A client who may create folders creates them at the top of the library,
beside the ones staff made, and their uploads land at the root too. An
administrator opening /files gets one flat pile with nothing saying which
parts belong to whom.
With the new "Give each client a folder of their own" setting, every new
client gets a folder named after them and it acts as their root: what they
upload and any folder they create goes inside it. /files becomes a list of
clients rather than a pile.
The sentence this feature has to keep true: **the home is a default
location, not a boundary.** Folder::scopeVisibleToClient is untouched, so a
folder staff shared with a client still reaches them and sits beside their
own. Making the home a jail would have silently revoked every share that
already exists -- a data-access change wearing the clothes of a tidying-up
feature. There is a test named after that rule.
What the client sees is the *inside* of their folder, not a folder wearing
their own name, which is not information to them. The breadcrumb is trimmed
of it for the same reason: "Invoices", not "Acme Ltd / Invoices".
Some decisions worth naming:
- **A column, not a convention.** `folders.home_for_user_id`, unique.
Matching on the name breaks the moment two clients share one, and
`created_by` plus a null parent catches every root folder a client ever
made themselves. The question is asked on each upload and each portal
listing and the answer has to be exact.
- **created_by is the client**, because that is how scopeVisibleToClient
already grants somebody their own folder -- no assignment row to keep in
step with it. That is also why this writes the row rather than calling
FolderService::create(), which takes created_by from auth()->id().
- **On model events**, not in the services that make and rename clients.
There are nine of those (ClientAccounts, ClientProvisioning, the profile
screen, two update endpoints, AccountConversion, invitations, LDAP,
social) and a rule repeated in nine places is missing from the tenth.
- **Turning the setting on creates nothing.** Existing clients get a folder
when an administrator presses a button that says how many are waiting,
and it reports created/total/already-had afterwards. Somebody should be
able to switch this on, look, and switch it off without having
reorganised a library. It moves no files either.
- **Nobody deletes a home from a folder screen**, staff included, and the
client cannot rename theirs -- they own it, so ownership alone would have
let them, and its name follows the account anyway.
- **The name always follows the client**, over a hand-typed one. A folder
still called "Acme Ltd" under an account now called something else
misleads the administrator the feature exists for.
Verified in a real browser as well as in tests: the screen mounts, the
panel reads "24 of your existing clients have no folder yet", and pressing
the button answers "24 of 24 clients got a folder. 0 already had one."
Staff can now invite a specific address to register instead of typing a
password for somebody and finding a way to get it to them. The invited
person sets their own, the link is locked to the address it was sent to,
and an invitation always activates the account regardless of the
auto-approve setting -- naming an address is already the decision the
approval queue exists to make for one nobody named.
Two fixes ride along: outgoing mail now reads the installation's own site
name in its title, header and signature rather than the one baked into
config('app.name') at install time, and the CSRF cookie name is read per
request rather than captured once at load.
Follow-up work, tracked separately: an invitation cannot be cancelled --
there is no pending-invitations screen and no revoke, so letting one expire
is the only way to take it back, which the self-service resend button then
undoes. Redemption also needs the address-availability check every other
non-form caller of ClientProvisioning makes.

v1 could preview four kinds of file in a modal — images, video, audio and
PDF. v2 previewed only images, and not by decision: preview shipped as part
of the image *thumbnail* work (1c68aa1), so "previewable" quietly became a
synonym for "GD can decode it". FileThumbnailController::preview() gated on
ThumbnailGenerator::SUPPORTED_MIME_TYPES, the frontend mirrored the same
four types, and the dialog was a hardcoded <img>.
Rather than widen that list — it drives pathFor(), extensionFor(),
generate() and FileDiskCleanup, and a video reaching getimagesize() is a
500 — this separates the two questions. PreviewKind now answers "may these
bytes be served inline, and what element renders them?", while
ThumbnailGenerator keeps answering the narrower "can this app decode it
itself?", which is what renditions, the cache and the watermark hook
actually depend on. Image delegates to it so the two cannot drift.
The allowlist stays a security boundary: mime_type is sniffed from the
bytes, so text/html and image/svg+xml remain excluded, and PreviewKind is
deliberately narrower than "formats a browser might cope with" — no
quicktime, avi or matroska, because an embedded player for those shows a
black rectangle. Those still download exactly as before.
docs/security-audit-2026-08-05.md finding 1 recorded that adding
application/pdf "should be a conscious decision". This is that decision,
and three things were measured rather than assumed:
- An <iframe sandbox> cannot be used. Chrome refuses to run its PDF viewer
in a sandboxed frame at all (ERR_BLOCKED_BY_CLIENT, with or without
allow-same-origin) — the attribute removes the feature, it does not
harden it.
- nginx's `Content-Security-Policy: sandbox; default-src 'none'` on
/protected-files/ does work (a <video> frame lands in an opaque origin),
but Chrome exempts its PDF viewer from it, so it is not what protects
the PDF case.
- What does is the allowlist plus the browser's own PDF sandbox, where PDF
JavaScript has no DOM and no cookies.
Range requests were verified end to end: 206 with a correct Content-Range,
a byte-perfect file reassembled from three ranges, and a real browser
seeking to 10s of a 20s clip. nginx drops the upstream Content-Length on
the X-Accel path, so there is no collision.
Two settings, both defaulting on so no installation loses what it has:
clients_can_preview_files and public_listing_preview_enabled. Staff are
never gated. The anonymous side needed a route of its own — there was no
public preview endpoint — with its own throttle bucket, since a bare
throttle: shares one counter across that whole block.
A preview now logs at most one FilePreviewed per viewer per file per five
minutes: a <video> turns one deliberate act into a long tail of Range
requests, and a row each would bury the log.
Also fixes a layout bug the tests could never catch. A portal file row was
flex justify-between with three children — name, comment trigger, download
— so the middle one settled wherever the name happened to end and the
comment icon sat at a different place on every row. The name block now
takes the slack and every action lives in one trailing group, with the
comment trigger in a fixed-width slot so the icons form a column. And
because half the previewable files have no thumbnail to click — a PDF, an
mp3 and an mp4 all render as a generic icon — every row gains an explicit
PreviewAction beside DownloadAction, matching whatever style that theme
gives its download control.
Client file sharing, rebuilt from the ground up: a private area per
client, resumable uploads, folders, groups and categories, sharing with
expiry dates and download limits, comments, file versions, an activity
log, a REST API, and sixteen languages.
