 **Keto ships no entities of its own.** Its entire model is one primitive —
 `namespace:object#relation@subject` — so the four namespaces above are *ours*, declared in
 `ory/keto/namespaces.keto.ts`; Keto only supplies the machinery that resolves them (including
 transitively, through nested groups). `Identity` is named to match Kratos, which owns that
 record. `Group`, `Role` and `Resource` have no upstream counterpart to match, so they use the
 ordinary words.

 - [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. (README → Auth → [Security model](README.md#security-model): trust boundaries — browser untrusted, JWT untrusted until verified, the private network as the *only* guard on the unauthenticated Ory admin APIs, plugins trusted and unsandboxed, row rules upstream — plus a threat→defense table, the fail-closed rule, and pointers to the limits that are deliberately not guaranteed. Signed-not-encrypted is called out so nothing secret lands in a claim, and the JWT's ~10m TTL is separated from the 30-day Kratos session that re-mints it. Every row of the threat table is enforced by a test — the mandatory-`exp` guard was the one gap, now asserted in `src/auth/jwt-middleware.test.ts`; the trust-boundary bullets are not testable claims. Review also corrected the hardening checklist — `REQUIRE_SECURE_SECRETS` guards only `CSRF_SECRET`, so the committed Kratos/Hydra/Postgres dev secrets are now listed in "What you must supply". Follow-up: the *threat* model turned out not to be the part that was unclear — the **authorization** model was. README gained a top-level [Users, groups & roles](README.md#users-groups--roles) section (entity table, worked graph, per-route can/cannot walkthrough, the "a per-row grant never widens a coarse gate" trap), placed before Building plugins because a manifest's `role:` gate is unreadable without it.)
 - [ ] Add i18n support.
- [ ] Decide whether the Keto `User` namespace should follow Kratos and become `Identity`. Kratos never says "user" — it is `/admin/identities`, `identity.traits`, `session.identity` — but our OPL declares `class User` with subjects `user:<kratos-identity-id>`, and the code already mixes both (`login.ts` passes `identityId`, `context.ts` exports `User`). Aligning means renaming the namespace *and* the `user:` subject prefix, which rewrites every relation tuple in Keto's Postgres — a data migration, not a code change. Raised 2026-08-03 while renaming the coarse gate to `role`; deliberately left out of that change because it is a different and much heavier class of edit.
+- [x] Follow Kratos and rename the Keto `User` namespace to `Identity`. (OPL `class Identity`, subjects `identity:<kratos-id>`, and the session type `User` → `SessionIdentity` with `ctx.user` → `ctx.identity`. No migration was needed after all: `keto-migrate` runs Keto's *own* bundled schema migrations and our tuples are runtime data written by `bootstrap.ts` and the admin plugin — with zero installations, `docker compose down -v` is the whole story. The name collided with the existing `Identity` DTO that `#plugin-api` re-exports from `kratos-admin.ts` — that one is the full Kratos record (traits, state, addresses) and kept the plain name; ours is the JWT projection `{ id, email, roles }`, hence `SessionIdentity`. The presentation layer deliberately still says "user" — `ShellUser`, `chrome.user`, the EJS `user` locals — because that is the avatar/profile view-model, not the identity entity.)
 - [ ] 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.
