- Notification hook contract (`exception.*` events) and rate-limit policy.
- Sample payloads for each state and error cases.
## Draft sample (placeholder)
- See `docs/api/console/samples/exception-schema-sample.json` for a skeleton payload covering `pending_review` state.
- Replace with authoritative samples once schema is published.
## TODO
- Replace with ratified schema + samples; log hash/date; link from Web I/II sprint logs.

> Until backend implementations ship, use the examples above to unblock DOCS-AIAI-31-004; replace them with live captures once the gateway endpoints are available in staging.
## Exports (draft contract)
Routes
- `POST /console/exports` — start an evidence bundle export job.
- `GET /console/exports/{exportId}` — fetch job status and download locations.
- `GET /console/exports/{exportId}/events` — SSE stream of job progress (optional).
Headers
- `Authorization: Bearer <token>`
- `X-StellaOps-Tenant: <tenantId>`
- `Idempotency-Key: <uuid>` (recommended for POST)
- `Accept: application/json` (status) or `text/event-stream` (events)
Request body (POST /console/exports)
- `scope`: `{ tenantId, projectId? }`
- `sources`: array of `{ type: "advisory"|"vex"|"policy"|"scan", ids: string[] }`
- `formats`: array of `"json"|"csv"|"ndjson"|"pdf"`
- `attestations`: `{ include: boolean, sigstoreBundle?: boolean }`

- **Wave C (signals/VEX Lens):** Tasks 8, 13 DONE; task 10 (signals) now TODO (SIGNALS-24-002 resolved 2025-12-06). Only task 11 (backfill) remains BLOCKED.
- Waves stay serialized A → B → C to avoid contract drift; no new DOING items until blockers clear.

- Excititor remains aggregation-only: policy lookup returns stored scope/linkset metadata without verdicts.

- Risk feed (EXCITITOR-RISK-66-001) implemented with zero derived severity per AOC baseline.
- Orchestrator integration delivered; keep feature-flagged until production thresholds validated.
## Next Checkpoints
- Publish Risk feed envelope to unblock EXCITITOR-RISK-66-001.
- Sprint 0122 COMPLETE: All tasks delivered.
- Re-run WebService tests after any advisory_key schema changes from Policy.
- Validate timeline/locker/attestation events with latest Evidence Locker manifests to ensure parity.
@@ -56,10 +57,10 @@
- **Decisions**
- Aggregation-only stance holds for policy/risk APIs; no consensus or severity derivation.
- Worker orchestration stays feature-flagged; falls back to local mode if orchestrator unavailable.
- Risk feed implemented with `/risk/v1/feed` endpoints; status/justification/provenance only.
- **Risks & Mitigations**
- Policy contract delays block API shape → Keep tasks BLOCKED; proceed once contract lands; reuse Concelier/Vuln canonicalization if applicable.
- Risk feed envelope unknown → Mirror Risk Engine schema as soon as published; stage behind feature flag.
- Policy endpoints test harness injects stub signer/attestation services; test is active and passing (no skips remaining).
- Risk feed uses linkset data directly; no additional storage required.
## Next Checkpoints
- Await Policy/Risk contract publication; unblock POLICY-20-001/002 and RISK-66-001 upon receipt.
- Sprint 0122 COMPLETE: All tasks DONE.

## Decisions & Risks
- Cleanup is strictly after all phases complete; do not start T7 tasks until module cutovers are DONE.
- Risk: Air-gap kit must avoid external pulls—ensure pinned digests and included migrations.
- BLOCKER: Concelier has pervasive Mongo references (connectors, exporters, tests, docs). Requires phased refactor plan (PG-T7.1.PLAN) before deletion to avoid breaking build.
- BLOCKER: Scheduler: Postgres equivalent for GraphJobStore/PolicyRunService not designed; need schema/contract decision to proceed with PG-T7.1.2a and related deletions.
- BLOCKER: Scheduler Worker still depends on Mongo-era repositories (run/schedule/impact/policy); Postgres counterparts are missing, keeping solution/tests red until implemented or shims added.
- BLOCKER: `StellaOps.Concelier.Storage.Mongo` project missing; Concelier connectors/tests fail compilation during scheduler builds/tests until a Postgres replacement or compatibility shim lands.
- BLOCKER: Scheduler/Notify/Policy/Excititor Mongo removals must align with the phased plan; delete only after replacements are in place.

# Sprint 7000-0001-0001 · Router Foundation · Project Skeleton
## Topic & Scope
Phase 1 of Router implementation: establish the project skeleton with all required directories, solution files, and empty stubs. This sprint creates the structural foundation that all subsequent router sprints depend on.
**Goal:** Get a clean, compiling skeleton in place that matches the spec and folder conventions, with zero real logic and minimal dependencies.
**Working directories:**
- `src/__Libraries/StellaOps.Router.Common/`
- `src/__Libraries/StellaOps.Router.Config/`
- `src/__Libraries/StellaOps.Microservice/`
- `src/__Libraries/StellaOps.Microservice.SourceGen/`
- `src/Gateway/StellaOps.Gateway.WebService/`
- `tests/StellaOps.Router.Common.Tests/`
- `tests/StellaOps.Gateway.WebService.Tests/`
- `tests/StellaOps.Microservice.Tests/`
**Isolation strategy:** Router uses a separate `StellaOps.Router.sln` solution file to enable fully independent building and testing. This prevents any impact on the main `StellaOps.sln` until the migration phase.
## Dependencies & Concurrency
- **Upstream:** None. This is the first router sprint.
- **Downstream:** All other router sprints depend on this skeleton.
- **Parallel work:** None possible until this sprint completes.
- **Cross-module impact:** None. All work is in new directories.
## Documentation Prerequisites
- `docs/router/specs.md` (canonical specification - READ FIRST)
- `docs/router/implplan.md` (implementation plan overview)
- `docs/router/01-Step.md` (detailed task breakdown for this sprint)
> **BLOCKED Tasks:** Before working on BLOCKED tasks, review [../implplan/BLOCKED_DEPENDENCY_TREE.md](../implplan/BLOCKED_DEPENDENCY_TREE.md) for root blockers and dependencies.
## Invariants (from specs.md)
Before coding, acknowledge these non-negotiables:
- Method + Path identity for endpoints
- Strict semver for versions
- Region from `GatewayNodeConfig.Region` (no host/header derivation)
- No HTTP transport for microservice-to-router communications
- Single connection carrying HELLO + HEARTBEAT + REQUEST/RESPONSE + CANCEL
- Router treats body as opaque bytes/streams
- `RequiringClaims` replaces any form of `AllowedRoles`

## Project Reference Graph
```
StellaOps.Gateway.WebService
├── StellaOps.Router.Common
└── StellaOps.Router.Config
└── StellaOps.Router.Common
StellaOps.Microservice
└── StellaOps.Router.Common
StellaOps.Microservice.SourceGen
(no references yet - stub only)
Test projects reference their corresponding main projects.
```
## Stub Types to Create
### StellaOps.Router.Common
- Enums: `TransportType`, `FrameType`, `InstanceHealthStatus`
- Models: `ClaimRequirement`, `EndpointDescriptor`, `InstanceDescriptor`, `ConnectionState`, `Frame`
- Interfaces: `IGlobalRoutingState`, `IRoutingPlugin`, `ITransportServer`, `ITransportClient`
### StellaOps.Router.Config
- `RouterConfig`, `ServiceConfig`, `PayloadLimits` (property-only classes)
### StellaOps.Microservice
- `StellaMicroserviceOptions`, `RouterEndpointConfig`
- `ServiceCollectionExtensions.AddStellaMicroservice()` (empty body)
### StellaOps.Gateway.WebService
- `GatewayNodeConfig` with Region, NodeId, Environment
- Minimal `Program.cs` that builds and runs (no logic)
## Exit Criteria
Before marking this sprint DONE:
1. [x] `dotnet build StellaOps.Router.slnx` succeeds with zero warnings
2. [x] `dotnet test StellaOps.Router.slnx` passes (even with dummy tests)
3. [x] All project names match spec: `StellaOps.Gateway.WebService`, `StellaOps.Router.Common`, `StellaOps.Router.Config`, `StellaOps.Microservice`
4. [x] No real business logic exists (no transport logic, no routing decisions, no YAML parsing)
5. [x] `docs/router/README.md` exists and points to `specs.md`
## Execution Log
| Date (UTC) | Update | Owner |
|------------|--------|-------|
| 2024-12-04 | Sprint completed: all skeleton projects created, build and tests passing | Claude |
## Decisions & Risks
- Router uses a separate solution file (`StellaOps.Router.sln`) to enable isolated development. This will be merged into main `StellaOps.sln` during the migration phase.
- Target framework is `net10.0` to match the rest of StellaOps.
- `StellaOps.Microservice.SourceGen` is created as a plain classlib for now; it will be converted to a Source Generator project in a later sprint.

# Sprint 7000-0001-0002 · Router Foundation · Common Library Models
## Topic & Scope
Phase 2 of Router implementation: implement the shared core model in `StellaOps.Router.Common`. This sprint makes Common the single, stable contract layer that Gateway, Microservice SDK, and transports all depend on.
**Goal:** Lock down the domain vocabulary. Implement all data types and interfaces with **no behavior** - just shapes that match `specs.md`.
**Working directory:** `src/__Libraries/StellaOps.Router.Common/`
**Key principle:** Changes to `StellaOps.Router.Common` after this sprint must be rare and reviewed. Everything else depends on it.
## Dependencies & Concurrency
- **Upstream:** SPRINT_7000_0001_0001 (skeleton must be complete)
- **Downstream:** All other router sprints depend on these contracts
- **Parallel work:** None possible until this sprint completes
- **Cross-module impact:** None. All work is in `StellaOps.Router.Common`
## Documentation Prerequisites
- `docs/router/specs.md` (canonical specification - READ FIRST, sections 2-13)
- `docs/router/02-Step.md` (detailed task breakdown for this sprint)
> **BLOCKED Tasks:** Before working on BLOCKED tasks, review [../implplan/BLOCKED_DEPENDENCY_TREE.md](../implplan/BLOCKED_DEPENDENCY_TREE.md) for root blockers and dependencies.

### IGlobalRoutingState
```csharp
public interface IGlobalRoutingState
{
EndpointDescriptor? ResolveEndpoint(string method, string path);
IReadOnlyList<ConnectionState> GetConnectionsFor(
string serviceName, string version, string method, string path);
}
```
### IRoutingPlugin
```csharp
public interface IRoutingPlugin
{
Task<RoutingDecision?> ChooseInstanceAsync(
RoutingContext context, CancellationToken cancellationToken);
}
```
### ITransportServer
```csharp
public interface ITransportServer
{
Task StartAsync(CancellationToken cancellationToken);
Task StopAsync(CancellationToken cancellationToken);
}
```
### ITransportClient
```csharp
public interface ITransportClient
{
Task<Frame> SendRequestAsync(
ConnectionState connection, Frame requestFrame,
TimeSpan timeout, CancellationToken cancellationToken);
Task SendCancelAsync(
ConnectionState connection, Guid correlationId, string? reason = null);
Task SendStreamingAsync(
ConnectionState connection, Frame requestHeader, Stream requestBody,
Func<Stream, Task> readResponseBody, PayloadLimits limits,
CancellationToken cancellationToken);
}
```
## Design Constraints
1. **No behavior:** Only shapes - no LINQ-heavy methods, no routing algorithms, no network code
2. **No serialization:** No JSON/MessagePack references; Common only defines shapes
3. **Immutability preferred:** Use `init` properties for descriptors; `ConnectionState` health fields may be mutable
4. **BCL only:** No ASP.NET or third-party package dependencies
5. **Nullable enabled:** All code must compile with zero nullable warnings
## Exit Criteria
Before marking this sprint DONE:
1. [x] All types from `specs.md` Common section exist with matching names and properties
2. [x] Common compiles with zero warnings
3. [x] Common only references BCL (verify no package references in .csproj)
4. [x] No behavior/logic in any type (pure DTOs and interfaces)
5. [x] `StellaOps.Router.Common.Tests` runs and passes
6. [x] `docs/router/specs.md` is updated if any discrepancy found (or code matches spec)
## Execution Log
| Date (UTC) | Update | Owner |
|------------|--------|-------|
| 2024-12-04 | Sprint completed: all models and interfaces implemented per spec | Claude |
## Decisions & Risks
- `RoutingContext` uses a neutral model (not ASP.NET `HttpContext`) to keep Common free of web dependencies. Gateway will adapt from `HttpContext` to this neutral model.
- `ConnectionState.Endpoints` uses `(string Method, string Path)` tuple as key for dictionary lookups.
- Frame payloads are `byte[]` - serialization happens at the transport layer, not in Common.

# Sprint 7000-0002-0001 · Router Transport · InMemory Plugin
## Topic & Scope
Build a fake "in-memory" transport plugin for development and testing. This transport proves the HELLO/HEARTBEAT/REQUEST/RESPONSE/CANCEL semantics and routing logic **without** dealing with sockets and RabbitMQ yet.
**Goal:** Enable unit and integration testing of the router and SDK by providing an in-process transport where frames are passed via channels/queues in memory.
**Working directory:** `src/__Libraries/StellaOps.Router.Transport.InMemory/`
**Key principle:** This plugin will never ship to production; it's only for dev tests and CI. It must fully implement all transport abstractions so that switching to real transports later requires zero changes to Gateway or Microservice SDK code.
## Dependencies & Concurrency
- **Upstream:** SPRINT_7000_0001_0002 (Common models must be complete)
- **Downstream:** SDK and Gateway sprints depend on this for testing
- **Parallel work:** Can run in parallel with CMN-040/041/042/043 test tasks if Common models are done
- **Cross-module impact:** None. Creates new directory only.
## Documentation Prerequisites
- `docs/router/specs.md` (sections 5, 10 - Transport and Cancellation requirements)
- `docs/router/03-Step.md` (detailed task breakdown)
- `docs/router/implplan.md` (phase 3 guidance)
> **BLOCKED Tasks:** Before working on BLOCKED tasks, review [../implplan/BLOCKED_DEPENDENCY_TREE.md](../implplan/BLOCKED_DEPENDENCY_TREE.md) for root blockers and dependencies.

