Introduces a fifth capability kind. `files` was `execution` — never grantable,
because it meant the OWNER'S filesystem. It is now `confined`: execution-shaped, but
the kernel enforces the boundary because the account has its own Linux user, its own
home, and no permission above it.
The rule that makes `confined` mean something lives in authorize.ts, once: a confined
grant is DROPPED for an account with no osUser. So "granted but unconfined" resolves
to no access rather than to the owner's home — which is what it would otherwise
resolve to, since getOwnerHomeDir ignores the email it is handed whenever HOME_DIR is
set. One rule covers the HTTP routes, the websocket doors and the dock, instead of
each router remembering.
resolveHomeDir(userId) is the new seam and it reads the row rather than the token, for
the same reason authorize.ts re-reads role: provisioning a Linux account for an
existing member has to take effect on the next request, not in thirty days.
The file browser resolves it in middleware and puts it on ctx user, because
getRootDir is called from fifteen places in that router. Making it async would have
meant editing fifteen call sites, and the cost of missing one is serving the owner's
home to a member. Now a handler cannot run without the answer.
Two things a real run caught:
- /ls seeds Downloads/Documents into the home as the service user, which is EPERM
against a 700 home owned by the member — it took the whole listing down. Seeding is
now best-effort there and happens at provision time instead, as the member.
- .unique() on os_user made db:push ask whether to TRUNCATE users, which is
unanswerable non-interactively. uniqueIndex instead, per databases/CLAUDE.md.
Verified: a member without a Linux account is refused by name; with one, resolves to
their own home and NOT to HOME_DIR; the owner still resolves to HOME_DIR; and every
.. escape is refused while an absolute path is rebased under the root.
Terminal is still execution — that is the next stage.

ALL_DOCK_ITEMS was a hardcoded list of everything, so a fresh machine offered Photos, Jellyfin,
Transmission and the rest — each leading to a screen reporting itself unavailable — and adding a sidecar
meant editing the shell. Neither survives sidecars shipping from their own repositories.
Split in two. CORE_DOCK_ITEMS is the baseline that exists on every install: chat, files, terminal, the
app's own screens, and Gitea, which is in the light profile because it fronts a remote instance.
Everything else is derived from installed sidecars' UI manifests, delivered with /capabilities.
Sent with the capability answer rather than fetched separately so the dock has ONE source. Two requests
means two moments, and a dock rendered between them shows a tile for something uninstalled or nothing
for something installed. Filtered by capability server-side too: a member is not handed the manifest of
a feature they cannot use, because "hidden in the client" is the kind of privacy that lasts until
someone opens the network tab.
Verified live. The owner — who bypasses every permission check — does not bypass this: /photos is absent
from routes and present in deniedRoutes because Photos is not installed. Flipping a row's `enabled`
makes its tile leave and return with no process touched.
Two things fell out. A manifest can declare extraTiles, because CalDAV is one sidecar presenting as
Calendar AND Contacts, and collapsing them to keep the model tidy would make the app worse. And
DEFAULT_DOCK_PATHS no longer pins /music: useDock drops a path with nothing behind it, so the default
dock came up a tile short on any machine where Music was never installed — a default that references an
optional feature is how an app looks subtly wrong on a fresh install for no stated reason.

Two gaps, both from the same root: the app knew what an account MAY use and not what this server
actually HAS.
Availability is now subtracted server-side in the /capabilities answer. "Installed" is orthogonal to
"permitted" and the owner is subject to it — the owner bypasses every permission check, but a capability
they hold unconditionally still means nothing if its sidecar was never installed. Without this the dock
on a fresh machine lists Photos, Jellyfin, Transmission and the rest, each leading to a screen that
reports itself unavailable.
Computed on the server rather than intersected in the client, so the rule lives in one place: the dock
already reads `/capabilities`, and making it read a second list and combine them is how a member's dock
and an owner's dock drift apart. `unavailable` is returned alongside `deniedRoutes` because the two mean
different things to a UI — "not yours" versus "not here yet, install it".
A disabled sidecar counts as unavailable: disable stops the process and its container, so the feature
genuinely does not work, and leaving its icon would make disable look broken rather than effective.
Reading install state failing subtracts NOTHING, matching useCapabilities' deliberate fail-open.
Each entry now also carries a UI manifest — name, icon, colour, rootRoute, routes — because a sidecar
shipping from its own repository has to be able to say what it looks like. The icon is a NAME rather
than an imported component: a manifest has to survive being JSON from marketplace.officer.dev, which a
lucide import cannot make. Tests pin the manifests against the capability registry, so a tile cannot
appear for a route the server guards differently, and against each other, so two sidecars cannot claim
one root route.
No backfill, by decision: this is proven on a blank machine first and applied to alpha from scratch.

the server half of the previous commit, which belonged with it. the frontend
guard needs both lists: absence from `routes` cannot tell a route this
account lacks from a route no capability claims, so without this the guard
permits everything.

GET /api/user/capabilities is what the caller may reach, and every account
may ask — it is mounted on a core capability so an account granted almost
nothing can still find out what it has. the dock and route guards read it.
it is a courtesy, never enforcement: hiding an icon is not access control
and the 403 in origin-validation stays the lock.
GET/PUT /api/users/capabilities edit the policy, owner-gated. the write path
is where the registry's authority over capability keys is applied, which is
why the column has no CHECK: unknown keys and non-app kinds are refused
rather than stored for the resolver to drop on read.
the exception is `selfService`. useAuth calls PUT /api/users to change your
own name and avatar, and that route has always lived on the same router as
the owner-only account administration around it — so declaring /users an
admin capability locked every member out of their own profile. moving it to
/api/user would be tidier and would break every shipped mobile client, so
instead the registry says out loud that this one route is not what the
capability around it is. exact method and exact path, so it cannot widen:
verified that PUT /api/users passes while GET /api/users, PATCH
/api/users/:id/role, DELETE /api/users/:id and PUT /api/users/:id are all
still refused.
