Breaking changes

MongoDB migrations decoupled from API startup; must run `./faynoSync migrate up`/`down` explicitly.

Notable features

Full changelog

Decoupled MongoDB migrations from API startup: the server now starts with ./faynoSync only, and migrations run explicitly via ./faynoSync migrate up or ./faynoSync migrate down.

Added GET /tuf/v1/metadata/targets and GET /tuf/v1/metadata/delegated endpoints to retrieve TUF metadata for targets and delegated roles.
Added tuf typescript example.

Fixed telemetry period aggregation for range=week and range=month to deduplicate repeated client_id values across days instead of summing daily set sizes.
Updated telemetry integration coverage to validate that unique_clients, clients_using_latest_version, and clients_outdated remain deduplicated at period level.

v1.5.11 New feature 1mo

Notable features

Added `POST /tuf/v1/bootstrap/recovery` endpoint to rebuild Redis settings from persisted TUF metadata
Asynchronous `bootstrap_recovery` task flow with lock protection, prechecks, timeout support, and status reporting

Full changelog

Added POST /tuf/v1/bootstrap/recovery to rebuild bootstrap Redis settings from persisted TUF metadata for already initialized repositories.
Added asynchronous bootstrap_recovery task flow with lock protection, recovery prechecks, timeout support, and task status reporting.

Added RBAC edit permission checks for TUF task status, artifact publish, and artifact delete endpoints.
Added owner resolution middleware for team users so TUF artifact operations run under resolved owner context.

Unified bootstrap settings persistence and recovery via a shared Redis save path, including delegated role expirations and ROOT_SIGNING initialization.
