+# Changelog
+
+One line per change, grouped by the release that shipped it. Newest
+first. A release is a Cargo.toml bump plus a `v<version>` tag; the
+content repos pin the tag they run (see the end of this file).
+
+## 0.5.3 (2026-09-29)
+
+- A way down the tree from every page: an arrow fixed at the left edge, half-way up, and the same link in words at the foot ("Tilbake til starten", "Back to “What came in?”"). It goes to the nearest page below the current one that the visitor may open, taking the path apart a segment at a time, and to the front door when none is; the front door has none. Content no longer needs a "back" alternative, and a visitor who went up a branch that turned out not to apply is never stranded.
+
+## 0.5.2 (2026-09-28)
+
+- The rate limiter answered 500 to any request that arrived without `X-Forwarded-For`. It reads the caller from that header or `X-Real-IP` and falls back to the socket, and 0.5.0 served the app without connect info, so there was no socket to fall back to and no key to rate-limit by. Through Caddy every request carries the header and the site was fine; a health check on localhost got a 500, which is how the first deploy of 0.5.1 failed.
+
+## 0.5.1 (2026-09-28)
+
+- A `self_transition` that names no `from` means the bucket's own initial state, not the word `open`. 0.5.0 read the literal, which is only right for a bucket whose records start there: redoal's watchers arrive at `pending` and confirm themselves into `open`, so the rule compiled as `open -> open` and the confirm link in the mail could never match. Wrong the same way before 0.5.0, and now visible because the lint checks the edge exists.
+
+## 0.5.0 (2026-09-28)
+
+- Sessions live in NATS KV (`src/sessions.rs`), not in memory. Every restart used to sign out every desk on the site being deployed; they now survive it, in the JetStream that is already under everything else - no new service and no new store to run. The bucket's `max_age` collects what nobody returns for, and a record's own expiry is what answers a load.
+- Fixed: the JetStream integration test asserted a record's projected state was one a desk move had never written to it, so it failed whenever it actually ran. `test.yml` has been red since 0.3.47 while `publish.yml` stayed green, which is how 0.4.0 shipped past it.
+- A file can come back out. `GET /attachment/{bucket}/{record}/{field}` streams what a `type: file` field stored, reading the object key out of the record rather than taking one from the caller - so a file is only reachable through a record somebody may see, and a key that leaks off a desk is a link to nothing. Before this, uploads were one-way: a desk showed the key as a string and there was no way to open it.
+- Rate limiting, per caller IP, outside everything else: a burst of 30 refilled one every two seconds (`PORTAL_RATE_BURST`, `PORTAL_RATE_SECONDS`; either 0 turns it off). A form-filling visitor never reaches it; a script does. There was none at all before.
+- `/upload` asks the policy, like every other way in. It asked nothing: any caller who could reach the host could put 20 MB in the bucket, as often as they liked, and a site whose forms are public is a site whose upload route is public. It now takes the `question` and `alternative` the file is being attached to, refuses a page that declares no `type: file` field or an alternative that is closed, and asks `Submit` on that page - the same question the submission itself will ask - before a byte is written. Latent until an instance had storage configured; the first one now does.
+- A submitter stays in dialogue with their case for as long as it runs. `self_transition` takes `from: [state, ...]`, and the access policy compiles one rule per state named; it defaulted to the initial state alone and was written that way in the compiler, so an applicant written to for a missing drawing could not send it, and nobody could withdraw once anything had happened. Omitted, it still means the initial state alone.
+- A record can belong to another record. `type: record` with `of: <bucket>` stores the parent's id, which arrives on the link rather than being typed; a submission naming a record that is not there is refused. The other half is `where: { field, equals }` on a Kv resource, so an application's page can list the objections that name it.
+- A public view need not publish the whole bucket. `states: [...]` on a Kv resource shows only those, for one record as well as a listing - a register that is public by law is public about what was decided, not about what was withdrawn. The desk over the same bucket is a different spec and still sees all of it.
+- A state can grant a group: `grants: <group>` beside its `event`, so an approval that means membership does not also need somebody to remember to invite them afterwards. The lint requires the forms that fill such a bucket to collect a required name and email, because by the time a desk presses approve there is nobody left to ask.
+- A state can be moved by a clock: `after: { days, to }`, swept hourly, measured from the record's last move (`src/deadlines.rs`). A deadline may only do what a person could have done - `after.to` is held to the same declared edge as a desk button - and the move fires the same mail and publishes the same event, stamped `deadline`.
+- Documentation moved out of the README into `docs/`: architecture, content reference, state machines, access, operations.
+- A page says nothing until it has something to say. The Suspense fallback on a question was the whole served page - no header, no wordmark - so the first and only thing a visitor or a crawler read was the word "loading…", which is true and is not about them. It now holds the space and stays quiet, with `aria-busy` for a reader that would otherwise find an empty document.
