19c65e8f4b Carry the login itself, and clean up after any failed read
Two things were conflated. Reloading the list bumped the generation, and
the import treated that as its login having changed — so a routine
refresh aborted a healthy import and told the user their account had
moved. The listing and the login are separate facts: the login that
listed a row is now carried with it, and the generation decides only
what may be marked imported.

The local playlist is also created before it is read, so anything
stopping the read left it behind empty — a login that moved, but equally
a server that did not answer. The import reports whether it completed,
and an incomplete one takes its empty playlist with it. A playlist that
genuinely had nothing to add keeps it.

24dd530cbc Do not mark a row imported once its listing is gone
The last write is followed by a pause, and an empty remote playlist
never reaches a check at all, so the list could be replaced before the
import reported itself finished. Marking it then attached to whichever
row carries that ID now — on another account, a different playlist
shown as already imported.

Clearing the in-progress state stays unconditional: it describes a row
that is no longer there either way.

e767bb9a22 Take the listing at selection, not at import
Capturing it where the import starts was too late for the one case that
needed it. The merge dialog waits on the user; a reload landing while it
is open replaces the list and re-bases the credential, and confirming
afterwards captured the new generation and passed every check — reading
a row that no longer exists under whoever now owns the account.

The listing is recorded where the row is chosen and carried to the
import, so what answers the dialog is the list that asked the question.

8a97c6da56 Tie an import to the listing it was chosen from
The credential baseline was recorded before the list it describes had
arrived, and cleared alongside it. A reload landing while an import was
still running therefore moved the baseline under it: the import passed
its check against a login that had never listed the row it was working
on, and a batch resumed through rows that no longer existed. A failed
reload left the same wrong baseline standing with the old rows still on
screen.

The baseline is now recorded where the rows are, so a failed load leaves
the previous login in place, and a generation names the listing itself —
captured by the batch and by each import, so replacing the list stops
what was chosen from it rather than re-authorising it.

26cc4aba25 Bind the playlist import to the login that listed it
Checking that some credential exists was the wrong question. Everything
on screen was read with one particular login, and a replacement is a
different person's account on the same server — its playlist IDs mean
something else entirely, so importing "the same" playlist under it
fetches whatever that ID happens to name there. The credential the list
was loaded with is now recorded, and every import is checked against it
rather than against whatever is current.

The two checks around creating the local playlist are a suspension
apart, so the login can still go between them. Nothing has been read at
that point, and an empty playlist named after somebody else's is not
worth keeping.

13b1fe9c0f Close the two ways a merge outlived its login
The merge dialog waits on the user, so the login can go between choosing
a playlist and confirming it. Reading it then returned quietly: the row
stayed in its importing state with nothing running, and a batch went on
to the next playlist. It now reports what happened and clears up after
itself, like every other way an import stops.

The merge that dialog starts is detached from it, so dismissing the
dialog was never the merge finishing — a batch resumed alongside it and
could begin the next playlist under whoever replaced the login. It is
waited for now, which is what makes the batch sequential.

a9ef6ca0c5 Stop the whole batch when one import loses its login
Importing every playlist creates each local one before reading it, so
aborting a single import left the loop free to carry on: an empty
playlist for each remaining title, or the rest read under whoever
replaced the login. The batch now ends where the first abort happened,
and nothing is created for a login already known to be gone.

00bab2ae63 Stop a playlist import that outlived its login
Videos are read with one account's credential and written one at a time
into a local playlist, which is not account-scoped: it belongs to
whoever uses the device and syncs to iCloud. The sheet can be dismissed
and somebody else signed in on the same server while the import is still
running — nothing cancels it — and the rest of one person's private
playlist would land in the other's library.

The credential is checked before every write rather than only at the
start. What was already written stays: it was imported under the login
that asked for it.

395b8eb083 Refuse a login whose Apple identity moved under it
Storing checked that the identity scope was resolved, but not that it
was still the one the login was made under. Credentials are filed per
identity, and the round trip leaves room for the scope to move — the
account obtained here would then be written into somebody else's
namespace and synced to their Keychain.

Only a move between two named identities counts. Unresolved at either
end is left to the storing side, which already refuses to write under a
scope it cannot name; rejecting it here as well would turn an ordinary
sign-in that began before iCloud settled — or a tokenless scope
revalidating on activation, which it does every time — into a failed
login.

361f19b762 Fence the instance browser's first load, not only its next page
Pagination carried the login it was requested for, but the load that
fills the tab in the first place did not. Its subscriptions, feed and
playlist requests all resolve well after the credential behind them can
have been replaced, and cancelling the previous task does not settle it:
a request that already came back races the cancellation and installs the
previous person's private videos over the purge that was meant to remove
them. Popular and trending stay unfenced — they are unauthenticated, and
discarding them on a change of login would cost a fetch for nothing.

