Least Authority June Update

[Lauri Hmel]

Hello All!

The following covers Least Authority’s work for the Tahoe-LAFS Software
Foundation during June 2025:


   -

   Create Tahoe-LAFS Mobile from PrivateStorage Mobile:
   -

      Refactoring of core libraries and magic folder is now complete (but
      for minor details) and may be inspected at
      https://gitlab.com/tahoe-lafs/bala-lafs . The advantages include:
      -

         Orderly dependency graph resulting in more comprehensive
         generalisations.
         -

         A reduction of line count to roughly 40% of the original.
         -

         Only uses basic Haskell techniques, not even requiring type
         classes.
         -

         Better modelling of capabilities leading to better code
         factorisation and type safety.
         -

         A single tree-like cache with driving functions that houses
         isolated files, plain folders, magic folders and
pending-download status.
         It also preserves downloaded data and notes the error-cause
when a change
         of grid config makes it unavailable, and it will support e.g. conflict
         resolution when the time comes.
         -

         Magic folder read support (currently still just takes the newest
         participant version) based on said tree-like cache.
         -

         Closer attention to laziness to handle files larger than main
         memory.
         -

         A robust, fair and efficient concurrent share fetching algorithm.
         -

         A base from which to easily implement a storage/cloud server.
         -

         Consistent error handling.
         -

      The next task is to port the mobile app to the new core/MF library.
      This will simplify the mobile app code.
      -

   Recovery Phrases:
   -

      Looking at remaining ZKAPAuthorizer integration issues and making
      ZKAPs optional (Gridsync #733)
      -

   Replacement for the Current Issue Tracking System and Web landing page (
   trac#4095 <https://tahoe-lafs.org/trac/tahoe-lafs/ticket/4095>)
   -

      Deploying Forgejo and its requirements (mailer and backups -
      infrastructure#44
      <https://github.com/tahoe-lafs/infrastructure/issues/44>)
      -

   Continued work on infrastructure:
   -

      To manage shared secrets with a ”infrastructure-pass” repository (
      trac#4177 <https://tahoe-lafs.org/trac/tahoe-lafs/ticket/4177>)
      -

   Maintenance and Community Work:
   -

      Supporting and pair programming with other members of the community
      on writing tahoe client tests.


Additionally, a few hours of our time was spent on project administration
and coordination.
