a025cadc44 feat(02-04): wire escalation into orchestrator pipeline 
- Add escalation pre-check in _process_message: assistant mode for escalated threads
- Add escalation post-check after LLM response: calls escalate_to_human on rule match
- Load Slack bot token unconditionally (needed for escalation DM, not just placeholders)
- Add keyword-based conversation metadata detector (billing keywords, attempt counter)
- Add no-op audit logger stub (replaced by real AuditLogger from Plan 02 when available)
- Add escalation_assignee and natural_language_escalation fields to Agent model
- Add Alembic migration 003 for new Agent columns

28a5ee996e feat(02-01): add two-layer memory system — Redis sliding window + pgvector long-term 
- ConversationEmbedding ORM model with Vector(384) column (pgvector)
- memory_short_key, escalation_status_key, pending_tool_confirm_key in redis_keys.py
- orchestrator/memory/short_term.py: RPUSH/LTRIM sliding window (get_recent_messages, append_message)

- Migration 002: conversation_embeddings table, HNSW index, RLS with FORCE, SELECT/INSERT only
- 10 unit tests (fakeredis), 6 integration tests (pgvector) — all passing
- Auto-fix [Rule 3]: postgres image updated to pgvector/pgvector:pg16 (extension required)

7b348b97e9 feat(01-04): FastAPI portal API endpoints with tenant/agent CRUD and auth 
- Add packages/shared/shared/api/portal.py with APIRouter at /api/portal
- POST /auth/verify validates bcrypt credentials against portal_users table
- POST /auth/register creates new portal users with hashed passwords
- Tenant CRUD: GET/POST /tenants, GET/PUT/DELETE /tenants/{id}
- Agent CRUD: full CRUD under /tenants/{tenant_id}/agents/{id}
- Agent endpoints set RLS current_tenant_id context for policy compliance
- Pydantic v2 schemas with slug validation (lowercase, hyphens, 2-50 chars)
- Add bcrypt>=4.0.0 dependency to konstruct-shared
- Integration tests: 38 tests covering all CRUD, validation, and isolation