Discarding the account-scoped content now also forgets how far the feed
had been read. The high-water mark belongs to the feed that was thrown
away; left behind, it gates pagination against a page the next login
never loaded, and that login cannot ask for a second page until its
first exceeds a count it knows nothing about.

360b1ec0cb Fence the last in-flight paths across an account change
A home-feed disk load that was already suspended when the context or
Apple account moved no longer installs what it brings back: the
in-memory cache is empty by then, so the purge finds nothing to drop and
the previous login's private feeds would quietly reappear.

Instance-browser pagination carries the login it was requested for, so a
page still in flight cannot be appended to the next account's feed, and
the pagination state is reset with the content it belongs to.

The stateless-server refresh stops before touching anything when its
result is stale, rather than only rejecting the videos and going on to
set loading state and start polling for subscriptions nobody is showing.

Signing in re-resolves its target first. The round trip leaves room for
another device to delete the account, and the credential would have been
filed under one that no longer exists — reported as success. A
provisional account is rolled back when its backend cannot be resolved
at all, which is what a vanished instance looks like.

9a93b0347e Tell the views when a credential is replaced
Signing in again as a different person on the same server changes
neither the account ID, the context, nor usually the status — so nothing
the views observe moved, and the previous user's subscriptions and feed
stayed on screen while actions went out under the new credential. There
is now a notification for exactly that, and the subscriptions view and
the instance browser discard and reload on it.

An account deleted after its instance disappeared retires its legacy
Keychain item too. Identifying that item needs the instance, but
checking it does not: the adoption marker is specific to service,
account, scope and the exact secret, so asking both managers retires it
if either owns it and does nothing otherwise.

1c0a3e8e9a Keep one login's verdicts and content off another's
A feed failure recorded its verdict before checking whether anyone was
still waiting for it, and the verdict resolves the *currently* selected
account — so a 401 from a credential the app had already moved off could
mark its replacement, or a different account, as rejected indefinitely.

The instance browser drops its feed, subscriptions and playlists when
the selected login changes. Nothing else there would notice: the
instance, the tab and the "already has data" shortcut are all unchanged
between two accounts on the same server.

Caches are no longer discarded while the identity is unresolved. With
iCloud Drive off the scope drops to unresolved on every activation and
comes back the same, and the context reads as local in between — which
looked like a move and threw the caches away several times a day.

Local is always in the account picker again. Its feed needs a Yattee
Server and reports that itself; with correction no longer moving away
from local, leaving it out of the list made it unreachable once left.
And the subscriptions view reloads when an instance is switched off,
which moves reads to local without touching the context or any status.

6a2b3250ce Remember credential and instance deletions across launches
The credential digests are persisted. A login replaced on another device
while this one was not running left the Apple account, the context and
the status all unchanged, so nothing noticed on the next launch that the
cached feed belonged to whoever was signed in before.

Deleting an instance is remembered too. Its accounts may still be in
transit — CloudKit and the instance list travel separately — and one
arriving afterwards was installed as a permanent orphan, credential and
account record intact, with no screen yet that could remove it. Late
arrivals are now deleted like the rest.

The source editor and the instance browser recompute their signed-in
state when a status changes, not only when the account list does: a
credential arriving over iCloud Keychain moves nothing else, and the
authenticated imports and the Feed tab stayed hidden until the view was
rebuilt.

e1ebb71511 Bind results to the account and identity they were requested for
Fetched account records are staged under the identity the fetch began
under, not whichever is current when they arrive — the engine's fetch
spans several delegate events and the Apple account can move between
them, which would have filed one identity's accounts under another's.

Subscription fetches are fenced against context switches, not only
against a provider being discarded. Providers are deliberately kept
across a switch — each is one account's cache — so an earlier account's
fetch could finish afterwards and put its channels on screen while
unsubscribes went to the account now selected.

The subscriptions view reloads when the *effective* context moves, which
a credential arriving, expiring or being rejected does without the
stored context changing at all.

Feed requests report what they learn about the account, like every other
authenticated call: a credential that expired during a feed-only refresh
kept looking signed in, and the fallback never engaged. The
classification behind that verdict now exists once, on AccountsManager,
rather than in each provider.

e094770047 Fence the last two caches and undo failed logins properly
Home feeds and subscription providers join the subscriptions feed in
dropping results that belong to a login the app has since moved off.
Clearing a cache does not cancel what is already awaiting the server,
and an Apple-account switch discarded providers without invalidating the
fetches holding them.

A sign-in whose credential the Keychain refused to store is now rolled
back rather than deleted. Creating an account also queues the permanent
marker that stops every other device synthesizing an account for that
instance's pre-revamp login; leaving it behind would suppress a still
valid legacy login everywhere on the strength of an account nobody has.
An account the server already confirmed is still deleted properly,
tombstone and all.

Caches with no recorded owner are discarded even when the identity
cannot be resolved at all — that is the same first launch after
upgrading, only offline.

