1. DTO And Router Contracts

• 1.1 Add named DTO list/error response contracts and request-to-domain conversion helpers for core resource create requests.
• 1.2 Add injectable platform router construction that wires health and core API routes through service.Core with an in-memory default.

2. Core API Handlers

3. API Tests

• 3.1 Add handler tests for successful create/list/detail workflows and query filters.
• 3.2 Add handler tests for malformed JSON, validation errors, duplicates, missing resources, dependency failures, and AI provider redaction.

4. Verification

• 4.1 Run go test ./... from platform/ and record evidence.
• 4.2 Run scripts/check-structure.sh and record evidence.
• 4.3 Run openspec validate implement-platform-api-surface --strict and record evidence.
