SSO — single sign-on for all of NoCloud (Authelia).
PWA — the installable web app, with offline caching.
Snapshot — a full copy of the database taken before a write; lets you roll back.
dbsafe — the layer every database write passes through: a prior snapshot + change ledger.
Journal — the single append-only log of every archive operation: what changed, from what to
what, and why. See Curating your archive.
Run / op_run — one batch of journaled operations (an import, a bulk date fix). The unit
you revert: one command walks the whole batch backwards.
Sidecar (XMP) — a small metadata file written next to a photo (dates, tags, GPS) so the
original bytes are never edited.
Quarantine — where a deduplicated loser or an uninstalled app's tables go: renamed and set
aside, recoverable — not erased.
Review queue — where uncertain proposals wait for you to accept, override or reject them;
nothing is applied until you resolve it. See Curating your archive.
Doctor — nocloud doctor, the 16-check diagnosis of an installation. See
Platform.
Daemon — the small runtime API on the workstation that serves platform state and runs jobs
on demand. See Platform.

schedule, with host, timeout and output.
Module / App Store — a section installed or removed from the App Store, with its
own permission manifest.
Connector — a module with disclosed, boxed-in database-write access: it parses a file you drop
and hands the rows to a shared ingest engine, never writing SQL itself. See
The Store.
Ingest engine — the core's single, generic write boundary connectors use: validates every table
and column name, binds every value as a parameter, and only allows a connector to write the tables
its own manifest names.
Matrix — the open messaging standard; its event model is what the message archive uses.
ISO 20022 — a banking standard; its purpose codes (SALA, GDDS…) categorize movements.
MCC (ISO 18245) — a card merchant category code.

sensitive content.

Override — a manual rule that takes priority over automatic classification.
calc_ — the prefix for derived/precomputed fields.
Danger zone — the credential inventory in Settings → Account & security.
