Core Concepts

The ideas that shape the etg24 platform. They apply to REST and MCP alike — grouped here exactly like the page tree on the left.

Platform

• CQRS — commands change state, queries read data
• Full API coverage — everything the app can do is reachable via API
• Intelligent & semantic search — search by meaning, over REST and MCP
• Performance & scale — built for high-volume workloads
• Webhooks — events for objects, units and contacts

Trust & Safety

• Per-agent attribution — every agent is its own actor in the log
• Soft delete — deletes are reversible almost everywhere
• Change attribution — every change records who did it and when
• Rollback — what to do when an agent gets it wrong

Identity & Access

• Identity & delegation — every integration actor is a named agent
• Permission scopes — read-only by choice, write scoped to capabilities
• Key lifecycle — see, disable and replace keys

Data Formats

• HTML content — the sanitization allowlist
• Document types — the machine-readable type mapping
