 ## What this repository is

-Ekklesia is a modular, self-hosted church platform built as a strictly layered pnpm/TypeScript
-monorepo:
+Ekklesia is a modular, self-hosted church platform. **This repository is the platform** — Core, the
+API, the Dashboard and display shell, and the public `@ekklesia/*` module-development packages — built
+as a strictly layered pnpm/TypeScript monorepo:

 - **Core** (`core/`) owns platform infrastructure: identity, database connectivity, migration
-  execution, module discovery/lifecycle, and other feature-agnostic services. Core never imports a
-  feature module, a surface, or an app.
- **Modules** (`modules/*`, template at `templates/module`) are independently versioned product
-  packages. They own their own data and migrations, declare capabilities/permissions through
-  `@ekklesia/contracts` and `@ekklesia/module-sdk`, and must never import Core, another module, or a
-  surface directly. Per ADR 0021 a module owns its UI; manifest v7 permits independently optional
-  primary and full-viewport display artifacts, authored in React against the same role-neutral
-  `@ekklesia/module-ui-sdk` ABI. Ekklesia mounts each through a separate surface role, while
-  `pnpm boundaries` still rejects every non-React UI framework and non-`.tsx` presentation source.
+  execution, module discovery/lifecycle, devices, and other feature-agnostic services. Core never
+  imports a feature module, a surface, or an app.
+- **Modules** are independently versioned product packages. First-party modules live in **their own
+  repositories** (Signage is `Zayin/Signage`), build against the published `@ekklesia/*` packages
+  (ADR 0053), and reach an installation as a Module Package (ADR 0049) installed into module storage
+  outside the image (ADR 0048). No module source lives in this repository; `templates/module` is the
+  example, and `modules/` is only an optional, ignored local installed-modules directory. A module owns
+  its data, migrations, and **its own domain UI** (ADR 0021), declares capabilities/permissions through
+  `@ekklesia/contracts` and `@ekklesia/module-sdk`, and never imports Core, another module, or a
+  surface. Manifest v8 permits independently optional primary and full-viewport display artifacts,
+  authored in React against the role-neutral `@ekklesia/module-ui-sdk` ABI; database access is the
+  Module Database ABI v1 (ADR 0050).
 - **Surfaces** (`surfaces/*`) own the containing application shell, navigation, and every
-  presentation concern a module does not. They consume public API/client contracts only, never Core
-  or module internals directly.
+  presentation concern a module does not. The shell **hosts** module UI through the generic loader;
+  it never rebuilds a module's domain screens. Surfaces consume public API/client contracts only.

 These boundaries are enforced by `pnpm boundaries` (`scripts/check-boundaries.ts`), not just
 documented. Read `docs/architecture/repository-boundaries.md` and
 `docs/architecture/platform-architecture.md` before proposing any change that crosses a layer.

+## Product direction lives beside this repository
+
+The current roadmap and product/interface design contract are `ROADMAP.md` and `DESIGN.md` in the
+parent development directory (`../ROADMAP.md` and `../DESIGN.md` from a checkout in the standard
+`~/development/ekklesia/` layout). They are deliberately **not** committed here; do not copy them into
+this repository to make them available. They are authoritative for product direction: read the
+relevant stages and sections before designing a change. If this repository's documentation disagrees
+with them, flag the conflict, correct the repository-local documentation where appropriate, and never
+silently follow the stale text. Architectural decisions still change only through ADRs (below).
+
+Rules from those documents that every change here must respect:
+
+- **Ownership.** Modules own their domain data, behaviour, and UI. Shared resources — displays and
+  devices, accounts and identity, roles and authorization, branding, mail, push, storage providers,
+  and module installation/lifecycle — belong to the platform, and modules consume them.
+- **Branding.** Normal user-facing UI never hard-codes "Ekklesia"; product identity comes from
+  installation branding (ADR 0046). Package names, diagnostics, logs, and developer tooling may.
+  Existing hard-coded shell strings are known debt for Stage 1, not a pattern to copy.
+- **Visual direction.** Simple, minimal, and calm; responsive for phone, tablet, and desktop; light,
+  dark, and system modes. Normal UI colours come only from the shared design tokens
+  (`@ekklesia/design-tokens`, ADR 0039) — never a hard-coded colour.
+- **No browser-native dialogs.** `window.alert`, `window.confirm`, and `window.prompt` are prohibited
+  in product UI. Destructive actions use in-product confirmation proportional to their impact.
+- **Displays are transitional.** Displays are platform-owned. Today's device pairing (the Dashboard
+  sidebar's *Display devices* panel) and Signage's own display roster are a transitional
+  implementation that Stage 1 migrates to **Settings → Displays**. Fix defects in them, but do not
+  build the Stage 1 Settings, global Displays, theme editor, module installer, or responsive shell
+  redesign early, and keep existing paired displays working across any change.

 ## Working conventions

- Work on a clean branch off an up-to-date `main`; never commit or push directly to `main`; never
-  change branch-protection settings.
+- The canonical repositories are on the church Gitea under the `Zayin` organization:
+  `ssh://[email protected]:2222/Zayin/Ekklesia.git` (this one), `Zayin/Signage.git`, and
+  `Zayin/Classroom_Desktop.git`. A local clone may be behind the server: `git fetch --prune --tags`
+  and branch from `origin/main`, never from whatever is checked out.
+- One branch per PR, off an up-to-date `origin/main`. Never commit or push directly to `main`, never
+  merge your own PR, and never change branch-protection settings.
+- Never create or push a release tag. Release tags belong to the human maintainer.
+- A change that needs both a platform contract change and a module change is two PRs: Core first, on
+  its own branch, with the compatibility boundary stated explicitly; then the module. Do not copy
+  platform logic into a module to avoid making the correct Core change.
 - Keep PRs focused on one bounded slice. Record major architectural changes in an ADR rather than
  burying them in an implementation.
 - Add or update tests when you change a contract or architectural rule. New behavior needs new

+- `linux-x64-glibc`, for modules with a native dependency such as `sharp`. Its native runtime
+  packages are carried as real files under the package's `node_modules`, and the verifier checks the
+  host before anything is loaded.
+
+Every package records the module's validated SPDX expression and carries its explicitly
+supplied `LICENSE` bytes; dependency material remains separate in `THIRD_PARTY_NOTICES`. ABI-v1
+packages may bundle a module-owned Drizzle version without coupling it to Core;
+legacy-v8 packages retain their transitional exact-version check. Where a redistributed dependency
+omits licence material, the packager may add reviewed licence supplements
+([ADR 0052](docs/architecture/decisions/0052-reviewed-license-supplements.md)). A native package that
+redistributes LGPL or MPL code is distributed publicly only with its corresponding-source artifact,
+which `ekklesia-corresponding-source` builds and gates
+([ADR 0055](docs/architecture/decisions/0055-corresponding-source-artifacts.md)). Purge, other
+operating-system or CPU targets, signing, and any installer or marketplace do not exist yet.
+
+A module can be built in its own repository from Ekklesia's public module-development packages
+([ADR 0053](docs/architecture/decisions/0053-standalone-module-development-packages.md)):
+a curated `@ekklesia/module-sdk`, `@ekklesia/module-database`, the UI packages, and the build and
+packaging tools. They are released as one coordinated train of tarballs with a release manifest,
+and CI proves on every run that two builds of a commit are byte-identical and that a module outside
+the repository installs, builds, packages, and verifies from those artifacts alone. A manual
+workflow, the only way to publish, publishes exactly those artifacts to the npm registry and
+verifies every package byte for byte. Anyone may read and install the packages before launch
+([ADR 0054](docs/architecture/decisions/0054-public-package-reads-before-launch.md)). The first train
+published will be the next platform release
+([Releases and the public package train](docs/development/releases.md)).

+ * transforms and evaluates that whole graph on demand, and that work is CPU-bound. An ordinary test

+ * once and the CPU is saturated. Reproduced locally (six cores, Core's suite alongside five other
+ * packages' suites), the same tests took 3.0–5.4 s, and so timed out intermittently.
+ *
+ * 30 seconds is about five times the slowest time measured under load, which leaves room for slower
+ * shared CI runners. It matches the repository's integration-test timeout. It is still bounded, so a

+# Setting up a display kiosk
+
+A display is a screen — a television with a small computer, or a mini PC on a wall — that opens one
+module's display page full screen and keeps it open unattended. This guide sets one up so it starts
+on boot, stays paired, recovers from network and server outages on its own, and never opens a second
+copy of itself.
+
+Pairing and display identity belong to the platform (ADR 0036). Today an administrator approves a
+screen in the Dashboard sidebar's **Display devices** panel; a later release moves this to
+**Settings → Displays**. Nothing below changes when that happens.
+
+## What the screen needs
+
+- Chromium or Google Chrome, current stable. The display page is tested against Chromium.
+- A **dedicated, persistent browser profile directory**. The device credential is an HttpOnly cookie
+  in that profile; it is what keeps the screen paired across reboots. Never use a guest, incognito, or
+  "clear data on exit" profile, and never share the profile with a person's browsing.
+- Network access to the installation's **API hostname** (the display page, its realtime stream, and
+  its module requests) and to the storage hostname that serves images.
+- A clock that is roughly right. Playback follows the server's clock, but TLS does not tolerate a
+  wildly wrong one.
+
+## The address
+
+Every display-capable module has one display page on the API hostname:
+
+```text
+https://<api-hostname>/display/<module-id>
+```
+
+For Signage that is `https://<api-hostname>/display/signage`. The Signage **Displays** tab shows the
+exact address under **Copy setup address**. Open it on the screen itself; opening it on an
+administrator's own computer only previews the display (and that browser appears in the roster as a
+*Signed-in browser*, which can be removed once it is offline).
+
+## Launching the browser
+
+Run exactly **one** launcher, and launch the page as an app window with a fixed profile:
+
+```bash
+chromium \
+  --user-data-dir=/var/lib/display-kiosk/profile \
+  --app=https://<api-hostname>/display/signage \
+  --kiosk \
+  --no-first-run \
+  --noerrdialogs \
+  --disable-session-crashed-bubble \
+  --hide-crash-restore-bubble \
+  --disable-features=Translate \
+  --autoplay-policy=no-user-gesture-required \
+  --check-for-update-interval=31536000
+```
+
+- `--app` opens the page with no tab strip and no address bar. `--kiosk` makes it full screen.
+- `--user-data-dir` is the persistent profile that holds the pairing. Keep it on persistent storage
+  and back it up with nothing: if it is lost, the screen simply shows a new pairing code.
+- Do **not** add `--restore-last-session`, and do not also start the browser from a desktop autostart
+  entry. Chromium allows one process per profile; a second launch hands its URL to the running
+  process, which opens a **second window or tab** of the display. That is the usual cause of
+  "duplicate" displays. One launcher, one profile, one window.
+
+### Start on boot and restart on exit (systemd)
+
+Run the browser as an unprivileged user in that user's graphical session, from a single user unit:
+
+```ini
+# ~/.config/systemd/user/display-kiosk.service
+[Unit]
+Description=Display kiosk
+After=graphical-session.target network-online.target
+Wants=network-online.target
+PartOf=graphical-session.target
+
+[Service]
+ExecStart=/usr/bin/chromium --user-data-dir=%h/.local/share/display-kiosk --app=https://<api-hostname>/display/signage --kiosk --no-first-run --noerrdialogs --disable-session-crashed-bubble --hide-crash-restore-bubble --disable-features=Translate --autoplay-policy=no-user-gesture-required --check-for-update-interval=31536000