+- Gone: the `gitea_org_repos` resource kind, which no site ever named. `gitea_starred` and `gitea_releases` stay.
+
+## 0.4.0 (2026-09-24)
+
+- A field can be a place: `type: location` puts a pin on a map and stores `{lat, lon, zoom}`; a record holding one renders as a still map on its desk and in any resource card.
+- A question can be about a place: `place: { lat, lon, zoom, name }` is the counterpart to `event:` - event makes a page an occasion with a time, place makes it somewhere, draws the map under the question, and opens any location field on that page there instead of on the globe.
+- Maps are served from this origin. Portal fetches every tile and every still itself (`src/maps.rs`, MapLibre vendored), so a page with a map on it makes no third-party request, needs no consent banner, and the `MAPBOX_TOKEN` never leaves the server. Unset, the feature is simply off.
+- A reply to a case mail becomes a note on its record: whatever reads the mailbox publishes on `portal.mail.received` and portal appends the note, after checking the record exists and the sender is the address the record itself holds. A note never moves a case.
+
+## 0.3.47 (2026-09-24)
+
+- iris: needs.yaml takes `stage_words`, each state in the site's own words, carried into the simulation model for the trainer's desk score. No change to portal itself.
+
+## 0.3.46 (2026-09-23)
+
+- An invite first looks the email up in Kanidm (`/v1/raw/search` on `mail`, when the service account may read people: `idm_people_pii_read`) and only adds an existing account, under whatever username, to the group; no second account, no reset link.
+
+## 0.3.45 (2026-09-23)
+
+- A mail stream that cannot be created at boot (subjects owned by an older stream) is a warning, not a failed start; 0.3.44 took the kasse sites down for two minutes on the rename.
+
+## 0.3.44 (2026-09-23)
+
+- The mail stream is named `mail` (was `WORMHOLE`); gdo 0.1.2 matches. Delete the old stream on each NATS after upgrading both.
+
+## 0.3.43 (2026-09-23)
+
+- Mail is content: `mail: { to, subject, body }` on a state in aggregates.yaml sends when a record enters that state (`to: submitter` or one address; `{field}`, `{site}`, `{chain}`, `{email}` in the templates), and an invite mails its one-time link built in; `site.yaml` gains `mail: { from, reply_to, invite }`. Portal renders and publishes on `portal.mail.send` in the `WORMHOLE` stream; uhhm/gdo delivers. The lint requires a required `email` field on every form recording into a bucket that mails the submitter.
+
+## 0.3.42 (2026-09-23)
+
+- people: the Kanidm person lookup reads the body, since Kanidm 1.11 answers a missing person with 200 and `null` rather than 404; before this every invite skipped account creation and failed on the group step
+
+## 0.3.41 (2026-09-23)
+
+- publish: the iris release step retries on a fresh clone when its push loses a race against a push to iris main (the v0.3.40 tag never published)
+- iris: `check --access` prints the access matrix, and every check validates the compiled policy against the schema
+
+## 0.3.40 (2026-09-23)
+
+- One access policy, compiled from content into Cedar on every load (`src/access.rs`): pages, resource reads, desk transitions, self transitions and the automation endpoint all decide through it; decisions carry rule ids, refusals and mutations publish on `portal.access.decided`, and `portal.access.<site>.may` answers the same question for other apps over NATS
+- `invite: {group}` on an alternative onboards a person into Kanidm from a desk (`src/people.rs`, `KANIDM_API_TOKEN`), recording the one-time credential link in `portal_invites` and on `portal.people.invited`
+
+## 0.3.39 (2026-09-23)
+
+- publish: releases the matching uhhm/iris by proxy - re-pins, builds, tests and tags it as this version (needs the `IRIS_PUSH_USER` variable and `IRIS_PUSH_TOKEN` secret); iris carries portal's version number from here on
+
+## 0.3.38 (2026-09-22)
+
+- publish: the iris build step gets a writable cargo home; the v0.3.37 tag never published
+
+## 0.3.37 (2026-09-22)
+
+- The lint moves to its own repo, uhhm/iris: `question_lint` becomes `iris check`, `needs_replay` becomes `iris replay`; the tarball ships `iris` (pinned in publish.yml) instead of `question_lint`; the needs module and local loaders leave portal
+
+## 0.3.36 (2026-09-22)
+
+- Question nav: a followup is offered only once earned - the verified chain answered the alternative leading there, or a link that records nothing leads on from an earned page. Standing on a page no longer unlocks the pages behind its forms; the chain index now records which alternative was answered
+- One bounded HTTP client for every server-side fetch: 20 s budget, size caps per kind of fetch (`src/http.rs`)
+- Uploads are refused past 20 MB while streaming, and the route body limit that had capped them at axum's 2 MB default is raised to match
+- `tests/jetstream.rs`: the store, the event log and the projection tested against a real JetStream (CI starts a throwaway one)
+- `content` split into `gitea`, `validate`, `markdown`, `handlers`; every path still `content::x`
+- This changelog, and the table of what each site runs
+- Business needs as a checkable spec: needs.yaml + question_lint pass
+- needs: `success` states and a resolved simulation model
+- needs: `stages` - every stage the business named must be a state
+- needs_replay: make simulated cases real aggregates, report buckets by state
+- needs: also_moved_by - a need carried by more than one group's desk

