TAPPaaS Module Dependency Model

Computed from every module's <module>.json (dependsOn: "provider:service"). Three views: the platform plumbing every module uses, the application topology worth drawing, and the complete per-module reference.

Generated: 2026-10-06 by generate-module-dependencies.sh from 26 modules / 105 dependencies — do not edit by hand.

1. Platform plumbing

These foundation services are consumed near-universally; drawing them would bury the interesting structure. A module uses them unless its entry in the reference below says otherwise.

Service Consumers (of 26 modules)
cluster:vm 18
backup:vm 17
network:proxy 16
templates:nixos 13
network:rules 12
identity:identity 7
cluster:ha 6

2. Application topology

Everything that is not plumbing — the dependencies that shape the platform. Multiple services between the same pair are merged into one labeled edge; providers marked (external) have no module in this repo yet.
