Modules had no way to be told anything. Announcements — the first real product Ekklesia will absorb — has zero environment variables and compiles a LAN IP address into its source, so this is the contract standing between it and the module system. - A module declares what it needs in its manifest, using six bounded types (string, integer, boolean, enum, url, secret) with no nesting and no regular expressions. Static declaration is what lets the platform validate configuration *before* deciding whether a module may start: an enabled module missing a required value is reported `blocked · configuration_missing · <key>` rather than taking startup down from inside its own `start` hook, and Doctor reports the same while still importing no module code. That forces `manifestVersion: 5`, a hard cutover. - Ordinary values persist in one Core table (migration 0005), one row per (module_id, key), stored as text until validated against the declaring module's current manifest. Nothing is coerced; an invalid stored value blocks the module rather than falling back to the default. A key the manifest no longer declares is retained and ignored. - Secrets are never persisted. There is no encryption at rest in this repository, so a `secret` key is deployment-supplied and mapped in by the host under a name the module never sees. A secret declaration has no `default` field, the write API refuses secret material, and the HTTP view has no `value` field for one — absent by construction, not filtered. - Modules receive a frozen `context.config` on the registration, runtime, and HTTP handler contexts: the same object identity, per module, beside `services` rather than inside it (services is deliberately one shared instance). No environment access, no database reference, no way to reach another module's values. - Configuration decides eligibility through ADR 0028's existing resolver: three new blocked reasons, each with a distinct operator fix, propagating to required dependents through the same mechanism as a disabled module. - Changes take effect at the next restart; both resources report restartRequired. New restricted permission `core.modules.configuration.manage`, separate from lifecycle, at the sibling prefix `/api/v1/module-configuration`. - Migration participation stays independent of configuration validity. Endpoints and credentials for shared infrastructure stay platform concerns; a module declares which bucket it needs, not an S3 endpoint. See ADR 0029.

Ekklesia module template
This is the smallest supported backend-only Ekklesia module. It proves the static manifest,
compiled runtime and schema entrypoints, capability registration, a module-owned Drizzle table, a
generated module-owned migration, logical storage-bucket declarations, and one permissioned HTTP
route (GET /records, declared in register) that reads that table through
context.services.database — the platform-provided ModuleDatabase facade, never a
module-constructed Drizzle instance or a raw pg client. Migration execution and storage
provisioning are intentionally not included.
It also ships an optional React UI (src/ui/), compiled to the entrypoints.ui artifact its
manifest declares by pnpm build
(ADR 0023). UI is a choice, not
a requirement: to keep a module backend-only, delete src/ui/, tsconfig.ui.json,
tsconfig.ui-test.json, tests/module-ui.test.ts, the ui entrypoint from the manifest, and the
React and module-UI dependencies. Everything else keeps working, and ekklesia-build-module-ui
simply reports that there is nothing to build.
No host mounts a module UI yet — the Dashboard shell does not exist. tests/module-ui.test.ts builds
the artifact from source, validates it with parseModuleUiExport, mounts it into a real DOM, and
unmounts it, which is what proves the pipeline today. See
Declaring a UI entrypoint.
To create a module inside this repository:
- Copy this directory to
modules/<module-id>. - Rename the package in
package.jsonand removeprivatewhen it is ready for publication. - Update the ID, name, version, namespaces, compatibility ranges, and bucket requests in
ekklesia.module.json. - Keep the manifest capability versions and dependency ranges aligned with the contracts the module actually implements and consumes.
- Replace
src/server/index.tswith backend behavior only. ItsdefineModuleRuntimeID and version must match the manifest; do not duplicate the rest of the manifest in TypeScript. Declare HTTP routes only inregister, against a permission the manifest already declares;start,stop, and every route handler — neverregister— receivecontext.services.database, a typedModuleDatabaseview over the platform's one PostgreSQL pool. - Replace the pure Drizzle declarations in
src/schema/tables.tsand keep its table prefix aligned with the module ID. Keep thedefineModuleSchemaownership wrapper insrc/schema/index.tsaligned too, and never import another module's schema. - Update
drizzle.config.ts, generate forward migrations withpnpm migration:generate --name=lowercase_namefrom the module directory, and review the SQL. Keep each generated tag indrizzle/meta/_ekklesia.json, classify it asnoneorapproval-required, and change that file'smoduleIdwhen renaming the template. - Run
pnpm install,pnpm build,pnpm modules:validate,pnpm migrations:validate, andpnpm verifyfrom the repository root. The declared production entrypoint is the compileddist/server/index.js, not source TypeScript; the schema entrypoint is likewise compiled todist/schema/index.js.
Do not add UI components, styles, renderers, navigation, or layouts. Those belong to surfaces.
Keep imports side-effect-free, register capabilities in register, acquire resources in start,
and release them in stop. Never construct a Drizzle instance, read DATABASE_URL, or reach for a
raw pg client — context.services.database is the only supported way to query this module's own
tables, and it is never available during register.
The migration directory uses the pinned stable Drizzle Kit 0.31.10 PostgreSQL journal and
snapshot format. Migrations are forward-only and may modify only this module's objects. Offline
validation treats SQL as opaque bytes, calculates SHA-256 from the exact contents, and never opens a
database or executes SQL. Destructive declarations are review metadata, not automatic SQL
classification or approval.
