* fix(email): mark opened messages seen in one IMAP operation
* fix(email): collapse unread opens and ignore stale responses
* fix(email): send seen flags as an IMAP flag list
Wrap the authoritative \\Seen STORE operand in parentheses so strict IMAP servers such as GreenMail accept both cache-miss and cached-open transitions. Tighten the focused fake IMAP contract to reject the previously emitted bare flag atom.
* fix(email): guard stale authoritative opens
* fix(email): report a failed \Seen instead of withholding the message
The authoritative-open contract made a failed STORE fatal to the read: the
cold path raised after the body was already fetched and parsed, and the
cached path discarded an in-memory message to return
{"error": "Failed to mark email read"}. A transient IMAP failure therefore
turned a readable message into one that could not be opened at all.
Being authoritative should mean the reported flag state is truthful, not
that the body is withheld. The read now always returns the message and
carries mark_seen_failed so the client can roll its optimistic unread
marker back:
- _read_email_sync logs and reports a rejected STORE rather than raising,
and only writes the local index/list-cache transition when the provider
accepted it, so local state cannot drift ahead of the mailbox.
- A mailbox that refuses a read-write SELECT (shared archives, some
provider folders) falls back to a read-only selection and reports the
flag failure instead of failing the open.
- The route strips mark_seen_failed before caching, so a one-off failure is
never replayed to later readers.
- mark_seen now defaults to False on _read_email_sync. It was inert before
this branch and now mutates provider state; the one caller that wants it
off already passes it explicitly.
emailInbox and emailLibrary keep the message rendered when mark_seen_failed
is set and restore the unread state, rather than showing a failed reader.
