 - [x] Add an e2e test for the admin plugin's OAuth2-clients (Hydra) screen. The full-flow e2e suite runs without Hydra (compose.full.yml), so /admin/clients register/detail/delete is only unit-covered (src/http/app.test.ts); wire Hydra into an e2e stack and drive the screen in the browser. (compose.full.yml now includes Hydra (`serve all --dev`) and full-flow.spec.ts drives /admin/clients register → one-time secret → list → detail → delete in the browser; documented in README → Testing.)
 - [x] Build and publish docker image as CI/CD. (Duplicate of the CI/CD items above: `ci.yml` builds and pushes `gitea.larvit.se/larvit/plainpages:<commit hash>` behind the green gate, `release.yml` re-tags it to semver and syncs those tags to Docker Hub.)
 - [x] The human developer understands the security model in the auth in this project. (Two README sections. [Users, groups & permissions](README.md#users-groups--permissions) carries the weight: the entity model, a worked graph, a per-route can/cannot walkthrough, and the trap that a per-row grant never widens a coarse gate — placed before Building plugins because a manifest's `permission:` gate is unreadable without it. [Security model](README.md#security-model) is deliberately short, only the facts a deployment gets wrong without them: the private network as the *only* guard on the Ory APIs, signed-not-encrypted claims, the 30-day Kratos session behind the ~10m JWT, and non-instant offboarding. The first attempt answered the *threat* model instead — a 12-row attack/defense table — which was the wrong question and mostly restated code readable at its source; cut. Also corrected the hardening checklist: `REQUIRE_SECURE_SECRETS` guards only `CSRF_SECRET`, so the committed Kratos/Hydra/Postgres/demo-admin secrets are now listed in "What you must supply". The mandatory-`exp` guard gained a test in `src/auth/jwt-middleware.test.ts`.)
- [ ] Add i18n support.
+- [x] Add i18n support. (Catalogs are TS modules per locale — `src/i18n/locales/<tag>.ts` for the host, `plugins/<id>/i18n/<tag>.ts` for a plugin, looked up plugin-first then core; en-US + sv-SE ship. A request is served by `?locale=sv-SE` → `Accept-Language` → `en-US`, exact on a full tag but a lone language takes the first regional catalog; no cookie — when the URL asked, the host carries `?locale` onto the links it renders and `ctx.localeHref()` does it for a plugin's. `ctx.t(key, vars)` plus `t`/`locale`/`locales`/`localeHref`/`dir` merged into every view (any include depth); `{{var}}` interpolation, plurals via `Intl.PluralRules`, an unknown key renders as itself — which is what makes a nav label either a key or plain text. Every catalog is checked against its set's en-US at boot (keys, kind, plural categories) and a mismatch stops startup. Kratos' own flow text is mapped by its numeric id (only ids verified against the live stack; its generic trait-label id is deliberately unmapped, field labels key on the input name instead). Zero-JS language picker in the shell + the auth/consent pages, `<html lang dir>` from the locale. Core, both example plugins and their views translated; unit tests + `e2e-tests/language.spec.ts` in the visual gate; documented in README → Languages, decisions in AGENTS.md.)
 - [x] Settle the identity-vs-user vocabulary. (Plainpages says **user** everywhere — Keto namespace `User`, subjects `user:<kratos-id>`, `ctx.user`. Ory calls the record an "identity", but its own docs say it uses that term interchangeably with "users"/"accounts", so this is house style rather than a renamed concept, and "user" is the word readers know (Nielsen heuristic #2). README → Auth carries one note recording the mapping; the only place Ory's spelling survives is the `Identity` DTO in `src/auth/kratos-admin.ts`, which mirrors the Kratos wire shape. Recorded in AGENTS.md.)
 - [ ] Decide whether the single generic Keto `Resource` namespace should become per-domain namespaces (`Shift`, `Document`, …), as Ory's own examples model it. One global `Resource` bucket is the project's own "no catch-all names" rule (`utils`, `helpers`, `misc`) applied to namespaces. Raised 2026-08-03; a design question, not a naming one.
 - [ ] Decide (once) whether the CSRF token staying unbound to `sub`/session is accepted. `src/auth/csrf.ts` signs `<nonce>.<HMAC(secret, nonce)>` with no session binding, so any validly-signed token passes for any user — an attacker who can write cookies on the origin (a sibling subdomain, or a plaintext hop with `SECURE_COOKIES=false`) can fix a token they know. Standard for unbound signed double-submit and plausibly fine behind `SameSite=Lax` + HSTS. Accepted ⇒ record it in AGENTS.md → "Deliberate architectural deviations" and in README → Security model under "Not guaranteed"; not accepted ⇒ bind the nonce to `sub` (small change). Raised by review 2026-08-02; left undecided because it is a maintainer call, and an undocumented exception reads as a bug to the next reviewer.
