`grabs.infohash` is unique and grabs point at their target
polymorphically, so nothing cascaded them off a deleted movie or series.
An orphan holding an infohash then blocked the row a later grab of the
same release needed: the upsert only reclaims a `vanished` row, so the
insert did nothing while the new title was still flipped to
`downloading`. It never imported, and `/api/downloads` attributed the
torrent to a title that no longer existed.
Deletes now clear the grabs, and the upsert also reclaims a row whose
target is gone whatever its state — which heals the databases that
already have orphans. A row belonging to a live title stays off limits,
so the restart case still cannot let one title steal another's torrent.

Logging in before the first call turned a stale or wrong password into a
hard failure on calls that would have succeeded: an instance that bypasses
authentication for arr's address answers everything, and never needed the
credentials at all. Authentication is now established on the first 403.
The health probe was reading a 403 from `app/version` as healthy, on the
reasoning that a live daemon is all the lamp claims. That is exactly the
state arr cannot use, and it left the lamp green while every grab and every
reaper tick failed on rejected credentials. It now lists torrents through
the configured client, so the lamp fails when arr's own calls do.

qBittorrent's add call answers `Ok.` and nothing else — no hash, no name,
no duplicate signal — so arr derives the v1 infohash from the magnet or the
`.torrent` bytes before the call and looks the torrent up by it. That also
drops Transmission's numeric torrent id: the hash is the only identity now.
The reaper needs "stopped because a share limit was reached", and
qBittorrent's state field cannot tell that apart from a hand-paused torrent.
So the ratio and idle counters are checked against the limits arr set, and a
torrent stopped by a global limit reads as still seeding rather than being
deleted.
The WebUI needs a login, so `ARR_QBITTORRENT_USERNAME` and
`ARR_QBITTORRENT_PASSWORD` join the env-only secrets; leaving both unset is
valid for an instance that whitelists arr's subnet.
Verified against qBittorrent 5 (WebAPI 2.15.1) in a container: it rejects
`setShareLimits` without `shareLimitAction`, which 4.x ignores, so it is
always sent.

A zero download rate is not a stalled torrent: one between peers reads
zero for a poll or two and finishes fine, and at §9.8's 15s cadence that
flicker would raise the one chip reserved for a download that never
finishes. Transmission already decides this with its own stalled window;
carry isStalled and use it.
Transmission has no route to Prowlarr, and Prowlarr redirects a
.torrent link to a magnet that a file fetch cannot follow. arr fetches
the link itself and sends Transmission a magnet or the torrent bytes.

Eleven empty crates per DESIGN.md §11, versions and lints pinned once in the
root manifest, Justfile carrying the §12 gate, nix dev shell.
The frontend steps in `just ci` no-op until web/ exists. arr-core carries one
placeholder test because `cargo nextest` fails a zero-test run, and relaxing
that would let a broken filter go green later.
Closes#1
