Sign-out never cleared local storage. It stopped push, flushed settings and
removed the subscription -- that last one reasoned explicitly that a browser
left holding someone's mail becomes somebody else's next -- and then left the
settings cache and the recently-addressed list on disk. That list is other
people's addresses, and nothing ever removed it.
Clearing it on sign-out is now unconditional, because lending a laptop is the
same exposure as a public machine, only quieter. The keep-list is short and
deliberate: lastUser, which only a trusted device writes; the trust flag; and
the random push device id. Everything else goes, so a key added later is
forgotten by default rather than by nobody having thought about it.
"Keep me signed in on this device" defaulted to true, which assumed the answer
most costly to get wrong -- someone on a library machine got a thirty-day
cookie unless they noticed a ticked box. It now asks whose computer this is,
defaults to not yours, and says what each answer does. Untrusted means a
session cookie, nothing written locally, no push subscription, and a five
minute idle sign-out.
The idle timer is there because the alternative does not work: custom
beforeunload text was removed from browsers years ago, and no event fires at
all for walking away from a signed-in screen, which is the case that matters.
A timer needs nobody's cooperation.
Reads are gated as well as writes, since a machine trusted once still has the
residue; an untrusted sign-in purges it outright. The wire keeps calling this
`remember` -- it is persisted in SESSION_FILE, and renaming it would invalidate
every session file on upgrade for a change of vocabulary.
Verified in a browser against the mock, not only in tests: untrusted sign-in
leaves localStorage empty through a full session including folder expansion;
trusted writes settings, recent and lastUser as before; sign-out clears recent
and settings while keeping lastUser; an untrusted sign-in afterwards clears
even that.
The roadmap's preamble promised that anything with an issue number was tracked
in the issue tracker, and the two-factor entry ended in a bare "Reported as
#75". That issue was closed as completed on 2026-08-26, so the one entry the
promise applied to was the one it was wrong about: a reader following the link
finds a closed ticket and has to guess whether the work went with it.
It did not. #75 reported a sign-in refused with nothing but "Invalid
credentials", and that bug was fixed -- the message now says what is happening
and points at app passwords. The OAuth work the report uncovered stayed behind
on this page, which is exactly the case the preamble had no room for.
So the preamble now says an issue number records where an entry came from
rather than where it is tracked, and the entry says plainly that #75 is closed,
what closing it fixed, and that there is no ticket to watch for the rest.
"Gmail-class webmail" describes the client, and every webmail says something
like it. What no other webmail for Stalwart says is that the container has
nothing to persist: one optional write path, and with IMMUTABLE=1 switched on,
no volume and no writable root filesystem at all.
The Gmail comparison still earns its place -- it is what tells someone what the
client feels like to use -- so it stays, one clause later, where it describes
the app rather than the product.
Holding the reload back while a compose window had unsaved text protected the
text, but it meant a tab could sit on a build the server no longer runs for as
long as someone left a draft open -- which is not automatic, and automatic is
the point.
So the reload is unconditional once the versions differ, and this will
sometimes take an unsent draft with it. The trade is deliberate: a tab talking
to a server it does not match is the worse failure, and it fails quietly.
Checking only on a 401 was not automatic, just deferred. It needs the tab to
make a request, so one left open and idle went on running the old build until
somebody touched it -- which is exactly the thing that cannot be relied on.
The obvious signal turned out to be the wrong one, and testing is what showed
it. A deploy kills the EventSource behind /api/events, which looks like the
perfect cue, except it arrives while the container is still being replaced: the
check that follows cannot reach the server, fails, and is never retried.
Waiting for the stream to come back instead does not work either, because the
session died with the old container, so the reconnect is answered with a 401
and never reaches "connected" at all. The drop is still watched, since it costs
nothing and sometimes lands late enough to be useful, but nothing depends on it.
