Classroom Public Adapter Preflight Task

Agent workflow: follow README.md for Audit -> Investigate -> Code -> Test -> Fix; keep this pack's writable scope and verification commands authoritative.

Dispatch type: orchestrator

Owner: classroom-service; orchestrator owns gateway route examples.

Goal:

Prepare /api/classrooms* native route promotion only after cross-service validation and hydration boundaries are explicit.

Legacy source evidence:

• /Users/velikho/Desktop/WORKING/HOCTAPAZ/node-platform/apps/api/src/modules/classrooms/**
• /Users/velikho/Desktop/WORKING/HOCTAPAZ/node-platform/apps/api/prisma/schema.prisma
• classroom frontend callers under /Users/velikho/Desktop/WORKING/HOCTAPAZ/node-platform/apps/web.

Writable files:

• services/classroom-service/**
• contracts/openapi/services/classroom-service.yaml
• docs/api/classroom-service.md
• docs/agents/service-tasks/classroom-public-adapter-preflight.md

Orchestrator-owned files:

• Gateway route tables, profile/org hydration adapters, shared deploy manifests, and default public route promotion.

Tasks:

• Audit legacy classroom list/detail/member/join flows.
• Define profile/org hydration inputs that classroom-service receives by ID or gateway aggregation.
• Add route guard coverage proving default routes stay legacy.
• Add focused tests for join code, member writes, delete impact, purge, and progress summary.

Acceptance:

• Classroom-service does not read profile, IAM, organization, document, question, or exam databases.
• Native promotion has rollback route-table evidence.

Verification:

• GOTOOLCHAIN=go1.25.11 go test ./services/classroom-service/... ./services/api-gateway/internal/gateway
• make test-classroom-route-guard