An account whose credential is missing no longer hides a signed-in
sibling on the same instance, which made the whole instance report
itself as logged out. And connectivity returning recomputes statuses, so
an account marked unreachable retries instead of waiting for a
foreground transition it has no way to cause.

b07af6c153 Separate account status from the account list, and stop stranding accounts
Recomputing statuses reads the Keychain, which cannot know that a server
rejected a credential or failed to answer — and it ran in reaction to
the same notification those verdicts were announced with, so it erased
them as they were recorded. Status changes now have their own
notification. With that separation `unreachable` no longer has to be
preserved to survive: it is transient, and preserving it stopped every
read from reaching the server, so nothing would ever discover that the
network had come back.

A fetch already running when its provider is discarded now has its
result dropped. Signing in again — or switching Apple account — changes
neither the context nor the account ID, so the previous login's channels
would otherwise arrive as the current account's.

Caches with no recorded owner are discarded rather than adopted. The
first launch after upgrading finds feeds written before anyone recorded
whose they were, and the Apple account may have changed since.

The legacy validator's auto-correction moves the data context with it,
and Manage Channels reloads on the context rather than the legacy value
— it could list one account's channels while unsubscribes went to
another.

cc0fd3e6f4 Fence stale feed results and stop guessing at unknown account state
Signing in again keeps the account ID and the context, so a request
already in flight under the previous credential could land afterwards
and write that user's private feed back into the cache and onto disk.
Feed results now carry the account they were requested for and are
dropped if it has moved.

An account with no recorded status was reported as "sign in required".
While the identity scope is unresolved nothing can read the Keychain
under the right scope, so that is the absence of an answer, not one — on
a tokenless or first-seen Apple account it told users with working
logins to sign in again and dropped reads to local data. It is now a
state of its own.

Transport failures mark the account unreachable instead of leaving it
"signed in", which is what the documented local read fallback keys on.
Neither that nor a rejection is overwritten by the Keychain-based
refresh any more: only the server can clear what the server said.

Disabling sync deliberately does not rewrite Keychain items to local.
That means deleting them, and deleting a synchronizable item propagates
to every device — "stop syncing this login" would sign the user out
elsewhere, which is not what the toggle says. The reasoning is recorded
at the call site.

b37ca40d37 Settle account ties and stop discarding caches on every launch
Two devices editing an account in the same instant — or migrating one,
since every migrated account is stamped at the epoch — each kept its own
label and considered the matter closed. Equal timestamps are now broken
by the label, on the incoming side and in the conflict resolver alike,
the same rule the context already uses.

Cached feeds were thrown away on every ordinary launch: recomputing
statuses posts a notification, and the observer ran before the value it
compares against had been seeded. The seed now happens first.

Cache ownership is checked once at launch and compared against a
recorded owner afterwards. An unresolved identity at launch means the
owner cannot be established at all — a switch to an unseen Apple account
while offline looks exactly like that — so the caches are discarded;
mid-session it is a transient, and with iCloud Drive off it happens on
every activation, so it no longer clears anything.

Whether a Keychain item syncs is fixed when it is written, so a login
stored while sync was off stayed on this device while its account record
travelled, leaving every other device with an account whose credential
never arrives. Turning sync on rewrites them.

Reseeding a deleted zone marks the account records dirty even while the
category is off, so re-enabling it restores them instead of finding an
empty outbox.

ae2fee2d4c Make a second login on an instance reachable and orderable
An additional login could be created but never selected: the legacy
picker lists one entry per instance and always resolved to whichever
account signed in first. Account rows gain a "Use This Account" action,
and the subscriptions view reloads on the data context rather than on
the legacy setting — two logins on the same instance map onto the same
legacy value, so switching between them changed nothing on screen while
writes went to the other account.

Two devices migrating different legacy selections produced contexts with
identical epoch timestamps, and each refused the other's: a permanent,
silent divergence that both sides considered settled. Equal timestamps
are now broken by the selected account's ID, on the incoming side and in
the conflict resolver alike — a record that wins the upload must not be
refused on arrival.

Credential cleanup falls back to both managers whenever the backend
cannot be resolved, not only when the account is unknown here: an
instance deletion can arrive before the tombstone, and the credential
was then left in the Keychain.

4f617b52e1 Stop a status refresh from erasing a rejected credential
The API layer marking an account `credentialRejected` posts the same
notification that recomputes statuses, which saw the Keychain item still
present and immediately reported "signed in" again. The rejection could
therefore never survive the moment it was recorded, and the user was
never asked to sign in again. Only the server can clear a rejection now;
storing a new credential resets it explicitly.

Cache invalidation follows the effective context rather than the stored
one. A credential arriving or disappearing flips reads between the
account and local without the stored context moving, so the global feed
caches kept whichever side had populated them.