What the guarantee rests on is a slow poll while the tab is visible, plus a
check when it becomes visible again. Neither cares what the stream is doing or
whether anyone is at the keyboard. /api/health touches nothing upstream, so a
minute between checks costs one small request per open tab.
Reloading is now something that happens to people rather than something they
ask for, which makes it able to destroy work. A compose window holds text that
has not reached the server, and after a deploy it cannot be saved at all --
the session went with the container. Reloading would be the difference between
signing in again and pressing send, and losing what was written. So anything
holding such state can say so, and compose does; the tab stays on the old build
until the draft is dealt with, and catches up on the next check afterwards.
Being signed out and picking up a new version are separate things, and only
the first was happening. An immutable instance holds sessions in memory, so a
deploy signs everyone out -- but a 401 only swaps the view to the sign-in form,
client-side. The tab keeps the bundle it already has, and the old JavaScript
goes on talking to the new server until someone happens to reload by hand.
The pieces for fixing it were already there. index.html is served no-cache and
the assets under it are content-hashed and immutable, so a reload is all it
takes; Vite bakes the build's own version in as APP_VERSION; and /api/health
reports the server's. What was missing was something to compare them.
The check runs on a 401 rather than on a timer, which is the moment it matters
and costs one small request. It compares versions rather than reloading on
every 401, so an ordinary session expiry still lands on the sign-in form with
the page intact. And it runs before the sign-in form is shown rather than
after, because reloading a form someone has already started typing into would
throw the password away.
Failing to reach the server is not a reason to throw away what is on screen, so
anything other than a clear answer leaves the page alone. The version that was
reloaded for is remembered for the session, so a server that keeps reporting a
version the bundle does not match -- a stale proxy cache, a half-finished
deploy -- cannot put the tab in a reload loop.
IHASMAIL_IMMUTABLE=1 runs the container the way the README's "Running
immutably" section describes: read-only root filesystem, no volume, sessions
held in memory. Until now that shape could be run by hand but not deployed --
the run line mounted the data volume unconditionally, so a redeploy would have
quietly put a mutable container back.
The switch is one variable and nothing else. IMMUTABLE=1 is passed to the
server too, which checks the claim rather than believing it, so a half-applied
switch refuses to start instead of looking fine until the next redeploy signs
everyone out. SESSION_FILE is cleared with -e rather than by editing the
environment file, because -e wins over --env-file; that keeps going back a
matter of changing the same one variable:
IHASMAIL_IMMUTABLE=0 ./ihasmail-deploy.sh --yes
which reproduces the previous run line exactly. The named volume is never
touched in either mode, so the sessions that were in it when the switch was
thrown are still there to come back to.
The server writes to one path and no other: SESSION_FILE, from sessions.ts.
Everything else it touches on disk it only reads. So a container with a
read-only root filesystem already works -- except that `VOLUME ["/data"]`
quietly undid it. Docker acts on that directive: a container started without
`-v` gets an anonymous volume mounted there anyway, writable even under
`--read-only`. It persisted nothing across a redeploy, since each new container
got a fresh empty volume, and it left an orphan behind every time one was
replaced. Deployments that want the sessions to survive already say so
themselves -- docker-compose.yml and deploy.example.sh both mount a named
volume -- so removing the line changes nothing for them.
IMMUTABLE=1 asserts that this is how the instance is running. It is checked
rather than believed: the server refuses to start if SESSION_FILE is still set,
or if the filesystem it is installed on turns out to be writable. Left
unchecked the misconfiguration is silent, because persisting sessions is
best-effort -- a read-only /data costs one warning at the first sign-in and
nothing more until the instance is replaced and everyone is signed out.