+- Attended-bucket lint rule; app-lifetime resources fix first-nav corruption
+
+## 0.2.2 (2026-08-24)
+
+- One app-level Title fed by a shared site resource
+
+## 0.2.1 (2026-08-24)
+
+- Docs: routing bullet + design doc marked implemented
+- Revalidating cache on app assets; site title survives SPA navigation
+
+## 0.2.0 (2026-08-24)
+
+- Initial commit: content-driven onboarding portal
+- Load content from Gitea directly, drop the local clone; add deploy workflow
+- Share sccache between manual dev builds and CI
+- Give CI its own SCCACHE_SERVER_PORT
+- Erase view types at every list/component boundary, not just leaves
+- Redirect cargo-leptos's tool cache out of act-runner-bare's StateDirectory
+- Fix Ship release: site-root is project-relative, not CARGO_TARGET_DIR
+- Drop sudo from the deploy workflow - NoNewPrivileges blocks it outright
+- Caddy snippet: use multi-line log block
+- Fix static asset 404s and build-time SITE_NAME
+- Hot-reload content on a NATS trigger instead of requiring a restart
+- Add prosekit rich-text field, Gitea repo embeds, automation KV read endpoint; fix apex/www session-cookie mismatch on /auth/callback
+- Fix prosekit-editor.js: remove bare CSS imports that aborted the whole module
+- Redirect back to the originating page after sign-in, not always /
+- Fix hero-canvas navigation race; style the prosekit editor and add a toolbar
+- yes.js: guard against the canvas not being in the DOM yet
+- Fix get_resource/transition_answer: scope feature lookup to its own alternative
+- Add self-service transitions, authorized by item possession not group membership
+- Event-sourced applicant/subscriber/project aggregates, generalized resources
+- deploy.yml: write GITEA_API_TOKEN for the new GiteaStarred/OrgRepos resource sources
+- Cargo.toml: disambiguate bin-target for cargo-leptos
+- Add manually-triggered backfill workflow, no terminal/sudo needed
+- Trigger redeploy to pick up PORTAL_GITEA_API_TOKEN secret
+- Render generic resource lists as cards, not raw JSON dump
+- Fix recursion-limit build failure in the new item-card renderer
+- Resource-backed multi/single-select requirement
+- Add Organization aggregate (client-as-status), wired but inert
+- Fix favicon (real icon, not an unrelated orange circle) + stack encouragements with the submit button
+- Fix bucket-404 on empty resources, redesign review actions as select-then-confirm, CSS polish
+- Inline encouragements with the submit button, vertically centered
+- Use the real institutional logo for the header wordmark, not plain text
+- Use the actual UHHM-letters wordmark, not the institutional mark
+- Responsive base font size via svmin, not fixed 17px
+- Add plain-unit fallbacks for svmin/svh in case of unsupported engines
+- Size the YES canvas from its container, not window.innerHeight
+- Debounce the YES canvas resize handler and skip no-op resizes
+- Revert canvas sizing to window.innerWidth/innerHeight, gate resize on width change
+- Stop blocking native scroll on the YES canvas's touch handlers
+- Quicksand: font-display optional, not swap, to stop the text-jump on scroll
+- Use lvh/lvmin, not svh/svmin - svh was the wrong end of the viewport
+- Update style/main.css
+- Update style/main.css
+- YES canvas: size off its own container rect, not window.innerHeight
+- yes.js: freeze .hero-yes's height via inline style, don't trust svh alone
+- add responsive container width
+- deploy.yml: build and publish question_lint alongside the app binary
+- Make aggregate state graphs content-driven, not compiled Rust
+- One shared, content-labeled Confirm button per alternative instead of one per row
+- get_resource/get_requirement_options: #[server(default)] on params
+- Add optional Alternative.image and Feature.color/icon for richer layouts
+- Drop the feature list's left-padding
+- Drop question-report entirely, obfuscate the mailto link instead
+- Transition.from: state graphs deeper than one decision
+- Alternative.images: array of urls, rendered as a Swiper card deck
+- Reseed lost event history from the KV projection on transition
+- Lighten the comment load
+- Validate action targets; format timestamps client-side; clippy cleanup
+- Question nav + gateway alternatives
+- Responsible note under the title; followup pages out of the nav until a chain exists
+- README: what the engine provides
+- Feature icons: masked span painted by currentColor, not <img>
+- Responsible note: one line, same hue and size as the hero description
+- Responsible note as <small>: meta information, dimmer than the description
+- Responsible note back to the footer, above the question nav
+- Bound inputs: a field that loads its value from a sibling-parameterized resource
+- add some more width to our alternatives
+- Accent to a dusty press-cyan, a muted echo of the canvas's cyan ink
+- Editor type in rem: prosekit's px typography ignored the responsive root
+- Ban px from stylesheets: every length rem/em off the responsive root
+- No translucent input chrome: solid ink-dim placeholders and embed meta
+- Editor type scales for real: drop prosekit typography.css, fix selectors
+- Stable server fn endpoints: open tabs survive deploys
+- Drop stray local tool temp file, ignore .claude/
+- Noise-driven YES, sticky hero with frosted cards, full light theme
+- increase translucency of laternative cards
+- Showcase jq test tracks Gitea repo shape and website-first links
+- Gesture input type, redoal-relay client, gitea_releases, content-driven branding
+- Echo thumbnails fade in via timeout, not rAF
+- Trigger deploy: redoal OAuth2 credentials now configured
+- Deploy becomes publish: portal ships as a versioned release artifact
+- Semver releases cut with cargo-release; publish on v* tags only
+- Docs: release/rollout flow after the instance-ownership refactor
+- README: frame portal as a generic multi-site question engine
+- Design doc: filesystem routes, sections, dynamic segments
+- Filesystem routes, sections, dynamic segments; instant YES hero
+
+
+## What each site runs
+
+Read from the hosts on 2026-09-28; a rollout is a pin bump in the
+site's content repo (`PORTAL_RELEASE` in its `deploy.yml`) - on both
+hosts now, since kasse's runner deploys its own instances.
+
+| Site | Host | Instance | Version |
+|---|---|---|---|
+| uhhm.no | ergo | `app@uhhm-portal` | v0.5.2 |
+| redoal.com | ergo | `app@redoal-portal` | v0.5.2 |
+| westra.klingenbergbygg.no | kasse | `app@westra-portal` | v0.5.2 |

