FastAPI + SQLite behind a single-page frontend, deployed as a container on mainserver behind Caddy. One flexible parts table plus key/value specs so components, filament, fasteners and tooling share a schema. Categories and locations are nestable trees whose filters and sidebar counts both roll up through descendants. Category spec templates pre-fill the properties worth recording for each kind of part, which is what makes manual entry tolerable. Every quantity change is logged. Search is FTS5 with prefix matching across names, MPNs, spec values, tags, category and location. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

Seeded once, on an empty database. A category's template is only a suggestion —
|
|
the add form pre-fills those keys, and you can delete any of them or add your
|

own. Nothing here constrains what a part may hold.