+
+```bash
+systemctl --user daemon-reload
+systemctl --user enable --now display-kiosk.service
+loginctl enable-linger <kiosk-user>   # with the desktop set to log this user in automatically
+```
+
+`systemctl --user stop display-kiosk` closes the browser cleanly, which is what keeps its profile —
+and the pairing cookie — intact. Avoid cutting power to a running kiosk when you can: a clean shutdown
+is always safer for a browser profile.
+
+## Pairing
+
+1. Start the kiosk. With no credential it shows a **six-digit pairing code**.
+2. In the Dashboard, enter the code under **Display devices**, give the screen a name, and approve.
+3. Within a few seconds the screen collects its credential and starts showing content.
+4. In Signage → **Displays**, name the display and choose its group and audience.
+
+A paired screen stays paired across browser restarts and reboots, and for as long as it is in use:
+its credential is renewed each time it checks in, and only expires after **180 days without being
+used** (ADR 0056). A screen that is switched off and stored for longer than that, or that is revoked,
+returns to its pairing code and is paired again the same way.
+
+## What happens when things go wrong
+
+| Event | What the screen does |
+| --- | --- |
+| Network drops for seconds | Nothing visible. The display keeps running; the realtime stream reconnects. |
+| Network or API down for longer | Keeps playing what it has cached, with a small corner note; recovers by itself when the server is back. No remount, no reload. |
+| API restarted or upgraded | Reconnects by itself. A new module version is picked up within five minutes and swapped in. |
+| Browser crashes or is restarted | systemd restarts it; the same profile is still paired. |
+| Machine reboots | Starts on boot and resumes. If the server is not up yet, the screen retries on its own (every few seconds, backing off to once a minute) until it is. |
+| Display revoked in the Dashboard | Stops showing content within seconds and returns to its pairing code. |
+| Display moved to another group or audience | Switches content within about one heartbeat (≈12 s), no reload. |
+
+**Offline cold start is not supported yet.** A screen that is already showing content survives an
+outage. A screen that *boots* while the server is completely unreachable can load its cached page but
+cannot mount the module until the server answers, because the authorization it needs is never cached
+(ADR 0043, Signage ADR 0006). It shows a short message and retries on its own until the server is
+reachable — nobody needs to touch it.
+
+## Checklist for a new kiosk
+
+- [ ] One systemd unit, no desktop autostart entry, no second launcher.
+- [ ] `--user-data-dir` on persistent storage, not shared, not cleared on exit.
+- [ ] Automatic login of the kiosk user, and screen blanking/power saving disabled.

+# 0051: Module packages declare their own license and carry its text
+
+- Status: Accepted
+- Date: 2026-10-07
+- Amends: [0049](0049-module-package-v1.md) — every Module Package v1 artifact gains an
+  authoritative package-level license declaration and a `LICENSE` payload. `packageFormat` stays 1.
+- Related: [the repository license](../../../README.md#license),
+  [ADR 0048](0048-generic-image-and-installed-module-storage.md),
+  [ADR 0050](0050-module-database-abi-v1.md)
+
+## Context
+
+ADR 0049 makes a module release one immutable, self-contained package and already requires
+`THIRD_PARTY_NOTICES` for code bundled from third-party dependencies. It deliberately says that no
+package is a distributable release until license and notice collection is proven. The implemented
+packager now generates those notices from the dependency code it actually bundles, but Module
+Package v1 still does not declare the module's own license or carry the module's license text.
+
+Those are different obligations. `THIRD_PARTY_NOTICES` excludes both the module itself and bundled
+Ekklesia-owned packages. The source module's development `package.json` is not copied into the
+package: the packager generates a minimal runtime `package.json` instead. Consequently, an archive
+can preserve every third-party notice and still lose the authoritative declaration and text for the
+work being distributed.
+
+The repository and its workspace packages declare `AGPL-3.0-or-later`, and the repository carries
+the GNU AGPL version 3 text in `LICENSE`. The canonical module template also declares
+`AGPL-3.0-or-later` in its source `package.json`. Official Ekklesia modules use that license today,
+but a packager cannot assume that every module has the platform's license. A module release must say
+what license its own publisher actually declared and must carry the corresponding material.
+
+The current `ekklesia.package.json` contract is strict: a reader refuses unknown fields. Adding a
+required field therefore makes pre-change and post-change readers reject one another's artifacts.
+That is intentional here, not a reason for `packageFormat: 2`. ADR 0049 has not admitted a
+distributable v1 release without proven license handling; this decision completes that still-open v1
+requirement before real modules are distributed. The packager and verifier must adopt the tightening
+together, and strict readers fail closed during that cutover rather than silently misreading a
+package.
+
+## Decision
+
+### The package declares the module's own license once
+
+Every Module Package v1 `ekklesia.package.json` has a required top-level `license` field containing
+the module's SPDX license expression:
+
+```json
+{
+  "packageFormat": 1,
+  "module": { "id": "example", "version": "0.1.0" },
+  "license": "AGPL-3.0-or-later"
+}
+```
+
+`ekklesia.package.json.license` is the authoritative package-release declaration. The expression is
+not repeated in `ekklesia.module.json` or in the generated runtime `package.json`. The module's
+source `package.json` is a packaging input, not release metadata inside the finished artifact.
+
+The source module must explicitly declare its license in its own project metadata. The canonical
+packager reads the normal string `license` field from the source module's `package.json`, validates
+it as a supported SPDX license expression, and preserves that declaration in
+`ekklesia.package.json`. It refuses a missing, empty, `UNLICENSED`, legacy object-shaped, malformed,
+or unsupported declaration. It never substitutes the Ekklesia platform's license and does not try
+to decide whether a publisher chose an appropriate license.
+
+For official Ekklesia modules today the declaration is `AGPL-3.0-or-later`, matching the repository
+license. This is a fact about those modules, not a default the packager invents for other modules.
+
+### The package carries the applicable license material
+
+Every distributable Module Package v1 contains a regular file at this canonical path inside the
+module directory:
+
+```text
+LICENSE
+```
+
+`LICENSE` contains the license material applicable to the module release. It is an ordinary payload
+file under ADR 0049:
+
+- it appears exactly once in the strict `files` list in `ekklesia.package.json`;
+- its byte size and SHA-256 are recorded there;
+- the archive SHA-256 covers it and the metadata that records it;
+- it is immutable for that release and changes only by producing a different archive.
+
+The license bytes must be available as an explicit source or build input. The canonical source is a
+module-owned `LICENSE` file at the module source root. Tooling may also accept an explicitly named
+license-text input when a workspace layout needs one, but it must place those bytes at the package's
+canonical `LICENSE` path. It must not search ancestor directories and silently adopt a repository
+license, generate project-specific license material, or download text from the network. The
+in-repository template implementation may later add its own `LICENSE` input or explicitly select
+the repository's AGPL text; this ADR does neither.
+
+The packager validates that both inputs exist: the declared SPDX expression and the applicable
+license text. It preserves the supplied text as deterministic package input. It is not a license
+compatibility engine and does not offer legal advice.
+
+### `THIRD_PARTY_NOTICES` remains a separate concern
+
+`THIRD_PARTY_NOTICES` continues to describe third-party packages actually bundled into or included
+with the module: their identities, versions, declared licenses, uses, and required license and notice
+texts. It is not the module's own license file and cannot satisfy the `LICENSE` requirement.
+
+The module itself is not added to `THIRD_PARTY_NOTICES`. A first-party module is not duplicated there
+merely because it uses the same AGPL license as Ekklesia. `LICENSE` and `THIRD_PARTY_NOTICES` both
+remain required because they describe different parts of the release.
+
+### Bundled Ekklesia code
+
+A module package may bundle Ekklesia-owned SDK, contracts, database adapter, UI, and related code.
+`incorporates` continues to record the exact versions of those Ekklesia components. It is an
+inventory and compatibility fact, not a second authoritative declaration of the module's license.
+
+Today's official module packages and the Ekklesia components they incorporate are all
+`AGPL-3.0-or-later`. Their package `LICENSE` therefore carries the applicable AGPL text once. The
+package does not need one identical copy per incorporated Ekklesia component, and those components
+do not move into `THIRD_PARTY_NOTICES` merely to obtain duplicate text.
+
+This ADR does not decide every future combination of a community module's license with differently
+licensed incorporated code. Publishers remain responsible for their choices and obligations. The
+packager preserves declared information and required material; it does not judge broad license
+compatibility.
+
+### Packaging and verification fail closed
+
+The implementation that follows this ADR must make the packager refuse a module when:
+
+- its source project has no acceptable explicit SPDX license expression;
+- its license-text input is missing or is not a regular file;
+- producing the package would omit `LICENSE` from the strict payload.
+
+The package verifier must refuse an artifact when:
+
+- `ekklesia.package.json.license` is missing, malformed, or outside the expression syntax the
+  contract supports;
+- the `LICENSE` payload is missing;
+- `LICENSE` is absent from the exact `files` list; or
+- its listed size or SHA-256 does not match its bytes, as with every other payload file.
+
+This ADR does not implement those checks. The contracts, packager, verifier, fixtures, template,
+and package proofs must change together in the implementation PR.
+
+### Determinism and runtime metadata
+
+`LICENSE` introduces no timestamp, generated host path, network lookup, or other environmental
+input. The deterministic archive rules in ADR 0049 apply to it unchanged.
+
+The generated runtime `package.json` remains minimal and is not authoritative for licensing. There
+is no runtime need to add a `license` field there. `ekklesia.package.json` is the release metadata,
+while the source module's `package.json` only supplies the publisher's declaration to the packager.
+
+### Package format remains 1
+
+`packageFormat` remains **1**. This is an additive tightening that completes ADR 0049's licensing
+requirement before the first distributable Module Package v1 release. It does not change the archive
+encoding, safety rules, target model, installation layout, or meaning of any existing field.
+
+The strict metadata schema is preserved. A verifier that predates this decision refuses the new
+unknown `license` field; an updated verifier refuses an old package that lacks it or lacks `LICENSE`.
+Both outcomes are safe. There is no installed or published v1 release compatibility promise to
+preserve because ADR 0049 explicitly withheld distributable-release status pending this work.
+
+ADR 0050's database ABI decision is unaffected. Whether a package uses database ABI v1 or the legacy
+database facade has no bearing on its license declaration or payload.
+
+## Consequences
+
+- A Module Package v1 release is self-describing about the module's own license and carries the
+  corresponding material without consulting its source repository or the network.
+- Operators can audit the release declaration in `ekklesia.package.json`, the module's license in
+  `LICENSE`, and dependency obligations in `THIRD_PARTY_NOTICES` without conflating them.
+- Module publishers must make both the SPDX declaration and license text explicit packaging inputs.
+- The template and every package fixture must be updated before packaging succeeds, but only in the
+  later implementation PR.
+- Existing development artifacts produced before this tightening are intentionally rejected and
+  rebuilt; none was a distributable v1 release under ADR 0049.
+- Identical AGPL text is carried once for today's official module and incorporated Ekklesia code.
+
+## Alternatives
+
+- **Use only `THIRD_PARTY_NOTICES`.** Rejected: it describes third-party dependencies and explicitly
+  excludes the module itself and Ekklesia-owned incorporated packages.
+- **Make the generated runtime `package.json` authoritative.** Rejected: it is deliberately minimal
+  runtime discovery metadata, and copying the declaration there would duplicate release metadata.
+- **Copy the platform's license automatically.** Rejected: the platform cannot declare a module's
+  license for its publisher, and a community module may make a different declaration.
+- **Search parent directories for `LICENSE`.** Rejected: the chosen file would depend on checkout
+  layout and could silently apply an unrelated repository's terms. An out-of-tree input must be
+  explicit.
+- **Download standard license text while packaging.** Rejected: builds must remain offline,
+  deterministic, and independent of a mutable remote source.
+- **Duplicate the AGPL text for every incorporated Ekklesia package.** Rejected: identical copies
+  add no information. `incorporates` records component identity and version; one applicable text is
+  sufficient for today's official packages.
+- **Create `packageFormat: 2`.** Rejected: v1 has not crossed its own distributable-release boundary,
+  strict readers fail safely, and no archive or installation mechanism changes.
+- **Make the packager decide license compatibility.** Rejected: preserving declarations and material
+  is mechanical; judging every present and future license combination is a broader legal and policy
+  problem.
+
+## Deferred
+
+- Implementing contract, packager, verifier, fixture, template, and package-proof changes.
+- The exact set and version of SPDX expression syntax accepted by the implementation, beyond the
+  requirement that unsupported expressions fail closed.
+- Broad policy for future mixed-license community modules and incorporated code.
+- Container-image license distribution.
+- Marketplace, installer, publisher verification, and package-signing policy.

