Two halves of the same evening.
Uploads were one-way. A `type: file` field put an object in the bucket
and wrote its key into the record, and nothing ever read it back - a
desk showed `0aba5734-...-drawing.pdf` as a string with no link, so a
builder could receive drawings and never open one.
`GET /attachment/{bucket}/{record}/{field}` streams it. The key is not
the credential and is not taken from the caller: it is read out of the
record named, so a file is reachable only through a record somebody is
allowed to see, and a key that leaks off a desk is a link to nothing.
And there was no rate limiting anywhere. A burst of 30 per caller IP,
refilled one every two seconds, outside the session layer so anyone
over it is turned away before a handler is entered. Well above a
person filling in a form - a page load fetches several resources at
once - and well below being a nuisance. PORTAL_RATE_BURST and
PORTAL_RATE_SECONDS retune it; either 0 turns it off for an instance
behind something that already does this.

/upload asked nothing. It took a file, capped it at 20 MB, and wrote
it to the bucket for whoever sent it - no session, no page, no policy.
It was the one server entry point that did not ask the question every
other one asks, and on a site whose forms are public that makes the
route public too: a free disk for anyone who finds the host.
Harmless while no instance had storage configured, which is why it sat
there. kasse now has a garage wired to klingenberg's portal, so it is
not harmless any more.
An upload now carries the question and the alternative the file is
being attached to. The page has to exist, the alternative has to be
open and to actually declare a `type: file` field, and the policy has
to allow Submit on that page for whoever is asking - checked after the
bytes are read and before any of them are written.

Every outbound fetch - Gitea content at boot and on reload, the raw
asset proxy, the repo-info endpoint, the content-declared url resource
- built its own reqwest client with no timeout and read whole bodies
with .text(). `crate::http` is now the one client (5 s connect, 20 s
per request, 5 redirects) with capped body readers: 2 MB for a url
resource, 8 MB for a Gitea reply, 32 MB for a proxied asset; one byte
over is an error, never a truncated document.
The upload handler read a whole field into memory before comparing it
to the 20 MB cap, and axum's 2 MB default body limit had made that cap
unreachable anyway. It now reads chunk by chunk and refuses the moment
the cap is crossed; the /upload route raises the body limit to match.

Drops porting-history narratives (dodrenett), superseded-behavior
explanations, and restatements of what the next line does. Constraint
notes (fail-closed policies, CAS semantics, cascade behavior, id
uniqueness) stay, just shorter. No code changes.

Leptos/Axum app that renders a Question/Alternative/Feature schema
loaded from a sibling content repo (portal-content). Kanidm OIDC login,
content-driven authorization (Question.qualifies), a generic NATS
KV-backed resource + state-transition mechanism (no bespoke "applicant"
concept baked into the runtime - it's all content), a SHA-256 DAG chain
tying submissions and decisions together, and the "YES - Rasterized
Lines" piece (ported from the live uhhm.no site) as the landing hero.
