Greptile Summary

This PR adds a complete Shopware 6 blueprint with a multi-stage init chain (bootstrap → init-permissions → init → runtime services), MySQL 8.4, Redis 7.4, a background worker, and a scheduler. All repo conventions are met: version 3.8, named volumes only, expose instead of ports, and the primary service is named shopware to match the blueprint folder.

The only finding is a minor inconsistency in the init, shopware, worker, and scheduler entrypoints, which use a bare $ for shell command substitutions ($(cat ...)) while bootstrap correctly uses $$ to escape the $ from Docker Compose's variable interpolation engine. In practice this works on current Docker Compose v2, but the $$ form is the guaranteed-safe approach.

Confidence Score: 5/5

• Safe to merge — the only finding is a cosmetic $ vs $$ inconsistency that works correctly on all current Docker Compose v2 releases.
• All remaining findings are P2 style suggestions. The blueprint is functional, tested by the author, follows all repo conventions, and prior review feedback on restart policies and failed-queue documentation has been fully addressed.
• No files require special attention.