SessionBackend names what the rest of the server asks of a session store, and
`sessions` in app.ts is typed as it. Nothing changes today; SessionStore is
still the only implementation. It is there so the OAuth work is written against
the interface rather than the class, and so the interface can record which of
its methods a stateless backend could satisfy alone: create, resolve, reseal
and destroy each touch one session, while listForUser and destroyAllForUser
have to reach sessions other than the caller's. The second of those carries the
guarantee that changing a password invalidates the sessions still holding the
old one, which is why it needs a registry -- Stalwart's token registry, once
sign-in goes through OAuth.
docs.ihasmail.org is where installing, configuring and using ihasmail
are explained, and nothing in the app pointed at it. The profile menu is
where someone looks for the things that are about the app rather than
about their mail, so it goes there, above Settings, and opens in a new
tab: reading the docs is something you do beside your mail, not instead
of it.
`MenuItem` renders a real anchor when given an href, rather than a button
calling window.open. The browser's own handling of a link comes with it --
middle-click, a modifier-click, "open in new tab", the address on hover,
copying it -- none of which a button offers however carefully it is
scripted, and all of which someone expects of a menu entry that leaves the
app. Items without an href are the button they always were.
It also needed a line of CSS. The global rule for `a` coloured and
underlined the one entry that is a link, so the menu had a blue underlined
item among four plain ones, which reads as a mistake rather than a
distinction.
Verified against the mock: the entry sits above Settings, is an anchor to
https://docs.ihasmail.org with target=_blank and rel=noopener noreferrer,
and computes to the same colour, size and decoration as Settings beside
it.
A folder id the account does not have rendered the ordinary empty state --
"Nothing here. This folder is empty." That is a claim about a folder that
is not there, so a stale link read as a folder that had emptied itself
rather than one that was gone (#111).
It now goes to the inbox and says why. Inbox is the kinder landing than a
dead end for a bookmark that has outlived its folder, but swapping one
folder for another without a word would be its own small lie, so it does
not do that either.
The condition worth writing a test around is not the unknown id, it is
the one guarding it. The folder list arrives after the first paint, so for
a moment *every* id is unknown, the right one included. Without that gate
this redirects on every cold load, from the folder the reader actually
asked for, and looks exactly like a flaky link -- a worse bug than the one
being fixed and a harder one to see. `isUnknownMailbox` is a small pure
function so that case can be pinned down rather than reasoned about.
Only ever reachable from outside the app, which is why it went unnoticed:
the sidebar links to ids that exist. A bookmark to a deleted folder, or a
folder link passed between accounts, is where it bites.
Verified against the mock: an unknown id lands on the inbox with the
message and a full list rather than an empty one, and a cold load straight
into a real folder stays in that folder with nothing said.
Closes#111.
The site says you can pick recipients by reading the address books rather
than remembering a name. It had no picture of that, and a claim nobody
can see is a claim nobody believes.
Taken from the composer step, where a composer is already open. The
obvious place was a step of its own later in the run, and that failed:
navigating back to the mail list after the run has been through Files
does not reliably render rows within any wait I was willing to give it.
Worth knowing rather than rediscovering -- the earlier inbox step goes to
the same route and is fine, so it is the state left behind, not the
route.
The shot ticks two people before firing, since a picker photographed
empty shows a list rather than a choice.
The filters step still times out waiting for its editor, as it did before
this change. Everything up to it is written; filters.jpg is whatever the
last successful run left. Still undiagnosed, and still not this.
Two things, one of them not what it looked like.
An organizer fixture was built from a real, routable address. Every other
fixture in the codebase uses example.org or example.com, and this
repository is public, so that one was a personal address sitting in
public source for no reason -- the test asserts roles and participation
status and never reads either value. It is [email protected] now.
The names were wrong in the other direction. Three fixtures across two
files said "John Ellis", which is not the maintainer's name; it is
John Coffey. Being a name rather than a routable address, it leaked
nothing, but it was simply incorrect, and incorrect in the sort of place
nobody rereads.
The address and the name are separate questions and got separate answers:
the address is fictional because it is an address, and the name is real
because it is right. A message from [email protected] signed John Coffey
is exactly what these tests mean.
