Under the hood

Useful1 Signal0

Storage Backend

Small marker files for deep links and cleanup timing can now be kept as storage keys.

What

The .deep-link-register-failed and .last-cleanup marker files now have storage-key equivalents.

Details

freshness is checked with stat instead of a filesystem stat, and the markers are written and removed with write/delete
a new error log fires when the cleanup stamp write fails

Strings lifted out of the shipped bundle, so the claim above can be checked against them.

Other releases about the same thing. Found by shared names or similar wording; neither means one caused the other.
