I can see that (at least one of) my theories for Isabelle2025-1 at
https://isa-afp.org do not contain recent updates. More specifically,
they differ from https://foss.heptapod.net/isa-afp/afp-2025-1.

Am I wrong assuming that this should not be the case?

Five new entries have become available from the home page that were previously only available in the development version:

The should indeed be equal to afp-2025-1.

It would be helpful to point out which URL. It might be a caching issue, or something has gone wrong for that entry.

Cheers,

It was caching, indeed. I was also confused by the fact that the
development version https://devel.isa-afp.org/ seems to be not actual
for real.
Thank you and sorry for a false alarm.

  • Complex Lattices, Elliptic Functions, and the Modular Group

  • Typed Ordered Resolution
    by Adnan Mohammed Ahmed and Balazs Toth
    https://www.isa-afp.org/entries/Typed_Ordered_Resolution.html
    Ordered Resolution is a proof calculus for reasoning about first-order
    logic that is implemented in many automatic theorem provers. It works
    by saturating the given set of clauses and is refutationally complete,
    meaning that if the set is inconsistent, the saturation will contain a
    contradiction. In this formalization, we restructured the completeness
    proof to cleanly separate the ground (i.e., variable-free) and
    nonground aspects. We also added a type system to the calculus. We
    relied on the library for first-order clauses and on the saturation
    framework.

  • Zippy - Generic White-Box Proof Search with Zippers
    by Kevin Kappelmann
    https://www.isa-afp.org/entries/Zippy.html

    This entry contains Zippy, a framework for tree-based searches. Zippy
    is largely independent of concrete search tree representations, search
    algorithms, states and effects. It is designed to create analysable
    and navigable searches that are open to customisation and extensions
    by users. An accompanying arXiv preprint is available here.

    This entry also provides a concrete instantiation of the framework in
    the form of a general purpose white-box prover, called zip. The prover
    performs a proof tree search with customisable expansion actions and
    search strategies, including A, breadth-first, depth-first, and
    best-first search. By default, it integrates the classical reasoner,
    simplifier, the blast and metis prover, and supports resolution with
    higher-order and proof-producing unification, conditional substitutions,
    case splitting, and induction, among other things. Users are free to
    extend the prover with additional expansion actions and search
    strategies. We demonstrate the capabilities of zip in an examples theory.

    In most cases, zip can be used as a drop-in replacement for
    Isabelle's classical methods, including auto, fastforce, force, fast, etc.
    We demonstrate this with a benchmark containing 2267 method calls from
    Isabelle's standard library, where zip achieves a success rate of
    99.82% (2263/2267).

    The Zippy framework is founded on concepts from functional programming
    theory, particularly zippers, arrows, monads, lenses, and coroutines.
    This entry contains a library of mentioned concepts for Isabelle/ML.

Enjoy!
