Decisions (ADRs)
Overview
ADR-0001 — Pure DI at a composition root (no DI container)
ADR-0002 — Stack state: three roles, one authority per role (the manifest model)
ADR-0003 — One data-ladder Scope type
ADR-0004 — Hermetic default test lane, engine fidelity lane
ADR-0005 — Architectural fitness functions
ADR-0006 — Thread registry.Deps through every seam; no global root pointer
Proposals
Overview
#113 quorum-safe removal v2 — reachability-aware guard + bounded RPCs + recovery hint
Symmetric node model: an shcnode for every node, shccluster becomes pure config (2026-07-15)
System-app overrides + Keycloak's own host (2026-07-15)
ACME/Let's-Encrypt issuance as first-class named providers
Canonical app.yaml metadata schema (census-driven) (2026-07-17)
ManifestAdapter interface + the coolify/umbrel/casaos adapters (2026-07-17)
Post-deploy notes templating (Helm NOTES.txt style) (2026-07-17)
Origin ingest gate + materialized transpile (2026-07-17)
Origin repos (foreign catalogs) + migrations to native apps (2026-07-17)
Resource Meta-API — self-describing resources, one contract for every client
Bundled services vs. sockets: a catalog-wide audit
Edge-CA trust: making server-side OIDC survive a non-public ACME directory
Integration-edge identity: the model
Persist the backup manifest inside the restic repo (2026-07 cross-cluster recover finding)
Daemon bind/advertise split (2026-07 mixed-cluster finding)
Retire the CLI's ROPC password grant — device-code flow as the sole interactive acquire path, client-credentials for CI
Plan: 5-level config scoping + DNS target resolver (LB override + swarm multi-A)
Cross-cloud convergence plan (2026-07-13 live campaign)
SHC Daemon DI Migration — Master Plan
Plan: deployment poll consumes recorder rows + small DNS/config knobs
Plan: hook action lists + runtime refs (full migration, no legacy)
Plan: real per-container status during shc install (install-time live service tracking)
Integration teardown: wake the 28 dead jobs, then collapse three runners into one
Live host reconfig — changing the cluster host without re-genesis
Cluster-CA succession — dual-trust rollover for the node-mTLS root
Short-lived :4003 node leaves + renewal as the passive revocation backstop
Vault envelope encryption: replace per-row PBKDF2 with a cached KEK + per-row DEK
