Lists canonical service placement and stack membership, with reasons and inventory freshness and completeness. An empty services array means no affected services only when inventory.status is current. An incomplete, stale or unavailable inventory cannot authorize maintenance. The digest binds the server, operation and material dependency snapshot; ordinary observation timestamps do not invalidate unchanged impact. Responses are private and must not be cached. ## OpenAPI ````yaml /techstack/reference/api/openapi.yaml get /api/v1/servers/{serverId}/maintenance-impact openapi: 3.1.0 info: title: kombify-TechStack API description: > REST API for kombify-TechStack -- the hybrid cloud control plane for homelabs. kombify-TechStack manages infrastructure through a spec-driven architecture: validate YAML specs via CUE, generate OpenTofu configurations, and manage nodes through a gRPC agent protocol. ## Authentication Authenticated endpoints accept an OIDC/JWKS bearer token or an API key where documented. Self-hosted TechStack defaults to Pocket ID as identity provider. SaaS routes enter through the edge with Auth0 as the platform identity provider. PocketBase session exchange remains legacy migration compatibility only. ## Response Format **Success:** `{ "data": , "meta": { "total": int, "page": int, "per_page": int } }` **Error:** `{ "error": { "code": "", "message": "...", "details": } }` ## Pagination List endpoints accept `page` (default: 1) and `per_page` (default: 20, max: 100) query parameters. version: 1.0.0 contact: name: kombify url: https://kombify.io license: name: Apache-2.0 AND GPL-3.0 url: https://github.com/KombiverseLabs/kombify-TechStack/blob/main/LICENSE servers: - url: https://api.kombify.io/v1/techstack description: >- Production canonical (via Cloudflare edge gateway, strip-prefix).
