Plainpages — implementation TODO

Build order is top → bottom; each phase is roughly independent and testable. Conventions: write tests first (node --test for units, Playwright for E2E), tear down test containers after runs, keep deps minimal, pin all versions, run everything via Docker.

0. Housekeeping / primitives

• Decide JWT verify approach: node:crypto (RS256/ES256 via createPublicKey({format:"jwk"})) vs add jose — justify if adding.
• Cookie helpers: parse Cookie header, build Set-Cookie (HttpOnly, Secure, SameSite).
• Request context type threaded to handlers: { req, res, url, params, query, user|null, roles }.
• Error templates: add 403 + 500 (404 exists).
• Config/env loader: Ory endpoints, cookie/CSRF secret, JWKS location, ports.

1. Building blocks — extract from html-css-foundation/ (no Ory needed; render mock data)

• Move styles.css + auth.css into public/css/; reconcile with existing style.css.
• Lucide icon sprite → views/partials/icons.ejs.
• App-shell partial (sidebar + topbar + content slot).
• Nav-tree partial — recursive, header/leaf × clickable/static, counts, aria-current.
• Filter-bar partial — GET form (search, segmented, selects, chips, daterange, applied pills).
• Data-table partial — sortable headers, row-select, badges, kebab row actions.
• Pagination partial — rows-per-page + page numbers, query-param driven.
• Form-field partials (input/label/hint/error) + auth-card partial.
• Menu/popover + theme-switch partials (pure CSS details/summary).
• Helper composeNav(fragments, override, roles) → merged, permission-filtered tree.
• Helper parseListQuery(url) → { q, filters, sort, page, pageSize }.
• Helper paginate(total, page, pageSize) → page model.
• Unit tests for all helpers (first).
• Replace placeholder index with the app-shell dashboard.

2. Plugin host

• definePlugin() + manifest types: id, basePath, nav[], routes[] {method, path, permission?, handler}.
• Discovery: scan plugins/, import each plugin.ts default export, validate.
• Router: match method+path under basePath, resolve path params, run permission gate, call handler with context.
• Per-plugin view resolver (plugins/<id>/views/*.ejs).
• Per-plugin static serving: plugins/<id>/public/ → /public/<id>/.
• config/menu.ts central override: reorder/rename/hide/group + branding (app name, logo, default theme).
• Wire branding into the app shell.
• Tests: discovery, routing, param matching, permission gate, nav merge + filter.

3. Ory stack — compose + config

• postgres service (pinned tag); separate DB/schema per Kratos/Keto/Hydra.
• kratos service (pinned) + migrate; identity schema (traits: email, name).
• Kratos self-service flows (login, registration, recovery, verification, settings) → return URLs at our themed pages.
• Kratos OIDC/SSO providers (Google/Microsoft/SAML) config (placeholders + secrets via env).
• Kratos session settings (cookie name, lifespan, sliding refresh).
• Kratos tokenizer template plainpages: claims { sub, email, roles }, ttl ≈ 10m, jwks_url signer, claims_mapper_url (Jsonnet reading metadata_admin.roles).
• Generate + mount the JWT signing JWKS; document key rotation.
• keto service (pinned) + migrate; namespaces in OPL (role, group, resource permissions).
• hydra service (pinned) + migrate; issuer + login/consent URLs → our app.
• Split dev (compose.override.yml) vs prod (compose.yml) wiring; health checks + depends_on ordering.

4. Auth — identity, session JWT, guards

• Kratos public client (fetch): init/get/submit flows, whoami, whoami?tokenize_as=plainpages.
• Kratos admin client (fetch): identity CRUD + metadata_admin update.
• Keto client (fetch): check, list/expand relations, write/delete tuples.
• Render Kratos flows: fetch flow → render fields against our themed pages → POST to flow.ui.action (Kratos handles its CSRF), map field errors/messages.
• SSO buttons → Kratos OIDC flows.
• Login completion: read roles from Keto → write metadata_admin projection → tokenize → set JWT cookie.
• JWT middleware: verify signature via cached JWKS, validate exp/iss/aud (+clock skew), build context (user, roles).
• JWKS fetch + cache + rotation handling.
• Guards: requireSession (validate JWT), can(role) (claim, in-process), check(relation, object) (live Keto).
• Session re-mint on TTL expiry (re-read roles from Keto).
• Logout: revoke Kratos session + clear cookie.
• Secure cookie flags; CSRF for our own POST forms.
• Tests: JWT verify (valid/expired/bad-sig), guard behavior, login→projection→tokenize flow (Ory mocked).

5. Built-in admin screens (writes go only to Keto/Kratos)

• Users: list (Kratos identities) with filter/sort/pagination; create/edit/deactivate/delete; trigger recovery.
• Groups: Keto subject sets — list/create/delete + membership management.
• Roles & permissions: Keto relations — assign roles to users/groups; "effective access" view via Keto expand.
• Wire into the menu (admin section, permission-gated).
• Tests: CRUD flows (Ory mocked) + permission gating.

6. Hydra — OAuth2/OIDC provider (can ship after the rest)

• Login-challenge handler: authenticate via Kratos session, accept/reject.
• Consent-challenge handler: show / auto-accept first-party, grant scopes, accept/reject.
• OAuth2 client registration (admin UI or CLI).
• Tests: authorization-code login+consent happy path; token + refresh.

7. Example plugin (reference)

• Reference plugin (e.g. people directory or scheduling): list page fetching upstream data, a form that forwards writes upstream, permission-gated nav.
• Verify the full plugin contract end-to-end against the README.

8. Testing & CI

• node --test units across helpers / router / nav / auth (tests-first throughout).
• Playwright full E2E: login (password + mocked SSO), menu filtering by role, users/groups/permissions CRUD, a plugin page, logout.
• E2E harness: bring up the full compose stack, seed Keto roles + a test identity, tear down after.
• Typecheck + tests green in Docker (docker compose run --rm web …).

9. Production, security, ops

• compose.yml prod: Ory + Postgres, secrets via env, no source mount.
• Security headers; secure/HttpOnly/SameSite cookies; CSRF; clock-skew tolerance.
• Optional revocation denylist for instant role/session revoke.
• Structured logging / basic observability. use @larvit/log for OTLP compability - but add subtasks and stuff for supporting incoming trace id etc from a reverse-proxy etc.
• JWT signing-key rotation runbook.
• Refresh README Layout + drop _(planned)_ markers as pieces land.
