Release 0.2.3

validate_questions now rejects content where a record_as bucket is
read by nothing: every bucket must be listed by some Kv resource in
the same repo (a desk) or carry aggregates.yaml's new attended_by
annotation naming the automation that consumes it - no publicly
collected answer may land where nothing reads.

Separately, all server-fn resources (question/user/nav) move to a
PortalShell above the routes, created once and provided via context.
Per-page Resources broke on the first client-side navigation: the
remounted component's fresh Resource consumed a stale SSR hydration
buffer - the nav list [[id, name], ..] deserialized as a Page (serde
fills structs from sequences in field order), so uhhm.no's landing
question rendered chain-gated behind its own nav entry instead of
the /develop/proposal form.

+A content-driven question engine: one Rust binary that turns a Git
+repo of YAML into a live site — pages, forms, review desks, and state
+machines, with a durable event-sourced record of every answer
+underneath. The engine special-cases nothing: everything a site
+serves is declared in its content repo, and the same build serves any
+number of sites.
+
+Point an instance at a content repo and that repo *is* the site:
+pages, copy, state graphs, and branding (`site.yaml`: title,
+wordmark, and which hero the landing page opens on — the YES canvas,
+a gesture-drawing canvas wired to a relay, or plain copy). Content
+pushes hot-reload every running instance; instances differ only by
+env vars. [uhhm.no](https://uhhm.no)
+([uhhm/questions](https://project.uhhm.no/uhhm/questions)) and
+[redoal.com](https://redoal.com)
+([redoal/questions](https://project.uhhm.no/redoal/questions)) are
+two faces of the same binary, deployed from the same release
+artifact.
+
+It composes with the surrounding stack rather than bundling it: Gitea
+hosts and serves the content, NATS JetStream stores events and
+projections, Kanidm provides identity, and anything downstream
+(automations, newsletters, onboarding) subscribes to the answer
+stream.

-## Deploy
+## Release and deploy
 
-Pushing `main` triggers `.gitea/workflows/deploy.yml` on the
-bare-metal runner: release build, ship to
-`/srv/app/uhhm-portal/releases/<sha>`, flip the `current` symlink,
-restart `app@uhhm-portal`, reload Caddy. Content changes never come
-through here — they hot-reload live from the `questions` repo.
+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):
+
+```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` + `question_lint` +
+`site/`) to the Gitea release. Plain pushes to `main` only run the
+tests (`test.yml`) — nothing reaches production from this repo.
+
+**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.

