0.3.10 - 2026-08-28

Release Notes

Added

• Mark::Recorded, and an origin note that survives what the App Sandbox
  destroys. Under the sandbox the platform marks whatever the calling process
  writes and refuses to have that mark replaced, so carry reported
  AlreadyMarked and the source's value was lost. The gate was never the
  problem — the copy is gated whoever marked it — but the answer to where did
  it come from was, and a caller that reports provenance could no longer tell a
  container that arrived from elsewhere from one made on the machine. Found in
  slipcase-desktop, where saving an edit to a downloaded container made the
  card's arrived from elsewhere line disappear.

  carry now keeps the source's quarantine value verbatim under
  com.excelano.slipcase.origin when the platform refuses to carry it, and
  answers Mark::Recorded rather than Mark::AlreadyMarked when it did.
  arrived_from_elsewhere consults the note. carries_a_mark deliberately does
  not: the note gates nothing, nothing outside this crate reads it, and a
  caller deciding whether to hand a payload to the system must not read our own
  writing as the platform's word.

  Three things measured inside a bundle signed with the sandbox entitlement
  rather than assumed: the refusal is specific to com.apple.quarantine and an
  attribute of our own goes on without complaint; the note survives
  -[NSFileManager replaceItemAtURL:], which is the operation that destroys the
  attribution; and no supported API preserves the original attribution, since
  NSURL's quarantinePropertiesKey succeeds and then substitutes the calling
  process as the agent.

  macOS only. Windows can reach the same branch and does nothing there yet, for
  want of a measurement; Linux cannot reach it, because its carry never fails.
  Nothing changes for a caller that is not sandboxed.

  Mark is #[non_exhaustive], so the new variant is not a breaking change for
  anyone matching on it.
