Inventory System: Objects With a History IMAGEInventory System: Objects With a History

PROJECT README

README

Inventory System tracks physical objects as an append-only stream of observations and lifecycle events instead of a mutable spreadsheet.

Stable QR labels reconnect each real object to its history, while projected current state powers kitchen queues, expiration guidance, quantity workflows, and audit-friendly replay. The architecture is designed to grow from household inventory into reusable workspace-specific rules without losing provenance.

ARTICLE

Why This Inventory Uses Events Instead of Overwriting Facts

A technical explanation of the event ledger, projections, replay, and idempotent interactions.

ARTICLE

A Photo Can Suggest an Item, Not Create One

Photo analysis prepares an editable draft; only reviewed facts enter the ledger.

ARTICLE

From Expiration Dates to Explainable Decisions

Storage context and human observations turn rough dates into useful action queues.