The login sheet stays open when the credential could not be stored — an
unresolved identity scope or a Keychain failure — instead of dismissing
and discarding what the user typed.

923e13565f Stop a fresh login from synthesizing a phantom migrated account
Signing in wrote `usesAccountLogin`, which syncs through key-value
storage independently of the account records. A device receiving that
flag before the account synthesized a migrated account for a login that
was never legacy — and the marker arriving later deliberately retracts
nothing, so the credential-less duplicate was permanent and uploaded.
The flag is pre-revamp state that migration only reads; accounts
describe logins now. `needsCredentials` reads the account list for any
instance that has one, so the badge it drives is unaffected.

A tombstone now dominates contexts as well as accounts: an offline
device can select an account another device deleted and publish that
choice with a newer timestamp, which would have left every device
pointing at an account that is never coming back.

Cached private feeds survived an Apple-account switch two ways. A scope
this device has seen before resolves while `CredentialIdentityScope` is
still being constructed, so the change notification fires before any
observer exists — startup now compares the persisted cache owner. And a
purge asked for before the disk cache is read was undone by the load,
which now carries it.

The need to re-bootstrap after dropping records for want of a resolved
identity is persisted. The engine may already have moved its token past
those records, so a launch that lost the in-memory flag would neither
replay nor bootstrap them.

ff78cc0121 Make synced accounts usable the moment they arrive
A fresh device never adopted the synced context. The local value is a
default stamped when the manager is built, so it is always newer than a
choice made on another device, and ordering against it discarded that
choice. With no local decision to protect, the first synced context is
simply adopted.

An account arriving mid-session sat at "sign in required" until the app
was relaunched: nothing recomputed its status once the metadata — or its
instance — turned up, even when iCloud Keychain had already delivered
the credential. Both arrivals now recompute statuses and re-run the
legacy mirror, which was similarly stuck whenever the instance had not
arrived yet.

Signing in again keeps the same account and the same context, so nothing
downstream saw a change — but the credential may now belong to somebody
else, and their subscriptions and feed stayed on screen. The provider
and the account's caches are discarded on every credential replacement.

The deletion repair also cancels a context upload the deleted choice had
queued; sending it would have published the fallback under that choice's
timestamp, which not stamping it "now" exists to prevent.

Piped subscribe/unsubscribe and Invidious unsubscribe now report their
outcome like every other authenticated call, so a credential rejected by
one of them stops claiming to be signed in. Removing the last account
updates the source screen, which kept offering authenticated imports
that could only fail.

7c966b18a9 Keep deleted credentials and cached feeds from outliving their account
A deletion can reach a device before the account it deletes does — the
tombstone and the account are separate records, and iCloud Keychain runs
on its own timeline — and the credential cleanup was skipped whenever
the account was unknown here. The scoped key needs only the account ID,
so both credential managers are now asked to drop it; the unscoped
legacy item still needs the instance and is left alone.

Cached data is invalidated on the data context rather than on the legacy
selection it maps to. Two logins on the same instance collapse onto the
same legacy value, so switching between them cleared nothing and the
subscriptions feed kept showing the previous account's videos. Home
feeds are keyed by instance alone and had the same hole across accounts
and across Apple accounts; they are dropped with it.

The third source-deletion path now cascades to accounts like the other
two, and the Invidious private-playlist lookup resolves its session
through the account — a login created after the revamp writes only an
account-scoped credential, so the instance-keyed lookup missed it and
fell through to the public endpoint.

d366982ad8 Close account lifecycle gaps found in review
A synced context change had no effect on the pre-revamp
`subscriptionAccount` setting several views still read, nor on the feed
cache, which is global rather than account-keyed — so a selection made
on another device left this one showing the previous account's
subscriptions and videos. Both now follow every context change,
whoever made it.

Instances replaced wholesale by iCloud bypassed `saveInstances()` and so
posted no change notification. A legacy authenticated instance arriving
that way never reached account migration: no account row, and no action
to adopt its saved login, until an unrelated edit or a relaunch.

Deleting an instance now deletes the accounts on it, while the instance
is still resolvable — afterwards the account's credential manager cannot
be determined from its type and the credential would be stranded. Only
an explicit deletion cascades; an instance vanishing from iCloud leaves
its accounts orphaned, because absence is not a deletion.

A context whose instance has been switched off is temporarily
unavailable rather than valid. The account stays signed in, so nothing
about the account said the server had been turned off, and requests kept
going to it while the switcher already hid it.

0c003c71cc Sync accounts through CloudKit records
A login created after the revamp got a random account UUID that never
left the device, so its credential was keyed to an ID no other device
had and the login was unusable there. Migrated accounts were fine only
because their ID is deterministically the instance ID.

