Drops the ninja dry-run probe (a second full manifest load and stat
sweep per build to suppress one line), the compile-database stamp file
(a plain mtime compare says the same), and the ccache sentinel
(resolve_ccache_path only spawns when it returns a value, so a plain
fallback never re-probes). The crash decoder resolves addr2line and
the ELF once per run instead of once per address, which removes the
module-level warn-dedup dict along with its test fixture. The size
summary uses the toolchain path it was handed rather than re-deriving
it, and its two failure branches merge.
The framework import moves into the functions that need it: the serial
upload and logs fast path resolves this module for artifact paths
alone and was paying 16 ms and 29 modules for the package-download
stack. test_lazy_imports now guards that module so it cannot come
back. analyze-memory's idedata candidate list learns the suffixed
native cache name, and warn_if_idedata_missing goes back to being a
one-for-one extraction.