## Architecture
```
┌──────────────────────┐ InMemoryConnectionRegistry ┌──────────────────────┐
│ Gateway │ (ConcurrentDictionary<ConnectionId, │ Microservice │
│ (InMemoryTransport │◄──── InMemoryChannel>) ────►│ (InMemoryTransport │
│ Server) │ │ Client) │
└──────────────────────┘ └──────────────────────┘
│ │
│ Channel<Frame> ToMicroservice ─────────────────────────────────────►│
│◄─────────────────────────────────────────────── Channel<Frame> ToGateway
│ │
```
## InMemoryChannel Design
```csharp
internal sealed class InMemoryChannel
{
public string ConnectionId { get; }
public Channel<Frame> ToMicroservice { get; } // Gateway writes, SDK reads
public Channel<Frame> ToGateway { get; } // SDK writes, Gateway reads
public InstanceDescriptor? Instance { get; set; }
public CancellationTokenSource LifetimeToken { get; }
}
```
## Frame Flow Examples
### HELLO Flow
1. Microservice SDK calls `InMemoryTransportClient.ConnectAsync()`
2. Client creates `InMemoryChannel`, registers in `InMemoryConnectionRegistry`
3. Client sends HELLO frame via `ToGateway` channel
4. Server reads from `ToGateway`, processes HELLO, updates `ConnectionState`
### REQUEST/RESPONSE Flow
1. Gateway receives HTTP request
2. Gateway sends REQUEST frame via `ToMicroservice` channel
3. SDK reads from `ToMicroservice`, invokes handler
4. SDK sends RESPONSE frame via `ToGateway` channel
5. Gateway reads from `ToGateway`, returns HTTP response
### CANCEL Flow
1. HTTP client disconnects (or timeout)
2. Gateway sends CANCEL frame via `ToMicroservice` channel
3. SDK reads CANCEL, cancels handler's CancellationToken
4. SDK optionally sends partial RESPONSE or no response
## Exit Criteria
Before marking this sprint DONE:
1. [x] `InMemoryTransportServer` fully implements `ITransportServer`
2. [x] `InMemoryTransportClient` fully implements `ITransportClient`
3. [x] All frame types (HELLO, HEARTBEAT, REQUEST, RESPONSE, STREAM_DATA, CANCEL) are handled
4. [x] Thread-safe concurrent access to `InMemoryConnectionRegistry`
5. [x] All integration tests pass
6. [x] No external dependencies (only BCL + Router.Common + DI/Options/Logging abstractions)
## Execution Log
| Date (UTC) | Update | Owner |
|------------|--------|-------|
| 2024-12-04 | Sprint completed: all InMemory transport components implemented and tested | Claude |
## Decisions & Risks
- Uses `System.Threading.Channels` for async frame passing (unbounded by default, can add backpressure later)
- InMemory transport simulates latency only if explicitly configured (default: instant)
- Connection lifetime is tied to `CancellationTokenSource`; disposing triggers cleanup
- This transport is explicitly excluded from production deployments via conditional compilation or package separation

# Sprint 7000-0003-0001 · Microservice SDK · Core Infrastructure
## Topic & Scope
Implement the core infrastructure of the Microservice SDK: options, endpoint discovery, and router connection management. After this sprint, a microservice can connect to a router and send HELLO with its endpoint list.
**Goal:** "Connect and say HELLO" - microservice connects to router(s) and registers its identity and endpoints.
**Working directory:** `src/__Libraries/StellaOps.Microservice/`
**Parallel track:** This sprint can run in parallel with Gateway sprints (7000-0004-*) once the InMemory transport is complete.
## Dependencies & Concurrency
- **Upstream:** SPRINT_7000_0001_0002 (Common), SPRINT_7000_0002_0001 (InMemory transport)
- **Downstream:** SPRINT_7000_0003_0002 (request handling)
- **Parallel work:** Can run in parallel with Gateway core sprint
- **Cross-module impact:** None. All work in `src/__Libraries/StellaOps.Microservice/`
## Documentation Prerequisites
- `docs/router/specs.md` (section 7 - Microservice SDK requirements)

| 18 | SDK-041 | DONE | Write integration tests with InMemory transport | Connect, HELLO, HEARTBEAT |
## Endpoint Discovery
### Attribute-Based Declaration
```csharp
[StellaEndpoint("POST", "/billing/invoices")]
public sealed class CreateInvoiceEndpoint : IStellaEndpoint<CreateInvoiceRequest, CreateInvoiceResponse>
{
public Task<CreateInvoiceResponse> HandleAsync(CreateInvoiceRequest request, CancellationToken ct);
}
```
### Discovery Flow
1. On startup, scan loaded assemblies for types with `[StellaEndpoint]`
2. For each type, verify it implements a handler interface
3. Build `EndpointDescriptor` from attribute + defaults
4. Store in `IEndpointRegistry` for lookup and HELLO construction
### Handler Interface Detection
```csharp
// Typed with request
typeof(IStellaEndpoint<TRequest, TResponse>)
// Typed without request
typeof(IStellaEndpoint<TResponse>)
// Raw handler
typeof(IRawStellaEndpoint)
```
## Connection Lifecycle
```
┌─────────────┐ Connect ┌─────────────┐ HELLO ┌─────────────┐
│ Disconnected│────────────────►│ Connected │───────────────►│ Registered │
└─────────────┘ └─────────────┘ └─────────────┘
▲ │ │
│ │ Error │ Heartbeat timer
│ ▼ ▼
│ ┌─────────────┐ ┌─────────────┐
└────────────────────────│ Reconnect │◄───────────────│ Heartbeat │
Backoff │ (backoff) │ Error │ Active │
└─────────────┘ └─────────────┘
```
## StellaMicroserviceOptions
```csharp
public sealed class StellaMicroserviceOptions
{
public string ServiceName { get; set; } = string.Empty;
public string Version { get; set; } = string.Empty; // Strict semver
public string Region { get; set; } = string.Empty;
public string InstanceId { get; set; } = string.Empty; // Auto-generate if empty
public IList<RouterEndpointConfig> Routers { get; set; } = new List<RouterEndpointConfig>();
public string? ConfigFilePath { get; set; } // Optional YAML overrides
public TimeSpan HeartbeatInterval { get; set; } = TimeSpan.FromSeconds(10);

2. [x] Endpoint discovery works via reflection
3. [x] Connection manager connects to configured routers
4. [x] HELLO frame sent on connection with full endpoint list
5. [x] HEARTBEAT sent periodically on timer
6. [x] Reconnection with backoff on connection failure
7. [x] Integration tests pass with InMemory transport
8. [x] `AddStellaMicroservice()` registers all services correctly
## Execution Log
| Date (UTC) | Update | Owner |
|------------|--------|-------|
| 2024-12-04 | Sprint completed: SDK core infrastructure implemented | Claude |
## Decisions & Risks
- Endpoint discovery defaults to reflection; source generation comes in a later sprint
- InstanceId auto-generates using `Guid.NewGuid().ToString("N")` if not provided
- Version validation enforces strict semver format
- Routers list cannot be empty - throws `InvalidOperationException` on startup
- YAML config file is optional at this stage (Sprint 7000-0007-0002)

## Handler Interfaces
### Raw Handler
```csharp
public interface IRawStellaEndpoint
{
Task<RawResponse> HandleAsync(RawRequestContext context, CancellationToken cancellationToken);
}
```
### Typed Handlers
```csharp
public interface IStellaEndpoint<TRequest, TResponse>
{
Task<TResponse> HandleAsync(TRequest request, CancellationToken cancellationToken);
}
public interface IStellaEndpoint<TResponse>
{
Task<TResponse> HandleAsync(CancellationToken cancellationToken);
}
```
## RawRequestContext
```csharp
public sealed class RawRequestContext
{
public string Method { get; init; } = string.Empty;
public string Path { get; init; } = string.Empty;
public IReadOnlyDictionary<string, string> PathParameters { get; init; }
= new Dictionary<string, string>();
public IHeaderCollection Headers { get; init; } = default!;
public Stream Body { get; init; } = Stream.Null;
public CancellationToken CancellationToken { get; init; }
}
```
## RawResponse
```csharp
public sealed class RawResponse
{
public int StatusCode { get; init; } = 200;
public IHeaderCollection Headers { get; init; } = default!;
public Stream Body { get; init; } = Stream.Null;
public static RawResponse Ok(Stream body) => new() { StatusCode = 200, Body = body };
public static RawResponse NotFound() => new() { StatusCode = 404 };
public static RawResponse Error(int statusCode, string message) => ...;
}
```
## Path Template Matching
Must use same rules as router (ASP.NET-style):
- `{id}` matches any segment, value captured in PathParameters
- `{id:int}` constraint support (optional for v1)
- Case sensitivity: configurable, default case-insensitive
- Trailing slash: configurable, default treats `/foo` and `/foo/` as equivalent
## Request Flow
```
┌─────────────────┐ ┌────────────────────┐ ┌───────────────────┐
│ REQUEST Frame │────►│ RequestDispatcher │────►│ IEndpointRegistry │
│ (from Router) │ │ │ │ (Method, Path) │

```
## Exit Criteria
Before marking this sprint DONE:
1. [ ] All handler interfaces defined and documented
2. [ ] `RawRequestContext` and `RawResponse` implemented
3. [ ] Path template matching works for common patterns
4. [ ] Typed handlers wrapped correctly via `TypedEndpointAdapter`
5. [ ] `RequestDispatcher` processes REQUEST frames end-to-end
6. [ ] DI integration works (handlers resolved from service provider)
7. [ ] Integration tests pass with InMemory transport
8. [ ] Body treated as opaque bytes (no interpretation at SDK level for raw handlers)
## Execution Log
| Date (UTC) | Update | Owner |
|------------|--------|-------|
| | | |
## Decisions & Risks
- Typed handlers use JSON serialization by default; configurable via options
- Path matching is case-insensitive by default (matches ASP.NET Core default)
- Each request gets its own DI scope for handler resolution
- Body stream may be buffered or streaming depending on endpoint configuration (streaming support comes in later sprint)
- Handler exceptions are caught and converted to 500 responses with error details (configurable)

# Sprint 7000-0004-0001 · Gateway · Core Infrastructure
## Topic & Scope
Implement the core infrastructure of the Gateway: node configuration, global routing state, and basic routing plugin. This sprint creates the foundation for HTTP → transport → microservice routing.
**Goal:** Gateway can maintain routing state from connected microservices and select instances for routing decisions.
**Working directory:** `src/Gateway/StellaOps.Gateway.WebService/`
**Parallel track:** This sprint can run in parallel with Microservice SDK sprints (7000-0003-*) once the InMemory transport is complete.
## Dependencies & Concurrency

- **Downstream:** SPRINT_7000_0004_0002 (middleware), SPRINT_7000_0004_0003 (connection handling)
- **Parallel work:** Can run in parallel with SDK core sprint
- **Cross-module impact:** None. All work in `src/Gateway/StellaOps.Gateway.WebService/`
## Documentation Prerequisites
- `docs/router/specs.md` (section 6 - Gateway requirements)
- `docs/router/05-Step.md` (detailed task breakdown)
- `docs/router/implplan.md` (phase 5 guidance)

| 14 | GW-030 | TODO | Create `RoutingOptions` for configurable behavior | Default version, neighbor regions |
| 15 | GW-031 | TODO | Register routing services in DI | IGlobalRoutingState, IRoutingPlugin |
| 16 | GW-040 | TODO | Write unit tests for InMemoryRoutingState | |
| 17 | GW-041 | TODO | Write unit tests for DefaultRoutingPlugin | Version, health, region filtering |
## GatewayNodeConfig
```csharp
public sealed class GatewayNodeConfig
{
public string Region { get; set; } = string.Empty; // Required, e.g. "eu1"
public string NodeId { get; set; } = string.Empty; // e.g. "gw-eu1-01"
public string Environment { get; set; } = string.Empty; // e.g. "prod"
public IList<string> NeighborRegions { get; set; } = []; // Fallback regions
}
```
**Configuration binding:**
```json
{
"GatewayNode": {
"Region": "eu1",
"NodeId": "gw-eu1-01",
"Environment": "prod",
"NeighborRegions": ["eu2", "us1"]
}
}
```
## InMemoryRoutingState
```csharp
internal sealed class InMemoryRoutingState : IGlobalRoutingState
{
private readonly ConcurrentDictionary<string, ConnectionState> _connections = new();
private readonly ConcurrentDictionary<(string Method, string Path), List<string>> _endpointIndex = new();
public void AddConnection(ConnectionState connection) { ... }
public void RemoveConnection(string connectionId) { ... }
public void UpdateConnection(string connectionId, Action<ConnectionState> update) { ... }
public EndpointDescriptor? ResolveEndpoint(string method, string path) { ... }
public IReadOnlyList<ConnectionState> GetConnectionsFor(
string serviceName, string version, string method, string path) { ... }
}
```
## Routing Algorithm (Phase 1 - Basic)
```
1. Filter by ServiceName (exact match)
2. Filter by Version (strict semver equality)
3. Filter by Health (Healthy or Degraded only)
4. If any remain, pick one (random for now)
5. If none, return null (503 Service Unavailable)
```
**Note:** Full routing algorithm (region preference, ping-based selection, fallback) is implemented in SPRINT_7000_0005_0002.
## Region Derivation
Per spec section 2:
> Routing decisions MUST use `GatewayNodeConfig.Region` as the node's region; the router MUST NOT derive region from HTTP headers or URL host names.
This is enforced by:
1. GatewayNodeConfig is bound from static configuration only
2. No code path reads region from HttpContext
3. Tests verify region is never extracted from Host header
## Exit Criteria
Before marking this sprint DONE:
1. [ ] `GatewayNodeConfig` loads and validates from configuration
2. [ ] `InMemoryRoutingState` stores and indexes connections correctly
3. [ ] `ResolveEndpoint` performs path template matching
4. [ ] `DefaultRoutingPlugin` filters by version, health, region
5. [ ] All services registered in DI container
6. [ ] Unit tests pass for routing state and plugin

- Routing state is in-memory only; no persistence or distribution (single gateway node for v1)
- Path template matching reuses logic from SDK (shared in Common or duplicated)
- DefaultRoutingPlugin is intentionally simple; full algorithm comes in SPRINT_7000_0005_0002
- Region validation: startup fails fast if Region is empty

# Sprint 7000-0004-0002 · Gateway · HTTP Middleware Pipeline
## Topic & Scope
Implement the HTTP middleware pipeline for the Gateway: endpoint resolution, authorization, routing decision, and transport dispatch. After this sprint, HTTP requests flow through the gateway to microservices via the InMemory transport.
**Goal:** Complete HTTP → transport → microservice → HTTP flow for basic buffered requests.
**Working directory:** `src/Gateway/StellaOps.Gateway.WebService/`
## Dependencies & Concurrency
- **Upstream:** SPRINT_7000_0004_0001 (Gateway core)
- **Downstream:** SPRINT_7000_0004_0003 (connection handling)
- **Parallel work:** Can run in parallel with SDK request handling sprint
- **Cross-module impact:** None. All work in `src/Gateway/StellaOps.Gateway.WebService/`
## Documentation Prerequisites
- `docs/router/specs.md` (section 6.1 - HTTP ingress pipeline)
- `docs/router/05-Step.md` (middleware section)
> **BLOCKED Tasks:** Before working on BLOCKED tasks, review [../implplan/BLOCKED_DEPENDENCY_TREE.md](../implplan/BLOCKED_DEPENDENCY_TREE.md) for root blockers and dependencies.

## Middleware Pipeline Order
```csharp
app.UseForwardedHeaders(); // Reverse proxy support
app.UseMiddleware<GlobalErrorHandlerMiddleware>();
app.UseMiddleware<RequestLoggingMiddleware>();

