Direct-to-consumer brands: inventory manager using Laravel

Summary

A inventory manager blueprint for direct-to-consumer brands built with Laravel on Ample. Domain schema:

Technical Basis

Verified on Laravel: an optimistic version check and an event row written in the same transaction, a stale update rejected, and a history query over the application-owned events (history=2 conflict=rejected).

Resource Requirements

Infrastructure Requirements

  1. Compute: Apps run in isolated x86_64 Firecracker microVMs that auto-pause when idle and wake on request; sizes are the priced VM sizes.
  2. Postgres: Managed PostgreSQL 16 runs in its own microVM and is auto-provisioned when an app needs a database and no DATABASE_URL is supplied.
  3. S3-compatible object storage: Buckets are S3-compatible with issued credentials; PutObject and GetObject are verified by canary. Other S3 operations are not verified.

Workflow Steps

  1. Model the direct-to-consumer brands domain: Create the tables products, stock_movements, orders, order_lines, events. Product catalog lives in products; keep the sensitive classes (customer contact and payment details, discount codes tied to individuals) out of this schema.
  2. Workflow step 1: Model SKUs and stock movements; derive stock from movements.
  3. Workflow step 2: Apply movements transactionally with an optimistic version check on the SKU.
  4. Workflow step 3: Record an event per movement for history.
  5. Workflow step 4: Deploy and verify history and rejected stale updates.
  6. Deploy: Run the synchronous deploy once and read the result. Re-running with no change is a no-op.
  7. Verify: Run the pattern self-test(s) from the example (/p/transactional-workflows) and your own acceptance checks for the direct-to-consumer brands workflow.
