
ConfigureOpenTelemetry |
Logging + metrics + tracing with HTTP, EF Core, RabbitMQ, runtime instrumentation; OTLP exporter wired up automatically when OTEL_EXPORTER_OTLP_ENDPOINT is set. Accepts optional MeterProviderBuilder / TracerProviderBuilder callbacks for host-specific extras. |
ConfigureSerilog |
Structured logging with destructuring attributes, async console sink, OTLP sink (gRPC or HTTP/Protobuf based on OTEL_EXPORTER_OTLP_PROTOCOL), dev-mode log cleanup at {Path.GetTempPath()}/stratara-logs/{service-name}.log — the OS temp directory, so not literally /tmp on Windows or macOS. |
ConfigureSerilogBootstrapLogger |
Sets up Log.Logger as a bootstrap logger before the host is built, so early-startup errors surface to the console. |
Quick start
builder.ConfigureOpenTelemetry();
builder.ConfigureSerilog();
It deletes your development log file on start-up
In the Development environment only, configuring Serilog deletes the current log file before
opening it: %TEMP%/stratara-logs/{OTEL_SERVICE_NAME}.log, where the service name falls back to
Unknown when OTEL_SERVICE_NAME is unset. The intent is a clean file per debugging session rather
than one that grows across dozens of restarts.
Two consequences worth knowing before they cost you an hour:
- A crash you wanted to read is gone the moment you restart to reproduce it. Copy the file before restarting, or point the sink elsewhere for that session.
- Two development services with no
OTEL_SERVICE_NAMEshareUnknown.logand delete each other's. Set the variable per service.
Outside Development nothing is deleted.

Prerelease dependencies. This package transitively pulls in two prerelease OpenTelemetry instrumentation packages that have no stable release yet:
OpenTelemetry.Instrumentation.EntityFrameworkCore(beta) andRabbitMQ.Client.OpenTelemetry(RC). Both ride the stable OpenTelemetry 1.15.x core. NU5104 is suppressed in this csproj with that justification — consumers inherit the prerelease deps transitively. We will swap to GA as soon as the vendors ship stable.

A release for one person who belongs to several tenants — and, sharing one identity store, to several applications.
### Added
- **`MembershipStatus.Former`** records a member who has left. It confers nothing — no role, permission or
cross-tenant access, never the tenant at sign-in, never a selection — and stays listed until the user's or the
tenant's erasure removes it.
- **`AddCheckedMembershipTenantClaim<TUser>()`**, a third tenant-claim mode: the claim is stamped at sign-in, kept when
the security-stamp validator refreshes a cookie sign-in, and checked on every request. A request whose user is no
longer an active member of the carried tenant loses the claim and resolves to the reserved default tenant, without
another tenant substituted. Only principals ASP.NET Identity issued are checked; an API key or a token the host
mints keeps its tenant. The tenant changes only when the host re-issues the sign-in. Combining it with
`AddMembershipTenantClaimsTransformation()` throws, and a claims transformation of the host's own registered
beside it is refused at start. Use it where several applications share one identity store:
`active_tenant` holds one selection per account, so live resolution moves every open session when any of them
switches.
- **`EventSubject.ForUser(userId)`** and **`EventSubject.NamesAnOwner`**: a stream can be created for a user alone,
for data that belongs to a person rather than to any of their tenants. It is recorded under the reserved default
tenant, keeps that owner for every later event whatever tenant the session names, and its encrypted fields — at
every level — are keyed to the person: shredded by the person's erasure, untouched by any tenant's.
`KeySubject.User` covers those keys too, so nothing is encrypted for the person again after the erasure.
- **`StrataraIdentityStore`, an identity store several hosts can share on PostgreSQL**, with its migrations shipped
in `Stratara.EventSourcing.EntityFrameworkCore`. It holds ASP.NET Identity's tables, passkeys included, and the
tenant directory in the fixed schema `stratara_identity`, with the history in
`stratara_identity.__stratara_identity_migrations`. `AddStrataraIdentityStore()` registers it on the connection
string `identitydb` (falling back to `defaultdb`, never through a tenant-routing `IDbResolver`) with the
directory's stores over it, and refuses a host that turns on `Stores.ProtectPersonalData`;
`MigrateStrataraIdentityStoreAsync()` creates the database where needed and applies the migrations — hosts that
migrate at once take turns. The account type is `IdentityUser` and cannot be extended, and the store fixes the
ASP.NET Identity schema version and key lengths, so every host's model matches the shipped migrations. Within a
major version the schema changes only additively. Moving an existing identity store onto it means replacing it and
seeding with the same user and tenant ids; the new guide *Shared Identity Store* describes it.
### Changed
- **Setting a membership to a status other than `Active` clears a selection that pointed at it**, as removing it
already did.
- **An explicit subject that names a user and no tenant is accepted** by `AppendOnBehalfOfAsync` and
`CreateOnBehalfOfAsync`; one that names neither is refused as before. A session whose tenant resolved to the
reserved default still gives an event no owner.
- **BREAKING (behaviour): an event or aggregate type marked `[EncryptData]` as a whole stops the host from starting.**
`EncryptionMetadataDriftGuard` refuses every registered aggregate, and every event type a registered aggregate
applies, that carries the attribute on the type; an event type no aggregate applies is refused when it is appended,
before anything is written. Once its subject was erased such a payload had nothing left to deliver, and a replay or
rebuild stopped there for good. Mark the properties instead; payloads already written as a whole are still read.
Commands and other types may still be marked as a whole.
### Fixed
- **A user's erasure shreds their own data through a key store that cannot list its scopes.** The eraser names the
user's keys under the reserved default tenant itself, at every level; until now only a listing reached the
user-level one.