{
var method = context.Request.Method;
var path = context.Request.Path.Value ?? "/";
var endpoint = routingState.ResolveEndpoint(method, path);

```csharp
public class TransportDispatchMiddleware
{
public async Task InvokeAsync(HttpContext context, ITransportClient transport)
{
var decision = (RoutingDecision)context.Items["RoutingDecision"]!;
var endpoint = (EndpointDescriptor)context.Items["ResolvedEndpoint"]!;
// Build REQUEST frame
using var bodyStream = new MemoryStream();
await context.Request.Body.CopyToAsync(bodyStream);
var requestFrame = new Frame
{
Type = FrameType.Request,
CorrelationId = Guid.NewGuid(),
Payload = BuildRequestPayload(context, bodyStream.ToArray())
};
// Send and await response
using var cts = CancellationTokenSource.CreateLinkedTokenSource(
context.RequestAborted);
cts.CancelAfter(decision.EffectiveTimeout);
var responseFrame = await transport.SendRequestAsync(
decision.Connection,
requestFrame,
decision.EffectiveTimeout,
cts.Token);
// Write response to HTTP
await WriteHttpResponse(context, responseFrame);
}
}
```
## Error Mapping
| Transport/Routing Error | HTTP Status |
|------------------------|-------------|
| Endpoint not found | 404 Not Found |
| No healthy instance | 503 Service Unavailable |
| Timeout | 504 Gateway Timeout |
| Microservice error (5xx) | Pass through status |
| Transport connection lost | 502 Bad Gateway |
| Payload too large | 413 Payload Too Large |
| Unauthorized | 401 Unauthorized |
| Forbidden (claims) | 403 Forbidden |
## HttpContext.Items Keys
```csharp
public static class ContextKeys
{
public const string ResolvedEndpoint = "ResolvedEndpoint";
public const string RoutingDecision = "RoutingDecision";
public const string CorrelationId = "CorrelationId";
}
```
## Exit Criteria
Before marking this sprint DONE:
1. [ ] All middleware classes implemented
2. [ ] Pipeline configured in correct order
3. [ ] EndpointResolutionMiddleware resolves (Method, Path) → endpoint
4. [ ] AuthorizationMiddleware checks authentication (claims in later sprint)
5. [ ] RoutingDecisionMiddleware selects instance via IRoutingPlugin
6. [ ] TransportDispatchMiddleware sends/receives frames (buffered mode)
7. [ ] Error responses use consistent JSON envelope
8. [ ] Integration tests pass with InMemory transport
## Execution Log
| Date (UTC) | Update | Owner |
|------------|--------|-------|
| | | |
## Decisions & Risks
- Authorization middleware is a stub that only checks `User.Identity?.IsAuthenticated`; full RequiringClaims enforcement comes in SPRINT_7000_0008_0001
- Streaming support is not implemented in this sprint; TransportDispatchMiddleware only handles buffered mode
- Correlation ID is generated per request and logged throughout
- Request body is fully read into memory for buffered mode; streaming in SPRINT_7000_0005_0004

# Sprint 7000-0004-0003 · Gateway · Connection Handling
## Topic & Scope
Implement connection handling in the Gateway: processing HELLO frames from microservices, maintaining connection state, and updating the global routing state. After this sprint, microservices can register with the gateway and be routed to.
**Goal:** Gateway receives HELLO from microservices and maintains live routing state. Combined with previous sprints, this enables full end-to-end HTTP → microservice routing.
**Working directory:** `src/Gateway/StellaOps.Gateway.WebService/`
## Dependencies & Concurrency
- **Upstream:** SPRINT_7000_0004_0002 (middleware), SPRINT_7000_0003_0001 (SDK core with HELLO)
- **Downstream:** SPRINT_7000_0005_0001 (heartbeat/health)
- **Parallel work:** Should coordinate with SDK team for HELLO frame format agreement
- **Cross-module impact:** None. All work in Gateway.
## Documentation Prerequisites
- `docs/router/specs.md` (section 6.2 - Per-connection state and routing view)
- `docs/router/05-Step.md` (connection handling section)
> **BLOCKED Tasks:** Before working on BLOCKED tasks, review [../implplan/BLOCKED_DEPENDENCY_TREE.md](../implplan/BLOCKED_DEPENDENCY_TREE.md) for root blockers and dependencies.

## HELLO Processing
```csharp
internal sealed class ConnectionHandler : IConnectionHandler
{
public async Task HandleFrameAsync(string connectionId, Frame frame)
{
switch (frame.Type)
{
case FrameType.Hello:
await ProcessHelloAsync(connectionId, frame);
break;
case FrameType.Heartbeat:
await ProcessHeartbeatAsync(connectionId, frame);
break;
case FrameType.Response:
case FrameType.ResponseStreamData:
await ProcessResponseAsync(connectionId, frame);
break;
default:
_logger.LogWarning("Unknown frame type {Type} from {ConnectionId}",
frame.Type, connectionId);
break;
}
}
private async Task ProcessHelloAsync(string connectionId, Frame frame)
{
var payload = DeserializeHelloPayload(frame.Payload);
// Validate
if (string.IsNullOrEmpty(payload.Instance.ServiceName))
throw new InvalidHelloException("ServiceName required");
if (string.IsNullOrEmpty(payload.Instance.Version))
throw new InvalidHelloException("Version required");
// Build ConnectionState
var connection = new ConnectionState
{
ConnectionId = connectionId,
Instance = payload.Instance,
Status = InstanceHealthStatus.Unknown,
LastHeartbeatUtc = DateTime.UtcNow,
TransportType = _currentTransportType,
Endpoints = payload.Endpoints.ToDictionary(
e => (e.Method, e.Path),
e => e)
};
// Register
_routingState.AddConnection(connection);
_logger.LogInformation(
"Registered {ServiceName} v{Version} instance {InstanceId} from {Region}",
payload.Instance.ServiceName,
payload.Instance.Version,
payload.Instance.InstanceId,
payload.Instance.Region);
}
}
```
## TransportServerHost
```csharp
internal sealed class TransportServerHost : IHostedService
{
private readonly ITransportServer _server;
private readonly IConnectionHandler _handler;
public async Task StartAsync(CancellationToken cancellationToken)
{
_server.OnConnection += HandleNewConnection;
_server.OnFrame += HandleFrame;
_server.OnDisconnect += HandleDisconnect;
await _server.StartAsync(cancellationToken);
}
private void HandleNewConnection(string connectionId)
{
_logger.LogInformation("New connection: {ConnectionId}", connectionId);
}
private async Task HandleFrame(string connectionId, Frame frame)
{
await _handler.HandleFrameAsync(connectionId, frame);
}
private void HandleDisconnect(string connectionId)
{
_routingState.RemoveConnection(connectionId);
_logger.LogInformation("Connection closed: {ConnectionId}", connectionId);
}
}
```
## Multiple Instances
The gateway must handle multiple instances of the same service:
- Same ServiceName + Version from different InstanceIds
- Each instance has its own ConnectionState
- Routing algorithm selects among available instances
```
Service: billing v1.0.0
├── Instance: billing-01 (Region: eu1) → Connection abc123
├── Instance: billing-02 (Region: eu1) → Connection def456
└── Instance: billing-03 (Region: us1) → Connection ghi789
```
## Exit Criteria
Before marking this sprint DONE:
1. [ ] HELLO frames processed correctly
2. [ ] ConnectionState created and stored
3. [ ] Endpoint index updated for routing lookups
4. [ ] Connection cleanup removes all state
5. [ ] TransportServerHost starts/stops with application
6. [ ] Integration tests: SDK registers, Gateway routes, SDK handles request
## Execution Log
| Date (UTC) | Update | Owner |
|------------|--------|-------|
| | | |
## Decisions & Risks
- Initial health status is `Unknown` until first heartbeat
- Connection ID format: GUID for InMemory, transport-specific for real transports
- HELLO validation failure disconnects the client (logs error)
- Duplicate HELLO from same connection replaces existing state (re-registration)

# Sprint 7000-0005-0001 · Protocol Features · Heartbeat & Health
## Topic & Scope
Implement heartbeat processing and health tracking. Microservices send HEARTBEAT frames periodically; the gateway updates health status and marks stale instances as unhealthy.
**Goal:** Gateway maintains accurate health status for all connected instances, enabling health-aware routing.
**Working directories:**
- `src/__Libraries/StellaOps.Microservice/` (heartbeat sending)
- `src/Gateway/StellaOps.Gateway.WebService/` (heartbeat processing)
- `src/__Libraries/StellaOps.Router.Common/` (if payload changes needed)
## Dependencies & Concurrency
- **Upstream:** SPRINT_7000_0004_0003 (Gateway connection handling), SPRINT_7000_0003_0001 (SDK core)
- **Downstream:** SPRINT_7000_0005_0002 (routing algorithm uses health)
- **Parallel work:** None. Sequential after connection handling.
- **Cross-module impact:** SDK and Gateway both modified.
## Documentation Prerequisites
- `docs/router/specs.md` (section 8 - Control/health/ping requirements)
- `docs/router/06-Step.md` (heartbeat section)
- `docs/router/implplan.md` (phase 6 guidance)
> **BLOCKED Tasks:** Before working on BLOCKED tasks, review [../implplan/BLOCKED_DEPENDENCY_TREE.md](../implplan/BLOCKED_DEPENDENCY_TREE.md) for root blockers and dependencies.
## Delivery Tracker
| # | Task ID | Status | Description | Working Directory |

| 19 | HB-051 | DONE | Update AveragePingMs from timing | Exponential moving average |
| 20 | HB-060 | DONE | Write integration tests for heartbeat flow | |
| 21 | HB-061 | DONE | Write tests for health status transitions | |
| 22 | HB-062 | DONE | Write tests for stale detection | |
## HeartbeatPayload
```csharp
public sealed class HeartbeatPayload
{
public string InstanceId { get; init; } = string.Empty;
public InstanceHealthStatus Status { get; init; }
public int? InflightRequestCount { get; init; }
public double? ErrorRatePercent { get; init; }
public DateTimeOffset Timestamp { get; init; }
}
```
## Health Status Transitions
```
┌─────────┐
First │ Unknown │
Heartbeat └────┬────┘
│ Status from payload
▼
┌─────────┐
◄────────────────│ Healthy │◄───────────────┐
│ Degraded └────┬────┘ Healthy │
│ in payload │ │
▼ │ Stale threshold │
┌──────────┐ │ exceeded │
│ Degraded │ ▼ │
└────┬─────┘ ┌───────────┐ │
│ │ Unhealthy │───────────────┘
│ Stale └───────────┘ Heartbeat
│ threshold received
▼
┌───────────┐
│ Unhealthy │
└───────────┘
```
**Special case: Draining**
- Microservice explicitly sets status to `Draining`
- Router stops sending new requests but allows in-flight to complete
- Used for graceful shutdown
## HealthMonitorService
```csharp
internal sealed class HealthMonitorService : BackgroundService
{
private readonly IGlobalRoutingState _routingState;
private readonly IOptions<HealthOptions> _options;
protected override async Task ExecuteAsync(CancellationToken stoppingToken)
{
var interval = TimeSpan.FromSeconds(5); // Check frequency
while (!stoppingToken.IsCancellationRequested)
{
CheckStaleConnections();
await Task.Delay(interval, stoppingToken);
}
}
private void CheckStaleConnections()
{
var threshold = _options.Value.StaleThreshold;
var now = DateTime.UtcNow;
foreach (var connection in _routingState.GetAllConnections())
{
var age = now - connection.LastHeartbeatUtc;
if (age > threshold && connection.Status != InstanceHealthStatus.Unhealthy)
{
_routingState.UpdateConnection(connection.ConnectionId,
c => c.Status = InstanceHealthStatus.Unhealthy);
_logger.LogWarning(
"Instance {InstanceId} marked Unhealthy: no heartbeat for {Age}",
connection.Instance.InstanceId, age);
}
}
}
}
```
## HealthOptions
```csharp
public sealed class HealthOptions
{
public TimeSpan StaleThreshold { get; set; } = TimeSpan.FromSeconds(30);
public TimeSpan DegradedThreshold { get; set; } = TimeSpan.FromSeconds(15);
public int PingHistorySize { get; set; } = 10; // For moving average
}
```
## Ping Latency Measurement
Measure round-trip time for REQUEST/RESPONSE:
1. Record timestamp when REQUEST frame sent
2. Record timestamp when RESPONSE frame received
3. Calculate RTT = response_time - request_time
4. Update exponential moving average: `avg = 0.8 * avg + 0.2 * rtt`
```csharp
internal sealed class PingTracker
{
private readonly ConcurrentDictionary<Guid, long> _pendingRequests = new();
private double _averagePingMs;
public void RecordRequestSent(Guid correlationId)
{
_pendingRequests[correlationId] = Stopwatch.GetTimestamp();
}
public void RecordResponseReceived(Guid correlationId)
{
if (_pendingRequests.TryRemove(correlationId, out var startTicks))
{
var elapsed = Stopwatch.GetElapsedTime(startTicks);
var rtt = elapsed.TotalMilliseconds;
_averagePingMs = 0.8 * _averagePingMs + 0.2 * rtt;
}
}
public double AveragePingMs => _averagePingMs;
}
```
## Exit Criteria
Before marking this sprint DONE:
1. [x] SDK sends HEARTBEAT frames on timer
2. [x] Gateway processes HEARTBEAT and updates ConnectionState
3. [x] HealthMonitorService marks stale instances Unhealthy
4. [x] Draining status stops new requests
5. [x] Ping latency measured and stored
6. [x] Health thresholds configurable
7. [x] Integration tests pass
## Execution Log
| Date (UTC) | Update | Owner |
|------------|--------|-------|
| 2025-12-05 | Sprint completed. Implemented heartbeat sending in SDK, health monitoring in Gateway, ping latency tracking. 51 tests passing. | Claude |
## Decisions & Risks
- Heartbeat interval default: 10 seconds (configurable)
- Stale threshold default: 30 seconds (3 missed heartbeats)
- Ping measurement uses REQUEST/RESPONSE timing, not separate PING frames
- Health status changes are logged for observability

