An entry of onProvideSearchResults may carry email: { id, accountId? }.
A click on it opens the message in the reader through the login that
reaches the account, as a list row does, and marks the entry while it
is open; any other click stays onAction.

The hook was called on every search, but nothing showed its entries,
the list waited for it, and an entry's onClick could not cross from the
plugin's sandbox. Its entries are now drawn as a block above the
search's message list, a group per plugin and source.
Each plugin is asked on its own (HookBus.collect) beside the search, so
the list no longer waits, and the answer to a search that was replaced
is dropped. The answer is checked: at most 20 entries, a key and a
title, plain text cut to its limits. A click goes to the plugin that
gave the entry as onAction with surface "search-results", the entry's
key and the query; ExternalSearchResult loses onClick.

Plugins that talk to Nextcloud, Paperless or an AI provider used to need
the password or key in their own settings, readable by the plugin and
stored in the browser. A plugin can now declare credentials in its
manifest and send requests "with credential X" through the server:
- `credentials` in the manifest: admin scope (secret and server from the
admin config) or user scope (the user connects an account; the server
address is fixed or chosen by the user)
- `/api/plugin-secrets`: the user's connected accounts, encrypted per
mail account under `PLUGIN_SECRETS_DIR`; listing never returns secrets
- `/api/plugin-proxy`: adds the secret and forwards only to the
credential's own origin, through the SSRF guard unless the admin set
the server up or listed it in `PLUGIN_PROXY_PRIVATE_ORIGINS`; no
redirects or WebDAV moves to other servers, streamed bodies capped at
512 MB up and 2 GB down, 300 requests a minute per plugin, 8 at once
per user, and one audit line per request without paths or bodies
- a capture mode that stores a secret from a sign-in response (Nextcloud
Login Flow v2) and removes it from what the plugin gets back
The hook buses, the permission each hook needs and the docs were three
separate lists that had drifted: 145 of 198 hooks were never fired and
nothing noticed. `lib/plugin-hook-catalog.ts` now names each hook with
its kind, permission, payload and when it fires; the permission check
reads it, and a test fails for any catalogued hook without a call site.
Groups still being wired in this branch are listed in that test.
Also:
- new before-hooks for archive, spam, read state, star, keywords, folder
changes, RSVP, event import, tasks, file moves, settings, identities,
filters and out-of-office, plus onComposerClose and onSyncStateChange
- removed hooks that can never fire: the S/MIME group (S/MIME is a
plugin now), onMobileViewSwitch, onSidebarAppChange and the
registerShortcut pseudo-hook
- smime:read no longer grants anything; manifests that name it still
install, with a warning
The admin page offered "User Plugin Uploads" and "Require Admin
Approval", but nothing in Settings used them: there was no upload, no
uninstall and no way to ask for approval, and the admin had no list of
requests. The approval code that existed pinned a hash of the code only
and showed the admin a manifest the browser sent, never the code.
Now:
- Settings > Plugins has an install button (when uploads are allowed),
a remove button for the user's own plugins, and lists in plain
language what each plugin may do, high-risk items first
- an install sends the ZIP to the server, which reads the manifest and
code itself and pins the request to a hash of both
- the admin Plugins tab lists requests with the code and approves or
denies them; a user may have 10 open requests
- a user plugin is checked again on every start, so a revoked approval
or turning user plugins off takes effect
- the consent dialog and the plugin settings are translated, use the
theme colours, and show the sites a plugin may send data to
Plugins rendering in calendar-event-actions could never see the event's
uid or participants, so a meeting plugin minted a fresh room on every
click and could never propagate attendee or time changes; and of the
declared calendar hooks, none ever fired — the form-save bus existed but
had no emit site anywhere.
- calendar-event-actions eventData gains uid (undefined for new drafts)
and attendees (email list), so plugins can key meetings off the event
and fan out to participants.
- onCalendarEventFormSave now fires in handleSave as a transform:
handlers receive the accumulated patch plus the form view and may
return a patch (currently { virtualLocation }) merged into the saved
event — a meeting plugin refreshes its link in the same save that
sends scheduling messages, so attendees always get the current URL.
- Both buses are typed; contract tests cover the patch flow.
Testing: vitest plugin-hooks suite (41 passing), tsc clean, eslint clean
on touched files.
The theme sanitizer was a short denylist. It missed protocol-relative
`url(//host)`, schemes and keywords spelled with CSS escapes
(`url(\68ttps:...)`, `@\69mport`), `image-set("https://...")` and
`@font-face` sources, so a theme could load remote resources from the
app document. `validateThemeSelectors` was never called, so theme CSS
could also target `input[type=password]` or restyle real UI. The admin
routes and the zip validator only sanitized when the safety check
failed, and CSS returned by the `onThemeBeforeApply` plugin hook was
injected as-is.
