Build a Make.com scenario from a plain-English flow

Help me build a Make (formerly Integromat) scenario.

The flow I need (plain English): {{flow}}
Trigger app + module: {{trigger}}
Action apps in order: {{actions}}
Optional: any data transformation I need (filter, mapping, aggregator): {{transformations}}
Run frequency / schedule: {{schedule}}

Return:
1. SCENARIO STRUCTURE — list each module in order. For each: app, module name (the exact one from Make's catalogue), and what it does in this flow.
2. ROUTER OR FILTER LOGIC if the flow branches.
3. KEY MAPPINGS — which output fields from each module feed into the next, named by Make's field labels.
4. ERROR HANDLING — name 1 module where I should add a route + 'Resume' / 'Break' handler.
5. FIRST-RUN TEST: a single test record I should fire through to verify, and the expected outcome.

AU English. Don't output JSON — Make doesn't accept import-from-JSON for first-time users. Step-by-step in the visual builder.