+hosts the content, NATS JetStream stores the events and projections,
+Kanidm provides identity, and anything downstream — automations,
+newsletters, onboarding — subscribes to the answer stream.

-## What the engine provides
+## Documentation

- **Content-driven pages** (`src/content.rs`, `src/app.rs`): YAML
-  loaded from Gitea at boot and hot-swapped on a NATS reload signal;
-  a bad push keeps the last-good content serving. The `questions/`
-  tree IS the router — file paths become URLs, `_section.yaml`
-  applies criteria to a whole directory, `[name].yaml` pages serve
-  any `/dir/<value>` with the segment fed into resource keys, and
-  `requires_chain` gates a page on verifiable answer provenance next
-  to `qualifies`' Kanidm-group identity gate (see
-  `docs/design/filesystem-routes.md`).
- **Gesture and voice fields** (`gesture.js`, `voice.js`): a stroke
-  becomes a redoal gesture key through a relay (ADR-0013/0015 in the
-  redoal repo) - the input shows the key's own decode under the
-  stroke, who is at a similar shape now, and *places* with recordings
-  the visitor can pick to make that key theirs; a voice field records
-  in the browser and leaves the audio at a key. Actions may be
-  templated from the answer (`/shape/{curve.key}`) onto dynamic
-  pages, whose URL segment also fills `value: "{key}"` presets and
-  `url` resource sources; resource items with an https `audio` field
-  render a player.
- **Announced pages** (`src/announce.rs`): a question with an
-  `event: {starts, duration, place}` window is announced in the
-  header (not the footer nav) while the window is open, becomes a
-  followup when it closes, and its record in the runtime-owned
-  `portal_events` bucket moves to `awaiting_summary` - a "post what
-  happened" task any review desk can read, published on NATS like a
-  decision. A one-minute sweeper keeps it all idempotent.
- **State machines as content** (`src/aggregates/`): `aggregates.yaml`
-  declares each bucket's states and legal transitions; the engine
-  replays a record's event history and refuses undeclared moves, with
-  optimistic concurrency (CAS on the event log's sequence) against
-  racing decisions. An empty history reseeds from the KV projection,
-  so wiping the event stream strands nothing.
- **Durable events + projections** (`src/events/`, `src/answers.rs`):
-  every submission and decision appends to a JetStream event log and
-  projects into a NATS KV bucket pages read back; every one also
-  publishes on `portal.answers.submitted` for automations (n8n) to
-  react to.
- **Answer chains** (`src/chain.rs`): each submission hashes its
-  parent(s), so a visitor's path through the questions is a verifiable
-  lineage; `?chain=` links carry it, and self-service transitions
-  (unsubscribe) authorize by holding one.
- **Live resources** (`src/resource.rs`): content can pull a KV
-  bucket, Gitea starred/org repos/releases, or any public JSON URL
-  (SSRF fail-closed), reshaped by a content-declared `jq` filter.
- **Input kinds as content**: a requirement's `type:` picks the
-  widget — plain fields, a rich-text editor, or a `gesture` drawing
-  canvas that can connect to a redoal relay so similar strokes echo
-  between visitors live. Submitted values are arbitrary JSON; the
-  engine records what the widget produced.
- **Review desks**: any Kv resource with `transitions` renders rows
-  with per-state action buttons and one shared confirm per
-  alternative — owners walk records through their graphs without
-  bespoke UI per bucket.
+Everything is under [`docs/`](docs/README.md):

-## Binaries
-
- `portal` — the server (Leptos SSR + hydrate, Axum underneath).
- `question_lint` — headless content validation, shipped inside every
-  release artifact so each content repo's CI lints with the exact
-  portal version its instance runs; also works offline:
-  `question_lint --path <dir>`.
+- [Architecture](docs/architecture.md) — what the engine is made of.
+- [Content reference](docs/content-reference.md) — every key a content
+  repo may write.
+- [State machines](docs/state-machines.md) — `aggregates.yaml`.
+- [Access](docs/access.md) — the policy compiled from content.
+- [Operations](docs/operations.md) — releasing, deploying, adding a site.

 ## Development

 ```sh
-cargo leptos build            # full app (server + wasm)
-cargo test --features ssr     # engine tests
-cargo build --features ssr --bin question_lint
+cargo leptos build            # server + wasm
+cargo test --features ssr     # tests/jetstream.rs needs PORTAL_TEST_NATS_URL
 ```

-Runtime configuration is env vars (see `src/main.rs`, and each
-content repo's `.gitea/workflows/deploy.yml` for the values in
-production): `NATS_URL`, `CONTENT_REPO`/`CONTENT_BRANCH`, Kanidm OIDC
-(`KANIDM_URL`, `OAUTH2_CLIENT_*`), optional `GARAGE_*` for uploads,
-`GITEA_API_TOKEN` for authenticated resource pulls,
-`AUTOMATION_READ_TOKEN` for the automation KV read endpoint.
-
-## Release and deploy
-
-Portal doesn't deploy itself — it publishes versions, and each site
-decides when to take one. The whole day-to-day surface is two
-commands:
-
-**Cut a release** (here):
+Content is linted by [iris](https://project.uhhm.no/uhhm/iris), which
+depends on this crate and carries the same version, so a content repo
+can check itself against the exact portal its instance runs:

 ```sh
-cargo release patch        # or minor / major
+iris check --path questions
 ```

-That bumps `Cargo.toml`, tags `v<version>`, and pushes; CI
-(`.gitea/workflows/publish.yml`) reacts to the tag, builds once, and
-attaches `portal-v<version>.tar.gz` (`portal` + `question_lint` +
-`hash.txt` + `site/`) to the Gitea release. Pkg files are
-content-hashed (`hash-files = true`; instances run with
-`LEPTOS_HASH_FILES=true`), so a freshly served page can never pair a
-stale cached bundle with new wasm. Plain pushes to `main` only run the
-tests (`test.yml`) — nothing reaches production from this repo.
+## Releasing

-**Roll it out** (in a content repo): edit one line in that repo's
-`.gitea/workflows/deploy.yml` —
-
-```yaml
-env:
-  PORTAL_RELEASE: v0.1.1   # <- bump, commit, push
-```
-
-Its CI downloads the pinned artifact, ships
-`/srv/app/<instance>/releases/<tag>`, flips `current`, rewrites the
-instance env from that repo's own Actions variables/secrets, restarts
-`app@<instance>`, and refreshes the Caddy route. Every rollout is a
-commit, so reverting a bad version is `git revert` + push. Sites
-upgrade independently: uhhm.no (uhhm/questions → `app@uhhm-portal`,
-:3010) and redoal.com (redoal/questions → `app@redoal-portal`,
-:3020) can pin different versions.
-
-Content changes never come through any of this — they hot-reload
-live from the content repos over NATS.
-
-**Add a site**: new content repo with a copy of an existing
-`deploy.yml` (change `INSTANCE`, port, domains), Actions variables
-(`KANIDM_URL`, `OAUTH2_CLIENT_ID`, `PUBLIC_URL`, `SITE_NAME`) and
-secrets (`NATS_URL`, `OAUTH2_CLIENT_SECRET`,
-`PORTAL_GITEA_API_TOKEN` — Gitea reserves the `GITEA_` prefix for
-secret names), a Kanidm OAuth2 client, and DNS. `site.yaml` in the
-content repo handles all branding; no portal changes needed.
+`cargo release patch` tags and pushes; CI builds the tarball and
+attaches it to the Gitea release. A site takes it by bumping
+`PORTAL_RELEASE` in its own content repo. See
+[operations](docs/operations.md).

