Design record for distributing optional plugins across GE sites: a small mandatory core plus a catalog of optional plugins, packaged as signed versioned artifacts, served from a transport-agnostic read-only shelf (a SharePoint-synced or sneakernet folder - untrusted either way because every decision-bearing byte is signed), verified at adopt AND at every load and migrate. Lean per-site builds stage only chosen plugins into the backend image and SPA bundle. Status PROPOSED. Grounds the design in the real loader/contract/migration/ frontend code and records defects to fix along the way (upgrade-all migrating unadopted folders, enable-without-install, reverse-dep checks blind to unloaded plugins, missing cycle detection and dependency closure, hardcoded plugin imports in the SPA router). Honest on scope: the frontend re-org is the long pole (one core-router change plus per-plugin relocation), not a mechanical move. Phased 0-5 with schema-lean and runtime-JS delivery explicitly deferred.

Architecture Decision Records
Each ADR captures a single architectural decision: the context, the decision itself, the consequences, and the alternatives considered. ADRs are immutable once accepted. Superseded ADRs stay in this folder with a pointer to the newer ADR.
Status definitions
- PROPOSED: drafted, awaiting decision
- ACCEPTED: decision is in effect
- SUPERSEDED: replaced by a later ADR (link forward)
- DEPRECATED: no longer in effect, no replacement
