Saved target natural timeout and input fixture
EXPERIMENTAL / PARTIALLY_FEASIBLE. The protocol and result
defines a single new Mosaic run with one natural timeout episode. The
previous crossing campaign and its exhausted ledger are immutable historical
evidence. This fixture reconstructs the pinned compositor privately, uses a
fixed opaque XDG SHM H2 reference, and stores all generated data under one
new /tmp LAB. No production source, package or installed library is changed.
Run prepare.sh to reconstruct the private binaries without launching a
compositor. Run the offline test-budget.py before the sole run.py LAB
invocation. The runner requires two identical H2 captures before any
transaction reservation, calculates no more than one relative camera delta,
and copies its exact source into the run directory. analyze.py LAB derives
structured results and SHA-256 manifests from retained raw files. Never
reuse an old LAB or reset a consumed ledger.
The sole run used /tmp/swayfx-mosaic-nested-grab-iKwhINe5. Its ledger
records one run, one episode, one camera adjustment and eight captures.
The exact executed Python source is saved as runs/*/fixture-source.py.
The static reference and the target retained their real configure/ACK
processing; the target held serial 50 until natural SwayFX timeout. Its
crossing saved node rendered on H1, the whole H2 RGB image remained
identical before/during/after, and the target tree was destroyed. One H2
pointer sample reached the static reference; the visible H1 sample hit the
saved scene buffer without a Wayland surface. Full damage and native GPU
lifetime remain unqualified. analyze.py is offline only and may be rerun
without spending a graphics budget; run it with PYTHONDONTWRITEBYTECODE=1.