+# Access
+
+Who may do what to what is compiled from content on every load into
+one Cedar policy set, and every server entry point asks that one
+policy. Identity stays Kanidm's; portal only decides.
+
+## What content compiles to
+
+| content | rule |
+|---|---|
+| a page with no `qualifies` | anyone may open and submit |
+| `qualifies: case_officers` | that group may open and submit |
+| `requires_chain: /start` | the visitor's verified answer lineage must reach it |
+| a resource with `public: true` | anyone may read it |
+| a resource with `requires_group: g` | that group may read it |
+| a desk resource's `transitions` | that group may make those moves |
+| an alternative's `self_transition` | the submitter may make it, from each state in `from`, with their link and their matching email |
+| an alternative's `invite: {group}` | the page's own group may invite into that group |
+
+Mutations always need a group, whatever `public` says. A resource with
+neither `public` nor `requires_group` is unreachable rather than open:
+the policy fails closed.
+
+## Reading the policy
+
+```sh
+iris check --path questions --access
+```
+
+prints every rule the content compiled to, as a table of who may do
+what from where to where. It is the fastest way to find a rule a
+content repo did not mean to write — a refusal available on the day a
+case arrives, a board that can decide a case it never received.
+
+## Asking it
+
+Every decision carries the rule ids that granted it. Refusals and
+every mutation are published on `portal.access.decided`.
+
+Other applications ask the same question over NATS request-reply on
+`portal.access.<site>.may`, with the same principal, action, resource
+and context the server uses internally — so an automation acting as a
+group gets exactly the answer a person in that group would.
+
+## The submitter
+
+A person who sent a form has no account. Their credential is the link:
+an unguessable chain hash, plus the email they gave, which the policy
+compares against the one stored on the record.
+
+What they may do, and from where, is `self_transition.from`. Its
+default is the initial state alone. A refusal reads "not found" while
+the record is somewhere the move could have been made from — so the
+endpoint cannot be used to discover which records or addresses exist —
+and "already processed" once the case has moved past it.

+# Architecture
+
+One Rust binary (Leptos SSR + hydrate, Axum underneath) serving any
+number of sites. The engine special-cases nothing: every page, form,
+desk and state graph a site serves is declared in its content repo,
+and instances differ only by environment variables.
+
+It composes with the surrounding stack rather than bundling it. Gitea
+hosts the content, NATS JetStream stores the events and projections,
+Kanidm provides identity, and anything downstream subscribes to the
+answer stream.
+
+## The pieces
+
+**Content** (`src/content/`) — YAML loaded from Gitea at boot and
+hot-swapped on a NATS reload signal. A bad push keeps the last-good
+content serving. The `questions/` tree is the router: file paths
+become URLs, `_section.yaml` applies to a whole directory, and
+`[name].yaml` serves any `/dir/<value>` with the segment fed into the
+page's resource keys. See [filesystem routes](design/filesystem-routes.md).
+
+**The lint** (`src/content/validate.rs`) — every rule a content repo
+is held to. It runs at boot, on every hot reload, and in a content
+repo's CI through [iris](https://project.uhhm.no/uhhm/iris), which
+depends on this crate and so applies exactly the version the instance
+runs.
+
+**State machines** (`src/aggregates/`) — `aggregates.yaml` declares
+each bucket's states and legal moves. A record's state is replayed
+from its own event history, undeclared moves are refused, and racing
+decisions are settled by CAS on the log's sequence. An empty history
+reseeds from the KV projection, so wiping the event stream strands
+nothing. See [state machines](state-machines.md).
+
+**Events and projections** (`src/events/`, `src/answers.rs`) — every
+submission and decision appends to a JetStream log and projects into
+a NATS KV bucket that pages read back, and publishes on
+`portal.answers.submitted` for automations to react to.
+
+**Answer chains** (`src/chain.rs`) — each submission hashes its
+parents, so a visitor's path through the questions is a verifiable
+lineage. `?chain=` links carry it; a `followup` page is offered only
+once the chain has earned it, and a page behind an answer somebody has
+not given is never offered.
+
+**Access** (`src/access.rs`) — who may do what to what, compiled from
+content on every load into one Cedar policy set that every server
+entry point asks. See [access](access.md).
+
+**People** (`src/people.rs`) — onboarding as a form. An alternative
+with `invite: {group}` creates the person in Kanidm, records their
+email, adds them to the group and mints a one-time credential link. A
+state may also grant a group on its own (`grants:`), so an approval
+that means membership needs no second step.
+
+**Mail** (`src/mail.rs`) — a state may declare the mail its arrival
+sends. Portal renders it and publishes on `portal.mail.send`;
+[gdo](https://project.uhhm.no/uhhm/gdo) delivers it and carries
+replies back on `portal.mail.received`, where they become notes beside
+the record. A note never moves a case.
+
+**Sweepers** (`src/announce.rs`, `src/deadlines.rs`) — the two things
+that move without a person. An announced page's window closes and its
+record becomes a "post what happened" task; a state with a deadline
+waits out its days and then makes the move itself. Both go through the
+same transition path as a desk button and publish the same event.
+
+**Resources** (`src/resource.rs`) — content can read a KV bucket,
+Gitea starred repos, org repos or releases, or any public JSON URL
+(SSRF fail-closed), reshaped by a content-declared `jq` filter. What a
+resource reads is never a client-supplied parameter: the client names
+a page and a feature, never a bucket or URL.
+
+**Maps** (`src/maps.rs`) — MapLibre is vendored and every tile, style
+and still image is proxied through portal, so a page with a map makes
+no third-party request and needs no consent banner.
+
+**Desks** — any Kv resource with `transitions` renders rows with
+per-state buttons and one shared confirm. Owners walk records through
+their graphs with no bespoke UI per bucket.