+- Extends: [0049](0049-module-package-v1.md), in one respect only. ADR 0049 left exactly how licence
+  and notice material is collected to the packager's implementation. That implementation, and the
+  module development guide, then took material only from a redistributed package's own files, or

+  [ADR 0055](0055-corresponding-source-artifacts.md) (decides the source-obligation policy deferred
+  below)
+
+## Context
+
+ADR 0049 requires every Module Package v1 to carry `THIRD_PARTY_NOTICES`: the licence and notice
+material that redistributing its third-party code requires. It also states that no package is a
+distributable release until licence and notice collection is proven. The canonical packager collects
+material from two places:
+
+- the licence, copying, copyright, and notice files a redistributed package ships at its root;
+- the standard text of the package's declared licence, but only when that text is complete without
+  project-specific lines (Apache-2.0 today).
+
+A package that has neither stops packaging. That is fail-closed by design: an MIT or BSD package
+without its file is refused, because its copyright line exists only in that file.
+
+The first native-target module package needs a dependency that this rule cannot handle.
+`@img/[email protected]` is the prebuilt libvips that `sharp` loads on Linux x64 with
+glibc. It declares `LGPL-3.0-or-later`. The package itself, like its latest release 1.3.4, contains
+only these files:
+- `README.md`
+- `versions.json`
+- `lib/index.js`
+- one glib header
+- one shared library
+
+That shared library includes about 29 libraries. Its README names each one and the licence it is
+used under, mostly with a link:
+- LGPL components, such as libvips, glib, and pango;
+- cairo, under MPL-2.0;
+- many BSD-, MIT-, zlib-, IJG-, and FreeType-licensed libraries.
+
+The package ships no licence text and no copyright notice for any of them. No standard text can stand
+in for that material: it includes per-project copyright notices and several different licences.
+
+Options that were ruled out before this decision:
+- **Downloading material while packaging.** Packaging must stay offline and deterministic (ADR 0049,
+  ADR 0051).
+- **Inventing material.** A packager that guesses notices produces artifacts that look compliant and
+  may not be.
+
+Ekklesia needs a way to carry material that a dependency's own package omits. It has to be reviewed
+by people, tied to exactly the bytes it was reviewed for, and fail closed whenever that tie breaks.
+
+Some of these licences may also impose obligations beyond carrying text: the LGPL and the MPL can
+require recipients to be able to obtain corresponding source. Whether and how such an obligation is
+met for a particular redistributed binary is a legal and compliance determination. This decision
+does not make that determination.
+
+## Decision
+
+### Package-provided material stays the preferred source
+
+The licence, copying, copyright, and notice material that a redistributed package ships remains the
+primary source, collected exactly as it is today. Nothing in this ADR removes, replaces, or rewrites
+package-provided material. A supplement only adds to it.
+
+### A reviewed supplement fills what a package omits
+
+When a redistributed dependency omits material that redistribution requires, the canonical Ekklesia
+packager may use a **license supplement**: a checked-in, reviewed record of that material for one
+exact dependency.
+
+- **Where supplements live.** In the Ekklesia repository, as part of the canonical packager's own
+  versioned inputs. A supplement enters only through Ekklesia's normal reviewed change process, and
+  the change that adds it is its review. A given packager version therefore always carries the same
+  supplements.
+- **What that review is.** Repository review of a supplement is project and code review of a build
+  input: whether its content, its exact match, and its provenance are what the change says they are.
+  It is not legal review, and it does not prove that any redistribution obligation is satisfied.
+- **What a supplement may contain:**
+  - licence texts;
+  - copyright and attribution notices;
+  - provenance: where each piece of material was obtained, and which upstream component versions it
+    covers;
+  - corresponding-source information, such as where upstream source for the exact build is
+    published;
+  - other material that accompanies the dependency's redistribution.
+- **Generic by construction.** Supplements are data. The mechanism contains no package-specific code
+  and treats every supplement identically, whether it is for libvips or for any other dependency.
+
+### A supplement matches one exact package, or it fails closed
+
+A supplement names exactly one redistributed package:
+
+- its package name;
+- its exact version;
+- an integrity value for the package's contents: a digest the packager computes from the package's
+  redistributed files.
+  - **Deterministic.** It covers exactly each redistributed file's normalized relative path within
+    the package and its bytes, combined in an order defined by the paths themselves.
+  - **Host-independent.** It excludes filesystem metadata, timestamps, ownership, permissions, and
+    the order in which files were extracted or listed. The same package contents always give the
+    same digest, wherever and however they were installed.
+  - **Documented.** The implementation defines and documents the exact algorithm, which does not
+    depend on any package manager.
+
+The packager uses a supplement only when all three match the package it is about to redistribute.
+
+- **A mismatch on any of the three fails packaging.** This covers, for example, a supplement whose
+  name and version match but whose integrity differs. It never falls back to a nearby version, and
+  it never silently skips the supplement.
+- **Every match is used.** A supplement that matches is always merged into the notices, including
+  when the package also ships some material of its own.
+- **Gaps still fail.** If a dependency lacks required material and no exact supplement matches, the
+  packager stops, exactly as it does today.
+
+### Supplements are immutable build inputs
+
+- **Immutable.** A supplement is never edited in place to cover a different build. A changed
+  package, a new version, or different contents need a new supplement, reviewed again.
+- **No network.** Packaging reads supplements from the packager's own inputs and never downloads
+  anything. Assembling a supplement's content is a separate, offline-reviewed curation step done
+  when the supplement is authored, never during packaging.
+
+### Merging is deterministic and labelled
+
+The notice generator merges package-provided material and supplement material deterministically. The
+same packager version and the same inputs still produce a byte-identical `THIRD_PARTY_NOTICES`
+(ADR 0049).
+
+- **Order.** Within a dependency's entry, package-provided material comes first, then supplement
+  material.
+- **Labelling.** Supplement material is marked as supplied by Ekklesia's reviewed supplement, never
+  presented as if it came from the package.
+- **No other change.** Dependencies are still sorted, line endings normalized, and each dependency
+  keeps its own entry, exactly as before.
+
+### A supplement never changes a dependency's declared licence
+
+`THIRD_PARTY_NOTICES` keeps reporting the licence the dependency itself declares.
+
+- **No override.** A supplement can add material about the components a dependency contains, but it
+  cannot replace, override, or rewrite the dependency's declared licence.
+- **Consistency check.** A supplement records the declared licence it was reviewed against. If that
+  disagrees with the package's actual declaration, packaging fails.
+
+### Legal and compliance determinations are not made here
+
+A supplement can record corresponding-source information, but this ADR does not decide what
+satisfies any licence's source obligation, and neither does the mechanism:
+- the mechanism never asserts that a written offer, a source URL, a mirror, or any other arrangement
+  satisfies a licence;
+- carrying a supplement shows that the reviewed material is present in the package. It does not
+  certify that the package is compliant;
+- for every redistributed binary under the LGPL, the MPL, or any other licence with source or
+  similar obligations, the determination of whether and how those obligations are met is deferred.
+  It must be made, and verified, separately.
+
+ADR 0049's release gate still applies. A package that redistributes such a binary does not become a
+distributable release just because its supplement was merged. It becomes one only once that
+binary's compliance determination has been made and verified.
+
+### Scope
+
+- **Third-party code only.** Supplements apply only to redistributed third-party dependencies,
+  whether bundled or copied into the package. They never apply to the module's own licence or
+  `LICENSE` (ADR 0051), or to incorporated Ekklesia packages.
+- **No package format change.** `packageFormat` stays **1**. A supplement changes only the content of
+  `THIRD_PARTY_NOTICES`, which is already a listed, digested payload file. No metadata field, archive
+  rule, or verifier contract changes.
+
+### The motivating case
+
+`@img/[email protected]` is the first dependency expected to need a supplement. This ADR
+does not curate it. Its supplement will be assembled, reviewed, and merged separately, together with
+the native-target packaging work that redistributes it. The source-obligation determination for its
+LGPL and MPL components remains open, as above.
+
+## Consequences
+
+- A dependency whose package omits required material can be redistributed after review, offline and
+  deterministically, instead of making native packaging impossible.
+- Each supplement is tied to exact package bytes, so a changed or unexpected dependency fails
+  packaging rather than inheriting material reviewed for something else.
+- Ekklesia takes on reviewing and maintaining supplements. Every version bump of a supplemented
+  dependency needs a new reviewed supplement before packaging works again.
+- `THIRD_PARTY_NOTICES` can now contain material that did not come from the dependency's package. It
+  is always labelled.
+- Carrying material and meeting obligations stay separate. Source-availability questions remain open
+  until they are determined per binary.
+
+## Alternatives
+
+- **Download licence material while packaging.** Rejected: packaging must stay offline,
+  deterministic, and independent of a mutable remote source (ADR 0049, ADR 0051).
+- **Extend the standard-text list.** Rejected: standard texts only work when the licence needs no
+  project-specific line. Bundled native libraries need per-project copyright notices, and several
+  different licences.
+- **Match supplements by name and version alone.** Rejected: identical versions can differ in content
+  across registries or rebuilds, and the material was reviewed for specific bytes.
+- **Fall back to the nearest supplemented version.** Rejected: material reviewed for one build says
+  nothing reliable about another.
+- **Let a supplement restate a dependency's licence.** Rejected: the declaration belongs to the
+  dependency's publisher. A supplement that could override it could misrepresent what is being
+  redistributed.
+- **Per-package special cases in the packager** (for example, code that knows about libvips).
+  Rejected: every supplemented dependency would need new code, and review would be split between
+  code and data.
+- **Treat a recorded source URL or written offer as satisfying copyleft obligations.** Rejected for
+  this ADR: that is a legal determination that has to be verified per binary, not assumed by a build
+  mechanism.
+- **Supplements provided by module authors.** Not adopted now: the canonical packager uses only
+  supplements reviewed into Ekklesia. Whether module repositories may contribute their own reviewed
+  supplements is deferred.
+
+## Deferred
+
+- Implementing the mechanism in the canonical packager: the supplement format and storage location,
+  the integrity algorithm, the matching, the merge, and the tests.
+- Curating and reviewing the supplement for `@img/[email protected]`.
+- The legal and compliance determination of source obligations for each redistributed binary, and
+  how a determination is recorded.
+- Whether the packager should refuse, or flag, packages whose supplements note an open determination.
+- Supplements provided by module repositories.
+- Recording which supplements were used in `ekklesia.package.json`, should that ever be needed.