Found while checking, at the maintainer's prompting, whether the repo
leaked anything about the host it runs on. It does not -- the nginx and
deploy files here are the generic examples they claim to be, and the real
ones live in a private repository.
One test built its organizer from a real, routable address and a real
name. Every other fixture in the codebase uses example.org or
example.com, and this repository is public, so the odd one out was a
personal address sitting in public source for no reason -- the test
asserts roles and participation status and never looks at either value.
Now [email protected], matching what the rest of the tests already use.
Found while checking, at the maintainer's prompting, whether the repo
leaked anything about the host it runs on. It does not: the nginx and
deploy files here are the generic examples they claim to be, and the real
ones live in a private repository. This was the only thing the search
turned up that was worth changing.
It was the one shot taken by hand, and it outlived two rewrites of the
view it was meant to show -- a picture of a single-pane file list, still
in the docs after the pane grew a folder tree beside it. Nothing was
wrong with the process except that there wasn't one.
The script takes it now, expanding the tree and opening a folder first,
since a screenshot of Files with nothing open is a screenshot of a list
rather than of a file manager.
Anything the docs show should come from the mock. Otherwise it describes
whatever the app looked like on the day somebody had a screenshot tool
open, which is how this one got three versions out of date without
anybody noticing.
The other shots in docs/screenshots are refreshed by the same run. The
filters step timed out waiting for its editor, so filters.jpg is the
older one; that shot is untouched by anything here and the failure is not
diagnosed, which is worth knowing before the next person runs this and
assumes they broke it.
The third store fetching everything by asking for nothing. Same cause as
the calendars and address books a commit ago: Stalwart does not return
`shareWith` unless a client names it, so mail folders never looked shared
either.
This one has a narrow but real consequence. Sharing a mail folder is
withdrawn, because Stalwart stores the share and never delivers it, and
the only way left to clear one already made is the "Stop sharing" entry
-- which appears only when a folder looks shared. Without the property it
never did. The escape hatch built for exactly that situation could not be
reached from the situation it was built for.
Found by looking for the rest of them rather than waiting for the next
report: `ids: null` with no `properties`, across the app. The others it
turned up -- Sieve scripts, identities, the vacation response, quotas,
participant identities, push subscriptions -- have no `shareWith` to
lose, so mailboxes were the last.
The mock hides it here as well now, so all three are honest.
Nothing was ever badged as shared, "Stop sharing" never appeared, and the
share dialog opened on "not shared with anyone yet" over live shares. The
sharing itself was fine. The client simply never learned about it.
Stalwart does not return `shareWith` unless a client names it. A
`Calendar/get` or `AddressBook/get` with no `properties` comes back
without the field at all -- not null, not empty, absent -- confirmed
against the live 0.16.19 on a calendar and an address book that really
were shared with another account. Omit the list and there is no
`shareWith`; name it and the sharee is right there.
Both stores fetched everything by asking for nothing, and got less than
they would have by asking. They name the properties now.
The dialog is the part worth dwelling on. It seeds itself from the
`shareWith` it was handed, so it has been showing an empty sharee list on
collections that were shared -- the one screen whose whole job is
managing sharing, and the one most confidently wrong about it. Someone
looking there to see who had access, or to take it away, was told there
was nobody.
Files never had this: `fileNodeProps` has named the property since file
sharing went in, for the same reason and after the same surprise. The two
stores that fetched with `ids: null` and no properties are the two that
were blind.
The mock now omits it the same way. One that hands `shareWith` over
unasked lets a client that never asks look correct everywhere except
against a real server, which is exactly how this got here.
Verified against that mock: sharing a calendar puts the sharee in the
store, badges the row, adds "Stop sharing", and the dialog lists them --
while a `Calendar/get` with no properties still comes back without the
field, so the mock is now failing the way the server does.
Revoking a share meant opening the share dialog, removing each person
from it in turn, and saving. That is the right tool for changing who has
access and the wrong one for withdrawing it altogether, which is the more
urgent of the two and the one someone is likely to want in a hurry.