+on every hot reload, and in CI through `iris check`.

+```
+
+`mail.from` is required as soon as any state declares a mail.
+
+## A question
+
+One YAML file is one page.
+
+```yaml
+id: /apply              # defaults to the file's path
+name: Apply to build
+description: What we need from you.
+qualifies: case_officers        # a Kanidm group may open this page
+requires_chain: /start          # or: an answer they must already have given
+followup: true                  # keep it out of the nav until earned
+responsible: { name: Solveig, email: post@vestmark.example }
+event:                          # this page announces an occasion
+  starts: 2026-10-14T18:00
+  duration: 2h
+  place: The town hall
+place:                          # this page is about somewhere
+  lat: 59.8938
+  lon: 11.0332
+  zoom: 15
+  name: Tomter
+alternatives: [ ... ]
+```
+
+`qualifies`, `requires_chain` and `responsible` are inherited from the
+nearest `_section.yaml`. `event` makes a page an occasion with a time;
+`place` makes it a place, drawing a still map under the question and
+opening any `type: location` field on the page there rather than on
+the whole world.
+
+## An alternative
+
+One choice. Never two actions behind one heading: if two things can be
+done, they are two alternatives.
+
+```yaml
+alternatives:
+  - name: Send the drawings
+    description: We answer within twelve weeks.
+    action: /sent                  # the page to go to; /shape/{field} templates
+    record_as: applications        # the bucket the answer lands in
+    disabled: false
+    consequence: [What happens next]
+    encouragements: [It takes two minutes]
+    images: [/site/drawing.png]
+    features: [ ... ]
+```
+
+Three things an alternative may do instead of, or beside, recording an
+answer:
+
+```yaml
+    self_transition:               # the person moves their own record
+      bucket: applications
+      to: complete
+      from: [open, incomplete]     # defaults to the initial state alone
+      label: Send them
+    invite: { group: case_officers }   # onboard someone into Kanidm
+```
+
+`self_transition.from` is what keeps a person in dialogue with their
+case: an applicant written to for a missing drawing answers from
+`incomplete`, and may withdraw from wherever the case has got to.
+Omitted, it is the initial state alone, which is what a one-shot
+unsubscribe link means. Each state listed becomes its own access rule,
+and the lint refuses a `from -> to` the state machine does not declare.
+
+An `invite` needs a required `name` and `email` on the same
+alternative, and the inviting group must be allowed to invite that
+group by the policy.
+
+## A feature
+
+What an alternative offers, explained. A feature that is only layout
+is a feature wasted: each one says something true about the choice.
+
+```yaml
+    features:
+      - name: What you need
+        description: The case number from the letter.
+        icon: document
+        color: "#8ec2c0"
+        requirements: [ ... ]      # form fields
+        resource: { ... }          # live data
+```
+
+## A requirement (a form field)
+
+```yaml
+        requirements:
+          - name: email            # snake_case; this is the stored key
+            label: Your email
+            placeholder: you@example.no
+            type: email
+            optional: false
+            value: "{key}"         # a preset; a dynamic page's segment fills it
+```
+
+`type` is one of:
+
+| type | what it is |
+|---|---|
+| `text` | the default |
+| `email`, `tel`, `date`, `number`, … | anything else is passed straight through as the HTML input type |
+| `textarea` | several lines |
+| `prosekit` | a rich-text editor |
+| `select` | one choice, or `multiple: true` for any number |
+| `file` | an upload, with `accept:` and `multiple:` |
+| `location` | a pin on a map, stored as `{lat, lon, zoom}` |
+| `record` | the record this one belongs to |
+| `gesture`, `voice` | a drawn stroke or a recording, through a redoal relay |
+| `hidden` | a carrier value, no label row |
+| `module` | a widget the content repo ships |
+
+A `select` takes either inline `options: [...]` or a `resource:` to
+draw them from, with `id_field:` naming each item's stable id.
+
+A field may load its value from a resource when a sibling changes:
+
+```yaml
+          - name: contents
+            type: textarea
+            bind:
+              field: path          # the sibling to watch
+              resource: { source: { kind: url, url: "https://git.example/raw/{path}" } }
+```
+
+### type: record
+
+How one case belongs to another — an objection to the application it
+objects to, an appeal to the decision it appeals.
+

+            value: "{key}"         # arrives on the link, on a dynamic page
+```
+
+Nobody types one of these: the stored value is the parent's record id,
+which is a chain hash. It arrives the way it was given out, so the
+field carries rather than asks, and renders hidden. A submission
+naming a record that is not there is refused, so a reference in a
+stored record is one that resolved at least once.
+
+The other half is a listing that asks for the children:
+
+```yaml
+        resource:
+          source: { kind: kv, bucket: objections }
+          requires_group: case_officers
+          where: { field: case, equals: "{key}" }
+```
+
+## A resource
+
+Live data, declared by content and read by the server. What a resource
+reads is never a client-supplied parameter.
+
+```yaml
+        resource:
+          source: { kind: kv, bucket: applications }
+          key: abc123              # one record instead of the list
+          public: true             # or requires_group: case_officers
+          states: [approved, refused]      # only these; empty means all
+          where: { field: case, equals: "{key}" }
+          jq: ".[] | {name, url: .html_url}"
+          empty: Nothing decided yet.
+          transitions:             # the desk's buttons
+            - { from: complete, to: on_hearing, label: Send it out }
+```
+
+`source.kind` is one of `kv`, `gitea_starred`,
+`gitea_releases`, `url`.
+
+A spec with neither `public: true` nor `requires_group` is
+unreachable: reads fail closed, and mutations always need a group
+whatever `public` says.
+
+`states` and `where` narrow a listing. They matter most for a register
+that is public by law — public about what was decided, not about what
+was withdrawn — while the desk working the same bucket is a different
+spec and still sees all of it. A record that has no such field never
+matches: "everything that did not say" is not something a page can ask
+for by accident.
+
+## needs.yaml
+
+What the site is for, as a checkable spec: who wants what, which
+bucket the answer must land in, which group carries it to a finished
+state. The runtime never reads it. `iris check` proves the site meets
+it, and `iris replay` runs cases through the real engine.

