Comments only, no assertion logic, pins or leg definitions touched.
Reflowed every rationale block to denser wording and removed the
duplication that had built up across repeated steps: the desktop
workflow repeated the fork-PR skip, the desktop-v* tag resolution and
the restore-runner note once per platform, and the installer workflow
repeated its path-filter rationale in both the pull_request and push
blocks. Those now point at the first copy.
Every WHY is kept: why the masked legs avoid install.sh --local, what
UNSLOTH_CI_SOURCE_OVERLAY is for, why `absent` tests "must not work"
rather than command -v, why the .venv_t5_* sidecars are in the macho
scan scope, why the signature check is main-executables-only, why each
nobuild allowlist entry is a pure-Python sdist, why the WSL job gates
and what the pipe truncation was, and why the virgin container's
overlay=false row is still pinned.
Proved comments-only three ways: both workflow revisions parsed with
yaml.safe_load_all and every leaf walked (only `run:` scalars differ);
every changed bash body and .sh compared byte-for-byte after
`bash --pretty-print -n`; every changed pwsh body and .ps1 compared as
a token stream with Comment and NewLine tokens dropped. A negative
control injecting one non-comment line into each layer makes all of
them fail.
