The download counter was read-modify-written, so two concurrent retrievals
recorded one. It is an audit trail — under-reporting is the failure mode it
must not have.
The creation-race test broke when issuing moved into a transaction: its
simulated competitor writes inside our transaction, so the rollback removes
that row too. It now asserts what actually matters (the loser is told, and
creates nothing) and states what a single-connection sqlite test cannot show.
This test was red in the previous commit — my mistake for committing before
reading the run.

Once revealed, the plaintext sits in the handoff cache for ten minutes, and the
modal read it from the token alone. A former owner could keep pulling the key
out of an open modal after revocation — the exact window purgeSecret() exists to
close. Every request now re-checks the policy and drops the handoff when it no
longer holds.

Reworked after a design consultation with Codex, which pushed back on my first
proposal in three useful ways.
Ownership and rights:
- vpn.manage split into vpn.view.all and vpn.manage.all. Seeing an access is
not managing it, and neither is holding its private key.
- Record-level rules live in VpnPeerPolicy, not in permissions: an access
belongs to a person, and ownership is what grants sight of it. Every operator
reaches the page, but sees only their own unless they may see all.
- Issuing an access is not self-service — it reaches the management network, so
it needs vpn.manage.all even for oneself.
- New Developer role: sees everything, manages nothing. Writing code does not
imply authority over other people's access.
- kind (staff|host|system) replaces a null user_id that had to mean two
different things at once.
Config storage, opt-in per access:
- Downloading is owner-only — explicitly NOT for view.all or manage.all. An
admin who needs access revokes this one and issues their own, which keeps the
record of who holds what honest.
- The password is asked on EVERY retrieval, rate-limited. Laravel's
password.confirm keeps a 15-minute session stamp, which would authorise
unlimited later downloads from an unattended browser.
- Stored under VPN_CONFIG_KEY, not APP_KEY: a leaked application key must not
also hand over the management network. Purged on revocation and when a staff
member is revoked — console taken away, tunnel left open was the worst case.
- The plaintext never enters a Livewire snapshot (the page polls every five
seconds); the component carries an opaque handle instead.
Also: copy button works without HTTPS again (navigator.clipboard only exists in
a secure context, so over http it silently did nothing), plus config download
as a file and a QR code for the mobile apps.