+# Filesystem routes, sections, and where chains fit
+
+Status: implemented in v0.2.0 (2026-08-24) — all three phases, with
+one deviation: dynamic-page params substitute into resource keys via
+server-side `resolve_question` at lookup time (get_question,
+find_feature, submit_answer all resolve concrete paths), so no param
+threading exists client-side. The user-facing routing contract is
+documented in uhhm/questions' README ("Routing: the tree is the
+router"); this file stays as the design rationale.
+
+## What exists today, precisely
+
+- A question's `id` doubles as its URL. Filenames are meaningless:
+  `questions/` is loaded as a **flat** directory (both the Gitea
+  loader and `question_lint --path`), every `*.yaml` becomes a
+  `Question` keyed by its own declared `id`.
+- Hierarchy exists only as strings: `action: /proposed` edges, plus a
+  manual `followup: true` flag that hides post-submission pages from
+  the nav. The graph is invisible in a repo listing — you open every
+  file to learn the flow. (uhhm's actual graph: `/` fans out to three
+  followups; `/develop` → `/develop-proposal` → `/proposed` is a
+  two-step flow flattened into three top-level files.)
+- Criteria are per-file: `qualifies: <kanidm-group>` on a question,
+  `requires_group` on a resource. Gating a whole area means
+  repeating the flag in every file of that area.
+- Chains are query-string lineage: submitting hashes
+  `(question, parents, responses, ts)` into `chain_hash`, the next
+  page is `action + ?chain=<hash>`, and holding a chain is itself a
+  capability (`self_transition` + email second factor). `chain.rs`
+  reserves DAG shape (multiple parents) but nothing produces it yet.
+- `Question.route` is a declared-but-never-read field — a fossil of
+  this exact idea.
+
+## The proposal, in three phases
+
+### Phase 1 — the tree is the router
+
+Directory structure becomes the URL structure, next-js style:
+
+```
+questions/
+  index.yaml              → /
+  applied.yaml            → /applied
+  develop/
+    index.yaml            → /develop
+    proposal.yaml         → /develop/proposal
+    proposed.yaml         → /develop/proposed
+  review/
+    index.yaml            → /review
+```
+
+- `id:` becomes optional and **derived from the path** (`index.yaml`
+  names its directory). An explicit `id:` still wins so both content
+  repos keep working unchanged; lint warns when it disagrees with the
+  path, and the field can retire later along with `route`.
+- `action:` accepts **relative references**: `action: proposed`
+  resolves against the file's directory, `action: /subscribed` stays
+  absolute. Resolution happens at load time, so validation and the
+  runtime see absolute ids exactly as today. A flow directory becomes
+  self-contained: rename `develop/` and every internal edge moves
+  with it.
+- **`followup:` is inferred**: `index.yaml` files are nav pages,
+  non-index files are followups unless they say `nav: true`. This
+  matches the real content exactly (uhhm's four `followup: true`
+  files are precisely its non-index leaf pages) and deletes a flag
+  people must remember.
+- Loader: switch from the per-directory contents API to Gitea's git
+  trees API (`/git/trees/{branch}?recursive=true`) — one request for
+  the whole tree instead of one per directory, which the flat loader
+  should be using anyway.
+
+### Phase 2 — sections: criteria scoped by URL prefix
+
+A `_section.yaml` in any directory applies to everything beneath it
+(underscore = not a page, like next's private folders):
+
+```
+questions/review/_section.yaml:
+  qualifies: portal_owners
+  responsible: { name: Bendik, contact: … }
+```
+
+This is the URL/criteria interplay actually worth having: **a URL
+prefix becomes a trust boundary**. "Everything under /review is
+owner-only" is one line in one place, instead of a flag per file that
+drifts. Per-question `qualifies` still overrides (tighter or looser —
+lint should warn on looser). Sections are also the natural home for
+shared `responsible` contacts and, later, per-section branding
+accents.
+
+### Phase 3 — dynamic segments, and chains stay out of the path
+
+Two criteria axes exist: **who you are** (Kanidm group) and **what
+you've done** (holding a chain). Phase 2 scopes the first by prefix;
+phase 3 does the same for the second, plus gives records addresses:
+
+- `[record].yaml` — a dynamic segment, one YAML file rendered per
+  record: `questions/review/[record].yaml` serves `/review/<key>`,
+  with the param available to the page's `ResourceSpec.key`. Today a
+  single record is only reachable through a desk row or a
+  `?chain=` link; this gives every record a real, gated URL —
+  linkable from review desks, automations, and n8n notifications.
+- `requires_chain: <question-ref>` (page- or section-level): the page
+  only renders for a visitor whose chain tip answers the referenced
+  question. Today's followup pages are soft-hidden (out of nav) but
+  fully reachable; this makes "you must have come from X" an actual
+  criterion, declared with a relative ref like actions are.
+
+**Deliberately not proposed: encoding the chain in the path.** The
+page tree is static structure; the chain is runtime lineage and a
+bearer capability. Putting it in the path makes it look canonical and
+shareable — exactly what a capability URL shouldn't invite — and a
+DAG (the reserved multi-parent shape) doesn't linearize into a path
+anyway. `?chain=` stays a query parameter: pages keep one canonical
+URL, lineage rides along only when it's actually held.
+
+## Migration
+
+Phase 1 is fully backward compatible (explicit `id` wins, flat repos
+are just trees of depth one). The content repos migrate by `git mv`:
+uhhm's develop flow nests under `develop/`, its followups either stay
+top-level (`/applied` keeps its URL) or move with their flows if URL
+churn is acceptable; redoal's three files are already the tree. Lint
+learns the same resolution rules in the same commit, so a bad
+reference stays a caught push, never a 404.
+
+## Order of value
+
+Phase 1 is cheap and pays immediately (the repo listing becomes the
+sitemap). Phase 2 is small and unlocks gated areas properly. Phase 3
+is the real feature work — `[record]` pages change what desks and
+automations can link to — and can wait until something concrete needs
+it.
