Running the server meant running the API by hand: invites, accounts,
groups and grants existed only as endpoints and CLI commands, so the
browser could create a vault and nothing else.
/web/groups walks the group tree and opens onto one group's members,
roles and vault access, including the grants it inherits from above and
where they come from. /web/users lists the accounts you may see, and
lets a server administrator disable, enable, clear a lost second
factor, promote, demote or delete one. /web/invites shows the
outstanding links with their use counts, issues new ones and revokes
them.
Every administrative change is now a function of the state and the
caller in admin.go, which both the JSON handlers and the forms call. The
alternative was a second copy of the permission rules behind the pages,
which would have drifted on the first change. The same move gave the API
the two verbs it was missing: DELETE /api/v1/invites/{token} and
PATCH /api/v1/users/{id}.
Account changes are server-administrator only. A group administrator
decides who reaches which vault; disabling an account or clearing
somebody's second factor reaches past the group they share. Disable and
delete revoke that account's sessions, and the three changes that would
lock the caller out are refused on their own account.
Pages go through webPage and forms through webForm, so the session and
CSRF checks cannot be forgotten on a new form. No page carries any
JavaScript.

Why: the point of a sync server is that two people can work at once. Picking
a winner was all this one could do while it could not read a vault.
What, end to end:
- A vault is created at /web or with `keeporg vault -create`: the server
builds an empty KDBX 4 file, encrypts it with the password from the form,
and stores it as version 1. An existing database can adopt a stored key
with `keeporg db -id <id> -store-password`, which is verified against the
stored file before it is accepted.
- A stale push to a `merge` vault is no longer refused. The server opens the
stored version and the pushed one in memory, folds them together, and
stores the re-encrypted result. Clients push as usual and pull what comes
back. Any failure answers 409 merge_failed and the client keeps its copy
aside, so a failed merge still loses nothing.
- At rest: vault contents stay KDBX-encrypted as always. A merge vault's
password is kept AES-256-GCM-wrapped under a master key that lives outside
the data directory, bound to the vault id, never returned by the API. A
stolen data directory is ciphertext; a stolen data directory plus the
master key is not. The server runs without a master key and simply refuses
to create or merge vaults.
This moves the server inside the trust boundary for vaults it can merge,
which is inherent to merging and is stated plainly in the README, the
handover notes and the web form itself. Key-less strategies are unchanged and
remain the default for a database created without a password.
Proved: two clients editing the same version are merged rather than refused,
the newer edit of one entry wins, a merge failure leaves the stored vault
untouched, `merge` is refused without a stored key, the wrapped key never
appears in state.json or the API, and the web interface rejects a form
without its CSRF token, withholds its cookie over plain http, and only offers
groups the user administers. Checked by hand against the real thing: a vault
created in a browser, edited by keepassxc-cli on two sides from the same
version, merged by the server, and both entries read back out with
keepassxc-cli. make check, make test-race, android lint and both .deb builds
are clean.
Why: collaborative KeePass use needs one arbiter of "who wrote last" that
never sees a master password, plus access control that follows an org chart.
What: stdlib-only Go server. Metadata is a single JSON document with one
writer and atomic commit; KDBX payloads are versioned blobs on disk. Access
comes from a group tree where a grant on a group reaches every member below
it. Login is password+TOTP, invite links, or OIDC through a browser-approved
device flow. Pushes carry If-Match and are arbitrated by a per-database merge
strategy (server-wins by default). Updates are pushed to clients over SSE.
Proved: go test ./internal/... covers RFC 6238 vectors, ACL inheritance and
isolation, store rollback, blob pruning, every push verdict, and an
end-to-end HTTP pass over login, conflict, force, read-only grants, invite
redemption, TOTP enrolment, device login and the event stream.