+
+## Context
+
+Modules are independently versioned products in their own repositories (ADR 0021). Yet no module can
+be built outside Ekklesia's monorepo today. Signage's continuous integration clones the platform at
+a pinned commit, places Signage under `modules/signage`, and installs and builds inside that
+workspace, because its Ekklesia dependencies exist only as `workspace:*` packages.
+
+An investigation of the current packages found the following.
+
+- **One coordinated version.** Every `@ekklesia/*` package, and the platform, is version 0.1.2. The
+  release process already bumps them together. The platform reports its Module SDK version, which
+  manifests' `compatibility.moduleSdk` ranges are checked against (ADR 0006), by reading
+  `@ekklesia/module-sdk`'s own package version.
+- **The tarballs already stand alone.** `pnpm pack` rewrites `workspace:*` ranges to exact versions,
+  and each tarball carries only its built `dist`, declarations, and `LICENSE`. But every package's
+  `prepack` runs a command at the monorepo root, and `@ekklesia/typescript-config` is marked
+  `private`.
+- **The SDK exposes everything.** `@ekklesia/module-sdk` re-exports the whole `@ekklesia/contracts`
+  barrel. That includes contracts no module needs, such as authorization and identity, and the
+  legacy Drizzle `ModuleDatabase` type. `@ekklesia/contracts` depends on `drizzle-orm` for that type,
+  so every module install pulls Drizzle in.
+  - Neither the module template nor Signage imports `@ekklesia/contracts` directly.
+- **Frameworks are declared twice.** `@ekklesia/ui` lists `react`, and `@ekklesia/module-sdk` lists
+  `drizzle-orm`, as both a dependency and a peer dependency. That invites a second copy of a runtime
+  that must be single within one module bundle.
+- **The canonical packager assumes the monorepo**, in two ways:
+  - it finds the module's Node.js range only through an enclosing `pnpm-workspace.yaml`;
+  - it decides that an Ekklesia package is the platform's own, not third-party, because its real
+    path does not contain `node_modules`.
+
+  An `@ekklesia/*` package installed from a registry would therefore be treated as third-party.
+  Packaging would omit it from `incorporates` and skip the Module SDK compatibility check.
+- **The registry and its hosts.**
+  - The current private host is a Gitea 1.27.2 server. Its npm registry is enabled for the
+    organization, and that endpoint and the repositories are currently readable anonymously.
+  - pnpm leaves a tarball URL out of its lockfile only when the URL has the canonical
+    `<registry>/<name>/-/<name>-<version>.tgz` form. Gitea advertises another form, so lockfiles
+    produced against Gitea name the Gitea host.
+  - The integrity hashes in those lockfiles are independent of the host.
+
+## Decision
+
+### The npm registry protocol, not a provider
+
+Ekklesia's module-development packages are distributed over the **standard npm registry protocol**,
+and modules install them with ordinary pnpm or npm commands.
+
+- **No provider is part of the architecture.** Not Gitea, GitHub, npmjs, or any other. A module
+  repository depends on the protocol and on a scope-to-registry mapping in normal npm/pnpm
+  configuration.
+- **Gitea may host the private phase.** It is a host for this phase, not a permanent decision.
+- **No host-neutral lockfile or Ekklesia proxy is required.** Moving to another registry may need a
+  one-time change of a module's registry configuration and a regeneration of its lockfile. The
+  integrity hashes keep verifying the package content across such a move.
+
+A module repository's registry configuration is, for example:
+
+```ini
+# .npmrc, committed: where the @ekklesia scope lives, and nothing secret.
+@ekklesia:registry=https://<registry endpoint>/
+```
+
+```ini
+# User or CI configuration, never committed: the credential, from the environment.
+//<registry endpoint>/:_authToken=${EKKLESIA_PACKAGES_TOKEN}
+```
+
+### The public package set
+
+Only packages a module author needs are published. Nothing is published merely because it exists in
+the workspace.
+
+| Category | Packages |
+| --- | --- |
+| Author API | `@ekklesia/module-sdk`, `@ekklesia/module-database`, `@ekklesia/module-ui-sdk`, `@ekklesia/design-tokens` |
+| Tooling | `@ekklesia/module-ui-build`, `@ekklesia/module-pack`, `@ekklesia/typescript-config` |
+| Pre-1.0 component API | `@ekklesia/ui`: publishable, explicitly unstable before 1.0 |
+| Implementation dependency only | `@ekklesia/contracts`: may be published because the packages above depend on it, but it is **not** a supported direct module-author API |
+| Never published | `@ekklesia/core`, the applications, `@ekklesia/module-ui-host`, `@ekklesia/module-template`, and every other platform internal |
+
+### A curated SDK surface
+
+Before the first external publication, the author-facing SDK is narrowed.
+
+- **A curated API.** `@ekklesia/module-sdk` exposes what a module author needs, and no longer
+  re-exports the complete `@ekklesia/contracts` barrel.
+- **No forced Drizzle.** The stable SDK root does not make Drizzle a dependency of modules that do
+  not use it.
+- **No legacy database contract.** The legacy Drizzle database contract (ADR 0016's facade type) is
+  not part of the standalone author-facing surface. Core still serves the legacy facade for its
+  deprecation window (ADR 0050). This decision only keeps its type out of what new standalone
+  modules build against.
+- **Drizzle support lives in one place.** Drizzle-specific helpers belong to the
+  `@ekklesia/module-database` Drizzle adapter (ADR 0050).
+
+### Dependency rules
+
+These rules apply to the published packages:
+
+- **React and ReactDOM** are peer dependencies of the public UI packages, plus development
+  dependencies for those packages' own builds and tests. This does not change ADR 0023: a module UI
+  artifact still bundles React. The peer only ensures there is one React in that bundle, the
+  module's own.
+- **Drizzle** is an optional peer dependency only where the Drizzle adapter needs it.
+- **Real implementation dependencies,** at run time or build time, remain normal dependencies.
+
+These rules apply to a module repository:
+
+- **Runtime and module-code packages** go in `dependencies`: the Author API packages, `@ekklesia/ui`,
+  React, and the module's ORM if it uses one.
+- **Build tooling and configuration** go in `devDependencies`: `@ekklesia/module-ui-build`,
+  `@ekklesia/module-pack`, `@ekklesia/typescript-config`, and type packages.
+
+### Versioning
+
+- **One coordinated version during 0.x.** Every public Ekklesia module-development package uses one
+  release version, equal to the platform release version. The version the platform reports for
+  `moduleSdk` compatibility is therefore the version of the packages a module was built with.
+- **No mixed trains.** Within a published train, Ekklesia-owned dependencies name the coordinated,
+  tested version, never a version from another train.
+- **Ranges in source, exact artifacts in lockfiles.** A module may declare compatible ranges in its
+  source `package.json`; its lockfile pins exact artifacts with their integrity hashes.
+- **`@ekklesia/module-pack` is pinned exactly.** A module repository pins it in its source
+  `package.json`, not only in its lockfile, because its version affects the package it produces.
+- **Independent package versions are deferred.**
+
+### Standalone packaging
+
+- **No monorepo checkout.** A standalone module builds and packages from its own repository and its
+  installed dependencies.
+- **Its own Node.js range.** The module declares its own Node.js compatibility, preferably in
+  `engines.node`, and the canonical packager reads it from there or from an explicit option. It
+  never requires an enclosing `pnpm-workspace.yaml`.
+- **Ekklesia packages recognized by identity.** The canonical packager recognizes Ekklesia-owned
+  installed packages by explicit package identity and metadata, never by workspace path. So
+  `incorporates` and the Module SDK compatibility check (ADR 0049) work the same whether a package
+  came from the monorepo or from a registry. Ekklesia packages are never reported as third-party
+  software (ADR 0051).
+- **No monorepo-root commands at install time.** Publishing workflows for the public packages run
+  their build in the platform's release pipeline. Nothing in a published package runs a
+  monorepo-root command when a consumer installs or packs it.
+
+### Supply chain
+
+- **Immutable versions.** A version is never republished with other content, and never withdrawn to
+  be reused.
+- **Lockfiles.** pnpm lockfile integrity is part of the reproducibility model: modules install with a
+  frozen lockfile.
+- **Release CI proves the tarballs before publication.** It must:
+  1. build and pack the public package set;
+  2. inspect every tarball: only the intended contents, a `LICENSE`, and no `workspace:` range;
+  3. install those tarballs into a clean standalone module fixture, outside any monorepo;
+  4. prove there that the fixture builds, packages with the canonical packager, and verifies.
+
+  Only then are the versions published.
+- **Signing and provenance are deferred.**
+
+### Registry access and the private phase
+
+- **No secrets in module repositories.** Registry configuration for the scope is normal npm/pnpm
+  configuration.
+- **Credentials from the environment.** Read and publish credentials come from environment or user
+  configuration: a read credential in module CI where reads need one, and a publish credential only
+  in Ekklesia's release pipeline.
+- **No permanent provider.**
+- **Verify access before the first publication.** Check the chosen registry's actual private and
+  read-access behaviour first. Ekklesia's packages must not be published unintentionally to a
+  registry that serves them anonymously while Ekklesia is not public.
+
+### The release workflow
+
+During 0.x, public package releases form a **coordinated SDK train** associated with platform
+releases:
+
+1. build;
+2. pack;
+3. standalone tarball smoke (see [Supply chain](#supply-chain));
+4. publish immutable versions;
+5. downstream module CI installs and tests those versions.
+
+### Signage
+
+The intended result is a normal standalone Signage repository:
+- versioned `@ekklesia/*` dependencies;
+- its own lockfile;
+- continuous integration that installs, builds, packages, and verifies on its own.
+
+That CI must not clone Ekklesia or place Signage under `modules/`. The migration itself is a separate
+change.
+
+## Consequences
+
+- A module repository is an ordinary pnpm project. Clone it, install, build, and package it with the
+  canonical packager, with no Ekklesia checkout.
+- Module authors see a smaller, deliberate API, and the platform can change its internal contracts
+  without breaking them.
+- One coordinated version keeps compatibility simple: SDK version X is what platform version X
+  reports and accepts. The cost is republishing unchanged packages with each platform release.
+- A registry move costs each module a configuration change and a lockfile regeneration, but no
+  source change. Package content stays verifiable by integrity hash throughout.
+- Before the first publication, the SDK surface must be curated and the packager's two monorepo
+  assumptions removed. Both are breaking for code that relied on them.
+- ADR 0047, still proposed, assembles a module into the platform workspace to test it. Before it is
+  accepted it must instead consume published packages and canonical module packages, consistent with
+  this decision and with ADR 0048.
+
+## Alternatives
+
+- **Git URL, tag, or commit dependencies.** Rejected: they tie modules to one Git host, need a build
+  on every install because `dist` is not committed, and cannot express version ranges.
+- **Release-asset tarball URLs.** Rejected: each dependency becomes a host-specific URL, and ranges
+  cannot be resolved.
+- **OCI artifacts for packages.** Rejected: npm and pnpm cannot install from them. (A harness image
+  is a different matter; see ADR 0047.)
+- **Vendoring Ekklesia packages into each module repository.** Rejected: the copies drift, updates
+  are manual, and there would be no single canonical SDK.
+- **Requiring host-neutral lockfiles, or an Ekklesia registry proxy that rewrites tarball URLs.** Not
+  required: a one-time lockfile regeneration on a registry move is an acceptable cost, and integrity
+  hashes already keep content verifiable. Ekklesia may still choose a stable endpoint later.
+- **Publishing `@ekklesia/contracts` as a direct author API.** Rejected: it holds platform-wide
+  contracts. Modules get a curated surface through the SDK packages.
+- **Externalizing React from module UI bundles to share one runtime.** Rejected again: ADR 0023's
+  reasoning stands, and peers only prevent duplicates within one bundle.
+- **Independent versions per package now.** Deferred: during 0.x a coordinated train is simpler for
+  module authors and matches how the platform reports its SDK version.
+
+## Deferred
+
+- Provisioning a registry, and its credentials.
+- Public publication on npmjs or any other public registry.
+- Package signing and provenance.
+- Independent package versioning.
+- Dashboard and UI redesign.
+- The Signage migration itself.