## Routing Algorithm
```
Input: (ServiceName, Version, Method, Path)
Output: ConnectionState or null
1. Get all connections from IGlobalRoutingState.GetConnectionsFor(...)
2. Filter by ServiceName
- connections.Where(c => c.Instance.ServiceName == serviceName)
3. Filter by Version (strict semver equality)
- connections.Where(c => c.Instance.Version == version)
- If version not specified, use DefaultVersion from config
4. Filter by Health
- connections.Where(c => c.Status in {Healthy, Degraded})
- Exclude Unknown, Draining, Unhealthy
5. Group by Region Tier
- Tier 0: c.Instance.Region == GatewayNodeConfig.Region
- Tier 1: c.Instance.Region in GatewayNodeConfig.NeighborRegions
- Tier 2: All others
6. For each tier (0, 1, 2), if any candidates exist:
a. Sort by AveragePingMs (ascending)
b. For ties, sort by LastHeartbeatUtc (descending = more recent first)
c. For remaining ties, apply tie-breaker (random or round-robin)
d. Return first candidate
7. If no candidates in any tier, return null (503)
```
## Implementation
```csharp
public class DefaultRoutingPlugin : IRoutingPlugin
{
public async Task<RoutingDecision?> ChooseInstanceAsync(
RoutingContext context, CancellationToken cancellationToken)
{
var endpoint = context.Endpoint;
var gatewayRegion = context.GatewayRegion;
// Get all matching connections
var connections = _routingState.GetConnectionsFor(
endpoint.ServiceName,
endpoint.Version,
endpoint.Method,
endpoint.Path);
// Filter by health
var healthy = connections
.Where(c => c.Status is InstanceHealthStatus.Healthy
or InstanceHealthStatus.Degraded)
.ToList();
if (healthy.Count == 0)
return null;
// Group by region tier
var tier0 = healthy.Where(c => c.Instance.Region == gatewayRegion).ToList();
var tier1 = healthy.Where(c =>
_options.NeighborRegions.Contains(c.Instance.Region)).ToList();
var tier2 = healthy.Except(tier0).Except(tier1).ToList();
// Select from best tier
var selected = SelectFromTier(tier0)
?? SelectFromTier(tier1)
?? SelectFromTier(tier2);
if (selected == null)
return null;
return new RoutingDecision
{
Endpoint = endpoint,
Connection = selected,
TransportType = selected.TransportType,
EffectiveTimeout = endpoint.DefaultTimeout

private ConnectionState? SelectFromTier(List<ConnectionState> tier)
{
if (tier.Count == 0)
return null;
// Sort by ping (asc), then heartbeat (desc)
var sorted = tier
.OrderBy(c => c.AveragePingMs)
.ThenByDescending(c => c.LastHeartbeatUtc)
.ToList();
// Tie-breaker for same ping and heartbeat
var best = sorted.First();
var tied = sorted.TakeWhile(c =>
Math.Abs(c.AveragePingMs - best.AveragePingMs) < 0.1
&& c.LastHeartbeatUtc == best.LastHeartbeatUtc).ToList();
if (tied.Count == 1)
return tied[0];
// Round-robin or random for ties
return _options.TieBreaker == TieBreakerMode.Random
? tied[Random.Shared.Next(tied.Count)]
: tied[_roundRobinCounter++ % tied.Count];
}
}
```
## RoutingOptions
```csharp
public sealed class RoutingOptions
{
public Dictionary<string, string> DefaultVersions { get; set; } = new();
public HashSet<InstanceHealthStatus> AcceptableStatuses { get; set; }
= new() { InstanceHealthStatus.Healthy, InstanceHealthStatus.Degraded };
public TieBreakerMode TieBreaker { get; set; } = TieBreakerMode.RoundRobin;
}
public enum TieBreakerMode
{
Random,
RoundRobin
}
```
## Spec Compliance Verification
From specs.md section 4:
> * Region:
> * Prefer instances whose `Region == GatewayNodeConfig.Region`.
> * If none, fall back to configured neighbor regions.
> * If none, fall back to all other regions.
> * Within a chosen region tier:
> * Prefer lower `AveragePingMs`.
> * If several are tied, prefer more recent `LastHeartbeatUtc`.
> * If still tied, use a balancing strategy (e.g. random or round-robin).
Implementation must match exactly.
## Exit Criteria
Before marking this sprint DONE:
1. [x] Full filter chain implemented (service, version, health)
2. [x] Region tier logic works (same region → neighbors → others)
3. [x] Scoring within tier (ping, heartbeat, tie-breaker)
4. [x] RoutingOptions configurable
5. [x] All unit tests pass
6. [x] Integration tests verify routing decisions
## Execution Log
| Date (UTC) | Update | Owner |
|------------|--------|-------|
| 2025-12-05 | Sprint completed. Full routing algorithm with region tiers, ping/heartbeat scoring, and tie-breaking. 55 tests passing. | Claude |
## Decisions & Risks
- Ping tolerance for "ties": 0.1ms difference considered equal
- Round-robin counter is per-endpoint to avoid hot instances
- DefaultVersion lookup is per-service from configuration
- Degraded instances are routed to (may want to prefer Healthy first)

# Sprint 7000-0005-0003 · Protocol Features · Cancellation Semantics
## Topic & Scope
Implement cancellation semantics on both gateway and microservice sides. When HTTP clients disconnect, timeouts occur, or payload limits are breached, CANCEL frames are sent to stop in-flight work.
**Goal:** Clean cancellation propagation from HTTP client through gateway to microservice handlers.
**Working directories:**
- `src/Gateway/StellaOps.Gateway.WebService/` (send CANCEL)
- `src/__Libraries/StellaOps.Microservice/` (receive CANCEL, cancel handler)
- `src/__Libraries/StellaOps.Router.Common/` (CancelPayload)
## Dependencies & Concurrency
- **Upstream:** SPRINT_7000_0005_0002 (routing algorithm complete)
- **Downstream:** SPRINT_7000_0005_0004 (streaming uses cancellation)
- **Parallel work:** None. Sequential.
- **Cross-module impact:** SDK and Gateway both modified.
## Documentation Prerequisites
- `docs/router/specs.md` (sections 7.6, 10 - Cancellation requirements)
- `docs/router/07-Step.md` (cancellation section)
- `docs/router/implplan.md` (phase 7 guidance)
> **BLOCKED Tasks:** Before working on BLOCKED tasks, review [../implplan/BLOCKED_DEPENDENCY_TREE.md](../implplan/BLOCKED_DEPENDENCY_TREE.md) for root blockers and dependencies.

## CancelPayload
```csharp
public sealed class CancelPayload
{
public string Reason { get; init; } = string.Empty;
}
public static class CancelReasons
{
public const string ClientDisconnected = "ClientDisconnected";
public const string Timeout = "Timeout";
public const string PayloadLimitExceeded = "PayloadLimitExceeded";
public const string Shutdown = "Shutdown";
}
```
## Gateway-Side: Sending CANCEL
### On Client Disconnect
```csharp
// In TransportDispatchMiddleware
context.RequestAborted.Register(async () =>
{
await transport.SendCancelAsync(
connection,
correlationId,
CancelReasons.ClientDisconnected);
});
```
### On Timeout
```csharp
using var cts = CancellationTokenSource.CreateLinkedTokenSource(context.RequestAborted);
cts.CancelAfter(decision.EffectiveTimeout);
try
{
var response = await transport.SendRequestAsync(..., cts.Token);
}
catch (OperationCanceledException) when (cts.IsCancellationRequested)
{
if (!context.RequestAborted.IsCancellationRequested)
{
// Timeout, not client disconnect
await transport.SendCancelAsync(connection, correlationId, CancelReasons.Timeout);
context.Response.StatusCode = 504;
return;
}
}
```
### Late Response Handling
```csharp
private readonly ConcurrentDictionary<Guid, bool> _cancelledRequests = new();
public void MarkCancelled(Guid correlationId)
{
_cancelledRequests[correlationId] = true;
}
public bool IsCancelled(Guid correlationId)
{
return _cancelledRequests.ContainsKey(correlationId);
}
// When response arrives
if (IsCancelled(frame.CorrelationId))
{
_logger.LogDebug("Ignoring late response for cancelled {CorrelationId}", frame.CorrelationId);
return; // Discard
}
```
## Microservice-Side: Receiving CANCEL
### Inflight Tracking
```csharp
internal sealed class InflightRequestTracker
{
private readonly ConcurrentDictionary<Guid, InflightRequest> _inflight = new();
public CancellationToken Track(Guid correlationId, Task handlerTask)
{
var cts = new CancellationTokenSource();
_inflight[correlationId] = new InflightRequest(cts, handlerTask);
return cts.Token;
}
public void Cancel(Guid correlationId, string reason)
{
if (_inflight.TryGetValue(correlationId, out var request))
{
request.Cts.Cancel();
_logger.LogInformation("Cancelled {CorrelationId}: {Reason}", correlationId, reason);
}
}
public void Complete(Guid correlationId)
{
if (_inflight.TryRemove(correlationId, out var request))
{
request.Cts.Dispose();
}
}
public void CancelAll(string reason)
{
foreach (var kvp in _inflight)
{
kvp.Value.Cts.Cancel();
}
_inflight.Clear();
}
}
```
### Connection-Close Handling
```csharp
// When connection closes unexpectedly
_inflightTracker.CancelAll("ConnectionClosed");
```
## Handler Cancellation Guidelines
Handlers MUST:
1. Accept `CancellationToken` parameter
2. Pass token to all async I/O operations
3. Check `token.IsCancellationRequested` in loops
4. Stop work promptly when cancelled
```csharp
public class ProcessDataEndpoint : IStellaEndpoint<DataRequest, DataResponse>
{
public async Task<DataResponse> HandleAsync(DataRequest request, CancellationToken ct)
{
// Pass token to I/O
var data = await _database.QueryAsync(request.Id, ct);
// Check in loops
foreach (var item in data)
{
ct.ThrowIfCancellationRequested();
await ProcessItemAsync(item, ct);
}
return new DataResponse { ... };
}
}
```
## Exit Criteria
Before marking this sprint DONE:
1. [x] CANCEL frames sent on client disconnect
2. [x] CANCEL frames sent on timeout
3. [x] SDK tracks inflight requests with CTS
4. [x] SDK cancels handlers on CANCEL frame
5. [x] Connection close cancels all inflight
6. [x] Late responses are ignored/logged
7. [x] Integration tests verify cancellation flow
## Execution Log
| Date (UTC) | Update | Owner |
|------------|--------|-------|
| 2025-12-05 | Sprint DONE - CancelReasons defined, InflightRequestTracker implemented, Gateway sends CANCEL on disconnect/timeout, SDK handles CANCEL frames, 67 tests pass | Claude |
## Decisions & Risks
- Cancellation is cooperative; handlers must honor the token
- CTS disposal happens on completion to avoid leaks
- Late response cleanup: entries expire after 60 seconds
- Shutdown CANCEL is best-effort (connections may close first)

## Streaming Frame Protocol
### Request Streaming
```
Gateway → Microservice:
1. REQUEST frame (headers, method, path, CorrelationId)
2. REQUEST_STREAM_DATA frame (chunk 1)
3. REQUEST_STREAM_DATA frame (chunk 2)
...
N. REQUEST_STREAM_DATA frame (final chunk, EndOfStream=true)
```
### Response Streaming
```
Microservice → Gateway:
1. RESPONSE frame (status code, headers, CorrelationId)
2. RESPONSE_STREAM_DATA frame (chunk 1)
3. RESPONSE_STREAM_DATA frame (chunk 2)
...
N. RESPONSE_STREAM_DATA frame (final chunk, EndOfStream=true)
```
## StreamDataPayload
```csharp
public sealed class StreamDataPayload
{
public Guid CorrelationId { get; init; }
public byte[] Data { get; init; } = Array.Empty<byte>();
public bool EndOfStream { get; init; }
public int SequenceNumber { get; init; }
}
```
## Gateway Streaming Dispatch
```csharp
// In TransportDispatchMiddleware
if (endpoint.SupportsStreaming)
{
await DispatchStreamingAsync(context, transport, decision, cancellationToken);
}
else
{
await DispatchBufferedAsync(context, transport, decision, cancellationToken);
}
private async Task DispatchStreamingAsync(...)
{
// Send REQUEST header
var requestFrame = BuildRequestHeaderFrame(context);
await transport.SendFrameAsync(connection, requestFrame, ct);
// Stream body chunks
var buffer = new byte[_options.StreamChunkSize];
int bytesRead;
int sequence = 0;
while ((bytesRead = await context.Request.Body.ReadAsync(buffer, ct)) > 0)
{
var streamFrame = new Frame
{
Type = FrameType.RequestStreamData,
CorrelationId = requestFrame.CorrelationId,
Payload = SerializeStreamData(buffer[..bytesRead], sequence++, endOfStream: false)
};
await transport.SendFrameAsync(connection, streamFrame, ct);
}
// Send end-of-stream
var endFrame = new Frame
{
Type = FrameType.RequestStreamData,
CorrelationId = requestFrame.CorrelationId,
Payload = SerializeStreamData(Array.Empty<byte>(), sequence, endOfStream: true)
};
await transport.SendFrameAsync(connection, endFrame, ct);
// Receive response (streaming or buffered)
await ReceiveResponseAsync(context, transport, connection, requestFrame.CorrelationId, ct);
}
```
## Microservice Streaming Handler
```csharp
[StellaEndpoint("POST", "/files/upload", SupportsStreaming = true)]
public class FileUploadEndpoint : IRawStellaEndpoint
{
public async Task<RawResponse> HandleAsync(RawRequestContext context, CancellationToken ct)
{
// Body is a stream that reads from REQUEST_STREAM_DATA frames
var tempPath = Path.GetTempFileName();
await using var fileStream = File.Create(tempPath);
await context.Body.CopyToAsync(fileStream, ct);
return RawResponse.Ok($"Uploaded {fileStream.Length} bytes");
}
}
[StellaEndpoint("GET", "/files/{id}/download", SupportsStreaming = true)]
public class FileDownloadEndpoint : IRawStellaEndpoint
{
public async Task<RawResponse> HandleAsync(RawRequestContext context, CancellationToken ct)
{
var fileId = context.PathParameters["id"];
var filePath = _storage.GetPath(fileId);
// Return streaming response
return new RawResponse
{
StatusCode = 200,
Body = File.OpenRead(filePath), // Stream, not buffered
Headers = new HeaderCollection
{
["Content-Type"] = "application/octet-stream"
}
};
}
}
```
## StreamingOptions
```csharp
public sealed class StreamingOptions
{
public int ChunkSize { get; set; } = 64 * 1024; // 64KB default
public int MaxConcurrentStreams { get; set; } = 100;
public TimeSpan StreamIdleTimeout { get; set; } = TimeSpan.FromMinutes(5);
}
```
## Exit Criteria
Before marking this sprint DONE:
1. [x] REQUEST_STREAM_DATA frames implemented in transport
2. [x] RESPONSE_STREAM_DATA frames implemented in transport
3. [x] Gateway streams request body to microservice
4. [x] Gateway streams response body to HTTP client
5. [x] SDK exposes streaming Body in RawRequestContext
6. [x] SDK can write streaming response
7. [x] Cancellation works during streaming
8. [x] Integration tests for upload and download streaming
## Execution Log
| Date (UTC) | Update | Owner |
|------------|--------|-------|
| 2025-12-05 | Sprint DONE - StreamDataPayload, StreamingOptions, StreamingRequestBodyStream, StreamingResponseBodyStream, DispatchStreamingAsync in gateway, 80 tests pass | Claude |
## Decisions & Risks
- Default chunk size: 64KB (tunable)
- End-of-stream is explicit frame, not connection close
- Backpressure via channel capacity (bounded channels)
- Idle timeout cancels stuck streams
- Typed handlers don't support streaming (use IRawStellaEndpoint)

# Sprint 7000-0005-0005 · Protocol Features · Payload Limits
## Topic & Scope
Implement payload size limits to protect the gateway from memory exhaustion. Enforce limits per-request, per-connection, and aggregate across all connections.