Accounts, the permanent legacy-migration markers, the permanent deletion
tombstones and the selected data context now ride the existing
CKSyncEngine as four record types, with the rules the category needs:

- Absence proves nothing. A fetch resumes from a change token and never
  enumerates the zone, so deletions are records of their own and they
  dominate the account wherever they are seen — including the engine's
  retry-as-insert path, which is how a queued offline edit would
  otherwise resurrect a deleted account.
- Fetched records are staged durably before each delegate event returns
  and applied as a set, tombstones first, gated on the zone's own result
  rather than didFetchChanges, which fires after failed fetches too.
- Nothing activates for an identity that has not bootstrapped: a device
  left on the previous release consumed these record types as unknown
  and advanced its token past them, so each identity fetches the zone
  once from a nil token, outside the engine's own token.
- A disabled category defers records rather than discarding them; every
  persisted artifact is namespaced by identity, and async work is
  generation-checked so a fetch begun under one Apple account can never
  land in another's state.
- Uploads are ordered: a marker never outruns the account it describes,
  and a context naming an account is never published before that account
  is server-confirmed.

bef119f70e Resolve contexts and credentials through real accounts
Round two of review on the accounts layer.

The settings picker mapped its legacy instance-keyed selection straight
onto DataContext(legacy:), which turns an instance UUID into an account
UUID. That identity only holds for migrated accounts - a login created
after the revamp has a random ID - so selecting a freshly added account
named one that does not exist and left the provider nil. Selections now
resolve through AccountsManager to an actual account on that instance,
preferring a signed-in one. The picker still lists one entry per instance
and so cannot show a second login; the Phase 3 switcher replaces it.

BackgroundFeedRefresher was missed in the previous sweep because it
resolves credentials differently: it routed on the legacy setting and
looked up "first enabled Invidious instance" with an instance-keyed
credential. After any new-style login that silently found nothing and
skipped the refresh. It now routes on the selected context and takes the
credential from that account.

Subscription reads used the raw stored context, so an account waiting on
its instance or credential rendered empty instead of falling back to local
data as the tri-state design specifies. Reads go through the validator's
effective context; writes deliberately do not, so a subscribe fails
visibly rather than landing in local data the user did not choose.

Account statuses are cleared when the identity namespace reloads, but
nothing recomputed them once a deferred scope resolution succeeded - a
synced account kept showing "sign in required" until relaunch. The scope
change now triggers a refresh, deferred by one turn so it cannot depend on
observer registration order relative to the store's own reload.

2fded2e1dd Fix account defects found in review
Five findings against the accounts layer, all real.

A fresh login created a random-UUID account and then flipped
usesAccountLogin, which posts instancesDidChange and re-ran legacy
reconciliation immediately. That guard only looked for an account whose ID
equalled the instance ID, so it synthesized a second, credential-less
account alongside the real one. Signing in now marks the instance migrated,
and reconciliation treats any account on an instance as evidence its login
is already represented.

save() set hasStoredContext, so the save inside reconcileLegacyAccounts
marked the still-default .local context as explicitly chosen and the
legacy-context migration that ran immediately after did nothing. Upgrading
users with a selected server account silently lost it. Only setContext,
applySyncedContext and the migration itself record a choice now.

An Apple Account change re-resolved the credential scope but never told
AccountsManager to reload its identity-namespaced storage - the only reload
was a one-time launch task - so the previous identity's accounts, context
and outbox stayed live under the new one, as did cached per-account
subscription providers. The scope now posts when its resolved value
changes; the accounts store reloads and the provider cache is dropped.

Fourteen call sites still read the pre-revamp instance-keyed Keychain item,
which a new login no longer writes: reopening the source screen showed the
account as signed out, and feed, browse, home and import operations treated
it as unauthenticated. They now resolve the credential through the account
layer, preferring the selected context's account and otherwise any
signed-in account on that instance.

Signing in while the identity scope was still unresolved created the
account in a temporary namespace that reloadForCurrentIdentity later
discards, while credential storage silently refused the write and the UI
reported success. Login is gated on a resolved scope and verifies the
credential actually stored before reporting success, rolling back a
newly-created account if it did not.

9065234606 Key subscription providers by account rather than backend type
SubscriptionService held one provider per backend and each resolved its
instance from settingsManager.subscriptionAccount, falling back to "the
first enabled Invidious instance" when that was unset. With several logins
possible on one instance that model breaks twice: two accounts would share
a single in-memory subscription cache, and the fallback could send an
account's request to a server it holds no credential for.

Providers are now built per account and cached by account ID, and each
resolves its instance and credential from the account it was built for -
no fallback. The protocol's accountType becomes a DataContext, which is
what actually identifies a provider now.

Views that branched on "is the subscription account local" read the context
instead, and the settings picker writes both stores. Keeping the legacy
setting in step is deliberate for now: several views still read it, and
letting the two diverge would show one account in the UI while serving
another's data. The Phase 3 switcher removes the last readers.

Signing out discards the account's provider so its cached subscriptions
cannot be served after the account is gone.