Both now offer "Stop sharing" in the context menu, which clears the lot
after a confirmation saying how many people lose access. It appears only
when there is something to revoke, so the menu says whether a thing is
shared as well as offering to change it.
A calendar also says it is shared now. Address books have carried that
badge since they gained sharing; calendars never did, so the only way to
find out was to open the dialog and look -- which for the owner of a
dozen calendars means opening a dozen dialogs.
Both go through the existing update paths, so a server that refuses is
reported rather than swallowed.
Verified against the mock, both kinds: sharing one shows the badge and
adds the entry, confirming clears `shareWith`, the badge goes, and the
entry disappears with it since there is no longer anything to stop.
The picker opened on "No contacts in this address book" -- about an
address book with contacts in it. Nothing was wrong with the button, and
that is why it read as one: it opened, correctly, onto nothing.
Contacts are fetched on demand. `loadAll` runs when the Contacts view
mounts, and `suggest` kicks it off itself, which is why autocomplete has
always worked from anywhere. The picker did neither, so opening a
composer without having visited Contacts first -- which is most of the
time, and every time in a fresh tab -- showed an empty list over a full
account. Anyone who had been to Contacts that session saw it work, which
is the sort of difference that reads as browser-specific when it is not.
It asks for them now, and says it is loading rather than that there are
none.
While here: the picker decided which shared books to offer on
`isSubscribed` alone. Stalwart refuses that flag on a book shared
read-only, so those are recorded in settings instead -- for an address
book it is the *only* record -- and filtering on the server's flag left
every shared book out of the picker while the sidebar showed it. Both now
ask the same question.
Verified against the mock from a genuinely cold store -- cards emptied,
`loaded` false, opening the picker as the first thing that wants them:
eight rows, from the reader's own book and a shared one, where before
there were none.
The reading pane emptied and refilled when a thread was marked read. On
an HTML message that is a flash to the app's own background and out
again, which is what remained of #100 once the message view stopped
rebuilding its body.
`applyChanges` dropped `fullIds` for every email the server reported as
updated, so the next read would fetch it again. But the reading pane
renders only the emails it holds in full. Dropping one took the message
out of the open thread until the refetch at the end of the same function
put it back -- and marking as read causes exactly that, because the
server echoes our own change back as an update. The gap is a round trip,
which is why it is plainly visible against a real server.
Nothing is lost by keeping the copy. RFC 8621 makes every property of an
Email immutable except `keywords` and `mailboxIds` -- the id is derived
from the content, so a body cannot change beneath one -- and both are in
LIST_PROPS, which the refresh immediately below merges over the cached
copy. The eviction only ever cost the message its place in the thread.
On the evidence, since I got this wrong once already by trusting a
reproduction that did not exist. This is reasoned from the code and
matched against the reported symptom -- "the pane empties and comes
back", which is precisely what removing an email from the thread and
refetching it looks like. It is not backed by a local reproduction: the
mock never ran this path at all, because `Email/set` announced nothing
and `Email/changes` always answered empty. That is being fixed
separately, and it is why every check made here has been against a server
that never reported the change being made.
Two silences, and between them the whole change-reconciliation path was
untestable here.
`Email/set` never announced anything. A real server pushes a state change
after a set and the client acts on it -- `Email/changes`, then the store
deciding what to do with the answer. The mock said nothing, so that path
simply did not run.
And `Email/changes` returned three empty arrays whatever had happened. So
even when it was asked, the answer was that nothing had changed.
Together they meant every version of the mark-read code has been checked
against a server that never reported the change being made. That is how
#100 reached production, and why the fix for it could be verified in the
message view -- where the flicker partly was -- while whatever remains
stayed invisible, because the code that runs when the server answers back
has never run here at all.
The mock now records what each set created, updated and destroyed against
the state it happened in, answers `Email/changes` from that log, and
broadcasts afterwards the way Stalwart does.