+# Operations
+
+Portal does not deploy itself. It publishes versions; each site
+decides when to take one.
+
+## Cut a release
+
+```sh
+cargo release patch        # or minor / major
+```
+
+That bumps `Cargo.toml`, tags `v<version>` and pushes. CI
+(`.gitea/workflows/publish.yml`) reacts to the tag, builds once, and
+attaches `portal-v<version>.tar.gz` (`portal`, `iris`, `hash.txt`,
+`site/`) to the Gitea release. Plain pushes to `main` only run the
+tests: nothing reaches production from this repo.
+
+The same job re-pins, tests and tags [iris](https://project.uhhm.no/uhhm/iris)
+to match, so a portal change to anything the lint reads fails the
+release rather than the next content push.
+
+Before cutting, move the `Unreleased` lines in `CHANGELOG.md` under a
+heading for the new version. That section becomes the release notes,
+and the table at the end of the file records which version each site
+runs.
+
+Pkg files are content-hashed (`hash-files = true`, instances run with
+`LEPTOS_HASH_FILES=true`), so a freshly served page can never pair a
+stale cached bundle with new wasm.
+
+## Roll it out
+
+In the content repo, one line of `.gitea/workflows/deploy.yml`:
+
+```yaml
+env:
+  PORTAL_RELEASE: v0.4.0
+```
+
+Its CI downloads the pinned artifact, ships
+`/srv/app/<instance>/releases/<tag>`, flips `current`, rewrites the
+instance env from that repo's own Actions variables and secrets,
+restarts `app@<instance>` and refreshes the Caddy route. Every rollout
+is a commit, so reverting a bad version is `git revert` and a push.
+
+Sites upgrade independently and may pin different versions.
+
+Content changes never come through any of this: they hot-reload live
+from the content repos over NATS.
+
+## Add a site
+
+A new content repo with a copy of an existing `deploy.yml` (change
+`INSTANCE`, the port and the domains), Actions variables
+(`KANIDM_URL`, `OAUTH2_CLIENT_ID`, `PUBLIC_URL`, `SITE_NAME`) and
+secrets (`NATS_URL`, `OAUTH2_CLIENT_SECRET`, `PORTAL_GITEA_API_TOKEN`
+— Gitea reserves the `GITEA_` prefix for secret names), a Kanidm
+OAuth2 client, and DNS. `site.yaml` handles all branding; no portal
+change is needed.
+
+## Environment
+
+Runtime configuration is environment variables; `src/main.rs` is the
+authority and each content repo's `deploy.yml` holds the production
+values.
+
+| | |
+|---|---|
+| `NATS_URL` | events, projections, sessions, content reload, access questions |
+| `CONTENT_REPO`, `CONTENT_BRANCH` | the repo that is the site |
+| `KANIDM_URL`, `OAUTH2_CLIENT_ID`, `OAUTH2_CLIENT_SECRET` | sign-in |
+| `KANIDM_API_TOKEN` | invites and `grants:`; unset, neither happens |
+| `PUBLIC_URL`, `SITE_NAME` | what the site calls itself in links and mail |
+| `GITEA_API_TOKEN` | authenticated resource pulls |
+| `AUTOMATION_READ_TOKEN` | the automation KV read endpoint |
+| `GARAGE_*` | uploads |
+| `MAPBOX_TOKEN` | map tiles, proxied; unset, maps are off |
+| `GARAGE_*` (4) | attachments; see below. Unset, upload fields fail closed |
+| `PORTAL_RATE_BURST`, `PORTAL_RATE_SECONDS` | the rate limit; see below |
+
+Mail is delivered by [gdo](https://project.uhhm.no/uhhm/gdo), a
+separate unit on the same host reading the same NATS.
+
+## Rate limiting
+
+Every request passes a per-caller-IP limit before a session is loaded
+or a handler is entered: a burst of 30, refilled one every two
+seconds. A visitor filling in a form never reaches it (a page load
+fetches several resources at once); a script does.
+
+| | |
+|---|---|
+| `PORTAL_RATE_BURST` | how many requests at once, default 30 |
+| `PORTAL_RATE_SECONDS` | seconds per refilled request, default 2 |
+
+Either set to `0` turns it off, for an instance behind something that
+already does this. The caller is read from `X-Forwarded-For` or
+`X-Real-IP`, falling back to the socket — all of these instances are
+behind Caddy.
+
+This is a fence, not an accounting system. What keeps uploads honest
+is the policy check on the route itself.
+
+## Attachments
+
+A `type: file` field stores an object key in the record. The file
+comes back out at:
+
+    GET /attachment/{bucket}/{record}/{field}
+
+which reads the key out of that record rather than taking one from the
+caller, so a file can only be fetched through a record somebody is
+allowed to see, and a leaked key is a link to nothing. Reading it
+needs the same policy permission as reading the bucket on a desk.
+
+Uploads need a bucket and a key in the Garage on the host:
+
+```sh
+garage bucket create <site>-attachments
+garage key create <site>-portal-uploads
+garage bucket allow --read --write <site>-attachments --key <site>-portal-uploads
+```
+
+then `GARAGE_S3_ENDPOINT`, `GARAGE_ACCESS_KEY`, `GARAGE_SECRET_KEY` and
+`GARAGE_UPLOADS_BUCKET` in that instance's env. Unset, an upload field
+fails closed rather than appearing to work and storing nowhere.
+
+## Who deploys what
+
+Both hosts deploy from CI now, and a rollout is the same commit either
+way: bump `PORTAL_RELEASE` in the site's own content repo.
+
+| | runner | how it is allowed to |
+|---|---|---|
+| ergo | `runs-on: bare` | the runner is privileged and writes `/srv/app` and `/etc/app` itself |
+| kasse | `runs-on: fish` | the runner is not privileged. It may run one root script, `/usr/local/bin/deploy-portal-instance`, which checks the instance against a fixed list and the tag against a release-tag shape before touching anything |
+
+The kasse grant is a single sudoers line
+(`/etc/sudoers.d/30-portal-deploy`). It exists so a workflow can pick
+which of three known instances gets which published portal tag, and
+nothing else.
+
+Both paths health-check the instance afterwards **without** a forwarded
+header. A check that sends the header Caddy would send cannot tell you
+the site is broken for everything that is not Caddy, which is how
+v0.5.1 reached a host.
+
+`IRIS_RELEASE` in a repo's lint workflow should equal its
+`PORTAL_RELEASE`. Bump it only once iris's own publish job has attached
+the binary for that tag - portal's release tags iris, but iris builds
+and uploads on its own run, and a pin bumped in between fails the lint
+on a download that is not there yet.

