MasterJH5574 opened a new pull request, #20094:
URL: https://github.com/apache/tvm/pull/20094

   The bundled `3rdparty/tvm-ffi` gitlink is at `v0.1.13-post2` (#20088), so 
TVM compiles against post2 headers. The wheel does not bundle `libtvm_ffi.so` — 
it is excluded from the auditwheel, delocate and delvewheel repair commands in 
`pyproject.toml` — so the runtime library is whatever the `apache-tvm-ffi` 
dependency resolves to at install time. That makes this floor an ABI contract 
rather than a formality.
   
   `ModuleObj::GetFunction` changed from `virtual Function` to `virtual 
Optional<Function>` between `0.1.13` and `0.1.13.post2` (apache/tvm-ffi#700, 
apache/tvm-ffi#701). That is a C++ vtable boundary whose mangled symbol does 
not encode the return type, so pairing a post2-compiled TVM with an older 
`libtvm_ffi.so` fails silently rather than at link time, and there is no 
runtime version guard that would catch it.
   
   A plain `pip install` already resolves to post2 since pip picks the newest 
match, so this is latent rather than universal; raising the floor closes the 
pinned and constrained resolves that `>=0.1.13` still permits. The same bump is 
included in #20093 for the v0.26.0 release branch.