This is a mock change on its own. It fixes nothing and is not meant to:
it makes a path testable that was not, which is the prerequisite for
finding what is left of #100 rather than guessing at it. I had a theory
about `fullIds` eviction and reverted it -- three attempts to reproduce
the symptom against this mock failed, which was itself the finding.
Marking a thread read redrew the message pane: the mail vanished and came
back, white to dark to white on an HTML message that brings its own
colours, half a second after the reader started reading it. Worst with
auto-mark set to "immediately", where it happens the moment the thread
opens (#100).
The pane was not re-mounting. The *body* was being thrown away and built
again, and the reason is one dependency.
`HtmlBody` writes the message into a shadow root in an effect, and that
effect had the click handler in its dependency list. The handler is a
`useCallback` over `onShowImages`, which the parent passed as an arrow
created inline, so it was a new function on every render -- and therefore
the effect ran on every render, and every render replaced the rendered
message with an identical one. Marking as read is exactly such a render:
the store hands back a new email object and the thread re-renders.
The listener now lives in its own effect. It is attached to the shadow
root rather than to the contents, which survives the rewriting anyway, so
a handler that changes identity costs a listener swap and nothing else.
`onShowImages` is stable now too, but the split is the fix: it is what
makes the body immune to the next handler that changes.
This also stops the quoted-text toggle collapsing. `setQuoteOpen(false)`
lives in the same effect and had been resetting on every render, so
expanding a quote and waiting for the timer put it away again.
Measured rather than watched, since a flicker is exactly the thing an eye
will agree with you about. Holding a node from inside the shadow root
across the transition, on the same three-message thread with the delay at
0: before, 21 childList mutations on the root and the held node detached
and replaced; after, no mutations at all and the same node still
attached. Clicking a blocked image still reveals remote images, which is
what the moved listener is for.
Closes#100.
"You are not allowed to modify this address book." That is Stalwart's
answer to a sharee subscribing to a book shared read-only, and it is a
fair one: `isSubscribed` lives on the collection rather than on the
reader, so adding one is a write to the *owner's* account. The identical
write on a shared calendar is accepted. The difference is the server's.
So the flag is still asked for first -- a preference the server holds is
one every client agrees about -- and when it is refused the answer goes
in the reader's own synced settings instead, as `addedShares`, keyed by
account and collection. Either record counts as added, and the rule has
a test of its own because three components ask the question and they
must not drift apart.
Two things about how this hid. The refusal arrives as a *successful*
response with the id in `notUpdated`, so the version that ignored it saw
nothing wrong and the button simply did nothing -- fixed a commit ago,
and it is what turned "the + does nothing in Firefox" into a sentence
from the server. And it cannot be seen from the owner's account at all,
where the write succeeds: it took two browsers signed in as two accounts
to find, which is why it survived every check made from one.
The mock refuses the same write for the same reason. One that accepted
it would have gone on agreeing with the belief that shipped.
Verified against it: adding the shared book is refused by the server,
recorded in settings, and the book moves to "Shared with me" with its
contacts reaching the To field; removing undoes all three; and it
survives a full page reload, which is the point of putting it where the
settings live rather than in this tab.
Adding a shared address book did nothing in one browser and worked in
another. The button was not broken; the refusal was invisible.
Subscribing is the one call in the app that writes to somebody else's
account, so it is the one a perfectly healthy server is entitled to say
no to -- and JMAP says no to a `/set` by answering successfully with the
object listed in `notUpdated`. Neither subscribe method looked. The
promise resolved, the code carried on, the re-read came back unchanged,
and the row stayed exactly where it was with nothing said.
Every other `/set` in this codebase reads `notUpdated` and raises. These
two were written without it, which is the whole defect: not a wrong
answer, an unread one.
Both now check it and say what the server said, which is the thing that
was missing -- whatever the underlying refusal turns out to be, it can be
read off the screen instead of guessed at from which browser was in
front of you.
