Checkpoint the party/runtime stack before share-program and malicious-mode work.

Browse source 
Ship the TLS mesh, composer, Beaver/Yao/leaf MPC, prep/online paths, apps, and docs so the tree is pushable before elevating share_expr, security_mode, and prep resume.

"""Cost matrix for libdpf profile harnesses.
Each cell is one named case. Cells are grouped into slices so an optimization
pass can rerun only the code it touched. A label is a directory of results.
Rerunning a slice under the same label replaces those rows and leaves the rest.
Examples:
test/profile/cost_matrix.py --list
test/profile/cost_matrix.py --label baseline
test/profile/cost_matrix.py --label baseline --slice interval
test/profile/cost_matrix.py --label baseline --slice memoizer --slice bits
test/profile/cost_matrix.py --label baseline --family grotto --slice horner
test/profile/cost_matrix.py --label baseline --case interval_u32_L4096
test/profile/cost_matrix.py --label after-horner --slice horner
test/profile/cost_matrix.py --compare baseline after-horner
Tiers:
std default. Benchable party flows, plus every in-process cell.
heavy wildcard_single_leaf, long beaver streams, full-domain DCFs,
and party flows whose names end in _domain.
all std and heavy.
smoke party flows that are negative tests, not cost points.
Default repeats are per slice (party 3, tables 20, walks 12). --repeat
overrides every selected cell.
Columns (blank when not instrumented):
prg_evals, bytes_sent, bytes_recv_from_p2, bytes_recv_from_peer,
rounds (channel exchange barriers; not frames), preprocess_bytes,
alloc_bytes, logical_bytes, layout_waste (alloc-logical),
payload_sent/recv, wire_overhead (framed bytes minus payload).
For p2, bytes_*_from_peer / bytes_*_to_peer sum the p0 and p1 links.