+# State machines
+
+`aggregates.yaml` declares what a bucket's records may be and how they
+move. It is the one file that decides what is possible; the pages only
+decide who presses what.
+
+```yaml
+aggregates:
+  - bucket: applications
+    initial: open
+    states:
+      open:        { event: received }
+      incomplete:  { event: incomplete }
+      complete:    { event: complete }
+      on_hearing:  { event: on_hearing }
+      recommended: { event: recommended }
+      approved:    { event: approved }
+      refused:     { event: refused }
+      withdrawn:   { event: withdrawn }
+    transitions:
+      open:        [incomplete, complete, withdrawn]
+      incomplete:  [complete, withdrawn]
+      complete:    [incomplete, on_hearing, refused, withdrawn]
+      on_hearing:  [incomplete, recommended, refused, withdrawn]
+      recommended: [approved, refused, withdrawn]
+```
+
+`transitions` is an arbitrary directed graph. Cycles are allowed and
+are often the honest shape: a case sent back for the drawing it was
+missing returns to a stage it was already past. A good ending may sit
+partway along — an authority that changes its own decision finishes
+the case without walking to the end of the line.
+
+Each state's `event` string is the name written into the log, and must
+be unique within the bucket. A record's state is replayed from its own
+events, so renaming an event orphans the records that carry the old
+name: when rebuilding a live site, keep the names it already has.
+
+## What a state may carry
+
+Beside its `event`, a state may declare three things that happen when
+a record arrives in it.
+
+### mail
+
+```yaml
+      approved:
+        event: approved
+        mail:
+          to: submitter            # or one fixed address
+          subject: "Your application"
+          body: |
+            Hello,
+
+            {property_address} is approved. The decision is at
+            {site}/status/{chain}.
+```
+
+`{field}` is any field of the record, plus `{site}`, `{chain}`,
+`{email}`, `{bucket}` and `{state}`. The body is markdown; it is sent
+as text with an HTML alternative. `to: submitter` means the record's
+`email` field, and the lint then requires every form filling that
+bucket to collect a required `email`.
+
+Portal renders it and publishes on `portal.mail.send`. gdo delivers
+it, and a reply comes back on `portal.mail.received` as a note beside
+the record. A note never moves a case.
+
+### grants
+
+```yaml
+      approved:
+        event: approved
+        grants: approved_firms
+```
+
+The person the record is about becomes a member of that group when the
+record arrives here. An approval that *means* membership should not
+also need somebody to remember to invite them afterwards.
+
+The lint requires every form filling that bucket to collect a required
+`name` and a required `email`, because by the time a desk presses
+approve there is nobody left to ask. An instance with no Kanidm
+configured grants nothing and says so in the log; the transition
+itself always stands.
+
+### after
+
+```yaml
+      on_hearing:
+        event: on_hearing
+        after: { days: 42, to: recommended }
+```
+
+The move a clock makes rather than a person. A hearing that gets no
+answer in six weeks has to go on without one, and nobody in the
+building is in a position to press that button.
+
+A deadline may only do what a person could have done: `after.to` is
+held to the same declared edge as a desk button, and content that says
+otherwise is refused when it loads, not when the hour comes round. The
+wait is measured from the record's last move. The move goes through
+the same transition path, fires the same mail, and lands on
+`portal.answers.submitted` like any decision, stamped `deadline`.
+
+The unit is days and the sweep is hourly. This is a deadline, not a
+job queue.
+
+## attended_by
+
+```yaml
+  - bucket: newsletter
+    initial: open
+    states: { open: { event: received } }
+    attended_by: n8n newsletter compose
+```
+
+Names what consumes a bucket no page reads back. The lint refuses a
+bucket that a form fills and nothing attends — a question was once
+dropped and its answers silently fell out of every reader's view, and
+this is the contract that replaced the convention.
+
+## Who moves what
+
+Nothing in this file says who. A move becomes possible for somebody
+when a page offers it:
+
+- a desk resource's `transitions` gives it to that resource's
+  `requires_group`;
+- an alternative's `self_transition` gives it to the person who sent
+  the record, by their link and their email, from the states its
+  `from` names;
+- a state's `after` gives it to the clock.
+
+All three compile into the same [access policy](access.md), and the
+engine refuses anything the graph above does not declare, whoever asks.
+
+## Testing one
+
+`iris replay` runs cases through this exact machinery — the same
+`store_answer` and `transition` the running site uses, against a
+throwaway JetStream, reporting what the engine accepted and refused.
+
+```sh
+docker run -d --rm -p 127.0.0.1:14222:4222 nats:2.14.6-alpine -js
+iris replay --path questions --nats nats://127.0.0.1:14222 --cases cases.jsonl
+```
+
+Each line of `cases.jsonl` is one case: a need, a record, and the
+states it walks. Point it at a throwaway NATS, never a site's own: it
+writes.