**Working directory:** `src/Gateway/StellaOps.Gateway.WebService/`
## Dependencies & Concurrency
- **Upstream:** SPRINT_7000_0005_0004 (streaming - limits apply to streams)

| 23 | LIM-072 | DONE | Write tests for connection limit | PayloadTrackerTests |
| 24 | LIM-073 | DONE | Write tests for aggregate limit | PayloadTrackerTests |
## PayloadLimits
```csharp
public sealed class PayloadLimits
{
public long MaxRequestBytesPerCall { get; set; } = 10 * 1024 * 1024; // 10 MB
public long MaxRequestBytesPerConnection { get; set; } = 100 * 1024 * 1024; // 100 MB
public long MaxAggregateInflightBytes { get; set; } = 1024 * 1024 * 1024; // 1 GB
}
```
## PayloadLimitsMiddleware
```csharp
public class PayloadLimitsMiddleware
{
public async Task InvokeAsync(HttpContext context, IPayloadTracker tracker)
{
// Early rejection for known Content-Length
if (context.Request.ContentLength.HasValue)
{
if (context.Request.ContentLength > _limits.MaxRequestBytesPerCall)
{
_logger.LogWarning("Request rejected: Content-Length {Length} exceeds limit {Limit}",
context.Request.ContentLength, _limits.MaxRequestBytesPerCall);
context.Response.StatusCode = 413; // Payload Too Large
await context.Response.WriteAsJsonAsync(new
{
error = "Payload Too Large",
maxBytes = _limits.MaxRequestBytesPerCall
});
return;
}
}
// Check aggregate capacity
if (!tracker.TryReserve(context.Request.ContentLength ?? 0))
{
context.Response.StatusCode = 503; // Service Unavailable
await context.Response.WriteAsJsonAsync(new
{
error = "Service Overloaded",
message = "Too many concurrent requests"
});
return;
}
try
{
await _next(context);
}
finally
{
tracker.Release(/* bytes actually used */);
}
}
}
```
## IPayloadTracker
```csharp
public interface IPayloadTracker
{
bool TryReserve(long estimatedBytes);
void Release(long actualBytes);
long CurrentInflightBytes { get; }
bool IsOverloaded { get; }
}
internal sealed class PayloadTracker : IPayloadTracker
{
private long _totalInflightBytes;
private readonly ConcurrentDictionary<string, long> _perConnectionBytes = new();
public bool TryReserve(long estimatedBytes)
{
var newTotal = Interlocked.Add(ref _totalInflightBytes, estimatedBytes);
if (newTotal > _limits.MaxAggregateInflightBytes)
{
Interlocked.Add(ref _totalInflightBytes, -estimatedBytes);
return false;
}
return true;
}
public void Release(long actualBytes)
{
Interlocked.Add(ref _totalInflightBytes, -actualBytes);
}
}
```
## ByteCountingStream
```csharp
internal sealed class ByteCountingStream : Stream
{
private readonly Stream _inner;
private readonly long _limit;
private readonly Action _onLimitExceeded;
private long _bytesRead;
public override async ValueTask<int> ReadAsync(Memory<byte> buffer, CancellationToken ct)
{
var read = await _inner.ReadAsync(buffer, ct);
_bytesRead += read;
if (_bytesRead > _limit)
{
_onLimitExceeded();
throw new PayloadLimitExceededException(_bytesRead, _limit);
}
return read;
}
public long BytesRead => _bytesRead;
}
```
## Mid-Stream Limit Breach Flow
```
1. Streaming request begins
2. Gateway counts bytes as they flow through ByteCountingStream
3. When _bytesRead > MaxRequestBytesPerCall:
a. Stop reading from HTTP body
b. Send CANCEL frame with reason "PayloadLimitExceeded"
c. Return 413 to client
d. Log the incident with request details
```
## Configuration
```json
{
"PayloadLimits": {
"MaxRequestBytesPerCall": 10485760,
"MaxRequestBytesPerConnection": 104857600,
"MaxAggregateInflightBytes": 1073741824
}
}
```
## Error Responses
| Condition | HTTP Status | Error Message |
|-----------|-------------|---------------|
| Content-Length exceeds per-call limit | 413 | Payload Too Large |
| Streaming exceeds per-call limit | 413 | Payload Too Large |
| Per-connection limit exceeded | 429 | Too Many Requests |
| Aggregate limit exceeded | 503 | Service Overloaded |
## Exit Criteria
Before marking this sprint DONE:
1. [x] Early rejection for known oversized Content-Length
2. [x] Mid-stream cancellation when limit exceeded
3. [x] CANCEL frame sent on limit breach
4. [x] Per-connection tracking works
5. [x] Aggregate tracking works
6. [x] All limit scenarios tested
7. [x] Metrics/logging in place
## Execution Log
| Date (UTC) | Update | Owner |
|------------|--------|-------|
| 2025-12-05 | Sprint DONE - PayloadTracker, ByteCountingStream, PayloadLimitsMiddleware, PayloadLimitExceededException, 97 tests pass | Claude |
## Decisions & Risks
- Default limits are conservative; tune for your environment
- Per-connection limit applies to inflight bytes, not lifetime total
- Aggregate limit prevents memory exhaustion but may cause 503s under load
- ByteCountingStream adds minimal overhead
- Limit breach is logged at Warning level

## Frame Format
```
┌─────────────────────────────────────────────────────────────┐
│ 4 bytes (big-endian) │ N bytes (payload) │
│ Payload Length │ [FrameType][CorrelationId][Data] │
└─────────────────────────────────────────────────────────────┘
```
### Payload Structure
```
Byte 0: FrameType (1 byte enum value)
Bytes 1-16: CorrelationId (16 bytes GUID)
Bytes 17+: Frame-specific data
```
## TcpTransportServer
```csharp
public sealed class TcpTransportServer : ITransportServer, IAsyncDisposable
{
private TcpListener? _listener;
private readonly ConcurrentDictionary<string, TcpConnection> _connections = new();
public async Task StartAsync(CancellationToken ct)
{
_listener = new TcpListener(_options.BindAddress, _options.Port);
_listener.Start();
_ = AcceptLoopAsync(ct);
}
private async Task AcceptLoopAsync(CancellationToken ct)
{
while (!ct.IsCancellationRequested)
{
var client = await _listener!.AcceptTcpClientAsync(ct);
var connectionId = GenerateConnectionId(client);
var connection = new TcpConnection(connectionId, client, this);
_connections[connectionId] = connection;
OnConnection?.Invoke(connectionId);
_ = connection.ReadLoopAsync(ct);
}
}
public async Task SendFrameAsync(string connectionId, Frame frame)
{
if (_connections.TryGetValue(connectionId, out var conn))
{
await conn.WriteFrameAsync(frame);
}
}
}
```
## TcpConnection (internal)
```csharp
internal sealed class TcpConnection : IAsyncDisposable
{
private readonly TcpClient _client;
private readonly NetworkStream _stream;
private readonly SemaphoreSlim _writeLock = new(1, 1);
public async Task ReadLoopAsync(CancellationToken ct)
{
var lengthBuffer = new byte[4];
while (!ct.IsCancellationRequested)
{
// Read length prefix
await ReadExactAsync(_stream, lengthBuffer, ct);
var length = BinaryPrimitives.ReadInt32BigEndian(lengthBuffer);
// Read payload
var payload = new byte[length];
await ReadExactAsync(_stream, payload, ct);
// Parse frame
var frame = ParseFrame(payload);
_server.OnFrame?.Invoke(_connectionId, frame);
}
}
public async Task WriteFrameAsync(Frame frame)
{
var payload = SerializeFrame(frame);
var lengthBytes = new byte[4];
BinaryPrimitives.WriteInt32BigEndian(lengthBytes, payload.Length);
await _writeLock.WaitAsync();
try
{
await _stream.WriteAsync(lengthBytes);
await _stream.WriteAsync(payload);
}
finally
{
_writeLock.Release();
}
}
}
```
## TcpTransportOptions
```csharp
public sealed class TcpTransportOptions
{
public IPAddress BindAddress { get; set; } = IPAddress.Any;
public int Port { get; set; } = 5100;
public int ReceiveBufferSize { get; set; } = 64 * 1024;
public int SendBufferSize { get; set; } = 64 * 1024;
public TimeSpan KeepAliveInterval { get; set; } = TimeSpan.FromSeconds(30);
public TimeSpan ConnectTimeout { get; set; } = TimeSpan.FromSeconds(10);
public int MaxReconnectAttempts { get; set; } = 10;
public TimeSpan MaxReconnectBackoff { get; set; } = TimeSpan.FromMinutes(1);
}
```
## Multiplexing
One TCP connection carries multiple concurrent requests:
- Each request has unique CorrelationId
- Responses can arrive in any order
- `ConcurrentDictionary<Guid, TaskCompletionSource<Frame>>` for pending requests
```csharp
internal sealed class PendingRequestTracker
{
private readonly ConcurrentDictionary<Guid, TaskCompletionSource<Frame>> _pending = new();
public Task<Frame> TrackRequest(Guid correlationId, CancellationToken ct)
{
var tcs = new TaskCompletionSource<Frame>(TaskCreationOptions.RunContinuationsAsynchronously);
ct.Register(() => tcs.TrySetCanceled());
_pending[correlationId] = tcs;
return tcs.Task;
}
public void CompleteRequest(Guid correlationId, Frame response)
{
if (_pending.TryRemove(correlationId, out var tcs))
{
tcs.TrySetResult(response);
}
}
}
```
## Exit Criteria
Before marking this sprint DONE:
1. [x] TcpTransportServer accepts connections and reads frames
2. [x] TcpTransportClient connects and sends frames
3. [x] Length-prefixed framing works correctly
4. [x] Multiplexing routes responses to correct callers
5. [x] Reconnection with backoff works
6. [x] Keep-alive detects dead connections
7. [x] Integration tests pass
8. [x] Load tests demonstrate concurrent request handling
## Execution Log
| Date (UTC) | Update | Owner |
|------------|--------|-------|
| 2025-12-05 | Sprint DONE - TcpTransportServer, TcpTransportClient, TcpConnection, FrameProtocol, PendingRequestTracker, TcpTransportOptions, ServiceCollectionExtensions, 11 tests pass | Claude |
## Decisions & Risks
- Big-endian length prefix for network byte order
- Maximum frame size: 16 MB (configurable)
- One socket per microservice instance (not per request)
- Write lock prevents interleaved frames
- No compression at transport level (consider adding later)

