Domain schema: services (sku, name, category, price_from, duration_estimate): service catalog as SKUs; parts_stock (sku, delta, reason, moved_at): parts and consumables movements; jobs (job_no, service_area, status, scheduled_for): jobs as orders with status transitions; job_lines (job_no, sku, qty): services and parts on a job; events (seq, record_type, record_id, kind, at): application-owned history written in the same transaction. Public information: service catalog and pricing from, service areas and hours, licensing and insurance summary. Kept out of scope until handling is reviewed: customer addresses and access notes, payment details. Customer addresses and access instructions are personal data; keep them out until handling is reviewed. Technical basis verified on Django: 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).","representativeQueries":["Home services: inventory manager using Django","Where can I host Home services: Inventory manager built with Django?","I need a genuinely specialized inventory manager workflow covering service areas, job materials and field-job status."],"breadcrumbIds":["discovery","industry","industry:commerce-and-local-services","industry:home-services","page:blueprints:home-services:inventory-manager:django"],"breadcrumbs":[{"id":"discovery","label":"Agent hosting discovery","canonicalPath":"/discover/discovery","kind":"root"},{"id":"industry","label":"Industries and specialties","canonicalPath":"/discover/industry","kind":"facet"},{"id":"industry:commerce-and-local-services","label":"Commerce and local services","canonicalPath":"/discover/industry/commerce-and-local-services","kind":"group"},{"id":"industry:home-services","label":"Home services","canonicalPath":"/discover/industry/home-services","kind":"atom"},{"id":"page:blueprints:home-services:inventory-manager:django","label":"Home services: inventory manager using Django","canonicalPath":"/blueprints/home-services/inventory-manager/django","kind":"recipe"}],"parentIds":["industry:home-services","workload:inventory-manager","stack:framework-django","intent:deploy-web-app"],"parents":[{"id":"industry:home-services","label":"Home services","canonicalPath":"/discover/industry/home-services","kind":"atom"},{"id":"workload:inventory-manager","label":"Inventory manager","canonicalPath":"/discover/workload/inventory-manager","kind":"atom"},{"id":"stack:framework-django","label":"Django","canonicalPath":"/discover/stack/framework-django","kind":"atom"},{"id":"intent:deploy-web-app","label":"Deploy web app","canonicalPath":"/discover/intent/deploy-web-app","kind":"atom"}],"resourceRequirements":["primitive:compute","primitive:postgres","primitive:s3-compatible-object-storage"],"infrastructureRequirements":[{"primitiveId":"primitive:compute","label":"Compute","canonicalPath":"/discover/primitive/compute","status":"verified","summary":"Apps run in isolated x86_64 Firecracker microVMs that auto-pause when idle and wake on request; sizes are the priced VM sizes."},{"primitiveId":"primitive:postgres","label":"Postgres","canonicalPath":"/discover/primitive/postgres","status":"verified","summary":"Managed PostgreSQL 16 runs in its own microVM and is auto-provisioned when an app needs a database and no DATABASE_URL is supplied."},{"primitiveId":"primitive:s3-compatible-object-storage","label":"S3-compatible object storage","canonicalPath":"/discover/primitive/s3-compatible-object-storage","status":"verified","summary":"Buckets are S3-compatible with issued credentials; PutObject and GetObject are verified by canary.
