Phase 0 Sprint 0.1 - Telemetry Capability Removal

Scope

This sprint removes telemetry ingestion from the client API and keeps the client API focused on tenant portal read and compliance access patterns.

Threat Model

• Asset: tenant telemetry data, client API attack surface, tenant isolation boundaries.
• Adversary: external actor abusing public write routes, compromised integration client, replay actor.
• Trust boundary: all public client API endpoints.

Attack Vectors Considered

• Unauthorized telemetry POST attempts to /api/v1/client/events.
• Abuse of /api/v1/integrations/spectrastrike/* ingestion endpoints.
• Replay or forged ingestion payload submissions.
• Lateral tenant probing through ingest status APIs.

Mitigations Implemented

• Removed SpectraStrike telemetry ingestion router from the runtime API.
• Removed client telemetry event ingestion endpoint from vv_client_api.py.
• Removed ingestion DTO/controller/service modules previously used by SpectraStrike ingest flows.
• Added security regression tests to enforce endpoint absence and write-method rejection on read-only resources.
• Added SQL cleanup script to drop telemetry ingestion tables:
  • spectrastrike_ingest_requests
  • spectrastrike_idempotency
  • spectrastrike_events
  • spectrastrike_findings
  • client_activity_events

Residual Risk

• Portal code may still attempt telemetry calls; these now fail closed (404).
• Existing deployed databases require explicit cleanup script execution.
• Legacy docs/manual references can reintroduce confusion if not retired consistently.

Future Improvements

• Introduce dedicated private telemetry gateway (Phase 1) with mandatory mTLS and signature verification.
• Add startup policy checks that fail service boot when public telemetry ingestion routes are present.
• Add CI policy gate that scans OpenAPI for forbidden ingestion endpoints.