+# 0054: Ekklesia's module-development packages are publicly readable before launch
+
+- Status: Accepted
+- Date: 2026-10-08
+- Supersedes (partial): [0053](0053-standalone-module-development-packages.md) — only where it
+  describes the package phase before launch as private: "Gitea may host the private phase", the
+  read credential for module CI in "Registry access and the private phase", and its requirement
+  that packages not be served anonymously while Ekklesia is not public. Every other part of that ADR
+  remains accepted and unchanged: the npm registry protocol, the public package set and its
+  boundaries, the curated SDK, the dependency rules, the coordinated package train, exact release
+  artifacts, standalone module builds, provider portability, supply chain and immutability, and the
+  credential handling for publishing.
+- Related: [ADR 0049](0049-module-package-v1.md)
+
+## Context
+
+ADR 0053 decided how Ekklesia's module-development packages (`@ekklesia/*`) are built, released, and
+distributed over the npm registry protocol. It assumed that the phase before Ekklesia's public
+launch would be private: module CI would carry a read credential where reads needed one, and the
+first publication had to make sure the registry would not serve the packages anonymously.
+
+Checking the chosen host before the first publication showed what keeping the packages private would
+take:
+
+- Gitea 1.27.2 decides package read access by the package **owner's** visibility, never a
+  repository's. The `River_of_Glory_Church` owner is a public organization, so its packages are
+  readable anonymously.
+- That organization's repositories, Ekklesia's source among them, are already publicly readable.
+- The instance allows self-registration, so "limited" visibility, readable by any signed-in user,
+  is readable by anyone who creates an account.
+- Private packages would therefore need a separate private package owner, plus reader accounts and
+  read tokens for every module repository, every module's CI, and every developer.
+
+The project owner has decided that Ekklesia is not secret. Its source is public; the project is
+simply not being launched or promoted yet. Hiding the packages built from that public source would
+protect nothing, and would still cost every module author an account and a token.
+
+## Decision
+
+1. **Ekklesia's module-development packages may be anonymously readable before the project's public
+   launch.** This covers the public package set of ADR 0053: search, metadata, and download.
+2. **Readability is not a launch, and promises nothing more.** Public readability does not mean:
+   - that Ekklesia has been publicly launched;
+   - that the APIs are stable beyond the project's pre-1.0 SemVer policy;
+   - that third-party production use is supported;
+   - that a marketplace or public module ecosystem exists.
+3. **Reading needs no authentication in this phase.** Installing `@ekklesia/*` needs no account,
+   reader account, read token, or authenticated install workflow. A module repository configures only
+   the scope's registry.
+4. **Publication stays authenticated and tightly controlled.** Only Ekklesia's release process
+   publishes, with one dedicated publisher credential that holds nothing beyond package write
+   access, used only by that process, as ADR 0053's credential handling for publishing already
+   requires.
+5. **Published versions stay immutable by Ekklesia policy.** A published version is never deleted or
+   republished with other bytes, whatever the registry technically allows.
+6. **The current Gitea owner is an acceptable host.** The `River_of_Glory_Church` package namespace
+   on the current Gitea may host this phase, as long as publishing permission stays restricted to
+   the publisher. No private package organization is needed.
+7. **A public launch is a separate decision.** Launching or promoting Ekklesia publicly, and anything
+   that changes for its packages then, is a product and release decision this ADR does not make.
+
+## Consequences
+
+- **Module authors and module CI need no Ekklesia credential.** The committed `.npmrc` scope mapping
+  is the whole registry configuration. ADR 0053's example of a read credential in user or CI
+  configuration is no longer needed in this phase.
+- **ADR 0053's pre-publication access check changes meaning.** It now confirms that anonymous reads
+  work as intended and that publishing is refused without the publisher's permission, rather than
+  that reads are private. The disposable-registry suite proves both, and the publication tool can
+  require an anonymous download to match each published artifact.
+- **Restricting publishing is now the whole access boundary**, so the publisher credential's scope,
+  where it is held, and who can reach it matter all the more.
+- **Making the packages private again would be a new decision.** Package names, versions, and
+  contents already published stay public, because a published version is never deleted.
+
+## Alternatives considered
+
+- **A private package organization on the same Gitea.** Rejected: it hides nothing that is not
+  already public in the source, and it requires reader accounts and tokens for every module
+  repository, its CI, and every developer.
+- **"Limited" package visibility.** Rejected: with self-registration open, anyone can read anyway,
+  while the configuration suggests otherwise.
+- **Requiring sign-in for the whole instance.** Rejected: it would also hide the public
+  repositories.
+- **Another registry for a private phase.** Unnecessary once reads are public.

+# 0055: Native redistributable packages carry corresponding-source artifacts
+
+- Status: Accepted
+- Date: 2026-10-09
+- Extends: [0049](0049-module-package-v1.md). ADR 0049 withholds distributable-release status from a
+  package until its licence handling is proven. This ADR adds what proving it means for a native
+  package that redistributes copyleft code: a sibling corresponding-source artifact, and a
+  fail-closed gate for public distribution. Module Package v1 is unchanged, and `packageFormat`
+  stays **1**.
+- Decides: the item [ADR 0052](0052-reviewed-license-supplements.md) deferred, "the legal and
+  compliance determination of source obligations for each redistributed binary, and how a
+  determination is recorded", as a project policy. Reviewed supplements are unchanged in purpose
+  and format.
+- Related: [ADR 0051](0051-module-package-license-material.md), whose rules for a module's own
+  licence are unchanged.
+
+## Context
+
+A native Module Package (ADR 0049) copies native dependencies into its `node_modules` exactly as
+built. The first one, the packager's native proof with sharp, redistributes
+`@img/sharp-libvips-linux-x64`. That is one shared object with about 29 libraries built into it.
+Several are under the GNU LGPL, and cairo and some Rust crates are under the MPL.
+
+ADR 0052 made the licence and notice side work. A reviewed supplement adds the licence, copyright,
+and notice files the package omits, with the exact upstream source each came from. But ADR 0052 was
+explicit that carrying material is not meeting obligations. The LGPL and the MPL also oblige whoever
+distributes the binary to make the corresponding source available. For a library linked into a
+larger work, that includes what a recipient needs to rebuild the library and use a modified version.
+Recording upstream URLs does not do that: URLs move, tags are rewritten, and a mirror is somebody
+else's promise.
+
+Until this was decided, every native package containing such components was blocked from public
+distribution, and the blocker had no defined way to be lifted.
+
+## Decision
+
+### Native packages may contain copyleft native dependencies
+
+A native Module Package may redistribute native dependencies under the LGPL, the MPL, or a similar
+licence with source obligations. It may be **distributed publicly** only when it is released
+together with a **corresponding-source artifact** that meets this ADR. A package whose artifact
+cannot be produced and verified is not approved for public distribution.
+
+This is Ekklesia's **project compliance policy**: a conservative rule the project holds itself to.
+It is not legal advice, and it is not legal certification. Repository review of the artifact, its
+inputs, and its instructions is project and code review. It does not replace professional legal
+review, and nothing built from this ADR may claim that it does.
+
+### Supplements and source artifacts do different jobs
+
+- **A reviewed supplement (ADR 0052)** identifies and verifies the licence and notice material for a
+  redistributed binary. It travels inside the package, in `THIRD_PARTY_NOTICES`.
+- **A corresponding-source artifact** carries the source, patches, build definitions, and rebuild
+  and relink instructions for the covered native components. It travels beside the package, as a
+  separate release artifact.
+
+A supplement alone never satisfies the source-availability policy. A source artifact never replaces
+the supplement or `THIRD_PARTY_NOTICES`.
+
+### What the artifact contains
+
+For each covered native dependency the package redistributes, the artifact contains:
+
+- the exact source the binary was built from, as bytes, not as references:
+  - its build definitions;
+  - the source archive of every library compiled into it;
+  - every patch the build applied;
+  - every source package a language package manager resolved for the build;
+  - the source of any runtime library the toolchain linked into it;
+- the licence and copyright material: the reviewed supplement, and the files inside the sources;
+- **instructions** that are technically actionable. They name what the artifact corresponds to and
+  its target, and say how to apply the patches and rebuild the covered library. They also say how a
+  rebuilt or modified library replaces the redistributed one in the installed module, and which
+  toolchain and configuration to use, or point to the included build definitions;
+- a deterministic, machine-readable manifest of every component and file, each with its digest,
+  plus the human-readable provenance.
+
+Components that are not part of the binary are left out, each with its reason recorded: build-only,
+test-only, or another platform's. The exception is a build-time input needed to rebuild the covered
+library, such as a source package a build script requires. That is included and marked as
+build-only. Host system libraries and general-purpose build tools are not redistributed, and the
+instructions name the versions they need.
+
+### It is tied to exact inputs, and verified before it is written
+
+- **Bound to the binary.** An artifact names each covered dependency by package name, version, and
+  the content digest a supplement is matched by (ADR 0052). It names the module identity and target
+  of the package it accompanies. An artifact for one version of a binary never satisfies another.
+- **From reviewed inputs only.** The inputs come from a checked-in, reviewed **source recipe** per
+  covered dependency version. The recipe records each component's name, version, origin,
+  relationship to the binary, and licence material, and each source file's and patch's size and
+  SHA-256.
+- **Acquisition is separate from construction.** Obtaining the recorded bytes may use the network,
+  in an explicit preparation step that stores them in a local cache keyed by content digest.
+  Constructing the artifact is offline. It reads only the cache and checked-in files, verifies every
+  byte against the recipe before writing anything, and never fetches or trusts a current upstream
+  response.
+- **Deterministic.** The same inputs produce the same artifact, byte for byte, in any working
+  directory: normalized relative paths, fixed ownership, modes, and timestamps, sorted entries, and
+  no machine-specific path.
+
+### Binary and source are linked by recorded digests
+
+A public release of a native package with covered components consists of sibling artifacts:
+
+- the Module Package archive and its SHA-256 (ADR 0049);
+- the corresponding-source archive and its SHA-256;
+- machine-readable **redistribution metadata** recording:
+  - the package archive's name and SHA-256;
+  - the module identity and target;
+  - each covered dependency's name, version, licence, and content digest;
+  - the supplement and recipe it was assembled from;
+  - the source archive's name and SHA-256, and the SHA-256 of its manifest;
+- a **release notice**, displayed alongside the binary wherever it is offered. It says, in
+  substance, that the release includes third-party software under licences including the GNU LGPL
+  or the MPL, and that corresponding source and build and relink materials for the covered native
+  dependencies are in the accompanying artifact, named by its exact file name and SHA-256.
+
+A reviewer can therefore tell exactly which source artifact corresponds to which redistributed
+binary, from digests, without guessing from file names. The source archive is never placed inside
+the Module Package. `THIRD_PARTY_NOTICES` stays as it is, and never duplicates the source.
+
+### Public distribution fails closed
+
+Building and testing packages stays unrestricted: the packager produces native packages exactly as
+before, for development, CI, and private use. **Public redistribution approval** is a separate gate.
+For a package intended for public distribution, the gate requires that:
+
+- the package's native dependency inventory is known;
+- every covered dependency has its reviewed supplement and source recipe;
+- the corresponding-source artifact is present;
+- every digest matches;
+- the artifact's manifest validates against the recipe and the archive's own contents;
+- the release notice names the exact artifact.
+
+If any requirement fails, approval fails. Bundled (not copied) code under such a licence is not
+handled by this mechanism, so the gate refuses it rather than approving it.
+
+### Retention, and no rewriting history
+
+- Ekklesia keeps a release's corresponding-source artifact for as long as it distributes, or
+  supports access to, the matching binary release. Nothing deletes one automatically while that
+  binary remains available.
+- The bytes of a source artifact for an existing binary release are never replaced under the same
+  identity.
+- A correction is a new release, or an explicitly versioned compliance artifact that the
+  redistribution metadata names. History is never silently replaced.
+
+### What this ADR does not do
+
+- It does not change any module's own licence, or ADR 0051's rules for it. The module's own source
+  obligations are met by the module's own repository, as before.
+- It does not make **runtime downloading** an acceptable workaround. Fetching a copyleft library at
+  run time instead of redistributing it moves the obligation rather than meeting it, makes
+  installations depend on a third party, and breaks ADR 0048's self-contained installed modules. It
+  is not the preferred path.
+- It does not change Module Package v1, the verifier's acceptance of a package, or the content of
+  existing supplements.
+
+## Consequences
+
+- Native modules that need copyleft native libraries, starting with sharp's libvips, can be
+  distributed publicly under a defined, checkable policy, instead of being blocked indefinitely.
+- Each covered dependency version needs a reviewed source recipe, as it needs a reviewed supplement.
+  A dependency bump needs both before public distribution works again.
+- Releases carry an artifact many times larger than the package itself (about 200 MB for libvips
+  1.3.4, against a 9 MB package), and Ekklesia commits to retaining it.
+- Constructing the artifact needs the verified source cache. Acquisition happens once per recipe,
+  not on every build.
+
+## Alternatives
+
+- **Treat supplements, source URLs, or a written offer as sufficient.** Rejected: URLs and offers
+  depend on third parties and on time. This policy requires the source itself, retained with the
+  release.
+- **Put the source inside the Module Package.** Rejected: installations would store hundreds of
+  megabytes they never need, and the package format would change for a distribution concern.
+- **Download sources while constructing the artifact.** Rejected: a release would depend on mutable
+  remote responses. Acquisition is explicit and verified, and construction is offline.

