denkfabrik-li 9ddd39c41d Refuse to provision over a deleted account's address instead of crashing
The unique index on `email` spans soft-deleted rows -- AvailableEmailRule
is built on exactly that, so a deleted account keeps its address until
erasure removes the row. The registration form learns this from
validation. The machine paths have no form: a directory or an identity
provider hands over an address and provision() inserts it.

Measured on main, a client deleted last week signing in through a
provider that may auto-provision:

  GET /auth/google/callback → 500   (QueryException, unique constraint)

Same shape through LDAP at POST /login. Nothing is created, nothing is
signed in, and what the person meets is a server error.

Both provisioners now ask ClientProvisioning::addressIsFree() first and
refuse. The social flow already has a refusal for an identity it cannot
provision -- "There is no account here for that address." -- which is also
all a stranger should learn: whether an address was once an account here
is not the provider's to publish. The LDAP flow falls through to the
ordinary failed sign-in.

Deliberately not resurrecting the deleted account. Restoring one because
a directory says the address exists is a decision for a person, not a
side effect of somebody logging in.

Two tests, one per path: the sign-in is refused, nothing is created, and
the trashed row is still trashed. Both go red without the fix.

ignacionelson 463e86f82b Refuse an account past the seat count an operator sold
Opening user management on cloud (623ad68) left a managed tenant able to
create staff accounts without limit. This is the other half, and the two
belong in the same release.

max_clients and max_staff_users are numbers the platform sells and does
not enforce — grep finds them only being passed to screens. The
application is the only process that can count against them, so it
accepts the number from the environment and refuses to exceed it. That is
not the same as inventing a plan tier, which is what config/api.php
declines to do when it will not key a rate limit off billing: nothing
here knows what a plan is.

## One definition

staffUsed() and clientUsed() are public and are what the guards read. A
control plane showing "2 of 3 used" from its own query, beside an
application refusing the fourth from a different one, disagrees
eventually — over an inactive account, or a deleted one — and the
disagreement reads as a billing fault rather than a counting one.

## What counts, and the consequences somebody has to explain

An inactive staff account occupies its seat. Excluding it would make
deactivation a way around the cap rather than a way to revoke access,
since reactivating is one click. The cost is an awkward incentive —
deactivating is the safe removal and keeps paying, deleting frees the
seat and asks what happens to the files — and it is better explained than
hidden.

A client awaiting approval does not. Self-registration is open to
strangers, and counting a pending request would let anybody exhaust a
paid limit from the outside, turning a pricing tier into an availability
control. The seat is spent at approval, which is where the guard sits.

A soft-deleted account frees its seat, though not its address —
AvailableEmailRule holds that until erasure. So a seat can be free while
re-adding the same person is still refused, which is the address rule
rather than this one.

## Eight doors, eight tests

There is no single User::create() to guard. StaffAccounts::create()
covers both staff controllers, but a promotion takes a staff seat without
creating anything, a demotion takes a client seat, ClientProvisioning
serves registration and LDAP and social sign-in alike, and approval turns
an uncounted request into a counted client.

A cap is only a cap if every door asks, so there is a test per door and
each was verified to fail without its guard — eight red, with the two
"must not change" cases green either way. DownloadAllowance's shape for
DownloadAllowance's reason: the failure mode is one of them quietly not
asking, invisible from everywhere except the door that forgot.

projectsend:admin is deliberately uncapped and has a test saying so. It
is the recovery path, and anyone who can run it can also edit the
environment the cap comes from.

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.
