denkfabrik-li 8a6543073b Group membership is a library boundary, not just a list
The four routes that edit a group's membership -- add and remove, web
and API -- contain no authorization call of any kind. `can:edit_groups`
in front of them is the whole of it, and a permission is not a boundary.

The authorization sweep looked at these and let them stand, on the
grounds that groups are installation-wide by design: GroupsController
::index lists every group unfiltered, so list and single-object access
agree, and there is no listing/direct-access mismatch to fix. That is
true, and it is the answer to the question of who may *see* a group.
This is a different question: what a write to one *does*.

Joining a group hands the new member everything shared with it. When
that member is one of a client-scoped staff member's own clients,
File::scopeVisibleToClient hands the same content straight back to them
-- that scope is what StaffLibraryScope::files() is built out of. So the
one write turns a file they get a 403 on into a file in their library,
and the download that follows is a 200. ResolvesShareTargets draws that
line on the sharing path through canAssignGroup(); nobody drew it on the
membership path, and canAssignGroup() is *derived from membership*, so
whoever may edit the list also decides what the list entitles them to.

StaffLibraryScope::allowsGroupMembership answers it directly instead of
through the derived predicate, which is the wrong tool here twice over.
Membership asks about reach, so it checks reach: the client must be one
this staff member holds, and the group must not already reach past their
library -- no file assigned to it, and no folder shared with it, outside
StaffLibraryScope. A group nothing has been shared with passes trivially,
which matters, because canAssignGroup() would have said no to a group
that has no members yet and left a scoped staff member unable to put the
first client into one they had just created.

The same write has a second door. MembershipRequestsController::approve
joins a client to a group with identical consequences, under
`approve_groups_memberships_requests`, and deny() decides about somebody
else's client and emails them about it. Both go through the same
boundary, answering 404 to match the guard already above approve().

The queue and its sidebar badge are narrowed to the clients the viewer
holds, through one scope on the model that both read -- the rule the
comment badge in HandleInertiaRequests already states two branches down
("a client-scoped staff member is not shown a number they cannot act
on"), and the reason VisibleCommentScope owns its own pendingTotal()
rather than leaving the middleware to count for itself. Each row carries
the client's name and email, so an unnarrowed queue was also handing
those over for clients outside the roster. Unscoped staff still see every
pending request.

That narrowing is on the client, not on the group: whether a group is
reachable depends on what is shared with it, which is not a question to
ask row by row in a listing. A scoped viewer may therefore still be
shown a request they would be refused on -- one of their own clients
asking to join a group out of their reach. The names were the part that
leaked.

Unscoped staff are unaffected throughout -- both halves of the predicate
are true for them by construction. No seeded role reaches this: Client
Manager is the only client-scoped role that ships, and it holds no group
permissions, so a custom role is needed to get here at all.

The published API document gains a 403 on both member routes.
Regenerated with php artisan scramble:export; Scramble reads abort_unless
out of the method body but not out of a private helper, which is why the
guard is written out at each of the four call sites rather than shared.

ignacionelson 7646e99f33 Add an activity endpoint, so an integration can react rather than poll for shape
Every list in /api/v1 answers "what is there now". Nothing answered
"what happened", and for the two events people most want to act on there
was nowhere to look at all.

Sharing a file writes an assignment row and never touches the file, so no
amount of polling /files?updated_since= will ever show a share. A
download is recorded only in the activity log. So the most requested
automations for a file-sharing product — tell me when a client gets a
file, tell me when they open it — were not possible to build.

GET /api/v1/activity is one feed rather than one endpoint per event,
because the log already records every one of them and a caller filtering
by action gets whatever the application grows later without waiting for
us to expose it.

It reuses what already exists: view_actions_log is the permission the
activity screen uses, and ActivityLogScope narrows the rows the same way,
so a staff member limited to their assigned clients cannot read the whole
installation's log through a token when the screen would not show it.

Two deliberate limits. Class names never reach the wire — subject.type is
a stable public string, or moving a model between namespaces would be a
breaking change to a frozen contract. And no ip_address, though the
column exists and the screen shows it: a person looking at a log has
decided to look, where an integration streams every row to somebody
else's servers by default.

PollingQuery grew an optional column so it can walk a table that is
appended to rather than edited. The parameter stays updated_since
everywhere, because on an append-only log the two timestamps are the same
thing and one shape learned once is worth more than a second name.

ignacionelson 6e47d76ba6 ProjectSend 2.0.0
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.

This repository begins here. ProjectSend 2 was developed privately, and
that development history is not published — the previous generation
remains available, with its own history, at projectsend/legacy.