- every `url()` except a `#fragment` and every `image-set()` is removed
with its arguments; a banned construct spelled with escapes drops the
whole stylesheet
- theme CSS keeps only `:root` and `.dark` rules (no nested rules),
plus `@font-face`, `@keyframes` and `@media`/`@supports` wrappers
- sanitizing is unconditional everywhere, including plugin-transformed
CSS; compiled token values may not contain escapes or `url()`
Every existing plugin slot renders wherever it's placed in the page (a
toolbar row, an attachment's hover-action bar, etc.) and is constrained
by that spot's own CSS - fine for small controls, but there's no way
for a plugin to show a large custom UI (a graphical file browser, a
multi-step wizard) since even a position:fixed overlay rendered from
inside such a slot is clipped to the surrounding row's own layout, not
the real page (confirmed live building the webdav-storage plugin: a
folder browser rendered but was squeezed into an unusable sliver).
Adds:
- host-dialog.ts: new 'custom' DialogKind + awaitCustomDialog(), reusing
the existing confirm/alert/prompt queue plumbing.
- host-api.ts: 'ui.openDialog' API method.
- runtime.tsx: sandbox-side api.ui.openDialog(opts) proxy.
- plugin-types.ts: new 'plugin-dialog' SlotName - a plugin implements
this slot with its actual custom UI.
- plugin-dialog-host.tsx: renders the requested slot via the existing
PluginIframeSlot INSIDE the dialog's real app-root fixed overlay
(position: fixed; inset: 0, above everything) instead of the
confirm/prompt form, for kind: 'custom'. Resolves via a generic
onResult callback in extraProps (marshalled the same way
composer-attachment-source's onAttach already is - no new plumbing
needed there).
A plugin calls api.ui.openDialog({ slot: 'plugin-dialog', extraProps,
title, width }) and awaits the Promise, which resolves to whatever its
own slot component passes to props.onResult(), or null if the user
closes the dialog without doing so.
Two new extension points for third-party attachment/cloud-storage plugins
(e.g. a WebDAV/Nextcloud file browser), neither of which the plugin API
currently supports:
- attachment-actions: a new slot rendered into every attachment's hover
action row (all six render paths: beside-sender/below-header/mobile,
each in its compact and expanded-popup form), with the AttachmentInfo
(name, type, size, blobId, emailId) passed through extraProps. Lets a
plugin offer a 'save this attachment elsewhere' action next to the
existing download/preview buttons - previously the only per-attachment
hook was the read-only onAttachmentDownload observer.
- composer-attachment-source: a new slot rendered in the composer toolbar
next to the existing composer-toolbar slot, with an onAttach(upload)
callback in extraProps. Lets a plugin that has already uploaded a file to
the JMAP server itself (api.jmap.uploadBlob) - e.g. a file picked from an
external cloud storage browser - have it added to the current draft as a
real attachment. Previously there was no way for a plugin to add an
attachment to the draft at all; the closest existing mechanism
(onBeforeBlobUpload's ExternalAttachmentResult) only replaces a locally
picked file with body text/a link, it cannot add a brand-new attachment
from an external source.
Both slots follow the existing PluginSlot pattern (calendar-event-actions):
render nothing when no plugin offers the slot, so this is purely additive.
Motivating use case: the existing nextcloud-attachments community plugin
uploads local files to Nextcloud and appends a share link to the message
body - useful for large files, but there was no way for a plugin to do the
inverse (attach a file that already lives in cloud storage as a real binary
attachment, not a link) or to let attachment recipients save an incoming
attachment back out to their own cloud storage. These two slots make both
directions possible without touching plugin-store or the sandbox bridge -
existing slot/extraProps plumbing (see calendar-event-actions) already
supports arbitrary POJO props.
Typing a contact group's name in a recipient field suggested the
individual members, and "send email to group" on the contacts page
filled the field with one chip per member - the group itself never
appeared anywhere.
The autocomplete now offers the group as a single entry (group icon
plus member count), and selecting it - like the contacts-page action -
inserts one chip named after the group that carries a snapshot of its
members. The chip expands into the deduplicated member addresses when
the message is sent or saved as a draft, mirroring how Outlook handles
distribution lists. Expansion happens where the outgoing address lists
are built, so validation and every plugin hook see real addresses.
Group chips survive the composer's string boundaries (draft data, dirty
compare, the contacts-page hand-off) as RFC 5322 group syntax
("Team: a@x, b@y;"). A bare colon reliably opens a group there because
display names containing a colon are always quoted. Typed text only
parses as a group when it carries at least one valid member, so stray
"Subject: hello" input stays a plain recipient.
RecipientSuggestion gains an optional group field; plugins that ignore
it keep working unchanged.
