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

+  imports a feature module, a surface, or an app.
-- **Modules** (`modules/*`, template at `templates/module`) are independently versioned product
+- **Modules** are independently versioned product packages. First-party modules live in **their own
-  packages. They own their own data and migrations, declare capabilities/permissions through
+  repositories** (Signage is `Zayin/Signage`), build against the published `@ekklesia/*` packages
-  `@ekklesia/contracts` and `@ekklesia/module-sdk`, and must never import Core, another module, or a
+  (ADR 0053), and reach an installation as a Module Package (ADR 0049) installed into module storage
-  surface directly. Per ADR 0021 a module owns its UI; manifest v7 permits independently optional
+  outside the image (ADR 0048). No module source lives in this repository; `templates/module` is the
-  primary and full-viewport display artifacts, authored in React against the same role-neutral
+  example, and `modules/` is only an optional, ignored local installed-modules directory. A module owns

 - **Surfaces** (`surfaces/*`) own the containing application shell, navigation, and every

+  presentation concern a module does not. The shell **hosts** module UI through the generic loader;
-  or module internals directly.
+  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.

+# 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
+Restart=always
+RestartSec=5
+
+[Install]
+WantedBy=graphical-session.target
+```
+
+```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.
+- [ ] Paired and named; assigned in Signage.
+- [ ] Unplug the network for a minute: content keeps playing, then the note clears on reconnect.
+- [ ] Reboot: the screen comes back paired without anyone touching it.

+# 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.