Addressing a message worked only if you already knew the name you were
half-way through typing. Autocomplete answers "finish this for me"; there
was no answer to "who is there?", which is the question someone has when
they open a compose window and want the person from the team list whose
surname they cannot summon.
The To row now opens the address books -- from a button beside Cc and
Bcc, where someone thinking about recipients is already looking, and from
the To label itself for anyone who tries that first. Search across every
book or narrow to one, tick as many people as the message needs, and send
them to To, Cc or Bcc. Picking for a field that is hidden opens it, since
a Bcc dropped somewhere invisible is worse than no Bcc.
Every address is its own row rather than every person. Somebody with a
work address and a personal one is a choice the writer has to make, and a
picker that listed the card and quietly took the first address would be
making it for them.
Shared books are in it on the same footing as the reader's own -- that
being the point of having added them -- with the account named on each
row, so it is never a mystery whose list a name came from. Books that
have not been added contribute nothing, the same rule the To field
already follows.
Verified against the mock: the picker lists the reader's contacts and the
shared book's, each row naming its source; ticking one of each and
choosing Cc opens the Cc row with both in it.
An account linked for its files also offered its calendar and its address
book, and neither had been shared. That was not ihasmail inventing them:
asked about the other account, the live 0.16.19 returns every calendar
and every book it holds, each with full rights -- read, write, share,
delete, all true. There is nothing in the rights to tell "shared with me"
from "reachable at all", because the server does not distinguish them.
`isSubscribed` does, and it is the field JMAP has for exactly this: it
came back false on all of them. So a shared calendar or book is listed
under "Shared with me" once the reader has added it, and under "Available
to add" until then, with one button either way.
Nothing unsubscribed contributes anything. A calendar that has not been
added draws no events, and a book that has not been added lends no cards
to the To field -- which is the one that mattered most, since it is the
difference between offering a colleague's contacts and offering a
stranger's without anyone having asked.
The mock's shared calendar and address book now arrive unsubscribed, the
way the real server hands them over, so the adding is exercised rather
than skipped; and its `Calendar/set` and `AddressBook/set` route by
account, since subscribing to somebody else's is a write to their
account and the mock had nowhere to put it.
Verified against the mock: the shared calendar sits under "Available to
add" with no events in the grid, adding it moves it to "Shared with me"
and its events appear, removing it undoes both; and `suggest("katherine")`
finds nothing until the shared book is added, then finds her.
Three things from using it on two real accounts.
A calendar shared with you never appeared. Nothing was wrong with the
share -- the calendar had nowhere to be shown. Calendars loaded from one
account and one only, so the sharer's were reachable solely by switching
the whole app to their account, which is the door being closed below.
They now sit under "Shared with me" beside the reader's own, in their own
colour, with their events in the grid and a click to hide them like any
other calendar.
Their events go through `instancesIn`, the one funnel every view already
reads, so month, week, day and agenda got them without being touched.
Events and calendars from another account are keyed by account as well as
id, and hiding one is remembered under the same key: an id means nothing
outside the account holding it, and two accounts sharing an id is
ordinary rather than unlucky.
An account that shared nothing was listed in Files as though it had.
Every non-personal account was offered on the reasoning that its folders
could speak for themselves -- but an account whose *calendar* was shared
has no folders to speak with, and appeared as an invitation to open an
empty pane. Each is now asked for one file before being listed, and
silence is taken for an answer.
And the account switcher is gone from the profile menu. It existed to
reach what other people shared and was the wrong door: it moved the whole
app to somebody else's account, and since Stalwart advertises every
capability on a shared account, mail, calendar and contacts went with it
and were refused. Everything it was for is now in the module the share
belongs to, found without anyone needing to know an account was involved.
What this does not prove is that Stalwart delivers a calendar share at
all. The mock says the client handles one, which is the half that was
missing; whether the server behaves like address books, which work, or
like mail folders, which do not, needs the two accounts again.
