Phase 6C pass 2. Every link in the module UI chain existed except the one that closes it: a module could be authored, built, validated, published at a browser URL, and loaded by a generic loader — and nothing in Ekklesia did any of it. There was no browser application at all. Two pieces were missing. A browser could not discover what to mount, and it must not work that out for itself. GET /api/v1/module-ui is the inventory: per publishable module, its id and version, the server-produced artifact URL, the server-produced root of the module's own API, and the subset of that module's declared permissions the caller holds. Five fields, each because building a ModuleUiHostContext needs it — no filesystem paths, and no name/icon/folder/order, because navigation metadata is a design that does not exist yet. Its module set is the ADR 0025 publication registry rather than a rescan, so the inventory and the artifact route cannot disagree. It requires a new Core permission, core.modules.ui.read (baseline authenticated), because it is precisely the enumeration the anonymous artifact route deliberately withholds. Both URLs are server-produced. moduleUiArtifactUrl already existed; moduleApiBaseUrl is now exported and moduleRoutePath builds on it, so each URL shape has exactly one author. Without it the shell would hardcode /api/v1/modules/<id> — the prefix ADR 0022 forbids a module UI from spelling, reappearing in the host instead. surfaces/shell (@ekklesia/shell) is the repository's first surface: a small React application built to static files by its own esbuild script. It resolves the principal, fetches the inventory, builds the host context entirely from server-derived data, and hands the artifact URL to @ekklesia/module-ui-host. One frame per selection — keyed by module identity — defeats the stale-load race; the host owns the container, the loading state, and every failure, so a broken module costs its own panel rather than the shell. The shell statically imports no module, and both levels are checked: no source import may name a module, and the emitted bundle must contain exactly one dynamic import (the loader's) with no module id, no /api/v1/modules, no eval, and no blob URL. Permission hints come from Core's own evaluator and stay presentation-only — the end-to-end test has a UI holding no grant call its API anyway and still receive 403. Surfaces may now depend only on browser-safe shared roles; @ekklesia/contracts is deliberately excluded, since its barrel pulls Drizzle's types and Node's globals into the browser — the hole ADR 0024 closed one layer down. Not the Dashboard: no navigation, grouping, icons, ordering, design system, or routing. The selector is a list of module ids. Co-Authored-By: Claude Opus 5 <[email protected]>
Architecture decision records
ADRs capture durable choices that affect more than one package or phase.
- Filenames use a four-digit sequence followed by a short kebab-case title.
- Status is
Proposed,Accepted,Superseded, orRejected. - Accepted ADRs are immutable except for status and cross-reference corrections.
- A changed decision receives a new ADR that links to and supersedes the old one.
