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.

Five things a building authority needed and portal could not say,
found by building one and replaying its cases through the engine.
The one that mattered: a submitter could only ever act on a record
nobody had touched. `access.rs` pinned a self_transition's from-state
to `open`, though the runtime had always passed the real state and
asked. So the applicant written to for a missing drawing could not
send it, and nobody could withdraw once anything had happened.
`self_transition` now takes `from: [state, ...]` and compiles one rule
per state; omitted it still means the initial state alone, which is
what every unsubscribe link already meant.
Then the four beside it. A record can belong to another record
(`type: record`, `of:`), with `where: { field, equals }` on a listing
as the other half, so an application's page lists the objections that
name it. A public view can be narrowed to the states worth showing,
so a register that is public by law is public about what was decided
and not about what was withdrawn. A state can grant a group, so an
approval that means membership needs no second step. And a state can
be moved by a clock (`after: { days, to }`, src/deadlines.rs) - held
to the same declared edge as a desk button, firing the same mail,
publishing the same event.
Also: the README is a README again, and everything that was crowding
it is in docs/ - architecture, content reference, state machines,
access, operations.
95 tests, up from 82.
