  1. feat(mcpp.plugins): 0.2.3 — mcpp.rules.ascendc, and the collection's … 

    …floor moves to 2026.9.6.5

The fifth rule, and the first for a vendor this collection had not built for.

Two things in mcpp 2026.9.6.5 are load-bearing for it. `.asc` in the
device-source table, so the engine routes an Ascend C unit to the build program
instead of the C++ compiler. And `mcpp::link_flag`, without which the rule
cannot emit the `-Wl,-rpath-link` that GNU ld needs to resolve the CANN
libraries' own DT_NEEDED entries -- `-L` does not serve that purpose, and the
link fails on `memset_s` and `CheckLogLevel`, symbols of libraries nobody
named. That is why the floor moves rather than staying where 0.2.2 left it.

The rule compiles with BiSheng in MIXED mode rather than `--cce-aicore-only`.
With that flag the output is a Da Vinci object the host linker cannot place;
without it the same source yields a host object carrying the device binary and
a host-callable launcher, which the ordinary link takes -- no registration file
and no device-link step.

Verified on a machine with no Ascend hardware: the kernel compiles, the object
links, and only `libascend_hal.so` is missing, which belongs to the DRIVER and
is exactly what should be absent there.

Both mirrors were downloaded and compared byte for byte before this descriptor
was written; one sha256 names both.