{
// Server-side (Gateway)
public X509Certificate2? ServerCertificate { get; set; }
public string? ServerCertificatePath { get; set; } // PEM or PFX
public string? ServerCertificateKeyPath { get; set; } // PEM private key
public string? ServerCertificatePassword { get; set; } // For PFX
// Client-side (Microservice)
public X509Certificate2? ClientCertificate { get; set; }
public string? ClientCertificatePath { get; set; }

public string? ExpectedServerHostname { get; set; } // For SNI
// Protocol
public SslProtocols EnabledProtocols { get; set; } = SslProtocols.Tls12 | SslProtocols.Tls13;
}
```
## Server Implementation
```csharp
public sealed class TlsTransportServer : ITransportServer
{
public async Task StartAsync(CancellationToken ct)
{
_listener = new TcpListener(_tcpOptions.BindAddress, _tcpOptions.Port);
_listener.Start();
_ = AcceptLoopAsync(ct);
}
private async Task AcceptLoopAsync(CancellationToken ct)
{
while (!ct.IsCancellationRequested)
{
var tcpClient = await _listener!.AcceptTcpClientAsync(ct);
var sslStream = new SslStream(
tcpClient.GetStream(),
leaveInnerStreamOpen: false,
userCertificateValidationCallback: ValidateClientCertificate);
try
{
await sslStream.AuthenticateAsServerAsync(new SslServerAuthenticationOptions
{
ServerCertificate = _options.ServerCertificate,
ClientCertificateRequired = _options.RequireClientCertificate,
EnabledSslProtocols = _options.EnabledProtocols,
CertificateRevocationCheckMode = _options.CheckCertificateRevocation
? X509RevocationMode.Online
: X509RevocationMode.NoCheck
}, ct);
// Connection authenticated, continue with frame reading
var connectionId = GenerateConnectionId(tcpClient, sslStream.RemoteCertificate);
var connection = new TlsConnection(connectionId, tcpClient, sslStream, this);
_connections[connectionId] = connection;
OnConnection?.Invoke(connectionId);
_ = connection.ReadLoopAsync(ct);
}
catch (AuthenticationException ex)
{
_logger.LogWarning(ex, "TLS handshake failed from {RemoteEndpoint}",
tcpClient.Client.RemoteEndPoint);
tcpClient.Dispose();
}
}
}
private bool ValidateClientCertificate(
object sender, X509Certificate? certificate,
X509Chain? chain, SslPolicyErrors errors)
{
if (!_options.RequireClientCertificate && certificate == null)
return true;
if (_options.AllowSelfSigned)
return true;
return errors == SslPolicyErrors.None;
}
}
```
## Client Implementation
```csharp
public sealed class TlsTransportClient : ITransportClient
{
public async Task ConnectAsync(CancellationToken ct)
{
var tcpClient = new TcpClient();
await tcpClient.ConnectAsync(_options.Host, _options.Port, ct);
var sslStream = new SslStream(
tcpClient.GetStream(),
leaveInnerStreamOpen: false,
userCertificateValidationCallback: ValidateServerCertificate);
await sslStream.AuthenticateAsClientAsync(new SslClientAuthenticationOptions
{
TargetHost = _options.ExpectedServerHostname ?? _options.Host,
ClientCertificates = _options.ClientCertificate != null
? new X509CertificateCollection { _options.ClientCertificate }
: null,
EnabledSslProtocols = _options.EnabledProtocols,
CertificateRevocationCheckMode = _options.CheckCertificateRevocation
? X509RevocationMode.Online
: X509RevocationMode.NoCheck
}, ct);
// Connected and authenticated
_stream = sslStream;
_tcpClient = tcpClient;
}
}
```
## mTLS Identity Extraction
With mTLS, the microservice identity can be verified from the client certificate:
```csharp
internal string ExtractIdentityFromCertificate(X509Certificate2 cert)
{
// Common patterns:
// 1. Common Name (CN)
var cn = cert.GetNameInfo(X509NameType.SimpleName, forIssuer: false);
// 2. Subject Alternative Name (SAN) - DNS or URI
var san = cert.Extensions["2.5.29.17"]; // SAN OID
// 3. Custom extension for service identity
// ...
return cn;
}
```
## Exit Criteria
Before marking this sprint DONE:
1. [x] TlsTransportServer accepts TLS connections
2. [x] TlsTransportClient connects with TLS
3. [x] Server and client certificate configuration works
4. [x] mTLS (mutual TLS) works when enabled
5. [x] Certificate validation works (chain, revocation, hostname)
6. [x] AllowSelfSigned works for dev environments
7. [x] Certificate hot-reload works
8. [x] Integration tests pass
## Execution Log
| Date (UTC) | Update | Owner |
|------------|--------|-------|
| 2025-12-05 | Sprint DONE - TlsTransportServer, TlsTransportClient, TlsConnection, TlsTransportOptions, CertificateLoader, CertificateWatcher, ServiceCollectionExtensions, 12 tests pass | Claude |
## Decisions & Risks
- TLS 1.2 and 1.3 enabled by default (1.0/1.1 disabled)
- Certificate revocation checking is optional (can slow down)
- mTLS is optional (RequireClientCertificate = false by default)
- Identity extraction from cert is customizable
- Certificate hot-reload uses file system watcher

# Sprint 7000-0006-0003 · Real Transports · UDP Plugin
## Topic & Scope
Implement the UDP transport plugin for small, bounded payloads. UDP provides low-latency communication for simple operations but cannot handle streaming or large payloads.
**Goal:** Fast transport for small, idempotent operations.
**Working directory:** `src/__Libraries/StellaOps.Router.Transport.Udp/`
## Dependencies & Concurrency
- **Upstream:** SPRINT_7000_0006_0001 (TCP transport for reference patterns)
- **Downstream:** None.
- **Parallel work:** Can run in parallel with TLS and RabbitMQ sprints.
- **Cross-module impact:** None. New library only.
## Documentation Prerequisites

- `docs/router/09-Step.md` (UDP transport section)
> **BLOCKED Tasks:** Before working on BLOCKED tasks, review [../implplan/BLOCKED_DEPENDENCY_TREE.md](../implplan/BLOCKED_DEPENDENCY_TREE.md) for root blockers and dependencies.

| 24 | UDP-080 | DONE | Write integration tests | |
| 25 | UDP-081 | DONE | Write tests for size limit enforcement | |
## Constraints
From specs.md:
> UDP transport:
> * MUST be used only for small/bounded payloads (no unbounded streaming).
> * MUST respect configured `MaxRequestBytesPerCall`.
- **No streaming:** REQUEST_STREAM_DATA and RESPONSE_STREAM_DATA are not supported
- **Size limit:** Entire request must fit in one datagram
- **Best for:** Ping, health checks, small queries, commands
## Datagram Format
Single UDP datagram = single frame:
```
┌─────────────────────────────────────────────────────────────┐
│ FrameType (1 byte) │ CorrelationId (16 bytes) │ Data (N) │
└─────────────────────────────────────────────────────────────┘
```
Maximum datagram size: Typically 65,507 bytes (IPv4) but practical limit ~1400 for MTU safety.
## UdpTransportServer
```csharp
public sealed class UdpTransportServer : ITransportServer
{
private UdpClient? _listener;
private readonly ConcurrentDictionary<IPEndPoint, string> _endpointToConnectionId = new();
public async Task StartAsync(CancellationToken ct)
{
_listener = new UdpClient(_options.Port);
_ = ReceiveLoopAsync(ct);
}
private async Task ReceiveLoopAsync(CancellationToken ct)
{
while (!ct.IsCancellationRequested)
{
var result = await _listener!.ReceiveAsync(ct);
var remoteEndpoint = result.RemoteEndPoint;
var data = result.Buffer;
// Parse frame
var frame = ParseFrame(data);
// Get or create connection ID for this endpoint
var connectionId = _endpointToConnectionId.GetOrAdd(
remoteEndpoint,
ep => $"udp-{ep}");
// Handle HELLO specially to register connection
if (frame.Type == FrameType.Hello)
{
OnConnection?.Invoke(connectionId);
}
OnFrame?.Invoke(connectionId, frame);
}
}
public async Task SendFrameAsync(string connectionId, Frame frame)
{
var endpoint = ResolveEndpoint(connectionId);
var data = SerializeFrame(frame);
if (data.Length > _options.MaxDatagramSize)
throw new PayloadTooLargeException(data.Length, _options.MaxDatagramSize);
await _listener!.SendAsync(data, data.Length, endpoint);
}
}
```
## UdpTransportClient
```csharp
public sealed class UdpTransportClient : ITransportClient
{
private UdpClient? _client;
private readonly ConcurrentDictionary<Guid, TaskCompletionSource<Frame>> _pending = new();
public async Task ConnectAsync(string host, int port, CancellationToken ct)
{
_client = new UdpClient();
_client.Connect(host, port);
_ = ReceiveLoopAsync(ct);
}
public async Task<Frame> SendRequestAsync(
ConnectionState connection, Frame request,
TimeSpan timeout, CancellationToken ct)
{
var data = SerializeFrame(request);
if (data.Length > _options.MaxDatagramSize)
throw new PayloadTooLargeException(data.Length, _options.MaxDatagramSize);
var tcs = new TaskCompletionSource<Frame>();
using var cts = CancellationTokenSource.CreateLinkedTokenSource(ct);
cts.CancelAfter(timeout);
cts.Token.Register(() => tcs.TrySetCanceled());
_pending[request.CorrelationId] = tcs;
await _client!.SendAsync(data, data.Length);
return await tcs.Task;
}
// Streaming not supported
public Task SendStreamingAsync(...) => throw new NotSupportedException(
"UDP transport does not support streaming. Use TCP or TLS transport.");
}
```
## UdpTransportOptions
```csharp
public sealed class UdpTransportOptions
{
public IPAddress BindAddress { get; set; } = IPAddress.Any;
public int Port { get; set; } = 5101;
public int MaxDatagramSize { get; set; } = 8192; // Conservative default
public TimeSpan DefaultTimeout { get; set; } = TimeSpan.FromSeconds(5);
public bool AllowBroadcast { get; set; } = false;
}
```
## Use Cases
UDP is appropriate for:
- **Health checks:** Small, frequent, non-critical
- **Metrics collection:** Fire-and-forget updates
- **Cache invalidation:** Small notifications
- **DNS-like lookups:** Quick request/response
UDP is NOT appropriate for:
- **File uploads/downloads:** Requires streaming
- **Large requests/responses:** Exceeds datagram limit
- **Critical operations:** No delivery guarantee
- **Ordered sequences:** Out-of-order possible
## Exit Criteria
Before marking this sprint DONE:
1. [x] UdpTransportServer receives datagrams
2. [x] UdpTransportClient sends and receives
3. [x] Size limits enforced
4. [x] Streaming disabled/rejected
5. [x] Request/response correlation works
6. [x] Integration tests pass
## Execution Log
| Date (UTC) | Update | Owner |
|------------|--------|-------|
| 2025-12-05 | Sprint DONE - UdpTransportServer, UdpTransportClient, UdpFrameProtocol, UdpTransportOptions, PayloadTooLargeException, ServiceCollectionExtensions, 13 tests pass | Claude |
## Decisions & Risks
- Default max datagram: 8KB (well under MTU)
- No retry/reliability - UDP is fire-and-forget
- Connection is logical (based on source IP:port)
- Timeout is per-request, no keepalive needed
- CANCEL is sent but may not arrive (best effort)

// Naming
public string ExchangePrefix { get; set; } = "stella.router";
public string QueuePrefix { get; set; } = "stella";
}
```
## RabbitMqTransportServer
```csharp
public sealed class RabbitMqTransportServer : ITransportServer
{
private IConnection? _connection;
private IModel? _channel;
private readonly string _requestQueueName;
public async Task StartAsync(CancellationToken ct)
{
var factory = new ConnectionFactory
{
HostName = _options.HostName,
Port = _options.Port,
VirtualHost = _options.VirtualHost,
UserName = _options.UserName,
Password = _options.Password
};
_connection = factory.CreateConnection();
_channel = _connection.CreateModel();
// Declare exchanges
_channel.ExchangeDeclare(_options.RequestExchange, ExchangeType.Direct, durable: true);
_channel.ExchangeDeclare(_options.ResponseExchange, ExchangeType.Topic, durable: true);

exclusive: false,
autoDelete: _options.AutoDeleteQueues);
_channel.QueueBind(_requestQueueName, _options.RequestExchange, routingKey: _nodeId);

var consumer = new EventingBasicConsumer(_channel);
consumer.Received += OnMessageReceived;
_channel.BasicConsume(_requestQueueName, autoAck: true, consumer);
}
private void OnMessageReceived(object? sender, BasicDeliverEventArgs e)
{
var frame = ParseFrame(e.Body.ToArray(), e.BasicProperties);
var connectionId = ExtractConnectionId(e.BasicProperties);
if (frame.Type == FrameType.Hello)
{
OnConnection?.Invoke(connectionId);
}
OnFrame?.Invoke(connectionId, frame);
}
}
```
## At-Most-Once Semantics
From specs.md:
> * Guarantee at-most-once semantics where practical.
This means:
- Auto-ack messages (no redelivery on failure)
- Non-durable queues/messages by default
- Idempotent handlers are caller's responsibility
For at-least-once (if needed later):
- Manual ack after processing
- Durable queues and persistent messages
- Deduplication in handler
## Exit Criteria
Before marking this sprint DONE:
1. [ ] RabbitMqTransportServer connects and consumes
2. [ ] RabbitMqTransportClient publishes and consumes
3. [ ] Queue/exchange topology correct
4. [ ] CorrelationId matching works
5. [ ] HELLO/HEARTBEAT/REQUEST/RESPONSE flow works
6. [ ] Connection recovery works
7. [ ] Integration tests pass with local RabbitMQ
## Execution Log
| Date (UTC) | Update | Owner |
|------------|--------|-------|
| 2025-12-05 | Code DONE but BLOCKED - RabbitMQ.Client NuGet package not available in local-nugets. Code written: RabbitMqTransportServer, RabbitMqTransportClient, RabbitMqFrameProtocol, RabbitMqTransportOptions, ServiceCollectionExtensions | Claude |
## Decisions & Risks
- Auto-delete queues by default (clean up on disconnect)
- Non-persistent messages by default (speed over durability)
- Prefetch count limits concurrent processing
- Connection recovery uses RabbitMQ.Client built-in recovery
- Streaming is optional (throws NotSupportedException for simplicity)
- **BLOCKED:** RabbitMQ.Client 7.0.0 needs to be added to local-nugets folder for build to succeed

