nawnie/atlas-core ? reverse-engineered prompt

Build me a local first Atlas Core app that acts like a shared memory layer for business records and explains what changed between versions.

I want a small local runtime with a simple command line demo and a browser based operator console. It should ingest example records, turn them into one canonical event model, keep track of where each piece of data came from, compare updates against the previous version, and show a clear explanation of the changes. When the system thinks an action should happen, it should create a proposal and wait for a human approval before anything is executed.

Please make the first working example the hotel workflow, with a fake local sandbox for reservations, cancellations, revenue changes, approvals, receipts, rollback, and an audit trail I can inspect. The console should also show pending, approved, rejected, and blocked items, plus import history and searchable lineage cards. Keep it fully local, deterministic, and safe by default, with preview first imports and no external services. If you need to check anything, look up current docs online.