+# 0056: A device credential lasts while the device is in use
+
+- Status: Accepted
+- Date: 2026-10-12
+- Supersedes: the "Session lifetime" section of [0036](0036-managed-device-identity-and-pairing.md).
+  Everything else in ADR 0036 — the device as its own principal, pairing, revocation on every
+  request, re-pairing as a new identity — is unchanged.
+
+## Context
+
+ADR 0036 gave a device credential a fixed 180 days from pairing. The intent was that a screen on a
+ceiling should not need re-pairing on a short cycle, and that an abandoned screen should eventually
+stop being an identity.
+
+A fixed horizon does the second and fails the first. Every screen in the building expires on the
+anniversary of its pairing whether or not it was in use the day before, and drops to a pairing code
+in front of the congregation until someone with Dashboard access walks to it. For screens paired
+together, that is every screen at once. Nothing about a working, unrevoked screen is less trustworthy
+on day 181 than on day 179; only the calendar changed.
+
+## Decision
+
+**The 180 days are an idle window, not a lifetime.** A device credential is accepted while the
+device was last seen less than 180 days ago (or, if it has never been seen, was paired less than 180
+days ago). `lastSeenAt` already moves forward on authenticated device requests (throttled to one
+write per 15 minutes), so the server-side window slides with use and needs no new column or
+migration.
+
+**The browser's copy is renewed by the host, not rotated.** The display descriptor —
+`GET /api/v1/module-displays/<module>`, which every display requests when it starts, when it
+reconnects, and periodically while it runs — re-issues the device cookie that authenticated the
+request with a fresh 180-day `Max-Age` and the same attributes as at pairing (`HttpOnly`,
+`SameSite=Strict`, host-only, `Path=/`, `Secure` on https). The value is unchanged.
+
+Renewal happens only for a request that already resolved to a live, unrevoked device. A revoked,
+expired, or unknown credential is anonymous, as before, and is never renewed; a person viewing a
+display never receives a device cookie.
+
+**Revocation remains the boundary.** It is still checked on every request, and an administrator's
+revoke still takes effect immediately.
+
+## Why not rotate
+
+Rotation (issue a new value, invalidate the old) would bound how long any one stolen value works and
+could reveal a cloned credential. For an unattended screen it trades that for a new way to strand
+the display: a renewal response lost to a network drop, a power cut, or a browser that never
+persisted the new cookie leaves the screen holding a dead credential and showing a pairing code,
+which is the failure this decision exists to remove. A refresh-token scheme with overlap windows
+could avoid that, at the cost of real complexity in the one place mistakes are invisible until a
+wall goes dark. That is not justified while revocation is immediate and a device principal can only
+read the displays it was paired for.
+
+## Consequences
+
+- A screen that is used at least once every 180 days stays paired until an administrator revokes
+  it. An abandoned screen still stops being an identity 180 days after it was last seen.
+- Existing credentials need no migration. A screen paired under the fixed rule is renewed the next
+  time it requests its descriptor, provided its browser still holds the cookie.
+- A stolen device credential stays usable for as long as anyone keeps using it, until it is revoked.
+  Under ADR 0036 it was usable for at most 180 days from pairing. The exposure is bounded by what a
+  device may do — the display permissions of the module it was paired for, never a person's access
+  — and by revocation. Operators can see each device's last-seen time and revoke anything
+  unexpected.
+- A credential is not bound to a browser or network. Like a human session cookie, whoever presents
+  it is the device.
+
+## Alternatives
+
+- **Keep the fixed 180 days.** Rejected: every in-use screen fails on a schedule, and screens paired
+  together fail together.
+- **Never expire.** Rejected: an abandoned or forgotten screen would remain an identity forever, and
+  its credential would never stop working without someone remembering to revoke it.
+- **Rotate on renewal.** Rejected for now; see above.
+- **Renew on every authenticated response.** Rejected: principal resolution happens deep in shared
+  middleware that never writes responses. One endpoint every display already requests periodically
+  is enough, and keeps the behaviour in one visible place.

+```
+
+1. **Version set.** A `chore(release): prepare X` pull request sets the release version: the root
+   `package.json`, every platform workspace package (the module template versions as a module, not
+   with the platform), the image build example in `deploy/README.md`, and the standalone fixture's
+   exact `@ekklesia/module-pack` pin and `@ekklesia/*` ranges
+   (`tests/fixtures/standalone-module/package.json`). The tag must point at a commit that carries
+   the version it names.
+
+   A minor version (0.x → 0.(x+1)) is a breaking release before 1.0, so manifests that declare
+   `compatibility.platform` and `compatibility.moduleSdk` as `^0.x.0` no longer match it. In the
+   same pull request, move to the new range every module built for this release (the template, the
+   standalone fixture, the native proof module), the test fixtures that model a module of the
+   current release or the current platform, and the module-development guide's examples. A patch
+   version changes none of these.
+2. **Build and test.** `pnpm verify`, the integration suite, and the deploy smoke, as for any change.
+3. **Pack the public package train.** `pnpm packages:release` (below).
+4. **Standalone consumer proof.** A module outside the repository consumes exactly those
+   artifacts (below).
+5. **Publish the exact train.** By hand, with the `Publish packages` workflow on the version-set
+   commit on `main` ([Publishing the train](#publishing-the-train)). It publishes the artifacts its
+   own run's gate (steps 3 and 4) proved, and nothing else.
+6. **Tag and release.** Unchanged: the maintainer tags the merge commit of the version-set pull
+   request. Nothing here creates, moves, or requires a tag.
+
+Steps 2 to 4 run in CI on every pull request and on `main`, and CI also publishes each proven train
+to a disposable registry (`package-publication`), never the real one. Step 5 runs only when a
+maintainer starts it.

+## The public package train
+
+| Package | Role |
+| --- | --- |
+| `@ekklesia/module-sdk`, `@ekklesia/module-database`, `@ekklesia/module-ui-sdk`, `@ekklesia/design-tokens` | author API |
+| `@ekklesia/module-ui-build`, `@ekklesia/module-pack`, `@ekklesia/typescript-config` | tooling |
+| `@ekklesia/ui` | publishable, pre-1.0 component API |
+| `@ekklesia/contracts` | implementation dependency of the packages above: published only because they need it, never a supported direct dependency of a module |
+
+The list lives in `scripts/package-release.ts` (`PUBLIC_PACKAGES`). Every other workspace package is
+`private`, and the release builder refuses to run if a package outside the list is publishable or
+carries the `module-development` distribution marker.
+
+- **One version.** Every package in the train has the platform release version.
+- **One train.** Every `@ekklesia/*` dependency in a packed manifest names a package of the same
+  train at exactly that version. `workspace:` ranges become those exact versions when packed.
+- **No independent versions.** A package cannot be released on its own.
+
+## Producing the release artifacts
+
+```bash
+pnpm packages:release          # writes .package-release/ekklesia-packages-<version>/
+```
+
+`scripts/package-release.ts`:
+
+1. **Refuses a modified source tree, before it builds anything.** A release is built from a
+   commit. A tree is clean when `git status` shows no change to a tracked file and no untracked file
+   that Git does not ignore. Ignored files are build output and package-manager state:
+   `node_modules`, `dist`, `.turbo`, and pnpm's `.pnpm-store`, which pnpm creates at the checkout's
+   root when the checkout is its own mount (a CI runner's workspace volume). The failure lists every
+   change. `--allow-modified` exists for local development only; its manifest then says
+   `"modified": true`, and such a release must never be published.
+2. **Checks the release set and versions** in the workspace.
+3. **Rebuilds from clean output.** It removes each public package's `dist/` and rebuilds without the
+   build cache, so output from a deleted source file can never ship. It then checks the source tree
+   again: a build that changed a tracked file, or wrote an untracked one Git does not ignore, fails
+   the release, because what is packed must be exactly the commit.
+4. **Packs each package with `pnpm pack`.** Pack-only pnpm hooks (`scripts/lib/pack-hooks.cjs`)
+   apply, never the workspace's install settings ([Reproducibility](#reproducibility)).
+5. **Inspects every tarball.** It checks:
+   - the expected name, version, and file name;
+   - a `LICENSE`, and only the `files` the manifest declares, each built file with the source it
+     came from, and no source, test, or configuration file;
+   - no `workspace:` range, no `devDependencies`, no `publishConfig`, and no install-time lifecycle
+     script;
+   - only public `@ekklesia/*` dependencies, at the train's version;
+   - the distribution marker;
+   - no local path (the checkout, the home directory, or the temporary directory) in any file.
+6. **Checks the set.** The release must hold exactly the expected tarballs: none missing, none extra.
+7. **Writes the release directory only when everything passed,** in one step. It refuses to
+   overwrite one that exists.

+```bash
+pnpm test:package-release      # scripts/test-package-release.sh

+
+1. **Builds the train** from this checkout. Nothing is built before it.
+2. **Builds it again** from a second worktree of the same commit at another absolute path, and
+   requires both release directories to be byte-identical: every tarball, `SHA256SUMS`, and the
+   manifest.
+3. **Builds Core's verifier**, then **runs the standalone consumer proof** (`scripts/test-standalone-module.sh --release <dir>`) on
+   that release:
+   - **The release is checked first.** Every artifact must match the manifest's size, SHA-256, and
+     integrity, and the release must not be built from a modified tree.
+   - **The fixture module installs from those tarballs alone.** It is
+     `tests/fixtures/standalone-module`, copied outside the repository. Every `@ekklesia/*`
+     package, direct or transitive, resolves to its release tarball. There is no workspace link and
+     no Ekklesia source checkout. The install runs offline: third-party packages come from the
+     workspace install's own pnpm store, named explicitly because pnpm otherwise picks a store per
+     file system, so no registry is involved at all.
+   - **The lockfile matches the release.** It must record each artifact's own integrity. The module
+     then reinstalls from the lockfile alone with `--frozen-lockfile`.
+   - **The install has the right shape.** There is no `drizzle-orm`, and exactly one `react`, which
+     `@ekklesia/ui` resolves to as well. `@ekklesia/contracts` is installed only transitively: it is
+     not in the module's `package.json` and not directly under `node_modules/@ekklesia`. Every
+     installed `@ekklesia/*` package, `module-pack` included, is exactly the release version, and
+     the fixture pins `module-pack` exactly.
+   - **The module builds.** It typechecks with `skipLibCheck: false`, so every published declaration
+     it reaches is checked, then builds its backend and UI.
+   - **It packages and verifies.** It is packed with the release's own `ekklesia-pack-module`, with
+     no workspace file present. Core's verifier then verifies it. The package must:
+     - incorporate the train's packages at the release version;
+     - name the release's module-pack as its packager;
+     - credit no Ekklesia package and exactly one React;
+     - contain no local path.
+
+## Reproducibility
+
+Two builds of the same commit produce byte-identical tarballs, and CI proves it on every run.
+
+- **pnpm normalizes the tar entries.** Every entry gets the fixed modification time 1985-10-26, owner
+  0, and a mode of 0644, or 0755 when executable. The gzip header records no time.
+- **The build output is deterministic,** and source maps use relative paths.
+- **One nondeterminism came from pnpm itself.** pnpm rewrites `workspace:` ranges concurrently and
+  inserts each dependency as its lookup resolves. A package with more than one `workspace:`
+  dependency in one field could therefore be packed with those keys in a different order. Builds
+  from two checkouts of one commit differed in exactly that way: `@ekklesia/module-pack`'s
+  `package.json` ordered `@ekklesia/module-sdk` and `@ekklesia/module-database` differently.
+  - **The fix is pnpm's own hook.** The pack-only `beforePacking` hook puts each dependency map back
+    in the source `package.json`'s key order. It changes no name, range, or field. The tarball stays
+    an ordinary `pnpm pack` tarball.
+  - **The inspection enforces it.** It fails any packed map whose order differs from its source.
+- **The hook also drops `devDependencies`** from packed manifests. A consumer never installs them,
+  and a tooling package's test-only development dependencies named private workspace packages
+  outside the train.
+
+**What reproducibility does not cover:**
+- The module package the consumer proof builds is deterministic only for a fixed install layout.
+  pnpm names a `file:` tarball's install directory after its path, and bundlers keep those names in
+  comments. So the proof always installs from the same relative path. From a registry, the directory
+  is simply `<name>@<version>`.
+- Byte identity is proven for the pinned toolchain: Node.js from `.node-version`, and pnpm from
+  `packageManager`. Another Node.js or zlib build may compress differently. Each artifact's
+  integrity is recorded either way, and that, not byte identity, is what a publication step must
+  verify.