## RouterConfig Structure
```csharp
public sealed class RouterConfig
{
public IList<ServiceConfig> Services { get; init; } = new List<ServiceConfig>();
public IList<StaticInstanceConfig> StaticInstances { get; init; } = new List<StaticInstanceConfig>();
public PayloadLimits PayloadLimits { get; init; } = new();
public RoutingOptions Routing { get; init; } = new();
}
public sealed class ServiceConfig
{
public string Name { get; init; } = string.Empty;
public string DefaultVersion { get; init; } = "1.0.0";
public TransportType DefaultTransport { get; init; } = TransportType.Tcp;
public IList<EndpointConfig> Endpoints { get; init; } = new List<EndpointConfig>();
}
public sealed class EndpointConfig
{

}
```
## Sample router.yaml
```yaml
# Router configuration
payloadLimits:
maxRequestBytesPerCall: 10485760 # 10 MB
maxRequestBytesPerConnection: 104857600
maxAggregateInflightBytes: 1073741824
routing:
neighborRegions:
- eu2

services:
- name: billing
defaultVersion: "1.0.0"
defaultTransport: tcp
endpoints:
- method: POST
path: /invoices
defaultTimeout: 30s
requiringClaims:
- type: role
value: billing-admin
- method: GET
path: /invoices/{id}
defaultTimeout: 5s
- name: inventory
defaultVersion: "2.1.0"
defaultTransport: tls

# Optional: static instances (usually discovered via HELLO)
staticInstances:
- serviceName: billing
version: "1.0.0"
region: eu1
host: billing-eu1-01.internal
port: 5100
transport: tcp
```
## Hot-Reload Implementation
```csharp
public sealed class RouterConfigProvider : IRouterConfigProvider, IDisposable
{
private RouterConfig _current;
private readonly FileSystemWatcher? _watcher;
private readonly ILogger<RouterConfigProvider> _logger;
public RouterConfigProvider(IOptions<RouterConfigOptions> options, ILogger<RouterConfigProvider> logger)
{
_logger = logger;
_current = LoadConfig(options.Value.ConfigPath);
if (options.Value.EnableHotReload)
{
_watcher = new FileSystemWatcher(Path.GetDirectoryName(options.Value.ConfigPath)!)
{
Filter = Path.GetFileName(options.Value.ConfigPath),
NotifyFilter = NotifyFilters.LastWrite
};
_watcher.Changed += OnConfigFileChanged;
_watcher.EnableRaisingEvents = true;
}
}
private void OnConfigFileChanged(object sender, FileSystemEventArgs e)
{
try
{
var newConfig = LoadConfig(e.FullPath);
ValidateConfig(newConfig);
var previous = _current;
_current = newConfig;
_logger.LogInformation("Router configuration reloaded successfully");
ConfigurationChanged?.Invoke(this, new ConfigChangedEventArgs(previous, newConfig));
}
catch (Exception ex)
{
_logger.LogError(ex, "Failed to reload configuration, keeping previous");
}
}
public RouterConfig Current => _current;
public event EventHandler<ConfigChangedEventArgs>? ConfigurationChanged;
}
```
## Configuration Precedence
1. **Code defaults** (in Common library)
2. **YAML configuration** (router.yaml)
3. **JSON configuration** (appsettings.json)
4. **Environment variables** (STELLAOPS_ROUTER_*)
5. **Microservice HELLO** (dynamic registration)
6. **Authority overrides** (for RequiringClaims)
Later sources override earlier ones.
## Exit Criteria
Before marking this sprint DONE:
1. [x] RouterConfig binds from YAML correctly
2. [x] JSON and environment variables also work
3. [x] Hot-reload updates config without restart
4. [x] Validation rejects invalid config
5. [x] Sample router.yaml documents all options
6. [x] DI integration works with Gateway
## Execution Log
| Date (UTC) | Update | Owner |
|------------|--------|-------|
| 2025-12-05 | Sprint DONE - Implemented RouterConfig, ServiceConfig, EndpointConfig, StaticInstanceConfig, RoutingOptions, RouterConfigOptions, IRouterConfigProvider, RouterConfigProvider with hot-reload, ServiceCollectionExtensions. Created etc/router.yaml.sample. 15 tests passing. | Claude |
## Decisions & Risks
- YamlDotNet for YAML parsing (mature, well-supported)
- File watcher has debounce to avoid multiple reloads
- Invalid hot-reload keeps previous config (fail-safe)
- Static instances are optional (most discover via HELLO)

# Sprint 7000-0007-0002 · Configuration · Microservice YAML Config
## Topic & Scope
Implement YAML configuration support for microservices. Allows endpoint-level overrides for timeouts, RequiringClaims, and streaming flags without code changes.
**Goal:** Microservices can customize endpoint behavior via YAML without rebuilding.
**Working directory:** `src/__Libraries/StellaOps.Microservice/`
## Dependencies & Concurrency
- **Upstream:** SPRINT_7000_0007_0001 (Router.Config patterns)
- **Downstream:** SPRINT_7000_0008_0001 (Authority integration)
- **Parallel work:** None. Sequential.
- **Cross-module impact:** Microservice SDK only.
## Documentation Prerequisites
- `docs/router/specs.md` (sections 7.3, 11 - Microservice config requirements)
- `docs/router/10-Step.md` (microservice YAML section)
> **BLOCKED Tasks:** Before working on BLOCKED tasks, review [../implplan/BLOCKED_DEPENDENCY_TREE.md](../implplan/BLOCKED_DEPENDENCY_TREE.md) for root blockers and dependencies.

## MicroserviceYamlConfig Structure
```csharp
public sealed class MicroserviceYamlConfig
{
public IList<EndpointOverrideConfig> Endpoints { get; init; } = new List<EndpointOverrideConfig>();
}
public sealed class EndpointOverrideConfig
{
public string Method { get; init; } = string.Empty;
public string Path { get; init; } = string.Empty;
public TimeSpan? DefaultTimeout { get; init; }
public bool? SupportsStreaming { get; init; }
public IList<ClaimRequirementConfig>? RequiringClaims { get; init; }
}
```
## Sample microservice.yaml
```yaml
# Microservice endpoint overrides
# Note: Only modifies endpoints declared in code; cannot create new endpoints
endpoints:
- method: POST
path: /invoices
defaultTimeout: 60s # Override code default of 30s
requiringClaims:
- type: role
value: invoice-creator
- type: department
value: finance
- method: GET
path: /invoices/{id}
defaultTimeout: 10s
- method: POST
path: /reports/generate
supportsStreaming: true # Enable streaming for large reports
defaultTimeout: 300s # 5 minutes for long-running reports
```
## Merge Logic
```csharp
internal sealed class EndpointOverrideMerger
{
public EndpointDescriptor Merge(
EndpointDescriptor codeDefault,
EndpointOverrideConfig? yamlOverride)
{
if (yamlOverride == null)
return codeDefault;
return codeDefault with
{
DefaultTimeout = yamlOverride.DefaultTimeout ?? codeDefault.DefaultTimeout,
SupportsStreaming = yamlOverride.SupportsStreaming ?? codeDefault.SupportsStreaming,
RequiringClaims = yamlOverride.RequiringClaims?.Select(c =>
new ClaimRequirement { Type = c.Type, Value = c.Value }).ToList()
?? codeDefault.RequiringClaims
};
}
}
```
## Precedence Rules
From specs.md section 7.3:
> Precedence rules MUST be clearly defined and honored:
> * Service identity & router pool: from `StellaMicroserviceOptions` (not YAML).
> * Endpoint set: from code (attributes/source gen); YAML MAY override properties but ideally not create endpoints not present in code.
> * `RequiringClaims` and timeouts: YAML overrides defaults from code, unless overridden by central Authority.
```
┌─────────────────┐
│ Code defaults │ [StellaEndpoint] attribute values
└────────┬────────┘
│ YAML overrides (if present)
▼
┌─────────────────┐
│ YAML config │ Endpoint-specific overrides
└────────┬────────┘
│ Authority overrides (later sprint)
▼
┌─────────────────┐
│ Effective │ Final values sent in HELLO
└─────────────────┘
```
## Integration with Discovery
```csharp
internal sealed class EndpointDiscoveryService
{
private readonly IMicroserviceYamlLoader _yamlLoader;
private readonly EndpointOverrideMerger _merger;
public IReadOnlyList<EndpointDescriptor> DiscoverEndpoints()
{
// 1. Discover from code
var codeEndpoints = DiscoverFromReflection();
// 2. Load YAML overrides
var yamlConfig = _yamlLoader.Load();
// 3. Merge
return codeEndpoints.Select(ep =>
{
var yamlOverride = yamlConfig?.Endpoints
.FirstOrDefault(y => y.Method == ep.Method && y.Path == ep.Path);
if (yamlOverride == null)
return ep;
return _merger.Merge(ep, yamlOverride);
}).ToList();
}
}
```
## Warning on Unmatched YAML
```csharp
private void WarnUnmatchedOverrides(
IEnumerable<EndpointDescriptor> codeEndpoints,
MicroserviceYamlConfig? yamlConfig)
{
if (yamlConfig == null) return;
var codeKeys = codeEndpoints.Select(e => (e.Method, e.Path)).ToHashSet();
foreach (var yamlEntry in yamlConfig.Endpoints)
{
if (!codeKeys.Contains((yamlEntry.Method, yamlEntry.Path)))
{
_logger.LogWarning(
"YAML override for {Method} {Path} does not match any code endpoint",
yamlEntry.Method, yamlEntry.Path);
}
}
}
```
## Exit Criteria
Before marking this sprint DONE:
1. [x] YAML loading works from ConfigFilePath
2. [x] Merge applies YAML overrides to code defaults
3. [x] Precedence is code → YAML
4. [x] Unmatched YAML entries logged as warnings
5. [x] Sample microservice.yaml documented
6. [x] Unit tests for merge logic
## Execution Log
| Date (UTC) | Update | Owner |
|------------|--------|-------|
| 2025-12-05 | Sprint completed. 85 tests pass. | Claude |
## Decisions & Risks
- YAML cannot create endpoints (only modify) per spec
- Missing YAML file is not an error (optional config)
- Hot-reload of microservice YAML is not supported (restart required)
- RequiringClaims in YAML fully replaces code defaults (not merged)

# Sprint 7000-0008-0001 · Integration · Authority Claims Override
## Topic & Scope
Implement Authority integration for RequiringClaims overrides. The central Authority service can push endpoint authorization requirements that override microservice defaults.
**Goal:** Centralized authorization policy that takes precedence over microservice-defined claims.
**Working directories:**
- `src/Gateway/StellaOps.Gateway.WebService/` (apply overrides)
- `src/Authority/` (if Authority changes needed)
## Dependencies & Concurrency
- **Upstream:** SPRINT_7000_0007_0002 (microservice YAML - establishes precedence)
- **Downstream:** SPRINT_7000_0008_0002 (source generator)
- **Parallel work:** Can run in parallel with source generator sprint.
- **Cross-module impact:** May require Authority module changes.
## Documentation Prerequisites
- `docs/router/specs.md` (section 9 - Authorization / requiringClaims / Authority requirements)
- `docs/modules/authority/architecture.md` (Authority module design)
> **BLOCKED Tasks:** Before working on BLOCKED tasks, review [../implplan/BLOCKED_DEPENDENCY_TREE.md](../implplan/BLOCKED_DEPENDENCY_TREE.md) for root blockers and dependencies.

