Addresses the gaps identified in the last audit.
Restore (was a stub returning "not yet implemented"). Every repository shares
one connection pool, so the database cannot be swapped underneath a live
server. Restore is therefore two-phase: RestoreBackup validates the file and
stages it beside the database; db.New applies it before the pool is opened,
which is the only safe moment. The database being replaced is preserved as
<db>.replaced-<timestamp>, and stale -wal/-shm are removed so SQLite cannot
replay the old journal over the restored file. Validation is strict — SQLite
integrity_check plus a schema probe — because applying an unrelated file
would destroy the install. GET/DELETE /api/v1/backups/restore inspect and
cancel a staged restore. The CLI does both phases at once, since it runs
standalone; `orchestrad backup` was also a stub and now works.
Secret key. With nothing configured the key is generated once and persisted
to <data>/secret.key, so restarts reuse it and moving the stack to another
server is a matter of copying the data directory. Upgrades are handled: if a
database already exists the install was silently running on the legacy
built-in default, so that value is adopted and written out rather than
replaced — generating a fresh key there would make every stored credential
undecryptable. The file is owner-only (ACL-restricted on Windows).
Multi-arch image: buildx now emits linux/amd64 + linux/arm64, matching the
architectures the release binaries already covered. The Dockerfile
cross-compiles via TARGETARCH rather than emulating, so arm64 costs little.
CSRF: the middleware previously checked only that a header was *present* and
was never wired up, and /auth/csrf returned "csrf-token-placeholder". Tokens
are now nonce + HMAC-SHA256 signed with the application secret, validated
properly, and the middleware is mounted on /api/v1. Bearer and API-key
requests are not CSRF-reachable and pass through untouched, so this is
transparent to the SPA and to API clients.
Also: the Windows store import drops CRYPT_EXPORTABLE (the store copy is not
the source of truth — <data>/tls holds the key, so portability is unaffected
and a non-exportable server key is the better posture), the PFX password is
written to server.pfx.password beside the bundle so an operator importing it
by hand does not have to hunt for a password they never chose, and the
"renewed" log line now reflects whether a leaf was actually issued instead of
guessing from its age.
Verified live: backup -> stage -> restart applies and preserves the previous
database; secret key generated, adopted, and read back across restarts with
the credential check confirming decryptability; CSRF endpoint issues real
signed tokens.
