- The message for send checks is built after waiting for required
checks that are still starting: a send right after sign-in gave them
no external recipients and no file types.
- A plugin's forward is held too while a required check is down, also
with no plugin listening.
- A plugin the admin forces on that hasn't reached this browser yet (a
new device, a failed plugin sync) counts as starting.
- A check that stopped working says to reload or tell the admin.
- The files that were checked are the ones sent, and recipients a
plugin adds after the check are checked again.
- A file Bulwark couldn't read is marked unreadable; a text file
starting with "MZ" is text, Java and Android apps are told from ZIPs.
Changed assertions: runPluginSendCheck takes a builder and reports
guard-loading or guard-failed instead of guard-down; the composer test
of an auto-disabled guard expects the stopped_working text; the sniff
tests give programs a zero byte, as real ones have, and expect
unreadable on a file that can't be read.
Admins write an HTML and a plain-text signature with placeholders on
Organisation > Signatures, per scope. Users fill in the details it asks
for once, under Settings > Account. Without a lock it is the default for
addresses without a signature of their own; locked or hidden, it
replaces every signature.
- `lib/org-signature.ts` fills the templates: values escaped, lines whose
placeholders are all empty dropped
- the composer applies it right before the plugin signature, so new mail,
replies, forwards, re-opened drafts, plain text and identity swaps all
take it the way they take an identity signature; quick reply too
- a send finaliser puts a locked signature back once when it was deleted
- the identity editor shows the filled-in signature read-only with "Set
by your organisation" when locked, and no editor when hidden
- `signatureDetails` is a synced setting