IReadOnlyList<ClaimRequirement> GetEffectiveClaims(
string serviceName, string method, string path);
void UpdateFromMicroservice(string serviceName, IReadOnlyList<EndpointDescriptor> endpoints);
void UpdateFromAuthority(IReadOnlyDictionary<EndpointKey, IReadOnlyList<ClaimRequirement>> overrides);
}
internal sealed class EffectiveClaimsStore : IEffectiveClaimsStore
{
private readonly ConcurrentDictionary<EndpointKey, IReadOnlyList<ClaimRequirement>> _microserviceClaims = new();
private readonly ConcurrentDictionary<EndpointKey, IReadOnlyList<ClaimRequirement>> _authorityClaims = new();
public IReadOnlyList<ClaimRequirement> GetEffectiveClaims(
string serviceName, string method, string path)
{
var key = new EndpointKey(serviceName, method, path);
// Authority takes precedence
if (_authorityClaims.TryGetValue(key, out var authorityClaims))
return authorityClaims;
// Fall back to microservice defaults
if (_microserviceClaims.TryGetValue(key, out var msClaims))
return msClaims;
return Array.Empty<ClaimRequirement>();
}
}
```
## Authority Connection Options
```csharp
public sealed class AuthorityConnectionOptions
{
public string AuthorityUrl { get; set; } = string.Empty;
public bool WaitForAuthorityOnStartup { get; set; } = true;
public TimeSpan StartupTimeout { get; set; } = TimeSpan.FromSeconds(30);
public TimeSpan RefreshInterval { get; set; } = TimeSpan.FromMinutes(5);
public bool UseAuthorityPushNotifications { get; set; } = false;
}
```
## Exit Criteria
Before marking this sprint DONE:
1. [x] IAuthorityClaimsProvider implemented
2. [x] Gateway fetches overrides on startup
3. [x] Authority overrides take precedence
4. [x] AuthorizationMiddleware enforces effective claims
5. [x] Graceful handling when Authority unavailable
6. [x] Integration tests verify claims enforcement
## Execution Log
| Date (UTC) | Update | Owner |
|------------|--------|-------|
| 2025-12-05 | Implemented IAuthorityClaimsProvider, IEffectiveClaimsStore, EffectiveClaimsStore | Claude |
| 2025-12-05 | Implemented HttpAuthorityClaimsProvider with HTTP client | Claude |
| 2025-12-05 | Implemented AuthorityClaimsRefreshService background service | Claude |
| 2025-12-05 | Implemented AuthorizationMiddleware with claims enforcement | Claude |
| 2025-12-05 | Created AuthorityConnectionOptions for configuration | Claude |
| 2025-12-05 | Added NoOpAuthorityClaimsProvider for disabled mode | Claude |
| 2025-12-05 | Created 19 tests for EffectiveClaimsStore and AuthorizationMiddleware | Claude |
| 2025-12-05 | All tests passing - sprint DONE | Claude |
## Decisions & Risks
- Authority overrides fully replace microservice claims (not merged)
- Startup can optionally wait for Authority (fail-safe mode proceeds without)
- Refresh interval is 5 minutes by default (tune for your environment)
- Authority push notifications optional (polling is default)
- This sprint assumes Authority module exists; coordinate with Authority team

## Source Generator Output
Given this input:
```csharp
[StellaEndpoint("POST", "/invoices", DefaultTimeout = 30)]
public sealed class CreateInvoiceEndpoint : IStellaEndpoint<CreateInvoiceRequest, CreateInvoiceResponse>
{
public Task<CreateInvoiceResponse> HandleAsync(CreateInvoiceRequest request, CancellationToken ct) => ...;
}
```
The generator produces:
```csharp
// <auto-generated/>
namespace StellaOps.Microservice.Generated
{
[global::System.CodeDom.Compiler.GeneratedCode("StellaOps.Microservice.SourceGen", "1.0.0")]
internal static class StellaEndpoints
{
public static global::System.Collections.Generic.IReadOnlyList<global::StellaOps.Router.Common.EndpointDescriptor>
GetEndpoints()
{
return new global::StellaOps.Router.Common.EndpointDescriptor[]
{
new global::StellaOps.Router.Common.EndpointDescriptor
{
Method = "POST",
Path = "/invoices",
DefaultTimeout = global::System.TimeSpan.FromSeconds(30),
SupportsStreaming = false,
RequiringClaims = global::System.Array.Empty<global::StellaOps.Router.Common.ClaimRequirement>(),
HandlerType = typeof(global::MyApp.CreateInvoiceEndpoint)
},
// ... more endpoints
};
}
public static void RegisterHandlers(
global::Microsoft.Extensions.DependencyInjection.IServiceCollection services)
{
services.AddTransient<global::MyApp.CreateInvoiceEndpoint>();
// ... more handlers
}
}
}
```
## Generator Implementation
```csharp
[Generator]
public class StellaEndpointGenerator : IIncrementalGenerator
{
public void Initialize(IncrementalGeneratorInitializationContext context)
{
// Find all classes with [StellaEndpoint]
var endpointClasses = context.SyntaxProvider
.ForAttributeWithMetadataName(
"StellaOps.Microservice.StellaEndpointAttribute",
predicate: static (node, _) => node is ClassDeclarationSyntax,
transform: static (ctx, _) => GetEndpointInfo(ctx))
.Where(static info => info is not null);
// Combine and generate
context.RegisterSourceOutput(
endpointClasses.Collect(),
static (spc, endpoints) => GenerateEndpointsClass(spc, endpoints!));
}
private static EndpointInfo? GetEndpointInfo(GeneratorAttributeSyntaxContext context)
{
var classSymbol = (INamedTypeSymbol)context.TargetSymbol;
var attribute = context.Attributes[0];
// Extract attribute parameters
var method = attribute.ConstructorArguments[0].Value as string;
var path = attribute.ConstructorArguments[1].Value as string;
// Find timeout, streaming, etc. from named arguments
var timeout = attribute.NamedArguments
.FirstOrDefault(a => a.Key == "DefaultTimeout").Value.Value as int? ?? 30;
// Verify handler interface
var implementsHandler = classSymbol.AllInterfaces
.Any(i => i.Name.StartsWith("IStellaEndpoint"));
if (!implementsHandler)
{
// Report diagnostic
return null;
}
return new EndpointInfo(classSymbol, method!, path!, timeout);
}
}
```
## IGeneratedEndpointProvider
```csharp
public interface IGeneratedEndpointProvider
{
IReadOnlyList<EndpointDescriptor> GetEndpoints();
void RegisterHandlers(IServiceCollection services);
}
// Generated implementation
internal sealed class GeneratedEndpointProvider : IGeneratedEndpointProvider
{
public IReadOnlyList<EndpointDescriptor> GetEndpoints()
=> StellaEndpoints.GetEndpoints();
public void RegisterHandlers(IServiceCollection services)
=> StellaEndpoints.RegisterHandlers(services);
}
```
## SDK Integration
```csharp
internal sealed class EndpointDiscoveryService
{
public IReadOnlyList<EndpointDescriptor> DiscoverEndpoints()
{
// Prefer generated
var generated = TryGetGeneratedProvider();
if (generated != null)
{
_logger.LogDebug("Using source-generated endpoint discovery");
return generated.GetEndpoints();
}
// Fall back to reflection
_logger.LogDebug("Using reflection-based endpoint discovery");
return DiscoverFromReflection();
}
private IGeneratedEndpointProvider? TryGetGeneratedProvider()
{
// Look for generated type in entry assembly
var entryAssembly = Assembly.GetEntryAssembly();
var providerType = entryAssembly?.GetType(
"StellaOps.Microservice.Generated.GeneratedEndpointProvider");
if (providerType != null)
return (IGeneratedEndpointProvider)Activator.CreateInstance(providerType)!;
return null;
}
}
```
## Diagnostics
| ID | Severity | Message |
|----|----------|---------|
| STELLA001 | Error | Class with [StellaEndpoint] must implement IStellaEndpoint<> or IRawStellaEndpoint |
| STELLA002 | Warning | Duplicate endpoint: {Method} {Path} |
| STELLA003 | Warning | [StellaEndpoint] on abstract class is ignored |
| STELLA004 | Info | Generated {N} endpoint descriptors |
## Exit Criteria
Before marking this sprint DONE:
1. [x] Source generator detects [StellaEndpoint] classes
2. [x] Generates EndpointDescriptor array
3. [x] Generates DI registration
4. [x] Incremental generation for fast builds
5. [x] Analyzers report invalid usage
6. [x] SDK prefers generated over reflection
7. [x] All tests pass
## Execution Log
| Date (UTC) | Update | Owner |
|------------|--------|-------|
| 2025-12-05 | Converted project to Roslyn source generator (netstandard2.0) | Claude |
| 2025-12-05 | Implemented StellaEndpointGenerator with incremental pipeline | Claude |
| 2025-12-05 | Added diagnostic descriptors STELLA001-004 | Claude |
| 2025-12-05 | Added IGeneratedEndpointProvider interface | Claude |
| 2025-12-05 | Created GeneratedEndpointDiscoveryProvider (prefers generated) | Claude |
| 2025-12-05 | Updated SDK to use generated provider by default | Claude |
| 2025-12-05 | All 85 microservice tests pass - sprint DONE | Claude |
## Decisions & Risks
- Incremental generation is essential for large projects
- Generated code uses fully qualified names to avoid conflicts
- Fallback to reflection ensures compatibility with older projects
- AOT scenarios require source generation (no reflection)

CreateInvoiceRequest request,
CancellationToken ct)
{
var invoice = await _service.CreateAsync(request, ct);
return new CreateInvoiceResponse { InvoiceId = invoice.Id };
}
}
```
### Streaming Endpoint
```csharp
[StellaEndpoint("POST", "/invoices/{id}/attachments", SupportsStreaming = true)]
public sealed class UploadAttachmentEndpoint : IRawStellaEndpoint
{
private readonly IStorageService _storage;
public async Task<RawResponse> HandleAsync(RawRequestContext context, CancellationToken ct)
{
var invoiceId = context.PathParameters["id"];
// Stream body directly to storage
var path = await _storage.StoreAsync(invoiceId, context.Body, ct);

## Migration Strategies
### Strategy A: In-Place Adaptation
Best for: Services that need to maintain HTTP compatibility during transition.
```
┌─────────────────────────────────────┐
│ StellaOps.Billing.WebService │
│ ┌─────────────────────────────┐ │
│ │ Existing HTTP Controllers │◄───┼──── HTTP clients (legacy)
│ └─────────────────────────────┘ │
│ ┌─────────────────────────────┐ │
│ │ [StellaEndpoint] Handlers │◄───┼──── Router (new)
│ └─────────────────────────────┘ │
│ ┌─────────────────────────────┐ │
│ │ Shared Domain Logic │ │
│ └─────────────────────────────┘ │
└─────────────────────────────────────┘
```
Steps:
1. Add `StellaOps.Microservice` package reference
2. Create handler classes for each route
3. Handlers call existing service layer
4. Register with router pool
5. Test via router
6. Shift traffic gradually
7. Remove HTTP controllers when ready
### Strategy B: Clean Split
Best for: Major refactoring or when HTTP compatibility not needed.
```
┌─────────────────────────────────────┐
│ StellaOps.Billing.Domain │ ◄── Shared library
│ (extracted business logic) │
└─────────────────────────────────────┘
▲ ▲
│ │
┌─────────┴───────┐ ┌───────┴─────────┐
│ (Legacy) │ │ (New) │
│ Billing.Web │ │ Billing.Micro │
│ Service │ │ service │
│ HTTP only │ │ Router only │
└─────────────────┘ └─────────────────┘
```
Steps:
1. Extract domain logic to `.Domain` library
2. Create new `.Microservice` project
3. Implement handlers using domain library
4. Deploy alongside WebService
5. Shift traffic to router
6. Deprecate WebService
## Controller to Handler Mapping
### Before (ASP.NET Controller)
```csharp
[ApiController]
[Route("api/invoices")]
public class InvoicesController : ControllerBase
{
private readonly IInvoiceService _service;
[HttpPost]
[Authorize(Roles = "billing-admin")]
public async Task<IActionResult> Create(
[FromBody] CreateInvoiceRequest request,
CancellationToken ct) // <-- Often missing!
{
var invoice = await _service.CreateAsync(request);
return Ok(new { invoice.Id });
}
}
```
### After (Microservice Handler)
```csharp
[StellaEndpoint("POST", "/api/invoices")]
public sealed class CreateInvoiceEndpoint : IStellaEndpoint<CreateInvoiceRequest, CreateInvoiceResponse>
{
private readonly IInvoiceService _service;
public CreateInvoiceEndpoint(IInvoiceService service) => _service = service;
public async Task<CreateInvoiceResponse> HandleAsync(
CreateInvoiceRequest request,
CancellationToken ct) // <-- Required, propagated
{
var invoice = await _service.CreateAsync(request, ct); // Pass token!
return new CreateInvoiceResponse { InvoiceId = invoice.Id };
}
}
```
## CancellationToken Checklist
For each migrated handler, verify:
- [ ] Handler accepts CancellationToken parameter
- [ ] Token passed to all database calls
- [ ] Token passed to all HTTP client calls
- [ ] Token passed to all file I/O operations
- [ ] Long-running loops check `ct.IsCancellationRequested`
- [ ] Token passed to Task.Delay, WaitAsync, etc.
## Streaming Migration
### File Upload (Before)
```csharp
[HttpPost("upload")]
public async Task<IActionResult> Upload(IFormFile file)
{
using var stream = file.OpenReadStream();
await _storage.SaveAsync(stream);
return Ok();
}
```
### File Upload (After)
```csharp
[StellaEndpoint("POST", "/upload", SupportsStreaming = true)]
public sealed class UploadEndpoint : IRawStellaEndpoint
{
public async Task<RawResponse> HandleAsync(RawRequestContext ctx, CancellationToken ct)
{
await _storage.SaveAsync(ctx.Body, ct); // Body is already a stream
return RawResponse.Ok();
}
}
```
## Migration Checklist Template
```markdown
# Migration Checklist: [ServiceName]
## Inventory
- [ ] List all HTTP routes (Method + Path)
- [ ] Identify streaming endpoints
- [ ] Identify authorization requirements
- [ ] Document external dependencies
## Preparation
- [ ] Add StellaOps.Microservice package
- [ ] Configure router connection
- [ ] Set up local gateway for testing
## Per-Route Migration
For each route:
- [ ] Create [StellaEndpoint] handler class
- [ ] Map request/response types
- [ ] Wire CancellationToken throughout
- [ ] Convert to IRawStellaEndpoint if streaming
- [ ] Write unit tests
- [ ] Write integration tests
## Cutover
- [ ] Deploy alongside existing WebService
- [ ] Verify via router routing
- [ ] Shift percentage of traffic
- [ ] Monitor for errors
- [ ] Full cutover
- [ ] Remove WebService HTTP listeners
## Cleanup
- [ ] Remove unused controller code
- [ ] Remove HTTP pipeline configuration
- [ ] Update documentation
```
## StellaOps Modules to Migrate
| Module | WebService | Priority | Complexity |
|--------|------------|----------|------------|
| Concelier | StellaOps.Concelier.WebService | High | Medium |
| Scanner | StellaOps.Scanner.WebService | High | High (streaming) |
| Authority | StellaOps.Authority.WebService | Medium | Low |
| Orchestrator | StellaOps.Orchestrator.WebService | Medium | Medium |
| Scheduler | StellaOps.Scheduler.WebService | Low | Low |
| Notify | StellaOps.Notify.WebService | Low | Low |
## Exit Criteria
Before marking this sprint DONE:
1. [x] Migration strategies documented (migration-guide.md)
2. [x] Controller-to-handler mapping guide complete (migration-guide.md)
3. [x] CancellationToken checklist complete (migration-guide.md)
4. [x] Streaming migration guide complete (migration-guide.md)
5. [x] Migration checklist template created (migration-guide.md)
6. [~] Pilot migration executed successfully (deferred to team for actual service migration)
7. [x] Router.sln merged into StellaOps.sln
8. [x] CI/CD updated (build-test-deploy.yml)
## Execution Log
| Date (UTC) | Update | Owner |
|------------|--------|-------|
| 2024-12-04 | Created comprehensive migration-guide.md with strategies, examples, and service inventory | Claude |
| 2024-12-04 | Added all Router projects to StellaOps.sln (Microservice SDK, Config, Transports) | Claude |
| 2024-12-04 | Updated build-test-deploy.yml with Router component build and test steps | Claude |
## Decisions & Risks
- Pilot migration should be a low-risk service first
- Strategy A preferred for gradual transition
- Strategy B preferred for greenfield-like rewrites
- CancellationToken wiring is the #1 source of migration bugs
- Streaming endpoints require IRawStellaEndpoint, not typed handlers
- Authorization migrates from [Authorize(Roles)] to RequiringClaims

2. [ ] RabbitMq transport has comprehensive unit tests (critical gap closed)
3. [ ] Router.Common coverage > 90% for FrameConverter, PathMatcher
4. [ ] Router.Config coverage > 85% for RouterConfigProvider
5. [ ] All tests follow AAA pattern with comments
6. [ ] Integration tests demonstrate end-to-end flows
7. [ ] All tests added to CI/CD workflow
## Execution Log
| Date (UTC) | Update | Owner |
|------------|--------|-------|
| | | |
## Decisions & Risks
- All new test projects in `src/__Libraries/__Tests/` following existing pattern
- RabbitMQ unit tests use mocked interfaces (no real broker required)
- Integration tests may use Testcontainers for real broker testing
- xUnit v3 with FluentAssertions 6.12.0
- Test naming: `[Method]_[Scenario]_[Expected]`

## Critical Path
The minimum path to a working router:
1. **7000-0001-0001** → Skeleton
2. **7000-0001-0002** → Common models
3. **7000-0002-0001** → InMemory transport
4. **7000-0003-0001** → SDK core
5. **7000-0003-0002** → SDK handlers
6. **7000-0004-0001** → Gateway core
7. **7000-0004-0002** → Gateway middleware
8. **7000-0004-0003** → Gateway connections
After these 8 sprints, you have a working router with InMemory transport for testing.
## Isolation Strategy
The router is developed in isolation using:
1. **Separate solution file:** `StellaOps.Router.sln`
2. **Dedicated directories:** All router code in new directories
3. **No changes to existing modules:** Until migration sprint
4. **InMemory transport first:** No network dependencies during core development
This ensures:
- Router development doesn't impact existing StellaOps builds
- Agents can work independently on router without merge conflicts
- Full testing possible without real infrastructure
- Migration is a conscious, controlled step
## Agent Assignment Guidance
For maximum parallelization:
- **Foundation Agent:** Sprints 7000-0001-0001, 7000-0001-0002
- **SDK Agent:** Sprints 7000-0003-0001, 7000-0003-0002
- **Gateway Agent:** Sprints 7000-0004-0001, 7000-0004-0002, 7000-0004-0003
- **Transport Agent:** Sprints 7000-0002-0001, 7000-0006-*
- **Protocol Agent:** Sprints 7000-0005-*
- **Config Agent:** Sprints 7000-0007-*
- **Integration Agent:** Sprints 7000-0008-*, 7000-0010-0001
- **Documentation Agent:** Sprint 7000-0009-0001
## Invariants (Never Violate)
From `specs.md`, these are non-negotiable:
- **Method + Path** is the endpoint identity
- **Strict semver** for version matching
- **Region from GatewayNodeConfig.Region** (never from headers/host)
- **No HTTP transport** between gateway and microservices
- **RequiringClaims** (not AllowedRoles) for authorization
- **Opaque body handling** (router doesn't interpret payloads)
Any change to these invariants requires updating `specs.md` first.
