It runs on the shop's machine and keeps execution behind exact-payload confirmation. Approvals are immutable, single-use, and expiring; unsupported and high-risk requests fail closed.</p> <h2> Try Mosaic </h2> <p>Start with the product page for the real UI and setup path:</p> <p><a href="https://hearthplug.github.io/mosaic-erp/" rel="noopener noreferrer">https://hearthplug.github.io/mosaic-erp/</a></p> <p>Download the verified v1.3.0 release archives and checksums:</p> <p><a href="https://github.com/Hearthplug/mosaic-erp/releases/tag/v1.3.0" rel="noopener noreferrer">https://github.com/Hearthplug/mosaic-erp/releases/tag/v1.3.0</a></p> <p>Mosaic is MIT licensed.