66f721e3ac Add Account model, AccountsManager and multi-login UI
Yattee 2 could hold at most one login per instance: a Keychain item keyed by
the instance UUID and a Bool on the instance. This adds the account layer
the rest of the revamp builds on.

DataContext (.local or .account) replaces SubscriptionAccount as the thing
that selects a data set. The legacy value maps onto it as an identity
mapping, because migrated accounts deliberately reuse their instance UUID.
Contexts carry an app-managed changedAt, and a migrated one is stamped at
the epoch so any explicit choice on any device outranks it whatever order
they arrive in.

AccountCapabilities makes what a backend supports a single switch in
InstanceType.accountCapabilities, verified against each API surface -
Invidious has history and playlist privacy, Piped has neither. Call sites
ask for capabilities instead of switching on instance type, which is the
seam the planned per-user Yattee Server accounts land on.

AccountsManager owns accounts and the selected context, stored per identity
scope so a switch of Apple Account cannot show or upload the previous one's
list. Legacy single-logins become accounts through a repeatable
reconciliation rather than a one-shot at launch, because instances arrive
over iCloud whenever they arrive; a permanent marker set is what makes
re-running safe, since usesAccountLogin stays true on the instance forever
and would otherwise recreate a deliberately deleted account. A dirty-flag
outbox records what still needs uploading so an offline change survives a
crash. The legacy subscriptionAccount selection is migrated one way,
reading local defaults first and then the raw KVS value - the previous
release published that key to iCloud but never read it back, so on a fresh
install it exists only there.

DataContextValidator replaces SubscriptionAccountValidator, which corrected
any selection it could not immediately verify. That was safe when a context
was just "an instance I am logged into", but with credentials arriving
asynchronously it would discard the user's choice during a slow Keychain
sync. Validity is now tri-state: anything that might still resolve keeps
the selection and falls back to local for reads only, with server mutations
disabled rather than silently retargeted at local data; only an actual
deletion corrects the stored context.

EditSourceView's single log in/out pair becomes a list of accounts with
per-row status, sign-in-again and sign-out-and-remove, plus the explicit
"use saved login from this device" action - the one-tap adoption that
replaced automatic adoption after the Keychain provenance measurement. On
tvOS a credential-less account offers a local sign-in instead, since Apple
never syncs app Keychain items there and the state will not resolve on its
own.

InstanceLoginView now returns the identifier alongside the credential so
the caller can file it in the Keychain beside the secret, keeping login
identifiers out of synced metadata.

2d23820e14 Stop blind rollbacks in the Keychain delete paths
Fifth review pass, which prompted measuring whether SecItemDelete can be
conditioned on a value. It cannot: a delete issued with a deliberately
wrong kSecValueData still returns 0 and removes the item, so there is no
compare-and-delete and every check-then-delete is a race by construction.
That measurement decides both fixes here.

Adoption no longer rolls back its own write when the verification read
comes back empty. The rollback could only ever be a blind delete of
whatever occupied the key by then - including a credential synced from
another device in the gap - and it would propagate. Nothing is deleted; no
marker is written, so the account stays signed out and an ordinary sign-in
recovers it.

Legacy deletion re-reads immediately before deleting and aborts if the
value moved, shrinking the window to a single call gap and catching a
replacement that landed while the fingerprint was being computed. A
residual race remains and is documented at the call site: closing it is not
possible with these APIs, and never deleting would leave a credential the
user explicitly removed sitting in their iCloud Keychain.

The debug provenance report repeated the same nil-token ambiguity the scope
logic was fixed for, reporting "no Apple account signed in" when iCloud
Drive is merely off. It now reports the token as unavailable and shows
CloudKit's account status separately, so a re-run cannot draw a false
conclusion from it.

9fd0a71035 Add identity-scoped, account-keyed credential storage
Yattee 2 keys credentials by instance UUID with no notion of which Apple
account they belong to, and reads them back with SynchronizableAny. Apple
documents that Keychain data may stay on device when a user signs out and
chooses to keep it, so whoever signs in next would be served the previous
user's credential - guaranteed for migrated accounts, since local instances
survive the switch and the migrated account UUID is deterministically the
instance UUID.

Credentials are now keyed "<identityScope>|<accountID>", where the scope is
the CloudKit user record (identical across a user's devices, so iCloud
Keychain sync still works). Usernames get the same scope and live beside the
credential, keeping login identifiers out of synced metadata.

The legacy unscoped item is never adopted automatically. A strict
kSecAttrSynchronizable == true query was the candidate discriminator for
"this secret belongs to the current Apple account", but measured on iPadOS
27.0 a retained item keeps the attribute and still matches that query with
no Apple account signed in at all - the flag records what was once requested,
not live iCloud Keychain membership. Reads therefore never fall back to the
legacy key; adoption is an explicit user action that copies the item,
verifies the scoped read-back, then records a marker bound to the identity
and a salted fingerprint of the secret. The legacy item is retained, because
deleting a synchronizable item propagates and would log out devices still on
the previous release mid-rollout. Deleting it later needs all three of: a
marker on this device, matching identity, and the item still holding the
adopted secret.