+`.github/workflows/publish-packages.yml` (Actions → Publish packages → Run workflow, on `main`,
+with the release version). Nothing else can start it: no pull request or push does, and CI holds no
+registry credential at all.
+
+1. **The gate.** `package-release` runs the same credential-free gate as CI (build, reproduce,
+   consume) and hands the proven release on as a workflow artifact, with its manifest's SHA-256.
+2. **The publish job.** It builds and installs nothing. It downloads the artifact and runs
+   `scripts/publish-package-train.ts` with the secret `EKKLESIA_PACKAGES_PUBLISH_TOKEN`, which only
+   this step receives.
+3. **The publication record** is kept as an artifact of the run.
+
+### What the publication tool does
+
+`scripts/publish-package-train.ts` publishes exactly the `.tgz` files in the release directory. It
+never builds, packs, or edits a package, and it never deletes, unpublishes, or overwrites anything.
+
+1. **Validates the whole train before sending anything.** The manifest must be the one the gate
+   proved (`--manifest-sha256`), for the requested version and this commit (`--revision`), from a
+   clean tree (`"modified": false`), with exactly the nine expected packages. Every artifact's file
+   name, size, SHA-256, integrity, `SHA256SUMS` line, and the `package.json` inside it must match.
+2. **Publishes in dependency order.** Each package comes after the train packages it depends on,
+   then alphabetically. For each package:
+   - **absent:** `npm publish <file.tgz>` under the staging dist-tag `ekklesia-staging`, given the
+     artifact's absolute path (npm runs in a temporary directory of its own), after the file is
+     checked once more against the manifest. npm sends the file's own bytes and runs no script for a
+     file; the registry checks them against their integrity and stores them as they are;
+   - **present with the same bytes:** accepted as already published, and verified;
+   - **present with other bytes:** a hard stop. Nothing is deleted or overwritten, nothing after it
+     is published, and the version is burned ([Immutability](#immutability)).
+3. **Reads every package back.** The registry's metadata must name the package and version, report
+   the artifact's integrity, and list the same `dependencies`, `peerDependencies`,
+   `optionalDependencies`, and `bin` as the tarball's `package.json` (npm writes `bin` paths without
+   a leading `./`). Its tarball URL must be on the configured registry, and the tarball it serves must
+   be the release artifact, byte for byte. With `--require-public-read`, an anonymous download must
+   give the same bytes too. A package is published only once all of that holds.
+4. **Moves `latest` last.** Only when all nine are verified does `latest` move to the train, never
+   backwards past a newer version. The train is published when every package's `latest` agrees.
+5. **Writes the publication record** (`--record`).
+
+A rerun is always safe. It publishes only what is missing, accepts what is already there and
+identical, and moves only the tags that are not yet right. A train interrupted after five packages,
+or after four tags, finishes on the next run. No retry ever deletes anything.
+
+### The publication record
+
+Evidence that one train was published, not a second package catalog, and never a secret:
+
+```json
+{
+  "publicationRecord": 1,
+  "packageTrain": { "version": "0.2.0", "revision": "<commit>", "manifestSha256": "<hex>" },
+  "registry": "https://git.zayin.net/api/packages/Zayin/npm/",
+  "finalTag": "latest",
+  "completedAt": "<ISO time>",
+  "packages": [
+    {
+      "name": "@ekklesia/contracts",
+      "version": "0.2.0",
+      "file": "ekklesia-contracts-0.2.0.tgz",
+      "outcome": "published",
+      "artifact": { "sha256": "<hex>", "integrity": "sha512-…", "size": 87379 },
+      "registry": { "tarball": "<url>", "sha256": "<hex>", "integrity": "sha512-…", "publicRead": true },
+      "finalTag": "moved",
+      "distTags": { "ekklesia-staging": "0.2.0", "latest": "0.2.0" }
+    }
+  ]
+}
+```
+
+`outcome` is `published` or `already-present`. `finalTag` is `moved`, `already-current`, or
+`kept-newer` (a newer version already holds `latest`).
+
+### Credentials
+
+- **One credential:** `EKKLESIA_PACKAGES_PUBLISH_TOKEN`, a repository Actions secret, used only by
+  the publish step. Nobody needs a token to read or install.
+- **The publisher** is a dedicated account, member only of a `Zayin` team whose one
+  permission is Packages: Write. Its token has only the `write:package` scope. Gitea's
+  `write:package` also allows deleting packages; the tool never does, and nothing else uses the
+  token.
+- **No token in git or in an `.npmrc`.** The tool writes a temporary npm configuration that refers to
+  the variable (`_authToken=${EKKLESIA_PACKAGES_PUBLISH_TOKEN}`), ignores every user, global, and
+  project npm configuration, sends the token only to the registry itself, and removes the
+  configuration afterwards.
+- **What remains trusted:** Gitea gives repository secrets to workflows run for pull requests from
+  branches of this same repository, so anyone who can push a branch here could read the secret
+  through a changed workflow. Keep write access to this repository to the maintainers.
+
+### Immutability
+
+Gitea refuses to upload a version that exists (409). But it lets anyone with package write
+permission delete a version, deletion leaves nothing behind, and an owner's package cleanup rules
+can delete versions on a schedule. So immutability is Ekklesia's policy, not the registry's
+guarantee:
+
+- **A published version is never deleted,** by anyone, for any reason short of a security incident.
+- **A version number is never reused with other bytes.** A version found on the registry with other
+  bytes is burned: investigate how it got there, and publish the train under a new version.
+- **No package cleanup rule** may be configured for the `Zayin` owner.
+- **The publisher never deletes.** The tool has no delete, unpublish, or overwrite, and its tests
+  check that.
+
+Module lockfiles record each package's integrity, so a replaced package would fail every install of
+it, rather than install silently.
+
+### Moving to another registry
+
+Only configuration changes: the registry URL (the workflow's `EKKLESIA_PACKAGES_REGISTRY`), the
+publisher credential, and modules' `@ekklesia:registry`. Modules then regenerate their lockfiles,
+because Gitea's tarball URLs are its own. Package sources, the train, its manifests, and every
+artifact already built stay as they are; the same bytes keep the same integrity.
+
+### Proving the publication machinery
+
+`pnpm test:package-publication` (`scripts/test-package-publication.sh`, the CI `package-publication`
+job) publishes a real release train to a disposable Gitea 1.27.2 configured like the real one:
+public owners, a publisher team, and an outsider. In CI it publishes the very artifact the
+`package-release` job handed on, after checking its manifest hash. It proves:
+
+- anonymous search, metadata, and download work;
+- publishing without credentials, or by a user outside the publisher team, fails;
+- the round trip is byte-identical, also anonymously;
+- the registry refuses a second upload of a published version;
+- a train interrupted before its sixth package resumes, verifying the five and publishing the rest,
+  with `latest` untouched until all nine are verified;
+- a version already published with other bytes stops the train, deleting and overwriting nothing,
+  and publishing nothing after it, on every retry;
+- a train interrupted while moving `latest` converges on a rerun, moving only the missing tags.
+
+### The first publication
+
+The first train published is **0.2.0**, the next platform release, not 0.1.2. The `v0.1.2` tag
+predates the curated SDK and this release tooling, so packages built now and called 0.1.2 would
+claim to be source that 0.1.2 never contained.
+
+Before it, an administrator of the Gitea instance:
+
+1. creates the dedicated publisher account;
+2. creates a `Zayin` team, for example `package-publishers`, with only the Packages
+   unit at Write, and adds the account to it;
+3. creates a token for the account with only `write:package`, and stores it as the repository
+   Actions secret `EKKLESIA_PACKAGES_PUBLISH_TOKEN`;
+4. checks that the owner has no package cleanup rule.
+
+Then the release proceeds as usual: the version-set pull request merges, a maintainer starts
+Publish packages on `main` with that version, and tags the commit once the train is published.

+
+A module does not need an Ekklesia checkout. Do not clone Ekklesia and put your module in its
+`modules/` directory: your module is its own repository, and it depends on Ekklesia's
+module-development packages like any other npm packages.
+
+The packages are **publicly readable**
+([ADR 0054](../architecture/decisions/0054-public-package-reads-before-launch.md)): installing them
+needs no account, no token, and no access to Ekklesia's Gitea. That is not a public launch, and it
+promises no API stability beyond the pre-1.0 SemVer policy. Only Ekklesia's release workflow can publish them. Point the `@ekklesia` scope at
+the registry in your repository's committed `.npmrc`; that is all the configuration there is:
+
+```ini
+@ekklesia:registry=https://git.zayin.net/api/packages/Zayin/npm/
+```
+
+Then the module builds and packages like any other:
+
+```bash
+pnpm install
+pnpm build
+pnpm exec ekklesia-pack-module --module . --target any --out ../packages \
+  --license-file ./LICENSE --source-revision "$(git rev-parse HEAD)"
+```
+
+Before 1.0, a minor version may change these APIs (the project's SemVer policy). Pin the train you
+build against with ranges in `package.json` and exact versions in your lockfile.

+- **One coordinated version.** Every Ekklesia module-development package has the same version,
+  equal to the Ekklesia release it belongs to, and the platform checks your manifest's
+  `compatibility.moduleSdk` against it. Ranges in your `package.json` are fine; your lockfile pins
+  exact artifacts, and you install with a frozen lockfile.
+- **Pin `@ekklesia/module-pack` exactly** in `package.json`, not only in the lockfile: its version
+  decides the package it produces.
+- **`engines.node` is required.** The packager records your module's supported Node.js range from
+  `engines.node` in your `package.json`, and refuses to package without it
+  (`MODULE_PACK_RUNTIME_UNKNOWN`). It never looks for a workspace file.
+- **No Drizzle unless you use it.** The Module SDK does not install Drizzle. A module that uses the
+  Drizzle adapter, `@ekklesia/module-database/drizzle`, adds `drizzle-orm` to its own
+  dependencies; it is an optional peer of that adapter only.
+- **One React.** `@ekklesia/ui` takes React as a peer, so your bundle contains one React, your own.
+  Your UI artifacts still bundle it
+  ([ADR 0023](../architecture/decisions/0023-module-ui-build-pipeline.md)).
+- **esbuild's install script.** The UI build and the packager use esbuild, which runs an install
+  script. With pnpm, allow it in your repository's `pnpm-workspace.yaml`:
+
+  ```yaml
+  allowBuilds:
+    esbuild: true
+  ```
+- **Lockfiles name the registry.** pnpm records Gitea's tarball URLs in your lockfile. If the
+  packages ever move to another registry, change `@ekklesia:registry` and regenerate the lockfile;
+  nothing else changes, and the integrity of every package stays the same.
+- **TypeScript.** Extend the shared configurations by package name, for example
+  `"extends": "@ekklesia/typescript-config/node.json"` for the backend and
+  `@ekklesia/typescript-config/browser-react.json` for the UI.
+
+Packaging and verification work exactly as for a module in this repository
+([Packaging your module](#packaging-your-module)). The packager recognizes Ekklesia's packages by
+their identity, not by where they are installed, so they are recorded under `incorporates` and never
+credited as third-party software, wherever they came from.
+
+Ekklesia proves this on every CI run: `pnpm test:package-release` builds the public packages of a
+release as one train of tarballs, proves two builds identical, and installs exactly those tarballs
+into a module outside the repository (`tests/fixtures/standalone-module`), with no workspace link
+and no registry, then typechecks, builds, packages, and verifies it. Those exact artifacts are what
+the release publishes ([Releases and the public package train](../development/releases.md)).

