well — identity, sessions, SSO, OAuth2, permission checks — is delegated to **Ory**
sidecar services rather than reinvented.
"Simple" here is about the **whole architecture staying simple** — not just at the
start, but after you've dropped in 240 plugins and run it hard in production. The
shape doesn't change as it grows: every plugin is the same self-contained folder,
the hot path is the same I/O-free JWT check, and there's no app database to scale
or migrate.
## Who this is for
**Experienced developers building back-office, admin, and dashboard products**
for their own use or for a client. You know your way around HTTP, Docker, and an
identity provider, and you'd rather assemble pages from solid building blocks than
fight a framework or hand-roll auth for the tenth time. Plainpages hands you the
boring-but-hard parts (auth, authz, menu, design system, plugin host) and stays out
of the way of your domain logic. It does not try to be a no-code tool or hide its
moving parts: if "Ory is down ⇒ no logins" (see [Auth](#auth-sessions--permissions-planned))
reads as an obvious consequence rather than a surprise, you're the audience.
## Project goals
Beyond the priorities above, Plainpages deliberately targets **low-end systems, odd
hardware, and low-bandwidth environments** — a tablet on a factory floor, an old
thin client at a reception desk, a remote site on a flaky link. That's *why* the
baseline is standards-compliant, boring **HTML + CSS** with zero JavaScript: it
loads fast, degrades gracefully, and works on whatever browser the site already
has. Where a modern **CSS** feature removes the need to ship JavaScript (theme
switching, popovers, disclosure), we'll happily use it — the trade we avoid is
shipping a client-side runtime, not using the platform.

## The MVP — "clone, one command, hack on a plugin" _(planned)_
The bar for a first usable release: **clone the repo, run one command, and you have
a working register/login and can start building your own plugin** — no manual key
generation, no hand-edited Ory config, no separate database setup. One command
brings up the whole stack (web + Ory + Postgres), generates signing keys and seeds
an admin on first boot, and drops you at a login screen. From there you copy the
example plugin folder and you're writing your own page. That moment — clone → one
command → login → your plugin renders — *is* the MVP. SSO and the OAuth2-provider
role (Hydra) come after; they aren't required to start.

app stays stateless; "stay signed in" = re-mint the JWT on a short TTL, the one
moment authz is recomputed from Keto.
#### Two trade-offs — both deliberate
This design buys an I/O-free hot path that scales to **tens of thousands of
concurrent users** on modest hardware. In return:
- **Role changes lag by up to one TTL (~10m).** Because gating reads the JWT, not
Keto, a granted or revoked role only takes effect when the token is next minted
(re-login or TTL refresh). For an admin tool this is intentional: the alternative
is a Keto call on every request, which we explicitly traded away. If a deployment
needs instant revoke, the optional revocation denylist (roadmap) closes the gap
for the security-critical cases without putting Keto back on the hot path.
- **Ory is on the critical path for sign-in.** If Kratos is down, no one can log
in; if it stays down past the TTL, existing sessions can't refresh and the UI
goes dark. This is the direct consequence of being stateless and delegating
identity — there is no local fallback, by design. Run Ory with the same
availability you'd give any auth provider.

Write it down as the authoritative reference: the full manifest shape; the `RequestContext` handed to handlers and what's guaranteed stable; **contract versioning** (a `apiVersion`/`engines`-style field so a plugin declares the host it targets, and the host refuses or warns on mismatch); **conflict rules** (two plugins claiming the same `basePath`, nav slot, or `permission` name → defined, loud resolution, not last-write-wins); the **local dev/test story** (how an author runs + tests one plugin in isolation against the host).