The instance-keyed path is untouched, so no shipping call site changes
behavior. BasicAuthCredentialsManager stays instance-keyed - proxy auth
belongs to the instance, not to a user account.

While the scope is unresolved (first launch under a new Apple account,
CloudKit unreachable) reads report "can't tell yet" via isScopeResolved
rather than "signed out", and writes are refused rather than guessing a
scope. Login state is cached per scope so one identity's cache can never
answer for another.

Also adds the debug-only harness the measurement was taken with, under
Advanced > Developer > Experiments.

d624a09335 Fix timed links resuming at watch position instead of URL timestamp
Timed links arrive wrapped as yattee://open?url=... from the share
extension, but the timestamp was parsed from the wrapper URL, where a
single-? form like youtu.be/ID?t=N hides t inside the url query item.
With no startTime the player fell back to saved watch progress.

- Add URLRouter.unwrapped(_:) resolving the wrapper to the inner URL
  (raw remainder after ?url=, since the share extension does not encode
  & and URLComponents would drop &t= parts) and use it in handleDeepLink
- Thread forceStartTime through openVideo/playPreferringDownloaded/play
  so explicit link timestamps beat the 90%-watched restart threshold,
  clamped to just before the end; resume flows keep the old behavior
- Carry the parsed timestamp through OpenLinkSheet's play action, which
  dropped it entirely
- Cover timestamp parsing and wrapper unwrapping in NavigationTests

d17423fa5b Fix autoplay countdown showing in repeat one queue mode
When queue mode was set to repeat one, the "Playing in N seconds"
countdown still appeared after a video ended, showing the next queued
video - then restarting the current one anyway. The video-end path
never consulted the queue mode; only playNext() did, after the
countdown had already run.

- PlayerService.backendDidFinishPlaying: restart immediately in repeat
  one mode, regardless of queue contents, player visibility, background,
  or PiP. This also fixes repeat one never looping with an empty queue.
- ExpandedPlayerSheet.isAutoPlayEnabled: false in repeat one mode, which
  gates all countdown triggers (start on ended, overlay render, re-arm
  on appear) on iOS/macOS.
- TVPlayerView.handleVideoEnded: early-return in repeat one mode so
  tvOS shows neither the countdown nor the replay controls.

908a916f76 Fix sending extracted videos (Twitch streams) to other devices
The remote control loadVideo command only carried the raw video ID and
an instance URL, so extracted videos (Twitch live streams and other
yt-dlp sites) failed on the receiver: it tried to fetch the ID from the
/api/v1/videos endpoint, which rejects non-YouTube IDs.

The command now carries the full ContentSource and title. The receiver
rebuilds the VideoID from the source and opens a placeholder Video -
the player then re-extracts streams and full metadata from the original
URL, same as when opening the video locally. Media-source extractors
(WebDAV/SMB/local) keep using the existing UUID:path branch.

Both fields are optional for protocol compatibility: old receivers
ignore them, commands from old senders keep the legacy behavior.

Also stop sending a start time for live streams - there is no shared
timeline, the receiver joins at the live edge.

2c0c2e853a Apply thumbnail fallback everywhere a single URL was rendered
The previous fix rebuilt the quality chain when converting persisted
models back to videos, but many consumers discarded it again by
rendering bestThumbnail (usually a maxresdefault.jpg that 404s for
older videos) as a single URL with no fallback.

Extract the retry logic from VideoThumbnailView into FallbackLazyImage
and use it at every in-app site that can iterate: player thumbnails
(mini bar, expanded sheet loaders, autoplay previews, tvOS audio-mode
artwork - previously a silent black screen), video info card and tvOS
header, and the tvOS playlist cover.

Sites that fetch or send exactly one URL are rewritten to the
always-available hqdefault variant via Thumbnail.reliableURL (exposed
as Video.reliableThumbnailURL): Now Playing artwork, Top Shelf
snapshots, remote control state, the frozen transition thumbnail,
blurred info background, navigation covers, and playlist covers
derived from a video's first thumbnail in Invidious/Yattee Server
responses.

Also invert RecentPlaylist's upgrade helper, which rewrote covers *to*
maxresdefault, walk the quality chain when caching download thumbnails
for offline artwork instead of giving up after one 404, and expand the
remaining single-thumbnail Piped conversions into full chains.

aa6e7fbce9 Stop tracking resume progress for live streams
With "Partially Watched Videos" set to Ask, opening a live stream showed
the resume sheet with a playback timestamp. A live position is relative
to the live edge, not a fixed timeline, so it is meaningless as a
playhead.