+    packaging.
+  - **`runtime` is read from the binaries themselves.** It records the Node-API version your addons
+    declare (or the exact Node.js ABI of an ABI-specific addon) and the newest glibc symbol version
+    any copied binary needs. A native target for a module with no native addon is refused: use
+    `any`.
+- **A native package fits one environment.** A `linux-x64-glibc` artifact runs only on Linux,
+  x86-64, glibc hosts that meet its recorded glibc and Node-API minimums. The verifier checks all of
+  that before it loads anything. Other operating systems and CPUs, including ARM, are not supported
+  yet.
+- **Your module's licence.** Your source `package.json` must contain a non-empty string SPDX
+  expression. The packager validates its syntax, rejects `UNLICENSED`, and copies it unchanged to
+  the required `ekklesia.package.json.license`. `--license-file` is also required: it names the
+  regular file whose exact bytes become the root `LICENSE` payload and inventory entry. The
+  packager never searches parent directories, guesses text from the expression, or downloads it.
+- **Third-party licences.** `THIRD_PARTY_NOTICES` separately credits every third-party package your
+  bundles contain, with its declared licence and the licence and notice files it ships. A dependency
+  that declares no licence fails packaging, and so does one that ships no licence text, unless its
+  licence's standard text is complete without a copyright line (Apache-2.0, which the packager then
+  supplies and says so). The module itself is not added to this notice file. Bundled Ekklesia
+  packages remain listed in `ekklesia.package.json` under `incorporates`; one applicable AGPL text
+  is sufficient for current official modules. An Ekklesia package is one named `@ekklesia/*` whose
+  `package.json` also carries `"ekklesia": { "distribution": "module-development" }`, whether it is
+  linked from this repository or installed from a registry; a package with only the name is
+  third-party.
+- **Reviewed licence supplements.** Some dependencies omit material that redistribution requires.
+  For one of those, the packager adds material from a reviewed supplement checked in with it, after
+  the package's own material and labelled as such
+  ([ADR 0052](../architecture/decisions/0052-reviewed-license-supplements.md)).
+  - **Exact match.** A supplement is used only for an exact package name, version, and content
+    digest. The digest covers the redistributed files' relative paths and bytes, and is documented in
+    `packages/module-pack/src/supplements.ts`. Any mismatch fails.
+  - **What it does not do.** A supplement never changes the licence the package declares. The
+    supplements cover `@img/sharp-libvips-linux-x64` 1.3.3 and 1.3.4, the libvips binaries that
+    `sharp` 0.35.4 and 0.35.5 load; each matches only its own version and digest, and the packager's
+    native proof builds with sharp 0.35.5. A supplement identifies and verifies licence and notice
+    material only. Source availability for copyleft native code is a separate requirement, met by a
+    corresponding-source artifact
+    ([Distributing a native package publicly](#distributing-a-native-package-publicly)).
 - **Deterministic.** The same packager version and the same built inputs produce the same archive,
  byte for byte, wherever the checkout is.

-**Drizzle, for now.** You define tables with your own copy of Drizzle, and Core runs your queries
-through the platform's Drizzle instance (see [Database access](#database-access)). Objects from two
-copies interoperate only when the copies are interchangeable, so the current implementation requires
-**exactly the Drizzle version the platform uses**: the one `@ekklesia/module-sdk` depends on. The
-package records it under `transitional`, and an installation refuses a package whose Drizzle differs.
-This is a constraint of today's implementation, not a permanent contract.
+**Database ABI v1 is the current path.** A module that declares `"database": { "abi": 1 }` keeps
+Drizzle and its exact version inside its own bundle as an implementation detail. Its package omits
+`transitional.databaseRuntime`; Core validates the module's plain schema metadata and never compares
+the bundled Drizzle version with its own. The canonical template demonstrates this path with
+`@ekklesia/module-database/drizzle`.

-`@ekklesia/module-database` now contains the module-side ABI v1 adapters that remove that coupling,
-but deployed modules cannot receive an ABI v1 executor yet. Manifest v8 and per-module runtime
-service delivery are separate later work. Until those land, the current transitional package rule
-and database service above remain authoritative; neither Module Package v1 nor the template changed
-with the adapter package.
+A manifest-v8 module that omits `database` remains on the temporary legacy facade. Only that legacy
+package records bundled Drizzle under `transitional.databaseRuntime`, and the verifier continues to
+require exact agreement with Core. The legacy facade has not been removed.

 #### Verifying a package

 `node core/dist/cli/verify-module-package.js <archive> --sha256-file <archive>.sha256`, run from an
 Ekklesia installation (`/opt/ekklesia` in the image), checks a package against that platform without
 installing it. Pass `--extract-to <new directory>` to receive the verified module directory.
-[deploy/README.md](../../deploy/README.md#installed-modules) shows the whole installation.
+[deploy/README.md](../../deploy/README.md#installed-modules) shows the supported hardened container
+invocation; use it rather than inventing mount flags. Backend verification executes package code.
+Its container is therefore the isolation boundary: general `/tmp` remains `noexec`, while a narrow,
+bounded, ephemeral verifier scratch tmpfs permits execution so native addons can load.

 The repository's boundary checks (`pnpm boundaries`) prove only source modules in a workspace. An
 installed package normally has no source, so the platform cannot check it the same way. Your
 module's own CI is where its boundary rules, its production dependencies, and its behaviour inside
 Ekklesia are proven ([ADR 0047](../architecture/decisions/0047-module-ci-harness.md)).

+#### Distributing a native package publicly
+
+Building and testing a native package needs nothing beyond the packager. **Distributing it
+publicly** does, when it redistributes native code under the GNU LGPL, the MPL, or a similar licence
+with source obligations
+([ADR 0055](../architecture/decisions/0055-corresponding-source-artifacts.md)).
+
+- **Covered dependencies.** A native dependency is covered when its declared licence, or any
+  component its reviewed supplement records inside it, carries source obligations. libvips is one:
+  it declares `LGPL-3.0-or-later`, and cairo and several Rust crates inside it are under the MPL.
+- **The policy.** A package with covered dependencies may be distributed publicly only together with
+  a corresponding-source artifact. The artifact holds the exact source, patches, build definitions,
+  and rebuild and relink instructions for those dependencies, as bytes rather than links. If the
+  artifact cannot be produced and verified, the package is not approved for public distribution.
+  This is Ekklesia's project compliance policy, not legal advice or certification. A package that
+  passes the gate meets Ekklesia's redistribution policy, and nothing more is claimed.
+- **Source recipes.** For each covered dependency version, a reviewed recipe is checked in beside
+  the supplements, under `packages/module-pack/corresponding-sources/<package>/<version>/`. It holds
+  `recipe.json` and its documents, notably `BUILDING.md`. The recipe names the exact package (name,
+  version, content digest) and the exact supplement it was prepared with. It lists every component
+  with its role (`compiled`, `build-input`, or `build-definition`), licence, licence material, and
+  relationship to the binary. Every source file and patch is recorded by origin, size, and SHA-256,
+  and every exclusion has a reason. Like supplements, recipes are reviewed data, and the mechanism
+  knows no particular library.
+
+Releasing a native package publicly takes three steps after packaging:
+
+```bash
+# 1. Acquisition: the only step that uses the network. It fetches each recorded file once into a
+#    cache keyed by SHA-256, refusing any response that differs from the recipe.
+pnpm exec ekklesia-corresponding-source acquire --package ../packages/<id>-<version>-linux-x64-glibc.tar.gz \
+  --cache ~/.cache/ekklesia/corresponding-sources
+
+# 2. Construction: offline. Every byte is verified against the recipe before anything is written.
+pnpm exec ekklesia-corresponding-source build --package ../packages/<id>-<version>-linux-x64-glibc.tar.gz \
+  --cache ~/.cache/ekklesia/corresponding-sources --out ../packages
+
+# 3. The public-distribution gate. Exit status 0 means approved.
+pnpm exec ekklesia-corresponding-source verify --package ../packages/<id>-<version>-linux-x64-glibc.tar.gz \
+  --source ../packages/<id>-<version>-linux-x64-glibc-corresponding-source.tar.gz \
+  --metadata ../packages/<id>-<version>-linux-x64-glibc.redistribution.json
+```
+
+Construction writes four sibling release artifacts beside the package. The source archive never goes
+inside the Module Package, and `THIRD_PARTY_NOTICES` is unchanged.
+
+```text
+<id>-<version>-linux-x64-glibc.tar.gz                           the Module Package (packager)
+<id>-<version>-linux-x64-glibc.tar.gz.sha256
+<id>-<version>-linux-x64-glibc-corresponding-source.tar.gz      the corresponding source
+<id>-<version>-linux-x64-glibc-corresponding-source.tar.gz.sha256
+<id>-<version>-linux-x64-glibc.redistribution.json              binary ↔ source, by digest
+<id>-<version>-linux-x64-glibc.source-notice.txt                the release notice
+```
+
+- **The source archive** is deterministic: sorted entries, fixed modes, ownership, and timestamps,
+  and no machine-specific path. The same package and recipe produce the same bytes in any directory.
+  - `corresponding-source.json` records every file with its SHA-256, and `SHA256SUMS` repeats them.
+  - Each covered dependency has its own `dependencies/<package>/<version>/` directory, with
+    `BUILDING.md`, the recipe, `PROVENANCE.md`, the supplement, and `sources/` and `patches/`.
+- **The redistribution metadata** answers "which exact source corresponds to this exact binary?"
+  from digests. It records:
+  - the package file and its SHA-256, the module identity, and the target;
+  - each covered dependency's version and content digest, and the supplement and recipe it was
+    assembled from;
+  - the source archive's file name and SHA-256, and the SHA-256 of its manifest.
+- **The release notice** must be shown alongside the binary wherever it is offered. It states that
+  the release includes third-party software under licences including the GNU LGPL and the MPL, and
+  that corresponding source and build and relink materials for the covered native dependencies are
+  in the accompanying artifact. It names that artifact by its exact file name and SHA-256.
+- **Fail-closed.** The gate refuses a package when:
+  - a covered dependency has no recipe, or a recipe or supplement does not match its exact bytes;
+  - the source archive is missing, non-canonical, or differs from its manifest;
+  - the archive holds a file the manifest does not record, or a generated file names a local path;
+  - the metadata or the notice does not name these exact files.
+
+  It also refuses bundled (not copied) copyleft code, which this mechanism does not cover. A package
+  with no covered native code is approved without an artifact.
+- **Retention.** Keep a release's source artifact for as long as its binary release is distributed
+  or supported. Never delete one automatically while the binary remains available. Never replace its
+  bytes under the same name. A correction is a new release, or an explicitly versioned compliance
+  artifact.
+
+**Available today:** a recipe for `@img/sharp-libvips-linux-x64` 1.3.4, used by sharp 0.35.5. Its
+artifact is about 200 MB: 27 library archives, 5 patches, 353 Rust crates, and the Rust standard
+library source of the recorded toolchain. Following its `BUILDING.md` rebuilds
+`libvips-cpp.so.8.18.7` from that source alone. libvips 1.3.3 (sharp 0.35.4) has a supplement but no
+recipe, so a package with it builds and tests as before but is not approved for public distribution.
+`pnpm test:corresponding-source` runs the whole proof for the native proof module: acquisition into a
+verified cache, two byte-identical builds, the gate, and sharp running from the package.
+
+**Adding a native dependency** follows the same path as libvips:
+- curate and review its supplement (ADR 0052);
+- curate and review its source recipe and `BUILDING.md`, recording every source input the
+  dependency's build fetches;
+- prove both with the native packaging tests and `pnpm test:corresponding-source`.
