0.1.1

Patch — the built-in ETS store keeps its own contract when it isn't running.

Fixed

  • Reading from Keyfob.Store.ETS raised instead of answering :error. The behaviour declares get(key()) :: {:ok, value()} | :error, but the implementation called :ets.lookup/2 straight out, which raises on a table that does not exist — so the contract broke whenever the store was not running: during startup before the child begins, between a crash and the supervisor's restart, or in a host that never added it to a supervision tree. A caller cannot reasonably be asked to rescue a documented lookup.

  • take/1, update/2 and delete/1 exited instead of reporting. They call a named GenServer, and a call to a process that is not alive exits. For operations that already have a failure value in the behaviour, that exit is strictly worse than the failure they declare: take/1 backs consume/2, so an unreachable store crashed the caller rather than simply not signing anybody in — a 500 on a web login where "this link is invalid or has expired" was both the honest answer and the same outcome.

    They now return :error (:ok for delete/1, where an entry in a store that is gone is gone, and which runs as cleanup after a successful take/1 where exiting would fail a flow that had already succeeded).

    put/3 is deliberately unchanged and still fails loudly. It has no failure value in the behaviour, and inventing :ok for a write that did not happen would hand back a token nothing has stored — a request that cannot be approved, failing later and further from the cause.

0.1.0

Initial release.

Added

  • QR device-handoff login rendezvous: create_request/1, peek/2, approve/3, deny/2, consume/2, and the topic/subscribe helpers.
  • Secret split — the QR-borne request token can never log anyone in; a separate one-time login token is minted at approval and delivered only to the waiting LiveView over PubSub.
  • Keyfob.Store behaviour with a built-in single-node Keyfob.Store.ETS (serialized update/2 + take/1 for lost-update and single-use safety, background expiry sweep).
  • Keyfob.QR inline-SVG renderer (via eqrcode) and headless Keyfob.Components.panel/1 + confirm_screen/1.
  • Keyfob.Live glue for the desktop panel.
  • Telemetry for every transition.
