# Channel assembly # Channel assembly Platform Composes audience, template and send capabilities into one deterministic end-to-end channel service — the internal data contracts, candidate generation, scoring, allocation, outputs and runtime validation. - **Used when** — When the separate communication capabilities need to become a single service that behaves the same way twice. - **Loads first** - The runtime-assembly skill. - The batch-workflow and solver skills, where allocation is an optimisation rather than a sort. - **Returns** - The runtime data contract and the candidate-generation plan. - The scoring, allocation and output contracts. - The validation and rollout plan. - Its integration points with the three capabilities it composes. - **Hands off** - Audience selection — the audience entry point and its intake contract - Template inventory — the template inventory - Send lifecycle — provider delivery and response ingestion ## Others in Platform - Audience selection - Batch workflows - Capability map - Contact scheduling solver - Conversation management - Conversation runtime - Mail campaign operations - Message assistant - Rule editor - Short links - Solver services - Template inventory
