The baseline binary, the profile, the Stage 02 save and the caches all live
outside both repos and had been wiped, and sylph-doctor reports 'all good'
without them. This is the recipe, verified by driving it to Stage 02 flight
rather than by inspecting files.
Three things worth having found:
* the baseline is an INCREMENTAL build, not a scratch one -- auto/upstream-baseline
differs from the instrumented branch in 202 files and zero submodule gitlinks,
so checking it out in the shared tree and rebuilding into the existing build dir
takes ~9 min at -j4. git worktree prune first; a dead worktree still claims the
branch.
* the baseline CANNOT make a profile (--create_profile_if_none is one of our 50
commits) and the Sign In dialog cannot be typed into, so bootstrap the profile
with the instrumented binary once and run the baseline against it.
* the Xbox content .header is NOT needed -- ContentManager::ListContent falls back
to the directory name when ReadContentHeaderFile fails, checked in the source.
The LOAD GAME screen then shows date, difficulty, flight time and clear ratio
anyway, which proves those come out of savedata itself. No header was fabricated.
Trap paid for once: keep the file name xenia_canary. A copy saved as
xenia_canary.baseline-... survives every pkill -x in the toolkit and holds the
run-canary lockfile while ps -C xenia_canary shows nothing.
