RED phase — tests are written, will pass when connected to live DB.
Tests cover:
- Full RBAC matrix: platform_admin/customer_admin/operator on all endpoints
- Operator can POST /test but not POST /agents (create)
- Missing headers return 422
- Impersonation creates AuditEvent row
- Full invite flow: create -> accept -> login with correct role
- Expired invite rejection
- Resend generates new token and extends expiry
- Double-accept prevention
- Create llm_keys.py: GET list (redacted, key_hint only), POST (encrypt + store), DELETE (204 or 404)
- LlmKeyResponse never exposes encrypted_key or raw api_key
- 409 returned on duplicate (tenant_id, provider) key
- Cross-tenant deletion prevented by tenant_id verification in DELETE query
- Update api/__init__.py to export llm_keys_router
- All 5 LLM key CRUD tests passing (32 total unit tests green)
- Add stripe and cryptography to shared pyproject.toml
- Add recharts, @stripe/stripe-js, stripe to portal package.json (submodule)

- Move key imports to module level in tasks.py for testability and clarity
- Pop WhatsApp extras (phone_number_id, bot_token) in handle_message before model_validate
- Build unified extras dict and extract wa_id from sender.user_id
- Change _process_message signature to accept extras dict
- Add _build_response_extras() helper for channel-aware extras assembly
- Replace all _update_slack_placeholder calls in _process_message with _send_response()
- Add escalation pre-check: skip LLM when Redis escalation_status_key == 'escalated'
- Add escalation post-check: check_escalation_rules after run_agent; call escalate_to_human
when rule matches and agent.escalation_assignee is set
- Add _build_conversation_metadata() helper (billing keyword v1 detection)
- Add channel parameter to build_system_prompt(), build_messages_with_memory(),
build_messages_with_media() for WhatsApp tier-2 business-function scoping
- WhatsApp scoping appends 'You only handle: {topics}' when tool_assignments non-empty
- Pass msg.channel to build_messages_with_memory() in _process_message
- All 26 new tests pass; all existing escalation/WhatsApp tests pass (no regressions)
- Add supports_vision(model_name) to builder.py — detects vision-capable models
(claude-3*, gpt-4o*, gpt-4-vision*, gemini-pro-vision*, gemini-1.5*, gemini-2*)
with provider prefix stripping support
- Add generate_presigned_url(storage_key, expiry=3600) to builder.py — generates
1-hour MinIO presigned URLs via boto3 S3 client
- Add build_messages_with_media() to builder.py — extends build_messages_with_memory()
with media injection: IMAGE -> image_url blocks for vision models / text fallback for
non-vision models, DOCUMENT -> text reference with presigned URL
- image_url blocks use 'detail: auto' per OpenAI/LiteLLM multipart format
- Add 27 unit tests in test_multimodal_messages.py (TDD)
- Tests for BUILTIN_TOOLS (4 tools present, correct fields, confirmation flags)
- Tests for get_tools_for_agent filtering and to_litellm_format conversion
