- Implemented `run-scanner-ci.sh` to build and run tests for the Scanner solution with a warmed NuGet cache. - Created `excititor-vex-traces.json` dashboard for monitoring Excititor VEX observations. - Added Docker Compose configuration for the OTLP span sink in `docker-compose.spansink.yml`. - Configured OpenTelemetry collector in `otel-spansink.yaml` to receive and process traces. - Developed `run-spansink.sh` script to run the OTLP span sink for Excititor traces. - Introduced `FileSystemRiskBundleObjectStore` for storing risk bundle artifacts in the filesystem. - Built `RiskBundleBuilder` for creating risk bundles with associated metadata and providers. - Established `RiskBundleJob` to execute the risk bundle creation and storage process. - Defined models for risk bundle inputs, entries, and manifests in `RiskBundleModels.cs`. - Implemented signing functionality for risk bundle manifests with `HmacRiskBundleManifestSigner`. - Created unit tests for `RiskBundleBuilder`, `RiskBundleJob`, and signing functionality to ensure correctness. - Added filesystem artifact reader tests to validate manifest parsing and artifact listing. - Included test manifests for egress scenarios in the task runner tests. - Developed timeline query service tests to verify tenant and event ID handling.

Platform architecture (summary)
This module aggregates cross-cutting contracts and guardrails that every StellaOps service must follow.
Anchors
- High-level system view:
../../07_HIGH_LEVEL_ARCHITECTURE.md - Platform overview:
architecture-overview.md - Aggregation-Only Contract:
../ingestion/aggregation-only-contract.md(referenced across ingestion/observability docs)
Scope
- Identity & tenancy: Authority-issued OpToks, tenant scoping, RBAC, short TTLs; see Authority module docs.
- AOC & provenance: services ingest evidence without mutating/merging; provenance preserved; determinism required.
- Offline posture: Offline Kit parity, sealed-mode defaults, deterministic bundles.
- Observability baseline: metrics/logging/tracing patterns reused across modules; collectors documented under Telemetry module.
- Determinism: stable ordering, UTC timestamps, content-addressed artifacts, reproducible exports.
Coordination
Platform docs are the starting point for new contributors; keep this summary in sync with module-specific dossiers and sprint references.