Live views are still recorded in history, but carry no resume position:

- WatchEntry gains a persisted isLive flag plus recordLiveWatch(), which
  stores no position and clears state a drifting HLS duration may have
  left behind. progress is always 0 and toVideo() propagates the flag so
  history rows render the LIVE badge.
- from(video:) clamps duration, keeping Piped's -1 live sentinel out of
  storage.
- DataManager routes live saves through recordLiveWatch() and clears the
  flag on the non-live path (before updateProgress, so the auto-finish
  check is not suppressed by the hard-0 live progress), letting an entry
  heal once the stream becomes a VOD.
- PlayerService skips completion saves, always starts at the live edge,
  and drops any startTime passed for a live video.
- The resume prompt, the "Continue at" button label, thumbnail progress
  bars, "X remaining", Continue Watching and tvOS Top Shelf all exclude
  live entries.
- CloudKit syncs isLive with the rest of the watch state: the conflict
  resolver carries it with watchedSeconds/isFinished and the sync engine
  applies it when merging into an existing entry. It is read leniently,
  so the schema version stays at 2 and older clients keep parsing these
  records.

6a0fe2fbbf Show and label WebDAV/SMB video streams in the quality selector
Media-source streams from WebDAV/SMB were invisible in the Video list:
the filter required remote URLs to carry a resolution, which
MediaFile.toStream never sets. Include non-adaptive remote streams
without resolution (only media sources produce those), extend the
mpv-track display enrichment to the currently playing stream regardless
of URL scheme, and classify metadata-less streams as recommended — a
nil codec previously counted as software-decoded, hiding the row behind
advanced mode with a spurious warning. The warning now uses the
enriched codec.

9e546e29ee Label local-file video quality from mpv track info instead of Unknown
Streams built for local folder files carry no resolution/codec/fps
metadata (unknowable before demux), so the quality selector labeled
them "Unknown". Use the video track mpv reports (demux-w/h/fps, codec)
to fill those fields into a display-only copy of the stream — the
Video row and summary now show e.g. "720p · 30fps" with a codec badge.
Selection and tap handling keep using the original stream.

67ed8c322b Add embedded audio/subtitle track selection for multi-track files
Files with multiple embedded tracks (e.g. MKV from media sources or
downloads) previously exposed none of them: mpv's track-list was never
read, aid was never set, and sid was only ever no/auto. The quality
selector showed no Audio or Subtitles tab for such files.

MPVClient now observes track-list/aid/sid and delivers a coalesced,
leniently decoded [MPVTrack] snapshot; selection state is derived from
the reported "selected" flags. Embedded tracks are switched live via
aid/sid (no reload), surfaced in the existing Audio/Subtitles sections
alongside external captions on iOS, tvOS and macOS. External sub-add/
audio-add tracks are filtered out to avoid double-listing. User picks
are sticky across same-video reloads (quality switch, audio mode,
retries) and preferred audio/subtitle languages auto-select a matching
embedded track once per load, with external captions taking precedence.

150ebf42a4 Fix #955: make subtitle appearance settings adjustable on tvOS
Text color, border color, background color, border size, and bottom
margin were rendered as static rows on tvOS (ColorPicker and Slider are
unavailable there), so the focus engine skipped over them and they could
never be changed.

Replace them with menu pickers following the existing font size pattern:
- Text/border/background color: 9 preset colors with a swatch in the
  row label; stored values snap to the nearest preset
- Background opacity: 25-100% steps (iOS parity, where ColorPicker
  supports opacity for the background)
- Border size: 0.0-5.0 in 0.5 steps
- Bottom margin: 0-50% in 5% steps

Verified on tvOS simulator: rows are focusable, selections persist and
are rendered by MPV during playback.

cd01c08b5a Fix #960: scope subscription counts, import/export to active account
When an Invidious/Piped account is active, several views read the local
SwiftData subscription store instead of the account, so counts
contradicted each other (Home tile said 10 while the Channels list
showed the server's 2):

- Home Channels tile now uses the provider's count via new
  SubscriptionService.cachedSubscriptionCount (fetched once in the
  background when the server cache isn't populated yet)
- Export footer and export content use the active account's list;
  export runs async with a spinner and surfaces fetch errors as a toast
- CSV/OPML import routes through SubscriptionService.importSubscriptions,
  subscribing on the server for server accounts instead of silently
  writing to the invisible local store
- ChannelView subscribe-state is corrected via the provider after the
  optimistic local-store read; unused *Sync write helpers removed
- Server-account subscribe/unsubscribe/import now post
  subscriptionsDidChange so other views refresh
- New "Delete Local Subscription Data" section in Subscriptions
  settings (visible with a server account) clears the local store and
  queues CloudKit deletions so iCloud doesn't restore it

  basic auth credentials (auth is always required for this type)
- Persist usesBasicAuth/usesAccountLogin flags on Instance (synced via

  too; maintained on credential save/delete, login/logout, and legacy
  migration
