api.email.getThread fetches only the newest 50 messages of a thread
(Thread/get, then Email/get for those ids) instead of all of them with
their bodies. api.email.getThreadCount answers the number of messages
from Thread/get, with its own rate limit.
plugin-host-thread.test.ts now expects getThreadEmails to be called with
{ newest: 50 }, the new option that limits what is fetched.
api.host.features.sidePanel now says whether this plugin may offer the
app-side-panel (ui:side-panel granted), not only that the webmail has
it. A plugin enabled before an update added the permission can then say
so instead of offering a switch that does nothing. The host computes the
assistant's flags per plugin for a frame's init and for each push.
plugin-host-features.test.ts: the host bridge assertions take the
assistant's flags as the test plugin sees them (it lacks ui:side-panel,
so sidePanel is false there).
The AI assistant's "more actions" need host calls today's plugin API
lacks. Area c of lib/plugin-sandbox/assistant adds them:
- `calendar.respond(emailId, status)`, new permission calendar:respond:
answers an invitation of the user's own account through
lib/calendar-rsvp.ts, like the reader's banner
- `calendar.deleteEvent` now returns an undo token for a single event;
`calendar.undoDelete` creates it again from the host's copy
- `filters.list/create/undo` over Settings > Filters' model; forward,
redirect, reject, discard and keep are refused, and so are folders
that are shared or not the account's own
- `email.batch/undoBatch`: up to 200 messages through the store's
batch functions, restore points first, one entry in the undo history
- `vacation.get` also says whether the out-of-office forwards mail
- `app.describeSettings`, `app.setSettings` and `app.undoSettings`, new
permission settings:change, over the allow-list in
lib/settings-schema.ts, refusing locked, hidden, restricted and gated
settings when the change is made
Undo tokens stay in the host for 30 minutes, bound to the plugin and
the account. app.getSettings now shows every setting setSettings may
change. settings:write's text is reworded to what it gates (tags).
plugin-host-api-app-info gains a test; its other assertions are as
they were.
EmailReadView.attachments gain cid and alt for images the HTML shows
inline. plugin-projection.test.ts now expects the cid on its inline
logo, since the view carries it.
api.email.getAttachmentText reads PDF (pdf.js), Word, Excel, PowerPoint
and OpenDocument files (own reader over fflate and DOMParser, unpacking
capped at 50 MB), text, CSV, HTML, calendar and address files, and
answers with a status for what it can't read. The extraction lives in
lib/attachment-text so Files can use it too.
The sandbox runtime now copies every flag the host sends into
api.host.features; before, it kept only the three core flags, so the
assistant's flags never reached a plugin. The host bridge assertions in
plugin-host-features.test.ts compare against the core flags plus the
assistant's (withAssistant), since the init payload and host-change now
carry attachmentText too.
The assistant's new host calls come in four areas (context, actions,
Files, the panel in every view), built side by side. Each area gets its
own files under lib/plugin-sandbox/assistant for its permissions, method
table, dispatcher, host feature flags and sandbox methods; the shared
files only read the merged result. No area adds anything yet. The host
features test now compares against the core flags plus the areas' flags.
